Method and apparatus for data transmission with user selection
First Claim
1. A method comprising:
- selecting a transmit group to which to transmit during a first coherence time interval, wherein the transmit group is selected from a plurality of users for which there is data to transmit during the first coherence time interval;
transmitting the data associated with users in the transmit group to the transmit group during the first coherence time interval;
selecting subsequent transmit groups to which to transmit during subsequent coherence time intervals, wherein a user of the plurality of users is selected for transmission over the course of the first coherence time interval and the subsequent coherence time intervals with a predetermined probability, wherein the predetermined probability is a probability of the user being randomly selected for data transmission, and wherein the predetermined probability is independent of and not influenced by a probability of successful data reception by the user; and
using an error correcting code to protect data to be transmitted to the user of the plurality of users, wherein the error correcting code is configured to enable the user to recover the data from the transmission over the course of the first coherence time interval and the subsequent coherence time intervals in which the user is selected to be in the transmit groups with the predetermined probability.

Abstract
Various methods and devices are provided to address the need for improved data transmission with coherence interval user selection. In one method, a transmit group to which to transmit during a first coherence time interval is selected. The transmit group is selected (101) from a plurality of users for which there is data to transmit during the first coherence time interval. The data associated with users in the transmit group is transmitted (102) to the transmit group during the first coherence time interval. Subsequent transmit groups to which to transmit during subsequent coherence time intervals are also selected (103). A user of the plurality of users is selected for transmission over the course of the first coherence time interval and the subsequent coherence time intervals with a predetermined probability.
