Description

Resource allocation method

TECHNICAL FIELD The present invention relates to the field of communications, and in particular, to a resource allocation method. BACKGROUND OF THE INVENTION Currently, with the long-term evolution of evolution (Long-Term Evolution Advanced, referred to as

LTE-A) The demand for the cell, the average frequency efficiency of the cell and the efficiency of the cell edge frequency are gradually taken seriously. The uplink and downlink of the LTE-A system are all frequency division systems based on Orthogonal Frequency Division Multiplexing (OFDM) (or some variant of OFDM). Different from the traditional CDMA-based multiple access multiplexing wireless communication system, the LTE-A system has no processing gain. Since the frequency division orthogonal technology is completely adopted in the cell, there is no cell in the LTE-A system. Interference, however, it is relatively difficult to handle the dry 4 at the edge of the cell. Currently, there are three main methods for handling interference at the edge of a cell in the Long-Term Evolution (LTE) system, including: interference randomization, interference cancellation, and interference coordination (avoidance). Among them, interference randomization generally uses frequency hopping, hopping, direct spreading or hopping to mitigate the interference between cells. It does not require network planning and does not require signaling support, but does not fundamentally eliminate interference. Interference cancellation can use some algorithms to eliminate interference. However, additional physical entities are required to eliminate interference. For example, multi-antenna technology is used for interference removal. However, in some cases, interference cancellation cannot be satisfied. The conditions required. Interference coordination (avoidance) is to exchange some information between cells, and use some algorithms to enable each cell to automatically select appropriate resources for transmission according to the feedback information of other cells and its own situation, thereby realizing efficient use of resources between cells. The opportunity of resource collision between cells is alleviated, and finally the performance of the cell edge is improved. The method emphasizes that interference caused by the same time-frequency resources between cells is avoided as much as possible. Since the cell edge users have a small difference in antenna distance from multiple neighboring cells, the use of the transmit antennas of multiple cells to achieve higher capacity and reliable transmission of the wireless link at the cell edge has become the focus of research. In multi-point coordinated transmission, there are also problems of area edge interference, and there is also a problem that multi-point cooperative users are compatible with ordinary users in the node, that is, within the same node, when there is multi-node cooperative service For users, there are differences between the two types of users, from the control information design aspect, the data transmission method, the channel status information, and the quality information. In this way, the target users of the collaborative service and the non-cooperative service target will appear. The problem of how the resources occupied by the user are distributed. However, there has not been proposed a technical solution capable of solving the compatibility problem between the multi-point cooperative user and the non-multipoint coordinated user within the node. SUMMARY OF THE INVENTION The present invention has been made in view of the inability to solve the problem of multi-tenput users and non-multi-site ten users, and the LTE and LTE-A users are compatible within the nodes. Therefore, the main object of the present invention is to provide a An improved resource allocation scheme to solve the above problems.

Specifically, the predetermined mode is one of the following: a time division mode, a frequency division mode, where the time division mode refers to that the resources allocated to the first type of user equipment and the resources allocated to the second type of user equipment are located in different time slots, and the frequency division is performed. The mode refers to that the resources allocated to the first type of user equipment and the resources allocated to the second type of user equipment are located at different frequencies of the same time slot. In addition, in a case where the predetermined mode is the time division mode, the node allocates a blank subframe for the first type of user equipment to perform resource calling, where the number of blank subframes is based on the first type of user equipment.

