[0104] In new radio (NR), especially when the frequency range (FR) is FR2, due to fast attenuation of high frequency channels, in order to ensure coverage, beam-based transmission and reception need to be used.

[0105] In a conventional beam management process, a base station configures a set of reference signal resources for beam measurement, a terminal measures the reference signal resources in the set of reference signal resources, and then reports the identities (IDs) and corresponding Layer 1 reference signal received power (L1-RSRP) and / or Layer 1 Signal to Interference plus Noise Ratio (L1-SINR) of X reference signal resources with relatively strong signals. The problem with the conventional method is that the set of reference signal resources configured by the base station includes Y reference signal resources, each of which corresponds to a different transmission beam of the base station. For each reference signal resource, the terminal needs to use all reception beams to measure the reference signal resource and obtain the beam measurement quality corresponding to each reception beam, and determine the best beam measurement quality. Therefore, the terminal needs to measure M*N beam pairs, where M is the number of transmission beams of the base station and N is the number of reception beams of the terminal.

[0106] The following explains the specific process of beam information output by an AI model and beam information obtained by a conventional method.

[0107] The beam prediction principle based on an AI model is as follows:

[0108] For spatial domain prediction, the terminal measures the L1-RSRP (which may also include the ID of a beam or a beam pair) of set B, inputs it into an AI model, and predicts the L1-RSRP of set A or the best beam ID of set A. The relationship between set B and set A includes the following two cases:

[0109] First, set B and set A are subsets. For example, set A includes 32 reference signal resources (each reference signal resource corresponds to a beam direction), and set B includes N reference signal resources, such as N = 8. The above only considers transmission beams. If beam pairs are considered, the reception beams of the terminal also need to be considered. For example, 32 transmission beams and 4 reception beams of the terminal, so set A is 32*4 beam pairs; set B can be 32 beam pairs, 16 beam pairs, etc. Among them, * is the multiplication sign.

[0110] Second, set B is wide beam and set A is narrow beam. For example, set A contains 32 reference signal resources (each reference signal resource corresponds to a beam direction, and 32 reference signal resources cover 120 degrees of direction). Set B contains another N reference signal resources, such as N = 8, and the N reference signal resources also cover 120 degrees of direction, that is, the beam direction of each reference signal in set B covers the beam direction of multiple reference signal resources in set A. It can be understood that 32 / N reference signal resources in set A and the same reference signal resource in set B have a quasi co location (QCL) type (Type D) relationship.

[0111] If it is assumed that the AI model has been trained in advance, the base station only needs to periodically send the reference signal resources of set B, and then the terminal measures the L1-RSRP of the reference signals in set B and inputs it into the AI model, which can output the L1-RSRP of all beams or beam pairs of set A or output the strongest X reference signal resource IDs or beam pair IDs in the 32 reference signal resources in set A.

[0112] However, if data collection for AI model training is required, in addition to sending set B, the base station is also required to periodically send the reference signal resources of set A, and then the terminal measures the results of set B and reports them to the base station as the input of the base station side model, while also measuring the L1-RSRP of all reference signal resources in set A and reporting the L1-RSRP of the reference signals in set A to the base station or obtaining the best reference signal resource ID based on the L1-RSRP of the reference signals in set A and reporting it to the base station. Of course, if set B is a subset of set A, it is equivalent to the terminal only needing to measure all beams or beam pairs of set A.

[0113] In the conventional report configuration for beam measurement, only the actual reference signal resource set to be measured is included.

[0114] For time domain beam prediction, the terminal actually measures set B at a historical time, and needs to report the beam report of set A at a future time. Moreover, the terminal needs to measure multiple set B at historical times for model input, and therefore how to configure the time corresponding to the reference signal resources of set B is a problem to be solved.

[0115] Therefore, the present disclosure provides a communication method, which comprises receiving, by a terminal, first configuration information sent by a network device, wherein the first configuration information comprises configuration information of a first reference signal resource set, and the first reference signal resource set corresponds to at least one first transmission occasion, so as to determine a first transmission occasion for measuring the first reference signal resource set.

[0127] FIG. 2a is a schematic diagram of an interaction of a communication method according to an embodiment of the present disclosure. As shown in FIG. 2a, the embodiment of the present disclosure relates to a communication method for a communication system 100, the method comprising:

[0128] In step S2101, the network device 102 sends first configuration information to the terminal 101.

[0129] In some embodiments, the terminal 101 receives the first configuration information sent by the network device 102.

