Description

Technical Field

[0001] This application relates to the field of wireless communication technologies, and particularly relates to a measurement method and apparatus. Background Art

[0002] To overcome the problem of large path loss of high-frequency millimeter waves, an array technology can be used between a network device and a terminal device to form a high-gain directional beam for communication, which can improve the antenna gain and compensate for the path loss. Before communication using a directional beam, beam training is required between the network device and the terminal device. The purpose of beam training is to find one or more appropriate transceiver beam pairs from multiple possible transceiver beam combinations.

[0003] Taking downlink beam training as an example, in the current new radio (NR) system, downlink beam training is achieved by the network device sending a reference signal and the terminal device measuring and / or feeding back the reference signal sent by the network device. Before beam training, the network device needs to send configuration information of the reference signal to the terminal device. The configuration information of the reference signal includes reference signal resource setting, which involves information such as the time, frequency, power, and port of the network device sending the reference signal, to ensure that the terminal device can correctly receive the reference signal according to the configuration information of the reference signal and perform measurements.

[0004] Since there are many transmitting beams of the network device, in the 3rd generation partnership project (3GPP) R15, it is stipulated that the network device can configure a maximum of 64 reference signal resources in a reference signal resource set, and a total of up to 128 reference signal resources can be configured. On the other hand, considering the different capabilities of different terminal devices, a terminal device capability reporting mechanism is stipulated in the protocol. When a terminal device accesses the network, it can report its capability to the network device.

[0005] Generally speaking, the network device needs to perform beam training-related configurations according to the capabilities reported by the terminal device. For example, if a terminal device reports that it can support a maximum of 8 reference signal resources, then the reference signal resource set configured by the network device for beam training can also include a maximum of 8 reference signal resources. In reality, the number of transmitting beams of the network device is much larger than 8, such as 64, which results in the network device having to continuously send radio resource control (RRC) signaling to the terminal device to update the reference signal resource set for beam training, which will bring a large system signaling overhead and delay. For example, it takes 10 - 100 ms for the terminal device to receive the RRC signaling and apply the reference signal resource set configured in the RRC signaling.

[0006] In summary, since the number of reference signal resources supported by the terminal device does not match the number of reference signal resources included in the set of reference signal resources configured by the network device for beam training, problems of signaling overhead and latency occur during the beam training process. Summary of the Invention

[0007] The purpose of the embodiments of the present application is to provide a measurement method and device to reduce signaling overhead and latency during beam training.

[0008] In a first aspect, an embodiment of the present application provides a measurement method, including: when the maximum number of supported reference signal resources is M, measuring M reference signal resources among N reference signal resources in a first resource period to obtain M signal measurement information, where N is an integer greater than 1 and M is an integer less than N; sending first information to the network device; the first information is used to indicate the M reference signal resources measured.

[0009] It can be seen from the above-described process that in the first resource period, when the number N of reference signal resources configured by the network device is greater than the maximum number M of reference signal resources supported by the terminal device, the network device does not need to reconfigure reference signal resources for the terminal device through signaling. The terminal device can only measure some of the reference signal resources configured by the network device, such as M reference signal resources, thereby reducing signaling overhead and latency, and also reducing the measurement burden of the terminal device. When the capabilities of the terminal device are limited, through measurements in multiple resource periods, the reference signal resources with the optimal signal measurement information can be obtained.

[0010] In a possible implementation, the method further includes: sending second information to the network device; the second information is used to indicate the reference signal resource corresponding to the optimal signal measurement information among the M signal measurement information.

[0011] In a possible implementation, the method further includes: sending third information to the network device. The third information is used to indicate the optimal signal measurement information among the M signal measurement information.

[0012] In a possible implementation, the first information is an offset value α corresponding to the first resource period, where α is the difference between the resource numbers of two reference signal resources with the same measurement order in the first resource period and the second resource period for the terminal device. The first resource period is the resource period corresponding to the first information, and the second resource period is the resource period before the first resource period and adjacent to the first resource period, or the second resource period is a preset resource period.

[0013] In a possible implementation, the first information includes bit positions or bit positions, and the bit positions or bit positions included in the first information correspond to the value of α; is floor function, is ceiling function;

[0014] Alternatively, the first information includes L bit positions, and the product of the values corresponding to the L bit positions included in the first information and a preset weight value is α; the preset weight value is an integer greater than 0, and there is a corresponding relationship between the preset weight value, N, and L.

[0015] In a possible implementation, measuring M reference signal resources among the N reference signal resources in the first resource period includes: measuring M reference signal resources with resource numbers from K + α to K + (M - 1) + α among the N reference signal resources; where K is the resource number of the starting reference signal resource among the M reference signal resources measured by the terminal device in the second resource period, α is an integer, the second resource period is the resource period before the first resource period and adjacent to the first resource period, or the second resource period is a preset resource period.

[0016] In a possible implementation, α is a value configured by the network device or a value determined by the terminal device.

[0017] In a possible implementation, α is equal to M.

[0018] In a possible implementation, measuring M reference signal resources among the N reference signal resources in the first resource period includes: randomly selecting M reference signal resources from the N reference signal resources for measurement.

[0019] In a possible implementation, the method further includes:

[0020] Sending capability indication information to the network device, where the capability indication information is used to indicate one or more of the following:

[0021] When the number of reference signal resources configured by the network device is greater than the maximum number of reference signal resources supported by the terminal device, measuring the reference signal resources configured by the network device;

[0022] In each resource period, the maximum number of reference signal resources that can be measured;

[0023] The maximum number of reference signal resources for which channel state information (CSI) can be calculated within each resource period;

[0024] The maximum number of measurement results of reference signal resources that can be stored within each resource period.

