Embodiment Construction

[0022] In order to illustrate the solution of the present invention more clearly, the configuration of the TDD uplink and downlink subframes is first described below:

[0023] TDD uplink and downlink subframes can be configured in seven ways as shown in Table 1; among them, a wireless frame can contain 10 subframes, and the subframe labels can be marked as: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9; "D" in Table 1 indicates a downlink subframe, "U" indicates an uplink subframe, and "S" indicates a special subframe, in which subframes 3-4, 6-9 are variable , and the subframe 6 includes a special subframe, then without considering the special subframe, it can be considered that the five subframes of subframes 3-4 and 7-9 are variable. That is, subframes with 5-6 bits (bits) in one frame are variable.

Abstract

Provided are a method, an apparatus and a system of operation based on sub-frame group and signaling generation. The base station of the present invention belongs to a TDD system wherein neighbouring cells are able simultaneously to use different uplink and downlink sub-frame allocations; a UE obtains indicating information from two sub-frame groups; said two sub-frame groups are obtained by division of at least one sub-frame among the uplink and downlink sub-frame allocations of the TDD system, the division occurring on the basis of the level of interference of said at least one sub-frame; when an uplink or downlink operation with said base station is performed on said at least one sub-frame, the operation is performed according to the sub-frame group to which said at least one sub-frame respectively belongs. In comparison with the prior art, a UE of the present invention is able to perform corresponding operations on the basis of sub-frame groups which include sub-frames of differing degrees of interference.

Description

technical field [0001] The present invention relates to the field of time division duplex (TDD, Time Division Duplex) communication technology, and in particular to a subframe set-based operation and signaling generation method, device and system. Background technique [0002] Currently, the uplink and downlink subframe configurations of adjacent cells in a TDD system are often the same. However, when the current cell served by the base station has different requirements from its neighboring cells, the current cell needs to change its uplink and downlink subframe configurations, so that the current cell and its neighboring cells adopt different uplink and downlink subframe configurations. Therefore, on some subframes, there will be relatively large inter-cell interference, and on some subframes, the inter-cell interference will be small or even negligible. [0003] Corresponding standards have not been formulated in the prior art so that the TDD system can better adapt to t...
