Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a throttling indicator for a shared resource associated with a modem at the UE. The CE may determine a configuration of the modem based on a configuration received from a Radio Resource Control layer of the UE. Based on the modem configuration and the throttling indicator, the UE may identify a throttling level to apply to the modem. The UE may adjust the modem configuration for communicating with a base station based on the throttling level in order to reduce resource usage below a usage threshold. By reducing usage of the shared resource by the modem, the UE may have a greater availability of the shared resource to meet the needs of other components of the UE. This may provide an improved user experience at the UE, among other benefits.

Modem throughput throttling

Aspects of the present disclosure relate to optimization of packet processing when packets are received out of order in sequence. For example, a user equipment (UE) may determine whether a difference between a sequence number of a first packet and a sequence number of a second packet received subsequent to receiving the first packet exceeds a sequence jump threshold. The UE may disregard the second packet from processing in response to at least determining that the difference is greater than the sequence jump threshold. The UE may receive and process a plurality of packets respectively associated with a plurality of sequence numbers that are greater than the sequence number of the first packet and less than the sequence number of the second packet.

Downlink data stall optimization by addressing an out-of-order packet sequence

Certain aspects of the present disclosure provide a method for wireless communication by a user equipment (UE). The UE starts a first timer (such as a discontinuous reception (DRX) hybrid automatic repeat request (HARQ) round-trip-time (RTT) timer), after sending an uplink (UL) data transmission to a network entity. The UE then starts a second timer (such as a DRX retransmission timer) when the first timer expires. The UE then determines whether to wake up or sleep for a duration of the second timer based on a prior block error rate (BLER).

Power savings for voice services

A method of wireless communication performed by a user equipment (UE) includes: operating in a Dual SIM Dual Active (DSDA) mode or a Dual SIM Dual Standby (DSDS) mode in which a first subscriber identity module (SIM) is designated as a default data subscription (DDS); determining a recommendation to change the DDS from the first SIM to a second SIM at a modem; informing a user of the recommendation to change the DDS; changing the DDS in response to, at least in part, the recommendation and an input from the user; updating a first state variable to indicate a state of the DDS; and routing internet data to the second SIM.

Management of default data subscription (DDS) in multi-subscriber identity module devices

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain one or more communication parameters associated with one or more communications to be transmitted by the UE. The UE may transmit the one or more communications based at least in part on a congestion control algorithm selected from a set of candidate congestion control algorithms, the congestion control algorithm selected based at least in part on the one or more communication parameters. Numerous other aspects are described.

Congestion control algorithms

Aspects of the present disclosure provide example apparatus, methods, processing systems, and computer readable mediums implementing techniques for modifying a configuration of a radio bearer based on a request for quality of service (QoS) for a communication flow. In aspects, a user equipment (UE) receives a request for a QoS for a communication flow and maps the communication flow to a radio bearer based on a downlink map. The UE is configured to communicate over a number of radio bearers. The downlink map associates one or more communication flows to one or more of the number of radio bearers. The UE then modifies a configuration of the radio bearer based on the request for the QoS. During operation, the UE receives one or more downlink packets on the radio bearer and processes the one or more downlink packets according to the QoS.

Modifying a configuration of a radio bearer based on a request for quality of service (QOS) for a communication flow

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify an available energy for uplink transmission of a plurality of communication links of the UE. The UE may configure, from the available energy, a first set of energy allocations for the plurality of communication links. The UE may configure a second set of energy allocations for one or more communication links of the plurality of communication links, wherein the second set of energy allocations are allocated from a remainder of the available energy after the first set of energy allocations are allocated. The UE may transmit based at least in part on at least one of the first set of energy allocations or the second set of energy allocations. Numerous other aspects are described.

Techniques for per communication link energy reservation

Methods, systems, and devices for wireless communication are described. In some wireless communications systems, a receiving device, such as a user equipment (UE), may reduce packet congestion associated with communications between the receiving device and a transmitting device, such as a server, via a radio access network (RAN). The receiving device may measure congestion metrics associated with receiving data packets from the transmitting device via the RAN. The congestion metrics may include RAN congestion metrics and transport or application layer congestion metrics associated with the network connection between the receiving device and the transmitting device. The receiving device may estimate packet congestion at the receiving device according to the measured congestion metrics. The receiving device may modify connection parameters of the network connection based on the estimated packet congestion. The receiving device may communicate with the transmitting device over the network connection in accordance with the modified connection parameters.

