  • Patent number: 12075437
    Abstract: A user equipment (UE), method and computer program product are provided. A configuration is received to detect a first field within a first DCI, the UE operating in a first state upon reception of the configuration. While operating in the first state where a minimum slot offset is applicable for at least one of receiving data or transmitting data, the UE switches from operating in the first state to a second state responsive to detecting a first state value for the first field in a first control message using the first DCI format in a first slot of a first set of slots. While operating in the second state where the minimum slot offset is not applicable for at least one of receiving the data and transmitting the data, the UE switches from operating in the second state to the first state responsive to detecting a second state value.

  • Publication number: 20230309108
    Abstract: Techniques are provided for skipping or suspending PDCCH monitoring to reduce power consumption in a wireless device and extend battery lifetime. To implement PDCCH skipping, the access node sends a command to the wireless device to suspend PDCCH monitoring for a specified time period following a delay period. The request to suspend PDCCH monitoring, referred to herein as the PDCCH monitoring indication, is sent in DCI. In some embodiments, the length of the delay period and/or the suspension interval can be preconfigured. In other embodiments, the length of the delay period and/or the suspension interval is indicated by the DCI transmitted to the wireless device. In response to the PDCCH monitoring indication, the wireless device suspends PDCCH monitoring for a period spanning one or more PDCCH monitoring occasions following the end of the delay period and remains in a sleep mode or low power mode.

  • Publication number: 20230189251
    Abstract: A wireless device (12) transmits signaling (26) which indicates that the wireless device (12) supports cross-slot scheduling. Support for cross-slot scheduling indicates a range of values that the wireless device (12) supports for a triggering offset (20). A triggering offset (20) is an offset between: (i) a slot containing downlink control information (14) that triggers a set (16) of aperiodic channel state information reference signal, CSI-RS, resources; and (ii) a slot in which the set (16) of aperiodic CSI-RS resources is transmitted. The signaling (26) may enable a network node (15) that receives the signaling (26) to correspondingly transmit, to the wireless device (12), a control message which configures the wireless device (12) with a triggering offset (20) that has a value within the indicated range of values.

  • Publication number: 20230127023
    Abstract: An access node (110) configures a User Equipment, UE (105), with a power saving monitoring pattern, and subsequently transmits a power saving signal configured to switch the UE (105) from monitoring a downlink in accordance with a connected mode discontinuous reception, C-DRX, monitoring pattern to monitoring the downlink in accordance with the power saving monitoring pattern. For each of the monitoring patterns, monitoring the down-link in accordance with the monitoring pattern comprises monitoring the down-link only when a monitoring opportunity of the monitoring pattern is concurrent with a scheduled active interval of a C-DRX configuration of the UE (105). For any C-DRX cycle of the C-DRX configuration, the monitoring of the downlink in accordance with the power saving monitoring pattern has a shorter monitoring duration than the monitoring of the downlink in accordance with the C-DRX monitoring pattern.

  • Publication number: 20230104198
    Abstract: Power savings is achieved by configuring the UE with a sparse search space for power savings and a packed search space for normal PDCCH monitoring. The network is aware of the search space being monitored by the UE and can signal the UE to switch between the two search spaces by sending downlink control information (DCI) to the UE in the search space being monitored by the UE. To conserve power, the network switches the UE to the sparse search space for PDCCH monitoring, which requires less energy than PDCCH monitoring in the packed search space. When the network expects to have downlink data to send, the network sends downlink control information (DCI) to the UE in the sparse search space to cause the UE to switch to the packed search space. The DCI may comprise scheduling information, or a WUS-like signal indicating that the UE should switch search spaces for PDCCH monitoring.
