Abstract: A method including receiving at a wireless communication device first and second scheduling information indicative of attributes related to a data transmission. The first scheduling information including information indicative of contents attributes of the data transmission, and the subsequently received second scheduling information being indicative of time attributes of the data transmission.

Abstract: Various communication systems may benefit from signaling that instructs operation of devices. For example, certain wireless communication systems can benefit from signaling of listen-before-talk type for unlicensed spectrum operation. A method can include receiving a mapping between listen before talk type and a set of one or more of downlink ending partial subframe durations. The method can also include receiving indication of at least one downlink ending partial subframe duration of the plurality of downlink ending partial subframe durations. The method can further include determining a listen before talk type based on the received indication and the received mapping. The method can additionally include communicating with at least one access node based on the determined listen before talk type.

Abstract: In an LTE-A mobile communications system, provision of additional random access resources, called “shadow” PRACH, that are available to User Equipments, UEs, for a contention-free access procedure during handover. eNBs provide information on PRACH resources, broadcasting a first set of resources available for contention-based and contention-free random access and indicating via the X2 interface to neighbouring eNBs such additional PRACH resources, together with corresponding preambles, which are in turn indicated via dedicated signalling to UEs during a handover procedure.

Abstract translation: 在LTE-A移动通信系统中，为切换期间的无争用接入过程提供可用于用户设备（UE）的附加随机接入资源（称为“阴影”PRACH）。 eNB提供关于PRACH资源的信息，广播可用于基于竞争和无竞争随机接入的第一组资源，并且经由X2接口向相邻eNB指示这样的附加PRACH资源以及相应的前导码，所述另外的PRACH资源又通过专用 在切换过程期间向UE发送信令。
