Abstract: Aspects are provided which enhance Mode 2 multi-TRP operation by allowing a UE to recover and reconfigure a failed PDCCH beam of a first TRP in a serving cell by using a second TRP which still has a working PDCCH in the same serving cell. If the first TRP undergoes beam failure but the second TRP in the same cell has an operational beam, the UE may send a beam failure indication indicating a new beam for the PDCCH of the first TRP. The base station comprising the second TRP may then reconfigure the PDCCH serving beams of the first TRP based on the beam failure indication. The reliability of a serving cell may thus be increased.

Abstract: Methods, systems, and devices for wireless communications in a multiple bandwidth part environment are described. In response to a serving beam failure in an active bandwidth part, the UE may determine a level of support provided by the active bandwidth part for a random access procedure, and may determine a contingency (e.g. fallback) bandwidth part that supports the random access procedure. In some cases, the UE may identify the contingency bandwidth as an initial bandwidth part used by the UE for a prior random access procedure. In some cases, the base station may send to the UE, an explicit indication of the contingency bandwidth part. In some cases, the UE may identify the contingency bandwidth part based on a reference signal. Upon determining the contingency bandwidth part, the UE may perform the random access procedure using the contingency bandwidth part.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to receive a broadcast message from a base station, the broadcast message including an indication pertaining to system information for reduced-capability UEs including UEs with a bandwidth capability below a threshold, the UE being a reduced-capability UE. The UE may determine, based on the indication in the broadcast message, whether system information for reduced-capability UEs is scheduled to be broadcast by the base station. The UE may then obtain the system information for reduced-capability UEs in accordance with the indication in the broadcast message.

Abstract: In an aspect, a slave UE and a master UE each establish an attachment to a core network of a cellular communications system. The slave UE obtains security credentials configured to encrypt and decrypt traffic between the slave UE and the core network. A D2D connection is established between the slave UE and the master UE (e.g., tethering). One or more communication functions are offloaded from the slave UE to the master UE, including at least one communication function with the core network for maintaining the attachment of the slave UE to the core network. Application-layer data is relayed to/from the slave UE over the D2D connection. In an aspect, either the slave UE or the master UE may perform encryption and decryption of control plane signaling using the slave UE's security credentials.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine whether a flag is enabled or is disabled, the flag indicating whether channel state information (CSI) associated with a secondary discontinuous reception (DRX) group is permitted to be transmitted outside of an active time associated with a primary DRX group. The UE may selectively transmit the CSI associated with the secondary DRX group in an uplink communication associated with the primary DRX group based at least in part on whether the flag is enabled or is disabled. Numerous other aspects are provided.

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.

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.
