需要说明的是，在本文中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者装置不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者装置所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的过程、方法、物品或者装置中还存在另外的相同要素，此外，本申请不同实施例中具有同样命名的部件、特征、要素可能具有相同含义，也可能具有不同含义，其具体含义需以其在该具体实施例中的解释或者进一步结合该具体实施例中上下文进行确定。
应当理解，尽管在本文可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本文范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，如在此所使用的词语"如果"可以被解释成为"在……时"或"当……时"或"响应于确定"。再者，如同在本文中所使用的，单数形式“一”、“一个”和“该”旨在也包括复数形式，除非上下文中有相反的指示。应当进一步理解，术语“包含”、“包括”表明存在所述的特征、步骤、操作、元件、组件、项目、种类、和/或组，但不排除一个或多个其他特征、步骤、操作、元件、组件、项目、种类、和/或组的存在、出现或添加。本申请使用的术语“或”、“和/或”、“包括以下至少一个”等可被解释为包括性的，或意味着任一个或任何组合。例如，“包括以下至少一个：A、B、C”意味着“以下任一个：A；B；C；A和B；A和C；B和C；A和 B和C”，再如，“A、B或C”或者“A、B和/或C”意味着“以下任一个：A；B；C；A和B；A和C；B和C；A和B和C”。仅当元件、功能、步骤或操作的组合在某些方式下内在地互相排斥时，才会出现该定义的例外。

需要说明的是，在本文中，采用了诸如S1、S2等步骤代号，其目的是为了更清楚简要地表述相应内容，不构成顺序上的实质性限制，本领域技术人员在具体实施时，可能会先执行S2后执行S1等，但这些均应在本申请的保护范围之内。
应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。

