Description

TECHNICAL FIELD

[0001] The present application relates to the field of wireless communication, and particularly relates to a configuration method for information transmission, an electronic device and a storage medium. BACKGROUND

[0002] Multi-Transmission and Reception Point (Multi-TRP) joint transmission technology uses multiple Transmission and Reception Points (TRPs) to transmit in the Long Term Evolution (LTE) in the enhanced Mobile Broadband (eMBB) scenario, so that the transmission throughput in Long Term Evolution-Advanced (LTE-A) and New Radio Access Technology (NR) is effectively improved. Another technology of NR is Multi-Panel transmission, which uses multiple antenna panels for transmission to obtain higher spectral efficiency. At the same time, the transmission reliability of the communication system must also be guaranteed, and the transmission or reception using Multi-TRP or Multi panel can effectively reduce the probability of information blocking, thereby effectively improving the transmission reliability in the Ultra-reliable and Low Latency Communications (URLLC) scenario. However, in the prior art, there are still some problems to be solved in the multiple transmissions in Multi-TRP or Multi panel. In the multi-TRP scenario, due to the different positions of different TRPs relative to the terminal UE, the propagation paths are different, as shown in the schematic diagram in FIG. 1. When two TRPs transmit data respectively, due to the problem of the propagation path, there is a time delay in the UE receiving, and when the transmission time of TRP0 to the UE is greater than the transmission time of TRP1 to the UE, the UE may receive data overlap, as shown in FIG. 2. In FIG. 2, due to the long propagation distance of TRP0, the time delay of the UE receiving is large, while the propagation distance of TRP1 is short, and the time delay is small. At this time, the data of TRP0 and the data of TRP1 overlap in the time domain of the UE receiving, thereby affecting the UE receiving. When the UE transmits data to two TRPs respectively, due to the different TA of different TRPs, the UE has different advance times for transmitting information to different TRPs, which may cause overlap in the UE uplink transmission, as shown in FIG. 3. Figure 1 Figure 2a Figure 2a Figure 2b ​​​The figure is shown in the attached Figure 2b Since the TA0 corresponding to the TRP0 is small, the information sent by the UE to the TRP0 needs to be advanced by a small amount, and the TA1 corresponding to the TRP1 is large, the information sent by the UE to the TRP1 needs to be advanced by a large amount. For two pieces of information that are adjacent on the receiving side of the TRP, there will be an overlap in the time domain at the UE sending end. SUMMARY

[0037] It should be understood that the specific embodiments described herein merely exemplify the application and should not be used to limit the application.

[0038] In the following description, the suffix used for an element such as "module", "part", or "unit" is used only for convenience of explanation of the present application, and has no particular meaning by itself. Thus, "module", "part", or "unit" can be mixedly used.

[0039] Figure 3 is a flowchart of a configuration method for information transmission in embodiments of the present application, which can be applied to the case of multiple transmissions of downlink data. The method can be executed by a configuration device for information transmission in embodiments of the present application, which can be implemented in software and / or hardware, and is generally integrated in a first transmission node, such as a base station. Referring to Figure 3 The method provided by the embodiments of the present application specifically includes the following steps:

[0040] In step 110, a transmission interval K between each downlink transmission is configured in the case of continuous transmission of downlink information for at least twice.

[0041] The downlink information can be data or control signaling sent by the first transmission node to the second transmission node, for example, data or indication information sent by a base station to a user terminal in NR. The transmission interval K can be a transmission interval between downlink transmissions, and can specifically include a symbol or time.

[0042] In the embodiments of the present application, when multiple downlink transmissions are performed, one transmission interval can be configured so that the downlink data of each transmission does not overlap with each other during transmission. It can be understood that the transmission interval K can be a preset fixed value or an interval value determined according to the network state.

[0043] In the embodiments of the present application, when multiple downlink transmissions are performed, one transmission interval K is configured for the transmission of downlink data, so that the downlink transmission is sent according to the transmission interval K. According to the transmission interval, the overlap probability of multiple transmissions in the multi-TRP scenario is reduced, the communication interference is reduced, and the network quality of wireless communication is enhanced.