Moreover, in a case where the node allocates the cooperative resource zone in a semi-static or dynamic manner, the priority of the node assigning the resource zone to the first type of user equipment is higher than the priority of the node assigning the resource zone to the second type of user equipment. In addition, in a case where the node allocates the cooperation resource area in a semi-competitive or dynamic manner, the node notifies the cooperation resource of the collaboration to the cooperation node. In addition, in a case where the cooperative resource area is allocated in a semi-static or dynamic manner, the processing of the resource allocation by the node may be: the node performs resource allocation according to the number of the first type of user equipment and the second type of user equipment and the service type. The size of the collaborative resource area is determined according to the resource allocation result, and the allocated resources of the collaborative resource area are identified after the resources of the collaborative resource area are allocated. In addition, in a case where the node allocates the cooperation resource area in a static manner, the method may further include: all nodes in the network allocating the same fixed resource as the cooperation resource area, and the allocated cooperation resource area is a resource area shared by all nodes. . Moreover, in the case where the node performs static resource allocation, the resources in the coordinated resource area allocated by the node are continuous or non-contiguous resources. In addition, after the node performs resource allocation, the method may further include: mapping only ports dedicated to the first type of user equipment in the cooperative resource area, and inserting pilots of the port according to the pilot pattern of the port. Optionally, the method may further include: in the cooperative resource area, when the first type of user equipment is at the coverage edge of the node and the interference of the first type of user equipment is below a minimum threshold, the user equipment is switched to the first a second type of user equipment, and the neighboring node of the node provides services for other near-end user equipments in the coverage area of the node on the resources of the user equipment; in the non-cooperative resource area, the second type of user equipment is in the node In the case of the coverage edge, and the second type of user equipment is higher than the maximum threshold or the neighboring node of the node has idle resources, the user equipment is converted into the first type of user equipment, and the node and the neighboring node cooperate in cooperation. The resource area provides services for the user equipment; wherein, the maximum threshold is greater than or equal to a minimum threshold. Preferably, the foregoing node is at least one of the following: a base station, a relay station, a radio frequency unit, and a cell. Preferably, the size of the resource corresponding to the coordinated resource area is an integer multiple of the size of the scheduling unit, or an integer multiple of the feedback sub-band, where an integer multiple of the size of the scheduling unit, or an integer multiple of the feedback sub-band is the time domain and frequency An integer multiple of the domain granularity. With the above technical solution of the present invention, by allocating independent resources for users who cooperate with multiple nodes, it is possible to reasonably allocate required resources for the cooperative users, and it is possible to avoid the cooperation between the cooperative users and the non-cooperative users (ie, the second type of user devices).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention provide an improved resource allocation method by which a node resource can be divided and resources are allocated to different users, so that the coordinated user can be reasonably allocated. Resources, enabling multi-point collaborative users and non-multi-point collaborative users, LTE and LTE-A users are simultaneously compatible within the node to optimize the working state of the system. The preferred embodiments of the present invention are described with reference to the accompanying drawings, and the preferred embodiments of the present invention are intended to illustrate and explain the invention. In the following description, numerous specific details are set forth However, it is apparent that the present invention may be practiced without these specific details. Further, various details may be obtained in the following embodiments and examples without departing from the spirit and scope of the appended claims. Make various combinations. Method Embodiments According to an embodiment of the present invention, a resource allocation method is provided, which is used for resource allocation in a case where: a first type of user equipment and a single _j having multi-node cooperation services under the same node, The second type of user equipment in the embodiment of the present invention may also be referred to as a multi-point cooperative user equipment or an LTE-A user equipment, and the second type of user equipment may also be referred to as a normal user equipment. FIG. 1 shows a processing flow of a resource allocation method according to an embodiment of a method according to the present invention. As shown in FIG. 1, the processing flow includes steps S102 and S104. Step S102: For the first type of user equipment, the node (for example, may be a Node B) allocates a dedicated collaborative resource area to it; in step S104, the node performs resource scheduling on the first type of user equipment in the coordinated resource area. In practical applications, the node can divide the resources that need to be allocated to obtain the cooperative resource area and the non-collaboration resource area. The area division of the resources to be allocated can also be understood as: dividing the resources that need to be allocated to ordinary users. To get the need for multi-point collaboration users (ie, The first type of user equipment is allocated resources (resources corresponding to the cooperation resource area), and the remaining resources are allocated as resources (the resources corresponding to the non-cooperative resource areas) of the ordinary users (the second type of user equipments). Optionally, when the node allocates the cooperation resource area to the first type of user equipment, the node may be in any one of a time division manner and a frequency division manner (the foregoing predetermined manner), contending, semi-striking, or dynamically The first type of user allocates a collaborative resource area. The time division mode means that the resources allocated to the first type of user equipment and the resources allocated to the second type of user equipment are located in different time slots or subframes, which is beneficial to reduce control overhead; the frequency division method refers to the first The resources allocated by one type of user equipment and the resources allocated to the second type of user equipment are located at different frequencies of the same time slot, and the scheduling in a frequency division manner is more real-time. In a practical application, if the predetermined mode is the time division mode, the node may allocate a blank subframe for the first type of user equipment for the resource call of the first type of user equipment, where the blank subframe is specifically set for the first type of user equipment. Subframes, and the number of blank subframes can also be configured according to the number of user equipments of the first type. Jt匕, from the above description, it can be seen that the node can be flexibly allocated according to the number of multi-node cooperative users (the number of first-class user equipments) or the usage of neighboring node resources through semi-contention or dynamic allocation. Resources, by semi-statically or dynamically allocating the cooperation zone resources, can allocate resources to the first type of user equipment more reasonably; and the manner of allocating the continuous resources of the cooperation zone to the first type of user equipment can be referred to as a centralized distribution mode. The manner in which the non-contiguous resources of the collaboration area are allocated to the first type of user equipment may be referred to as a distributed allocation method. Preferably, in the case that the node allocates the cooperation resource area in a semi-static or dynamic manner, the following processing may be performed:

