[0076] I. Beam sweeping

[0077] Beam sweeping is a technique of forming beams by antennas, which can focus radio frequency energy to a specific direction, thereby increasing the transmission range and speed of signals. Beam sweeping enables network devices and terminal devices to obtain and maintain a set of beams for transmission and reception, and then realize high-gain communication with reasonable beams. As shown in FIGS. 2A-2C, beam sweeping can be divided into three stages (P-1, P-2 and P-3), and the operations of each stage are summarized as follows:

[0078] P-1 stage: Initial gNB Beam Acquisition stage: the terminal device measures different beams transmitted by the network device to support the selection of the transmission beam of the network device and the reception beam of the terminal device;

[0079] P-2 stage: gNB Beam Refinement stage: the network device adjusts the transmission beam to concentrate the transmission beam in the direction of the terminal device. In this step, the network device transmits narrower and denser beams than in the P-1 stage, which is used for beam refinement;

[0080] P-3 stage: UE Beam Refinement stage: the terminal device measures the beams transmitted by the same network device to improve the reception beam of the terminal device.

[0081] II. Layer 1 (L1) measurement

[0082] Layer 1 (L1) measurement

[0083] L1 refers to the physical layer (Physical Layer, PHY). Illustratively, the types of L1 measurement include at least one of the following:

[0084] Radio Link Monitoring (RLM);

[0085] Candidate Beam Detection (CBD);

[0086] Beam Failure Detection (BFD);

[0087] Layer 1 Reference Signal Received Power (L1-RSRP);

[0088] Layer 1 Signal-to-Interference-and-Noise Ratio (L1-SINR).

[0089] The L1 measurement can be based on Synchronization Signal and PECH Block (SSB) or Channel-Slate Information Reference Symbol (CSI-RS) resource.

[0090] Three, Layer 3 (L3) measurement

[0091] L3 refers to the Radio Resource Control (RRC) layer. The L3 measurement is mainly used for mobility management. The L3 measurement can be divided into SSB-based and CSI-RS-based measurement according to the type of reference signal.

[0092] Four, Faster Beam Sweep (FBS / BSF):

[0093] In the related art, the L1 faster beam sweep based on multi-Rx operation is defined, and it is discussed that under which scenarios or conditions the UE can accelerate the beam sweep to shorten the L1 measurement time. There are many differences between the L3 measurement and the L1 measurement. Under which conditions / circumstances / modes / UE states, the accelerated beam sweep can be used to shorten the L3 measurement time and reduce the L3 measurement delay, which is a technical problem to be solved.

[0094] FIG. 3 is a schematic flowchart of a method 300 for implementing faster beam sweep according to an embodiment of the present application. The method can optionally be applied to the system shown in FIG. 1 or FIG. 2, but is not limited thereto. The method includes at least part of the following content.

[0095] S310, the terminal device enters the faster beam sweep state of the L3 measurement when the criterion of the faster beam sweep is met; the criterion of the faster beam sweep includes at least one of the following:

[0096] The terminal device has low mobility;

[0097] The terminal device is not at a cell edge;

[0098] The terminal device supports multi-receive operation;

[0099] The terminal device is configured to report a group-based beam report.

[0100] The method proposed by the embodiments of the present application can make the terminal device switch into the fast beam scanning state of L3 measurement in the case that the terminal device meets the criterion of fast beam scanning, thereby shortening the L3 measurement time.

[0101] The criterion of fast beam scanning can also be referred to as a condition / case / scene / mode of fast beam scanning, and the following is collectively referred to as the criterion of fast beam scanning.

[0102] In some embodiments, the terminal device supports multi-receive operation (multi-Rx operation), including at least one of the following:

[0103] The terminal device selects a pair of beam pairs through group resources configured by the network device, and reports the measurement result of the beam pair;

[0104] The terminal device sends the network device a tendency to work in a multi-panel (multi-panels) active state.

[0105] For example, the terminal device sends the network device a tendency to work in a multi-panel (multi-panels) active state through a user equipment assistance information (UE Assistance Information, UAI), indicating that the terminal device itself hopes to work in a multi-panels active state.

[0106] In some embodiments, the terminal device is configured to report a group-based beam report (Group Based Beam Reporting, GBBR), including that the network device configures group resources to the terminal device and instructs the terminal device to report a beam report based on the configuration; or including that the network device configures group resources to the terminal device and instructs the terminal device to report a beam report based on the configuration, and the terminal device replies to the network device an acknowledgement message.

