Description

数据发送、 接收方法、 基站和用户设备 技术领域
本发明的实施例涉及通信系统, 尤其是涉及一种数据发送、 接收方法、 基站和用户设备。 背景技术
频谱资源是无线通信的基础, 非授权 ( unlicensed )频谱资源要大于授权 频谱资源。 目前, 未授权频谱上使用的主要技术是无线保真 (Wireless Fidelity, WiFi ),但是 WiFi在移动性、安全性、服务质量( Quality of Service, QoS )、以及同时处理多用户调度方面存在缺陷,因此,将长期演进( Long-term Evolution, LTE )设备应用在非授权频谱, 不仅可以有效利用非授权频谱资 源,还可以提供更为有效的无线接入、满足日益增长的移动宽带服务的需求。
由于非授权频谱上对无线通信系统和运营商使用没有约束, 非授权频谱 为共享频谱, 即存在多种通信系统的多个运营商都想要占用相同频谱的情 况。 无线通信设备在未授权频谱上使用时需要遵循特定的法规规则, 例如欧 洲电信标准协会 ( European Telecommunications Standards Institute , ETSI )发 布的 ETSI EN 301 893中对未授权频谱使用时规定了先听后说( Listen Before Talk, LBT )、 信道带宽占用需求等规则。 根据 LBT规则, 设备在使用信道 之前, 首先监听信道是否空闲, 如果信道空闲则可以使用该非授权频谱上的 信道。
对于长期演进 ( Long Term Evolution, LTE ) 通信系统, 基站 ( evolvedNodeB, eNB )和用户设备 ( User Equipment, UE )进行上行数据 的传输时, 基站需要发送控制信息给用户设备, 用户设备则根据所述控制 信息向基站发送数据以完成上行数据的传输。 载波聚合 ( Carrier Aggregation, CA )技术是多个成员载波 ( Component Carrier, CC )的资源 同时调度给一个用户设备使用, 对于同一个 CC上数据传输的控制信息可 以通过同载波调度 ( Same-CC Scheduling, SCS ) 或者通过跨载波调度 ( Cross-CC Scheduling, CCS )进行传输。 对于跨载波调度而言, 用户设备 需要对不同的成员载波进行盲检测, 这会增加用户设备的功耗、 盲检测复 杂度以及盲检测时间。 在现有技术中,控制信息的获取随着载波聚合的成员载波数量的增加而 变得异常复杂, 这会导致基站或用户设备利用控制信息发送或者接收数据 的效率降低。 发明内容

本发明实施例基于上述系统架构, 需要说明的是, 在不冲突的情况下, 图 2为本发明实施例提供的数据传输方法, 其步骤包括:
步骤 21,基站向用户设备发送第一指示信息。 其中, 所述第一指示信息 用于指示属于调度载波集合的各个载波和所述属于调度载波集合的各个载 波的优先级顺序, 所述调度载波集合是所述基站配置的可用于发送第一控制 信息的载波的集合, 所述第一控制信息是在第二载波发送或接收第一数据的 控制信息。 所述调度载波集合中的各个载波都是传输所述第一控制信息的备 选载波, 即所述调度载波集合中的任意一个载波都有可能用于传输所述第一 控制信息。 所述优先级顺序为所述调度载波集合中的各个载波用于传输所述 第一控制信息的优先级顺序。
步骤 22,所述基站根据所述属于调度载波集合的各个载波和所述属于调 度载波集合的各个载波的优先级顺序按照由高到低的顺序确定待定载波。基 站根据属于调度载波集合的各个载波的优先级顺序按照由高到低确定各个 载波是否满足预设条件的判断顺序。
步骤 23, 所述基站根据所述待定载波和预设条件确定第一载波。 其中, 所述第一载波为所述调度载波集合中满足所述预设条件的载波中优先级最 高的载波, 所述第一载波用于传输所述第一控制信息。 可选的, 所述基站根 据所述属于调度载波集合的各个载波、所述属于调度载波集合的各个载波的 优先级顺序确定待定载波,再根据待定载波和预设条件确定第一载波。例如, 基站按照属于调度载波集合中各个载波优先级的由高到低的顺序依次判断 所述调度载波集合中的载波是否满足所述预设条件, 例如, 基站先判断所述 调度载波集合中优先级最高的载波是否满足所述预设条件, 此时优先级最高 的载波为待定载波, 如果满足, 则所述优先级最高的载波为所述第一载波, 如果不满足, 则判断所述调度载波集合中优先级次高的载波是否满足所述预 设条件, 此时优先级次高的载波为待定载波, 如果满足, 则所述优先级次高 的载波为所述第一载波, 如果不满足, 按照优先级由高到低的顺序依次判断 各个载波是否满足所述预设条件。 可选的, 所述基站在所述第二载波上能够 发送信号的起始时刻判断所述待定载波是否满足所述预设条件, 其中, 所述 基站在所述第二载波上能够发送信号的起始时刻可以为基站在第二载波上 能够发送数据或者控制信息的起始时刻, 所述基站可以在不同的子帧根据所 述待定载波和预设条件确定所述第一载波, 因此, 所述第一载波在不同的子 帧可以为不同的载波。
在本发明可选的实施例中, 步骤 22 可以由步骤 22' 代替, 而步骤 23 可以由步骤 23' 代替, 在本可选的实施例中, 图 2提供的数据传输方法, 其 步骤包括: 步骤 21、 步骤 22' 、 步骤 23' 、 步骤 24以及步骤 25。
步骤 11' 为所述基站根据所述属于调度载波集合的各个载波确定待定 载波。 虽然步骤 21 的第一指示信息中包含属于调度载波集合的各个载波的 优先级顺序, 但是, 步骤 22' 中, 基站只是随机的确定待定载波, 而没有根 据所述属于调度载波集合的各个载波的优先级顺序来确定待定载波。
