Description

Technical Field

[0001] Some example embodiments may generally relate to mobile or wireless telecommunications systems, such as Long Term Evolution (LTE) or 5G New Radio (NR) access technologies, or 5G and above, or other communication systems. For example, some example embodiments may relate to Transmission Configuration Indicator (TCI) activation using a list of TCIs for beam management (BM) and Layer 1 / Layer 2 triggered mobility (LTM). Background Technology

[0002] Examples of mobile or wireless telecommunications systems can include Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (UTRAN), Evolved UTRAN (E-UTRAN) for Long Term Evolution (LTE), LTE-Advanced (LTE-A), MulteFire, LTE-APro, 5G or New Radio (NR) access technologies, and / or 6G radio access technologies. 5G and 6G wireless systems refer to next-generation (NG) radio systems and network architectures. 5G and 6G network technologies are primarily based on New Radio (NR) technologies, but 5G (or NG) networks can also be built on E-UTRAN radio. It is estimated that NR can provide bit rates of approximately 10-20 Gbit / s or higher and can at least support enhanced mobile broadband (eMBB) and ultra-reliable low-latency communications (URLLC) as well as massive machine-type communications (mMTC). NR is expected to provide ultra-wideband and ultra-robust, low-latency connectivity and massive networking to support the Internet of Things (IoT). Summary of the Invention

Detailed Implementation

[0017] It will be readily understood that, as generally described and illustrated in the accompanying drawings, components of certain example embodiments may be arranged and designed in a variety of different configurations. The following is a detailed description of some example embodiments of systems, methods, apparatuses, and non-transitory computer program products for beam management (BM) and Layer 1 (L1) / Layer 2 (L2) triggered mobility (LTM) activation using the same or separate TCI lists. Although the devices discussed below and illustrated in the drawings refer to 6G / 5G or next-generation NodeB (gNB) devices and UE devices, this disclosure is not limited to gNBs and UEs.

[0018] It will be readily understood that, as generally described and illustrated in the accompanying drawings, components of certain example embodiments can be arranged and designed in a variety of different configurations. Different reference numerals from the various figures may be used in the specification out of order to refer to the same elements to describe their features or functions. If desired, the different functions or processes discussed herein may be performed in different orders and / or simultaneously with each other. Furthermore, if desired, one or more of the described functions or processes may be optional or may be combined. Therefore, the following description should be considered as an illustration of the principles and teachings of certain example embodiments, and not as a limitation thereof.

[0019] The 3rd Generation Partnership Project (3GPP) provides specifications for defining inter-cell mobility based on Layer 1 (L1) and Layer 2 (L2), which may be referred to as L1 / L2 triggered mobility (LTM). Lower-layer mobility and L1 / L2 triggered mobility are used interchangeably herein. The LTM process may provide, for example, four phases: a preparation phase, an early downlink (DL) and / or uplink (UL) synchronization phase, an execution phase, and a completion phase. In the preparation phase, the Serving Centralized Unit (CU) may identify potential target cells based on Layer 3 (L3) measurement reports, prepare the target cells, and share / provide the target cell configuration with the UE. In the UL / DL synchronization phase, the Serving Distributed Unit (DU) may request or query the UE to perform timing advance (TA) acquisition for a specific target cell used for UL synchronization using, for example, L1 measurements. The DU may also trigger TCI activation for early DL synchronization and time tracking with one or more beams of the candidate target cells.

[0020] During the execution phase, the serving DU can determine or select a target cell based on L1 measurements and can request the UE to use a cell handover command to hand over to the selected target cell. The cell handover command may include, for example, the beam indication (TCI state ID) of the target cell and the TA to be used for accessing the target cell. The UE can then hand over to the target cell and begin receiving data on it. In the completion phase, the UE context can be released from the ready cell, or the UE context may not be released but can be used for dynamic handover. The CU can determine how long the UE context can be maintained.

