Description

Method and device for beam management

Technical Field

The present application relates to the field of communications, and in particular, to a method and an apparatus for beam management.

Background

As the frequency of radio waves used for mobile communication increases, the path loss increases. Based on this fact, we can compensate for the high frequency path loss by increasing the number of antennas. Mobile communication systems using high frequency carriers will face the serious challenge of improving coverage and reducing interference, once the frequency exceeds 10GHz, diffraction is no longer the dominant signal propagation mode; for non-line-of-sight propagation links, reflection and scattering are the dominant modes of signal propagation. Meanwhile, in a high frequency scene, the penetration loss through the building is also greatly increased. Both of these factors can greatly increase the difficulty of signal coverage. By generating high-gain, adjustable shaped beams, signal coverage is significantly improved, and interference to the surroundings can be greatly reduced because the beams are very narrow.

Compared to conventional low frequency communication systems, terminal devices operating in higher frequency bands require beam management to ensure the quality of the communication link. With the advancement of mobile communication technology, diverse communication scenarios have emerged. However, when defining the beam management capability of the terminal device, the existing protocol does not consider the communication scenario in which the terminal device is located, so that the configuration of the beam management resource of the terminal device cannot be better adapted to the scenario in which the terminal device is located, and the flexibility is lacked.

To facilitate understanding, terms or concepts related to the embodiments of the present application are described below.

1. Beam (beam)

The representation of the beams in the NR protocol may be spatial filters, or so-called spatial filters or spatial parameters. A beam for transmitting a signal may be referred to as a transmission beam (Tx beam), may be referred to as a spatial domain transmit filter (spatial domain transmit filter), or a spatial transmit parameter (spatial domain transmit parameter); the beam used for receiving the signal may be referred to as a reception beam (Rx beam), may be referred to as a spatial domain receive filter (spatial domain receive filter), or a spatial domain receive parameter (spatial domain receive parameter).

The transmit beam may refer to a distribution of signal strengths formed in different spatial directions after the signal is transmitted through the antenna, and the receive beam may refer to a distribution of signal strengths of the wireless signal received from the antenna in different spatial directions.

It should be understood that the embodiment of the NR protocol listed above for the beams is only an example, and should not limit the present application in any way. This application does not exclude the possibility that other terms may be defined in future protocols to have the same or similar meaning.

Further, the beam may be a wide beam, or a narrow beam, or other type of beam. The technique of forming the beam may be a beamforming technique or other technique. The beamforming technology may specifically be a digital beamforming technology, an analog beamforming technology, or a hybrid digital/analog beamforming technology. Different beams may be considered different resources. The same information or different information may be transmitted through different beams.

The beam generally corresponds to the resource, for example, when the beam measurement is performed, the network device measures different beams through different resources, the terminal device feeds back the measured quality of the resource, and the network device knows the quality of the corresponding beam. In data transmission, the beam information is also indicated by its corresponding resource. For example, the network device indicates information of a Physical Downlink Shared Channel (PDSCH) beam of the terminal device through a Transmission Configuration Indicator (TCI) resource in Downlink Control Information (DCI).

Alternatively, a plurality of beams having the same or similar communication characteristics are regarded as one beam. One or more antenna ports may be included in a beam for transmitting data channels, control channels, sounding signals, and the like. The one or more antenna ports forming one beam may also be seen as one set of antenna ports.

In the embodiment of the present application, a beam refers to a transmission beam of a network device, unless otherwise specified. In beam measurement, each beam of the network device corresponds to one resource, so that the beam corresponding to the resource can be uniquely identified through the index of the resource.

The beams in the embodiment of the present application may be represented by a Transmission Configuration Indication (TCI) state, or may be represented by a quasi-co-location (QCL) relationship.

2. Quasi co-location (QCL)

Quasi-co-location (QCL) or quasi-co-location. The signals corresponding to the antenna ports having QCL relationship have the same parameters, or the parameters of one antenna port may be used to determine the parameters of another antenna port having QCL relationship with the antenna port, or two antenna ports have the same parameters, or the parameter difference between the two antenna ports is smaller than a certain threshold. Wherein the parameters may include one or more of: delay spread (delay spread), doppler spread (doppler spread), doppler shift (doppler shift), average delay (average delay), average gain, spatial Rx parameters. Wherein the spatial reception parameters may include one or more of: angle of arrival (AOA), average AOA, AOA extension, angle of departure (AOD), average angle of departure (AOD), AOD extension, receive antenna spatial correlation parameter, transmit beam, receive beam, and resource identification. In particular, the quasi-co-location may be used to indicate whether the csi reference signals transmitted by the at least two antenna ports are from the same transmission point or from the same beam group.

