Problems solved by technology

[0005] However, when the Pico eNB and the Macro eNB exchange information through the Backhaul link, the Pico eNB adopts the same timing as the Macro UE, which is different from the timing of the communication between the Pico eNB and the micro base station user (Pico UE) in the prior art, resulting in a significant drop in network capacity

Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0029] In a Long Term Evolution (Long Term Evolution, LTE) / Long Term Evolution Advanced (Long Term Evolution Advanced, LTE-A) communication system, network capacity may be improved by adopting a heterogeneous networking manner. Such as figure 1 As shown, the coverage areas of the macro cell and the micro cell are spatially separated, so the two can use the same time-frequency resource for access link (Access Link) transmission. Considerin...

Abstract

The present invention provides a communication method and communication equipment. The method includes: a first base station determines a first time adjustment parameter, the first time adjustment parameter is determined based on the timing of a first subframe, and the first subframe is the A transmission subframe between the first base station and the second base station; the first base station sends the first time adjustment parameter to the terminal, and the first time adjustment parameter is used for the terminal to time the second subframe, The second subframe is a transmission subframe between the terminal and the first base station. In the present invention, the micro base station sends the time adjustment parameter to the terminal, and the terminal timings the subframe of the Pico Access link according to the time adjustment parameter, so as to realize the space division multiplexing of the Backhaul link and the Pico Access link.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a communication method and communication equipment. Background technique [0002] In the existing communication system, the uplink and downlink transmission is performed between the base station and the user equipment (UE), and at the same time, there is a communication link between the base station and the base station, and the subframes transmitted on the communication link occupy the base station and the user equipment (UE). The transmission resources between UEs lead to a decrease in network capacity. [0003] Taking the network system composed of macro base stations and micro base stations as an example, figure 1 It is a heterogeneous scene diagram of a macro base station and a micro base station in the prior art, where the coverage of the pico base station (Pico eNB) is included in the coverage of the macro base station (Marco eNB), when the user equipment (U...
