Description

Measurement result processing method, communication node, storage medium and program product TECHNICAL FIELD

[0001] The present application relates to the technical field of wireless communication, for example, to a measurement result processing method, a communication node, a storage medium and a program product. BACKGROUND

[0002] In the process of downlink beam training, a user measures a downlink reference signal and processes and reports the measurement result. The conventional measurement and reporting scheme is that the user measures the received power of each reference signal and reports the indices of the k reference signals with the strongest received power and the quantized received power thereof, to help the base station perform beam calibration and training. However, when the transmit beam is narrowed, the above measurement and reporting scheme requires transmitting more downlink reference signals, which results in large downlink training pilot overhead and is not conducive to fast beam alignment. On the other hand, although the base station can also perform additional processing on the measurement result reported by the user to obtain processing gain and reduce the number of training times, the result reported by the user is quantized, and the quantization error will affect the processing accuracy. In order to reduce the pilot overhead, the base station can transmit a small number of reference signals with a wide beam, and the user performs additional processing on the measurement result locally before reporting, which can avoid the influence of the quantization error of the reported result on the additional processing, and also obtain processing gain. However, in the related art, the transmission mode of the reference signal is transparent to the user, and the user cannot obtain the transmission beam information of the reference signal, so it is difficult for the communication node under the existing framework to perform additional processing on the measurement result.

It should be explained that the embodiments in the present application and the features in the embodiments can be combined with each other as long as there is no conflict.

[0023] FIG. 1 is a flow chart of a measurement result processing method according to an embodiment. As shown in FIG. 1, the measurement result processing method according to the embodiment of the present application is applied to a first communication node, and the method comprises the following steps:

[0024] S110, sending processing mode indication information of the measurement result of the reference signal, the processing mode indication information being used for indicating the processing mode of the measurement result of the reference signal by the second communication node.

[0025] The processing mode indication information can be understood as information indicating the processing mode of data, and is used for indicating the processing mode of the measurement result of the reference signal by the second communication node.

[0026] In the reference signal measurement process, the first communication node determines the processing mode of the measurement result of the reference signal. The processing mode can be pre-set in multiple modes. When determining the processing mode, the first communication node can select a suitable processing mode according to the type of the reference signal, the number of the reference signals, the transmission beam of the reference signal and other information. After determining the processing mode, the processing mode indication information is generated according to the processing mode, the processing mode is indicated by the processing mode indication information, and the processing mode indication information is sent to the second communication node, so that the second communication node determines the processing mode of the measurement result after receiving the processing mode indication information and processes the measurement result according to the received processing mode.

[0028] In some embodiments, the reference signal can be a channel state information-reference signal (CSI-RS), a synchronization signal / physical broadcast channel block (SSB), a demodulation reference signal (DMRS), a cell reference signal (CRS), or the like.

[0029] In some embodiments, the first communication node is a base station.

[0030] In some embodiments, the second communication node is a user equipment.

[0031] In some embodiments, the processing mode indication information indicates the processing mode through at least one of the following: explicit indication, which is used to directly indicate the processing mode; or implicit indication, which is used to indicate the processing mode through inference or mapping.

[0032] The processing mode indication information can indicate the processing mode through explicit indication, implicit indication, or a combination of explicit indication and implicit indication. Explicit indication is used to directly indicate the processing mode, for example, directly carrying the processing mode in the transmitted information; implicit indication is used to indicate the processing mode through inference or mapping, that is, not directly indicating the processing mode, but determining the processing mode through inference or mapping, for example, carrying related information of the processing mode in the transmitted information, and finally obtaining the processing mode by processing the transmitted information.

[0033] In some embodiments, the explicit indication includes indicating the processing mode through downlink signaling.

[0034] The first communication node can indicate the processing mode by sending downlink signaling to the second communication node, for example, the first communication node sends downlink signaling to the second communication node, and the processing mode indication information is carried in the downlink signaling, and the corresponding processing mode can be determined through the processing mode indication information. In this case, the first communication node can directly inform the second communication node of the processing mode of the measurement result through the downlink signaling.

[0035] In some embodiments, the downlink signaling includes at least one of: a downlink broadcast message; or control signaling.

