Abstract

Embodiments herein relate to a method performed by a radio network node for handling transmission of data from a wireless device in a wireless communication network. The radio network node determines a delay value for a transmission of data from the wireless device based on a transmission type of data from the wireless device or a capability of the wireless device. The capability is related to a processing time for processing received data from the radio network node, or for processing data for transmission to the radio network node. The radio network node further transmits an indication, to the wireless device, which indication indicates the determined delay value.

First claim

What is claimed is:

1. A method performed by a user equipment for performing transmissions of data in a wireless communication network, the method comprising:
receiving, from a radio network node, an indication that indicates a delay value from a set of delay values for a transmission of data from the user equipment, wherein the delay value comprises a value of a delay that is to occur between when the user equipment receives a scheduling message and when the user equipment performs a transmission of data scheduled by that scheduling message;
before receiving the indication, receiving, from the radio network node, a control message that configures the user equipment with the set of one or more delay values;
comparing the indicated delay value with a minimum delay value with which the user equipment is capable of processing data; and
performing a transmission of data to the radio network node, with a timing based on the indicated delay value, if the indicated delay value is greater than or equal to the minimum delay value according to said comparing.

2. The method of claim 1 , wherein the set of delay values is a set of default delay values.

3. The method of claim 2 , wherein the set of default delay values is stored in a table at the user equipment.

4. The method of claim 1 , wherein the control message is a radio resource control (RRC) message.

5. The method of claim 1 , wherein the indication is comprised in downlink control information.

6. The method of claim 1 , wherein the indication is based on a capability of the user equipment, which capability is related to a processing time for processing received data from the radio network node, or for processing data for transmission to the radio network node.

7. The method of claim 6 , further comprising transmitting, to the radio network node, a capability indication indicating the capability related to the processing time of the user equipment.

8. A user equipment comprising processing circuitry and a memory, wherein the processing circuitry is configured to:
receive, from a radio network node, an indication that indicates a delay value from a set of delay values for a transmission of data from the user equipment, wherein the delay value comprises a value of a delay that is to occur between when the user equipment receives a scheduling message and when the user equipment performs a transmission of data scheduled by that scheduling message;
before receiving the indication, receive, from the radio network node, a control message that configures the user equipment with the set of one or more delay values;
perform a comparison of the indicated delay value with a minimum delay value with which the user equipment is capable of processing data; and
perform a transmission of data to the radio network node, with a timing based on the indicated delay value, if the indicated delay value is greater than or equal to the minimum delay value according to said comparison.

9. The user equipment of claim 8 , wherein the set of delay values is a set of default delay values.

10. The user equipment of claim 9 , wherein the set of default delay values is stored in a table at the user equipment.

11. The user equipment of claim 8 , wherein the control message is a radio resource control (RRC) message.

12. The user equipment of claim 8 , wherein the indication is comprised in downlink control information.

13. The user equipment of claim 8 , wherein the indication is based on a capability of the user equipment, which capability is related to a processing time for processing received data from the radio network node, or for processing data for transmission to the radio network node.

14. The user equipment of claim 13 , wherein the processing circuitry is further configured to transmit, to the radio network node, a capability indication indicating the capability related to the processing time of the user equipment.

15. A non-transitory computer-readable storage medium having stored thereon a computer program comprising instructions which, when executed on at least one processor of a user equipment, causes the user equipment to:
receive, from a radio network node, an indication that indicates a delay value from a set of delay values for a transmission of data from the user equipment, wherein the delay value comprises a value of a delay that is to occur between when the user equipment receives a scheduling message and when the user equipment performs a transmission of data scheduled by that scheduling message;
before receiving the indication, receive, from the radio network node, a control message that configures the user equipment with the set of one or more delay values;
perform a comparison of the indicated delay value with a minimum delay value with which the user equipment is capable of processing data; and
perform a transmission of data to the radio network node, with a timing based on the indicated delay value, if the indicated delay value is greater than or equal to the minimum delay value according to said comparison.
