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.

A user equipment (UE) may receive a message that indicates a first initial uplink bandwidth part for use by the UE in communications with a network entity, the message also indicating a plurality of random access occasions, at least one of the plurality of random access occasions being in frequency resources that are outside of the first initial uplink bandwidth part. The UE may select a random access occasion of the plurality of random access occasions for transmission of a random access preamble from the UE to the network entity. The UE may transmit, as part of a random access procedure, the random access preamble within the random access occasion.

Bandwidth part configuration for reduced capability devices

Methods, systems, and devices for wireless communications are described. For example, a UE may determine a power control adjustment based on sidelink messages received from other UEs. The UE may transmit, to the other UEs, an indication of the power control adjustment to the other UEs. The other UEs may transmit additional sidelink messages in accordance with the power control adjustment, such that power levels of the additional sidelink message satisfy a threshold. A base station may indicate a power control adjustment to one or more UEs. For example, the base station may receive power control information associated with sidelink communications between a set of UEs. The base station may transmit an indication of a power adjustment parameter for a transmit power level for sidelink messages transmitted between two UEs of the set. The value of the power adjustment parameter may be based on the received power control information.
