Description
传输控制方法、 传输方法及设备
技术领域 本发明实施例涉及通信技术, 尤其涉及一种传输控制方法、 传输方法及 设备。 背景技术
在长期演进(Long Time Evolution, 简称为 LTE ) 系统中, 可以在宏小 区下配置覆盖范围较小的新载波类型 (New Carrier Types, 简称为 NCT ) 小 区, 用以提高热点区域的通信容量。 NCT小区是一种使用新型载波配置方案 的小区, 釆用了一种增强型物理下行信道 ( enhance Physical Downlink Control Channel, 简称为 ePDCCH ) , 能够减小导频的数目, 节省频域资源。
在 NCT小区中, 可以根据本小区内用户设备 ( User Equipment, 简称为 UE )获得服务的需求或者根据 NCT小区内基站 ( eNB )本身的省电需求, 将 NCT小区内的 eNB配置为非连续发射 ( Discontinuous Transmission, 简称为 DTX ) , 即 eNB可以交替处于激活态和睡眠态, 这样可以减小 eNB的电量 消耗。 其中, eNB可以配置为周期性 DTX或非周期性 DTX。 相应的, 可以 将 NCT小区内的 UE配置为非连续接收(Discontinuous Reception, 简称为 DRX ) , 以与 eNB的 DTX相适应 , 即在 eNB处于睡眠态不进行数据发送时, UE也不激活进行数据接收。
对于 NCT小区中的 UE, 虽然可以配置为与 eNB的 DTX相适应的 DRX 来节省电量, 但是, 如果 UE在 eNB处于睡眠态期间有上行传输需求, 则会 转换为激活态进行上行传输, 并对相应的下行信道即物理下行控制信道 ( Physical Downlink Control Channel , 简称为 PDCCH )进行监听, 以期待接 收 eNB针对该上行资源授权信息, 同时 UE也可能在此期间对寻呼信道进行 监听。 但在该过程中 , 由于 eNB处于睡眠态, 所以 UE不会接收到 eNB发送 的上行资源授权信息, 这会造成 UE电量的浪费。 发明内容

图 8为本发明实施例提供的又一种 UE的结构示意图。 具体实施方式 为使本发明实施例的目的、 技术方案和优点更加清楚, 下面将结合本发 明实施例中的附图, 对本发明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发明一部分实施例, 而不是全部的实施例。 基于 本发明中的实施例, 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, 都属于本发明保护的范围。
图 1为本发明实施例提供的一种传输控制方法的流程图。 如图 1所示, 本实施例的方法包括:
步骤 101、 网络侧设备生成 DTX睡眠指示信息, 所述 DTX睡眠指示信 息用于标识网络侧设备在执行 DTX 过程中每次进入睡眠态的开始时间和处 于睡眠态的时间长度。
步骤 102、 网络侧设备向网络侧设备下的小区内的 UE发送所述 DTX睡 眠指示信息, 以使 UE根据所述 DTX睡眠指示信息在网络侧设备处于睡眠态 期间, 将 UE的数据处理和 /或传输挂起。
在本实施例中, 网络侧设备可以是 eNB, 但不限于此。
网络侧设备的传输模式被配置为 DTX模式, 可以是周期性 DTX, 也可 以是非周期的 DTX。 在 DTX模式下, 网络侧设备在执行 DTX过程中会交替 处于激活态和睡眠态, 这样可以减小网络侧设备的电量消耗。
