Description

TECHNICAL FIELD The present invention relates to the field of communications, and in particular to a resource scheduling method and a base station. BACKGROUND OF THE INVENTION In a data transmission system in which a base station performs scheduling control, scheduling allocation of all resources of a system is usually performed by a base station, for example, a resource allocation situation when a base station performs downlink transmission, and a resource situation that can be used when the terminal performs uplink transmission. These are all scheduled and allocated by the base station. In the Orthogonal Frequency Division Multiplexing (OFDM) system, when the base station and the different terminals perform downlink data transmission in the same sector, since the downlinks are orthogonal to each other, the fan can be avoided. Thousands of 4 in the district. However, the downlink between different sectors may not be orthogonal, so each terminal may be subject to downlink interference from base stations of other neighboring sectors, i.e., inter-sector interference. If the interference between the sectors is severe, the system capacity will be reduced, especially the transmission capacity of the sector edge users, which will affect the coverage capability of the system and the performance of the terminal. In order to overcome inter-sector interference and ensure a certain bandwidth utilization, the interference coordination technique in the time-frequency domain can be used to allocate different sub-band resources to the edge terminals to reduce the inter-sector strength between the sectors. The time-frequency domain is coordinated by the inter-sector coordination, and the time-frequency domain channel resources of the uplink and downlink transmission channels of each sector are limited. For example, between adjacent sectors, a portion of the inter-sector (may be all) shared time-frequency resources are divided into multiple sub-sets, each sector occupies one or more sub-set time-frequency resources for data of sector edge users. And signaling transmission. The subset of time-frequency resources occupied by adjacent sectors at the edge of the sector does not coincide. The method for dividing the fixed time-frequency resource set has the advantages of simple configuration and less interaction information between the base stations. The disadvantage is that when the load of the edge users of adjacent sectors is unbalanced, resources are wasted. For the method of dividing the variable time-frequency resource set, the advantage is that the size of the available time-frequency resource set of each sector can be changed in real time according to the load condition of each sector edge user, and the resource can be effectively utilized. The disadvantage is that the interactive information overhead of adjacent sectors is too large and the implementation is complicated. The resource utilization method in the related art has a relatively low resource utilization or a large amount of interactive information, and the implementation is complicated.

Embodiment 1 This embodiment provides a resource scheduling method. This embodiment combines the foregoing embodiments and preferred embodiments thereof. Step 1: First number the sectors, and number the three adjacent sectors under the same base station according to the direction of the main lobe of the antenna, respectively, as 1, 2, 3; the time-frequency resources available for terminal scheduling are determined according to certain The rules are sorted. It is assumed that all time-frequency resources can be divided into N3 according to the minimum schedulable time-frequency resource particles, which are numbered as 1, 2, ... Nl, Nl+1, ... N2, N2+1, respectively. ...N3-1, N3. Then ^¹ The resource is divided into three parts, which are denoted as Fl, F2, and F3, and are respectively assigned to three sectors, as follows: For the sector numbered 1, the time-frequency resource particles 1 , 2...N1 are a set F1 It is regarded as its low-interference area, where the starting position index is 1, the ending position index is N1, and the remaining area is high-interference area; For the sector numbered 2, the set F2 of the time-frequency resource particles Nl+1, N1+2...N2 is regarded as its low-interference area, and the start position index of the area is N1+1, and the end position index is N2, the remaining area is a high-interference area; for a sector numbered 3, the set F3 of time-frequency resource particles N2+1, N2+2...N3 is regarded as its low-interference area, which is The starting position index is N2+1, the ending position index is N3, and the remaining area is the high thousand 4 special area; wherein the Fl, F2, and F3 resource sets are the same size, set to M, and the unit is the minimum time frequency allocated by the scheduling. Resource block. Then M is one third of the total available resource particles, that is, the parameters N1, N2, N3 satisfy: N1=M; N2=2M; N3=3M. That is: the time-frequency resource set F1 is the low-interference area of sector 1, and is the high-interference area of sector 2, 3. The time-frequency resource set F2 is the low-interference area of sector 2, which is the high-interference area of sectors 1 and 3. The time-frequency resource set F3 is the low-interference