Abstract: Apparatus and methods for channel estimation in a Multimedia Broadcast Multicast Service (MBMS) Single Frequency Network (MBSFN) are disclosed. A representative method includes a wireless communication device receiving multiple frames, each frame including multiple subframes, each subframe including multiple symbols. The wireless communication device determines whether subframes include MBMS data or not. For subframes that include MBMS data, the wireless communication device excludes all or certain symbols of the subframes that include MBMS data from a channel estimation process. The wireless communication device determines whether the subframes include MBMS data based at least in part on a channel impulse response and/or a channel energy response for one or more symbols of the subframes.

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.

Abstract: Apparatuses, systems, and methods for a base station to perform a method construct dynamic hierarchical sub-configurations of bandwidth parts (BWPs) for use in a connected mode discontinuous reception (CDRX) communication session with a user equipment (UE) device. The base station may configure a first BWP at a baseband frequency associated with the CDRX communication session as a default BWP, a second BWP with a wider bandwidth than the first BWP as a transmission BWP, and one or more third BWPs as resting BWPs. The transmission BWP and the one or more resting BWPs may be configured to periodically override the default BWP as the active BWP for a predetermined number of CDRX cycles. The transmission BWP may be utilized, when activated to perform data transmission by UE device, and the one or more resting BWPs may be utilized, when activated, for performing channel measurements.

A wireless device and a cellular base station may establish a cellular link. A receive beam configuration may be selected for the cellular link. A downlink data beam may be received using the selected receive beam configuration. A possible modification to the receive beam configuration may be selected based at least in part on motion sensing information for the wireless device. It may be determined whether the possible modification to the receive beam configuration improves downlink data beam reception. It may be determined whether to modify the receive beam configuration for the cellular link in accordance with the possible modification to the receive beam configuration, for example based on whether the possible modification to the receive beam configuration improves downlink data beam reception.

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: Apparatuses, systems, and methods to dynamically indicate preference for self-contained slots and slot duration by a user equipment device (UE) in communication with a base station (e.g., a gNB) using a 5G NR radio access technology. A UE may determine to send an indication to a gNB indicating a preference for self-contained slots and slot duration for downlink and/or uplink communications utilizing one or more of the physical downlink control channel (PDCCH), the physical downlink shared channel (PDSCH), and/or acknowledgement messaging (ACK/NACK) for downlink communications, and utilizing one or more of the physical uplink control channel (PUCCH), the PDCCH, and/or the physical uplink shared channel (PUSCH) for uplink communications. The configuration of self-contained slots and slot duration for uplink and/or downlink may be based on one or more of average packet size, average packet rate, traffic type and UE processing capabilities.
