技术领域
本公开实施例涉及通信技术领域，具体涉及一种信号处理方法和设备。
背景技术
在第五代(5th Generation，5G)通信系统中，或称为新空口(New Radio，NR)系统中，非授权频段可以作为授权频段(licensed band)的补充，以帮助运营商对服务进行扩容。为了与NR部署保持一致并尽可能的最大化基于NR的非授权接入，非授权频段可以工作在5GHz，37GHz和60GHz频段。非授权频段的大带宽(80或者100MHz)能够减小基站和终端设备(例如：用户设备(User Equipment，UE))的实施复杂度。由于非授权频段由多种无线接入技术(Radio Access Technology，RATs)共用，例如：无线保真(Wireless Fidelity，WiFi)，雷达，长期演进授权频谱辅助接入(Long Term Evolution License Assisted Access，LTE-LAA)等，因此在某些国家或者区域，非授权频段在使用时必须符合规定(regulation)以保证所有设备可以公平的使用该资源，例如：先听后送(Listen Before Talk，LBT)，最大信道占用时间(Maximum Channel Occupancy Time，MCOT)等规则。
当传输节点需要发送信息是，需要先做LBT时，对周围的节点进行功率检测(Energy Detection，ED)，当检测到的功率低于一个门限时，认为信道为空闲(idle)，传输节点可以进行发送。反之，则认为信道为忙，传输节点不能进行发送。传输节点可以是基站、终端设备、WiFi接入点(Access Point，AP)等等。传输节点开始传输后，占用的信道时间不能超过MCOT。
在NR版本15(Release 15，R15)中，每个载波最大的信道带宽(channel bandwidth)是400MHz。但是考虑到终端设备能力，终端设备支持的最大带 宽可以小于400MHz，且终端设备可以工作在多个小的带宽部分(Bandwidth Part，BWP)上。每个带宽部分对应于一个基带参数(Numerology)，带宽(Bandwidth)，频域位置(Frequency Location)。基站可以为终端设备配置多于一个BWP，基站需要告诉终端设备在哪一个BWP上工作，即激活(activate)哪一个BWP。BWP的激活去激活可以通过下行控制信令(Downlink Control Information，DCI)信令。终端设备在收到激活去激活指令后，在相应的激活的BWP上进行接收或者发送。对于时分双工(Time Division Duplexing，TDD)频段，标识(Identity，ID)或者索引(index)相同的下行(DL)BWP和上行(UL)BWP组成一个BWP对(pair)，该BWP对里的BWP中心载频一样，以减少切换时延。
在非授权频段上，基站(next generation NB，gNB)或者终端设备在激活的BWP上传输前也需要进行信道侦听，当信道为空闲时，方可传输信息。
当信道侦听只针对激活的BWP时，如果信道为忙，则gNB或者终端设备不能进行传输。但是因为终端设备可能会由基站配置多于一个BWP，其他未激活的BWP可能会空闲，因此该部分资源会被浪费。而目前网络设备和终端设备在非授权频段上对UL BWP和DL BWP理解不一致，亟待解决。

具体实施方式
下面将结合本公开实施例中的附图，对本公开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一部分实施例，而不是全部的实施例。基于本公开中的实施例，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，都属于本公开保护的范围。
本申请的说明书和权利要求书中的术语“包括”以及它的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。此外，说明书以及权利要求中使用“和/或”表示所连接对象的至少其中之一，例如A和/或B，表示包含单独A，单独B，以及A和B都存在三种情况。
在本公开实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本公开实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