[0025] In a possible implementation, before measuring M reference signal resources out of N reference signal resources in the first resource period, the method further includes: receiving reporting quantity configuration information from the network device and resource configuration information associated with the reporting quantity configuration information;

[0026] The resource configuration information is used to indicate one or more of the following:

[0027] The N reference signal resources;

[0028] The number of resource periods Y for measuring the N reference signal resources, where Y is an integer less than N / M;

[0029] The offset value α corresponding to the first resource period; α is the difference between the resource numbers of two reference signal resources with the same measurement order in the first resource period and the second resource period, where the first resource period is the resource period corresponding to the first information, the second resource period is the resource period before the first resource period and adjacent to the first resource period, or the second resource period is a preset resource period;

[0030] Partial measurement indication information, used to indicate that when it is determined that the maximum number of reference signal resources that can be measured is less than the number N of reference signal resources configured by the network device, measure some of the N reference signal resources;

[0031] The reporting quantity configuration information is used to indicate that the terminal device reports one or more of the following:

[0032] The resource number of the reference signal resource corresponding to the optimal signal measurement information determined based on the M reference signal resources measured in each resource period, and the optimal signal measurement information;

[0033] α.

[0034] In a possible implementation, within the Y resource periods, the receiving beam used for measuring the reference signal resources remains unchanged.

[0040] As can be seen from the process described above, in the first resource period, when the number N of reference signal resources configured by the network device is greater than the maximum number of reference signal resources supported by the terminal device, the network device does not need to reconfigure the reference signal resources for the terminal device through signaling. The terminal device can only measure some of the reference signal resources configured by the network device, such as M reference signal resources, thereby reducing the signaling overhead and also reducing the measurement burden on the terminal device. This enables the terminal device to obtain the reference signal resources with the optimal signal measurement information after measurement in multiple resource periods when its capabilities are limited.

[0041] In a possible implementation, the first information is an offset value α corresponding to the first resource period, where α is the difference between the resource numbers of two reference signal resources with the same measurement order by the terminal device in the first resource period and the second resource period. The first resource period is the resource period corresponding to the first information, and the second resource period is the resource period before the first resource period and adjacent to the first resource period, or the second resource period is a preset resource period.

[0042] In a possible implementation, the first information includes bit positions or bit positions. The bit positions or bit positions included in the first information correspond to the value of α; is floor function, is ceiling function; or, the first information includes L bit positions, and the product of the values corresponding to the L bit positions included in the first information and a preset weight value is α; the preset weight value is an integer greater than 0, and there is a corresponding relationship between the preset weight value and N.

[0043] In a possible implementation, the method further includes: sending resource configuration information to the terminal device;

[0044] The resource configuration information is used to indicate one or more of the following:

[0045] The N reference signal resources;

[0046] The number of resource periods Y for measuring the N reference signal resources, where Y is an integer less than N / M;

[0047] The offset value α corresponding to the first resource period; α is the difference between the resource numbers of two reference signal resources with the same measurement order in the first resource period and the second resource period.

[0067] The technical solutions of the embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0068] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as: Global System of Mobile communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) communication system, 5th Generation (5G) system or New Radio (NR), etc., which are not limited herein.

[0069] To facilitate the understanding of the embodiments of the present application, first, Figure 1Taking the communication system shown as an example, the communication system applicable to the embodiments of the present application will be described in detail. Figure 1 FIG. shows the architecture of a possible communication system applicable to the method provided in the embodiments of the present application. The architecture of the communication system includes a network device and at least one terminal device, where: The network device can establish a communication link with at least one terminal device (such as the terminal device 1 and terminal device 2 shown in the figure) through beams in different directions. The network device can provide services related to wireless access for the at least one terminal device, and implement one or more of the following functions: wireless physical layer function, resource scheduling and wireless resource management, quality of service (QoS) management, radio access control, and mobility management function. The at least one terminal device can also form a beam for data transmission with the network device. In this embodiment, the network device and the at least one terminal device can communicate through beams.

[0070] It should be noted that Figure 1 The architecture of the shown communication system is not limited to only including the devices shown in the figure, and may also include other devices not shown in the figure. Specifically, the present application will not list them one by one here.

[0071] First, the definitions of technical terms that may appear in the embodiments of the present application will be given below.

[0072] Regarding the resource of the reference signal, in the embodiments of the present application, the resource where the network device sends the reference signal can be called the reference signal resource. The reference signal can be any one of the following signals: synchronization signal, broadcast channel, broadcast signal demodulation signal, channel state information downlink signal (CSI-RS), cell specific reference signal (CS-RS), user equipment specific reference signal (US-RS), downlink control channel demodulation reference signal, downlink data channel demodulation reference signal, downlink phase noise tracking signal, etc.

[0073] Beam: A beam is a communication resource. A beam can be a wide beam, a narrow beam, or other types of beams. The technology for forming a beam can be beamforming technology or other technical means. Beamforming technology can specifically be digital beamforming technology, analog beamforming technology, or hybrid digital / analog beamforming technology. Different beams can be considered different resources. The same information or different information can be transmitted through different beams. Optionally, multiple beams with the same or similar communication characteristics can be regarded as one beam. One beam can include one or more antenna ports for transmitting data channels, control channels, sounding signals, etc. For example, a transmit beam can refer to the distribution of signal strength formed in different directions in space after the signal is transmitted through the antenna, and a receive beam can refer to the distribution of signal strength of the wireless signal received by the antenna in different directions in space. It can be understood that one or more antenna ports forming a beam can also be regarded as an antenna port set. The manifestation of a beam in the protocol can still be a spatial filter.

[0074] Quasi-co-location (QCL): The co-location relationship is used to indicate that one or more of the same or similar communication characteristics exist between multiple resources. For multiple resources with a co-location relationship, the same or similar communication configurations can be adopted. For example, if two antenna ports have a co-location relationship, then the large-scale characteristics of the channel when one port transmits a symbol can be inferred from the large-scale characteristics of the channel when the other port transmits a symbol. The large-scale characteristics can include: delay spread, average delay, Doppler spread, Doppler shift, average gain, reception parameters, the receive beam number of the terminal device, transmit / receive channel correlation, angle of arrival, spatial correlation of the receiver antenna, main angle of arrival (Angel-of-Arrival, AoA), average angle of arrival, spread of AoA, etc.

