The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. The embodiments are a part of the embodiments of the invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

Embodiment 1 This embodiment provides a resource allocation method, which is applicable to a wireless communication system with symmetric bandwidth resources, such as CDMA, WCDMA or FDD LTE. First, the base station acquires the uplink resource and the required downlink resource required by the terminal service. If the required uplink resource is greater than the required downlink resource, the base station adjusts some resources from the downlink resource as the uplink resource; or if the required downlink is required If the resource is larger than the required uplink resource, the base station adjusts part of the resource from the uplink resource as the downlink resource, so as to achieve the purpose of allocating according to the required uplink and downlink bandwidth resources. Further, the base station sends the adjusted resource information to the terminal, so that the terminal performs the transmission of the service according to the adjusted resource.

This embodiment is described by using a base station in FDD LTE as an execution subject. As shown in FIG. 1, it is a schematic flowchart of a method for allocating resources according to the present embodiment. Step 101: Obtain the uplink resource and the required downlink resource required by the terminal service, and the larger one of the required uplink resource and the required resource is the resource to be added, and the smaller one 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 obtain the uplink resource and the required downlink resource required by the terminal service by using the statistics, and the uplink resource and the required downlink resource required for the terminal service can be the terminal in the preset time period. Statistics on the uplink resources and required downlink resources required by the service. For example, the uplink bandwidth resources and the required downlink bandwidth resources required for terminal services in one month are counted, and which needs are larger. Of course, in actual applications, the base station can also obtain uplink resources and required downlink resources required by the terminal service by using statistics of other entities. Step 102: Adjust some resources from the resources to be reduced to the resources to be added. Specifically, if the uplink resource required by the terminal service is greater than the downlink resource, the resource to be added is the uplink resource, and the resource to be reduced is the downlink resource; if the downlink resource required by the terminal service is greater than the uplink resource, the to-be-added The resource is a downlink resource, and the resource to be reduced is an uplink resource. Preferably, some resources are adjusted from the resources to be reduced to the resources to be added according to the ratio of the uplink resources required by the terminal services to the required downlink resources. For example, if the uplink resource required by the terminal service is larger than the downlink resource, the part of the resource is adjusted as the uplink resource from the downlink resource according to the ratio of the uplink resource and the required downlink resource required by the terminal service; If the downlink resource is larger than the uplink resource, the part of the resource is adjusted as the downlink resource from the uplink bandwidth according to the ratio of the uplink resource and the required downlink resource required by the terminal service. It is conceivable that when the uplink resource required for the service to be processed is equal to the required downlink resource, since there is no problem of waste of uplink or downlink resources, the current resource is not adjusted. Step 103: The resource configuration message is sent to the terminal, where the resource configuration message includes the information of the adjusted uplink resource and the downlink resource, so that the terminal performs the adjustment according to the adjusted uplink resource and the downlink resource resource configuration message. The transmission of business. The base station generates a corresponding resource configuration message according to the adjusted uplink resource and the downlink resource resource, and sends the corresponding resource configuration message to the terminal. The terminal obtains the adjusted uplink resource and the downlink resource according to the resource configuration message, and performs the service transmission according to the adjusted uplink resource and the downlink resource.

According to the resource allocation method of the embodiment, the uplink resource and the downlink resource required for the terminal service are first counted. When the required uplink resource is greater than the downlink resource, some resources are adjusted from the downlink resource as the uplink resource, or when If the required downlink resource is greater than the uplink resource, the part of the resource is used as the downlink resource, and the adjusted resource information is sent to the terminal, and the terminal performs the service transmission according to the adjusted resource information, thereby solving the existing Uplink resources or under the imbalance of uplink resources and downlink resources required in the wireless communication system The problem of wasting resources.

Embodiment 2 This embodiment provides a resource allocation method based on Embodiment 1. Step 201: Acquire an uplink resource and a required downlink resource required by the terminal service, where a larger one of the required uplink resource and the required downlink resource is a resource to be added, and a smaller one is a resource to be reduced. .

The specific content of this step is the same as step 101, and will not be described here. Step 202: Adjust, according to the ratio of the uplink resource to the required downlink resource required by the terminal service, a part of the resource to be added to the resource to be added. Before the adjustment, the resources to be reduced and the resources to be added are both S, when the ratio of the required resources to be reduced to the required resources to be added is P: Q and when P < Q, the resources to be reduced Adjust [(QP) / ( Q+P ) ] XS to add resources to be added.

For example, the uplink bandwidth resource is 5M, and the downlink bandwidth resource is 5M. When the ratio of the required uplink bandwidth resource to the required downlink bandwidth resource is 2:3, the 1M bandwidth resource can be adjusted from the uplink bandwidth resource to the downlink bandwidth resource. Thus, the ratio of the adjusted uplink bandwidth resource to the adjusted downlink bandwidth resource is 2:3.