area of sector 3, which is the high-interference area of sector 1 and 2. Step 2: For the time-frequency set Fl, F2, F3, further divided into two blocks, named fixed area and non-fixed area respectively. Specifically: time-frequency set F1 For sector 1, the fixed area block of F1 is its fixed low-interference area, the non-fixed area block of F1 is its non-fixed low-interference area, and for sector 2 and fan Zone 3, F1's fixed area block is its fixed high-interference area, and F1's non-fixed area block is its non-fixed high-interference area. Based on the same concept: Time-frequency set F2 For sector 2, the fixed area block of F2 is its fixed low-interference area, and the non-fixed area block of F2 is its non-fixed low-four area, and for sectors 1 and sector 3, the fixed area block of F2 is its fixed high-thousand-four area, and the non-fixed area block of F2 is its non-fixed high-interference area. Time-frequency set F3 For sector 3, the fixed area block of F3 is its fixed low-interference area, the non-fixed area block of F3 is its non-fixed low-interference area, and for sector 1 and sector 2, The fixed area block of F3 is its fixed high-interference area, and the non-fixed area block of F3 is its non-fixed high-thousand area. The size of the non-fixed low-interference area is SI_SIZE, which can be specified by the protocol or by the upper network unit, but must satisfy 0<= SI_SIZE <=M. The classified time-frequency resource set is classified as shown in Figure 2. The three-sector high-thousand-four area (including the fixed high-thousand-four area and the non-fixed high-thousand-four area), and the low-interference area (including fixed low) See the schematic diagram for the indication of the interference zone and the non-fixed low-interference zone. It should be noted that when the base station allocates scheduling resources to the user, the scheduling of resource allocation according to the order of the above resource numbers is regarded as positive sequence scheduling (including the sequence after cyclic shift), for example: 1 , 2, ... The order of Nl , Nl+1 , ...N2, N2+1, ...N3-1, N3 is positive order. The sequential scheduling that is exactly opposite to the positive sequence is the reverse order scheduling. Optionally, for the foregoing division of time-frequency resources, all time domain resources may be included by default, and only frequency domain resources are distinguished. For sectors numbered 1, the sector numbered 2 is considered the first adjacent sector, and the sector numbered 3 is considered the second adjacent sector. For a sector numbered 2, a sector numbered 3 is considered the first adjacent sector, and a sector numbered 1 is considered the second adjacent sector. For sectors numbered 3, the sector numbered 1 is considered the first adjacent sector, and the sector numbered 2 is considered the second adjacent sector. Step 3: After the user accesses the base station, the base station determines the user type according to the feedback information of the user: the central user and the edge user, wherein the feedback information may be at least one of the following: Received signal strength indication information (Receedd) Signal Strength Indication (RSSI), Signal to Interference plus Noise Ratio (SINR), Signal to Interference Ratio (SIR) „ When the user needs to schedule When the resource is used, the base station allocates the corresponding time-frequency resource according to the user type, as follows: For the edge user, the base station allocates the time-frequency resource of the low-interference area, and preferentially allocates the time-frequency resource of the fixed low-interference area, and allocates the time-frequency resource. Then allocate the time-frequency resources of the non-fixed low-interference area. If the resources are still insufficient, according to the SI information exchanged between the base stations, the time-frequency resources of the non-fixed high-throw area are preferentially used or competed with the inner ring users. For the central user, the base station allocates time-frequency resources of the high-interference area to The time-frequency resources of the fixed high-thousand-thousand-thousand-thousand-thousand-thousand-thousand-thousand-thousand-seven areas are allocated first, and the time-frequency resources of the non-fixed high-thousand-thousand-thousand-area areas are allocated after the allocation is completed; or, the priority is not imposed on the central user. Method: The base station sends the SI indication information to the adjacent sector according to the resource scheduling situation of the sector non-fixed low-interference area at the current time, and the size of the information is as described above. SI_SIZE, according to the number order of the time-frequency resource particles, respectively indicates that the resource particle is scheduled to be used by the edge user, for example: if the time-frequency resource particle has been scheduled and used by the edge user of the sector, it is identified by 1 if not Used by the edge user of the sector, it is identified by 0. The SI signaling can be sent via a wired interface or a wireless air interface. Preferably, for the transmission timing of SI signaling: periodic transmission may be used, event triggered