具体实施方式
下面将参照附图来描述根据本发明实施例的用于免授权的上行链路的信息传输方法及装置。在附图中,相同的参考标号自始至终表示相同的元件。应当理解:这里描述的实施例仅仅是说明性的,而不应被解释为限制本发明的范围。此外,基站可以为固定台(fixed station)、NodeB、eNodeB(eNB)、接入点(access point)、发送点、接收点、毫微微小区、小小区等,在此不做限定。此外,这里所述的用户终端(User Equipment,UE)可以包括各种类型的用户终端,例如移动终端(或称为移动台)或者固定终端,然而,为方便起见,在下文中有时候可互换地使用UE和移动台。
根据本发明实施例提供的用于免授权的上行链路的信息传输方法和装置,用户终端首先向基站发送接入信息,在用户终端接收到基站对接入信息的确收信息后,用户终端再发送业务信息,避免了业务信息的无效传输,从而减少了无线资源的浪费,并且提高了上行频谱效率。
以下,参照图1描述根据本发明一个实施例的由用户终端执行 的用于免授权的上行链路的信息传输方法。图1示出了用于免授权的上行链路的信息传输方法100的流程图。
如图1所示,在步骤S101中,发送用户终端的接入信息。根据本实施例的一个示例,接入信息可以包括前导(preamble)码(也可以称为前导序列或随机接入前导码)和/或上行数据控制信息。
例如,前导码可以包含长度为Tcp的循环前缀CP和长度为Tseq的序列。对于一个基站形成的小区,可以有64个前导码。用户终端在接入基站时从64个前导码中选择一个进行接入,以防止与其他用户终端的接入碰撞。
此外,前导码还可以包含用户终端的标识信息。用户终端的标识信息比如用户终端的ID、用户终端的物理地址(也可以称为Media Access Control(MAC)地址)或其它可以唯一标识用户终端的信息等,以标识用户终端的身份。基站在接收到用户终端的前导码后,可以从前导码中获取用户终端的标识信息,从而识别用户终端的身份。
又例如,上行数据控制信息可以包含用户终端的上行链路控制信道(Uplink Control CHannel,UL CCH)信息。
如上所述,在步骤S101中发送的接入信息可以包括前导码和上行数据控制信息二者。可替换地,在步骤S101中发送的接入信息还可以仅包括前导码和上行数据控制信息中的任意一个。
当接入信息包括前导码和上行数据控制信息时,前导码和上行数据控制信息可以都包含用户终端的标识信息,也可以二者中的一个包含用户终端的标识信息,以标识用户终端的身份。
此外,当接入信息仅包括上行数据控制信息时,上行数据控制信息还可以包含用户终端的标识信息。如上所述,用户终端的标识信息例如用户终端的ID、用户终端的MAC地址或其它可以唯一标识用户终端的信息等,以标识用户终端的身份。基站在接收到用户终端的上行数据控制信息后,可以从上行数据控制信息中获取用户终端的标识信息,从而识别用户终端的身份。
根据本实施例的另一示例,步骤S101中的接入信息还可以包括业务信息的第一调度信息。业务信息在稍后的步骤S103中进一步进 行说明。
根据本实施例的一个示例,第一调度信息可以包括业务信息的调制编码信息、业务信息的重复发送次数信息、业务信息的发射功率控制信息、业务信息的签名信息、业务信息的参考信号信息和业务信息的无线资源信息中的至少一个。基站在接收到第一调度信息后,可以根据第一调度信息对用户终端发送的业务信息进行处理。
例如,业务信息的调制编码信息可以指示用户终端在发送业务信息时所采用的调制编码方式,以便基站在接收到业务信息后根据该调制编码信息对业务信息进行解调与解码。
又例如,业务信息的重复发送次数信息可以指示用户终端在发送业务信息失败后重新发送的次数,以便基站对多次接收到的业务信息进行混合反馈重传组合。
再例如,业务信息的发射功率控制信息可以指示用户终端在发送业务信息时所采用的发射功率,以便基站获知用户终端的发射功率,从而进行信道测量或信道估计等。
再例如,业务信息的签名信息可以指示用户终端在发送业务信息时所采用的交织方式,以便基站在接收到业务信息后根据该交织方式恢复交织前的信息(也可以将该操作称为“解交织”)。业务信息的签名信息还可以指示用户终端在发送业务信息时所采用的加扰方式,以便基站在接收到业务信息后根据该加扰方式恢复加扰前的信息(也可以将该操作称为“解扰”)。业务信息的签名信息还可以指示用户终端在发送业务信息时所采用的扩展方式,以便基站在接收到业务信息后根据该扩展方式恢复扩展前的信息。当然,业务信息的签名信息并不局限于此处列举的交织方式、加扰方式和扩展方式,还可以指示用户终端在发送业务信息时对业务信息进行的其他操作。
再例如,业务信息的参考信号信息可以指示用户终端在发送业务信息时所采用的信道的参考信号,以便基站进行信道测量或信道估计等。
再例如,业务信息的无线资源信息可以指示用户终端在发送业务信息时所占用的无线资源,以便基站在该无线资源上接收业务信息。
然后,在步骤S102中,接收基站对接入信息的响应信息,其中,响应信息包括基站对接入信息的确收信息。在本实施例中,当基站对接入信息进行正确解码时,基站可以向用户终端返回确收信息(也可以称为“ACK”)。另一方面,当基站没有对接入信息进行正确解码时,基站可以不向用户终端返回任何信息,或者可以向用户终端返回非确收信息(也可以称为“NACK”)。
根据本实施例的一个示例,当用户终端在步骤S101中发送的接入信息包括前导码时,用户终端在步骤S102中接收基站对前导码的响应信息,该响应信息包括基站对前导码的确收信息。例如,用户终端在步骤S101中发送前导码时,基站接收前导码并对其解码,若进行了正确的解码,基站可以向用户终端返回确收信息,则用户终端在步骤S102中接收基站对前导码的确收信息。在该示例中,正确的解码可以为基站通过解码获取了用户终端的标识信息,从而识别了用户终端的身份。
根据本实施例的另一示例,当用户终端在步骤S101中发送的接入信息包括上行数据控制信息时,用户终端在步骤S102中接收基站对上行数据控制信息的响应信息,该响应信息包括基站对上行数据控制信息的确收信息。例如,用户终端在步骤S101中发送上行数据控制信息时,基站接收上行数据控制信息并对其解码,若进行了正确的解码,基站可以向用户终端返回确收信息,则用户终端在步骤S102中接收基站对上行数据控制信息的确收信息。
根据本实施例的另一示例,当用户终端在步骤S101中的接入信息包括前导码和上行数据控制信息时,用户终端在步骤S102中接收基站对前导码和上行数据控制信息的响应信息,该响应信息包括基站对前导码和上行数据控制信息的确收信息。例如,用户终端在步骤S101中发送前导码和上行数据控制信息时,基站接收前导码和上行数据控制信息并对其解码,若进行了正确的解码,基站可以向用户终端返回确收信息,则用户终端在步骤S102中接收基站对前导码和上行数据控制信息的确收信息。
在该示例中,基站分别对前导码和上行数据控制信息进行了正确 解码后,才会向用户终端返回确收信息。
另外,根据本实施例的另一示例,用户终端在步骤S102中接收的响应信息还可以包括基站向用户终端发送的定时提前(Timing Advance,TA)信息。例如,基站可以向用户终端发送定时提前命令,告知用户终端定时提前的时间大小,从而避免基站和用户终端之间的距离引起的传输时延,并且减少该用户终端与其他用户终端之间的干扰。
此外,根据本实施例的另一示例,当用户终端在步骤S101中发送业务信息的第一调度信息时,基站接收业务信息的第一调度信息。然后,基站根据业务信息的第一调度信息生成修正的调度信息,并将修正的调度信息包括在响应信息中返回给用户终端。相应地,用户终端在步骤S102中接收修正的调度信息。
例如,当用户终端在步骤S101中发送业务信息的调度信息时,基站接收业务信息的调度信息。然后,基站可以基于小区内的负载状况、信道状况等灵活地修正所接收到的调度信息,以获得修正的调度信息。然后,基站可以将修正的调度信息包括在响应信息中返回给用户终端。相应地,用户终端在步骤S102中接收修正的调度信息。然后,用户终端在稍后的步骤S103中基于修正的调度信息向基站发送业务信息。
比如,用户终端在步骤S101中发送的调度信息可以包括业务信息的调制编码信息,当用户终端在步骤S101中发送业务信息的调制编码信息时,基站接收业务信息的调制编码信息。然后,基站可以基于小区内的负载状况、信道状况等为用户终端选择更优的编码调制方式,以获得更优的调制编码方式的信息。然后,基站可以将更优的调制编码方式的信息包括在响应信息中返回给用户终端。相应地,用户终端在步骤S102中接收更优的调制编码方式的信息。然后,用户终端在稍后的步骤S103中基于更优的调制编码方式向基站发送业务信息。
类似地,用户终端在步骤S101中发送的调度信息可以包括业务信息的重复发送次数信息、业务信息的发射功率控制信息、业务信息 的签名信息、业务信息的参考信号信息或业务信息的无线资源信息等。也就是说,基站可以基于小区内的负载状况、信道状况等为用户终端选择更优的重复发送次数、发射功率、签名方式、无线资源等。
当然,基站也可以基于小区内的负载状况、信道状况等为用户终端选择较差的调制编码方式、重复发送次数、发射功率、签名方式、无线资源等,牺牲了该用户终端的部分性能,而获得小区的整体性能提升。
