US 2022/0046715 A1 · METHOD AND APPARATUS FOR PROVIDING NON-SCHEDULED NETWORK ACCESS

Abstract

A terminal device selects are source indicator to be used for non-scheduled access and transmits it to an access device of the network in the non-scheduled access. If it determines based on a response to the non-scheduled access, that it has selected the same resource indicator as another terminal device, it keeps the resource indicator but selects different physical random access channel occasions by setting a time offset for a retransmission with the selected resource indicator. An initial waiting time may be determined by the access device (e.g. based on a traffic amount on the access channel) and transmitted to the terminal device for setting the time offset. Also, a layer (2) error caused by a random access channel resource collision of terminal devices may be determined at the access device and a feedback indicating a non-acknowledgement for layer (2) may be transmitted to colliding terminal devices.

Dependent claims

An apparatus, comprising:

at least one processor;
and
at least one memory including computer program code, the at least one memory and computer program code configured to, with the at least one processor, cause the apparatus to perform:
selecting a resource indicator which indicates a channel resource to be used by a terminal device for non-scheduled access to a network;
transmitting the selected resource indicator to an access device of the network;
and
maintaining the selected resource indicator and setting a time offset for a retransmission with the selected resource indicator based on a response received from the access device responsive to the non-scheduled access.
