Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to a method for determining a measurement reference signal, an electronic device, and a storage medium. Background Art

[0002] At present, in order to obtain the array gain brought by multi-antenna technology, at the beginning of signal transmission, both the transmitter and receiver need to perform beam training first. Through beam training, the beams of the transmitter and receiver are searched to find the best transmission beam and the end beam. However, with the development of wireless communication technology, the number of antennas has gradually increased, and the transmission frequency band has gradually increased. The beams emitted by the antenna array have become narrower and narrower, which means that the number of beams has gradually increased, resulting in the use of traditional polling methods. Each reference signal corresponds to a beam for beam training. The number of training times and training time are greatly increased, resulting in an increase in signal transmission delay. At present, there is an urgent need for a method for determining the parameters of a measurement reference signal, so that one measurement reference signal can correspond to multiple beams, thereby increasing the beam training speed and reducing the signal transmission delay.

[0019] It should be understood that the specific implementations described herein are only used to explain the present application and are not used to limit the present application.

[0020] In the subsequent description, suffixes such as "module", "component" or "unit" used to represent elements are only used to facilitate the description of the present application and have no specific meaning themselves. Therefore, "module", "component" or "unit" may be used interchangeably.

[0021] Figure 1This is a flow chart of a method for determining a measurement reference signal provided by an embodiment of the present application. The embodiment of the present application is applicable to the case where a measurement reference signal is reported during beam training. The method can be executed by a device for determining a measurement reference signal, which is generally integrated in a user terminal and can be implemented by software and / or hardware methods. Figure 1 As shown, the method provided in the embodiment of the present application specifically includes the following steps:

[0022] Step 110: Receive a measurement reference signal sent by the first node.

[0023] The first node may be a node that sends a measurement reference signal, and the first node may include a base station or other user terminal. The measurement reference signal may be a known signal provided by a transmitting end to a receiving end for channel estimation or channel detection.

[0024] In an embodiment of the present application, a user terminal may receive a measurement reference signal sent by a first node such as a base station or other user terminals.

[0025] Step 120: Determine N beam indices corresponding to the measurement reference signal within the M beam indices, where N is an integer greater than or equal to 1, and M is the total number of beam indices, and M is an integer greater than or equal to 1.

[0026] Wherein, M is the total number of beam indexes, N is the number of selected beam indexes, and M may be an integer greater than or equal to N.

[0027] In an embodiment of the present application, a beam index corresponding to a measurement reference signal may be determined, and N beam indexes may be determined for the measurement reference signal within all M beam indexes. Exemplarily, a base station has a total of M transmit beams, that is, a total of M beam indexes, and a user terminal may receive a measurement reference signal sent by a base station through a transmit beam. After receiving the measurement reference signal, the user terminal may determine N beam indexes of the transmit beam for sending the measurement reference signal within the M beam indexes.

[0028] In some application embodiments, the N beam indices are represented by beam type B. Where M is the total number of beam indices, It represents the number of combinations of N elements selected from M elements.

[0029] In an embodiment of the present application, the determined N beam indexes may be represented in the form of beam type B, different beam types B may correspond to different beam indexes, and beam type B may be the number of combinations of taking N elements from M elements.

[0030] In some application embodiments, the N beam indices are determined according to at least one of the following:

[0031] signaling information received from the first node;

[0032] The resource where the measurement reference signal is located includes at least one of the following: time domain resource, frequency domain resource, and code domain resource;

[0033] Preset functions.

[0034] In an embodiment of the present application, the N beam indexes may be determined by signaling information of the first node, and the signaling information may include a master information block (MIB), a system information block (SIB), downlink control information (DCI), a media access control layer control element (MAC-CE), a control signaling of a radio resource control layer (RRC), etc. In some application embodiments, the N beam indexes may also be determined by measuring the resources where the reference signal is located, and the resources may include time domain resources, frequency domain resources, and code domain resources. The N beam indexes may also be determined by a preset function, and the preset function may determine the N beam indexes by inputting parameters.

[0035] Based on the above application embodiment, the signaling information at least includes signaling information of a preset function.

[0036] In an embodiment of the present application, the signaling information for determining the N beam indexes may include signaling information of a preset function for determining the N beam indexes, and the signaling information may indicate that the preset function determines the N beam indexes.

[0037] In some application embodiments, the input function of the preset function includes at least one of the following:

[0038] The resource where the measurement reference signal is located includes at least one of the following: time domain resources, frequency domain resources, and code domain resources;

[0039] The index information of the resource of the sounding reference signal in a sounding reference signal resource set.