虽然上述以LTE系统为例进行了介绍，但本领域技术人员应当知晓，本申请不仅仅适用于LTE系统，也可以适用于其他无线通信系统，例如GSM、CDMA2000、WCDMA、TD-SCDMA以及未来新的网络系统(如5G)等，此处不做限定。
基于上述移动终端硬件结构以及通信网络系统，提出本申请各个实施例。
5G三大应用场景包括增强型移动宽带(eMBB)、海量机器类通信(mMTC)和超高可靠低时延通信(uRLLC)。在eMBB、uRLLC等应用场景之外，工业无线传感器、视频监控和可穿戴设备等中端物联网用例对5G终端提出了复杂度与成本降低、尺寸减小、能耗更低等要求。为此，提出了终端设备的新的设备类型，即低复杂度低成本终端设备或轻型能力设备(即RedCap UE)，以更好地满足这些用例的需求。
终端设备可以包括轻型能力设备和普通设备，其中轻型能力设备例如可以包括冰箱、电视、空调等家用电器，例如可以包括智能手表、运动手环等穿戴设备等，例如：智能电网、智能电表等智能工业设备，还包括低功耗/低复杂度/低成本/低性能的智能手机以及一些功能手机，其中普通设备例如可以包括智能手机，智能汽车等。轻型能力设备与普通设备的差别并不限于设备类型的差异，例如可以将处于低功耗或者低性能的状态下普通设备也可以作为轻型能力设备，差异主要在于设备当前的带宽、数据速率等。
在介绍终端设备的不同设备类型的基础上，对终端设备的缓冲区进行介绍。
一些实现中，在业务数据的传输或处理过程中，终端设备会预留MAC层的缓冲区或物理层的缓冲区，用于存储在HARQ时的业务数据。可选地，终端设备的缓冲区包括层1缓冲区和层2缓冲区，层1缓冲区的大小与最大传输块大小成正相关关系，层2缓冲区的大小与数据速率的大小成正相关关系。
由于终端设备包括普通设备和轻型能力设备这两种不同的设备类型的设备，针对普通设备而言，普通设备传输业务数据的数据速率较大，因此普通设备的缓冲区也较大。而针对轻型能力设备而言，由于轻型能力设备传输业务数据的数据速率较小，若采用和普通设备相同大小的缓冲区，会造成轻型能力设备的硬件资源浪费。基于此，本申请提供一种处理方法，以确定轻型能力设备的缓冲区大小，减小硬件资源浪费。
图3为本申请实施例提供的处理方法的信令图一，如图3所示，该方法可以应用于终端设备，具体包括以下步骤：
S31，网络设备向终端设备发送业务数据的缓存信息。
网络设备可以是用于与终端设备进行通信的设备，例如，可以是全球移动通信系统(Global System for Mobile Communication，GSM)或码分多址(Code Division Multiple Access，CDMA)通信系统中的基站(Base Transceiver Station，BTS)，也可以是宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统中的基站(NodeB，NB)，还可以是LTE系统中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络或5G之后的网络中的网络侧设备或未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)网络中的网络设备等。
本申请实施例中涉及的网络设备也可称为无线接入网(Radio Access Network，RAN)设备。RAN设备与终端设备连接，用于接收终端设备的数据并发送给核心网设备。RAN设备在不同通信系统中对应不同的设备，例如，在2G系统中对应基站与基站控制器，在3G系统中对应基站与无线网络控制器(Radio Network Controller，RNC)，在4G系统中对应演进型基站(Evolutional Node B，eNB)，在5G系统中对应5G系统，如新无线(New Radio，NR)中的接入网设备(例如gNB，集中单元CU，分布式单元DU)。
网络设备可以向终端设备发送业务数据的缓存信息，通过缓存信息指示第一最大传输块大小。
S32，终端设备根据业务数据的缓存信息确定第一最大传输块大小，第一最大传输块大小小于或等于第一设备类型对应的第二最大传输块大小。
本申请实施例中的终端设备可以是普通设备，也可以是轻型能力设备。
可选地，本申请实施例中的终端设备为轻型能力设备，第一设备类型的设备为普通设备。根据业务数据的缓存信息可以确定终端设备的第一最大传输块大小，第一最大传输块大小小于或等于第一设备类型对应的第二最大传输块大小，即第一最大传输块大小小于或等于普通设备对应的第二最大传输块大小。
S33，终端设备根据第一最大传输块大小确定业务数据的缓冲区大小。
可选地，业务数据的缓冲区大小包括层1缓冲区大小和/或层2缓冲区大小，层1缓冲区大小与终端设备的最大传输块大小成正相关。本申请实施例中，终端设备的第一最大传输块大小小于或等于第一设备类型对应的最大传输块大小，因此终端设备的层1缓冲区大小小于或等于第一设备类型对应的层1缓冲区大小，进而终端设备的业务数据的缓冲区大小小于或等于第一设备类型对应的业务数据的缓冲区大小。
本申请实施例提供的处理方法，首先根据业务数据的缓存信息确定第一最大传输块大小，然后根据第一最大传输块大小确定业务数据的缓冲区大小。针对于轻型设备这类终端设备而言，由于其第一最大传输块大小小于或等于第一设备类型对应的最大传输块大小，而最大传输块大小又与终端设备的缓冲区大小成正相关关系，因此轻型设备设置的缓冲区大小小于或等于第一设备类型的终端设备(即普通终端设备)的缓冲区大小，即通过限制轻型设备的缓冲区大小可以减少硬件资源浪费。
在上述实施例中介绍了通过设置第一最大传输块，且第一最大传输块大小小于或等于第一设备类型对应的最大传输块大小，从而通过减小最大传输块大小进而减小终端设备的缓冲区的方案，下面将结合具体的实施例对确定第一最大传输块大小的方案进行详细介绍。
首先介绍终端设备的最大传输块大小的计算过程。
设分配给物理下行链路共享信道(Physical Downlink Shared Channel，PDSCH)的每个PRB的可用资源元素(resource element，RE)的数量为N'RE，N'RE的计算公式如下式(1)示意：
其中，为一个时隙内的PDSCH分配的符号数目，为每个物理资源块(Physical Resource Block，PRB)中解调参考信号(demodulation reference signal，DMRS)所占的RE数目，为无线资源开销参数，由PDSCH-ServingCellConfig内的高层参数xOverhead配置，当配置了时，取值为6,12,18中的任一项，和/或，当未配置时，取值为0，即
在根据式(1)确定了N'RE后，可以根据下式(2)获取可用PRB对应的总的可用RE数NRE：
NRE＝min(156,N'RE)*nPRB                      (2)
可选地，根据NRE可以得到中间变量Ninfo：
Ninfo＝NRE*R*Qm*v                      (3)
其中，R为根据调制与编码策略(Modulation and Coding Scheme，MCS)索引确定的码率，Qm为根据MCS索引确定的调制策略参数。
在上述实施例中介绍了获取中间变量Ninfo的方案，根据Ninfo可以获取N'info，其中：
在Ninfo≤3824时，
在式(4)中，
在Ninfo>3824时，
在式(5)中，
在得到N'info后，可以根据N'info计算得到最大传输块大小TBS。具体的：
在码率R≤1/4时，可以得到最大传输块TBS为：
在码率R>1/4时，可以得到最大传输块TBS为：

结合式(1)至式(8)可得最大传输块的大小，进而根据最大传输块大小确定层1缓冲区大小。可选地，上述计算最大传输块大小的方案，适用于第一设备类型的终端设备，即普通设备，也适用于第二设备类型的终端设备，即轻型能力设备。
式(6)至式(8)示例了在不同的码率R以及N'info的不同取值下计算最大传输块TBS的方式。根据式(6)至式(8)可知，TBS与N'info是正相关的，即N'info越大，则TBS越大，反 之N'info越小，则TBS越小。
式(4)和式(5)示例了在Ninfo的不同取值范围下计算N'info的方式，根据式(4)和式(5)可知，N'info与Ninfo也是正相关的，即Ninfo越大，则N'info越大，反之Ninfo越小，则N'info越小。
式(3)至(8)示例了TBS的大小与NRE、R、Qm等相关，综上所述可知，可以通过减小NRE、R、Qm的值减小TBS，进而达到减小终端设备的缓冲区大小的目的，也可以通过修改式(3)中Ninfo的计算公式来减小TBS，进而减小终端设备的缓冲区大小的目的。
本申请实施例中，根据业务数据的缓存信息可以确定第一最大传输块大小，可选地，缓存信息包括第一无线资源开销参数、第一频域映射参数、第一调制与编码方式参数、第一比例因子中的至少一项。可选地，通过第一无线资源开销参数和/或第一频域映射参数可以减小NRE的值，通过第一调制与编码方式参数可以减小R和Qm的值，通过第一比例因子可以在式(3)的基础上修改Ninfo的计算公式来减小Ninfo，从而减小TBS。即，通过缓存信息中的各项参数能够达到减小TBS进而减小终端设备的缓冲区大小的目的。下面将对缓存信息中的各项参数分别进行介绍。
可选地，根据第一无线资源开销参数和/或第一频域映射参数，可以确定PDSCH的每个PRB中可用资源单元数目，然后根据可用资源单元数目、第一调制与编码方式参数和第一比例因子中的至少一项，确定第一最大传输块大小。
可选地，缓存信息中包括第一无线资源开销参数，第一无线资源开销参数为新定义的RRC参数xOverhead-redcap，用于指示终端设备PDSCH可用PRB上的其他资源的预留开销。
可选地，第一无线资源开销参数为轻型设备的无线资源开销参数。
可选地，第一无线资源开销参数大于或等于第一设备类型的无线资源开销参数。
根据式(1)可知，根据无线资源开销参数可以获取分配给PDSCH的每个PRB的可用RE的数量N'RE。设第一无线资源开销参数为第一设备类型的第二无线资源开销参数为则可以分别得到分配给PDSCH的每个PRB的可用RE的数量如下：

