Abstract: An electronic device may include wireless circuitry. The wireless circuitry may include one or more antenna arrays coupled to baseband processing circuitry by parallel radio-frequency signal (receive) chains. To more efficiently perform beam measurements, and thereby more efficiently determine cell status, beam measurements may be performed by the radio-frequency receive chains in a parallel manner. If desired, beam measurements for one or more inter-frequency and/or intra-frequency layers may each be parallelized. If desired, beam measurements during a discontinuous reception mode of operation may be parallelized.

Abstract: Uplink (UL) data splits between LTE and WLAN can be go supported in cellular networks. The split can be UE controlled or network controlled. Both UE and network controlled bearer split architectures can be supported. The reporting of Uplink Buffer Status (BSR) and the subsequent data allocation can depend on what option is supported by the network. For UE controlled UL data splits, the UE determines a traffic split ratio between LTE and WLAN. The split can be based on local link conditions. For network controlled UL data splits, the network (e.g. a Link Aggregation Scheduler at the eNB) is responsible for making bearer split decisions. The decisions can be based on link qualities, available traffic and quality of service (QoS) requirements of associated users. The split can be based on a per bearer threshold, an eNB configured ratio, or an implicit inference based on a UL grant.

Abstract: Techniques described herein may be used to enable User Equipment (UE) to efficiently and reliably report supported band combinations to a wireless network. An enhanced NodeB (eNB) may determine eNB-supported bands combinations for carrier aggregation scenarios, create a simplified representation of the eNB-supported bands combinations (e.g., using a highest order band combination, groups of band combinations, etc.), and communicate the eNB-supported bands combinations to the UE. The UE may determine UE-supported band combinations that are among the eNB-supported bands combinations, create a simplified representation of the UE-supported band combinations, and communicate the eNB-supported bands combinations to the eNB. The eNB may use the UE-supported band combinations to allocate appropriate carriers to the UE for carrier aggregation.