In the NR protocol, QCL relationships can be classified into the following four types (QCL-type) based on different parameters:

type a (type a): doppler frequency shift, doppler spread, average time delay and time delay spread;

type B (type B): doppler shift, doppler spread;

type C (type C): doppler shift, average time delay;

type D (type D): the space receives the parameters.

3. Transmission Configuration Indication (TCI)

In NR, beam indication corresponding to beam or reference signal transmission used by a downlink channel is implemented by associating a reference resource index in a transmission configuration indication TCI state table.

The network device configures a TCI state table (corresponding to TCI-states in 3GPP standard 38.331) through Radio Resource Control (RRC) high layer signaling, where each TCI state table includes a plurality of TCI states (corresponding to TCI-RS-Set in 3GPP standard 38.331). Each TCI state includes a TCI state ID (Transmission configuration indicator state ID), one or two quasi-co-located QCL type indicators (QCL-type a/B/C/D), and a reference signal index RS-ID corresponding to each type indicator.

After RRC configuration, the network device may activate one or more TCI-states through higher layer signaling (e.g., medium access control-control element (MAC-CE)). The activated TCI-state is a subset of the list of TCI-states configured by the RRC message. The network device may also indicate a selected TCI-state through a TCI field in physical layer signaling (e.g., downlink Control Information (DCI)). The DCI may be applied to, for example, DCI for scheduling physical downlink resources.

Wherein the configuration information of one TCI-state may include an identification of one or two reference signal resources and the associated QCL type. QCL characterizes some consistency relationship between the signal/channel currently to be received and some reference signal that is known before. If QCL relationships exist, the UE may inherit reception or transmission parameters when previously receiving some reference signal to receive or transmit an upcoming signal/channel. When the QCL relationship is configured to be one of type a, type B, or type C, the QCL relationship is used to indicate information such as time domain and frequency domain offset, and the terminal device may demodulate a Physical Downlink Control Channel (PDCCH) or a Physical Downlink Shared Channel (PDSCH) according to the indication of the TCI-state. When the QCL relationship is configured as type D, it may be considered as spatial QCL, and the terminal device may know which transmit beam is used by the network device to transmit signals, and may further determine which receive beam is used to receive signals according to the beam pairing relationship determined by the channel measurement as described above. The terminal device may determine a reception beam for receiving the PDSCH according to the TCI field in the DCI on the PDCCH.

4. Reference Signal (RS)

According to the protocol of long term evolution LTE/NR, in the physical layer, uplink communication includes transmission of an uplink physical channel and an uplink signal. Wherein the uplink physical channel: including a random access channel (PRACH), an uplink control channel (PUCCH), an uplink data channel (PUSCH), and the like, the uplink signal: the uplink positioning reference signal (SRS) is a Sounding Reference Signal (SRS), an uplink control channel demodulation reference signal (PUCCH-DMRS), an uplink data channel demodulation reference signal (PUSCH-DMRS), an uplink phase noise tracking reference signal (PTRS), an uplink positioning reference signal (uplink positioning RS), and the like.

The downlink communication includes transmission of a downlink physical channel and a downlink signal. The downlink physical channel comprises: a broadcast channel (PBCH), a downlink control channel (PDCCH), a downlink data channel (PDSCH), and the like, and the downlink signal includes: synchronization signal/physical broadcast channel block (SS/PBCH block, SSB), primary Synchronization Signal (PSS), secondary Synchronization Signal (SSs), downlink control channel demodulation reference signal (PDCCH-DMRS), downlink data channel demodulation reference signal (PDSCH-DMRS), downlink phase noise tracking reference signal (PTRS), channel state information reference signal (channel state information reference signal, CSI-RS), cell signal (CRS) (NR not), fine synchronization signal (e/frequency tracking reference signal, TRS) (LTE not), downlink positioning reference signal (downlink RS), reference signal (PL-RS) for measuring path loss, reference signal (PL-RS) for recovering radio beam reference signal (bfrs), and wireless reference signal (RS, RS) for detecting failure of radio beam reference signal (bfrs).

5. Beam management

The beam management comprises the steps of configuring beam management resources, measuring and selecting beams, reporting the beams and the like. The details are as follows.

(1) Configuring beam management resources

The beam management resource is a resource for measuring beam quality. Beam measurement, i.e. obtaining beam quality information by measuring a reference signal, the parameter for measuring the beam quality includes, but is not limited to, reference Signal Receiving Power (RSRP). For example, the beam quality may be measured by parameters such as Reference Signal Reception Quality (RSRQ), channel State Information (CSI), signal-to-noise ratio (SNR), signal-to-interference plus noise ratio (SINR), and block error rate (BLER). Wherein the CSI includes, but is not limited to, at least one of the following information: a Channel Quality Indicator (CQI), a Precoding Matrix Indicator (PMI), a Precoding Type Indicator (PTI), a Rank Indicator (RI), a CSI-RS resource indicator (CRI), and a Layer Indicator (LI).

