Description

Method for determining measurement reference signal, electronic device and storage medium 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] Currently, to achieve the array gain brought by multi-antenna technology, both the transmitter and receiver must first perform beam training at the beginning of signal transmission. This beam training searches the transmitter and receiver beams to find the optimal transmit beam and end beam. However, with the advancement 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 are also becoming narrower, which means that the number of beams is gradually increasing. This leads to the use of traditional polling methods, where each reference signal corresponds to a beam for beam training. This greatly increases the number of training times and training time, resulting in increased signal transmission latency. Currently, there is an urgent need for a method to determine the parameters of the measurement reference signal so that a single measurement reference signal can correspond to multiple beams, thereby increasing the beam training speed and reducing signal transmission latency.

[0020] 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.

[0021] In the subsequent description, suffixes such as "module", "component" or "unit" used to represent elements are only used to facilitate the description of this application and have no specific meaning. Therefore, "module", "component" or "unit" can be used interchangeably.

[0022] Figure 1 is a flow chart of a method for determining a measurement reference signal provided by an embodiment of the present application. This embodiment of the present application is applicable to the case where a measurement reference signal is reported during beam training. The method can be performed by a measurement reference signal determination device, which is generally integrated into a user terminal and can be implemented through software and / or hardware methods. As shown in Figure 1, the method provided by the embodiment of the present application specifically includes the following steps:

[0023] Step 110: Receive a measurement reference signal sent by the first node.

[0024] 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.

[0025] 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 another user terminal.

[0026] 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.

[0027] Wherein, M is the total number of beam indices, N is the number of selected beam indices, and M can be an integer greater than or equal to N.

[0028] In this embodiment of the present application, a beam index corresponding to a sounding reference signal may be determined, and N beam indices may be determined for the sounding reference signal within all M beam indices. For example, a base station may have M transmit beams, i.e., M beam indices. A user terminal may receive a sounding reference signal sent by the base station via a transmit beam. After receiving the sounding reference signal, the user terminal may determine N beam indices of the transmit beam for transmitting the sounding reference signal within the M beam indices.

[0029] 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.

[0030] In an embodiment of the present application, the determined N beam indices may be represented in the form of beam type B. Different beam types B may correspond to different beam indices. Beam type B may be the number of combinations of taking N elements from M elements.

[0031] In some application embodiments, the N beam indices are determined according to at least one of the following:

[0032] signaling information received from the first node;

[0033] 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;

[0034] Preset functions.

[0035] In an embodiment of the present application, the N beam indexes can 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 radio resource control layer (RRC) control signaling, etc. In some application embodiments, the N beam indexes can also be determined by measuring the resources where the reference signal is located, and the resources can include time domain resources, frequency domain resources, and code domain resources. The N beam indexes can also be determined by a preset function, and the preset function can determine the N beam indexes by inputting parameters.

[0036] Based on the above application embodiment, the signaling information at least includes signaling information of a preset function.

[0037] In an embodiment of the present application, the signaling information for determining the N beam indices may include signaling information of a preset function for determining the N beam indices, and the signaling information may indicate that the preset function determines the N beam indices.

[0038] In some application embodiments, the input function of the preset function includes at least one of the following:

[0039] 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;

[0040] The index information of the resource of the sounding reference signal in a sounding reference signal resource set.

[0041] 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. 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.

[0042] In some other application embodiments, the input parameter set of the preset function may further include at least one of the following:

[0043] Cell identification information (cell-ID);

[0044] The burst index of the measurement reference signal set;

[0045] The port number for measuring the reference signal.

[0046] Based on the above application embodiment, the output parameters of the preset function include at least one of the following: N beam indices, beam type B.

[0047] In an embodiment of the present application, the preset function can determine the N beam indices for sending the sounding reference signal and the beam type B for sending the sounding reference signal.

[0048] In an exemplary embodiment, the N beam indices corresponding to a measurement reference signal may be determined based on the resource where the measurement reference signal resides. For example, the N beam indices corresponding to each measurement reference signal may correspond to the resource of the measurement reference signal. Assuming that the N beam indices corresponding to one measurement reference signal form an index group, the correspondence between different measurement reference signal resources and beam index groups may be as shown in Table 1. It will be understood that the resource may include at least one of a time domain resource, a frequency domain resource, and a code domain resource.

[0049] Table 1 Example of the correspondence between resources and index groups

[0050] In some application embodiments, when the measurement reference signal is sent using a packet period, the resource may also be the time index of the measurement reference signal. Referring to FIG2 , the measurement reference signal is sent with a period T, and the period index at which each measurement reference signal arrives corresponds to a beam index group, where the period index may be the period in which the measurement reference signal arrives. FIG3 shows an example diagram of a measurement reference signal sampling multiple beams for transmission.