本文所描述的技术不限于长期演进型(Long Time Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，并且也可用于各种无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)和其他系统。术语“系统”和“网络”常被可互换地使用。CDMA系统可实现诸如CDMA2000、通用地面无线电接入(Universal Terrestrial Radio Access，UTRA)等无线电技术。UTRA包括宽带CDMA (Wideband Code Division Multiple Access，WCDMA)和其他CDMA变体。TDMA系统可实现诸如全球移动通信系统(Global System for Mobile Communication，GSM)之类的无线电技术。OFDMA系统可实现诸如超移动宽带(Ultra-Mobile Broadband，UMB)、演进型UTRA(Evolution-UTRA，E-UTRA)、IEEE 802.11(Wi-Fi)、IEEE 802.16(WiMAX)、IEEE 802.20、Flash-OFDM等无线电技术。UTRA和E-UTRA是通用移动电信系统(Universal Mobile Telecommunications System，UMTS)的部分。LTE和更高级的LTE(如LTE-A)是使用E-UTRA的新UMTS版本。UTRA、E-UTRA、UMTS、LTE、LTE-A以及GSM在来自名为“第三代伙伴项目”(3rd Generation Partnership Project，3GPP)的组织的文献中描述。CDMA2000和UMB在来自名为“第三代伙伴项目2”(3GPP2)的组织的文献中描述。本文所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。然而，以下描述出于示例目的描述了NR系统，并且在以下大部分描述中使用NR术语，尽管这些技术也可应用于NR系统应用以外的应用。
下面结合附图介绍本公开的实施例。本公开实施例提供的信号处理方法和设备可以应用于无线通信系统中。参考图1，为本公开实施例提供的一种无线通信系统的架构示意图。如图1所示，该无线通信系统可以包括：网络设备10和终端设备，例如，终端设备记做UE1，UE1可以与网络设备10通信(传输信令或传输数据)。在实际应用中上述各个设备之间的连接可以为无线连接，为了方便直观地表示各个设备之间的连接关系，图中采用实线示意。需要说明的是，上述通信系统可以包括多个UE11，网络设备10可以与多个UE11通信。
本公开实施例提供的终端设备可以为手机、平板电脑、笔记本电脑、超级移动个人计算机(Ultra-Mobile Personal Computer，UMPC)、上网本或者个人数字助理(Personal Digital Assistant，PDA)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备等。
本公开实施例提供的网络设备10可以为基站，该基站可以为通常所用的基站，也可以为演进型基站(evolved node base station，eNB)，还可以为5G系统中的网络设备(例如，下一代基站(next generation node base station，gNB) 或发送和接收点(Transmission and Reception Point，TRP))等设备。需要说明的是，在本公开实施例中仅以5G系统中的基站(gNB)为例，但是并不限定基站的具体类型。
基站可在基站控制器的控制下与终端设备11通信，在各种示例中，基站控制器可以是核心网或某些基站的一部分。一些基站可通过回程与核心网进行控制信息或用户数据的通信。在一些示例中，这些基站中的一些可以通过回程链路直接或间接地彼此通信，回程链路可以是有线或无线通信链路。无线通信系统可支持多个载波(不同频率的波形信号)上的操作。多载波发射机能同时在这多个载波上传送经调制信号。例如，每条通信链路可以是根据各种无线电技术来调制的多载波信号。每个已调制信号可在不同的载波上发送并且可携带控制信息(例如，参考信号、控制信道等)、开销信息、数据等。
