Description

一种通信处理方法和装置
本申请要求2017年11月17日递交的，申请号为201711149022.4的中国专利申请，该中国专利申请通过引用结合在本申请中。
技术领域
本申请实施例涉及无线通信领域，尤其涉及一种通信处理方法和装置。
背景技术
在无线通信系统中，终端和服务所述终端的无线接入设备按照协议层，分别包括物理(physical,PHY)层，媒体接入控制(medium access control,MAC)层，无线链路控制(radio link control，RLC)层以及分组数据汇聚层(packet data convergence protocol,PDCP)以及无线资源控制(radio resource control,RRC)层等等。
物理信道是用于传输经过物理层处理后信息的通道。不同种类物理信道可以传输经过所述物理层处理后的不同种类信息。其中，物理下行控制信道(physical downlink control channel,PDCCH)是传输下行链路上物理层控制信令的主要信道，可以用于指示上行数据传输或者下行数据传输的时频资源位置。
在物理信道上，时频资源被划分为多个栅格，一个最小栅格由一个时域符号和一个单位频率构成。可选地，一个时域符号可以为正交频分复用(orthogonal frequency-division multiplexing,OFDM)符号或者单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)符号；一个单位频率可以为一个15kHz或60Hz的子载波。一个传输时间单元可包含至少两个时域符号，例如7或14个时域符号。
在长期演进(long term evolution，LTE)时分复用(time division duplex,TDD)系统中，一个传输时间单元为一个子帧(sub-frame),这个子帧包含两个时隙，每个时隙包含6或7个时域符号。无线接入设备按照整个传输时间单元的粒度进行数据传输的时域资源配置，即一个传输时间单元的类型属于下行时域资源或上行时域资源。
在第五代无线通信系统(简称5G系统)中，一个传输时间单元为一个包含7或14个时域符号的时隙。无线接入设备按照一个时隙中的至少一个时域符号的粒度进行数据传输的时域资源配置，即一个时隙中有些时域符号属于上行时域资源类型，有些时域符号的类型属于下行时域资源类型，还有些时域符号的类型为未知(unknown)类型，其中，在未知类型的时域符号上终端既不接收下行数据也不发送上行数据。5G系统中的无线接入设备可以通过PDCCH，例如组公共(Group Common)PDCCH，向终端指示这个时隙中每个时域符号的类型属于上行时域资源类型，下行时域资源还是未知类型。
在LTE TDD系统和5G系统共存(co-existence)的情况下，终端可由这两个系统中共同服务。5G系统为了能够与LTE TDD系统共存，可进行灵活的时域资源配置实现与LTE TDD系统的共存。但在相同数据传输时刻，某些传输时间单元或某些时域符号在这两个系统中的一个系统中属于上行时域资源类型而存在上行数据传输，在另一个系统中属于下行时域资源类型而存在下行数据传输，而造成干扰。

具体实施方式
图1所示的无线通信系统架构示意图中，无线接入设备，如基站,无线局域网接入点等各种传输接收点(transmission reception point，TRP)，为终端提供授权频谱下的接入服务或非授权频谱下的接入服务。所述终端和所述无线接入设备在上行链路和下行链路上按照协议层在空中接口上传输各种数据，例如控制信令或业务数据。其中，控制信令主要在控制信道上传输，业务数据主要在业务信道上传输。其中，无线接入设备按照协议层划分，可进一步包含一个控制单元(control unit,CU)和至少一个分布式单元(distributed unit,DU)。所述CU用于实现无线接入设备的PDCP层，RRC层及其以上协议层的功能；所述DU用于实现PDCP层以下协议层的功能。