其中，N'RE1为轻型能力设备对应的分配给PDSCH的每个PRB的可用RE的数量，N'RE2为普通设备对应的分配给PDSCH的每个PRB的可用RE的数量。由于因此N'RE1≤N'RE2，即相比于第一设备类型的终端设备而言，本申请实施例中通过增大无线资源开销参数的取值来减小分配给PDSCH的每个PRB的可用RE的数量。根据式(2)至式(7)可知，分配给PDSCH的每个PRB的可用RE的数量N'RE与TBS成正相关关系。因此通过减小分配给PDSCH的每个PRB的可用RE的数量也可以减小TBS。即本申请中轻型能力设备的TBS小于或等于第一设备类型对应的TBS。
可选地，第一无线资源开销参数取值包括以下至少一项：0、6、12、18、30，即第一无线资源开销参数xOverhead-redcap∈{xOh0,xOh6,xOh12,xOh18,xOh30}。
可选地，第二无线资源开销参数取值包括以下至少一项：0、6、12，即第二无线资源开销参数xOverhead∈{xOh0,xOh6,xOh12}。
通过增大无线资源开销参数来减小最大传输块大小，使得第一最大传输块大小小于或等于第二最大传输块大小，从而减小轻型能力设备的缓冲区大小，降低硬件资源浪费。
在上述实施例中介绍了通过设置第一无线资源开销参数来降低N'RE，进而降低NRE，达到减小TBS的目的。下面将介绍通过频域映射参数来降低TBS的方案。
频域映射参数用于指示DMRS在每个PRB中所占的RE位置。由于解调参考信号的配置类型包括第一配置类型(即DRMS配置类型1)和第二配置类型(即DRMS配置类型2)，对于不同的配置类型，相应的频域映射参数也不同。
可选地，针对第一配置类型，轻型能力设备对应的第一频域映射参数k1＝0,1,2,...,n-1，n为PDSCH所占带宽部分内的资源单元数目，n为正整数，即PDSCH所在带宽部分的每个RE均映射DMRS。
可选地，针对第一配置类型，第一设备类型对应的第二频域映射参数k2＝4i+2k'+Δ，其中k’＝0,1，i＝0,1,...，k2<＝n,n为PDSCH所占带宽部分内的资源单元数目，n为正整数。
针对第一配置类型，Δ的取值可以参见下表1所示。
表1
p是天线端口、λ是正交码分组号，根据天线端口数目即可知道天线端口有哪些，进而可以确定每个天线端口的Δ取值。
以Δ＝1为例，则第一设备类型对应的第二频域映射参数k2＝1,3,5,7,...，即并非每个RE均映射DMRS，而是间隔映射。
针对不同的频域映射参数，相应的也不同，下面将结合图4和图5进行说明。
图4为本申请实施例提供的DMRS映射对比示意图一，如图4所示，示例的是DMRS配置类型1下两种不同设备类型的设备的DMRS的频域映射方式，示例以一个资源块(Resource Block，RB)为例，即12个RE的示意图，PDSCH频域上占据的至少一个RB的映射模式与单个RB的映射模式相同，同时图4中示例的是单符号DMRS映射。
在图4中，每个方格代表一个RE，左边示例的是普通设备的DMRS的频域映射方式，其第二频域映射参数k2＝1,3,5,7,...，即DMRS在一个PRB中频域映射位置k2＝1,3,5,7,9,11，则根据第二频域映射参数k2可得每个PRB中DMRS所占的RE数目为6，即
图4右边示例的是轻型能力设备的DMRS的频域映射方式，其第一频域映射参数k1＝0,1,2,...,n-1，即PDSCH所在带宽部分的每个RE均映射DMRS，因此根据第一频域映射参数k1可得每个PRB中DMRS所占的RE数目为12，即
图5为本申请实施例提供的DMRS映射对比示意图二，如图5所示，示例的是DRMS配置类型1下两种不同设备类型的设备的DMRS的频域映射方式，其中一个RB有12个RE，BWP中包括至少一个RB，记BWP中RB数目为N，则RE的数目为12*N，同时图5中示例的是双符号DMRS映射。
在图5中，每个方格代表一个RE，左边示例的是普通设备的DMRS的频域映射方式，其第二频域映射参数k2＝1,3,5,7,...,，即DMRS在一个PRB中频域映射位置k2＝1,3,5,7,9,11，则根据第二频域映射参数k2可得每个PRB中DMRS所占的RE数目为6，即
图5右边示例的是轻型能力设备的DMRS的频域映射方式，其第一频域映射参数k1＝0,1,2,...，即每个RE均映射DMRS，因此根据第一频域映射参数k1可得每个PRB中DMRS所占的RE数目为12，即
结合图4和图5的示例可知，在DMRS配置类型1下，在单符号DMRS或双符号DMRS映射，根据第一频域映射参数得到的为根据第二频域映射参数得到的的两倍，即
设针对轻型设备而言分配给PDSCH的每个PRB的可用RE的数量为N'RE1，针对普通设备而言分配给PDSCH的每个PRB的可用RE的数量为N'RE2，则根据上式(1)可得：