transmission or by the upper layer network unit. Preferably, after the neighboring base station receives the SI information of the SI_SIZE bit, if the edge user can allocate insufficient resources, the time-frequency resource that is not used by the edge user in the non-fixed low-interference area of the adjacent sector may be used. That is, the corresponding time-frequency resource block in the non-fixed high-interference area of the sector. Specifically, if the base station receives the 0 identifier in the SI information from the first neighboring sector, the sector may use the second neighboring sector to identify all the time-frequency resource particles that are not used, and perform the reverse order according to the number. Scheduling use. If the base station does not include the 0 identifier in the SI information from the first neighboring sector, the sector may use the second neighboring sector to identify the unused time-frequency resource particles, and perform scheduling according to the number reverse order. . Based on the same idea: if the base station receives the 0 identifier in the SI information from the second neighboring sector, the sector may use the first neighboring sector to identify all the time-frequency resource particles that are not used, and according to the number Scheduled for use. If the base station receives the SI information from the second neighboring sector and does not include the 0 identifier, the sector may use the first neighboring sector to identify unused time-frequency resource particles, and perform scheduling according to the number order. . If the base station does not include the 0 flag in the SI information of two adjacent sectors, the non-fixed low-interference resources of other sectors may not be used. Preferably, for the outer ring user, the scheduling resource priority is: fixed low-interference area, non-fixed low-interference area, non-fixed high-interference area (identified by SI;). For inner loop users, the scheduling priority is: fixed high-interference area, non-fixed high-interference area. It should be noted that the upper network unit adjusts the size of the SI_SIZE according to the current network load. If the edge load of the three sectors is seriously unbalanced, the value of SI_SIZE may be increased, otherwise, the value may be decreased. In the limit case, if three sectors are used. For edge load balancing, the SI_SIZE value can be set to 0, that is, there is no need to send SI information; otherwise, the SI_SIZE value can be increased to the maximum, that is, equal to the size of Fl, F2, and F3. Preferably, one or more of the foregoing configuration information and a specific division method of the time-frequency resource block may be configured by default according to the protocol, or may be notified by the upper-layer network element to notify the base station. The upper layer network element here may be a relay device, a base station controller, an access service network, a connection service network, a core network gateway, or the like. It should be noted that the resource allocation method provided in this embodiment is applicable to uplink (the transmitting end is the terminal user, the receiving end is the base station), the communication system, and the downlink (the transmitting end is the base station, and the receiving end is the terminal user). The resource scheduling of the communication system .

The same time-frequency resources, thereby reducing the interference and improving system throughput. Embodiment 2 This embodiment provides a resource scheduling method. This embodiment combines the foregoing embodiments and preferred embodiments thereof. FIG. 5 is a flowchart of resource scheduling according to a preferred embodiment of the present invention, as shown in FIG. The method includes: Step S501: When the wireless communication system is initialized, the system divides the time-frequency resources available for allocation into three parts, namely, Fl, F2, F3, and then according to the configured SI_SIZE parameter, further Fl , F2, F3 is divided into fixed area i or non-fixed area i or. Step S502: The base station determines, according to its own sector number, a non-fixed high-interference area in the sector, a fixed low-interference area, and a non-fixed low-interference area. Step S503: After the terminal user accesses the system, the base station determines its type according to the feedback information: the central user and the edge user, wherein the feedback information may be at least one of the following: Received Signal Strength Indication Information (Received Signal) Strength Indication (referred to as RSSI), Signal to Interference plus Noise Ratio (SINR), Signal to Interference Ratio (SIR), channel quality including channel quality indicator (Channel Quality Information, referred to as CQI) or Channel State Information (CSI). Step S504, determining whether it is an edge user, if the determination result is yes, that is, the edge user, the process proceeds to step S505; if the determination result is negative, that is, the center user, the process proceeds to step S506. In this implementation For example, when the terminal user needs to schedule resources, the base station allocates time-frequency resources according to the user type. For