Abstract

The present patent application improves DARP by allowing multiple users on one time slot (MUROS). It comprises means and instructions for signaling training sequence set information to a remote station, comprising receiving signaling from a remote station indicating if a new set of training sequences is supported, and using a channel description to signal the training sequence set to be used by the remote station for a communication channel being established. Other aspects, embodiments, and features are also claimed and described.

Claims

1. A method for wireless communication by a remote station, comprising:

obtaining multiple training sequence codes, wherein the multiple training sequence codes are signaled by a base station in a channel description information element identifier that indicates whether to use a new set of training sequences or a legacy set of training sequences, and wherein each training sequence of the new set is different than the training sequences of the legacy set;

combining paired timeslots into one timeslot;

decoding a first burst and a second burst using a first training sequence code; and

decoding a third burst and a fourth burst using a second training sequence code.

2. The method of claim 1, wherein the channel description information element identifier has a channel type and a time division multiple access offset field.

3. An apparatus for wireless communication, comprising:

a processor;

memory in electronic communication with the processor; and

instructions stored in the memory, the instructions being executable by the processor to;

obtain multiple training sequence codes, wherein the multiple training sequence codes are signaled by a base station in a channel description information element identifier that indicates whether to use a new set of training sequences or a legacy set of training sequences, and wherein each training sequence of the new set is different than the training sequences of the legacy set;

combine paired timeslots into one timeslot;

decode a first burst and a second burst using a first training sequence code; and

decode a third burst and a fourth burst using a second training sequence code.

4. The apparatus of claim 3, wherein the channel description information element identifier has a channel type and a time division multiple access offset field.

5. An apparatus for wireless communication, comprising:

means for obtaining multiple training sequence codes, wherein the multiple training sequence codes are signaled by a base station in a channel description information element identifier that indicates whether to use a new set of training sequences or a legacy set of training sequences, and wherein each training sequence of the new set is different than the training sequences of the legacy set;

means for combining paired timeslots into one timeslot;

means for decoding a first burst and a second burst using a first training sequence code; and

means for decoding a third burst and a fourth burst using a second training sequence code.

6. The apparatus of claim 5, wherein the channel description information element identifier has a channel type and a time division multiple access offset field.

7. A computer-program product for wireless communications, the computer-program product comprising a non-transitory computer-readable medium having instructions thereon, the instructions comprising:

code for causing a remote terminal to obtain multiple training sequence codes, wherein the multiple training sequence codes are signaled by a base station in a channel description information element identifier that indicates whether to use a new set of training sequences or a legacy set of training sequences, and wherein each training sequence of the new set is different than the training sequences of the legacy set;

code for causing the remote terminal to combine paired timeslots into one timeslot;

code for causing the remote terminal to decode a first burst and a second burst using a first training sequence code; and

code for causing the remote terminal to decode a third burst and a fourth burst using a second training sequence code.

8. The computer-program product of claim 7, wherein the channel description information element identifier has a channel type and a time division multiple access offset field.