步骤 23' 为所述基站根据所述待定载波、预设条件和所述属于调度载波 集合的各个载波的优先级顺序确定第一载波。 在可选的实施例中, 所述基站 确定满足所述预设条件的待定载波为备选载波集合, 然后, 所述基站根据所 述备选载波集合和所述属于调度载波集合的各个载波的优先级顺序确定属 于所述备选载波集合中优先级顺序最高的载波为第一载波。
其中, 所述预设条件包括以下条件中的至少一个:
条件一,在所述待定载波上发送所述第一控制信息的资源属于所述待定 载波上预配置的用于发送控制信息的资源, 或者, 条件二, 所述待定载波为 非共享频谱上的载波或所述待定载波为共享频谱上的载波且所述待定载波 在所述第一控制信息的资源上处于开启状态, 所述开启状态为所述基站能够 在所述待定载波上传输数据, 或者, 条件三, 所述待定载波在所述第一控制 信息的资源上处于非连续接收( Discontinuous Reception, DRX )的非激活期。 可选的, 预设条件可以为上述三个条件中的任意一个, 或者任意两个, 或者 预设条件为上述三个条件都需要被满足。
所述在所述待定载波上发送所述第一控制信息的资源指的是第一控制 信息在所述待定载波上发送时可以占用的资源, 即所述待定载波上被用于发 送所述第一控制信息的资源。
可选的,所述待定载波为非共享频谱上的载波或所述待定载波为共享频 谱上的载波且所述待定载波在所述第一控制信息的资源上处于开启状态。 所 述开启状态为基站根据 LBT规则对共享频谱进行监听并监听到的结果为所 述共享频谱空闲且所述基站能够在所述共享频谱上传输数据。 否则, 如果基 站根据 LBT规则对共享频谱进行监听并监听到的结果为所述共享频谱被占 用, 则所述基站不能在所述共享频谱上传输数据, 此时所述待定载波处于关 闭状态。
可选的, 所述待定载波在所述第一控制信息的资源上处于非连续接收 ( Discontinuous Reception, DRX ) 的非激活期。 只有在非连续接收 DRX的 非激活期, 所述待定载波上的资源才能用来发送控制信息, 否则在非连续接 收 DRX的激活期, 所述待定载波上的资源不能用来发送控制信息。 可选的,在所述待定载波上发送所述第一控制信息的资源属于所述待定 载波上预配置的用于发送控制信息的资源。 所述待定载波上预配置的资源可 以是以下资源中的至少一种:
( 1 )所述预配置的资源为所述待定载波中的下行子帧或下行传输期间 的资源。 所述基站根据所述待定载波在发送所述第一控制信息的子帧是否为 下行子帧或者为下行传输期间的资源,确定所述待定载波是否满足所述预设 条件。 如果是, 则确定所述待定载波满足所述预设条件; 如果否, 则确定所 述待定载波不满足所述预设条件。
( 2 )所述预配置的资源为所述待定载波上某一下行子帧上的物理下行 控制信道 ( Physical Downlink Control Channel, PDCCH ) 的资源。 即所述下 行子帧的前 1~N (对于系统带宽 A > 10, N=3;对于系统带宽 A ≤ 10, N=4 ) 个 OFDM符号。所述 PDCCH的资源由所述下行子帧上的 PCFICH信道通知 给用户设备。 所述基站根据所述待定载波在发送所述第一控制信息的子帧上 的资源是否为所述 PDCCH中的资源确定所述待定载波是否满足所述预设条 件。 如果是, 则确定所述待定载波满足所述预设条件; 如果否, 则确定所述 待定载波不满足所述预设条件。 例如, 如果在所述待定载波上发送所述第一 控制信息的资源从第 M ( M〉l )个 OFDM符号开始, 则在所述待定载波上 发送所述第一控制信息的资源不属于所述待定载波上预配置的用于发送控 制信息的资源,所述待定载波不满足所述预设条件。如果在所述待定载波上发 送所述第一控制信息的资源从第 1个 OFDM符号开始, 则在所述待定载波 上发送所述第一控制信息的资源属于所述待定载波上预配置的用于发送控 制信息的资源,所述待定载波满足所述预设条件。
(3) 所述预配置的资源为所述基站为接收所述第一控制信息的用户设 备配置的在所述待定载波上的增强的物理下行控制信道(Enhanced Physical Downlink Control Channel, E-PDCCH )的资源。 所述 E-PDCCH资源在一个 子帧中时域上的起始位置由 PCFICH或者由所述基站通过高层信令通知给所 述用户设备, 所述 E-PDCCH资源在一个子帧中的频域位置由所述基站通过 高层信令通知给所述用户设备。 所述基站根据所述待定载波在发送所述第一 控制信息的子帧上的资源是否为所述 E-PDCCH中的资源确定所述待定载波 是否满足所述预设条件。 如果是, 则确定所述待定载波满足所述预设条件; 如果否, 则确定所述待定载波不满足所述预设条件。 例如, 如果在所述待定 载波上预配置的 E-PDCCH的资源从第 3个 OFDM符号开始,而所述发送所 述第一控制信息的资源从第 M ( M〉3 )个 OFDM符号开始, 则在所述待定 载波上发送所述第一控制信息的资源不属于所述待定载波上预配置的用于 发送控制信息的资源,所述待定载波不满足所述预设条件。如果在所述待定载 波上发送所述第一控制信息的资源从第 3个 OFDM符号开始, 则在所述待 定载波上发送所述第一控制信息的资源属于所述待定载波上预配置的用于 发送控制信息的资源,所述待定载波满足所述预设条件。
步骤 24, 所述基站在所述第一载波发送所述第一控制信息。

通过本发明实施例,基站根据待定载波和预设条件、或者根据待定载波、 预设条件和所述属于调度载波集合的各个载波的优先级顺序确定第一载波, 所述待定载波是所述基站根据所述属于调度载波集合的各个载波和所述属 于调度载波集合的各个载波的优先级顺序按照由高到低的顺序确定的或者 是由所述基站根据所述属于调度载波集合的各个载波确定的,基站判断属于 所述调度载波集合的载波是否满足预设条件时会考虑调度载波集合中各个 载波的优先级顺序, 由此来确定用于传输控制信息的第一载波, 基站将会在 此第一载波发送控制信息, 而用户设备也会在此第一载波上接收控制信息, 大大降低了基站发送控制信息以及用户设备接收控制信息在多个配置的载 波上的任意一个载波上发送带来的复杂度,提高了基站或用户设备利用控制 信息发送或者接收数据的效率。
