摘要

A user equipment (UE) is provided. The UE includes higher layer circuitry configured to receive first information to configure a sidelink bandwidth part (BWP) and second information to configure one or more resource pools for sidelink transmission and/or reception. The UE further includes transmission circuitry configured to transmit a physical sidelink control channel (PSCCH) and a physical sidelink shared channel (PSSCH). The first information includes a configuration of numerologies for the PSCCH and PSSCH and the second information includes a configuration of one or more resource pools for the PSCCH and PSSCH within the sidelink BWP.

說(shuō)明書(shū)

For the uplink, the higher-layer parameter DirectCurrentLocation in the UplinkTxDirectCurrentBWP IE may indicate the location of the transmitter DC subcarrier in the uplink for each of the configured bandwidth parts, including whether the DC subcarrier location is offset by 7.5 kHz relative to the center of the indicated subcarrier or not. Values in the range 0-3299 represent the number of the DC subcarrier, the value 3300 indicates that the DC subcarrier is located outside the resource grid, and the value 3301 indicates that the position of the DC subcarrier in the uplink is undetermined.

    • Each element in the resource grid for antenna port p and subcarrier spacing configuration μ is called a resource element and is uniquely identified by (k,l)p,μ where k is the index in the frequency domain and 1 refers to the symbol position in the time domain relative to some reference point. Resource element (k,l)p,μ corresponds to a physical resource and the complex value ak,l(p,μ). When there is no risk for confusion, or no particular antenna port or subcarrier spacing is specified, the indices p and μ may be dropped, resulting in ak,l(p) or ak,l.
