Abstract

A wireless communication device is described. The wireless communication device includes a receiver configured to receive a message indicating a transmission configuration indicator (TCI) state. The wireless communication device also includes a processor configured to determine the TCI state based on the message, a non-serving cell identifier, and a received reference signal from a non-serving cell.

Claims (33)

1 . A wireless communication device, comprising:

a communications interface; and

a processor coupled to the communications interface, wherein the wireless communication device is configured to:

transmit transmission configuration indicator (TCI) state capability information, wherein the TCI state capability information indicates a maximum number of TCI states for serving cells and non-serving cells, and wherein a monitoring set of reference signals corresponding to one or more non-serving cells is based on a frequency range of serving cell reference signals and a capability of the wireless communication device.

2 . The wireless communication device of claim 1 , wherein a first TCI state identifier numbering space for serving cells is separate from a second TCI state identifier numbering space for non-serving cells.

3 . The wireless communication device of claim 1 , wherein a TCI state identifier numbering space is shared for serving cells and non-serving cells.

4 . The wireless communication device of claim 1 , wherein the wireless communication device is configured to determine a qualified set of reference signals based on the monitoring set of reference signals.

5 . The wireless communication device of claim 1 , wherein the monitoring set of reference signals for sub-layer 3 mobility corresponding to the one or more non-serving cells is based on a received set of reference signal identifiers.

6 . The wireless communication device of claim 1 , wherein the monitoring set of reference signals is based on a serving cell TCI state.

7 . The wireless communication device of claim 1 , wherein the wireless communication device is configured to determine a qualified set of reference signals based on a first TCI state corresponding to a particular serving cell.

8 . A wireless communication device, comprising:

a communications interface; and

a processor coupled to the communications interface, wherein the wireless communication device is configured to:

transmit transmission configuration indicator (TCI) state capability information, wherein the TCI state capability information indicates a maximum number of TCI states for serving cells and non-serving cells; and

determine a qualified set of reference signals based on a frequency range of serving cell reference signals and a capability of the wireless communication device.

9 . A wireless communication device, comprising:

a communications interface; and

a processor coupled to the communications interface, wherein the wireless communication device is configured to:

transmit transmission configuration indicator (TCI) state capability information, wherein the TCI state capability information indicates a maximum number of non-serving cells with reference signals configured for TCI state association.

10 . A wireless communication device, comprising:

a communications interface; and

a processor coupled to the communications interface, wherein the wireless communication device is configured to:

transmit transmission configuration indicator (TCI) state capability information, wherein the TCI state capability information indicates a maximum number of physical cell identifiers (PCIs) of cells, other than a serving cell, that are associated with activated TCI states.

11 . A wireless communication device, comprising:

a communications interface; and

a processor coupled to the communications interface, wherein the wireless communication device is configured to:

determine a TCI state based on a TCI state message, a non-serving cell identifier, and a reference signal corresponding to a non-serving cell, wherein the TCI state message includes quasi-colocation (QCL) information corresponding to non-serving cell information without serving cell information; and

perform one or more operations based on the TCI state.

12 . A wireless communication device, comprising:

a communications interface; and

a processor coupled to the communications interface, wherein the wireless communication device is configured to:

determine a TCI state based on a TCI state message and a non-serving cell identifier, wherein all quasi-colocation (QCL) information in the TCI state message corresponds to reference signals that correspond to a single non-serving cell; and

perform one or more operations based on the TCI state.
