Signaling indication of reference signal, method and device for transmitting reference signal

Cross-reference to related applications

The present application is based on a Chinese patent application filed on Jan. 16, 2017, the entire disclosure of which is hereby incorporated by reference.

Technical field

The present invention relates to the field of communications, and in particular, to a signaling indication of a reference signal, a method and a device for transmitting a reference signal.

Background technique

In the related art, in the LTE (Long Term Evolution), 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 is divided into DCI format 0, 1, 1A, 1B, 1C, 1D, 2, 2A, 3, 3A, etc., and later evolved to LTE-A Release 12 (LTE- DC version 2B, 2C, and 2D have been added to A version 12) to support a variety of different applications and transmission modes. The evolved base station (eNB, e-Node-B) may configure the user equipment (UE, User Equipment) through the downlink control information, or the second communication node device may receive the configuration of the higher layers, which is also configured by using high layer signaling. UE.

The Sounding Reference Signal (SRS) is a signal used by the UE and the eNB to measure Channel State Information (CSI). In the LTE system, the UE periodically transmits an uplink SRS on the last data symbol of the transmission subframe according to parameters such as a frequency band, a frequency domain position, a sequence cyclic shift, a period, and a subframe offset indicated by the eNB. The eNB determines 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 LTE-A Release 10 (LTE-A Release 10) study, it is proposed that in uplink communication, non-precoded SRS should be used, that is, antenna-specific SRS, and physical uplink shared channel (PUSCH, Physical Uplink). The reference signal (DMRS, De Modulation Reference Signal) for demodulation of the Shared Channel is precoded. The eNB can estimate the original CSI of the uplink by receiving the non-precoded SRS, and the pre-coded DMRS cannot enable the eNB to estimate the original CSI of the uplink. At this time, when the UE transmits the non-precoded SRS by using multiple antennas, the SRS resources required by each UE are increased, which results in a decrease in the number of UEs that can be simultaneously multiplexed in the system. The UE may send the SRS by using the high-level signaling (also referred to as triggered by the trigger type 0) or the downlink control information (also referred to as triggering by the trigger type 1), and the periodic SRS is triggered based on the high-level signaling, and is based on the downlink. The control information triggers a non-periodic SRS. In the LTE-A Release 10, the manner of aperiodic transmission of SRS is added, which improves the utilization of SRS resources to some extent and improves the flexibility of resource scheduling.

With the development of communication technology, the demand for data services continues to increase, and the available low-frequency carriers are already very scarce. Therefore, high-frequency (30-300 GHz) carrier communication based on underutilization has become an important communication for solving high-speed data communication in the future. One of the means. The high bandwidth available for high frequency carrier communication provides efficient high speed data communication. However, a big technical challenge faced by high-frequency carrier communication is that relatively low-frequency signals, the fading of high-frequency signals in space is very large, although the high-frequency signals in the outdoor communication have a spatial fading loss problem, but because of With its wavelength reduction, more antennas can usually be used so that communication can be based on the beam to compensate for fading losses in space.

However, when the number of antennas increases, since each antenna needs to have a set of RF links at this time, digital beamforming also brings about an increase in cost and power loss. Therefore, research in the related art tends to mix beamforming, that is, the radio frequency beam and the digital beam together form a final beam.

In the research of the new radio access technology (New Radio Access Technology), in addition to the eNB, a large number of antennas are configured to form a downlink transmission beam to compensate for the spatial fading of high-frequency communication, and the UE also configures a large number of antennas. The uplink transmission beam, at this time, the transmission of the SRS will also be transmitted in the form of a beam. In the future SRS research, in order to improve the flexibility of SRS resource scheduling, enhance the orthogonality of SRS between users, and at the same time take into account the SRS transmission sequence peak-to-average ratio (PAPR), how to generate SRS sequences is a solution to be solved. problem.

There is currently no effective solution to the problem of how to generate and transmit measurement reference signals in a new system in the related art.