[0075] The reference to "one embodiment" or "some embodiments" etc. described in this specification means that specific features, structures, or characteristics described in connection with the embodiment are included in one or more embodiments of the present application. Thus, the statements "in one embodiment", "in some embodiments", "in other some embodiments", "in still other embodiments", etc. that appear in different places in this specification do not necessarily all refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in another way. The terms "comprising", "including", "having" and their variants all mean "including but not limited to", unless otherwise specifically emphasized in another way.

[0076] In this application, "at least one" means one or more, and "a plurality of" means two or more. "And / or" describes the association relationship of associated objects and indicates that three relationships may exist. For example, A and / or B may indicate: A exists alone, A and B exist simultaneously, and B exists alone, where A and B may be singular or plural. The character " / " generally indicates that the associated objects before and after are in an "or" relationship. "At least one of the following" or a similar expression refers to any combination of these items, including any combination of single item or plural items. For example, at least one of a, b, or c may indicate: a, b, c, a - b, a - c, b - c, or a - b - c, where a, b, and c may be single or multiple.

[0077] In the embodiments of this application, the terminal device may refer to a user equipment, an access terminal, a user unit, a user station, a mobile station, a mobile terminal, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user device. The terminal device may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication function, a computing device, or other processing devices connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a future 5G network, or a terminal device in a future evolved Public Land Mobile Network (PLMN). The embodiments of this application do not limit this.

[0078] Exemplarily, the terminal device may include: a radio resource control (RRC) signaling interaction module, a media access control (MAC) signaling interaction module, and a physical (PHY) signaling interaction module. Among them, the RRC signaling interaction module may be a module for the network device and the terminal device to send and receive RRC signaling. The MAC signaling interaction module may be a module for the network device and the terminal device to send and receive MAC control element (CE) signaling. The PHY signaling and data may be a module for the network device and the terminal device to send and receive uplink control signaling or downlink control signaling, uplink and downlink data, or downlink data.

[0079] The network device in the embodiments of the present application may be a device for communicating with a terminal device. The network device may be a Base Transceiver Station (BTS) in a Global System of Mobile communication (GSM) system or a Code Division Multiple Access (CDMA) system, or a NodeB (NB) in a Wideband Code Division Multiple Access (WCDMA) system, or an Evolutional NodeB (eNB or eNodeB) in an LTE system, or a radio controller in a Cloud Radio Access Network (CRAN) scenario, or the network device may be a relay station, an access point, a vehicle-mounted device, a wearable device, and an access network device (such as a gNB) in a future 5G network or an access network device in a future evolved PLMN network, etc. The embodiments of the present application do not limit this.

[0080] Exemplarily, the network device may also include: an RRC signaling interaction module, a MAC signaling interaction module, and a PHY signaling interaction module.

[0081] In some deployments, a network device may include a centralized unit (CU) and a distributed unit (DU). The network device may also include an active antenna unit (AAU). The CU implements some functions of the network device, and the DU implements some functions of the network device. For example, the CU is responsible for processing non-real-time protocols and services, implementing radio resource control (RRC), and the functions of the packet data convergence protocol (PDCP) layer. The DU is responsible for processing physical layer protocols and real-time services, implementing the functions of the radio link control (RLC) layer, the media access control (MAC) layer, and the physical (PHY) layer. The AAU implements some physical layer processing functions, radio frequency processing, and related functions of active antennas. Since the information of the RRC layer will ultimately become the information of the PHY layer, or is transformed from the information of the PHY layer, therefore, in this architecture, high-layer signaling, such as RRC layer signaling, can also be considered to be sent by the DU, or sent by the DU + AAU. It can be understood that the network device may be a device including one or more of a CU node, a DU node, and an AAU node. In addition, the CU may be classified as a network device in the radio access network (RAN), or the CU may be classified as a network device in the core network (CN), and this application does not make a limitation on this.

[0082] The network architecture and service scenarios described in the embodiments of this application are for more clearly explaining the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided by the embodiments of this application. Those of ordinary skill in the art know that with the evolution of the network architecture and the emergence of new service scenarios, the technical solutions provided by the embodiments of this application are equally applicable to similar technical problems.

[0083] The embodiments of this application can be applied to the downlink beam training process, and the downlink beam training process generally may include the following processes:

[0084] Step 1: The network device configures a set of reference signal resources and indicates it to the terminal device.

[0085] Step 2: In each resource period, the network device sends a reference signal in each reference signal resource in the set of reference signal resources.

[0086] Among them, the network device can send reference signals using beams in different directions in different reference signal resources in the reference signal resource set. Of course, it is not necessarily required to send reference signals using beams in different directions in each reference signal resource. The reference signals can be sent using beams in the same direction in some reference signal resources, which will not be elaborated here.

[0087] Step 3: In each resource period, the terminal device measures some reference signal resources in the reference signal resource set, obtains the measurement results corresponding to the measured reference signal resources, and sends the measurement results to the network device.

[0088] In the embodiments of the present application, the measurement results reported by the terminal device in each resource period may include the optimal signal measurement information determined by the terminal device in this resource period, and information such as the reference signal resource corresponding to the optimal signal measurement information. The specific content of the signal measurement information can be referred to the following description, which will not be elaborated here.

[0089] After step 4, step 2, and step 3 are executed one or more times, the network device or the terminal device can select the optimal beam according to one or more measurement results measured by the terminal device in multiple periods. Subsequently, the network device and the terminal device can use the beam selected during the beam training process for communication.