由于因此N'RE1≤N'RE2。根据式(2)至式(7)可知，分配给PDSCH的每个PRB的可用RE的数量N'RE与TBS成正相关关系。因此通过减小分配给PDSCH的每个PRB的可用RE的数量也可以减小TBS。即保证本申请中轻型能力设备的TBS小于或等于第一设备类型对应的TBS。
可选地，针对第二配置类型，轻型能力设备对应的第一频域映射参数k1＝4i+k’+Δ，k1小于或等于n，k’为0或1，i为0,1,2,...，Δ为大于或等于0的正整数；n为PDSCH所占带宽部分内的资源单元数目，n＝N*12，N为PDSCH所占的带宽部分大小，n为正整数。
可选地，针对第二配置类型，第一设备类型对应的第二频域映射参数k2＝6i+k’+Δ，k’＝0,1，k2小于或等于n，i为0,1,2,...，Δ为大于或等于0的正整数；n为PDSCH所占带宽部分内的资源单元数目，n为正整数。
可选地，针对第二配置类型，Δ的取值可以参见下表2所示。
表2
p是天线端口、λ是正交码分组号，根据天线端口数目即可知道天线端口有哪些，进而可以确定每个天线端口的Δ取值。
针对不同的频域映射参数，相应的也不同，下面将结合图6和图7进行说明。
图6为本申请实施例提供的DMRS映射对比示意图三，如图6所示，示例的是DRMS配置类型2下两种不同设备类型的设备的DMRS的频域映射方式，示例以一个RB为例，PDSCH频域上占据的至少一个RB的映射模式与单个RB的映射模式相同，一个RB包含12个RE，同时图6中示例的是单符号DMRS映射。
在图6中，每个方格代表一个载波，左边示例的是普通设备的DMRS的频域映射方式，其第二频域映射参数k2＝6i+k’+Δ，在Δ＝2时，DMRS在一个PRB中频域映射位置k2＝2,3,8,9，则根据第二频域映射参数k2可得每个PRB中DMRS所占的RE数目为4，即
图6右边示例的是轻型能力设备的DMRS的频域映射方式，其第一频域映射参数k1＝4i+k’+Δ，在Δ＝2时，DMRS在一个PRB中频域映射位置k1＝2,3,6,7,10,11，因此根据第一频域映射参数k1可得每个PRB中DMRS所占的RE数目为6，即
图7为本申请实施例提供的DMRS映射对比示意图四，如图7所示，示例的是DRMS配置类型2下两种不同设备类型的设备的DMRS的频域映射方式，示例以一个RB为例，PDSCH频域上占据的至少一个RB的映射模式与单个RB的映射模式相同，一个RB包含12个RE，同时图7中示例的是双符号DMRS映射。
在图7中，每个方格代表一个载波，左边示例的是普通设备的DMRS的频域映射方式，其第二频域映射参数k2＝6i+k’+Δ，在Δ＝2时，即DMRS在一个PRB中频域映射位置k2＝2,3,8,9， 则根据第二频域映射参数k2可得每个PRB中DMRS所占的RE数目为4，即
图7右边示例的是轻型能力设备的DMRS的频域映射方式，其第一频域映射参数k1＝4i+k’+Δ，在Δ＝2时，DMRS在一个PRB中频域映射位置k1＝2,3,6,7,10,11，因此根据第一频域映射参数k1可得每个PRB中DMRS所占的RE数目为6，即
结合图6和图7的示例可知，在DMRS配置类型2下，无论是单符号DMRS映射还是双符号DMRS映射，根据第一频域映射参数得到的均大于根据第二频域映射参数得到的即
设针对轻型设备而言分配给PDSCH的每个PRB的可用RE的数量为N'RE1，针对普通设备而言分配给PDSCH的每个PRB的可用RE的数量为N'RE2，则根据上式(1)可得：

