具体实施方式
为使本公开文本实施例的目的、技术方案和优点更加清楚,下面将结合本公开文本实施例中的附图,对本公开文本实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本公开文本一部分实施例,而不是全部的实施例。基于本公开文本中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本公开文本保护的范围。
本公开文本针对相关技术中的在没有基站下发的PDCCH信令时,终端无法确定自身可占用资源的大小,无法保证通信可靠性的问题,提供一种数据传输方法及终端。
在本公开文本一些实施例中,如图1所示,提供一种数据传输方法,应用于终端侧,包括:
步骤11,获取网络中当前的信道占用信息;
需要说明的是,在本实施例中该信道占用信息可以为信道占空比,也可 以为信道占用功率测量值小于或等于预设值的资源比重。
步骤12,根据所述信道占用信息,确定用于传输数据的资源信息;
该步骤中,通过信道占用信息便可以确定出网络中可用于终端进行传输数据的资源信息,其中,该资源信息主要指的是资源的大小。
步骤13,根据所述资源信息,进行数据的传输。
需要说明的是,在进行通信数据的传输前,通常是由终端的高层利用该资源信息,对将要传输的数据包进行分段,以使得数据适于在该资源上传输。
需要说明的是,本公开文本实施例主要应用于终端需要与外部设备通信,但是终端没有与基站进行交互,不能明确知道信道中有多少资源可以使用的情形,本公开文本实施例中,终端通过利用自身获取的信道占用信息,确定用于传输数据的资源信息,进而实现与外部设备的通信,此种方式实现了终端高层数据包与资源的适配,保证了网络通信的可靠性。
在本公开文本一些实施例中,如图2所示提供一种数据传输方法,应用于终端侧,包括:
步骤21,获取网络中当前的信道统计信息;
需要说明的是,该信道统计信息通常指的是对信道中的原始信息进行测量得到的测量信息,可以是信道中资源占用空闲的列表信息,也可以是测量得到的信道中资源的信号功率信息。
步骤22,根据所述信道统计信息,获取当前的信道占用信息;
本实施例中,当所述信道统计信息为信道中资源占用空闲的列表信息时,所述信道占用信息为信道占空比;当所述信道统计信息为测量得到的信道中资源的信号功率信息时,所述信道占用信息为信道占用功率测量值小于或等于预设值的资源比重。
步骤23,根据所述信道占用信息,确定用于传输数据的资源信息;
该步骤中,通过信道占用信息便可以确定出网络中可用于终端进行传输数据的资源信息,其中,该资源信息主要指的是资源的大小。
步骤24,根据所述资源信息,进行数据的传输。
需要说明的是,在进行通信数据的传输前,通常是由终端的高层利用该资源信息,对将要传输的数据包进行分段,以使得数据适于在该资源上传输。
通常情况下,该数据传输方法在终端的底层实现,该底层可以是终端在逻辑上划分的物理层,也可以是MAC层。
可选地,步骤21在实现时,包括以下两种实现方式:
方式一、通过终端的物理层获取当前的信道统计信息。
需要说明的是,终端的物理层可以实现对信道信息的测量,在使用时,只需要从物理层获取到测量得到的信道统计信息即可。
方式二、通过终端的高层信令获取当前的信道统计信息。
此方式二针对的是,终端的物理层没有测量得到的信道统计信息,但是终端通过与其他的设备通信,得到了当前网络下的信道统计信息,因终端与其他设备交互得到的信息最终会传递到终端的高层,由高层进行解析,所以终端在使用该信道统计信息时,需要由终端的高层信令传递该信道统计信息给终端的底层。
方式三、通过未为终端进行资源分配的设备,获取当前的信道统计信息。
需要说明的是,终端可能在某种情况下,会与某基站连接,但是,该基站不会为终端发送分配资源的信息。该基站可能会实现测量信道信息,得到信道统计信息的功能,此时终端只需从基站侧获取到该信道统计信息即可,无需再自行进行测量,减少了终端侧的测量时间。
在实际应用中,根据信道占用信息的不同,步骤23又有不同的实现方式,下面分别针对信道占用信息为信道占空比和信道占用信息为信道占用功率测量值小于或等于预设值的资源比重时,步骤23的实现进行具体说明。
1、当信道占用信息为信道占空比时,步骤23的第一种实现方式为:
根据预设的信道占空比与预设的资源大小的对应关系,确定用于传输数据的资源信息。
此种方式,通常是在终端中预设有信道占空比与资源大小的对应关系表,该对应关系表中包括多个信道占空比以及每个信道占空比对应的资源大小,终端只需根据对应关系表找到当前得到的信道占空比对应的资源大小即可。
通常情况下,该实现方式中,可以确定用于传输数据的时频资源,即终端具体在哪些时频资源上进行数据的传输,具体地,终端会在所有或部分空闲资源中,确定用于传输数据的时频资源,此处在确定时频资源时,可以是 随机在所有或部分空闲资源中确定,也可以是终端按照预设的规则(条件)进行确定。
在实际应用中,针对应用该实现方式的数据传输方法举例说明如下:
该数据传输方法包括:
步骤a1:终端通过底层测量感知得到信道占空比;
需要说明的是,该信道占空比可以是实际的比例,例如10%,也可以是相对的等级,例如当信道占空比为75%至100%是为高级,信道占空比为25%至74%为中级,信道占空比为0%至24%为低级。
步骤a2:终端根据预定义的信道占空比与资源大小的对应关系确定可预约的资源大小(即用于传输数据的资源大小);
需要说明的是,上述所说的可预约的资源大小可以是一段时间内终端可预约的总资源大小,也可以是单个子帧可预约的资源大小。
例如,信道占空比为10%时对应的可预约资源大小为500Bytes,信道占空比为高级时对应的可预约资源大小为10Bytes。
步骤a3:终端将得到的可预约的资源大小上报给终端的高层;
需要说明的是,这里所说的高层为终端的物理层之上的层,例如可以是终端的MAC层或者是为不低于终端的RLC层的层。
步骤a4:高层收到可预约的资源大小,并据此对数据包进行分段等操作。
步骤a5:终端按照可预约资源大小选择时频资源。
步骤a6:高层业务数据包在终端选择的时频资源上传输。
2、当信道占用信息为信道占空比时,步骤23的第二种实现方式为:
根据所述信道占空比,并结合终端的高层的应用需求信息,确定用于传输数据的资源信息。
需要说明的是,该实现方式中,终端的高层可能会提前设定了发送数据包所用的资源的大小,此时,可以依据得到的信道占空比,在考虑终端的高层的应用需求的前提下,进行资源大小的确定。
通常情况下,该实现方式中,终端可以确定用于传输数据的时频资源,即具体的在哪些时频资源上进行数据的传输,具体地,终端会在所有或部分空闲资源中,确定用于传输数据的时频资源。
在实际应用中,针对应用该实现方式的数据传输方法举例说明如下:
该数据传输方法包括:
步骤b1:终端通过底层测量感知得到信道占空比;
需要说明的是,这个信道占空比可以是实际的比例,例如10%,也可以是相对的等级,例如高级。
步骤b2:终端根据实际的高层应用需求与感知到的信道占空比,确定自己可用的资源大小;
例如,信道占空比为10%,说明目前可用资源比较充足,可选择满足高层应用传输需求的资源大小;信道占空比为高级,说明目前可用资源比较紧张,可能需要进行拥塞控制,可选择仅满足部分高优先级应用传输需求的资源大小。
步骤b3:终端将得到的可预约的资源大小上报给高层。
步骤b4:高层收到可预约的资源大小,并据此对数据包进行分段等操作。
步骤b5:终端按照可预约资源大小选择时频资源。
步骤b6:高层业务数据包在终端选择的时频资上源传输。
3、当信道占用信息为信道占用功率测量值小于或等于预设值的资源比重时,步骤23的第一种实现方式为:
根据预设的信道占用功率测量值小于或等于预设值的资源比重与预设的资源大小的对应关系,确定用于传输数据的资源信息。
此种方式,通常是在终端中预设有信道占用功率测量值小于或等于预设值的资源比重与资源大小的对应关系表,该对应关系表中包含多个信道占用功率测量值小于或等于预设值的资源比重以及每个信道占用功率测量值小于或等于预设值的资源比重对应的资源大小,终端只需根据列表找到当前得到的信道占用功率测量值小于或等于预设值的资源比重对应的资源大小即可。
通常情况下,该实现方式中,可以确定用于传输数据的时频资源,即终端具体在哪些时频资源上进行数据的传输,具体地,终端会在所有或部分信道占用功率测量值小于或等于预设值的资源中,确定用于传输数据的时频资源,此处在确定时频资源时,可以是随机在所有或部分信道占用功率测量值小于或等于预设值的资源中确定,也可以是终端按照预设的规则(条件)进 行确定。
