A Transmission Reception Point (TRP 22) of a wireless communication network (10) operates with a Time Division Duplexing (TDD) configuration for downlink and uplink communications, and a network node (18) detects a trigger condition for adapting the TDD configuration, with the trigger condition at least including detection of an impairment condition arising from periodic fading on one or more of the radio links between the TRP and User Equipments (UEs 12). For example, the network node (18) determines that the impairment condition exists and satisfies one or more additional criteria, and, in response, adapts the TDD configuration of the TRP, to improve the responsiveness of Link Adaptation (LA) by the TRP (22). An advantageous recognition underlying responsive adaptation of the TDD configuration is that the TDD configuration of the TRP (22) influences the LA time constant or convergence time of the LA algorithm used by the TRP (22).

A method of measuring a received signal strength by a radio device in a radio access network, RAN, is provided. The radio device obtains a radio resource information indicative of a spatial domain of a radio resource for measuring the received signal strength. The spatial domain of the radio resource corresponds to a combination of antenna elements in the radio device according to a spatial domain filter. The radio device measures the received signal strength on the radio resource in the spatial domain according to the obtained radio resource information. The radio device transmits a report to the RAN, the report being indicative of the received signal strength. The received signal strength includes a received signal strength indicator, RSSI.

Provided are an array selection method, a terminal, a network device, and a storage medium. The method comprises: sending assistance information to a network device, wherein the assistance information comprises at least one of the following: identifier information of an optimal reference signal required for uplink transmission, and an array-based maximum power reduction (P-MPR) value corresponding to one or more arrays of a terminal when a maximum power exposure (MPE) event occurs; and receiving indication information sent by the network device on the basis of the assistance information, wherein the indication information is used for indicating an array used by the terminal for subsequent uplink transmission, or for indicating that the terminal performs new uplink beam scanning. The embodiments of the present application avoid the uplink coverage loss caused by an MPE issue.

This application discloses methods and apparatuses for radio frequency channel sharing. An example method includes sending, by a terminal, first user equipment (UE) capability information to a network side device after receiving UE capability enquiry signaling that is sent by the network side device for a first subscriber identity module (SIM) card. The example method further includes sending, by the terminal, second UE capability information to the network side device after receiving UE capability enquiry signaling that is sent by the network side device for a second SIM card, wherein radio frequency capability information in the first UE capability information is the same as radio frequency capability information in the second UE capability information.

Wireless communications systems and methods related to channel occupancy time (COT) sharing for sidelink communications in unlicensed bands are provided. A method for wireless communication by a first user equipment (UE) may include measuring a first reference signal received power (RSRP) of a physical sidelink feedback channel (PSFCH) transmission transmitted during a channel occupancy time (COT) initiated by a second UE and accessing a first slot of the COT based on the first RSRP.

A method for configuring a modulation and coding scheme (MCS) is performed by a terminal, and includes: determining an MCS table used by the terminal for part of channels during a random access procedure based on a designated scheme; wherein the designated scheme includes any one of: a scheme based on an indication message and a preconfigured rule.

According to some aspects, a wireless device may indicate to another device a receive configuration indicator (RCI) to indicate a receive spatial configuration of the wireless device. For example, a first device may configure the first device to receive, from a second device, a signal using a first receive spatial configuration of the first device that corresponds to a first transmit spatial configuration of the second device. The first device may further determine a RCI to indicate the first receive spatial configuration of the first device, and may transmit the RCI to the second device.

Precoders are provided for multi-panel uplink (UL) transmission. A codebook may support asymmetric multi-panel UL transmission or super UL transmission where NR and LTE transmissions may be provided through different antenna panels of a UE. Sounding reference signal (SRS) enhancement provides support for multi-panel transmission.

Disclosed are a relay method and device in a communication system. An operation method of a first communication node comprises the steps of: transmitting a reference signal to one or more candidate R nodes; receiving first feedback information including a minimum value of a first RSRP from a first candidate R node belonging to the one or more candidate R nodes; receiving second feedback information including a minimum value of a second RSRP from a second candidate R node belonging to the one or more candidate R nodes; comparing a first value based on the first feedback information with a second value based on the second feedback information; when the first value is greater than the second value, selecting the first candidate R node as an R node that is to perform a relaying operation; and communicating with a second communication node via the R node.

Configuring channel state information reference signal (CSI-RS) reporting at a network may include encoding a channel state information (CSI) reporting configuration communication for transmission to a user equipment (UE) that is in connected mode with both a first transmission and reception point (TRP) and a second TRP. The CSI reporting configuration may include a first group of CMR (Channel Measurement Resource) resources for the first TRP, and a second group of CMR resources for the second TRP. A CSI measurement communication received from the UE, may be measurements based on the CSI-RS reporting configuration communication. Based on the CSI measurement communication, one or more downlink data transmissions may be scheduled.
