Problems solved by technology

However, the significant disadvantage of the above capacity enhancement technology is that in the current LTE, when SRS is sent on the time-frequency resource of PUSCH, the frequency resource will no longer be used to send PUSCH, so the uplink throughput of data will be affected.

Embodiment Construction

[0060] Embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.

[0061] In the existing LTE system, the base station measures the channel quality of the uplink based on the Sounding Reference Signal (SRS) sent by the UE. Since the SRS needs to reflect the channel quality of various frequency bands to the base station, in the frequency domain, the SRS transmission should Cover the frequency band that the base station tuner is interested in. Generally, frequency band coverage can be achieved in the following ways:

[0062] The first way is to cover the entire frequency band of interest by sending a sufficiently large wideband SRS (wideband SRS). When wideband SRS is used for uplink transmission, the entire frequency band of interest can be reported to the base station by using only one SRS transmission in one symbol, so from the perspective of resource utilization, the entire frequency band can be d...

Abstract

Embodiments of the invention disclose a data transmitting method, a related device and a related system. The method comprises: a network device transmits resource location information of a first reference signal and a physical channel to a terminal; a first time-frequency resource mapped by and corresponding to the first reference signal is overlapped with a second time-frequency resource corresponding to the physical channel, wherein the overlapped resource is not used for physical channel transmission, and a third time-frequency resource of the second time-frequency resource except for the overlapped resource is used for physical channel transmission, or the overlapped resource is used for transmitting a second reference signal, or an overlapped region is used for transmitting the secondreference signal, the terminal does not transmit the first reference signal, and the second reference signal is orthogonal to the first reference signal; and the network device receives the physicalchannel and the second reference signal transmitted by the terminal. By using the embodiments of the invention, multiplexing PUSCH and SRS in the time-frequency resources for uplink transmission may be implemented, and the influence of SRS capacity expansion to data uplink throughput may be reduced.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a data sending method, related equipment and a system. Background technique [0002] The uplink physical channel in the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) Long Term Evolution (Long Term Evolution, LTE) system includes a Physical Random Access Channel (Physical Random Access Channel, PRACH for short), a Physical Uplink Shared Channel (Physical uplink shared channel, PUSCH), physical uplink control channel (Physical uplink control channel, PUCCH). There are also two physical uplink reference signals, one is the demodulation reference signal (Demodulation Reference Signal, DMRS) used to demodulate the data / control signaling, and the other is the sounding reference signal used to measure the uplink channel (Sounding Reference Signal, SRS). [0003] Among them, the base station detects the uplink channels of different frequenc...
