Embodiment 1

[0045] This embodiment provides a resource allocation method, which is applicable to wireless communication systems with symmetrical bandwidth resources, such as CDMA, WCDMA or FDD LTE. First, the base station obtains the uplink resources and downlink resources required by the terminal service. If the required uplink resources are greater than the required downlink resources, the base station adjusts some resources from the downlink resources as uplink resources; or if the required downlink resources If the resources are greater than the required uplink resources, the base station adjusts some of the uplink resources as downlink resources, 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 service transmission according to the adjusted resource.

[0046] In this embodiment, a base station in FDD LTE is used ...

Embodiment 2

[0058] This embodiment provides a resource allocation method based on the first embodiment.

[0059] Step 201, acquire uplink resources and required downlink resources required by terminal services, the larger one of the required uplink resources and required downlink resources is the resource to be increased, and the smaller one is the resource to be reduced .

[0060] Optionally, the above-mentioned uplink resource may be an uplink bandwidth resource, and the downlink resource may be a downlink bandwidth resource.

[0061] The specific content of this step is the same as that of step 101, and will not be repeated here.

[0062] Step 202, adjust some resources from the resources to be reduced to the resources to be increased according to the ratio of uplink resources required by terminal services to required downlink resources.

[0063] Before the adjustment, the resources to be reduced and the resources to be increased are both S, when the ratio of the resources to be redu...

Embodiment 3

[0080] This embodiment provides a device for allocating resources, which is used to implement the method for allocating resources in Embodiment 1. The applicable network architecture is the same as that of the above-mentioned embodiments, and will not be repeated here. The device for allocating resources can be integrated in the base station.

[0081] Such as Figure 4 Shown is a schematic structural diagram of a resource allocation device according to this embodiment. The resource allocation device includes a statistics module 301 , an allocation module 302 and a delivery module 303 .

[0082] Among them, the statistical module 301 is used to obtain the required uplink resources and required downlink resources for terminal services, the larger one of the required uplink resources and the required downlink resources is the resource to be increased, and the smaller one is the resource to be decreased. Small resources; the allocation module 302 is connected to the statistics m...

Abstract

Provided are a resource allocation method and device, the method comprising: acquiring the uplink resource and downlink resource required for a terminal service, the larger one of the required uplink resource and downlink resource being a to-be-increased resource, and the smaller one being a to-be-decreased resource; allocating a part of the to-be-decreased resource to the to-be-increased resource; transmitting a resource allocation message to a terminal, the resource allocation message containing the information of the adjusted uplink resource and downlink resource, such that the terminal can transmit a service according to the adjusted uplink resource and downlink resource. The resource allocation method and device in an embodiment of the present invention can adjust the bandwidth resource required for a terminal, thus solving the problem of resource waste caused by the imbalance between an uplink resource and a downlink resource required in a wireless communication system.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a resource allocation method and device. Background technique [0002] Existing wireless bandwidth communication systems, such as CDMA (Code Division Multiple Access, Code Division Multiple Access), WCDMA (Wideband Code Division Multiple Access, Wideband Code Division Multiple Access) and FDD LTE (Frequency Division Duplexing Long Term Evolution, Frequency Division Dual long-term evolution), etc., the uplink and downlink resources are symmetrical and equal, and the resources here mainly refer to bandwidth. [0003] With the popularization and application of the wireless mobile communication system, more and more asymmetric services will be transmitted through the wireless mobile communication system, such as: mobile TV, network downloading and so on. In these special networks, more downlink resources are used, while less uplink resources are used. If such a resource-s...