The beam management resource includes reference signals for performing beam measurement, and the reference signals may be used for channel measurement or channel estimation, etc. The reference signal resource may be configured to configure transmission attributes of the reference signal, such as a time-frequency resource location, a port mapping relationship, a power factor, a scrambling code, and the like, the sending end device may send the reference signal based on the reference signal resource, and the receiving end device may receive the reference signal based on the reference signal resource.

The network device may configure the beam measurement report to the terminal device. The beam measurement report contains one or more of the following parameters: reporting configuration ID, reference signal resource time-frequency domain position for beam measurement, reporting configured time domain behavior (periodicity/semi-static/trigger type), reporting configured frequency domain behavior (sub-band/bandwidth and the like), reporting specific content and the like. The specific content may include any one or more of the following items: SINR, RSRP, CQI, PMI, RI, etc.

And the network equipment sends the beam measurement reference signal to the terminal equipment based on the beam measurement reporting configuration. The beam measurement reference signals may comprise any one or more of the various reference signals described above.

(2) Measuring and selecting beams, and reporting beams.

For example, the terminal device receives the reference signal at the corresponding time-frequency domain position based on the beam measurement reporting configuration.

The terminal device selects N (N is an integer greater than 1) transmission beams from transmission beams issued by the network device based on a specific criterion, and reports resource IDs (in 3GPP, the resource IDs may be CSI-RS resource index or SSB index) corresponding to the N beams and signal reception power to the network device.

The selection criterion of the beam reported by the terminal equipment can be specified by the network equipment or an internal implementation algorithm of the terminal equipment. For example, the terminal device may select the first few beams with the best beam quality from the configured resource set of the non-zero power CSI-RS for beam management for reporting.

The beam management mainly comprises the steps that the network equipment configures beam management resources, the network equipment sends beam management resource configuration information to the terminal equipment, the network equipment sends the beam management resources to the terminal equipment, the terminal equipment performs beam quality measurement according to the beam management resources, the terminal equipment reports the measured beam quality and the like.

When the network device configures the beam management resource for the terminal device, the network device determines the beam management resource according to the beam management capability information reported by the terminal device. However, the existing protocols do not define the beam management capability of the terminal device in different communication scenarios, specifically, the terminal device is in different scenarios, such as: the capabilities of scheduling with data information and scheduling without data information, scheduling with control information and scheduling without control information, and transmitting with reference signals and transmitting without reference signals are different, but the prior art does not consider this point, so that the beam management capability of the terminal device is too single, and further, when the network device configures the resources for beam measurement for the terminal device, the network device cannot be combined with the communication scenario where the terminal device is located, thereby resulting in poor flexibility of beam management of the terminal device.

The application provides a method and a device for beam management, which enable a network device to acquire first capability information of the terminal device in such a communication scene (i.e., no downlink data scheduling) by determining and reporting the first beam measurement capability information and/or the first reference signal measurement capability information when the terminal device does not have downlink data scheduling.

The method for beam management provided by the embodiment of the present application will be described below with reference to the accompanying drawings. It should be understood that the methods of beam management provided herein may be applicable to a wireless communication system, such as the wireless communication system 100 shown in fig. 1 or the wireless communication system 200 shown in fig. 2.

Fig. 4 is a method for beam management provided by the present application, which is illustrated from the perspective of device interaction and may be performed by the devices or systems in fig. 1 to 3.

S410, the terminal device determines first capability information, where the first capability information includes first beam measurement capability information and/or first reference signal measurement capability information, the first beam measurement capability information is used to indicate a number of beams that the terminal device can measure when there is no PDSCH scheduling on the physical downlink shared channel, and the first reference signal measurement capability information is used to indicate a number of reference signal resources that the terminal device can measure when there is no PDSCH scheduling on the physical downlink shared channel, and the reference signal measurement capability information is used to indicate a number of reference signal resources that the terminal device can measure when there is no PDSCH scheduling on the physical downlink shared channel.

The first beam measurement capability information is used to indicate the number of measurable beams by the terminal device in the absence of PDSCH scheduling, which may be understood as the number of handover beams by the terminal device in the absence of PDSCH scheduling. In one possible beam measurement method, the terminal device needs to adjust the spatial filter parameters of its antenna array so that the RSRP or RSRQ parameters of the received signal are maximized, in which case the number of measurable beams may be the maximum number of beams that the terminal device can switch when there is no PDSCH scheduling. In one possible beam measurement method, the terminal device may fix the reception beam and complete reception of signals transmitted by the base station through different downlink beams, in which case, the number of measurable beams may be the maximum number of downlink beams that the terminal device can receive without PDSCH scheduling.