different types of users, the selection of time-frequency resources follows a different rule sequence. Step S505: The base station allocates time-frequency resources of the low-interference area, and preferentially allocates time-frequency resources of the fixed low-interference area, and allocates time-frequency resources of the non-fixed low-interference area after the allocation is completed. Step S506: The base station allocates time-frequency resources of the high-interference area to the time-frequency resources of the high-interference area, and allocates the time-frequency resources of the fixed high-thousand-thousand-thousand-area area after the allocation is completed; The center user does not make the above priority restrictions. Step S507, the base station determines whether there is any time-frequency resource of the remaining low-interference area, if yes, assigns to the inner ring user, and executes step S510. If not, it does not allocate, and step S509 is performed. Optionally, when the resources of the inner loop user are insufficient, and the inner loop user has remaining resources, the inner loop user can also invoke the resources of the low-interference area. For the uplink communication system, the terminal needs to be transmitted. The power is appropriately limited, that is, the transmission power of the outer ring user terminal is reduced. In step S508, it is determined whether there is a video resource allocation in the high-level area. If the determination result is yes, after the allocation is successful, step S510 is performed. If the time-frequency resource of the high-level area is insufficient, the process proceeds to step S511. Step S509: The base station preferentially or competes with the inner ring user for using the time-frequency of the non-fixed high-interference area of the sector that is not scheduled by the edge user, according to the received SI indication information from the adjacent sector. The resource (the time-frequency resource of the non-fixed high-interference area of the sector is the time-frequency resource of the non-fixed low-interference area of the adjacent sector). Specifically, if the base station receives the 0 identifier in the SI information from the first neighboring sector, the sector may use the second neighboring sector to identify all the time-frequency resource particles that are not used, and perform the reverse order according to the number. Scheduling use. If the base station does not include the 0 identifier in the SI information from the first neighboring sector, the sector may use the second neighboring sector to identify the unused time-frequency resource particles, and perform scheduling according to the number reverse order. . Based on the same idea: if the base station receives the 0 identifier in the SI information from the second neighboring sector, the sector may use the first neighboring sector to identify all the time-frequency resource particles that are not used, and according to the number Scheduled for use. If the base station receives the SI information from the second neighboring sector and does not include the 0 identifier, the sector may use the first neighboring sector to identify unused time-frequency resource particles, and perform scheduling according to the number order. . It should be noted that if the base station does not include the 0 identifier in the SHU of two adjacent sectors, the non-fixed high-interference resource of the sector may not be used. Step S510, ending. Step S511, the base station allocates the remaining resources of the area, and if not, does not allocate, and step S510 is performed. In this embodiment, the method for transmitting the SI signaling is as follows: the base station sends the SI indication information to the adjacent sector according to the resource scheduling situation of the sector non-fixed low-interference area at the current time, and the size of the information is the above SI_SIZE, according to The number order of the time-frequency resource particles indicates that the resource particle is scheduled to be used by the edge user, for example: if the time-frequency resource particle has been scheduled and used by the edge user of the sector, it is identified by 1 if not The edge user of the zone is scheduled to use, and is identified by 0. The SI signaling can be sent via a wired interface or a wireless air interface. Preferably, the transmission timing for the SI signaling includes the following three modes: a periodic transmission, an event triggered transmission, or an upper layer network unit may be specified. Embodiment 3 This embodiment provides a resource scheduling method. The embodiment combines the foregoing embodiments and preferred embodiments thereof. The method includes: Step 1: When the wireless communication system is initialized, the system is available for allocation. The frequency resources are divided into three parts, namely Fl, F2, F3. Each size is recorded as M and then Fl, F2, F3 are further divided into fixed area and non-fixed area according to the initial configuration SI_SIZE parameter. Step 2: The base station determines, according to its own sector number, a non-fixed high-interference area in the sector, and fixes a low-interference area, and a non-fixed low-interference area.