在实际应用中,针对应用该实现方式的数据传输方法举例说明如下:
该数据传输方法包括:
步骤c1:终端通过底层测量感知得到信道占用功率测量值低于给定阈值的资源比重;
需要说明的是,该资源比重可以是实际的比例,例如10%,也可以是相对的等级,例如当资源比重为75%至100%是为高级,资源比重为25%至74%为中级,资源比重为0%至24%为低级。
步骤c2:终端根据预定义的资源比重与资源大小的对应关系确定可预约的资源大小;
例如,资源比重为10%时对应的可预约资源大小为500Bytes,资源比重为高级时对应的可预约资源大小为10Bytes。
步骤c3:终端将得到的可预约的资源大小上报给高层;
步骤c4:高层收到可预约的资源大小,并据此对数据包进行分段等操作;
步骤c5:终端按照可预约资源大小选择时频资源;
步骤c6:高层业务数据包在终端选择的时频资源上传输。
4、当信道占用信息为信道占用功率测量值小于或等于预设值的资源比重时,步骤23的第二种实现方式为:
根据所述信道占用功率测量值小于或等于预设值的资源比重,并结合终端的高层的应用需求信息,确定用于传输数据的资源信息。
需要说明的是,该实现方式中,终端的高层可能会提前设定了发送数据包所用的资源的大小,此时,可以依据得到的信道占用功率测量值小于或等于预设值的资源比重,在满足终端的高层的应用需求的前提下,进行资源大小的确定。
通常情况下,该实现方式中,终端可以确定用于传输数据的时频资源,即具体的在哪些时频资源上进行数据的传输,具体地,终端会在所有或部分信道占用功率测量值小于或等于预设值的资源中,确定用于传输数据的时频资源。
在实际应用中,针对应用该实现方式的数据传输方法举例说明如下:
该数据传输方法包括:
步骤d1:终端通过底层测量感知得到信道占用功率测量值低于给定阈值的资源比重;
需要说明的而是,该资源比重可以是实际的比例,例如10%,也可以是相对的等级,例如高级。
步骤d2:终端根据实际的高层应用需求与感知到的资源比重,确定自己可用的资源大小;
例如,资源比重为10%,说明目前可用资源比较充足,可选择满足高层应用传输需求的资源大小,资源比重为高级,说明目前可用资源比较紧张,可能需要进行拥塞控制,可选择仅满足传输高优先级业务的资源大小。
步骤d3:终端将得到的可预约的资源大小上报给高层;
步骤d4:高层收到可预约的资源大小,并据此对数据包进行分段等操作;
步骤d5:终端按照可预约资源大小选择时频资源;
步骤d6:高层业务数据包在终端选择的时频资源上传输。
需要说明的是,上述各种实现方式中,因终端的数据包最终是通过物理层传递给外部设备的,通常情况下,终端的底层将得到的资源信息传递给终端的高层,然后由高层根据该资源信息进行数据包的分段,在分段完成后,将封装的数据传递给终端的物理层,然后由终端的物理层将高层传递的数据在已确定的资源上进行发送。
本公开文本实施例,通过利用网络的实时信道统计信息,进行资源信息的确定,保证了终端每次确定的资源信息都是与网络实时状态相匹配的,保证了终端通信的可靠与安全。
在本公开文本一些实施例中,如图3所示,提供一种数据传输方法,应用于终端侧,包括:
步骤31,在未为终端进行资源分配的设备中,获取当前的信道占用信息;
需要说明的是,终端可能在某种情况下,会与某基站连接,但是,该基站不会为终端发送分配资源的信息,此时,还是需要终端自己确定发送数据的资源信息,但是,基站可能会将实时的网络状态信息发送给终端,此时终端在基站发送的网络状态信息中获取到当前的信道占用信息。
步骤32,根据所述信道占用信息,确定用于传输数据的资源信息;
该步骤中,通过信道占用信息,并可以确定处终端用于传输数据的资源信息,其中,该资源信息主要指的是资源的大小。
步骤33,根据所述资源信息,进行数据的传输。
需要说明的是,在进行通信数据的传输前,通常是由终端的高层利用该资源信息,对将要传输的数据包进行分段,以使得数据适于在该资源上传输。
通常情况下,该数据传输方法在终端的底层实现,该底层可以是终端在逻辑上划分的物理层,也可以是MAC层。
需要说明的是,本公开文本实施例中,终端从基站侧直接获取当前的信道占用信息,无需自己根据信道统计信息计算得到当前的信道占用信息,此种方式,减少了终端内部的信令传递,降低了终端的功耗。
