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: An on-demand scheduling request (SR) design is disclosed. Such an on-demand or triggered SR operation provides pre-configuration of user equipments (UEs) with triggered SR resources. Base stations may also configure UEs to monitor for a trigger signal within a bit field of control signaling from the base station. Upon detecting the trigger signal within such bit field, the UEs may use the triggered SR resources for transmitting triggered SR requests. Such use of the triggered SR resources may be in response to UEs detected cancelation of other periodic configured SR resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a grant that schedules multiple downlink communications, wherein the grant includes multiple start and length indicator values (SLIVs) that indicate respective time domain resource allocations (TDRAs) for the multiple downlink communications and a feedback timing indicator that indicates timing of uplink feedback communications for the multiple downlink communications. The UE may determine that there is a conflict between a timing of a first uplink feedback communication for a first downlink communication of the multiple downlink communications and a TDRA for a second downlink communication of the multiple downlink communications. The UE may adjust at least one of the TDRA for the second downlink communication or the timing of the first uplink feedback communication. 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 transmit an indication of a physical downlink control channel (PDCCH) monitoring capability that indicates an amount of time between two consecutive PDCCH monitoring windows, a number of slots to be included in a PDCCH monitoring window, and a number of consecutive symbols in a slot to be associated with PDCCH monitoring. The UE may receive a PDCCH monitoring configuration that is based at least in part on the PDCCH monitoring capability. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine an amount of time between uplink allocations that is needed for performing frequency retuning during operation at a subcarrier spacing (SCS). The UE may perform frequency retuning in association with hopping from a first set of frequency resources, associated with transmitting a first uplink transmission, to a second set of frequency resources, associated with transmitting a second uplink transmission, during operation at the SCS, wherein the frequency retuning is performed during a set of consecutive unallocated resources determined based at least in part on the amount of time between uplink allocations that is needed for performing frequency retuning. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a first UE may be configured to transmit multiple sidelink synchronization signal blocks (S-SSBs) within an S-SSB period, the transmissions back-to-back or non-back-to-back. The first UE may determine one or more listen-before-talk occasions associated with the S-SSBs, participate in at least one listen-before-talk procedure during a listen-before-talk occasion, and transmit the multiple S-SSBs to a second UE. In some other examples, the first UE may identify a reference frequency position of a reference S-SSB in a sidelink BWP. The first UE may transmit the reference S-SSB and one or more additional S-SSBs to a second UE, the one or more additional S-SSBs having frequency positions following the reference frequency position.

Abstract: This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer storage media, for wireless communication. Various aspects relate to initial physical random access channel (PRACH) power control using multiple PRACH signals, and more particularly to supporting one or more initialization and power control operations between a user equipment (UE) and a network entity prior to an association process. The initial PRACH power control may include the UE transmitting, to the network entity, a first set of PRACH signals at different respective power levels. The network entity may transmit a response message indicating a single set of PRACH signals detected by the network entity, and the UE may detect whether a first PRACH signal, of the first set of PRACH signals, is included in the single set of PRACH signals to select a power level associated with the first PRACH signal for transmitting association messages.

Abstract: Aspects relate to configuring and managing hybrid automatic repeat request (HARQ)-acknowledgment (ACK) feedback codebooks for use in wireless communication systems. The HARQ-ACK codebooks include priority-based HARQ-ACK codebooks of differing priorities, such as Type 1 and Type 2 codebooks, and one-shot (Type 3) HARQ-ACK codebooks. In one example, a wireless communication device may be configured to obtain a set of HARQ-ACK codebooks that include priority-based HARQ-ACK codebooks of differing priorities and a separate one-shot HARQ-ACK codebook. The wireless communication device may further be configured to process first and second physical uplink channels based on the priority of the first physical uplink channel and the priority of the second physical uplink channel, where one of the two physical uplink channels includes the one-shot HARQ-ACK codebook, and with the processing performed in combination with the use of the priority-based HARQ-ACK codebooks.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may perform a blind decoding process on a downlink control channel (e.g., a physical downlink control channel (PDCCH)) in a control resource set (CORESET). The UE may receive a configuration indicating that the CORESET is configured with multiple sets of resource element group (REG) bundles, and each set of REG bundles may be associated with a transmission configuration indicator (TCI) state. The UE may map control channel elements (CCEs) of the CORESET to one or more REG bundles of the sets of REG bundles. A PDCCH candidate may be associated with the CORESET, and the UE may determine CCEs for the PDCCH candidate based on the mapping such that the PDCCH candidate includes at least one REG bundle associated with each TCI state. The UE may monitor the PDCCH candidate for downlink control information (DCI).
