Information transmission method, user equipment and base station

Abstract

The embodiment of the present invention proposes an information transmission method, user equipment and base station. The method includes: the UE determines at least one candidate sequence of the synchronization signal of the access cell and multiple candidate access resources of the access cell, wherein the Each candidate access resource in the plurality of candidate access resources has a corresponding positional relationship with the resource where the access cell is located, and any candidate sequence in the at least one candidate sequence corresponds to one of the plurality of candidate access resources; The UE detects the synchronization signal based on the at least one candidate sequence; the UE detects the synchronization signal based on the location relationship between each candidate access resource in the plurality of candidate access resources and the resource where the access cell is located and the location relationship between the at least one candidate access resource and the The corresponding relationship between any candidate sequence and the multiple candidate access resources is determined to determine the resource location of the actual access resource corresponding to the detected actual sequence in the access cell.

Description

Technical field [0001] The present invention relates to the field of communication, and more specifically, to a method, user equipment, and base station for information transmission. Background technique [0002] In the version 10 and previous versions of the Long Term Evolution (LTE) system, the process of UE accessing the LTE system is to first detect the PSS, and then detect the SSS through the time-domain position relationship between the two to achieve initial time-frequency synchronization , Including symbol, subframe and frame synchronization; it can also obtain the physical cell identity through the sequence combination of the detected PSS and SSS, and determine the cyclic prefix length through the time interval between PSS and SSS; then the CRS can be determined to measure the cell If the measurement result is good, you can continue to read the system message, first read the PBCH to obtain the downlink system bandwidth, CRS antenna port, system frame number, PHICH config...

Problems solved by technology

[0003] However, when the deployment of base stations, especially the deployment of micro base stations is relatively dense, in the synchronization system, the interference between the cells under the jurisdiction of each micro base station will be very serious, making it more difficult for the UE to read the common control channels of the above cells. Big can't even get