在可选的实施例中, 所述待定载波为所述属于调度载波集合的各个载波 中优先级最高的载波; 所述基站根据所述待定载波和预设条件确定第一载波 包括: 所述基站确定所述待定载波满足所述预设条件, 所述基站确定所述待 定载波为所述第一载波。

在可选的实施例中, 基站根据所述待定载波和预设条件确定第一载波, 基站根据所述属于调度载波集合的各个载波从高到低的优先级顺序判断所 述第一指示信息中包含的属于调度载波集合的各个载波是否满足所述的预 设条件, 例如, 首先判断优先级最高的载波是否满足所述预设条件, 如果满 足, 则优先级最高的载波为所述第一载波, 如果不满足, 其次判断优先级次 高的载波是否满足所述预设条件, 如果满足, 则优先级次高的载波为所述第 一载波, 如果不满足, 以此类推, 直到某一个载波满足所述预设条件, 则将 此满足所述预设条件的载波作为所述第一载波。
在可选的实施例中, 在所述基站向用户设备发送第一指示信息之前, 所 述基站确定属于所述调度载波集合的各个载波和属于所述调度载波集合的 各个载波的优先级顺序。

图 6为本发明实施例提供的一种数据发送、 接收方法, 具体步骤如下: 步骤 61,基站确定属于所述调度载波集合的各个载波和属于所述调度载 波集合的各个载波的优先级顺序。
步骤 62, 基站向用户设备发送第一指示信息。
所述调度载波集合是所述基站配置的可用于发送第一控制信息的载波 的集合, 所述第一控制信息是在第二载波发送或接收第一数据的控制信息。
例如,为用户设备配置的调度载波集合为载波 1( Cell-1 )、载波 2( Cell-2 )、 载波 3 ( Cell-3 ), 即调度载波集合中含有 3个载波, 分别为 Cell-1、 Cell-2 以及 Cell-3, 这只是对调度载波集合的举例, 并不是对其含有的载波或者含 有的载波的数量的限制。 其中, Cell-1的载波为非共享频谱上的载波, Cell-2 和 Cell-3的载波为共享频谱上的载波。 对于利用 Cell-2进行第一数据发送或者接收的情况,基站向用户设备发 送第一指示信息。所述第一指示信息用于指示 Cell-1和 Cell-2作为调度载波 集合, 即调度载波集合包含 Cell-1和 Cell-2, 优先级顺序为 Cell-1 > Cell-2。
对于利用 Cell-3进行第一数据发送或者接收的情况,基站向用户设备发 送第一指示信息。 所述第一指示信息用于指示 Cell-1、 Cell-2, Cell-3作为调 度载波集合, 即调度载波集合包含 Cell-1、 Cell-2和 Cell-3, 优先级顺序为 Cell-2 > Cell-1 > Cell-3。
步骤 63,所述基站根据所述第一指示信息和预设条件确定第一载波。即, 所述基站根据属于调度载波集合的各个载波、所述属于调度载波集合的各个 载波的优先级顺序和预设条件确定第一载波。 具体的, 基站可以先根据所述 属于调度载波集合的各个载波和所述属于调度载波集合的各个载波的优先 级顺序按照由高到低的顺序确定待定载波, 然后, 所述基站根据所述待定载 波和预设条件确定第一载波。 或者, 基站可以根据所述属于调度载波集合的 各个载波确定待定载波, 然后, 所述基站根据所述待定载波、 预设条件和所 述属于调度载波集合的各个载波的优先级顺序确定第一载波。
其中, 所述第一载波为所述调度载波集合中满足所述预设条件的载波中 优先级最高的载波, 所述第一载波用于传输所述第一控制信息。 可选的, 所 述基站根据所述属于调度载波集合的各个载波、所述属于调度载波集合的各 个载波的优先级顺序和预设条件确定第一载波。 例如, 基站按照属于调度载 波集合中各个载波优先级的由高到低的顺序依次判断所述调度载波集合中 的载波是否满足所述预设条件, 例如, 基站先判断所述调度载波集合中优先 级最高的载波是否满足所述预设条件, 此时优先级最高的载波为所述待定载 波, 如果满足, 则所述优先级最高的载波为所述第一载波, 如果不满足, 则 判断所述调度载波集合中优先级次高的载波是否满足所述预设条件,此时优 先级次高的载波为所述待定载波, 如果满足, 则所述优先级次高的载波为所 述第一载波, 如果不满足, 按照优先级由高到低的顺序依次判断各个载波是 否满足所述预设条件。
其中, 所述预设条件包括以下条件中的至少一个。 可选的, 预设条件可 以为上述三个条件中的任意一个, 或者任意两个, 或者预设条件为以下三个 条件都需要被满足。 在所述预设条件中, 所述在所述待定载波上发送所述第 一控制信息的资源指的是第一控制信息在所述待定载波上发送时可以占用 的资源。
条件一: 所述待定载波为非共享频谱上的载波, 或者所述待定载波为共 享频谱上的载波且所述待定载波在所述第一控制信息的资源上处于开启状 态。 所述开启状态为基站根据 LBT规则对共享频谱进行监听并监听到的结 果为所述共享频谱空闲且所述基站能够在所述共享频谱上传输数据。 否则, 如果基站根据 LBT规则对共享频谱进行监听并监听到的结果为所述共享频 语被占用, 则所述基站不能在所述共享频谱上传输数据, 此时所述待定载波 处于关闭状态。
条件二: 所述待定载波在所述第一控制信息的资源上处于非连续接收 ( Discontinuous Reception, DRX ) 的非激活期。 只有在非连续接收 DRX的 非激活期, 所述待定载波上的资源才能用来发送控制信息, 否则在非连续接 收 DRX的激活期, 所述待定载波上的资源不能用来发送控制信息。
条件三: 在所述待定载波上发送所述第一控制信息的资源属于所述待定 载波上预配置的用于发送控制信息的资源。 所述待定载波上预配置的资源可 以是以下资源中的至少一种:
