  • CONDITIONS FOR TRANSITIONING TO OR REMAINING IN INACTIVE STATE
    Publication number: 20240080927
    Abstract: A wireless communication device, WCD, receives a message from a network node in a communication network. The message indicates that the WCD is to save a user equipment, UE, context of the WCD. In response to receiving the message, the WCD saves the UE context. The message also indicates that the WCD is to transition from a connected state to an inactive state when a first condition is satisfied, and/or remain in an inactive state when a second condition is satisfied. The first and/or second condition may for example include that the WCD experiences a loss of connection or loss of coverage, or that the WCD experiences a radio link failure.

  • Network Node, Wireless Communication Device and Methods for Configuring Side-Link Resources in Wireless Communication Network
    Publication number: 20240063958
    Abstract: A network node, a wireless communication device and methods therein for monitoring interferences between a number of groups of wireless communication devices and configuring SL resources for the number of groups of wireless communication devices in a wireless communication network are disclosed. The network node configures a discovery signal associated with an identity and configures which wireless communication devices in which groups to transmit and/or receive the configured discovery signal. The network node determines whether the number of groups of wireless communication devices (130, 131, 132, 140, 141, 142) are isolated from each other based on a report related to the discovery signal and decides whether or not to reconfigure the SL resources for the number of groups or rearrange the wireless communication devices in the groups based on the determined result on whether the number of groups of wireless communication devices (130, 131, 132, 140, 141, 142) are isolated from each other.

    Publication number: 20230422164
    Abstract: Embodiments herein relate to a method performed by a radio unit (101) for controlling power levels of spatially separated transceivers (110-119) connected to the radio unit (101) via corresponding antenna ports (a-j). Each transceiver (110-119) is capable of performing measurements on uplink transmissions from wireless devices in a wireless communication network (100). The radio unit (101) receives, from each transceiver (110-119), measurements on uplink transmissions from wireless devices. Then, the radio unit (101) determines, for each transceiver (110-119), a load based on how many wireless devices that have the transceiver as the transceiver with the most relevant measurement for its uplink transmissions. The radio unit (101) also controls a power level of at least one first transceiver (110) based on at least one of the determined loads for the transceivers (110-119). Embodiments of the radio unit (101) are also described.

  • Methods and devices for scheduling group uplink communication
    Patent number: 11844089
    Abstract: Group transmission of data from a group of User Equipment devices to a network node of a cellular communication system where communication between devices is effected by device-to-device technology can provide significant improvements in uplink coverage and user bit rate. However, the benefits of group transmission means that not all devices of a group have sufficient network coverage to reliably receive a grant signal scheduling uplink resources from a network node. Methods, devices and a network node are proposed that enable the dynamic selection of either a direct grant mode, in which each device receives the uplink grant directly from the network, or a relayed grant mode, in which a device acting as group coordinator relays the grant to all members of the group, to ensure optimal performance for group transmissions. The selection is dependent on at least one determined condition relating to the group of devices and/or the group transmission.

  • Random Access in a Wireless Communication Network
    Publication number: 20230389080
    Abstract: A wireless communication device (12) receives a random access configuration (18) from a radio network node (14) configured to transmit multiple SSBs (16-1 . . . 16-N). The random access configuration (18) configures the wireless communication device (12) with a set (20) of one or more random access preambles. This set (20) of one or more random access preambles is not associated with any of the multiple SSBS (16-1 . . . 16-N). Upon receiving a random access preamble from this set, the radio network node (14) may transmit a random access response as a response to the random access preamble. The radio network node (14) may do so by transmitting the random access response on one or more downlink beams that are estimated from measurement of an uplink beam or uplink signal from the wireless communication device (12).

  • Methods and apparatuses for handling the configuration of measurements to be performed by a user equipment in a wireless communication network
    Patent number: 11832138
    Abstract: A method performed by a first base station, is described. The first base station determines a change in one or more measurements to be performed by a UE. The measurements are associated with a first set of frequencies. The first base station also transmits a first message to a second base station comprising information regarding which frequencies in the first set are to be changed. The first base station and the second base station serve the UE. A method performed by the second base station is also described whereby the second base station receives the first message. In a method performed by the UE, the UE receives, from the first base station, a configuration message configured to specify the measurements to perform and a measurement gap configuration. The UE then takes the measurements based on the configuration message.
