Problems solved by technology

[0009] 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...

Embodiment 2

[0089] The base station sends the uplink and downlink configurations with the configuration index of 3 in Table 1 to the user terminal through a broadcast signaling or terminal-specific signaling, and the user terminal determines the fixed downlink subframe in the wireless frame according to the uplink and downlink configuration; specifically Specifically, the subframes in the radio frame with the same subframe numbers as the downlink subframes in the uplink and downlink configurations with configuration index 3 are determined as fixed downlink subframes, then in the radio frame, the subframe numbers are 0, 5, and 6 , 7, 8, and 9 are fixed downlink subframes;

[0090] Similarly, the base station sends the uplink and downlink configurations with configuration index 5 in Table 1 to the user terminal through a broadcast signaling or terminal-specific signaling, and the user terminal determines the fixed uplink sub-configuration in the wireless frame according to the uplink and dow...

Abstract

The invention provides a method and device for monitoring a communication system subframe. The method includes that a user terminal receives information for indicating the subframe configuration from a base station; the user terminal determines the type of the subframe in the radio frame according to the information for indicating the subframe configuration; when the information for indicating the subframe configuration received by the user terminal is the uplink and downlink configuration and the control signaling for indicating the dynamic subframe, the determined type of the subframe in the radio frame is that the user terminal determines the dynamic subframe in the radio frame according to the control signaling for indicating the dynamic subframe; and according to the uplink and downlink configuration, the remaining subframes in the radio frame are determined as one or more of a fixed uplink subframe, a fixed downlink subframe, or a special subframe. The invention further provides a device for monitoring the communication system subframe.

Description

[0001] This application is a divisional application, the application number of the original application is 201110095511.2, the application date is April 15, 2011, and the title of the invention is "Method and device for monitoring communication system subframes" technical field [0002] 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 [0003] 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 wireles...