The first reference signal measurement capability information is used to indicate the number of reference signal resources for beam management that the terminal device can measure without PDSCH scheduling, or it can be said that the terminal device supports without PDSCH scheduling. As an example, the reference signal resource for beam management may refer to a single or multiple port (port) CSI-RS resource or SSB resource, etc. The measurable amount of reference signal resources for beam management may refer to a measurable amount of at least one of the above resources by the terminal device when there is no PDSCH scheduling, e.g., to a maximum amount that can be measured by the terminal device for RSRP and/or SINR measurements on any one or more of the resources when there is no PDSCH scheduling. It should be understood that the terminal device may determine the measurement capability of multiple ports according to the measurement capability of a single port. For example, the measurement capability of the multi-port CSI-RS resource can be the sum of the measurement capabilities of the terminal device's multiple single-port CSI-RS resources. It should be noted that, in the present application, the number of reference signal resources used for beam management may also be understood as the number of reference signal resources used for beam measurement.

As an example, the first reference signal measurement capability information may include the number of reference signal resources for beam management that the terminal device can measure on all of its active serving cells (serving cells), component Carriers (CCs), and/or all of its active downlink bandwidth parts (BWPs) without downlink data scheduling.

As an example, the first reference signal measurement capability information may include the number of measurements of the aperiodic CSI-RS supported by the terminal device during a certain period of time when there is no downlink data scheduling.

It should be understood that, in the present application, the reference signals that may be used to measure the first beam measurement capability information and/or the first reference signal measurement capability information include, but are not limited to, at least one of: a synchronization signal/physical broadcast channel block SSB, a channel state information reference signal CSI-RS, a path loss reference signal PL-RS, a reference signal BFD-RS for beam failure recovery, a reference signal RLM-RS for radio link detection and a downlink reference signal PRS for positioning, a sounding reference signal SRS and a sounding reference signal posing SRS for positioning.

It should be understood that when the terminal device performs two or three parameter measurements simultaneously, the first beam measurement capability is not necessarily the sum of the first beam measurement capabilities when one of the parameter measurements is performed. For example, if the terminal device performs RSRP measurement, the number of switchable beams is 8, and if the terminal device performs CSI measurement, the number of switchable beams is 4. However, RSRP and CSI measurements are performed simultaneously, and the number of switchable beams is not necessarily 12. The same is true for the first reference signal measurement capability. Therefore, the first capability information reported by the terminal device may include a number of measurements of at least one of RSRP, RSRQ, CSI, SINR and SNR supported without PDSCH scheduling. The RSRP may be L1-RSRP, and the SINR may be L1-SINR.

In one possible implementation, the first capability information of the terminal device may also include a maximum number of TCI states supported without PDSCH scheduling. For example: the terminal device may measure the reference signal according to X TCI states, which include at least different QCL Type-D information, wherein the terminal device's capabilities may be the maximum number of X supported without PDSCH scheduling.

Optionally, the first capability information may also include a minimum number of measurements supported by the terminal device when there is no PDSCH scheduling.

It should be understood that the first capability information of the terminal device may include only the first beam measurement capability information, may also include only the first reference signal measurement capability information, and may also include both the first beam measurement capability information and the first reference signal measurement capability information.

It should be emphasized that the first capability information of the terminal device, including the first beam measurement capability information and/or the first reference signal measurement capability information, refers to capability information of the terminal device when there is no downlink data scheduling, or, in other words, refers to capability information of the terminal device when there is no Physical Downlink Shared Channel (PDSCH), where when there is no PDSCH scheduling, the terminal device may refer to the terminal device having no PDSCH scheduling, or refer to the terminal device not having PDSCH scheduling, nor having at least one of the following information: PUSCH, control information (e.g., PDCCH, PUCCH), downlink reference signals (e.g., SSB, CSI-RS, TRS), uplink reference signals (e.g., SRS), and so on. In other words, in the present application, there is no limitation on whether the terminal device has other information transmission besides the downlink data.

Optionally, the first capability information in this application may refer to a capability of the terminal device to have downlink control information (e.g., PDCCH) scheduling instead of downlink data (e.g., PDSCH) scheduling. It can also be said that the first capability information is a capability supported by the terminal device in a scenario where there is no downlink data scheduling but there is downlink control information scheduling.

Optionally, the first capability information in this application may refer to a capability of the terminal device in scheduling no downlink data (e.g., PDSCH) and no downlink control information (e.g., PDCCH). That is, the first capability information is a capability supported by the terminal device in a scenario where there is no downlink data scheduling and no downlink control information scheduling.

In a possible implementation manner, the terminal device does not perform transmission of uplink control information, uplink data, uplink signals, and any information unrelated to beam measurement when there is no downlink data scheduling, that is, the first capability information of the terminal device is a supported capability when the terminal device performs only beam measurement.

