Description
本发明实施例涉及通信领域,尤其涉及一种数据传输的方法、装置和用户设备及***。
频谱是无线通信中非常昂贵的资源。对于现代通信***,例如全球移动通信***(Global System for Mobile Communication,GSM)***、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)***以及长期演进(Long Term Evolution,LTE)***,通常都工作在3吉赫(GHz)以下的载频上。随着智能终端特别是视频业务的出现,当前的频谱资源已经难以满足用户对容量需求的***式增长。具有更大的可用带宽的高频频段(特别是毫米波频段)日益成为下一代通信***的候选频段。例如在3GHz-200GHz的范围内,潜在的可用带宽约为250GHz。
现代通信***通常使用多天线技术来提高***的容量和覆盖或者改善用户的体验,使用高频频段带来的另一个好处就是可以大大减小多天线配置的尺寸,从而便于站址获取和更多天线的部署。然而,与现有LTE***的工作频段不同的是,高频频段将导致更大的路径损耗,特别是大气、植被等因素的影响更进一步加剧了无线传播的损耗。此时,现有LTE***中同步信道、控制信道以及广播消息等发送的可靠性将受到影响。为解决上述高频载波特别是毫米波场景条件下的覆盖问题,一种实现方法是将模拟域的多个天线阵子虚拟加权为一个天线端口后进行数据发射,因此每个端口的发射数据均可取得波束赋形(Beam Forming,BF)的阵列增益从而克服高频下的路径损耗。但同时阵列形成的发射信号的波束较窄,因此只能覆盖小区内的一部分用户,进一步通过时分的方式进行模拟域的BF和相应的数据发射来保证整个小区所有用户的覆盖。
在上述的模拟域的BF中,一个射频(Radio Frequency,RF)链对应一组多个天线阵子的虚拟加权(即一个模拟波束),不同的虚拟加权对应不同的RF链,当不同发射时刻采用不同的虚拟加权时即需要从一个模拟波束切换到另一
个模拟波束。从而在***帧结构设计中需要考虑上述模拟波束的切换时间段。现有技术中在正交频分多址复用(Orthogonal Frequency Division Multiplexing,OFDM)中存在一种设置模拟波束切换时间段的方式,在每个待发送的调制符号上用一段空循环前缀(Cyclic Prefix,CP)代替正常CP,将此空CP的时间段作为切换时间段,然后在此空CP的时间段内基站完成从一个模拟波束到另一个模拟波束的切换,所以不需要再预留额外的保护时间。但是,现有技术中对于无线帧中的每个调制符号都会设置切换时间段,况且对于待发送的调制符号上承载的数据而言,并不需要如此频繁的进行模拟波束的切换,设置过多的切换时间段这会极大的浪费资源。

公共信道和/或公共参考信号进行模拟波束的切换,然后根据第一时间单元的配置信息在第一时间单元的第一子时间单元传输公共信道和/或公共参考信号,则公共信道和/或公共参考信号在第一子时间单元内的传输时间段内传输。由于在无线时间窗中第一时间单元中每隔至少N个子时间单元后的第一子时间单元内预留了可进行模拟波束切换的切换时间段,故可以在该切换时间段内调整天线阵子的虚拟加权进行模拟波束的切换,公共信道和/或公共参考信道不在切换时间段内传输,而是在第一子时间单元中的传输时间段传输。由于预设切换时间段所属的第一子时间单元是第一时间单元中每隔至少N个子时间单元后的子时间单元,所以不需要在无线时间窗中每个时间单元的每个子时间单元都设置切换时间段,从而可以避免资源的浪费。

以下分别进行详细说明。
请参阅图1-a所示,本发明实施例提供的一种数据传输的装置100,可以包括:时间单元确定模块101、数据传输模块102,其中,
时间单元确定模块101,用于确定无线时间窗中第一时间单元的配置信息,其中,所述第一时间单元包括多个子时间单元,所述第一时间单元中每隔至少N个子时间单元后的第一子时间单元内预留切换时间段和传输时间段,所述切换时间段用于公共信道和/或公共参考信号进行模拟波束的切换,所述N为自然数;
数据传输模块102,用于根据所述第一时间单元的配置信息在所述第一时间单元的第一子时间单元传输所述公共信道和/或公共参考信号,其中,所述公共信道和/或公共参考信号在所述传输时间段内传输。

进一步的,所述第一子时间单元内的所述切换时间段通过替换公共信道和/或公共参考信号的循环前缀CP得到;或,

在本发明的一些实施例中,所述第一时间单元的配置信息,包括:所述第一时间单元的时间配比编号,所述时间配比编号是按照配比周期确定的所述公共信道和/或公共参考信号传输占用的第一时间单元的配置。
在本发明的一些实施例中,所述第二时间单元包含的子时间单元个数大于等于所述第一时间单元包含的子时间单元个数。
在本发明实施例中,使用高频频段传输数据存在较大的无线传播损耗,通过将模拟域的多个天线阵子虚拟加权为一个天线端口后进行数据发射,每个端口的发射数据均可取得波束赋形的阵列增益从而克服高频下较大的路径损耗。但同时阵列形成的发射信号的波束较窄,需要通过时分的方式进行模拟域的波束赋形和相应的数据发射来保证整个小区所有用户的覆盖。
在模拟域的波束赋形中,一个射频(Radio Frequency,RF)链对应一组多个天线阵子的虚拟加权(即对应一个模拟波束),不同的虚拟加权对应不同的模拟波束,当不同发射时刻采用不同的虚拟加权时即需要从一个模拟波束切换
到另一个模拟波束,所以在***帧结构设计中需要考虑怎样设置上述模拟波束的切换时间段。
现有技术中在OFDM中存在设置模拟波束切换时间段的方式,会在每个待发送的调制符号上用一段空循环前缀(Cyclic Prefix,CP)代替正常CP,将此空CP的时间段作为切换时间段,然后在此空CP的时间段内基站完成从一个模拟波束到另一个模拟波束的切换,所以不需要再预留额外的保护时间。但是,现有技术中对于无线帧中的每个调制符号中都需要设置切换时间段,况且对于待发送的调制符号上承载的数据而言,并不需要如此频繁的进行模拟波束的切换,设置过多的切换时间段会极大的浪费资源。
为了解决上述现有技术存在的问题,本发明实施例中时间单元确定模块101对传输的数据进行分类,并针对不同类别的数据采用与数据自身传输相适配的切换时间段设置方式,其中,无线时间窗指的是无线信号传输使用的时域资源,例如结合具体的应用场景,一个无线时间窗可以指的是一个广义的无线传输时间单位,也可以指的是一个具体的传输时间单位,如一个超帧,无线帧,或子帧,时隙等。在无线时间窗中传输的数据可以分为两类:一类是公共信道和/或公共参考信号,另一类是业务信道。据于划分的两类数据,将用于传输上述数据的每个无线时间窗中的所有时间单元划分为两类,一类定义为第一时间单元,另一类定义为第二时间单元,例如,无线时间窗为一个无线帧,则第一时间单元可以表示无线帧中的第一子帧,第二时间单元可以表示无线帧中的第二子帧。或所述无线时间窗为一个超帧,则第一时间单元表示无线超帧中的第一无线帧,第二时间单元表示无线超帧中的第二无线帧。或所述无线时间窗为一个无线子帧,则第一时间单元表示无线子帧中的第一符号,第二时间单元表示无线子帧中的第二符号。其中,公共信道和/或公共参考信号在无线时间窗中的第一时间单元进行传输,业务信道在无线时间窗中的第二时间单元进行传输,也就是说,第一时间单元为公共信道和/或公共参考信号传输的时间单元,第二时间单元为业务信道传输的时间单元。在一个无线时间窗中可以有一个第一时间单元,也可以有多个第一时间单元,同样的,在一个无线时间窗中可以有一个第二时间单元,也可以有多个第二时间单元。另外,本发明实施例中公共信道和/或公共参考信号可以包括同步信号、控制信道以及广播信道等,例如物理广播信道(Physical Broadcast Channel,PBCH)、物理混合重传请求