[0090] The following will be combined with Figure 2 Describe the above process in detail. As Figure 2 shown, it is a schematic flowchart of a measurement method provided by the embodiments of the present application. Figure 2 In the process shown, taking the interaction between the terminal device and the network device as an example for illustration, the method provided by the embodiments of the present application can also be applied to other execution entities. For example, it can be a chip or module in the terminal device, and a chip or module in the network device. When the execution entity is a chip or module, it can refer to the following description, which will not be elaborated here. Refer to Figure 2 , this method includes:

[0091] Step 201: The terminal device sends capability indication information to the network device.

[0092] The capability indication information is used to indicate the capabilities of the terminal device. In a possible implementation, the capability indication information can be used to indicate one or more of the following:

[0093] 1. The terminal device can measure the reference signal resources configured by the network device when the number of reference signal resources configured by the network device is greater than the maximum number of reference signal resources supported by the terminal device;

[0094] Among them, the maximum number of reference signal resources supported by the terminal device may refer to the maximum number of reference signal resources that the terminal device reports and can measure within each resource period, or the maximum number of reference signal resources that can be used to calculate the channel state information (CSI), or the maximum number of measurement results of reference signal resources that can be stored, etc.

[0095] It should be noted that in the prior art, when the number of reference signal resources configured by the network device is greater than the maximum number of reference signal resources supported by the terminal device, since the terminal device is not sure which reference signal resources need to be measured, or the capabilities of the terminal device do not match the reference signal resources configured by the network device, the terminal device will consider that the network device configuration is incorrect, so the terminal device will not measure the reference signal resources. In this case, the terminal device may also feedback information indicating that the configuration is incorrect to the network device.

[0096] In the embodiments of the present application, even if the number of reference signal resources configured by the network device is greater than the maximum number of reference signal resources supported by the terminal device, the number of reference signal resources measured by the terminal device within each resource period is less than the number of reference signal resources configured by the network device.

[0097] 2. The maximum number of reference signal resources that the terminal device can measure within each resource period;

[0098] 3. The maximum number of reference signal resources that the terminal device can use to calculate the channel state information within each resource period;

[0099] 4. The maximum number of measurement results of reference signal resources that the terminal device can store within each resource period.

[0100] It should be noted that the maximum number of reference signal resources supported in the terminal device capability report may include the maximum number within a bandwidth part (BWP) / carrier component (CC) / CC group / band / band group, and may also include the maximum number across all BWP / CC / CC groups / band / band groups.

[0101] Optionally, the maximum number of reference signal resources supported in the terminal device capability report may include the configured number and may also include the activated number.

[0102] Optionally, the maximum number of supported reference signal resources in the terminal device capability report may include the number of reference signal resources for beam management, and may also include the number of reference signal resources for L1-RSRP, L1-RSRQ, and L1-SINR measurements.

[0103] Optionally, the maximum number of supported reference signal resources in the terminal device capability report may include the number of reference signal resources within each resource period, and may also include the number of reference signal resources within each measurement period or each measurement window, the number of reference signal resources within each reporting period, the number of reference signal resources within each time slot / each subframe / each frame, the number of reference signal resources within each unit time, and may also include the number of reference signal resources without time limit.

[0104] Optionally, the maximum number of supported reference signal resources in the terminal device capability report may include the number of reference signal resources for a single port, and may also include the number of reference signal resources for two ports.

[0105] Optionally, the maximum number of supported reference signal resources in the terminal device capability report may also be any combination of one or more of the above. For example, the maximum number of supported reference signal resources in the terminal device capability report may include the number of reference signal resources for a single port and two ports, the number of reference signal resources for a single port of one CC, the number of reference signal resources for two ports of all CCs, etc.

[0106] It should be noted that the above are only examples, and the capability indication information may also indicate other capabilities of the terminal device, which will not be elaborated here.

[0107] Exemplarily, after obtaining the capability indication information of the terminal device, the network device may configure the reference signal resources according to the capability indication information. For example, within each resource period, the maximum number of reference signal resources that the terminal device can measure is M, and the network device determines that the terminal device needs to measure Y resource periods. At this time, the number of reference signal resources N configured by the network device may be greater than or equal to M×N.

[0108] How the network device specifically configures the reference signal resources will not be elaborated in the embodiments of the present application.

[0109] Step 202: The network device sends the reporting quantity configuration information and the resource configuration information associated with the reporting quantity configuration information to the terminal device.

[0110] It should be noted that the network device may send the reporting quantity configuration information and the resource configuration information associated with the reporting quantity configuration information through high-layer signaling (such as RRC signaling), or may also send them in other ways. The embodiments of the present application do not limit this.

[0111] In the embodiments of the present application, the resource configuration information may be used to indicate one or more of the following:

[0112] 1. N reference signal resources. Specifically, it may indicate the time domain information and frequency domain information corresponding to each of the N reference signal resources, the transmission power and transmission ports of the reference signals in each reference signal resource, the resource period of the N reference signal resources, etc. N is an integer greater than 1. Of course, N may also have other value ranges. For example, N may also be an integer greater than 0, which will not be elaborated here.

[0113] It should be noted that when the resource configuration information is sent through signaling, for example, when the network device sends the resource configuration information through RRC signaling, from the perspective of the signaling, the network device will configure at least one reference signal resource set in the signaling, and the at least one reference signal resource set includes the N reference signal resources.

[0114] 2. The number of resource periods Y for measuring the N reference signal resources. Y is an integer less than N / M. M is the number of reference signal resources measured by the terminal device in each resource period.

[0115] 3. Partial measurement indication information, which is used to indicate that the terminal device measures some of the N reference signal resources.

[0116] 4. The offset value corresponding to at least one resource period. For the first resource period in at least one resource period, the offset value corresponding to the first resource period refers to the difference between the resource numbers of two reference signal resources with the same measurement order in the first resource period and the second resource period. The first resource period is the resource period in which the terminal device currently measures the reference signal resources. The second resource period is the resource period before the first resource period and adjacent to the first resource period, or the second resource period is a preset resource period.

