Abstract

Description

一种缓存状态上报方法、终端和计算机存储介质 技术领域
本发明涉及无线通信技术，具体涉及一种缓存状态上报方法、终端和计算机存储介质。
背景技术
终端通过上报缓存状态报告(BSR，Buffer Status Report)的形式告知基站自身缓存的待传输数据状态，以便基站能够更准确的给终端分配无线资源。根据触发BSR事件的不同，BSR可分为常规BSR(Regular BSR)、填充BSR(Padding BSR)和周期BSR(Periodic BSR)。根据BSR的格式，BSR可分为短BSR(short BSR)、长BSR(long BSR)和截短BSR(truncated BSR)。其中，Padding BSR的承载方式是承载在媒体接入控制层协议数据单元(MAC PDU，Media Access Control Protocol Data Unit)的填充比特(padding bit)内。
当终端触发的BSR类型是Padding BSR，且有多个逻辑信道有数据传输，且填充比特长度大于等于一个short BSR及其对应的媒体接入控制(MAC，Media Access Control)子包头，但不足以用来发送long BSR及其对应的MAC子包头时，终端采用truncated BSR类型上报BSR。
但是，truncated BSR采用1字节(byte)的格式，这种格式的truncated BSR仅能上报多个逻辑信道组中的一个逻辑信道组对应的缓存数据状态，而无法上报有数据传输的多个逻辑信道组对应的缓存数据状态，使得基站无法获知所有有数据传输的逻辑信道组对应的缓存数据状态，从而也无法准确的给终端分配无线资源。
发明内容

在一实施例中，所述终端根据填充比特大小、第一类型BSR格式的大小和对应的MAC子包头大小之和、以及当前有缓存待传数据的逻辑信道组数量，确定上报的BSR格式，包括：

具体实施方式
下面结合附图及具体实施例对本发明作进一步详细的说明。
实施例一
本发明实施例提供了一种缓存状态上报方法。图1为本发明实施例的缓存状态上报方法的一种流程示意图；如图1所示，所述方法包括：
步骤101：终端触发填充缓存状态报告(padding BSR)上报。
步骤102：所述终端根据填充比特大小、第一类型BSR格式的大小和对应的MAC子包头大小之和、以及当前有缓存待传数据的逻辑信道组数 量，确定上报的BSR格式；所述BSR格式对应的逻辑信道组数量大于等于1，小于等于当前有缓存待传数据的逻辑信道组的最大数量。
本实施例中，padding BSR的触发条件包括：已分配的上行资源中用于填充的比特长度大于或等于BSR的媒体接入控制层控制元(MAC CE，Media Access Control Control Element)和相应的MAC子包头(subheader)长度之和，则触发padding BSR上报。其中，padding BSR承载在MAC PDU的填充比特(padding bit)内，封装为MAC CE。
本实施例中，所述终端具体根据填充比特大小、第一类型BSR格式的大小和对应的MAC子包头大小之和、以及当前有缓存待传数据的逻辑信道组数量，确定上报的BSR格式；其中，第一类型BSR具体可以为short BSR。图2a至图2c分别为本发明实施例的缓存状态上报方法中的BSR格式的示意图；如图2a所示，为short BSR格式示意图，包括1字节(byte)的MAC子包头和1字节的short BSR；其中，MAC子包头中包括逻辑信道标识(LCID)，该LCID指示对应的MAC CE类型，即LCID指示上报的BSR格式类型；short BSR包括当前有缓存待传数据的仅有的一个逻辑信道组标识(LCG ID)，以及通过缓存尺寸(BS，Buffer Size)表示所述逻辑信道组的的缓存状态信息的大小。
作为第一种实施方式，所述终端根据填充比特大小、第一类型BSR格式的大小和对应的MAC子包头大小之和、以及当前有缓存待传数据的逻辑信道组数量，确定上报的BSR格式，包括：
当所述填充比特大小大于所述第一类型BSR格式的大小和对应的MAC子包头大小之和、小于第二类型BSR格式的最大长度和对应的MAC子包头大小之和、且当前有缓存待传数据的逻辑信道组数量为至少两个时，基于当前有缓存待传数据的逻辑信道组对应的第二类型BSR格式的大小和对应的MAC子包头大小之和以及所述填充比特大小确定上报的BSR格式。
其中，所述基于当前有缓存待传数据的逻辑信道组对应的第二类型BSR格式的大小和对应的MAC子包头大小之和以及所述填充比特大小确定上报的BSR格式，包括：若当前有缓存待传数据的逻辑信道组对应的第二类型BSR格式的大小和对应的MAC子包头大小之和小于等于所述填充比特，确定上报第二类型BSR格式，所述第二类型BSR格式对应的逻辑信道组数量等于当前有缓存待传数据的逻辑信道组的数量。