指示信道(Physical Hybrid Auto Repeat Request Indicator Channel,PHICH)、物理控制格式指示信道(Physical Control Format Indicator Channel,PCFICH)、主同步信号/辅同步信号(Primary Syncronization Signal/Secondary Syncronization Signal,PSS/SSS)、物理下行控制信道(Physical Downlink Control Channel、PDCCH)等。
由于高频下存在较大的路径损耗和大尺度衰落,业务信道的覆盖可通过发射端的很多个天线端口的波束赋形来克服,而公共信道和公共参考信号的传输,由于需保证整个小区的广覆盖通常不采用波束赋形技术,导致覆盖严重受限。为保证公共信道和或公共参考信号的小区级覆盖,通常可时分的进行多个模拟波束的发送。其中,每个模拟波束对应一套多个天线阵子上的虚拟加权。此外,在实际***中,业务信道的数据传输的时间粒度通常大于公共信道和或公共参考信号的数据或信号传输的时间粒度,如LTE***中,业务信道的数据传输的时间粒度是一个无线子帧,而公共信道和或公共参考信号的数据或信号传输的时间粒度是无线子帧中的一个或几个符号。因此业务信道的数据传输所基于的模拟波束的变换或切换的时间粒度和公共信道和或公共参考信号的数据或信号传输所对应的模拟波束的变换或切换的时间粒度设置不同。如业务信道的数据传输的模拟波束切换是子帧量级的,即业务信道传输所基于的模拟波束切换的最小时间粒度为子帧。而公共信道和或公共参考信号的数据或信号传输的模拟波束切换是符号量级的,即公共信道和或公共参考信号传输的模拟波束切换的最小时间粒度为符号。
具体的,对于公共信道和/或公共参考信号传输的第一时间单元而言,从第一时间单元中每隔N个子时间单元确定出一个第一子时间单元,例如N的取值为2时,那就是在第一时间单元中每隔2个子时间单元就会存在一个第一子时间单元。在第一子时间单元内预留出切换时间段和传输时间段,则第一子时间单元内的时间资源被分为两个时间段,两个时间段分别有各自的用途,明确的是,将切换时间段预留给模拟波束的切换使用。
进一步的,还可以首先确定公共信道和/或公共参考信号在第一时间单元中每次传输占用的第一时间单元中的子时间单元个数,例如,公共信道和/或公共参考信号在第一子帧中每次传输占用的第一子帧中的符号数。将该子时间单元个数用N来表示,N的取值为大于或等于1的自然数,根据公共信道和/
或公共参考信号占用的子时间单元个数N从无线时间窗的第一时间单元中每隔至少N个子时间单元后的第一子时间单元内确定出一个时间段,被确定出的时间段为切换时间段,由于确定出的时间段(即切换时间段)预留给模拟波束的切换使用,也就是说,本发明实施例中可以根据第一时间单元中传输的公共信道和/或公共参考信号占用的子时间单元个数来确定在第一子时间单元,从而确定所述第一子时间单元中预留的切换时间段,其中,对于公共信道和/或公共参考信号的具体实现,子时间单元个数N的取值也有相应的具体值,后续过程进行举例说明。需要说明的是,本发明实施例中,模拟波束的切换时间段可以是零点几个微秒或几微秒或几十微秒,因此不局限于一个第一子时间单元内,可选地,所述切换时间段可以是一个第一子时间单元内的一个时间段,也可以是一个或几个第一子时间单元。
在本发明实施例中,在无线时间窗的第一时间单元中的第一子时间单元的切换时间段进行所述公共信道和或公共参考信号对应的模拟波束的切换,具体的,在所述切换时间段内,公共信道和/或公共参考信号可以调整或切换多个天线阵子的虚拟加权。上述传输时间段指的是第一子时间单元内的传输时间段,例如在第一子时间单元内切换时间段之外的传输时间段内传输公共信道和/或公共参考信号。
在本发明的一些实施例中,在第一子时间单元内除切换时间段之外还存在传输时间段,则第一子时间单元由切换时间段和传输时间段组成,或者在第一子时间单元内除切换时间段之外还存在传输时间段和循环前缀时间段,则第一子时间单元由切换时间段,传输时间段和循环前缀时间段组成。对于第一子时间单元由切换时间段和传输时间段组成的情况下,第一子时间单元内的切换时间段可选地可通过替换传输时间段内传输的公共信道和/或公共参考信号的循环前缀(Cyclic Prefix,CP)得到。也就是说,在第一子时间单元内原来用作CP的时间段被预留作为切换时间段。对于第一子时间单元由切换时间段、传输时间段和循环前缀时间段组成的情况下,循环前缀时间段用于传输公共信道和/或公共参考信号的CP,也就是说,在第一子时间单元内,除了包括切换时间段和传输时间段外,还包括循环前缀时间段,并且循环前缀时间段用于公共信道和/或公共参考信号的CP,所以CP占用的时间段并没有被预留作为切换时间段。接下来以无线时间窗具体为无线帧的情况下进行举例说明,第一时间
单元具体为第一子帧,子时间单元具体为子帧中的符号,则第一子时间单元具体为第一子帧中的第一符号。在这种情况下,在第一子帧中每隔至少N个符号后的第一符号内保留正常CP,且在第一子帧中每隔至少N个符号后的第一符号内CP时间段外的时间段预留出切换时间段用于模拟波束的切换;或,将第一子帧中每隔至少N个符号后的第一符号内的正常CP替换为切换时间段,此时切换时间段用作模拟波束的切换。
在上述一种举例说明中,确定在第一子帧中每隔至少N个符号后的第一符号内预留切换时间段时,预留的切换时间段可以不占用正常CP,而是占用第一子帧中每隔至少N个符号后的第一符号内CP时间段外的时间段,如第一符号的尾部,这样可以保留无线子帧中的原有正常CP,在上述另一种举例说明中,确定在第一子帧中每隔至少N个符号后的第一符号内预留切换时间段时,预留的切换时间段可以占用正常CP,从而正常CP被替换为模拟波束的切换时间段,在OFDM***中各个子载波的正交性是通过正常CP来实现的,按照上述步骤的做法,正常CP被切换时间段代替,那么各个子载波间的正交性被破坏,因此相比于仍预留循环前缀时间段使用正常CP的OFDM***的帧结构设计,使用切换时间段替代正常CP的OFDM***的帧结构设计所对应的传输性能将大大下降。
