摘要： A technique of selectively transmitting a skip signal indicative of skipping a downlink control channel from an access node (100; 600; 712; 820) to a radio device (791; 792; 830) is provided. As to a method aspect, a method (200) of selectively transmitting a skip signal indicative of skipping a downlink control channel comprises or initiates determining (202), for the radio device (791; 792; 830), whether a criterion for at least one of skipping the downlink control channel and transmitting the skip signal indicative of skipping the downlink control channel is fulfilled. The method (200) further comprises or initiates transmitting (204), to the radio device (791; 792; 830), the skip signal indicative of skipping the downlink control channel if the criterion has been determined (202) to be fulfilled for a predefined duration.

摘要： A user equipment (UE) is configured to calibrate a receiver during operation in a wireless network. The UE comprises a radio transceiver configured to communicate with the wireless network; and processing circuitry operatively associated with the radio transceiver. The transceiver is arranged to receive a first reference signal associated with a first reception condition, receive a second reference signal associated with a second reception condition, and then either receive a third reference signal, when the processing circuitry determines that the conditions of the first and second reception conditions differ above a first threshold, and receive a message with receiver settings based on reception conditions of the third reference signal, or receive the message with a receiver setting based on receiver conditions of any one of the first and the second reference signals, when the processing circuitry determines that the conditions of the first and second reception conditions differ below the first threshold, enabling omitting reception of the third reference signal. A method and computer program are also disclosed.

摘要： Embodiments include methods, performed by a user equipment (UE), for receiving tracking reference signals, TRS, in a wireless network. An example method comprises receiving, from 5 the network node, system information including a configuration for tracking reference signals, the configuration specifying a plurality of occasions at which the network node may transmit tracking reference signals, where the system information further specifies at least a first window in which availability information for a tracking reference signal according to the configuration will be signaled. The example method further comprises receiving the availability information 0 during the at least a first window, and determining whether a tracking reference signal is available, based on the received availability information.

摘要： A method of signal block reception with automatic gain control (AGC) for a receiver is disclosed. The receiver is configured for at least a sleep mode and an active mode. The signal blocks are non-adjacent in time, and each signal block is configured to be received in entirety using a valid AGC setting determined based on a previous signal block. The method comprises, when switching from the sleep mode to the active mode for continuous reception of a signal block, receiving a first set of samples of the signal block, determining an applicable AGC setting based on the first set of samples of the signal block, and receiving a second set of samples of the signal block using the applicable AGC setting determined based on the first set of samples. Corresponding apparatus, receiver, wireless communication device and computer program product are also disclosed.

摘要： Methods and apparatus are described for adapting wake-up signal monitoring to optimize power saving performance. In one embodiment, a UE can be configured to selectively skip WUS monitoring based on a current UE context. In another embodiment, WUS/PDCCH monitoring and/or other UE procedure can be adapted based on a statistic related to the wake-up signals transmitted by the base station to the UE.

摘要： A method (1200) by a wireless device (110) includes receiving (1202), from a network node (160), a paging early indicator, PEI, configuration that includes an indication of a mapping of a PEI to a plurality of paging occasions, POs. The wireless device receives (1204) the PEI from the network node. Based on the mapping of the PEI to the plurality of POs, the wireless device monitors (1206) a shared channel during the plurality of POs.

摘要： Systems and methods for employing a paging early indicator (PEI) for power savings in an idle mode wireless communication device. In one embodiment, a method performed by a wireless communication device comprises receiving, from a network node, information that configures one or more PEI occasions prior to a paging occasion (PO) of the wireless communication device and making a determination as to whether to monitor for a PEI in the one or more PEI occasions or to skip monitoring for a PEI in the one or more PEI occasions. The method further comprises either monitoring for a PEI in the one or more PEI occasions or skipping monitoring for a PEI in the one or more PEI occasions, in accordance with the determination. In this manner, utilization of PEI monitoring at the wireless communication device is optimized to achieve UE power savings.

摘要： The present disclosure provides a method performed by a network node in a radio access network (RAN) for selective paging of a plurality of user equipments (UEs) operating in a cell served by the network node. The method comprises assigning the plurality of UEs to a plurality of paging subgroups based on one or more operating parameters of the respective UEs, wherein the paging subgroups are associated with a first sequence of paging occasions (POs) to which all of the UEs are assigned. The method comprises transmitting a paging indicator during a particular PO of the first sequence. The paging indicator indicates which of the paging subgroups associated with the particular PO should receive a paging message from the network node. The method further comprises transmitting the paging message within the cell.
