Description

Beam management method and device Technical Field

[0001] The embodiments of the present application relate to the field of communication technologies. Background Art

[0002] High-band millimeter wave communication is one of the key technical directions of 5G NR (fifth-generation new wireless). Compared to low-band communications, such as those in the sub-6 GHz band, high-band communications face challenges such as high transmission path loss and susceptibility to obstruction. To overcome these challenges, the transmitter uses a large number of densely distributed antenna units and uses beamforming to form beams pointing in specific directions to improve coverage. Correspondingly, the receiver uses beamforming to receive beams in specific directions. This requires the transmitter to select an appropriate transmit beam and the receiver to select an appropriate receive beam to form a beam pair, which together maintain a good wireless link. Beam Management (BM) can establish and maintain such beam pairs.

[0003] In the beam management process of traditional communication systems (3GPP Rel-15 to Rel-18, Releases 15 to 18 of the Third Generation Partnership Project), network devices configure or activate frequent periodic or semi-continuous beam reporting, or trigger frequent non-periodic beam reporting, in order to obtain beam information related to data transmission in a timely manner. However, this method results in large control signaling overhead and reporting overhead. However, if the configured beam reporting frequency is low, the beam information reported by the terminal device may be outdated, and the network device may not always obtain the "best / preferred" beam, resulting in degraded system performance.

[0004] In traditional communication systems (3GPP Rel-15 to Rel-18), beam management is primarily initiated by network devices. These devices configure reference signals (RS) for beam management for terminal devices. The terminal devices then report their measurement results. Based on these measurements, the network device decides whether to initiate beam management and sends relevant signaling. The network device then performs the corresponding beam management operations based on the signaling. However, this type of beam management suffers from high signaling overhead, long latency, and significant limitations on flexibility.

[0005] It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solutions of this application and for the convenience of understanding by those skilled in the art. It cannot be considered that the above technical solutions are well known to those skilled in the art simply because these solutions are explained in the background technology part of this application.

[0006] Summary of the Invention

[0007] The inventors found that in 3GPP Rel-19, UE-initiated or event-driven beam management (hereinafter referred to as UE-initiated beam management, UEI BM) initiated by UE (called user equipment, terminal equipment, terminal, user, etc.) has been identified as one of the project contents. Since the UE can obtain better and more timely beam information, in the UE-initiated beam management, the UE can monitor the downlink beam quality. When an event related to beam management is detected, it can actively initiate a beam management (such as beam switching) request to the network device. In this way, the beam reporting can be performed more timely while reducing the reporting overhead, and the delay of beam management can be effectively reduced, the signaling overhead can be reduced, and the network coverage can be improved.

[0008] For beam management initiated by UE, the embodiments of the present application provide a beam management method and device to reduce the delay of beam management, reduce signaling overhead, and improve network coverage.

[0009] According to one aspect of an embodiment of the present application, a beam management apparatus is provided, configured in a terminal device, the apparatus comprising:

[0012] The second sending unit is configured to send the first information at a first reporting opportunity after sending all of the at least one first SR.

[0013] According to another aspect of an embodiment of the present application, a beam management apparatus is provided, configured in a terminal device, the apparatus comprising:

[0014] a receiving unit configured to receive a CSI reporting configuration, wherein the CSI reporting configuration includes at least one CSI-ReportConfig related to UEI BM reporting, and the CSI-ReportConfig is associated with at least one first SR;

[0015] a first sending unit, configured to send the at least one first SR after detecting a UEI BM event;

[0016] The second sending unit sends the first information at the first reporting opportunity after the receiving unit receives the second information, where the second information is a confirmation that the first SR is successfully received by the network device.

[0017] One of the beneficial effects of the embodiments of the present application is that: according to the embodiments of the present application, in the UEI BM process, for the scenario of using the first SR and pre-configured resources to report the UEI BM, the terminal device sends multiple first SRs after detecting the UEI BM event, and then sends the first information at the first reporting opportunity; or the terminal device sends the first SR and then sends the first information at the first reporting opportunity after receiving the confirmation information (second information), which can improve the reliability of the terminal device sending the first SR, and can reduce or eliminate the possibility of the first information sent by the terminal device conflicting with other information scheduled by the network device.

