Embodiment 1
This embodiment provides a resource allocation method that can be applied to wireless communication systems such as CDMA, WCDMA, FDD LTE, where the bandwidth resources are symmetric. First, the base station acquires uplink resources and downlink resources required for the service of the terminal. If the required uplink resources exceed the required downlink resources, the base station reassigns some of the downlink resources as uplink resources or the required downlink resources are needed The base station reallocates some of the uplink resources as downlink resources, so that the required uplink bandwidth resources and the required downlink bandwidth Achieving the purpose of performing allocations due to resource asymmetry. Further, the base station transmits information about the adjusted resource to the terminal, so that the terminal performs service transmission according to the adjusted resource.

  In the present embodiment, an example in which an FDD LTE base station is an execution subject is used for explanation.

  FIG. 1 shows a schematic flowchart of a resource allocation method according to this embodiment.

  Step 101: Obtain uplink resources and downlink resources required for the service of the terminal, and among the required uplink resources and required resources, the larger one is the resource to be expanded, The smaller is the resource to be reduced.

  Optionally, the uplink resource may be an uplink bandwidth resource and the downlink resource may be a downlink bandwidth resource.

  In this embodiment, the base station can acquire the uplink resource and the downlink resource required for the service of the terminal through the statistics. The uplink and downlink resource statistics required for the terminal service are the uplink resource and downlink resource statistics required for the terminal service during a preset time interval. May be. For example, statistics of uplink bandwidth resources and downlink bandwidth resources required for the service of the terminal for one month are collected, and the uplink bandwidth resources and downlink bandwidth resources are compared to determine which requirements Determine if is greater. Of course, in practical applications, the base station can further obtain uplink and downlink resources required for the service of the terminal by using statistics collected by another entity.

  Step 102: Add some of the resources to be reduced to the resources to be expanded.

  Specifically, when the uplink resource required for the terminal service exceeds the downlink resource required for the terminal service, the resource to be expanded is the uplink resource, and the resource to be reduced Is a downlink resource, and if the downlink resource required for the terminal service exceeds the uplink resource required for the terminal service, the resource to be expanded is the downlink resource and is reduced The resource to be used is an uplink resource. Preferably, some of the resources to be reduced are expanded according to a ratio of uplink resources required for the terminal service to downlink resources required for the terminal service collected by statistics. Can be added to the resource to be. For example, if the uplink resources required for the terminal service exceeds the downlink resources required for the terminal service, some of the downlink resources are required for the terminal service collected by statistics. In accordance with the ratio of the uplink resource to the downlink resource required for the terminal service, the downlink resource required for the terminal service is reassigned as the uplink resource and is required for the terminal service. Part of the uplink bandwidth according to the ratio of the uplink resources required for the terminal service to the downlink resources required for the terminal service, collected by statistics. Reassigned as a downlink resource

  When the uplink resource required for the service to be processed is equal to the downlink resource required for the service to be processed, the current resource is neither wasted nor uplink resource So it can be known that it does not need to be adjusted.

  Step 103: Distribute a resource configuration message to the terminal, wherein the resource configuration message includes information on the uplink resources and downlink resources to be adjusted, so that the terminal can perform service transmission, uplink resources and downlink to be adjusted. Execute according to the link resource.

  The base station generates a corresponding resource configuration message according to the adjusted uplink resource and downlink resource, and distributes the corresponding resource configuration message to the terminal. The terminal obtains the uplink resources and downlink resources to be adjusted according to the resource configuration message, and performs service transmission according to the uplink resources and downlink resources to be adjusted.

  According to the resource allocation method of the present embodiment, first, statistics of uplink resources and downlink resources required for the service of the terminal are collected, and the required uplink resources are determined as the required downlink. When exceeding resources, some of the downlink resources are reallocated as uplink resources, or when the required downlink resources exceed the required uplink resources, some of the uplink resources are Information about resources that are reallocated and adjusted as downlink resources is transmitted to the terminal, so that the terminal performs service transmission according to the information about the adjusted resource, thereby enabling a conventional wireless communication system Uplink resources required in To be caused by an imbalance between the downlink resources needed to solve the problem of waste of uplink resources or downlink resources.

Embodiment 2
The present embodiment provides a resource allocation method based on the first embodiment.

  Step 201: Obtain uplink resources and downlink resources required for the service of the terminal, where the larger of the required uplink resources and required downlink resources should be expanded A resource is smaller and a resource to be reduced.

