Problems solved by technology

Furthermore, some types of communication are delay sensitive and may require at least some data rate and / or some quality of service without retransmitting lost data
Certain system bandwidth may result in less than acceptable quality of service or inefficient use of bandwidth for these types of communications

Embodiment Construction

[0056] Methods, systems, and devices for supporting voice in wireless communication systems are described. Some embodiments use multiple code channels to transmit voice frames. These embodiments may include: conventional frame boundary embodiments, offset multi-code embodiments, parallel multi-code embodiments, and / or multi-user multi-code embodiments. These multiple code embodiments can use flexible or normal bandwidth systems. For example, a flexible bandwidth communication system may use a code channel in which a scaling factor that expands the symbol rate of the code channel is applied to the chip rate or symbol rate. In some embodiments, the number of code channels may be greater than the scaling factor for flexible bandwidth code channels.

[0057] Some embodiments transmit a subset of subframes of voice frames on one or more flexible bandwidth code channels. The number of subframes transmitted may be based on a scaling factor of one or more flexible bandwidth code ch...

Abstract

Methods, systems, and devices for supporting voice communications in a wireless communications system are provided. Some embodiments utilize multiple code channels to transmit the voice frames. These embodiments include parallel multi-code embodiments, offset multi-code embodiments, and multi-user multi-code embodiments. Some embodiments utilize flexible carrier bandwidths systems that may utilize portions of spectrum that may not be big enough to fit a normal bandwidth waveform. Some embodiments transmit and receive a subset of subframes of voice frames received over flexible bandwidth code channels. In some embodiments, a subset of subframes based on a flexible bandwidth scaling factor of one or more flexible bandwidth code channels is transmitted. The receiver may decode the voice frame based on the received subset of subframes. An outer loop power control set-point may be adjusted to provide a predetermined frame error rate based on the number of transmitted subframes.