网络侧设备生成标识网络侧设备在执行 DTX 过程中每次进入睡眠态的 开始时间和处于睡眠态的时间长度的 DTX睡眠指示信息,并将所生成的 DTX 睡眠指示信息发送给 UE, 这样 UE根据网络侧设备发送的 DTX睡眠指示信 息, 可以获知网络侧设备在什么时候进入睡眠态并且可以获知网络侧设备处 于睡眠态的时间长度,之后, UE可以在网络侧设备每次处于睡眠态期间将自 己的数据处理和 /或传输挂起, 直至网络侧设备重新转换为激活态的时候, UE
恢复数据处理和 /或传输, 从而节约在网络侧设备处于睡眠态期间进行数据处 理和 /或传输消耗的电量, 有利于进一步节约 UE的电量。
本发明实施例所述的 "将数据处理和 /或传输挂起" 主要是指暂停进行数 据处理和 /或传输。
在本实施例中, UE在网络侧设备处于睡眠态期间挂起的数据处理和 /或 传输可以包括分组数据汇聚协议 ( Packet Data Convergence Protocol, 简称为 PDCP )层、 无线链路控制 (Radio Link Control, 简称为 RLC )层以及介质访 问控制 (Media Access Control, 简称为 MAC )层等各层的数据处理和 /或传 输。 下面举例说明:
UE根据网络侧设备发送的 DTX睡眠指示信息, 在网络侧设备处于睡眠 态期间, 将 UE的数据处理和 /传输挂起包括以下任一操作或其组合:
UE根据所述 DTX睡眠指示信息, 在网络侧设备处于睡眠态期间, 停止 各层协议数据单元( Protocol Data Unit, 简称为 PDU ) 的装配。
UE根据所述 DTX睡眠指示信息, 在网络侧设备处于睡眠态期间, 禁止 调度请求( Scheduling Request, 简称为 SR ) 的发送。
UE根据所述 DTX睡眠指示信息, 在网络侧设备处于睡眠态期间, 配置 待发送上行数据不属于任何逻辑信道, 即不会触发 UE向网络侧发送緩存状 态报告(Buffer State Report, 简称为 BSR ) , 从而不会进行上行数据的发送。
UE根据所述 DTX睡眠指示信息, 在网络侧设备处于睡眠态期间, 禁止 随机接入序列码(preamble ) 的发送, 且不对寻呼信道进行监听。
其中, 对于处于无线资源控制 ( Radio Resource Control , 简称为 RRC ) 连接状态的 UE和处于空闲状态的 UE来说, 其所挂起的数据处理和 /或数据 传输会有所不同。 这点可参见后面的举例说明。
在一可选实施方式中, 网络侧设备配置的 DTX为周期性 DTX, 则网络 侧设备上会存储有周期性 DTX的配置信息, 该配置信息包括 DTX的周期长 度、 开始执行 DTX过程的时间和每个 DTX周期内的睡眠时长。 其中, 一个 DTX 的周期长度由一个激活态的时长和一个睡眠态的时长构成。 根据 DTX 的周期长度和每个 DTX周期内的睡眠时长, 可以确定出每个 DTX周期内的 激活态的时长, 再结合开始执行 DTX过程的时间, 就可以确定出网络侧设备 在每个 DTX周期内进入睡眠态的时间, 而每个 DTX周期内的睡眠时长即为
网络侧设备每次处于睡眠态的时间长度。 在该情况下, 网络侧设备可以在执 行 DTX过程之前,根据周期性 DTX的配置信息,生成所述 DTX睡眠指示信 息。 在该实施方式中, DTX睡眠指示信息包括但不限于: DTX的周期长度、 开始执行 DTX过程的时间和每个 DTX周期内的睡眠时长等。