[0051] In some other application embodiments, referring to FIG4 , the measurement reference signal may 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 contains L measurement reference signals. Within each measurement reference signal set, the measurement reference signal is sent periodically. After one measurement reference signal is sent, the next measurement reference signal set is transmitted after a period Δt. The measurement reference signal sets are also sent in a periodic manner. Referring to FIG4 , 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] In some application embodiments, when measurement reference signals are sent using a packet periodicity, the frequency domain resources and code domain resources of the measurement reference signals within 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 measurement reference signals between different reference signal sets may be different, and different measurement reference signal sets may be distinguished. Referring to 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 within the same measurement reference signal set are the same.

[0054] In 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 are distinguished by orthogonal cover code (OCC), that is, code division multiplexing; on the other hand, different measurement reference signals can also 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. For example, when 16 measurement reference signals need to be sent, Figure 6 illustrates the above situation. In Figure 6, each square represents a resource element (RE). As can be seen from Figure 6, measurement reference signals 1-4 occupy the same time-frequency resources, measurement reference signals 5-8 occupy the same time-frequency resources, measurement reference signals 9-12 occupy the same time-frequency resources, and measurement reference signals 13-16 occupy the same time-frequency resources. Code division can be used to distinguish them. For example, the orthogonal codes used by measurement reference signals 1, 2, 3, and 4 are shown in Table 3:

[0055] Table 3 Schematic diagram of measurement reference signal code division

[0056] In the embodiment of the present application, the time domain resources of measurement reference signals 1-4 and 5-8 are the same, and the measurement reference signals can be distinguished by frequency division; the frequency domain resources of measurement reference signals 1-4 and 9-12 are the same, and the measurement reference signals can be distinguished by time division; the time-frequency resources of measurement reference signals 1-4 and measurement reference signals 13-16 are different, and the measurement reference signals can be distinguished by time division-frequency division. It is understandable 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 based on the signaling of the base station, which can include MIB, SIB, DCI, MAC-CE and RRC signaling.

[0057] In other application embodiments, the N beam indices corresponding to the sounding reference signal may be determined by a preset function, which may be agreed upon by both the transmitting and receiving ends. The set of input parameters for the preset function includes at least one of the time domain resource, frequency domain resource, and code domain resource where the sounding reference signal is located. The output of the preset function may be the N beam indices or other representations of the N beam indices, which may include but are not limited to a bitmap, beam type B, and the like.

[0058] Based on the above application embodiment, the preset function includes the following forms:

[0059] Wherein, k is the resource index of the measurement reference signal, and the resource includes at least one of the time domain resource, the frequency domain resource, and the code domain resource, and L is such that 2 L ≤M, where M is the total number of beam indices, and index(i) is the i-th beam index among the N beam indices.

[0060] In other application embodiments, when the output of the preset function is beam type B, the beam type of the sounding reference signal with resource index k can be determined using the following formula:

[0061] Where L is such that The maximum integer.

[0062] In other application embodiments, the N beam indices corresponding to the measurement reference signals with time domain resource indexes j and frequency domain resource indexes k respectively can be determined using the following formula:

[0063] Further, when the input set of the preset function is at least one of the cell identity information (cell-ID), the burst index of the measurement reference signal set, and the port number of the measurement reference signal, for example, I1 represents the cell identity information, I2 represents the measurement reference signal set index, and I3 represents the port number of the measurement reference signal, the preset function may also be one of the following forms:

[0064] It can be understood that the parameters in equations (4), (5) and (6) have the same meanings as the parameters in equation (1).

[0065] In other application embodiments, the preset function may also be implemented in the form of a hash function, which may map the input parameters to beam type B, where As shown in FIG7 , each input parameter group can find a corresponding beam type, and multiple input parameter groups may correspond to one beam type.

[0066] 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 terminal 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.

[0067] The method for determining a sounding reference signal provided in an embodiment of the present application further includes: determining a receiving parameter corresponding to each of the N beam indexes.

[0068] 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).

[0069] 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 measurement reference signal includes the N beam indexes at the predetermined time domain position.

[0070] 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 measurement reference signal may be a measurement reference signal containing the above-mentioned N beam indexes at a predetermined time domain position.

[0071] In some application embodiments, the measurement reference signal exists in at least two different predetermined time domain positions, and the N beam indices corresponding to the measurement reference signal at the at least two different predetermined time domain positions are different.

[0072] In the embodiment of the present application, the N beam indices corresponding to different predetermined time domain positions of the measurement reference signal are different.

[0073] In some application embodiments, the reception parameter of the beam index is the sum of reception parameters of the sounding reference signal including the beam index at a preset number of time domain positions.

[0074] 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 including 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.

[0075] In some application embodiments, a beam index set corresponding to each of the preset number of time domain positions of the sounding reference signal includes at least one beam index corresponding to the sounding reference signal.

[0076] In the embodiment of the present application, the measurement reference signal corresponds to a beam index set at each time domain position, and the beam index set contains at least one beam index included in the measurement reference signal.

[0077] 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.