基站可经由一个或多个接入点天线与终端设备11进行无线通信。每个基站可以为各自相应的覆盖区域提供通信覆盖。接入点的覆盖区域可被划分成仅构成该覆盖区域的一部分的扇区。无线通信系统可包括不同类型的基站(例如宏基站、微基站、或微微基站)。基站也可利用不同的无线电技术，诸如蜂窝或WLAN无线电接入技术。基站可以与相同或不同的接入网或运营商部署相关联。不同基站的覆盖区域(包括相同或不同类型的基站的覆盖区域、利用相同或不同无线电技术的覆盖区域、或属于相同或不同接入网的覆盖区域)可以交叠。
无线通信系统中的通信链路可包括用于承载上行链路(Uplink，UL)传输(例如：从终端设备11到网络设备10)的上行链路，或用于承载下行链路(Downlink，DL)传输(例如：从网络设备10到终端设备11)的下行链路。UL传输还可被称为反向链路传输，而DL传输还可被称为前向链路传输。下行链路传输可以使用授权频段、非授权频段或这两者来进行。类似地，上行链路传输可以使用有授权频段、非授权频段或这两者来进行。
下面展开说明，gNB或者终端设备侦听多个BWP，根据侦听结果选择一个信道为空闲的BWP作为active BWP。这样需要终端设备去监测各个BWP上的物理下行控制信道(Physical Downlink Control Channel，PDCCH)和物理 下行共享信道(Physical Downlink Shared Channel，PDSCH)，增加了终端设备的解调难度。对应的，gNB也需要在所有配置的BWP上监测终端设备的传输，以确定终端设备传输的BWP。由于终端设备和gNB各自决定终端设备的active UL BWP和active DL BWP，还可能造成在非授权频段上UL或DL active BWP中心载频不一致，带来额外切换时延。
参见图2，本公开实施例提供了一种信号处理方法，该方法的执行主体为终端设备，具体步骤如下：
步骤201：对非授权频段中的一个或多个第一DL BWP进行PDCCH监测；
步骤202：PDCCH，得到DL BWP相关信息或UL BWP相关信息。
在本公开实施例中，该DL BWP或UL BWP相关信息可以用于直接确定接收数据的DL BWP或发送数据的UL BWP，即该接收数据的DL BWP或发送数据的UL BWP相关信息显式指示接收数据的DL BWP或发送数据的UL BWP，或者该接收数据的DL BWP或发送数据的UL BWP相关信息可以用于间接确定接收数据的DL BWP或发送数据的UL BWP，即该接收数据的DL BWP或发送数据的UL BWP相关信息隐式指示接收数据的DL BWP或发送数据的UL BWP。例如：基于接收数据的DL BWP或发送数据的UL BWP相关信息和映射关系或特定规则，推到出接收数据的DL BWP或发送数据的UL BWP。
在本公开实施例中，可选地，在步骤202中，从PDCCH中的第一指示信息，得到接收数据的DL BWP相关信息或发送数据的UL BWP相关信息，所述第一指示信息可以显式指示或隐式指示发送数据的UL BWP和/或接收数据的DL BWP，使得终端设备可以在非授权频段的一个或多个BWP上进行传输，终端设备和网络设备可以迅速接入非授权频段，且发送数据的UL BWP和接收数据的DL BWP中心载频一致。
可选地，第一指示信息可以是下行控制信息(Downlink Control Information，DCI)，例如DCI中的BWP指示(bandwidth part indicator)字段可以表示该第一指示信息。
在本公开实施例中，可选地，在图2所示的方法的基础上，该方法还可 以包括：根据UL BWP相关信息，在对应的一个或多个第一UL BWP上进行信道侦听，得到第一侦听结果；当第一侦听结果指示一个或多个第一UL BWP中存在传输信道空闲的UL BWP时，在传输信道空闲的UL BWP中选取至少一个UL BWP为激活UL BWP；在激活UL BWP上，进行上行传输。
在本公开实施例中，终端设备可以根据监测到的PDCCH，得到DL BWP相关信息或UL BWP相关信息，使得终端设备和网络设备对UL BWP和DL BWP理解保持一致，从而提高通信的可靠性和有效性。
参见图3，本公开实施例提供了另一种信号处理方法，该方法的执行主体为网络设备，具体步骤如下：
步骤301：对非授权频段下的一个或多个第一DL BWP进行信道侦听，得到第二信道侦听结果，其中终端设备监测一个或多个第一DL BWP；