  Optionally, the uplink resource may be an uplink bandwidth resource and the downlink resource may be a downlink bandwidth resource.

  The specific content of this step is the same as that of step 101 and will not be described again here.

  Step 202: Add some of the resources to be reduced to the resources to be expanded according to the ratio of the uplink resources required for the terminal services to the downlink resources required for the terminal services.

  Prior to allocation, both the resource to be reduced and the resource to be expanded are S. [(Q−P) / (in the resource to be reduced when the ratio of the resource to be reduced to the resource to be extended required is P: Q and P <Q. Q + P)] × S is added to the resource to be expanded.

  For example, the uplink bandwidth resource is 5M, the downlink bandwidth resource is 5M, and the ratio of the required uplink bandwidth resource to the required downlink bandwidth resource is 2: 3. When the 1M bandwidth resource of the uplink bandwidth resource can be reassigned as the downlink bandwidth resource, and thus the adjusted downlink bandwidth of the adjusted uplink bandwidth resource The ratio to resources is 2: 3.

Specifically, adding a portion of the bandwidth resource of the resource to be reduced to the resource to be expanded
Including adding a part of the frequency band resource of the resource to be reduced to the resource to be expanded, or adding a part of the time slot resource of the resource to be reduced to the resource to be expanded.

  The frequency band is a frequency range from the highest frequency at which a signal can be transmitted to the lowest frequency at which the signal can be transmitted, and the frequency band may include a plurality of frequency spectra. Preferably, the frequency band resource at the edge of the bandwidth to be reduced is added to the resource to be expanded. This is because in conventional wireless communication systems, the frequency band received or transmitted by the receiver / transmitter is determined by using the center frequency and bandwidth. If the central frequency band resource of the bandwidth to be reduced is added to the bandwidth resource to be expanded, the original bandwidth resource to be reduced may be divided into two segments, in this case 2 Two receivers / transmitters are required. However, such problems are avoided if frequency band resources close to the edge of the bandwidth to be reduced are added to the resources to be expanded. One frequency spectrum close to the edge of the bandwidth resource to be reduced can be added to the resource to be expanded, or the two frequency spectra can be reassigned, and the frequency spectrum Note that the number can be set according to actual needs.

  When the base station determines that the uplink resource required for the terminal service exceeds the downlink resource required for the terminal service, the base station uses the downlink frequency band resource originally used as the downlink resource. A portion is reassigned as an uplink resource, where a portion of the downlink frequency band resource is referred to as a second uplink resource, and the original uplink frequency band resource is the first uplink frequency Used as a bandwidth resource. FIG. 2A shows a schematic diagram of using a frequency band resource close to two edges of a downlink frequency band resource as an uplink frequency band.

  Similarly, when the base station determines that the downlink bandwidth resource required for the service to be processed exceeds the uplink bandwidth resource required for the service to be processed, the uplink bandwidth A part of the uplink frequency band resource of the resource is reallocated as a downlink bandwidth resource, where a part of the downlink frequency band resource is called a second downlink bandwidth resource and is The link frequency band is a first downlink frequency band. FIG. 2B shows a schematic diagram of reallocating and using frequency band resources proximate to the two edges of the uplink frequency band as downlink frequency bands. The time slot resource represents a frequency resource actually occupied by the physical layer. First, the entire bandwidth is partitioned into various frequency bands, and then various time slot resources are allocated to users on the same frequency band, and the time slot resources occupied by each user are channels.

  When the base station determines that the required uplink bandwidth resource exceeds the required downlink bandwidth resource, part of the downlink time slot resource that was originally used as the downlink bandwidth resource Are used as uplink time slot resources, where a portion of the downlink time slot resource is referred to as a second uplink bandwidth resource, and the original uplink bandwidth resource is the first uplink resource. Used as a bandwidth resource. FIG. 3A shows a schematic diagram of using part of the downlink time slot resource of the downlink frequency band as the uplink time slot resource. Similarly, when the base station determines that the required downlink bandwidth resource exceeds the required uplink bandwidth resource, the uplink time slot resource originally used as the uplink bandwidth resource Is used as a downlink time slot bandwidth resource, a portion of the uplink time slot resource is referred to as a second downlink bandwidth resource, and the original downlink bandwidth resource is the first Called downlink bandwidth resource. FIG. 3B shows a schematic diagram of using part of the uplink time slot resource of the uplink bandwidth resource as the downlink time slot resource.

