Abstract: A wireless communication method includes determining a length of a ZC sequence based on a resource block quantity or a subcarrier quantity corresponding to a system bandwidth and determining a reference signal sequence included in an uplink reference signal based on the length of the ZC sequence and a resource block quantity or a subcarrier quantity corresponding to an allocated user bandwidth that is a part of the system bandwidth. When different communications devices use the same system bandwidth for communication, reference signal sequences used by the different communications devices correspond to the same ZC sequence length. The ZC sequence length is exclusively designed for a resource block quantity or a carrier quantity of the system bandwidth. Generation of the reference signal sequences is related to mapped locations of the reference signal sequences. Therefore, reference signal sequences used by different communications devices have a relatively high cross correlation.

Abstract: A communication method and apparatus includes a terminal that receives first control information from a network device. The first control information includes a first field. The first field indicates single-carrier scheduling or the multi-carrier scheduling. When the first field indicates the single-carrier scheduling, the terminal communicates with the network device on one scheduled carrier. Alternatively, when the first field indicates the multi-carrier scheduling, the terminal communicates with the network device on a plurality of scheduled carriers. According to the method and the apparatus in this application, the first field in the first control information may explicitly or implicitly indicate the single-carrier scheduling or the multi-carrier scheduling, and the network device does not need to additionally send a notification message, thereby reducing air interface overheads.
