    摘要: Example communication methods and apparatus are described. In one example method, a terminal device receives configuration information of a first control resource set, where the configuration information of the first control resource set comprises mapping manner information of the first control resource set. The terminal device determines, based on the mapping manner information, a mapping manner between a control channel element (CCE) and resource element groups (REGs) in the first control resource set, where a REG in the first control resource set occupies one symbol in time domain and one resource block (RB) in frequency domain, and REGs in the first control resource set are numbered in a time-first manner. The mapping manner information indicates that the mapping manner is interleaved mapping.

    摘要: The present disclosure provides a method including: determining, by a network device, a resource element group corresponding to a control channel, where the resource element group includes a first resource element for carrying downlink control information and a second resource element for carrying a reference signal, and the reference signal is used to demodulate the downlink control information carried by the resource element group; and sending the downlink control information by using the control channel, wherein resource elements comprised in the resource element group are distributed in all symbols of a time domain resource occupied by the control channel. This provides a possibility of supporting forward compatibility.

    摘要: Embodiments provide a channel sounding information feedback method, user equipment, and a base station. The method includes: determining, by UE, a first period used to periodically report channel sounding information; and periodically sending, by the UE based on received preset downlink control information DCI that is sent by a base station, the channel sounding information by using the first period as a sending period. System overheads can be reduced, a configuration response can be improved, and spectrum utilization of a system can be improved while periodic feedback of indication is reduced.

    摘要: Example resource allocation methods and apparatus are described to resolve a problem of resource congestion and collision occurring in a communications system when virtual resource blocks (VRBs) scheduled for different terminal devices are mapped to physical resource blocks (PRBs). In one example method, system bandwidth of the communications system is divided into a plurality of fixed interleaving regions. Therefore, a network device can indicate a type of a virtual resource unit in a form of a frequency domain range occupied by one interleaving region. Using the foregoing solution can enable the network device to set the type of the virtual resource unit more conveniently.

The base station determines configuration information of a PUCCH and configuration information of an SRS, and sends the configuration information of the PUCCH and the configuration information of the SRS to the UE in a cell. The UE determines, according to the configuration information of the PUCCH, a frequency-domain resource for transmitting the PUCCH, and determines, according to the configuration information of the SRS, a frequency-domain resource for transmitting the SRS. The base station receives, according to the configuration information of the PUCCH, a subcarrier that carries the PUCCH sent by the UE, and demodulates the subcarrier to obtain the PUCCH. The base station receives, according to the configuration information of the SRS, a subcarrier that carries the SRS sent by the UE, and demodulates the subcarrier to obtain the SRS.
