Abstract: Aspects of the disclosure provide techniques for wireless communication using sub-band full duplex (SBFD). A network entity can inform a user equipment (UE) on the allocation of communication resources for SBFD operations using sub-bands. The network entity can indicate sub-band allocation in symbols/slots configured for SBFD operations using various techniques. A UE can receive a SBFD configuration of one or more time slots, each time slot including a plurality of symbols. The SBFD configuration indicates that one or more of the plurality of symbols are capable of an SBFD operation using a first sub-band for downlink (DL) communication and a second sub-band for uplink (UL) communication. The UE can communicate with the network entity in the one or more symbols configured for the SBFD operation using at least one of the first sub-band for DL communication or the second sub-band for UL communication.

Abstract: A method of wireless communication at a user equipment (UE) and related apparatus are provided. In the method, the UE receives a resource allocation for a first set of resources in a first frequency band that is disjoint from a second frequency band in a sub-band full duplex (SBFD) slot, and communicates with a network node using the first set of resources in the first frequency band and a corresponding second set of resources in the second frequency band. The method improves the resource allocation efficiency for scheduling resources over multiple disjoint sub-bands.

Abstract: Aspects described herein relate to mitigating interference between network nodes operating in full duplex (FD). In some aspects, a victim network node can indicate, to an aggressor network node, a capability to cancel interference from the aggressor network node, receive one or more uplink signals from a device along with one or more downlink signals from the aggressor network node in a same time period, and cancel, based on the capability, the one or more downlink signals received from the aggressor network node from the one or more uplink signals received from the device. In other aspects, the victim network node can indicate certain uplink resources to the aggressor network node, which can avoid transmitting downlink communications over the indicated uplink resources.

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 measurement configuration indicating one or more punctured resources of a physical downlink shared channel (PDSCH) that can be used for measurements associated with estimating an interference plus noise covariance (INC) matrix at the UE. The UE may receive, from the network node, a reporting configuration indicating one or more INC matrices at the UE to be reported. The UE may transmit, to the network node, a report indicating the one or more INC matrices at the UE based at least in part on receiving the reporting configuration. Numerous other aspects are provided.

Abstract: Certain aspects relate to techniques for estimating and compensating for antenna array rotation of a wireless node. For example, the antenna array of the wireless node may rotate about one or more of an x-axis, a y-axis, and a z-axis, which may misalign the antenna array relative to another antenna array of another wireless node, causing degradation of communications between the two nodes. In some examples, the wireless node may obtain, from a first antenna array of the other wireless node via a second antenna array of the first wireless node, a first pilot signal and a second pilot signal via a first beam. In some examples, the first wireless node may perform a first alignment compensation based on a phase difference between the first pilot signal and the second pilot signal.

Abstract: Techniques and apparatus for adapting bandwidth operation for full duplex user equipments (UEs) are described. One technique involves a base station (BS) determining a plurality of resource bandwidths (BWs) within an active BWP that are available to be used for communications by one or more UEs. An indication of at least one resource BW of the plurality of resource BWs is signaled to a UE. Communications between the B S and the UE are performed on the at least one resource BW.

Abstract: Methods, systems, and devices for wireless communications are described. A base station that may include at least two transmission reception points (TRPs) next to a high speed train (HST) may transmit, to a user equipment (UE) on the HST, an indication of a quasi co-location (QCL) relationship indicating a relationship between a plurality of tracking reference signals (TRSs) and a demodulation reference signal (DMRS) of a data channel. The plurality of TRSs may include a first TRS and a second TRS. The UE may receive, from a first TRP, the first TRS associated with an occasion of the data channel, and receive, from a second TRP, the second TRS associated with the occasion of the data channel. The UE may perform, based on the indication of the QCL relationship, a channel estimation procedure for the data channel based on the DMRS, the received first TRS, and the received second TRS.