[0036] The downlink signaling can be a downlink broadcast message, for example, information carried on a physical broadcast channel block; the downlink signaling can also be control signaling, which can be signaling including downlink control information (Downlink Control Information), medium access control-control element (Medium Access Control-Control Element, MAC-CE) and radio resource control layer (Radio Resource Control).

[0037] In some embodiments, the implicit indication includes at least one of: indicating the processing mode through a reference signal; or indicating the processing mode through a reference signal set.

[0038] The first communication node implicitly indicates the processing mode to the second communication node through at least one of a reference signal or a reference signal set. The processing mode is indicated through a reference signal, for example, the processing mode is implicitly indicated in the reference signal. The reference signal set can be understood as a resource set in which the reference signal is located, for example, the processing mode is associated with the reference signal set in advance, the reference signal set to which the reference signal belongs is determined, and the processing mode is implicitly indicated through the reference signal set.

[0039] In some embodiments, the processing mode is a processing matrix, and the processing matrix includes at least one element.

[0040] The processing matrix can be understood as a matrix representing the processing mode, and the processing mode can be represented by a matrix. The size of the processing matrix can be pre-set or determined according to the number of reference signals to be processed, etc. The number of elements in the processing matrix depends on the size of the processing matrix, and the element Cij in the processing matrix is the value of the i-th row and j-th column in the matrix. If the processing mode is linear, the processing mode can be represented by a matrix, and the first communication node can directly inform the second communication node of the processing matrix C through the downlink signaling, or inform the second communication node of the processing matrix C through a reference signal, a reference signal set, etc.

[0041] In some embodiments, the sending the processing mode indication information comprises at least one of the following: sending all elements in the processing matrix; or quantizing elements in the processing matrix and sending all elements in the quantized processing matrix.

[0042] The first communication node can send all elements in the processing matrix directly, or can quantize the processing matrix and then send, or can send in combination of the above two manners; or can quantize elements in the processing matrix to obtain a quantized processing matrix, and send all elements in the quantized processing matrix. When quantizing the processing matrix, each element can be quantized, or only part of the elements can be quantized. The first communication node can determine whether to quantize elements in the processing matrix by analyzing the elements in the processing matrix, for example, when the elements in the processing matrix are not integers, the elements in the matrix are quantized. When the first communication node sends the processing mode indication information by sending all elements in the processing matrix, the elements in the processing matrix can be used as the processing mode indication information to indicate the processing mode.

[0043] In some embodiments, the sending the processing mode indication information comprises: sending a sequence number of the processing matrix.

[0044] The first communication node and the second communication node pre-store at least one processing matrix and label the processing matrix, each processing matrix corresponds to a sequence number, and a processing matrix can be uniquely determined by the sequence number. When the first communication node sends the processing mode indication information, the first communication node can directly send the sequence number of the processing matrix, and indicate the second communication node to use which processing matrix to process the measurement result by the sequence number of the processing matrix.

[0045] In some embodiments, the sending the processing mode indication information comprises: sending a sequence number of at least one vector, each vector being used to determine the processing matrix.

[0046] Since the matrix can be composed of vectors, the matrix can be determined by the vectors. The first communication node and the second communication node pre-store at least one vector, and label the vectors, each vector corresponding to a serial number, and a vector can be uniquely determined by the serial number. When the first communication node sends the processing mode indication information, it can directly send the serial number of the vector, and indicate the second communication node to use which vectors to generate the processing matrix, and then process the measurement result by the processing matrix. The vector can be a row vector or a column vector. When generating the processing matrix according to the vectors, the vectors can be directly sorted in a certain order to form the processing matrix, or the vectors can be weighted, and then the weighted vectors are sorted in a certain order to form the processing matrix. The weighting coefficient can be pre-determined, or indicated by the first communication node, for example, sent together with the serial number of the vector, etc.

[0047] In some embodiments, the sending the processing mode indication information comprises: sending at least one root sequence, each root sequence being used to determine the processing matrix.

[0048] The first communication node can indicate the processing matrix by sending the root sequence, and the root sequence can be carried in the reference signal; the first communication node sends at least one root sequence to the second communication node, and the root sequence can form the processing matrix.

