Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, embodiments of the present application will be described in detail hereinafter with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present application and features of the embodiments may be arbitrarily combined with each other.

The steps illustrated in the flowchart of the figures may be performed in a computer system, such as a set of computer-executable instructions. Also, while a logical order is depicted in the flowchart, in some cases, the steps depicted or described may be performed in a different order than presented herein.

The New air interface (NR) of the current fifth generation mobile communication technology (5th generation mobi4e networks,5G) uses a 4×4 multiple Input multiple Output (Mu 4tip4e-Input Mu4tip4 e-Output) antenna. The space multiplexing gain can be improved through the MIMO technology, and the uplink and downlink throughput capacity can be improved. MIMO systems typically have one antenna for four antennas, two antennas for five antennas, or two antennas for six antennas.

The number of multiplexing layers that can be supported by the terminal is limited by the number of receiving antennas. The NR frequency band of the 5G terminal uses 4-6 transceiving antennas to implement transmission of long term evolution (Long Term Evolution, LTE) and NR dual connectivity (E-UTRA-NR Dual Connectivity, ENDC), and is typically 4-6 antennas for Non-independent Networking (NSA) mode and typically 4 antennas for independent networking (SA) mode. The NR of the 5G terminal introduces a multi-antenna enhancement technology, and the spectrum efficiency, the cell coverage and the system flexibility are greatly improved.

The Sounding REFERENCE SIGNA (SRS) is an abbreviation of uplink Sounding reference signal, and is sent by the base station to the base station through a control signaling request terminal (UE). The SRS signal is a signal for detecting a channel state between the UE and the base station. And the base station evaluates the channel quality of the channel according to the strength and the interfered degree of the received SRS signals.

SRS belongs to a feedback technology between a base station and a terminal, and NR of a 5G terminal adopts a measurement and feedback mechanism of beam forming and is simultaneously applied to initial access, control and data channels. Beamforming (Beamforming) is one of multiple antenna techniques, and means that gNodeB/UE weights Uplink/downlink physical signals (Physical Downlink/Uplink SHARED CHANNEL, PDSCH/PUSCH) to form a narrow beam aimed at UE/gNodeB, and aims transmitting energy at a target terminal, so as to improve the demodulation signal-to-noise ratio of the target UE/gNodeB.

When the method is applied to initial access, an LTE period broadcast-based mechanism is improved to a beam forming-based mechanism, so that the coverage rate of a system is improved; and the coverage of a control channel is enhanced by adopting beam forming, so that the cell radius is enlarged, the transmission success rate can be improved, and the method is suitable for high-frequency transmission.

For the NR frequency bands of time division duplexing (Time Division Duplexing, TDD) and frequency division duplexing (Frequency Division Duplexing, FDD), SRS signals can be sent by switching between different carriers, or by switching between different antennas of the same carrier. The SRS technology utilizes channel reciprocity to further improve the channel feedback precision and the frequency spectrum efficiency of a communication system, and SRS signals are mainly responsible for uplink channel estimation between a terminal and a base station, modulation and coding strategy (Modulation and Coding Scheme, MCS) selection, uplink frequency selective scheduling, downlink beam forming selection and the like. The SRS is an uplink reference signal of NR of the 5G terminal, and may perform channel quality detection and estimation, beam management, and the like.

Fig. 1 is a schematic diagram of current 5G terminal antenna distribution, and fig. 1 illustrates two main current 5G frequency bands of 3.5GHz (N78) and 2.6GHz (N41). As shown in fig. 1, each of the NR1 and NR2 terminals has 4 antennas in the NR1 frequency band, and each of the NR1 frequency bands has 4 antennas, which are ANT1-NR1, ANT2-NR1, ANT3-NR1, ANT4-NR2; the NR2 band has 4 antennas, ANT1-NR2, ANT2-NR2, ANT3-NR2, ANT4-NR2, respectively. The 4G frequency band of the 4G radio frequency chip is provided with 4 antennae, which are ANT1-4G, ANT2-4G, ANT3-4G, ANT4-4G respectively. With different radio frequency front-end circuits in mind, one antenna transmission, two antennas receiving (1T 2R) and two for transmission, four for receiving (2T 4R) antennas may be implemented. The radio frequency front-end circuit includes various switches, frequency dividers, power dividers, etc. Part of the 5G terminals also use a mode of one antenna transmission and four antennas reception (1T 4R).

To efficiently use these 4 transmission paths per NR frequency band, it is necessary for the terminal to indicate the signal capability of each transmission path to the base station, i.e., to feed back channel information to the base station, so that the resources of the base station are more accurately allocated to each terminal. At present, the feedback channel information of the terminal has two different modes of PMI and SRS. The PMI is a preset mechanism by which the base station measures the measurement parameters by means of the terminal, then carries out various quantization algorithms, estimates channel information and resource requirements, and reports the channel information and the resource requirements to the base station. The SRS utilizes channel reciprocity to enable the terminal to directly report the channel information to the base station, and the channel information obtained by the SRS is more accurate. Meanwhile, in the SRS mode, the more antennas can participate in transmitting SRS signals, the more accurate the channel estimation is, and the higher the available download rate is.

FIG. 2a is a schematic diagram of a prior art 1T1R scheme; currently, the mainstream 5G terminals do not adopt SRS technology, but each antenna is fixedly transmitted, or adopt the PMI technology described above, which is equivalent to the 1T1R scheme in fig. 2a, as shown in fig. 2a, after the radio frequency chip (Radio Frequency Integrated Circuit, RF IC) passes through the front-end circuit TX1, signals are sent through 1 antenna, and signals are received through 1 antenna.

But the antennas receiving the feedback signals cannot be switched to PRX-MIMO and DRX-MIMO antenna channels.

Fig. 2c is a schematic structural diagram of a 2T4R scheme in the prior art, in which a part of 5G terminals may employ a 2T4R SRS scheme, as shown in fig. 2c, one transmitting antenna may be switched to a discontinuous reception (Discontinuous Reception, DRX) antenna, and another transmitting antenna may be switched to a DRX-MIMO antenna.

Fig. 2d is a schematic structural diagram of a 1T4R scheme in the prior art, a few 5G terminals adopt a 1T4R SRS technical scheme, and 4 antennas report channel information in turn, so that information acquired by a base station is more comprehensive, and more accurate data transmission is performed.

In the 1T1R scheme, a terminal is only fixed on one antenna and feeds back SRS information to a base station; the 1T2R scheme or the 2T4R scheme can alternately transmit SRS signals on 2 antennas, the 1T4R antenna can alternately transmit SRS signals on 4 antennas, the 1T4R and the base station are better matched, and the matched SRS mode can bring the value of 5G Massive MIMO into play to the maximum.

The SRS mode of the scheme is single, four SRS paths are relatively single and fixed, the mid-section is large in multi-stage switching loss, the switchable antenna range is relatively narrow, generally, the NR frequency band can only be switched to 4 antennas, and the switching to other antennas cannot be flexibly performed.