1. When the node performs the division of the coordinated resource area and the non-cooperative resource area, the bandwidth of the idle resource of the neighboring node of the node is preferentially selected as the ten resource area. 2. The priority of the node to allocate the resource zone to the first type of user equipment is higher than the priority of the node to allocate the resource zone to the second type of user equipment, that is, the priority is allocated to the first type of user equipment.

3. The node notifies the collaboration node of the collaboration resource of the collaboration.

4. The processing of resource allocation by the node is specifically as follows: The node allocates resources according to the number of the first type of user equipment and the second type of user equipment and the type of service, and determines the cooperation resources according to the resource allocation result. The size of the source area, and the allocated resources of the collaborative resource area are identified after the resources of the collaborative resource area are allocated. On the other hand, in the case where the node allocates the cooperative resource area in a static manner, the following processing may be performed: 1. According to the pre-planning of the network, all nodes in the network (including the above-mentioned nodes) are pre-allocated with the same fixed resource. As a collaborative resource area, and the allocated collaborative resource area should be a resource area shared by all nodes as much as possible, thereby ensuring effective multi-point cooperation.

2. The resources in the collaborative resource area allocated by the node are continuous or non-contiguous resources. After the node performs resource allocation, only the ports dedicated to the first type of user equipment are mapped in the cooperative resource area, and the pilots of the port are inserted according to the pilot pattern of the port. In addition, in the cooperative resource area, when the first type of user equipment is at the coverage edge of the node and the interference of the first type of user equipment is below a minimum threshold, the user equipment is switched to the second type of user equipment, and the node is The neighboring node provides services for other near-end user equipments in the coverage area of the node on the resources of the user equipment; in the non-cooperative resource area, the second type of user equipment is at the coverage edge of the node, and the second type If the interference of the user equipment is higher than the maximum threshold or the neighboring node of the node has an idle resource, the user equipment is converted into the first type of user equipment, and the node and the neighboring node cooperate to provide the monthly service to the user equipment in the cooperation resource area; , the maximum threshold is greater than or equal to the minimum threshold. Preferably, since resources of the cooperation area are mainly used to provide services for the first type of user equipment, signals and data can be transmitted with greater power in the cooperation area; and neighboring cells can be compared on the same resource. Small power is sent, which can be used to schedule near-end users. Preferably, the size of the resource corresponding to the coordinated resource area is an integer multiple of the size of the scheduling unit, or an integer multiple of the feedback sub-band. It should be noted that the manner of resource division and resource allocation for the second type of user equipment (ie, non-multipoint coordinated users) may be implemented according to related technologies, and is not mentioned here. Optionally, after performing resource allocation, the first type of user equipment and the second type of user equipment feed back at least one of the following information to the node according to a predetermined manner: channel quality information (CQI for short), Precoding matrix index (recoding matrix index, abbreviation It is PMI) and rank information (referred to as RI). In a specific implementation process, the foregoing node may be any one of a base station (BS), a relay station (RS), a remote radio unit (RRU), and a cell, and may also be any network element that participates in cooperation, and It is not limited to the case listed in the embodiment. Through the method provided in this embodiment, a reasonable network resource can be allocated for the multi-point cooperative user and the non-multi-point collaborative user. Example 1: Frequency Division Mode FIG. 2 is a resource of a normal user (a second type of user equipment) and a multipoint coordinated user (a first type of user equipment) in a frequency division manner according to a resource allocation method according to an embodiment of the method of the present invention. A schematic diagram of the allocation mode, as shown in FIG. 2, divides the frequency resources of the node into a common user service area and a coordination area (ie, the above-mentioned collaborative resource area), and the coordinated area occupies a dedicated frequency resource to provide network resources for the coordinated users. The common user service area (non-cooperative resource area) provides frequency resources for ordinary users who do not cooperate in multiple points, and the multi-point cooperative users and ordinary users use resources on different frequency resources in the same time slot. The process of allocating the frequency resources of the node in the frequency division manner includes the following steps: Step 1: The serving cell divides a certain frequency resource (that is, the foregoing collaborative resource area) for the collaboration user (the first type of user equipment) Corresponding to step S102) in FIG. 1, the multi-point coordinated user is scheduled within the resource (corresponding to step S104 in FIG. 1), and power boosting can be performed in the cooperation area to expand coverage. Scope, as shown in the shaded part of Figure 2, the resource size is configured by the serving cell in a static/semi-static or dynamic manner; Step 2: The serving cell is based on the feedback information of the user equipment (User Equipment, UE for short), first The first type of user equipment that needs to perform coordinated multi-point transmission is scheduled in the collaborative resource; Step 3: The serving cell performs scheduling and resources on the resources of the non-cooperative user (ie, the second type of user equipment) of the ordinary user. Allocation; if the collaborative resources are not fully utilized, the serving cell may also use