Abstract

The present application relates to devices and components including apparatus, systems, and methods for cross-cell indication of radio network temporary identifiers or mobility based on bandwidth part switching.

Claims (35)

1 . An apparatus comprising:

processor circuitry to:

generate a measurement object (MO) configuration to be transmitted to a user equipment (UE) to configure the UE for neighbor cell measurements, the MO configuration having a list of a physical cell identities (PCIs);

generate first configuration information to be transmitted to the UE via a serving cell to configure a first bandwidth part (BWP) of the serving cell;

generate second configuration information to be transmitted to the UE to configure a second BWP of a neighbor cell, the second configuration information to include a first index to associate the second BWP with a first PCI of the list of PCIs; and

generate an indication of a transmission configuration indicator (TCI) state associated with the second BWP, the indication to be transmitted to the UE to handover service of the UE from the first BWP of the serving cell to the second BWP of the neighbor cell; and

interface circuitry, coupled with the processor circuitry, to transmit the MO configuration, the first configuration information, and the second configuration information.

2 . The apparatus of claim 1 , wherein the

MO configuration is a measurement object new radio (MeasObjectNR) information element (IE).

3 . The apparatus of claim 1 , wherein the first BWP and the second BWP include common radio resource control (RRC) parameters, the common RRC parameters to include a subcarrier spacing, cyclic prefix type, or one or more parameters in a BWP downlink or uplink common configuration.

4 . The apparatus of claim 1 , wherein the processor circuitry is to:

generate information to be transmitted to the UE to configure the UE with a plurality of BWPs with a same identifier in different component carriers in a band or band group, wherein the plurality of BWPs are to be associated with a same PCI.

5 . The apparatus of claim 1 , wherein the second BWP is in a band or band group with a primary serving cell or a primary secondary serving cell.

6 . The apparatus of claim 1 , wherein the second BWP is an initial BWP.

7 . The apparatus of claim 6 , wherein the initial BWP is an initial uplink BWP or an initial downlink BWP.

8 . A method comprising:

generating a measurement object (MO) configuration to be transmitted to a user equipment (UE) to configure the UE for neighbor cell measurements, the MO configuration having a list of a physical cell identities (PCIs);

generating first configuration information to be transmitted to the UE via a serving cell to configure a first bandwidth part (BWP) of the serving cell;

generating second configuration information to be transmitted to the UE to configure a second BWP of a neighbor cell, the second configuration information to include a first index to associate the second BWP with a first PCI of the list of PCIs; and

generating an indication of a transmission configuration indicator (TCI) state associated with the second BWP, the indication to be transmitted to the UE to handover service of the UE from the first BWP of the serving cell to the second BWP of the neighbor cell.

9 . The method of claim 8 , wherein the first BWP and the second BWP include common radio resource control (RRC) parameters, the common RRC parameters to include a subcarrier spacing, cyclic prefix type, or one or more parameters in a BWP downlink or uplink common configuration.

10 . A method comprising:

receiving, via a serving cell, a measurement object (MO) configuration having a list of a physical cell identities (PCIs), the MO configuration to configure neighbor cell measurements;

receiving, via the serving cell, first configuration information to configure a first bandwidth part (BWP) of the serving cell;

receiving second configuration information to configure a second BWP of a neighbor cell, the second configuration information to include a first index to associate the second BWP with a first PCI of the list of PCIs;

receiving an indication of a transmission configuration indicator (TCI) state associated with the second BWP; and

performing, based on receiving the indication, a handover of service from the first BWP of the serving cell to the second BWP of the neighbor cell.

11 . The method of claim 10 ,

wherein the MO configuration is a measurement object new radio (MeasObjectNR) information element (IE).

12 . The method of claim 10 , wherein the first BWP and the second BWP include common radio resource control (RRC) parameters, the common RRC parameters to include a subcarrier spacing, cyclic prefix type, or one or more parameters in a BWP downlink or uplink common configuration.

13 . The method of claim 10 , further comprising:

receiving information to configure a plurality of BWPs with a same identifier in different component carriers in a band or band group, wherein the plurality of BWPs are to be associated with a same PCI.

14 . The method of claim 10 , wherein the second BWP is in a band or band group with a primary serving cell or a primary secondary serving cell.

15 . The method of claim 10 , wherein the second BWP is an initial BWP.

16 . The method of claim 15 , wherein the initial BWP is an initial uplink BWP or an initial downlink BWP.
