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;

[0085] Similarly, the base station sends the uplink and downlink configurations with configuration index 2 in Table 1 to the user terminal through a broadcast signaling or terminal-specific s...

Abstract

The invention provides a method and an apparatus for monitoring subframes in a communication system. The method comprises: sending a message used for indicating configuration of the subframes to a user terminal by a base station; according to the message used for indicating the configuration of the subframes, determining types of the subframes in a radio frame by the user terminal; further configuring determined dynamic subframes. In the method for monitoring subframes in the communication system, the types of the subframes such as a fixed upstream subframe, a fixed downstream subframe, special subframe, etc. are determined and obtained according to the message used for indicating the configuration of the subframes. The method realizes good compatibility with an LTE terminal of an older version and reduces guard time required for changes of the subframe types. In addition, through adding the dynamic subframe type, dynamic change needs of an upstream business volume and a downstream business volume are preferably satisfied, use efficiency of resources is improved. Meanwhile, the method is easy to realize, and cost of redevelopment is reduced.

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, that is, frame structure type 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...
