 The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for notifying and receiving time slot allocation information. Background technique

As one of the two basic duplex systems, the Time Division Duplex (TDD) mode has received more and more attention in the context of the increasing bandwidth demand for broadband mobile communications. In the TDD system, the uplink and downlink transmissions use the same frequency resource, and the uplink/downlink signals are transmitted on different time slots. In common TDD systems, including 3G Time Division Synchronous CDMA (TD-SCDMA) systems and 4G TD-SCDMA Long Term Evolution (LTE-LTE) systems, uplink and downlink time slots The division is static or semi-static. The usual practice is to determine the proportion of uplink and downlink time slots according to the type of cell and the approximate proportion of services in the network planning process and keep unchanged. This is a relatively simple approach in the context of large coverage of macro cells, and is also more effective. Third Generation Partnership Project ^{(The 3 rd Generation Partnership, 3} GPP) TDD mode of LTE Rel-8/9/10 ( version 8/9/10) preclude the frame structure shown in FIG. 1 with. The uplink and downlink subframe allocation modes support the seven modes shown in Table 1.

 Table 1: Uplink-downlink configurations

随着技术发展， 越来越多的微小区 （Pico cell ), 家庭基站（Home NodeB )等低功率 基站被部署用于提供局部的小覆盖， 在这类小小区 （small cell ) 中， 用户数量较少， 且用 户业务需求变化较大， 因此小区的上下行业务比例需求存在动态改变的情况。 虽然在 TD-LTE标准中也支持在线改变小区的上下行时隙比例， 但需要较为复杂的信令流程和配 置时间， 造成系统性能下降， 也不能跟踪实时的业务变化情况。

With the development of technology, more and more low-power base stations such as Pico cell and Home NodeB are deployed to provide local small coverage. In such small cells, the number of users There are fewer, and the user service needs change greatly. Therefore, there is a dynamic change in the proportion of the uplink and downlink services of the cell. Although the TD-LTE standard also supports online change of the uplink and downlink time slot ratio of the cell, a relatively complicated signaling process and configuration time are required, which causes system performance degradation and cannot track real-time service changes.

Some signaling design schemes are disclosed in the research report 3GPP TR36.828 to support flexible aspects in TDD cells. One-way link-downlink (UL-DL) subframe allocation, in which one way the base station uses the channel or signal of the physical layer to send information indicating the configuration of the TDD uplink and downlink subframes to the terminal, which can support the fastest 10ms changes the uplink and downlink allocation in a radio frame. For example, as shown in FIG. 2, the base station sends the uplink and downlink subframe allocation information in the current or next radio frame to the terminal on a specific physical channel in the subframe 0 in each radio frame.

 According to the current research, the types of small cells are mainly divided into two types: small cells that can work independently and small cells that cannot work independently. The small cell that works independently has the complete function of a cell in the existing system, and supports the terminal in the small. The cell accesses and camps, and the terminal needs to go through the handover process when moving from the Macro base station to the small cell coverage. The non-independent small cell does not have the complete cell function in the existing system and does not support the access and residency of the terminal. For example, a terminal that moves to a coverage of a non-independent small cell does not go through the existing handover process, but maintains its control plane connection (system broadcast, Radio Resource Control (RRC) signaling, etc.). At the Macro base station, only the data plane connection (uplink and downlink service data, scheduling signaling, etc.) is switched to the small cell. Since the terminal does not need to be provided, the non-independent small cell does not need to send system information, etc., so that when there is no service demand, the signal transmission can be reduced or stopped, and the energy saving effect can be realized. The non-independent small cell on/off and other operating states/parameters can be configured by the Macro Base Station. In a TDD system, flexible UL-DL subframe allocation should be supported in independent or non-independent small cells to adapt to service changes and improve system efficiency. However, the prior art has not proposed a unified solution. Summary of the invention
