Methods, systems, and devices for wireless communications are described. A user equipment (UE) may adaptively switch between hybrid automatic repeat request (HARQ) monitoring modes to support power savings. In a first HARQ skipping mode, the UE may transmit an uplink message corresponding to a HARQ identifier and may receive a positive acknowledgment (ACK) message in a HARQ monitoring occasion associated with the HARQ identifier. Upon receiving the ACK message, the UE refrains from monitoring a subsequent HARQ monitoring occasion associated with the HARQ identifier while in the first HARQ skipping mode (e.g., an aggressive HARQ skipping mode). The UE may periodically enter a periodic evaluation mode from the first HARQ skipping mode, in which the UE monitors a subsequent HARQ monitoring occasion after receiving an ACK message to check for false ACK messages. If a false ACK message is detected, the UE enters a first HARQ skipping prohibited mode.

Techniques for controlling hybrid automatic repeat request (HARQ)

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify, based at least in part a determination to transmit one or more packets, a scheduling request (SR) occasion in which to transmit an SR for uplink resources to transmit the one or more packets, the SR occasion occurring prior to a start of a connected discontinuous reception (CDRX) on duration of the UE. The UE may determine whether the SR occasion occurs within a threshold amount of time prior to the start of the CDRX on duration of the UE. The UE may transmit the SR in the SR occasion based at least in part on the determination of whether the SR occasion occurs within the threshold amount of time prior to the start of the CDRX on duration of the UE. Numerous other aspects are provided.

Techniques for identifying a scheduling request occasion for connected discontinuous reception

Aspects of the present disclosure provide techniques to enable enhanced machine type communication (s) (eMTC) and/or narrowband Internet-of-Things (NB-IoT) devices to transition to idle mode after releasing a connection, such as a radio resource control (RRC) connection, more quickly than with previously known techniques. An example method includes determining, based on an indication received in a narrowband signal on a narrowband region of a bandwidth comprising a plurality of narrowband regions, whether to wait for a delay period, determined based on a configuration received from a network entity, before releasing a radio resource control (RRC) connection and releasing the RRC connection at a time in accordance with the determination.

Embodiments include systems and methods for performing selection of a transport format combination by a device processor of a wireless communication device. The device processor may determine whether radio frequency self-jamming interference is detected at the receiver of the wireless communication device. The device processor may calculate an average transmit power reduction in response to determining that radio frequency self-jamming interference is detected at a receiver of the wireless communication device. The device processor may select a transport format combination based on the calculated average transmit power reduction, and may use the selected transport format combination to transmit data to a communication network.

Aspects of mitigating throughput degradation during wireless communication include determining that a first transmission signal fails decoding at a network entity due to transmit (TX) blanking when a user equipment (UE) supports dual subscriber identity module dual active (DSDA) and is operating in hybrid automatic repeat request (HARQ) with incremental redundancy; determining whether a first retransmission signal for the first transmission signal fails decoding at the network entity; and retransmitting the first transmission signal as a new transmission signal when a determination is made that the first retransmission signal for the first transmission signal fails decoding at the network entity.

Mitigating the impact of transmit blanking during uplink communications

Aspects related to allocating transmission power in wireless communications are described. It can be determined whether data is to be transmitted on an uplink control channel in one or more upcoming transmission time intervals (TTIs). Based on this determination, transmission power is allocated to an uplink enhanced dedicated channel in the one or more upcoming TTIs. Where uplink control channel data is not to be transmitted in the one or more upcoming TTIs, transmission power that would have been used for the uplink control channels can instead be allocated to the enhanced dedicated channel.

Techniques for optimizing transmission power allocation in wireless communications

In an aspect, this disclosure provides for determining a power imbalance between a first radio frequency (RF) carrier and a second RF carrier of a dedicated physical control channel for uplink transmission, determining whether the power imbalance is greater than a power imbalance threshold, and blocking data transmission on one of the first RF carrier or the second RF carrier when the power imbalance is greater than the power imbalance threshold.

Techniques for prioritizing non-scheduled data are described. Non-scheduled data to be transmitted on a non-scheduled MAC-d flow having a non-scheduled priority and scheduled data to be transmitted on a scheduled MAC-d flow having a scheduled priority may be identified by a user equipment (UE). The UE may transmit the non-scheduled MAC-d flow and the scheduled MAC-d flow according to a priority condition. In one aspect, the UE may receive a pre-allocation of power associated with a non-empty non-scheduled MAC-d flow. Based on a priority condition that the non-scheduled priority is a highest priority, the UE may apply all of the pre-allocation of power when transmitting the non-scheduled MAC-d flow. In one aspect, based on a priority condition that the non-scheduled priority is a lower priority, the UE may adjust the non-scheduled priority and/or the scheduled priority so that the non-scheduled priority is a higher priority.

Apparatus and method for prioritizing non-scheduled data in a wireless communications network

A user equipment (UE) and a method of using the UE are provided for fulfilling a network's intent to increase or decrease the serving grant for the UE in spite of a deadlock condition that may otherwise prevent fulfillment of the network's intent. That is, upon determining the network's intent, the UE may alter its serving grant according the intent by altering the number of packets for transmission in a TTI.