根据本实施例的另一示例,基站还可以向用户终端发送第二调度信息。例如,当用户终端在步骤S101中发送业务信息的第一调度信息时,用户终端在步骤S102中接收的响应信息还可以包括第二调度信息。具体地,第二调度信息可以是基站对第一调度信息的补充信息。
例如,当用户终端在步骤S101中只发送了业务信息的调度信息中的调制编码信息时,用户终端在步骤S102中接收的响应信息可以包括业务信息的调度信息中的其他信息,比如重复发送次数信息、业务信息的发射功率控制信息、业务信息的签名信息、业务信息的参考信号信息或业务信息的无线资源信息等。
根据本实施例的另一示例,当用户终端在步骤S101中发送业务信息的第一调度信息时,用户终端在步骤S102中接收的响应信息不仅可以包括修正的第一调度信息,还可以包括第二调度信息。
例如,当用户终端在步骤S101中只发送了业务信息的调度信息中的调制编码信息时,基站在接收到调制编码信息后对其进行修正得到修正的调制编码信息,则用户终端在步骤S102中接收的响应信息不仅可以包括业务信息的调度信息中的其他信息,比如重复发送次数信息、业务信息的发射功率控制信息、业务信息的签名信息、业务信息的参考信号信息或业务信息的无线资源信息等,还可以包括修正的调制编码信息。
上面已经描述了用户终端在步骤S102中接收的响应信息的具体内容,下面描述用户终端在步骤S102中接收响应信息的时间。在本实施例中,用户终端在步骤S102中接收响应信息的时间可以是时刻或者时间窗口。
根据本实施例的一个示例,用户终端在步骤S101中发送用户终端的接入信息时,可以向基站发送指示第一时间间隔的信息。基站可以根据接收到的接入信息,经过第一时间间隔后发送对接入信息的响应信息。例如,基站在接收到接入信息后,可以在经过预定时间间隔后的时刻或时间窗口中的任意时刻发送基站对接入信息的响应信息。相应地,用户终端在步骤S101后可以在经过第一时间间隔的时刻或时间窗口中接收基站对接入信息的响应信息。
根据本实施例的另一示例,用户终端还可以确定周期性的信息接收窗口,并在步骤S101中发送用户终端的接入信息后的第一个信息接收窗口内接收基站对接入信息的响应信息。信息接收窗口可以是用户终端和基站之间传输信令的时间窗口。可替换地,信息接收窗口也可以是时间段。
在该示例中,在时间窗口中传输的信令可以包括基站向用户终端发送的用户终端专属信令信息,或者用户终端所属的用户终端组的组专属信令信息。用户终端专属信令可以包括小区参考信号、下行控制信息等;组专属信令信息可以包括信道质量状况、资源分配状况、用户终端分组状况等。
这里所提到的用户终端组可以包括在同一个时隙中传输信令信息的一个或多个用户终端,也可以包括在同一个频带内传输信令信息的一个或多个用户终端,也可以为在相邻的两个信息接收窗口之间的时间段内发送接入信息的一个或多个用户终端。
此外,根据本实施例的另一示例,基站可以在现有的下行信道上发送对接入信息的响应信息,也可以在专属信道上发送对接入信息的响应信息。
具体地,基站可以在下行链路控制信道、下行链路数据信道或响应信息传输信道上发送对接入信息的响应信息。相应地,用户终端在步骤S102中在对应的下行链路控制信道、下行链路数据信道或响应信息传输信道上接收基站对接入信息的响应信息。
例如,下行链路控制信道可以包括物理下行链路控制信道(Physical Downlink ControlChannel,PDCCH)、物理多播信道 (Physical Multicast CHannel,PMCH)、物理下行控制信道(Physical Downlink Control CHannel,PDCCH)、物理广播信道(Physical Broadcast CHannel,PBCH)、物理控制格式指示信道(Physical Control FormatIndicator Channel,PCFICH)、物理HARQ指示信道(Physical HARQ Indicator Channel,PHICH)等;下行链路数据信道可以包括物理下行共享信道(Physical Downlink Shared CHannel,PDSCH)等;响应信息传输信道可以包括专用于接收响应信息的信道。
根据本实施例的另一示例,用户终端在步骤S102中可以基于用户终端的标识信息和用于传输上行数据控制信息的无线资源的信息中的至少一个确定承载响应信息的无线资源,然后在无线资源上接收基站对接入信息的响应信息。
例如,基站为小区内的用户终端确定了传输响应信息的无线资源池,在接收到某个用户终端的接入信息后,为该用户终端选择一个无线资源,然后在该无线资源上传输对该用户终端的接入信息的响应信息。用户终端在步骤S102中可以基于用户终端的标识信息推算基站所使用的无线资源的索引序号,然后在与该索引序号相对应的无线资源上接收响应信息。
又例如,基站为小区内的用户终端确定了传输响应信息的无线资源池,在接收到该用户终端的接入信息后,为该用户终端选择一个无线资源,然后在该无线资源上传输对该用户终端的接入信息的响应信息。用户终端在步骤S102中可以不只是基于用户终端的标识信息,还可以基于用于传输上行数据控制信息的无线资源的信息推算基站所使用的无线资源的索引序号,然后在与该索引序号相对应的无线资源上接收响应信息。
在该示例中,基站可以将传输上行数据控制信息的频率资源作为传输响应信息的频率资源,即传输上行数据控制信息的频率资源与传输响应信息的频率资源可以是相同的。可替换地,基站还可以将传输上行数据控制信息的无线资源对应的子帧样式作为传输响应信息的子帧样式,即传输上行数据控制信息的子帧样式与传输响应信息的子帧样式可以是相同的。
然后,在步骤S103中,在接收到接入信息的响应信息后,发送业务信息,其中,业务信息包括数据信息。在本实施例中,用户终端只有在接收到基站对接入信息的响应信息后,才会发送业务信息,从而避免了无线资源的浪费。
根据本实施例的一个示例,当用户终端在步骤S101中发送的接入信息包括前导码、然后在步骤S102中接收基站对前导码的响应信息时,用户终端可以在步骤S103中发送数据信息。
根据本实施例的另一示例,当用户终端在步骤S101中发送的接入信息包括上行数据控制信息、然后在步骤S102中接收基站对上行数据控制信息的响应信息时,用户终端可以在步骤S103中发送数据信息。
根据本实施例的另一示例,当用户终端在步骤S101中发送的接入信息包括前导码和上行数据控制信息、然后在步骤S102中接收基站对前导码和上行数据控制信息的响应信息时,用户终端可以在步骤S103中发送数据信息。
根据本实施例的另一示例,当用户终端在步骤S101中发送的接入信息包括前导码、然后在步骤S102中接收基站对前导码的响应信息时,用户终端还可以在步骤S103中发送上行数据控制信息和数据信息。
根据本实施例的另一示例,当用户终端在步骤S101中发送的接入信息包括前导码、然后在步骤S102中接收基站对前导码的响应信息时,用户终端还可以在步骤S103中先发送上行数据控制信息,接收基站对上行数据控制信息的响应信息,该响应信息包括基站对上行数据控制信息的确收信息,然后在接收到上行数据控制信息的响应信息后,发送业务信息。
上面已经描述了用户终端在步骤S103中发送业务信息的具体过程,下面描述用户终端在步骤S103中发送业务信息的时间。
根据本实施例的一个示例,用户终端在步骤S101中发送用户终端的接入信息时,还可以向基站发送指示第二时间间隔的信息。用户终端在接收到响应信息后可以经过第二时间间隔向基站发送业务信 息,从而基站在相应的时刻接收用户终端发送的业务信息。例如,用户终端在接收到响应信息后,可以在经过预定时间间隔后的时刻或时间窗口中的任意时刻发送业务信息。
根据本实施例的另一示例,用户终端也可以不向基站发送指示第二时间间隔的信息。具体地,用户终端在接收到响应信息后,可以经过第三时间间隔后发送业务信息。
对于上面所提到的“第一时间间隔”、“第二时间间隔”和“第三时间间隔”,三者所对应的时间长度可以是相同的,也可以是不同的,本实施例不对此进行限定。
上面已经对步骤S101~103进行了详细的描述,下面将结合图2~图6进一步描述方法100的示例。

根据本发明实施例提供的由用户终端执行的用于免授权的上行链路的信息传输方法,用户终端首先向基站发送接入信息,在用户终端接收到基站对接入信息的确收信息后,用户终端再发送业务信息,避免了业务信息的无效传输,从而减少了无线资源的浪费,并且提高了上行频谱效率。
以下,参照图7描述根据本发明一个实施例的由基站执行的用于免授权的上行链路的信息传输方法。图7示出了用于免授权的上行链路的信息传输方法700的流程图。
如图7所示,在步骤S701中,接收用户终端的接入信息。根据本实施例的一个示例,接入信息可以包括前导(preamble)码(也可以称为前导序列或随机接入前导码)和/或上行数据控制信息。
例如,前导码可以包含长度为Tcp的循环前缀CP和长度为Tseq的序列。对于一个基站形成的小区,可以有64个前导码。用户终端在接入基站时从64个前导码中选择一个进行接入,以防止与其他用户终端的接入碰撞。
此外,前导码还可以包含用户终端的标识信息。用户终端的标识信息比如用户终端的ID、用户终端的物理地址(也可以称为Media Access Control(MAC)地址)或其它可以唯一标识用户终端的信息等,以标识用户终端的身份。基站在接收到用户终端的前导码后,可以从前导码中获取用户终端的标识信息,从而识别用户终端的身份。
