Embodiment 1

[0072] This embodiment provides a method for allocating communication resources, such as figure 1 As shown, the method includes:

[0073] 101. The first base station sends configuration information to a user equipment UE, so that the UE uses uplink resources to send data or information to the first base station according to the configuration information.

[0074] Wherein, the configuration information is used to indicate that specific uplink resources are reserved among the uplink resources, and the reserved specific uplink resources may be used to transmit communication information between the first base station and the second base station. Generally, the communication between the first base station and the second base station may use part or all of the reserved specific uplink resources, or may not use the reserved specific uplink resources in a certain subframe. It should be noted that although the reserved specific resource can be used to transmit the communication betwee...

Embodiment 2

[0084] This embodiment provides a method for allocating communication resources, such as figure 2 As shown, the method includes:

[0085] 201. A user equipment UE receives configuration information sent by a first base station.

[0086] Wherein, the configuration information is used to indicate that specific uplink resources are reserved in the uplink resources, and the specific uplink resources are used to transmit communication information between the first base station and the second base station.

[0087] 202. The UE uses uplink resources to send data to the first base station according to the configuration information.

[0088] Specifically, the UE using the uplink resource to send data to the first base station according to the configuration information includes: the UE using the OFDM symbol (or SC-FDMA symbol) where the specific uplink resource is located ) other than uplink resources to send data to the first base station.

[0089] Optionally, before the UE sends d...

Embodiment 3

[0094] This embodiment provides a method for allocating communication resources, in which part or all of the SRS resources are reserved in the uplink resources as a coordination channel, and the coordination channel is used to transmit communication information between the sending base station and the receiving base station, The part or all may be a part or all of a certain subframe. In this embodiment, the communication system includes a transmitting base station, a receiving base station, and a user equipment UE, and the UE is controlled by the transmitting base station, such as image 3 As shown, the method includes:

[0095] 301. The transmitting base station determines to reserve part or all of the SRS resources as a coordination channel.

[0096] For example, the sending base station determines the size of the reserved SRS resource according to the amount of data interaction with the UE or the receiving base station. When it is less, it is necessary to reserve less SRS ...

Abstract

The embodiment of the present invention discloses a method for allocating communication resources, a base station, and user equipment, and relates to the field of communication technology. The method includes: the first base station sends configuration information to the user equipment UE, so that the UE according to the configuration information Using uplink resources to send data to the first base station, the configuration information is used to indicate that specific uplink resources are reserved in the uplink resources; the first base station sends communication information to the second base station on the specific uplink resources . The invention is applicable to the transmission of communication information among multiple base stations.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method for allocating communication resources, a base station and user equipment. Background technique [0002] In the cellular mobile communication scenario, we call the communication link between multiple eNBs (evolution Node B, base station) Backhaul (backhaul line), and the communication information is transmitted between the multiple base stations through the Backhaul. The network quality of Backhaul directly affects the quality of network services provided by operators to users. With the gradual increase of operating cost pressure and bandwidth pressure brought by the development of data services, the optimization of Backhaul transmission has become a hot issue that operators are most concerned about. [0003] The existing backhaul links are divided into two types: wired links and wireless links. Wired links are used to set up lines between multiple ...