基于上述, 网络侧设备向其下的小区内的 UE发送所述 DTX睡眠指示信 息, 以使 UE根据所述 DTX睡眠指示信息在网络侧设备处于睡眠态期间, 将 UE的数据处理和 /或传输挂起的过程包括: 网络侧设备可以从执行 DTX过程 开始,周期性的向网络侧设备下的小区内的 UE广播所述 DTX睡眠指示信息, 以使 UE根据所述 DTX睡眠指示信息在网络侧设备处于睡眠态期间, 将 UE 的数据处理和 /或传输挂起。 其中, 网络侧设备可以以广播或单播等方式, 向 UE发送所述 DTX睡眠指示信息。
其中, 网络侧设备在执行 DTX过程中, 周期性的广播所述 DTX睡眠指 示信息, 有利于在各个时间加入网络的 UE及时获得网络侧设备每次进入睡 眠态的开始时间和处于睡眠态的时间长度, 因此, 是一种优选实施方式。
在一可选实施方式中, 网络侧设备配置的 DTX为非周期 DTX。 在这种 情况下, 网络侧设备在执行 DTX过程中, 会根据实际应用情况无规律的进入 睡眠态, 且网络侧设备每次处于睡眠态的时间长度也没有固定的规律。 基于 此,本实施例提供一种网络侧设备生成非连续发射 DTX睡眠指示信息的实施 方式, 包括: 网络侧设备在执行 DTX过程中每次进入睡眠态之前, 生成所述 DTX睡眠指示信息, 所述 DTX睡眠指示信息包括: 本次进入睡眠态的开始 时间和本次处于睡眠态的时长。 其中, 网络侧设备根据实际应用情况, 在进 入睡眠态之前, 会决定本次进入睡眠态的时间以及处于睡眠态的时长, 故在 每次进入睡眠态之前 , 生成包括本次进入睡眠态的开始时间和本次处于睡眠 态的时长的 DTX睡眠指示信息。
基于上述, 网络侧设备向网络侧设备下的小区内的 UE发送所述 DTX睡 眠指示信息, 以使 UE根据所述 DTX睡眠指示信息在网络侧设备处于睡眠态 期间, 将 UE的数据处理和 /或传输挂起的另一种实施方式包括: 网络侧设备 在执行 DTX过程中每次进入睡眠态之前 , 向网络侧设备下的小区内的 UE发 送所述 DTX睡眠指示信息, 以使 UE根据所述 DTX睡眠指示信息在网络侧 设备处于睡眠态期间, 将 UE的数据处理和 /或传输挂起。
例如, 网络侧设备可以在执行 DTX过程中每次进入睡眠态之前, 通过寻 呼消息或者 MAC层控制单元(Control Element, 简称为 CE )或者下行控制 信息( Downlink Control Information, 简称为 DCI ) , 向网络侧设备下的小区 内的 UE发送所述 DTX睡眠指示信息, 以使 UE根据所述 DTX睡眠指示信 息在网络侧设备处于睡眠态期间, 将 UE的数据处理和 /或传输挂起。
可选的, 为了增加可靠性, 保证 UE的正确接收, 网络侧设备可以在执 行 DTX过程中每次进入睡眠态之前 , 多次向网络侧设备下的小区内的 UE发 送所述 DTX睡眠指示信息, 以保证 UE能够正确接收并解码此 DTX睡眠指 示信息,从而使 UE根据所述 DTX睡眠指示信息在网络侧设备处于睡眠态期 间, 将 UE的数据处理和 /或传输挂起。
下面结合网络侧设备配置的是周期性 DTX还是非周期 DTX, 以及 UE 是处于 RRC连接态还是处于 RRC空闲态, 对本发明技术方案的具体实施方 式及其效果进行举例说明。
