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

Aspects described herein relate to receiving, by a base station, assistance information to facilitate configuring one or more parameters for communicating by a device with the base station, transmitting, by the base station, a signal that does not include the one or more parameters that are based on the assistance information, detecting, by the base station, a degraded feedback for the signal transmitted to the device, and transmitting, by the base station and based on detecting the degraded feedback, an assistance response signal including one or more parameters based on the assistance information.

Techniques for modifying parameters based on assistance information in wireless communications

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

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

Bandwidth part (BWP) switching may benefit a wireless communications system. Such BWP switching may include indication of one or more timing parameters used for time domain resource allocation. For example, the timing parameters may be indicated based on an index to a look-up table (e.g., a bit field in a control transmission). In some cases, one or more tables may be configured for a given BWP, and different tables may contain a different number of rows. The size of the bit field indexing the table may in turn depend on the number of rows. When switching from a first BWP to a second BWP, the size of the bit field may be based on the table of the first BWP, but the bit field may index the table of the second BWP. Techniques supporting improved timing parameter management during BWP switching are discussed herein.

Timing parameter management for bandwidth part switching

Aspects of the disclosure relate to wireless communications utilizing dormancy indications for secondary cells (SCells) and determining application delay times based on the dormancy indications.

Secondary cell dormancy indication and application delay

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

Methods, systems, and devices for wireless communications are described. In some cases, a user equipment (UE) may transmit, to a base station, a report indicating a capability of the UE to support symbol level quantization, slot level quantization, or both. The UE may identify that the UE is to utilize the slot level quantization. For instance, the UE may receive control signaling indicating that the UE is to utilize slot level quantization and may perform the identifying based on receiving the control signaling. The UE may receive a first transmission via a first channel and may communicate, responsive to receiving the first transmission, a second transmission via a second channel at a quantized start timing determined in accordance with the slot level quantization.

User equipment timeline quantization

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

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

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a capability report to a base station indicating a triggering offset. The base station may configure the UE with one or more channel state information (CSI) measurement resources and send downlink control information (DCI) that triggers an aperiodic CSI report for some of the CSI measurement resources. The UE may report CSI by measuring the CSI resources after the triggering offset. In some cases, CSI reporting related to the different codebook types (e. g., Type I, Type II) may be modified, where after identifying a type of codebook and determining which type of codebook to process (e. g., based on a number of CSI processing units), the UE may identify a priority associated with different CSI reports. The UE may be configured with various parameters that relax or modify the processing of Type II CSI reports.

Techniques for simplifying channel state information feedback

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) included in a first category of UEs may receive a configuration that configures a paging early indication (PEI) in a first initial downlink bandwidth part associated with the first category of UEs, and may monitor for a PEI in the first initial downlink bandwidth part based at least in part on the configuration. In some aspects, the UE may receive a configuration that configures a PEI in a second initial downlink bandwidth part associated with a second category of UEs, and may monitor for a PEI in the second initial downlink bandwidth part based at least in part on the configuration. Numerous other aspects are described.

The UE may transmit, on a sidelink channel, a sidelink synchronization signal in a transmission period that includes a plurality of synchronization signal occasions based at least in part on the out-of-coverage scenario. In some aspects, the UE may transmit the sidelink synchronization signal according to a reduced duty cycle that causes the sidelink synchronization signal to be transmitted during fewer than all of the plurality of synchronization signal occasions. Numerous other aspects are provided.