[0117] Among them, the offset value corresponding to each resource period may be the same or different, and the embodiments of the present application do not limit this.

[0118] It should be noted that the terminal device sequentially measures M reference signal resources in each resource period. The i-th reference signal resource measured by the terminal device in the first resource period has the same measurement order as the i-th reference signal resource measured by the terminal device in the second resource period. For example, if the value of the offset α corresponding to the first resource period is 5, then when the number of the second reference signal resource measured by the terminal device in the second resource period is 10, the number of the second reference signal resource measured by the terminal device in the first resource period is 5.

[0119] It should be noted that when the offset value corresponding to each resource period can be a predefined value or a value determined by the terminal device, the network device may no longer indicate the offset value corresponding to the at least one resource period through the resource configuration information. Alternatively, when the offset value corresponding to the at least one resource period is a value determined by the terminal device, for the first resource period, the network device may re-determine the offset value corresponding to the first resource period according to the offset value corresponding to the first resource period reported by the terminal device, and indicate it through the resource configuration information.

[0120] It should be noted that when the offset value corresponding to the at least one resource period is determined by the network device, the network device may determine the offset value corresponding to one resource period at a time for the terminal device to measure the reference signal resource in the current resource period, or may determine the offset values corresponding to multiple resource periods at a time, and the specific quantity is not limited.

[0121] 5. The reporting period of the terminal device; after each measurement of the reference signal resource by the terminal device, a measurement result can be obtained. The network device may indicate the reporting period for the terminal device to report the measurement result. The reporting period of the terminal device may be the same as or different from the resource period, and the embodiments of the present application do not limit this.

[0122] Among them, when the reporting period of the terminal device is the same as the resource period, the terminal device reports the measurement result of each measurement in each resource period. When the reporting period of the terminal device is different from the resource period, there may be multiple situations. For example, the reporting period of the terminal device may be equal to Y resource periods. At this time, the terminal device may determine the optimal beam according to the Y optimal signal measurement information determined in the Y resource periods. For specific determination methods, reference can be made to the following description.

[0123] It should be noted that the above are only examples, and the resource configuration information may also indicate other configuration information of the reference signal resource, and no further examples will be given here one by one.

[0124] After receiving the resource configuration information, the terminal device can determine information such as the number of reference signal resources and the resource period configured by the network device according to the resource configuration information, so as to accurately measure the reference signal resource.

[0125] Furthermore, in the embodiments of the present application, the reporting quantity configuration information may be used to instruct the terminal device to report one or more of the following:

[0126] 1. The number of the reference signal resource corresponding to the optimal signal measurement information determined according to the M reference signal resources measured in each resource period, and the optimal signal measurement information.

[0127] It should be noted that in the embodiments of the present application, the signal measurement information includes, but is not limited to, any one of the following: layer 1 reference signal received power (L1-RSRP), layer 1 reference signal received quality (L1-RSRQ), received signal strength indication (RSSI), signal noise ratio (SNR), and signal to interference plus noise ratio (SINR), etc.

[0128] 2. The offset value corresponding to at least one resource period; it should be noted that when the offset value corresponding to the at least one resource period is a predefined value or a value determined by the network device, it may not be necessary to instruct the terminal device to report the offset value corresponding to the at least one resource period.

[0129] 3. The number of periods Y of the terminal device measuring the reference signal resources.

[0130] It should be noted that when the number of periods is a predefined value or a value determined by the network device, it may not be necessary to instruct the terminal device to report the number of periods.

[0131] It should be noted that the above are only examples, and the reporting quantity configuration information may also indicate other content that the terminal device needs to report, which will not be elaborated one by one here.

[0132] After steps 201 and 202 are completed, a beam training process can be performed between the network device and the terminal device. For details, refer to steps 203 to 205.

[0133] Step 203: In the first resource period, the network device sends a reference signal through each of the N reference signal resources among the N reference signal resources.

[0134] It should be noted that in each resource period, the network device can send N reference signals through the N reference signal resources. Here, only the first resource period is taken as an example, and the content executed by the network device in other resource periods can be the same as that in the first resource period, which will not be elaborated further.

[0135] Among them, the network device may send reference signals using beams in different directions in each reference signal resource, or may send reference signals using beams in the same direction in some reference signal resources and send reference signals using beams in different directions in some reference signal resources. The embodiments of the present application do not limit this.

[0136] The embodiments of the present application do not limit the specific implementation manner of the reference signal. For example, the reference signal may be CSI-RS, etc. The embodiments of the present application also do not limit how the network device specifically sends reference signals in the reference signal resources, and reference may be made to the descriptions in the prior art.

[0137] It should be noted that in each resource period, the N reference signal resources used by the network device to send reference signals may have the same frequency domain information, that is, they are in the same carrier component (CC) or the same bandwidth part (BWP), etc. For example, Figure 3 as shown, in the same carrier, the network device sends N reference signals through N reference signal resources in each resource period. Figure 3 In [the figure] only three resource periods from resource period 1 to resource period 3 are taken as examples for illustration, and other situations will not be elaborated.

[0138] In the embodiments of the present application, in any two resource periods, two reference signal resources with the same relative position have the same resource number. For example, Figure 3 in [the figure], the resource numbers of the N reference signal resources in resource period 1 are respectively 0 to N-1; the resource numbers of the N reference signal resources in resource period 2 are also respectively 0 to N-1. That is, the resource number of the first reference signal resource in resource period 1 is 0, and the resource number of the first reference signal resource in resource period 2 is also 0, etc.

[0139] Step 204: When the maximum number of reference signal resources supported by the terminal device is M, measure M reference signal resources among the N reference signal resources in the first resource period to obtain M signal measurement information.

[0140] Among them, N is an integer greater than 1, and M is an integer less than N. Each of the N reference signal resources includes a reference signal sent by the network device. The terminal device may determine the N reference signal resources according to the indication of the network device, such as the resource configuration information in step 202, etc.