现有技术中,对于 NCT小区中处于 RRC连接态的 UE, 虽然可以配置为 与网络侧设备的 DTX相适应的 DRX来节省电量, 但是, 如果 UE在网络侧 设备处于睡眠态期间有上行数据需要发送, 则会向网络侧设备发送 SR请求 上行资源, 并转换为激活态对物理下行控制信道 ( Physical Downlink Control Channel, 简称为 PDCCH )进行监听, 以期望接收上行资源授权消息, 但在 该过程中, 由于网络侧设备处于睡眠态, 所以 UE不会接收到上行资源授权 消息, UE会多次重发 SR, 造成电量的浪费。
另外, 现有技术中, 对于 NCT小区下处于 RRC空闲态的 UE, 如果需要 在网络侧设备在处于睡眠态期间与网络侧设备建立 RRC连接,以进行数据传 输, 则会触发随机接入过程, 但在该期间 UE 不可能收到随机接入响应 ( Random Access Response, 简称为 RAR ) , 会导致 UE重传随机接入序列码 ( preamble ) , 造成了 UE电量的浪费和额外的信令开销。
在 NCT小区的网络侧设备配置为周期性 DTX的场景下,为解决处于 RRC 连接态的 UE多次重复发送 SR造成电量浪费, 以及处于 RRC空闲态的 UE 重传序列码造成电量浪费以及增加额外信令开销等问题, 本实施例的方法包 括: 网络侧设备根据其执行 DTX过程的配置信息, 生成所述 DTX睡眠指示 信息, 然后在小区内广播所述 DTX睡眠指示信息, 该 DTX睡眠指示信息包
括但不限于: DTX的周期长度、 开始执行 DTX的时间点以及每个 DTX周期 内的睡眠时长等。 在该场景下, 网络侧设备每次处于睡眠态的时间长度相同。
对于 NCT小区中处于 RRC连接态的 UE,可以接收并解码网络侧设备广 播的所述 DTX指示信息, 在成功解码所述 DTX睡眠指示信息后, 即可获得 网络侧设备在整个 DTX 过程每次进入睡眠态的起始时间以及每次处于睡眠 态的时间长度等具体信息。这样每当网络侧设备从激活态转入睡眠态, UE在 此期间将自己的 PDCP/RLC/MAC层等的数据处理和 /或传输挂起, 直到网络 侧设备重新转换为激活态, 当 UE重新转换为激活态时, UE从执行 "挂起" 时的状态继续相应的数据处理和 /或传输。 这里的 "挂起" 包括但不限于停止 各层 PDU的装配、 禁止 SR发送、 配置待发数据不属于任何逻辑信道等。 处 于 RRC连接态的 UE通过将自己各层的数据处理和 /或传输挂起,可以节约在 网络侧设备处于睡眠态期间进行数据处理和 /或传输消耗的电量。
对于 NCT小区中处于 RRC空闲态的 UE,可以接收并解码网络侧设备广 播的所述 DTX指示信息, 在成功解码所述 DTX睡眠指示信息后, 即可获得 网络侧设备在整个 DTX 过程每次进入睡眠态的起始时间以及每次处于睡眠 态的时间长度等具体信息。这样每当网络侧设备从激活态转入睡眠态, UE将 自己的数据处理和 /或传输挂起主要是指 UE禁止随机接入序列码的发送, 即 UE禁止执行随机接入过程。 可选的, 在 UE收到网络侧设备执行 DTX过程 的相关信息后, 可以进行判断, 如果能接受网络侧设备每次处于睡眠态的时 长, 则继续驻留在本小区; 否则, UE通过执行小区重选驻留到其它小区。 处 于 RRC空闲态的 UE通过禁止序列码的发送, 可以节约在网络侧设备处于睡 眠态期间发起随机接入过程消耗的电量以及节约在此期间发起随机接入过程 所消耗的信令开销。