[0130] In some embodiments, the first configuration information includes configuration information of a first reference signal resource set. The first reference signal resource set is used for beam measurement. The terminal can measure at least one reference signal resource in the first reference signal resource set on a first transmission occasion to obtain a beam measurement result. Based on the beam measurement result, a beam prediction result at a future time can be predicted. For example, the beam measurement result can be input into an AI / ML model, and the output of the AI / ML model is the beam prediction result.

[0131] In some embodiments, the first reference signal resource set can be set B, and the measurement result of the first reference signal resource set is used for input of a time-domain beam prediction model.

[0132] In some embodiments, the beam measurement result includes at least one of the following: a first identifier, the first identifier being an identifier of the at least one reference signal resource in the first reference signal resource set; a second identifier, the second identifier being an identifier of a beam corresponding to the at least one reference signal resource in the first reference signal resource set; a layer 1 reference signal received power L1-RSRP, the L1-RSRP being an L1-RSRP of the at least one reference signal resource in the first reference signal resource set; and a layer 1 signal to interference plus noise ratio L1-SINR, the L1-SINR being an L1-SINR of the at least one reference signal resource in the first reference signal resource set.

[0133] In some embodiments, the beam prediction result includes at least one of the following: a third identifier, the third identifier being an identifier of the at least one reference signal resource in the second reference signal resource set; a fourth identifier, the fourth identifier being an identifier of a beam corresponding to the at least one reference signal resource in the second reference signal resource set; a layer 1 reference signal received power L1-RSRP, the L1-RSRP being an L1-RSRP of the at least one reference signal resource in the second reference signal resource set; and a layer 1 signal to interference plus noise ratio L1-SINR, the L1-SINR being an L1-SINR of the at least one reference signal resource in the second reference signal resource set.

[0134] In some embodiments, the present disclosure takes the beam measurement result as an example for the following introduction, but the same applies to the beam prediction result:

[0135] Optionally, the beam measurement result can comprise an identity of the at least one reference signal resource in the first set of reference signal resources, which is referred to as a first identity in the present disclosure, but the name is not limited thereto. For example, the beam corresponding to the certain or certain ones of the reference signal resources in the first set of reference signal resources is the best beam in the measurement, and the beam measurement result can comprise the identity of the reference signal resource. Of course, the present disclosure is not limited thereto, for example, the beam corresponding to the certain or certain ones of the reference signal resources in the first set of reference signal resources can be the worst beam in the measurement, and the beam measurement result can comprise the identity of the reference signal resource.

[0136] Optionally, the beam measurement result can comprise an identity of the at least one reference signal resource in the first set of reference signal resources, which is referred to as a first identity in the present disclosure, but the name is not limited thereto. For example, the beam corresponding to the certain or certain ones of the reference signal resources in the first set of reference signal resources is the best beam in the measurement, and the beam measurement result can comprise the identity of the reference signal resource. Of course, the present disclosure is not limited thereto, for example, the beam corresponding to the certain or certain ones of the reference signal resources in the first set of reference signal resources can be the worst beam in the measurement, and the beam measurement result can comprise the identity of the reference signal resource.

[0137] Optionally, the beam measurement result can comprise an L1-RSRP of the at least one reference signal resource in the first set of reference signal resources. The L1-RSRP of the reference signal resource can represent the quality of the beam corresponding to the reference signal resource. The terminal can measure the L1-RSRP of the at least one reference signal resource in the first set of reference signal resources.

[0138] Optionally, the beam measurement result can comprise an L1-SINR of the at least one reference signal resource in the first set of reference signal resources. The L1-SINR of the reference signal resource can represent the quality of the beam corresponding to the reference signal resource. The terminal can measure the L1-SINR of the at least one reference signal resource in the first set of reference signal resources.

[0139] In some embodiments, the number of the first set of reference signal resources is one. For example, the first transmission occasion can be one or more. If the first transmission occasion is one, the terminal can measure the reference signal resources in one first set of reference signal resources on one first transmission occasion. If the first transmission occasion is multiple, the terminal can measure the reference signal resources in the same first set of reference signal resources on multiple first transmission occasions. That is, the terminal can perform multiple measurements on the reference signal resources in the same first set of reference signal resources to obtain the beam measurement result.

[0140] In some embodiments, the transmission time corresponding to different transmission occasions is different. If a certain transmission occasion corresponds to the transmission of a first reference signal resource set, the transmission occasion contains the time slots and / or symbols occupied by all reference signal resources in the first reference signal resource set. That is, the transmission occasion corresponds to at least one time slot, or at least one symbol, that is, it can correspond to multiple time slots, or multiple symbols. Or it can be understood that the transmission occasion corresponds to the transmission time of a transmission burst, and a transmission burst contains the transmission of all reference signal resources in a reference signal resource set.