Unless otherwise specified herein, "device" can refer to either network equipment or terminal equipment.

[0052] To facilitate understanding, some concepts involved in the embodiments of this application are explained below.

[0053] In the embodiment of the present application, uplink control information (UCI) mainly includes hybrid automatic repeat request acknowledgment (HARQ-ACK), scheduling request (SR), channel state information (CSI), etc. Uplink control information can be transmitted on the physical uplink control channel (PUCCH) or the physical downlink shared channel (PUSCH).

[0054] SR is a type of UCI, sent by the UE to the gNB via the PUCCH to request uplink resources from the network. The RRC (Radio Resource Control) pre-configures dedicated periodic PUCCH resources, which the UE uses to send SR on the PUCCH.

[0055] CSI is also a type of UCI. The UE feeds back CSI to the base station in the form of a CSI report, which can provide the base station with the parameters required for transmission.

[0056] The configuration related to CSI reporting is mainly determined by the high-level parameter CSI-ReportConfig. According to the different reporting types (reportConfigType) in CSI-ReportConfig, CSI reporting can be divided into periodic CSI reporting, semi-persistent (semiPersistentOnPUCCH or semiPersistentOnPUSCH) CSI reporting and aperiodic CSI reporting. The specific CSI reporting content is configured by the reportQuantity field in CSI-ReportConfig. For example, reportQuantity can be configured as:

[0057] 'cri-RSRP' feedback includes the CSI-RS Resource Indicator (CRI) and Layer 1 Reference Signal Receiving Power (L1-RSRP), which are beam index information and beam quality information, respectively. It can be used for CSI-RS-based beam management.

[0058] 'ssb-Index-RSRP': This feedback includes the synchronization signal block resource indicator (SSBRI) and L1-RSRP, which are beam index information and beam quality information, respectively. This can be used for SSB-based beam management.

[0059] ●And so on.

[0060] At present, regarding the reporting content related to the beam management initiated by the UE, the UE will detect the event (UEI BM event) of the UE-initiated beam management according to specific criteria. The event of the UE-initiated beam management here at least includes beam switching. The specific criteria are not limited in this application.

[0061] After detecting the UEI BM event, the UE may actively report the occurrence of the event to the base station and send beam reporting information related to beam management (e.g., beam switching) in the UEI BM event. The beam reporting information may optionally include one or more of the following information about the new beam (target beam to be selected, i.e., candidate beam):

[0062] CRI / SSBRI information;

[0063] L1-RSRP / L1-SINR (Layer 1 Signal Interference Noise Ratio) information;

[0064] Physical cell ID information;

[0065] ●Unified Transmission Configuration Indication State ID (TCI-StateId);

[0066] ●And so on.

[0067] According to current standardization discussions, the network can configure a scheduling request (SR) associated with a UEI BM for the UE. Upon detecting a UEI BM event, the UE sends this SR to notify the base station of the occurrence. Alternatively, the network can configure dedicated notification information associated with the UEI BM for the UE to notify the base station of the occurrence. Furthermore, the SR or dedicated notification information associated with the UEI BM can optionally carry other information, such as the bit size of the beam report information.

[0068] In the embodiment of the present application, for the convenience of explanation, the SR associated with the UEI BM or the dedicated notification information associated with the UEI BM is collectively referred to as the first SR. Optionally, the first SR (e.g., the SR associated with the UEI BM or the dedicated notification information associated with the UEI BM) also carries other information. In addition, the beam report information related to beam management in the UEI BM event is collectively referred to as the first information.

[0069] In addition, the reporting process and resource allocation method in UEI BM are currently described in the agreement of 3GPP RAN1#116 meeting as follows:

[0070] When a UE detects a UEI BM event, it can report beam reporting information through different channels. According to the conclusions of the 3GPP RAN1#116 meeting, UEI BM reporting can be based on either the MAC-CE (Media Access Control Element) or the UCI.

[0071] There are several ways to report based on UCI.