需要说明的是,在本发明实施例中,在第一子帧中预留切换时间段的符号数可以是一个或者多个,例如在无线帧的第一子帧中每隔至少N个符号后的每个符号内都预留切换时间段用于模拟波束的切换。公共信道和/公共参考信号的传输基于第一子帧进行,所述第一子帧中每隔至少N个符号后的每个符号中预留切换时间段用于模拟波束的切换。公共信道和/或公共参考信号在第一子帧传输能保证公共信道和/或公共参考信号可基于每符号的粒度进行模拟波束的灵活切换。此外,第一子帧的每个符号的设计可以是保留正常CP,如基于当前LTE***中的OFDM符号的一种结构,即保留当前OFDM符号中的正常CP而在正常CP外的时间段如每符号的尾部预留出切换时间段用于模拟波束的切换,请参阅如图2-a所示,为本发明实施例中第一子帧的一种帧结构示意图,其中,第一子帧包括两个时隙(slot),以其中一个时隙的帧结构为例进行图示说明,1个时隙包括6个符号,每个符号用NCP-OFDM表示,在每个符号中保留正常CP,且在每个符号的尾部预留出模拟波束的切换时间段,图中
用黑色方块表示正常CP,用灰色方块表示公共信道和/或公共参考信号,用白色方块表示模拟波束的切换时间段。由于第一子帧中的第一符号预留了模拟波束的切换时间段,因此在第一子帧中可实现符号级粒度的模拟波束切换。
在本发明的一些实施例中,在无线帧的第一子帧中每隔至少N个符号后的每个符号也可以是不保留正常CP的一种结构,即每个符号用切换时间段替代正常CP的时间段用于模拟波束的切换,然后用切换时间段完成模拟波束间的切换,请参阅如图2-b所示,为本发明实施例中第一子帧的另一种帧结构示意图,其中,第一子帧包括两个时隙,以其中一个时隙的帧结构为例进行图示说明,1个时隙包括6个符号,每个符号用NCP-OFDM表示,在每个符号中不保留正常CP,将原来的正常CP替换为切换时间段,图中用灰色方块表示公共信道和/或公共参考信号,用白色方块表示模拟波束的切换时间段。由于第一子帧中的第一符号预留了模拟波束的切换时间段,因此在第一子帧中可实现符号级粒度的模拟波束切换。
进一步的,对于公共信道和/或公共参考信号具体表示信道的不同进行举例说明。如当前长期演进(Long Term Evolution,LTE)***中的PBCH在连续多个帧中的每个帧的第一个子帧的第二个时隙的前4个符号内进行传输,因此对于PBCH来说,模拟波束的切换可以是每隔4个符号的切换,即所述PBCH的模拟波束切换的间隔可以至少是4个符号。请参阅如图2-c所示,为本发明实施例中第一子帧传输PBCH的帧结构示意图,其中,一个PBCH传输持续时间为40毫秒(ms),一个无线帧为10ms,每个第一子帧包括2个时隙,每个时隙包括7个符号,PBCH在第一子帧的第二个时隙的前4个符号内传输。也就是说,当公共信道和/或公共参考信号具体为广播信道时,符号数N的取值为4,所以可以在第一子帧中每隔至少4个符号后的符号内预留时间段用于模拟波束的切换。
可以理解的是,本发明实施例中并不排除高频下广播信道的传输时序是不同于当前LTE的另一种设计,此时本发明实施例中模拟波束的切换仍然是适用的,并随着广播信道在传输子帧内占据的符号数自适应变化,也就是说,实际的切换跟着广播信道占据的符号数而变化。
请参阅如图2-d所示,为本发明实施例中第一子帧传输PSS/SSS的帧结构示意图,对于PSS/SSS来说,当前LTE FDD帧结构下,PSS/SSS分别在PSS/SSS
所在传输子帧的第一个时隙的最后两个符号上进行传输,即PSS和SSS分别占用一个符号,因此对于PSS/SSS来说模拟波束的切换可以是每隔2个符号的切换,即以两个符号的时间粒度进行模拟波束的切换,如在每两个符号的最后部分进行PSS/SSS所在传输子帧的模拟波束的切换。
对于PDCCH来说,当前LTE***下,可配置的符号数可以是1,2,3,4等中的任意一个。因此其所对应的模拟波束的切换时间段可以根据配置的PDCCH符号数为间隔进行,即至少隔N个符号后再进行PDCCH的模拟波束切换。
可以理解的是,在本发明的上述实施例中,不排除高频下上述公共信道和/或公共参考信号的传输时序是不同于当前LTE***的一种新设计,如所述***帧结构是不同于当前LTE***的一种结构,每个子帧内所述公共信道和或公共参考信号的符号数及上述公共信道和/或公共参考信号的位置也不同,但基本原理是类似的,即所述模拟波束的切换可以以所述公共信道和/或公共参考信号单次传输所占用的符号数有关,由于模拟波束的切换能支持到时域的最小粒度(即符号),因此其可灵活支持各种时域粒度的模拟波束切换,如可以是每隔至少一个符号,或者每隔至少一个时隙,或者每隔至少一个子帧,或者每隔至少一个无线帧等,具体取决于公共信道和/或公共参考信号的传输时序以及占用的符号数。
在本发明的一些实施例中,第一时间单元的配置信息,通过下行控制信令动态的通知给用户设备,或通过高层信令通知给用户设备。也就是说,基站可以采用下行控制信令动态的通知方式,也可以采用高层信令半静态的通知方式,例如,下行控制信令动态携带和通知,即在下行控制信令中携带第一时间单元的配置信息进行动态通知,可选的,所述通知同样可以是bitmap的指示信令。又如,基站可以采用高层信令半静态配置的方式,相对动态快速配置是长周期的配置,可选地,可通过无线资源控制(Radio Resource Control,RRC)信令或其他高层信令来半静态通知所述第一时间单元的配置信息,如由1bit高层信令来通知所述时间单元的类型是否为第一时间单元,或由高层信令配置一个第一时间单元集,所述配置可以为位图(bitmap)的形式。以无线时间窗具体为无线帧,时间单元具体为子帧为例,一个无线帧内的10个子帧的bitmap表示可以为:0011011001,代表了第三,四,六,七,十个子帧是第一子帧,
而其他子帧是第二子帧,这里假定0代表了第二子帧,1代表了第一子帧。当然也可以反过来表示。
在本发明的另一些实施例中,在向用户设备通知公共信道和/或公共参考信号传输占用第一时间单元的配置信息中,可以包括:第一时间单元的时间配比编号,其中,时间配比编号是按照配比周期确定的公共信道和/或公共参考信号传输占用的第一时间单元的一种配置。即在第一时间单元的配置信息中携带第一时间单元的时间配比编号,用户设备通过解析第一时间单元的配置信息确定第一时间单元的时间配比编号,通过具体的时间配比编号得到第一时间单元的具体配置情况。
举例说明如下,以无线时间窗具体为无线帧的情况下进行举例说明,第一时间单元具体为第一子帧,子时间单元具体为子帧中的符号,则第一子时间单元具体为第一子帧中的第一符号。将预留了切换时间段的第一子帧定义为切换子帧,公共信道和/或公共参考信号的模拟波束切换只能在所述切换子帧内进行,如图2-e所示,为本发明实施例提供的无线帧的一种帧结构示意图,每个子帧(subframe,sf)为1ms,一个无线帧共包括有10个sf,其中只有一些子帧为切换子帧(即第一子帧),基站可以预定义周期性的时间配比,高层信令通知不同的配比周期对应的时间配比编号,根据此编号对应的配置进行模拟波束的切换。请参阅如下表1所示,为本发明实施例提供的时间配比的一种配置表:
