Abstract

The present invention relates to the fields of mobile communication, connected driving, Internet of vehicles (IoV), self-driving car, and autonomous car. More specifically, the present invention relates to side-link communication and network slicing. The present invention provides a control unit 100 for assisting side-link communication for at least one slice 101 of a communication network, wherein the control unit 100 is configured to obtain at least one of an upper layer requirement 102, and a session requirement 103; and to configure, for the at least one slice 101, at least one side-link resource pool 104 based on the upper layer requirement 102 and/or session requirement 103.

First claim

What is claimed is:

1 . A control unit ( 100 ) for assisting side-link communication for at least one slice ( 101 ) of a communication network, wherein the control unit ( 100 ) is configured to:
obtain at least one of an upper layer requirement ( 102 ), and a session requirement ( 103 ), configure, for the at least one slice ( 101 ), at least one side-link resource pool ( 104 ) based on the upper layer requirement ( 102 ) or session requirement ( 103 ).

2 . The control unit ( 100 ) according to claim 1 , further configured to obtain the upper layer requirement ( 102 ) from a management entity or application entity.

3 . The control unit ( 100 ) according to claim 1 , wherein the upper layer requirement ( 102 ) includes at least one of the following configuration parameters:
Slice identifier or Network Slice Network Slice Selection Assistance Information, NSSAI, and/or Slice Profile identifier; Slice policies per side-link service for a network domain, in particular Radio Resource Management, RRM, policies for Radio Access Network, RAN, domain; slice mapping information for mapping at least one of a session and a service to at least one slice; mode mapping information for mapping a service to a first or a second operation mode; Geographical Area; Time Validity; Application or Network Management statistics/analytics on network and/or application related conditions.

4 . The control unit ( 100 ) according to claim 1 , wherein the session requirement ( 103 ) includes at least one of the following parameters:
Slice identifier and/or S-NSSAI/NSSAI; Session identifier; Group terminal device information identifier; Session Resource Setup Request Transfer for side-link session; Side-link Aggregate Maximum Bit Rate, AMBR; Side-link Quality of Service, QoS, levels; mode mapping information for mapping a service to a first or a second operation mode; a list of available slices for the terminal device; a list of resource pools available to the terminal device for each slice.

5 . The control unit ( 100 ) according to claim 1 , wherein the session requirement ( 103 ) includes at least one of a network requirement obtained by a network entity and a terminal device requirement obtained from a terminal device for side-link communication.

6 . The control unit ( 100 ) according to claim 1 , wherein the at least one side-link resource pool configuration ( 104 ) comprises at least one of the following parameters:
Slice identifier or NSSAI or S-NSSAI; Group terminal device information identifier; Allocated resources per side-link session; Common Rx Pool List; Common Tx Pool List; side-link Resource Pool Configuration information; Slice Radio Resource Management, RRM, Policies; Resource Selection information; Geographical Area; Time Validity; mode mapping information for mapping a service to a first or a second operation mode.

7 . The control unit ( 100 ) according to claim 1 , wherein the control unit ( 100 ) is configured to provide notification information to a further network node about the side-link resource pool configuration ( 104 ).

8 . The control unit ( 100 ) according to claim 7 , wherein the notification information comprises at least one of:
configuration update notification information for at least one session; resource pool configuration parameters; terminal device-related statistics for the terminal device utilizing side-link resources; configuration update notification information for at least one slice coverage area; Slice-related statistics for the slice utilizing side-link resources.

9 . The control unit ( 100 ) according to claim 8 , wherein the resource pool configuration parameters include at least one of:
session configuration parameters for configuring a terminal device associated to at least one slice; and slice configuration parameters for configuring a geographical area.

10 . The control unit ( 100 ) according to claim 1 , wherein the control unit ( 100 ) is configured to provide the side-link resource pool configuration ( 104 ) to a network node using at least one of X2, XnAP, or F1, and NGAP signaling.

11 . A terminal device ( 700 ) for performing side-link communication, wherein the terminal device ( 700 ) is configured to:
generate a session requirement ( 701 ), the session requirement ( 701 ) including information for configuring a side-link communication for at least one slice ( 101 ); provide the generated session requirement ( 701 ) to the control unit ( 100 ).

12 . A management entity ( 800 ) for managing side-link communication for at least one slice ( 101 ) of a communication network, wherein the management entity ( 800 ) is configured to:
generate an upper layer requirement ( 801 ) for the at least one slice ( 101 ); provide the generated upper layer requirement ( 801 ) to the control unit ( 100 ).

13 . A method ( 900 ) for assisting side-link communication for at least one slice ( 101 ) of a communication network, wherein the method ( 900 ) comprises the steps of:
obtaining ( 901 ), by a control unit ( 100 ), at least one of an upper layer requirement ( 102 ), and a session requirement ( 103 ), configuring ( 902 ), by the control unit ( 100 ), for the at least one slice ( 101 ), at least one side-link resource pool ( 104 ) based on the upper layer requirement ( 102 ) and/or session requirement ( 103 ).

14 . A method ( 1000 ) for performing side-link communication, wherein the method ( 1000 ) comprises the steps of:
generating ( 1001 ), by a terminal device ( 700 ), a session requirement ( 701 ), the session requirement ( 701 ) including information for configuring a side-link communication for at least one slice ( 101 ); providing ( 1002 ), by the terminal device ( 700 ), the generated session requirement ( 701 ) to the control unit ( 100 ).

15 . A method ( 1100 ) for managing side-link communication for at least one slice ( 101 ) of a communication network, wherein the method ( 1100 ) comprises the steps of:
