Provided herein are a method and an apparatus for interference measurement using a beam management reference signal (BM-RS). The disclosure provides an apparatus for a user equipment (UE), comprising circuitry configured to: decode one or more beam management reference signals broadcasted by a Transmission Reception Point (TRP) in a cell, wherein the one or more beam management reference signals are used by the TRP to perform beam management for respective one or more other UEs in the cell; and measure interference from the one or more other UEs in the cell based on the decoded one or more beam management reference signals. According to some embodiments, the overhead for the interference measurement can be reduced since it is not necessary to allocate a separate CSI-RS for the purpose of interference measurement.

A method that comprises identifying a group of user equipment (UEs) in a radio access network, where the group includes a transmitting UE and a plurality of receiving UEs. The method further comprises sending control information including probe signal parameters to the transmitting UE and to the receiving UEs. The method also comprises receiving, from the receiving UEs, performance metrics relating to receipt of a probe signal sent by the transmitting UE based on the probe signal parameters. The method may be implemented by a scheduler. As such, based on the feedback received, the scheduler may carry out more judicious pairing of UEs for uplink and downlink transmission, which may be particularly suitable when the UEs communicate in half-duplex fashion.

In accordance to embodiments, a base station may transmit to a first user equipment (UE) a downlink control information (DCI) message for uplink (UL) scheduling of a second UE. The DCI message may indicate resources for sending a UL message by the second UE to the base station such that the first UE can at least partially decode the UL message based on the information in the DCI message. The base station may receive the UL message from the second UE. The base station may send a downlink (DL) message to the first UE. The UL message and the DL message may overlap at least partially in time and frequency. If the DL UE cannot successfully decode the UL message, the base station may send a helper message for the UL message to help the DL to decode the UL message.

The present invention provides a base station device, a terminal device, and a communication method, where the terminal efficiently learns information of an interference signal and reduces interference in a reception process to make it possible to enhance throughput, enhance communication opportunity of each terminal device by feedback from the terminal, and the like. The base station device includes a transmission unit configured to transmit, to the terminal device, Multiuser Superposition Transmission (MUST) information used for canceling interference due to MUST. The MUST information includes multiple combinations of modulation schemes for the MUST, and a list of power ratios used for the MUST in each of the combinations of the modulation schemes.

A WAP for wireless communications on a selected orthogonal frequency division multiplexed (OFDM) communication channel of a wireless local area network (WLAN). The transceiver includes: antennas, transmit and receive chain components, a stream separation control circuit, and an Inter Carrier Interference (ICI) removal circuit. The receive chain components include: an equalizer component converting a received uplink communication packet from one or more of the associated stations at an input into discrete communication streams at an output thereof. The stream separation control circuit couples to the equalizer component to control the separation of the communication streams at the output of the equalizer component into groups, with each group comprising all of the communication streams transmitted by a corresponding one of the one or more associated stations. The ICI removal circuit couples to the stream separation control circuit to discretely remove ICI from each group of streams.

According to one embodiment, a wireless communication device includes a transmitter configured to transmit a first frame including first information required for uplink multi-user transmission without receiving a transmission request for the first information; and a receiver configured to receive a second frame.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a central unit (CU) may receive one or more cross-link interference (CLI) measurement reports that are based at least in part on one or more CLI measurements performed by one or more downstream nodes. The CU may transmit, and a distributed unit (DU) may receive, CLI measurement information based at least in part on the one or more CLI measurement reports. In some aspects, the DU may perform one or more CLI mitigation actions based at least in part on the CLI measurement information received from the CU. Numerous other aspects are provided.

Systems and techniques are provided for performing wireless communications at a user equipment (UE). For example, a process can include transmitting, from a UE based on a cross-link interference (CLI) cancellation capability of a receiver of the UE, a CLI cancellation capability indication. The process can include receiving, at the UE, a communications signal. In some implementations, the UE received the communications signal from a network entity. In some cases, receiving the communications signal from the network entity at least partially coincides with a transmission of an additional communications signal by an additional UE, wherein the additional UE is different from the UE.