表1
具体的,上述表1中,表格中的每一行代表了一种子帧配比选项,表1中的S表示的是切换子帧,而N表示的是正常子帧,如第二行代表的是一种配比周期为5个子帧的切换配比选项,当假定一个帧包含的子帧数为10时,
此选项中的第0号子帧配置为切换子帧,第1,2,3,4号子帧配置为正常子帧,而第5号子帧配置为切换子帧,第6,7,8,9号子帧配置为正常子帧,因此其代表了一种配比周期为5的子帧配置。
在本发明的前述实施例中描述了第一子帧中预留切换时间段用于模拟波束的切换,进一步的,本发明通过以下实施例说明切换时间段的设置方式,具体的,切换时间段是根据预定义的切换时间配置索引确定的。对于切换时间段如何设置的实现方式中,可以预先定义切换时间配置索引,以一种配置索引对应一种时间长度,那么当选择了某一个切换时间配置索引后,就相当于明确了采用哪种时间长度作为切换时间段,从而可以确定模拟波束的切换时间段的时间长度,例如,请参阅如下表2所示,为本发明实施例提供的切换时间配置索引的一种配置表:
表2
配置索引 | 切换时间 |
0 | 0 |
1 | 1/4 |
2 | 1/3 |
3 | 1/2 |
4 | 3/4 |
5 | 2 |
6 | 1 |
例如,为支持灵活的切换时间,进一步高层信令通知切换时间配置索引(Index),根据此配置进行相应的切换时间段的时间长度设置。如当配置Index为0时代表没有设置切换时间,而配置Index为1时代表切换时间按照1/4个子时间单元的时间间隔进行设置。
在本发明的另一些实施例中,切换时间段的设置还可以有其他实现方式,比如可以是一种类似于现有标准中Extended CP的设计,以无线时间窗具体为无线帧的情况下进行举例说明,第一时间单元具体为第一子帧,子时间单元具体为子帧中的符号,则第一子时间单元具体为第一子帧中的第一符号。将第一子帧中不包含模拟波束的切换时间段时承载的符号数定义为N1而包含模拟波
束的切换时间段的第一子帧内的符号数定义为N2,N1>N2,即可将(子帧长度/N2-子帧长度/N1)做为模拟波束的切换时间段的时间长度。
在本发明的一些实施例中,所述时间单元确定模块101,还用于确定所述无线时间窗中第二时间单元的配置信息,其中,所述第二时间单元包括多个子时间单元,所述第二时间单元中预留最后M个子时间单元组成切换时间段,所述第二时间单元内的切换时间段用于业务信道进行模拟波束的切换,所述M为自然数;
所述数据传输模块102,还用于根据所述第二时间单元的配置信息在所述第二时间单元传输所述业务信道,其中,所述业务信道在所述第二时间单元内除所述最后M个子时间单元之外的子时间单元上传输。
在本发明的前述实施例中描述了无线时间窗中的第一时间单元中预留出切换时间段用于模拟波束的切换,时间单元确定模块101可执行的步骤为:在该无线时间窗中除了包括第一时间单元之外,还包括第二时间单元,与第一时间单元不同的是,第二时间单元是用于传输业务信道的时间单元。可选地,第一时间单元中预留了用于模拟波束切换的切换时间段的第一子时间单元的时间长度大于或等于第一或第二时间单元中未预留切换时间段的子时间单元的时间长度。即,第一时间单元的第一子时间单元对应的子载波间隔小于或等于第一或第二时间单元中未预留切换时间段的子时间单元对应的子载波间隔。进一步的可进行如设置:第二时间单元包含的子时间单元个数大于等于第一时间单元包含的子时间单元个数。通过在无线时间窗中设置具体不同配置的时间单元,可以按照传输数据的不同来具体选用某种配置的时间单元。
例如,无线时间窗具体为无线帧,第一时间单元具体为第一子帧,子时间单元具体为子帧中的符号,第二时间单元具体为第二子帧,第一子帧用于传输公共信道和/或公共参考信号,与第一子帧不同的是,第二子帧是用于传输业务信道的子帧,在实际***中,业务信道的传输和信道质量信息的测量是基于每子帧的,因此其每次数据传输所采用的模拟波束的切换和变化通常是基于每子帧的,所以在第二子帧中也就不需要在每个符号中都预留切换时间段用于模拟波束的切换,而是可以在每个第二子帧内预留最后M个符号作为模拟波束切换的切换时间段,例如M为2时,只在每个第二子帧内预留最后2个符号用于模拟波束的切换,而在第二子帧除最后2个符号以外的其它符号内传输业
务信道,可选地第二子帧的每个符号都保留正常CP。数据传输模块102执行的步骤为:第二时间单元中最后M个子时间单元被用作模拟波束切换的切换时间段,业务信道在第二时间单元中除最后M个子时间单元以外的其它子时间单元传输。例如,在第二时间单元中共有10个子时间单元,若M的取值为3,则第二时间单元中,第8,9,10三个子时间单元用作模拟波束切换的的切换时间段,第1,2,3,4,5,6,7共7个子时间单元可用于传输业务信道。
在本发明的另一些实施例中,所述时间单元确定模块101,还用于确定所述无线时间窗中第二时间单元的配置信息,其中,所述第二时间单元包括多个子时间单元,所述第二时间单元中的最后一个子时间单元内预留切换时间段和传输时间段,所述第二时间单元内的切换时间段用于业务信道进行模拟波束的切换;
所述数据传输模块102,还用于根据所述第二时间单元的配置信息在所述第二时间单元传输所述业务信道,其中,所述业务信道在所述第二时间单元内除所述最后一个子时间单元之外的子时间单元和所述最后一个子时间单元内的传输时间段上传输。
进一步的,所述第二时间单元的最后一个子时间单元内传输时间段的时间段长度小于等于所述第二时间单元内除所述最后一个子时间单元的其他子时间单元内用于所述业务信道传输的时间段长度。
在本发明的前述实施例中描述了无线时间窗中的第一时间单元中预留切换时间段用于模拟波束的切换,时间单元确定模块101可执行的步骤为:在该无线时间窗中除了包括第一时间单元之外,还包括第二时间单元,与第一时间单元不同的是,第二时间单元是用于传输业务信道的时间单元,例如,无线时间窗具体为无线帧,第一时间单元具体为第一子帧,子时间单元具体为子帧中的符号,第二时间单元具体为第二子帧,第一子帧用于传输公共信道和/或公共参考信号,与第一子帧不同的是,第二子帧是用于传输业务信道的子帧,在实际***中,业务信道的传输和信道质量信息的测量是基于每子帧的,因此其每次数据传输所采用的模拟波束的切换和变化通常是基于每子帧的,所以在第二子帧中也就不需要在每个符号中都预留切换时间段用于模拟波束的切换,而是可以在每个第二子帧中最后一个符号内预留切换时间段和传输时间段,该切换时间段用于模拟波束的切换。数据传输模块102可执行的步骤为:第二时间
单元中最后一个子时间单元中预留模拟波束切换的切换时间段,那么在第二时间单元中除最后一个子时间单元外的子时间单元仍是空闲的,业务信道可以在第二时间单元中除最后一个子时间单元以外的其它子时间单元来传输。另外在第二时间单元中最后一个子时间单元内预留的传输时间段也可以用作业务信道的传输。
