Abstract

A method includes transmitting a RAN profile indexing message from a cell to a user equipment (UE) within the cell'"'"'s radio coverage, the RAN profile indexing message comprising a plurality of sets of RAN parameters corresponding to a plurality of physical layer configurations, and a plurality of indices corresponding to the plurality of sets of RAN parameters. The method also includes transmitting a downlink control information message to the UE indicating a resource block allocated for the UE, and an index corresponding to one of the plurality of sets of RAN parameters. The method further includes performing a RAN profile indexing operation to define the plurality of sets of RAN parameters corresponding to a plurality of physical layer configurations, and assigning the plurality of indices to the plurality of sets of RAN parameters.

transmitting, by the cell, a downlink control information (DCI) message to the UE indicating a resource block (RB) allocated for the UE, and an index corresponding to one of the plurality of sets of RAN parameters.

2. The method of claim 1, further comprising:

performing, by the cell, a RAN profile indexing operation to define the plurality of sets of RAN parameters corresponding to the plurality of physical layer configurations; and

assigning, by the cell, the plurality of indices to the plurality of RAN parameters.

3. The method of claim 1, further comprising:

receiving, by the cell, a confirm message from the UE indicating at least one of the plurality of indices that the UE does not support.

4. The method of claim 1, further comprising:

receiving, by the cell, an acknowledge message from the UE indicating that the UE supports all of the plurality of indices after transmitting the RAN profile indexing message.

5. The method of claim 3, wherein the transmitting, by the cell, the DCI message to the UE is based on the confirm message received from the UE.

6. The method of claim 3, further comprising:

re-configuring, by the cell, the plurality of sets of RAN parameters and the corresponding plurality of indices based on the confirm message; and

transmitting a radio resource control (RRC) message to the UE indicating changes to the plurality of sets of RAN parameters and the corresponding plurality of indices;

wherein the changes to the plurality of sets of RAN parameters and the corresponding plurality of indices further comprise at least one of adding a new index for a new set of RAN parameters, removing an existing index, modifying one of the plurality of sets of RAN parameters, and canceling at least one of the plurality of indices.

7. The method of claim 1, further comprising:

counting, by the cell, a predefined time interval after transmitting the RAN profile indexing message to the UE, wherein during the predefined time interval, the cell maintains the plurality of sets of RAN parameters and the corresponding plurality of indices.

8. The method of claim 7, further comprising:

re-configuring, by the cell, after an expiration of the predefined time interval, the plurality of sets of RAN parameters and the corresponding plurality of indices; and

transmitting an RRC message to the UE indicating the re-configured plurality of sets of RAN parameters and the corresponding plurality of indices.

9. The method of claim 1, wherein the cell broadcasts the RAN profile indexing message using a system information (SI) message.

10. The method of claim 1, wherein the cell broadcasts the RAN profile indexing message periodically using a broadcasting channel (BCH).

11. The method of claim 1, wherein the cell signals the RAN profile indexing message to the UE using a unicast RRC message.

12. The method of claim 11, wherein the cell signals the RAN profile indexing message to the UE upon receiving a request.