由于因此N'RE1≤N'RE2。根据式(2)至式(7)可知，分配给PDSCH的每个PRB的可用RE的数量N'RE与TBS成正相关关系。因此通过减小分配给PDSCH的每个PRB的可用RE的数量也可以减小TBS。即本申请中轻型能力设备的TBS小于或等于第一设备类型对应的TBS。同时，由于增大了还能进一步增加信道估计的准确度，提高解码正确率。
在上述实施例中介绍了可以通过第一无线资源开销参数以及第一频域映射参数来降低NRE，从而降低中间变量Ninfo，达到降低最大传输块大小的目的。根据式(3)可知，中间变量Ninfo的取值除了和NRE相关外，还和调制策略参数Qm以及目标码率R相关。下面将介绍根据调制策略参数Qm以及目标码率R来降低最大传输块大小的方案。
可选地，缓存信息中包括第一调制与编码方式参数。
可选地，第一调制与编码方式参数包括第一调制策略参数和/或第一目标码率。
可选地，根据调制与编码方式索引，可以确定第一调制策略参数和/或第一目标码率。
本申请实施例中，针对轻型能力设备和普通设备均分别设置有相应的MCS映射表格。若在随机接入过程中网络设备识别出终端设备的类型，则根据终端设备的类型采用相应的MCS映射表格，确定相应的调制策略参数和/或目标码率。可选地，除了普通设备的MCS映射表格外，终端设备和网络设备均预存了一个新的MCS表格，即预设调制与编码方式列表，用于确定轻型设备的第一调制策略参数和/或第一目标码率。
可选地，针对任意调制与编码方式索引，第一调制策略参数小于或等于第一设备类型对应的第二调制策略参数。
可选地，针对任意调制与编码方式索引，第一目标码率小于或等于第一设备类型对应的第二目标码率。
下表3示例了轻型能力设备的预设调制与编码方式列表，即轻型能力设备的MCS映射表格。
表3

下表4至表6示例了普通设备的预设调制与编码方式列表，即普通设备的MCS映射表格。
表4
表5

表6

如表3至表6所示，针对任意调制与编码方式索引，对应的第一调制策略参数均小于或等于第二调制策略参数，对应的第一目标码率均小于或等于第二目标码率。例如，当调制与编码方式索引为5时，根据表1可得第一调制策略参数为2，第一目标码率为157，根据表3可得第二调制策略参数为4，第二目标码率为378，等等。
由于第一调制策略参数小于或等于第二调制策略参数，且第一目标码率小于或等于第二目标码率，因此根据上式(4)可知，在相同的NRE下，轻型能力设备对应的中间变量Ninfo小于或等于普通设备对应的中间变量Ninfo，而中间变量Ninfo与最大传输块大小成正相关关系，因此轻型能力设备的第一最大传输块大小小于或等于普通设备的第二最大传输块大小，由此可得轻型能力设备的层1缓冲区大小小于或等于普通设备的层1缓冲区大小。
在上述实施例中，介绍了通过第一无线资源开销参数、第一频域映射参数、第一调制与编码方式参数中的至少一项来减小Ninfo，进而减小TBS的方案。下面将介绍通过第一比例因子修改Ninfo的计算公式来减小Ninfo，进而减小TBS的方案。
可选地，缓存信息中还包括第一比例因子，根据可用资源单元数目、第一调制与编码方式参数和第一比例因子中的至少一项，确定第一最大传输块大小。
可选地，针对第一设备类型的终端设备而言，其中间变量Ninfo＝NRE*R*Qm*v或Ninfo＝S2*NRE*R*Qm*v。可选地，当承载业务数据的信道为小区无线网络临时标识符加扰的物理下行共享信道、调制编码方式的小区无线网络临时标识符加扰的物理下行共享信道、临时小区的无线网络临时标识符加扰的物理下行共享信道、配置调度的无线网络临时标识符加扰的物理下行共享信道、系统信息无线网络临时标识符加扰的物理下行共享信道中的任意一项时，Ninfo＝NRE*R*Qm*v，当承载业务数据的信道为寻呼无线网络临时标识符加扰的物理下行共享信道或随机接入无线网络临时标识符加扰的物理下行共享信道时，Ninfo＝S2*NRE*R*Qm*v，S2为第二比例因子，S2的取值可以根据表7确定。
表7
可选地，针对轻型能力设备而言，其中间变量Ninfo的计算公式如下：
Ninfo＝S1*NRE*R*Qm*v                            (9)
可选地，承载业务数据的信道包括以下至少一项：小区无线网络临时标识符加扰的物理下行共享信道、调制编码方式的小区无线网络临时标识符加扰的物理下行共享信道、临时小区的无线网络临时标识符加扰的物理下行共享信道、配置调度的无线网络临时标识符加扰的物理下行共享信道、系统信息无线网络临时标识符加扰的物理下行共享信道、寻呼无线网络临时标识符加扰的物理下行共享信道、随机接入无线网络临时标识符加扰的物理下行共享信道。S1为第一比例因子，S1的取值可以根据表8确定。
表8