[0107] In addition to the above, the criterion of fast beam scanning can also include at least one of the following:

[0108] L3 measurement is relevant to multi-TRP operation deployment (Rel-19 L3 measurement with multi-Rx DL reception is relevant to multi-TRP operation deployment);

[0109] Two panels activated, two searchers are occupied by this single carrier (RRM measurement with two panels activated, two searchers are occupied by this single carrier);

[0110] SSB processing delay / time for processing multiple beams received in a SMTC (SS / PBCH block measurement timing configuration, SMTC) (SSB processing delay / time for processing multiple beams received in a SMTC);

[0111] UE has prior knowledge on the cell to be measured (UE has prior knowledge on the cell to be measured);

[0112] Simultaneous operation between multi-Rx simultaneous reception (L1) and L3 measurement delay reduction by optimizing Rx BSF (Simultaneous operation between multi-Rx simultaneous reception (L1) and L3 measurement delay reduction by optimizing Rx BSF).

[0113] In some embodiments, the terminal device can report to the network device at least one of the following:

[0114] Fast beam scanning capability;

[0115] Capability of supporting network configuration triggering criteria;

[0116] Capability of supporting autonomous judgment criteria.

[0117] For example, the fast beam scanning capability can be per UE or per band.

[0118] For example, the capability of supporting the network configuration triggering criterion, which can also be referred to as the tendency of supporting the network configuration triggering criterion, can refer to the capability of the terminal device that supports the network device triggering the terminal device to enter the fast beam scanning state for L3 measurement.

[0119] For example, the capability of supporting the autonomous judgment criterion, which can also be referred to as the tendency of supporting the autonomous judgment criterion, can refer to the capability of the terminal device that determines whether the terminal device itself meets the criterion of the fast beam scanning state and enters the fast beam scanning state for L3 measurement when the criterion is met.

[0120] The terminal device can report the capability of fast beam scanning and the capability of supporting the network configuration triggering criterion, or report the capability of fast beam scanning and the capability of supporting the autonomous judgment criterion, or report the capability of fast beam scanning, the capability of supporting the network configuration triggering criterion, and the capability of supporting the autonomous judgment criterion when reporting the capability to the network device.

[0121] The terminal device reports the capability in one of the above manners, and based on the capability, the network device can trigger the terminal device to enter the fast beam scanning state, or the terminal device can autonomously switch to enter the fast beam scanning state.

[0122] In some embodiments, the terminal device can receive the criterion for fast beam scanning from the network device.

[0123] There are at least the following cases for whether the terminal device reports the capability of supporting the network configuration triggering criterion and the capability of supporting the autonomous judgment criterion to the network device, and whether the terminal device receives the criterion for fast beam scanning from the network device.

[0124] In a first case, when the terminal device reports the capability of supporting the network configuration triggering criterion to the network device, and the terminal device receives the criterion for fast beam scanning from the network device, the terminal device reports the measurement result to the network device, and enters the fast beam scanning state for L3 measurement based on the confirmation information received from the network device. In this case, the terminal device can also report the capability of fast beam scanning and / or the capability of supporting the autonomous judgment criterion to the network device.

[0125] The confirmation information can be sent through a downlink control information (DCI) or a medium access control-control element (MAC-CE), etc., and is used to trigger the UE to change the speed of beam scanning and enter the fast beam scanning state.

[0126] In an example, the terminal device can determine whether the measurement result satisfies the criterion of the fast beam sweeping state based on the received criterion, and if so, report the measurement result to the network device. In another example, the terminal device can directly report the measurement result to the network device (without determination), and the network device determines whether the measurement result satisfies the criterion of the fast beam sweeping state.

[0127] Case two: in the case where the terminal device reports the capability of supporting the network configuration triggering criterion to the network device (but does not report the capability of supporting the autonomous determination criterion), and the terminal device does not receive the criterion of the fast beam sweeping, the terminal device does not enter the fast beam sweeping state of L3 measurement.

[0128] In this case, the terminal device can also report the capability of fast beam sweeping to the network device, but does not report the capability of supporting the autonomous determination criterion.

[0129] Case three: in the case where the terminal device reports the capability of supporting the autonomous determination criterion to the network device (but does not report the capability of supporting the network configuration triggering criterion), the terminal device determines whether the criterion of the fast beam sweeping defined by the protocol is satisfied, and if so, enters the fast beam sweeping state of L3 measurement.

[0130] In this case, the terminal device can also report the capability of fast beam sweeping to the network device, but does not report the capability of supporting the network configuration triggering criterion.