又例如,上行数据控制信息可以包含用户终端的上行链路控制信道(Uplink Control CHannel,UL CCH)信息。
如上所述,在步骤S701中接收的接入信息可以包括前导码和上行数据控制信息二者。可替换地,在步骤S701中接收的接入信息还可以仅包括前导码和上行数据控制信息中的任意一个。
当接入信息包括前导码和上行数据控制信息时,前导码和上行数据控制信息可以都包含用户终端的标识信息,也可以二者中的一个包含用户终端的标识信息,以标识用户终端的身份。
此外,当接入信息仅包括上行数据控制信息时,上行数据控制信息还可以包含用户终端的标识信息。如上所述,用户终端的标识信息例如用户终端的ID、用户终端的MAC地址或其它可以唯一标识用户终端的信息等,以标识用户终端的身份。基站在接收到用户终端的上行数据控制信息后,可以从上行数据控制信息中获取用户终端的标识信息,从而识别用户终端的身份。
根据本实施例的另一示例,步骤S701中的接入信息还可以包括业务信息的第一调度信息。业务信息在稍后的步骤S703中进一步进行说明。
根据本实施例的一个示例,第一调度信息可以包括业务信息的调制编码信息、业务信息的重复发送次数信息、业务信息的发射功率控制信息、业务信息的签名信息、业务信息的参考信号信息和业务信息的无线资源信息中的至少一个。基站在接收到第一调度信息后,可以根据第一调度信息对用户终端发送的业务信息进行处理。
例如,业务信息的调制编码信息可以指示用户终端在发送业务信息时所采用的调制编码方式,以便基站在接收到业务信息后根据该调制编码信息对业务信息进行解调与解码。
又例如,业务信息的重复发送次数信息可以指示用户终端在发送业务信息失败后重新发送的次数,以便基站对多次接收到的业务信息进行混合反馈重传组合。
再例如,业务信息的发射功率控制信息可以指示用户终端在发送业务信息时所采用的发射功率,以便基站获知用户终端的发射功率,从而进行信道测量或信道估计等。
再例如,业务信息的签名信息可以指示用户终端在发送业务信息时所采用的交织方式,以便基站在接收到业务信息后根据该交织方式恢复交织前的信息(也可以将该操作称为“解交织”)。业务信息的签名信息还可以指示用户终端在发送业务信息时所采用的加扰方式,以便基站在接收到业务信息后根据该加扰方式恢复加扰前的信息(也可以将该操作称为“解扰”)。业务信息的签名信息还可以指示用户终端在发送业务信息时所采用的扩展方式,以便基站在接收到业务信息后根据该扩展方式恢复扩展前的信息。当然,业务信息的签名信息并不局限于此处列举的交织方式、加扰方式和扩展方式,还可以指示用户终端在发送业务信息时对业务信息进行的其他操作。
再例如,业务信息的参考信号信息可以指示用户终端在发送业务信息时所采用的信道的参考信号,以便基站进行信道测量或信道估计等。
再例如,业务信息的无线资源信息可以指示用户终端在发送业务信息时所占用的无线资源,以便基站在该无线资源上接收业务信息。
然后,在步骤S702中,对用户终端的接入信息进行解码,若正确解码,则发送响应信息,其中,响应信息包括基站对接入信息的确收信息。在本实施例中,当基站对接入信息进行正确解码时,基站可以向用户终端返回确收信息(也可以称为“ACK”)。另一方面,当基站没有对接入信息进行正确解码时,基站可以不向用户终端返回任何信息,或者可以向用户终端返回非确收信息(也可以称为“NACK”)。
根据本实施例的一个示例,当基站在步骤S701中接收的接入信息包括前导码时,基站在步骤S702中对用户终端的前导码进行解码,若正确解码,则发送响应信息,该响应信息包括基站对前导码的确收 信息。例如,基站在步骤S701中接收前导码时,基站在步骤S702中对其解码,若进行了正确的解码,可以向用户终端返回确收信息。在该示例中,正确的解码可以为基站通过解码获取了用户终端的标识信息,从而识别了用户终端的身份。
根据本实施例的另一示例,当基站在步骤S701中接收的接入信息包括上行数据控制信息时,基站在步骤S702中对用户终端的上行数据控制信息进行解码,若正确解码,则发送响应信息,该响应信息包括基站对上行数据控制信息的确收信息。例如,基站在步骤S701中接收上行数据控制信息时,基站在步骤S702中对其解码,若进行了正确的解码,可以向用户终端返回确收信息。
根据本实施例的另一示例,当基站在步骤S701中接收的接入信息包括前导码和上行数据控制信息时,基站在步骤S702中对用户终端的前导码和上行数据控制信息进行解码,若正确解码,则发送响应信息,该响应信息包括基站对前导码和上行数据控制信息的确收信息。例如,基站在步骤S701中接收前导码和上行数据控制信息时,基站在步骤S702中对其解码,若进行了正确的解码,可以向用户终端返回确收信息。
在该示例中,基站在步骤S702中分别对前导码和上行数据控制信息进行了正确解码后,才会向用户终端返回确收信息。
另外,根据本实施例的另一示例,基站在步骤S702中发送的响应信息还可以包括基站向用户终端发送的定时提前(Timing Advance,TA)信息。例如,基站可以向用户终端发送定时提前命令,告知用户终端定时提前的时间大小,从而避免基站和用户终端之间的距离引起的传输时延,并且减少该用户终端与其他用户终端之间的干扰。
此外,根据本实施例的另一示例,当基站在步骤S701中接收业务信息的第一调度信息时,基站根据业务信息的第一调度信息生成修正的调度信息,并在步骤S702中将修正的调度信息包括在响应信息中返回给用户终端。
例如,当用户终端发送业务信息的调度信息时,基站接收业务信息的调度信息。然后,基站可以基于小区内的负载状况、信道状况等 灵活地修正所接收到的调度信息,以获得修正的调度信息。然后,基站可以将修正的调度信息包括在响应信息中返回给用户终端。相应地,用户终端接收到修正的调度信息。然后,用户终端可以基于修正的调度信息向基站发送业务信息。
比如,基站在步骤S701中接收的调度信息可以包括业务信息的调制编码信息,然后基站可以基于小区内的负载状况、信道状况等为用户终端选择更优的编码调制方式,以获得更优的调制编码方式的信息。然后,基站可以在步骤S702中将更优的调制编码方式的信息包括在响应信息中返回给用户终端。然后,用户终端接收到更优的调制编码方式的信息后,可以基于更优的调制编码方式向基站发送业务信息。
类似地,基站在步骤S701中接收的调度信息可以包括业务信息的重复发送次数信息、业务信息的发射功率控制信息、业务信息的签名信息、业务信息的参考信号信息或业务信息的无线资源信息等。也就是说,基站可以基于小区内的负载状况、信道状况等为用户终端选择更优的重复发送次数、发射功率、签名方式、无线资源等。
当然,基站也可以基于小区内的负载状况、信道状况等为用户终端选择较差的调制编码方式、重复发送次数、发射功率、签名方式、无线资源等,牺牲了该用户终端的部分性能,而获得小区的整体性能提升。
根据本实施例的另一示例,基站在步骤S702中还可以向用户终端发送第二调度信息。例如,当基站在步骤S701中接收业务信息的第一调度信息时,基站可以生成第二调度信息,并且在步骤S702中发送的响应信息还可以包括第二调度信息。具体地,第二调度信息可以是基站对第一调度信息的补充信息。
例如,当基站在步骤S701中只接收了业务信息的调度信息中的调制编码信息时,基站在步骤S702中发送的响应信息可以包括业务信息的调度信息中的其他信息,比如重复发送次数信息、业务信息的发射功率控制信息、业务信息的签名信息、业务信息的参考信号信息或业务信息的无线资源信息等。
根据本实施例的另一示例,当基站在步骤S701中接收业务信息的第一调度信息时,基站在步骤S702中发送的响应信息不仅可以包括修正的第一调度信息,还可以包括第二调度信息。
例如,当基站在步骤S701中只接收了业务信息的调度信息中的调制编码信息时,基站在接收到调制编码信息后对其进行修正得到修正的调制编码信息,则基站在步骤S702中发送的响应信息不仅可以包括业务信息的调度信息中的其他信息,比如重复发送次数信息、业务信息的发射功率控制信息、业务信息的签名信息、业务信息的参考信号信息或业务信息的无线资源信息等,还可以包括修正的调制编码信息。
上面已经描述了基站在步骤S702中发送的响应信息的具体内容,下面描述基站在步骤S702中发送响应信息的时间。在本实施例中,基站在步骤S702中发送响应信息的时间可以是时刻或者时间窗口。
根据本实施例的一个示例,基站在步骤S701中还可以接收指示第一时间间隔的信息。基站在接收到接入信息后,可以经过第一时间间隔后发送对接入信息的响应信息。例如,基站在接收到接入信息后,可以在经过预定时间间隔后的时刻或时间窗口中的任意时刻发送基站对接入信息的响应信息。相应地,用户终端可以在经过第一时间间隔的时刻或时间窗口中接收基站对接入信息的响应信息。
根据本实施例的另一示例,基站还可以确定周期性的信息接收窗口,并在步骤S701中接收用户终端的接入信息后的第一个信息接收窗口内发送基站对接入信息的响应信息。信息接收窗口可以是用户终端和基站之间传输信令的时间窗口。可替换地,信息接收窗口也可以是时间段。
在该示例中,在时间窗口中传输的信令可以包括基站向用户终端发送的用户终端专属信令信息,或者用户终端所属的用户终端组的组专属信令信息。用户终端专属信令可以包括小区参考信号、下行控制信息等;组专属信令信息可以包括信道质量状况、资源分配状况、用户终端分组状况等。
