Abstract

A Quality of Service (QOS) framework of mobile and wireless communication networks, particularly, the Fifth Generation (5G) QoS framework include a Radio Access Network (RAN) entity and User Equipment (UE) for enabling RAN awareness of a tolerance of an application to transmission failures of application data, and QoS treatment based on this resilience. The RAN entity is configured to receive information indicating at least one resilience parameter of the application, from a control entity, another RAN entity, and/or UE. The at least one resilience parameter is based on the tolerance of the application to transmission failures, in particular, consecutive transmission failures.

First claim

What is claimed is:

1. User equipment (UE), the UE comprising at least one processor, the UE being configured to, based on a transmission failure occurring in a semi-persistently scheduled (SPS) transmission of application data to or from the UE:
receive information indicating at least one resilience parameter of an application from a radio access network (RAN) entity, wherein the at least one resilience parameter is based on a tolerance of the application to consecutive transmission failures of application data; and
receive control information, wherein the control information comprises a dynamic resource allocation to override or extend a configured resource allocation for a subsequent SPS transmission of application data to or from the UE,
wherein the dynamic resource allocation provides a higher redundancy for the subsequent SPS transmission than the configured resource allocation.

2. The UE according to claim 1 , wherein: the dynamic resource allocation includes at least one of:
a downlink assignment,
an uplink grant, or
a sidelink grant.

3. The UE according to claim 1 , wherein the dynamic resource allocation provides the higher redundancy for the subsequent SPS transmission by at least one of:
increasing a number of resources for the subsequent SPS transmission,
increasing a number of retransmissions for the subsequent SPS transmission,
increasing a number of antennas to be used for the subsequent transmission,
adapting a modulation and coding scheme (MCS) for the subsequent SPS transmission, or
increasing a transmission power for the subsequent SPS transmission.

4. The UE according to claim 1 , further configured to:
set up a survival time counter for the application based on the information or the at least one resilience parameter.

5. The UE according to claim 4 , further configured to:
report channel state information (CSI) to the RAN entity based on a transmission failure of application data.

6. The UE according to claim 5 , configured to:
determine a content of the CSI and report the CSI based on the state of the survival time counter.

7. The UE according to claim 1 , wherein a robustness of a subsequent transmission is adapted based on the tolerance of the application to consecutive transmission failures.

8. A method for user equipment (UE) wherein the method comprises, based on a transmission failure occurring in a semi-persistently scheduled (SPS) transmission of application data to or from the UE:
receiving information indicating at least one resilience parameter of an application from a radio access network (RAN) entity, wherein the at least one resilience parameter is based on a tolerance of the application to consecutive transmission failures of application data; and
receiving control information, wherein the control information comprises a dynamic resource allocation to override or extend a configured resource allocation for a subsequent SPS transmission of application data to or from the UE,
wherein the dynamic resource allocation provides a higher redundancy for the subsequent SPS transmission than the configured resource allocation.

9. The method according to claim 8 , wherein:
the dynamic resource allocation includes at least one of:
a downlink assignment,
an uplink grant, or
a sidelink grant.

10. The method according to claim 8 , wherein the dynamic resource allocation provides the higher redundancy for the subsequent SPS transmission by at least one of:
increasing a number of resources for the subsequent SPS transmission,
increasing a number of retransmissions for the subsequent SPS transmission,
increasing a number of antennas to be used for the subsequent transmission,
adapting a modulation and coding scheme (MCS) for the subsequent SPS transmission, or
increasing a transmission power for the subsequent SPS transmission.

11. The method according to claim 8 , further comprising:
setting up a survival time counter for the application based on the information or the at least one resilience parameter.

12. The method according to claim 11 , further comprising:
reporting channel state information (CSI) to the RAN entity based on a transmission failure of application data.

13. The method according to claim 12 , further comprising:
determining a content of the CSI and reporting the CSI based on the state of the survival time counter.

14. A user equipment (UE) comprising at least one processor, wherein the UE is configured to, based on a transmission failure occurring in a semi-persistently scheduled (SPS) transmission of application data to or from the UE:
receive information indicating at least one resilience parameter of an application from a radio access network (RAN) entity, wherein the at least one resilience parameter is based on a tolerance of the application to consecutive transmission failures of application data:
set up a survival time counter for the application based on the information or the at least one resilience parameter:
determine a content of a channel state information (CSI) and report the CSI to the RAN entity based on the state of the survival time counter; and
receive control information, wherein the control information comprises a dynamic resource allocation to override or extend a configured resource allocation for a subsequent SPS transmission of application data to or from the UE, wherein the dynamic resource allocation provides a higher redundancy for the subsequent SPS transmission than the configured resource allocation.