当承载业务数据的信道为小区无线网络临时标识符加扰的物理下行共享信道、调制编码方式的小区无线网络临时标识符加扰的物理下行共享信道、临时小区的无线网络临时标识符加扰的物理下行共享信道、配置调度的无线网络临时标识符加扰的物理下行共享信道、系统信息无线网络临时标识符加扰的物理下行共享信道中的任意一项时，对于第一设备类型而言，其第二比例因子S2相当于为1，而第一比例因子S1小于或等于1，因此第一比例因子小于或等于第二比例因子，进而第一最大传输块大小小于或等于第二最大传输块大小，由此可得轻型能力设备的层1缓冲区大小小于或等于普通设备的层1缓冲区大小。
当承载业务数据的信道为寻呼无线网络临时标识符加扰的物理下行共享信道或随机接入无线网络临时标识符加扰的物理下行共享信道时，对于第一设备类型而言，其第二比例因子可参见表7，而轻型能力设备的第一比例因子可参见表8。针对任意一个传输块缩放域(transport block scaling field)，其对应的第一比例因子均小于或等于第二比例因子，进而第一最大传输块大小小于或等于第二最大传输块大小，由此可得轻型能力设备的层1缓冲区大小小于或等于普通设备的层1缓冲区大小。
综上所述，本申请实施例中通过扩展第一比例因子的适用范围，在承载业务数据的信道为小区无线网络临时标识符加扰的物理下行共享信道、调制编码方式的小区无线网络临时标识符加扰的物理下行共享信道、临时小区的无线网络临时标识符加扰的物理下行共享信道、配置调度的无线网络临时标识符加扰的物理下行共享信道、系统信息无线网络临时标识符加扰的物理下行共享信道中的任意一项时，均通过第一比例因子确定中间变量Ninfo，与第一设备类型相比，减小了中间变量Ninfo，进而第一最大传输块大小小于或等于第二最大传输块大小，由此可得轻型能力设备的层1缓冲区大小小于或等于普通设备的层1缓冲区大小。即通过第一比例因子减小了层1缓冲区大小，进而减小了轻型能力设备的缓冲区大小。
在上述实施例中，介绍了通过减小最大传输块大小从而减小层1缓冲区大小的方案。终端设备的缓冲区包括层1缓冲区和/或层2缓冲区，可选地，层2缓冲区大小与数据速率成正相关关系，可以通过减小数据速率来减小层2缓冲区大小。可选地，数据速率的计算公式如下：
本申请实施例中，为下行链路共享信道或上行链路共享信道支持的最大层数；为下行链路共享信道或上行链路共享信道支持的最大调制阶数；f(j)为由高层参数scalingFactor指定的缩放因子；Rmax＝948/1024；为一个子帧中的OFDM符号的平均持续时长；μ为子载波间隔；BW(j)为给定频带中支持的最大带宽部分；为子载波间隔为μ的带宽部分BW(j)的最大RB分配数目；OH(j)为开销因子。
可选地，可以限定f(j)的取值属于{0.1,0.2,0.3,0.15}，或者，限定f(j)的取值为符合预设规则的值，例如步长为0.1的取值且不超过0.5(即f(j)的取值属于{0.1,0.2,0.3,0.4,0.5})或者符合其他预设规则的值。
可选地，的乘积为小于4的其他值，例如的乘积小于预设固定值的取值或的乘积为满足预设规则的值，例如2-1＝0.5，21＝2，等等。
可选地，的乘积取值还可以与物理下行链路共享信道的子载波间隔或物理上行链路共享信道的子载波间隔有关，具体地，其中u为物理下行链路共享信道的子载波间隔或物理上行链路共享信道的子载波间隔，X为子载波间隔为15KHz时，满足最小峰值数据速率需求的的乘积。比如当物理下行链路共享 信道的子载波间隔或物理上行链路共享信道的子载波间隔为15KHz时，则当物理下行链路共享信道的子载波间隔或物理上行链路共享信道的子载波间隔为30KHz时，
通过减小f(j)以及限定的乘积可以减小数据速率，进而减小层2缓冲区的大小，最终达到减小终端设备的层2缓冲区大小的目的。
图8为本申请实施例提供的处理方法的信令图二，如图8所示，该方法可以应用于终端设备，包括以下步骤：
S81，网络设备向终端设备发送业务数据的缓存信息，缓存信息用于指示第一最大传输块大小。

