[0072] Figure 13 This article presents another example of the topic described in it; Detailed Implementation
[0073] Figure 1 The illustration shows an example of a network 100 comprising multiple network nodes, including terminal node 110, access node 120, and one or more core nodes 129. Terminal node 110 and access node 120 communicate with each other. One or more core nodes 129 communicate with access node 120.
[0074] In this example, network 100 is a radio telecommunications network in which at least some terminal nodes 110 and access nodes 120 communicate with each other by transmitting / receiving radio waves.
[0075] In some examples, one or more core nodes 129 can communicate with each other. In some examples, one or more access nodes 120 can communicate with each other.
[0076] Network 100 may be a cellular network comprising multiple cells 122, each served by an access node 120. In this example, the interface between terminal node 110 and access node 120 defining cell 122 is wireless interface 124.
[0077] Access node 120 is a cellular radio transceiver. Terminal node 110 is a cellular radio transceiver.
[0078] In the illustrated example, cellular network 100 is a 3GPP network, where terminal node 110 is a user equipment (UE) and access node 120 is a base station.
[0079] In the specific example illustrated, network 100 is an Evolved Universal Terrestrial Radio Access Network (E-UTRAN). The E-UTRAN consists of E-UTRAN Node Bs (eNBs) 120 that provide E-UTRA user plane and control plane (RRC) protocol termination to UE 110. The eNBs 120 are interconnected with each other via X2 interface 126. The eNBs are also connected to the Mobility Management Entity (MME) 129 via S1 interface 128.
[0080] In other examples, network 100 is a next-generation (or new radio, NR) radio access network (NG-RAN). NG-RAN consists of gNodeBs (gNBs) 120 that provide user plane and control plane (RRC) protocol termination to UE 110. gNBs 120 are interconnected via X2 / Xn interfaces 126. gNBs are also connected to the Access and Mobility Management Function (AMF) via N2 interfaces 128.
[0081] Figure 2A and Figure 2B The illustration shows an example of a node in a radio telecommunications network 100. This node is device 10. Device 10 can function as user equipment 110 or other terminal node, or it can function as a base station 120 or other access node.
[0082] The device 10 includes a communication circuitry 30 configured to communicate in a radio telecommunications network 100 via one or more antenna panels 20. The antenna panel 20 may include a single antenna element 22 or may include multiple antenna elements 22.
[0083] Figure 2A The diagram illustrates a device 10 having multiple antenna panels 20A and 20B. In some scenarios, the device may use antenna panel 20A. In other scenarios, the device 10 may use antenna panel 20B. Therefore, the device 10 can have a variable antenna configuration.
[0084] Figure 2B The diagram illustrates a device 10 including at least one antenna panel 20A. The antenna panel 20A includes a plurality of antenna elements 22. The device 10 can perform beamforming using the antenna elements 22 by adapting which antenna element 22 is used or by changing the relative gain and / or phase shift applied to the antenna elements 22. Therefore, the device 10 can have a variable antenna configuration.
[0085] In some examples, such as Figure 2B The device 10 illustrated herein may include one or more additional antenna panels 20B, such as... Figure 2AAs illustrated in the figure. The additional antenna panel or additional multi-antenna panel may include one or more antenna elements 22. Each of the antenna elements 22 of the antenna panel and the antenna panel may be selectively controlled for beamforming.
[0086] Therefore, it should be understood that the antenna configuration of the device 10 can be varied by selecting which of the antenna panels 20A, 20B is operable, selecting which antenna elements 22 within the antenna panels are operable, or by applying variable weights and / or phase shifts to the antenna elements 22 to provide beamforming.
[0087] Each different antenna configuration 12 has a different associated gain, which depends on the radiation beam pattern produced by the antenna configuration 12. Therefore, for example, a narrower beam pattern will have a higher gain than a wider beam pattern.
[0088] Figure 3 The figure illustrates an example in which user equipment 110 measures 42 a probe signal transmitted by base station 120. Measurement 42 occurs during measurement scenario 40. The figure also illustrates a communication scenario 50 in which user equipment 110 communicates 52 with the same base station 120. Communication 52 may be, for example, the transmission and / or reception of data.
[0089] The measurement M performed by user equipment 110 during measurement 42 in measurement scenario 40 depends on the transmitting antenna configuration 12 at base station 120 and the receiving antenna configuration 12 at user equipment 110. The strength of the received data signal received at user equipment 110 depends on both the transmitting and receiving antenna configurations at base station 120 and base station 120. Therefore, the measurement M performed by user equipment 110 during measurement scenario 40 may be inaccurate for data communication scenario 50. This could be because the antenna configuration 12 used by base station 120 changes between measurement scenario 40 and data communication scenario 50. Alternatively, it could be because the antenna configuration 12 used by user equipment 110 changes between measurement scenario 40 and data communication scenario 50.
