The present disclosure discloses a method for identifying a wireless AP performed at a server. The method includes: obtaining network connection information of terminal devices; for each terminal device, determining a rank for each respective wireless AP to which the terminal device connects by: analyzing corresponding network connection information to determine a first number of times of connections between the terminal device and the wireless AP; analyzing corresponding network connection information to determine a second number of times of connections between the wireless AP and each terminal device connecting to the wireless AP; and determining the rank for the wireless AP based on a weighted average of the first number of times of connections and the second number of times of connections; and returning identifier information of wireless APs as a first-type wireless AP to which the terminal device connects and their corresponding ranks to the terminal device.

A beam failure recovery method and device are provided. The method includes: after a beam failure recovery event is triggered, user equipment (UE) monitoring a physical downlink control channel (PDCCH) scrambled with a cell radio network temporary identifier (C-RNTI) in a first control channel resource set (CORESET) for beam failure recovery, and monitoring a PDCCH scrambled with a C-RNTI in a second CORESET.

Provided are a resource transmission method, a terminal device, and a network device, which are applied to the technical field of communications and can reduce or prevent transmission interference and waste of transmission resources. The embodiment of the present invention involves: according to first information, determining not to perform listen before talk (LBT) detection and/or resource transmission, or determining to perform LBT detection and/or resource transmission for a first resource, wherein the first information is used for indicating at least one of the following: a second resource, performing LBT detection and/or resource transmission, and not performing LBT detection and/or resource transmission.

For CSI reporting mechanisms, a user equipment (UE) includes a transceiver and a processor operably connected to the transceiver. The transceiver is configured to receive channel state information (CSI) process configuration information including at least one beamformed type associated with a plurality of non-zero-power (NZP) CSI reference signal (CSI-RS) resource configurations and receive a CSI-RS resource index (CRI) reporting configuration. The processor is configured to calculate, in response to receipt of the configuration information, a CRI and a channel quality indicator (CQI). The transceiver is further configured to report the CRI and the CQI by transmitting the CRI and the CQI on an uplink channel.

The present disclosure relates to a user device, a base station, a method for data transmission/reception by a user device, and a method for data reception/transmission by a base station. The user device comprises circuitry which, in operation, receives a parameter defining a rule for assigning to ports respective resources for carrying reference signals, generates, based on a mapping known to the user device and the base station, a set of layer-to-port mapping combinations, and receives, from the base station, control information indicating one of the set of layer-to-port mapping combinations which is to be applied for data transmission and/or reception.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine resource selection priority levels associated with available resources for sidelink signaling in an unlicensed radio frequency spectrum band, the resources selection priority levels may be determined based on resource reservation information of the available resources, a time domain location of the available resources, or both. For example, a first resource of the available resources may be associated with a higher priority than a second resource of the available resources in resource selection. The UE may select one or more resources for the sidelink signaling from the available resources based on the resource selection priority levels associated with the available resources. The UE may transmit the sidelink signaling on the unlicensed radio frequency spectrum band using the one or more selected resources.