其中，所述基于当前有缓存待传数据的逻辑信道组对应的第二类型BSR格式的大小和对应的MAC子包头大小之和以及所述填充比特大小确定上报的BSR格式，包括：若当前有缓存待传数据的逻辑信道组对应的第二类型BSR格式的大小和对应的MAC子包头大小之和大于所述填充比特，确定上报第三类型BSR格式，所述第三类型BSR格式对应的逻辑信道组数量大于1，小于当前有缓存待传数据的逻辑信道组的数量。
具体的，本实施方式中，比较填充比特大小和所述第一类型BSR格式的大小和对应的MAC子包头大小之和，以及比较填充比特和第二类型BSR格式的最大长度和对应的MAC子包头大小之和；其中，所述第一类型BSR格式可参照图2a所示，则所述第一类型BSR格式的大小和对应的MAC子包头大小之和为2字节。本实施例中，所述第二类型BSR具体为灵活长BSR(flexible long BSR)，flexible long BSR格式具体可参照图2b或图2c所示；在5G系统中，上报BSR可以配置的逻辑信道组的数量最大为8个，即BSR格式中最大可包括8个逻辑信道组的缓存状态信息。如图2b所示，为flexible long BSR的一种格式示意，包括：比特图(该比特图记为第一比特图)，所述第一比特图中的比特位对应于当前有缓存待传数据的逻辑信道组；还包括所述当前有缓存待传数据的逻辑信道组中每个逻辑信道组的缓存状态信息；每个逻辑信道组的缓存状态信息按照对应于所述第一比特图中的排序依次排列；还包括1字节的MAC子包头，MAC子包头中包括LCID，该 LCID指示对应的MAC CE类型，即LCID指示上报的BSR格式类型。具体的，第一比特图中的比特位为1或0用于表示该比特位对应的LCG的缓存状态信息是否包含在该flexible long BSR内；若某比特位为1，则表示该比特位对应的LCG的缓存状态信息包含在该flexible long BSR内，若某比特位为0，则表示该比特位对应的LCG的缓存状态信息未包含在该flexible long BSR内，即不存在该比特位对应的LCG的缓存状态信息。其中，逻辑信道组的缓存状态信息的大小可如图2b中所示的6比特，当前不限于6比特长度，还以可以是大于6比特长度。则flexible long BSR的最大长度依据逻辑信道组的缓存状态信息的大小会有变化；当逻辑信道组的缓存状态信息的大小如图2b中所示的6比特时，flexible long BSR的最大长度和对应的MAC子包头大小之和为8字节。
如图2c所示，为flexible long BSR的另一种格式示意，包括所有当前有缓存待传数据的逻辑信道组的标识以及对应的缓存状态信息；每个逻辑信道组的缓存状态信息按照对应的标识顺序依次排列；还包括2字节的MAC子包头，MAC子包头中包括LCID和BSR长度信息，flexible long BSR长度信息可通过MAC子包头中的“L”指示。其中，逻辑信道组标识的长度可如图2c所示的3比特；逻辑信道组的缓存状态信息的大小可如图2c中所示的6比特，当前不限于6比特长度，还以可以是大于6比特长度。则flexible long BSR的最大长度依据逻辑信道组的缓存状态信息的大小会有变化；当逻辑信道组的缓存状态信息的大小如图2c中所示的6比特时，flexible long BSR的最大长度和对应的MAC子包头大小之和为11字节。
基于此，本实施方式中，当填充比特大小大于2字节但小于flexible long BSR的最大长度和对应的MAC子包头大小之和，并且当前有缓存待传数据的逻辑信道组数量为至少两个时，若当前有缓存待传数据的逻辑信道组对应的flexible long BSR格式的大小和对应的MAC子包头大小之和小于等 于所述填充比特，确定上报flexible long BSR格式；若当前有缓存待传数据的逻辑信道组对应的flexible long BSR格式的大小和对应的MAC子包头大小之和大于所述填充比特大小，确定上报第三类型BSR格式，所述第三类型BSR格式对应的逻辑信道组数量大于1，小于当前有缓存待传数据的逻辑信道组的数量。