[0072] Method 1: Dynamic scheduling based on base stations, including the following steps:

[0073] Step 1: After detecting a UEI BM event, the UE sends the first SR.

[0074] Step 2: The UE receives DCI format 0_0, DCI format 0_1, or DCI format 0_2 (hereinafter referred to as uplink scheduling grant DCI, or UL DCI). The UL DCI can schedule uplink resources and includes a field requesting to send first information.

[0075] Step 3: The UE sends the first information on the uplink resource (such as PUSCH) scheduled by the UL DCI.

[0076] FIG1 is a schematic diagram of UEI BM reporting based on dynamic scheduling of a base station. As shown in FIG1 , the UE sends a first SR, receives a ULDCI sent by a base station, and then sends first information on a PUSCH scheduled by the ULDCI.

[0077] Method 2: Based on pre-configured resources, including the following steps:

[0078] Step 1: The UE receives configuration information from a base station. The configuration information pre-configures periodic or semi-persistent resources. A reporting opportunity occurs every time a time period T passes. The reporting opportunity can be used to report the first information.

[0079] Step 2: After detecting the UEI BM event, the UE sends the first information on the pre-configured resources.

[0080] FIG2 is a schematic diagram of UEI BM reporting based on pre-configured resources. As shown in FIG2 , RS1 to RS4 are reference signals for UEI BM measurement. After a UEI BM event occurs, the UE directly sends the first information on the pre-configured resources.

[0081] In the above example, the pre-configured resources may be configured to be used only for UEI BM reporting, or may be configured to be used to send other content without UEI BM reporting.

[0082] Method 3: Based on the first SR and pre-configured resources (pre-configured), including the following steps:

[0083] Step 1: The UE receives configuration information from a base station. The configuration information pre-configures periodic or semi-persistent resources. A reporting opportunity occurs every time a time period T passes. The reporting opportunity can be used to report the first information.

[0084] Step 2: After detecting the UEI BM event, the UE sends the first SR;

[0085] Step 3: The UE sends the first information on the pre-configured resources. That is, if the UE does not send the first SR, the first information will not be generated.

[0086] Figure 3 is another schematic diagram of UEI BM reporting based on pre-configured resources. As shown in Figure 3, RS1~RS4 are reference signals for UEI BM measurement. After a UEI BM event occurs, the UE first sends a first SR and then sends the first information on the pre-configured resources.

[0087] In the above example, the pre-configured resources may be configured to be used only for UEI BM reporting, or may be configured to be used to send other content without UEI BM reporting.

[0088] In the aforementioned method 3, the first SR is sent first, followed by the first message sent on pre-configured resources. If the first SR is not sent (i.e., no UEI BM event occurs), the pre-configured resources can be used to send other content. Compared to methods 1 and 2, method 3 ensures the timeliness of UEI BM reporting and improves resource utilization efficiency.

[0089] In the existing solution, in order to increase reliability, the SR can be retransmitted, as shown in FIG4 , that is, reliability is increased by transmitting the SR multiple times until the UE receives the ULDCI for scheduling uplink resources, and then sends the PUSCH scheduled by the ULDCI.

[0090] However, for the above-mentioned method three, after the UE sends the first SR, it will not receive UL DCI, and the UE cannot confirm whether the base station has correctly received the first SR. If the base station does not correctly receive the first SR, the base station may schedule the UE to transmit other content on the pre-configured resources (i.e., at the next reporting opportunity), which will cause the UE to send the first information and send other scheduled content in conflict. As shown in Figure 5, after the UE sends the first SR, it cannot confirm whether the base station has received the first SR, and still sends the first information on the pre-configured resources, but at this time the base station may not receive the first SR. In the case of not receiving the first SR, the base station will schedule the pre-configured resources here to send other information (other information scheduled by gNB), and the other information conflicts with the first information to be sent by the UE. It can be seen that for the above-mentioned method three, the reliability of the UE sending the first SR cannot be guaranteed, and it may cause the UE to send the first information and other information scheduled by the base station to conflict.

[0091] In view of the above problems, this application is proposed.

[0092] The embodiments of the present application are described below with reference to the accompanying drawings and specific implementation methods.