[0021] Figure 1A and Figure 1B A signal flow diagram of one or more LTM procedures is shown. The LTM procedures can be executed by the configuration of UE 101, source DU 102, target DU 103, and CU 104. Procedures 110-121 can be preparation phases. At 110, UE 101 can provide an L3 measurement report to source DU 102, and at 111, source DU 102 can transmit a UL Radio Resource Control (RRC) message including the L3 measurement report to CU 104. At 112, CU 104 can perform an LTM candidate preparation procedure, and at 113, CU 104 can provide a UE context establishment request to target DU 103. At 114, target DU 103 can provide a UE context establishment response message to CU 104, and at 115, CU 104 can provide a UE context modification request to source DU 102.

[0022] A UE context modification request may include one or more information elements (IEs) to provide information about the TCI state to be used in LTM, which can trigger a MAC CE. Table 1 below provides examples of IEs used for UE context modification requests.

[0023]

[0024] Table 1 At 116, source DU 102 can provide a UE context modification response message to CU 104, and at 117, CU 104 can generate an RRC reconfiguration based on, for example, the measurement configuration of an L1 cell change and the configuration of a ready cell. At 118, CU 104 can transmit a DL RRC message to source DU 102, and at 119, source DU 102 can provide an RRC reconfiguration message to UE 101. At 120, UE 101 can provide an RRC reconfiguration complete message to source DU 102, and at 121, source DU 102 can transmit a UL RRC message to CU 104.

[0025] Processes 122-126 can be the early synchronization phase. At 122, UE 101, source DU 102, target DU 103, and CU 104 can perform DL synchronization with the candidate cell, and at 123, target DU 103 can provide UE 101 with a Physical Downlink Control Channel (PDCCH) command. At 124, UE 101 can provide target DU 103 with a Random Access Channel (RACH), and at 125, target DU 103 can provide CU 104 with a TA for UE 101. At 126, CU 104 can use the TA for UE 101 to respond to source DU 102.

[0026] Processes 127-134 can be execution phases. At 127, UE 101 may provide an L1 measurement report to source DU 102, and at 128, source DU 102 may decide to perform a serving cell change. At 129, source DU 102 may optionally provide UE 101 with a Media Access Control (MAC) Control Element (CE) TCI state activation message, and at 130, source UE 102 may provide UE 101 with a MAC CE triggered cell change message. The MAC CE triggered cell change message may include a TA for the target cell. At 131, if necessary, UE 101 and target DU 103 may perform a random access procedure, and at 132, UE 101 may provide target DU 103 with an RRC reconfiguration complete message. At 133, target DU 103 may transmit an ULRRC message to CU 104, and at 134, target DU 103 may provide access notification to CU 104. At point 135, CU 104 can provide a UE context release command message to source DU 102, and at point 136, source DU 102 can provide a UE context release completion message to CU 104. At point 137, source DU 102, target DU 103, and CU 104 can perform a path switch.

[0027] For intra-cell and / or inter-cell beam management (BM), each cell can provide a list of joint / DL TCI states and a list of UL TCI states when TCI states are used for DL ​​and UL of each bandwidth portion (BWP), respectively. Figure 2 An example of RRC parameters is shown for providing DL TCI status lists and / or UL TCI status lists for intra-cell and / or inter-cell BMs.

[0028] A unified TCI state framework can be used in LTM. LTM cell handover commands can indicate the TCI state of the UE's target cell. TCI state activation of LTM candidate cells can be performed before the actual cell handover is received at the UE. TCI state activation can be performed using a MAC CE command for one or more TCI states associated with one or more candidate cells; this MAC CE command may be referred to as the Candidate Cell TCI State Activation / Deactivation MAC CE. Early TCI activation can support triggering the UE to begin fine-grained DL time / frequency synchronization with a given TCI state of a candidate cell. This can be used to prepare the UE for LTM cell handover and can achieve shorter interruptions during cell handover, which may not necessarily require time tracking of the target TCI state. Cell handover can occur within a short time frame after early candidate cell TCI state activation, and the network can perform early activation only on candidate cells that can be the target cell.

