Abstract

Methods and apparatus are provided for providing system information to a remote/evolved remote UE (26) as well as methods and apparatus for a remote/evolved remote UE (26) to receive system information.

First claim

What is claimed is:

1. A UE-to-Network Relay (UTNR) node comprising a radio access network, the UTNR node comprising:
receiver circuitry configured to receive, from a remote UE over a non-Uu radio interface:
a request message including request message content corresponding to category information of the remote UE;
a request message including request message content corresponding to an identification of type(s) of system information for the remote UE;

processor circuitry configured to generate a response message; and
transmitter circuitry configured to transmit the response message to the remote UE over the non-Uu radio interface, wherein
in a case that the request message content corresponding to the category information of the remote UE is received, the processor circuitry is configured to generate the response message including system information determined based on a predetermined relation with the category information, and
in a case that the request message content corresponding to the identification of the type(s) of the system information for the remote UE is received, the processor circuitry is configured to generate the response message including system information corresponding to the identification of the type(s) of the system information for the remote UE.

2. The node of claim 1 , wherein the request message content corresponding to the identification(s) of the type(s) of the system information for the remote UE comprises a list of one or more system information blocks.

3. The node of claim 1 , wherein the receiver circuitry is further configured to obtain system information over a Uu interface from a base station node of the radio access network during a system information acquisition window comprising plural repetitions of transmission of the system information over the Uu interface.

4. A user equipment (UE) comprising:
processor circuitry configured to generate a request message including request message content, the request message content corresponding to either category information of the UE or an identification of type(s) of system information for the UE;
transmitter circuitry configured:
to transmit, to a UE-to-Network Relay (UTNR) node over a non-Uu interface, the request message including the request message content corresponding to the category information of the UE;
to transmit, to the UE-to-Network Relay (UTNR) node over the non-Uu interface, the request including the request message content corresponding to the identification of type(s) of system information for the UE; and

receiver circuitry configured to receive, from the UE-to-Network Relay (UTNR) node over the non-Uu interface, a response message, wherein
in a case that the request message content corresponding to the category information of the UE is transmitted, the response message includes system information determined based on a predetermined relation with the category information, and
in a case that the request message content corresponding to the identification of the type(s) of the system information for the UE is transmitted, the response message includes system information corresponding to the identification of the type(s) of the system information for the remote UE.

5. The user equipment (UE) of claim 4 , wherein the request message content corresponding to the identification of the type(s) of the system information for the UE comprises a list of one or more system information blocks.

6. The user equipment (UE) of claim 4 , wherein the non-Uu interface is a PC5 interface.

7. The user equipment (UE) of claim 4 , wherein the non-Uu interface is a non-3GPP interface.

8. A method of a UE-to-Network Relay (UTNR) node comprising a radio access network, the method comprising:
receiving, from a remote UE over a non-Uu radio interface;
a request message including request message content corresponding to category information of the remote UE;
a request message including request message content corresponding to an identification of type(s) of system information for the remote UE;

generating a response message; and
transmitting the response message to the remote UE over the non-Uu radio interface, wherein
in a case that the request message content corresponding to the category information of the remote UE is received, the response message including system information determined based on a predetermined relation with the category information is generated, and
in a case that the request message content corresponding to the identification of the type(s) of the system information for the remote UE is received, the response message including system information corresponding to the identification of the type(s) of the system information for the remote UE is generated.

9. The method of claim 8 , wherein the request message content corresponding to the identification(s) of the type(s) of the system information for the remote UE comprises a list of one or more system information blocks.

10. The method of claim 8 , further comprising:
obtaining system information over a Uu interface from a base station node of the radio access network during a system information acquisition window comprising plural repetitions of transmission of the system information over the Uu interface.

11. A method of a user equipment (UE) comprising:
generating a request message including request message content, the request message content corresponding to either category information of the UE or an identification of type(s) of system information for the UE;
transmitting, to a UE-to-Network Relay (UTNR) node over a non-Uu interface, the request message including the request message content corresponding to the category information of the UE;
transmitting, to the UE-to-Network Relay (UTNR) node over the non-Uu interface, the request including the request message content corresponding to the identification of type(s) of system information for the UE; and
receiving, from the UE-to-Network Relay (UTNR) node over the non-Uu interface, a response message, wherein
in a case that the request message content corresponding to the category information of the UE is transmitted, the response message includes system information determined based on a predetermined relation with the category information, and
in a case that the request message content corresponding to the identification of the type(s) of the system information for the UE is transmitted, the response message includes system information corresponding to the identification of the type(s) of the system information for the remote UE.

12. The method of claim 11 , wherein the non-Uu interface is a PC5 interface.

13. The method of claim 11 , wherein the non-Uu interface is a non-3GPP interface.
