摘要： In a multi-RAT user equipment autonomous denials are used to stop LTE transmission to free frames or subframes for the transmission of e.g Bluetooth or WLAN signals. The use of the autonomous denials is limited per defined time period. The start of this time window may not be synchronised between UE and eNB. To avoid any synchronisation problems, a system frame number associated with the network entity is used as the basis for generating an indicator for the start of the time period. The indicator is then transmitted to the user equipment, which is adapted to respond to receipt of the indicator by configuring the user equipment to perform no more than a predetermined number of autonomous denials during the time period. The number of unsuccessful transmissions during the time period is then monitored by the network entity, and resource usage within the wireless communications network is selectively adapted on the basis of the monitoring.

摘要： In an ad hoc network a feedback radio resource maps from a data radio resource to at least one frequency sub-band which the data resource excludes. The feedback resource is also spaced in time from the data resource by a predetermined interval. Feedback (ACK/NACK) for data received in the data resource is then sent in the feedback resource. In various embodiments the sub-band is one or more edges of the data resource channel, or edges of a component carrier. The predetermined interval may be a function of how much of the data resource is occupied by data. The data transmitting device delays sending its data by a time offset from the end of a previous transmission on that channel, or if it does not know the end time it delays until the predetermined interval plus the length of the feedback resource have lapsed. Various synchronization aspects are also disclosed.

摘要： The application relates to a mobile terminal radio stack for D2D single channel (308) and a cellular uplink single channel (324). A D2D connection is a direct connection formed between a first mobile terminal and a second mobile terminal over the cellular radio spectrum. The D2D connection is a local communication link and is generally enabled for use over short distances. Because the D2D connection could be lost quite rapidly, handover (e.g. bearer establishment) of the D2D communications to traditional cellular communications e.g. Evolved Universal Mobile Telecommunications System Terrestrial Radio Access Network (E-UTRAN)) may not occur in time to synchronize the multiple mobile terminals. As a result, multiple protocol data units between the mobile terminals may be lost. This problem is solved in that in response to a handover indication, the mobile terminal may then cause a PDCP entity (318) that is associated with the D2D bearer that is undergoing handover to be associated with an additional RLC entity, such as an RLC entity associated with a cellular bearer, e.g. an Evolved Packet System EPS bearer (334). SDUs received via the logical channel related to the D2D connection (314) and SDUs received via the logical channel related to the cellular connection (334) are then transmitted via the same cellular bearer (330).
摘要翻译：本申请涉及用于D2D单信道（308）和蜂窝上行链路单信道（324）的移动终端无线电堆栈。 D2D连接是通过蜂窝无线电频谱在第一移动终端和第二移动终端之间形成的直接连接。 D2D连接是本地通信链路，通常可以在短距离内使用。因为D2D连接可能相当迅速地丢失，所以将D2D通信与传统蜂窝通信的切换（例如，承载建立）相关联。演进的通用移动电信系统陆地无线电接入网（E-UTRAN））可能不会及时发生以同步多个移动终端。结果，移动终端之间的多个协议数据单元可能丢失。解决的问题在于，响应于切换指示，移动终端然后可以使与正在进行切换的D2D承载相关联的PDCP实体（318）与诸如RLC实体之类的附加RLC实体相关联与蜂窝承载相关联，例如演进分组系统EPS承载（334）。经由与D2D连接（314）相关的逻辑信道接收的SDU和经由与蜂窝连接（334）有关的逻辑信道接收的SDU然后经由相同的蜂窝承载（330）发送。

摘要： A method, apparatus and computer program product are provided herein for enabling a D2D bearer to stay alive even in an instance in which a D2D connection is lost. In some example embodiments, a method is provided that comprises detecting a condition that indicates that a device-to-device bearer is to be terminated. The method of this embodiment may also include modifying a cellular bearer protocol data unit header, such that the cellular bearer protocol data unit header indicates that a cellular bearer service data unit is a device-to-device protocol data unit. The method of this embodiment may also include causing one or more device-to-device protocol data units to be encapsulated within one or more cellular bearer protocol data units, such that the one or more device-to-device protocol data units are transmitted via a cellular bearer.