[0049] In some embodiments, the sending the processing mode indication information comprises: sending serial numbers of at least one vector, each serial number of the vector being carried by a root sequence, and each vector being used to determine the processing matrix.

[0050] The serial numbers of the at least one vector are carried by the root sequence, and the serial numbers of the vectors can be used to determine the processing matrix. The root sequence can be carried in the reference signal.

[0051] In some embodiments, the processing mode indication information indicates the processing matrix by a reference signal set to which the reference signal belongs.

[0052] The first communication node and the second communication node pre-agree the processing matrix corresponding to different reference signal sets, and the reference signal set can include at least one reference signal. After determining the processing matrix, the first communication node can select and send a reference signal from the reference signal set corresponding to the processing matrix, and after receiving the reference signal, the second communication node determines the processing matrix according to the reference signal set to which the reference signal belongs and processes the measurement result accordingly.

[0053] In some embodiments, the method further comprises: sending downlink signaling, the downlink signaling being used to indicate the category of the measurement result.

[0054] The first communication node can also send downlink signaling to the second communication node, and the downlink signaling can indicate the category of the measurement result. The second communication node can perform measurement according to the indication of the category of the measurement result in the downlink signaling, and determine the measurement result.

[0056] In some embodiments, the indication of the processing manner and the category of the measurement result can be indicated by the same downlink signaling, i.e., the first communication node can indicate the processing manner and the category of the measurement result by sending one downlink signaling. The indication of the processing manner and the category of the measurement result can also be indicated by different downlink signalings.

[0057] In some embodiments, the downlink signaling is sent before the reference signal is sent or after the reference signal is sent.

[0058] In some embodiments, the downlink signaling is periodically sent or sent after a trigger condition is met.

[0059] In some embodiments, the trigger condition is receiving a beam calibration request.

The measurement result processing method provided in the embodiments of the present application can process the measurement result without the transmission beam information of the reference signal, and will not affect the measurement accuracy.

[0065] In some embodiments, the processing mode indication information indicates the processing mode in at least one of the following manners: explicit indication, which is used for directly indicating the processing mode; or implicit indication, which is used for indicating the processing mode by means of inference or mapping.

[0066] In some embodiments, the explicit indication includes determining the processing mode through downlink signaling.

[0070] In some embodiments, the processing mode is a processing matrix, and the processing matrix includes at least one element.

[0071] In some embodiments, receiving the processing mode indication information includes at least one of the following: receiving all elements in the processing matrix; or receiving all elements in the quantized processing matrix.

The processing mode indication information can be received or determined in multiple ways, and the processing mode of the measurement result is flexibly determined. The flexible processing of the measurement result is realized, and the problem that the measurement result is difficult to process in the related art is effectively solved.

The measurement result processing method provided in the embodiments of the present application can process the measurement result without the transmission beam information of the reference signal, and the measurement accuracy is not affected.

[0091] The process of the measurement result processing is described in the following embodiments:

[0092] The first communication node can be a base station, and the second communication node can be a user equipment.

[0093] The process that the first communication node informs the second communication node of the reporting mode includes: the first communication node informs the second communication node of a measurement result processing mode of a reference signal, and the second communication node processes measurement results of multiple reference signals according to the processing mode informed by the first communication node. The reference signal can be a channel state information-reference signal (CSI-RS), a synchronization signal / physical broadcast channel block (SSB), a demodulation reference signal (DMRS), a cell reference signal (CRS), or the like.

[0094] Embodiment 1

[0095] The processing mode is explicitly informed.

[0096] The first communication node can directly inform the second communication node of the processing mode of the measurement result through downlink signaling. The downlink signaling can be a downlink broadcast message, such as information carried on a physical broadcast channel block. The downlink signaling can also be control signaling, including downlink control information (DCI), medium access control-control element (MAC-CE), and radio resource control (RRC) signaling.

[0097] If the processing mode is linear, the processing mode can be represented by a matrix, and therefore the first communication node can directly inform the second communication node of the processing matrix C through downlink signaling. For example, the following gives several explicit informing modes of the processing matrix.

