Those skilled in the art will appreciate that with the evolution of communication systems and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are equally applicable to similar technical problems.

[0043] like Figure 1b As shown in the structural diagram of the terminal 101, the terminal 101 provided in the embodiment of the present application includes a processor 210, a memory 220, a communication interface 230, and one or more programs 221, wherein the one or more programs 221 are stored in the memory 220 and are configured to be executed by the processor 210, and the program 221 includes a program for executing the operations performed by the device on the user device side in the method described in the embodiment of the method of the present application.

[0045] See also Figure 2a , Figure 2a 1 is a flow chart of a joint channel estimation method provided by an embodiment of the present application. As shown in the figure, the method includes:

[0046] Step 201: The terminal receives time information sent from a network device, where the time information is used to indicate a preset time period, and the preset time period is within a time period corresponding to a plurality of time windows.

[0047] Among them, the time information includes information of a time window configured by the network device, and the time window refers to a time period for joint channel estimation, that is, under normal circumstances, the time information corresponding to a time window is the time information corresponding to a joint channel estimation. Specifically, the PUSCH transmission within the time window needs to ensure the phase continuity and / or power consistency of the transmission. The time information may include information of multiple time windows, and these time windows may overlap in time or these time windows may be independent in time. Therefore, the specific time for joint channel estimation can be determined in the time period corresponding to these time windows according to the time information. The preset time period may be all the time periods in the time periods corresponding to these time windows, or part of the time periods in the time periods corresponding to these time windows. In a specific implementation, the preset time period may also be used to indicate the rules for joint channel estimation performed by the terminal or network device within the preset time period, that is, the start time, end time and number of joint channel estimations of each time window may be obtained through the preset time period, and the relevant content of the preset time period may be that the time information is reflected through downlink control information (Downlink Control Information, DCI) or radio resource control (Radio Resource Control, RRC) or MAC layer control information (MAC-CE). Of course, the time information may also include only the start time and end time of a certain type of time window, and other information of this type of time window may be determined by the number of repetitions and interval time of the corresponding time window in the time information. Among them, when the preset time period includes multiple time windows, the time lengths of these multiple time windows may be different. Alternatively, the time information may be embodied in an implicit manner, for example, determined by the number of PUSCH retransmissions indicated in the DCI or RRC. For example, if the DCI indicates that the PUSCH is to be retransmitted 4 times, the length of the time window of the time information may include the 4 PUSCH transmissions. A specific example is that the time window may start at the first OFDM symbol of the first PUSCH transmission or the first OFDM symbol of the time slot where the first PUSCH transmission is located, or the last OFDM symbol of the PDCCH carrying the DCI, or the OFDM symbol after the last OFDM symbol of the PDCCH carrying the DCI. The time window may also end at the last OFDM symbol of the last PUSCH transmission, or the last OFDM symbol of the time slot where the last PUSCH transmission is located. It should be noted that the PUSCH in this solution can be replaced by a physical uplink control channel (Physical Uplink Control Channel, PUCCH).

[0048] In a possible example, when the multiple time windows overlap in time, the preset time period is the union of time periods corresponding to the multiple overlapping time windows.

[0049] Among them, the network device will configure multiple time windows for joint channel estimation, but the time windows configured by the network device may overlap in time, that is, the time period corresponding to a certain time window may partially or completely overlap with the time period corresponding to other time windows. At this time, the preset time period is determined to be the union of the time periods corresponding to the multiple overlapping time windows, that is, the time that can be used for channel estimation is determined to be the union of the time periods corresponding to the multiple overlapping time windows, that is, PUSCH transmissions in all time periods corresponding to the multiple overlapping time windows can be used for joint channel estimation. Figure 2b As shown, Figure 2b This is a schematic diagram of a joint channel estimation time provided in an embodiment of the present application. In the figure, time window 1 and time window 2 overlap, and the preset time period at this time is all the time periods corresponding to time window 1 and time window 2.

[0050] In a specific implementation, after determining that the preset time period is the union of time periods corresponding to multiple overlapping time windows, the number of joint channel estimations within the preset time period and the start and end time of each joint channel estimation may also be determined. Figure 2b It can be determined that the number of joint channel estimations within the preset time period is 1. Since the phase continuity of the terminal needs to be maintained when performing joint channel estimation, that is, the phase-related parameters in each PUSCH within the preset time period need to be consistent, it is necessary to determine a standard time window so that the phase-related parameters in other time windows included in the preset time period are consistent with the phase-related parameters in the standard time window. Among them, the standard time window can be the earliest time window among multiple overlapping time windows. For example, the beam direction corresponding to time window 1 is A, and the beam direction corresponding to time window 2 is B. At this time, since the joint channel estimation is only performed once within the preset time period, and time window 1 is a standard time window, the beam direction corresponding to time window 2 needs to be changed to A. For example Figure 2b It can also be determined that the number of joint channel estimations in the preset time period is 2. Therefore, when the preset time period includes multiple time windows, the number of joint channel estimations can be determined according to the number of time windows, and specifically, the number of joint channel estimations is the same as the number of time windows.