the remaining resources according to the utilization of the collaborative resources. Source type assigned to the second user device; step 4, if the resource allocation semi-static or dynamic manner, the collaborative resources serving cell area and uncoordinated resource allocation resource region notify the user of the cell; The Channel Quality Indication (CQI), the Precoding Matrix Indicator (PMI), and the rank indication are used because of the difference between the first type of user equipment and the second type of user equipment. The Rank Indication (referred to as RI) feedback can be performed as follows: The service node specifies the feedback subband width and granularity of the user, and the user only feeds back within the specified resource. For example, for the first type of user equipment, the service node specifies its feedback subband as a dedicated resource area (collaboration resource area) of the cooperative user, and the second type of user equipment feeds back in other subbands; when full bandwidth scheduling is required, the user The full bandwidth feedback can be used, and the service node separates the required CQI, PMI and RI information according to the difference between the cooperative resource and the non-cooperative resource. Example 2: Time-division mode FIG. 3 is a schematic diagram of a resource allocation manner of a common user and a multi-point cooperative user in a time division manner according to the resource allocation method according to the method embodiment of the present invention. As shown in FIG. 3, the time resource of the node may be used. It is divided into non-cooperative resource areas (general users (second type user equipment) service areas and collaborative resource areas), collaborative resource areas provide dedicated time resources for multi-point collaborative users, and non-cooperative resource areas provide for second-class user equipment. The time resource, and the first type of user equipment and the second type of user equipment use resources on different time slot resources of the same frequency. The process of allocating the actual resources of the node in a time division manner includes the following steps: Step 1: The serving cell allocates a certain time resource for the collaboration user (ie, the first type of user equipment) (corresponding to the steps in FIG. 1) S102), in a practical application, the serving cell may also allocate a blank subframe for the collaboration user equipment to perform resource calling, where the blank subframe is a subframe specially set for the collaboration user equipment, and is blank. The number of subframes can also be configured according to the number of cooperative user equipments. And scheduling the first type of user equipment in the resource (corresponding to step S104 in FIG. 1), the user scheduled in the part of the resource may perform power boosting to expand the coverage, as shown in the shaded part of FIG. The configuration of the resource size is allocated by the monthly service cell contention/semi-contention or dynamic; Step 2: The serving cell first performs scheduling and allocation in the coordinated resource for the UE that needs to perform coordinated multi-point transmission according to the feedback information of the UE. Step 3: The serving cell performs scheduling and resource allocation in the non-cooperative resource area for the common user (ie, the second type of user equipment); if the cooperative resource is not fully utilized, the serving cell according to the utilization of the resource in the collaborative resource area, It is also possible to allocate the remaining resources to ordinary users; Step 4: If the configuration of the resource is in a semi-static or dynamic manner, the serving cell notifies the user of the community of the resource allocation of the coordinated resource area and the non-cooperative resource area. At this time, since resource allocation is performed in a time division manner, the feedback operations of CQI, ΡΜΙ, and RI can be performed in a manner specified by the service node, and no additional operations are required. 2 and 3 above show the case where resource allocation is performed in a frequency division manner and a time division manner. Since both frequency reuse technology and CoMP technology can be used to solve the ICIC problem in the cell, CoMP technology can better solve the ICIC problem, but at the cost of wasting two resources together for one user, the node can further The technology is used in combination to determine whether to serve the current user in a cooperative mode or a soft frequency reuse mode according to the interference level of the target user. When the node supports the CoMP mode, it can be determined according to the interference situation and the resource usage situation that the user is served in a cooperative manner or in a soft frequency multiplexing manner, and the real-time switching can be performed according to the measurement result. The handover can be divided into two cases: Case 1: When the cell edge user interference is weak (such as when the distance between the user and the neighboring cell and the distance between the service and the area is large), the soft frequency multiplexing mode is adopted; When the measured strength is greater than the threshold or when neighboring nodes are idle on the same resource, switch to the cooperative mode and cooperate to serve the edge user. The switching of the above two cases will be described in detail below. 4 is a schematic diagram of resource allocation in an adaptive handover process of multi-point cooperation and frequency reuse in a cooperative resource region according to a resource allocation method according to an embodiment of the method of the present invention, as shown in FIG. 4, different nodes ( Cell #1 and Cell #2 are respectively assigned different resources as cooperative resource regions. As shown in the shaded portion in FIG. 4, when Cell #1 is frequency-multiplexed with neighboring cell Cell #2, node Cell #1 will An edge user of the cell (for example, UE1, also referred to as a remote user) is scheduled to be in the coordinated resource area and transmitted with a large power; in the adjacent cell Cell #2, the near-end user (for example, UE2) is scheduled. To the frequency resource corresponding to the ten working resource area of Cell #1, and send it with less power; when Cell # 1 and Cell #2 are in the cooperation mode as 'j, the area edge user (for example, user 1 moves) Go to the location where the cell 1 and the cell 2 are quite different.) During the month, Baye Cell #1 and cell

