Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of communications, and in particular, to a method, apparatus, system, storage medium and electronic device for transmitting SRS. BACKGROUND

[0002] In Long Term Evolution (LTE), Physical Downlink Control Channel (PDCCH) is used to carry Downlink Control Information (DCI), which can include uplink and downlink scheduling information, and uplink power control information. DCI formats include DCI format 0, 1, 1A, 1B, 1C, 1D, 2, 2A, 3, 3A, and the like. In LTE-A Release 12, DCI formats 2B, 2C, and 2D are added to support a variety of different applications and transmission modes. A first communication node, such as an e-Node-B (eNB), can configure a second communication node device, such as a User Equipment (UE), through downlink control information, or the second communication node device accepts configuration of higher layers, also known as configuration through higher layer signaling. The first communication node can be a base station of a macro cell, a base station of a small cell, a transmission node of a high frequency communication system, a transmission node of an Internet of Things system, a satellite node, and the like. The second communication node can be a UE, a mobile phone, a portable device, a vehicle, a satellite node, and the like.

[0003] A Sounding Reference Signal (SRS) is a signal used by a second communication node device to measure Channel State Information (CSI) with a first communication node. In a Long Term Evolution system, a UE transmits an uplink SRS on the last data symbol of a transmission subframe according to the frequency band, frequency domain position, sequence cyclic shift, period, and subframe offset indicated by an eNB. The eNB determines the uplink CSI of the UE according to the received SRS, and performs frequency domain selection scheduling, closed loop power control, and the like according to the obtained CSI.

[0004] Research in LTE-A Release 10 proposed using a non-precoded SRS (i.e., antenna-specific SRS) for uplink communications, while precoding the demodulation reference signal (DMRS) for the Physical Uplink Shared Channel (PUSCH). A first communication node can estimate the original uplink CSI by receiving the non-precoded SRS, whereas precoded DMRS prevents this from happening. Therefore, when a UE uses multiple antennas to transmit a non-precoded SRS, the SRS resources required for each UE increase, reducing the number of UEs that can be simultaneously multiplexed within the system. UEs can transmit SRS using either high-layer signaling (also known as trigger type 0) or downlink control information (also known as trigger type 1). SRS triggered by high-layer signaling is called periodic SRS, while SRS triggered by downlink control information is called aperiodic SRS. LTE-A Release 10 adds a non-periodic SRS transmission method, which improves the utilization of SRS resources to a certain extent and enhances the flexibility of resource scheduling.

[0005] In the Rel-15 NR (New Radio Access) research, the uses of SRS are divided into four categories: beam management, codebook-based, non-codebook-based, and antenna switching.

[0006] In the research of Rel-17 NR (New Radio Access), how to further enhance the coverage and reuse capacity of SRS and reduce interference to adjacent cells is an issue to be solved.

[0007] It can be seen from this that the related art has the problem that the coverage range and multiplexing capacity of SRS are small, and interference is caused to adjacent cells.

[0008] Currently, no effective solution has been proposed to the above-mentioned problems existing in the related technologies. Summary of the Invention

[0033] In the embodiment, a method for transmitting SRS is provided, Figure 1 The method for transmitting SRS according to the embodiment of the present disclosure Figure 2 As shown in Figure 3 The method includes the following steps:

[0034] In step S202, configuration information sent by a first communication node via signaling is received, and a sounding reference signal (SRS) is sent to the first communication node based on the configuration information. Alternatively, the SRS is sent to the first communication node according to a rule agreed with the first communication node.

[0035] In the above embodiment, the SRS sent can be a partial frequency hopping SRS transmission. The partial frequency hopping SRS can accelerate the speed of obtaining channel information by the base station, and can also be staggered with the services of other users in the frequency domain to reduce interference to other users.

[0037] Through the present disclosure, by sending the sounding reference information SRS based on the configuration information sent through signaling, or by sending the SRS based on the agreed rules, the coverage and multiplexing capacity of the SRS can be enhanced. Therefore, the problems existing in the related art of small coverage and multiplexing capacity of the SRS and interference to adjacent cells can be solved, thereby achieving the effect of enhancing the coverage and multiplexing capacity of the SRS and reducing interference to adjacent cells.

