Problems solved by technology

[0008] In addition, the old version of LTE terminal does not support the dynamic change of subframe type (uplink or downlink). At the same time, conversion and guard time are required between uplink and downlink subframes. Any change of subframe type will require a lot of guard time overhead, reducing resource efficiency

Embodiment 1

[0084] The base station sends the uplink and downlink configurations with configuration index 0 in Table 1 to the user terminal through a broadcast signaling or terminal-specific signaling, and the user terminal determines the fixed downlink subframes and special subframes in the radio frame according to the uplink and downlink configurations. Subframes; specifically, the subframes in the wireless frame that have the same subframe numbers as the downlink subframes and special subframes in the uplink and downlink configurations whose configuration index is 0 are determined as fixed downlink subframes and special subframes, then the In the wireless frame, subframes with subframe numbers 0 and 5 are fixed downlink subframes, and subframes with subframe numbers 1 and 6 are special subframes;

Abstract

Provided are a method and device for monitoring a subframe of a communication system. The method includes: a base station sending information for indicating subframe configuration to a user terminal; the user terminal determining the type of the subframe in a wireless frame according to the information for indicating subframe configuration; and further configuring the dynamic subframe determined as having been obtained according to preset conditions. Also provided is a device for monitoring a subframe of a communication system, wherein subframes of the type such as fixed uplink subframe, fixed downlink subframe and special subframe and so on are determined as having been obtained according to the information for indicating subframe configuration, which achieves good compatibility with the old version LTE terminals, reducing the protection time overhead required for changing the subframe type. Moreover, the dynamic change demand of the up / downlink traffic is better met by increasing the number of types of dynamic subframe, improving the utilization efficiency of the resources, and at the same time, it is easy to be implemented, reducing the costs of re-development.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and device for monitoring subframes of a communication system. Background technique [0002] The frame structure of the Long Term Evolution (LTE) system and the Time Division Duplex (Time Division Duplex, TDD) mode of the LTE-Advanced system (also known as the second type of frame structure, namely frame structuretype 2) is as follows figure 1 As shown, in this frame structure, a radio frame of 10ms (307200Ts, 1ms=30720Ts) is divided into two half-frames, and each half-frame is 5ms long (153600Ts). Each half frame contains 5 subframes with a length of 1ms. The uplink and downlink configuration of the wireless frame is shown in Table 1: [0003] [0004] Table 1 [0005] Among them, D represents a downlink subframe used to transmit downlink signals; U represents an uplink subframe used to transmit uplink signals; S represents a special subframe, including three sp...