[0029] When performing early TCI activation, the cell handover command may include, for example, one of the activated TCI states as an indication of the TCI state associated with the target cell, which the UE can use to send or receive DL / UL channels / signals from the target cell. If TCI activation is not performed before the cell handover, the cell handover command may activate and indicate the target TCI state. To implement TCI activation and indication for LTM, each candidate cell / DU may provide a list of TCI states to the serving cell / DU via the CU. The TCI state list for each candidate cell (which may be referred to as the candidate TCI state list or LTM TCI state list) may be provided to the UE in LTM configuration within each candidate cell configuration, in addition to the ServingCellConfig of the candidate cell configuration.

[0030] Figure 3 An example of RRC parameters used to provide joint / DL TCI status and / or UL TCI status for LTM is shown. When the UE receives an RRC reconfiguration that may include LTM configuration before receiving a cell handover command, the UE can decode the TCI status list. When performing early TCI activation, and the UE has more than one active TCI status besides the TCI status indicated in the cell handover command at the time of cell handover, the UE can be configured to retain the active TCI status after the cell handover. The active TCI status can be used for subsequent LTM and / or target cell BM.

[0031] To perform an LTM cell handover, a UE can be configured with one or more active TCI states and can indicate at least one of the TCI states in the LTM cell handover command used for the handover. The UE can use the indicated TCI state to transmit at least uplink messages, such as an RRC reconfiguration complete message. The TCI states used for LTM cell handover may be referred to as candidate or LTM TCI states. For a cell, the UE can use two separate lists of TCI states, such as a candidate / LTMTCI state list and a BM TCI state list.

[0032] Various example embodiments can provide technical advantages to implement one or more processes that enable the use of TCI states configured separately for LTM and BM in separate lists. Some example embodiments can provide solutions for situations where it is impossible or undesirable to use or manage the LTM TCI state of a target cell due to processing and / or memory complexity. Signaling and actions may need to be defined for the UE and network elements (such as, for example, DUs providing one or more LTM candidate cells) to avoid ambiguity regarding the TCI state activated after cell handover for LTM and / or BM on the target cell.

[0033] Some example embodiments may provide a network entity (NW) that can configure the UE to use the indicated TCI state only for LTM TCI states or for both LTM and BM TCI states. The UE may indicate whether it supports the same configuration for the LTM TCI state list and the BM TCI state list for the candidate cell, which may be associated with the BWP to be used for LTM. The same configuration may include, for example, the same TCI state ID, the same number of TCI states, and / or configuration parameters regarding quasi-co-location (QCL) information. Based on the UE's capabilities, the CU may request each candidate DU to provide an LTM TCI state list. Each candidate DU may provide the same configuration for LTM and BM TCI states, or may provide different configurations for LTM and BM TCI states with different TCI state IDs, the same number of TCI states, and / or different QCL information parameters.

[0034] Some example embodiments may provide that, in the LTM configuration, a common configuration parameter can be indicated to the UE. This common configuration parameter may be an indication of the same or different TCI state configurations for LTM and BM across all candidate cells, or it may be a separate configuration parameter for each candidate cell, which may also be an indication of the same or different TCI state configurations for LTM and BM. When the same configuration exists for LTM TCI states and BM TCI states, after cell handover, one or more LTM TCI states of the target cell can be mapped to BM TCI states using the TCI state ID, which can be prepared for BM TCI activation and / or indication. When different configurations exist for LTM and BM TCI states, the UE may assume that one or more LTM TCI states cannot be mapped to BM TCI states. The indicated LTM beam can be used until the UE receives new BM TCI activation and indication, and it is assumed that other active LTM TCI states of the target cell (if any) are at least deactivated for BM.