[0093] Embodiments of the first aspect

[0094] An embodiment of the present application provides a beam management method, which is described from the perspective of a terminal device.

[0095] FIG6 is a schematic diagram of a beam management method according to an embodiment of the present application. As shown in FIG6 , the method includes:

[0096] 610. The terminal device receives a CSI reporting configuration, where the CSI reporting configuration includes at least one CSI-ReportConfig related to UEI BM reporting, and the CSI-ReportConfig is associated with at least one first SR.

[0097] 620, the terminal device sends at least one first SR after detecting a UEI BM event;

[0098] 630. After sending all at least one first SR, the terminal device sends the first information at the first reporting opportunity.

[0099] It is worth noting that FIG6 above is merely a schematic illustration of an embodiment of the present application, and the present application is not limited thereto. For example, the execution order of the above operations may be adjusted, other operations may be added or some operations may be reduced, and the objects of the above operations may be adjusted. Those skilled in the art may make appropriate modifications based on the above content, and are not limited to the description of FIG6 above.

[0100] According to the above embodiment, in the UEI BM process, for the scenario of using the first SR and pre-configured resources to report the UEI BM, the terminal device sends multiple first SRs after detecting the UEI BM event, and then sends the first information at the first reporting opportunity, which can improve the reliability of the terminal device sending the first SR, and can reduce or eliminate the possibility of the first information sent by the terminal device conflicting with other information scheduled by the network device.

[0101] In the above embodiment, the first SR includes at least SR information associated with the UEI BM or dedicated notification information associated with the UEI BM; it may also include other information related to the beam report, such as the number of bits in the beam report. In the embodiment of the present application, there is no restriction on the name of the first SR, and it can be called "new SR", "SR", "notification information", etc. The relevant content of the first SR has been explained above and will not be repeated here.

[0102] In the above embodiment, the first information includes at least beam report information related to beam management (e.g., beam switching) in the UEI BM event. The beam report information is, for example, at least one of the following:

[0103] CRI / SSBRI (Channel State Information Reference Signal Resource Indicator / Synchronization Signal Block Resource Indicator) information;

[0104] L1-RSRP / L1-SINR (Layer 1 Reference Signal Received Power / Layer 1 Signal-to-Noise Ratio) information;

[0105] Physical cell identification information;

[0106] Transmission configuration indication status flag.

[0107] The relevant content of the beam report information has been explained previously and will not be repeated here.

[0108] In the above embodiment, the first reporting opportunity is the earliest reporting opportunity after the first SR. For example, the reporting type (reportConfigType) of the CSI-ReportConfig related to the UEI BM is periodic (periodic) or semi-persistent (semiPersistentOnPUCCH or semiPersistentOnPUSCH). After the CSI-ReportConfig configuration takes effect or is activated, there is a corresponding reporting opportunity every period T, and the reporting content configured by the reportQuantity field in the CSI-ReportConfig can be reported at the corresponding reporting opportunity. If the terminal device sends the first SR within a certain period, the earliest reporting opportunity after the first SR is called the first reporting opportunity.

[0109] In some embodiments, all first SRs are sent within the same pre-configured resource period, which is the period T corresponding to the aforementioned CSI-ReportConfig. For example, when the CSI-ReportConfig is associated with multiple first SRs, after detecting the UEI BM, the UE sends the multiple first SRs before a specific time threshold (referred to as the first threshold) before the next reporting opportunity (the aforementioned first reporting opportunity).

[0110] In some embodiments, the time interval between the end time of the first SR with the latest end time among the at least one first SR and the next reporting opportunity (the first reporting opportunity) is not less than a preset first threshold. For example, the first threshold is T threshold , that is, the time interval between the end time of the latest sent first SR and the next reporting opportunity is not less than T threshold .

[0111] In the embodiment of the present application, there is no restriction on the manner of associating the CSI-ReportConfig with the first SR. For example, a list of first SRs associated with the CSI-ReportConfig may be configured in the CSI-ReportConfig.