这里所提到的用户终端组可以包括在同一个时隙中传输信令信 息的一个或多个用户终端,也可以包括在同一个频带内传输信令信息的一个或多个用户终端,也可以为在相邻的两个信息接收窗口之间的时间段内发送接入信息的一个或多个用户终端。
此外,根据本实施例的另一示例,基站可以在现有的下行信道上发送对接入信息的响应信息,也可以在专属信道上发送对接入信息的响应信息。
具体地,在步骤S702中,基站可以在下行链路控制信道、下行链路数据信道或响应信息传输信道上发送对接入信息的响应信息。相应地,用户终端在对应的下行链路控制信道、下行链路数据信道或响应信息传输信道上接收基站对接入信息的响应信息。
例如,下行链路控制信道可以包括物理下行链路控制信道(Physical Downlink ControlChannel,PDCCH)、物理多播信道(Physical Multicast CHannel,PMCH)、物理下行控制信道(Physical Downlink Control CHannel,PDCCH)、物理广播信道(Physical Broadcast CHannel,PBCH)、物理控制格式指示信道(Physical Control FormatIndicator Channel,PCFICH)、物理HARQ指示信道(Physical HARQ Indicator Channel,PHICH)等;下行链路数据信道可以包括物理下行共享信道(Physical Downlink Shared CHannel,PDSCH)等;响应信息传输信道可以包括专用于接收响应信息的信道。
根据本实施例的另一示例,基站在步骤S702中可以基于用户终端的标识信息和用于传输上行数据控制信息的无线资源的信息中的至少一个确定承载响应信息的无线资源,然后在无线资源上发送基站对接入信息的响应信息。
例如,基站为小区内的用户终端确定了传输响应信息的无线资源池,在接收到该用户终端的接入信息后,为该用户终端选择一个无线资源,然后在该无线资源上传输对该用户终端的接入信息的响应信息。基站在步骤S702中可以基于用户终端的标识信息推算基站所使用的无线资源的索引序号,然后在与该索引序号相对应的无线资源上发送响应信息。
又例如,基站为小区内的用户终端确定了传输响应信息的无线资 源池,在接收到该用户终端的接入信息后,为该用户终端选择一个无线资源,然后在该无线资源上传输对该用户终端的接入信息的响应信息。基站在步骤S702中可以不只是基于用户终端的标识信息,还可以基于用于传输上行数据控制信息的无线资源的信息推算基站所使用的无线资源的索引序号,然后在与该索引序号相对应的无线资源上发送响应信息。
在该示例中,基站可以将传输上行数据控制信息的频率资源作为传输响应信息的频率资源,即传输上行数据控制信息的频率资源与传输响应信息的频率资源可以是相同的。可替换地,基站还可以将传输上行数据控制信息的无线资源对应的子帧样式作为传输响应信息的子帧样式,即传输上行数据控制信息的子帧样式与传输响应信息的子帧样式可以是相同的。
另外,根据本实施例的另一示例,基站在步骤S702中可以分别向每个用户终端发送响应信息,可替换地,也可以同时发送一组用户终端的响应信息。此处的“一组用户终端”可以是上面所描述的“用户终端组”。
然后,在步骤S703中,在发送响应信息后,接收业务信息,其中,业务信息包括数据信息。在本实施例中,用户终端只有在接收到基站对接入信息的响应信息后,才会发送业务信息,从而避免了无线资源的浪费。相应地,基站在发送响应信息后,才会接收到业务信息。
根据本实施例的一个示例,当基站在步骤S701中接收的接入信息包括前导码、然后在步骤S702中发送基站对前导码的响应信息时,基站可以在步骤S703中接收数据信息。
根据本实施例的另一示例,当基站在步骤S701中接收的接入信息包括上行数据控制信息、然后在步骤S702中发送基站对上行数据控制信息的响应信息时,基站可以在步骤S703中接收数据信息。
根据本实施例的另一示例,当基站在步骤S701中接收的接入信息包括前导码和上行数据控制信息、然后在步骤S702中发送基站对前导码和上行数据控制信息的响应信息时,基站可以在步骤S703中接收数据信息。
根据本实施例的另一示例,当基站在步骤S701中接收的接入信息包括前导码、然后在步骤S702中发送基站对前导码的响应信息时,基站还可以在步骤S703中接收上行数据控制信息和数据信息。
根据本实施例的另一示例,当基站在步骤S701中接收的接入信息包括前导码、然后在步骤S702中发送基站对前导码的响应信息时,基站还可以在步骤S703中先接收上行数据控制信息,发送对上行数据控制信息的响应信息,该响应信息包括基站对上行数据控制信息的确收信息,然后在发送上行数据控制信息的响应信息后,接收业务信息。
上面已经描述了基站在步骤S703中接收业务信息的具体过程,下面描述基站在步骤S703中接收业务信息的时间。
根据本实施例的一个示例,基站在步骤S701中接收用户终端的接入信息时还接收指示第二时间间隔的信息时。用户终端在接收到响应信息后可以经过第二时间间隔向基站发送业务信息,从而基站在相应的时刻接收用户终端发送的业务信息。例如,用户终端在接收到响应信息后,可以在经过预定时间间隔后的时刻或时间窗口中的任意时刻发送业务信息。
对于上面所提到的“第一时间间隔”和“第二时间间隔”,二者所对应的时间长度可以是相同的,也可以是不同的,本实施例不对此进行限定。
上面已经对步骤S701~703进行了详细的描述,在此也可以结合图2~图6进一步描述方法700的示例。在此不再赘述。
根据本发明实施例提供的由基站执行的用于免授权的上行链路的信息传输方法,用户终端首先向基站发送接入信息,在用户终端接收到基站对接入信息的确收信息后,用户终端再发送业务信息,避免了业务信息的无效传输,从而减少了无线资源的浪费,并且提高了上行频谱效率。

例如,前导码可以包含长度为Tcp的循环前缀CP和长度为Tseq的序列。对于一个基站形成的小区,可以有64个前导码。用户终端在接入基站时从64个前导码中选择一个进行接入,以防止与其他用户终端的接入碰撞。
此外,前导码还可以包含用户终端的标识信息。用户终端的标识信息比如用户终端的ID、用户终端的物理地址(也可以称为Media Access Control(MAC)地址)或其它可以唯一标识用户终端的信息等,以标识用户终端的身份。基站在接收到用户终端的前导码后,可以从前导码中获取用户终端的标识信息,从而识别用户终端的身份。
又例如,上行数据控制信息可以包含用户终端的上行链路控制信道(Uplink Control CHannel,UL CCH)信息。
如上所述,发送单元801发送的接入信息可以包括前导码和上行数据控制信息二者。可替换地,发送单元801发送的接入信息还可以仅包括前导码和上行数据控制信息中的任意一个。
当接入信息包括前导码和上行数据控制信息时,前导码和上行数据控制信息可以都包含用户终端的标识信息,也可以二者中的一个包含用户终端的标识信息,以标识用户终端的身份。
此外,当接入信息仅包括上行数据控制信息时,上行数据控制信 息还可以包含用户终端的标识信息。如上所述,用户终端的标识信息例如用户终端的ID、用户终端的MAC地址或其它可以唯一标识用户终端的信息等,以标识用户终端的身份。基站在接收到用户终端的上行数据控制信息后,可以从上行数据控制信息中获取用户终端的标识信息,从而识别用户终端的身份。

再例如,业务信息的参考信号信息可以指示用户终端在发送业务信息时所采用的信道的参考信号,以便基站进行信道测量或信道估计等。
再例如,业务信息的无线资源信息可以指示用户终端在发送业务信息时所占用的无线资源,以便基站在该无线资源上接收业务信息。
然后,接收单元802接收基站对接入信息的响应信息,其中,响应信息包括基站对接入信息的确收信息。在本实施例中,当基站对接入信息进行正确解码时,基站可以向用户终端返回确收信息(也可以称为“ACK”)。另一方面,当基站没有对接入信息进行正确解码时,基站可以不向用户终端返回任何信息,或者可以向用户终端返回非确收信息(也可以称为“NACK”)。
根据本实施例的一个示例,当发送单元801发送的接入信息包括前导码时,接收单元802接收基站对前导码的响应信息,该响应信息包括基站对前导码的确收信息。例如,发送单元801发送前导码时,基站接收前导码并对其解码,若进行了正确的解码,基站可以向用户终端返回确收信息,则接收单元802接收基站对前导码的确收信息。在该示例中,正确的解码可以为基站通过解码获取了用户终端的标识信息,从而识别了用户终端的身份。

在该示例中,基站分别对前导码和上行数据控制信息进行了正确解码后,才会向用户终端返回确收信息。
另外,根据本实施例的另一示例,接收单元802接收的响应信息还可以包括基站向用户终端发送的定时提前(Timing Advance,TA)信息。例如,基站可以向用户终端发送定时提前命令,告知用户终端定时提前的时间大小,从而避免基站和用户终端之间的距离引起的传输时延,并且减少该用户终端与其他用户终端之间的干扰。
