Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a UE determines a transmission power configuration for an uplink transmission on a bandwidth multiple sub-bands associated with different transmission power levels. The UE transmits, to a network component, a PHR that indicates a sub-band headroom value for each sub-band. The network component receives the PHR and performs a power control function associated with the UE based at least in part upon the PHR (e.g., per sub-band).

Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for grouping common DCI for CLI measurement and reporting. In a first aspect, a UE may receive DCI that is common to a group of UEs that includes the UE. The DCI may be configured to trigger at least one of an SRS transmission or a CLI measurement. The UE may transmit the SRS transmission and/or report the CLI measurement based on the DCI that is common to the group of UEs. In a second aspect, a base station may transmit at least one DCI that is common to the group of UEs to trigger the at least one of the SRS transmission or the CLI report for the group of UEs. The base station may receive the CLI report from at least a subset of UEs in the group of UEs.

Abstract: In wireless communication systems using a subband full duplex carrier, a single slot may include one or more uplink (UL) portions and/or one or more downlink (DL) portions. In a case where a scheduler operating in a 3GPP New Radio (NR) network utilizes a Type 0 or Type 1 resource allocation, part of the DL allocation may fall within the UL portion of the carrier designated by the slot format, or vice versa. User equipment (a UE) may perform a logical operation that identifies, as a usable downlink resource allocation, a set of resource blocks belonging to both a given UL/DL resource allocation and a set of resources designated for UL/DL transmission in the slot format.

Abstract: Aspects relate to time-interleaving of code block groups (CBGs) of a transport block. Some deployments can include configuring a downlink transmission to a scheduled entity that overlaps in time with an uplink transmission from the scheduled entity when the scheduled entity is operating in a full-duplex mode. CBGs may be time-interleaved to accommodate and/or mitigate interference between downlink and uplink transmissions. The modulation and coding scheme (MCS) of the transport block can further be adjusted to accommodate and/or mitigate interference between the downlink and uplink transmissions. Techniques discussed herein can be used at various nodes, components, and/or devices in a wireless network (e.g., UEs, BSs, CUs, RUs, DUs, etc.). Other aspects, features, and embodiments are also claimed and described.

Abstract: Methods related to wireless communication systems and transmission and/or reception of synchronization signal block (SSB) transmissions (e.g., in full-duplex slots) are provided. For example, a wireless communication device receives a synchronization signal block (SSB) transmission schedule. The SSB transmission schedule is at least partially overlapping with an uplink (UL) frequency portion of a full-duplex slot. The wireless communication device receives a first portion of a SSB in a downlink (DL) frequency portion of the full-duplex slot; and receiving a second portion of the SSB in the UL frequency portion of the full-duplex slot based on the SSB being scheduled in the full-duplex slot and at least partially overlapping with the UL frequency portion of the full-duplex slot. Other features are also claimed and described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink control information (DCI) that includes an indication of a null resource element pattern. The null resource element pattern may be indicated in the DCI using: a value of an antenna port field that also indicates one or more demodulation reference signal (DMRS) ports for the UE and a number of DMRS code-division multiplexing groups without data, or one or more zero power downlink reference signals. The UE may perform one or more demodulation interference measurements based at least in part on the null resource element pattern. The UE may demodulate a downlink communication based at least in part on performing the one or more demodulation interference measurements. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for fast adaptation of transmission properties of sounding reference signal (SRS) resource sets. A method that may be performed by a user equipment (UE) includes receiving sounding reference signal (SRS) configuration information, configuring the UE with one or more SRS resource sets, wherein each of the one or more SRS resource sets comprises one or more SRS resources; receiving signaling comprising a field indicating which of the one or more SRS resources in the one or more SRS resource sets are active and which of the one or more SRS resources in the one or more SRS resources sets are inactive; and transmitting one or more SRSs using only the one or more SRS resources that are active.

Abstract: Certain aspects of the present disclosure provide techniques for channel state information measurement adaptation to maximum multiple-input multiple-output layers. A method that may be performed by a user equipment (UE) includes receiving a first channel state information (CSI) report configuration including one or more first CSI reference signal (CSI-RS) resources, wherein each first CSI-RS resource comprises a first resource set; determining, based on an indication of a maximum number of multiple-input multiple-output (MIMO) layers that the UE is expected to receive, a first resource subset on which to report first CSI; and reporting the first CSI to a base station (BS), wherein the first CSI is based on the determined first resource subset.
