Abstract
The present patent application improves DARP by allowing multiple users on one time slot (MUROS). It comprises means and instructions for sharing signals on a single channel, comprising setting up a new connection, allocating a new time slot if there is an unused time slot on a channel frequency, selecting an used time slot for the new connection to share with an existing connection if there is not an unused time slot on the channel frequency, and selecting a different training sequence code for the new connection if the used time slot on the channel frequency has been selected for the new connection to share with an existing connection.
Claims24
A method to identify if a remote station is MUROS capable, comprising:
- establishing an interference rejection ability of the remote station in a given environment by sending a discovery burst that includes a speech signal with a known interference pattern;
- allocating the remote station to an available shared slot;
- and
- permitting a pairing with another remote station.
An apparatus for identifying if a remote station is MUROS capable, comprising:
- means for establishing an interference rejection ability of the remote station in a given environment by sending a discovery burst that includes a speech signal with a known interference pattern;
- means for allocating the remote station to an available shared slot;
- and
- means for permitting a pairing with another remote station.
A base station, comprising:
- a controller processor;
- an antenna;
- a duplexer switch operably connected to said base station antenna;
- a receiver front end operably connected to said duplexer switch;
- a receiver demodulator operably connected to said receiver front end;
- a channel decoder and de-interleaver operably connected to said receiver demodulator and said controller processor;
- a base station controller interface operably connected to said controller processor;
- a coder and interleaver operably connected to said controller processor;
- a transmitter modulator operably connected to said coder and interleaver;
- a transmitter front end module operably connected to said transmitter modulator and operably connected to said duplexer switch;
- a data bus operably connected between said controller processor and said channel decoder and de-interleaver, said receiver demodulator, said receiver front end, said transmitter modulator and said transmitter front end;
- and
- software stored in said memory, wherein said software comprises instructions that, when executed by the controller processor, cause the controller processor to identify if a remote station is MUROS capable, the instructions comprising instructions to:
- establish an interference rejection ability of the remote station in a given environment;
- allocate the remote station to an available shared slot;
- and
- permit a pairing with another remote station.