[0090] Therefore, the link budget measured by user equipment 110 during measurement scenario 40 may need to be "corrected" to accurately represent the potential link budget available during data communication scenario 50.
[0091] Link budget correction—antenna configuration correction (ACC)—may have a component associated with changes in antenna configuration 12 used by base station 120 between measurement scenario 40 and data communication scenario 50. Link budget correction may also have a component associated with changes in antenna configuration 12 used by user equipment 110 between measurement scenario 40 and data communication scenario 50. It is desirable to compensate for both corrections. This will allow communication between user equipment 110 and network 100 to be controlled by a process and decision based on the anticipated potential link budget of the corrected data communication scenario 50.
[0092] Let ACC xY This represents the correction component of the link budget associated with changes in the antenna configuration used by node Y between measurement scenario 40 and data communication scenario 50 for link x. Node Y can be a user equipment (UE) 110 or a base station (BTS) 120. Link x can be used for serving (primary) base station 120. p (BTS) p ) or (where appropriate, such as for handover) for adjacent base stations 120 n (BTS) n )
[0093] Therefore, for the service base station 120 p (BTS) p The correction of the link budget can have the following characteristics:
[0094] i) with the serving base station 120 p (BTS) p The component ACC associated with the change in antenna configuration 12 used between measurement scenario 40 and data communication scenario 50. pBTS .
[0095] ii) and the user equipment (UE) using the serving base station 120 p The component ACC associated with the change in antenna configuration 12 used between measurement scenario 40 and data communication scenario 50. pUE .
[0096] Therefore, for adjacent base stations 120 n (BTS) n The correction of the link budget can have the following characteristics:
[0097] i) with adjacent base station 120 n (BTS) n The component ACC associated with the change in antenna configuration 12 used between measurement scenario 40 and data communication scenario 50. nBTS .
[0098] ii) with the user equipment (UE) (using adjacent base station 120)n The component ACC associated with the change in antenna configuration 12 used between measurement scenario 40 and data communication scenario 50. nUE .
[0099] With service base station 120 p (BTS) p The correction for the link budget associated with the link between ACC and user equipment 110 is (assuming dB units): pBTS +ACC pUE This indicates the gain difference of this link between measurement scenario 40 and data communication scenario 50.
[0100] 120 adjacent base stations n (BTS) n The correction for the link budget associated with the link between ACC and user equipment 110 is (assuming dB units): nBTS +ACC nUE This indicates the gain difference of this link between measurement scenario 40 and data communication scenario 50.
[0101] The process and decisions can be based on the anticipated potential link budget of the corrected data communication scenario 50. This process and decisions can directly or indirectly control the beam selection used for user equipment communication.
[0102] This process or decision can occur at the user equipment, such as triggering a measurement report for beam selection. This process or decision can also occur at the serving base station 120. p (BTS) p A process or decision at a location, such as beam selection.
[0103] Antenna Configuration Correction (ACC) pUE ACC nUE The UE components are known at user equipment 110. Antenna configuration correction (ACC) pBTS The serving BTS component is known at the serving BTS. Antenna configuration correction ACC nBTS The adjacent BTS components are known at the adjacent BTS.
[0104] Antenna configuration correction ACC pUE ACC nUE UE components (or depending on their values) can be transmitted from user equipment 110 to serving base station 120. p (BTS) p In at least some examples, antenna configuration correction ACC nBTS The adjacent BTS component (or depending on its value) can be transmitted from the adjacent BTS to the serving base station 120.p (BTS) p ).
[0105] In at least some examples, the BTS component ACC of antenna configuration correction. pBTS ACC nBTS (Or, depending on their values) can be transmitted from the service BTS to UE 110.
[0106] In some examples, it may be desirable to transmit representations of antenna configuration correction (ACC) or antenna configuration correction components (ACC). pUE ACC nUE ACC pBTS ACC nBTS The index is not the value of the transmitted antenna configuration correction or the value of the antenna configuration correction component. Such an index is the Antenna Configuration Correction Index (ACCI).
[0107] like Figure 4 As illustrated in the diagram, ACC can be, for example, process 60 used to generate ACCI.
[0108] For example, process 60 may involve quantization, where ACCI represents the number of steps within ACC. Any suitable quantization process is appropriate.
[0109] For example
[0110] ACCI = floor (ACC / step)
[0111] The ACCI-based ACC quantization version is step. ACCI.
