User diversity for muros callers

摘要

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.

1. A method to establish user diversity for MUROS callers, comprising:
frequency hopping the MUROS callers among a plurality of frequencies, pairing a group of the MUROS callers with each other on a same frequency of the plurality of frequencies in a random fashion to reduce a probability that the paired MUROS callers in the group are transmitting voice calls while both are in a discontinuous transmission mode; and selecting MUROS callers for the group based on a distance between each of the MUROS callers and a base station.