The adjusting the part of the bandwidth resource from the resource to be reduced to the resource to be added includes: adjusting a part of the resource from the resource to be reduced to the resource to be added; or adjusting from the resource to be reduced. Part of the time slot resource is given to the resource to be added. The frequency band is the frequency range between the highest frequency of the signal that is allowed to be transmitted and the lowest frequency of the signal that is allowed to be transmitted, which may be composed of a plurality of frequency spectra. Preferably, the band resources at the edge of the bandwidth to be reduced are allocated to the resources to be added. This is because, in the existing wireless communication system, the frequency band received or transmitted by one transceiver is determined by the central frequency point and the bandwidth. If the intermediate frequency band resource in the bandwidth to be reduced is allocated to the bandwidth resource to be increased, Will take the original band to be reduced The wide resource is cut into two segments. In this case, two transceivers are required, and the resource resources in the bandwidth to be reduced near the edge are allocated to the resources to be added to avoid such a problem. It is to be noted that one of the bandwidths of the bandwidth resources to be reduced near the edge may be allocated to the resources to be added, or two spectrums may be allocated, which may be set according to actual needs. When the base station determines that the uplink resource required by the terminal service is greater than the required downlink resource, the part of the downlink frequency band resource originally used as the downlink resource is adjusted as the uplink resource, and the part of the downlink frequency band resource is called the secondary uplink resource, and the original uplink frequency band resource is used. As the main upstream band resource. As shown in FIG. 2A, a schematic diagram of using frequency band resources close to both side edges in the downlink frequency band resource as the uplink frequency band.

Similarly, when the base station determines that the downlink bandwidth resource required for the to-be-processed service is greater than the required uplink bandwidth resource, the downlink bandwidth resource is partially adjusted from the uplink bandwidth resource, and the part of the downlink frequency resource band is called the secondary downlink bandwidth. Resources, the original downlink bandwidth is the primary downlink bandwidth. As shown in FIG. 2B, a schematic diagram of adjusting the frequency band resources near the two side edges in the uplink frequency band as the downlink frequency band. The time slot resource is the performance of the physical layer actually occupying the frequency resource. First, the entire bandwidth is divided into different frequency bands, and users in the same frequency band are reallocated with different time slot resources, and the time slot resource occupied by each user is one channel. When the base station determines that the required uplink bandwidth resource is greater than the required downlink bandwidth resource, the part of the downlink time slot resource that is originally used as the downlink bandwidth resource is used as the uplink time slot resource, and the part of the downlink time slot resource is called the secondary uplink bandwidth resource. The original uplink bandwidth resource is used as the primary uplink bandwidth resource. As shown in FIG. 3A, a schematic diagram is used for using a part of downlink downlink resources in the downlink bandwidth as uplink time slot resources. Similarly, when the base station determines that the required downlink resource is greater than the required uplink bandwidth resource, the part of the uplink time slot resource that is originally used as the uplink bandwidth resource is used as the downlink time slot bandwidth resource, and the part of the uplink time slot resource is called the secondary downlink bandwidth resource. The original downlink bandwidth resource is called the primary downlink bandwidth resource. As shown in FIG. 3B, a schematic diagram of a part of an uplink time slot resource in an uplink bandwidth resource is used as a downlink time slot resource. Step 203: The resource configuration message is sent to the terminal, where the resource configuration message includes the information of the adjusted uplink resource and the downlink resource, so that the terminal adjusts the uplink resource and the downlink resource. The source carries the transmission of the service.

The manner in which the base station notifies the terminal resource configuration message may be sent by using a broadcast message. The resource configuration message may include: a bandwidth of the uplink or downlink main frequency band, a center frequency of the primary frequency band, and a corresponding uplink or downlink secondary frequency band. Bandwidth, the center frequency of the subband. For the case where the required uplink bandwidth resource is larger than the required downlink bandwidth resource, the base station sends a resource configuration message allocated to the terminal to the terminal on the PDCCH (physical downlink control channel) of the downlink frequency band. After receiving the resource configuration message, the terminal sends uplink control signaling to the base station only on the primary uplink bandwidth. The base station sends a resource configuration message through the downlink frequency band, where the uplink scheduling information includes: an RB (Resource Block) number, an RB position, an MCS (Modulation and Coding Scheme) order, and uplink frequency band information, and the terminal according to the The uplink scheduling information is used for data transmission in a specified frequency band, a specified RB position, and an MCS order. For the case where the required downlink bandwidth resource is larger than the required uplink bandwidth resource, the base station sends a resource configuration message to the terminal on the primary downlink bandwidth, and the base station sends uplink scheduling information only on the primary downlink bandwidth, and the uplink scheduling information includes: RB (Radio Resource Block) , Resource Block number, RB position, MCS (Radio Resource Block, Resource Block) order, and uplink band information. The base station schedules the data service, and the control signaling can be sent on the PDDCH of the primary downlink bandwidth or the PDDCH on the secondary downlink bandwidth.

According to the resource allocation method of the present embodiment, when the required uplink resource is greater than the downlink resource, the partial band resource is adjusted as the uplink resource from the downlink resource, or when the required downlink resource is greater than the uplink resource, the uplink bandwidth is used. The problem that the uplink resources or the downlink resources are wasted due to the imbalance between the uplink resources and the downlink resources in the existing wireless communication system is solved by adjusting the partial frequency band resources as the downlink resources. The third embodiment of the present invention provides a resource allocation apparatus, which is used to perform the resource allocation method of the first embodiment, and the applicable network architecture is the same as that of the foregoing embodiment, and details are not described herein again.

The sending module 303 is connected to the allocation module 302, and is configured to deliver the resource configuration to the terminal. The message, the resource configuration message includes the information of the adjusted uplink resource and the downlink resource, so that the terminal performs the service transmission according to the adjusted uplink resource and the downlink resource. The operation method and the embodiment of the resource allocation apparatus of the present embodiment are not described herein.

According to the resource allocation apparatus of the present embodiment, the uplink resource and the required downlink resource required by the terminal service are obtained by the statistic module 301. If the required uplink resource is larger than the downlink resource, some resources in the downlink resource are used.