[0141] In some embodiments, the number of first reference signal resource sets is multiple. For example, the first transmission occasion can be one or more. If the first transmission occasion is one, the terminal can measure the reference signal resources in multiple first reference signal resource sets on one first transmission occasion. If the first transmission occasion is multiple, the terminal can measure the reference signal resources in different first signal resource sets on multiple first transmission occasions respectively. Each first transmission occasion corresponds to a first reference signal resource set.

[0142] It can be understood that the reference signal resources in the first reference signal resource set described in the present disclosure can be one reference signal resource, or multiple reference signal resources. It can be part of the reference signal resources, or all of the reference signal resources. For example, the terminal measuring the reference signal resources in the first reference signal resource set means that the terminal measures at least one reference signal resource in the first reference signal resource set.

[0143] In some embodiments, the first transmission occasion is determined based on the first configuration information.

[0144] Optionally, if the number of the first reference signal resource sets is one, the first configuration information can include at least one of T1, N and M. Wherein, T1 represents a period of a single second transmission occasion. N represents the number of the second transmission occasions, and M represents the number of the first transmission occasions, and the M first transmission occasions are the first M of the N second transmission occasions. The terminal can determine the N second transmission occasions according to T1 and N, and determine the first M of the N second transmission occasions as the first transmission occasions. Wherein, the specific values of M, N and T1 are not limited by the present disclosure. FIG. 2b is a schematic diagram of the first transmission occasion and the second transmission occasion according to an embodiment of the present disclosure. As shown in FIG. 2b, 6 second transmission occasions are determined based on T1 and N, and the first 4 of the second transmission occasions are determined as the first transmission occasions. The oblique dotted circles representing the first transmission occasions and the solid circles representing the second transmission occasions overlap in FIG. 2b, indicating that the second transmission occasion is determined as the first transmission occasion. Wherein, the starting position of the first T1 may, for example, be the position of receiving the first configuration information, and may, for example, be the position of receiving the first configuration information after an interval of a preset offset, which is not limited by the present disclosure. The second transmission occasion can be understood as a transmission occasion to be used, and the first transmission occasion can be determined from the second transmission occasion for measuring at least one reference signal resource in the first reference signal resource set. And the beam results corresponding to the last two of the 6 second transmission occasions can be obtained based on the AI / ML model of the time domain beam prediction, and the input of the model includes the beam measurement results corresponding to at least one reference signal resource in the first reference signal resource set on the 4 first transmission occasions.

[0145] Optionally, if the number of the first reference signal resource sets is one, the first configuration information can include at least one of T1, T2 and M. Wherein, T1 represents the period of a single second transmission occasion, T2 represents the period of multiple second transmission occasions, and M represents the number of the first transmission occasions, and the M first transmission occasions are the first M transmission occasions of the multiple second transmission occasions. That is, the number of the second transmission occasions can not be included in the first configuration information, but the period of the multiple second transmission occasions is included, and according to the period T2 of the multiple second transmission occasions and the period T1 of a single second transmission occasion, the number of the second transmission occasions can be indirectly determined. For example, the number of the second transmission occasions in T2 is N, that is, T2 / T1=N. The first transmission occasions can be the first M of the N second transmission occasions. FIG. 2c is a schematic diagram of the first transmission occasion and the second transmission occasion according to an embodiment of the present disclosure. As shown in FIG. 2c, the N second transmission occasions are included in T2, and the first M can be determined as the first transmission occasions. The solid circles representing the second transmission occasions and the diagonal lines representing the first transmission occasions overlap in FIG. 2c, indicating that the second transmission occasion is determined as the first transmission occasion. Wherein, for example, the starting position of the first T1 can be the position of receiving the first configuration information, or can be the position of receiving the first configuration information after an interval of a preset offset value, which is not limited in the present disclosure. The second transmission occasion can be understood as a transmission occasion to be used, and the first transmission occasion can be determined from the second transmission occasion for measuring at least one reference signal resource in the first reference signal resource set. And the beam results corresponding to the last two of the six second transmission occasions can be obtained based on the AI / ML model of the time domain beam prediction, and the input of the model includes the beam measurement results corresponding to at least one reference signal resource in the first reference signal resource set on the four first transmission occasions.