  Step 203: Distribute a resource configuration message to the terminal, wherein the resource configuration message includes information on the uplink resources and downlink resources to be adjusted, so that the terminal can perform service transmission, uplink resources and downlink to be adjusted. Execute according to the link resource.

  The base station can notify the terminal of the resource configuration message by using the broadcast message, and the resource configuration message is specifically the band of the first uplink frequency band or the first downlink frequency band. Width, the center frequency of the first frequency band, the corresponding second uplink frequency band or the bandwidth of the second downlink frequency band, and the center frequency of the second frequency band.

  If the required uplink bandwidth resource exceeds the required downlink bandwidth resource, the base station may communicate with the terminal through a PDCCH (Physical Downlink Control Channel) in the downlink frequency band. The resource configuration message is sent to the terminal. After receiving the resource configuration message, the terminal transmits an uplink control signal to the base station by using only the first uplink bandwidth. The base station transmits a resource configuration message by using a downlink frequency band, and uplink scheduling information includes the number of RBs (resource blocks, radio resource blocks), RB positions, MCS (modulation coding scheme, (Modulation and Coding Scheme) order and uplink frequency band information. The terminal performs data transmission according to the uplink scheduling information at a specified RB position and in a specified MCS order on a specified frequency band. If the required downlink bandwidth resource exceeds the required uplink bandwidth resource, the base station sends a resource configuration message to the terminal on the first downlink frequency band, and the base station Distributes uplink scheduling information by using only the first downlink frequency band, and the uplink scheduling information includes the number of RBs (wireless resource blocks, resource blocks), RB positions, MCS (wireless resource blocks). , Resource block) order, and uplink frequency band information. When the base station schedules the data service, the control signal can be delivered through the PDDCH in the first downlink frequency band or can be delivered through the PDDCH in the second downlink frequency band. it can.

  According to the resource allocation method of this embodiment, when the required uplink resource exceeds the required downlink resource, a part of the frequency band resource of the downlink resource is reallocated as the uplink resource, or When the required downlink resources exceed the required uplink resources, a portion of the uplink bandwidth frequency band resources are reallocated as downlink resources, thereby enabling in conventional wireless communication systems Resolve the problem of wasting uplink resources or downlink resources caused by imbalance between required uplink resources and required downlink resources.

Embodiment 1
This embodiment provides a resource allocation method that can be applied to wireless communication systems such as CDMA, WCDMA, FDD LTE, where the bandwidth resources are symmetric. First, the base station acquires uplink resources and downlink resources required for the service of the terminal. If the required uplink resources exceed the required downlink resources, the base station reassigns some of the downlink resources as uplink resources or the required downlink resources are needed The base station reallocates some of the uplink resources as downlink resources, so that the required uplink bandwidth resources and the required downlink bandwidth Achieving the purpose of performing allocations due to resource asymmetry. Further, the base station transmits information about the adjusted resource to the terminal, so that the terminal performs service transmission according to the adjusted resource.

  In the present embodiment, an example in which an FDD LTE base station is an execution subject is used for explanation.

  FIG. 1 shows a schematic flowchart of a resource allocation method according to this embodiment.

Step 101: Obtain uplink resources and downlink resources required for the service of the terminal, and the larger of the required uplink resources and the required downlink resources are resources to be expanded. Yes, smaller ones are resources to be reduced.

Optionally, the uplink resource may be an uplink bandwidth resource,
The downlink resource may be a downlink bandwidth resource.

  In this embodiment, the base station can acquire the uplink resource and the downlink resource required for the service of the terminal through the statistics. The uplink and downlink resource statistics required for the terminal service are the uplink resource and downlink resource statistics required for the terminal service during a preset time interval. May be. For example, statistics of uplink bandwidth resources and downlink bandwidth resources required for the service of the terminal for one month are collected, and the uplink bandwidth resources and downlink bandwidth resources are compared to determine which requirements Determine if is greater. Of course, in practical applications, the base station can further obtain uplink and downlink resources required for the service of the terminal by using statistics collected by another entity.

  Step 102: Add some of the resources to be reduced to the resources to be expanded.