在 NCT小区的网络侧设备配置为非周期 DTX的场景下,为解决处于 RRC 连接态的 UE多次重复发送 SR造成电量浪费, 以及处于 RRC空闲态的 UE 重传序列码造成电量浪费以及增加额外信令开销等问题, 本实施例的方法包 括: 网络侧设备在执行 DTX过程中, 每次进入睡眠态之前, 生成携带有网络 侧设备本次进入睡眠态的开始时间和本次处于睡眠态的时长的 DTX 睡眠指 示信息; 然后, 向 UE发送所述 DTX睡眠指示信息。 例如, 网络侧设备可以 通过寻呼消息或 MAC CE或 DCI携带所述 DTX睡眠指示信息, 发送给 UE。
在该场景下, 网络侧设备每次处于睡眠态的时间长度可能不同。 可选的, 为 了增加可靠性,保证 UE正确接收,网络侧设备可以多次向 UE发送所述 DTX 睡眠指示信息。
对于 NCT小区中处于 RRC连接态的 UE,可以接收并解码网络侧设备发 送的所述 DTX指示信息, 在成功解码所述 DTX睡眠指示信息后, 即可获得 网络侧设备在整个 DTX 过程每次进入睡眠态的起始时间以及每次处于睡眠 态的时间长度等具体信息。这样每当网络侧设备从激活态转入睡眠态, UE在 此期间将自己的 PDCP/RLC/MAC层等的数据处理和 /或传输挂起, 直到网络 侧设备重新转换为激活态, 当 UE重新转换为激活态时, UE从执行 "挂起" 时的状态继续相应的数据处理和 /或传输。 这里的 "挂起" 包括但不限于停止 各层 PDU的装配、 禁止 SR发送、 配置待发数据不属于任何逻辑信道等。 处 于 RRC连接态的 UE通过将自己各层的数据处理和 /或传输挂起,可以节约在 网络侧设备处于睡眠态期间进行数据处理和 /或传输消耗的电量。
对于 NCT小区中处于 RRC空闲态的 UE,可以接收并解码网络侧设备发 送的所述 DTX指示信息, 在成功解码所述 DTX睡眠指示信息后, 即可获得 网络侧设备在整个 DTX 过程每次进入睡眠态的起始时间以及每次处于睡眠 态的时间长度等具体信息。这样每当网络侧设备从激活态转入睡眠态, UE将 自己的数据处理和 /或传输挂起主要是指 UE禁止序列码的发送, 即 UE禁止 执行随机接入过程。 可选的, 在 UE收到网络侧设备执行 DTX过程的相关信 息后, 可以进行判断, 如果能接受网络侧设备每次处于睡眠态的时长, 则继 续驻留在本小区; 否则, UE通过执行小区重选驻留到其它小区。 处于 RRC 空闲态的 UE通过禁止序列码的发送, 可以节约在网络侧设备处于睡眠态期 间发起随机接入过程消耗的电量以及节约在此期间发起随机接入过程所消耗 的信令开销。
在此说明 ,对于处于 RRC连接态的 UE, 可以接收通过寻呼消息或 MAC
CE或 DCI携带的所述 DTX睡眠指示信息; 而对于处于 RRC空闲态的 UE, 只能接收通过寻呼消息携带的所述 DTX睡眠指示信息。
基于上述各实施方式, 在一可选实施方式中, 如果网络侧设备本次处于 睡眠态的时间长度大于预设的睡眠时长阈值, 则网络侧设备在处于睡眠态期 间, 接收 UE发送的指示信息, 所述指示信息是 UE在根据所述 DTX睡眠指
示信息确定网络侧设备本次处于睡眠态的时间长度大于预设的睡眠时长阈值 后, 在网络侧设备本次处于睡眠态期间在预设的时间点或周期性发送的。 然 后, 网络侧设备根据所述指示信息的平均信号强度和 /或所述指示信息的出现 密度, 确定是否提前进入 DTX过程中的激活态。
