Abstract
In a 5G network, an integrated access and backhaul (IAB) deployment in a 5G network, can enable aggregation of multiple user equipment (UE) bearers into backhaul bearers based on factors such as route information of UE bearers and quality of service of UE bearers. Additionally, an adaptation layer can be configured to perform aggregation of data from UE bearers into backhaul bearers either above or below a radio link control layer. Thus, aggregation of data from UE bearers into backhaul bearers can be performed either above the RLC or below the RLC to take advantage of benefits from both options.
Claims20
A method, comprising:
- configuring, by first network equipment comprising a processor, a user plane control stack enabled via a network, wherein the user plane control stack comprises an adaptation layer;
- splitting, by the first network equipment, the adaptation layer into a first adaptation layer and a second adaptation layer, wherein the first adaptation layer is above a radio link control layer, and wherein the second adaptation layer is below the radio link control layer;
- configuring, by the first network equipment, the first adaptation layer to aggregate data packets from user equipments, the data packets being routed from the user equipments to second network equipment that is part of the network;
- and
- in response to configuring the first adaptation layer, configuring, by the first network equipment, the second adaptation layer as a pass-through layer between a media access control layer and the radio link control layer enabled via the network.
A system, comprising:
- a processor;
- and
- a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
- configuring a user plane control stack, wherein the user plane control stack comprises an adaptation layer;
- dividing the adaptation layer into a first adaptation layer and a second adaptation layer, wherein the first adaptation layer is logically above a radio link control network layer, and wherein the second adaptation layer is logically below the radio link control network layer;
- configuring the first adaptation layer to aggregate data packets routed from user equipments to network equipment;
- and
- in response to configuring the first adaptation layer, configuring the second adaptation layer as a pass-through layer between a media access control network layer and the radio link control network layer.
A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:
- configuring a user plane control stack enabled via a network, wherein the user plane control stack comprises an adaptation layer;
- from the adaptation layer, generating a first adaptation layer and a second adaptation layer, wherein the first adaptation layer is generated to be above a radio link control layer of the user plane control stack, and wherein the second adaptation layer is generated to be below the radio link control layer of the user plane control stack;
- configuring the first adaptation layer to aggregate data packets from mobile devices that are routed to network equipment;
- and
- in response to configuring the first adaptation layer, configuring the second adaptation layer as a pass-through layer between a media access control layer and the radio link control layer.
