METHOD FOR SENDING PILOT FREQUENCY, STATION AND ACCESS STATION

Title:

METHOD FOR SENDING PILOT FREQUENCY, STATION AND ACCESS STATION

Document Type and Number:

WIPO Patent Application WO/2016/090529

Kind Code:

A1

Abstract:

Provided are a method for sending a pilot frequency, a station and an access station. The method comprises the following steps: a station receiving a pilot frequency sending notification from an access point, wherein the pilot frequency sending notification comprises a pilot frequency sending rule of the station and a pilot frequency sending rule of another station on a group of continuous sub-carriers (201), the pilot frequency sending rule of the station comprises: the group of continuous sub-carriers are divided into two sub-carrier groups, pilot frequencies sent on sub-carriers in the same sub-carrier group have identical amplitudes and phases, and pilot frequencies sent on sub-carriers in different sub-carrier groups have identical amplitudes but opposite phases, and the pilot frequency sending rule of another station comprises: pilot frequencies sent on various sub-carriers have identical amplitudes and identical phases; and the station sending pilot frequencies according to the pilot frequency sending rule of the station (202). The embodiments of the present invention can reduce the complexity for solving phase deviation.
