Embodiment 1

[0057] In this preferred embodiment, the adjacent base stations of BS1 are BS2 and BS3, and the available downlink resources of BS1 are 50 RBs (RB1, RB2, ..., RB50). The serving base station of MS1 is BS1 and the strong interference source is BS3, the serving base station of MS2 is BS2 and has no strong interference source, and the serving base station of MS3 is BS3 and the strong interference source is BS1.

[0058] BS1 completes the allocation of user resources in the cell, and allocates the resources of RB1 to MS1. Among them, MS1 is a cell edge user, and BS1 needs to use a high-power carrier to send data to it;

[0059] BS1 sends RNTP signaling to BS2 and BS3 to indicate the level of carrier transmit power on each RB. Wherein, "0" indicates that the transmission power of the RB is low, and "1" indicates that the transmission power of the RB is high. In this preferred implementation, assuming that only RB1 uses high-power transmission, the format of the RNTP signaling is ...

Embodiment 2

[0065] In this preferred embodiment, the adjacent base stations of BS1 are BS2 and BS3, and the available downlink resources of BS1 are 50 RBs (RB1, RB2, ..., RB50). The serving base station of MS1 is BS1 and the strong interference source is BS3, the serving base station of MS2 is BS2 and has no strong interference source, and the serving base station of MS3 is BS3 and the strong interference source is BS1.

[0066] BS1 completes the allocation of user resources in the cell, and allocates the resources of RB1 to MS1. Among them, MS1 is a cell edge user, and BS1 needs to use a high-power carrier to send data to it;

[0067] BS1, BS2 and BS3 pre-define an RNTP sending rule and receiving method;

[0068] BS1 sends RNTP signaling twice consecutively to BS2 and BS3; wherein, the first RNTP signaling is used to indicate the level of carrier transmit power on each RB of the base station. Wherein, "0" indicates that the transmission power of the RB is low, and "1" indicates that th...

Abstract

The invention discloses a scheduling method and device. The method is applied to a base station and the base station executes the following steps: receiving the information of the transmitting power information of a neighbor base station on a scheduling unit and downlink interference strength information which are transmitted from the neighbor base station, wherein the downlink interference strength information is used for indicating the neighbor base station of whether users scheduled in the scheduling unit are subjected to the interference of the base station; according to the received information of the transmitting power of the neighbor base station and the downlink interference strength information, adjusting the scheduling unit used by the base station and/or the transmitting power used in the scheduling unit. According to the invention, interference among cells can be avoided and resources can be saved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a scheduling method and device. Background technique [0002] In the wireless communication system, the base station communicates with the terminal through the uplink and downlink, the downlink (forward) refers to the direction from the base station to the terminal, and the uplink (reverse) 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] In the Orthogonal Frequency Division Multiplexing (OFDM) system, when the base station and the terminal in the same cell perform downlink data transmission, the downlinks of these terminals are orthogonal to each other, so the interference in the cell can be avoided . However, the downlinks of terminals in different cells may not be orthogonal, so...
