Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a method, system, device and medium for sending a signal. Background Art

[0002] 5G's air interface technology (New Radio, NR) network supports "beamforming" technology, which can transmit in a directional manner to mobile terminals. If the base station wants to transmit in a directional manner, it needs to detect the location of the mobile terminal, the quality information of the transmission channel, etc., so that the base station's resources can be more accurately allocated to each mobile terminal. The mobile terminal sends the Sounding Reference Signal (SRS) information, which is one of the ways for the base station to detect the location and signal quality of the mobile terminal.

[0003] Among them, NR SRS in both standalone (SA) and non-standalone (NSA) networking has antenna rotation transmission. The more antennas participate in SRS transmission, the more accurate the signal estimation and precoding will be, and the higher the data transmission rate can be obtained. If it is only transmitted on a fixed antenna, the channel information of other antennas will be lost, the antenna will not be fully utilized, and it is difficult to obtain a higher rate.

[0022] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Unless otherwise defined, the technical terms or scientific terms used herein should be understood by people with general skills in the field to which the present invention belongs. "Including" and similar words used in this article mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0023] 5G air interface technology (New Radio, NR) mobile terminals are generally equipped with multiple transmit and receive antennas. Most frequency bands (BAND) use 2 transmit antennas and 4 receive antennas, that is, 2T4R. The mobile terminal transmits the sounding reference signal (SRS) on the 4 receive antennas in turn, and selects 2 antennas to transmit at a time. In addition, there are 1T1R, 1T2R and 1T4R.

[0024] In the NR standalone (SA) mode, all physical antennas are used in the NR mode. However, in the NR non-standalone (NSA) mode, in order to reduce costs, the physical antennas in the NR mode and the 4G air interface technology (LongTerm Evolution, LTE) mode need to be shared, resulting in a reduction in the number of physical antennas for sending SRS in the NR non-standalone mode, affecting the data transmission rate performance in the NR mode.

[0025] In view of the existing problems, an embodiment of the present invention provides a signal transmission method, which is applied to a terminal, wherein the terminal includes a management module, the terminal has an NR mode and an LTE mode, and the NR mode includes an NR independent networking mode and an NR non-independent networking mode. Figure 1 As shown, the method includes:

[0026] S101: The terminal saves the antenna configuration used when sending a sounding reference signal in the NR independent networking mode.

[0027] In this step, the terminal saves the antenna configuration used when sending the sounding reference signal in the NR independent networking mode, so as to quickly obtain the antenna configuration for signal transmission.

[0028] S102: When in the NR independent networking mode, obtain a first physical antenna corresponding to the antenna configuration.

[0029] In this step, if the terminal is in the NR independent networking mode, the first physical antenna corresponding to the antenna configuration can be directly obtained.

[0030] S103: Send a sounding reference signal according to the first physical antenna.

[0031] In this step, the terminal sends a detection signal according to the first physical antenna, thereby ensuring the performance of the data transmission rate.

[0032] S104: When in the NR non-independent networking mode, obtain a number of second physical antennas shared by the NR non-independent networking mode and the LTE mode.

[0033] In this step, when the terminal is in the NR non-independent networking mode, several second physical antennas shared by the NR non-independent networking mode and the LTE mode are obtained, and the first physical antenna corresponding to the antenna configuration is obtained.

It can be understood that in order to ensure the reliability of judging the physical antenna conflict based on the start time information and the duration information, the management module converts the start time information and the duration information into a unified clock information, such as the standard clock of the terminal.

[0036] When there is no antenna conflict, the second physical antenna is directly allocated and used according to the request information to complete the signal transmission. When there is an antenna conflict, the use of the second physical antenna is sorted according to the priority information to avoid the conflict of the use of the physical antenna, wherein the priority information includes the physical random access channel, physical uplink control channel, uplink shared physical channel, LTE detection reference channel and the detection reference channel in the NR non-independent networking mode in the LTE mode, and the priority order is the physical random access channel, the physical uplink control channel, the detection reference channel in the NR non-independent networking mode, the uplink shared physical channel and the LTE detection reference channel. When there is a conflict, sorting is performed according to the above priority order to maximize the data rate performance transmission of the mobile terminal.

[0037] S106: Send a sounding reference signal according to the second physical antenna allocated by the management module.

[0038] In this embodiment, since the antenna configuration used when sending the sounding reference signal in the NR independent networking mode is saved, the first physical antenna corresponding to the antenna configuration can be directly obtained to send the sounding reference signal. When in the NR non-independent networking mode, a number of second physical antennas shared by the NR non-independent networking mode and the LTE mode are obtained, and the request information is sent to the management module in advance. The request information includes priority information, physical antenna information, start time information and duration information.

The management module 304 allocates the shared second physical antenna according to the request information, thereby greatly improving the downlink rate performance of the NR mode, avoiding conflicts in the use of physical antennas, and maximizing the rate performance of the mobile terminal in the NR non-independent networking mode.

[0041] Optionally, the management module 304 determines in advance whether there is a conflict between the second physical antenna shared in the NR non-independent networking mode and the LTE mode based on the physical antenna information, the start time information and the duration information. When there is a conflict, the use of the second physical antenna is sorted and allocated according to the priority information. When there is no conflict, the second physical antenna can be directly allocated and used according to the request information, avoiding conflicts in the use of physical antennas and maximizing the rate performance of the mobile terminal in the NR non-independent networking mode.
