Scheduling transmissions on channels in a wireless network
Allocation of resources in a wireless network are described where resources are allocated for each channel having a second parameter above zero prior to another channel for transmission having a third parameter less than or equal to zero. The second parameter may be derived from a first channel's first parameter and the third parameter is derived from a second channel's first parameter.
1. A user equipment (UE) comprising:
a transmitter and circuitry configured to receive; and
a processor communicatively coupled to the transmitter and the circuitry configured to receive, wherein the processor is configured to:
cause the circuitry to receive weight 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 respective 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 data are selected from a subset of the plurality of radio bearers based on the received weight parameters,
wherein in the second iteration, the data are selected based on buffered data for respective radio bearers, and
cause the transmitter to transmit a signal including the selected data using the single allocation of uplink resources.
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, at least in part, 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. The UE of claim 1 , wherein the processor is further configured to cause the circuitry to receive the weight parameters associated with the plurality of radio bearers upon initial connection to the network.
9. The UE of claim 1 , wherein the processor is further configured to cause the circuitry to receive updates to the weight parameters associated with the plurality of radio bearers.
10. The UE of claim 9 , wherein the processor is further configured to cause the circuitry to receive updates to the weight parameters associated with the plurality of radio bearers via a radio bearer reconfiguration message.
11. A method performed by a user equipment (UE), the method comprising:
receiving, by the UE, weight 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 data are selected from a subset of the plurality of radio bearers based on the received weight parameters;
wherein in the second iteration, the data are selected based on buffered data for respective radio bearers; and
transmitting, by the transmitter, a signal including the selected data using the single allocation of uplink resources.
12. The method of claim 11 , wherein the plurality of radio bearers are associated with a plurality of channels.
13. The method of claim 11 , wherein each radio bearer of the plurality of radio bearers is associated with at least one data flow or IP flow.

15. The method of claim 11 , wherein the plurality of radio bearers are associated with at least one packet data protocol (PDP) context.
16. The method of claim 11 , wherein the single allocation of uplink resources is received on a physical shared channel from a scheduler in the network.
17. The method of claim 11 , wherein the subset of the plurality of radio bearers is associated with a Quality of Service (QoS).
18. The method of claim 11 , wherein receiving the weight parameters associated with the plurality of radio bearers occurs upon initial connection to the network.
19. The method of claim 11 , further comprising receiving updates to the weight parameters associated with the plurality of radio bearers.
