Information transmission method, user equipment, and base station

Abstract

The embodiment of the invention proposes an information transmission method, user equipment, and a base station. The method comprises the steps that the UE determines at least one candidate sequence of synchronous signals of an access cell and a plurality of candidate access resources of the access cell, wherein the each of the plurality of candidate access resources and the resource where the access cell is located have the corresponding position relation, and any one of the candidate sequences is corresponding to one of the candidate access resources; the UE detects the synchronous signals according to at least one candidate sequence; the UE determines the resource position of an actual access resource, corresponding to a detected actual sequence, in the access cell according to the position relation between each of the plurality of candidate access resources and the resource where the access cell is located and the corresponding relation between any one of the candidate sequences and the candidate access resources.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, to a method for information transmission, user equipment and a base station. Background technique [0002] In version 10 and earlier versions of the Long Term Evolution (LTE, Long Term Evolution) 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; the physical cell identity can also be obtained through the sequence combination of the detected PSS and SSS, and the cyclic prefix length can be determined through the time interval of 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 information, first read the physical broadcast channel (PBCH) to obtain the downlink system ban...

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.
