Abstract: A first and second UE are connected via a PC5 unicast link. Both maintain a list of potential Side link relay UEs and agree on a common list of UEs that appear in both lists. When the first UE detects that the second UE has trouble receiving it's transmission, e.g. ack/nack timeout or high level of NACKs, decide to use a third UE from the common list as Side Link relay towards the second UE.

Abstract: A method (400) by a first wireless communication device (101) for controlling D2D communication between a first wireless communication device and a second wireless communication device (103) includes transmitting (402), to the second wireless communication device, a DRX configuration for the D2D communication with the second wireless communication device. The first wireless communication device applies (404) the DRX configuration for the D2D communication with the second wireless communication device and receives (406), from the second wireless communication device, a notification indicating that the DRX configuration is unsuitable. Based on the notification, the first wireless communication device reconfigures (408) the DRX configuration and/or notifying a network node that the applied DRX configuration is unsuitable.

Abstract: A method in a user equipment (UE) (210, 1000, 1100) is disclosed. The method comprises determining (902) that a paging message has been received or that a radio resource control (RRC) state of the UE has changed. The method comprises using (904) a normal measurement mode (105) for a period of time after the paging message has been received or the RRC state of the UE has changed. The method comprises determining (906), based on one or more criteria being satisfied, to enter a relaxed measurement mode (110) after the period of time.

Abstract: A method (300) performed in a network node is disclosed for enabling ProSe operation for a wireless device on a non-serving carrier. The network node serves the wireless device on a cell on a serving carrier. The method (300) comprises: determining (310) whether a target cell on a non-serving serving carrier, on which the wireless device is to perform ProSe operation, is known or unknown to the wireless device, and configuring (320, 330) the wireless device with a first gap configuration for the case that the target cell on the non-serving carrier is known to the wireless device, and with a second gap configuration for the case that the target cell on the non-serving carrier is unknown to the wireless device. A method in a wireless device, a network node, a wireless device, computer programs and computer program products are also disclosed.

Abstract: Method for a user equipment, UE), to communicate with a wireless network via multiple cells. The method includes detecting (1210) failure of a first beam associated with a first cell of the plurality of cells and determining (1230) availability or unavailability of other beams, than the first beam, that are associated with the first cell. The method further includes transmitting (1280), to one of the multiple cells, a message indicating availability or unavailability of the other beams associated with the first cell. The message is transmitted within a first duration (1220) after detecting the failure of the first beam, the first duration based on a maximum time for determining availability of the other beams and on a periodicity of resources allocated for beam failure reporting in the cell where the message is transmitted. Other embodiments include complementary method for a network node, UE and network node configured to perform such method.

Abstract: A wireless device selects, from among at least first and second measurement modes in which measurements are respectively performed on cells belonging to first and second carriers, one or more measurement modes in which to perform a measurement. The one or more measurement modes are selected based on whether criteria is met for relaxed monitoring of a neighbor cell, and on whether the wireless device is configured to perform a positioning measurement. The wireless device performs the measurement in the one or more selected measurement modes.

Abstract: When a wireless device obtains a request for a random access in a cell, based on information relating to at least one type of reference signal, it selects at least one type of reference signal. The wireless device then performs a measurement in said cell using the selected type or types of reference signal. Based on a result of the measurement, the wireless device selects a coverage enhancement level, and it then sends a random access message to the cell using radio resources associated with the selected coverage enhancement level.
