Abstract: Various aspects of the present disclosure generally relate to wireless communication. A user equipment (UE) may transmit a random access message including a preamble and a payload. A base station may detect the preamble of the random access message. The base station, and may fail or succeed to decode the payload of the random access message. The base station may transmit, based at least in part on detecting the preamble and the different decoding outcome for the payload, a random access response. The random access response may include an uplink group grant and an indication for a type of the uplink group grant for a plurality of UEs whose preamble transmission share the same time and frequency occasion. UEs may monitor the type and the contents of the uplink group grant and transmit data subsequently on a set of shared time frequency resources. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that a secondary cell (SCell) is to be activated for the UE or switched from a dormant state to an active state, where the SCell is in a discontinuous reception (DRX) group. The UE may set a DRX state for the SCell based at least in part on determining a DRX state of other SCells in the DRX group or determining that there are no existing SCells in the DRX group. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for an enhanced query and response message for a recommended bit rate for uplink and/or downlink streaming. The techniques generally include generating a query message indicating a requested data rate for streaming services, wherein the requested data rate is indicated via a bit rate field and one or more additional bits, and sending the query message to a base station.

Abstract: Certain aspects of the present disclosure provide techniques for time aligning full-duplex communications. A method that may be performed by a base station (BS) includes transmitting, to a first user equipment (UE): an indication of a first uplink timing advance (TA) determined based on a first propagation delay between the BS and the first UE, and an indication of a first cyclic prefix (CP) length determined based on the first uplink TA. In certain aspect, the method also includes transmitting, to the first UE, a first downlink communication comprising a downlink CP, during a first time window comprising a plurality of time periods.

Abstract: Methods, systems, and devices for wireless communications are described for configuring discontinuous reception (DRX) cycles within a DRX time period at a user equipment (UE). DRX configurations may provide that different DRX cycles have non-uniform cycle durations within the DRX time period. Such non-uniform cycle durations may provide DRX ON-durations that are aligned with a periodicity of downlink traffic to the UE in which the downlink traffic may be unaligned with timing boundaries used for wireless communications between the UE and a base station, such as slot boundaries or symbol boundaries.

Abstract: The present disclosure provides for proactive wake-up beam management for connected mode discontinuous reception (C-DRX) operation. For example, a user equipment (UE) monitor one or more synchronization signal blocks (SSBs) or reference signals received associated with a set of wake-up beams from a network entity. The UE may further determine that the set of wake-up beams satisfies a distress condition. The UE may additionally transmit a distress indication to the network entity based on determining that the set of wake-up beams satisfies the distress condition. Aspects described herein also provide a network entity that receives a distress indication from the UE in response to transmitting a set of wake-up beams and transmits a subsequent set of wake-up beams having at least one wake-up beam different not included in the set of wake-up beams to the UE.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a user equipment (UE) to determine a time gap between receiving a paging early indication (PEI) and receiving a paging message based on a link quality of the UE. The UE may determine the time gap based on a number of reference signals the UE may measure after receiving the PEI to obtain channel information for accurately decoding a forthcoming paging message and a periodicity of the reference signals. The UE may transmit UE assistance information (UAI) to the base station during an active state to indicate the time gap. The UE may receive a configuration message from the base station indicating a configured time gap for the UE based on the UAI. The UE may receive the PEI and monitor a paging occasion for the paging message according to the configured time gap.