In a possible implementation manner, the terminal device may further determine second capability information when there is data scheduling, and similarly, the second capability information of the terminal device includes second beam measurement capability information and/or second reference signal measurement capability information, the second beam measurement capability information is used for indicating the number of beams measurable by the terminal device when there is PDSCH scheduling, and the second reference signal measurement capability information is used for indicating the number of reference signal resources for beam management measurable by the terminal device when there is PDSCH scheduling.

Alternatively, the second capability information may be capability information of the terminal device defined in 3GPP protocol TS 38.306.

Similarly, the second capability information of the terminal device may include capability information of the terminal device in a scenario where there is downlink data scheduling and there is downlink control information scheduling. That is, the second capability information is capability information of the terminal device when there is PDSCH and PDCCH scheduling.

Similarly, the second capability information of the terminal device may also include capability information of the terminal device in a scenario where there is downlink data scheduling and no downlink control information scheduling. That is, the second capability information is capability information of the terminal device when there is PDSCH without PDCCH scheduling

In the method and the device, the capability information of the terminal equipment in different scenes is defined, so that the beam management capability of the terminal equipment is diversified, the network equipment can configure diversified measurement resources for the terminal equipment according to the beam capability information of the terminal equipment in different scenes, and therefore the method and the device have stronger flexibility.

Optionally, the first/second capability information of the terminal device may refer to capability information of the terminal device for a preset time length. That is, the first/second capability information of the terminal device is for a continuous length of time. As an example, the preset time length may be indicated to the terminal device by the network device, or may be defined by a protocol, which is not limited in this application.

As an implementation manner, the preset time length is 1 time slot or N consecutive Orthogonal Frequency Division Multiplexing (OFDM) symbols, where N is an integer greater than 1. For example, the preset time duration is 2 continuous symbols, or 3 continuous symbols, or 4 continuous symbols, or a plurality of continuous symbols.

It should be noted that, in the present application, N consecutive symbols may refer to N symbols within one slot, or may also be N symbols consecutive in time across slots. For example, when one slot includes 14 symbols, the consecutive 5 symbols may be the 1 st to 5th symbols on the 1 st slot, or may be the 13 th to 14 th symbols on the 1 st slot and the 1 st to 3 rd symbols on the 2 nd slot.

As an implementation manner, the preset time length is T time slots, where T is a positive integer, for example, 2 time slots or 3 time slots.

It should be noted that, in the present application, a slot may be 14 symbols, for example, for an OFDM symbol with a normal cyclic prefix (normal cyclic prefix), a slot includes 14 symbols. One slot may also be 12 symbols, for example, for an extended cyclic prefix (extended cyclic prefix) OFDM symbol, one slot includes 12 symbols. Of course, this application does not exclude other values for the number of OFDM symbols included in a slot in future communication technologies.

Optionally, in this application, the first capability information of the terminal device includes that the terminal device does not have PDCCH scheduling of a physical downlink control channel for the preset time length. That is, the terminal device may not have downlink data information and downlink control information scheduling for the preset time length.

Optionally, the first/second capability information of the terminal device is capability information of the terminal device on M Component Carriers (CCs), where M is a positive integer. That is, the first/second capability information of the terminal device may be a measurement capability within 1 CC for M CCs, or may be a sum of measurement capabilities of a plurality of CCs, for example, 2 CCs, 3 CCs, or a plurality of CCs.

Optionally, the first/second capability information of the terminal device is capability information of the terminal device in L frequency ranges, where L is a positive integer. I.e. the first/second capability information of the terminal device may be for a single frequency range or for a plurality of frequency ranges, e.g. a sum of capability information for 2 frequency ranges or a sum of capabilities for 3 frequency ranges.

It should be understood that the Frequency Range (FR) can be FR1, i.e. a frequency band of 6GHz and below, or FR2, i.e. a frequency band of 6GHz to 71GHz, as defined in the standard. Of course, the frequency range may be other value ranges defined in future standards, or may be a customized frequency range, and the frequency range of the present invention is not limited to specific values.

It should be understood that the preset time length, the number of component carriers, the number of frequency ranges, and other parameters for which the first capability information and the second capability information are specific may be the same or different, and the present application is not limited thereto.

S420, the terminal device sends the first capability information to the network device, and the network device receives the first capability information.

When the first capability information of the terminal device includes the first beam measurement capability information or the first reference signal measurement capability information, the first capability information sent by the terminal device to the network device is the first beam measurement capability information or the first reference signal measurement capability information.

When the first capability information of the terminal device includes both the first beam measurement capability information and the first reference signal measurement capability information, the terminal device may transmit the two measurement capability information together in the first capability information to the network device as a whole. The terminal device may also report the determined first beam measurement capability information and the first reference signal measurement capability information to the network device as two pieces of information, respectively.

As an example, the first capability information transmitted by the terminal device to the network device may be included in PUCCH or PUSCH.

Optionally, if the terminal device determines the second capability information, the terminal device may further send the second capability information to the network device.