可选的,在本发明的一些实施例中,第二时间单元的最后一个子时间单元内传输时间段的时间段长度小于等于第二时间单元内除最后一个子时间单元的其他子时间单元内用于业务信道传输的时间段长度。例如,在第二时间单元中最后一个子时间单元内切换时间段用作模拟波束的切换,也就是说在第二时间单元的最后一个子时间单元内只能在除切换时间段以外的传输时间段传输业务信道,而在第二时间单元中除最后一个子时间单元以外的其他子时间单元内不需要预留用作模拟波束切换的切换时间段,此时最后一个子时间单元内用于业务信道传输的时间段长度小于第二时间单元内除最后一个子时间单元的其他子时间单元内用于业务信道传输的时间段长度。
举例说明如下,以无线时间窗具体为无线帧的情况下进行举例说明,第一时间单元具体为第一子帧,第二时间单元具体为第二子帧,子时间单元具体为子帧中的符号,则第一子时间单元具体为第一子帧中的第一符号。具体的,模拟波束可以在第二子帧的最后M个符号内保留正常CP,且在第二子帧的最后M个符号的尾部预留切换时间段用于模拟波束的切换;或,将第二子帧的最后M个符号内的正常CP替换为模拟波束的切换时间段;或,在第二子帧的最后M个符号内不传输业务信道,且第二子帧的最后M个符号全部用于模拟波束的切换。也就是说,可以在第二子帧的最后M个符号内仍然保留有正常CP,模拟波束切换的切换时间段占用的是第二子帧的最后M个符号的尾部,这样可以保留无线帧中的原有的正常CP。或者,确定在第二子帧的最后M个符号内预留切换时间段时,预留的切换时间段占用了正常CP,从而正常CP可以替换为模拟波束切换的切换时间段,或者,在第二子帧的最后M个符号内不传输业务信道,业务信道只在第二子帧的除最后M个符号以外的其它符号内传输,那么最后M个符号全部用作模拟波束的切换时间段。
需要说明的是,在本发明的前述实施例中,由于最后一个符号的设计和前面符号不同(最后一个符号增加了模拟波束的切换时间段的预留),因此第二
子帧中每子帧的最后一个符号的子载波间隔需变大以保证最后一个符号的长度和前面其他符号的长度相等,即最后一个符号的子载波间隔大于其他符号的子载波间隔。或在进行模拟波束切换的子帧,数据传输时打掉最后一个符号,即最后一个符号不用于业务信道传输,而是全部用于模拟波束的切换。
举例说明如下:业务信道的传输通常以一个子帧为最小时间粒度,且信道质量信息(如预编码信息,秩指示信息等)的测量和反馈也是基于一个子帧的,即子帧级的模拟波束的切换时间预留就足够了,所以业务信道的传输可基于第二子帧进行,第二子帧在每子帧的最后一个符号中预留一段空CP时间段用来做模拟波束切换的切换时间段。从而模拟波束的切换以一个子帧的粒度进行,同理,第二子帧内的最后一个符号可以是保留正常CP时间段的一种结构,如基于当前OFDM符号,即保留当前OFDM符号中的正常CP在每符号的最后预留一部分模拟波束的切换时间,而最后一个符号外的其他符号仍然保持正常的CP和有效数据部分的结构,请参阅如图2-f所示,为本发明实施例提供的第二子帧的一种帧结构示意图。
又如,第二子帧的最后一个符号也可以是不保留正常CP时间段的结构,即最后一个符号用空CP时间段替代正常的CP时间段来完成模拟波束的切换,而最后一个符号外的其他符号仍然保持正常CP和有效数据部分的结构。请参阅如图2-g所示,为本发明实施例提供的第二子帧的另一种帧结构示意图。
可选地,在无线帧的第二子帧的每个时隙中预留切换时间段用于模拟波束的切换,即可以以时隙级或子帧级别来预留切换时间段,请参阅如图2-h所示,为本发明实施例提供的第二子帧的另一种帧结构示意图,1sf表示一个第二子帧,每个第二子帧包括2个时隙,白色方块表示业务信道,黑色方块表示模拟波束的切换时间段。不失一般性,也可以以无限帧或超帧为粒度来预留所述模拟波束切换的切换时间段,如以无线帧为粒度时,两次模拟波束切换的切换时间段的时间间隔大于或等于1个无线帧的长度。
在本发明的一些实施例中,请参阅如图1-b所示,所述数据传输的装置100还包括:配置模块103,用于为用户设备配置在所述第一时间单元内每个子时间单元上对导频资源进行信道状态信息(Channel State Information,CSI)测量的进程。
也就是说,本发明实施例可以包括为用户设备配置在第一时间单元内对导
频信号进行CSI测量的进程。例如,在第一时间单元的第一子时间单元传输公共信道和/或公共参考信号的同时,为用户设备配置在第一时间单元内对导频信号进行CSI测量的进程。举例说明如下,以无线时间窗具体为无线帧的情况下进行举例说明,第一时间单元具体为第一子帧,第二时间单元具体为第二子帧,子时间单元具体为子帧中的符号,则第一子时间单元具体为第一子帧中的第一符号,进一步的,为了确定第一子帧和第二子帧之间包括的符号个数的数量关系,可以将第一子帧和第二子帧的时间长度对齐,即在第一子帧和第二子帧的时间长度保持一致的情况下,由于第一子帧中的符号长度大于或等于第二子帧中的符号长度,故确定第一子帧的符号数小于或等于第二子帧的符号数。
在前述实施例中,第一子帧中可以只用来传输公共信道和/或公共参考信号,此时每子帧的每符号内的整个带宽上全部用来传输公共信道和/或公共参考信号,所述公共信道和一些公共参考信号包括但不限于控制信道,同步信号,广播信道,控制格式指示信道,成功/失败(ACK/NAK)信息传输信道等。但是由于所述公共信道/信号的传输比特数相对较小,因此通常不需要在全带宽上进行传输。因此第一子帧中同时也可以允许业务信道的传输,具体为在每符号的公共信道传输的同时业务信道也可以进行相应的传输,由于公共信道和或公共参考信号的模拟波束切换是符号级的,因此不同符号上的模拟波束可能是不同的,此时可进行每符号的CSI测量和上报,即进行符号级的测量导频资源,例如信道状态信息-参考信号(Reference Signal,RS)资源的配置,和相应的符号级的CSI测量和上报,包括符号级的CSI process触发和上报等。基站在第一子帧内触发用户设备执行符号级的CSI测量和反馈,其中,基站同时需配置和通知每个用户设备在第一子帧内的哪些符号上进行同类CSI的测量和反馈(如有相同CSI-RS配置的符号属于同一类,即一套CSI-RS配置对应一类CSI测量和反馈,或对应相同模拟波束的CSI-RS资源配置及相应的CSI测量属于同类CSI),而在其他子帧触发和配置子帧级的CSI测量和配置,其中,用户设备进行CSI的测量和反馈可参阅现有技术,此处不再赘述。基于第一子帧内各个符号上的不同类(或不同模拟波束)CSI的测量信息,基站选择一个最优CSI信息对应的模拟波束,在第二子帧上可根据第一子帧内的测量结果决定是否进行模拟波束的切换及切换后的最优模拟波束。
需要说明的是,现有技术中对无线帧上传输的数据不做区分,所以不管公
