Embodiment 1

[0230] figure 1 It is a schematic flowchart of a bandwidth configuration method provided in Embodiment 1 of the present invention. The method is implemented by a bandwidth configuration device configured in the UE, such as figure 1 As shown, the methods include:

[0231] Step 101, UE receives at least one piece of virtual bandwidth configuration information.

[0232] Specifically, the UE receives at least one piece of virtual bandwidth configuration information sent by the base station, wherein, optionally, the at least one may also be at least two, the virtual bandwidth configuration information is used to indicate the configuration of the virtual bandwidth, and the virtual bandwidth There is a one-to-one relationship between configuration information and virtual bandwidth, that is, one piece of virtual bandwidth configuration information indicates the configuration of one virtual bandwidth. The receiving of the virtual bandwidth configuration information by the UE may spe...

Embodiment 2

[0242] In the above embodiment, in step 101, the UE receives at least one piece of virtual bandwidth configuration information, where the number of virtual bandwidth configuration information is at least two. When the UE receives at least two pieces of virtual bandwidth configuration information, such as figure 2 As shown, the method may include:

[0243] Step 201, the UE receives at least two pieces of virtual bandwidth configuration information.

[0244] Step 202, the UE receives first configuration information.

[0245] Specifically, the first configuration information is used to instruct the UE to perform signal reception or signal processing according to a virtual bandwidth corresponding to at least one virtual bandwidth configuration information in the at least two virtual bandwidth configuration information.

[0246] Wherein, step 202 is optional, and step 203 may be directly performed.

[0247] Step 203, the UE performs signal reception and / or signal processing acc...

Embodiment 3

[0251] Embodiment 3 of the present invention is optimized on the basis of the above-mentioned embodiments, such as image 3 As shown, the method may also include:

[0252] Step 301. The UE receives second configuration information for performing signal reception and / or signal processing on the virtual bandwidth.

[0253] Specifically, the second configuration information is configuration information of the signal or signal processing, which may be configured independently of the virtual bandwidth configuration information, or may be predefined, and sent to the UE through the base station. In addition, the second configuration information may be parameter configuration information such as scrambling information of the signal, port information, time domain parameters, frequency domain parameters, etc., and may also be configurations of signal processing such as channel estimation, signal detection, and data demodulation. information, without limitation.

[0254] Optionally, in...

Abstract

The embodiment of the invention provides a bandwidth allocation method and device, user equipment and a base station. The method comprises: a user equipment receiving at least one piece of virtual bandwidth configuration information, the virtual bandwidth configuration information being used for indicating configuration of a virtual bandwidth; and the user equipment performs signal receiving and / or signal processing according to at least one virtual bandwidth in the virtual bandwidths indicated by the at least one piece of virtual bandwidth configuration information, wherein each virtual bandwidth is a part or all of a downlink maximum available bandwidth or a downlink transmission bandwidth, and the downlink maximum available bandwidth is a maximum bandwidth which can be used for downlinktransmission. According to the embodiment of the invention, the overhead and the complexity of signal receiving and signal processing are reduced, and the overhead and the complexity of signal receiving and processing feedback can be flexibly controlled.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a bandwidth allocation method, device, user equipment and base station. Background technique [0002] In a Long Term Evolution (LTE for short) system, each cell has a fixed downlink transmission bandwidth. A user equipment (User Equipment, hereinafter referred to as UE) obtains a downlink transmission bandwidth by receiving broadcast information, and then receives signals and / or performs signal processing based on the downlink transmission bandwidth. [0003] At present, in the LTE system, for the UE, measurement and feedback are performed based on a bandwidth, such as the downlink transmission bandwidth, which leads to problems of inflexible and high complexity in overhead and signal reception and / or processing. Contents of the invention [0004] Embodiments of the present invention provide a bandwidth allocation method, device, user equipment, and base ...