此外,根据本实施例的另一示例,当发送单元801发送业务信息的第一调度信息时,基站接收业务信息的第一调度信息。然后,基站根据业务信息的第一调度信息生成修正的调度信息,并将修正的调度信息包括在响应信息中返回给用户终端。相应地,接收单元802接收修正的调度信息。
例如,当发送单元801发送业务信息的调度信息时,基站接收业务信息的调度信息。然后,基站可以基于小区内的负载状况、信道状况等灵活地修正所接收到的调度信息,以获得修正的调度信息。然后,基站可以将修正的调度信息包括在响应信息中返回给用户终端。相应地,接收单元802接收修正的调度信息。然后,发送单元801基于修正的调度信息向基站发送业务信息。
比如,发送单元801发送的调度信息可以包括业务信息的调制编码信息,当发送单元801发送业务信息的调制编码信息时,基站接收业务信息的调制编码信息。然后,基站可以基于小区内的负载状况、信道状况等为用户终端选择更优的编码调制方式,以获得更优的调制编码方式的信息。然后,基站可以将更优的调制编码方式的信息包括在响应信息中返回给用户终端。相应地,接收单元802接收更优的调制编码方式的信息。然后,发送单元801基于更优的调制编码方式向基站发送业务信息。
类似地,发送单元801发送的调度信息可以包括业务信息的重 复发送次数信息、业务信息的发射功率控制信息、业务信息的签名信息、业务信息的参考信号信息或业务信息的无线资源信息等。也就是说,基站可以基于小区内的负载状况、信道状况等为用户终端选择更优的重复发送次数、发射功率、签名方式、无线资源等。
当然,基站也可以基于小区内的负载状况、信道状况等为用户终端选择较差的调制编码方式、重复发送次数、发射功率、签名方式、无线资源等,牺牲了该用户终端的部分性能,而获得小区的整体性能提升。
根据本实施例的另一示例,基站还可以向用户终端发送第二调度信息。例如,当发送单元801发送业务信息的第一调度信息时,接收单元802接收的响应信息还可以包括第二调度信息。具体地,第二调度信息可以是基站对第一调度信息的补充信息。
例如,当发送单元801只发送了业务信息的调度信息中的调制编码信息时,接收单元802接收的响应信息可以包括业务信息的调度信息中的其他信息,比如重复发送次数信息、业务信息的发射功率控制信息、业务信息的签名信息、业务信息的参考信号信息或业务信息的无线资源信息等。
根据本实施例的另一示例,当发送单元801发送业务信息的第一调度信息时,接收单元802接收的响应信息不仅可以包括修正的第一调度信息,还可以包括第二调度信息。
例如,当发送单元801只发送了业务信息的调度信息中的调制编码信息时,基站在接收到调制编码信息后对其进行修正得到修正的调制编码信息,则接收单元802接收的响应信息不仅可以包括业务信息的调度信息中的其他信息,比如重复发送次数信息、业务信息的发射功率控制信息、业务信息的签名信息、业务信息的参考信号信息或业务信息的无线资源信息等,还可以包括修正的调制编码信息。
上面已经描述接收单元802接收的响应信息的具体内容,下面描述接收单元802接收响应信息的时间。在本实施例中,接收单元802接收响应信息的时间可以是时刻或者时间窗口。
根据本实施例的一个示例,发送单元801发送用户终端的接入 信息时,可以向基站发送指示第一时间间隔的信息。基站可以根据接收到的接入信息,经过第一时间间隔后发送对接入信息的响应信息。例如,基站在接收到接入信息后,可以在经过预定时间间隔后的时刻或时间窗口中的任意时刻发送基站对接入信息的响应信息。相应地,接收单元802可以在经过第一时间间隔的时刻或时间窗口中接收基站对接入信息的响应信息。
根据本实施例的另一示例,发送单元801还可以确定周期性的信息接收窗口,并发送用户终端的接入信息后的第一个信息接收窗口内接收基站对接入信息的响应信息。信息接收窗口可以是用户终端和基站之间传输信令的时间窗口。可替换地,信息接收窗口也可以是时间段。
在该示例中,在时间窗口中传输的信令可以包括基站向用户终端发送的用户终端专属信令信息,或者用户终端所属的用户终端组的组专属信令信息。用户终端专属信令可以包括小区参考信号、下行控制信息等;组专属信令信息可以包括信道质量状况、资源分配状况、用户终端分组状况等。
这里所提到的用户终端组可以包括在同一个时隙中传输信令信息的一个或多个用户终端,也可以包括在同一个频带内传输信令信息的一个或多个用户终端,也可以为在相邻的两个信息接收窗口之间的时间段内发送接入信息的一个或多个用户终端。
此外,根据本实施例的另一示例,基站可以在现有的下行信道上发送对接入信息的响应信息,也可以在专属信道上发送对接入信息的响应信息。
具体地,基站可以在下行链路控制信道、下行链路数据信道或响应信息传输信道上发送对接入信息的响应信息。相应地,接收单元802在对应的下行链路控制信道、下行链路数据信道或响应信息传输信道上接收基站对接入信息的响应信息。
例如,下行链路控制信道可以包括物理下行链路控制信道(Physical Downlink ControlChannel,PDCCH)、物理多播信道(Physical Multicast CHannel,PMCH)、物理下行控制信道(Physical  Downlink Control CHannel,PDCCH)、物理广播信道(Physical Broadcast CHannel,PBCH)、物理控制格式指示信道(Physical Control FormatIndicator Channel,PCFICH)、物理HARQ指示信道(Physical HARQ Indicator Channel,PHICH)等;下行链路数据信道可以包括物理下行共享信道(Physical Downlink Shared CHannel,PDSCH)等;响应信息传输信道可以包括专用于接收响应信息的信道。
根据本实施例的另一示例,接收单元802可以基于用户终端的标识信息和用于传输上行数据控制信息的无线资源的信息中的至少一个确定承载响应信息的无线资源,然后在无线资源上接收基站对接入信息的响应信息。
例如,基站为小区内的用户终端确定了传输响应信息的无线资源池,在接收到某个用户终端的接入信息后,为该用户终端选择一个无线资源,然后在该无线资源上传输对该用户终端的接入信息的响应信息。接收单元802可以基于用户终端的标识信息推算基站所使用的无线资源的索引序号,然后在与该索引序号相对应的无线资源上接收响应信息。
又例如,基站为小区内的用户终端确定了传输响应信息的无线资源池,在接收到该用户终端的接入信息后,为该用户终端选择一个无线资源,然后在该无线资源上传输对该用户终端的接入信息的响应信息。接收单元802可以不只是基于用户终端的标识信息,还可以基于用于传输上行数据控制信息的无线资源的信息推算基站所使用的无线资源的索引序号,然后在与该索引序号相对应的无线资源上接收响应信息。
在该示例中,基站可以将传输上行数据控制信息的频率资源作为传输响应信息的频率资源,即传输上行数据控制信息的频率资源与传输响应信息的频率资源可以是相同的。可替换地,基站还可以将传输上行数据控制信息的无线资源对应的子帧样式作为传输响应信息的子帧样式,即传输上行数据控制信息的子帧样式与传输响应信息的子帧样式可以是相同的。
然后,在接收单元802接收到接入信息的响应信息后,发送单元 801发送业务信息,其中,业务信息包括数据信息。在本实施例中,接收单元802只有在接收到基站对接入信息的响应信息后,发送单元801才会发送业务信息,从而避免了无线资源的浪费。
根据本实施例的一个示例,当发送单元801发送的接入信息包括前导码、然后接收单元802接收基站对前导码的响应信息时,发送单元801发送数据信息。
根据本实施例的另一示例,当发送单元801发送的接入信息包括上行数据控制信息、然后接收单元802接收基站对上行数据控制信息的响应信息时,发送单元801发送数据信息。
根据本实施例的另一示例,当发送单元801发送的接入信息包括前导码和上行数据控制信息、然后接收单元802接收基站对前导码和上行数据控制信息的响应信息时,发送单元801发送数据信息。
根据本实施例的另一示例,当发送单元801发送的接入信息包括前导码、然后接收单元802接收基站对前导码的响应信息时,发送单元801发送上行数据控制信息和数据信息。
根据本实施例的另一示例,当发送单元801发送的接入信息包括前导码、然后接收单元802接收基站对前导码的响应信息时,发送单元801先发送上行数据控制信息,接收基站对上行数据控制信息的响应信息,该响应信息包括基站对上行数据控制信息的确收信息,然后在接收到上行数据控制信息的响应信息后,发送业务信息。
上面已经描述了发送单元801发送业务信息的具体过程,下面描述发送单元801发送业务信息的时间。
根据本实施例的一个示例,发送单元801发送用户终端的接入信息时,还可以向基站发送指示第二时间间隔的信息。用户终端在接收到响应信息后可以经过第二时间间隔向基站发送业务信息,从而基站在相应的时刻接收用户终端发送的业务信息。例如,用户终端在接收到响应信息后,可以在经过预定时间间隔后的时刻或时间窗口中的任意时刻发送业务信息。
根据本实施例的另一示例,发送单元801也可以不向基站发送指示第二时间间隔的信息。具体地,用户终端在接收到响应信息后, 可以经过第三时间间隔后发送业务信息。
对于上面所提到的“第一时间间隔”、“第二时间间隔”和“第三时间间隔”,三者所对应的时间长度可以是相同的,也可以是不同的,本实施例不对此进行限定。
