1. A method for an uplink resource request, the method comprising:
sending, by a terminal side device, K uplink resource requests on K uplink channel resources, respectively, wherein the K uplink resource requests do not overlap in time domain, and K is an integer greater than or equal to 2; and
receiving, by the terminal side device, resource allocation information from an access network side device, wherein the resource allocation information indicates an uplink resource,
wherein cyclic shifts of a code division multiplexing (CDM) sequence are used to send the K uplink resource requests on the K uplink channel resources, respectively;
wherein a kth cyclic shift of the CDM sequence is a cyclic shift αk used for a kth uplink resource request in the K uplink resource requests, wherein αk is determined based on a parameter Ik and Ik satisfies the following relationship:
Iidx=I0·(Ncs)0+I1·(Ncs)1+ . . . +Ik·(Ncs)m+ . . . +IK-1·(Ncs)K-1; and
wherein Ncs is a maximum quantity of possible values of the cyclic shift of the CDM sequence, the parameter Iidx is the parameter indicated in the higher layer signaling, and k is any integer from 0 to K−1.
