    • A method, a computer program product, and an apparatus are provided. In one configuration, the apparatus transmits a first broadcast signal including information indicating an intention to use a unicast resource for a broadcast. In addition, the apparatus transmits a second broadcast signal in the unicast resource. In another configuration, the apparatus, which is a first wireless device, receives a first broadcast signal from a second wireless device including information indicating an intention to use a unicast resource for a broadcast. In addition, the apparatus receives a first scheduling signal from the second wireless device in a scheduling resource. The first scheduling signal is for indicating a second intention to use the unicast resource for transmitting a second broadcast signal. Furthermore, the apparatus refrains from transmitting a second scheduling signal in the scheduling resource in response to the first scheduling signal.
    • 提供了一种方法,一种计算机程序产品和一种装置。 在一个配置中,该装置发送包括指示广播使用单播资源意图的信息的第一广播信号。 另外,该装置在单播资源中发送第二广播信号。 在另一种配置中,作为第一无线设备的装置从第二无线设备接收包括指示使用单播资源用于广播的意图的信息的第一广播信号。 另外,该设备在调度资源中从第二无线设备接收第一调度信号。 第一调度信号用于指示使用单播资源发送第二广播信号的第二意图。 此外,该装置响应于第一调度信号而避免在调度资源中发送第二调度信号。

    • Various embodiments, relate to a communications system in which communications devices of users and communications devices of vehicular systems communicate safety messages through a cellular communications band or the DSRC (Dedicated short-range communications) vehicular communications band or a combination of both. Various methods and apparatus are directed to communicating safety messages between vehicles and pedestrians/cyclists through the use of a cell phone, thus improving the impact of vehicular communications. In some embodiments, at least some cell phones in a communications system includes both a DSRC communications capability and a cellular communications capability.
    • 各种实施例涉及通信系统,其中用户的通信设备和车载系统的通信设备通过蜂窝通信频带或DSRC(专用短程通信)车载通信频段或二者的组合来传送安全消息。 各种方法和装置涉及通过使用手机来传达车辆与行人/骑自行车者之间的安全消息,从而改善车辆通信的影响。 在一些实施例中,通信系统中的至少一些蜂窝电话包括DSRC通信能力和蜂窝通信能力两者。

    • A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus generates a codeword, determines at least one puncture to the codeword based on allowing a legacy receiver to decode the codeword without knowledge of the at least one puncture, replaces each of the at least one puncture with a pilot, and transmits the codeword. The apparatus may also generate an IEEE 802.11 codeword having pilots in a first set of subcarriers, and puncture the codeword with additional pilots unknown to a legacy receiver in a second set of subcarriers. Accordingly, when an original set of pilot symbols is insufficient or inappropriately placed in a resource structure, a codeword may be transmitted with a new pilot structure capable of being decoded by legacy receivers not aware of the new pilot structure.
    • 提供了一种用于无线通信的方法,装置和计算机程序产品。 该装置产生码字,基于允许传统接收机在不知道至少一个穿孔的情况下对码字进行解码,确定至少一个穿刺码字,用导频代替至少一个穿孔中的每一个,并发送该码字。 该装置还可以生成在第一组子载波中具有导频的IEEE 802.11码字,并且在第二组副载波中对传统接收机未知的附加导频进行穿孔。 因此,当原始的导频符号集合不足或不适当地放置在资源结构中时,可以用能够被不知道新导频结构的传统接收机解码的新导频结构来发送码字。