例如，终端设备可以同时监测多个第一DL BWP。
步骤302：当第二信道侦听结果指示第一DL BWP中存在传输信道空闲的DL BWP时，在传输信道空闲的DL BWP中选取至少一个DL BWP为终端设备的激活DL BWP；
步骤303：在激活DL BWP上，向该终端设备发送PDCCH承载的控制信息。
在本公开实施例中，网络设备在激活DL BWP上，向终端设备发送PDCCH，该终端设备可以根据监测到的PDCCH，得到接收数据的DL BWP相关信息或发送数据的UL BWP相关信息，使得终端设备和网络设备对UL BWP和DL BWP理解保持一致，从而提高通信的可靠性和有效性。
参见图4，本公开实施例提供了又一种信号处理方法，该方法的执行主体为终端设备，具体步骤如下：
步骤401：接收主小区(Primary Cell，PCell)的PDCCH承载的控制信息；
步骤402：从PDCCH承载的控制信息得到第二指示信息，第二指示信息可以显式指示或隐式指示所述终端设备在一个或多个辅小区(Secondary Cell，SCell)的UL BWP相关信息和/或DL BWP相关信息。
在本公开实施例中，第二指示信息可以是下行控制信息，例如：DCI中 的BWP指示(bandwidth part indicator)表示该第一指示信息。
在本公开实施例中，该DL BWP或UL BWP相关信息可以用于直接确定接收数据的DL BWP或发送数据的UL BWP，即该接收数据的DL BWP或发送数据的UL BWP相关信息显式指示接收数据的DL BWP或发送数据的UL BWP，或者该接收数据的DL BWP或发送数据的UL BWP相关信息可以用于间接确定接收数据的DL BWP或发送数据的UL BWP，即该接收数据的DL BWP或发送数据的UL BWP相关信息隐式指示接收数据的DL BWP或发送数据的UL BWP。例如：基于接收数据的DL BWP或发送数据的UL BWP相关信息和映射关系或特定规则，推到出接收数据的DL BWP或发送数据的UL BWP。
例如：上述主小区工作在授权频段，辅小区工作在非授权频段。
可以理解的是，在本公开实施例中，终端设备还可以从主辅小区(Primary Secondary Cell，PScell)或者其他SCell上接收PDCCH承载的控制信息，PDCCH承载的控制信息包括第二指示信息，其中PScell和其他SCell工作在授权频段上。
在本公开实施例中，终端设备可以通过授权小区的PDCCH，得到非授权小区的UL BWP相关信息和/或DL BWP相关信息，使得终端设备和网络设备对UL BWP和DL BWP理解保持一致，从而提高通信的可靠性和有效性。

步骤501：向终端设备发送PCell的PDCCH承载的控制信息，所述PDCCH承载的控制信息包括第二指示信息，所述第二指示信息可以显式指示或隐式指示所述终端设备在一个或多个SCell的UL BWP相关信息和/或DL BWP相关信息。
在本公开实施例中，第二指示信息可以是下行控制信息，例如：DCI中的BWP指示(bandwidth part indicator)字段表示该第一指示信息。
可以理解的是，图5所示实施例中的UL BWP相关信息和/或DL BWP相关信息的描述可参见图4所示的步骤401中的描述。
例如：上述主小区工作在授权频段，辅小区工作在非授权频段。
可以理解的是，在本公开实施例中，网络设备可以通过主辅小区(Primary Secondary Cell，PScell)或者其他SCell上发送PDCCH承载的控制信息，PDCCH承载的控制信息包括第二指示信息，其中PScell和其他SCell工作在授权频段上。
在本公开实施例中，第二指示信息可以是下行控制信息，例如：DCI中的BWP指示(bandwidth part indicator)表示该第一指示信息。
在本公开实施例中，网络设备向终端设备发送主小区的PDCCH，终端设备可以通过主小区的PDCCH，得到辅小区的UL BWP相关信息和/或DL BWP相关信息，使得终端设备和网络设备对UL BWP和DL BWP理解保持一致，，从而提高通信的可靠性和有效性。
参见图6，本公开实施例提供了又一种信号处理方法，该方法的执行主体为终端设备，具体步骤如下：
步骤601：从网络设备接收组公共PDCCH(Group Common PDCCH，GC-PDCCH)承载的控制信息，所述组公共PDCCH承载的控制信息可以显式指示或隐式指示所述终端设备进行UL BWP和/或DL BWP切换。
