Abstract: A method of TDM in-device coexistence (IDC) interference avoidance is proposed. In a wireless communication device, a first radio module is co-located with a second radio module in the same device platform. The first radio module obtains traffic and scheduling information of the second radio module. The first radio module then determines a desired TDM pattern based on the traffic and scheduling information to prevent IDC interference with the second radio module. The first radio module also transmits TDM coexistence pattern information based on the desired TDM pattern to a base station. In one embodiment, the TDM coexistence pattern information comprises a recommended TDM pattern periodicity and a scheduling period to maximize IDC efficiency subject to limited level of IDC interference possibility. In one specific example, the TDM coexistence pattern information comprises a set of discontinuous reception (DRX) configuration parameters defined in long-term evolution (LTE) 3GPP standards.

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.

Abstract translation: CCE +号码分配方法减少了包含LTE（长期演进）系统和LTE +（长期演进高级）系统的混合系统中的ACK / NACK（确认/否定确认）冲突概率。 通过从CCE的CCE号码中选择包含分配在构成CCE +的资源元素区域中的PDCCH（物理下行链路控制信道）的号码来定义CCE（控制信道元素）+号码，其中配置PDCCH +。 这可以防止在同时发送PDCCH和PDCCH +时CCE号和CCE +号的重叠选择，从而可以降低与CCE号和CCE +号相关的ACK / NACK的冲突概率。

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 wireless LAN communication device configured to carry out the priority control of an EDCA scheme includes a first determining section for determining access categories, a second determining section for determining a bandwidth occupancy rate for each access category, and a change section for dynamically changing parameters regarding the priority control for each category in accordance with determination results of the first and second determining sections. Accordingly, even when a mass of traffic exists in categories having the priority of the same class, the collision of packets in the traffic, the increase of the amount of delay, the reduction of throughput, and the like can be avoided.
