Embodiment 1

[0181] Such as image 3 As shown, the embodiment of the present invention provides a carrier aggregation capability reporting method, including:

[0182] S301. The user equipment UE determines carrier combination information supported by the UE, and sub-combination information of the carrier combination supported by the UE;

[0183] S302. The UE reports the determined carrier combination information supported by the UE and sub-combination information of the carrier combination supported by the UE to the base station.

[0184] In this embodiment, the supported carrier combination information determined by the UE may include the bandwidth level of carrier aggregation in each frequency band in the carrier combination, the MIMO capability corresponding to the bandwidth level of carrier aggregation in each frequency band, and the bandwidth level of carrier aggregation in each frequency band. Information such as the CSI capability corresponding to the bandwidth level. The bandwidt...

Embodiment 2

[0238] Such as Figure 6 As shown, the embodiment of the present invention provides a carrier aggregation capability reporting method, including:

[0239] S601. The user equipment UE determines capability information corresponding to each carrier in the carrier combination supported by the UE, where the capability information includes MIMO capability and / or CSI capability;

[0240] S602. The UE reports the determined capability information corresponding to each carrier to the base station.

[0241] In this embodiment, the capability information corresponding to each carrier may include MIMO capability and / or CSI capability, but is not limited thereto.

[0242] In this embodiment, the UE and the base station predefine sequence numbers, and each predefined sequence number represents a set of capability information corresponding to each carrier in the carrier combination supported by the UE. The UE reports the capability information corresponding to each carrier in the carrier ...

Embodiment 3

[0343] Such as Figure 9 As shown, the embodiment of the present invention provides a carrier measurement method, the method is executed by the UE, including:

[0344] S901. The user equipment UE reports to the base station indication information used to indicate that the UE supports parallel measurement of inter-frequency frequency points of carrier aggregation intra-carriers supported by the UE within a measurement interval;

[0345] S902. The UE receives the measurement configuration information including the inter-frequency frequency point of the carrier aggregation inner carrier supported by the UE and sent by the base station according to the indication information;

Abstract

The invention provides a communication device and method, so as to avoid the problem that UE repeatedly reports capability information corresponding to a carrier combination supported by the UE and reduce waste of reported signaling resources. The method comprises the following steps: receiving carrier range information from a base station, wherein the carrier range information comprises at leastone of a bandwidth upper limit of a carrier and a quantity upper limit of the carrier; and sending capability information to the base station according to at least one of the bandwidth upper limit ofthe carrier and the number upper limit of the carriers.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a carrier aggregation capability reporting device and method, and a carrier measurement device and method. Background technique [0002] Long Term Evolution (LTE for short) system needs to provide a maximum transmission bandwidth of 100MHz in order to meet the requirements of downlink transmission peak speed up to 1Gbps and uplink transmission peak speed up to 500Mbps. In order to solve the problem of continuous spectrum scarcity with large bandwidth, The LTE system proposes a carrier aggregation (English: Carrier Aggregation, CA for short) scheme. Carrier aggregation refers to the aggregation of two or more carrier units (English: Component Carrier, CC for short) to support a larger transmission bandwidth, and the maximum transmission bandwidth can reach 100 MHz. [0003] At present, in the carrier aggregation scheme, the user equipment (English: User Equipment, re...
