Base station and user equipment
A base station for a mobile telecommunications system has circuitry which is configured to communicate with at least one user equipment. The circuitry is further configured to: transmit a short data transmission within the time scheduled for a long data transmission; and schedule, based on the transmission of the short data, a HARQ ACK/NACK response relating to at least a part of the long data transmission.
1. A base station for a mobile telecommunications system comprising circuitry configured to communicate with at least one user equipment, wherein the circuitry is further configured to:
schedule a long data transmission and a first Hybrid Automatic Repeat Request “HARQ” Acknowledgement/Negative Acknowledgement “ACK/NACK” response relating to the long data transmission;
transmit the long data transmission;
transmit a short data transmission, the short data transmission pre-empting a portion of the long data transmission;
send a post-indicator pertaining to whether the first HARQ ACK/NACK response is replaced by a second HARQ ACK/NACK response, maintained, or postponed;
schedule, based on the transmission of the short data, the second HARQ ACK/NACK response relating to at least a part of the long data transmission; and
retransmit the pre-empted portion of the long data transmission signal.
2. The base station of claim 1 , wherein the circuitry is further configured to retransmit at least a part of the long data transmission, based on the transmission of the short data.
3. The base station of claim 2 , wherein the scheduling of the second HARQ ACK/NACK response is performed when the first HARQ ACK/NACK response falls within a processing period of the user equipment for processing the received retransmitted pan of the long data transmission.
4. The base station of claim 1 , wherein the scheduling of the HARQ ACK/NACK response is signaled over a control channel.
5. The base station of claim 1 , wherein the post-indicator is a scheduling message.
6. The base station of claim 1 , wherein the scheduling of the HARQ ACK/NACK response includes scheduling of resources for transmission of the HARQ ACK/NACK response.
7. The base station of claim 1 , wherein the scheduling of the HARQ ACK/NACK response is transmitted based on a downlink control indicator.
8. The base station of claim 1 , wherein the long data transmission is an enhanced mobile broadband data transmission.
9. The base station of claim 1 , wherein the short data transmission is an ultra-reliable and low latency data transmission.
10. The base station of claim 1 , wherein the long data transmission is a physical downlink shared channel data transmission.
11. The base station of claim 1 , wherein the HARQ ACK/NACK response is transmitted over a physical uplink control channel.
12. A user equipment for a mobile telecommunications system comprising circuitry configured to communicate with at least one base station, wherein the circuitry is further configured to:
receive scheduling of a long data transmission and a first Hybrid Automatic Repeat Request “HARQ” Acknowledgement/Negative Acknowledgement “ACK/NACK” response relating to the long data transmission;
receive the long data transmission;
receive a short data transmission, the short data transmission pre-empting a portion of the long data transmission;
receive a post-indicator pertaining to whether the first HARQ ACK/NACK response is replaced by a second HARQ ACK/NACK response, maintained, or postponed;
receive a scheduling, based on the transmission of the short data, the second HARQ ACK/NACK response relating to at least a part of the long data transmission; and
receive a retransmission of the pre-empted portion of the long data transmission signal.
13. The user equipment of claim 12 , wherein the scheduling of the long transmission and the first and second HARQ ACK/NACK responses is received over a control channel.
14. The user equipment of claim 12 , wherein the second HARQ ACK/NACK response is transmitted after a predefined time period.
