Problems solved by technology

However, when short TTIs such as 0.5ms TTI are used for PUSCH transmission, only one time slot in one TTI is used to transmit PUSCH, that is, there is only one DMRS in one TTI, the effect of channel estimation is poor, and frequency offset estimation cannot be realized

Abstract

Proposed are a communication method and a network device. The method comprises: a first network device sending a demodulation reference signal (DMRS) and a sounding reference signal (SRS) at a time unit, wherein a frequency domain resource of the SRS and a frequency domain resource of the DMRS are overlapped. According to the communication method and the network device provided in the embodiments of the present invention, a first network device sends both a DMRS and an SRS at a time unit, and a frequency domain resource of the DMRS and a frequency domain resource of the SRS are overlapped, so that a second network device can perform channel estimation on the time unit according to the DMRS and the SRS at the time unit and can realize frequency offset estimation at the time unit. The present invention can realize frequency offset estimation under the condition of a short TTI when being applied to a scenario with a short TTI.

Description

Technical field [0001] Embodiment of the invention relates to the field of communications, and more particularly, relates to a communication method and a network device. Background technique [0002] In the LTE (Long Term Evolution, LTE) system, the length of the subframe is 1ms. The length of the existing physical uplink shared channel (Physical Uplink Share Channel, PUSCH) and a physical downlink shared channel (PhysicalDownlink Share Channel, PDSCH) transmission scheduling time interval (Transmission Time Interval, TTI) is 1ms. To reduce system latency, low delay service to meet the requirements, the TTI length may be shortened at the physical layer, for example using the TTI length of 0.5ms carries user data, i.e. PUSCH and PDSCH scheduling TTI length is 0.5ms, thereby shortening round-trip delay (Round-Trip Time, RTT), to achieve a shorter physical layer data transfer delay. [0003] In the frame structure in the PUSCH 1ms TTI, 1ms TTI contains two 0.5ms slots, with each tim...
