Abstract: Wireless communications systems, apparatuses, and methods are provided. A method of wireless communication performed by a user equipment (UE) includes receiving, from a network unit, a first configuration indicating time location and frequency location for a network side subband full duplex (SBFD) mode of operation, wherein the time location indicates at least one SBFD symbol or slot (SBFD symbol/slot) format and the frequency location indicates a plurality of downlink and uplink subbands or a plurality of uplink subbands and guard bands and receiving, from the network unit, a second configuration indicating a change from the at least one SBFD symbol/slot format to a different SBFD symbol/slot format.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a message indicating one or more communication patterns from a base station. The one or more communication patterns may indicate to the UE to adjust one or more parameters for transmitting an uplink communication during a set of time resources, a set of beams, a set of ports, or any combination thereof. During the resources indicated in the one or more communication patterns, the base station may estimate a cross link interference channel between the base station and a second base station. The one or more communication patterns may indicate a hopping pattern for each subband of a bandwidth part. The base station may configure the UE with a timing advance based on the message.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select a set of radio link monitoring (RLM) reference signals according to a rule for selecting the set of RLM reference signals from among RLM reference signals that are quasi-colocated (QCLed) with active transmission control indicator (TCI) states for physical downlink control channel (PDCCH) communications in one or more control resource sets (CORESETs). The one or more CORESETs may include at least one CORESET with at least two active TCI states. The UE may monitor for the set of RLM reference signals. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may transmit, and a user equipment (UE) may receive, a sounding reference signal (SRS) configuration that indicates a reference group among multiple antenna groups of an antenna array associated with the UE. The UE may transmit an SRS using one or more antennas in the reference group. The UE may transmit, to the base station, a correlation report that indicates an inter-group correlation between the multiple antenna groups associated with the UE. The base station may estimate a channel matrix for the multiple antenna groups based at least in part on the inter-group correlation and measurements of the SRS that is transmitted using the one or more antennas in the reference group. 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: MAC-CE based dynamic MCS tables switching is introduced to support addition of higher modulation orders and new constellation types. First, a UE receives a RRC configuration indicating a plurality of MCS tables. Next, the UE receives a MAC CE activating a MCS table among the plurality of MCS tables. Doing so allows MCS tables to be dynamically switched via a MAC-CE based activation/reactivation adaptive to current signal to noise (SNR)/spectral efficiency (SPEF) experienced in a downlink and uplink. Finally, the UE communicates data with a base station using a MCS in the activated MCS table.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a communication indicating, via a resource indicator value (MV) or a bitmap, a frequency domain resource allocation (FDRA) for at least one slot. The UE may identify, using the MV or the bitmap, one or more first allocated resource block groups (RBGs) of a first slot of the at least one slot, wherein a size of each RBG of the one or more first allocated RBGs is based at least in part on whether the first slot is a sub-band full duplex (SBFD) slot. Numerous other aspects are provided.
