Abstract
In one embodiment, a message is sent from the wireless network to a user equipment having a variable rate vocoder. The message defines transport block sizes for the user equipment to select from in making uplink transmissions if the user equipment is permitted to vary a packet size for uplink transmission. A scheduling grant is sent to the user equipment, and the scheduling grant includes an indicator indicating that the user equipment is permitted to vary the packet size for uplink transmissions by selecting a transport block size from among the defined transport block sizes.
Claims16
A method, comprising:
- sending a message to a user equipment having a variable rate vocoder,
- the message defining two or more transport block sizes for the user equipment to select from in making uplink transmissions if the user equipment is permitted to vary a packet size for uplink transmissions during a talk spurt;
- and
- sending a scheduling grant to the user equipment,
- the scheduling grant including an indicator indicating that the user equipment is permitted to vary the packet size for uplink transmissions during a talk spurt, and autonomously select and use a transport block size from among the defined transport block sizes during the talk spurt,
- wherein the indicator indicates that the user equipment is to select a smallest of the defined transport block sizes that permits delivery of data in a buffer of the user equipment.
A method, comprising:
- receiving, at user equipment having a variable rate vocoder, a message defining two or more transport block sizes for the user equipment to select from in making uplink transmissions if the user equipment is permitted to vary a packet size for uplink transmissions during a talk spurt;
- and
- receiving, at the user equipment, a scheduling grant, the scheduling grant including an indicator indicating that the user equipment is permitted to vary the packet size for uplink transmissions during a talk spurt by selecting a transport block size from among the defined transport block sizes;
- and
- selecting, at the user equipment, a transport block size from among the defined transport block sizes if the indicator indicates that the user equipment is permitted to vary the packet size for uplink transmissions during a talk spurt by autonomously selecting and using a transport block size from among the defined transport block sizes during the talk spurt, the user equipment selecting a smallest of the defined transport block sizes that permits delivery of data in a buffer of the user equipment;
- and
- transmitting a packet on the uplink based on the selected transport block size.
