Abstract: Provided in embodiments of the present invention are a method and device for feeding back channel information, the method comprising: determining a set of channel measurement resources, the set of channel measurement resources comprising M channel measurement resources, where M is a positive integer; performing channel measurement on the M channel measurement resources; selecting N channel measurement resources from M channel measurement resources according to the channel measurement result, where N is a positive integer, and N≤M; feeding back indication information of the selected N channel measurement resources. The embodiments of the present invention may solve the problem in the related art that a technology for selection of channel measurement resources is incapable of effectively corresponding to multiple paths, leading to low system robustness and transmission efficiency. Thus, when selecting channel measurement resources, it is possible to correspond to multiple paths, thus improving the system robustness and transmission efficiency.

Abstract: Techniques are described for selecting root pairs for Zadoff-Chu sequences for random access preamble and for signaling one or more values associated with the root pair to a user equipment (UE) by a base station. The described root pair selection methods for two-root physical random access channel (PRACH) preamble can enable the peak differences received at the UE from different frequency offsets (FOs) to be disjointed even considering error in UE side. The selection techniques can improve the performance of PRACH FO and time offset (TO) estimation.
