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.

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: This disclosure relates to performing cellular communication using a control information monitoring framework. A wireless device may monitor a control channel for control information according to a first periodic pattern. According to the first periodic pattern, the wireless device may monitor the control channel in a specified slot during each period of the first periodic pattern. Each period of the first periodic pattern may include multiple slots. The wireless device may receive control information during a first slot. The first slot may be a specified slot according to the first periodic pattern. The control information received during the first slot may schedule a data communication. The wireless device may monitor the control channel for control information in at least one slot that is not specified according to the first periodic pattern based at least in part on receiving control information during a specified slot according to the first periodic pattern.

Abstract: A user equipment (UE) supports communication over a first (lower) frequency range and a second (higher) frequency range. The UE determines an extent of preference of the second frequency range over the first frequency range, e.g., based on one or more of the following: sensor measurements; physical channel measurements; battery conditions; weather conditions; voice call activity; indoor/outdoor/in-car status; learned relationships between previous location-time conditions and performance on the second frequency range; etc. The UE device may control search activity and/or measurement activity on the second frequency range based on the preference extent, e.g., by controlling rates of repetition of search and/or measurement on the second frequency range, or by adding a measurement bias to a measurement reporting threshold, or by adding a delay to a measurement reporting time for a measurement, or by disabling search and measurement on the second frequency range.

Abstract: A base station and mobile device (UE) may coordinate transmission of reference signals and reception of corresponding channel state information (CSI) reports. If a periodic reference signal is scheduled for transmission outside the on-duration period of the UE, even if the reference signal corresponds to a periodic CSI report scheduled to be transmitted by the UE during the on-duration period, the base station may not transmit the periodic reference signal, thereby allowing the UE not to prematurely exit a low-power state. The base station may instead transmit an aperiodic reference signal at a specified point in time later than the scheduled transmission of the periodic reference signal. The UE may receive the aperiodic reference signal and either transmit the periodic CSI report or an aperiodic CSI report in response, depending on how close to the start of the on-duration period the transmission of the periodic CSI report is scheduled.