[0112] Any suitable step size can be used. The step size can be fixed or variable. If variable, it can be determined by the user equipment 110 or the serving base station 120. p Definition. A suitable step size can be 1-5 dB, for example, 3 dB.
[0113] In some examples,
[0114] ACCI xY = log2(R xY ) or ACC xY = log2(R xY )
[0115] Where R xY This represents the relative maximum directionality (maximum gain potential) that can be achieved in data communication.
[0116] In one example (a),
[0117] RxY = Total number of antenna elements 22 that can be configured at node Y to serve link x during data communication scenario 50 / Number of antenna elements 22 that are configured at node Y to serve link x during measurement scenario 40.
[0118] In another example (b),
[0119] R xY = The configured angular radiation beamwidth used at node Y to serve link x during measurement scenario 40 / The minimum configurable angular radiation beamwidth available at node Y to serve link x during data communication scenario 50.
[0120] In another example (c),
[0121] R xY = The maximum linear gain that can be configured at node Y to serve link x during data communication scenario 50 / The linear gain that is configured at node Y to serve link x during measurement scenario 40.
[0122] Example (a) is available when a subset of the antenna elements 22 in the antenna panel 20 is used in the measurement scenario 40.
[0123] Examples (b) and (c) can also be used in this example, and they are also applied when different weights are used for the antenna elements 22 of the antenna panel 20 between measurement scenario 40 and communication scenario 50.
[0124] ACCI xY It can be transmitted as a short sequence.
[0125] like Figure 5 As illustrated in the figure, in at least some examples, UE-based ACCI (ACCI) pUE ACCI nUE (or, depending on their values, are transmitted from user equipment 110 to serving base station 120) p (BTS) p ).
[0126] In at least some examples, adjacent BTS ACCI (ACCI) nBTS (or, depending on its value, can be derived from adjacent base stations 120) n (BTS) n It was transmitted to the serving base station 120 p (BTS) p ).
[0127] In at least some examples, the BTS component of ACCI (ACCI) pBTS ACCI nBTS(or, depending on their values, can be obtained from serving base station 120) p (BTS) p It was transmitted to UE 110.
[0128] ACC or ACCI can be used in beam selection process 70. Beam selection process 70 can involve serving base station 120. p (BTS) p Therefore, it may be desirable to serve base station 120. p (BTS) p ) Receives all ACC or ACCI.
[0129] The beam selection process can be combined with inter-cell selection ( Figures 6A-6C Related processes, such as handover (HO) or conditional handover (CHO). This process can be a decision to handover or not to handover, or a preliminary step to that decision. Beam selection can include the selection of a new beam for the new serving base station 120 (previously a neighboring base station). The four components ACC can be corrected using antenna configuration. pBTS ACC pUE ACC nBTS ACC nUE (or ACCI) pBTS ACCI pUE ACCI nBTS ACCI nUE ).
[0130] Beam selection can be intra-cell selection ( Figures 7A-7B For example, beam management (BM). This process can be a decision about whether to change the beam, or a preliminary step towards that decision. Beam selection can include the selection of a new beam for the same serving base station 120. The two components ACC can be corrected using the antenna configuration of the serving cell. pBTS ACC pUE (or ACCI) pBTS ACCI pUE ).
[0131] If a new beam is selected, then antenna configuration 12 for that link is used. This may result in the use of a different antenna panel 20 or a different antenna element 22 for the antenna panel at UE 110, or the use of different complex weights for the antenna element 22 of the antenna panel 20 at UE 110.
[0132] exist Figure 6A In the communication scenario 50, user equipment 110 communicates with serving base station 120. p Perform data communication 52. Figure 6B The diagram illustrates measurement scenario 40. User equipment 110 performs operations on the serving base station 120. pThe transmitted reference signal is measured 42, and the source signal from the serving base station 120 is determined. p Estimated link budget M for the downlink to user equipment 110 p User equipment 110 performs operations on adjacent base stations 120. n The transmitted reference signal is measured 42, and the source signal from the adjacent base station 120 is determined. n Estimated link budget M for the downlink to user equipment 110 n .
[0133] In this example, beam selection process 70 causes beam selection from serving base station 120. p To adjacent base station 120 n Switching, such as Figure 6C The image shows the serving base station 120. p Therefore, a change occurs. During communication scenario 50, mobile device 110 and new serving base station 120... p Communication 52.
