Embodiment Construction

[0029] In the embodiment of the present invention, the signal of the network side equipment in the adjacent cell is measured in each subframe in the subframe set to obtain the measurement result, and the subframe information of the same subframe in the adjacent cell can be obtained according to the measurement result. Since the subframe information of neighboring cells can be obtained when the demand for uplink and downlink service ratios of a cell changes dynamically, the system performance is improved.

[0030] Among them, the embodiments of the present invention can be applied to TDD systems (such as TD-LTE systems), and can also be applied to other systems that need to dynamically adjust subframe uplink and downlink configurations, such as TD-SCDMA systems and their subsequent evolution systems, WiMAX ( Worldwide Interoperability for Microwave Access, Microwave Access Global Interoperability) system and its subsequent evolution system, etc.

Abstract

The embodiment of the present invention relates to the technical field of wireless communication, in particular to a method and an apparatus for determining sub-frame information, which are used for acquiring sub-frame information of a neighbor cell when uplink and downlink service proportion demands in a cell are in the dynamic change. The method provided by the embodiment of the present invention comprises the following steps: measuring a signal of equipment at network side of a neighbor cell in each sub-frame of a sub-frame set, determining a measurement result, wherein the sub-frame of the sub-frame set is determined by the sub-frame type of a sub-frame in a wireless frame configured in the present cell, the sub-frame type of the sub-frame in the wireless frame comprises a variable sub-frame, which is a sub-frame with variable transmission direction; and determining the sub-frame information of the same sub-frame in the neighbor cell according to the measurement result, or reporting the measurement result to an upper layer network node to inform the upper layer network node to determine the sub-frame information of the same sub-frame in the neighbor cell according to the measurement result. By adopting the embodiment of the present invention, when the uplink and the downlink service proportion demands in the cell are in the dynamic change, the sub-frame information of the neighbor cell can be acquired, so that the system performance can be improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and equipment for determining subframe information. Background technique [0002] For the basic duplex mode adopted by the cellular system, the TDD (Time division duplex) mode means that the uplink and downlink use the same working frequency band, and the uplink and downlink signals are transmitted at different time intervals. There is a guard interval (Guard Period, GP) between them; FDD (Frequency division duplex, frequency division duplex) mode means that the uplink and downlink use different working frequency bands, and the uplink and downlink signals can be carried out on different frequency carriers at the same time There is a guard bandwidth (Guard Band, GB) between the uplink and downlink. [0003] The frame structure of the LTE (Long Term Evolution, long-term evolution) TDD system is slightly more complex, such as Figure 1A As shown, a r...