The limit is such that its transmit power is lower than that of the edge user. Step 7. The base station preferentially or competes with the inner ring user according to the received SI indication information from the adjacent sector, and uses the time frequency of the non-fixed high-interference region of the sector that is not scheduled by the edge user. The resource (the time-frequency resource of the non-fixed high-interference area of the sector is the time-frequency resource of the non-fixed low-four area of the adjacent sector). Specifically, if the base station receives the 0 identifier in the SI information from the first neighboring sector, the sector may use the second neighboring sector to identify all the time-frequency resource particles that are not used, and perform the reverse order according to the number. If the base station receives the SI information from the first neighboring sector and does not include the 0 identifier, the sector may use the second adjacent sector to identify the unused time-frequency resource particles, and perform the reverse order according to the number. For scheduling use, assuming that the end location number of the non-fixed area is XI, the time-frequency resource particle number used for scheduling shall not be less than Xl-SI_SIZE/2. Similarly, if the base station receives the 0 identifier in the SI information from the second adjacent sector, the sector may use the first adjacent sector to identify all the time-frequency resource particles that are not used, and enter the sequence according to the number. If the base station receives the SI information from the second adjacent sector that does not include the 0 identifier, the sector may use the first adjacent sector to identify the unused time-frequency resource particles, and according to the number The scheduling is used in sequence. If the starting position number of the non-fixed area is X2, the time-frequency resource particle number used for scheduling shall not be greater than X2+SI_SIZE/2. If the base station does not include the 0 identifier in the SI information of two adjacent sectors, the non-fixed high-interference resource of the sector may not be used. Preferably, for the method for transmitting the SI signaling: the base station sends the SI indication information to the adjacent sector according to the resource scheduling situation of the sector non-fixed low-interference region at the current time, the size of the information is the above-mentioned SI_SIZE, according to the time-frequency The numbering sequence of the resource particles indicates that the resource particle is scheduled to be used by the edge user, for example: if the time-frequency resource particle has been scheduled for use by the edge user of the sector, it is identified by 1 if not For edge user scheduling, it is identified by 0. The SI signaling can be sent via a wired interface or a wireless air interface. Preferably, for the transmission timing of the SI signaling: a periodic transmission, an event triggered transmission or an upper network element designation may be employed. Embodiment 6 This embodiment provides a resource scheduling method. This embodiment combines the foregoing embodiment and a preferred implementation manner thereof. In this embodiment, the parameter SI_SIZE, the non-fixed area, and the fixed area time-frequency resource are not configured.

Edge users, enter step 4 to gather 5. Step 4: The base station allocates a time-frequency resource of a high-interference area to the time-frequency resource of the high-interference area, and allocates a time-frequency resource of the non-fixed high-interference area after the allocation is completed; or, for the central user Do not make the above priority restrictions. If the allocation is successful, the process ends. If the time-frequency resource is insufficient in the high-interference area, the process proceeds to step 4. Step 5: The base station allocates time-frequency resources of the low-interference area, and preferentially allocates time-frequency resources of the fixed low-interference area, and allocates time-frequency resources of the non-fixed area.

The resource (the time-frequency resource of the non-fixed high-interference area of the sector is the time-frequency resource of the non-fixed low-four area of the adjacent sector). Specifically, if the base station receives the 0 identifier in the SI information from the first neighboring sector, the sector may use the second neighboring sector to identify all the time-frequency resource particles that are not used, and perform the reverse order according to the number. If the base station receives the SI information from the first neighboring sector and does not include the 0 identifier, the sector may use the second adjacent sector to identify the unused time-frequency resource particles, and perform the reverse order according to the number. For scheduling use, assuming that the starting position number of the non-fixed area is X, the time-frequency resource particle number used for scheduling shall not be less than Χ+Ν/2. Based on the same idea: if the base station receives the 0 identifier in the SI information from the second neighboring sector, the sector may use the first neighboring sector to identify all the time-frequency resource particles that are not used, and according to the number If the base station receives the SI information from the second adjacent sector without including the 0 identifier, the sector may use the first adjacent sector to identify the unused time-frequency resource particles, and according to The numbering sequence is used for scheduling. If the starting position number of the non-fixed area is X, the time-frequency resource particle number used for scheduling shall not be greater than Χ+Ν/2. If the base station does not include the 0 identifier in the SI information of two adjacent sectors, the non-fixed high-interference resource of the sector may not be used. Preferably, for the method for transmitting the SI signaling: the base station sends the SI indication information to the adjacent sector according to the resource scheduling situation of the sector non-fixed low-interference region at the current time, the size of the information is the foregoing Ν, according to the time-frequency The number order of the resource particles, indicating that the resource particles are scheduled to be used by the edge user. For example, if the time-frequency resource particle has been scheduled for use by the edge user of the sector, it is identified by 1 and is not identified by the edge user of the sector. The SI signaling can be sent through a wired interface or a wireless air interface.