[0134] Figure 7A The illustration shows an example where user equipment 110 measures 42 a reference signal transmitted by base station 120 using antenna beam 72 during measurement scenario 40. Beam selection process 70 results in the selection of a new beam 72, which is used for data communication 52 between user equipment 110 and base station 120, such as... Figure 7B As shown in the diagram.
[0135] Figure 8 The diagram illustrates applications for control such as Figures 6A to 6C The illustration shows an example of a handover or conditional handover. During measurement scenario 40, user equipment 110 measures 42 with serving base station 120. p Associated downlink budget M p During measurement scenario 40, user equipment 110 measures 42 and the neighboring base station 120. n Associated downlink budget M n .
[0136] The step size value is either fixed or provided by the user equipment 110 to the serving base station 120. p Or by serving base station 120 p Provided to user equipment 110.
[0137] The step size value was used to quantize ACC. pUE To generate ACCI pUE And was used to quantify ACC nUE To provide ACCI nUE ACCI pUE Provided by user equipment 110 to serving base station 120 p ACCInUE Provided by user equipment 110 to serving base station 120 p In addition, user equipment 110 also identifies neighboring base stations 120 received by user equipment 110 during measurement scenario 40. n Beam 72, to generate downlink budget value M n .
[0138] In some examples, the measurement M n and M p It can also be sent from user equipment 110 to serving base station 120 p .
[0139] Measurement M n and M p They can be transmitted together or separately. The identifier of beam 72 can be associated with the measurement M for that beam 72. n They were sent together.
[0140] From adjacent base station 120 n Identifier for receive beam 72.
[0141] In response, serving base station 120 p to adjacent base station 120 n A request including the identifier of beam 72 is sent. In response, the serving base station 120... p To the serving base station 120 p Provide ACC nBTS or ACCI nBTS ACC nBTS or ACCI nBTS With the neighboring base station 120 identified in the request n Beam correlation.
[0142] In some examples, the request may also include a step value.
[0143] Next, we will use four indices: ACC or ACCI (ACC). pUE ACC pBTS ACC nUE ACC nBTS ) to perform the beam selection process 70.
[0144] User equipment 110 and service base station 120 p Communication between indices can occur, for example, at the physical layer (L1), at the media access control layer (L2), or at the radio resource control layer (L3).
[0145] The beam selection process 70 may include, for example, ACC or ACCI: periodic cell reporting for serving and / or neighboring cells, event-triggered reporting, traditional handover, and conditional handover. These can be used for beam-managed handover and conditional handover.
[0146] Some of all these processes 70 can be performed by UE 110 ( Figure 9A For example, the triggering of conventional and / or conditional switching can depend on one or more ACCs or ACCIs.
[0147] Some of all these processes 70 can be handled by the serving base station 120 p implement( Figure 9A For example, the evaluation of periodic measurement reports from the UE can depend on one or more ACCIs. This can be used, for example, for beam management.
[0148] Some of the processes can be performed partly by UE 110 and partly by serving base station 120. p implement( Figure 9B For example, the event triggering process 72 that triggers the handover measurement report at UE 110 may depend on one or more ACCs or ACCIs, and the generation or processing of the handover measurement report 72 may depend on one or more ACCs or ACCIs.
[0149] The current A3 event trigger equation used at UE 110 to send the handover measurement report is:
[0150] Mn + Ofn + Ocn – Hys>Mp + Ofp + Ocp + Off
[0151] Mp and Mn are the serving (primary) base station 120 p and adjacent base station 120 n Measurements at UE 110. Parameters Ofn, Ofp, Off, and Hys are offset parameters.
[0152] Ocn and Ocp are individual cell offsets. (Adjacent base station 120) n The measurement Mn can depend on the neighboring base stations 120 n And thus upgraded (or downgraded). Serving base station 120 p The measured Mp can depend on the serving base station 120 p And can be upgraded (or downgraded). Ocn and Ocp can be configured via network 100.
[0153] Ofn depends on the measurement of adjacent base stations 120 on it. nThe frequency offset of the frequency. If network 100 wants to report cells on that frequency layer in advance, i.e., if it wants to force a switch to such a cell (e.g., for load balancing, better speed support, or any other traffic control strategy), network 100 can assign a positive offset.
[0154] Ofp depends on the measurement service base station 120 on it. p The frequency offset of the frequency.
[0155] The A3 event triggering equation can be explicitly modified to include ACCI:
[0156] Mn + Ofn + Ocn – Hys + (stepx(ACCI nUE + ACCI nBTS Mp + Ofp + Ocp + Off + (stepx(ACCI pUE + ACCI pBTS ))
[0157] UE 100 determines ACCI nUE ACCI pUE The corresponding base station determines ACCI. nBTS ACCI pBTS .