[0038] In an exemplary embodiment, the signaling includes at least one of the following: information indicating the number of times a periodic SRS or a semi-persistent SRS is repeatedly transmitted in the time domain or between time slots; information indicating the number of times an SRS resource set is repeatedly transmitted in the time domain or between time slots; information indicating that a non-periodic SRS does not detect the full hop bandwidth; information indicating that an SRS is transmitted at the same frequency domain position as the frequency domain position of a previous time domain transmission unit; information indicating that an SRS is transmitted at the same frequency domain position as the frequency domain position of a next time domain transmission unit; information indicating that the transmission comb of the SRS is jumped or randomized between SRS resources. In this embodiment, when the transmitted sounding reference signal SRS is a partially frequency hopping SRS, and the signaling indicates that the number of times a periodic SRS or a semi-persistent SRS is repeatedly transmitted in the time domain or between time slots is 2, a schematic diagram of reusing each subband in a plurality of subbands to transmit the SRS can be found in the attached. Figure 3 ,like Figure 3 As shown, Figure 3 The area a in the middle is used to show the frequency hopping from sub-band 1 to sub-band 4 in the frequency domain, which is enhanced to Figure 4 The b area in the middle shows that the signal is repeated twice in sub-band 1 and twice in sub-band 3. SRS The number of SRS transmissions is counted up in the order of 0, 0, 1, 1, ...

[0039] In an example embodiment, the rule agreed with the first communication node comprises at least one of the following: when the SRS is periodic SRS or semi-persistent SRS, the number of times of repeating sending in time domain or between slots is the ratio of the hopping bandwidth and the multiple sending bandwidth, wherein the multiple sending bandwidth is the product of the sending bandwidth and the number of different sending positions in frequency domain; when the frequency domain position of the SRS is located at a frequency domain position where SRS cannot be sent, or when the frequency domain position of the SRS completely or partially overlaps with the frequency domain of other signals, the SRS frequency domain position at the current time domain position is updated to the frequency domain position corresponding to the time domain position of the last time SRS is sent; when the frequency domain position of the SRS is located at a frequency domain position where SRS cannot be sent, or when the frequency domain position of the SRS completely or partially overlaps with the frequency domain of other signals, the SRS frequency domain position at the current time domain position is updated to the frequency domain position corresponding to the time domain position of the next time SRS is sent; when the frequency domain position of the SRS is located at a frequency domain position where SRS cannot be sent, or when the frequency domain position of the SRS completely or partially overlaps with the frequency domain of other signals, the number of transmissions of the SRS is not accumulated; when the frequency domain position of the SRS is located at a frequency domain position where SRS cannot be sent, or when the frequency domain position of the SRS completely or partially overlaps with the frequency domain of other signals, the number of transmissions of the SRS is N, wherein N is an integer greater than or equal to 2 and less than or equal to 10; R is a repetition factor configured by the first communication node through a high layer parameter, R partial is a factor configured by the first communication node through a high layer parameter for indicating repetition between SRS resources or SRS resource sets; in the case of periodic SRS or semi-persistent SRS, the calculation manner of the number of SRS transmissions is:

[0040]

[0041] wherein l' is the orthogonal frequency division multiplexing, OFDM, symbol number within the SRS resource, R is a repetition factor configured by the first communication node through a high layer parameter, R partial is a factor configured by the first communication node through a high layer parameter for indicating repetition between SRS resources or SRS resource sets or between SRS sending slots, is the number of continuous OFDM symbols occupied by the SRS resource, is the number of slots per frame when the subcarrier spacing is μ, n f is the system frame number, is the slot number within the frame when the subcarrier spacing is μ, T SRS is the slot period of the SRS, T offset is the slot offset of the SRS; the sending comb offset of the SRS is obtained based on at least one of the following parameters: symbol or slot index, index of frequency domain subband or frequency band, cell identification, ID, or UE identification, ID, number of transmissions of the SRS nSRS In this embodiment, when the frequency domain position of the SRS is located at a frequency domain position where the SRS cannot be sent, for example, when the current time domain position is occupied, the frequency domain position of the SRS at the current time domain position can be updated to the frequency domain position corresponding to the time domain position of the last time SRS transmission, or the frequency domain position of the SRS at the current time domain position can be updated to the frequency domain position corresponding to the time domain position of the next time SRS transmission, thereby avoiding interference with adjacent cells. The schematic diagram of updating the frequency domain position of the SRS at the current time domain position to the frequency domain position corresponding to the time domain position of the last time SRS transmission can be found in the attached figure. Figure 4 ,like Figure 4 As shown, Figure 4 The a region in FIG is used to show that a conventional UE sends SRS on subbands 1-4. Figure 5 The b area in the figure is used to illustrate that the UE in the embodiment of the present disclosure does not transmit SRS in subband 3, but repeatedly transmits SRS in subband 1. In this case, the number of SRS transmissions is counted cumulatively in the order of 0, 0, 2, 3, ... . The schematic diagram of updating the SRS frequency domain position at the current time domain position to the frequency domain position corresponding to the next time domain position for transmitting SRS can be found in the attached figure. Figure 5 ,like Figure 5 As shown, Figure 5 The a region in FIG is used to show that a conventional UE sends SRS on subbands 1-4. Figure 6 Area b in the figure is used to show that the UE in the embodiment of the present disclosure does not send SRS in subband 3, but repeatedly sends SRS in subband 2. In this case, the number of SRS transmissions is accumulated and counted in the order of 0, 2, 2, 3, ...

