Abstract
Facilitating configurable hybrid automatic repeat request (HARQ) feedback types for new radio sidelink communication can be performed for a 5G wireless network. Based on whether reception of data was successful or not, a reception node can send acknowledgement (ACK) data or negative acknowledgement (NACK) data to a base station using an uplink control signal. Therefore, the feedback data can be used to manage subsequent resource allocation decisions within the 5G wireless network.
Claims20
A method, comprising:
- receiving, by first network equipment comprising a processor from second network equipment, resource data representative of a configured resource for a physical sidelink feedback channel to be used by third network equipment;
- receiving, by the first network equipment, an indication that the physical sidelink feedback channel is associated with a physical sidelink control channel;
- in response to receiving the indication, transmitting, by the first network equipment, index data representative of the configured resource to be utilized by the third network equipment to transmit acknowledgement data via the physical sidelink feedback channel, wherein the acknowledgement data is representative of an acknowledgement that the third network equipment has received the configured resource, via the physical sidelink feedback channel;
- receiving, by the first network equipment, scheduling request data, representative of a scheduling request, by the first network equipment from the second network equipment, wherein the scheduling request data comprises V2X unicast traffic data;
- in response to receiving the scheduling request data, transmitting, by the first network equipment to the second network equipment, downlink control information, wherein the downlink control information comprises scheduling data;
- and
- in response to receiving the scheduling request data, facilitating establishing, by the first network equipment, a physical sidelink scheduling channel between the third network equipment and the second network equipment for the second network equipment to receive radio data.

First network equipment, comprising:
- a processor;
- and
- a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
- receiving, from second network equipment, resource data representative of a configured resource for a physical sidelink feedback channel to be used by third network equipment;
- receiving an indication that the physical sidelink feedback channel is associated with a physical sidelink control channel;
- in response to receiving the indication, transmitting index data representative of the configured resource to be utilized by the third network equipment to transmit acknowledgement data via the physical sidelink feedback channel, wherein the acknowledgement data is representative of an acknowledgement that the third network equipment has received the configured resource;
- receiving scheduling request data representative of a scheduling request, from the second network equipment, wherein the scheduling request data comprises V2X unicast traffic data;
- in response to receiving the scheduling request data, transmitting downlink control data to the second network equipment, wherein the downlink control data comprises scheduling data;
- and
- in response to receiving the scheduling request data, establishing a physical sidelink scheduling channel between the third network equipment and the second network equipment.

A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processor of a first network device, facilitate performance of operations, comprising:
- receiving, from first network equipment, resource data representative of a configured resource for a physical sidelink feedback channel to be used by second network equipment;
- receiving an indication that the physical sidelink feedback channel is associated with a physical sidelink control channel;
- facilitating transmitting index data representative of the configured resource to be utilized by the second network equipment to transmit acknowledgement data via the physical sidelink feedback channel, wherein the acknowledgement data is representative of an acknowledgement that the second network equipment has received the configured resource;
- receiving scheduling request data, representative of a scheduling request, from the first network equipment, wherein the scheduling request data comprises V2X unicast traffic data;
- in response to receiving the scheduling request data, facilitating transmitting, to the first network equipment, downlink control information, wherein the downlink control information comprises scheduling data;
- and
- in response to receiving the scheduling request data, facilitating establishing a physical sidelink scheduling channel between the second network equipment and the first network equipment for the first network equipment to receive radio data.
