Radio-network node, wireless device and methods performed therein
Embodiments herein relate to method performed by a radio-network node for handling a data transmission, from a wireless device to the radio-network node, in a wireless communication network. The radio-network node schedules one or more resources for carrying an uplink data transmission from the wireless device over a channel, and for carrying a feedback transmission, of a downlink data transmission from the radio-network node, over the same channel. The radio-network node transmits a control message to the wireless device, which control message indicates the one or more resources scheduled for carrying the uplink data transmission and the feedback transmission over the same channel.
1. A method performed by a base station in a wireless communication network for handling a data transmission from a user equipment, the method comprising:
scheduling one or more physical resources for carrying an uplink data transmission from the user equipment over a channel, and one or more physical resources for carrying a feedback transmission for a downlink data transmission from the base station, over the same channel; and
transmitting a single control message to the user equipment, wherein the control message indicates the one or more physical resources scheduled for carrying the uplink data transmission and wherein the control message further indicates the one or more physical resources scheduled for carrying the feedback transmission over the same channel; and
reading feedback information received over the channel according to the scheduled feedback transmission, wherein:
the feedback information is mapped to the one or more physical resources scheduled for carrying the feedback transmission;
uplink data is rate matched around the one or more physical resources scheduled for carrying the feedback transmission; and
the uplink data of the uplink data transmission is not punctured with the feedback information over the same channel.
2. The method according to claim 1 , further comprising:
determining based on the feedback information, whether or not to retransmit downlink data of the downlink data transmission.
3. The method according to claim 1 , wherein the control message comprises an uplink grant and the channel is a physical uplink shared channel.
4. A method performed by a user equipment for handling a data transmission to a base station in a wireless communication network, the method comprising:
receiving, from the base station, a single control message, wherein the control message indicates one or more physical resources scheduled for carrying an uplink data transmission over a channel and wherein the control message further indicates one or more physical resources scheduled for carrying a feedback transmission over the same channel, wherein the feedback transmission is for a downlink data transmission from the base station; and
performing the uplink data transmission and the feedback transmission to the base station over the same channel using the physical resources indicated in the control message;
wherein:
performing the uplink data transmission and the feedback transmission comprises mapping feedback information to the one or more physical resources scheduled for carrying the feedback transmission and rate matching uplink data around the one or more physical resources scheduled for carrying the feedback transmission; and
the uplink data of the uplink data transmission is not punctured with the feedback information of the uplink data transmission over the same channel.
5. The method according to claim 4 , further comprising:
receiving from the base station, the downlink data transmission; and
generating feedback information for the feedback transmission, based on reception of the downlink data transmission.
6. The method according to claim 4 , wherein the channel is a physical uplink shared channel and the control message comprises an uplink grant.
7. A base station, comprising:
transceiver circuitry configured for communication with a user equipment; and
processing circuitry operatively associated with the transceiver circuitry and configured to:
schedule one or more physical resources for carrying an uplink data transmission from the user equipment over a channel, and one or more physical resources for carrying a feedback transmission for a downlink data transmission from the base station, over the same channel;
transmit a single control message to the user equipment, wherein the control message indicates the one or more physical resources scheduled for carrying the uplink data transmission and wherein the control message further indicates one or more physical resources scheduled for carrying the feedback transmission over the same channel; and
read feedback information received over the channel according to the scheduled feedback transmission, wherein:
the feedback information is mapped to the one or more physical resources scheduled for carrying the feedback transmission;
uplink data is rate matched around the one or more physical resources scheduled for carrying the feedback transmission; and
the uplink data of the uplink data transmission is not punctured with the feedback information over the same channel.
8. The base station according to claim 7 , wherein the processing circuitry is configured to determine, based on the feedback information, whether or not to retransmit downlink data of the downlink data transmission.
9. The base station according to claim 7 , wherein the control message is an uplink grant and the channel is a physical uplink shared channel.
10. A user equipment, comprising:
transceiver circuitry configured for communication with a base station in a wireless communication network; and
processing circuitry operatively associated with the transceiver circuitry and configured to:
receive, from the base station, a single control message, wherein the control message indicates one or more physical resources scheduled for carrying an uplink data transmission over a channel and wherein the control message further indicates one or more physical resources scheduled for carrying a feedback transmission over the same channel, wherein the feedback transmission is for a downlink data transmission from the base station; and
perform the uplink data transmission and the feedback transmission to the base station over the same channel using the physical resources indicated in the control message;
wherein:
performing the uplink data transmission comprises mapping feedback information to the one or more physical resources scheduled for carrying the feedback transmission and rate matching uplink data around the one or more physical resources scheduled for carrying the feedback transmission; and
the uplink data of the uplink data transmission is not punctured with the feedback information over the same channel.
11. The user equipment according to claim 10 , further being configured to:
receive, from the base station, the downlink data transmission; and
generate feedback information for the feedback transmission, based on reception of the downlink data transmission.
12. The user equipment according to claim 10 , wherein the channel is a physical uplink shared channel and the control message comprises an uplink grant.
