Abstract

Systems and methods of providing RAT co-existence and congestion control in V2V communications are generally described. A vUE detects specific non-LTE RAT transmissions in a listening period of a PSCCH or PSSCH, determines whether a metric has been met and reselects to a non-overloaded channel to communicate with other vUEs or the eNB. The manner of reselection is dependent on the RAT specific or V2X service priorities of the channels, as well as whether the channels are V2V service dependent.

Claims30

Dependent claims

An apparatus of a vehicle user equipment (vUE), the apparatus comprising:

an interface to send communications to and receive communications from at least one of an evolved NodeB (eNB) or another vUE;
and
processing circuitry in communication with the interface and arranged to:
determine, in a channel of a sidelink subframe used in communication between vUEs, that a predetermined listening interval has been reached, the channel allocated to a long term evolution (LTE) vehicle-to-vehicle (V2V) radio access technology (RAT), the predetermined listening interval configured to be devoid of LTE radio frequency (RF) signals;
detect at least one of a V2V or non-V2V signal in the channel during the predetermined listening interval;
determine that a non-LTE RAT is in operation in the channel based on detection of the at least one of the V2V or non-V2V signal in the channel during the predetermined listening interval;
and
determine whether to one of drop packet transmission or select another channel for transmission, of multiple channels allocated to the LTE-V2V RAT and the non-LTE RAT, in response to a determination that the non-LTE RAT is in operation in the channel, the selection based on allocation priorities of the multiple channels for the LTE-V2V RAT and the non-LTE RAT and conducted measurements in a given channel.

5 more elements

An apparatus of an evolved NodeB (eNB), the apparatus comprising:

an interface to an interface to send communications to and receive communications from a vehicle user equipment (vUE);
and
processing circuitry in communication with the interface and arranged to:
encode, for transmission to the vUE, an indication of a predetermined listening interval, the listening interval disposed in at least one of a physical sidelink control channel (PSCCH) or physical sidelink shared channel (PSSCH) and devoid of long term evolution (LTE) radio frequency (RF) signals between the vUE and the eNB;
allocate multiple channels to a LTE vehicle-to-vehicle (V2V) radio access technology (RAT), the multiple channels simultaneously allocated to a non-LTE RAT;
and
encode, for transmission to the vUE, an indication at least one metric for measurement of sidelink V2V transmissions for one of dropping by the vUE of packet transmission or selection by the vUE from one of the multiple channels to another of the multiple channels in response to the metric being reached.

4 more elements

A computer-readable storage medium that stores instructions for execution by one or more processors of a vehicle user equipment (vUE), the one or more processors to configure the vUE to:

detect, in a channel allocated to a long term evolution (LTE) vehicle-to-vehicle (V2V) radio access technology (RAT) and to a non-LTE RAT, non-LTE RF signals in a punctured region of a last symbol of a physical sidelink control channel (PSCCH) or physical sidelink shared channel (PSSCH) that is configured by the eNB to be devoid of LTE radio frequency (RF) signals;
and
select to a non-overloaded channel to communicate with at least one of another vUE or the eNB dependent on at least one metric for sidelink V2V transmissions.