[0078] In some other application embodiments, when the user terminal receives K measurement reference signals, each measurement reference signal corresponds to N beam indices, and at least two measurement reference signals correspond to different N beam indices. After receiving K measurement reference signals, the user terminal can obtain reception parameters P1, P2, ..., P corresponding to each measurement reference signal. K The user can calculate the reception parameters corresponding to each beam index based on the reception parameters corresponding to each measurement reference signal. The reception parameters for each beam index are the sum of the reception parameters for the measurement reference signals containing that beam index. Table 4 below illustrates how the reception parameters corresponding to each beam index are determined. Table 4 assumes that the user receives four measurement reference signals, each corresponding to two beam indices.

[0079] Table 4. Example table for determining beam index reception parameters

[0080] In Table 4, the user end receives four sounding reference signals corresponding to beams 1 and 3, beams 2 and 4, beams 3 and 4, and beams 1 and 2. The reception parameters of these four sounding reference signals are P1, P2, P3, and P4, respectively. The reception parameter for each beam index is the sum of the reception parameters of the sounding reference signals containing that beam index. Therefore, the reception parameters for the four beam indices are the sum of the values ​​in each column in the table. The reception parameters for beam indices 1, 2, 3, and 4 are P1+P4, P2+P4, P1+P3, and P2+P3, respectively.

[0081] In some application embodiments, the method further includes: selecting K beam indexes from the M beam indexes, and reporting the K beam indexes.

[0082] In an embodiment of the present application, K beam indexes may be selected from all 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 beam indexes.

[0083] Furthermore, based on the above-mentioned application embodiment, the receiving parameters corresponding to each beam index in the K beam indexes are reported.

[0084] Specifically, when K beam indexes are selected for reporting, the reception parameters of the K beam indexes may also be reported together.

[0085] 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.

[0086] Specifically, after receiving the measurement reference signal, the measurement reference signal set to which the measurement reference signal is located 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.

[0087] Furthermore, based on the above-mentioned 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.

[0088] In the embodiment of the present application, the measurement reference signal set may have the same frequency domain resources and code domain resources, and all measurement reference signals in the same measurement reference signal set may have the same frequency domain resources and code domain resources.

[0089] 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.

[0090] In an embodiment of the present application, each measurement reference signal can correspond to one or more beam indices respectively, and one or more beam indices corresponding to the same measurement reference signal can form a beam index set, and each beam index in each beam index set can correspond to at least one of the transmitted measurement reference signals.

[0091] Based on the above application embodiment, the sounding reference signal set includes at least two sounding reference signals corresponding to different beam index sets.

[0092] In an embodiment of the present application, the measurement reference signal set may include at least two measurement reference signals, each of which corresponds to a beam index set, and the beam index sets corresponding to the at least two measurement reference signals are different.

[0093] In some application embodiments, the provided method for determining a sounding reference signal further includes: determining a receiving parameter corresponding to each beam index in a beam index set.

[0094] In an embodiment of the present application, one or more beam indices 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.

[0095] In some application embodiments, the reception parameters corresponding to each beam index include reception parameters of a sounding reference signal corresponding to the beam index.

[0096] 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 of the transmitted measurement reference signal.

[0097] 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.

[0098] In an embodiment of the present application, the receiving parameters corresponding to each beam index in the beam index set can 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 can 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.

[0099] Furthermore, based on the above application embodiment, it also includes selecting X beam indexes from the beam indexes and reporting the X beam indexes.

[0100] In the embodiment of the present application, X beam indexes may be determined from the beam indexes corresponding to the measurement reference signals, and the determined X beam indexes may be reported.

[0101] In some application embodiments, the method further includes: reporting reception parameters of the X beam indexes.

[0102] Specifically, the determined reception parameters of the X beam indexes may also be reported. The method for determining the reception parameters of the X beam indexes may be determined as described in any of the foregoing implementations.

[0103] 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. Alternatively, the user may report X1 beam indexes with the largest reception parameters and X2 beam indexes with the smallest reception parameters to the base station.

[0104] In other exemplary implementations, the user terminal may also report the beam index and reception parameters of the beam index.

[0105] 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.

[0106] 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.

[0107] Based on the above application embodiment, the N value and / or N beam indices are determined according to signaling from the first node.

[0108] 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.

[0109] Based on the above application embodiment, N beam indices correspond to N reference signals that are quasi-co-located with the measurement reference signal.

[0110] Specifically, each beam index corresponds to a reference signal. For example, one measurement reference signal corresponds to N beam indices and has the following characteristics: one measurement reference signal has a quasi co-location (QCL) relationship with the N reference signals, that is, each beam index corresponds to a reference signal.

[0111] In other application embodiments, the quasi-co-location type of the measurement reference signals that have a quasi-co-location relationship among N measurement reference signals is the same. Specifically, the quasi-co-location relationship between a measurement reference signal and N reference signals may be of different types. 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 the 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 the 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 the N measurement reference signals; if the QCL relationship is QCL-TypeD, it means that the spatial reception parameters of a measurement reference signal and the 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 the N measurement reference signals.

[0112] Further, based on the above-mentioned application embodiment, the receiving parameter includes at least one of the following: measurement of reference signal received power, measurement of reference signal received strength, and measurement of reference signal received quality.
