Embodiment Construction

[0015] In order to make the purpose, technical means and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings.

[0016] The basic idea of ​​the present application is to use the unoccupied idle subband resources of the PUCCH channel to transmit other information, thereby avoiding the waste of frequency resources.

[0017] Currently, for a multi-subband UE, resources occupied by its PUSCH channel include: resources of the last 5 OFDM symbols in the third subframe, and all resources in the fourth and fifth subframes. Wherein, on the third subframe, the PUSCH reference symbol is located on the seventh OFDM symbol; on the fourth and fifth subframes, the PUSCH reference symbol is located on the fifth OFDM symbol. In order to improve the transmission performance of the PUSCH channel more effectively, in this application, the idle subband resources not occupied by the PUCCH chann...

Abstract

The application discloses an uplink-channel distribution method for a communication system. The method includes: for multi-sub-band UE, using other sub-band resources excluding sub-band resources of a PUCCH channel of the UE on first four OFDM signs in a third subframe of wireless frames which are distributed for the UE, all resources on a fifth OFDM sign in the third subframe and all resources of a forth subframe and a fifth subframe as a PUSCH channel of the UE to be distributed to the UE. Through the above-mentioned method, sub-band resources which are not occupied by the PUCCH are distributed to the UE and used as the PUSCH channel so that wastage of frequency domain resources is prevented and transmission performance of the PUSCH is improved.

Description

technical field [0001] The present application relates to communication technologies, in particular to a method for allocating uplink channels of a communication system. Background technique [0002] The authorized frequency points of the power communication network are discretely distributed in the frequency band of 223.525MHz to 231.65MHz, a total of 40, each with a bandwidth of 25KHz, called physical sub-bands. The logical subbands correspond to the physical subbands 223.525 MHz to 231.65 MHz one by one. Each logical subband adopts OFDM as the basic technology to carry effective information. A user can support single subband or multi-subband transmission and reception, and the most capable UE can support 40 subband services. [0003] In the current power communication system, in the frequency domain, a subband includes effective subcarriers; in the time domain, a subframe contains 9 OFDM symbols. The PUCCH of a multi-subband UE only occupies the first 4 symbols of th...
