Description

Signaling control method in the wireless communication system and device
Technical field
This method relates to wireless communication technology field, signaling control method and device in particularly a kind of wireless communication system.
Background technology
In the wireless communication system, the base station is the equipment that service is provided to terminal.The base station communicates by uplink and downlink link and terminal, and the direction of terminal is arrived in the descending base station that is meant, the up direction that is meant terminal to base station.A plurality of terminals can send data by up link to the base station simultaneously, also can receive data simultaneously from the base station by down link.
The main foundation of the resource of Radio Resource mapping is the frame structure and the resource structures of this wireless communication system in the wireless communication system.Wherein, frame structure has been described the whole control structure of Radio Resource in the wireless communication system, mainly shows the division on the time domain, and resource structures has been described wireless resource allocation structure in the wireless communication system, mainly shows the division on the frequency domain.
In the wireless communication system in future (for example, in the wireless communication system based on orthogonal frequency division multiplex OFDM and OFDM OFDMA technology), frame structure generally has following feature: Radio Resource is divided into superframe, frame, subframe and symbol dispatches.At first Radio Resource is divided into continuous superframe of time, each superframe comprises a plurality of frames, each frame comprises a plurality of subframes again, and subframe is made up of the most basic OFDM symbol, and the number of frame, subframe and OFDM symbol is by the basic parameter decision of ofdm system in the superframe.In order to improve efficiency of transmission, a plurality of subframes can be carried out cascade and unify scheduling.A kind of frame format of IEEE 802.16m system for example shown in Figure 1, Radio Resource is divided into superframe on time domain, and each superframe comprises 4 frames, and each frame comprises 8 subframes, and subframe is made up of 6 basic OFDM symbols.
The principal character of the resource structures of wireless communication system is: Radio Resource is divided into a plurality of frequency partition (Frequency Partition, FP), can independently dispatch each user in each frequency partition, concrete example in IEEE802.16m system as shown in Figure 2, the available physical subcarrier of a subframe is divided into 4 frequency partition (FP 0, FP 1, FP 2, FP 3), each frequency partition is divided into centralized resources and distributed resource and is used to realize the flexibility of dispatching.
In the wireless communication system that adopts the control of base station realization wireless resource scheduling, (broadcast is meant that the base station sends to all users' message, and the user of all accesses can both receive by sending broadcasting, multicast or unicast messages by the base station in many parameters distribution of system; Multicast message is meant that the base station sends to a part of user's message, and only the user in the associated particular group of this message just receives; Unicast messages is meant that the base station sends to certain specific user's message, only this designated user receives) parameter is sent to terminal, such as, in the communication system of using the IEEE802.16m agreement, the distribution of the common parameter that many intrasystem network elements all must be known passes through to send polytype broadcast by the base station, wherein have such as P-SFH/S-SFH (Primary-Super Frame Header/Secondary-SuperFrame Header or Chinese are called master-superframe head/secondary-superframe head), (information element or Chinese are called information element by corresponding IE in S-SFH, information word) relevant information is sent to each terminal, receive after the information in the relevant secondary superframe head if terminal can be correct, just can read the common instruction that send relevant parameter and base station, and take correct action according to relevant parameters and instruction.And some is to specific user, and the base station can send various unicast management message relevant parameters is passed to relevant terminal.
With Long Term Evolution (Long Term Evolution, be called for short LTE, a kind of 4G communication standard), Ultra-Mobile Broadband (Ultra Mobile Broadband, be called for short UMB, a kind of communication standard) and IEEE 802.16m be that the future broadband wireless communication systems of representative is owing to adopted orthogonal frequency division multiplex OFDM (Orthogonal Frequency Division Multiplexing) and OFDM OFDMA (Orthogonal Frequency Division MultipleAddress) technology, for providing high-speed data and smooth multimedia service that technical guarantee is provided, but new constraint has been proposed also for system's control and RRM.At first, the increasing system bandwidth that causes future broadband wireless communication systems to take of message volume is increasing, and day by day nervous frequency resource has proposed a difficult problem to this, in order to make full use of frequency resource, future broadband wireless communication systems needs nearly possible simplification signaling control, reduce signaling consumption, break through this bottleneck of signaling as far as possible; In addition, disturb the principal element that has become the restriction development of wireless communication systems, and in order to support such as interference suppression measures such as power controls, the base station need be used to some to disturb the information of inhibition, send to terminal such as uplink power control IoT (interference-to-noise ratio) correction parameter (IoT correction value for UL power control) or other parameters, and these information are normally relevant with frequency partition.Perhaps need disturbing the value that suppresses to proofread and correct to send to terminal for up Sounding channel, here up Sounding channel is that some communication system is (such as IEEE802.16m, LTE etc.) a kind of measured channel of using in is used for wireless channel environment is carried out the measurement of some parameter.
The sending method that has a kind of uplink power control IoT correction parameter at present, for example, the base station has 4 frequency partition at most, if the uplink power control IoT corrected value (IoT Correction value for UL PowerControl) of each frequency partition of terminal need be notified in the base station so, the base station can use some bits (such as the N bit) to represent its occurrence for each uplink power control IoT corrected value, the uplink power control IoT corrected value of these four frequency partition all can be indicated in a signaling, thereby the uplink power control IoT corrected value information that needs to send the 4N bit in signaling, but in fact, not all base station all can be divided into the frequency partition of oneself 4, the frequency partition number that each base station is divided may be different, for the base station of having divided the frequency partition that is less than 4, need to send the uplink power control IoT corrected value information of 4N bit equally, here be a big waste, though realized relevant signaling function, but cause signaling consumption too fat to move, waste system resource, reduced spectrum efficiency.