[0112] In some embodiments, the at least one first SR may occupy the same frequency domain resources, that is, the at least one first SR is TDM; or occupy the same time domain resources, that is, the at least one first SR is FDM; or partially occupy the same frequency domain resources, or partially occupy the same time domain resources, that is, the at least one first SR is a combination of TMD and FDM.

[0113] The following examples illustrate this.

[0114] Figure 7 illustrates the association between a CSI-ReportConfig that can be used for UEI BM reporting and three primary SRs. In this example, a CSI-ReportConfig that can be used for UEI BM reporting is configured to be associated with three primary SRs: New SR1, New SR2, and New SR3. After detecting a UEI BM event, the UE sends these three primary SRs before the next reporting opportunity.

[0115] Figure 8 is a schematic diagram of a terminal device reporting three first SRs (New SR1, New SR2, New SR3) and first information (beam reporting) after detecting a UEI BM event. As shown in Figure 8, New SR1 and New SR2 occupy the same time domain resources, New SR3 and New SR2 occupy the same frequency domain resources, and the transmission time of New SR3 is after New SR2. The time difference between the end time t1 of the latest transmission time New SR3 and the next reporting opportunity is not less than T threshold .

[0116] In the examples of FIG. 7 and FIG. 8 , the CSI-ReportConfig is associated with three first SRs as an example, but the present application is not limited thereto. The CSI-ReportConfig may also be associated with other numbers of first SRs, such as 2 or more first SRs.

[0117] In the above example, according to the above configuration, after detecting the UEI BM event, the UE sends multiple first SRs (New SR1, New SR2, New SR3), and reports the first information at the next reporting opportunity (first reporting opportunity) corresponding to the reporting period of the above first SR.

[0118] In the above embodiment, the number of first SRs (New SRs) is 3, and the time-frequency resources occupied by these 3 first SRs are shown in Figure 8 as an example. The present application is not limited to this, and the number of first SRs and the occupied time-frequency resources can also be other.

[0119] The above embodiments are merely exemplary of the present invention, but the present invention is not limited thereto. Appropriate modifications may be made based on the above embodiments. For example, the above embodiments may be used alone, or one or more of the above embodiments may be combined.

[0120] According to the method of an embodiment of the present application, in the UEI BM process, for the scenario of using the first SR and pre-configured resources to report the UEI BM, the terminal device sends multiple first SRs after detecting the UEI BM event, and then sends the first information at the first reporting opportunity. This can improve the reliability of the terminal device sending the first SR, and can reduce or eliminate the possibility of the first information sent by the terminal device conflicting with other information scheduled by the network device.

[0121] Embodiments of the second aspect

[0122] An embodiment of the present application provides a beam management method, which is described from the side of the terminal device, and the contents that are the same as the embodiment of the first aspect will not be repeated.

[0123] FIG9 is a schematic diagram of a beam management method according to an embodiment of the present application. As shown in FIG9 , the method includes:

[0124] 910. The terminal device receives a CSI reporting configuration, where the CSI reporting configuration includes at least one CSI-ReportConfig related to UEI BM reporting, and the CSI-ReportConfig is associated with at least one first SR.

[0125] 920. After detecting a UEI BM event, the terminal device sends the at least one first SR.

[0126] 930. After receiving the second information, the terminal device sends the first information at the first reporting opportunity. The second information is a confirmation that the first SR is successfully received by the network device.

[0127] It is worth noting that FIG9 above is merely a schematic illustration of an embodiment of the present application, and the present application is not limited thereto. For example, the execution order of the above operations may be adjusted, other operations may be added or some operations may be reduced, and the objects of the above operations may be adjusted. Those skilled in the art may make appropriate modifications based on the above content, and are not limited to the description of FIG9 above.

[0128] According to the above embodiment, in the UEI BM process, for the scenario of using the first SR and pre-configured resources to report the UEI BM, the terminal device sends at least one first SR after detecting the UEI BM event, but sends the first information at the first reporting opportunity after receiving the confirmation of the first SR from the network device (second information). Thus, the reliability of the terminal device sending the first SR can be improved, and the possibility of conflict between the first information sent by the terminal device and other information scheduled by the network device can be reduced or eliminated.

