Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an AMF may receive, from a user equipment (UE), a communication associated with a request for an identifier. The AMF may transmit, to the UE, the identifier, wherein the identifier is based at least in part on a synchronization signal block (SSB) periodicity and a number of paging frames per discontinuous reception (DRX) cycle. Numerous other aspects are described.

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: An UE transmits at least one UE configuration parameter to a base station comprising at least one preferred parameter for a UE configuration, e.g., in addition to a preferred setting for a delay budget report. The UE then receives a configuration from the base station based, at least in part, on the at least one UE configuration parameter transmitted to the base station. Additionally, a base station receives the at least one UE configuration parameter from a UE comprising at least one preferred parameter for a UE configuration, e.g., in addition to a preferred setting for a delay budget report. The base station then configures the UE using the at least one UE configuration parameter received from the UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration that indicates a duration of a dormancy timer for switching from an active bandwidth part to a dormant bandwidth part configured for the UE; start or restart the dormancy timer based at least in part on a determination that a condition is satisfied; and switch to the dormant bandwidth part based at least in part on a determination that the dormancy timer has expired. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may configure a physical downlink control channel (PDCCH) component of a message B (msgB) communication to include a first portion of the signaling information for physical uplink control channel (PUCCH) for hybrid automatic repeat request (HARQ) feedback associated with the msgB communication and the signaling information for HARQ combining of msgB. The BS may configure a physical downlink shared channel (PDSCH) component of the msgB communication to include a second portion of the signaling information for PUCCH and msgB HARQ combining. The distributed mapping for the signaling information to the PDCCH and PDSCH components of msgB can be indicated by system information, RRC signaling, or hard coded in specifications. The BS may transmit the msgB communication to one or more UEs. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a random access radio network temporary identifier (RA-RNTI), associated with a random access channel (RACH) procedure, based at least in part on: a radio frame index associated with a RACH occasion in which a RACH preamble is transmitted during the RACH procedure, or a type of the RACH procedure; and receive a random access message based at least in part on the RA-RNTI. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for a configurable mode for a response to random access message. A method that may be performed by a user equipment (UE) includes receiving an indication from a base station (BS) that the BS operates according to a first mode in which the BS unicasts a RACH response during a two-step RACH procedure or a second mode in which the BS multicasts the RACH response. The RACH response includes a PDCCH and PDSCH. The UE sends a RACH message to the BS comprising a preamble and payload. The UE monitors and decodes the PDCCH of the RACH response based on the indicated first mode or second mode. The UE decodes the PDSCH of the RACH response and sends feedback to the BS based on the indicated first mode or second mode.

Abstract: Certain aspects of the present disclosure provide techniques for a hybrid automatic repeat request (HARQ) procedure for the random access channel (RACH) response message in a two-step RACH procedure. A method that may be performed by a user equipment (UE) includes sending a RACH message to a base station (BS) during a two-step RACH procedure. The RACH message includes a RACH preamble and a RACH payload. The UE monitors a RACH response message from the BS during a random access response (RAR) window. The UE transmits a retransmission of the RACH message, an acknowledgement (ACK) to the RACH response message, a negative acknowledgment (NACK) to the RACH response message, or does not transmit, to the BS based on whether a RACH response message carrying a success RAR or a fallback RAR, or no RACH response message, is received from the BS during the window.

Abstract: A UE initiates a PUSCH transmission determination procedure if at least one of a first PUSCH overlaps with a second PUSCH in a transmission and a first PUCCH overlaps with the first PUSCH or the second PUSCH, or if the first PUCCH overlaps with at least one of the first PUSCH or the second PUSCH in the transmission and the first PUSCH and the second PUSCH are not overlapped with each other, the first PUSCH and the second PUSCH being associated with different uplink priorities. The UE multiplexes the first PUCCH with the first PUSCH or the second PUSCH that overlaps with the first PUCCH. The UE transmits the first PUSCH or the second PUSCH based on at least one of the uplink priorities associated with the first PUSCH and the second PUSCH or uplink priorities associated with the first PUCCH and a second PUCCH.

Abstract: Aspects described herein relate to receiving a configuration indicating multiple association rules associating random access preambles and payload formats, selecting, as part of a random access procedure, a random access preamble from the random access preambles for transmitting over a random access occasion, determining, based at least in part on at least one of the association rules in the configuration, a payload format associated with the random access preamble and a corresponding payload resource unit, and transmitting the random access preamble over the random access occasion and, according to the payload format, an associated payload over the corresponding payload resource unit. Multiplexing of payload resource units with same or different payload formats can be performed in time, frequency and code domains, based on the received configuration.
