Abstract: Methods, apparatuses, and computer readable medium for beam switch are provided. An example method may include receiving, from a base station, at least one of a scheduling request (SR) configuration to indicate a request for a beam switch or a physical random access channel (PRACH) configuration representing a set of PRACH resources to indicate the request for the beam switch. The example method may further include transmitting, to the base station, a PRACH or an SR in a physical uplink control channel (PUCCH) that indicates the request for the beam switch for one or more downlink (DL) or uplink (UL) channels.

Abstract: A method for wireless communication at a first network entity and related apparatus are provided. In the method, the first network entity communicates, with a second network entity, information indicative of a guard interval length. The information indicative of the guard interval length is based on transmission information. The first network entity further communicates, with the second network entity, a transmission including one or more symbols. Each symbol of the one or more symbols includes a particular guard interval based on the information indicative of the guard interval length. The method enables the GI length to be flexibly configured depending on various waveforms or channel parameters and characteristics of the transmission. The method enables transmission resources to be fully utilized according to actual operating conditions. Thus, it improves the efficiency and flexibility of wireless communication.

Abstract: Methods, apparatuses, and computer readable medium for beam switch are provided. An example method may include transmitting, to a base station, a channel state information (CSI) report associated with a beam switch. The example method may further include performing the beam switch based on the CSI report and an absence, for a period of time after transmission of the CSI report, of a downlink control information (DCI) including a transmission configuration indicator (TCI) indication.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node, a configuration associated with cell scheduling. The UE may perform and based at least in part on the configuration and for a cell scheduling of a second cell, a physical downlink control channel (PDCCH) monitoring on a first cell or on the second cell based at least in part on one or more of a discontinuous reception (DRX) state of a first DRX group associated with the first cell or a DRX state of a second DRX group associated with the second cell. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, from a first network node associated with the first UE, a cross-link interference (CLI) configuration. The first UE may transmit, to a second UE, an inter-UE CLI measurement reference signal based at least in part on the CLI configuration, a measurement associated with the inter-UE CLI measurement reference signal being signaled to the first network node. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine an association between multiple phase tracking reference signal (PTRS) ports and multiple codewords that are to be used for an uplink communication that uses multiple antenna port groups, and transmit the uplink communication using the multiple codewords based at least in part on the association. Numerous other aspects are provided.

Abstract: Wireless communications systems and methods related to communicating control information are provided. A method of wireless communication performed by a user equipment (UE) may include performing a clear channel assessment (CCA), transmitting, to a first UE based on the CCA being successful, a first transport block (TB) via a first sub-PSSCH associated with a first sub-slot, and transmitting, to at least one of the first UE or a second UE, a second TB via a PSSCH associated with a slot.

Abstract: A UE may identify one or more fractional bands in relation to a bandwidth associated with FD communication. Each fractional band in the one or more fractional bands may be a fraction of the bandwidth. The UE may sample at least one signal at the one or more fractional bands. The UE may estimate one or more SIC coefficients based on the at least one signal. The UE may perform SIC for the bandwidth associated with the FD communication based on the estimated one or more SIC coefficients. In one configuration, the at least one signal may be sampled with a sampling rate less than a threshold. In one configuration, the at least one signal may be sampled using an auxiliary hardware path including an auxiliary ADC. In one configuration, the sampling the at least one signal may be associated with decimation or rotation.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for reallocating padded acknowledgment resources. A user equipment (UE) may be configured to use resources allocated for acknowledgment feedback that may be otherwise associated with padded feedback bits for additional reporting bits. For example, if acknowledgment feedback includes at least one positive acknowledgment (ACK) bit, the UE may replace (for example, reallocate) one or more padded feedback bits with additional reporting bits. If the UE is unable to receive an instance of downlink control information (DCI), or if the UE unsuccessfully receives or decodes each scheduling unit scheduled by an instance of DCI, the UE may maintain padded feedback bits acknowledgment feedback. In various implementations, additional reporting bits may indicate one or more of a power headroom (PH) value, a modulation and coding scheme (MCS), a preferred beam configuration, or a maximum permissible exposure (MPE) value.
