Description

Configuration for sending uplink signals, and method, device and system for sending uplink signals

Technical Field

The present invention relates to the field of communications, and in particular, to an uplink signal transmission configuration, an uplink signal transmission method, an apparatus, and a system.

Background

In the related art, in Long Term Evolution (LTE), a Physical Downlink Control Channel (PDCCH) is used to carry uplink and Downlink scheduling information and uplink power Control information. Downlink Control Information (DCI) format (format) is divided into DCI formats 0, 1A, 1B, 1C, 1D, 2A, 3A, etc., and then, DCI formats 2B, 2C, 2D are added to LTE-a Release12(LTE-a Release 12) to support various applications and transmission modes. The first communication Node (e-Node-B, abbreviated as eNB) may configure a second communication Node device (UE) through downlink control information, or the second communication Node device receives configuration of a higher layer (high layer), which is also called to configure the UE through higher layer signaling.

A Sounding Reference Signal (SRS) is a Signal used between the second communication node device and the first communication node device to measure wireless Channel Information (CSI). In a long term evolution system, a UE (user equipment) transmits an uplink SRS (sounding reference signal) on the last data symbol of a transmission subframe at fixed time according to parameters such as a frequency band, a frequency domain position, a sequence cyclic shift, a period and subframe offset indicated by an eNB (evolved node B). And the eNB judges the uplink CSI of the UE according to the received SRS, and performs operations such as frequency domain selection scheduling, closed-loop power control and the like according to the obtained CSI.

In the research of a New Radio Access Technology (New Radio Access Technology), in addition to a first communication node of a high-frequency communication system configuring a large number of antennas to form downlink transmission beams to compensate for spatial fading of high-frequency communication, a second communication node of a user also configures a large number of antennas to form uplink transmission beams, and at this time, SRS transmission is also transmitted in the form of beams. The physical uplink control channel PUCCH includes a long format PUCCH and a short format PUCCH, and the short format PUCCH may occupy the last 1 or more symbols of the slot. When the SRS is also located in the last 1 or more symbols of the slot, how to perform multiplexing transmission of uplink signals or preferentially transmit a certain uplink signal is a problem to be solved.

For the problem of how to transmit uplink signals in the related art, no effective solution exists at present.