[0035] Various example embodiments may provide one or more procedures to be performed by the UE. The UE may indicate in a message (such as, for example, in an RRC message) whether it supports the same configuration for TCI states for LTM and BM, or separate / different configurations. When the UE has not yet indicated support or non-support for the same TCI state configuration for LTM and BM, or has indicated support for different TCI state configurations for LTM and BM, the UE may determine that after cell handover, upon receiving an LTM configuration indicating a list of TCI states for BM and LTM for a specific cell, the UE may not assume that any TCI state for BM is activated based on LTM TCI state activation. Additionally or alternatively, the UE may assume that LTM TCI states are activated and / or that activation is retained. Furthermore, for LTM purposes, the UE may determine to activate activated TCI states after cell handover. Alternatively, the UE may determine to deactivate activated TCI states after cell handover for LTM purposes.

[0036] Some example implementations may provide a situation where the UE has indicated support for the same configuration of TCI states for LTM and BM, or the UE actually supports the same configuration of TCI states for LTM and BM. In examples, the UE may indicate support in various forms; for example, not indicating support (e.g., not providing the network with information about the UE supporting the same TCI list) may indicate that the UE does not support the same TCI state list. In another example, the UE may indicate support for the same or different lists for LTM and BM. Upon receiving an LTM configuration indicating the same TCI state list for BM and LTM for a specific cell, the UE may determine that after cell handover, one or more active TCI states for LTM (e.g., before cell handover) may be active TCI states for BM (e.g., if the UE has already indicated support for the same list). Furthermore, for LTM purposes, the UE may determine to activate the active TCI states after cell handover. Alternatively, the UE may determine to deactivate the active TCI states after cell handover for LTM purposes.

[0037] Some example embodiments may provide one or more procedures to be performed by a network entity such as a CU. The CU may receive an indication of whether the UE supports the same configuration for both the LTM and BM TCI state lists or a separate configuration. For example, this indication may be received as part of a UE capability container. Some example embodiments may provide that, based on the UE capabilities, the CU may request another network entity (such as a DU) hosting the target cell to provide the LTM TCI state accordingly. The same configuration for both the LTM and BM TCI states or different configurations for the LTM and BM TCI states may be provided. Various example embodiments may provide common configuration parameters across all candidate cells or separate configuration parameters for each candidate cell.

[0038] Various example embodiments may provide one or more procedures to be performed by another network entity, such as a DU. The DU (e.g., a candidate DU) may receive the UE's capabilities via the CU. Based on the UE's capabilities, the DU may provide a list of LTM TCI states for LTM and BM. For example, if the UE supports the same configuration, the DU may confirm that the LTM TCI state list and the BM TCI state list belong to the same list, such as, for example, candidate TCI state ID 1 for LTM = TCI state ID 1 for BM. Similarly, if the UE does not support the same configuration, the DU may provide a different LTM TCI state list than the BM TCI state list, such as, for example, TCI state ID 1 for LTM ≠ TCI state ID 1 for BM.

[0039] Some example embodiments may provide the DU with information on the active TCI state for LTM (e.g., TCI state ID) and / or an indication of the indicated TCI state for cell handover. For a handover UE, when the DU has received an indication that it supports the same list of TCI states for both LTM and BM, and / or when the DU provides the same configuration of TCI states for both LTM and BM, the DU may determine that the UE has activated a TCI state for BM based on the activation of the LTM TCI state after the cell handover is complete. Additionally, for LTM purposes, the DU may determine to activate the active TCI state after the cell handover. Alternatively, the DU may determine to deactivate the activated TCI state after the cell handover for LTM purposes.