[0146] Optionally, if the number of the first reference signal resource sets is one, the first configuration information can comprise at least one of T2 and a first offset value. T2 represents a period of the multiple first transmission occasions. The first offset value is an offset value of the first transmission occasion within T2. The number of the first offset value can be one or more. For example, one first offset value is an offset value of a first transmission occasion corresponding to the first reference signal resource set within T2. The multiple first offset values comprise offset values of respective first transmission occasions corresponding to the first reference signal resource set within T2. For example, assuming that the multiple first offset values are offset 1, offset 2, and offset 3, respectively. The position of the first first transmission occasion is obtained by adding offset 1 to the start position of T2, the position of the second first transmission occasion is obtained by adding offset 2 to the start position of T2, and the position of the third first transmission occasion is obtained by adding offset 3 to the start position of T2. It can be understood that the disclosure takes three first offset values as an example, but is not limited thereto. Offset 2 can also be represented as offset 1 plus T1, and offset 3 can also be represented as offset 2 plus T1. For example, the three first offset values exemplified in the embodiment can be offset 1, (offset 1+T1), and (offset 1+2*T1), respectively, where * is a multiplication sign.

[0147] Optionally, if the number of the first reference signal resource sets is one, the first configuration information can comprise at least one of T2 and a first offset value. T2 represents a period of the multiple first transmission occasions. The first offset value is an offset value of the first reference signal resource in the first reference signal resource set within T2. For example, the slot of the first reference signal resource is obtained by adding the first offset value to the start position of T2. The transmission occasion in which the slot of the first reference signal resource is located can be determined as the first transmission occasion. The first offset value can be one or more, and each first offset value can determine the slot of one first reference signal resource, thereby determining one first transmission occasion. Based on the multiple first offset values, multiple first transmission occasions can be determined. The first offset value can also be a symbol offset value of the first reference signal resource. For example, the symbol of the first reference signal resource is obtained by adding the first offset value to the start position of T2, and the transmission occasion in which the symbol of the first reference signal resource is located can be determined as the first transmission occasion.

[0148] Optionally, if the number of the first reference signal resource sets is one, the first configuration information can include at least one of T2 and a first offset value. T2 represents a period of the multiple first transmission occasions. The first offset value is an offset value of the first reference signal resource in the first reference signal resource set. For example, a slot of the first reference signal resource is obtained by adding the first offset value to a starting position of T2. Since the number of the first reference signal resource sets is one, the reference signal resource set needs to be transmitted in the multiple first transmission occasions, and therefore each first reference signal resource can correspond to multiple offset values, respectively corresponding to different first transmission occasions. In this case, the slot corresponding to the reference signal resource to be measured is directly determined, and therefore the first transmission occasion does not need to be determined first, and then the slot corresponding to the reference signal resource in each transmission occasion is further determined.

[0149] Optionally, if the number of the first reference signal resource sets is multiple, the first configuration information includes at least one of T2 and a second offset value. T2 represents a period of the multiple first transmission occasions, and the second offset value is an offset value of the first transmission occasion in T2. For example, the first transmission occasion is obtained by adding the second offset value to a starting position of T2. The second offset value can be one or multiple, and based on the multiple second offset values, the multiple first transmission occasions can be determined. The second offset value can be related to a slot, a symbol, or T1, where T1 is a period of a single second transmission occasion. Different reference signal resource sets correspond to different first transmission occasions. FIG. 2d is a schematic diagram of the first transmission occasion and the second transmission occasion according to an embodiment of the present disclosure. Taking an example in which the second offset value is a multiple of T1, as shown in FIG. 2d, starting from the starting position of T2, the second offset value is (n1+0*T1), and one first transmission occasion can be determined, which is the position where the first solid circle and the hatched circle overlap. The second offset value is (n1+1*T1), and one first transmission occasion can be determined, which is the position where the second solid circle and the hatched circle overlap. The second offset value is (n1+2*T1), and one first transmission occasion can be determined, which is the position where the third solid circle and the hatched circle overlap. The present disclosure does not list all examples.

[0150] In some embodiments, if the terminal determines the first transmission occasion based on T2 and the first offset value, since the first transmission occasion is indirectly determined based on a slot and / or a symbol, the terminal can no longer determine the slot and / or the symbol of the first reference signal resource.