[0040] In an embodiment of the present application, the preset function can determine the corresponding N beam indices through the resources where the input measurement reference signal is located, and the resources may include one or more of time domain resources, frequency domain resources, and code domain resources. Alternatively, the preset function can also determine the corresponding N beam indices through the index information of the measurement reference signal resources in the corresponding measurement reference signal resource set.

[0041] In some other application embodiments, the input parameter set of the preset function may also include at least one of the following:

[0042] Cell identification information (cell-ID);

[0043] The burst index of the measurement reference signal set;

[0044] The port number of the reference signal measurement.

[0045] Based on the above application embodiment, the output parameters of the preset function include at least one of the following: N beam indexes and beam type B.

[0046] In an embodiment of the present application, the preset function can determine the N beam indices for sending the measurement reference signal and the beam type B for sending the measurement reference signal.

[0047] In an exemplary implementation, the N beam indexes corresponding to the measurement reference signal may be determined according to the resource where the measurement reference signal is located. For example, the N beam indexes corresponding to each measurement reference signal may correspond to the resource of the measurement reference signal. Assuming that the N beam indexes corresponding to a measurement reference signal are an index group, the correspondence between different measurement reference signal resources and beam index groups may be as shown in Table 1. It can be understood that the resource may include at least one of a time domain resource, a frequency domain resource, and a code domain resource.

[0048] Table 1 Example of the correspondence between resources and index groups

[0049] Measurement reference signal 1 Measurement reference signal 2 Measurement reference signal 3 ... Resource 1 Resource 2 Resource 3 ... Index Group 1 Index Group 2 Index Group 3 ...

[0050] In some application embodiments, when the measurement reference signal is sent using a packet period, the resource may also be a time index of the measurement reference signal, see Figure 2 , the measurement reference signal is sent with a period T, and each period index at which the measurement reference signal arrives corresponds to a beam index group, where the period index can be the period in which the measurement reference signal arrives. Figure 3 An example diagram of measuring reference signal sampling for multiple beam transmissions is given.

[0051] In other application examples, see Figure 4The measurement reference signal can also be sent in a group periodic manner. The measurement reference signal is divided into multiple measurement reference signal sets. Each measurement reference signal set has L measurement reference signals. In each measurement reference signal set, the measurement reference signal is sent periodically. After a measurement reference signal is sent, the next measurement reference signal set is sent after a period of time Δt. The measurement reference signal set is also sent in a periodic manner. See Figure 4 When the measurement reference signal is sent in a group periodic manner, each measurement reference signal may correspond to a beam index group. Exemplarily, the correspondence between each measurement reference signal and the beam index group is shown in Table 2;

[0052] Table 2 Example of the correspondence between measurement reference signals, resources and index groups

[0053]

[0054] In some application embodiments, when the measurement reference signal is sent in a packet period, the frequency domain resources and code domain resources of the measurement reference signal in a measurement reference signal set may be the same, and different measurement reference signals may be distinguished by time resources. In other application embodiments, the frequency domain resources and code domain resources of the measurement reference signals between different reference signal sets may be different, and different measurement reference signal sets may be distinguished. Figure 5 , measurement reference signal set 1 and measurement reference signal 2 may occupy different frequency domain resources, but the frequency domain resources of all reference signals in the same measurement reference signal set are the same.

[0055] In some other application embodiments, the transmission method of the measurement reference signal can be flexibly configured, and time domain, frequency domain, code domain resources, etc. can be used to distinguish different measurement reference signals. On the one hand, different measurement reference signals can use the same time-frequency resources, but they can be distinguished by orthogonal cover code (OCC), that is, code division multiplexing; on the other hand, different measurement reference signals can be distinguished by different time-frequency resources; and the two can also be combined to use time, frequency, and code resources to jointly distinguish measurement reference signals. Exemplarily, when 16 measurement reference signals need to be sent, Figure 6 The above situation is explained. Figure 6 In the example, each square represents a resource element (RE). Figure 6 It can be seen that the time-frequency resources occupied by measurement reference signals 1-4, 5-8, 9-12, and 13-16 are the same, and can be distinguished by code division. For example, the orthogonal codes used by measurement reference signals 1, 2, 3, and 4 are shown in Table 3:

[0056] Table 3 Schematic diagram of measurement reference signal code division

[0057] Measurement reference signal number Orthogonal Code 1 [+1,+1,+1,+1] 2 [+1,-1,+1,-1] 3 [+1,+1,-1,-1] 4 [-1,+1,+1,-1]

[0058] In the embodiment of the present application, the frequency domain resources where measurement reference signals 1-4 and 5-8 are located are the same, and the measurement reference signals can be distinguished by time division; the frequency domain resources where measurement reference signals 1-4 and 12-16 are located are the same, and the measurement reference signals can be distinguished by time division; the time-frequency resources where measurement reference signals 1-4 and measurement reference signals 9-12 are located are different, and the measurement reference signals can be distinguished by time division-frequency division. It can be understood that the time-frequency code resources of the above-mentioned measurement reference signals can be flexibly configured by the base station, and the user can obtain the resource information of the above-mentioned measurement reference signals according to the signaling of the base station, which can include MIB, SIB, DCI, MAC-CE and RRC signaling.