( 1 )所述预配置的资源为所述待定载波中的下行子帧或下行传输期间 的资源。 所述基站根据所述待定载波在发送所述第一控制信息的子帧是否为 下行子帧或者为下行传输期间的资源,确定所述待定载波是否满足所述预设 条件。 如果是, 则确定所述待定载波满足所述预设条件; 如果否, 则确定所 述待定载波不满足所述预设条件。
( 2 )所述预配置的资源为所述待定载波上某一下行子帧上的物理下行 控制信道 ( Physical Downlink Control Channel, PDCCH ) 的资源。 即所述下 行子帧的前 1~N (对于系统带宽 A > 10, N=3;对于系统带宽 A ≤ 10, N=4 ) 个 OFDM符号。所述 PDCCH的资源由所述下行子帧上的 PCFICH信道通知 给用户设备。 所述基站根据所述待定载波在发送所述第一控制信息的子帧上 的资源是否为所述 PDCCH中的资源确定所述待定载波是否满足所述预设条 件。 如果是, 则确定所述待定载波满足所述预设条件; 如果否, 则确定所述 待定载波不满足所述预设条件。 例如, 如果在所述待定载波上发送所述第一 控制信息的资源从第 ( N!>1 )个 OFDM符号开始, 则在所述待定载波上 发送所述第一控制信息的资源不属于所述待定载波上预配置的用于发送控 制信息的资源,所述待定载波不满足所述预设条件。如果在所述待定载波上发 送所述第一控制信息的资源从第 1个 OFDM符号开始, 则在所述待定载波 上发送所述第一控制信息的资源属于所述待定载波上预配置的用于发送控 制信息的资源,所述待定载波满足所述预设条件。
(3) 所述预配置的资源为所述基站为接收所述第一控制信息的用户设 备配置的在所述待定载波上的增强的物理下行控制信道(Enhanced Physical Downlink Control Channel, E-PDCCH )的资源。 所述 E-PDCCH资源在一个 子帧中时域上的起始位置由 PCFICH或者由所述基站通过高层信令通知给所 述用户设备, 所述 E-PDCCH资源在一个子帧中的频域位置由所述基站通过 高层信令通知给所述用户设备。 所述基站根据所述待定载波在发送所述第一 控制信息的子帧上的资源是否为所述 E-PDCCH中的资源确定所述待定载波 是否满足所述预设条件。 如果是, 则确定所述待定载波满足所述预设条件; 如果否, 则确定所述待定载波不满足所述预设条件。 例如, 如果在所述待定 载波上预配置的 E-PDCCH的资源从第 3个 OFDM符号开始,而所述发送所 述第一控制信息的资源从第 M ( M〉3 )个 OFDM符号开始, 则在所述待定 载波上发送所述第一控制信息的资源不属于所述待定载波上预配置的用于 发送控制信息的资源,所述待定载波不满足所述预设条件。如果在所述待定载 波上发送所述第一控制信息的资源从第 3个 OFDM符号开始, 则在所述待 定载波上发送所述第一控制信息的资源属于所述待定载波上预配置的用于 发送控制信息的资源,所述待定载波满足所述预设条件。
具体如图 7所示, 图 7实施例以预设条件为同时满足条件一、 条件二和 条件三为例进行说明, 应当理解这不是对本发明实施例的限制。
对于利用 Cell-2接收或发送第一数据的情况:
在子帧 n, 由于 Cell-2的载波为共享频谱上的载波,基站根据 LBT规则 对共享频谱进行监听并监听到在子帧 n的第 6个 OFDM符号开始共享频谱 空闲, 能够占用共享频语发送信号。 此时在子帧 n中发送第一数据的第一控 制信息的资源为子帧 n的第 k ( k≥5 )个 OFDM符号以后的资源。 该步骤所 述基站根据所述第一指示信息和预设条件确定第一载波, 具体为: 根据第一 指示信息所指示的调度载波集合为 Cell-1、 Cell-2, 优先级顺序为 Cell-1 > Cell-20 基站首先判断优先级最高的 Cell-1是否满足预设条件。 第一个条件 和第二个条件分别是 "所述待定载波为非共享频谱上的载波, 或者所述待定 载波为共享频谱上的载波且所述待定载波在所述第一控制信息的资源上处 于开启状态" 和 "所述待定载波在所述第一控制信息的资源上处于非连续接 收(Discontinuous Reception, DRX ) 的非激活期", 由于 Cell-1是非共享频 谱上的载波, 满足第一个条件, 在 Cell-1处于 DRX非激活期的阶段, 也满 足第二个条件。 第三个条件是 "在所述待定载波上发送所述第一控制信息的 资源属于所述待定载波上预配置的用于发送控制信息的资源"。 由于 Cell-1 是非共享频谱上的载波, Cell-1 上预配置的资源可以是从该子帧第 1 个 OFDM符号开始的 PDCCH资源,或者是从该子帧第 M(M<4)个 OFDM符号 开始的 E-PDCCH资源。 由于在子帧 n中发送第一数据的第一控制信息的资 源为子帧 n的第 k( k > 5 )个 OFDM符号以后的资源,而 PDCCH和 E-PDCCH 中用于发送控制信息的资源是分别分布在 PDCCH和 E-PDCCH的资源的各 个 OFDM符号中, 因此在 Cell-1上发送所述第一控制信息的时机已经错过, 即在所述第 k个 OFDM符号基站已经错过了可以发送所述第一控制信息的 PDCCH资源或者 E-PDCCH资源。 即 Cell-1不满足第三个条件, 不能作为 第一载波。 然后根据第一指示信息所指示的调度载波集合为 Cell-1、 Cell-2, 优先级顺序为 Cell-1 > Cell-2,基站再判断优先级次高的 Cell-2是否满足预设 条件。 第一个条件是 "所述待定载波为非共享频谱上的载波, 或者所述待定 载波为共享频谱上的载波且所述待定载波在所述第一控制信息的资源上处 于开启状态", 这是由于 Cell-2能够从子帧 n的第 k ( ≥5 )个 OFDM符号 开始占用共享信道发送数据, 即从第 k个 OFDM符号开始 Cell-2处于开启 状态, 因此, Cell-2满足第一条件。 第二个条件是 "所述待定载波在所述第 一控制信息的资源上处于非连续接收(Discontinuous Reception, DRX )的非 激活期"。 