[0040] Some example embodiments may provide that the DU can receive configurations of active TCI states for LTM and / or indications of indicated TCI states for cell handover. For a handover UE, when the DU does not receive an indication that it supports the same list of TCI states for LTM and BM, or when the UE supports separate lists of TCI states, and / or when the DU provides different configurations of TCI states for LTM and BM, the DU may determine, after cell handover completion, that the UE has not yet activated a TCI state for BM based on the activation of the LTM TCI state. The DU may determine that the UE has an active and indicated TCI state for BM, which may be the TCI state indicated in the cell handover command. Additionally, for LTM purposes, the DU may determine that the active TCI state is activated after cell handover. Alternatively, the DU may determine that the active TCI state is deactivated after cell handover for LTM purposes.

[0041] Some example implementations may provide that the same TCI state configuration can provide a TCI state list for LTM and BM for a particular cell, where at least the TCI state ID, the number of TCI states in the TCI state list, and / or the QCL information and reference signals included in the TCI state list can be the same.

[0042] Figure 4A and Figure 4B Examples of signal flow diagrams for managing LTM and BM TCI states according to various example embodiments are shown. The UE may indicate the ability to support the same configuration for LTM and BM TCI states. Based on this indication from the UE, an LTM TCI state can be prepared and provided to the UE, and then the active LTM TCI state can be mapped to the active BM TCI state after cell handover.

[0043] Some example embodiments may provide a method that includes, at 410, assuming UE 401 is connected to source DU 402. The UE may indicate that it has the capability to have the same configuration for LTM and BM TCI states. At 411, UE 401 may provide measurement reports to source DU 402 and CU 403, and at 412, CU 403 may perform a handover (HO) decision. At 413, CU 403 may provide a UE context establishment request to one or more candidate target DUs (such as candidate target DU 404). The UE context establishment request may include, for example, flags or other indications for the same configuration for LTM and BM TCI states. At 414, candidate target DU 404 may provide a UE context establishment response message to CU 403. The UE context establishment response message may include the LTM configuration and the LTM TCI state having the same configuration in BM.

[0044] At 415, CU 403 may provide a UE context modification request to source DU 402, and at 416, source DU 402 may respond to the request using a UE context modification response message. At 417, CU 403 may generate an RRC reconfiguration for LTM preparation. The RRC reconfiguration may include flags or indications for the same configuration for LTM and BM TCI states. At 418, CU 403 may provide the generated RRC reconfiguration to source DU 402 and / or UE 401, and at 419, UE 401 may provide an RRC reconfiguration completion message to source DU 402 and / or CU 403. At 420, UE 401 may provide an L1 measurement report to source DU 402, and at 421, source DU 402 may respond with MAC CE TCI activation for the LTM TCI state (e.g., TCI state 1-3) of candidate target DU 404. At 422, UE 401 may activate a TCI state (e.g., TCI state 1-2), and at 423, early TA acquisition may be performed among one or more of UE 401, source DU 402, CU 403 and / or candidate target DU 404.

[0045] At 424, UE 401 can provide an L1 measurement report to source DU 402, and at 425, source DU 402 can decide to perform a serving cell change, such as selecting cell 2 and TCI state 2. At 426, source DU 402 can provide UE 401 with a MAC CE cell handover command. The MAC CE cell handover command may include, for example, indications of TCI state 2, cell 2, and TA. At 427, source DU 402 can provide candidate target DU 404 with the active LTM TCI state of the cell (e.g., cell 2) and the indicated TCI state. At 428, UE 401 can provide candidate target DU 404 with an RRC reconfiguration complete message, and at 429, the cell handover can be completed, and UE 401 can connect to candidate target DU 404. At 430, UE401 can target the LTM TCI state of the BM-activated cell (e.g., cell 2), and at 431, candidate target DU 404 can target the LTM TCI state of the BM-activated cell (e.g., cell 2).

[0046] In some example embodiments where the UE indicates that it cannot support the same configuration of LTM and BM, or where the UE indicates that it can support different configurations of LTM and BM, a similar process as shown in Figure 4 can be applied. The NW (such as the CU and / or DU) can consider and configure the same or different configurations of LTM and BM TCI states, and can indicate this to the UE accordingly.