#2 On the same resource, the target user will be in the same way. 5 is a schematic diagram of adaptive handover of multi-point cooperation and frequency reuse in a cooperative resource region according to a resource allocation method according to an embodiment of the method of the present invention, as shown in FIG. 5, when a node (for example, Cell #l) or When the terminal (for example, UE1) detects that the interference is large, for example, when the interference is greater than a given threshold 5 ₂ , or when the neighboring node Cell #2 is idle, the neighboring node Cell #2 is in the same resource. Collaborate with the node Cell #1 to jointly provide services for the user UE1. At this time, Cell #1 and Cell #2 are switched from the frequency reuse mode to the cooperative mode. As shown in FIG. 5, in the soft frequency reuse mode, only Cell #1 provides resources for UE1. After Cell #1 and Cell #2 switch to cooperative mode, Cell #1 and Cell #2 simultaneously provide resources for UE1. When the ratio of the different nodes Cell #1 and Cell #2 to the target user is less than the given threshold β, the mode is switched back to the soft frequency reuse mode. When the interference of the neighboring cell is less than S _t , the node can call the user to the ordinary Resource area. Moreover, when the neighboring node Cell #2 is in the same time slot and the load is large, while providing service to the terminal UE1, the UE2 of the cell may be provided with the monthly service by using the space division multiple access method. For example, using closed-loop precoding or beam forming, UE2 is within the zero limit of UE1's interference. In a specific implementation process, in the downlink, the UE may measure the interference situation of each neighboring node in the downlink, and feed back to the serving node, and the serving node compares with the threshold according to the feedback result, if the strength of the dry 4 is greater than a threshold or The feedback result is in the same time slot as the threshold, and the neighboring node is idle in the same resource, then switches to the cooperative mode, and the neighboring node and the serving node cooperate to serve the target user; in the uplink, the serving node measures the uplink signal. The interference condition, and compared with the threshold, if the interference is greater than the threshold, or the neighboring node is idle at the same resource, the uplink signal is received in a cooperative mode. In summary, with the technical solution of the present invention, a multi-node cooperative user allocates independent resources (ie, divides resources into regions), and can reasonably allocate required resources for collaborative users, which can avoid collaboration users and non-collaboration. The difference between the equivalent channel existing between the user (ie, the second type of user equipment mentioned above) affects the scheduling of the user, and can also avoid the situation that multiple sets of pilots exist at the same time, which is beneficial to the scheduling of the user in the full bandwidth; In addition, by adaptively switching between the collaborative area and the non-cooperative area, the system can be guaranteed to work optimally. The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes can be made to the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and scope of the present invention are intended to be included within the scope of the present invention.
