Abstract: A technique, comprising: storing, at a user equipment, information about a sequence of uplink grants for the user equipment to make uplink transmissions via one or more radio channels of a plurality of unlicensed radio channels; and in response to data becoming transmission-ready at the user equipment with one or more intervening uplink grants before the earliest opportunity to attempt to transmit the data via a first unlicensed radio channel currently activated at the user equipment, activating a second unlicensed radio channel, and attempting to transmit the data via the second unlicensed radio channel at an uplink grant of the one or more intervening uplink grants.

Abstract: Systems, methods, apparatuses, and computer program products for event-triggered cross-link interference (CLI) measurement reporting. A method may include receiving a configuration with event triggered reporting from a network element. The configuration may specify criteria for triggering a cross-link interference measurement reporting. The method may also include performing cross-link interference measurements of at least one radio transmission on network configured resources based on the configuration. The method may further include determining whether the criteria has been satisfied based at least on a condition out of a set of conditions identified in the criteria. In addition, the method may include transmitting a measurement report of the cross-link interference measurements to the network element when the condition meets a predefined threshold.

Abstract: There are provided measures for handling of paging messages in communication endpoint to network relaying scenarios. Such measures exemplarily comprise, at a relay terminal connected to a mobile access entity of a cellular network systems, selecting, for a terminal to be relayed, a sidelink communication group of a set of configured sidelink communication groups, monitoring network-served paging indicator resources corresponding to said terminal to be relayed for a network-served paging related identifier indicative of transmission of a network-served paging message and information on network-served paging message resources for said transmission of said network-served paging message, transmitting, if said network-served paging related identifier indicative of transmission of said network-served paging message is detected in said network-served paging indicator resources corresponding to said terminal to be relayed and information indicative of paging of said terminal to be relayed is identified in said network-served paging message transmitted in said network-sewed paging message resources as a result of said monitoring, in inter-terminal paging indicator resources configured for said sidelink communication group and next to said network-served paging message resources including said information indicative of paging of said terminal to be relayed, an inter-terminal paging related identifier indicative of transmission of an inter-terminal paging message and information on inter-terminal paging message resources for said transmission of an said inter-terminal paging message, and transmitting said inter-terminal paging message in said inter-terminal paging message resources for said transmission of said inter-terminal paging message.

Abstract: Techniques are provided for facilitating channel estimation to mitigate cross-link interference between a base station in a first cell and at least one neighbor base station. In the context of a method performed by the base station, an indication for assistance information to support channel estimation is provided from the base station to at least one neighbor base station. The method also includes receiving assistance information from at least one neighbor base station. The method further includes causing a time-frequency muting pattern to be signaled to at least one user equipment in a first cell. The method also includes estimating an interference covariance matrix from an interfering link of the at least one neighbor base station based at least in part on the assistance information and estimating the desired signal based on the interference covariance matrix. Corresponding method, apparatus and computer-readable storage mediums are also provided for a base station.

Abstract: There are provided measures for enabling/realizing support for idle period communication in semi-static channel access. Such measures exemplarily comprise that a user equipment device monitors for presence of a clearance indication provided by a base station device serving the user equipment device, which indicates clearance for communication by the user equipment device in at least one idle period of abase station device frame period, disables communication by the user equipment device in the at least one idle period of the base station device frame period when the monitoring yields absence of the clearance indication, and enables communication by the user equipment device in the at least one idle period of the base station device frame period when the monitoring yields presence of the clearance indication.

Abstract: A transmitter is configured to set a counter to a starting value, sense whether a channel is busy or idle and to update the counter value during sensing. When there is data to be transmitted, the transmitter is configured to determine, based on at least the counter value at a transmit opportunity and a duration the channel has been sensed idle before the transmit opportunity, whether to transmit the data or to continue the sensing the channel to a next transmit opportunity without reset- ting the counter value to the starting value.