本申请实施例中涉及的网络设备也可称为RAN设备。RAN设备与终端设备连接，用于接收终端设备的数据并发送给核心网设备。RAN设备在不同通信系统中对应不同的设备，例如，在2G系统中对应基站与基站控制器，在3G系统中对应基站与RNC，在4G系统中对应演进型基站，在5G系统中对应5G系统，如NR中的接入网设备(例如gNB，CU，DU)。
网络设备可以向终端设备发送业务数据的缓存信息，通过缓存信息指示第一最大传输块大小。
S82，根据预设参数确定第一最大传输块大小，第一最大传输块大小小于或等于第一设备类型对应的第二最大传输块大小。
本申请实施例中的终端设备可以是普通设备，也可以是轻型能力设备。
可选地，本申请实施例中的终端设备为轻型能力设备，第一设备类型的设备为普通设备。根据预设参数可以确定终端设备的第一最大传输块大小，第一最大传输块大小小于或等于第一设备类型对应的最大传输块大小，即第一最大传输块大小小于或等于普通设备对应的最大传输块大小。
S83，根据第一最大传输块大小确定业务数据的缓冲区大小。
可选地，业务数据的缓冲区大小包括层1缓冲区大小和/或层2缓冲区大小，层1缓冲区大小与终端设备的最大传输块大小成正相关。本申请实施例中，终端设备的第一最大传输块大小小于或等于第一设备类型对应的最大传输块大小，因此终端设备的层1缓冲区大小小于或等于第一设备类型对应的层1缓冲区大小，进而终端设备的业务数据的缓冲区大小小于或等于第一设备类型对应的业务数据的缓冲区大小。
终端设备的最大传输块大小的计算过程可参见上述式(1)至式(8)，进而根据最大传输块大小确定层1缓冲区大小。可选地，上述计算最大传输块大小的方案，适用于第一设备类型的终端设备，即普通设备，也适用于第二设备类型的终端设备，即轻型能力设备。
式(6)至式(8)示例了在不同的码率R以及N'info的不同取值下计算最大传输块TBS的方式。根据式(6)至式(8)可知，TBS与N'info是正相关的，即N'info越大，则TBS越大，反之N'info越小，则TBS越小。
式(4)和式(5)示例了在Ninfo的不同取值范围下计算N'info的方式，根据式(4)和式(5)可知，N'info与Ninfo也是正相关的，即Ninfo越大，则N'info越大，反之Ninfo越小，则N'info越小。
式(3)示例了Ninfo的大小与NRE、R、Qm等相关，综上所述可知，可以通过减小NRE、R、Qm的值减小TBS，进而达到减小终端设备的缓冲区大小的目的，也可以通过修改式(3)中Ninfo的计算公式来减小Ninfo，从而达到减小TBS进而减小终端设备的缓冲区大小的目的。
本申请实施例中，根据预设参数可以确定第一最大传输块大小，可选地，预设参数包括PDSCH的每个PRB中可用资源单元数目、第一调制与编码方式参数、第一比例因子中的至少一项。可选地，通过PDSCH的每个PRB中可用资源单元数目可以减小NRE的值，通过第一调制与编码方式参数可以减小R和Qm的值，通过第一比例因子可以在式(3)的基础上修 改Ninfo的计算公式来减小Ninfo，从而减小Ninfo。即，通过预设参数中的各项参数能够达到减小TBS进而减小终端设备的缓冲区大小的目的。下面将对预设参数中的各项参数分别进行介绍。
可选地，PDSCH的每个PRB中可用资源单元数目的确定方式为：根据第一无线资源开销参数和/或第一频域映射参数，确定PDSCH的每个PRB中可用资源单元数目，然后根据可用资源单元数目、第一调制与编码方式参数和第一比例因子中的至少一项，确定第一最大传输块大小。
可选地，缓存信息中包括第一无线资源开销参数，第一无线资源开销参数为新定义的RRC参数xOverhead-redcap，用于指示终端设备PDSCH可用PRB上的其他资源的预留开销。
可选地，第一无线资源开销参数为轻型设备的无线资源开销参数。
可选地，第一无线资源开销参数大于或等于第一设备类型的无线资源开销参数。
根据式(1)可知，根据无线资源开销参数可以获取分配给PDSCH的每个PRB的可用RE的数量N'RE。设第一无线资源开销参数为第一设备类型的第二无线资源开销参数为则可以分别得到分配给PDSCH的每个PRB的可用RE的数量如下：

可选地，N'RE1为轻型能力设备对应的分配给PDSCH的每个PRB的可用RE的数量，N'RE2为普通设备对应的分配给PDSCH的每个PRB的可用RE的数量。由于因此N'RE1≤N'RE2，即相比于第一设备类型的终端设备而言，本申请实施例中通过增大无线资源开销参数的取值来减小分配给PDSCH的每个PRB的可用RE的数量。根据式(2)至式(7)可知，分配给PDSCH的每个PRB的可用RE的数量N'RE与TBS成正相关关系。因此通过减小分配给PDSCH的每个PRB的可用RE的数量也可以减小TBS。即本申请中轻型能力设备的TBS小于或等于第一设备类型对应的TBS。
可选地，第一无线资源开销参数取值包括以下至少一项：0、6、12、18、30，即第一无线资源开销参数xOverhead-redcap∈{xOh0,xOh6,xOh12,xOh18,xOh30}。
可选地，第二无线资源开销参数取值包括以下至少一项：0、6、12，即第二无线资源开销参数xOverhead∈{xOh0,xOh6,xOh12}。
通过增大无线资源开销参数来减小最大传输块大小，使得第一最大传输块大小小于或等于第二最大传输块大小，从而减小轻型能力设备的缓冲区大小，降低硬件资源浪费。
在上述实施例中介绍了通过设置第一无线资源开销参数来降低N'RE，进而降低NRE，达到减小TBS的目的。下面将介绍通过频域映射参数来降低TBS的方案。
频域映射参数用于指示DMRS在每个PRB中所占的RE位置。由于解调参考信号的配置类型包括第一配置类型(即DRMS配置类型1)和第二配置类型(即DRMS配置类型2)，对于不同的配置类型，相应的频域映射参数也不同。
可选地，针对第一配置类型，轻型能力设备对应的第一频域映射参数k1＝0,1,2,...,n-1，n为PDSCH所占带宽部分内的资源单元数目，n为正整数，即PDSCH所在带宽部分的每个RE均映射DMRS。
可选地，针对第一配置类型，第一设备类型对应的第二频域映射参数k2＝4n+2k'+Δ，其中k’＝0,1。可选地，针对第一配置类型，Δ的取值可以参见表1。
以Δ＝1为例，则第一设备类型对应的第二频域映射参数k2＝1,3,5,7,...,，n为PDSCH所占带宽部分内的资源单元数目，n为正整数，即并非每个RE均映射DMRS，而是间隔映射。

在图4中，每个方格代表一个RE，左边示例的是普通设备的DMRS的频域映射方式，其第二频域映射参数k2＝1,3,5,7,...，即k2＝1,3,5,7,9,11，则根据第二频域映射参数k’可得每个 PRB中DMRS所占的RE数目为6，即
图4右边示例的是轻型能力设备的DMRS的频域映射方式，其第一频域映射参数k1＝0,1,2,...,n-1，即PDSCH所在带宽部分的每个RE均映射DMRS，因此根据第一频域映射参数k1可得每个PRB中DMRS所占的RE数目为12，即