在该实施方式中, 预先设定睡眠时长阈值, 用于判断网络侧设备每次处 于睡眠态的时间是否过长; 如果网络侧设备某次处于睡眠态的时长大于该预 先设定的睡眠时长阈值, 则说明网络侧设备处于睡眠态的时间过长, 于是网 络侧可以考虑是否提前进入 DTX过程中激活态, 以便于能够及时为 UE提供 服务。 在该实施方式中, 预设的睡眠时长阈值同时配置在网络侧设备和 UE 上, UE接收到网络侧设备发送的所述 DTX睡眠指示信息后, 可以根据预设 的睡眠时长阈值判断出网络侧设备本次处于睡眠态的时间过长, 如果是, 则 即使网络侧设备处于睡眠态也向网络侧设备发送指示信息, 具体的可以在网 络侧设备本次处于睡眠态期间指定的时间点或周期性的发送指示信息。另夕卜, 小区内的各个 UE在判断出网络侧设备本次处于睡眠态的时间过长后, 都可 以向网络侧设备发送指示信息。 基于此, 网络侧设备在本次处于睡眠态期间 可能会接收到多个指示信息, 于是对多个指示信息的信号强度进行平均, 获 得指示信息的平均信号强度, 或者对多个指示信息出现的时间进行统计, 获 得指示信息的出现密度(这个出现密度是从指示信息的出现频率上进行考虑 的) , 或者对发送指示信息的 UE进行统计, 获得指示信息的出现密度(这 个出现密度是从发送指示信息的 UE的多少来考虑的) , 然后根据指示信息 的平均信号强度和 /或指示信息的出现密度, 确定是否提前进入 DTX过程中 的激活态, 即确定是否提前退出睡眠态。
例如, 网络侧设备可以预先存储一个信号强度阈值和 /或出现密度阈值, 通过将获得的指示信息的平均信号强度和 /或出现密度, 分别与预先存储的信 号强度阈值和 /或出现密度阈值进行比较,如果大于该信号强度阈值和 /或出现 密度阈值, 则可以提前进入 DTX过程中的激活态; 反之, 保持当前所处的睡 眠态。
其中, UE发送的指示信息可以包括但不限于: 上行导频、 SR、 探测参 考信号 ( Sounding Reference Signal, 简称为 SRS )等。
进一步可选的, 网络侧设备在处于睡眠态期间, 接收所述 UE发送的指
示信息之前包括: 如果网络侧设备本次处于睡眠态的时间长度大于所述睡眠 时长阈值, 网络侧设备在处于睡眠态期间, 至少一次进入短激活态, 并在所 述短激活态向 UE发送下行导频信号,以使 UE根据所述下行导频信号的强度 发送所述指示信息。 所述短激活态是指网络侧设备在睡眠态期间在短时间内 进入的激活态, 该短激活态的时间要远小于 DTX过程中正常的激活态时间, 且在短激活态期间, 网络侧设备仅能发送下行导频信号。 所述下行导频信号 包括但不限于: 小区专用参考信号 (Cell-specific Reference Signal, 简称为 CRS )、 主同步信号( Primary Synchronization Signal, 简称为 PSS )、 辅同步 信号 (Secondary Synchronization Signal, 简称为 SSS ) 。 网络侧设备可以在 本次处于睡眠态期间内指定的时间点或周期性的进入短激活态。 其中, 网络 侧设备发送下行导频信号并不会消耗太多电量。 在该实施方式中, 网络侧设 备在睡眠态期间通过进入短激活态, 并在短激活态向 UE发送下行导频信号, 引导 UE根据检测到的导频信号强度来决定是否在该网络侧设备处于短激活 态期间发送指示信息, 以指示需要网络侧设备为其提供服务, 同时使网络侧 设备根据接收到的指示信息确定是否提前进入 DTX过程中激活态。
基于上述 UE在网络侧设备处于睡眠态期间向网络侧设备发送指示信息 的实施方式, 本实施例提供的传输控制方法还包括:
网络侧设备在执行 DTX过程中每次进入睡眠态之前,判断即将处于睡眠 态的时间长度是否大于所述睡眠时长阈值。 如果判断结果为是, 则网络侧设 备在进入所述时间长度大于所述睡眠时长阈值的睡眠态之前, 向 UE发送所 述网络侧设备的时钟信息, 以使所述 UE根据所述时钟信息在所述网络侧设 备处于所述时间长度大于所述睡眠时长阈值的睡眠态期间, 对所述网络侧设 备进行周期性的监听以判断所述网络侧设备是否提前进入 DTX过程中的激 活态。