上面已经对用户终端800进行了详细的描述,在此也可以结合图2~图6进一步描述用户终端800的示例。在此不再赘述。
根据本发明实施例提供的用于免授权的上行链路的信息传输的用户终端,用户终端首先向基站发送接入信息,在用户终端接收到基站对接入信息的确收信息后,用户终端再发送业务信息,避免了业务信息的无效传输,从而减少了无线资源的浪费,并且提高了上行频谱效率。
以下,参照图9描述根据本发明实施例的执行图7所示的方法700的基站。图9示出了执行图7所示的方法700的基站900的结构示意图。
如图9所示,基站900包括接收单元901,被配置为接收用户终端的接入信息。基站900还包括解码单元902,被配置为对用户终端的接入信息进行解码。基站900还包括发送单元903,并且在解码单元902对用户终端的接入信息进行正确解码后,发送单元903被配置为发送响应信息,其中,响应信息包括基站对接入信息的确收信息。另外,在发送单元903发送响应信息后,接收单元901还被配置为接收业务信息,其中,业务信息包括数据信息。除了这三个单元以外,基站900还可以包括其他部件,然而,由于这些部件与本发明实施例的内容无关,因此在这里省略其图示和描述。此外,由于根据本发明实施例的基站900执行的下述操作的具体细节与在上文中参照图2-6描述的细节相同,因此在这里为了避免重复而省略对相同细节的重复描述。
根据本实施例的一个示例,接入信息可以包括前导(preamble)码(也可以称为前导序列或随机接入前导码)和/或上行数据控制信息。
例如,前导码可以包含长度为Tcp的循环前缀CP和长度为Tseq的序列。对于一个基站形成的小区,可以有64个前导码。用户终端 在接入基站时从64个前导码中选择一个进行接入,以防止与其他用户终端的接入碰撞。
此外,前导码还可以包含用户终端的标识信息。用户终端的标识信息比如用户终端的ID、用户终端的物理地址(也可以称为Media Access Control(MAC)地址)或其它可以唯一标识用户终端的信息等,以标识用户终端的身份。基站在接收到用户终端的前导码后,可以从前导码中获取用户终端的标识信息,从而识别用户终端的身份。
又例如,上行数据控制信息可以包含用户终端的上行链路控制信道(Uplink Control CHannel,UL CCH)信息。
如上所述,接收单元901接收的接入信息可以包括前导码和上行数据控制信息二者。可替换地,接收单元901接收的接入信息还可以仅包括前导码和上行数据控制信息中的任意一个。
当接入信息包括前导码和上行数据控制信息时,前导码和上行数据控制信息可以都包含用户终端的标识信息,也可以二者中的一个包含用户终端的标识信息,以标识用户终端的身份。
此外,当接入信息仅包括上行数据控制信息时,上行数据控制信息还可以包含用户终端的标识信息。如上所述,用户终端的标识信息例如用户终端的ID、用户终端的MAC地址或其它可以唯一标识用户终端的信息等,以标识用户终端的身份。基站在接收到用户终端的上行数据控制信息后,可以从上行数据控制信息中获取用户终端的标识信息,从而识别用户终端的身份。
根据本实施例的另一示例,接收单元901接收的接入信息还可以包括业务信息的第一调度信息。业务信息在稍后进一步进行说明。
根据本实施例的一个示例,第一调度信息可以包括业务信息的调制编码信息、业务信息的重复发送次数信息、业务信息的发射功率控制信息、业务信息的签名信息、业务信息的参考信号信息和业务信息的无线资源信息中的至少一个。基站在接收到第一调度信息后,可以根据第一调度信息对用户终端发送的业务信息进行处理。
例如,业务信息的调制编码信息可以指示用户终端在发送业务信息时所采用的调制编码方式,以便基站在接收到业务信息后根据该调 制编码信息对业务信息进行解调与解码。
又例如,业务信息的重复发送次数信息可以指示用户终端在发送业务信息失败后重新发送的次数,以便基站对多次接收到的业务信息进行混合反馈重传组合。
再例如,业务信息的发射功率控制信息可以指示用户终端在发送业务信息时所采用的发射功率,以便基站获知用户终端的发射功率,从而进行信道测量或信道估计等。
再例如,业务信息的签名信息可以指示用户终端在发送业务信息时所采用的交织方式,以便基站在接收到业务信息后根据该交织方式恢复交织前的信息(也可以将该操作称为“解交织”)。业务信息的签名信息还可以指示用户终端在发送业务信息时所采用的加扰方式,以便基站在接收到业务信息后根据该加扰方式恢复加扰前的信息(也可以将该操作称为“解扰”)。业务信息的签名信息还可以指示用户终端在发送业务信息时所采用的扩展方式,以便基站在接收到业务信息后根据该扩展方式恢复扩展前的信息。当然,业务信息的签名信息并不局限于此处列举的交织方式、加扰方式和扩展方式,还可以指示用户终端在发送业务信息时对业务信息进行的其他操作。
再例如,业务信息的参考信号信息可以指示用户终端在发送业务信息时所采用的信道的参考信号,以便基站进行信道测量或信道估计等。
再例如,业务信息的无线资源信息可以指示用户终端在发送业务信息时所占用的无线资源,以便基站在该无线资源上接收业务信息。
然后,解码单元902对用户终端的接入信息进行解码,若正确解码,则发送响应信息,其中,响应信息包括基站对接入信息的确收信息。在本实施例中,当基站对接入信息进行正确解码时,基站可以向用户终端返回确收信息(也可以称为“ACK”)。另一方面,当基站没有对接入信息进行正确解码时,基站可以不向用户终端返回任何信息,或者可以向用户终端返回非确收信息(也可以称为“NACK”)。
根据本实施例的一个示例,当接收单元901接收的接入信息包括前导码时,解码单元902对用户终端的前导码进行解码,若正确解 码,则发送单元903发送响应信息,该响应信息包括基站对前导码的确收信息。例如,接收单元901接收前导码时,解码单元902对其解码,若进行了正确的解码,可以向用户终端返回确收信息。在该示例中,正确的解码可以为基站通过解码获取了用户终端的标识信息,从而识别了用户终端的身份。
根据本实施例的另一示例,当接收单元901接收的接入信息包括上行数据控制信息时,解码单元902对用户终端的上行数据控制信息进行解码,若正确解码,则发送单元903发送响应信息,该响应信息包括基站对上行数据控制信息的确收信息。例如,接收单元901接收上行数据控制信息时,解码单元902对其解码,若进行了正确的解码,发送单元903可以向用户终端返回确收信息。
根据本实施例的另一示例,当接收单元901接收的接入信息包括前导码和上行数据控制信息时,解码单元902对用户终端的前导码和上行数据控制信息进行解码,若正确解码,则发送单元903发送响应信息,该响应信息包括基站对前导码和上行数据控制信息的确收信息。例如,接收单元901接收前导码和上行数据控制信息时,解码单元902对其解码,若进行了正确的解码,发送单元903可以向用户终端返回确收信息。
在该示例中,解码单元902分别对前导码和上行数据控制信息进行了正确解码后,才会向用户终端返回确收信息。
另外,根据本实施例的另一示例,发送单元903发送的响应信息还可以包括基站向用户终端发送的定时提前(Timing Advance,TA)信息。例如,基站可以向用户终端发送定时提前命令,告知用户终端定时提前的时间大小,从而避免基站和用户终端之间的距离引起的传输时延,并且减少该用户终端与其他用户终端之间的干扰。
此外,根据本实施例的另一示例,当接收单元901接收业务信息的第一调度信息时,基站根据业务信息的第一调度信息生成修正的调度信息,并发送单元903将修正的调度信息包括在响应信息中返回给用户终端。
例如,当用户终端发送业务信息的调度信息时,基站接收业务信 息的调度信息。然后,基站可以基于小区内的负载状况、信道状况等灵活地修正所接收到的调度信息,以获得修正的调度信息。然后,基站可以将修正的调度信息包括在响应信息中返回给用户终端。相应地,用户终端接收到修正的调度信息。然后,用户终端可以基于修正的调度信息向基站发送业务信息。
比如,接收单元901接收的调度信息可以包括业务信息的调制编码信息,然后基站可以基于小区内的负载状况、信道状况等为用户终端选择更优的编码调制方式,以获得更优的调制编码方式的信息。然后,发送单元903将更优的调制编码方式的信息包括在响应信息中返回给用户终端。然后,用户终端接收到更优的调制编码方式的信息后,可以基于更优的调制编码方式向基站发送业务信息。
类似地,接收单元901接收的调度信息可以包括业务信息的重复发送次数信息、业务信息的发射功率控制信息、业务信息的签名信息、业务信息的参考信号信息或业务信息的无线资源信息等。也就是说,基站可以基于小区内的负载状况、信道状况等为用户终端选择更优的重复发送次数、发射功率、签名方式、无线资源等。
当然,基站也可以基于小区内的负载状况、信道状况等为用户终端选择较差的调制编码方式、重复发送次数、发射功率、签名方式、无线资源等,牺牲了该用户终端的部分性能,而获得小区的整体性能提升。
根据本实施例的另一示例,发送单元903还可以向用户终端发送第二调度信息。例如,当接收单元901接收业务信息的第一调度信息时,基站可以生成第二调度信息,并且发送单元903发送的响应信息还可以包括第二调度信息。具体地,第二调度信息可以是基站对第一调度信息的补充信息。
