Abstract

Methods and apparatuses for uplink and downlink wireless communication are presented. For example, a method of uplink mobile communication at a user equipment is presented, which may include compressing two consecutive voice packets having a first voice packet transmission time interval into two compressed voice packets having a second voice packet TTI. In addition, the method may include compressing signaling data corresponding to a first dedicated control channel (DCCH) TTI into compressed signaling data having a second DCCH TTI and multiplexing the two compressed voice packets and the compressed signaling data to form a multiplexed packet. Furthermore, the method may include splitting the multiplexed packet into a first and second subpacket, transmitting the first subpacket during a first subpacket interval having a subpacket TTI, and transmitting the second subpacket during a second subpacket interval subsequent to the first subpacket interval, wherein the second subpacket interval has the subpacket TTI.

multiplexing the two compressed voice packets and the compressed signaling data to form a multiplexed packet;
splitting the multiplexed packet into a first subpacket and a second subpacket;
transmitting the first subpacket during a first subpacket interval having a subpacket TTI; and
transmitting the second subpacket during a second subpacket interval subsequent to the first subpacket interval, wherein the second subpacket interval has the subpacket TTI.

2. The method of claim 1 , further comprising pausing transmission for a time interval following the transmission of each of the first subpacket and the second subpacket.

3. The method of claim 2 , wherein the time interval comprises a discontinuous transmission (DTX) interval.

4. The method of claim 1 , wherein the second DCCH TTI corresponds to half of the first DCCH TTI.

5. The method of claim 1 , wherein each of the two compressed voice packets have a second voice packet TTI corresponding to half of the first voice packet TTI.

6. The method of claim 1 , wherein the second DCCH TTI corresponds to twice the second voice packet TTI.

7. The method of claim 1 , wherein the first voice packet TTI is 20 ms in duration.

8. The method of claim 1 , wherein each of the first subpacket and the second subpacket have a subpacket TTI corresponding to the second voice packet TTI.

9. An apparatus, comprising:
a voice packet compression component configured to compress two consecutive voice packets having a first voice packet transmission time interval (TTI) into two compressed voice packets having a second voice packet TTI;
a signaling data compression component configured to compress signaling data corresponding to a first dedicated control channel (DCCH) TTI into compressed signaling data having a second DCCH TTI;
a multiplexing component configured to multiplex the two compressed voice packets and the compressed signaling data to form a multiplexed packet;
