  • Patent number: 12150147
    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.

  • Publication number: 20240381256
    Abstract: Systems, methods, processors, and circuitries are provided for configuring, transmitting, receiving and processing single frequency network wake-up signals. In one example a user equipment (UE) includes a radio frequency (RF) transceiver and a baseband processor. The baseband processor is configured to, when executing instructions stored in a memory, cause the UE to receive, via the RF transceiver, a wake-up signal (WUS). The WUS is transmitted by a plurality of cells in a WUS single frequency network (SFN) and each cell of the plurality of cells transmits the WUS in identical time and frequency resources. Based on the received WUS, the baseband processor causes the UE to configure one or more components of the UE to receive a subsequent signal.

  • Publication number: 20240380555
    Abstract: The present application relates to devices and components including apparatus, systems, and methods for UE positioning. In an example, a UE transmits a sounding reference signal for positioning (SRSp) to a base station. The SRSp transmission can use frequency hopping and can rely on a window and/or a collision rule associated with the entire frequency hopping sequence or only a frequency hop of such a sequence. The window and/or collision rule can reduce the potential for signal collision with non-SRSp signals. Further, the UE can implement a low power high accuracy position (LPHAP) technique. In this technique, a fallback behavior or an SRSp transmission can be stopped if the UE is not able to accurately measure ā€œNā€ configured reference signals, where ā€œNā€ can be based on the positioning method.
