Embodiment Construction

[0127] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. 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.

[0128] In a traditional communication system, in order to make the coverage of the entire cell larger, both uplink and downlink use low-frequency carriers for communication. For example, in the long-term evolution LTE (Long Term Evolution) system of the prior art, its macro cell uses a low-frequency carrier for communication, so that the air interface access in the downlink direction adopts the OFDMA multiple access method, and the air interface access in the u...

Abstract

The embodiment of the invention discloses a data communication method, a terminal and a base station so that channel resources of a PDCCH are saved and the resource utilization rate of the PDCCH is improved. The method includes the following steps: the terminal receives first scheduling information issued by the base station, wherein the first scheduling information includes shared scheduling information of a first transmission direction and a second transmission direction; using the first scheduling information to carry out data communication with the base station in the first transmission direction; and using at least part of scheduling information in the first scheduling information to carry out data communication with the base station in the second transmission direction. The data communication method, the terminal and the base station are applicable to the field of communication.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data communication method, terminal and base station. Background technique [0002] In order to increase the transmission rate of wireless networks and enhance user experience, a heterogeneous network architecture is proposed. In a heterogeneous network, multiple small base stations are distributed under the macro base station. Generally, the coverage area of ​​this type of small base station is called a small cell. [0003] In a small cell network, due to the small coverage of the small cell, the quality of the uplink and downlink channels is basically the same. Therefore, in the small cell network, both the uplink channel and the downlink channel can use Orthogonal Frequency Division Multiple Access (OFDMA). Division Multiple Access). [0004] When the uplink channel and downlink channel of the small cell both adopt the OFDMA method, the small base station sends the alloc...
