摘要： Method performed by a first node (101). The method is for handling a co-existence of one or more second nodes (102) and a third node (103). The first node (101) and the one or more second nodes (102) operate in a wireless communications network (100). The one or more second nodes (102) and the third node (103) operate in a shared spectrum. The first node (101) determines (303) an area wherein at least a first set of the one or more second nodes (102) are to refrain from transmitting. The determining (303) of the area is based on one or more first indications from the one or more second nodes (102). The one of more first indications are based on a location of the third node (103). The first node (101) initiates sending (305) a second indication to at least the first set of the one or more second nodes (102). The second indication indicates that the second nodes in the first set are to refrain from transmitting.

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.

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 first wireless node (100) of a wireless communication system is associated with a first cell having a first cell identity (CID1). The first wireless node (100) obtains information relating to a set of wireless nodes (300, 400, 500) which use at least one over¬ lapping communication resource that is also used by at least one second node (200) in the first cell. The first wireless node (100) generates a preamble (P) containing: a first data field (F1) de¬ signating the first cell identity (CID1), and a second data field (F2) reflecting a respective identity (ID300, ID400, ID500) of the wireless nodes (300, 400, 500) in the set of wireless nodes which use the at least one overlapping communication resource. The first wireless node (100) transmits a preamble signal (S[P]) containing the preamble (P), over a predefined set of resources in a shared resource structure of the wireless communication system thus informing about the wireless nodes (300, 400, 500) that use overlapping communication resources.
