Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, control signaling for communications in a wireless communications system. The control signaling may indicate a first duration for an inactivity timer. The UE may initiate the inactivity timer and a second timer based on identifying a period of inactivity. The second timer may have a second duration that is shorter than the first duration for the inactivity timer. In some examples, the second duration may be based on one or more parameters, such as a display status, a battery status, a scaling factor, the first duration, an application state, or any combination thereof. The UE may release a connection for the communications in the wireless communications system based on an expiration of the second timer, an expiration of the inactivity timer, or a combination thereof.

Enhanced connection release techniques for wireless communications systems

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit, to a base station, a UE capability message associated with a number of downlink multiple-input and multiple-output (MIMO) layers supported at the UE. The UE may receive a configuration for a set of downlink MIMO layers including a first subset of downlink MIMO layers configured for a first cell and a second subset of downlink MIMO layers configured for a second cell. The UE may allocate a first set of resources to the first cell or the second cell, or both, based on the first and the second subset of downlink MIMO layers. The UE may determine a second set of resources are unallocated to the set of downlink MIMO layers and allocate the second set of resources to the first cell or the second cell, or both.

Techniques to allocate receive resources

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

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, an indication that a cell associated with the base station does not support reduced capability UEs, wherein the UE is capable of operating in a first mode that is associated with reduced capability UEs and a second mode that is not associated with reduced capability UEs. The UE may communicate, in the second mode, with the base station to establish a connection with the cell based at least in part on at least one of: the UE supporting one or more capabilities associated with connecting with the cell, or no cells that support reduced capability UEs being available. Numerous other aspects are described.

Reduced capability user equipment operations

Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for optimizing procedures to update a UE radio capability ID (URCID) when a UE moves to a new Public Land Mobile Network (PLMN) within a registration area. The techniques may help avoid unnecessary signaling traffic and reduce UE power consumption. An example method performed by a user equipment (UE) generally includes receiving at least one URCID assigned by a first PLMN; and taking one or more actions to delay or avoid updating the URCID when moving to a second PLMN in a same registration area as the first PLMN.

Delaying UE radio capability ID (URCID) update for EPLMN

Methods, systems, and devices for wireless communications are described. For example, the described techniques provide for a user equipment (UE) to predict a gain state for an initial acquisition procedure. For example, the UE may use a machine learning (ML) model to predict an initial gain state which is likely to result in a successful initial acquisition procedure (e.g., without adjusting the gain state and reattempting the initial acquisition procedure). The UE may input UE history data or crowdsourced data (e.g., from a local network or a cloud-based server) into the ML model to generate a predicted gain state which may be more likely to result in a successful initial acquisition (e.g., without reattempting the initial acquisition procedure). The UE may use the initial gain state generated by the ML model to attempt an initial acquisition procedure with a network entity.

Efficient initial acquisition with gain state prediction using machine learning

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

Methods, systems, and devices for wireless communications are described. The method may include a user equipment (UE) generating a set of multimedia packets including a first multimedia packet and a second multimedia packet that is generated after the first multimedia packet. The UE may add the set of multimedia packets to a queue and apply an uplink packet handling protocol. Using the uplink packet handling protocol, the UE may discard the first multimedia packet and transmit, to a base station, the second multimedia packet. Using the second multimedia packet, a server in communication with the base station may generate a video frame and transmit the video frame to the UE via the base station.

Techniques for multimedia uplink packet handling

Certain aspects of the present disclosure provide techniques for signaling and scheduling to enable network configured small gaps in intra-band inter-frequency measurement. A method that may be performed by a user equipment (UE) includes receiving, from a serving cell operating on a first frequency, an indication that synchronization signal block (SSB) indexes of a target cell operating on a second frequency can be derived from timing of the serving cell; and deriving an SSB index of the target cell, based on the timing of the serving cell.

Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may transmit assistance information to a base station to request an update or a modification to one or more communication parameters configured at the UE. Such communication parameters may include a quantity of uplink multiple-input multiple-output (MIMO) layers, a quantity of downlink MIMO layers, a minimum scheduling offset, a maximum quantity of component carriers, or a maximum aggregated bandwidth for a secondary cell group (SCG). In some implementations, the UE may transmit the assistance information requesting the update or modification to one or more of such communication parameters based on detecting that the UE satisfies one or more triggering conditions or thresholds.