[0158] Therefore, UE 110 needs to obtain ACCI. nBTS ACCI pBTS Or depends on ACCI nBTS ACCI pBTS The value. UE 110 has already obtained or needs to obtain the step size.
[0159] The following example illustrates how UE 110 can obtain ACCI. nBTS ACCI pBTS Or depends on ACCI nBTS ACCI pBTS The value of .
[0160] In the following text, we assume that the serving base station is 120. p With ACCI pBTS And it has already been transferred from the adjacent base station 120 n Obtained ACCI nBTS .
[0161] i) Service base station 120 p Send ACCI to UE 110 in measurement event condition 71 nBTS ACCI pBTSUE 110 uses the following as a trigger: Mn + Ofn + Ocn – Hys + (stepx (ACCI) nUE + ACCI nBTS ))>Mp + Ofp +Ocp + Off + (step x (ACCI pUE + ACCI pBTS ))
[0162] ii) Service base station 120 p Update Ocn and Opn:
[0163] Ocn -> Ocn + offset n offset n = stepx ACCI nBTS
[0164] Ocp -> Ocp + offset p offset p = stepx ACCI pBTS
[0165] The updated Ocn and Opn are sent to UE 110 in measurement event condition 71.
[0166] UE 110 uses the following as a trigger:
[0167] Mn + Ofn + Ocn – Hys + (stepx ACCI nUE )>Mp + Ofp + Ocp + Off + (step xACCI pUE )
[0168] iii) Serving base station 120 p Update Ocn and Opn:
[0169] ACCI nUE ACCI pUE Provided by UE 110 to serving base station 120 p .
[0170] Ocn -> Ocn + offset n offset n = stepx (ACCI nUE + ACCI nBTS )
[0171] Ocp -> Ocp + offset p offset p= stepx (ACCI pUE + ACCI pBTS )
[0172] The updated Ocn and Opn are sent to UE 110 in measurement event condition 71.
[0173] UE 110 uses the following as a trigger:
[0174] Mn + Ofn + Ocn – Hys>Mp + Ofp + Ocp + Off
[0175] iv) Service base station 120 p Only Ocn updated:
[0176] ACCI nUE ACCI pUE Provided by UE 110 to serving base station 120 p .
[0177] Ocn -> Ocn + offset, where offset = stepx (ACCI nUE + ACCI nBTS )- stepx(ACCI pUE + ACCI pBTS )
[0178] The updated Ocn is sent to UE 110 in measurement event condition 71.
[0179] UE 110 uses the following as a trigger:
[0180] Mn + Ofn + Ocn – Hys>Mp + Ofp + Ocp + Off
[0181] iv) Service base station 120 p Provide offset:
[0182] ACCI nUE ACCI pUE Provided by UE 110 to serving base station 120 p .
[0183] offset = stepx (ACCI nUE + ACCI nBTS )- stepx (ACCI pUE + ACCI pBTS )
[0184] This offset is sent to UE 110 in measurement event condition 71.
[0185] UE 110 uses the following as a trigger:
[0186] Mn + Ofn + Ocn – Hys +offset>Mp + Ofp + Ocp + Off
[0187] Figure 10 An example of a method 300 for antenna configuration compensation is shown. In particular, it is a method 300 for controlling a beam selection process 70 based on antenna configuration compensation.
[0188] In phase 301, UE 110 connects to serving gNB 120. p .
[0189] In phase 302, UE 110 reports its capabilities to the serving gNB 120. p It reports whether it is using ACCI or ACC. In some examples, it can indicate how it is using ACCI.
[0190] In phase 302, service gNB 120 p Configure the ACCI step size value (if it is dynamic) and send it to UE110.
[0191] In phase 304, the serving gNB configures the initial legacy Ocn and / or Ocp offset values or the new ACCI offset value (e.g., -10 dB) and sends it to the UE 110 to ensure that an early A3 event is triggered when needed.
[0192] In phase 305, the early A3 event is triggered at the UE.
[0193] In phase 306, UE 110 sends a request to the serving gNB 120. p Launch from measurement service gNB 120 p The RSRP value measured in the service SSB. Transmission includes ACCI. pUE .
[0194] In phase 307, UE 110 sends a request to the serving gNB 120. p Launch from measuring adjacent target gNB 120 n The RSRP value measured in the SSB. Transmission includes ACCI. nUE The launch included the adjacent target gNB 120. n The SSB indicator of the measured SSB.
[0195] In phase 308, service gNB 120 p Request neighboring target gNB 120 nThe measured ACCI of SSB ngNB The request includes neighboring target gNB 120. n The SSB indicator of the measured SSB.