Optionally, the signaling carried by the first/second capability information reported by the terminal device to the network device may refer to a specification in 3GPP standard TS 38.331, which is not limited in this application.

S430, the network device determines a first resource to be measured according to the received first capability information, where the first resource to be measured is a resource to be measured when the terminal device does not have PDSCH scheduling.

That is, the network device may determine, according to the first capability information of the terminal device when there is no PDSCH scheduling, the first resource to be measured that the terminal device is more suitable for such a communication scenario. Generally, the capability of the terminal device without PDSCH scheduling is stronger than the capability of the terminal device with PDSCH scheduling, so that after the terminal device reports the first capability information, the network device may determine and configure a resource more suitable for a communication environment where the terminal device does not have downlink data scheduling, so that the terminal device can complete beam measurement in a shorter time.

As an example, the network device may determine the first resource to be measured in such a way that the first capability information and the first resource to be measured have a corresponding relationship, where the corresponding relationship may be pre-configured in the network device or defined by a protocol. Or, the network device may determine the first resource to be measured according to the current communication environment of the network device and the performance of the terminal device. The above embodiments are merely examples, and the present disclosure is not limited thereto.

Therefore, in the scheme of the application, the network device can acquire the capability of the terminal device when no downlink data is scheduled by determining and reporting the first capability information, and further, the network device can be configured according to the capability of the terminal device when configuring the beam management resource for the terminal device, so that the method and the system have stronger flexibility.

It should be understood that in the present application, the first resource to be measured may be one resource or may also be one resource set, i.e. a group of resources.

In one possible implementation manner, the first resource to be measured includes at least one of the following: number of ports, location of ports, time domain location and time domain duration, number of resources, number of resource sets, and period of resources.

That is, the first resource to be measured may include information of ports used for beam measurement, such as the number or number of ports, the location of ports, and time domain information of beam measurement, such as time domain start time or the location of time domain, time domain duration, and may further include the number of resources used for beam measurement, or the number of resource sets and the period of these resources.

Optionally, the method further comprises: s440, the network device sends first resource configuration information to the terminal device, where the first resource configuration information is used to indicate the first resource to be measured, so that the terminal device can perform beam measurement according to the first resource configuration information.

It should be understood that, in the present application, after determining the first resource to be measured, according to the information scheduling condition of the terminal device, when determining that the terminal device is in a scenario without downlink data scheduling, the network device may instruct, through the first indication information, the terminal device to use the first resource to be measured to perform beam measurement, where the first indication information may be included in the first resource configuration information, or may be sent separately from the first resource configuration information, or may be directly instructed through the first resource configuration information. In some cases, after determining the first resource to be measured, the network device may also send the first configuration information to the terminal device immediately, so that when the terminal device performs beam measurement, the terminal device may determine a suitable measurement resource according to the scene where the terminal device is located, the first resource to be measured, and other information.

Optionally, if the network device sends the first resource configuration information to the terminal device, the network device may also not schedule the terminal device in the configured time domain range, that is, does not send downlink data to the terminal device in the configured time domain range. Compared with the prior art, a network usually configures a large number of periodic reference signals for beam measurement, and the reference signals are dispersedly located on time domain resources for scheduling or other implementation considerations, so that a high-frequency terminal is difficult to sleep for a long time. Therefore, according to the scheme of the application, the first resource to be measured of the terminal equipment without downlink data scheduling is configured, so that the terminal equipment can perform concentrated beam measurement without downlink data scheduling, the terminal equipment is prevented from being awakened discontinuously, and the power consumption of the terminal equipment is reduced.

As a possible implementation manner, after the terminal device reports the first capability information, the network device may send the first resource configuration information to the terminal device. Furthermore, because the terminal device has stronger capability at this stage and the beam measurement resource is matched with the capability of the terminal device, the beam measurement can be intensively completed in shorter wake-up time, and the terminal device can continue to sleep after the beam measurement is completed. By the method, the condition that the terminal equipment can complete beam measurement only by needing longer wake-up time due to lower matching degree of measurement resources and measurement capacity is avoided, namely, the method can reduce the wake-up time of the terminal equipment in a high-frequency communication system, further reduce power consumption and improve user experience.

Optionally, the first resource configuration information may include reporting configuration information, where the reporting configuration information is used to indicate a reporting parameter of the terminal device, that is, the network device may configure the reporting parameter to the terminal device, and indicate how to report the terminal device, and the terminal device performs beam measurement according to the first resource to be measured and then reports the measured beam according to the reporting parameter. For example, the reporting parameter may include a reported time domain position and/or frequency domain position, and a specific reported content, such as one or more of RSRP, CQI, SINR, PMI, RI, and the like.

Optionally, the method further includes: s450, the terminal device performs beam measurement according to the first resource allocation information.