[0051] In a specific implementation, when a preset time period includes multiple time windows, each time window is sorted according to the start time in the preset time period, and the first time window is the time window with the earliest start time, and so on. The time period corresponding to the first time window can be first determined as a joint channel estimation time, and the time period corresponding to the second time window overlapping with the first time window, except the time period overlapping with the first time window, is another joint channel estimation time, and then the time period corresponding to the third time window except the time period overlapping with the second time window is determined as another joint channel estimation time, and so on. For example, time window 1 overlaps with time window 2, and time window 2 overlaps with time window 3. At this time, the time period corresponding to time window 1 can be determined as a time period for a joint channel estimation, and the time period corresponding to time window 2 that does not overlap with time window 1 is a time period for another joint channel estimation. At this time, the time period corresponding to time window 3 that does not overlap with time window 2 is another time period for joint channel estimation.

[0052] If there are multiple time windows overlapping with the first time window, the time window with the longest time period that does not overlap with the time period corresponding to the first time window in the time periods corresponding to the multiple time windows is determined as the target time window, and the time period except the time period overlapping with the first time window in the time period corresponding to the target time window is determined as another joint channel estimation time. If there are other time windows overlapping with the target time window, the time window with the longest time period that does not overlap with the time period corresponding to the first time window in the time period corresponding to the time window overlapping with the target time window is determined as another target time window, and so on, the number of joint channel estimations within the preset time period and the start and end time of each time are determined. For example, time window 1 overlaps with time window 2 and time window 3 respectively, and the time period in time window 3 that does not overlap with time window 1 is greater than the time period in time window 2 that does not overlap with time window 1. At this time, it can be determined that the time period corresponding to time window 1 is the time period of one joint channel estimation, and the time period corresponding to time window 3 is the time of another joint channel estimation.

[0053] It can be seen that in this example, when multiple time windows overlap, the union of the time periods corresponding to the multiple time windows is determined as the time for joint channel estimation, which can clarify the time for joint channel estimation and improve the efficiency of channel estimation.

[0054] In a possible example, when the overlapping situation is that the multiple time windows overlap in time, the preset time period is a time period corresponding to the time window with the earliest start time among the multiple overlapping time windows.

[0055] When multiple time windows overlap, it can be determined that the time period that can be used for joint channel estimation is the time period corresponding to the time window with the earliest start time. Figure 2c As shown, Figure 2cis a schematic diagram of another joint channel estimation time provided by an embodiment of the present application, in Figure 2c In the example, time window 1 and time window 2 overlap each other. At this time, since the start time of time window 1 is earlier than the start time of time window 2, the preset time period is the time period corresponding to time window 1.

[0056] In a specific implementation, the time window with the earliest start time can be the one with the earliest start time among multiple overlapping time windows, or the one with the earliest start time among two overlapping time windows. That is, according to the start time sorting, if time window 1 overlaps with time window 2, time window 2 overlaps with time window 3, and time window 4 overlaps with time window 3, all time windows are compared with each other to determine a time window with the earliest start time, then the time window with the earliest start time is time window 1, so the preset time period is the time period corresponding to time window 1. It is also possible to compare two overlapping time windows separately according to the start time, and the time windows that have been compared will no longer participate in the comparison, and so on, to obtain multiple time windows with the earliest start times. That is, time window 1 is compared with time window 2, because time window 2 has already participated in the comparison, then time window 3 is compared with time window 4 at this time, and time window 1 and time window 3 with earlier start times are obtained.

[0057] In a specific implementation, if multiple time windows overlap with each other, the time period corresponding to the first time window is determined to be the first preset time period, the first time window is the time window with the earliest start time, the second time window overlapping with the first time window is determined to be invalid, the time period corresponding to the third time window overlapping with the second time window is determined to be the second preset time period, and both the first preset time period and the second preset time period can be used for joint channel estimation, and so on, to determine multiple preset time periods that can be used for joint channel estimation. Among them, if the third time window includes multiple, the time window with the longest time period that does not overlap with the second time window in the time period corresponding to the third time window is determined to be the third target time window, and the time period corresponding to the third target time window is determined to be the second preset time period. Alternatively, if the third time window includes multiple, the time window with the earliest start time in the time period corresponding to the third time window is determined to be the third target time window, and the time period corresponding to the third target time window is determined to be the second preset time period. After determining the third target time window, it is determined that other time windows in the third time window except the third target time window are invalid.

[0058] In a specific implementation, the time period corresponding to the time window with the longest time span among the multiple overlapping time windows may also be determined as the preset time period.