[0044] Further, in the NR scenario, two application scenarios are included: a single-downlink control signaling (S-DCI) scenario and a multi-downlink control signaling (M-DCI) scenario.

[0045] Further, on the basis of the above-mentioned embodiments, the configuration of the transmission interval K between each downlink transmission includes: in the single-downlink control signaling scenario, the transmission interval K is configured between each two downlink transmissions.

[0046] In the embodiments of the present application, the transmission interval K can be configured between each two downlink transmissions.

[0047] Exemplarily, Figure 4 is an example diagram of a configuration method for information transmission in the embodiments of the present application, referring to Figure 4 When K is one OFDM symbol, the data length sent by the two TRPs is 4 OFDM symbols, and the data is cyclically repeated four times. The transmission delay of TRP0 is less than that of TRP1. The first transmission from TRP1 occupies the 0-3 symbols of slot 0; the second transmission from TRP1 occupies the 5-8 symbols of slot 0; the third transmission from TRP0 occupies the 10-13 symbols of slot 0; and the fourth transmission from TRP0 occupies the 1-4 symbols of slot 1.

[0048] Further, on the basis of the above application embodiment, the transmission interval K between each downlink transmission is configured, including: in the scenario of single downlink control signaling, the transmission interval K is configured between two downlink transmissions in which transmission receiving node TRP or transmission configuration indication TCI state switching occurs.

[0049] Specifically, the transmission interval K is only configured between two downlink transmissions in which TRP switching or TCI state switching occurs, for example, after downlink transmission a is executed, TRP or TCI switching occurs, and then downlink transmission b is executed, the transmission interval K is configured between downlink transmission a and downlink transmission b.

[0050] In an exemplary embodiment, Figure 5 is an example diagram of another configuration method for information transmission in the application embodiment, referring to Figure 5 When the downlink data is repeatedly transmitted multiple times, the base station configures a transmission interval K for the downlink transmission, which is used between two transmissions in which TRP / TCI switching occurs, when K is an OFDM symbol, the data length transmitted by the two TRPs is 4 OFDM symbols, and the cyclic repetition transmission is four times, the transmission time of TRP0 is less than the transmission time delay of TRP1, and the transmission starts from TRP1. The first transmission from TRP1 occupies 0-3 symbols of slot 0; the second transmission from TRP1 occupies 4-7 symbols of slot 0; the third transmission from TRP0 occupies 9-12 symbols of slot 0; and the fourth transmission from TRP0 occupies 13 symbols of slot 0 and 0-2 symbols of slot 1.

[0051] Further, on the basis of the above application embodiment, the transmission interval K between each downlink transmission is configured, including: in the scenario of single downlink control signaling, the transmission interval K is configured after the downlink transmission transmitted by the target TRP, and between two downlink transmissions in which TRP or TCI state switching occurs.

[0052] Wherein, the target TRP can be a selected TRP, which can be a TRP selected according to a configuration parameter, or a TRP satisfying a transmission delay condition.

[0053] In the application embodiment, the transmission interval K can be configured between two downlink transmissions in which TRP or TCI state switching occurs, and only after the downlink transmission of the target TRP, for example, it is judged whether the next transmission after the downlink transmission of the target TRP occurs TRP or TCI state switching, if yes, the transmission interval K is configured after the downlink transmission, if not, no configuration is performed.

[0054] Further, on the basis of the above application embodiment, the target TRP is a TRP with the maximum transmission delay among the plurality of TRPs, and the value of the transmission interval K is associated with at least one of the following information: the TCI state of the target TRP and the target timing advance, the target timing advance being a timing advance corresponding to the maximum timing advance value among the plurality of TRPs.

[0055] The timing advance can be information used to indicate the downlink data transmission time.