[0141] It should be noted that the maximum number of reference signal resources supported by the terminal device is M, which may refer to the maximum number of reference signal resources that the terminal device can measure within each resource period is M, or the maximum number of reference signal resources for which the terminal device can calculate the channel state information is M, or the maximum number of measurement results of reference signal resources that the terminal device can store is M, etc. The embodiments of the present application do not limit this.

[0142] It should be noted that when the terminal device measures the reference signal resources, it may refer to measuring the reference signals in the reference signal resources. Specifically how to perform the measurement is not limited in the embodiments of the present application. For details, reference can be made to the descriptions in the prior art and will not be elaborated here.

[0143] In the embodiments of the present application, since the number N of reference signal resources configured by the network device is greater than the maximum number of reference signal resources that the terminal device can measure in one resource period, the terminal device can determine the M signal reference resources to be measured in multiple ways.

[0144] In the first possible implementation manner, in the first resource period, the terminal device measures M reference signal resources with resource numbers from K + α to K + (M - 1) + α among the N reference signal resources; where K is the resource number of the starting reference signal resource among the M reference signal resources measured by the terminal device in the second resource period, and α is the offset value corresponding to the first resource period, and α is an integer. Here, the second resource period is the resource period before the first resource period and adjacent to the first resource period, or the second resource period is a preset resource period, or the second resource period is any resource period before the first resource period.

[0145] For example, α is equal to 5. In the second resource period, the resource numbers of the M reference signal resources measured by the terminal device are 0 to M - 1 respectively; then in the first resource period, the resource numbers of the M reference signal resources measured by the terminal device are 5 to M - 1 + 5 respectively. For other resource periods, the M reference signal resources to be measured can be determined according to the offset value corresponding to the resource period, which will not be elaborated here.

[0146] It should be noted that as mentioned above, α can be a value configured by the network device, or a value determined by the terminal device. Of course, α can also be a value agreed upon between the network device and the terminal device.

[0147] When α is a value determined by the terminal device, the terminal device can randomly determine a value as α. By randomly determining a value as α, it can ensure that the terminal device measures the reference signal resource with the optimal signal quality among the N reference signal resources with the highest probability.

[0148] The terminal device can also determine the value of α in other ways. For example, the terminal device can use historical information to determine α. For example, the reference signal resource number corresponding to the received beam of the downlink physical channel or signal that the terminal device is currently using or used most recently (referred to as the serving beam), or the reference signal resource number corresponding to the transmitted beam of the uplink physical channel or signal that the terminal device is currently using or used most recently (referred to as the serving beam), is used as a reference for the initial measurement of α. Specifically, if the serving beam of the terminal device is the beam corresponding to the reference signal with a reference signal resource number of 10, then in the first resource period, α = 10, and the terminal device measures the reference signal resources with reference signal resource numbers from 10 to 9 + M. Additionally, if the serving beam changes between the j-th resource period and the previous resource period, then the terminal device can use this change value as a reference for α. Specifically, if the serving beam of the terminal device in the j-th resource period is the beam corresponding to the reference signal resource with a reference signal resource number of 10, and the serving beam in the previous resource period is the beam corresponding to the reference signal resource with a reference signal resource number of 15, then the terminal device can determine that α = 5.

[0149] Optionally, the terminal device can also use channel information to determine α. For example, the terminal device uses the channel estimation result to determine the strongest top Y paths for communicating with the network device as a reference for α. Specifically, the reference signal resource number corresponding to the strongest path is used as α in the first resource period, and the difference between the resource number corresponding to the strongest path and the reference signal resource number corresponding to the second-strongest path is used as α in the second resource period. The difference between the reference signal resource number corresponding to the strongest path in the j-th resource period and the reference signal resource number corresponding to the strongest path in the previous resource period is used as α in the j-th resource period.

[0150] Optionally, the terminal device can use positioning information to determine α. For example, the terminal uses the deviation between its relative position with the network device and the relative position in the previous resource period as a reference for α.

[0151] Optionally, the terminal device can use sensor information to determine α. For example, the terminal uses the gyroscope to determine the deviation between its own attitude and the own attitude in the previous resource period as a reference for α.

[0152] Optionally, the terminal device can use the correlation between beams to determine α. For example, the correlation between the beam corresponding to the reference signal resource number in the j-th resource period and the beam corresponding to the reference signal resource number in the previous resource period is the largest or the smallest.

[0153] It should be noted that when the offset value corresponding to each resource period is determined by the terminal device, the terminal device can determine the offset value corresponding to one resource period at a time for measuring the reference signal resources in the current resource period, or can determine the offset values corresponding to multiple resource periods at a time, and the specific quantity is not limited.

[0154] In the first possible implementation manner, in different measurement periods, the terminal device may measure the reference signal resources with the same resource number. For example, when M is equal to 8 and α is equal to 6, in the first resource period, the terminal device measures 8 reference signal resources with resource numbers from 0 to 7 respectively; in the second resource period, the terminal device measures 8 reference signal resources with resource numbers from 6 to 13 respectively. In these two resource periods, the terminal device measures the reference signal resources with resource numbers 6 and 7 respectively.

[0155] In the first possible implementation manner, the network device may instruct the terminal device to perform measurements in Y resource periods, so as to limit the longest time for the terminal device to measure the reference signal resources, reduce the time consumed by beam training, and improve the efficiency of beam training.

[0156] As described above, Y may be an integer less than N / M. For example, if N is equal to 64 and M is equal to 8. If the terminal device measures the reference signal resources with different resource numbers in each resource period, then at least 8 measurements are required to measure all 64 reference signal resources once, resulting in a relatively long time-consuming for this measurement method. Considering the mobility of the terminal device, too long time consumption is also prone to problems such as channel aging and out-of-date measurement results, that is, even if the entire set is measured, the selected beam may not necessarily be the optimal one. In the embodiments of the present application, the network device may instruct the terminal to only measure Y = 4 times, so as to reduce the time required for measurement and improve the efficiency.

