Transmission method and device of signals for sequence modulation

Abstract

The embodiment of the invention discloses a transmission method of signals for sequence modulation, comprising the following steps: whether user equipment (UE) belongs to a first group of UE or a second group of UE is determined by UE according to first control information sent by a base station or own characteristics of the UE, wherein the sequence set jumping rule corresponding to the first group of UE is different from that corresponding to the second group of UE; sequence jumping parameters are acquired; signals for sequence modulation are generated according to the sequence jumping parameters and the sequence set jumping rules corresponding to the UE groups of the UE; and the signals for sequence modulation are sent to the base station. As the first group of UE and the second group of UE use different sequence set jumping rules to generate the signals for sequence modulation and send the signals to the base station, the intercell interference can be randomized, and the signal detection performance of the base station is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for transmitting a sequence-modulated signal. Background technique [0002] In the prior art, the user equipment (UE) sends a reference signal (RS, Reference Signal) to the base station, where the RS is generated by the UE through the sequence conversion of a certain sequence group, and the sequence grouping principle is usually to compare the cross-correlation Small sequences are classified into different groups, and UEs in different cells use sequences of different groups, so that the interference between cells will be relatively small. However, since the number of sequence groups is limited, the size of the low-interference area formed by cells allocated with different sequence groups is limited, and the cells outside each low-interference area must reuse these sequence groups, which leads to reuse There will be strong inter-cell interference between diff...

However, since the number of sequence groups is limited, the size of the low-interference area formed by cells allocated with different sequence groups is limited, and the cells outside each low-interference area must reuse these sequence groups, which leads to reuse There will be strong inter-cell interference between different cells in the same sequence group for a certain period of time, resulting in poor detection capabilities of the base stations corresponding to these cells to the signals sent by the UE
