US 10,433,211 B2 · Dynamic link monitoring to resolve imbalance in LAA/LTE radio resource allocation

Abstract

A wireless communication device (UE) may monitor grants received from respective cells associated with one or more first (e.g. licensed) frequency band(s) and one or more second (e.g. unlicensed) frequency band(s). Based on the received grants the UE may determine if an imbalance exists in the radio resource allocation, whereby the UE communicates more than intended in the second frequency band(s). The imbalance may be specified with respect to the ratio or portion of the communications that are conducted in the second frequency band(s) with respect to all wireless communications of the UE. If the UE detects an imbalance, it may transmit a report to the network (e.g. to the base station serving the UE) indicating unfavorable conditions for the UE to be operating in the second frequency band(s). In response, the network may disable the respective cell(s) associated with the second frequency band(s) and/or it may disable carrier aggregation for the UE.

Dependent claims

An apparatus comprising:

a processing element configured to cause a wireless communication device to:
conduct wireless communications according to a first radio access technology (RAT) simultaneously in a first frequency band and in a second frequency band;
detect a radio resource allocation imbalance based at least on the wireless communication device conducting a higher portion than a previously specified portion of the wireless communications in the second frequency band with respect to the first frequency band;
and
in response to detecting the radio resource allocation imbalance, cause a base station serving the wireless communication device to schedule subsequent wireless communications of the wireless communication device in the first frequency band.
