Abstract: Embodiments include methods for a user equipment (UE) configured to receive public warning system (PWS) messages from a radio access network (RAN) comprising a plurality of cells. Such methods include receiving, via a first cell having a first ground coverage and a first aerial coverage, a PWS message having a relevant area within a second ground coverage of a second cell but not within the first ground coverage. Such methods include determining whether the PWS message is applicable to the UE based on a first indication of the relevant area, a second indication of relevant altitudes for the PWS message, a third indication of applicability of the PWS message to aerial UEs, and/or a type of signaling by which the PWS message is received. Other embodiments include complementary methods for RAN nodes and core network (CN) nodes, as well as UEs and network nodes configured to perform such methods.

Abstract: A transmitting UE schedules radio frequency resources for use in a data transmission. The transmitting UE determines the transmission bandwidth, subject to certain restrictions, such as allowed DFT sizes for the UE for a data transmission. The determination may be performed through autonomous resource selection operations and/or may be performed using information received through signaling received from the network node as part of a scheduling grant. The UE further determines the ALLOCATED BANDWIDTH. The ALLOCATED BANDWIDTH can be determined based on the TRANSMISSION BANDWIDTH, which has been determined, using a defined rule. Furthermore, the UE generates and transmits toward a receiving UE a scheduling assignment (SA) that indicates the number or the set of subchannels that are within, and conform to, the ALLOCATED BANDWIDTH which was determined. The UE can then perform the data transmission using the SA indicated number or set of subchannels.

Abstract: Disclosed is a method performed by a first wireless device (110) for device to device communication with a second wireless device (120). The method comprises determining a set of wireless communication resources to reserve for a transmission of data from the second wireless device (120) to the first wireless device (110), and reserving the determined set of wireless communication resources. The method further comprises informing the second wireless device (120) of the set of wireless communication resources determined for the transmission of data from the second wireless device (120) to the first wireless device (110), and receiving, from the second wireless device (120), data transmitted on any of the reserved set of wireless communication resources, or information that the second wireless device (120) is not going to use the reserved set of wireless communication resources.

Abstract: According to some embodiments of inventive concepts, a method may be provided to operate a UE providing sidelink communications with other wireless devices. The method may include scheduling a first transmission from the UE, wherein the first transmission has a first priority. The method may also include scheduling a second transmission from the UE, wherein the second transmission has a second priority, wherein the first priority is greater than the second priority, and wherein the first and second transmissions are scheduled for transmission during a time interval. The method may further include transmitting the first transmission during the time interval, and responsive to determining a violation of a timing limit corresponding to scheduling the first and second transmissions during the time interval and responsive to the first priority being greater than the second priority, dropping transmitting the second transmission during the time interval.

Abstract: The present disclosure is related to User Equipments (UEs) and methods at the UEs for Transmitter (TX) profile based sidelink (SL) communication. A method at a UE for SL communication comprises: determining whether SL Discontinuous Reception (DRX) is to be applied for the SL communication or not at least based on multiple associated TX profiles, at least one of the multiple associated TX profiles being mapped to a feature or a feature group; and performing the SL communication with or without the SL DRX applied at least based on the determination of whether the SL DRX is to be used for the SL communication or not.

Abstract: A wireless communication device (10) determines that a further wireless communication device (10) is configured to switch between an inactive reception state and an active reception state. Based on when the further wireless communication device (10) will be in the active reception state, the wireless communication device (10) determines a candidate set of radio resources. From the candidate set of radio resources, the wireless communication device (10) selects at least one radio resource for a D2D transmission from the wireless communication device (10) to the further wireless communication device (10).

Abstract: A technique for transmitting and receiving data in a radio communication from a second radio device to a first radio device is described. As to a method aspect of the technique, one or more radio resources are determined based on radio signals received at the first radio device. The one or more radio resources comprise at least one spatial stream among different spatial streams receivable at the first radio device. A status message indicative of the one or more determined radio resources is transmitted to the second radio device. The data from the second radio device is received at the first radio device on at least one radio resource depending on the one or more radio resources indicated in the transmitted status message.

Abstract: Methods and apparatus for resource allocation in a D2D network (100) are disclosed for reducing resource collisions among wireless devices (200) engaged in device-to-device (D2D) communications. In D2D communications, each wireless device (200) selects a radio resource for signal transmissions and retains the selected resource until a reselection becomes necessary. During the transmission, the wireless device (200) detects a triggering condition for resource reselection. Responsive to the triggering condition, the wireless device (200) performs resource reselection according to a reselection rule that is designed to reduce resource collisions among wireless devices (200).