[0042] In this embodiment, when the SRS is aperiodic SRS, partial frequency hopping in the aperiodic SRS resource (aperiodic SRS configuration) can be introduced to enhance the coverage of the SRS. Assuming that all symbols in the slot can be used for SRS transmission, each SRS resource (SRS configuration) is supported to contain 8 symbols and a repetition factor of R = 2. If R = 4 is configured, then according to the existing standard protocol, the frequency domain needs to be occupied. In this case, the hopping bandwidth configured by RRC needs to be completed by hopping in the resource, which can only be achieved as follows: Figure 7 The frequency hopping pattern shown in area b in FIG. 1 shows that after introducing partial frequency hopping in the aperiodic SRS resource, only part of the subband needs to be sent to transmit SRS, which can be achieved as follows: Figure 7 Compare the frequency hopping pattern shown in area b inFigure 6 The frequency domain bandwidth of the b region in Figure 7 The b region in Figure 7 The frequency domain bandwidth of the b region in Figure 8 The frequency domain bandwidth of the b region in is half, when the transmission power is the same, the smaller the frequency domain bandwidth is, the greater the transmission energy will be, and the coverage will also be greater.

[0043] In an embodiment, the transmission comb offset of the SRS can be based on the transmission number n of the SRS SRS obtained, comprising: the transmission comb offset of the SRS transmitted on the p i antenna port is:

[0044]

[0045] wherein, is the SRS transmission comb offset configured by the first communication node through the high layer parameter, n SRS is the transmission number of the SRS, K TC is the number of transmission combs, is the cyclic shift of the SRS sequence, is the maximum number of cyclic shifts of the SRS sequence, is the number of antenna ports of the SRS. In this embodiment, for Rel-17 SRS enhancement, as the number of SRS transmission combs increases, the transmission power of the SRS will also further increase, and if there is no cooperation of SRS related information between cells, it will bring a lot of inter-cell interference. Therefore, it can be considered that the comb offset of the SRS changes with the frequency hopping within the aperiodic SRS resource, so as to achieve the purpose of interference randomization. That is, when the comb offset changes, the carrier used to transmit the SRS will also change accordingly, so the transmission comb offset associated with the transmission mode can be determined first, the carrier used to transmit the SRS is determined based on the comb offset, and the SRS is transmitted on the carrier. Wherein, the comb offset can be associated with symbol / slot index or frequency domain sub-band or frequency band index, cell ID or UE ID for randomization.

[0046] In this embodiment, a transmission method of SRS is provided, Figure 2 is a flow of the transmission method of SRS according to the embodiments of the present disclosure Figure 8 as shown in Figure 3 , the flow includes the following steps:

[0047] Step S802: Send configuration information to the second communication node through signaling, and receive the sounding reference signal SRS sent by the second communication node based on the configuration information; or, receive the SRS sent by the second communication node according to the rules agreed with the second communication node.

[0048] In the above embodiment, the transmitted sounding reference signal (SRS) may be a partially frequency-hopped SRS. This partially frequency-hopped SRS can accelerate the base station's acquisition of channel information and can also stagger services of other users in the frequency domain, thereby reducing interference to other users. Furthermore, repeated partial frequency hopping can be used to enhance SRS coverage.

[0049] The execution subject of the above steps may be a first communication node, wherein the first communication node may be a base station of a macro cell, a base station or transmission node of a small cell, a sending node in a high-frequency communication system, a sending node in an Internet of Things system, a satellite node, etc. The above-mentioned second communication node may be a UE, including but not limited to a mobile phone, a portable device, etc., and may also be a node in a communication system such as a vehicle-mounted terminal or a satellite node.

[0050] Through the present disclosure, by sending the sounding reference information SRS based on the configuration information sent through signaling, or by sending the SRS based on the agreed rules, the coverage and multiplexing capacity of the SRS can be enhanced. Therefore, the problems existing in the related art of small coverage and multiplexing capacity of the SRS and interference to adjacent cells can be solved, thereby achieving the effect of enhancing the coverage and multiplexing capacity of the SRS and reducing interference to adjacent cells.

