Method, system and device for realizing the distribution of sources

Abstract

The present invention provides a method for realizing the distribution of sources, which comprises the following steps: ability grades for supporting SF are arranged at a terminal, and ability information containing the SF ability grades is reported to a network side; after the network side knows the ability information of the terminal containing the ability grades for supporting the SF, a base station is noticed; sources are distributed to the terminal by the base station according to the ability information; the terminal receives and obtains down data in a united detecting type on the source of the base station distributed to the terminal. The present invention also provides a system and a device for realizing the distribution of the sources. By using the method, the system and the device, the complexity of the united detection processing of an MIMO terminal can be simplified; and meanwhile, the terminal can be arranged to support different SFs, so the complexity of hardware realization and development of terminal firm developing products can also be simplified.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method, system and device for realizing resource allocation. Background technique [0002] With the development of mobile communication technology, MIMO (Multiple Input Multiple Output) technology is gradually introduced in HSPA+ (High Speed ​​Packet Access Plus, High Speed ​​Packet Access Evolution), so that the downlink can use multiple antennas The array sends two independent data streams in parallel, further improving the system's data transfer rate and transfer quality. In the TDD (Time Division Duplex, Time Division Duplex) HSPA+ system, the downlink channel HS-DSCH (High SpeedDownlink Shared Channel, high-speed downlink shared channel) can use SF (SpreadingFactor, spreading factor) with a value of 1 or 16 Physical channel for transmission: when SF=1, each time slot provides one code channel, which is equivalent to no spread spectrum; when SF=16, eac...

AI Technical Summary

Problems solved by technology

[0003] However, in the existing TDD system, terminals requiring MIMO (referred to as MIMO terminals) support a maximum spreading factor level of SF=16, that is, the number of code channels must be supported to be 16, and a maximum of 16 code channels of SF=16 can be supported in parallel. Therefore, after receiving the capability information reported by the terminal accessing the network on the network side and allocating resources to it according to the capability information of the terminal, the SF value supported by the MIMO terminal can always be 16. Therefore, the resources allocated for it are often allocated not according to the SF capability level it supports but according to the scheduling situation, that is, it does not need to be configured with full code channels, and at the same time, because the joint detection and reception complexity of MIMO terminals in TDD will increase with the code channel Therefore, when the existing system requires that the maximum SF supported by the MIMO terminal is 16, when it receives and decodes multiple parallel data streams in the downlink, The complexity of joint detection and reception will be greatly increased; in addition, when terminal manufacturers develop terminal products according to the setting of the maximum supportable SF=16, it will inevitably increase the complexity of terminal hardware implementation and development
