Preferably, the user equipment determines that each repetition transmission in a transmission cycle in addition to first time is used Physical resource before, further includes:
The user equipment determines the signal in one transmission cycle according to the information that network side equipment configures First time transmit used in physical resource；Or
The user equipment will send each physical resource in resource pool and be determined as the signal in one transmission Physical resource used in first time transmission in period.
User equipment can be in conjunction with the transmission resource pool or reception for repeating to carry in transmission of configuration information and synchronizing channel Resource pool information determines the physical resource of association detection target UE signal.For example, repeating to transmit all physics used Resource is selected in transmission resource pool or reception resource pool.
User equipment carries out target UE signal according to the physical resource of the target UE signal detected Association detection.Specifically, user equipment can will be repeated several times transmit the signal that is detected on corresponding multiple physical resources into Row is demodulated again after merging.Merging demodulation can be after directly merging to the signal on different physical resources and demodulate, It is also possible to obtain the soft bit information of each signal after detecting unlike signal, then after soft bit information is merged Demodulation.