[0056] In an exemplary embodiment, Figure 6 is an example diagram of another configuration method for information transmission in the embodiment of the application, referring to Figure 6 When K is one OFDM symbol, the data length of the two TRPs is four OFDM symbols, and the transmission is repeated alternately four times, the transmission time of TRP0 is less than the transmission delay of TRP1, and the transmission starts from TRP1, the first transmission from TRP1 occupies the 0-4 symbols of slot 0, symbol 4 is configured as a transmission interval; the second transmission from TRP0 occupies the 5-8 symbols of slot 0; the third transmission from TRP1 occupies the 9-13 symbols of slot 0, symbol 13 is configured as a transmission interval; the fourth transmission from TRP0 occupies the 0-3 symbols of slot 1.

[0057] Further, on the basis of the above application embodiment, the transmission interval K between each downlink transmission is configured, including: in the case of single downlink control signaling, the transmission interval K is configured before the downlink transmission sent by the target TRP, and between the two downlink transmissions in which TRP or TCI state switching occurs.

[0058] In the embodiment of the application, the transmission interval K can be configured between the two downlink transmissions in which TRP or TCI state switching occurs, and only before the downlink transmission of the target TRP, for example, judging whether the downlink transmission of the target TRP relative to the last downlink transmission has TRP or TCI state switching, if yes, the transmission interval K is configured before the downlink transmission, if not, no configuration is performed.

[0059] Further, on the basis of the above application embodiment, the target TRP is a TRP with the maximum transmission delay among the plurality of TRPs, and the value of the transmission interval K is associated with at least one of the following information: the TCI state of the target TRP and the target timing advance, the target timing advance being a timing advance corresponding to the maximum timing advance value among the plurality of TRPs.

[0060] Exemplarily, Figure 6 is an example diagram of another configuration method for information transmission in the embodiment of the application, referring to Figure 6When K is one OFDM symbol, the data length of two TRPs is four OFDM symbols, and the transmission is repeated four times alternately, the transmission time delay of TRP0 is less than that of TRP1, and the transmission starts from TRP1, the first transmission from TRP1 occupies 0-3 symbols of slot 0; the second transmission from TRP0 occupies 4-8 symbols of slot 0, symbol 4 is configured as a transmission interval; the third transmission from TRP1 occupies 9-12 symbols of slot 0; the fourth transmission from TRP0 occupies symbol 13 of slot 0 and 0-3 symbols of slot 1, symbol 13 is configured as a transmission interval.

[0061] Further, on the basis of the above-mentioned application embodiment, the transmission interval K between the configurations of each downlink transmission comprises: in the case of single downlink control signaling, when two downlink transmissions are performed, the downlink transmission with smaller transmission time delay is transmitted before the downlink transmission with larger transmission time delay.

[0062] Specifically, when two downlink transmissions are performed, the information of the two downlink transmissions can be the same or different, and when the transmission order of the downlink transmission is configured, the downlink transmission with smaller transmission time delay is transmitted before the downlink transmission with larger transmission time delay. Further, when the downlink information of the two downlink transmissions is different, the data with smaller transmission time delay is transmitted first and the data with larger transmission time delay is transmitted later, and at this time, the transmission interval K does not need to be configured.

[0063] Exemplarily, Figure 7 is an example diagram of another configuration method for information transmission in the application embodiment, referring to Figure 7 , the data length of two TRPs is four OFDM symbols, the transmission contents are the same or different, the transmission time delay of TRP0 is less than that of TRP1, and the transmission starts from TRP0, the data of TRP0 occupies 0-3 symbols of slot 0; the data of TRP1 occupies 4-7 symbols of slot 0, and the data of two TRPs will not overlap when received by the UE.

[0064] When the backhaul between the cooperating TRPs is not ideal, the backhaul delay between the cooperating TRPs is slightly large. Since the interaction of 2 TRPs can have a delay, it is difficult to share one PDCCH, so the scheduling of 2 TRPs can be independently scheduled. Two TRPs independently schedule and transmit DCI to schedule data, which is called multi-downlink control signaling DCI (multi-DCI, M-DCI) M-TRP.

