摘要： A first wireless node of a wireless communication system is associated with a first cell having a first cell identity. The first wireless node obtains information relating to a set of wireless nodes which use at least one overlapping communication resource that is also used by at least one second node in the first cell. The first wireless node generates a preamble containing: a first data field designating the first cell identity, and a second data field reflecting a respective identity of the wireless nodes in the set of wireless nodes which use the at least one overlapping communication resource. The first wireless node transmits a preamble signal containing the preamble, over a predefined set of resources in a shared resource structure of the wireless communication system thus informing about the wireless nodes that use overlapping communication resources.

摘要： Method for performing an unscheduled uplink transmission by a user equipment UE, in an unlicensed portion of a radio spectrum, the method comprising: performing, by the UE, a listen before talk, LBT, operation in the unlicensed portion of the radio spectrum, wherein the LBT operation includes sensing the portion of the radio spectrum for a pre-determined minimum amount of time for traffic; and performing, if no traffic was sensed, the unscheduled uplink transmission, by the UE, of data in an unscheduled mode of operation for at least one transmission burst.

摘要： A wireless device (100) is configured for dual mode V2X communications over multiple short range radio interfaces. The wireless device (100) is configured to transmit ITS messages over a first short range radio interface configured to operate according to a first communication standard (e.g. PC5 or IEEE 802.11p), and to receive ITS messages over both the first short range radio interface and a second short radio interface configured to operate according to a second communication standard. Implementing the transmitter chain of only one technology, either PC5 or IEEE 802.11p, at each wireless device (100) reduces complexity and mitigates co-channel and adjacent channel interference that is caused by uncoordinated and concurrent transmissions of different technologies from the same wireless device. Implementing receiver chains for both PC5 and 802.11p allows the wireless device (100) to receive signals in the ITS frequency band regardless of which technology the transmitting device is using.

摘要： A scheduling node assigns search space configurations to wireless devices to facilitate power-efficient operation of the wireless devices and the scheduling node. In an example method, a scheduling node configures (810) each of a plurality of wireless devices with two or more respective search space configurations for monitoring for scheduling messages, the two or more respective search space configurations for each wireless device differing with respect to at least one of sparsity in time of scheduling occasions, time offset of scheduling occasions, and duration of scheduling occasions. This configuring comprises assigning (815) search space configurations to the plurality of wireless devices such that a first subset of the assigned search space configurations have a first time offset and a second subset of the assigned search space configurations have a second time offset.