[0098] Mode 1: The first communication node sends each element in the processing matrix C to the second communication node through signaling. For example, when the elements in the processing matrix are all integers, the first communication node can directly inform the second communication node of the processing matrix. When the elements in the processing matrix are not integers, the first communication node can quantize each element in the matrix and send the quantized elements to the second communication node.

[0099] Mode 2: The second communication node and the first communication node both preset K processing matrices, the first communication node informs the second communication node of the serial number of the processing matrix through signaling, and the second communication node processes the measurement result using the processing matrix corresponding to the serial number after receiving the signaling.

[0100] Method 3: The first communication node uses a set of basis vectors to linearly represent the processing matrix and notifies the second communication node of the selected basis vectors and their weight coefficients. The second communication node can then reconstruct the processing matrix based on the basis vectors and their coefficients. For example, suppose the processing matrix C is an M×N matrix composed of M 1×N row vectors, i.e., C = [c1; c2; ...; c...]. M The first communication node uses a set of 1×N basis vectors d1,d2,...,d K Alternatively, some of the basis vectors in this set of basis vectors can linearly represent each row vector in matrix C, where K ≥ N. For example, each column c in matrix C... m All are represented by L basis vectors, which are selected from a set of N basis vectors, as shown in the following formula.

[0101] The first communication node only needs to notify the linear representation c. m The coefficients a and the index k of the basis vectors d are sufficient. The second communication node has the same basis vectors pre-set. The second communication node can recover the processing matrix C based on the above coefficients and the index of the basis vectors.

[0102] Method 4: The notification method is similar to Method 3, but the processing matrix C is viewed as N M×1 column vectors C = [c1, c2, ..., c N The communication node is composed of K pre-set M×1 basis vectors d1, d2, ..., d... K Alternatively, some basis vectors in the group of basis vectors can linearly represent each column vector in matrix C.

[0103] Method 5: Assume the processing matrix C is an M×N matrix, and both the first and second communication nodes have K pre-set column vectors of length M×1, c1, c2, ..., c3. K The first communication node selects N columns from these K column vectors and notifies the second communication node of the sequence numbers of these N column vectors in the order of their arrangement. After receiving the sequence numbers, the second communication node combines these N column vectors into a matrix C, where K is an integer not less than N.

[0104] Method 6: The notification method is similar to Method 5, but the first and second communication nodes pre-configure K 1×N row vectors c1,c2,...,c K The first communication node selects M rows from these K row vectors and notifies the second communication node of the sequence numbers of these M row vectors in the order of arrangement. After receiving the sequence numbers, the second communication node combines these M row vectors into a matrix C, where K is an integer not less than M.

[0105] Example 2

[0106] The processing method is implicit notification.

[0107] The first communication node can implicitly include the processing matrix C in the reference signal, and the second communication node can deduce or map the processing matrix based on the reference signal after receiving it.

[0108] Method 1: Assume the first communication node sends M reference signals, each containing a root sequence of length N. After receiving these M reference signals, the second communication node can obtain the measurement results x = [x1, x2, ..., x...]. M And the root sequence c1, c2, ..., c of these M reference signals. M The M root sequences are arranged into an M×N matrix C according to the received order of the reference signal. This matrix is ​​the processing matrix for the reference signal. The second communication node arranges the M measurement results into a vector and multiplies it with matrix C to complete the processing of the reference signal measurement results.

[0109] Method 2: Assume the processing matrix C has dimensions M×N, and both the second and first communication nodes have pre-set K column vectors c1, c2, ..., c1 with dimensions M×1. K Let K be an integer not less than N. Assume the first communication node transmits N reference signals, each with a transmission sequence generated from a root sequence. Each reference signal's root sequence carries one index of a column vector c. After receiving the N reference signals, the second communication node can obtain the N indices from the root sequences and combine the corresponding column vectors into a processing matrix C according to the reception order of the reference signals. Similarly, the second and first communication nodes can also pre-define K row vectors of dimension 1×N. In this case, the first communication node transmits M reference signals, where K is an integer not less than N.

[0110] The processing method can also be related to the resource set where the reference signal is located.

