Regarding claim 151, The method of claim 143, , wherein the apparatus is pre-configured or pre-indicated via radio resource control (RRC) signaling of a configured serving cell not activated for data or control, and wherein the configured serving cell is the candidate cell or an additional candidate cell.
Kung [0245] In NR, a UE may perform a handover (HO) procedure to switch from one cell to another cell. The UE may perform the handover procedure in response to a Radio Resource Control (RRC) signaling transmitted by a network. The RRC signaling may comprise cell information of a target cell.
[0369] With respect to one or more embodiments herein, the second cell may be a serving cell. Alternatively and/or additionally, the second cell may be a deactivated cell or an activated cell.
Kung does not teach radio resource control (RRC) signaling with one or more beams for different channels or reference signals.
Rune teaches radio resource control (RRC) signaling with one or more beams for different channels or reference signals.
Rune [0121] When beam sweeping is used in conjunction with handover (or any mobility procedure), the wireless device has an active control signaling connection (typically an RRC connection) to its serving access node (or via its serving access node to a controlling entity that is separate from the serving access node). Before a beam sweep in conjunction with handover, the wireless device can be configured via RRC for the beam sweep (e.g. in terms of which reference signals to listen for in the beams, what and how to report the result).
In view of Rune, Kung is modified such that the radio resource control (RRC) signaling with one or more beams for different channels or reference signals.
Kung and Rune are analogous art to the claimed invention because they are in the same field of
endeavor, a system of handover.
It would be obvious before the effective filing date of claimed invention, to a person of ordinary skill in
the art to modify Kung in a manner described above to include one or more beams for different reference signals in the RRC for the UE to decide which reference signal and the beams it listen to (Rune [0121]).
Claims 142, 152 are rejected under 35 U.S.C. 103 as being unpatentable over Kung in view of Gao et al. (US 20230180093 A1)(“Gao”).
Regarding claim 142, The apparatus of claim 133, wherein the at least one processor is configured to: receive a Transmission Configuration Indicator (TCI) activation MAC-CE,
Kung [0260] Alternatively and/or additionally, the second information may be (and/or may be transmitted in) a signaling indicative of an activation of one or more TCI states (e.g., the signaling may comprise a TCI and/or Sounding Reference Signal (SRS) activation MAC Control Element (CE)) for one or more channels
wherein the TCI activation MAC-CE activates a TCI state configured for a candidate cell not selected for use to
Kung [0345]; For example, the signaling may indicate (and/or instruct) initiation of the procedure. The signaling may be transmitted via PDCCH and/or the signaling may be a DCI. Alternatively and/or additionally, the signaling may be a MAC CE. The signaling may comprise TCI state activation and/or deactivation information (e.g., uplink and/or downlink TCI state activation and/or deactivation information) of the Target Cell 904.
Kung [0247]; The UE may consider the second cell to be a Special Cell (SpCell), or a target cell (and/or a target SpCell) of the UE based on the second information (and/or in response to receiving the second information).
Kung [0369] Alternatively and/or additionally, the second cell may be a deactivated cell or an activated cell.
Reducing latency after the apparatus starts to communicate with the candidate cell.
Kung [0245] In NR, a UE may perform a handover (HO) procedure to switch from one cell to another cell. The UE may perform the handover procedure in response to a Radio Resource Control (RRC) signaling transmitted by a network. The RRC signaling may comprise cell information of a target cell. The network determines to initiate the handover procedure based on one or more measurement reports of the UE. Switching between cells may take place more frequently when a UE is operating and/or performing communication in a frequency range, such as FR2 (e.g., 24.25 GHz to 52.6 GHz). Based on work item description (WID) of further enhancements of MIMO in RP-193133 New WID, inter-cell mobility considering Layer-1 and/or Layer-2 solution may reduce latency of the handover procedures.