Downlink congestion control optimization

In an embodiment, a UE receives a first uplink grant for a first RAT (e.g., 5G NR) and a second uplink grant for a second RAT (e.g., LTE). In one embodiment, the UE schedules an uplink transmission on the first RAT (e.g., by selectively dropping the uplink transmission on particular resource blocks) so as to manage an amount of time that is based on concurrent uplink transmissions on both the first and second RATs are performed. In another embodiment, the UE establishes a first period of time where a BSR transmitted by the UE on the first RAT is adjusted based on scheduling of concurrent uplink multi-RAT transmissions, and a second period of time where no BSR is transmitted by the UE on the first RAT based where concurrent uplink transmissions on both the first and second RATs are not permitted to be scheduled.

Managing concurrent multi-rat uplink transmissions at a user equipment

Methods, systems, and devices for wireless communication are described. Semi-persistent scheduling (SPS) configurations that enable uplink transmissions during different transmission time intervals (TTIs) may be used. For example, a base station may configure SPS for a set of TTIs, where the configuration may include a periodicity between shortened TTIs (sTTIs) (e.g., two-symbol, three-symbol, seven-symbol TTIs, etc.) that may be used by a user equipment (UE) for uplink transmissions. The base station may signal the SPS configuration to the UE, and the UE may then identify locations of TTIs for use in SPS transmissions. For instance, the UE may identify the location of a set of sTTIs that are designated for SPS and that occur at a certain periodicity indicated by the configuration. Upon identifying the TTI locations, the UE may transmit uplink data during one or more of the identified TTIs in accordance with the periodicity.

Periodic grants for multiple transmission time interval configurations

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may initiate a first service, having a first priority during a time interval, associated with a first subscriber identification module (SIM), and a second service, having a second priority during the time interval, associated with a second SIM of the UE, the first priority having a higher priority than the second priority. The UE may identify a first type of communication associated with the second SIM. The UE may adjust, based at least in part on the first type of communication, at least one of the first priority or the second priority during the time interval. The UE may perform a communication in accordance with the adjusted at least one of the first priority or the second priority. Numerous other aspects are described.

Techniques for dual active subscriber transmit sharing

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may initiate a first service associated with a first subscriber identity module (SIM) of the UE and a first priority. The UE may initiate a second service associated with a second SIM of the UE and a second priority. The UE may switch the first priority and the second priority during at least part of the first service or the second service. The UE may perform a communication in accordance with at least one of the first priority or the second priority. Numerous other aspects are described.

Techniques for prioritizing communications for dual subscriber user equipment

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify that uplink data is available for transmission at the UE prior to a scheduling request occasion. The UE may skip transmission of a scheduling request during the scheduling request occasion based on identifying that an uplink grant is pending. The UE may transmit at least a portion of the uplink data to a base station using a resource allocation indicated by the uplink grant. Alternatively, the UE may transmit the scheduling request to the base station during a first scheduling request occasion. The UE may initiate a retransmission timer based on transmitting the scheduling request. Accordingly, the UE may skip retransmission of the scheduling request during a second scheduling request occasion that is subsequent to the first scheduling request occasion based on the retransmission timer.

Techniques for skipping scheduling requests

Disclosed are systems and techniques for wireless communications. For instance, a wireless device may receive a signal from a first wireless network while the wireless device is in an idle mode; determine, from the received signal, a signal to noise ratio (SNR) and a doppler shift; retrieve stored network capability information; and estimate, based on the SNR, the doppler shift, and the stored network capability information, a throughput of the first wireless network.

Idle mode throughput projection using physical layer measurements

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, via a first carrier associated with a first radio access technology, at least a first uplink grant from a base station. The UE may implement one or more backoff schemes. For example, the UE may transmit, using resources indicated by at least the first uplink grant, an uplink message based on a temperature of one or more components of the UE satisfying a threshold, the uplink message including a transport block (TB) indicating data, a buffer status report (BSR) associated with the data, one or more padding bytes different from the data, or any combination thereof. The UE may monitor for at least a second uplink grant from the base station during a first time period based on transmitting the uplink message.