[0111] Method 1: The second communication node sends M reference signals to the first communication node. These M reference signals belong to the same reference signal set k. Assuming there are K reference signal sets in total, then 1 ≤ k ≤ K. At this time, both the second and first communication nodes have K pre-set processing matrices C1, C2, ..., C... K Each reference signal set corresponds to a processing matrix. The second communication node can determine the processing matrix based on the reference signal set to which the received reference signal belongs. Furthermore, the number of reference signals and the dimension of the processing matrix may differ in different reference signal sets. Table 1 illustrates the relationship between different reference signal sets and the dimension of the processing matrix C, using four reference signal sets as an example.

[0112] Table 1 Reference signal set and corresponding processing matrix C example

[0113] In some embodiments, assuming that the reference signal set contains M reference signals, the dimension of the processing matrix C corresponding to the reference signal set is M x N, the first communication node can only send K reference signals, where K < M, and the second communication node obtains the measurement results of the K reference signals, selects K rows corresponding to the K reference signals from the processing matrix C to form a new processing matrix C1, and uses the processing matrix C1 to perform linear processing on the measurement results. For example, when the first communication node sends the first K reference signals in the reference signal set, the second communication node selects the first K rows of the processing matrix C to form C1.

[0114] When the processing method is notified by downlink signaling, the downlink signaling can be notified before or after the reference signal is sent. Figure 3A provides an example diagram of sending the reference signal first, in which the first communication node periodically sends M downlink reference signals, and after the downlink reference signals are sent, the first communication node sends downlink signaling to notify the second communication node of the joint processing method, and the second communication node performs local processing and reports the processing result. Figure 3B provides an example diagram of sending the reference signal later, in which the first communication node notifies the second communication node of the processing method and periodically sends M reference signals.

[0115] When the downlink signaling is notified after the reference signal is sent, the second communication node can only process and report the processing result of the measurement results of part of the reference signals. For example, the second communication node accesses the cell and starts beam training in the middle of the reference signal transmission, and only obtains the measurement results of part of the reference signals. When the signaling carrying the processing method is received, only the obtained measurement results are processed. Assuming that the second communication node has only received the last m reference signals of the M reference signals, the second communication node can take the last m rows of the processing matrix C to form a new processing matrix to process the measurement results.

[0116] The first communication node can also notify the second communication node of the processing method in an explicit and implicit combination. For example, the first communication node only notifies the second communication node of the number K of reference signals through downlink signaling, and the second communication node selects the continuous K reference signals for processing and reports the processing result. As described above, the processing matrix C is implicitly in the reference signal. The second communication node obtains the processing matrix C from the continuous K reference signals and processes the K reference signals.

[0117] In some cases, the downlink signaling is periodically sent. FIG. 4 provides an example diagram of periodically sending downlink signaling, the first communication node periodically sends downlink signaling and downlink reference signals, and the second communication node requiring beam training obtains measurement results of the reference signals, and then processes and reports the measurement results according to the processing mode indicated by the downlink signaling.

[0118] The downlink signaling can also be sent in a triggered manner. FIG. 5 provides an example diagram of sending downlink signaling in a triggered manner. As shown in FIG. 5, after receiving the beam calibration request sent by the second communication node, the first communication node sends downlink signaling to the second communication node. On the one hand, the downlink signaling can inform the second communication node that the beam calibration request is successfully received, and on the other hand, the processing mode is informed to the second communication node through the signaling. After receiving the downlink signaling, the second communication node starts to prepare to receive the downlink reference signals and starts to measure. If the second communication node does not receive the downlink signaling within a period of time T after sending the beam calibration request, the second communication node needs to resend the beam calibration request.

[0119] In some cases, the measurement results processed by the second communication node can have multiple categories, and the categories of the measurement results can be informed to the second communication node through the downlink signaling. The measurement results include Reference Signal Receiving Power (RSRP), Received Signal Strength Indication (RSSI), Reference Signal Receiving Quality (RSRQ), sample values of the received reference signals, average of multiple sample values, modulus of the received signals, square of the modulus of the received signals, or decibel values after taking logarithm of the above several measurement results.
