Generating and processing MAC-ehs protocol data units
A Node-B may prioritize a service data unit (SDU) associated with a logical channel of a priority queue that is associated with a segmentation component. A Node-B may also prioritize other SDUs associated with another priority queue associated with another segmentation component. The segmentation component may facilitate generating an enhanced high speed medium access control (MAC-ehs) reordering protocol data unit (PDU) that includes a segment of the SDU to transmit a MAC-ehs PDU on a high speed downlink shared channel (HS-DSCH).
1. A network device comprising:
a processor; and
a transmitter;
wherein the processor is configured:
to prioritize, based on enhanced high speed medium access control (MAC-ehs) protocol rules, a MAC-ehs service data unit (SDU) associated with a logical channel of a first priority queue associated with a first segmentation function and MAC-ehs SDUs from other logical channels associated with the first priority queue;
to segment, by the first segmentation function based on the MAC-ehs protocol rules, the MAC-ehs SDU for a MAC-ehs reordering protocol data unit (PDU);
to prioritize, based on the MAC-ehs protocol rules, other MAC-ehs SDUs associated with a second priority queue that is associated with a second segmentation function; and
to generate, based on the MAC-ehs protocol rules, a MAC-ehs PDU that includes the MAC-ehs reordering PDU; and
the transmitter is configured to transmit the MAC-ehs PDU on a high speed downlink shared channel (HS-DSCH).
2. The network device of claim 1 , wherein the generation of the MAC-ehs PDU is performed by a priority queue multiplexing entity.
3. The network device of claim 1 , wherein the MAC-ehs PDU comprises a plurality of MAC-ehs reordering PDUs.
4. The network device of claim 1 , wherein the MAC-ehs reordering PDU comprises a complete MAC-ehs SDU and the segment of the MAC-ehs SDU.
5. The network device of claim 1 , wherein the first segmentation function segments based on any one of a current channel condition, a selected transport format and resource combination (TFRC), or a size of the MAC-ehs reordering PDU.
6. The network device of claim 1 , wherein the first segmentation function facilitates generation of a first MAC-ehs reordering PDU and a second MAC-ehs reordering PDU to include in the MAC-ehs PDU.
7. The network device of claim 1 , wherein the MAC-ehs PDU comprises a plurality of MAC-ehs reordering PDUs that are each associated with a different priority queue.
8. A method performed by a network device, the method comprising:
prioritizing, based on enhanced high speed medium access control (MAC-ehs) protocol rules, a MAC-ehs service data unit (SDU) associated with a logical channel of a first priority queue associated with a first segmentation function and MAC-ehs SDUs from other logical channels associated with the first priority queue;
segmenting, by the first segmentation function based on the MAC-ehs protocol rules, the MAC-ehs SDU for a MAC-ehs reordering protocol data unit (PDU);
prioritizing, based on the MAC-ehs protocol rules, other MAC-ehs SDUs associated with a second priority queue that is associated with a second segmentation function;
generating, based on the MAC-ehs protocol rules, a MAC-ehs PDU that includes the MAC-ehs reordering PDU; and
transmitting the MAC-ehs PDU on a high speed downlink shared channel (HS-DSCH).
9. The method of claim 8 , wherein the generating of the MAC-ehs PDU is performed by a priority queue multiplexing entity.
10. The method of claim 8 , wherein the MAC-ehs PDU comprises a plurality of MAC-ehs reordering PDUs.
11. The method of claim 8 , wherein the MAC-ehs reordering PDU comprises a complete MAC-ehs SDU and the segment of the MAC-ehs SDU.
12. The method of claim 8 , wherein the first segmentation function segments based on any one of a current channel condition, a selected transport format and resource combination (TFRC), or a size of the MAC-ehs reordering PDU.
13. The method of claim 8 further comprising the first segmentation function facilitates generating a first MAC-ehs reordering PDU and a second MAC-ehs reordering PDU to include in the MAC-ehs PDU.
