Abstract

Systems, apparatuses, and methods are described for wireless communications. A base station and wireless device may communicate capability information associated with a wireless device. The capability information may include information indicating support for an Ethernet type packet data unit session or header parameter compression. An Ethernet type packet data unit session may be instantiated based on the capability information.

First claim

1 . A method comprising:
sending, by a wireless device to a core network, a wireless device capability parameter indicating whether the wireless device supports an Ethernet session type between the wireless device and the core network; receiving, by the wireless device, a first message comprising one or more configuration parameters for a session of the Ethernet session type; and sending, by the wireless device, a second message associated with the session.

2 . The method of claim 1 , wherein the wireless device capability parameter comprises a binary parameter, and wherein the wireless device capability parameter is set to a first value based on the wireless device supporting the Ethernet session type.

3 . The method of claim 1 , wherein the wireless device capability parameter comprises at least one indication field indicating at least one of:
a transmission bit rate, multiple Ethernet addresses for the wireless device, or an Ethernet standard version.

4 . The method of claim 1 , wherein the one or more configuration parameters comprise at least one bearer configuration parameter of a bearer for the session of the Ethernet session type,
wherein the at least one bearer configuration parameter comprises an Ethernet header compression parameter, wherein the method further comprises compressing, by the wireless device and based on the Ethernet header compression parameter, an Ethernet header of the second message, and wherein the sending the second message comprises sending, by the wireless device to a base station via at least one resource block of at least one cell of the base station, the second message comprising the compressed Ethernet header.

5 . The method of claim 1 , wherein the sending the wireless device capability parameter comprises sending, to the core network via a base station, at least one non-access stratum parameter comprising the wireless device capability parameter, and
wherein the non-access stratum parameter further comprises a packet data unit (PDU) session type parameter indicating a type of a requested PDU session.

6 . The method of claim 1 , wherein the first message comprises a radio resource control (RRC) message indicating addition of a bearer for the session of the Ethernet session type, and wherein the second message is further associated with the bearer.

7 . The method of claim 1 , wherein the core network comprises an access and mobility function (AMF) device and a user plane function (UPF) device, and wherein the sending the wireless device capability parameter comprises sending, by the wireless device to the AMF device via a base station, the wireless device capability parameter indicating whether the wireless device supports the Ethernet session type between the wireless device and the UPF device.

8 . The method of claim 1 , wherein the Ethernet session type comprises an Ethernet packet data unit (PDU) session type, and wherein the session comprises a PDU session of the Ethernet PDU session type, and
wherein the second message comprises at least one Ethernet frame message.

9 . A method comprising:
receiving, by a base station, a wireless device capability parameter indicating whether a wireless device supports an Ethernet session type between the wireless device and a core network; sending, by the base station to the wireless device, a first message comprising one or more configuration parameters for a session of the Ethernet session type; and receiving, by the base station from the wireless device, a second message associated with the session.

10 . The method of claim 9 , wherein the wireless device capability parameter comprises a binary parameter, and wherein the wireless device capability parameter is set to a first value based on the wireless device supporting the Ethernet session type.

11 . The method of claim 9 , wherein the wireless device capability parameter comprises at least one indication field indicating at least one of:
a transmission bit rate, multiple Ethernet addresses for the wireless device, or an Ethernet standard version.

12 . The method of claim 9 , wherein the one or more configuration parameters comprise at least one bearer configuration parameter of a bearer for the session of the Ethernet session type,
wherein the at least one bearer configuration parameter comprises an Ethernet header compression parameter, and wherein an Ethernet header of the second message is compressed based on the Ethernet header compression parameter.

13 . The method of claim 9 , wherein the receiving the wireless device capability parameter comprises receiving, by the base station from the wireless device, at least one non-access stratum parameter comprising the wireless device capability parameter, and
wherein the non-access stratum parameter further comprises a packet data unit (PDU) session type parameter indicating a type of a requested PDU session.

14 . The method of claim 9 , wherein the first message comprises a radio resource control (RRC) message indicating addition of a bearer for the session of the Ethernet session type, and wherein the second message is further associated with the bearer.

15 . The method of claim 9 , wherein the core network comprises an access and mobility function (AMF) device and a user plane function (UPF) device,
wherein the receiving the wireless device capability parameter comprises receiving, by the base station from the wireless device, the wireless device capability parameter indicating whether the wireless device supports the Ethernet session type between the wireless device and the UPF device, and wherein the method further comprises sending, by the base station to the AMF device, the wireless device capability parameter.

16 . The method of claim 9 , wherein the Ethernet session type comprises an Ethernet packet data unit (PDU) session type, and wherein the session comprises a PDU session of the Ethernet PDU session type, and
wherein the second message comprises at least one Ethernet frame message.

17 . A wireless device comprising:
one or more processors; and memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
send, to a core network, a wireless device capability parameter indicating whether the wireless device supports an Ethernet session type between the wireless device and the core network;
receive a first message comprising one or more configuration parameters for a session of the Ethernet session type; and
send a second message associated with the session.

18 . The wireless device of claim 17 , wherein the wireless device capability parameter comprises a binary parameter, and wherein the wireless device capability parameter is set to a first value based on the wireless device supporting the Ethernet session type.

19 . The wireless device of claim 17 , wherein the wireless device capability parameter comprises at least one indication field indicating at least one of:
a transmission bit rate, multiple Ethernet addresses for the wireless device, or an Ethernet standard version.

20 . The wireless device of claim 17 , wherein the one or more configuration parameters comprise at least one bearer configuration parameter of a bearer for the session of the Ethernet session type,
wherein the at least one bearer configuration parameter comprises an Ethernet header compression parameter, and wherein the instructions, when executed by the one or more processors, further cause the wireless device to compress, based on th
