Embodiment 1

[0153] Embodiment 1 (corresponding to the above scheme one)

[0154] The base station BS1 and the terminal MS1 exist in a wireless system at the same time, and BS1 is the serving base station of MS1, and the working carrier frequency is C1, and the carrier frequency resource C1 is used for communication between BS1 and MS1. In addition, the carrier that can be used by this wireless system There are also C2, C3 and C4 as frequency resources. The carrier frequency information measurement process of this embodiment includes the following steps:

[0155] Step 101, BS1 sends a silent period indicator (SilenceIndicator) on the downlink channel through the broadcast channel, which is used to instruct BS1 and the terminal that selects BS1 as the serving base station not to perform any information transmission operation, but to perform carrier frequency information measurement operation.

[0156] Among them, at least the information included in the Silence Indicator signaling is:

[...

Embodiment 2

[0174] Embodiment 2 (corresponding to the implementation of the above scheme 2 without adding a response process)

Abstract

The invention discloses three schemes for a method for measuring carrier frequency information in a wireless communication system. One of the three schemes includes that a base station sends out a quiet period indication signaling at a downlink channel, and a terminal which successfully receives the quiet period indication signaling sent out by the base station measures the carrier frequency information at a first time-frequency resource and feeds back a measurement result of the carrier frequency information to the base station at a second time-frequency resource. The invention also discloses three schemes for a system for measuring the carrier frequency information in the wireless communication system. One of the three schemes includes that a carrier frequency information measurement and feedback unit is used on the condition that the base station sends out the quiet period indication signaling at the downlink channel, the terminal which successfully receives the quiet period indication signaling sent out by the base station measures the carrier frequency information at the first time-frequency resource and feeds back the measurement result of the carrier frequency information to the base station at the second time-frequency resource. By the aid of the method and the system, the base station can know channel quality situations of all terminals on the current carrier frequency.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and system for measuring carrier frequency information in a wireless communication system. Background technique [0002] In a wireless communication system, a base station refers to a device that provides services for a terminal. The base station communicates with the terminal through an up / down link. The downlink refers to the direction from the base station to the terminal, and the uplink refers to the direction from the terminal to the base station. Multiple terminals can simultaneously send data to the base station through the uplink, and can also receive data from the base station through the downlink at the same time. [0003] A wireless communication system usually uses a specific carrier frequency for sending and receiving information between a base station and a terminal, and the selected carrier frequency may be determined by the type of the wireless communication sys...