这里，所述第三类型BSR具体可以为灵活截短BSR(flexible truncated BSR)；flexible truncated BSR格式具体可也参照图2b和图2c所示，区别在于，对于具有相同格式的flexible truncated BSR和flexible long BSR，对应子包头中的LCID不同。如图2b所示，为flexible truncated BSR的一种格式示意，包括：比特图(该比特图记为第二比特图)，还包括当前有缓存待传数据的部分逻辑信道组中每个逻辑信道组的缓存状态信息；所述部分逻辑信道组中每个逻辑信道组的缓存状态信息按照所述部分逻辑信道组对应于所述第二比特图中的排序依次排列。还包括1字节的MAC子包头，MAC子包头中包括LCID。该LCID指示对应的MAC CE类型，即LCID指示上报的BSR格式类型。第二比特图中的比特位为1或0用于表示该比特位对应的LCG的缓存状态信息是否包含在该flexible truncated BSR内；若某比特位为1，则表示该比特位对应的LCG的缓存状态信息包含在该flexible truncated BSR内，若某比特位为0，则表示该比特位对应的LCG的缓存状态信息未包含在该flexible truncated BSR内，即不存在该比特位对应的LCG的缓存状态信息。其中，逻辑信道组的缓存状态信息的大小可如图2b中所示的6比特，当前不限于6比特长度，还以可以是大于6比特长度。则flexible truncated BSR的最大长度依据逻辑信道组的缓存状态信息的大小会有变化；当逻辑信道组的缓存状态信息的大小如图2b中所示的6比特时，flexible truncated BSR的最大长度和对应的MAC子包头大小之和为8字节。
如图2c所示，可作为flexible truncated BSR的另一种格式示意，包括 所有当前有缓存待传数据的逻辑信道组中的部分逻辑信道组的标识以及对应的缓存状态信息；部分逻辑信道组的缓存状态信息按照部分逻辑信道组标识的顺序依次排列；还包括2字节的MAC子包头，MAC子包头中包括LCID和BSR长度信息，flexible truncated BSR长度信息可通过MAC子包头中的“L”指示。其中，逻辑信道组标识的长度可如图2c所示的3比特；逻辑信道组的缓存状态信息的大小可如图2c中所示的6比特，当前不限于6比特长度，还以可以是大于6比特长度。则flexible truncated BSR的最大长度依据逻辑信道组的缓存状态信息的大小会有变化；当逻辑信道组的缓存状态信息的大小如图2c中所示的6比特时，flexible truncated BSR的最大长度和对应的MAC子包头大小之和为11字节。
这里，所述确定上报第三类型BSR格式之前，所述方法还包括：将所述当前有缓存待传数据的逻辑信道组按照优先级排序；按照优先级排序结果在所述当前有缓存待传数据的逻辑信道组中选择满足所述填充比特的部分逻辑信道组。其中，逻辑信道组的优先级具体可以是该逻辑信道组中一逻辑信道的优先级；作为一种实施方式，可将逻辑信道组中包括的逻辑信道的最大的优先级作为该逻辑信道组的优先级。实际应用中，将所述当前有缓存待传数据的逻辑信道组按照优先级由高到低进行排序；基于所述填充比特的大小从高到低选择所述当前有缓存待传数据的逻辑信道组中的部分逻辑信道组，因为填充比特大小无法满足所有当前有缓存待传数据的逻辑信道组。
基于此，虽然第二类型BSR格式(flexible long BSR)和第三类型BSR格式(flexible truncated BSR)可具有相同的格式，但第二类型BSR中包括所有当前有缓存待传数据的逻辑信道组的缓存状态信息，而第三类型BSR中仅包括当前有缓存待传数据的逻辑信道组中的部分逻辑信道组的缓存状态信息。
作为第二种实施方式，所述终端根据填充比特大小、第一类型BSR格式的大小和对应的MAC子包头大小之和、以及当前有缓存待传数据的逻辑信道组数量，确定上报的BSR格式，包括：当所述填充比特大小大于所述第一类型BSR格式的大小和对应的MAC子包头大小之和、小于第二类型BSR格式的最大长度和对应的MAC子包头大小之和、且当前有缓存待传数据的逻辑信道组数量为一个时，确定上报所述第一类型BSR格式。
具体的，本实施方式中，当填充比特大小大于2字节但小于flexible long BSR的最大长度和对应的MAC子包头大小之和，并且当前有缓存待传数据的逻辑信道组数量为至少两个时，确定上报short BSR格式，即通过图2a所示的格式上报当前仅有的一个有缓存待传数据的逻辑信道组的缓存状态信息，其中，上报的short BSR格式中的MAC子包头中的LCID指示对应的MAC CE类型，即LCID指示上报的BSR格式类型。
作为第三种实施方式，所述终端根据填充比特大小、第一类型BSR格式的大小和对应的MAC子包头大小之和、以及当前有缓存待传数据的逻辑信道组数量，确定上报的BSR格式，包括：当所述填充比特大小大于第二类型BSR格式的最大长度和对应的MAC子包头大小之和时，确定上报第二类型BSR格式，所述第二类型BSR格式对应的逻辑信道组数量等于当前有缓存待传数据的逻辑信道组的数量。
