Multi-RAT Radio Resource Aggregation with Split Bearer Support

摘要

This disclosure relates to aggregation of radio resources provided according to multiple radio interfaces. According to some embodiments, a base station may establish a radio bearer with a wireless user equipment (UE) device. The radio bearer may initially utilize a first radio interface between the base station and the UE. The base station may receive an indication to aggregate radio resources of an access point that utilizes a second radio interface for the UE. Based on the indication to aggregate radio resources for the UE, the base station may redirect at least a portion of data of the radio bearer by way of the access point to be exchanged with the UE using the second radio interface.

主权项

1. A base station (BS), comprising:
a radio; and a processing element communicatively coupled to the radio; wherein the radio and the processing element are configured to:
establish a radio bearer with a wireless user equipment (UE) device according to a first RAT;determine whether the radio bearer supports offloading to a second RAT and whether the radio bearer supports a split bearer configuration between the first RAT and the second RAT;if the radio bearer supports offloading to the second RAT and radio resources according to the second RAT are available to the UE, offload the radio bearer from the first RAT to the second RAT; andif the radio bearer supports a split bearer configuration between the first RAT and the second RAT and radio resources according to the second RAT are available to the UE, split the radio bearer such that some data of the radio bearer is exchanged between the base station and the UE via the first RAT and some data of the radio bearer is exchanged with the UE via the second RAT.