共信道和或公共参考信号和业务信道均在每个子帧的每个符号上预留一段空CP用作模拟波束的切换,而本发明实施例中,首先数据传输的装置在不同信道采用不同的子帧类型和切换时间预留的方法,具体为公共信道的每个传输子帧(即第一子帧)按照公共信道占用的符号数预留切换时间段,而业务信道的每个传输帧只在每个子帧(第二类子帧)的最后一个或几个符号预留转换时间段,另外,本发明实施例中,第一子帧或第二子帧中的每个符号进一步可以是基于OFDM基础上的一种新结构,既保留了每个符号中的正常CP,又预留了切换时间段,这些操作既能保留OFDM的正交性又将控制和业务分别处理,从而减小了开销。
通过以上实施例对本发明的描述可知,首先确定无线时间窗中第一时间单元的配置信息,该第一时间单元包括多个子时间单元,在第一时间单元中每隔至少N个子时间单元后的第一子时间单元内预留切换时间段和传输时间段,切换时间段用作公共信道和/或公共参考信号进行模拟波束的切换,然后根据第一时间单元的配置信息在第一时间单元的第一子时间单元传输公共信道和/或公共参考信号,则公共信道和/或公共参考信号在第一子时间单元内的传输时间段内传输。由于在无线时间窗中第一时间单元中每隔至少N个子时间单元后的第一子时间单元内预留了切换时间段用于模拟波束的切换,故可以在该切换时间段内按照天线阵子的虚拟加权进行模拟波束的切换,公共信道和/或公共参考信号不在切换时间段内传输,而是在第一子时间单元中的传输时间段传输。由于预设切换时间段所属的第一子时间单元是第一时间单元中每隔至少N个子时间单元后的子时间单元,所以不需要在无线时间窗中每个时间单元的每个子时间单元都设置切换时间段,从而可以避免资源的浪费。
前述实施例介绍了本发明实施例提供的一种数据传输的装置,接下来介绍本发明实施例提供的另一种数据传输的装置,请参阅图3-a所示,本发明实施例提供的一种数据传输的装置300,可以包括:时间单元确定模块301、数据传输模块302,其中,
时间单元确定模块301,用于确定无线时间窗中第二时间单元的配置信息,其中,所述第二时间单元包括多个子时间单元,所述第二时间单元中预留最后M个子时间单元组成切换时间段,所述切换时间段用于业务信道进行模
拟波束的切换,所述M为自然数;
数据传输模块302,用于根据所述第二时间单元的配置信息在所述第二时间单元传输所述业务信道,其中,所述业务信道在所述第二时间单元内除所述最后M个子时间单元之外的子时间单元上传输。
本发明的一些实施例中,所述第二时间单元的配置信息,包括:所述第二时间单元的时间配比编号,所述时间配比编号是按照配比周期确定的所述第二时间单元的配置。
在本发明的一些实施例中,所述数据传输模块302,还用于将所述第二时间单元的配置信息,通过下行控制信令动态的通知给用户设备,或通过高层信令通知给用户设备。
在本发明的一些实施例中,所述时间单元确定模块301,还用于确定所述无线时间窗中第一时间单元的配置信息,其中,所述第一时间单元包括多个子时间单元,所述第一时间单元中每隔至少N个子时间单元后的第一子时间单元内预留切换时间段和传输时间段,所述第一子时间单元内的切换时间段用于公共信道和/或公共参考信号进行模拟波束的切换,所述N为自然数;
所述数据传输模块302,还用于根据所述第一时间单元的配置信息在所述第一时间单元的第一子时间单元传输所述公共信道和/或公共参考信号,其中,所述公共信道和/或公共参考信号在所述第一子时间单元内的传输时间段内传输。
在本发明的一些实施例中,请参阅如图3-b所示,所述数据传输的装置300还包括:配置模块303,用于为用户设备配置在所述第一时间单元内每个子时间单元上对导频资源进行信道状态信息测量的进程。
在本发明的一些实施例中,所述第二时间单元包含的子时间单元个数大于等于所述第一时间单元包含的子时间单元个数。
需要说明的是,对于时间单元确定模块301和数据传输模块302,与前述图1-a和图1-b中所示的实施例中描述的时间单元确定模块101和数据传输模块102相类似,可参阅前述实施例中的具体说明,此处不再赘述。
在本发明的一些实施例中,模拟波束切换的切换时间段是无线时间窗中的第二时间单元内最后M个子时间单元,该切换时间段的时间长度是根据预定义的切换时间配置索引确定的。例如可结合前述表2的举例说明。
在本发明的一些实施例中,第二时间单元的配置信息,包括:第二时间单元的时间配比编号,时间配比编号是按照配比周期确定的业务信道传输占用的第二时间单元的配置。例如可结合前述表1的举例说明。
在本发明的一些实施例中,第二时间单元的配置信息,通过下行控制信令动态的通知给用户设备,或通过高层信令通知给用户设备。也就是说,基站为了向用户设备通知第二时间单元中用于业务信道的传输的子时间单元配置情况,基站可以采用下行控制信令动态的通知方式,也可以采用高层信令半静态的通知方式,例如,下行控制信令动态携带和通知,即在下行控制信令中携带第二时间单元的配置信息进行动态通知,所述通知同样可以是个1bit的指示信令(指示当前时间单元的类型是否为第二时间单元)。又如,基站可以采用高层信令半静态配置的方式,相对动态快速配置是更长周期的配置,可选地,可通过RRC信令或其他高层信令来半静态通知所述第二时间单元的配置信息,如由1bit高层信令来通知所述时间单元的类型为第二时间单元,或由高层信令配置一个第二时间单元集,所述配置可以为位图(bitmap)的形式。
通过以上实施例对本发明的描述可知,首先确定无线时间窗中第二时间单元的配置信息,第二时间单元包括多个子时间单元,在第二时间单元中预留最后M个子时间单元组成切换时间段,该切换时间段用于业务信道进行模拟波束的切换,然后根据第二时间单元的配置信息在第二时间单元的除最后M个子时间单元以外的子时间单元上传输业务信道,由于在无线时间窗中第二时间单元预留了最后M个子时间单元用于模拟波束的切换,故可以在该切换时间段内按照天线阵子的虚拟加权进行模拟波束的切换,由于预设切换时间段是第二时间单元中最后M个子时间单元来组成,所以不需要在无线时间窗中第二时间单元的每个子时间单元都设置切换时间段,从而可以避免资源的浪费。
前述实施例介绍了本发明实施例提供的一种数据传输的装置,接下来介绍本发明实施例提供的另一种数据传输的装置,该数据传输的装置与如图3-a、图3-b中所示的数据传输的装置不同,具体的,请参阅如图4所示,数据传输的装置400,可以包括:时间单元确定模块401、数据传输模块402,其中,
时间单元确定模块401,用于确定无线时间窗中第二时间单元的配置信息,其中,所述第二时间单元包括多个子时间单元,所述第二时间单元中的最后一个子时间单元内预留切换时间段和传输时间段,所述切换时间段用于业务
信道进行模拟波束的切换;
数据传输模块402,用于根据所述第二时间单元的配置信息在所述第二时间单元传输所述业务信道,其中,所述业务信道在所述第二时间单元内除所述最后一个子时间单元之外的子时间单元和所述最后一个子时间单元内的传输时间段上传输。
在本发明的一些实施例中,所述第二时间单元的配置信息,包括:所述第二时间单元的时间配比编号,所述时间配比编号是按照配比周期确定的所述第二时间单元的配置。
在本发明的一些实施例中,所述数据传输模块402,还用于将所述第二时间单元的配置信息,通过下行控制信令动态的通知给用户设备,或通过高层信令通知给用户设备。