[0129] In the above embodiment, the meanings of the first SR, the first information, and the first reporting opportunity are the same as those in the embodiment of the first aspect, and their contents are incorporated herein and will not be repeated here.

[0130] In the above embodiment, the second information is confirmation information (ie, ACK information) sent by the network device to the terminal device, which may be 1-bit information, used to confirm that the network device has normally received the first SR.

[0131] In some embodiments, the second information is carried by DCI format 1_1, or by DCI format 1_2, or by DCI format 1_3. To carry the second information, the above DCI format can reuse existing fields or add new fields to carry 1 bit of the second information (i.e., ACK information).

[0132] In some embodiments, the above-mentioned DCI format 1_1 or DCI format 1_2 or DCI format 1_3 can be used for downlink allocation (DCI format 1_1 / 1_2 / 1_3 with DL assignment) or not used for downlink allocation (DCI format 1_1 / 1_2 / 1_3 without DL assignment), and this application does not impose any restrictions on this.

[0133] In some embodiments, the time interval between the end time of the second information and the next reporting opportunity (first reporting opportunity) is not less than a preset second threshold. That is, the event of the terminal device receiving the second information must be sent before a specific time threshold (second threshold) before the next reporting opportunity (first reporting opportunity). For example, the event threshold is T threshold_ACK , that is, the time difference between the end time of the second information and the next reporting opportunity (the first reporting opportunity) is not less than T threshold_ACK .

[0134] In some embodiments, after the terminal device receives the second information, it indicates that the network device has received the first SR, and the terminal device stops sending the remaining first SRs that have not been sent.

[0135] In some embodiments, if the terminal device does not receive the second information, the network device may not receive the first SR. In order to avoid the terminal device sending the first information at this time and the possibility of conflict with other information scheduled by the network device, the terminal device does not send the first information at the next reporting opportunity (the first reporting opportunity).

[0136] The following examples illustrate this.

[0137] FIG10 is a schematic diagram showing that a terminal device receives second information before the starting point of a second threshold time and reports first information at a first reporting opportunity.

[0138] As shown in Figure 10, the terminal device detects the UEI BM event, sends the first SR, and the time interval from the end time of receiving the second information to the next reporting opportunity is not less than T threshold_ACK , the terminal device reports the first information (ie, the beam report related to UEI BM) at the next reporting opportunity (the first reporting opportunity).

[0139] FIG11 is a schematic diagram showing that a terminal device receives second information after a time starting point of a second threshold and does not report the first information at the first reporting opportunity.

[0140] As shown in Figure 11, the terminal device detects the UEI BM event, sends the first SR, and then receives the second information, but the interval between the end time of receiving the second information and the next reporting opportunity is less than T threshold_ACK , if the threshold requirement is not met, the terminal device will not report the first information (ie, the beam report related to the UEI BM) at the next reporting opportunity (the first reporting opportunity).

[0141] FIG12 is a schematic diagram showing that the terminal device does not receive the second information after the second threshold and does not report the first information at the first reporting opportunity.

[0142] As shown in Figure 12, the terminal device detects the UEI BM event, sends the first SR, and does not receive the second information. Then, the terminal device will not report the first information (i.e., the beam report related to UEI BM) at the next reporting opportunity (the first reporting opportunity).

[0143] In the examples of Figures 10 to 12, the terminal device sends a first SR after detecting a UEI BM event. The present application is not limited to this. In some possible implementations, the terminal device may also send multiple first SRs after detecting a UEI BM event. Please refer to the embodiment of the first aspect for details, which will not be repeated here.

For example, the above embodiments may be used alone, or one or more of the above embodiments may be combined.

[0145] According to the method of the above embodiment, in the UEI BM process, for the scenario of using the first SR and pre-configured resources to report the UEI BM, the terminal device sends at least one first SR after detecting the UEI BM event, but sends the first information at the first reporting opportunity after receiving the confirmation (second information) of the first SR from the network device. Thus, the reliability of the terminal device sending the first SR can be improved, and the possibility of the first information sent by the terminal device conflicting with other information scheduled by the network device can be reduced or eliminated.