图1所示的无线通信系统可以是新无线(New Radio，NR)系统(也称5G系统)、LTE、先进的长期演进(Advanced long termevolution，LTE-A)系统、演进的长期演进(evolved Long Term Evolution，eLTE)系统等无线通信系统。
本申请各个实施例中，终端又称之为用户设备(User Equipment，UE)，是一种向用户提供语音和/或数据连通性的设备，例如，具有无线连接功能的手持式设备、车载设备等。常见的终端例如包括：手机、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，例如智能手表、智能手环、计步器等。
图1中，LTE TDD系统使用LTE TDD系统时域资源配置(如表1所示)可以和5G系统共存，共同为终端1提供通信服务，其中，LTE TDD系统的无线接入设备1和5G系统中的无线 接入设备2可以是分别独立的物理设备，也可以是共站的同一物理设备。除了该共存场景，在LTE TDD系统中的小区和5G系统中的小区相邻的情况，5G系统可以为终端1提供通信服务，LTE TDD系统可以为终端2提供通信服务。
从表1中可以看出，LTE TDD系统时域资源配置包括5ms周期和10ms周期两类。对于5ms周期，子帧1和子帧6固定为特殊子帧；对于10ms周期，子帧1固定为特殊子帧。每个特殊子帧包括特殊子帧的下行部分(Downlink Part of the Special Subframe),保护间隔(Guard Period,GP)，以及特殊子帧的上行部分(Uplink Part of the Special Subframe)。在每个特殊子帧后的下一个子帧总是用于传输上行数据。
由于5G系统时域资源配置较为灵活，5G可按照上述LTE TDD系统时域资源配置的特点，穷举出与表1中LTE TDD系统任意一个时域资源配置对应的5G系统的时域资源配置，其中，5G系统的时域资源配置包括下行时域资源配置，上行时域资源配置和未知类型的配置。
以下行时域资源配置的某一个周期为例，下行时域资源配置：在这个周期的开始配置x1个传输时间单位为下行时域资源类型(x1取值为0到这个周期中传输时间单元的总数)，接着在第x1+1个传输时间单元中配置x2个时域符号为下行时域资源类型(x2的取值为0到这个传输时间单元的时域符号总数)，x3个时域符号用于未知类型以及x4个时域符号为上行时域资源类型(x2+x3+x4＝这个传输时间单元的时域符号个数)，再接着从第x1+2个传输时间单元开始配置y1个传输时间单元为上行时域资源类型。5G系统可按照表1中不同LTE TDD时域资源配置的，进行上述配置，使得5G系统和LTE TDD系统共存。
表1 LTE时域资源配置
Figure PCTCN2018114980-appb-000003
D表示下行子帧(LTE系统中一个传输时间单元即为一个子帧)，用于下行数据传输；U表示上行子帧，用于上行数据传输；S表示特殊子帧。
通过上述方式，虽然能够使得LTE TDD系统和5G系统共存，但在相同数据传输时刻，某些传输时间单元上既有上行数据传输又有下行数据传输的情况，导致信号干扰。例如表2所示一个无线帧中5G和LTE TDD时域资源配置2共存的情况，假设相同数据传输时刻LTE TDD系统和5G系统均从传输时间单元0开始传输，传输时间单元2,3,4,7,8,9上由于既有上行数据传输又有下行数据导致信号干扰。
表2 5G与LTE TDD时域资源配置2共存
Figure PCTCN2018114980-appb-000004
Figure PCTCN2018114980-appb-000005
D+Un+U表示这个传输时间单元中部分时域符号为下行时域资源类型，用于下行数据传输，部分时域符号是未知类型，部分时域符号为上行时域资源类型，用于上行数据传输。
为了便于理解，上述描述以LTE系统和5G系统共存为例进行了说明，但是对于任意两种不同无线通信系统时域资源配置都可能出现上述干扰问题。
