Abstract

The embodiment of the invention provides a transmission method and device. The method comprises the following steps: configuring protection gaps (GPs) of a first resource and a second resource by a base station, wherein subcarrier gaps of data channels mapped in the first resource and the second resource are the same, and the GPs of the first resource and the second resource are different; and performing transmission through the first resource and the second resource. Thus, the base station performs flexible resource configuration based on UE (User Equipment).

Description

technical field [0001] The present invention relates to the communication field, in particular to a transmission method and device. Background technique [0002] In a Time Division Duplexing (TDD) system, in order to reduce the interference between uplink and downlink transmissions of different users, a guard period (Guard Period, GP) is configured between downlink transmission and uplink transmission. [0003] In the prior art, such as figure 1 As shown, D (Downlink) in the figure represents resources for downlink transmission, U (Uplink) represents resources for uplink transmission, figure 1 The subcarrier spacing in the resources shown is the same, and for resources with the same subcarrier spacing, the GP length configurations are the same, for example, the lengths of GP1, GP2, and GP3 are the same. Therefore, for resources with the same subcarrier, the GP configuration is the same, that is, cell-level configuration, resulting in low resource configuration flexibility....
