Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a message indicating that the UE is to execute a make-before-break handover procedure. The UE may transmit, during the make-before-break handover procedure and based at least in part on a prioritization rule, a first uplink communication to a target base station. The prioritization rule may indicate a relative priority for different uplink communications included in a group of uplink communications. The group of uplink communications may include at least the first uplink communication to be transmitted by the UE to the target base station and a second uplink communication to be transmitted by the UE to a source base station during the make-before-break handover procedure. Numerous other aspects are described.

Abstract: This disclosure provides systems, methods, and apparatuses to enable a user equipment (UE) and a base station to improve reception of a random access response (RAR) by the UE in an unlicensed spectrum. A network may define a procedure for calculating a random access radio network temporary identifier (RA-RNTI) specific to unlicensed spectrum based on an extended RAR window. The calculation procedure may allow UEs transmitting in the window to calculate a unique RA-RNTI and identify a RAR addressed to the UE using the unique RA-RNTI. Additionally, or alternatively, a base station may transmit a RAR including timing information associated with a corresponding random access request. Accordingly, a UE may receive the RAR and compare the timing information with its own random access request in order to determine whether the RAR is addressed to the UE. Additionally, a UE may monitor a secondary cell or a sub-band for the RAR.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication of a configuration for a set of random access channel (RACH) procedure types for a bandwidth part of the UE, each RACH procedure type in the set of RACH procedure types being different from at least some if not all the other RACH procedure types in the set of RACH procedure types. The UE may select a RACH procedure type from the set of RACH procedure types for the RACH procedure based at least in part on the indication of the configuration for the set of RACH procedure types and on a trigger to perform a RACH procedure for a network slice. The UE may perform the RACH procedure for the network slice according to the RACH procedure type.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, in a radio resource control (RRC) idle mode or an RRC inactive mode, a paging message that includes an indication identifying an intended slice for a protocol data unit (PDU) session associated with downlink traffic for the UE. The UE may transmit, to a base station, a request to initiate a random access channel (RACH) procedure based at least in part on the intended slice. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may support carrier aggregation for a sidelink control connection, such as a PC5 or radio resource control (RRC) connection with another UE. The sidelink control connection may support at least two sidelink control carriers, such as an anchor sidelink carrier, a secondary or selected sidelink carrier, a secondary anchor sidelink carrier that may be configured for fallback or duplication, among others. The sidelink control connection may be monitored for radio link failure and a secondary sidelink carrier may be used. Other sidelink carriers may be configured for the sidelink control connection as channel conditions change.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may perform a channel access procedure associated with a transmission of a sidelink communication that is to be associated with resources that are associated with a first configured grant configuration, wherein the channel access procedure is unsuccessful, wherein the sidelink communication is associated with a hybrid automatic repeat request (HARQ) process identifier, and wherein a state associated with the HARQ process identifier is changed to pending based on the channel access procedure being unsuccessful. The UE may transmit, based on successfully performing another channel access procedure, a retransmission of the sidelink communication using resources associated with the first configured grant configuration or a second configured grant configuration based on the state associated with the HARQ process identifier being changed to pending. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station as part of a wireless communications system. The UE may receive a downlink message from a base station. The UE may perform a decoding procedure for the received downlink message. The UE may determine the downlink message has a traffic type associated with a quality of service level. The UE may determine to transmit enhanced feedback with an acknowledgment message (positive or negative) indicating the result of the decoding procedure for the received downlink message, in cases where the downlink message is of the first traffic type. The enhanced feedback may indicate assistance information associated with a quality of service level for the received downlink message. The UE may then transmit the enhanced feedback for the acknowledgment message.

Abstract: Wireless communications systems and methods related to multiplexing a sidelink-synchronization signal block (S-SSB) transmission with a physical sidelink control channel (PSCCH)/physical sidelink shared channel (PSSCH) transmission for occupancy channel bandwidth (OCB) fulfilment are provided. A user equipment (UE) determines a multiplex configuration for multiplexing a sidelink transmission with a S-SSB transmission in a sidelink bandwidth part (BWP). The UE communicates, in the sidelink BWP during a sidelink slot, the S-SSB transmission. The UE communicates, in the sidelink BWP during the sidelink slot, the sidelink transmission, where the S-SSB transmission and the sidelink transmission are communicated by multiplexing the sidelink transmission and the S-SSB transmission based on the multiplex configuration.