例如,当接收单元901只接收了业务信息的调度信息中的调制编码信息时,发送单元903发送的响应信息可以包括业务信息的调度信息中的其他信息,比如重复发送次数信息、业务信息的发射功率控制信息、业务信息的签名信息、业务信息的参考信号信息或业务信息的无线资源信息等。
根据本实施例的另一示例,当接收单元901接收业务信息的第一调度信息时,发送单元903发送的响应信息不仅可以包括修正的第一调度信息,还可以包括第二调度信息。
例如,当接收单元901只接收了业务信息的调度信息中的调制编码信息时,基站在接收到调制编码信息后对其进行修正得到修正的调制编码信息,则发送单元903发送的响应信息不仅可以包括业务信息的调度信息中的其他信息,比如重复发送次数信息、业务信息的发射功率控制信息、业务信息的签名信息、业务信息的参考信号信息或业务信息的无线资源信息等,还可以包括修正的调制编码信息。

根据本实施例的另一示例,基站还可以确定周期性的信息接收窗口,并在接收单元901接收用户终端的接入信息后的第一个信息接收窗口内发送基站对接入信息的响应信息。信息接收窗口可以是用户终端和基站之间传输信令的时间窗口。可替换地,信息接收窗口也可以是时间段。
在该示例中,在时间窗口中传输的信令可以包括基站向用户终端发送的用户终端专属信令信息,或者用户终端所属的用户终端组的组专属信令信息。用户终端专属信令可以包括小区参考信号、下行控制信息等;组专属信令信息可以包括信道质量状况、资源分配状况、用户终端分组状况等。
这里所提到的用户终端组可以包括在同一个时隙中传输信令信息的一个或多个用户终端,也可以包括在同一个频带内传输信令信息 的一个或多个用户终端,也可以为在相邻的两个信息接收窗口之间的时间段内发送接入信息的一个或多个用户终端。

根据本实施例的另一示例,发送单元903可以基于用户终端的标识信息和用于传输上行数据控制信息的无线资源的信息中的至少一个确定承载响应信息的无线资源,然后在无线资源上发送基站对接入信息的响应信息。
例如,基站为小区内的用户终端确定了传输响应信息的无线资源池,在接收到该用户终端的接入信息后,为该用户终端选择一个无线资源,然后在该无线资源上传输对该用户终端的接入信息的响应信息。发送单元903可以基于用户终端的标识信息推算基站所使用的无线资源的索引序号,然后在与该索引序号相对应的无线资源上发送响应信息。
又例如,基站为小区内的用户终端确定了传输响应信息的无线资源池,在接收到该用户终端的接入信息后,为该用户终端选择一个无 线资源,然后在该无线资源上传输对该用户终端的接入信息的响应信息。发送单元903可以不只是基于用户终端的标识信息,还可以基于用于传输上行数据控制信息的无线资源的信息推算基站所使用的无线资源的索引序号,然后在与该索引序号相对应的无线资源上发送响应信息。
在该示例中,基站可以将传输上行数据控制信息的频率资源作为传输响应信息的频率资源,即传输上行数据控制信息的频率资源与传输响应信息的频率资源可以是相同的。可替换地,基站还可以将传输上行数据控制信息的无线资源对应的子帧样式作为传输响应信息的子帧样式,即传输上行数据控制信息的子帧样式与传输响应信息的子帧样式可以是相同的。
另外,根据本实施例的另一示例,发送单元903可以分别向每个用户终端发送响应信息,可替换地,也可以同时发送一组用户终端的响应信息。此处的“一组用户终端”可以是上面所描述的“用户终端组”。
然后,发送单元903在发送响应信息后,接收单元901接收业务信息,其中,业务信息包括数据信息。在本实施例中,用户终端只有在接收到基站对接入信息的响应信息后,才会发送业务信息,从而避免了无线资源的浪费。相应地,发送单元903在发送响应信息后,接收单元901才会接收到业务信息。

对于上面所提到的“第一时间间隔”和“第二时间间隔”,二者所对应的时间长度可以是相同的,也可以是不同的,本实施例不对此进行限定。
上面已经对基站900进行了详细的描述,在此也可以结合图2~图6进一步描述基站900的示例。在此不再赘述。
根据本发明实施例提供的用于免授权的上行链路的信息传输的基站,用户终端首先向基站发送接入信息,在用户终端接收到基站对接入信息的确收信息后,用户终端再发送业务信息,避免了业务信息的无效传输,从而减少了无线资源的浪费,并且提高了上行频谱效率。

通信装置1040是用于通过有线和/或无线网络进行计算机间的通信的硬件(发送接收设备),例如也称为网络设备、网络控制器、网卡、通信模块等。通信装置1040为了实现例如频分双工(FDD,Frequency Division Duplex)和/或时分双工(TDD,Time Division Duplex),可以包括高频开关、双工器、滤波器、频率合成器等。例如,上述的发送接收天线、放大单元、发送接收单元、传输路径接口等可以通过通信装置1040来实现。
输入装置1050是接受来自外部的输入的输入设备(例如,键盘、鼠标、麦克风、开关、按钮、传感器等)。输出装置1060是实施向外部的输出的输出设备(例如,显示器、扬声器、发光二极管(LED,Light Emitting Diode)灯等)。另外,输入装置1050和输出装置1060也可以为一体的结构(例如触控面板)。
此外,处理器1010、内存1020等各装置通过用于对信息进行通信的总线1070连接。总线1070可以由单一的总线构成,也可以由装置间不同的总线构成。
此外,用户设备1000可以包括微处理器、数字信号处理器(DSP,Digital Signal Processor)、专用集成电路(ASIC,Application Specific Integrated Circuit)、可编程逻辑器件(PLD,Programmable Logic  Device)、现场可编程门阵列(FPGA,Field Programmable Gate Array)等硬件,可以通过该硬件来实现各功能块的部分或全部。例如,处理器1010可以通过这些硬件中的至少一个来安装。
关于本说明书中说明的用语和/或对本说明书进行理解所需的用语,可以与具有相同或类似含义的用语进行互换。例如,信道和/或符号也可以为信号(信令)。此外,信号也可以为消息。参考信号也可以简称为RS(Reference Signal),根据所适用的标准,也可以称为导频(Pilot)、导频信号等。此外,分量载波(CC,Component Carrier)也可以称为小区、频率载波、载波频率等。
此外,无线帧在时域中可以由一个或多个期间(帧)构成。构成无线帧的该一个或多个期间(帧)中的每一个也可以称为子帧。进而,子帧在时域中可以由一个或多个时隙构成。子帧可以是不依赖于参数配置(numerology)的固定的时间长度(例如1ms)。
进而,时隙在时域中可以由一个或多个符号(正交频分复用(OFDM,Orthogonal Frequency Division Multiplexing)符号、单载波频分多址(SC-FDMA,Single Carrier Frequency Division Multiple Access)符号等)构成。此外,时隙也可以是基于参数配置的时间单元。此外,时隙还可以包括多个微时隙。各微时隙在时域中可以由一个或多个符号构成。此外,微时隙也可以称为子时隙。
无线帧、子帧、时隙、微时隙以及符号均表示传输信号时的时间单元。无线帧、子帧、时隙、微时隙以及符号也可以使用各自对应的其它名称。例如,一个子帧可以被称为传输时间间隔(TTI,Transmission Time Interval),多个连续的子帧也可以被称为TTI,一个时隙或一个微时隙也可以被称为TTI。也就是说,子帧和/或TTI可以是现有的LTE中的子帧(1ms),也可以是短于1ms的期间(例如1~13个符号),还可以是长于1ms的期间。另外,表示TTI的单元也可以称为时隙、微时隙等而非子帧。
在此,TTI例如是指无线通信中调度的最小时间单元。例如,在LTE系统中,无线基站对各用户终端进行以TTI为单位分配无线资源(在各用户终端中能够使用的频带宽度、发射功率等)的调度。另外, TTI的定义不限于此。
TTI可以是经过信道编码的数据包(传输块)、码块、和/或码字的发送时间单元,也可以是调度、链路适配等的处理单元。另外,在给出TTI时,实际上与传输块、码块、和/或码字映射的时间区间(例如符号数)也可以短于该TTI。
另外,一个时隙或一个微时隙被称为TTI时,一个以上的TTI(即一个以上的时隙或一个以上的微时隙)也可以成为调度的最小时间单元。此外,构成该调度的最小时间单元的时隙数(微时隙数)可以受到控制。
具有1ms时间长度的TTI也可以称为常规TTI(LTE Rel.8-12中的TTI)、标准TTI、长TTI、常规子帧、标准子帧、或长子帧等。短于常规TTI的TTI也可以称为压缩TTI、短TTI、部分TTI(partial或fractional TTI)、压缩子帧、短子帧、微时隙、或子时隙等。
另外,长TTI(例如常规TTI、子帧等)也可以用具有超过1ms的时间长度的TTI来替换,短TTI(例如压缩TTI等)也可以用具有比长TTI的TTI长度短且1ms以上的TTI长度的TTI来替换。
