Problems solved by technology

In this way, when the number of resource blocks occupied by PUSCH is small, the number of subcarriers occupied by PUSCH is also small, which will lead to a narrow bandwidth of PUSCH in the frequency domain, and cannot fully obtain the frequency domain selectivity of the channel. diversity gain

Abstract

The invention discloses a communication method and device. The method comprises the following steps: the terminal equipment receives the first message from the network equipment, and the terminal equipment sends an uplink data signal to the network equipment on the N subcarriers indicated in the first message, wherein the N subcarriers are distributed in M resource blocks RB, the number of subcarriers used for sending uplink data signals in each RB in the M RBs is L, M is larger than or equal to 2, L is smaller than K, K is the number of subcarriers included in one RB, and N, M, L and K are all positive integers. By adopting the technical scheme, the PUSCH can occupy a part of subcarriers in one RB to send the uplink data signal, so that the frequency domain range of a channel experiencedby the PUSCH can be widened, diversity gain brought by frequency domain selectivity of the channel is fully obtained, and the transmission performance of the PUSCH is improved.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a communication method and device. Background technique [0002] In the prior art, an uplink data signal sent by a terminal device to a network device is carried on a physical uplink shared channel (PUSCH), and the PUSCH occupies an integer number of physical resource blocks (physica resource blocks, PRB) in the frequency domain. , and mapped on all subcarriers included in the PRB. In this way, when the number of resource blocks occupied by PUSCH is small, the number of subcarriers occupied by PUSCH is also small, which will lead to a narrow bandwidth of PUSCH in the frequency domain, and cannot fully obtain the frequency domain selectivity of the channel. Diversity gain. Contents of the invention [0003] Embodiments of the present application provide a communication method and device, which improve transmission performance of uplink data signals by utili...