[0065] Further, on the basis of the above application embodiment, the transmission interval K between each downlink transmission is configured, including: in the scene of multiple downlink control signaling, the transmission interval K is configured before the downlink transmission of the target TRP and between the two downlink transmissions in which the TRP or TCI state switching occurs.

[0066] In the embodiment of the application, the transmission interval K can be configured between the two downlink transmissions in which the TRP or TCI state switching occurs, and only before the downlink transmission of the target TRP, for example, it is judged whether the downlink transmission of the target TRP relative to the last transmission has the TRP or TCI state switching, if yes, the transmission interval K is configured before the downlink transmission, if not, no configuration is performed.

[0067] Further, on the basis of the above application embodiment, the target TRP is the TRP with the smallest transmission delay among the TRPs, and the value of the transmission interval K is associated with at least one of the following information: the TCI state of the target TRP, the target timing advance value and the target high-layer parameter CORESTPoolIndex, wherein the target timing advance is the timing advance corresponding to the smallest timing advance value among the TRPs, and the target high-layer parameter is the CORESTPoolIndex value corresponding to the TRP with the smallest transmission delay among the TRPs.

[0068] In an exemplary embodiment, Figure 8 is an example diagram of another configuration method for information transmission in the embodiment of the application, referring to Figure 8 When K is one OFDM symbol, the data length of TRP0 is 4 OFDM symbols, the data length of TRP1 is 2 OFDM symbols, the transmission time of TRP0 is less than the transmission time of TRP1, the transmission is started by TRP1, and the data of TRP1 occupies the 0-3 symbols of slot 0; the data of TRP1 occupies the 4-6 symbols of slot 0, and symbol 4 is configured as a transmission interval.

[0069] Further, on the basis of the above application embodiment, the transmission interval K between each downlink transmission is configured, including: in the scene of multiple downlink control signaling, the transmission interval K is configured after the downlink transmission of the target TRP and between the two downlink transmissions in which the TRP or TCI state switching occurs.

[0070] In the embodiment of the application, the transmission interval K can be configured between the two downlink transmissions in which the TRP or TCI state switching occurs, and only after the downlink transmission of the target TRP, for example, it is judged whether the next transmission after the downlink transmission of the target TRP has the TRP or TCI state switching, if yes, the transmission interval K is configured after the downlink transmission, if not, no configuration is performed.

[0071] Further, on the basis of the above application embodiment, the target TRP is the TRP with the maximum transmission delay in each TRP, and the value of the transmission interval K is associated with at least one of the following information: a TCI state of the target TRP, a target timing advance, and a target high-layer parameter CORESTPoolIndex, wherein the target timing advance is a timing advance corresponding to the maximum timing advance value in each TRP, and the target high-layer parameter is a CORESTPoolIndex value corresponding to the TRP with the maximum transmission delay in each TRP.

[0072] In an exemplary embodiment, Figure 8 is an example diagram of another configuration method for information transmission in the application embodiment, referring to Figure 8 When K is one OFDM symbol, the data length of TRP1 is 4 OFDM symbols, the data length of TRP0 is 2 OFDM symbols, the transmission delay of TRP0 is greater than that of TRP1, and TRP1 starts to send, the data of TRP1 occupies 0-4 symbols of slot 0, and symbol 4 is configured as a transmission interval; the data of TRP0 occupies 5-6 symbols of slot 0.

[0073] Further, on the basis of the above application embodiment, the configuration of the transmission interval K between each downlink transmission comprises: in the scenario of multiple downlink control signaling, when two downlink transmissions are performed, the downlink transmission with a smaller transmission delay is sent before the downlink transmission with a larger transmission delay.

[0074] Specifically, when two downlink transmissions are performed, the downlink information of the two downlink transmissions can be the same or different, and when the transmission order of the downlink transmission is configured, the downlink transmission with a smaller transmission delay is sent before the downlink transmission with a larger transmission delay, and at this time, the transmission interval K does not need to be configured.