Specifically, when the uplink resource required for the terminal service exceeds the downlink resource required for the terminal service, the resource to be expanded is the uplink resource, and the resource to be reduced Is a downlink resource, and if the downlink resource required for the terminal service exceeds the uplink resource required for the terminal service, the resource to be expanded is the downlink resource and is reduced The resource to be used is an uplink resource. Preferably, some of the resources to be reduced are according to a ratio of uplink resources required for the terminal service to downlink resources required for the terminal service, collected by statistics.
Can be added to resources to be expanded. For example, if the uplink resources required for the terminal service exceeds the downlink resources required for the terminal service, some of the downlink resources are required for the terminal service collected by statistics. In accordance with the ratio of the uplink resource to the downlink resource required for the terminal service, the downlink resource required for the terminal service is reassigned as the uplink resource and is required for the terminal service. Part of the uplink bandwidth according to the ratio of the uplink resources required for the terminal service to the downlink resources required for the terminal service, collected by statistics. Reassigned as a downlink resource

  When the uplink resource required for the service to be processed is equal to the downlink resource required for the service to be processed, the current resource is neither wasted nor uplink resource So it can be known that it does not need to be adjusted.

  Step 103: Distribute a resource configuration message to the terminal, wherein the resource configuration message includes information on the uplink resources and downlink resources to be adjusted, so that the terminal can perform service transmission, uplink resources and downlink to be adjusted. Execute according to the link resource.

  The base station generates a corresponding resource configuration message according to the adjusted uplink resource and downlink resource, and distributes the corresponding resource configuration message to the terminal. The terminal obtains the uplink resources and downlink resources to be adjusted according to the resource configuration message, and performs service transmission according to the uplink resources and downlink resources to be adjusted.

  According to the resource allocation method of the present embodiment, first, statistics of uplink resources and downlink resources required for the service of the terminal are collected, and the required uplink resources are determined as the required downlink. When exceeding resources, some of the downlink resources are reallocated as uplink resources, or when the required downlink resources exceed the required uplink resources, some of the uplink resources are Information about resources that are reallocated and adjusted as downlink resources is transmitted to the terminal, so that the terminal performs service transmission according to the information about the adjusted resource, thereby enabling a conventional wireless communication system Uplink resources required in To be caused by an imbalance between the downlink resources needed to solve the problem of waste of uplink resources or downlink resources.

Embodiment 2
The present embodiment provides a resource allocation method based on the first embodiment.

Step 201: Obtain uplink and downlink resources required for the service of the terminal, where the larger of the required uplink resources and the required downlink resources are expanded. Resources to be reduced, and smaller ones to be reduced.

Optionally, the uplink resource may be an uplink bandwidth resource,
The downlink resource may be a downlink bandwidth resource.

  The specific content of this step is the same as that of step 101 and will not be described again here.

  Step 202: Add some of the resources to be reduced to the resources to be expanded according to the ratio of the uplink resources required for the terminal services to the downlink resources required for the terminal services.

Prior to allocation, both the resource to be reduced and the resource to be expanded are S.
[(Q−P) / (in the resource to be reduced when the ratio of the resource to be reduced to the resource to be extended required is P: Q and P <Q. Q + P)] × S is added to the resource to be expanded.

  For example, the uplink bandwidth resource is 5M, the downlink bandwidth resource is 5M, and the ratio of the required uplink bandwidth resource to the required downlink bandwidth resource is 2: 3. When the 1M bandwidth resource of the uplink bandwidth resource can be reassigned as the downlink bandwidth resource, and thus the adjusted downlink bandwidth of the adjusted uplink bandwidth resource The ratio to resources is 2: 3.

Specifically, adding a portion of the bandwidth resource of the resource to be reduced to the resource to be expanded
Including adding a part of the frequency band resource of the resource to be reduced to the resource to be expanded, or adding a part of the time slot resource of the resource to be reduced to the resource to be expanded.

  The frequency band is a frequency range from the highest frequency at which a signal can be transmitted to the lowest frequency at which the signal can be transmitted, and the frequency band may include a plurality of frequency spectra. Preferably, the frequency band resource at the edge of the bandwidth to be reduced is added to the resource to be expanded. This is because in conventional wireless communication systems, the frequency band received or transmitted by the receiver / transmitter is determined by using the center frequency and bandwidth. If the central frequency band resource of the bandwidth to be reduced is added to the bandwidth resource to be expanded, the original bandwidth resource to be reduced may be divided into two segments, in this case 2 Two receivers / transmitters are required. However, such problems are avoided if frequency band resources close to the edge of the bandwidth to be reduced are added to the resources to be expanded. One frequency spectrum close to the edge of the bandwidth resource to be reduced can be added to the resource to be expanded, or the two frequency spectra can be reassigned, and the frequency spectrum Note that the number can be set according to actual needs.