[0157] In the second possible implementation manner, in one resource period, the terminal device sequentially measures N reference signal resources in a fixed order.

[0158] In this case, the starting reference signal resource of the M reference signal resources measured by the terminal device in each resource period is adjacent to the ending reference signal resource of the M reference signal resources measured in the previous resource period.

[0159] For example, in the first resource period, the resource numbers of the M reference signal resources measured by the terminal device are from 0 to M - 1 respectively; in the second resource period, the resource numbers of the M reference signal resources measured by the terminal device are from M to 2M - 1 respectively; in the third resource period, the resource numbers of the M reference signal resources measured by the terminal device are from 2M to 3M - 1 respectively. For other resource periods, it can be inferred by analogy and will not be elaborated here.

[0160] The second possible implementation can be regarded as the case where α equals M in the first possible implementation.

[0161] In the third possible implementation, the terminal device can randomly select M reference signal resources from N reference signal resources for measurement.

[0162] Optionally, in each resource period, the M reference signal resources randomly selected by the terminal device are all different, that is, in any two resource periods, such as the first resource period and the second resource period, the resource numbers of the M reference signal resources selected by the terminal device in the first resource period are different from the resource numbers of the M reference signal resources selected by the terminal device in the second resource period.

[0163] For example, M equals 4. The terminal device selects the reference signal resources with resource numbers 1 and 3 for measurement in the first resource period; the terminal device selects the reference signal resources with resource numbers 6 and 8 for measurement in the second resource period; the terminal device selects the reference signal resources with resource numbers 5 and 7 for measurement in the third resource period, etc.

[0164] Optionally, in each resource period, some of the M reference signal resources randomly selected by the terminal device can be the same, which will not be elaborated here.

[0165] Exemplarily, in the embodiments of the present application, the M reference signal resources measured by the terminal device can be continuous reference signal resources or discontinuous reference signal resources, and the embodiments of the present application do not limit this.

[0166] In the embodiments of the present application, step 204 can be executed multiple times. For example, the network device instructs the terminal device to perform measurement in Y resource periods, and at this time, the terminal device needs to execute step 204 Y times.

[0167] Furthermore, in the Y resource periods, the receiving beam used by the terminal device for measuring the reference signal resources remains unchanged. It should be noted that the network device can instruct the terminal device to keep the receiving beam unchanged, or it can be agreed that the terminal device keeps the receiving beam unchanged, and the embodiments of the present application do not limit this.

[0168] Step 205: The terminal device sends the first information to the network device.

[0169] Wherein, the first information is used to indicate the M reference signal resources measured by the terminal device.

[0170] The terminal device may also send other information to the network device, for example, sending the second information and the third information to the network device. The second information is used to indicate the reference signal resource corresponding to the optimal signal measurement information among the M signal measurement information; the third information is used to indicate the optimal signal measurement information among the M signal measurement information measured by the terminal device within this resource period.

[0171] The first information, the second information, and the third information may be sent to the network device through the same message, or may be sent to the network device through different messages respectively. The embodiments of the present application do not limit this.

[0172] In a possible implementation manner, the optimal signal measurement information among the M signal measurement information may refer to the signal measurement information with the best signal quality indicated among the M signal measurement information. For example, if the signal measurement information is L1-RSRP, the larger the L1-RSRP, the better the signal quality. The terminal device may use the largest L1-RSRP among the M measured L1-RSRPs as the optimal L1-RSRP, that is, as the optimal signal measurement information.

[0173] In another possible implementation manner, the optimal signal measurement information among the M signal measurement information may refer to any signal measurement information among the M signal measurement information that is greater than a preset threshold. For example, if the signal measurement information is L1-RSRP, the terminal device may use any L1-RSRP among the M measured L1-RSRPs that is greater than the preset threshold as the optimal L1-RSRP, that is, as the optimal signal measurement information.

[0174] In an embodiment of the present application, in a possible implementation manner, when the reporting period of the terminal device is the same as the resource period, the terminal device may send the first information and the second information obtained by measurement to the network device in each resource period.

[0175] In another possible implementation manner, when the reporting period of the terminal device is different from the resource period, the terminal device may report multiple first information and multiple second information obtained by measuring multiple resource periods to the network device each time.

[0176] For example, if the reporting period of the terminal device is Y resource periods, after the terminal device measures the reference signal resources in the Y resource periods, it may obtain Y first information, Y second information, and Y third information. The terminal device may report the Y first information, Y second information, and Y third information to the network device at the same time.

[0177] In an embodiment of the present application, the terminal device may indicate the M reference signal resources measured by the terminal device in a resource period in multiple ways.

[0178] In the first possible implementation, the terminal device may send the resource numbers of the measured M reference signal resources to the network device.

[0179] In a possible implementation, the first information may be M resource numbers, which can directly indicate the M reference signal resources.

[0180] In another possible implementation, the first information includes N bits, and each bit corresponds uniquely to one of the N reference signal resources. For any one of the N reference signal resources, when the terminal device measures this reference signal resource, the value of the bit corresponding to this reference signal resource is 1; when the terminal device does not measure this reference signal resource, the value of the bit corresponding to this reference signal resource is 0. Of course, it can also be the other way around, when the terminal device measures this reference signal resource, the value of the bit corresponding to this reference signal resource is 0; when the terminal device does not measure this reference signal resource, the value of the bit corresponding to this reference signal resource is 1.

[0181] The above are just examples. In this case, there may be other implementations of the first information, which will not be elaborated here.

[0182] In the second possible implementation, the terminal device may send the difference α between the resource numbers of two reference signal resources with the same measurement order in two adjacent resource cycles to the network device, and the network device may determine the M reference signal resources measured by the terminal device according to α.

[0183] In this implementation, the first information may be α, thereby indirectly indicating the M reference signal resources.