因此，鉴于上述技术问题，本申请第一实施例提供一种通信处理方法，通过确定不同无线通信系统时域资源配置之间时间偏移量，所述时间偏移量用于可避免同一数据传输时刻的传输时间单元上既有上行数据传输又有下行数据传输带来的干扰。需要说明的是，本申请各个实施例中的数据，包括业务数据或控制信令。本申请各个实施例中，无线通信系统所执行的动作，可由这个无线通信系统中的无线接入设备来执行。不同无线通信系统的无线接入设备可是物理上独立的两个设备，也可以是共站的同一物理设备。
如图2所示通信处理方法流程示意图，第一实施例包括以下内容。
201，第一无线通信系统确定所述第一无线通信系统中时域资源配置的时间偏移量。
其中，时间偏移量的单位可以是传输时间单元也可以是至少一个时域符号，至少一个时隙或至少一个子帧。所述时间偏移量可用于第一无线通信系统与第二无线通信系统在上下行转换周期内具有相同时域资源类型的传输时间单元的对齐。
这里的对齐，可以理解为在同一数据传输时刻，第一无线通信系统中数据传输的时域资源类型与第二无线通信系统中数据传输的时域资源类型相同或者互不干扰(例如对于5G系统中未知类型的时域资源上，由于终端既不接收也不发送，因此无论LTE系统在这个时域资源上是什么时域资源类型，也不会产生干扰)。简单说，在某个数据传输时刻，第一无线通信系统和第二无线通信系统数据传输的时域资源类型要么是上行时域资源类型进行上行数据传输，要么是下行时域资源类型进行下行数据传输，要么有个是未知类型，从而可以避免相同数据传输时刻上，上行数据传输和下行数据传输的同时存在。
可选地，第一无线通信系统为5G系统，第二无线通信系统为LTE TDD系统，一个传输时间单元可以为一个时隙，包含14个时域符号。
作为一个示例，仍然以LTE TDD系统时域资源配置2为例。如图3所示，LTE TDD系统的传输时间单元0和5G系统的传输时间单元2为下行时域资源类型，并且，对于同一数据传输时刻，如果5G系统进行数据传输时偏移2个传输时间单元，则无论在哪个数据传输时刻LTE TDD系统和5G系统在每个传输时间单元上的时域资源类型相同，从而可避免干扰的产生，则确定所述时间偏移量为2个传输时间单元。
202，第一无线通信系统向所述终端发送第一信息，所述第一信息用于确定所述时间偏移量；相应地，所述终端接收所述第一信息，并根据所述第一信息确定出所述时间偏移量。
可选地，第一信息可以承载在系统消息，例如主信息块(master information block,MIB)或系统信息块(system information block,SIB)或剩余系统信息(remaining system information)或其他系统信息(other system information,OSI)，广播消息，RRC消息， MAC消息或PDCCH的下行控制信息中。
可选地，第一信息为所述时间偏移量本身，或者时间偏移量的索引；或者，所述第一信息为所述第二无线通信系统中所述时域资源配置的索引，其中，所述第二无线通信系统中所述时域资源配置与所述时间偏移量对应。
作为一种实现方式，在所述第一无线通信系统为第五代无线通信系统，所述第二无线通信系统为LTE系统，所述第二无线通信系统中所述时域资源配置与所述时间偏移量的对应关系如表3所示：
表3
Figure PCTCN2018114980-appb-000006
其中，E为所述第二无线通信系统与第一无线通信系统之间的定时偏差，当第一无线通信系统和第二无线通信系统定时同步时，所述定时偏差取值为0，定时偏差表示第二通信系统中的系统帧中的第一个子帧或时隙相对于第一通信系统的系统帧中的第一个子帧或时隙的提前量，所述提前量可以是时隙或子帧的个数，也可以是绝对的时间大小，％表示取模运算。
这种情况下，第一信息具体可以指示第二无线通信系统的上行配置的索引，所述终端可根据预置在所述终端内的所述第二无线通信系统中所述时域资源配置与所述时间偏移量的对应关系，确定所述时间偏移量。