[0059] It can be seen that in this example, the time period corresponding to the time window with the earliest start time among the multiple overlapping time windows is determined as the preset time period, so that the specific joint channel estimation time can be determined and the channel estimation efficiency is improved.

[0060] In a possible example, when the overlapping situation is that the multiple time windows overlap in time, the preset time period is a time period corresponding to each time window in the multiple overlapping time windows and in which there is no overlap.

[0061] When multiple time windows overlap, the non-overlapping time period in the time period corresponding to each time window can be determined as the preset time period. Figure 2d As shown, Figure 2d This is a schematic diagram of another joint channel estimation time provided in an embodiment of the present application. In the figure, time window 1 and time window 2 overlap. At this time, it can be determined that the first part of the time period in which time window 1 does not overlap is a preset time period, and the second part of the time period in which time window 2 does not overlap is also a preset time period. Therefore, these two preset time periods can be used for joint channel estimation.

[0062] In a specific implementation, when the preset period includes multiple time windows, it can be determined that the number of joint channel estimations in the preset period is the same as the number of time windows, that is, the period corresponding to each time window is a period of joint channel estimation.

[0063] It can be seen that in this example, the non-overlapping time period corresponding to each time window in the multiple time windows is determined as the preset time period that can be used for joint channel estimation, so that the time for joint channel estimation can be clarified and the channel estimation efficiency can be improved.

[0064] In a possible example, the time information is further used to indicate that the multiple time windows do not overlap in time.

[0065] Since the time information is information of a time window configured according to the network device, when the network device is configured, overlapping of multiple time windows may be prohibited.

[0066] It can be seen that in this example, when the time windows overlap, the joint channel estimation time can be clarified, thereby improving the channel estimation efficiency.

[0067] Step 202: The terminal sends resources according to the preset time period.

[0068] The resource is used to instruct the network device to perform joint channel estimation, and the resource may be a PUSCH or a PUCCH. The resources sent by the terminal may include multiple PUSCHs or PUCCHs, and each PUSCH or PUCCH includes a DMRS that can be used for channel estimation. In a specific implementation, each time the joint channel estimation is performed, the multiple PUSCHs or PUCCHs sent need to maintain phase continuity and / or power consistency.

[0069] In a possible example, sending resources according to the preset time period includes: obtaining the number of joint channel estimations according to the preset time period; sending resources according to preset parameters and the preset time period, and the parameter value of the preset parameter corresponding to each joint channel estimation is the same.

[0070] Among them, the preset time period includes the time of each joint channel estimation, so the number of joint channel estimations within a preset time period can be obtained. One or more joint channel estimations can be performed within a preset time period, and the terminal needs to maintain phase continuity each time the joint channel estimation is performed, that is, the parameters related to the phase need to remain unchanged. For example, two time windows are included in a preset time period, and the time period corresponding to each time window includes two PUSCHs. At this time, the preset parameters in the two PUSCHs contained in the time period corresponding to each time window are the same, but the preset parameters in the PUSCH in the first time window and the preset parameters in the PUSCH in the second time window may be different. At this time, if only one joint channel estimation is performed within the preset time period, it is necessary to keep the preset parameters in each PUSCH in the two time windows the same, that is, it is necessary to select a target parameter value at this time so that the preset parameter value in each PUSCH within the preset time period is the same. If two joint channel estimations are to be performed within the preset time period at this time, it is only necessary to keep the preset parameter value in the PUSCH within the time period corresponding to each joint channel estimation the same.

[0071] In a possible example, the preset parameters include at least one transmission parameter: modulation and coding strategy, frequency domain resource location, transmit power, transmit precoding indication, time advance command, and spatial parameter.

[0072] The frequency domain resource location may specifically include the total number of PRBs and their specific frequency domain locations. The spatial parameter may specifically refer to spatial domain beam information. The preset parameters are parameters related to the phase of the terminal, including but not limited to the parameters mentioned above.

[0073] Step 203: After receiving the resources sent from the terminal, the network device performs joint channel estimation according to the preset time period and the preset resources.

[0074] It can be seen that in this example, the terminal obtains time information from the network device, and the time information is used to determine a preset time period, and the preset time period is in a time period corresponding to multiple time windows. Then the terminal sends resources according to the preset time period, and the network device receives resources from the terminal device, and performs joint channel estimation according to the resources and the preset time period. In this way, the specific joint channel estimation time can be determined, and the channel estimation efficiency can be improved.

[0075] The embodiment of the present application provides a joint channel estimation device, which may be a terminal. Specifically, the joint channel estimation device is used to execute the steps executed by the terminal in the above joint channel estimation method. The joint channel estimation device provided in the embodiment of the present application may include modules corresponding to the corresponding steps.

[0076] The embodiment of the present application can divide the functional modules of the joint channel estimation device according to the above method example. For example, each functional module can be divided according to each function, or two or more functions can be integrated into one processing module. The above integrated module can be implemented in the form of hardware or in the form of software functional modules.
