Device information in a context setup request
Apparatuses, methods, and systems are disclosed for transmitting and/or receiving device information in a context setup request. One method ( 800 ) includes transmitting ( 802 ) a context setup request to a first device. The context setup request includes information corresponding to a second device. The method ( 800 ) includes receiving ( 804 ) a response to the context setup request.
1. A method performed by a central unit (CU) of a base station in an integrated access and backhaul (IAB) system, the method comprising: transmitting a user equipment (UE) context setup request to a first IAB node, wherein the UE context setup request comprises information corresponding to a second IAB node, the information is used to assist in switching between the first IAB node and the second IAB node, the information comprises a one-bit indicator, and the one-bit indicator is equal to zero if the second IAB node is a user device, and the one-bit indicator is equal to one if the second IAB node is a backhaul node; and receiving, from the second IAB node, a response to the UE context setup request.
2. The method of claim 1 , wherein the information comprises a number of user devices served by the second IAB node, a number of nodes served by the second IAB node, or a combination thereof.
3. The method of claim 1 , wherein the information comprises a maximum aggregated bit rate for downlink, a maximum aggregated bit rate for uplink, or a combination thereof.
4. The method of claim 1 , wherein the information comprises a backhaul node identifier, a distributed unit identifier, or a combination thereof corresponding to the second IAB node.
5. The method of claim 1 , wherein the information corresponds to a backhaul node and indicates to the first IAB node that the second IAB node is the backhaul node.
6. A central unit (CU) of a base station in an integrated access and backhaul (IAB) system, the CU comprising: at least one memory; and at least one processor coupled with the at least one memory and configured to cause the CU to:transmit a user equipment (UE) context setup request to a first IAB node, wherein the UE context setup request comprises information corresponding to a second IAB node, the information is used to assist in switching between the first IAB node and the second IAB node, the information comprises a one-bit indicator, and the one-bit indicator is equal to zero if the second IAB node is a user device, and the one-bit indicator is equal to one if the second IAB node is a backhaul node; and receive, from the second IAB node, a response to the UE context setup request.
7. The CU of claim 6 , wherein the information comprises a number of user devices served by the second IAB node, a number of nodes served by the second IAB node, or a combination thereof.
8. The CU of claim 6 , wherein the information comprises a maximum aggregated bit rate for downlink, a maximum aggregated bit rate for uplink, or a combination thereof.
9. The CU of claim 6 , wherein the information comprises a backhaul node identifier, a distributed unit identifier, or a combination thereof corresponding to the second IAB node.
10. A method performed by a first integrated access and backhaul (IAB) node in an IAB system, the method comprising: receiving a user equipment (UE) context setup request from a central unit (CU) of a base station, wherein the UE context setup request comprises information corresponding to a second IAB node, the information is used to assist in switching between the first IAB node and the second IAB node, the information comprises a one-bit indicator, and the one-bit indicator is equal to zero if the second IAB node is a user device, and the one-bit indicator is equal to one if the second IAB node is a backhaul node; and transmitting a response to the UE context setup request.
11. The method of claim 10 , wherein the information comprises a number of user devices served by the second IAB node, a number of nodes served by the second IAB node, or a combination thereof.
12. The method of claim 10 , wherein the information comprises a maximum aggregated bit rate for downlink, a maximum aggregated bit rate for uplink, or a combination thereof.
13. The method of claim 10 , wherein the information comprises a backhaul node identifier, a distributed unit identifier, or a combination thereof corresponding to the second IAB node.
14. A first integrated access and backhaul (IAB) node in an IAB system, the first IAB node comprising: at least one memory; and at least one processor coupled with the at least one memory and configured to cause the first IAB node to: receive a user equipment (UE) context setup request from a central unit (CU) of a base station, wherein the UE context setup request comprises information corresponding to a second IAB node, the information is used to assist in switching between the first IAB node and the second IAB node, the information comprises a one-bit indicator, and the one-bit indicator is equal to zero if the second IAB node is a user device, and the one-bit indicator is equal to one if the second IAB node is a backhaul node; and transmit a response to the UE context setup request.