When the network device configures the first resource to be measured when no data is scheduled for the terminal device, the terminal device may select a suitable resource for beam measurement according to the first resource to be measured and its own communication environment. Specifically, the following cases may be included: and the terminal equipment uses the first resource to be measured to perform beam measurement under the condition of no PDSCH scheduling. Or, the terminal device performs beam measurement by using the second resource to be measured when the PDSCH scheduling exists, where the second resource to be measured is the resource to be measured when the PDSCH scheduling exists. Both of these modes are described below with reference to fig. 5 and 6.

Fig. 5 is another schematic diagram of a method for beam management according to an embodiment of the present application. In fig. 5, the network device configures a CSI-RS measurement resource (an example of a first resource to be measured) without data scheduling in a time slot to the terminal device, and the CSI-RS measurement resource occupies the 7 th to 12 th symbols in the time domain. The terminal device has no data scheduling in the time slot, so the terminal device can measure the CSI-RS resources of the 7 th to 12 th symbols according to the communication environment of the terminal device and the configuration of the network device.

Fig. 6 is a schematic diagram of a method for beam management according to an embodiment of the present application. In fig. 6, the network device configures, to the terminal device, a CSI-RS measurement resource (an example of a first resource to be measured) without data scheduling in a time slot, which occupies the 7 th to 12 th symbols in the time domain. However, the terminal device has data scheduling in the 1 st to 5th symbols of the slot, and therefore, the terminal device can measure only the CSI-RS resources of the 9 th to 12 th symbols according to its own communication environment (i.e., whether there is downlink data transmission) and the configuration of the network device. Among them, the CSI-RS resource of the 9 th to 12 th symbols is an example of the second resource to be measured.

Optionally, taking fig. 6 as an example, the terminal device does not schedule data in the 7 th to 12 th symbols, which may be that the network device instructs the terminal device not to schedule data in the time domain.

The second resource to be measured may be configured to the terminal device by the network device. For example, in one possible implementation, the method further includes: s460, the network device determines a second resource to be measured. S470, the network device sends second resource allocation information, where the second resource allocation information is used to indicate the second resource to be measured.

Specifically, if the terminal device sends the second capability information to the network device, the network device may determine the second resource to be measured according to the second capability information of the terminal device, where the second resource to be measured is a resource to be measured when the terminal device has PDSCH scheduling. It should be understood that, if the terminal device does not send the second capability information to the network device, the network device may also configure, with reference to the first capability information of the terminal device, a second resource to be measured that is not greater than the first resource to be measured for the terminal device, that is, the second resource to be measured is a subset of the first resource to be measured. The network device may also determine the second resource to be measured with reference to the capability information reported by the previous terminal device without distinguishing scenes, which is not limited in the present application.

Similarly, after determining the second resource to be measured, the network device may instruct, according to the information scheduling condition of the terminal device, the terminal device to use the second resource to be measured to perform beam measurement when determining that the terminal device is in a scene with downlink data scheduling, where the second instruction information may be included in the second resource configuration information, may also be sent separately from the second resource configuration information, or may directly instruct by the second resource configuration information. In some cases, after determining the second resource to be measured, the network device may also immediately send the second configuration information to the terminal device, so that when the terminal device performs beam measurement, the terminal device may determine an appropriate measurement resource according to the scene where the terminal device is located, the second resource to be measured, and other information.

Optionally, the second resource to be measured may also be preconfigured in the terminal device.

Optionally, the second resource to be measured may also be a partial resource selected by the terminal device from the first resource to be measured configured by the network device, that is, the network device does not need to configure the second resource to be measured to the terminal device, and the terminal device determines the second resource to be measured according to the first resource to be measured, for example, the terminal device determines that a partial resource in the first resource to be measured is the second resource to be measured.

Similarly, the second resource to be measured includes at least one of: number of ports, location of ports, time domain location and time domain duration, number of resources, number of resource sets, and period of resources.

That is, the second resource to be measured may include information of ports for beam measurement, such as the number or number of ports, the location of ports, and time domain information of beam measurement, such as time domain start time or location of time domain, time domain duration, and may further include the number of resources for beam measurement, or the number of resource sets and the period of these resources.

Optionally, the second resource configuration information may also include reporting configuration information, where the reporting configuration information is used to indicate a reporting parameter of the terminal device, that is, the network device may configure the reporting parameter to the terminal device, and indicate how to report the terminal device, and the terminal device performs beam measurement according to the second resource to be measured and then reports the second resource according to the reporting parameter. For example, the reporting parameter may include a time domain position and/or a frequency domain position that is reported, and specific content that is reported, for example, one or more of RSRP, CQI, SINR, PMI, RI, and the like.

Therefore, the method and the device for measuring the beam of the terminal equipment enable the terminal equipment to be flexibly selected according to the scene where the terminal equipment is located by configuring various measurement resources for the terminal equipment, and therefore flexibility of beam management of the terminal equipment is improved.