[0131] Case four: in the case where the terminal device reports the capability of supporting the network configuration triggering criterion and the capability of supporting the autonomous determination criterion to the network device, and the terminal device receives the criterion of the fast beam sweeping from the network device, the terminal device reports the measurement result to the network device, and enters the fast beam sweeping state of L3 measurement based on the confirmation information received from the network device. The confirmation information can be sent through downlink control information (DCI) or medium access control-control element (MAC-CE), etc., for triggering the UE to change the beam sweeping speed and enter the fast beam sweeping state.

[0132] In this case, the terminal device can also report the capability of fast beam sweeping to the network device.

[0133] Similar to case one, in an example, the terminal device can determine whether the measurement result satisfies the criterion of the received fast beam sweeping state based on the criterion, and if so, report the measurement result to the network device. In another example, the terminal device can directly report the measurement result to the network device (without determination), and the network device determines whether the measurement result satisfies the criterion of the fast beam sweeping state.

[0134] Case five: in the case where the terminal device reports to the network device the capability of supporting the network configuration triggering criterion and the capability of supporting the autonomous determination criterion, and the terminal device does not receive the criterion of the fast beam sweeping, the terminal device determines whether the criterion of the fast beam sweeping defined by the protocol is satisfied, and if so, enters the fast beam sweeping state of L3 measurement.

[0135] In some embodiments, the terminal device can directly enter the fast beam sweeping state triggered by the network device or autonomously enter the fast beam sweeping state without considering the prerequisites in the above cases one to five. For example:

[0136] In an example, the terminal device enters the fast beam sweeping state of L3 measurement when the criterion of the fast beam sweeping is satisfied, including:

[0137] The terminal device reports the measurement result to the network device and enters the fast beam sweeping state of L3 measurement based on the confirmation information received from the network device.

[0138] In another example, the terminal device enters the fast beam sweeping state of L3 measurement when the criterion of the fast beam sweeping is satisfied, including:

[0139] The terminal device determines whether the criterion of the fast beam sweeping defined by the protocol is satisfied, and if so, enters the fast beam sweeping state of L3 measurement.

[0140] In some implementations, the criterion of the fast beam sweeping corresponds to different sets of terminal devices.

[0141] In some implementations, the terminal device enters the fast beam sweeping state of L3 measurement, including: the terminal device determines the corresponding scanning factor based on the fast beam sweeping capability; the terminal device determines the time requirement of the fast scanning based on the scanning factor, and performs the fast scanning according to the time requirement.

[0142] In some implementations, the UE or network device determines whether the criterion of the fast beam sweeping is satisfied in at least the following ways:

[0143] (1) Network configures UE to perform L1 or L3 measurement, and the measurement result and / or UE's moving speed, etc. meet the low mobility condition, then the UE autonomously or the base station determines that the UE meets the criterion of the fast beam sweeping;

[0144] (2) Network configures UE to perform L1 or L3 measurement, and the measurement result (such as SSB-RSRP or CSI-RS-RSRP, SINR, etc. greater than a threshold) meets the condition that the UE is not at the cell edge, then the UE autonomously or the base station determines (the UE needs to report these measurement results to the base station) that the UE meets the criterion of the fast beam sweeping;

[0145] (3) Network configures UE to perform L1 or L3 measurement, UE completes beam pair search, and successfully reports L1 or L3 measurement report on the group resources of the beam pair, then the base station determines that the UE meets the criterion of the fast beam sweeping state;

[0146] (4) Network configures UE to perform Group Based Beam Reporting (GBBR), and the UE reports UAI indicating that it expects to work in the multi-Rx panel activation state, then the base station determines that the UE meets the criterion of the fast beam sweeping state.

[0147] Embodiment one:

[0148] In this embodiment, the network configures to trigger the UE fast beam sweeping under single or multiple criteria.

[0149] FIG. 4 is an implementation flowchart of the embodiment one of the present application, including the following steps:

[0150] S401, the UE supporting fast beam sweeping reports capability to the base station in the connected state, which can be per UE or per band; at the same time, the UE reports the capability or tendency of "supporting network configuration triggering criterion" to the network.

[0151] S402, the base station configures the criterion of the fast beam sweeping state for the UE reporting the support of the fast beam sweeping, for example, the criterion is for FR2 28GHz band, the criterion includes that the UE meets the low mobility and multi-receiving operation at the same time; the base station also configures the UE to feed back the state when the criterion of the fast beam sweeping state is met.

[0152] For example, low mobility is satisfied, i.e., the speed is lower than 30km / h.

[0153] For example, multi-Rx operation is satisfied, i.e., the UE reports measurement results on a pair of beam pairs selected from group resources configured by the network to complete group based beam reporting, and / or confirms that it wants to work in a multi-panel activated state through a UAI.