在本发明的一些实施例中,模拟波束切换的切换时间段位于无线时间窗中的第二时间单元内的最后一个子时间单元中,该切换时间段的时间长度是根据预定义的切换时间配置索引确定的。例如可结合前述表2的举例说明。
在本发明的一些实施例中,第二时间单元的配置信息,包括:第二时间单元的时间配比编号,时间配比编号是按照配比周期确定的业务信道传输占用的第二时间单元的配置。例如可结合前述表1的举例说明。
在本发明的一些实施例中,第二时间单元的配置信息,通过下行控制信令动态的通知给用户设备,或通过高层信令通知给用户设备。也就是说,基站为了向用户设备通知第二时间单元中用于业务信道的传输的子时间单元配置情况,基站可以采用下行控制信令动态的通知方式,也可以采用高层信令半静态的通知方式,例如,下行控制信令动态携带和通知,即在下行控制信令中携带第二时间单元的配置信息进行动态通知,所述通知同样可以是个1bit的指示信令(指示当前时间单元的类型是否为第二时间单元)。又如,基站可以采用高层信令半静态配置的方式,相对动态快速配置是更长周期的配置,可选地,可通过RRC信令或其他高层信令来半静态通知所述第二时间单元的配置信息,如由1bit高层信令来通知所述时间单元的类型为第二时间单元,或由高层信令配置一个第二时间单元集,所述配置可以为位图(bitmap)的形式。
在本发明的一些实施例中,所述时间单元确定模块401,还用于确定所述无线时间窗中第一时间单元的配置信息,其中,所述第一时间单元包括多个子
时间单元,所述第一时间单元中每隔至少N个子时间单元后的第一子时间单元内预留切换时间段和传输时间段,所述第一子时间单元内的切换时间段用于公共信道和/或公共参考信号进行模拟波束的切换,所述N为自然数;
所述数据传输模块402,还用于根据所述第一时间单元的配置信息在所述第一时间单元的第一子时间单元传输所述公共信道和/或公共参考信号,其中,所述公共信道和/或公共参考信号在所述第一子时间单元内的传输时间段内传输。
通过以上实施例对本发明的描述可知,首先确定无线时间窗中第二时间单元的配置信息,第二时间单元包括多个子时间单元,在第二时间单元中最后一个子时间单元内预留切换时间段和传输时间段,切换时间段用作进行模拟波束的切换,然后根据第二时间单元的配置信息在第二时间单元内除最后一个子时间单元之外的子时间单元和最后一个子时间单元内除切换时间段之外的传输时间段上传输,由于在无线时间窗中第二时间单元预留了最后一个子时间单元的切换时间段用于模拟波束的切换,故可以在该切换时间段内按照天线阵子的虚拟加权进行模拟波束的切换,由于预设切换时间段由第二时间单元中最后一个子时间单元的切换时间段来组成,所以不需要在无线时间窗中第二时间单元的每个子时间单元都设置切换时间段,从而可以避免资源的浪费。
前述实施例介绍了本发明实施例提供的一种数据传输的装置,接下来介绍本发明实施例提供的另一种数据传输的装置,请参阅如图5所示,本发明实施例提供的一种数据传输的装置500,可以包括:时间单元确定模块501、数据传输模块502,其中,
时间单元确定模块501,用于确定无线时间窗中第三时间单元的配置信息,其中,第三时间单元包括多个子时间单元,所述第三时间单元中预留最后M个子时间单元组成切换时间段,所述切换时间段用于公共信道或公共参考信号或业务信道进行模拟波束的切换,所述M为自然数;
数据传输模块502,用于根据所述第三时间单元的配置信息在所述第三时间单元传输所述公共信道或公共参考信号或业务信道,其中,所述公共信道或公共参考信号或业务信道在所述第三时间单元内除所述最后M个子时间单元之外的子时间单元上传输。
在本发明的一些实施例中,所述第三时间单元的配置信息,包括:所述第三时间单元的时间配比编号,所述时间配比编号是按照配比周期确定的所述公共信道或公共参考信号或业务信道传输占用的第三时间单元的配置。
在本发明的一些实施例中,所述数据传输模块502,还用于将所述第三时间单元的配置信息,通过下行控制信令动态的通知给用户设备,或通过高层信令通知给用户设备。
在本发明实施例中,时间单元确定模块501对需要在无线时间窗内传输的数据进行分类,并针对不同类别的数据采用与数据自身传输相适配的切换时间段设置方式,其中,无线时间窗指的是无线信号传输使用的时域资源,例如结合具体的应用场景,一个无线时间窗可以指的是一个广义的无线传输时间单位,也可以指的是一个具体的传输时间单位,如一个超帧,或当前LTE中的一个无线帧,或子帧,时隙等。每个无线时间窗中的所有时间单元划分为三类,除了前述实施例中描述的第一时间单元、第二时间单元之外,每个无线时间窗中还包括一类时间单元,定义为第三时间单元,在第三时间单元中预留出M个子时间单元组成切换时间段,切换时间段用作公共信道或公共参考信号或业务信道进行模拟波束切换,这里所述的模拟波束切换可以指前述实施例中描述的模拟波束切换。也就是说,第三时间单元中预留的切换时间段可以用作模拟波束的切换。
例如,无线时间窗具体为无线帧,第一时间单元具体为第一子帧,子时间单元具体为子帧中的符号,第三时间单元具体为第三子帧,与第一子帧、第二子帧不同的是,第三子帧是用于传输公共信道或公共参考信号或业务信道的子帧,在第三子帧中不需要在每个符号中都预留时间段用于模拟波束的切换,而是可以在每个第三子帧内预留最后M个符号用于模拟波束的切换,例如M为2时,只在每个第三子帧内预留最后2个符号用于模拟波束的切换,而在第三子帧除最后2个符号以外的其它符号内传输公共信道或公共参考信号或业务信道。
在本发明实施例中,第三时间单元中最后M个子时间单元被用作模拟波束的切换时间段,那么在第三时间单元中除最后M个子时间单元以外的其它子时间单元上传输公共信道或公共参考信号或业务信道。
在本发明的一些实施例中,模拟波束切换的切换时间段是无线时间窗中的
第三时间单元内最后M个子时间单元,该切换时间段的时间长度是根据预定义的切换时间配置索引确定的。例如可结合前述表2的举例说明。
在本发明的一些实施例中,第三时间单元的配置信息,包括:第三时间单元的时间配比编号,时间配比编号是按照配比周期确定的所述公共信道或公共参考信号或业务信道传输占用的第三时间单元的配置。例如可结合前述表1的举例说明。
在本发明的一些实施例中,第三时间单元的配置信息,通过下行控制信令动态的通知给用户设备,或通过高层信令通知给用户设备。也就是说,基站为了向用户设备通知第三时间单元中用于业务信道的传输的子时间单元配置情况,基站可以采用下行控制信令动态的通知方式,也可以采用高层信令半静态的通知方式,例如,下行控制信令动态携带和通知,即在下行控制信令中携带第三时间单元的配置信息进行动态通知,所述通知同样可以是个1bit的指示信令(指示当前时间单元的类型是否为第三时间单元)。又如,基站可以采用高层信令半静态配置的方式,相对动态快速配置是更长周期的配置。