在 Cell-2处于 DRX非激活期的阶段满足第二个条件。 第三个条件 "在所述待定载波上发送所述第一控制信息的资源属于所述待定载波上预 配置的用于发送控制信息的资源"。 由于 Cell-2是共享频谱上的载波, Cell-2 上预配置的用于发送控制信息的资源可以是该子帧结束前 N2 ( N2≤3 )个 OFDM符号的资源,因此在 Cell-2上预配置的用于发送控制信息的资源能够 作为在 Cell-2上发送所述第一控制信息的资源。即 Cell-2也满足第三个条件, 因此基站确定在子帧 n上 Cell-2为第一载波。 在子帧 n+l, 由于 Cell-2的载波为共享频谱上的载波,基站根据 LBT规 则确定在子帧 n+1能够占用共享频语发送信号。此时在子帧 n+1中发送第一 数据的第一控制信息的资源为子帧 n+1的第 1个 OFDM符号开始或者第 1 个 OFDM符号以后的资源。 该步骤所述基站根据所述第一指示信息和预设 条件确定第一载波, 具体为: 根据第一指示信息所指示的调度载波集合为 Cell-1 , Cell-2, 优先级顺序为 Cell-1 > Cell-2。 基站首先判断优先级最高的 Cell-1是否满足预设条件。 第一个条件和第二个条件分别是 "所述待定载波 为非共享频谱上的载波, 或者所述待定载波为共享频谱上的载波且所述待定 载波在所述第一控制信息的资源上处于开启状态"和 "所述待定载波在所述 第一控制信息的资源上处于非连续接收(Discontinuous Reception, DRX )的 非激活期", 由于 Cell-1是非共享频谱上的载波, 满足第一个条件, 在 Cell-1 处于 DRX非激活期的阶段, 也满足第二个条件。 第三个条件是 "在所述待 定载波上发送所述第一控制信息的资源属于所述待定载波上预配置的用于 发送控制信息的资源"。 由于 Cell-1是非共享频谱上的载波, Cell-1上预配置 的资源可以是从该子帧第 1个 OFDM符号开始的 PDCCH资源,或者是从该 子帧第 M(M<4)个 OFDM符号开始的 E-PDCCH资源。 由于在子帧 n中发送 第一数据的第一控制信息的资源为子帧 n+1的第 1个 OFDM符号以后的资 源, 因此在 Cell-1上预配置的用于发送控制信息的资源能够作为在 Cell-1上 发送所述第一控制信息的资源。 即 Cell-1满足第三个条件, 可以作为第一载 波。 因此基站确定在子帧 n+1上 Cell-2为第一载波。
对于利用 Cell-3发送或接收第一数据的情况, 如图 7 所示:
在子帧 n, 由于 Cell-3的载波为共享频谱上的载波,基站根据 LBT规则 确定子帧 n的第 1个 OFDM符号开始共享频谱空闲, 能够占用共享频语发 送信号。此时在子帧 n中发送第一数据的第一控制信息的资源为子帧 n的第 1个 OFDM符号开始或者第 1个 OFDM符号以后的资源。 这里以在子帧 n 中发送第一数据的第一控制信息的资源为子帧 n的第 1个 OFDM符号开始 的资源为例说明。该步骤所述基站根据所述第一指示信息和预设条件确定第 一载波,具体为:根据第一指示信息所指示的调度载波集合为 Cell-1、 Cell-2, Cell-3 , 优先级顺序为 Cell-2 > Cell-1 > Cell-3。 基站首先判断优先级最高的 Cell-2是否满足预设条件。 第一个条件是 "所述待定载波为非共享频语上的 载波, 或者所述待定载波为共享频谱上的载波且所述待定载波在所述第一控 制信息的资源上处于开启状态", 由于 Cell-2是共享频谱上的载波, 基站根 据 LBT规则, Cell-2在子帧 n的第 1个 OFDM符号不能占用共享频谱的资 源。 因此, 如果在子帧 n中发送第一数据的第一控制信息的资源为子帧 n的 第 1个 OFDM符号开始的资源, 由于 Cell-2在在子帧 n的第 1个 OFDM符 号处于关闭状态, 因此 Cell-2不满足第一个条件, 不能作为第一载波。 然后 根据第一指示信息所指示的调度载波集合为 Cell-1、 Cell-2, Cell-3 , 优先级 顺序为 Cell-2 > Cell-1 > Cell-3 , 基站再判断优先级次高的 Cell-1是否满足预 设条件。 第一个条件和第二个条件分别是 "所述待定载波为非共享频谱上的 载波, 或者所述待定载波为共享频谱上的载波且所述待定载波在所述第一控 制信息的资源上处于开启状态"和 "所述待定载波在所述第一控制信息的资 源上处于非连续接收(Discontinuous Reception, DRX ) 的非激活期", 由于 Cell-1是非共享频谱上的载波, 满足第一个条件, 在 Cell-1处于 DRX非激 活期的阶段, 也满足第二个条件。 第三个条件是 "在所述待定载波上发送所 述第一控制信息的资源属于所述待定载波上预配置的用于发送控制信息的 资源"。由于在子帧 n中发送第一数据的第一控制信息的资源为子帧 n的第 1 个 OFDM符号开始的资源。 由于 Cell-1是非共享频谱上的载波, Cell-1上预 配置的资源可以是从该子帧第 1个 OFDM符号开始的 PDCCH资源,或者是 从该子帧第 M(M<4)个 OFDM符号开始的 E-PDCCH资源。 由于在子帧 n中 发送第一数据的第一控制信息的资源为子帧 n+1的第 1个 OFDM符号开始 的资源, 因此, 在 Cell-1 上预配置的用于发送控制信息的资源能够作为在 Cell-1上发送所述第一控制信息的资源。 即 Cell-1满足第三个条件, 可以作 为第一载波。 因此基站确定在子帧 n上 Cell-1为第一载波。
