Abstract: An inventive UE carrier aggregation (CA) capability reporting signalling model allows UEs (30) aggregating large numbers of component carriers to transmit CA-relevant capabilities to the network more efficiently than the current (legacy) signalling model. Rather than reporting CA/MIMO/CSI/NAICS capabilities separately for each supported band combination, including fallback configurations, embodiments of the present invention either report UE Radio Frequency (RF) and Baseband (BB) related capabilities separately, or report them disassociated from CA band configurations. This approach avoids the need to signal the full UE (30) set of capabilities for each of (possibly many) supported band combinations. Furthermore, fallback capabilities are signalled implicitly, eliminating the need to transmit this data.

Abstract: In MIMO wireless communication networks, receiver MIMO antenna parameters are not static over time. For example, the MIMO channel correlation is higher for high frequency bands than for low frequency bands. This variability of the receiver antenna parameters introduces uncertainty based the reported CSI (e.g., CQI, PMI, RI) if the network uses only static assumptions for such antenna parameter values. In embodiments, the UE determines the current status of its receive antenna parameters—such as number, configuration, correlation, and power imbalance—and transmits this information to the network (e.g., serving BS). The network node then based on the received information performs one or more radio operational tasks leading to more efficient use of radio resources and enhanced system performance.

Abstract: The solution presented herein is directed to communication devices having a plurality of circuits that may be configured into a plurality of different receiver configurations (or classes), where each receiver configuration uses a different technique for processing a received signal. The solution presented herein enables the communication device to select at least one receiver configuration/class for processing received signals.

At least one of the receiver configurations in the subset is selected responsive to the determined performance metrics, and in some cases also in response to a scheduled amount of data.

Abstract: Different Out-of-sync thresholds are defined for Radio Link Monitoring by a UE having a selectively enabled advanced receiver feature. When the advanced receiver feature is disabled, the UE monitors received signal quality and compares a signal quality metric to a first threshold developed for a reference receiver. When the advanced receiver feature is enabled, the UE compares the signal quality metric to a second threshold indicating lower signal quality than the first threshold. In either case, if the signal quality meets the respective threshold, the UE goes Out-of-sync. The Out-of-sync UE continues to monitor received signal quality. Regardless of whether the advanced receiver feature is enabled or not, a third threshold, developed for the reference receiver, is applied to determine when to return to In-sync. In one embodiment, the reference receiver enables two antennas, and the advanced receiver feature is enabling four antennas.
