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 PSSCH 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.
Claims20
A method for a base station to allocate at least one sub-channel for device-to-device (D2D) communication, comprising:
- transmitting, to a user equipment device (UE), an indication of the at least one sub-channel and resource pools the UE uses for communication with other UEs and not for transmissions to the base station, wherein the resource pools are disposed in a physical sidelink channel;
- and
- transmitting, to the UE, an indication of at least one metric for measurement of D2D transmissions for adjustment of transmission parameters on the at least one allocated sub-channel and the resource pools.
A base station, comprising:
- an interface configured for wireless communication;
- and
- a processor in communication with the interface and configured to cause the base station to:
- transmit, to a user equipment device (UE), an indication of at least one sub-channel and resource pools the UE uses for communication with other UEs and not for transmissions to the base station, wherein the resource pools are disposed in a physical sidelink channel;
- and
- transmit, to the UE, an indication of at least one metric for measurement of D2D transmissions for adjustment of transmission parameters on the at least one sub-channel and the resource pools.
An apparatus, comprising:
- a memory;
- and
- a processor in communication with the memory and configured to:
- transmit, to a user equipment device (UE), an indication of at least one sub-channel and resource pools the UE uses for communication with other UEs and not for transmissions to a base station associated with the apparatus, wherein the resource pools are disposed in a physical sidelink channel;
- and
- transmit, to the UE, an indication of at least one metric for measurement of D2D transmissions for adjustment of transmission parameters on the at least one sub-channel and the resource pools.