在子帧 n+l, 由于 Cell-3的载波为共享频谱上的载波,基站根据 LBT规 则确定在子帧 n+1能够占用共享频语发送信号。此时在子帧 n+1中发送第一 数据的第一控制信息的资源为子帧 n+1的第 1个 OFDM符号开始或者第 1 个 OFDM符号以后的资源。 这里以在子帧 n中发送第一数据的第一控制信 息的资源为子帧 n的第 1个 OFDM符号开始的资源为例说明。 该步骤所述 基站根据所述第一指示信息和预设条件确定第一载波, 具体为: 根据第一指 示信息所指示的调度载波集合为 Cell-1、 Cell-2, Cell-3 ,优先级顺序为 Cell-2 > Cell-1 > Cell-3。 基站首先判断优先级最高的 Cell-2是否满足预设条件。 第 一个条件是 "所述待定载波为非共享频谱上的载波, 或者所述待定载波为共 享频谱上的载波且所述待定载波在所述第一控制信息的资源上处于开启状 态", 由于 Cell-2是共享频谱上的载波, 基站根据 LBT规则, Cell-2在子帧 n的第 1个 OFDM符号可以占用共享频谱的资源。 因此, 如果在子帧 n中发 送第一数据的第一控制信息的资源为子帧 n的第 1个 OFDM符号开始的资 源, Cell-2在在子帧 n的第 1个 OFDM符号处于开启状态, 因此 Cell-2满足 第一个条件。 第二个条件是 "所述待定载波在所述第一控制信息的资源上处 于非连续接收( Discontinuous Reception, DRX ) 的非激活期", 在 Cell-2处 于 DRX非激活期的阶段, 也满足第二个条件。 最后, 对于第三个条件 "在 所述待定载波上发送所述第一控制信息的资源属于所述待定载波上预配置 的用于发送控制信息的资源", 由于在子帧 n中发送第一数据的第一控制信 息的资源为子帧 n的第 1个 OFDM符号开始的资源。 由于 Cell-2是共享频 谱上的载波, Cell-2上预配置的用于发送控制信息的资源可以是该子帧结束 前 N2 ( N2≤3)个 OFDM符号的资源, 因此, 在 Cell-2上预配置的用于发送控 制信息的资源可以作为在 Cell-2上发送所述第一控制信息的资源。 即 Cell-2 满足第三个条件, 因此基站确定在子帧 n上 Cell-2为第一载波。
步骤 64, 所述用户设备根据所述第一指示信息和预设条件确定第一载 波。 即, 用户设备根据属于调度载波集合的各个载波、 所述属于调度载波集 合的各个载波的优先级顺序和预设条件确定第一载波。 具体的, 所述用户设 备首先根据所述属于调度载波集合的各个载波和所述属于调度载波集合的 各个载波的优先级顺序按照由高到低的顺序确定待定载波, 然后, 所述用户 设备根据所述待定载波和预设条件确定第一载波。 或者, 所述用户设备首先 根据所述属于调度载波集合的各个载波确定待定载波, 然后, 所述用户设备 根据所述待定载波、预设条件和所述属于调度载波集合的各个载波的优先级 顺序确定第一载波。
其中, 所述第一载波为所述调度载波集合中满足所述预设条件的载波中 优先级最高的载波, 所述第一载波用于传输所述第一控制信息。 可选的, 所 述用户根据所述属于调度载波集合的各个载波、所述属于调度载波集合的各 个载波的优先级顺序和预设条件确定第一载波。 例如, 用户设备按照属于调 度载波集合中各个载波优先级的由高到低的顺序依次判断所述调度载波集 合中的载波是否满足所述预设条件, 例如, 用户设备先判断所述调度载波集 合中优先级最高的载波是否满足所述预设条件, 此时优先级最高的载波为所 述待定载波, 如果满足, 则所述优先级最高的载波为所述第一载波, 如果不 满足, 则判断所述调度载波集合中优先级次高的载波是否满足所述预设条 件, 此时优先级次高的载波为所述待定载波, 如果满足, 则所述优先级次高 的载波为所述第一载波, 如果不满足, 按照优先级由高到低的顺序依次判断 各个载波是否满足所述预设条件。
其中, 所述预设条件包括以下条件中的至少一个。 可选的, 预设条件可 以为上述三个条件中的任意一个, 或者任意两个, 或者预设条件为以下三个 条件都需要被满足。 在所述预设条件中, 所述在所述待定载波上发送所述第 一控制信息的资源指的是第一控制信息在所述待定载波上发送时可以占用 的资源。
条件一: 所述待定载波为非共享频谱上的载波, 或者所述待定载波为共 享频谱上的载波且所述待定载波在所述第一控制信息的资源上处于开启状 态。 所述用户设备根据基站的用于指示所述基站在所述共享频谱上处于开启 状态或者处于关闭状态的指示信息确定所述待定载波处于开启状态或者处 于关闭状态。或者所述用户设备根据对预设的特定信号或预设的特定信道的 检测确定所述待定载波处于开启状态或者关闭状态。
条件二: 所述待定载波在所述第一控制信息的资源上处于非连续接收
( Discontinuous Reception, DRX )的非激活期。 所述用户设备根据所述待定 载波的 DRX的配置参数和基站对所述用户设备的调度情况、 数据传输情况 确定 DRX相关各定时器的定时器状态,确定所述待定载波处于 DRX的非激 活期或者处于 DRX的激活期。
条件三: 在所述待定载波上发送所述第一控制信息的资源属于所述待定 载波上预配置的用于发送控制信息的资源。 所述待定载波上预配置的资源可 以是以下资源中的至少一种:
( 1 )所述预配置的资源为所述待定载波中的下行子帧或下行传输期间 的资源。 所述用户设备根据所述待定载波在发送所述第一控制信息的子帧是 否为下行子帧或者为下行传输期间的资源,确定所述待定载波是否满足所述 预设条件。 如果是, 则确定所述待定载波满足所述预设条件; 如果否, 则确 定所述待定载波不满足所述预设条件。 所述用户设备根据基站发送的第三指 示信息确定所述待定载波在发送所述第一控制信息的子帧是否为下行子帧 或者为下行传输期间的资源, 其中, 所述第三指示信息用于指示所述共享频 谱上在发送所述第一控制信息的子帧为下行子帧或者上行子帧的子帧类型 或者, 所述用户设备根据对预设的特定信号或预设的特定信道的检测确 定所述待定载波在发送所述第一控制信息的子帧是否为下行子帧或者为下 行传输期间的资源。