由于网络侧设备可能会提前进入 DTX过程中的激活态, 而 UE无法知道 网络侧设备具体在何时进入 DTX过程中的激活态, 因此, 需要对网络侧设备 进行监听以判断网络侧设备是否提前进入 DTX过程中的激活态。 又因为, 如 果 UE—直对网络侧设备进行监听,将会浪费 UE的电量,所以优先的实施方 式是: UE 在网络侧设备处于睡眠态的时长大于预设的睡眠时长阈值的情况 下,周期性的监听网络侧设备以便判断网络侧设备是否提前进入 DTX过程中
的激活态。 但是, 在网络侧设备处于睡眠态期间, UE 的数据处理和 /或传输 已经被挂起, 所以 UE本地的时钟信息就会丟失, 故需要网络侧设备提供一 个时钟信息, 以便于 UE 实现周期性的监听网络侧设备。 基于此, 网络侧设 备在进入睡眠态之前, 首先确定本次处于睡眠态的时间是否过长, 如果本次 处于睡眠态的时间过长, 则将自己的时钟信息发送给小区内的 UE, 以便于 UE根据该时钟信息对网络侧设备进行周期性的监听,进而判断网络侧设备是 否提前进入 DTX过程中的激活态。 这样当 UE判断出网络侧设备提前进入 DTX过程中的激活态, 则可以及时向网络侧设备上传数据。
在此说明, 上述各个涉及 UE在网络侧设备处于睡眠态的时长大于预设 的睡眠时长阈值时, 在网络侧设备处于睡眠态期间, 向网络侧设备上 ·艮指示 信息的各个实施方式, 尤其适用于网络侧设备被配置为非周期 DTX的场景, 因为在该场景下, 网络侧设备每次处于睡眠态的时长是不同的, 但并不限于 这种场景。
图 2为本发明实施例提供的一种传输方法的流程图。 如图 2所示, 本实 施例的方法包括:
步骤 201、 UE接收网络侧设备发送的 DTX睡眠指示信息, 所述 DTX睡 眠指示信息用于标识网络侧设备在执行 DTX 过程中每次进入睡眠态的开始 时间和处于睡眠态的时间长度。
步骤 202、 UE根据所述 DTX睡眠指示信息, 在网络侧设备处于睡眠态 期间, 将所述 UE的数据处理和 /或传输挂起。
在一可选实施方式中, 步骤 201的一种实施方式包括: UE接收网络侧设 备从执行 DTX过程开始周期性广播的所述 DTX睡眠指示信息。 该实施方式 适用于网络侧设备配置为周期性 DTX的场景。
在一可选实施方式中, 步骤 201的另一种实施方式包括: UE接收网络侧 设备在执行 DTX过程中每次进入睡眠态之前发送的所述 DTX睡眠指示信息。 该实施方式尤其适用于网络侧设备配置为非周期 DTX的场景, 但不限于此。 进一步可选的, UE可以接收网络侧设备在执行 DTX过程中每次进入睡眠态 之前发送的寻呼消息或 MAC层 CE或 DCI, 所述寻呼消息或 MAC层 CE或 DCI携带有所述 DTX睡眠指示信息。 在此说明, 如果 UE处于 RRC连接态, 则 UE可以接收通过寻呼消息或 MAC层 CE或 DCI携带的所述 DTX睡眠指
示信息; 如果 UE处于 RRC空闲态, 则 UE只能接收通过寻呼消息携带的所 述 DTX睡眠指示信息。
本实施例中, UE根据所述 DTX睡眠指示信息, 在网络侧设备处于睡眠 态期间, 所挂起的数据处理和 /或传输包括 PDCP层、 RLC层以及 MAC层等 各层的数据处理和 /或传输。 举例说明, UE根据所述 DTX睡眠指示信息, 在 网络侧设备处于睡眠态期间, 将 UE的数据处理和 /或传输挂起包括以下任一 操作或其组合:
