Abstract: In one embodiment, a particular node in a wireless network may receive a wireless signal, and may determine whether the wireless signal is intended for itself. In response to determining that the wireless signal is intended for the particular node, the particular node may transmit a non-colliding wireless carrier sense detected alert (CSDA) signal during the received wireless signal to request that other nodes within communication distance of the particular node refrain from transmitting for a duration of the received wireless signal. In another embodiment, a node listens on a first frequency for a wireless CSDA signal regarding a second (colliding) frequency, and in response to receiving a CSDA signal, may refrain from transmitting a wireless signal on the second frequency for the particular duration, or else (if not receiving a CSDA signal), may allow transmission of a wireless signal on the second frequency, accordingly.

Abstract: An Intelligent Transportation Systems (ITS) device is described. The ITS device (400) includes: radio resources including a receiver (402) adapted to receive a radio signal in at least two frequency bands; a channel detector (410) arranged to analyse a signal received in a first frequency band to determine the presence of a transmission in that frequency band; a controller (402) configured to control assignment of radio resources, and in the event that the channel detector detects a signal in the first frequency band, to prevent transmission of a potentially interfering radio signal. The first frequency channel can be part of another radio communications system, such as a RTTT1 SSRC radio system.

Abstract: A CCE+ number allocation method reduces the ACK/NACK (Acknowledgment/Negative Acknowledgment) collision probability in a mixed system containing an LTE (Long Term Evolution) system and an LTE+ (Long Term Evolution Advanced) system. A CCE (Control Channel Element)+ number is defined by selecting a number from CCE numbers of the CCE to contain PDCCH (Physical Downlink Control Channel) allocated in a resource element region constituting CCE+ where PDCCH+ is arranged. This can prevent overlapped selection of the CCE number and the CCE+ number even when the PDCCH and the PDCCH+ are simultaneously transmitted, thus making it possible to reduce the collision probability of ACK/NACK correlated to the CCE number and the CCE+ number.
