摘要： The present disclosure relates to methods and devices in clustered alarm scenarios. More particularly the disclosure pertains to methods and arrangements for detecting several messages of a preconfigured message type, arriving sequentially in time. This disclosure proposes a method, performed in a radio network node, of detecting several messages of a preconfigured message type. The method comprises detecting SI a first message of the preconfigured message type, the first message being associated with an event. The method further comprises reconfiguring S3, in the radio network node, in response to the detection, at least one radio setting related to detecting further messages of the preconfigured message type and monitoring S4 a radio spectrum for further messages of the preconfigured message type using the reconfigured radio settings.

More particularly the disclosure pertains to methods and arrangements for signal detection systems with sparse synchronization signal rate. According to some aspects, the disclosure relates to a method, performed in a radio network node, of detecting at least one signal transmitted from a wireless device, wherein the radio network node transmits a synchronization signal to the wireless device with a synchronization signal rate. The method comprises determining S2 a period of time that has passed since the most recent transmission of the synchronization signal to the wireless device and configuring S3, in the radio network node, at least one radio setting related to detecting the at least one signal, based on the determined period of time. The method further comprises monitoring S4 a radio spectrum for the at least one signal using the at least one radio setting.

摘要： A wireless communication device (10) configures a first discontinuous reception, DRX, cycle for downlink, DL, communication of the wireless communication device (10) with a wireless communication network. A length of the first DRX cycle is defined in terms of a number of slots in the time domain. Further, the wireless communication device (10) configures a second DRX cycle for device-to-device, D2D, communication performed on resources of at least one resource pool to which a subset of the slots is assigned. A length of the second DRX cycle is defined in terms of a number of the slots from the at least one resource pool. Further, the wireless communication device (10) sets the length of the first DRX cycle and the length of the second DRX cycle under the condition that, for consecutive time periods of fixed length, each time period contains an integer number of the first DRX cycles and an integer number of the second DRX cycles.

摘要： A wireless device, network node and a method for managing a hybrid automatic repeat request (HARQ) process for grant-free uplink access. The method includes transmitting data to a network node during a first time slot corresponding to a first PID according to a first mapping. The method further includes receiving a HARQ feedback signal indicating one of an acknowledgement (ACK), and a non-acknowledgement (NACK), associated with the first PID. When a NACK is received, an indication of a second time slot for a retransmission is received. The data corresponding to the first PID is retransmitted during the second time slot.

摘要： A radio device (20) monitors a contiguous set of radio resources to determine radio resources estimated to be used by one or more other radio devices (30, 40). The radio device (20) selects a first subset of radio resources from the contiguous set according to a first criterion configured to mitigate overlap of the first subset with the radio resources estimated to be used by one or more other radio devices (30, 40). Further, the radio device (20) selects a second subset of radio resources from the contiguous set according to a second criterion configured to mitigate fragmentation of the contiguous set by the selected subset and the radio resources estimated to be used. The radio device (20) sends a first sidelink radio transmission (206) on the first subset. The first sidelink radio transmission (206) indicates a reservation of the second subset. Further, the radio device (20) sends a second sidelink radio transmission (208) on the second subset.