UE根据所述 DTX睡眠指示信息, 在网络侧设备处于睡眠态期间, 停止 各层协议数据单元( Protocol Data Unit, 简称为 PDU ) 的装配。
UE根据所述 DTX睡眠指示信息, 在网络侧设备处于睡眠态期间, 禁止
SR的发送。
UE根据所述 DTX睡眠指示信息, 在网络侧设备处于睡眠态期间, 配置 待发送上行数据不属于任何逻辑信道, 即不会触发 UE向网络侧发送 BSR, 从而不会进行上行数据的发送。
UE根据所述 DTX睡眠指示信息, 在网络侧设备处于睡眠态期间, 禁止 随机接入序列码(preamble ) 的发送, 且不对寻呼信道进行监听。
在一可选实施方式中, UE在接收到网络侧设备发送的 DTX睡眠指示信 息后, 可以根据所述 DTX睡眠指示信息, 判断网络侧设备本次处于睡眠态的 时间长度是否大于预设的睡眠时长阈值; 如果判断结果为是, UE在网络侧设 备处于睡眠态期间,在预设的时间点或周期性的向网络侧设备发送指示信息, 以使网络侧设备根据所述指示信息的平均信号强度和 /或所述指示信息的出 现密度, 确定是否提前进入 DTX过程中的激活态。
进一步可选的, UE在网络侧设备处于睡眠态期间,在预设的时间点或周 期性向网络侧设备发送指示信息之前包括: UE接收网络侧设备在处于睡眠态 期间发送的下行导频信号, 所述下行导频信号是网络侧设备在本次处于睡眠 态的时间长度大于所述睡眠时长阈值时, 在本次睡眠态期间至少一次进入的 短激活态向 UE发送的。 基于此, UE在网络侧设备处于睡眠态期间, 在预设 的时间点或周期性向网络侧设备发送指示信息包括: UE根据所述下行导频信 号的强度, 在预设的时间点或周期性向网络侧设备发送所述指示信息。 例如, 如果下行导频信号的强度大于预设的强度阈值, 则 UE可以在预设的时间点
或周期性向网络侧设备发送所述指示信息。
基于上述 UE在网络侧设备处于睡眠态期间, 向网络侧设备发送指示信 息的实施方式, 考虑到网络侧设备可能会提前进入 DTX 过程中的激活态, UE为了能够及时获知网络侧设备是否提前进入 DTX过程中的激活态, 较为 优选的是周期性的对网络侧设备进行监听。 但是由于在网络侧设备处于睡眠 态期间, UE将数据处理和 /或传输已经挂起, 故 UE的时钟信息会丟失, 故为 了周期性的对网络侧设备进行监听, 需要网络侧设备向 UE提供一个时钟信 息。 基于此, 网络侧设备会在即将处于睡眠态的时间长度大于所述睡眠时长 阈值的情况下, 向 UE发送自己的时钟信息。 而 UE会在网络侧设备本次处于 睡眠态的时间长度大于所述睡眠时长阈值的情况下, 在所述网络侧设备进入 本次睡眠态之前, 接收网络侧设备发送的网络侧设备的时钟信息, 并根据所 述时钟信息在网络侧设备处于本次睡眠态期间对网络侧设备进行周期性的监 听, 以判断网络侧设备是否提前进入 DTX过程中的激活态。
本实施例提供的传输方法是从 UE的角度进行的描述, 其详细操作流程 可参见图 1所示传输控制方法实施例中的描述, 在此不再赘述,
本实施例提供的传输方法, UE根据网络侧设备提供的网络侧设备在执行 DTX过程中每次进入睡眠态的开始时间以及处于睡眠态的时长, 确定网络侧 设备何时进入睡眠态以及处于睡眠态的时长, 进而在网络侧设备处于睡眠态 期间, 将自己的数据处理和 /或传输挂起, 以节约在网络侧设备处于睡眠态期 间进行数据处理和 /或传输所消耗的电量及信令开销等。
