Radio bearers for machine type communication
First Claim
1. A wireless communication method for machine type communication, MTC, the method comprising:
- defining by a base station a cell for wireless communication of the base station with devices within the cell via a downlink from the base station and via an uplink to the base station using one or more radio bearers; and
performing wireless communication of the base station with a plurality of MTC devices by;
sharing a radio bearer by the plurality of MTC devices on the downlink by taking turns to receive data from the base station according to a predetermined schedule and on the uplink by taking turns to transmit data to the base station according to a predetermined schedule;
the base station recording each MTC device as a member of a group and assigning to each MTC device a first respective timing within a predetermined time period for the MTC device to transmit data on the uplink based on information which distinguishes the MTC device within the group, and a second respective timing for the MTC device to receive data from the base station, the second respective timing derived from said first respective timing.

Abstract
A wireless communication method for machine type communication (MTC) where a base station defines a cell for wireless communication of the base station with devices within the cell via a downlink from the base station and via an uplink to the base station using one or more radio bearers; and a plurality of MTC devices are in wireless communication with the base station. The plurality of MTC devices share a radio bearer on at least one of the downlink by taking turns to receive data from the base station according to a predetermined schedule; or the uplink by taking turns to transmit data to the base station according to a predetermined schedule and the base station records each MTC device as a member of a group and assigns to each MTC device a first respective timing based on information which distinguishes the MTC device within the group.