[0151] In some embodiments, if the terminal determines the first transmission occasion based on other optional manners, the terminal can further determine the slots and / or symbols of the reference signal resources in the first reference signal resource set on the first transmission occasion. For example, as shown in FIG. 2b, after the terminal determines the first transmission occasion, the terminal can further determine the slots and / or symbols corresponding to each reference signal resource based on the slot (and / or symbol) offset value of the reference signal resource relative to the starting position of T1, and on the multiple first transmission occasions, the slots (and / or symbols) occupied by the positions of the first reference signal resources are the same. For example, the T1 period, the slots and / or symbols can be indicated by using a conventional method, and details are not described herein.

[0152] In some embodiments, the first configuration information includes at least one of the following: a channel state information reporting configuration (CSI-reportconfig); and a channel state information measurement configuration (CSI-MeasConfig).

[0153] In step S2102, the terminal 101 determines the first transmission occasion based on the first configuration information.

[0154] In some embodiments, the optional manner in which the terminal determines the first transmission occasion based on the first configuration information can refer to the embodiments of step S2101, and details are not described herein.

[0155] In some embodiments, the terminal can measure at least one first reference signal resource in the first reference signal resource set on the first transmission occasion to obtain a beam measurement result. Alternatively, the terminal can measure at least one first reference signal resource in the first reference signal resource set on the slots and / or symbols of the first transmission occasion to obtain a beam measurement result. The beam measurement result can be used as an input of the AI / ML model to predict a beam prediction result.

[0156] In some embodiments, the name of the first configuration information is not limited, and for example, the first information, etc.

[0178] FIG. 5 is an interaction diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG. 5, the embodiment of the present disclosure relates to a communication method, and the method comprises the following steps:

[0179] In step S5101, the network device 102 sends the first configuration information to the terminal 101.

[0180] In step S5102, the terminal 101 receives the first configuration information.

[0181] In some embodiments, the above method can include the method of the above embodiments related to the communication system 100, the terminal 101, and the network device 102, which are not described here.

[0182] The present disclosure provides a communication method, which comprises the following steps:

[0183] In some embodiments, the terminal receives the first configuration information of the network device, and the first configuration information comprises reference signal resource set configuration information, and the reference signal resource set comprises at least one first reference signal resource set (set B), and the at least one first reference signal resource set corresponds to at least one transmission occasion.

[0184] In some embodiments, the reference signal resource set comprises one first reference signal resource set, and the first configuration information indicates the transmission occasion corresponding to the one first reference signal resource set.

[0185] In some embodiments, referring to FIG. 2b, one reference signal resource set is indicated. The reference signal resource set is sent in the transmission occasion corresponding to the solid circle, and the position without the solid circle does not send the reference signal resource but needs to be predicted based on the beam prediction model. There are three indication methods:

[0186] The first one is to give the value of the period T1 (the number of slots occupied), and the first number N (the number of T1 within T2), and the second number M (the first M transmission occasions within the N transmission occasions will send the reference signal resource).

[0187] In addition, the transmission slot and symbol corresponding to each reference signal resource within the reference signal resource set on each transmission occasion can be indicated in the same way as the traditional method.

[0188] The second one is to give the value of the period T2 (the number of slots occupied), and the first number N and the second number M.

[0189] In addition, the transmission slot and symbol corresponding to each reference signal resource within the reference signal resource set on each transmission occasion can be indicated in the same way as the traditional method.

[0190] The third one is to give the value of the period T2, and then there is no need to give the time corresponding to each transmission occasion, but directly give the transmission slot and symbol corresponding to each reference signal resource within the reference signal resource set on each transmission occasion. The difference from the first two is that the first two give the position of each transmission occasion first, and then the slot and symbol of each reference signal resource in the reference resource set can be given relative to the transmission occasion corresponding to the reference signal resource set. This does not need to give the position of each transmission occasion.

[0191] In some embodiments, the reference signal resource set includes a plurality of first reference signal resource sets, and the first configuration information indicates the transmission occasions corresponding to the plurality of first reference signal resource sets.

[0192] In some embodiments, referring to FIG. 2d, a plurality of reference signal resource sets are indicated. The periods corresponding to the plurality of reference signal resource sets are the same, but the offsets of the transmission positions relative to the periods are different. Compared with FIG. 1, this method indicates one period, i.e., T2 (the number of slots occupied), and the offset (the number of slots or the number of T1) of the transmission occasion corresponding to each set B from the starting point of the period.

[0193] In addition, the transmission slot and the symbol corresponding to each reference signal resource in the set of reference signal resources on each transmission occasion can be indicated in the same way as in the conventional method.

[0194] In some embodiments, the first configuration information is CSI-reportconfig, and / or the first configuration information can be CSI-resourceconfig.