[0059] In some other application embodiments, the N beam indexes corresponding to the measurement reference signal may be determined by a preset function, which may be agreed upon by both the transmitting and receiving ends. The input parameter set of the preset function includes at least one of the time domain resources, frequency domain resources, and code domain resources where the measurement reference signal is located, and the output of the preset function may be N beam indexes or other representations of the N beam indexes, which may include but are not limited to bitmaps, beam type B, etc.

[0060] Based on the above application embodiment, the preset function includes the following forms:

[0061]

[0062] Wherein, k is a resource index of a measurement reference signal, the resource includes at least one of a time domain resource, a frequency domain resource, and a code domain resource, and L is a value such that 2 L ≤M, M is the total number of beam indices, and index(i) is the i-th beam index among the N beam indices.

[0063] In other application embodiments, when the output of the preset function is beam type B, the measurement parameter with resource index k is

[0064] The beam type of the reference signal can be determined by the following formula:

[0065]

[0066] Among them, L is such that The maximum integer.

[0067] In some other application embodiments, the time domain resource index and the frequency domain resource index are respectively the measurement reference signal j and k.

[0068] The corresponding N beam indices can be determined using the following formula:

[0069]

[0070] Further, when the input set of the preset function is at least one of the cell identity information (cell-ID), the index of the measurement reference signal set burst index, and the port number of the measurement reference signal port, for example, using I 1 Indicates the cell identification information, I 2 Indicates the measurement reference signal set index, I 3 Indicates the port number of the measurement reference signal. The preset function can also be one of the following forms:

[0071]

[0072]

[0073]

[0074] It can be understood that the parameters in equations (4), (5) and (6) have the same meaning as the parameters in equation (1).

[0075] In some other application embodiments, the preset function may also be implemented in the form of a hash function, which may map the input parameter to a beam type B, where like Figure 7 As shown, each input parameter group can find a corresponding beam type, and multiple input parameter groups may correspond to one beam type.

[0076] In other application embodiments, the input parameters of the preset function can also be determined by signaling sent by the base station, which may include one or more of MIB signaling, SIB signaling, DCI signaling, MAC-CE signaling and RRC signaling. For example, the base station and the user end can pre-agree on multiple preset functions, and the user determines which form of the preset function and input parameters to use based on the signaling of the base station.

[0077] The method for determining a measurement reference signal provided in an embodiment of the present application further includes: determining a receiving parameter corresponding to each beam index among the N beam indexes.

[0078] In an embodiment of the present application, after receiving the measurement reference signal, the receiving parameters of the measurement reference signal can also be determined, and the receiving parameters of each beam index in the N beam indexes can be determined based on the receiving parameters. The receiving parameters may include at least one of the following: measurement reference signal receiving power (Reference Signal Receiving Power, RSRP), measurement reference signal receiving strength (Received Signal Strength Indicator, RSSI), and measurement reference signal receiving quality (Reference Signal Receiving Quality).

[0079] In some application embodiments, the reception parameters corresponding to each beam index in the N beam indexes include reception parameters of a measurement reference signal at a predetermined time domain position, and the one measurement reference signal includes the N beam indexes at the predetermined time domain position.

[0080] In an embodiment of the present application, the receiving parameters corresponding to each of the N beam indexes may be the receiving parameters of a measurement reference signal at a predetermined time domain position, and the one measurement reference signal may be a measurement reference signal containing the above-mentioned N beam indexes at a predetermined time domain position.

[0081] In some application embodiments, the measurement reference signal exists in at least two different predetermined time domain positions, and the N beam indexes corresponding to the measurement reference signal at the at least two different predetermined time domain positions are different.

[0082] In the embodiment of the present application, the N beam indexes corresponding to the measurement reference signal at different predetermined time domain positions are different.

[0083] In some application embodiments, the reception parameter of the beam index is the sum of the reception parameters of the measurement reference signal including the beam index at a preset number of time domain positions.

[0084] In an embodiment of the present application, the receiving parameter of a beam index may be the sum of the receiving parameters of the measurement reference signal of the beam index at a preset number of time domain positions, and the preset number may be a preconfigured number that can be preconfigured and determined.

