Abstract: An electronic device includes a communication device, a connected mode discontinuous reception (C-DRX) module operable with the communication device, and one or more processors operable with the communication device and the C-DRX mode of operation. The one or more processors infer whether network congestion exceeds a predefined threshold from one or more Internet-protocol (IP) and physical layer metrics and disabling the C-DRX mode of operation when the network congestion exceeds the predefined threshold. The one or more processors can also disable the C-DRX mode of operation when user-identified “performance” applications are operating on the one or more processors.

Abstract: A communication device, method, and computer program product reduce power consumption when one or more transmit chains can be inactivated without unsatisfactory uplink communication quality in single data layer transmit diversity (TxDiv) or multiple input multiple output (MIMO) mode. The communication device monitors uplink signal quality of the uplink data stream while connected in single layer mode to a base node using multiple transmit chains. The controller device deactivates transmit chain(s) while the uplink signal quality remains satisfactory. The controller re-activates the inactivated transmit chain(s) in response to the uplink signal quality becoming unsatisfactory.

One or more processors then select, in response to the one or more sensors detecting the triggering event, a quantity of antenna elements from the plurality of antenna elements available for engagement in the MIMO communication across the network as a function of the radiation correlation pattern.

Abstract: A communication system, a method, and a computer program product provide selecting and camping on primary band in idle mode in preparation for supporting a predicted data connection for demanding application(s) to a network system. The prediction is based on trigger event(s) that include one or more of a configuration of a communication system, context of use of the communication system, and user interaction with the at least one user interface device. A controller of the communication system identifies, selects, and camps on a combination of a primary band and at least one secondary band of the one or more available network nodes that satisfies a communication demand requirement for the demanding application(s) using carrier aggregation and/or dual connection in preparation for activation of the demanding application(s) and establishment of the data connection with the communication network.

The communication system identifies a combination of a primary band and secondary band(s) of the available network node(s) that satisfies a communication demand requirement of data throughput, data latency, and/or data quality.

Abstract: A communication device, method, and computer program product provide power efficient transmit diversity using two transmit chains to meet a transmit power level for an uplink signal when one transmit chain is insufficient. In response to determining that the first transmit power level is equal to or less than the transmit power capability of at least one of a first transmit chain and a second transmit chain, the communication device configures a corresponding one of the first transmit chain and the second transmit chain to transmit the uplink channel with at least the first transmit power level.

Abstract: A communication device, method and computer program product provide efficient average power tracking (APT) powering of transmit power amplifiers with fewer switching mode power supplies (SMPSs) to reduce size and cost of the communication device. A controller of the communication device detects an output voltage level of a battery supply of a communication device power amplifiers (PAs) assignable to respective transmit uplinks. The communication device includes a smaller second number of switching mode power supplies (SMPSs). The communication device includes linear regulator(s) that are powered by one of (i) output voltage of the battery supply and (ii) one of the one or more SMPSs. Controller selects a combination of SMPSs and linear regulators to power active PAs. The controller determines APT supply voltage value for each PAs and assigns the SMPS(s) and the linear regulator(s) to the PAs to achieve a highest overall or combined system power efficiency.