在本公开实施例中，可选地，组公共PDCCH承载的控制信息可以显式指示或隐式指示终端设备根据切换规则进行UL BWP和/或DL BWP切换，该切换规则可以包括以下至少一项：
根据BWP的标识进行DL BWP和/或UL BWP切换；

根据所述终端设备在UL BWP的信道接入率和所述网络设备在DLBWP的信道接入率进行DL BWP和/或UL BWP切换。
在本公开实施例中，可选地，切换规则可以由终端设备和网络设备预先约定，或者由协议规定。
在本公开实施例中，网络设备可以通过组公共PDCCH通知终端设备进行UL BWP和/或DL BWP切换，使得终端设备和网络设备对UL BWP和DL BWP理解保持一致，从而提高通信的可靠性和有效性。
参见图7，本公开实施例提供了又一种信号处理方法，该方法的执行主体为网络设备，具体步骤如下：
步骤701：向终端设备发送组公共PDCCH承载的控制信息，组公共PDCCH承载的控制信息可以显式指示或隐式指示终端设备进行UL BWP和/或DL BWP切换。
在本公开实施例中，可选地，组公共PDCCH承载的控制信息可以显式指示或隐式指示终端设备根据切换规则进行UL BWP和/或DL BWP切换，切换规则可以包括以下至少一项：
根据BWP的标识进行DL BWP和/或UL BWP切换；
根据所述终端设备在UL BWP的RSSI和所述网络设备在DL BWP的RSSI进行DL BWP和/或UL BWP切换；以及
根据所述终端设备在UL BWP的信道接入率和所述网络设备在DL BWP的信道接入率进行DL BWP和/或UL BWP切换。
在本公开实施例中，可选地，切换规则可以由所述终端设备和网络设备预先约定，或者由协议规定。
在本公开实施例中，网络设备可以通过组公共PDCCH通知终端设备进行UL BWP和/或DL BWP切换，使得终端设备和网络设备对UL BWP和DL BWP理解保持一致，从而提高通信的可靠性和有效性。
根据本公开所提供的一些实施例，当终端设备可以同时检测多个DL BWP的PDCCH时，终端设备在多个非授权频段的DL BWP的PDCCH监测时机(monitor occasion)监测PDCCH。对于下行传输，gNB在所有终端设备可以同时监测的DL BWP上进行侦听，当侦听到信道为空闲(idle)时，gNB选择一个或者多个信道为空闲的DL BWP发送PDCCH，并在其中一个或者多个DL BWP上发送PDSCH数据。
当终端设备同时检测多个DL BWP的PDCCH时，终端设备在同一时刻只期待收到一个PDCCH(一个DL grant和/或一个UL grant)，若终端设备收到多个PDCCH(多个DL grant和/或多个UL grant)，则为错误情况(error case)。
此时gNB在所有终端设备可以同时监测的DL BWP上进行侦听，当侦听 到信道为空闲时，可选地，gNB选择一个DL BWP发送PDCCH，gNB可以在该DL BWP发送PDSCH数据。DCI中可以包含或者不包含带宽部分指示(bandwidth part indicator)指示数据所在的DL BWP。此外，gNB也可以在多个DL BWP上发送PDCCH。当DCI中不包含带宽部分指示时，隐式地指示数据传输所在的DL BWP与PDCCH传输所在的DL BWP相同。
当终端设备同时检测多个DL BWP的PDCCH时，终端设备在同一时刻可以期待收到多个PDCCH(多个DL grant和/或多个UL grant)。
此时gNB在所有终端设备可以同时监测的DL BWP上进行侦听，当侦听到信道为空闲时，gNB可选择信道为空闲的多个DL BWP发送PDCCH和PDSCH数据。DCI中可以包含或者不包含bandwidth part indicator指示数据所在的DL BWP。
若每个DL BWP都是自调度(self-scheduling)，即每个DL BWP上的PDCCH调度自己所在BWP上的PDSCH。则每个PDCCH里面的bandwidth part indicator指示该PDCCH所在的DL BWP的索引(index)或者BWP pair index。此外，为了节省信令，DCI中也可以不包含bandwidth part indicator。即隐式地指示PDSCH和PDCCH在相同的DL BWP上。如果允许跨BWP调度(cross-BWP scheduling)，即每个DL BWP可以调度其他DL BWP上的PDSCH，则每个PDCCH里面的bandwidth part indicator指示了数据所在的BWP。bandwidth part indicator可以指示BWP的index或者BWP pair的index。