[0075] Exemplarily, referring to Figure 9 When K is one OFDM symbol, the data length of TRP0 is 4 OFDM symbols, the data length of TRP1 is 2 OFDM symbols, the transmission delay of TRP0 is less than that of TRP1, and TRP0 starts to send, the data of TRP0 occupies 0-1 symbols of slot 0; the data of TRP1 occupies 2-5 symbols of slot 0, and no transmission interval K is set between TRP0 and TRP1, and the data of the two TRPs will not overlap when received by the UE.

[0076] Further, on the basis of the above application embodiment, the configuration of the transmission interval K between each downlink transmission comprises: in the scenario of multiple downlink control signaling, when at least two downlink transmissions are performed, the downlink transmissions from the two TRPs are not configured to be sent in close proximity.

[0077] In the embodiments of the present application, when downlink transmission is performed from two TRPs, an interval is configured between downlink transmission from different TRPs, and the downlink transmission is not sent immediately next to each other.

[0078] Further, on the basis of the above-mentioned embodiments, the transmission interval K is an interval time or an interval symbol number determined according to the timing advance value or the transmission delay.

[0079] Specifically, the unit of the transmission interval K can be an interval time or a transmission symbol, and the value of the transmission interval K can be determined by the timing advance value.

[0080] Exemplarily, Figure 10 is an example diagram of a transmission interval K in the embodiments of the present application, referring to Figure 10 When the transmission interval K is an interval time, the base station calculates the interval time T = |TA1-TA0| according to the timing advance value, and indicates the time interval K = T. As shown in Figure 10 , the UE simultaneously maintains two time axes corresponding to TRP0 and TRP1, when the TRP0 with small transmission delay is switched to the TRP1 with large transmission delay, the starting symbol of the transmission corresponding to the TRP1 is: the last symbol of the TRP0 + T corresponding to the nearest symbol on the time axis of the TRP1. The time axis 1 completes the first transmission at symbols 0-3, and symbol 3+T corresponds to symbol 4 of the time axis 2, therefore, the starting symbol of the second transmission is symbol 5 of the time axis 2.

[0081] In another exemplary embodiment, the base station calculates the interval time T = |TA1-TA0| according to the timing advance value, judges the required interval OFDM symbol number K according to the time interval T, and indicates the interval symbol K to the UE. Wherein, K is the upward rounding of the time interval T to the symbol duration.

[0082] Further, on the basis of the above-mentioned embodiments, when at least two downlink transmissions are performed, no transmission interval K is configured, and if it is judged that the reception of the second transmission node will overlap, the information length of the downlink transmission of the first transmission node in the overlapping part is shortened.

[0083] Specifically, when the first transmission node performs continuous at least two downlink transmissions, if no transmission interval K is configured in the first transmission node, the first transmission node can judge whether the uplink transmission of the second transmission node will overlap in reception, and if it is judged that the overlap will occur, the information length of the downlink transmission of the first transmission node in the overlapping part as the sending end is shortened.

[0084] In the embodiments of the present application, when there is overlap in the data sent by the first transmission node of different transmission paths, the length of the data in the overlapping part can be shortened. For example, the length of the information of one of the downlink transmissions in the overlapping part can be shortened randomly, and the length of the information of the other downlink transmission can be kept unchanged.

[0085] Further, on the basis of the above-mentioned embodiments, the shortening of the length of the information of the downlink transmission in the overlapping part includes at least one of the following: shortening the length of the information of the downlink transmission of the later transmission of the two transmissions in the overlapping part; shortening the length of the information of the downlink transmission of the earlier transmission of the two transmissions in the overlapping part; shortening the length of the information of the downlink transmission of the lower-priority transmission of the two transmissions in the overlapping part; and shortening the length of the information of the downlink transmission of the different TRPs in the overlapping part in turn.

