Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration for a control resource set (CORESET) that indicates a precoder granularity unit over which a same precoding is used for resources of the CORESET. The precoder granularity unit may be greater than a resource element group bundle of the CORESET and less than contiguous resource blocks of the CORESET. The UE may monitor for one or more physical downlink control channel candidates according to the configuration. Numerous other aspects are provided.

Control resource set precoding indication

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media for a reduced capability (RedCap) user equipment (UE) and supporting cell. The RedCap UE is configured with multiple bandwidth parts (BWPs). A maximum bandwidth of the RedCap UE is lower than a maximum bandwidth of a non-RedCap UEs. The UE receives a cell-defining synchronization signal block (CD-SSB) that defines a shared initial downlink BWP for RedCap UEs and non-RedCap UEs. The UE switches to a separate initial downlink BWP for RedCap UEs. The UE accesses the cell via the separate initial downlink BWP. The UE receives a configuration of an active downlink BWP for RedCap UEs. The UE determines whether to switch from the active downlink BWP to the shared initial BWP or the separate initial downlink BWP to obtain information such as updated system information, system measurements, and uplink configuration information.

Selection of different initial bandwidth parts for reduced capability user equipment

A UE may receive an indication of a first assignment of a first PDSCH via a PBCH from a network entity. The first PDSCH may include at least a first portion of a SIB. The UE may receive the first portion of the SIB via the first PDSCH from the network entity based on the first assignment of the first PDSCH. The first portion of the SIB may include access control information for the network entity and the assignment for a second portion of the SIB. The UE may identify whether the UE is permitted to access the network entity based on the access control information for the network entity.

Structure of minimum SI

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a cyclic shift configuration for one or more repetitions of a non-interleaved control resource set (CORESET), and monitor for one or more physical downlink control channel candidates in the one or more repetitions of the non-interleaved CORESET based at least in part on determining the cyclic shift configuration for the one or more repetitions. Numerous other aspects are provided.

Repetition specific cyclic shifting of a non-interleaved control resource set

Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for efficiently reporting channel state information (CSI) with limited overhead. In one aspect, if a user equipment (UE) is configured to transmit data and CSI to a base station periodically, the UE may transmit the CSI when the UE has data to transmit to the base station. In particular, the UE may transmit data and a CSI report during a transmission opportunity if the UE has data to transmit in the transmission opportunity. Otherwise, the UE may suppress transmission of the CSI report. In another aspect, a UE may be configured to transmit CSI to a base station when downlink channel conditions change. In particular, the UE may request to report CSI to the base station when channel conditions change, and the base station may trigger the UE to report the CSI after receiving the request.

Channel state information triggering for uplink dominant traffic

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may transmit, to a base station, an indication of a selected random access channel (RACH) procedure that is selected based at least in part on positioning state information (PSI) associated with the UE, wherein the PSI is based at least in part on one or more positioning measurements obtained by the UE; and receive, from the base station, a configuration of resources for the selected RACH procedure. Numerous other aspects are provided.

Positioning aided new radio race procedure

Disclosed are techniques for wireless communication. In an aspect, a UE transmits a DSS capability indication to a network entity (e.g., base station), which determines scheduling information for resources of a DSS carrier based on the DSS capability indication. In another aspect, a BS transmits RAT-specific (e.g., LTE-specific) information associated with a DL RS (e.g., LTE CRS) to a UE, which processes the DL RS on a DSS carrier based at least in part on the RAT-specific information.

Signaling related to dynamic spectrum sharing carrier

Various aspects of the present disclosure generally relate to configurations for new radio (NR) devices with reduced capabilities. In some aspects, a user equipment (UE) may determine a configuration from stored configuration information, where the configuration specifies a subset of features that NR UE with reduced capabilities is to support. The UE may communicate according to the configuration of reduced capabilities, or fall back to a set of further reduced UE capabilities. Numerous other aspects are provided.

Capability configurations for new radio redcap devices

Certain aspects of the present disclosure provide techniques for wireless communication by a user equipment (UE), generally including receiving, from a network entity, a configuration for a first downlink (DL) bandwidth part (BWP), a first control resource set (CORESET) configured on the first DL BWP, and one or more first search space (SS) sets within the first CORESET, receiving, from the network entity, a configuration for a second downlink BWP, a second CORESET configured on the second DL BWP, and one or more second SS sets within the second CORESET, receiving signaling configuring the UE for physical downlink control channel (PDCCH) monitoring adaptation, and monitoring for PDCCHs, subject to the PDCCH monitoring adaptation, when performing one or more idle mode or inactive mode procedures on at least one of the first DL BWP or the second DL BWP.

Idle/inactive mode procedures for reduced capability user equipment

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media for a user equipment (UE), which may include a reduced capability (RedCap) UE, and a supporting cell. The UE may receive a synchronization signal block (SSB). The UE may receive a configuration of an active downlink bandwidth part (BWP) that is not configured with a SSB. The UE may tune, from the active downlink BWP to a different frequency for a layer 1 (L1) measurement gap defined by a L1 measurement gap configuration. The UE may perform a L1 measurement of the SSB on the different frequency during the L1 measurement gap. The UE may be a RedCap UE, the active BWP may be for RedCap UEs, and the SSB may define an initial BWP for the RedCap UEs and non-RedCap UEs, and the different frequency may be the initial BWP.

Measurement gaps for L1 measurements

This disclosure relates to methods, devices, and systems for wireless communications, and more particularly to aggregating physical uplink shared channel (PUSCH) resource units relating to a random access message. A user equipment (UE) may identify a random access message of a random access procedure. The random access message may include a random access preamble and a random access payload. The UE may aggregate multiple PUSCH resource units of a set of PUSCH resource units associated with one or more PUSCH occasions (POs) based on one or more of a payload size of the random access payload or a modulation and coding scheme associated with the random access payload. As a result, the UE may transmit the random access payload of the random access message on a PUSCH using time and frequency resources of the aggregated multiple PUSCH resource units over the one or more POs.

Aggregated uplink shared channel transmission for two step random access channel procedure

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a resource for a joint uplink transmission comprising a sounding reference signal and a scheduling request. The UE may receive a grant of a set of resources for an uplink data transmission to a base station. The UE may perform the joint uplink transmission comprising the sounding reference signal and the scheduling request using the resource for the joint uplink transmission in connection with performing the uplink data transmission using the set of resources for the uplink.

Latency reduction and coverage enhancement for extended reality

Some aspects described herein relate to receiving, from a base station, a configuration to transmit uplink signaling to the base station, determining, based on the configuration, to setup a group for sidelink communication with one or more other user equipments (UEs), transmitting, based on determining to setup the group, a first uplink message based on the configuration from the base station, and receiving, from the one or more other UEs, a second uplink message based on the configuration to indicate setup of the group. Some aspects described herein also relate to conflict avoidance between sidelink and uplink/downlink communications.

Techniques for improving efficiency in sidelink wireless communications

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may determine that a distance between an end of a first downlink control information (DCI) and a corresponding first physical downlink shared channel (PDSCH) and a distance between an end of a second DCI and a corresponding second PDSCH satisfy a minimum distance threshold for a user equipment (UE). The ends of the DCIs are to be received at the same symbol. The base station may transmit the first DCI, the first PDSCH, the second DCI, and the second PDSCH based at least in part on determining that the distances satisfy the minimum distance threshold. In some aspects, the UE may decode the first and second DCIs in an order that depends on DCI properties. Numerous other aspects are provided.