[0196] In phase 309, in response, the adjacent target gNB 120 n To service gNB 120 p Send ACCI ngNB .
[0197] In phase 310, service gNB 120 p Based on all four ACCI values (ACCI nUE ACCI ngNB ACCI pUE ACCI pgNB ) to generate measurement event condition 71.
[0198] For example, the measurement event condition 71 could be:
[0199] a) The new ACCI offset value, where
[0200] Offset = ( step x (ACCI nUE + ACCI ngNB )) - ( step x (ACCI pUE + ACCI pgNB ))
[0201] b) Updated values of Ocn and / or Ocp
[0202] For example, Ocn->Ocn+offset
[0203] In phase 311, service gNB 120 p Send the updated measurement event condition 71 to UE 110.
[0204] In phase 312, event A3 is triggered by the updated measurement event condition 71 72.
[0205] Triggering conditions could be, for example:
[0206] a) Mn + Ofn + Ocn – Hys + ACCI_offset>Mp + Ofp + Ocp + Off, where the offset has been provided by the measurement event condition 71.
[0207] b) Mn + Ofn + Ocn – Hys>Mp + Ofp + Ocp + Off, where one or both of Ocn and Ocp have been updated by the measurement event condition 71.
[0208] In phase 313, UE 110 sends a request to the serving gNB 120. p Launch from measurement service gNB 120 p The RSRP value measured in the service SSB. Transmission includes ACCI. pUE .
[0209] In phase 314, UE 110 sends a request to the serving gNB 120. n Launch from measuring adjacent target gNB 120 n The RSRP value measured in the SSB. Transmission includes ACCI. nUE The launch included the adjacent target gNB 120. n The SSB indicator of the measured SSB.
[0210] In Phase 315, service gNB 120 n The switch can now be performed at the correct time by updating the HO execution threshold and / or trigger time in dB.
[0211] In phase 316, there was a successful switchover (HO) decision.
[0212] After the HO is executed, the target gNB is now a new service gNB.
[0213] In phase 317, the new service gNB 120 p (Previous target gNB 120) n Configure the ACCI step size value (if it is dynamic) and send it to the UE.
[0214] In phase 318, the new service gNB 120 p Configure the initial legacy Ocn and / or Ocp offset values or the new ACCI offset value (e.g., -10 dB) and send it to UE 110 to ensure early A3 event triggering (305) (if required).
[0215] Method 300 can be repeated.
[0216] ACC capability and ACCI step size value can be reported to the service gNB 120 through UE capability. p .
[0217] For some UEs, ACC at the UE may not be necessary, for example, if the gain difference between measurement scenario 40 and data communication scenario 50 is the same for all implemented UE antenna panels 20. Therefore, if UE 110 can report this to the serving gNB 120 pIt may be beneficial to avoid sending unnecessary information (equal ACCI values) and thus not increase overhead. ACC capability can be appended to the following commands in the RRC UE capability information.
[0218] UECapabilityInformation The UE capability information (3GPP TS 38.331, 5.6.1.3) can be updated to indicate whether ACC is supported when the ACC step size is controlled by the serving gNB or is fixed. When the ACC step size is controlled by UE 110, UECapabilityInformation (3GPP TS 38.331, 5.6.1.3) can be updated to provide values for the ACC step size.
[0219] Can be done via RRC Reconfiguration Report the ACC step size to UE 110.
[0220] ACC can be reported via RRC UE (e.g., ACCI) nUE ACCI pUE ).
[0221] It can be used MeasResultNR The command will report the RSRP value measured at UE 110 back to the serving gNB 120. p :
[0222] Use subcommands respectively ResultsSSBCell and ResultsCSI-RSCell, Report RSRP based on SSB and / or RSRP based on CSI-RS back to the service gNB.
[0223] exist MeasResultNR Add ResultsSSBCell to the command to add ssb-Cell_ACC and ssb-beam-indicator.
[0224]
[0225] If the measurement report ResultsSSBCell comes from the service base station 120 p For UE 110, the ResultsSSBCell includes data from the measurement service base station 120. p The RSRP value measured in the SSB, and ssb-Cell_ACCI includes ACCI. pUE .
[0226] If the measurement report ResultSSBCell comes from a neighboring target base station 120 n For UE 110, ResultSSBCell includes measurements from neighboring target base stations 120.n The RSRP value measured in the SSB, and ssb-Cell_ACCI includes ACCI. nUE Furthermore, the ssb-beam-Indicator includes 120 neighboring target base stations. n The measured SSB 72 SSB indicator.