[0086] In the embodiments of the present application, the length of the information of the downlink transmission of the later transmission of the two transmissions in the overlapping part can be shortened, and the length of the information of the downlink transmission of the earlier transmission is not changed, Figure 11 is an example diagram of the shortening of the length of the information in the embodiments of the present application. Referring to Figure 11 , TRP1 transmits the downlink transmission earlier than TRP0, and the length of the information of the downlink transmission of TRP0 is shortened. The length of the information of the downlink transmission of the earlier transmission of the two transmissions in the overlapping part can also be shortened, Figure 12 is another example diagram of the shortening of the length of the information in the embodiments of the present application. Referring to Figure 12 , TRP1 transmits the downlink transmission earlier than TRP0, and the length of the information of the downlink transmission of TRP1 is shortened. The length of the information can also be shortened according to the priority, for example, the main TRP is TRP0, and the priority of the downlink information transmitted by TRP0 is relatively high. The downlink information corresponding to TRP1 can be shortened, and the overlapping symbol corresponding to TRP1 is shortened, as shown in Figure 12 . The length of the information of the downlink transmission of the different TRPs in the overlapping part can also be shortened in turn. TRP1 and TRP0 overlap, TRP1 shortens the length of the information of the downlink transmission when the overlap occurs for the first time, and TRP0 transmits normally. When the overlap occurs for the second time, TRP1 transmits normally, and TRP0 shortens the length of the information of the downlink transmission, as shown in Figure 13 .

[0087] Figure 14 is a flowchart of another configuration method for information transmission in the embodiments of the present application. The embodiments of the present application can be applied to the case of multiple transmissions of downlink data. The method can be executed by the configuration device for information transmission in the embodiments of the present application, which can be realized by software and / or hardware, and is generally integrated in the second transmission node, for example, a user terminal UE. Referring to Figure 14 , the method provided by the embodiments of the present application specifically includes the following steps:

[0088] Step 210, in the case of continuous transmission of at least two uplink information, configure the transmission interval K between each uplink transmission.

[0089] Wherein, the uplink information can be data or control information sent by the first transmission node to the second transmission node, for example, data or indication information sent by the user end to the base station in NR. The transmission interval K can be the transmission interval between uplink transmissions, which can specifically include symbols or time, etc.

[0090] In the embodiments of the present application, when multiple uplink transmissions are performed, one transmission interval can be configured so that the uplink data of each transmission does not overlap with each other when transmitted. It can be understood that the transmission interval K can be a preset fixed value or an interval value determined according to the network state.

[0091] In the embodiments of the present application, when multiple uplink transmissions are performed, one transmission interval K is configured for the transmission of uplink data, which is used for multiple uplink transmissions. According to the transmission interval, the overlap probability of multiple data transmissions in the multi-TRP scenario is reduced, the communication interference is reduced, and the network quality of wireless communication is enhanced.

[0092] Further, in the NR scenario, there are two application scenarios: single downlink control signaling (Single-Downlink Control Information, S-DCI) scenario and multi downlink control signaling (Multi-Downlink Control Information, M-DCI) scenario.

[0093] Further, on the basis of the above application embodiments, the configuration of the transmission interval K between each uplink transmission includes: in the single downlink control signaling scenario, the transmission interval K is configured between each two uplink transmissions.

[0094] In the embodiments of the present application, the transmission interval K can be configured between each two uplink transmissions.

[0095] Exemplarily, Figure 15 is an example diagram of a configuration method for information transmission in the embodiments of the present application, see Figure 15When K is one OFDM symbol, the uplink data length sent to the two TRPs is four OFDM symbols, and the transmission is repeated four times in sequence, TA0 corresponding to TRP0 is less than TA1 corresponding to TRP1, the first uplink transmission is sent to TRP0 occupying 0-3 symbols of slot 0; the second transmission is sent to TRP0 occupying 5-8 symbols of slot 0; the third transmission is sent to TRP1 occupying 10-13 symbols of slot 0; and the fourth transmission is sent to TRP1 occupying 1-4 symbols of slot 1.