[0085] In some application embodiments, a beam index set corresponding to each of the time domain positions of the measurement reference signal in the preset number of time domain positions includes at least one beam index corresponding to the measurement reference signal.

[0086] In the embodiment of the present application, the measurement reference signal corresponds to a beam index set at each time domain position, and there is at least one beam index included in the measurement reference signal in the beam index set.

[0087] In an exemplary embodiment, when the user terminal receives the measurement reference signal only once, the receiving power of the received measurement reference signal is P, and the receiving parameter of each beam index in the N beam indexes corresponding to the measurement reference signal is recorded as P.

[0088] In some other application embodiments, when the user terminal receives K measurement reference signals, each measurement reference signal corresponds to N beam indexes, and at least two measurement reference signals correspond to different N beam indexes. After receiving K measurement reference signals, the user terminal can obtain the receiving parameter P corresponding to each measurement reference signal. 1 ,P 2 ,...,P K , the user can calculate the receiving parameters corresponding to each beam index according to the receiving parameters corresponding to each measurement reference signal, where the receiving parameters of each beam index are the sum of the receiving parameters of the measurement reference signals containing the beam index. Referring to Table 4 below, the method for determining the receiving parameters corresponding to each beam index can be explained. In Table 4, it is assumed that the user receives four measurement reference signals in total, and each measurement reference signal corresponds to two beam indexes.

[0089] Table 4. Example table for determining beam index receiving parameters

[0090]

[0091] In Table 4, the user end receives four measurement reference signals corresponding to beams 1, 3, beams 2, 4, beams 3, 4, and beams 1, 2. The receiving parameters of the four measurement reference signals are P 1 , P 2 , P 3 , P 4 The receiving parameters of each beam index are the sum of the receiving parameters of the measurement reference signal containing this beam index. Therefore, the receiving parameters of the four beam indices are the sum of each column in the table. The receiving parameters of beam indices 1, 2, 3, and 4 are P, 1 +P 4 , P 2 +P 4 , P 1 +P 3 , P 2 +P 3 .

[0092] In some application embodiments, the method further includes: selecting K beam indexes from the M beam indexes, and reporting the K beam indexes.

[0093] In the embodiment of the present application, K beam indexes may be selected from all the M beam indexes, and the selected K beam indexes may be reported. It may be understood that the selected K beam indexes may be part of all the beam indexes.

[0094] Further, based on the above-mentioned application embodiment, the receiving parameters corresponding to each beam index in the K beam indexes are reported.

[0095] Specifically, when K beam indexes are selected for reporting, the receiving parameters of the K beam indexes may also be reported together.

[0096] In some application embodiments, the further step includes determining a measurement reference signal set in which the measurement reference signal is located and determining at least one beam index corresponding to each measurement reference signal in the measurement reference signal set.

[0097] Specifically, after receiving the measurement reference signal, the measurement reference signal set to which the measurement reference signal belongs can be determined, and the corresponding beam index of each measurement reference signal in the measurement reference signal set can be determined. Each measurement reference signal in the measurement reference signal set can correspond to one or more beam indexes.

[0098] Further, based on the above application embodiment, the frequency domain resources and code domain resources of all the measurement reference signals in the measurement reference signal set are the same.

[0099] In an embodiment of the present application, the measurement reference signal set may have the same frequency domain resources and code domain resources, and the frequency domain resources and code domain resources of all measurement reference signals in the same measurement reference signal set may be the same.

[0100] In some application embodiments, at least one beam index corresponding to each measurement reference signal constitutes a beam index set, and each beam index in the beam index set corresponds to at least one measurement reference signal in the measurement reference signal.

[0101] In an embodiment of the present application, each measurement reference signal may correspond to one or more beam indices respectively, and one or more beam indices corresponding to the same measurement reference signal may form a beam index set, and each beam index in each beam index set may correspond to at least one of the transmitted measurement reference signals.

[0102] Based on the above application embodiment, the measurement reference signal set includes at least two measurement reference signals corresponding to different beam index sets.

[0103] In an embodiment of the present application, there may be at least two measurement reference signals in the measurement reference signal set, and the at least two measurement reference signals respectively correspond to a beam index set, and the beam index sets corresponding to the at least two measurement reference signals are different.

[0104] In some application embodiments, the provided method for determining a measurement reference signal further includes: determining a receiving parameter corresponding to each beam index in a beam index set.

[0105] In an embodiment of the present application, one or more beam indexes included in each received measurement reference signal constitute a beam index set. When reporting, the receiving parameter corresponding to each beam index in the beam index set corresponding to the measurement reference signal can also be determined.