( 2 )所述预配置的资源为所述待定载波上某一下行子帧上的物理下行 控制信道 ( Physical Downlink Control Channel, PDCCH ) 的资源。 即所述下 行子帧的前 1~N (对于系统带宽 A > 10, N=3;对于系统带宽 A ≤ 10, N=4 ) 个 OFDM符号。所述 PDCCH的资源由所述下行子帧上的 PCFICH信道通知 给用户设备。 所述用户设备根据所述待定载波在发送所述第一控制信息的子 帧上的资源是否为所述 PDCCH中的资源确定所述待定载波是否满足所述预 设条件。 如果是, 则确定所述待定载波满足所述预设条件; 如果否, 则确定 所述待定载波不满足所述预设条件。 例如, 如果在所述待定载波上发送所述 第一控制信息的资源从第 ( N!>1 )个 OFDM符号开始, 则在所述待定载 波上发送所述第一控制信息的资源不属于所述待定载波上预配置的用于发 送控制信息的资源,所述待定载波不满足所述预设条件。如果在所待定述载波 上发送所述第一控制信息的资源从第 1个 OFDM符号开始, 则在所述待定 载波上发送所述第一控制信息的资源属于所述待定载波上预配置的用于发 送控制信息的资源 ,所述待定载波满足所述预设条件。
(3) 所述预配置的资源为所述基站为接收所述第一控制信息的用户设 备配置的在所述待定载波上的增强的物理下行控制信道(Enhanced Physical Downlink Control Channel, E-PDCCH )的资源。 所述 E-PDCCH资源在一个 子帧中时域上的起始位置由 PCFICH或者由所述基站通过高层信令通知给所 述用户设备, 所述 E-PDCCH资源在一个子帧中的频域位置由所述基站通过 高层信令通知给所述用户设备。 所述用户设备根据所述待定载波在发送所述 第一控制信息的子帧上的资源是否为所述 E-PDCCH中的资源确定所述待定 载波是否满足所述预设条件。 如果是, 则确定所述待定载波满足所述预设条 件; 如果否, 则确定所述待定载波不满足所述预设条件。 例如, 如果在所述 待定载波上预配置的 E-PDCCH的资源从第 3个 OFDM符号开始,而所述发 送所述第一控制信息的资源从第 M ( M>3 )个 OFDM符号开始, 则在所述 待定载波上发送所述第一控制信息的资源不属于所述待定载波上预配置的 用于发送控制信息的资源,所述待定载波不满足所述预设条件。如果在所述待 定载波上发送所述第一控制信息的资源从第 3个 OFDM符号开始, 则在所 述待定载波上发送所述第一控制信息的资源属于所述待定载波上预配置的 用于发送控制信息的资源 ,所述待定载波满足所述预设条件。
具体如图 7所示, 对于利用 Cell-2发送或接收第一数据的情况: 在子帧 n, 由于 Cell-2的载波为共享频谱上的载波, 用户设备根据基站 的用于指示所述基站在所述共享频谱上处于开启状态或者处于关闭状态的 指示信息确定所述待定载波处于开启状态或者处于关闭状态。或者所述用户 设备根据对预设的特定信号或预设的特定信道的检测确定所述待定载波处 于开启状态或者关闭状态。通过所述基站的指示或用户设备的检测确定基站 在子帧 n的第 6个 OFDM符号开始能够占用共享频语发送信号。 此时在子 帧 n中发送第一数据的第一控制信息的资源为子帧 n的第 k( k≥5 )个 OFDM 符号以后的资源。该步骤所述用户设备根据所述第一指示信息和预设条件确 定第一载波, 具体为: 根据第一指示信息所指示的调度载波集合为 Cell-1、 Cell-2,优先级顺序为 Cell- 1 > Cell-2。用户设备首先判断优先级最高的 Cell-1 是否满足预设条件。 第一个条件和第二个条件分别是 "所述待定载波为非共 享频谱上的载波,或者所述待定载波为共享频谱上的载波且所述待定载波在 所述第一控制信息的资源上处于开启状态," 和 "所述待定载波在所述第一 控制信息的资源上处于非连续接收(Discontinuous Reception, DRX )的非激 活期", 由于 Cell-1是非共享频谱上的载波, 满足第一个条件, 在 Cell-1处 于 DRX非激活期的阶段, 也满足第二个条件。 第三个条件是 "在所述待定 载波上发送所述第一控制信息的资源属于所述待定载波上预配置的用于发 送控制信息的资源"。 由于 Cell-1是非共享频谱上的载波, Cell-1上预配置的 资源可以是从该子帧第 1个 OFDM符号开始的 PDCCH资源,或者是从该子 帧第 M(M<4)个 OFDM符号开始的 E-PDCCH资源。 在 Cell-1上发送所述第 一控制信息的资源不属于在 Cell-1上预配置的用于发送控制信息的资源。 即 Cell-1不满足第三个条件, 不能作为第一载波。 然后根据第一指示信息所指 示的调度载波集合为 Cell-1、 Cell-2, 优先级顺序为 Cell-1 > Cell-2。 用户设 备再判断优先级次高的 Cell-2是否满足预设条件。 Cell-2满足第一个条件"所 述待定载波为非共享频谱上的载波, 或者所述待定载波为共享频谱上的载波 且所述待定载波在所述第一控制信息的资源上处于开启状态", 这是由于 Cell-2能够从子帧 n的第 k ( k≥5 )个 OFDM符号开始占用共享信道发送数 据, 即从第 k个 OFDM符号开始 Cell-2处于开启状态。 第二个条件是 "所 述待定载波在所述第一控制信息的资源上处于非连续接收( Discontinuous Reception, DRX )的非激活期"。 在 Cell-2处于 DRX非激活期的阶段满足第 二个条件。 第三个条件 "在所述待定载波上发送所述第一控制信息的资源属 于所述待定载波上预配置的用于发送控制信息的资源"。 由于 Cell-2是共享 频谱上的载波, Cell-2上预配置的用于发送控制信息的资源可以是该子帧结 束前 N2 ( N2≤3)个 OFDM符号的资源, 因此在 Cell-2上预配置的用于发送控 制信息的资源能够作为在 Cell-2上发送所述第一控制信息的资源。 即 Cell-2 也满足第三个条件, 因此用户设备确定在子帧 n上 Cell-2为第一载波。