根据本公开所提供的一些实施例，对于上行传输，gNB在所有终端设备可以同时监测的DL BWP上进行侦听，当侦听到信道为空闲时，gNB选择一个或者多个信道为空闲的DL BWP发送PDCCH(UL grant)，指示终端设备在一个或者多个UL BWP上发送PUSCH数据。
终端设备在多个DL BWP上监测PDCCH，根据监测检测到的PDCCH得到UL grant中的上行数据传输的UL BWP的信息。终端设备在对应的UL BWP上做LBT，当检测到信道为空闲时，按照PDCCH中的UL grant指示进行上行数据传输。
例如：终端设备同时在DL BWP1和DL BWP2上监测对应的PDCCH，且在DL BWP1上检测到PDCCH，该PDCCH指示UE在UL BWP1上进行 上行传输。终端设备在UL BWP1上进行LBT，当侦听的UL BWP1为空闲时，则在UL BWP1上传输上行数据。若gNB长时间没有收到数据，则会在PDCCH中指示终端设备在新的UL BWP上传输数据，也就是进行BWP切换。
若UE在DL BWP1和DL BWP2上分别检测到了PDCCH，也就是接收到了两个UL grant。则UE分别根据这两个UL grant中的信息在对应的UL BWP上进行侦听，当侦听到信道为空时，在对应的UL BWP上按照UL grant指示分别进行传输。
根据本公开所提供的一些实施例，当终端设备只能在一个active BWP上接收或者发送时，gNB和终端设备一起切换BWP。对于licensed-assisted传输，可以在授权小区(licensed cell)指示终端设备在非授权小区(unlicensed cell)上的BWP相关信息。
例如：在主小区(Primary Cell，PCell)上指示终端设备在辅小区(Secondary Cell，SCell)上的BWP相关信息；或者，在PScell上指示终端设备在辅小区上的BWP相关信息，PScell工作在授权频段上，辅小区工作在非授权频段是行；或者，在第二辅小区(其他辅小区)上指示终端在第一辅小区上的BWP相关信息，其中第二辅小区工作在授权频段上，第一辅小区工作在非授权频段上。
例如：在PDCCH中增加一个新的bandwidth part indicator，指示一个或者多个非授权频段SCell的BWP相关信息。终端设备根据bandwidth part indicator在对应的unlicensed BWP上进行接收或者发送。
此外，当信道接入率低的时候，即gNB侦听到信道总是为忙，或者gNB长时间没有收到终端设备的传输，gNB可以通过组公共PDCCH(Group Common PDCCH，GC-PDCCH)通知终端设备进行BWP切换。可以在GC-PDCCH中增加一个域(field)，指示终端设备需要进行BWP切换。gNB和终端设备可以按照BWP index或者其他规则顺序切换BWP。例如：gNB可以广播gNB在unlicensed cell上的每个(per)BWP RSSI或者per BWP的信道接入率。终端设备则上报自己在unlicensed cell上的per BWP RSSI或者per BWP的信道接入率。gNB和终端设备先选择终端设备RSSI低于某一门限的多个BWP，然后在这些BWP中选出gNB RSSI最低的BWP进行传输。同 理，也可以先选择gNB RSSI低于某一门限的多个BWP，然后在这些BWP中选出终端设备RSSI最低的BWP进行传输。此外，可以先选择DL BWP，然后得到对应的UL BWP。或者，也可以先选择UL BWP，得到对应的DL BWP。
对于stand alone的情况，gNB每次固定在一个DL BWP上发送，若信道接入率低，则会在下次接入时通知终端设备切换DL BWP。终端设备切换后，gNB在新的DL BWP上发送。同理，若gNB长时间未能接收到终端设备的上行传输，则会指示终端设备切换UL BWP。对于TDD频段，DL BWP会和UL BWP同时切换。
