A beam measurement and reporting method, and a computer readable storage medium are provided. The method includes: configuring measurement parameters and report parameters for one or more target beam groups, wherein, the measurement parameters include reference signal resources, reference signal resources corresponding to different target beam groups are different, reference signal resources for beams of at least two TRPs in the one or more target beam groups are same; transmitting the measurement parameters and the report parameters to a mobile terminal; controlling beams of the one or more target beam groups to transmit reference signals on reference signal resources corresponding to the beams, wherein the reference signals are used by the mobile terminal to perform beam measurement; receiving a measurement report including measurement results reported by the mobile terminal based on the report parameters.

A user equipment (UE) includes a receiver that receives a Reference Signal (RS) from a base station (BS), and a transmitter that transmits, to the BS, only precoding-related information used for precoding in the BS in response to the RS. The precoding-related information is at least one of a RS Resource Indicator (RRI) that identifies a radio resource used for RS BS transmission, a Precoding Matrix Indicator (PMI), a Rank indicator (RI), and a Reference Signal Received Power (RSRP). The transmitter only periodically transmits the only precoding-related information. The receiver receives a signal precoded using the precoding-related information by the BS.

A wireless device for determining wireless channel metrics and/or cell quality when accessing wireless resources. For example, the wireless device may use the determined channel metrics and/or cell quality when performing cell selection and/or cell reselection procedures. The wireless device may use the determined channel metrics and/or cell quality to trigger and report cell or frequency measurements in one or more cells neighboring the device's serving cell. The wireless device may use (e.g., further use) the determined channel metrics and/or cell quality to select a beam or sub-band for initial access to a cell. The wireless device may be employed within a wireless communications network that utilizes unlicensed wireless spectrum.