在子帧 n+1,由于 Cell-2的载波为共享频语上的载波,用户设备在 Cell-2 的子帧边界开始根据基站的用于指示所述基站在所述共享频谱上处于开启 状态或者处于关闭状态的指示信息确定所述待定载波处于开启状态或者处 于关闭状态。或者所述用户设备根据对预设的特定信号或预设的特定信道的 检测确定所述待定载波处于开启状态或者关闭状态。通过所述基站的指示或 用户设备的检测确定确定基站在子帧 n+1 的开始时刻能够占用共享频语发 送信号。 此时在子帧 n+1中发送第一数据的第一控制信息的资源为子帧 n+1 的第 1个 OFDM符号开始或者第 1个 OFDM符号以后的资源。 该步骤所述 用户设备根据所述第一指示信息和预设条件确定第一载波, 具体为: 根据第 一指示信息所指示的调度载波集合为 Cell-1、 Cell-2, 优先级顺序为 Cell-1 > Cell-20 用户设备首先判断优先级最高的 Cell-1是否满足预设条件。 第一个 条件和第二个条件分别是 "所述待定载波为非共享频谱上的载波, 或者所述 待定载波为共享频谱上的载波且所述待定载波在所述第一控制信息的资源 上处于开启状态" 和 "所述待定载波在所述第一控制信息的资源上处于非连 续接收( Discontinuous Reception, DRX ) 的非激活期", 由于 Cell-1是非共 享频谱上的载波, 满足第一个条件, 在 Cell-1处于 DRX非激活期的阶段, 也满足第二个条件。 第三个条件是 "在所述待定载波上发送所述第一控制信 息的资源属于所述待定载波上预配置的用于发送控制信息的资源"。 由于 Cell-1 是非共享频谱上的载波, Cell-1 上预配置的资源可以是从该子帧第 1 个 OFDM符号开始的 PDCCH资源,或者是从该子帧第 M(M<4)个 OFDM符 号开始的 E-PDCCH资源。 由于在子帧 n中发送第一数据的第一控制信息的 资源为子帧 n+1的第 1个 OFDM符号以后的资源, 因此在 Cell-1上预配置 的用于发送控制信息的资源能够作为在 Cell-1上发送所述第一控制信息的资 源。 即 Cell-1满足第三个条件, 可以作为第一载波。 因此用户设备确定在子 帧 n+1上 Cell-2为第一载波。 对于利用 Cell-3发送或接收第一数据的情况, 如图 7 所示:
在子帧 n, 由于 Cell-3的载波为共享频谱上的载波, 用户设备根据基站 的用于指示所述基站在所述共享频谱上处于开启状态或者处于关闭状态的 指示信息确定所述待定载波处于开启状态或者处于关闭状态。或者所述用户 设备根据对预设的特定信号或预设的特定信道的检测确定所述待定载波处 于开启状态或者关闭状态。通过所述基站的指示或用户设备的检测确定基站 在子帧 n的第 1个 OFDM符号开始能够占用共享频语发送信号。 此时在子 帧 n中发送第一数据的第一控制信息的资源为子帧 n的第 1个 OFDM符号 开始或者第 1个 OFDM符号以后的资源。 这里以在子帧 n中发送第一数据 的第一控制信息的资源为子帧 n的第 1个 OFDM符号开始的资源为例说明。 该步骤所述用户设备根据所述第一指示信息和预设条件确定第一载波, 具体 为: 根据第一指示信息所指示的调度载波集合为 Cell-1、 Cell-2, Cell-3 , 优 先级顺序为 Cell-2 > Cell-1 > Cell-3。 用户设备首先判断优先级最高的 Cell-2 是否满足预设条件。 第一个条件是 "所述待定载波为非共享频谱上的载波, 或者所述待定载波为共享频谱上的载波且所述待定载波在所述第一控制信 息的资源上处于开启状态", 由于 Cell-2是共享频谱上的载波, 用户设备根 据基站的用于指示所述基站在所述共享频谱上处于开启状态或者处于关闭 状态的指示信息确定所述待定载波处于开启状态或者处于关闭状态。或者所 述用户设备根据对预设的特定信号或预设的特定信道的检测确定所述待定 载波处于开启状态或者关闭状态。通过所述基站的指示或用户设备的检测确 定 Cell-2在子帧 n的第 1个 OFDM符号处于关闭状态, 因此 Cell-2不满足 第一个条件, 不能作为第一载波。 然后根据第一指示信息所指示的调度载波 集合为 Cell-1、 Cell-2、 Cell-3 , 优先级顺序为 Cell-2 > Cell-1 > Cell-3 , 用户 设备再判断优先级次高的 Cell-1是否满足预设条件。 第一个条件和第二个条 件分别是 "所述待定载波为非共享频谱上的载波, 或者所述待定载波为共享 频谱上的载波且所述待定载波在所述第一控制信息的资源上处于开启状态" 和 "所述待定载波在所述第一控制信息的资源上处于非连续接收 ( Discontinuous Reception, DRX ) 的非激活期", 由于 Cell-1是非共享频语 上的载波, 满足第一个条件, 在 Cell-1处于 DRX非激活期的阶段, 也满足 第二个条件。 第三个条件是 "在所述待定载波上发送所述第一控制信息的资 源属于所述待定载波上预配置的用于发送控制信息的资源"。 由于在子帧 n 中发送第一数据的第一控制信息的资源为子帧 n的第 1个 OFDM符号开始 的资源。 由于 Cell-1是非共享频谱上的载波, Cell-1上预配置的资源可以是 从该子帧第 1个 OFDM符号开始的 PDCCH资源,或者是从该子帧第 M(M<4) 个 OFDM符号开始的 E-PDCCH资源。由于在子帧 n中发送第一数据的第一 控制信息的资源为子帧 n+1的第 1个 OFDM符号开始的资源,因此在 Cell-1 上预配置的用于发送控制信息的资源能够作为在 Cell-1上发送所述第一控制 信息的资源。 即 Cell-1满足第三个条件, 可以作为第一载波。 因此用户设备 确定在子帧 n上 Cell-1为第一载波。步骤 65,所述基站在所述第一载波发送 所述第一控制信息; 而用户设备在所述第一载波接收所述第一控制信息。