  When the base station determines that the uplink resource required for the terminal service exceeds the downlink resource required for the terminal service, the base station uses the downlink frequency band resource originally used as the downlink resource. A portion is reassigned as an uplink resource, where a portion of the downlink frequency band resource is referred to as a second uplink resource, and the original uplink frequency band resource is the first uplink frequency Used as a bandwidth resource. FIG. 2A shows a schematic diagram of using a frequency band resource close to two edges of a downlink frequency band resource as an uplink frequency band.

  Similarly, when the base station determines that the downlink bandwidth resource required for the service to be processed exceeds the uplink bandwidth resource required for the service to be processed, the uplink bandwidth A part of the uplink frequency band resource of the resource is reallocated as a downlink bandwidth resource, where a part of the downlink frequency band resource is called a second downlink bandwidth resource and is The link frequency band is a first downlink frequency band. FIG. 2B shows a schematic diagram of reallocating and using frequency band resources proximate to the two edges of the uplink frequency band as downlink frequency bands. The time slot resource represents a frequency resource actually occupied by the physical layer. First, the entire bandwidth is partitioned into various frequency bands, and then various time slot resources are allocated to users on the same frequency band, and the time slot resources occupied by each user are channels.

When the base station determines that the required uplink bandwidth resource exceeds the required downlink bandwidth resource, part of the downlink time slot resource that was originally used as the downlink bandwidth resource Are used as uplink time slot resources, where a portion of the downlink time slot resource is referred to as a second uplink bandwidth resource, and the original uplink bandwidth resource is the first uplink resource. Used as a bandwidth resource. Figure 3 B shows a schematic view of using a part of the downlink timeslot resources of the downlink frequency band as the uplink slot resource. Similarly, when the base station determines that the required downlink bandwidth resource exceeds the required uplink bandwidth resource, the uplink time slot resource originally used as the uplink bandwidth resource Is used as a downlink time slot bandwidth resource, a portion of the uplink time slot resource is referred to as a second downlink bandwidth resource, and the original downlink bandwidth resource is the first Called downlink bandwidth resource. Figure 3 A shows a schematic diagram of using a portion of the uplink slot resource for uplink bandwidth resource as downlink timeslot resources.

  Step 203: Distribute a resource configuration message to the terminal, wherein the resource configuration message includes information on the uplink resources and downlink resources to be adjusted, so that the terminal can perform service transmission, uplink resources and downlink to be adjusted. Execute according to the link resource.

  The base station can notify the terminal of the resource configuration message by using the broadcast message, and the resource configuration message is specifically the band of the first uplink frequency band or the first downlink frequency band. Width, the center frequency of the first frequency band, the corresponding second uplink frequency band or the bandwidth of the second downlink frequency band, and the center frequency of the second frequency band.

If the required uplink bandwidth resource exceeds the required downlink bandwidth resource, the base station may communicate with the terminal through a PDCCH (Physical Downlink Control Channel) in the downlink frequency band. The resource configuration message is sent to the terminal. After receiving the resource configuration message, the terminal transmits an uplink control signal to the base station by using only the first uplink bandwidth. Base station by using a downlink frequency band, and transmits the resource configuration message and the uplink scheduling information, RB (resource block, Resource Block) number of, RB position, MCS (modulation and coding scheme, Modulation and Coding Scheme) order and uplink frequency band information. The terminal performs data transmission according to the uplink scheduling information at a specified RB position and in a specified MCS order on a specified frequency band. If the required downlink bandwidth resource exceeds the required uplink bandwidth resource, the base station sends a resource configuration message to the terminal on the first downlink frequency band, and the base station , by using only the first downlink frequency band, and delivers the uplink scheduling information, uplink scheduling information includes the number of RB, RB location, MCS order, and the uplink frequency band information. When the base station schedules the data service, the control signal can be delivered through the PDDCH in the first downlink frequency band or can be delivered through the PDDCH in the second downlink frequency band. it can.

  According to the resource allocation method of this embodiment, when the required uplink resource exceeds the required downlink resource, a part of the frequency band resource of the downlink resource is reallocated as the uplink resource, or When the required downlink resources exceed the required uplink resources, a portion of the uplink bandwidth frequency band resources are reallocated as downlink resources, thereby enabling in conventional wireless communication systems Resolve the problem of wasting uplink resources or downlink resources caused by imbalance between required uplink resources and required downlink resources.
