Abstract: Apparatuses, systems, and methods for a wireless device to perform a method including performing one or more of periodic beam quality measurements and/or event-based beam quality measurements, determining, based at least in part on one or more of the periodic beam quality measurements and/or the event-based beam quality measurements, a recommended beam quality measurement configuration, and transmitting, to a base station serving the UE, the recommended beam quality measurement configuration. In addition, the UE may perform receiving, from the base station, instructions regarding the beam quality measurement configuration. The instructions may include instructions to activate, deactivate, and/or modify at least one beam quality measurement configuration. In addition, the instructions may be based, at least in part, on the recommended beam quality measurement configuration.

Abstract: Apparatuses, systems, and methods for a wireless device to perform substantially concurrent communications with a next generation network node and a legacy network node. The wireless device may be configured to stablish a first wireless link with a first cell according to a RAT, where the first cell operates in a first system bandwidth and establish a second wireless link with a second cell according to a RAT, where the second cell operates in a second system bandwidth. Further, the wireless device may be configured to perform uplink activity for both the first RAT and the second RAT by TDM uplink data for the first RAT and uplink data for the second RAT if uplink activity is scheduled according to both the first RAT and the second RAT.

Abstract: Apparatuses, systems, and methods for a wireless device to perform methods for configuring a power savings signal in fifth generation (5G) new radio (NR) networks. The wireless device may transmit, to a base station within a network, power savings requirements and receiving, from the base station, a configuration of a power saving signal, where the configuration indicates one or more functionalities of the power saving signal. The wireless device may periodically receive, from the base station, the power saving signal and interpret the power saving signal based on the configuration. The configuration of the power saving signal may be received via radio resource control signaling.

Abstract: This disclosure relates to techniques for a wireless device to dynamically adapt its bandwidth use using network scheduling information in a cellular communication system. A radio resource control connection between a cellular base station and a wireless device may be established. The wireless device may receive network scheduling information from the cellular base station. The wireless device may dynamically select a receive bandwidth for receiving transmissions from the cellular base station based at least in part on the network scheduling information.

Abstract: A method performed by a user equipment (UE) connected to a network that utilizes a first bandwidth for a plurality of network operations and assigns the UE a second bandwidth, within the first bandwidth, to utilize for communication with the network. The method including determining a third bandwidth within the first bandwidth that is narrower than the first bandwidth and wider than the second bandwidth and includes the second bandwidth, monitoring the third bandwidth for at least one reference signal transmitted by the network, and determining at least one value that corresponds to the connection between the UE and the network based on the at least one reference signal.

Abstract: A downlink control information (DCI), such as a blanking DCI (bDCI) message may be transmitted by a base station (e.g., eNB) and received by a mobile device (e.g., UE). The bDCI may indicate that the eNB will not transmit a subsequent DCI to the UE for a duration of time. The UE may be in continuous reception mode or connected discontinuous reception (C-DRX) mode. The UE may therefore determine to enter a sleep state or take other action. The bDCI may specify an explicit blanking duration, or an index indicating a blanking duration from a lookup table, and/or the blanking duration (and/or a blanking duration offset value) may be determined in advance, e.g., semi-statically. When the UE is in C-DRX mode, the UE may be configured such that either the sleep/wake period of the C-DRX mode or the blanking period of the bDCI may take precedence over the other.
