Abstract: In one aspect, a method of wireless communication includes receiving, by a user equipment (UE), a preconfigured uplink resource (PUR) configuration message indicating a PUR configuration for small data transmissions. The method also includes determining, by the UE, a PUR configuration release trigger for the PUR configuration. The method further includes receiving, by the UE, a PUR configuration release message configured to release the PUR configuration. In another aspect, a method of wireless communication includes transmitting, by a network entity, a preconfigured uplink resource (PUR) configuration message indicating a PUR configuration for small data transmissions. The method also includes determining, by the network entity, a PUR configuration release trigger for the PUR configuration. The method further includes transmitting, by the network entity, a PUR configuration release message configured to release the PUR configuration. Other aspects are described and claimed.

Abstract: Wireless communication devices, systems, and methods related to mechanisms to implement improved RAR decoding performance and resource utilization efficiency in a RACH procedure. A PDCCH with common search space encodes a DCI with configuration information that schedules separate PDSCHs for different UEs/UE groups. When sending a RAR message, the PDCCH includes a DCI with a configuration field to signal multiple DMRS resources with corresponding PDSCH. Each sub-field of the configuration field may include one or multiple bits. When one bit per sub-field, the bit is a flag that when asserted leads the UE to blind decode the PDSCH associated with that DMRS resource. When multiple bits, it includes a flag field as well as one or more bits that include least significant bits of a UE identifier (or group identifier). The UE locates its identifier (or group identifier), and limits decoding to that PDSCH with corresponding DMRS resource.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive configuration information that indicates a transmission parameter associated with a random access response (RAR) type; transmit a random access message associated with the RAR type; use the transmission parameter to obtain a physical downlink control channel (PDCCH) communication that schedules a physical downlink shared channel (PDSCH) communication that includes a RAR in a medium access control protocol data unit of the PDSCH communication; and obtain or refraining from obtaining the PDSCH communication based at least in part on whether the PDCCH communication is successfully obtained using the transmission parameter. Numerous other aspects are provided.

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 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.