[0227] exist MeasResultNR Add ResultsCSI-RSCell to the command to add csi-rs-Cell-ACC and csi-rs-beam-indicator.
[0228]
[0229] If the measurement report ResultsCSI-RSCell comes from the service base station 120 p For UE 110, the ResultsCSI-RSCell includes data from the measurement serving base station 120. p The RSRP value measured in the CSI-RS beam, and csi-rs-Cell-ACCI includes ACCI. pUE .
[0230] If the measurement report ResultsCSI-RSCell comes from a neighboring target base station 120 n For UE 110 (if supported), then ResultsCSI-RSCell includes measurements from neighboring target base stations 120. n The RSRP value measured in the CSI-RS beam, and csi-rs-Cell-ACCI includes ACCI. nUE Furthermore, the csi-rs-beam-indicator includes 120 neighboring target base stations. n The measured CSI-RS beam indicator of CSI-RS beam 72.
[0231] ACC UE (e.g., ACCI) nUE ACCI pUE This can be reported via the MAC CE component.
[0232] ACC UE (e.g., ACCI) nUE ACCI pUE This can be reported via RRCL1-RSRP.
[0233] Signaling options where L1-RSRP reports for beam management are supplemented by the ACC value of either the CRI or SSBRI #x for each report. The following example shows what the CSI report for L1-RSRP reports looks like when the UE is also configured to report ACC values.
[0234]
[0235] ACC ngNB or ACCI ngNB Reported via the Xn interface. Message passing in stages 308 and 309 above can be performed via the Xn interface.
[0236] Additionally, it can be accessed via Xn (from service gNB 110) p To the target adjacent gNB 110 n ) Requesting new information (e.g., ACC) in a HO request sent by a signal. ngNB or ACCI ngNB New information (e.g., ACC) ngNB or ACCI ngNB ) can be included through Xn (from the target adjacent gNB 110) ngNB To service gNB 110 p The HO request sent via signal is being confirmed.
[0237] In service gNB 110 p Periodic reports on gNB can be submitted using ACC or ACCI.
[0238] For example, for inter-cell beam management, serving gNB 110 p ACCI obtains its own beam 72 pUE (Visible from UE), to communicate with neighbor gNB 110 n The measurement reports were compared. Inter-cell beam management uses ACCI. pUE ACCI pBTS ACCI nUE ACCI nBTS ,
[0239] For example, periodic reports are used for beam management within a cell. If from the same service gNB 110 p The two different beams 72 are visible to UE 110 on two different panels 20A and 20B, so the serving gNB 110 p Accurate beam switching is required for the ACCI value of the UE for each link.
[0240] ACCI pUE It can be reported to the service base station 110 on a regular basis.p Always (regularly) send a message to service gNB 110 p ACCI Report pUE The advantage is that if ACCI pUE The value is suddenly changed, and it can be used to indicate the rotation of UE 110 and the switching of panel 20 used at UE 110.
[0241] Panel ID can also be associated with ACCI pUE They were sent together, or in ACCI. pUE It is sent when a significant change occurs. Each panel 20j of UE110 can have one ACCI. pUEj .
[0242] If the service is gNB 110 p If the UE 110 receives a panel switching identifier, it can revert to the initial value of Ocn / Ocp or the new ACCI offset value because the HO condition has changed.
[0243] Currently, the most common switching type is triggered by A3 conditions, but ACCI can be applied to all types of triggers (by service gNB 110). p Decide)

[0245] Event A1 (Service becomes better than the threshold)
[0246] Event A2 (Service becomes worse than the threshold)
[0247] Event A3 (Neighbors become better than SpCell offset)
[0248] Event A4 (Neighbors become better than the threshold)
[0249] Event A5 (SpCell becomes worse than threshold 1, and its neighbors become better than threshold 2)
[0250] Event A6 (Neighbors become better than SCell offset)
[0251] Event B1 (RAT neighbors become better than the threshold)
[0252] Event B2 (PCell becomes worse than threshold 1, and RAT inter-neighbors become better than threshold 2).

[0272] This causes a change in the antenna configuration of the device, which is used to enable the device to operate as a first node in a radio telecommunications network;
[0273] This triggers the creation of the first node's antenna configuration correction or antenna configuration correction index (ACCI).
[0274] This triggers the provision of antenna configuration correction or antenna configuration correction index for the first node, which is used during beam selection to enable the first node to perform data communication.
[0275] Computer program instructions can be included in a computer program, a non-transitory computer-readable medium, a computer program product, or a machine-readable medium. In some, but not all, examples, computer program instructions may be distributed across more than one computer program.

