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

Wireless communications systems and methods related to communicating ACK/NACK feedbacks for multi-user and unicast physical down-link shared channel (PDSCH) communications are provided. A UE may receive a multi-user PDSCH communication including a first transport block (TB) for the UE and may receive a unicast PDSCH communication including a second TB for the UE. The UE may determine a hybrid automatic repeat request (HARQ) codebook for the first TB associated with the multi-user PDSCH communication and the second TB associated with the unicast PDSCH communication. The UE may transmit a first acknowledgement/negative-acknowledgment (ACK/NACK) feedback for the first TB and a second ACK/NACK feedback for the second TB based on the determined HARQ codebook.

Dynamic hybrid automatic repeat request (HARQ) codebook for multi-user packet (MUP) and/or unicast communications

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

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling, such as a control message or radio resource control (RRC) signaling, from a base station indicating a time interval over which to determine available power headroom relative to a transmission power threshold. The UE may calculate the available power headroom relative to the transmission power threshold as a function of UE transmission power during the time interval. The UE may transmit a power headroom report in an uplink transmission to the base station, the power headroom report indicating the calculated available power headroom. The base station may schedule one or more uplink messages at the UE according to the available power headroom.

Power headroom reporting for dynamic power aggregation

Techniques are described herein for performing channel estimation for both uplink and downlink channels. Additional reference signals may be allocated or assigned to various resource elements (REs) of a transmission time interval (TTI). The receiving device (e.g., a base station or a user equipment (UE)) may be configured to use the additional reference signals during channel estimation. The use of additional reference signals may improve the accuracy of the channel estimations. In downlink communications, a base station may allocate one or more channel state information reference signals (CSI-RSs) to a port of a UE. In uplink communications, a UE may transmit several sounding reference signals (SRSs) in a group.

Techniques for channel estimation

Certain aspects of the present disclosure provide techniques for using subband precoding for uplink transmissions. In some cases, a UE may receive, from a network entity, information indicating one or more of sounding reference signal (SRS) ports selected by the network entity and associated linear combination coefficients, determine subband precoding based at least in part on the selected SRS ports and linear combination coefficient, and transmit a physical uplink shared channel (PUSCH) with the subband precoding.

Uplink subband precoding via sounding reference signals precoded by frequency domain bases

Certain aspects of the present disclosure provide techniques for performing wireless communications. In one aspect, a method of wireless communications by a user equipment (UE) includes performing wireless communications with a network entity using an inter-band aggregated carrier group, wherein: the inter-band aggregated carrier group comprises at least a first carrier on a first band and a second carrier on a second band, the first carrier comprises a synchronization signal block, and the second carrier does not comprise any synchronization signal block.

Carrier group signaling in inter-band carrier aggregation

Certain aspects of the present disclosure provide techniques for a multi-slot sounding reference signal (SRS) resource. A method that may be performed by a user equipment (UE) includes receiving a configuration of an SRS resource, wherein the SRS resource comprises a set of symbols for transmission of SRS across a plurality of slots, and transmitting the SRS using the set of symbols across the plurality of slots to a base station.

Multi-slot sounding reference signal (SRS) resource

A configuration to allow for the transmission of system information on different beams, where different transmission parameters may be utilized for different beams. The apparatus transmits system information on a first beam. The apparatus transmits the system information on a second beam. The system information is transmitted using different parameters for the first beam and the second beam or comprises different system information content for the first beam and the second beam.

Beam specific RMSI transmission

Certain aspects of the present disclosure provide techniques for guard period configuration between subband full duplex and half duplex symbols and slots. An example method that may be performed at a user equipment (UE) includes obtaining an indication of a guard period during which a cell in which the UE is communicating will switch between subband full duplex (SBFD) communications and half duplex (HD) communications; and performing one or more actions during the guard period, in accordance with the indication.

Guard period configuration between subband full duplex and half duplex symbols and slots

Certain aspects of the present disclosure provide techniques for selecting an antenna configuration for transmitting in a wireless communication network. An example technique may include determining that a front guard period is not scheduled between a scheduled uplink transmission and a scheduled sounding reference signal (SRS) transmission, and based on the determination, transmitting the scheduled SRS transmission using a first antenna configuration after transmitting the scheduled uplink transmission using the first antenna configuration.

Guard period optimization for multi-antenna user equipments

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a status of a repetition procedure associated with a radio resource control (RRC) connection request message of a four-step random access channel (RACH) procedure. The UE may invoke an activity state of an RRC connection setup message monitoring procedure based at least in part on the status of the repetition procedure. Numerous other aspects are described.

Invoking an activity state of a radio resource control connection setup message monitoring procedure

Aspects of the present disclosure provide techniques for channel state information (CSI) reporting in multiple transmitter receiver point (mTRP) scenarios.

Methods for PMI, RI and port indexing of CSI for multiple transmitter receiver points

This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for determining numbers of BDs and CCEs for cross-carrier scheduling from a SCell to a PCell/PSCell. A UE may concurrently monitor, on different component carriers, a first PDCCH and a second PDCCH having different SCSs. The PDCCHs may each be configured to schedule PDSCH or PUSCH on a same component carrier of the different component carriers. Each of the PDCCHs may be associated with a respective number of PDCCH candidates or a respective number of non-overlapped CCEs, the respective numbers further associated with respective maximum numbers based on the different SCSs. A first sum of the respective number of PDCCH candidates or a second sum of the non-overlapped CCEs may be less than or equal to N times the lower of the respective maximum numbers.

Number of BD and CCE for cross-carrier scheduling from an S-Cell to a P-Cell

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to monitor search spaces on a primary cell and an secondary cell in a carrier aggregation configuration. The UE may monitor the search spaces for control information according to a shared search space monitoring configuration. Based on the shared search space monitoring configuration, the UE may identify that the secondary cell is a scheduling cell and the primary cell is a scheduled cell (e.g., cross-carrier scheduling). The UE may monitor control channel candidates of search spaces on the primary cell and on the secondary cell for downlink control information messages scheduling data transmissions with the primary cell. In some examples, the cross-carrier scheduled communications may be configured according to a scheduling configuration, which may include one or more scheduling constraints.
