Abstract

A method and apparatus for multiplexing are disclosed. Data is received over a plurality of logical channels. Data from the plurality of logical channels is multiplexed into a medium access control (MAC) protocol data unit (PDU) based on a priority associated with each of the plurality of the logical channels. The MAC PDU is transmitted over an uplink transport channel.

First claim

The invention claimed is:

1. A method comprising:
receiving data over a plurality of logical channels with a receiving element, each logical channel being associated with a Quality of Service (QoS) requirement;
establishing an allowed data rate for each of the plurality of logical channels for the multiplexing of data:
multiplexing data from the plurality of logical channels into an enhanced medium access control (MAC-e) protocol data unit (PDU) based on a priority associated with each of the plurality of the logical channels, wherein the multiplexing is to maintain the QoS requirements of the logical channels; and
transmitting the MAC-e PDU over an uplink transport channel with a transmitting element.

2. The method of claim 1 , wherein the data from the plurality of logical channels is multiplexed based on both the allowed data rate and the priority associated with each of the plurality of logical channels.

3. The method of claim 1 , wherein the data from the plurality of logical channels is multiplexed utilizing absolute priority of the logical channels, data from a logical channel associated with a highest priority being multiplexed first up to the allowed data rate associated with the highest priority logical channel before data from other logical channels is multiplexed.

4. The method of claim 1 , wherein the data from the plurality of logical channels is multiplexed utilizing absolute priority of the logical channels, data from a logical channel associated with a higher priority being multiplexed up to its allowed data rate before data from a logical channel associated with a lower priority is multiplexed.

5. The method of claim 1 , wherein the allowed data rate is received from a radio network.

6. A wireless transmit/receive unit (WTRU) comprising:
a receiver to receive data over a plurality of logical channels, each logical channel being associated with a Quality of Service (QoS) requirement;
a multiplexor to multiplex data from the plurality of logical channels into an enhanced medium access control (MAC-e) protocol data unit (PDU) based on a priority associated with each of the plurality of the logical channels, wherein an allowed data rate is established for each of the plurality of logical channels for the multiplexing of data, and wherein the multiplexing is to maintain the QoS requirements of the logical channels; and
a transmitter to transmit the MAC-e PDU over an uplink transport channel.

7. The WTRU of claim 6 , wherein the multiplexer is to multiplex the data from the plurality of logical channels based on both the allowed data rate and the priority associated with each of the plurality of logical channels.

8. The WTRU of claim 6 , wherein the data from the plurality of logical channels is multiplexed utilizing absolute priority of the logical channels, the multiplexer to multiplex data from a logical channel associated with a highest priority first up to the allowed data rate associated with the highest priority logical channel before data from other logical channels is multiplexed.

9. The WTRU of claim 6 , wherein the data from the plurality of logical channels is multiplexed utilizing absolute priority of the logical channels, the multiplexer to multiplex data from a logical channel associated with a higher priority up to its allowed data rate before data from a logical channel associated with a lower priority is multiplexed.

10. The WTRU of claim 6 , wherein the allowed data rate is to be received from a radio network.

11. A method for multiplexing data comprising:
receiving configuration information from a wireless network by a receiver, wherein the configuration information indicates a priority of each logical channel of a plurality of logical channels, each logical channel being associated with a Quality of Service (QoS) requirement;
determining a data size based on the configuration information;
multiplexing data of the logical channels into an enhanced medium access control (MAC-e) protocol data unit (PDU) based on the priority and the determined data size, wherein the multiplexing is to maintain the QoS requirements of the logical channels, wherein multiplexing data of the logical channels includes multiplexing data from a highest priority logical channel to a lowest priority logical channel; and
transmitting the MAC-e PDU to the wireless network by a transmitter.

12. The method of claim 11 , wherein the data from the plurality of logical channels is multiplexed utilizing absolute priority of the logical channels, multiplexing data of the logical channels including multiplexing data of a highest priority logical channel based on the determined data size prior to multiplexing a next highest priority logical channel.

13. A wireless transmit/receive unit (WTRU) comprising:
means for receiving configuration information from a wireless network, wherein the configuration information indicates a priority of each logical channel of a plurality of logical channels, each logical channel being associated with a Quality of Service (QoS) requirement;
means for determining a data size based on the configuration information;
means for multiplexing data of the logical channels into an enhanced medium access control (MAC-e) protocol data unit (PDU) based on the priority and the determined data size, wherein the multiplexing is to maintain the QoS requirements of the logical channels, wherein the means for multiplexing data is to multiplex the data of the logical channels from a highest priority logical channel to a lowest priority logical channel; and
means for transmitting the MAC-e PDU to the wireless network.

14. The WTRU of claim 13 , wherein the data from the plurality of logical channels is multiplexed utilizing absolute priority of the logical channels, the means for multiplexing data to multiplex the data of a highest priority logical channel based on the determined data size prior to multiplexing a next highest priority logical channel.

15. A method comprising:
receiving data over a plurality of logical channels with a receiving element, each logical channel being associated with a Quality of Service (QoS) requirement;
multiplexing data from the plurality of logical channels into an enhanced medium access control (MAC-e) protocol data unit (PDU) based on a priority associated with each of the plurality of the logical channels, wherein the multiplexing is to maintain the QoS requirements of the logical channels; and
transmitting the MAC-e PDU over an uplink transport channel with a transmitting element;
wherein the data from the plurality of logical channels is multiplexed based on relative priority of the logical channels, including a weight being defined for each logical channel and the multiplexing being performed according to the defined weights of the logical channels.

16. A wireless transmit/receive unit (WTRU) comprising:
a receiver to receive data over a plurality of logical channels, each logical channel being associated with a Quality of Service (QoS) requirement;
a multiplexor to multiplex data from the plurality of logical channels into an enhanced medium access control (MAC-e) protocol data unit (PDU) based on a priority associated with each of the plurality of the logical channels, wherein the multiplexing is to maintain the QoS requirements of the logical channels; and
a transmitter to transmit the MAC-e PDU over an uplink transport channel;
wherein the multiplexer is to multiplex the data from the plurality of logical channels based on relative priority of the logical channels, wherein a weight is defined for each logical channel and the multiplex