通过以上实施例对本发明的描述可知,首先确定无线时间窗中第三时间单元的配置信息,第三时间单元包括多个子时间单元,在第三时间单元中预留最后M个子时间单元组成公共信道或公共参考信号或业务信道进行模拟波束切换的切换时间段,然后根据第三时间单元的配置信息在第三时间单元的除最后M个子时间单元以外的子时间单元上传输公共信道或公共参考信号或业务信道,由于在无线时间窗中第三时间单元预留了最后M个子时间单元用于模拟波束的切换,故可以在该切换时间段内按照天线阵子的虚拟加权进行模拟波束的切换,由于预设切换时间段是第三时间单元中最后M个子时间单元来组成,所以不需要在无线时间窗中第三时间单元的每个子时间单元都设置切换时间段,从而可以避免资源的浪费。

通过以上实施例对本发明的描述可知,首先确定无线时间窗中第二时间单元的配置信息,在第二时间单元中预留最后M个子时间单元组成切换时间段,该切换时间段用于业务信道进行模拟波束的切换,然后根据第二时间单元的配置信息在第二时间单元的除最后M个子时间单元以外的子时间单元上传输业务信道,由于在无线时间窗中第二时间单元预留了最后M个子时间单元用于模拟波束的切换,故可以在该切换时间段内按照天线阵子的虚拟加权进行模拟波束的切换,由于预设切换时间段是第二时间单元中最后M个子时间单元来
组成,所以不需要在无线时间窗中第二时间单元的每个子时间单元都设置切换时间段,从而可以避免资源的浪费。
前述实施例介绍了本发明实施例提供的一种数据传输的方法,接下来介绍本发明实施例提供的另一种数据传输的方法,该数据传输的方法与如图3-a所示的数据传输的方法不同,具体的,请参阅如图15所示,主要可以包括如下步骤:

配置一个第二时间单元集,所述配置可以为位图(bitmap)的形式。
在本发明的一些实施例中,数据传输的方法除了包括前述实施例中描述的方式外,还可以包括如下步骤:
D1、确定无线时间窗中第一时间单元的配置信息,其中,第一时间单元包括多个子时间单元,第一时间单元中每隔至少N个子时间单元后的第一子时间单元内预留切换时间段和传输时间段,第一子时间单元内的切换时间段用于公共信道和/或公共参考信号进行模拟波束的切换,N为自然数;

对于步骤D1和步骤D2,与前述实施例中描述的步骤101和步骤102相类似,可参阅前述实施例中的具体说明,此处不再赘述。
通过以上实施例对本发明的描述可知,首先确定无线时间窗中第二时间单元的配置信息,在第二时间单元中最后一个子时间单元内预留切换时间段和传输时间段,切换时间段用作进行模拟波束的切换,然后根据第二时间单元的配置信息在第二时间单元内除最后一个子时间单元之外的子时间单元和最后一个子时间单元内的传输时间段上传输,由于在无线时间窗中第二时间单元预留了最后一个子时间单元的切换时间段用于模拟波束的切换,故可以在该切换时间段内按照天线阵子的虚拟加权进行模拟波束的切换,由于预设切换时间段是第二时间单元中最后一个子时间单元的切换时间段来组成,所以不需要在无线时间窗中第二时间单元的每个子时间单元都设置切换时间段,从而可以避免资源的浪费。
前述实施例介绍了本发明实施例提供的一种数据传输的方法,接下来介绍本发明实施例提供的另一种数据传输的方法,请参阅如图16所示,主要可以包括如下步骤:
1601、确定无线时间窗中第三时间单元的配置信息。
其中,第三时间单元包括多个子时间单元,第三时间单元中预留最后M个子时间单元组成切换时间段,切换时间段用于公共信道或公共参考信号或业务信道进行模拟波束的切换,M为自然数。
1602、根据第三时间单元的配置信息在第三时间单元传输公共信道或公共
参考信号或业务信道。
其中,公共信道或公共参考信号或业务信道在第三时间单元内除最后M个子时间单元之外的子时间单元上传输。
在本发明实施例中,对需要在无线时间窗内传输的数据进行分类,并针对不同类别的数据采用与数据自身传输相适配的切换时间段设置方式,其中,无线时间窗指的是无线信号传输使用的时域资源,例如结合具体的应用场景,一个无线时间窗可以指的是一个广义的无线传输时间单位,也可以指的是一个具体的传输时间单位,如一个超帧,或当前LTE中的一个无线帧,或子帧,时隙等。每个无线时间窗中的所有时间单元划分为三类,除了前述实施例中描述的第一时间单元、第二时间单元之外,每个无线时间窗中还包括一类时间单元,定义为第三时间单元,在第三时间单元中预留出M个子时间单元组成切换时间段,切换时间段用作公共信道或公共参考信号或业务信道进行模拟波束切换,这里所述的模拟波束切换可以指前述实施例中描述的模拟波束切换。也就是说,第三时间单元中预留的切换时间段可以用作模拟波束的切换。
例如,无线时间窗具体为无线帧,第一时间单元具体为第一子帧,子时间单元具体为子帧中的符号,第三时间单元具体为第三子帧,与第一子帧、第二子帧不同的是,第三子帧是用于传输公共信道或公共参考信号或业务信道的子帧,在第三子帧中不需要在每个符号中都预留时间段用于模拟波束的切换,而是可以在每个第三子帧内预留最后M个符号用于模拟波束的切换,例如M为2时,只在每个第三子帧内预留最后2个符号用于模拟波束的切换,而在第三子帧除最后2个符号以外的其它符号内传输公共信道或公共参考信号或业务信道。
在步骤1602中,第三时间单元中最后M个子时间单元被用作模拟波束的切换时间段,那么在第三时间单元中除最后M个子时间单元以外的其它子时间单元上传输公共信道或公共参考信号或业务信道。
在本发明的一些实施例中,模拟波束切换的切换时间段是无线时间窗中的第三时间单元内最后M个子时间单元,该切换时间段的时间长度是根据预定义的切换时间配置索引确定的。例如可结合前述表2的举例说明。
在本发明的一些实施例中,第三时间单元的配置信息,包括:第三时间单元的时间配比编号,时间配比编号是按照配比周期确定的所述公共信道或公共
参考信号或业务信道传输占用的第三时间单元的配置。例如可结合前述表1的举例说明。
在本发明的一些实施例中,第三时间单元的配置信息,通过下行控制信令动态的通知给用户设备,或通过高层信令通知给用户设备。也就是说,基站为了向用户设备通知第三时间单元中用于业务信道的传输的子时间单元配置情况,基站可以采用下行控制信令动态的通知方式,也可以采用高层信令半静态的通知方式,例如,下行控制信令动态携带和通知,即在下行控制信令中携带第三时间单元的配置信息进行动态通知,所述通知同样可以是个1bit的指示信令(指示当前时间单元的类型是否为第三时间单元)。又如,基站可以采用高层信令半静态配置的方式,相对动态快速配置是更长周期的配置。
通过以上实施例对本发明的描述可知,首先确定无线时间窗中第三时间单元的配置信息,在第三时间单元中预留最后M个子时间单元组成切换时间段,切换时间段用于公共信道或公共参考信号或业务信道进行模拟波束的切换,然后根据第三时间单元的配置信息在第三时间单元的除最后M个子时间单元以外的子时间单元上传输公共信道或公共参考信号或业务信道,由于在无线时间窗中第三时间单元预留了最后M个子时间单元用于模拟波束的切换,故可以在该切换时间段内按照天线阵子的虚拟加权进行模拟波束的切换,由于预设切换时间段是第三时间单元中最后M个子时间单元来组成,所以不需要在无线时间窗中第三时间单元的每个子时间单元都设置切换时间段,从而可以避免资源的浪费。