203，第一无线通信系统根据所述时间偏移量确定所述第一无线通信系统中时域资源配置的时域位置；相应地，所述终端根据所述时间偏移量确定出所述时域位置。
由于第一无线通信系统和第二无线通信系统可能存在定时偏差，使得这两个通信系统的传输时间单元0并不是时间上同步的。所述定时偏差可以是绝对时间大小或者传输时间单元的个数。如图3所示，则在确定第一无线通信系统中时域资源配置的时域位置时，第一无线通信系统根据所述时间偏移量和所述定时偏差确定出所述时域位置。相应地，第一无线通信系统还可以向终端发送第二信息，所述第二信息指示所述定时偏差是否存在。如果存在，则所述第二信息中具体指示所述定时偏差的大小。从而，终端在接收到所述第二信息后，可根据所述时间偏移量和所述定时偏差确定出第一无线通信系统的时域资源配置的所述时域位置。
可选地，第一无线通信系统也可以不将定时偏差通知给终端，而是可进一步根据定时偏差确定所述时间偏移量后，将所述时间偏移量通知给所述终端，使得终端无需再对定时偏差进行处理。
204，所述终端和所述第一无线通信系统在所述时域位置上按照所述第一无线通信系统中时域资源配置进行所述数据传输。
应用第一实施例提供的技术方案，通过确定第一无线通信系统时域资源配置的时间偏移 量，使得第一无线通信系统与第二无线通信系统在上下行转换周期内具有相同时域资源类型的传输时间单元的对齐，从而避免同一数据传输时刻的传输时间单元上既有上行数据传输又有下行数据传输带来的干扰。
本申请第二实施例提供另一种通信处理方法，与第一实施例相比，直接根据第二无线通信系统的时域资源配置确定第一无线通信系统在每个传输时间单元上的数据传输方式，使得在相同或时域符号上要么用于上行数据传输要么用于下行数据传输，从而避免干扰产生。如图4所示，第二实施例包括以下内容。
400，第一无线通信系统根据第二无线通信系统的时域资源配置，确定所述第一无线通信系统在上下行转换周期内与所述第二无线通信系统的时域资源配置对齐的第一无线通信系统的时域资源配置，其中，所述第一无线通信系统与所述第二无线通信系统在相同传输时间单元上具有相同时域资源类型。
例如，针对第一无线通信系统和第二无线通信系统中任意相同传输时间单元，第一无线通信系统在这个传输时间单元上要么均为下行时域资源类型，要么均为上行时域资源类型，要么这个传输时间单元中相同时域符号上要么均为下行时域资源类型，要么均为上行时域资源类型。
401，所述终端接收所述第一无线通信系统发送的特定于小区的系统信息，所述系统信息中指示所述终端所在小区内所有终端上行时域资源类型或下行时域资源类型的传输时间单元或时域符号。
可选地，402，所述终端接收所述第一无线通信系统发送的特定于所述终端的指示信息，所述指示信息指示特定于所述终端上行时域资源类型或下行时域资源类型的传输时间单元或时域符号。
在401中，由于系统信息可以是在小区内进行广播的，因而所述终端所在小区中所有终端都能够接收到所述系统信息，并确定出所述系统信息指示的上行时域资源类型或下行时域资源类型的传输时间单元或某个传输时间单元中的某些时域符号。对于所述系统信息没有指示出是传输时间单元或时域符号，所述终端可以默认这些传输时间单元为未知类型。
在402中，由于指示信息是特定于所述终端的，这个终端可以确定出所述指示信息所指示的传输时间单元或时域符号哪些为上行时域资源类型哪些为下行时域资源类型。其中，所述指示信息指示的上行时域资源类型或下行数据资源类型的传输时间单元或时域符号为401中所述系统信息未指示的传输时间单元或时域符号，或者指示为未知类型的传输时间单元或时域符号。
作为本实施例的可能实现方式，5G系统根据LTE TDD时域资源配置0-5确定出分别与LTE TDD时域资源配置0-5对齐的5G系统时域资源配置。5G系统可向终端发送特定于所述终端所在小区的系统信息和特定于所述终端的指示信息，来通知5G系统时域资源配置。
(1)对于LTE TDD时域资源配置0，上下行转换周期为5个传输时间单元，通过系统信息通知上下行转换周期内每个传输时间单元或时域符号所属的时域资源类型，这种情况下无需再通过特定于所述终端的指示信息进行通知。