在图6中，每个方格代表一个载波，左边示例的是普通设备的DMRS的频域映射方式，其第二频域映射参数k2＝6i+k’+Δ，在Δ＝2时，k2＝2,3,8,9，则根据第二频域映射参数k2可得每个PRB中DMRS所占的RE数目为4，即
图6右边示例的是轻型能力设备的DMRS的频域映射方式，其第一频域映射参数k1＝4i+k’+Δ，在Δ＝2时，k1＝2,3,6,7,10,11，因此根据第一频域映射参数k1可得每个PRB中DMRS所占的RE数目为6，即

设针对轻型设备而言分配给PDSCH的每个PRB的可用RE的数量为N'RE1，针对普通设备而言分配给PDSCH的每个PRB的可用RE的数量为N'RE2，则根据上式(1)可得：

由于因此N'RE1≤N'RE2。根据式(2)至式(7)可知，分配给PDSCH的每个PRB的可用RE的数量N'RE与TBS成正相关关系。因此通过减小分配给PDSCH的每个PRB的可用RE的数量也可以减小TBS。即本申请中轻型能力设备的TBS小于或等于第一设备类型对应的TBS。同时，由于增大了还能进一步增加信道估计的准确度，提高解码正确率。
在上述实施例中介绍了可以通过第一无线资源开销参数以及第一频域映射参数来降低NRE，从而降低中间变量Ninfo，达到降低最大传输块大小的目的。根据式(3)可知，中间变量Ninfo的取值除了和NRE相关外，还和调制策略参数Qm以及目标码率R相关。下面将介绍根据调制策略参数Qm以及目标码率R来降低最大传输块大小的方案。

可选地，针对任意调制与编码方式索引，第一调制策略参数小于或等于第一设备类型对应的第二调制策略参数。
可选地，针对任意调制与编码方式索引，第一目标码率小于或等于第一设备类型对应的第二目标码率。
表3示例了轻型能力设备的预设调制与编码方式列表，即轻型能力设备的MCS映射表格，表4至表6示例了普通设备的预设调制与编码方式列表，即普通设备的MCS映射表格。如表3至表6所示，针对任意调制与编码方式索引，对应的第一调制策略参数均小于或等于第二调制策略参数，对应的第一目标码率均小于或等于第二目标码率。例如，当调制与编码方式索引为5时，根据表3可得第一调制策略参数为2，第一目标码率为157，根据表5可得第二调制策略参数为4，第二目标码率为378，等等。
由于第一调制策略参数小于或等于第二调制策略参数，且第一目标码率小于或等于第二目标码率，因此根据上式(4)可知，在相同的NRE下，轻型能力设备对应的中间变量Ninfo小于或等于普通设备对应的中间变量Ninfo，而中间变量Ninfo与最大传输块大小成正相关关系，因此轻型能力设备的第一最大传输块大小小于或等于普通设备的第二最大传输块大小，由此可得轻型能力设备的层1缓冲区大小小于或等于普通设备的层1缓冲区大小。
在上述实施例中，介绍了通过第一无线资源开销参数、第一频域映射参数、第一调制与编码方式参数中的至少一项来减小Ninfo，进而减小TBS的方案。下面将介绍通过第一比例因子修改Ninfo的计算公式来减小Ninfo，进而减小TBS的方案。

当承载业务数据的信道为寻呼无线网络临时标识符加扰的物理下行共享信道或随机接入无线网络临时标识符加扰的物理下行共享信道时，对于第一设备类型而言，其第二比例因子可参见表7，而轻型能力设备的第一比例因子可参见表8。针对任意一个传输块缩放域，其对应的第一比例因子均小于或等于第二比例因子，进而第一最大传输块大小小于或等于第二最大传输块大小，由此可得轻型能力设备的层1缓冲区大小小于或等于普通设备的层1缓冲区大小。
综上所述，本申请实施例中通过扩展第一比例因子的适用范围，在承载业务数据的信道为小区无线网络临时标识符加扰的物理下行共享信道、调制编码方式的小区无线网络临时标识符加扰的物理下行共享信道、临时小区的无线网络临时标识符加扰的物理下行共享信道、配置调度的无线网络临时标识符加扰的物理下行共享信道、系统信息无线网络临时标识符加扰的物理下行共享信道中的任意一项时，均通过第一比例因子确定中间变量Ninfo，与第一设备类型相比，减小了中间变量Ninfo，进而第一最大传输块大小小于或等于第二最大传输块大小，由此可得轻型能力设备的层1缓冲区大小小于或等于普通设备的层1缓冲区大小。即通过第一比例因子减小了层1缓冲区大小，进而减小了轻型能力设备的缓冲区大小。
本申请实施例中，限定f(j)的取值属于{0.1,0.2,0.3,0.15}，或者，限定f(j)的取值为符合预设规则的值，例如步长为0.1的取值且不超过0.5(即f(j)的取值属于{0.1,0.2,0.3,0.4,0.5})或者符合其他预设规则的值。限定的乘积为小于4的其他值，例如乘积小于预设值的取值或者满足预设规则的值，例如2-1＝0.5，21＝2，等等。通过减小f(j)以及限定 的乘积来减小数据速率，进而减小层2缓冲区的大小，进一步达到减小终端设备的缓冲区大小的目的。
