Determining buffer occupancy and selecting data for transmission on a radio bearer

1. A user equipment (UE) comprising:

a processor communicatively coupled to a transmitter and circuitry configured to receive; and

the processor is configured to:

cause the circuitry to receive parameters associated with a plurality of radio bearers,

determine a plurality of buffer occupancies, wherein each of the plurality of buffer occupancies is associated with one or more radio bearers of the plurality of radio bearers,

cause the transmitter to transmit a message including the plurality of buffer occupancies to a network,

cause the circuitry to receive a single allocation of uplink resources,

select data from the plurality of radio bearers for transmission using the single allocation of uplink resources, wherein the selection of the data occurs using a first iteration and a second iteration,

wherein in the first iteration, the selection of the data is selected from a subset of the plurality of radio bearers based on the received parameters,

wherein in the second iteration, the selection of the data is based on buffered data for respective radio bearers, and

cause the transmitter to transmit a signal including the selected data.

2. The UE of claim 1 , wherein the plurality of radio bearers are associated with a plurality of channels.

3. The UE of claim 1 , wherein each radio bearer of the plurality of radio bearers is associated with at least one data flow or IP flow.

4. The UE of claim 1 , wherein the selected data is selected based on a priority or a Quality of Service (QoS).

5. The UE of claim 1 , wherein the plurality of radio bearers are associated with at least one packet data protocol (PDP) context.

6. The UE of claim 1 , wherein the single allocation of uplink resources is received on a physical shared channel from a scheduler in the network.

7. The UE of claim 1 , wherein the subset of the plurality of radio bearers is associated with a Quality of Service (QoS).

8. A method performed by a user equipment (UE), the method comprising:

receiving, by the UE, parameters associated with a plurality of radio bearers;

determining, by a processor of the UE, a plurality of buffer occupancies, wherein each of the plurality of buffer occupancies is associated with one or more radio bearers of the plurality of radio bearers;

transmitting, by a transmitter of the UE, a message including the plurality of buffer occupancies to a network;

receiving, by the UE, a single allocation of uplink resources;

selecting, by the processor, data from the plurality of radio bearers for transmission using the single allocation of uplink resources, wherein the selection of the data occurs using a first iteration and a second iteration;

wherein in the first iteration, the selection of the data is selected from a subset of the plurality of radio bearers based on the received parameters;

wherein in the second iteration, the selection of the data is based on buffered data for respective radio bearers; and

transmitting, by the transmitter, a signal including the selected data.

9. The method of claim 8 , wherein the plurality of radio bearers are associated with a plurality of channels.

10. The method of claim 8 , wherein each radio bearer of the plurality of radio bearers is associated with at least one data flow or IP flow.

11. The method of claim 8 , wherein the selected data is selected based on a priority or a Quality of Service (QoS).

12. The method of claim 8 , wherein the plurality of radio bearers are associated with at least one packet data protocol (PDP) context.

13. The method of claim 8 , wherein the single allocation of uplink resources is received on a physical shared channel from a scheduler in the network.

14. The method of claim 8 , wherein the subset of the plurality of radio bearers is associated with a Quality of Service (QoS).