[0315] Antenna configuration correction indexes for first nodes 110 and 120 are provided for use in beam selection process 70 to enable first nodes 110 and 120 to perform data communication.
[0316] Adjacent (non-serving) base stations 120 n In response to a request to indicate a beam, an antenna configuration correction index associated with the beam (measured by user equipment 110) is provided to serving base station 120 for use by serving base station 120 in beam selection process 70 for user equipment 110.
[0317] ACC improves the timing of handover, conditional handover, and beam management to increase throughput. ACC optimizes dwell time in a beam. ACC reduces link-level losses experienced when performing beam selection. ACCI uses only two or three bits (limited overhead). ACCI provides notification without revealing UE implementation design / secrets.
[0318] In the described example, parameter ACC can be used instead of ACCI. A potential advantage of ACCI over ACC is that it hides potentially business-sensitive details. A potential advantage of ACC over ACCI is its higher accuracy. Therefore, by using ACCI... xY Replace with ACC xY Refer to ACCI xY The examples described can also be used in ACC.
[0319] When a structural feature is described, it can be used to replace a component that performs one or more functions of the structural feature, whether or not that function or those functions are explicitly or implicitly described.
[0320] The term "module" as used here refers to a unit or device that does not include certain parts / components added by the final manufacturer or user.
[0321] The above examples use applications as supporting components for: automotive systems; telecommunications systems; electronic systems including consumer electronics; distributed computing systems; media systems for generating or rendering media content, including audio, visual, and audiovisual content, as well as mixed, mediated, virtual, and / or augmented reality; personal systems, including personal health systems or personal fitness systems; navigation systems; user interfaces, also known as human-computer interfaces; networks, including cellular, non-cellular, and fiber optic networks; self-organizing networks; the Internet of Things; the Internet of Things; virtualized networks; and related software and services.
[0322] The term “include” as used in this document has an inclusive rather than exclusive meaning. That is, any reference to X that includes Y indicates that X may include only one Y or may include more than one Y. If the intention is to use “include” with an exclusive meaning, it will be explicitly stated in the context by referring to “includes only one…” or using “consisting of…”.
[0323] In this description, references are made to various examples. Descriptions of features or functions associated with an example indicate that such features or functions exist in that example. Whether explicitly stated or not, the use of the terms "example," "for example," "may," or "may" in the text implies that such features or functions exist at least in the described example, whether or not they are described as examples, and that they may, but not necessarily, exist in some or all other examples. Therefore, "example," "for example," "may," or "may" refers to a specific instance within a class of examples. An instance's attribute can be an attribute of only that instance, an attribute of the class, or an attribute of a subclass of the class that includes some, but not all, instances within that class. Thus, it is implicitly disclosed that features described with reference to one example rather than another may be used in that other example where possible as part of a composition of work, but are not necessarily required to be used in that other example.
[0324] Although examples have been described with reference to various examples in the preceding paragraphs, it should be understood that modifications may be made to the given examples without departing from the scope of the claims.
[0325] The features described above can be used in combinations different from those explicitly described above.
[0326] Although some features have been described with reference to certain characteristics, those functions can be performed by other features, whether or not they are described.
[0327] Although features have been described with reference to some examples, those features may also exist in other examples, whether or not they are described.
[0328] The terms “a” or “that” as used in this document have an inclusive rather than exclusive meaning. That is, any application of X that includes one Y / that Y indicates that X may include only one Y or may include more than one Y, unless the context clearly indicates the opposite. If “a” or “that” is intended to have an exclusive meaning, it will be clearly stated in the context. In some cases, the use of “at least one” or “one or more” may be used to emphasize an inclusive meaning, but the absence of these terms should not be taken as an inference of any exclusive meaning.
[0329] The presence of a feature (or combination of features) in a claim is a reference to that feature or combination of features itself, and also a reference to a feature (equivalent feature) that achieves substantially the same technical effect. Equivalent features include, for example, features that are variations and achieve substantially the same result in substantially the same manner. Equivalent features include, for example, features that perform substantially the same function in substantially the same manner to achieve substantially the same result.
[0330] In this specification, adjectives or adjective phrases are used to refer to various examples to describe the characteristics of the examples. Such descriptions of characteristics associated with examples indicate that the characteristic exists exactly as described in some examples and substantially as described in others.
[0331] Although efforts have been made in the foregoing specification to draw attention to those features considered important, it should be understood that an applicant may seek protection by means of the claims for any patentable feature or combination of features mentioned above and / or shown in the figures, whether or not it has been emphasized above.
