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.

Decoding of physical downlink control channels ending at same symbol or different symbols

A user equipment for wireless communication is provided. The UE operates within an active bandwidth part (BWP) of a component carrier, wherein the active BWP is a portion of a total bandwidth of the component carrier, determines a configuration for a dynamic channel state information (CSI) measurement gap, the dynamic CSI measurement gap including channel state information (CSI) measurement resources having a frequency domain occupation within the total bandwidth of the component carrier and outside of the active BWP, measures the CSI measurement resources included in the dynamic CSI measurement gap, and transmits a CSI report based on the measured CSI measurement resources.

Dynamic channel state information (CSI) measurement gap for bandwidth limited low complexity user equipments

Methods, systems, and devices for wireless communications are described. 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.

Power control techniques for sidelink communications

Certain aspects of the present disclosure provide techniques for cross-carrier feedback.

Cross carrier feedback

Aspects of the disclosure relate to maintaining, defining, configuring and implementing a coverage enhancement mode defined for radio access network. A base station may maintain parameters that define multiple coverage enhancement modes in a lookup table and may select a first coverage enhancement mode from the two or more coverage enhancement modes for use with a first user equipment to accommodate use of one or more carrier frequencies, time or frequency duplexing mode, cell size, capabilities of the first user equipment or a channel measurements report of the first user equipment, and schedule a set of control and data channels to be used for communicating with the first user equipment using a first transmission scheme defined by first parameters associated with the first coverage enhancement mode. The set of control and data channels may include uplink control and data channels and downlink control and data channels.

Multi-mode configuration for coverage enhancements

Certain aspects of the present disclosure provide techniques for a physical downlink control channel (PDCCH) ordered random access channel (RACH) procedure. The RACH procedure may be associated with a cell-defining synchronization signal block (SSB) or non-cell-defining SSB. A method for wireless communications by a user equipment (UE) includes transmitting an indication of one or more capabilities of the UE, receiving a PDCCH that orders the UE to perform a RACH procedure on an uplink carrier based on the one or more capabilities of the UE, determining a minimum gap between a last symbol of the PDCCH and a first symbol of a RACH message, wherein the minimum gap includes a half-duplex (HD) switching delay, and performing the RACH procedure on the uplink carrier when a gap between the last symbol of the PDCCH and the first symbol of the RACH message is equal to or larger than the minimum gap.

PDCCH ordered random access channel procedure for reduced capability user equipment

Techniques for reconfigurable intelligent surface (RIS)-assisted calibration for timing errors in wireless nodes may comprise obtaining a set of wireless reference signal measurements comprising: first, second, third, and fourth measurements of reference signals traveling between the mobile device, a first wireless node, and a second wireless node, wherein a portion of the reference signals are reflected by the RIS while traveling between the mobile device and the first or second wireless node. A differential value comprising a difference between the third measurement and the fourth measurement is also obtained. Determining a position estimate of the mobile device may then be performed, based at least in part on the set of wireless reference signal measurements, the differential value, and a respective location of each of the first wireless node, the second wireless node, and the RIS.

Reconfigurable intelligent surface (RIS)-assisted timing error calibration for mobile device positioning

A user equipment (UE) receives information for a physical downlink control channel (PDCCH) or a physical downlink shared channel (PDSCH), where the PDCCH/PDSCH are broadcast or group-cast from a base station and have a quasi co-location relationship with a synchronization signal/PBCH (SSB) block or a channel state information reference signal (CSI-RS) beam. The UE monitors for or receives the PDCCH/PDSCH based on at least one of a search space (SS) set configuration enhancement for the PDCCH, a demodulation reference signal (DM-RS) resource configuration enhancement for the PDCCH or the PDSCH, or a scrambling identifier set enhancement for payload bits of the PDCCH or the PDSCH, which support the spatial division multiplexing (SDM) with another PDCCH/PDSCH that are broadcast or group-cast from the same base station and have the quasi co-location relationship with a different SSB block or a different CSI-RS beam.

Spatial division multiplexing for reduced capability wireless devices

Certain aspects of the present disclosure provide techniques for controlling access and use of network resources and services by user equipment based on user equipment capabilities. In one aspect, a method for wireless communication by a network entity, includes: receiving, from a user equipment, a request to connect to a network, the request comprising a user equipment identifier and a reduced capability indication; determining a validity of the reduced capability indication based on at least one of: subscription data associated with the user equipment; or one or more capabilities associated with the user equipment; and making a connection decision based on the validity of the reduced capability indication.

Restricted access and use control for user equipment with reduced capabilities

Methods, systems, and devices for wireless communications are described. A synchronization signal block (SSB) may be dynamically scheduled within an operating bandwidth of a user equipment (UE), where the operating bandwidth of the UE is outside of a frequency resource in which a cell defining SSB (CD-SSB) is scheduled. For example, a UE may operate in a reduced capability mode or an enhanced reduced capability mode where the UE may operate in a narrower bandwidth than the serving cell bandwidth. Control signaling may dynamically configure an SSB for the UE within the operating bandwidth of the UE. The UE may monitor for the non-cell defining SSB (NCD-SSB) and skip monitoring for the CD-SSB based on the dynamically configured NCD-SSB. For example, a reduced capability UE or an enhanced reduced capability UE may monitor for the NCD-SSB without performing RF retuning between receiving the control signaling and monitoring for the NCD-SSB.

Techniques for configuring bandwidth parts and synchronization signal blocks

Various aspects of the present disclosure generally relate to multi-slot transmission time interval based channel state information (CSI) and uplink shared channel (UL-SCH) multiplexing. In some aspects, a user equipment (UE) may receive a downlink control information (DCI) message and determine, based at least in part on the DCI message, a schedule for multiplexing UL-SCH data and one or more components of uplink control information (UCI) in a plurality of slots on a physical uplink shared channel (PUSCH). The components may include a CSI report for a plurality of transmission reception points. The UE may multiplex the UL-SCH data and the one or more components into the plurality of slots based at least in part on the schedule. Numerous other aspects are provided.

Multi-slot transmission time interval based channel state information and uplink shared channel multiplexing

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, an indication that a cell associated with the base station does not support reduced capability UEs, wherein the UE is capable of operating in a first mode that is associated with reduced capability UEs and a second mode that is not associated with reduced capability UEs. The UE may communicate, in the second mode, with the base station to establish a connection with the cell based at least in part on at least one of: the UE supporting one or more capabilities associated with connecting with the cell, or no cells that support reduced capability UEs being available. Numerous other aspects are described.
