Method and system for network slice-specific propagation delay compensation
A method, a network device, and a non-transitory computer-readable storage medium are described in relation to an propagation delay compensation service. The propagation delay compensation service may calculate or select propagation delay compensation method and configuration data based on a time synchronization error budget value, which may be calculated based on quality of service information associated with a network slice, network slice information, and time sensitive communication assistance information. The propagation delay compensation service may calculate or select the propagation delay compensation method and configuration data based on other context information.

selecting, by the one or more RAN devices, a propagation delay compensation method and a configuration based on the network slice information, the TSNAI, a User Equipment (UE) Power Class value of an end device, and access barring information pertaining to the end device; and
transmitting, by the one or more RAN devices, a message that includes data indicating the propagation delay compensation method and the configuration, to the end device.
2 . The method of claim 1 , wherein the QoS information is correlated to a Fifth Generation QoS identifier ( 5 Q 1 ) pertaining to the network slice.

5 . The method of claim 1 , wherein the QoS information includes single network slice selection assistance information (S-NSSAI).
6 . The method of claim 1 , further comprising:
determining, by the one or more RAN devices, that the network slice is a TSN slice.
7 . The method of claim 1 , wherein the time synchronization error budget includes an error budget for the one or more RAN devices to provide access stratum time to the end device.
8 . The method of claim 1 , wherein the RAN devices are a next generation Node B.
9 . One or more network devices comprising:
one or more processors that are configured to:
receive network slice information pertaining to a network slice, wherein the one or more network devices are a radio access network (RAN) device;
receive time sensitive network assistance information (TSNAI) that includes a time synchronization error budget calculated based on quality of service (QOS) information associated with the network slice;
select a propagation delay compensation method and a configuration based on the network slice information, the TSNAI, a User Equipment (UE) Power Class value of an end device, and access barring information pertaining to the end device; and
transmit a message that includes data indicating the propagation delay compensation method and the configuration, to an end device.
10 . The one or more network devices of claim 9 , wherein the QoS information is correlated to a Fifth Generation QoS identifier ( 5 Q 1 ) pertaining to the network slice.
11 . The one or more network devices of claim 10 , wherein the one or more processors are further configured to:
select the propagation delay compensation method and the configuration based on congestion information at the one or more network devices.
12 . The one or more network devices of claim 9 , wherein the TSNAI includes a survival time value.
13 . The one or more network devices of claim 9 , wherein the QoS information includes single network slice selection assistance information (S-NSSAI).
14 . The one or more network devices of claim 9 , wherein the one or more processors are further configured to:
determine that the network slice is a TSN slice.
15 . The one or more network devices of claim 9 , wherein the time synchronization error budget includes an error budget for the one or more network devices to provide access stratum time to the end device.
16 . The one or more network devices of claim 9 , wherein the RAN device is a next generation Node B.
17 . A non-transitory computer-readable storage medium storing instructions executable by one or more processors of one or more network devices of a radio access network, wherein the instructions are configured to:
receive network slice information pertaining to a network slice;
receive time sensitive network assistance information (TSNAI) that includes a time synchronization error budget calculated based on quality of service (QOS) information associated with the network slice;
select a propagation delay compensation method and a configuration based on the network slice information, the TSNAI, a User Equipment (UE) Power Class value of an end device, and access barring information pertaining to the end device; and
transmit a message that includes data indicating the propagation delay compensation method and the configuration, to the end device.
18 . The non-transitory computer-readable storage medium of claim 17 , wherein the QoS information is correlated to a Fifth Generation QoS identifier ( 5 Q 1 ) pertaining to the network slice.
