Slotted Access For Wireless Communication Devices And Control Thereof

摘要

An example method provides a method of determining access times and channels for a wireless communication device. One embodiment includes selecting, at a wireless communication device, one of a plurality of time intervals in a periodically repeating access cycle for transmission of an access signal based on an identification number identifying the wireless communication device, negotiating a preamble assignment for the selected one of the plurality of time intervals, and transmitting the access signal over an access channel in the selected one of the plurality of time intervals using a preamble corresponding to the preamble assignment.

主权项

1. A method comprising:
receiving, at a machine-type communication (MTC) device from a network node, at a power-up initialization stage of the MTC device, a pre-assigned access slot and preamble for transmission of an access signal; and for one or more future access attempts, transmitting, at the MTC device, the access signal over an access channel in the pre-assigned access slot using the pre-assigned preamble.