Optionally, in the present application, the method may further include: and after the terminal equipment finishes the beam measurement, reporting a beam measurement result. Specifically, the terminal device may report according to reporting configuration information in the first resource configuration information or the second resource configuration information. Or, the terminal device may report according to reporting configuration information preconfigured locally or specified by a protocol.

Optionally, the reporting configuration information may also be sent separately from the first/second resource configuration information, which is not limited in this application.

Optionally, in this application, if the first resource to be measured and the second resource to be measured are configured to perform measurement reporting aperiodically, the network device may further send indication information to the terminal device, so as to indicate a reporting timing of the terminal device. For example, the indication may be indicated by Downlink Control Information (DCI).

Optionally, in this application, if the first resource to be measured and the second resource to be measured are configured to be measured and reported semi-persistently (semi-persistent), the network device may further send indication information to the terminal device, indicating a reporting timing of the terminal device. For example, it may be indicated by activating a signaling medium access control element (MAC-CE).

In a possible implementation manner, the method further includes: s480, the terminal device may receive a request message sent by the network device, where the request message is used to request the terminal device to send the first capability information and/or the second capability information. That is, before S410, the terminal device may send the first capability information and/or the second capability information to the network device according to a request of the network device. It should be understood that the request message for requesting the first capability information and the request message for requesting the second capability information may be the same or different, and the application is not limited thereto.

As a possible implementation manner, the first resource to be measured may be a centralized SSB resource, which includes multiple SSBs that are consecutive in a time domain, that is, the centralized SSB resource has no Orthogonal Frequency Division Multiplexing (OFDM) symbol interval in the time domain. Wherein each SSB occupies Y OFDM symbols, and Y is a positive integer.

Fig. 7 is a schematic diagram of a centralized SSB resource provided in an embodiment of the present application. Wherein, referring to the definition of the existing protocol, one SSB occupies 4 symbols in the time domain, and each SSB in the figure represents a signal transmitted through a different beam. The network device may configure a centralized SSB resource to the terminal device according to the first capability information of the terminal device, and then send a plurality of SSBs, where the plurality of SSBs are consecutive in a time domain and used for the terminal device to perform beam measurement.

It should be understood that the centralized SSB resource in fig. 7 is only for illustration, and each of the SSBs included in the centralized SSB resource in this application may occupy 1, 2, 3, or 5 symbols, or occupy other numbers of symbols, which is not limited in this application. Optionally, in this case, each of the plurality of SSBs included in the centralized SSB resource may include a primary synchronization signal PSS and/or a secondary synchronization signal SSS.

Optionally, the first indication information sent by the network device to the terminal device may also be used to indicate a time domain starting position where the centralized SSB resource is located, for example, the time domain starting position may be an offset value relative to a starting position of a system frame, or an offset symbol number of a certain timeslot in a system frame.

Optionally, the first indication information sent by the network device to the terminal device may also be used to indicate a period of the centralized SSB resource.

Optionally, the first indication information sent by the network device to the terminal device may also be used to indicate whether the terminal device needs to receive the centralized SSB resource outside an awake period (On-Duration) of a Discontinuous Reception (DRX) mode.

In a possible implementation manner, the first indication information sent by the network device to the terminal device may also be used to instruct the terminal device not to perform other information processing during beam measurement (i.e., beam measurement without interruption in the time domain). For example, data reception and demodulation are not performed, data transmission is not performed, or the terminal device does not need to wake up to receive the SSB signal which is discontinuous in the time domain, and further, it is not necessary to measure such a SSB signal which is discontinuous in the time domain.

It will be appreciated that at times other than those described above (i.e. uninterrupted beam measurements in the time domain), the terminal device may make beam measurements according to existing protocols.

In the prior art, the SSB used for beam measurement usually lasts for a long time (e.g., 5 ms) and has a short period (e.g., 20 ms), so that the terminal device needs to wake up continuously to measure the SSB. In contrast, the terminal device can perform centralized beam measurement when no data is scheduled through the centralized SSB resource, so that the terminal device is prevented from being awakened and dormant continuously due to beam measurement, power consumption of the terminal device is reduced, and user experience is improved.

It should be understood that the content indicated by the first indication information may be sent in one indication information, or may be explicitly or implicitly indicated in different information, respectively, and the present application is not limited thereto.

In one possible implementation, the network device may send, to the terminal device, first configuration information indicating centralized synchronization signal/physical broadcast channel block SSB resources, where the centralized SSB resources include a plurality of SSBs consecutive in a time domain, and each of the plurality of SSBs occupies Y orthogonal frequency division multiplexing OFDM symbols, and Y is a positive integer. Correspondingly, the terminal device may receive the first configuration information and then perform beam measurement according to the first configuration information.
