Abstract: This disclosure relates to radio link monitoring techniques. According to some embodiments, a wireless device may establish a radio link with a cellular base station according to a radio access technology. The base station may provide reference signals, control signals, and data signals to the wireless device via the radio link. The wireless device may perform radio link monitoring of the radio link using characteristics of decoding performance for one or more of the control signals and the data signals. Performing radio link monitoring of the radio link may include determining whether the radio link is in-sync or out-of-sync and determining whether radio link failure has occurred.

Abstract: This disclosure relates to techniques for fast switching between control channels during a radio resource control connection in a wireless communication system. A cellular base station and a wireless device may establish a radio resource control connection. The base station may provide a physical layer indication to the wireless device of a control channel to monitor for scheduling information. The base station may provide scheduling information to the wireless device on the indicated control channel. The wireless device may monitor the indicated control channel for scheduling information based at least in part on the physical layer indication and may receive the scheduling information provided by the base station on the indicated control channel.

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: This disclosure relates to techniques for efficient idle mode wakeup for wireless devices supporting an enhanced coverage mode and a normal coverage mode in a wireless communication system. A wireless device may camp on a cellular base station in idle mode. The wireless device may monitor a control channel associated with the normal coverage mode during a paging occasion. The wireless device may also monitor a control channel associated with the enhanced coverage mode during the paging occasion if a paging indication is not successfully decoded on the control channel associated with the normal coverage mode.

Abstract: An enhanced listen-before-talk procedure may be performed by a device for efficiently accessing and utilizing available resources. The procedure may include specifying input parameter values pertaining to intended wireless communications of the device, adjusting output parameter values based on the input parameter values and an access history of the device, and determining whether to access at least a portion of the wireless communication resources to conduct the wireless communications, based at least on the output parameter values. The output parameter values may pertain to wireless communication resources accessible to the device, and the access history may keep track of wireless communication resource accesses previously made by the device. Input parameter values may include requested channel occupation time, requested frequency resource, requested transmission power, and/or priority and/or urgency of requested transmission, while output parameter values may include energy detection threshold, contention window size, and/or extended clear channel assessment bypass.

Abstract: This disclosure relates to techniques for estimating baseband power consumption and using the baseband power consumption estimation to select baseband operation features. According to some embodiments, one or more baseband power consumption modifiers occurring during an estimation window may be identified. Baseband power consumption of the wireless device during the estimation window may be estimated based on the identified baseband power consumption modifiers occurring during the estimation window. Baseband data throughput of the wireless device during the estimation window may also be estimated. One or more baseband operation characteristics may be selected based at least in part on the estimated baseband power consumption during the estimation window, possibly in conjunction with the estimated baseband data throughput during the estimation window, current wireless medium conditions, and/or other considerations.

Abstract: Apparatuses, systems, and methods for a wireless device to perform a method including a user equipment device (UE) exchanging communications with a base station to determine one or more scheduling profiles, such as one or more scheduling-power profiles, where a scheduling-power profile may specify one or more parameters associated with UE communication behavior, e.g., one or more constraints on UE communication behavior and/or slot scheduling of UE communications. In addition, the method may include the UE receiving a slot configuration schedule from the base station. The slot configuration schedule may be based on at least one scheduling-power profile of the one or more scheduling-power profiles. Further, the method may include the UE performing communications with the base station based on the at least one scheduling-power profile.