资源块(RB,Resource Block)是时域和频域的资源分配单元,在频域中,可以包括一个或多个连续的副载波(子载波(subcarrier))。此外,RB在时域中可以包括一个或多个符号,也可以为一个时隙、一个微时隙、一个子帧或一个TTI的长度。一个TTI、一个子帧可以分别由一个或多个资源块构成。另外,一个或多个RB也可以称为物理资源块(PRB,Physical RB)、子载波组(SCG,Sub-Carrier Group)、资源单元组(REG,Resource Element Group)、PRG对、RB对等。
此外,资源块也可以由一个或多个资源单元(RE,Resource Element)构成。例如,一个RE可以是一个子载波和一个符号的无线资源区域。
另外,上述的无线帧、子帧、时隙、微时隙以及符号等的结构仅仅为示例。例如,无线帧中包括的子帧数、每个子帧或无线帧的时隙数、时隙内包括的微时隙数、时隙或微时隙中包括的符号和RB的数目、RB中包括的子载波数、以及TTI内的符号数、符号长度、循环 前缀(CP,Cyclic Prefix)长度等的结构可以进行各种各样的变更。
此外,本说明书中说明的信息、参数等可以用绝对值来表示,也可以用与规定值的相对值来表示,还可以用对应的其它信息来表示。例如,无线资源可以通过规定的索引来指示。进一步地,使用这些参数的公式等也可以与本说明书中明确公开的不同。
在本说明书中用于参数等的名称在任何方面都并非限定性的。例如,各种各样的信道(PUCCH、PDCCH等)和信息单元可以通过任何适当的名称来识别,因此为这些各种各样的信道和信息单元所分配的各种各样的名称在任何方面都并非限定性的。
本说明书中说明的信息、信号等可以使用各种各样不同技术中的任意一种来表示。例如,在上述的全部说明中可能提及的数据、命令、指令、信息、信号、比特、符号、芯片等可以通过电压、电流、电磁波、磁场或磁性粒子、光场或光子、或者它们的任意组合来表示。
此外,信息、信号等可以从上层向下层、和/或从下层向上层输出。信息、信号等可以经由多个网络节点进行输入或输出。
输入或输出的信息、信号等可以保存在特定的场所(例如内存),也可以通过管理表进行管理。输入或输出的信息、信号等可以被覆盖、更新或补充。输出的信息、信号等可以被删除。输入的信息、信号等可以被发往其它装置。
信息的通知并不限于本说明书中说明的方式/实施方式,也可以通过其它方法进行。例如,信息的通知可以通过物理层信令(例如,下行链路控制信息(DCI,Downlink Control Information)、上行链路控制信息(UCI,Uplink Control Information))、上层信令(例如,无线资源控制(RRC,Radio Resource Control)信令、广播信息(主信息块(MIB,Master Information Block)、系统信息块(SIB,System Information Block)等)、媒体存取控制(MAC,Medium Access Control)信令)、其它信号或者它们的组合来实施。
另外,物理层信令也可以称为L1/L2(第1层/第2层)控制信息(L1/L2控制信号)、L1控制信息(L1控制信号)等。此外,RRC信令也可以称为RRC消息,例如可以为RRC连接建立(RRC Connection  Setup)消息、RRC连接重配置(RRC Connection Reconfiguration)消息等。此外,MAC信令例如可以通过MAC控制单元(MAC CE(Control Element))来通知。
此外,规定信息的通知(例如,“为X”的通知)并不限于显式地进行,也可以隐式地(例如,通过不进行该规定信息的通知,或者通过其它信息的通知)进行。
关于判定,可以通过由1比特表示的值(0或1)来进行,也可以通过由真(true)或假(false)表示的真假值(布尔值)来进行,还可以通过数值的比较(例如与规定值的比较)来进行。
软件无论被称为软件、固件、中间件、微代码、硬件描述语言,还是以其它名称来称呼,都应宽泛地解释为是指命令、命令集、代码、代码段、程序代码、程序、子程序、软件模块、应用程序、软件应用程序、软件包、例程、子例程、对象、可执行文件、执行线程、步骤、功能等。
此外,软件、命令、信息等可以经由传输介质被发送或接收。例如,当使用有线技术(同轴电缆、光缆、双绞线、数字用户线路(DSL,Digital Subscriber Line)等)和/或无线技术(红外线、微波等)从网站、服务器、或其它远程资源发送软件时,这些有线技术和/或无线技术包括在传输介质的定义内。

在本说明书中,“基站(BS,Base Station)”、“无线基站”、“eNB”、“gNB”、“小区”、“扇区”、“小区组”、“载波”以及“分量载波”这样的用语可以互换使用。基站有时也以固定台(fixed station)、NodeB、eNodeB(eNB)、接入点(access point)、发送点、接收点、毫微微小区、小小区等用语来称呼。
基站可以容纳一个或多个(例如三个)小区(也称为扇区)。当基站容纳多个小区时,基站的整个覆盖区域可以划分为多个更小的区域,每个更小的区域也可以通过基站子系统(例如,室内用小型基站(射频拉远头(RRH,Remote Radio Head)))来提供通信服务。“小区”或“扇区”这样的用语是指在该覆盖中进行通信服务的基站和/或基 站子系统的覆盖区域的一部分或整体。
在本说明书中,“移动台(MS,Mobile Station)”、“用户终端(user terminal)”、“用户装置(UE,User Equipment)”以及“终端”这样的用语可以互换使用。移动台有时也被本领域技术人员以用户台、移动单元、用户单元、无线单元、远程单元、移动设备、无线设备、无线通信设备、远程设备、移动用户台、接入终端、移动终端、无线终端、远程终端、手持机、用户代理、移动客户端、客户端或者若干其它适当的用语来称呼。
此外,本说明书中的无线基站也可以用用户终端来替换。例如,对于将无线基站和用户终端间的通信替换为多个用户终端间(D2D,Device-to-Device)的通信的结构,也可以应用本发明的各方式/实施方式。此时,可以将上述的无线基站所具有的功能当作用户终端所具有的功能。此外,“上行”和“下行”等文字也可以替换为“侧”。例如,上行信道也可以替换为侧信道。
同样,本说明书中的用户终端也可以用无线基站来替换。此时,可以将上述的用户终端所具有的功能当作无线基站所具有的功能。
在本说明书中,设为通过基站进行的特定动作根据情况有时也通过其上级节点(upper node)来进行。显然,在具有基站的由一个或多个网络节点(network nodes)构成的网络中,为了与终端间的通信而进行的各种各样的动作可以通过基站、除基站之外的一个以上的网络节点(可以考虑例如移动管理实体(MME,Mobility Management Entity)、服务网关(S-GW,Serving-Gateway)等,但不限于此)、或者它们的组合来进行。
本说明书中说明的各方式/实施方式可以单独使用,也可以组合使用,还可以在执行过程中进行切换来使用。此外,本说明书中说明的各方式/实施方式的处理步骤、序列、流程图等只要没有矛盾,就可以更换顺序。例如,关于本说明书中说明的方法,以示例性的顺序给出了各种各样的步骤单元,而并不限定于给出的特定顺序。

本说明书中使用的“根据”这样的记载,只要未在其它段落中明确记载,则并不意味着“仅根据”。换言之,“根据”这样的记载是指“仅根据”和“至少根据”这两者。
本说明书中使用的对使用“第一”、“第二”等名称的单元的任何参照,均非全面限定这些单元的数量或顺序。这些名称可以作为区别两个以上单元的便利方法而在本说明书中使用。因此,第一单元和第二单元的参照并不意味着仅可采用两个单元或者第一单元必须以若干形式占先于第二单元。
本说明书中使用的“判断(确定)(determining)”这样的用语有时包含多种多样的动作。例如,关于“判断(确定)”,可以将计算(calculating)、推算(computing)、处理(processing)、推导(deriving)、调查(investigating)、搜索(looking up)(例如表、数据库、或其它数据结构中的搜索)、确认(ascertaining)等视为是进行“判断(确定)”。此外,关于“判断(确定)”,也可以将接收(receiving)(例如接收信息)、发送(transmitting)(例如发送信息)、输入(input)、输出(output)、存取(accessing)(例如存取内存中的数据)等视为是进行“判断(确定)”。此外,关于“判断(确定)”,还可以将解决(resolving)、选择 (selecting)、选定(choosing)、建立(establishing)、比较(comparing)等视为是进行“判断(确定)”。也就是说,关于“判断(确定)”,可以将若干动作视为是进行“判断(确定)”。

在本说明书或权利要求书中使用“包括”、“包含”、以及它们的变形时,这些用语与用语“具备”同样是开放式的。进一步地,在本说明书或权利要求书中使用的用语“或(or)”并非是异或。
以上对本发明进行了详细说明,但对于本领域技术人员而言,显然,本发明并非限定于本说明书中说明的实施方式。本发明在不脱离由权利要求书的记载所确定的本发明的宗旨和范围的前提下,可以作为修改和变更方式来实施。因此,本说明书的记载是以示例说明为目的,对本发明而言并非具有任何限制性的意义。