[0051] In one embodiment, the signaling includes at least one of the following: information indicating the number of times a periodic SRS or a semi-persistent SRS is repeatedly transmitted in the time domain or between time slots; information indicating the number of times an SRS resource set is repeatedly transmitted in the time domain or between time slots; information indicating that a non-periodic SRS does not detect the full hop bandwidth; information indicating that an SRS is transmitted at the same frequency domain position as the frequency domain position of a previous time domain transmission unit; information indicating that an SRS is transmitted at the same frequency domain position as the frequency domain position of a next time domain transmission unit; information indicating that the transmission comb of the SRS is jumped or randomized between SRS resources. In this embodiment, when the transmitted sounding reference signal SRS is a partially frequency hopping SRS, and the signaling indicates that the number of times a periodic SRS or a semi-persistent SRS is repeatedly transmitted in the time domain or between time slots is 2, a schematic diagram of reusing each sub-band in a plurality of sub-bands to transmit the SRS can be found in the attached figure. Figure 3 ,like Figure 3 As shown, Figure 3 The area a in the middle is used to show the frequency hopping from sub-band 1 to sub-band 4 in the frequency domain, which is enhanced to Figure 4The middle b region shows that the sub-band 1 is repeated twice and the sub-band 3 is repeated twice, n SRS The number of SRS transmissions is counted in the order of 0, 0, 1, 1, and so on.

[0052] In one embodiment, the rule agreed with the second communication node includes at least one of the following: the number of times that a periodic SRS or a semi-persistent SRS is repeated in the time domain or between slots is the ratio of the hopping bandwidth to the multiple transmission bandwidth, wherein the multiple transmission bandwidth is the product of the transmission bandwidth and the number of different transmission positions in the frequency domain; when the frequency domain position of the SRS is located at a frequency domain position where the SRS cannot be transmitted, or when the frequency domain position of the SRS completely or partially overlaps with the frequency domain of other signals, the SRS frequency domain position at the current time domain position is updated to the frequency domain position corresponding to the time domain position of the last SRS transmission; when the frequency domain position of the SRS is located at a frequency domain position where the SRS cannot be transmitted, or when the frequency domain position of the SRS completely or partially overlaps with the frequency domain of other signals, the SRS frequency domain position at the current time domain position is updated to the frequency domain position corresponding to the time domain position of the next SRS transmission; when the frequency domain position of the SRS is located at a frequency domain position where the SRS cannot be transmitted, or when the frequency domain position of the SRS completely or partially overlaps with the frequency domain of other signals, the number of SRS transmissions is not accumulated; when the frequency domain position of the SRS is located at a frequency domain position where the SRS cannot be transmitted, or when the frequency domain position of the SRS completely or partially overlaps with the frequency domain of other signals, the number of SRS transmissions is N, wherein N is an integer greater than or equal to 2 and less than or equal to 10;

[0053] In the case of aperiodic SRS, the number of SRS transmissions n SRS is calculated as follows: wherein l' is the orthogonal frequency division multiplexing, OFDM, symbol number within the SRS resource, R is a repetition factor configured by the first communication node through a higher layer parameter, and R partial is a factor configured by the first communication node through a higher layer parameter for indicating repetition between SRS resources or SRS resource sets or between SRS transmission slots, SRS In the case of periodic SRS or semi-persistent SRS, the number of SRS transmissions n

[0054]

