Abstract

The invention provides a method and a device for processing uplink and downlink resource configuration information. The method comprises a step of transmitting uplink and downlink resource configuration information on a downlink control signaling of a flexible subframe. The invention solves the problems that in a condition that the uplink and downlink configuration is dynamically adjusted in the related technology, when the high level signal realization is adopted, the cycle and the delay are long , and the execution for the signaling between the terminal and the base station is not constant, and that when the physic layer signaling realization is adopted, the cost for the physic layer control signaling is big and the complexity for the device realization is high. The invention can effectively avoid the problems that the high level signaling delay is long and that the understanding for the execution timing of the terminal and the base station inconsistent on the premises that the extra physic layer resources are not occupied, the extra cost for the control signaling is not added and the complexity of the device is not increased, and can realize the highly efficient and precise transmission of the uplink and downlink resource configuration information.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for processing uplink and downlink resource configuration information. Background technique [0002] The Time Division Duplex (TDD for short) system divides uplink (sent by the terminal to the base station) and downlink (sent by the base station to the terminal) resources in the time domain, and usually performs uplink and downlink in units of time slots or subframes. Allocation of resources. Generally, the base station notifies all terminals in the cell of the allocation of uplink and downlink resources by broadcast signaling in a semi-static manner. [0003] figure 1 It is a schematic diagram of the frame structure of the TDD mode of the Long Term Evolution (LTE) system in related technologies, as shown in figure 1 As shown, the frame structure is also called the second type of frame structure (ie, frame structure type2). In this frame structure, a wir...