[0184] In this implementation, there may be multiple implementations of the first information.

[0185] Method 1, the first information includes bit positions or bit positions, and the bit positions or bit positions included in the first information have corresponding values as α; is floor, is ceiling.

[0186] For example, if N takes the value of 8, then the first information includes 3 bit positions. When α takes different values, the first information can be as shown in Table 1.

[0187] Table 1

[0188]

[0189]

[0190] It should be noted that Table 1 is only an example. For other cases, reference can be made to the description here, which will not be elaborated further.

[0191] In the second method, the first information includes L bit positions, and the product of the values corresponding to the L bit positions included in the first information and the preset weight value is the α; the preset weight value is an integer greater than 0, and there is a corresponding relationship between the preset weight value and N and L.

[0192] For example, the preset weight value and N and L can satisfy the following corresponding relationship: X is the preset weight value.

[0193] Furthermore, in combination with the above example, when L is equal to 3, when N takes different values, the preset weight value can be as shown in Table 2.

[0194] Table 2

[0195]

[0196] Combined with Table 2, the corresponding relationship between the values corresponding to the L bit positions included in the first information and α can be as shown in Table 3.

[0197] Table 3

[0198]

[0199] Combined with Table 2 and Table 3, when N takes the value of 8 and the first information is 010, it means that the value of α is 2×1 = 2.

[0200] When N takes the value of 15 and the first information is 010, it means that the value of α is 2×2 = 4.

[0201] When N takes the value of 24 and the first information is 010, it means that the value of α is 2×3 = 6. Other cases can be deduced by analogy and will not be elaborated further.

[0202] In the third possible implementation method, the first indication information can be P offset values, where P is an integer greater than 2 and less than or equal to M. Each of the P offset values indicates the difference between the resource numbers of two reference signal resources with the same measurement order in adjacent two resource periods of the terminal device.

[0203] For example, when M is 4 and P is equal to M, the terminal device selects the reference signal resources with resource numbers 1, 3, 4, and 7 for measurement in the first resource period; the terminal device selects the reference signal resources with resource numbers 6, 8, 12, and 14 for measurement in the second resource period. Then, in the second resource period, the 4 offset values reported by the terminal device can be 5 = 6 - 1, 5 = 8 - 3, 8 = 12 - 4, and 7 = 14 - 7, respectively. Other cases can be deduced by analogy and will not be elaborated here.

[0204] Step 206: The network device receives the first information from the terminal device and determines the M reference signal resources according to the first information.

[0205] The network device may also receive information such as the second information and the third information from the terminal device.

[0206] In a possible implementation, when the reporting period of the terminal device is the same as the resource period, the terminal device sends the first information, the second information, and the third information obtained by measurement to the network device in each resource period.

[0207] When the number of resource periods for the terminal device to measure the reference signal resources is Y, the terminal device may send a first information, a second information, and a third information to the network device in each of the Y resource periods, sending a total of Y first information, Y second information, and Y third information.

[0208] In another possible implementation, when the reporting period of the terminal device is different from the resource period, the terminal device may report multiple first information, multiple second information, and multiple third information obtained by measuring multiple resource periods to the network device each time.

[0209] For example, when the reporting period of the terminal device is Y resource periods, after the terminal device measures the reference signal resources in the Y resource periods, it can obtain Y first information, Y second information, and Y third information, and the terminal device can report the Y first information, Y second information, and Y third information to the network device simultaneously.

[0210] After the network device obtains the Y first information, Y second information, and Y third information measured by the terminal device in the Y resource periods, it can determine which reference signal resources the terminal device measures in the Y resource periods according to the Y first information. The network device can determine the Y reference signal resources with the best signal measurement information among the N reference signal resources according to the Y second information.

[0211] The network device selects one signal measurement information from the Y signal measurement information indicated by the Y third information as the globally optimal signal measurement information, and uses the beam direction used when transmitting the reference signal in the reference signal resource corresponding to the globally optimal signal measurement information as the optimal beam direction.

[0212] The embodiments of the present application do not limit how the network device specifically determines the globally optimal signal measurement information. For example, in a possible implementation, the network device uses the signal measurement information with the best signal quality among the Y signal measurement information indicated by the Y third information as the globally optimal signal measurement information. For example, the signal measurement information is L1-RSRP, and the larger the L1-RSRP, the better the signal quality. The network device obtains Y L1-RSRPs indicated by the Y third information. The network device can use the largest L1-RSRP among the Y L1-RSRPs as the globally optimal L1-RSRP.

[0213] In another possible implementation, the network device can use any signal measurement information greater than a preset threshold among the Y signal measurement information indicated by the Y third information as the globally optimal signal measurement information. For example, the signal measurement information is L1-RSRP, and the network device can use any L1-RSRP greater than the preset threshold among the Y L1-RSRPs as the globally optimal L1-RSRP.

[0214] After the beam training process is completed, the network device can use the optimal beam direction to send downlink data to the terminal device.

[0215] From the process described above, it can be seen that when the number of reference signal resources configured by the network device is greater than the maximum number of reference signal resources supported by the terminal device, the network device does not need to reconfigure the reference signal resources for the terminal device through signaling. The terminal device can only measure some of the reference signal resources configured by the network device, thereby reducing the signaling overhead and the measurement burden of the terminal device, enabling the terminal device to obtain the reference signal resource with the optimal signal measurement information after measuring for multiple resource cycles under the condition of limited capabilities.

[0216] It should be noted that when the reference signal resources configured by the network device are distributed in a two-dimensional coordinate plane, the embodiments of the present application are still applicable. At this time, α indicated by the first information can be replaced by a two-dimensional coordinate value, and other contents are applicable and will not be elaborated here. Among them, the distribution of the reference signal resources configured by the network device in the two-dimensional coordinate plane can be referred to Figure 4 as shown. Figure 4In this case, 32 reference signal resources of the network device are used as an example for illustration.
