Abstract
A cellular communications system in which transmission of control signals for plural different remote stations is so displaced in time that the transmission of control signals for one remote station does not interfere with the transmission of control signals for another remote station, the displacement being sufficient to prevent contemporaneous reception of control signals by the remote station intended for the other remote station. Other aspects, embodiments, and features are also claimed and described.
Claims40
A method for determining capabilities of a remote terminal by a base station, the method comprising:
- maintaining an active voice call with the remote terminal;
- sending a single discovery burst to the remote terminal;
- receiving a response from the remote terminal;
- and
- determining whether the remote terminal is capable of multi-user on one slot operation based on the response.
An apparatus for determining capabilities of a remote terminal by a base station, comprising:
- a processor;
- memory in electronic communication with the processor;
- and
- instructions stored in the memory, the instructions being executable by the processor to:
- maintain an active voice call with the remote terminal;
- send a single discovery burst to the remote terminal;
- receive a response from the remote terminal;
- and
- determine whether the remote terminal is capable of multi-user on one slot operation based on the response.
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 base station to maintain an active voice call with a remote terminal;
- code for causing the base station to send a single discovery burst to the remote terminal;
- code for causing the base station to receive a response from the remote terminal;
- and
- code for causing the base station to determine whether the remote terminal is capable of multi-user on one slot operation based on the response.
A method for providing capabilities of a remote terminal to a base station, the method comprising:
- maintaining an active voice call with the base station;
- receiving a single discovery burst from the base station;
- and
- sending a response to the base station, wherein the response indicates whether the remote terminal is capable of multi-user on one slot operation.
An apparatus for providing capabilities of a remote terminal to a base station, comprising:
- a processor;
- memory in electronic communication with the processor;
- and
- instructions stored in the memory, the instructions being executable by the processor to:
- maintain an active voice call with the base station;
- receive a single discovery burst from the base station;
- and
- send a response to the base station, wherein the response indicates whether the remote terminal is capable of multi-user on one slot operation.
An apparatus for determining capabilities of a remote terminal by a base station, comprising:
- means for maintaining an active voice call with the base station;
- means for receiving a single discovery burst from the base station;
- and
- means for sending a response to the base station, wherein the response indicates whether the remote terminal is capable of multi-user on one slot operation.
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 maintain an active voice call with a base station;
- code for causing the remote terminal to receive a single discovery burst from the base station;
- and
- code for causing the remote terminal to send a response to the base station, wherein the response indicates whether the remote terminal is capable of multi-user on one slot operation.