具体的，本实施方式中，当填充比特大小大于flexible long BSR的最大长度和对应的MAC子包头大小之和时，确定上报flexible long BSR格式，所述flexible long BSR格式包括所有当前有缓存待传数据的逻辑信道组的标识以及对应的缓存状态信息。
作为第四种实施方式，所述终端根据填充比特大小、第一类型BSR格式的大小和对应的MAC子包头大小之和、以及当前有缓存待传数据的逻辑信道组数量，确定上报的BSR格式，包括：当所述填充比特大小等于所述 第一类型BSR格式的大小和对应的MAC子包头大小之和、且当前有缓存待传数据的逻辑信道组数量为至少两个时，确定上报第四类型BSR格式，所述第四类型BSR格式对应至少两个逻辑信道组中的一个逻辑信道组。
具体的，本实施方式中，当填充比特大小等于所述第一类型BSR格式的大小和对应的MAC子包头大小之和(即2字节)，并且当前有缓存待传数据的逻辑信道组数量为至少两个时，确定上报第四类型BSR格式，所述第四类型BSR格式具体可以为truncated BSR格式，truncated BSR格式可参照图2a所示的格式，包括1字节的MAC子包头和1字节的truncated BSR，其中，MAC子包头中的LCID指示对应的MAC CE类型，即LCID指示上报的BSR格式类型；truncated BSR包括当前有缓存待传数据的至少两个逻辑信道组的其中一个逻辑信道组的标识(LCG ID)，以及通过缓存尺寸表示该逻辑信道组的的缓存状态信息的大小。
作为第五种实施方式，所述终端根据填充比特大小、第一类型BSR格式的大小和对应的MAC子包头大小之和、以及当前有缓存待传数据的逻辑信道组数量，确定上报的BSR格式，包括：当所述填充比特大小等于所述第一类型BSR格式的大小和对应的MAC子包头大小之和、且当前有缓存待传数据的逻辑信道组数量为一个时，确定上报所述第一类型BSR格式，所述第一类型BSR格式对应所述逻辑信道组。
具体的，本实施方式中，当填充比特大小大于等于所述第一类型BSR格式的大小和对应的MAC子包头大小之和(即2字节)，并且当前有缓存待传数据的逻辑信道组数量为一个时，确定上报所述第一类型BSR格式，即上报short BSR格式。
图3为本发明实施例的缓存状态上报方法的另一种流程示意图；如图3所示，以第一类型BSR为short BSR、第二类型BSR为flexible long BSR、第三类型BSR为flexible truncated BSR、第四类型BSR为truncated BSR为 例对本发明实施例的缓存状态上报方法进行说明。上述缓存状态上报方法可通过以下流程实现：
步骤201：终端触发padding BSR上报。
步骤202：所述终端判断填充比特大小是否大于short BSR格式的大小和对应的MAC子包头大小之和、小于flexible long BSR格式的最大长度和对应的MAC子包头大小之和；当判断结果为填充比特大小大于short BSR格式的大小和对应的MAC子包头大小之和、小于flexible long BSR格式的最大长度和对应的MAC子包头大小之和时，执行步骤203；当判断结果为填充比特大小小于等于short BSR格式的大小和对应的MAC子包头大小之和时，执行步骤208；当判断结果为填充比特大小大于所述flexible long BSR格式的最大长度和对应的MAC子包头大小之和时，执行步骤206。
步骤203：判断当前有缓存待传数据的逻辑信道组数量是否大于1；当判断结果为当前有缓存待传数据的逻辑信道组数量大于1时，执行步骤204至步骤206；当判断结果为当前有缓存待传数据的逻辑信道组数量等于1时，执行步骤207。
步骤204：判断当前有缓存待传数据的逻辑信道组对应的flexible long BSR格式的大小和对应的MAC子包头大小是否大于所述填充比特大小；当判断结果为当前有缓存待传数据的逻辑信道组对应的flexible long BSR格式的大小和对应的MAC子包头大小大于所述填充比特大小，执行步骤205；当判断结果为当前有缓存待传数据的逻辑信道组对应的flexible long BSR格式的大小和对应的MAC子包头大小小于等于所述填充比特大小，执行步骤206。

步骤209：确定上报truncated BSR格式。
采用本发明实施例的技术方案，通过上报的BSR格式可对应大于等于1、小于等于当前有缓存待传数据的逻辑信道组的最大数量的逻辑信道组，实现了尽可能多的上报当前有缓存待传数据的逻辑信道组的缓存状态信息，从而使基站能够更多的获知终端当前有缓存待传数据的逻辑信道组的缓存情况，大大实现了为终端分配无线资源的准确率。