[0154] S403, the UE reports measurement results and / or a tendency to work in a multi-panel activated state to the base station, and the base station confirms that the current UE can enter a fast beam scanning state according to the received information and sends confirmation information to the UE. Before the base station confirms, the UE reports the capability of fast beam scanning, for example, the scanning factor is N=4. When the UE reports measurement results to the base station, the measurement results that meet the criteria of the fast beam scanning state can be reported; or the UE can directly report the measurement results to the base station, and the base station determines whether the measurement results meet the criteria of the fast beam scanning state, and sends confirmation information to the UE in the case of meeting.

[0155] S404, the UE receives the confirmation information and enters the fast beam scanning state of L3 measurement.

[0156] S405, the UE measures according to the time requirement of the measurement after fast scanning. For example, the period of completing one RRM L3 measurement of the UE becomes half of the original, N=8 becomes N=4: the UE reports measurement results according to the measurement reporting requirement.

[0157] Embodiment two:

[0158] In this embodiment, based on UE autonomous judgment, the UE that meets the criteria of the fast beam scanning state autonomously enters the fast beam scanning state.

[0159] FIG. 5 is an implementation flowchart of embodiment two of the present application, including the following steps:

[0160] S501, the UE supporting fast beam scanning reports the capability to the base station in the connected state, which can be per UE or per band; at the same time, the UE reports the capability or tendency of “supporting autonomous judgment criteria” to the network.

[0161] S502, the UE judges whether the criterion of the fast beam sweeping state is met, for example, the criterion of the fast beam sweeping state includes: the UE meets the low mobility (such as the speed is lower than 30km / h), and the UE has reported the measurement result of the beam pair in a recent period of time (such as 1 minute).

[0162] The two criteria can be the criteria predefined in the protocol, which can correspond to different sets, and the UE meets different sets, which correspond to different scanning factors N under different fast scanning capabilities.

[0163] The UE judges based on the measurement result, for example,

[0164] (1) The UE judges whether the UE itself meets the low mobility (whether the speed is lower than 30km / h):

[0165] (2) The UE judges whether the UE has reported the report through a pair of beam pairs selected from the group resources configured by the network in a period of time (such as 1 minute) before meeting other conditions.

[0166] If the above judgments are all met, the UE can enter the fast beam sweeping state, that is, step S403 is executed.

[0167] S503, the UE switches into the fast beam sweeping state, and selects the scanning factor corresponding to the group criterion condition met in the fast beam sweeping capability reported before, such as N=4.

[0168] S504, the UE measures according to the time requirement of the measurement after the fast scanning. For example, the period of the UE completing a measurement becomes half of the original, N=8 becomes N=4; the UE reports the measurement result according to the measurement reporting requirement.

[0169] Embodiment three:

[0170] In this embodiment, the UE has both the capability of supporting the network configuration triggering criterion and the capability of supporting the autonomous judgment criterion.

[0171] FIG. 6 is an implementation flowchart of embodiment three of the application, including the following steps:

[0172] S601, the UE supporting the fast beam sweeping reports the capability to the base station in the connected state, which can be per UE or per band: at the same time, the UE reports the capability or tendency of “supporting the network configuration triggering criterion” and the capability or tendency of “supporting the autonomous judgment criterion” to the network.

[0173] If the current network configures the UE with the criterion of the fast beam sweeping state, the UE performs in the manner of Embodiment 1, that is, performs S410-S404 described above; then performs the fast sweeping, that is, performs step S602.

[0174] If the current network does not configure the UE with the criterion of the fast beam sweeping state, the network performs in the manner of Embodiment 2, that is, performs S502-S503 described above; then performs the fast sweeping, that is, performs step S602.

[0175] S602, the UE measures according to the time requirement of the measurement after the fast sweeping. For example, the period of one measurement of the UE becomes half of the original, N=8 becomes N=4; the UE reports the measurement result according to the measurement reporting requirement.

[0176] In summary, the method for implementing the fast beam sweeping proposed in the embodiments of the present application can make the UE enter the fast sweeping state of the L3 measurement in the case of meeting the criterion of the fast beam sweeping state, so that the UE can shorten the RRM L3 measurement time by accelerating the beam sweeping, and when the network configures more TRPs, the UE can also obtain higher data rate and throughput through the fast beam sweeping. Moreover, the method proposed in the embodiments of the present application can make the terminal device enter the fast beam sweeping state triggered by the network device or enter the fast beam sweeping state autonomously according to the capability reported by the terminal device.
