1. A random access method, comprising:
- sending, by a first User Equipment (UE) in a UE group, a preamble to an evolved Node B (eNB) over a time-frequency resource, the time-frequency resource comprising a time domain resource and a frequency domain resource;
monitoring, by at least one of the first UE or a second UE in the UE group, a Random Access Response (RAR) corresponding to the preamble and sent by the eNB, wherein the first UE is at least one UE in the UE group, and the second UE is all or some UEs in the UE group; and
after monitoring, by at least one of the first UE or the second UE, the RAR corresponding to the preamble and sent by the eNB;
sending, by at least one of the first UE or the second UE, a message 3 according to a Uplink (UL) grant allocated thereto, wherein the message 3 comprises a number of UEs having random access requests in the UE group or a number of UEs contained in the UE group or a pre-set UE number.

Abstract
A random access method comprises: transmitting, by a firstuser equipment (UE) in a UE group, and according to a time-frequency resource, a preamble to an evolved node B (eNB); and monitoring, by a second UE in the UE group and/or the first UE, for a random access response (RAR) corresponding to the preamble transmitted by the eNB, wherein the first UE is at least one UE in the UE group, and the second UE is all or a part of the UEs in the UE group.