[0055] wherein l' is the orthogonal frequency division multiplexing, OFDM, symbol number within the SRS resource, R is a repetition factor configured by the first communication node through a higher layer parameter, and R partial is a factor configured by the first communication node through a higher layer parameter for indicating repetition between SRS resources or SRS resource sets or between SRS transmission slots, The continuous OFDM symbols occupied by SRS resources, The number of time slots per frame with subcarrier spacing configured as μ, n f is the system frame number, is the time slot number in the frame with subcarrier spacing configured as μ, T SRS is the time slot period of SRS, T offset The time slot offset of SRS; the transmit comb offset of SRS is obtained based on at least one of the following parameters: symbol or time slot index, frequency domain subband or frequency band index, cell ID or UE ID, SRS transmission number n SRS In this embodiment, when the frequency domain position of the SRS is located at a frequency domain position where the SRS cannot be sent, for example, when the current time domain position is occupied, the frequency domain position of the SRS at the current time domain position can be updated to the frequency domain position corresponding to the time domain position of the last time SRS transmission, or the frequency domain position of the SRS at the current time domain position can be updated to the frequency domain position corresponding to the time domain position of the next time SRS transmission, thereby avoiding interference with adjacent cells. The schematic diagram of updating the frequency domain position of the SRS at the current time domain position to the frequency domain position corresponding to the time domain position of the last time SRS transmission can be found in the attached figure. Figure 4 ,like Figure 4 As shown, Figure 4 The a region in FIG is used to show that a conventional UE sends SRS on subbands 1-4. Figure 5 The b area in FIG. 1 is used to illustrate that the UE in the embodiment of the present disclosure does not transmit the SRS in subband 3, but repeatedly transmits the SRS in subband 1. In this case, the number of SRS transmissions is counted cumulatively in the order of 0, 0, 2, 3, ...; the schematic diagram of updating the SRS frequency domain position at the current time domain position to the frequency domain position corresponding to the time domain position of the next SRS transmission can be found in the attached FIG. Figure 5 ,like Figure 5 As shown, Figure 5 The a region in FIG is used to show that a conventional UE sends SRS on subbands 1-4. Figure 6 Area b in the figure is used to show that the UE in the embodiment of the present disclosure does not send SRS in subband 3, but repeatedly sends SRS in subband 2. In this case, the number of SRS transmissions is accumulated and counted in the order of 0, 2, 2, 3, ...

[0056] In the embodiment, in the case of non-periodic SRS, the coverage of SRS can be enhanced by introducing partial frequency hopping in aperiodic SRS resource, assuming that all symbols in a slot can be used for SRS transmission, supporting that each SRS resource contains 8 symbols and the repetition factor R=2. If R=4 is configured, according to the existing standard protocol, the frequency domain needs to be occupied, and the hopping bandwidth configured by RRC in the resource can only achieve the frequency hopping pattern shown in the b area of Figure 7 . After introducing partial frequency hopping in aperiodic SRS resource, SRS can be transmitted in part of the sub-band, and the frequency hopping pattern shown in the b area of Figure 7 can be achieved. Compared with the b area in Figure 6 and the b area in Figure 7 , it can be seen that the frequency domain bandwidth of the b area in Figure 7 is half of the frequency domain bandwidth of the b area in Figure 9 . When the transmission power is the same, the smaller the frequency domain bandwidth is, the greater the transmission energy will be, and the larger the coverage will be.

[0057] In an exemplary embodiment, the transmission comb offset of the SRS can be based on the transmission number n SRS of the SRS, including the transmission comb offset of the SRS transmitted on the p i th antenna port :

[0058]

[0059] wherein is the SRS transmission comb offset configured by the first communication node through a high-level parameter, n SRS is the transmission number of the SRS, K TC is the number of transmission combs, is the cyclic shift of the SRS sequence, is the maximum number of cyclic shifts of the SRS sequence, The number of antenna ports for SRS. In the present embodiment, for Rel-17 SRS enhancement, as the number of transmission combs of SRS increases, the transmission power of SRS will also be further increased, which will bring great inter-cell interference if there is no cooperation of SRS related information between cells. Therefore, it can be considered that the comb offset of SRS changes with frequency hopping within the aperiodic SRS resource, so as to achieve the purpose of interference randomization. That is, since the comb offset changes, the carrier used to transmit SRS will also change accordingly, so the transmission comb offset associated with the transmission mode can be determined first, the carrier used to transmit SRS is determined based on the comb offset, and SRS is transmitted on the carrier. Wherein, the comb offset can be associated with symbol / slot index or frequency domain sub-band or frequency band index, cell ID or UE ID for randomization.

[0060] In the foregoing embodiment, the number of SRS transmissions when the SRS frequency domain hops is calculated, the SRS is repeatedly transmitted in a certain frequency band by reducing the SRS transmission bandwidth, so as to enhance the coverage and multiplexing capacity of the SRS, and reduce the interference to the adjacent cell; when the SRS encounters a frequency domain sub-band that is not transmitted, the SRS is repeatedly transmitted in the previous frequency domain sub-band or the following frequency domain sub-band at this time domain position, solving the problem of mutual conflict between SRS frequency hopping and other user or other service data.

[0061] Through the above description of the embodiments, those skilled in the art can clearly understand that the method according to the above embodiments can be realized by means of software and the necessary general hardware platform, of course, it can also be realized by hardware, but in many cases the former is a better embodiment. Based on such understanding, the technical solutions of the present disclosure can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk) and includes a plurality of instructions for making a terminal device (which can be a mobile phone, computer, server, or network device, etc.) execute the methods described in various embodiments of the present disclosure.
