The networking mode indication method includes: a base station sends a message to a terminal, wherein the message is used for indicating that the base station applies a segment networking mode.

Therefore, the system capacity is improved.

Description

TECHNICAL FIELD The present invention relates to the field of communications, and in particular to a method for indicating a networking mode, a method for determining a frequency partition, and a system. Background Art In a wireless communication system, a base station is a device that provides a service to a terminal. The base station communicates with the terminal through the uplink and downlink links, the downlink refers to the direction from the base station to the terminal, and the uplink refers to the direction from the terminal to the base station. Multiple terminals can transmit data to the base station through the uplink at the same time, or can receive data from the base station through the downlink at the same time. The main basis for resource mapping of radio resources in a wireless communication system is the frame structure and resource structure of the radio communication system. The frame structure describes the overall control structure of the radio resources in the wireless communication system, and mainly represents the division in the time domain. The resource structure describes the allocation structure of the radio resources in the wireless communication system, and the main performance is the division in the frequency domain. . In future wireless communication systems (for example, wireless based on Orthogonal Frequency Division Multiplexing (OFDM) and Orthogonal Frequency Division Multiple Access (OFDMA) technology) In a communication system, a frame structure generally has the following features: The radio resources are divided into super frames, frames, subframes, and symbols for scheduling. First, the radio resources are divided into time-continuous superframes, each superframe consists of multiple frames, and each frame contains multiple sub-frames, which are composed of the most basic OFDM symbols, super-frame frames, sub-frames, and OFDM symbols. The number is determined by the basic parameters of the OFDM system. In order to improve transmission efficiency, multiple subframes may be cascaded for unified scheduling. For example, in the frame format of the Institute for Electrical and Electronic Engineers (IEEE) 802.16m system shown in Figure 1, the radio resources are divided into superframes in the time domain, and each superframe contains four frames. Frame, each frame contains 8 subframes, and the subframe consists of 6 (or 5 or 7) basic OFDM symbols. The main features of the resource structure of a wireless communication system are: Dividing wireless resources into multiple frequency partitions

(Frequency Partition, FP for short), each user can be independently scheduled in each frequency partition. A specific example in an IEEE802.16m system is shown in Figure 2. The available physical subcarriers of one subframe are divided into four frequency partitions. (FPO, FP1, FP2, FP3), each frequency partition is divided into sets Chinese and distributed resources are used to achieve scheduling flexibility. In a wireless communication system in which a base station implements radio resource scheduling control, many parameter assignments of the system are transmitted by the base station by broadcasting, multicast, or unicast messages (the broadcast message refers to a message sent by the base station to all users, and all accessed users) The multicast message refers to the message sent by the base station to a part of the user, and is only received by the user in the specific group to which the message is associated; the unicast message refers to the message sent by the base station to a specific user, only the designation The user receives) sending parameters to the terminal. For example, in a communication system using the IEEE802.16m protocol, the allocation of common parameters that must be known by the network elements in many systems is transmitted by the base station by sending various types of broadcast messages, for example: - Primary-Super Frame Header I Secondary - Super Frame Header (P-SFH/S-SFH), which passes the corresponding information element (Information Element, in S-SFH). Referred to as IE), the relevant information is sent to each terminal. If the terminal can correctly receive the information in the relevant secondary superframe header, Related parameters can be read and sent to the base station common instructions, and taking corrective action in accordance with Bian appropriate parameters and instructions. And for some specific users, the base station can send various unicast management messages to pass the corresponding parameters to the corresponding terminals. In a wireless communication system based on orthogonal frequency division multiplexing and orthogonal frequency division multiple access (OFDM) technology, the same frequency interference of terminals in other cells received by the base station in the cell, that is, interference between uplink cells; The intra-cells in other cells are interfered by the same frequency, that is, the inter-cell interference. The inter-cell interference and the inter-cell interference are collectively referred to as inter-cell interference. Reducing the impact of inter-cell interference on system performance is an important goal of OFDM system design. If the interference between cells is severe, the system capacity will be reduced, especially the transmission capacity of the cell edge users will be reduced, which will affect the coverage capability of the system. Terminal performance. In order to effectively overcome the inter-cell interference, it is necessary to reasonably plan the uplink frequency resources used by each sector, and try to make the frequency resources used by adjacent sectors orthogonal to each other, and reduce or avoid inter-cell interference. Segment) Mode networking, Segment networking, that is, segmented networking, N base stations can transmit and receive signals on the same frequency resource, but the subcarriers used between each base station are orthogonal to each other, and there is no same frequency. 4 especially. Figure 3 shows a schematic diagram of frequency partitioning in a segment mode network, ^! The available frequency resources are divided into three parts (FP1, FP2, FP3), and three adjacent sectors (sector 1, sector 2, sector 3) use a resource on a frequency partition, so that it can be avoided. Users in three sectors are inter-cells due to the use of the same frequency resources. FIG. 4 is a schematic diagram of frequency partition division of another segment mode networking, dividing available frequency resources into four (FP0, FP1, FP2, and FP3), three sectors (sector 1, sector 2) , sector 3) respectively use a resource on a frequency partition, and share the same frequency resource FP0, This not only avoids inter-cell interference caused by users in three sectors due to the use of the same frequency resources, but also increases the capacity of the system due to the common FP0 resources. In the prior art, the base station uses the segment networking mode to communicate using multiple frequency partitions, which causes the terminal to be unable to determine which frequency partition is available to itself in multiple frequency partitions, which in turn causes communication failure.
