Abstract

A resource distribution method for a physical uplink shared channel is characterized by comprising the steps of enabling the physical uplink shared channel (PUSCH) of multi-subband user equipment (UE) to occupy symbols 4-8 of a subframe 2, a subframe 3 and a subframe 4; configuring PUSCH demodulation reference signals in the subframes by combining phase factors, and transmitting the PUSCH demodulation reference signals and data through the subframes. The invention further discloses a resource distribution device for the physical uplink shared channel. A high PAPR (peak to average power ratio) is avoided, and accordingly performance of a whole system is improved.

Description

technical field

[0001] The present invention relates to the technical field of communication, and more specifically, to a resource allocation method and device for a physical uplink shared channel. Background technique

[0002] With the continuous improvement of the terminal's demand for speed, the wireless communication system (power grid) of the State Grid has introduced multi-subband services. Based on the uplink multi-subband service, the terminal can realize high-speed services such as real-time video collection and large data volume data collection. The State Grid wireless communication system adopts Orthogonal Frequency Division (OFDM) as the basic technology, and each channel carries a subband of effective information. A user (UE) can support single subband or multi-subband transmission and reception, and the most capable UE can support 40 subband services.

[0003] In this system, the length of the demodulation reference sequence of the Physical Uplink Shared Chan...
