Problems solved by technology

Each base station does not take into account the cell where the carrier of the adjacent base station is turned off when performing carrier cut-off. It is possible that the same carrier is reserved, and the two base stations transmit services on this carrier, resulting in interference interference

Embodiment 1

[0047] An embodiment of the present invention provides a carrier cut-off method, such as figure 1 As shown, the method includes the following steps:

[0048] 101. The adjacent base station sends carrier off state information to the base station.

[0049] Wherein, the carrier cut-off state information indicates the carrier that the adjacent base station turns off. In addition, the carrier-off state information may be a new signaling different from the existing interactive signaling between base stations, or it may be a field added to the existing eNB configuration update (evolved base station configuration update) signaling to indicate that neighboring base stations off the carrier. Exemplarily, the added fields may be as shown in Table 1.

Abstract

The invention provides a carrier cutting method and a base station, and relates to the technical field of communication. The method is used for avoiding the interference from an adjacent cell during the cutting of carriers. The method comprises the steps that the base station receives the carrier cutting state information transmitted by an adjacent base station, wherein the carrier cutting state information indicates the carrier cut by the adjacent station; the base station determines the carrier cut by the adjacent base station according to the carrier cutting state information; the base station determines a business carrier set of the adjacent base station according to the carrier cut by the adjacent base station, wherein the business carrier set comprises all carriers, except the carrier cut by the adjacent base station, in a preset carrier set of the adjacent station; the base station determines a cut carrier set, wherein the cut carrier set is the intersection of the preset carrier set of the base station with the business carrier set of the adjacent base station; the base station cuts each carrier in the cut carrier set.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a method for turning off a carrier and a base station. Background technique [0002] In order to make full use of existing frequency resources in the LTE system, a dual-carrier co-coverage scheme is proposed, which can improve system throughput and user perception. Specifically, when the coverage of two frequency points in each sector is exactly the same, one carrier is used as a coverage cell, and the other is used as a capacity absorption cell. Users can perform uplink and downlink services through the coverage cell and the capacity absorption cell. [0003] At the same time, for the networking scenario of dual-carrier co-coverage, the carrier-off technology is proposed, so that when the network is relatively idle and the traffic volume of the cell is low, the green energy-saving mode can be activated through the carrier-off technology. For example, the PRB o...