[0106] In some application embodiments, the reception parameters corresponding to each beam index include reception parameters of a measurement reference signal corresponding to the beam index.

[0107] In an embodiment of the present application, the reception parameters of each beam index in the beam index set may include the reception parameters of the measurement reference signal corresponding to the beam index, and the beam index corresponding to the measurement reference signal may include the beam index for transmitting the measurement reference signal.

[0108] In some other application embodiments, the reception parameter corresponding to the beam index in the beam index set includes the sum of the reception parameters of all measurement reference signals corresponding to the beam index.

[0109] In an embodiment of the present application, the receiving parameters corresponding to each beam index in the beam index set may be the sum of the receiving parameters of all measurement reference signals corresponding to the beam index. For example, all measurement reference signals corresponding to beam index a may be all measurement reference signals sent using beam index a, and beam index a is at least one of the beam indices used to send each measurement reference signal.

[0110] Further, based on the above application embodiment, it also includes selecting X beam indexes from the beam indexes and reporting the X beam indexes.

[0111] In the embodiment of the present application, X beam indexes may be determined from the beam indexes corresponding to each measurement reference signal, and the determined X beam indexes may be reported.

[0112] In some application embodiments, the method further includes: reporting reception parameters of the X beam indexes.

[0113] Specifically, the determined reception parameters of the X beam indexes may also be reported, and the method for determining the reception parameters of the X beam indexes may be determined as described in any of the foregoing implementations.

[0114] In some exemplary embodiments, after receiving the measurement reference signal and determining the reception parameters of each beam index, the user terminal may report X beam indexes to the base station, where X is an integer not less than 1. For example, the user may report X beam indexes with the largest reception parameters to the base station, or the user may report X1 beam indexes with the largest reception parameters to the base station, and report X2 beam indexes with the smallest reception parameters.

[0115] In other exemplary implementations, the user terminal may also report a beam index and a receiving parameter of the beam index.

[0116] Furthermore, the above-mentioned reporting may include periodic reporting. For example, the user may report once after receiving K measurement reference signals, where K is a positive integer; or may report once after receiving a measurement reference signal set.

[0117] It can be understood that the above-mentioned reporting can also include non-periodic reporting, for example, reporting once after receiving the signaling from the base station, or reporting according to the non-periodic reporting method configured by the base station, or triggering reporting after certain conditions are met, such as reporting the beam index and receiving parameters when the maximum receiving parameter of the beam index is greater than the threshold μ.

[0118] Based on the above application embodiment, the N value and / or N beam indexes are determined according to the signaling of the first node.

[0119] In an embodiment of the present application, the first node may determine the number N of beam indices determined by the measurement reference signal through signaling, or the first node may determine N beam indices corresponding to the measurement reference signal through signaling.

[0120] Based on the above application embodiment, N beam indexes correspond to N reference signals that are quasi-co-located with the measurement reference signal.

[0121] Specifically, each beam index has a corresponding relationship with a reference signal. For example, a measurement reference signal corresponds to N beam indices and has the following characteristics: a measurement reference signal has a quasi co-location (QCL) relationship with the N reference signals, that is, each beam index has a corresponding relationship with a reference signal.

[0122] In some other application embodiments, the N sounding reference signals that have a quasi-co-location relationship have the same quasi-co-location type.

[0123] Specifically, there may be different types of quasi-co-location relationships between a measurement reference signal and N reference signals. Exemplarily, if the QCL relationship is QCL-TypeA, it means that the Doppler shift, Doppler spread, average delay, and delay spread of a measurement reference signal are the same or similar to those of N measurement reference signals; if the QCL relationship is QCL-TypeB, it means that the Doppler shift and Doppler spread of a measurement reference signal are the same or similar to those of N measurement reference signals; if the QCL relationship is QCL-TypeC, it means that the Doppler shift and average delay of a measurement reference signal are the same or similar to those of N measurement reference signals; if the QCL relationship is QCL-TypeA, it means that the spatial reception parameters of a measurement reference signal and N measurement reference signals are the same or similar, that is, the receiving or transmitting beam of a measurement reference signal is similar to the beams of N measurement reference signals.

[0124] Further, based on the above application embodiment, the receiving parameter includes at least one of the following: measuring the received power of a reference signal, measuring the received strength of a reference signal, and measuring the received quality of a reference signal.

[0128] In an embodiment of the present application, a measurement reference signal sent by a first node is received through a signal receiving module, and a measurement result module determines N beam indexes within M beam indexes according to the measurement reference signal, so that one measurement reference signal corresponds to multiple beams, providing beam training speed, thereby reducing signal transmission delay.
