为了更清楚地说明本发明实施例中的技术方案,下面将对实施例中所需要 使用的附图作简单地介绍, 显而易见地, 下面描述中的附图仅仅是本发明的一 些实施例, 对于本领域普通技术人员来讲, 在不付出创造性劳动的前提下, 还 可以根据这些附图获得其他的附图。
图 1 为本发明实施例提供的释放非授权频谱后的数据处理方法的一实施 例流程示意图;
图 2为本发明实施例提供的用户设备的一实施例的结构组成示意
图 3为本发明实施例提供的用户设备的一实施例的结构组成示意
图 4是本发明实施例提供的监测模块的一实施例的结构组成示意
图 5为本发明实施例提供的用户设备的一实施例的结构组成示意图。 具体实肺式
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, 所描述的实施例仅仅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做出创造 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。
具体实现中, 非授权频谱由很多用户共享, 这些用户可能属于不同的无线 接入技术 (RAT, radio access technology) , 如 LTE、 wifi、 蓝牙 (bluetooth) 等。 使用非授权频谱的 LTE、 wifi和蓝牙等设备需要在传输前先侦听频谱是否 空闲, 即 "讲前先听 (LBT, Listen before Talk) " , 以避免对正在使用非授 权频谱的其他用户的干扰。用户获取到非授权频谱后的最大占用时间也有相应 的规定, 需要在使用一定时间后释放, 空闲一定时间然后重新开始竞争非授权 频谱, 从而给予各用户以公平竞争和使用非授权频谱的机会。 比如, 以 LTE系 统和 wifi***在非授权频谱共存为例进行说明。 其中, LTE***为蜂窝***的 代表, 其他的蜂窝***还可以包括 UMTS、 GSM、 CDMA2000等; wifi为异系 统的代表。 具体实现中, LTE基站根据发射功率和下行 (downlink) 覆盖范围 的不同一般可以分为微基站 (Pico eNB ) 、 小基站 (Micro或 small eNB ) 或宏 基站 (macro eNB ) , 本发明后续所涉及的基站可以是上述 LTE***中的各种 基站。 具体实现中, LTE***使用非授权频谱时, 在基站的覆盖区域可能存在 异***如 wifi***使用同一频带的非授权频谱,在 LTE***和 wifi***的共同覆 盖区域可能存在同频干扰, 例如当 LTE***和 wifi***的覆盖有重叠且频率有 重叠时, 如果 LTE***和 wifi***在有重叠的频率范围同时在各自的***进行 通信, 则可能导致同频干扰。 因此, LTE***和 wifi***需要在***间进行协 作或者各***的设备均通过检测和避让等方式共享非授权频谱,以使各***都 能够正常进行通信。 由此, 便可能存在本发明实施例所述的 LTE***或 wifi系 统需要释放非授权频谱,并在空闲一段时间后重新竞争并获取所述非授权频谱 的情形, 以维持 LTE***和 wifi***的非授权频谱的共享。 本发明实施例后续 的部分实施例中,将以 LTE***中的基站释放非授权频谱后的相关数据处理为 例, 对各种***的非授权频谱释放后的处理流程进行举例说明, 由此, 后续的 方法同样适用于 LTE***之外的其他***。
进一步, 在 LTE***中, 3GPP长期演进高级技术 (LTE-A , long term evolution advanced) 载波聚合 (CA, carrier aggregation )通过将多个连续或者 非连续的分量载波 (CC, component carrier) 进行聚合以提高用户峰值数据速 率和***吞吐量。 所聚合的分量载波包括一个主小区 (PCell, Primary) 和 0 至 5个辅小区 (SCdl, secondary cell) , 最大支持 lOOMHz带宽。 PCell和 SCell 可以共站址 (collocate或 co-site) 或者非共站址, 后者例如由基站和远端射频 头(RRH, remote radio head)分别提供 PCell和 SCell。 PCell是用户设备(UE, user equipment ) 执行随机接入过禾呈 (random access procedure ) 初始接入*** 时的小区 (cell) 或者执行切换过程 (handover procedure) 接入到目标基站时 的小区。 PCell还提供安全性(security)和非接入层(NAS, Non-Access Stratum) 信令传输。 SCdl主要提供额外的无线资源用于数据传输。 LTE-A可以通过 CA 技术利用非授权频谱。 因此, 后续的部分实施例中, 将以 SCdl利用非授权频 谱为例进行说明。
具体的, 图 1为本发明的释放非授权频谱后的数据处理方法的一实施例的 流程示意图。 如图 1所示, 其可包括:
步骤 S110, 当用户设备确定基站释放了非授权频谱, 所述用户设备监测 所述基站对所述非授权频谱的释放时间的长短,所述释放时间指示所述基站从 释放非授权频谱至重新获取所述非授权频谱的时间间隔。
步骤 S111 , 当所述释放时间未超过时间阈值, 所述用户设备暂停依附于 所述非授权频谱的数据处理过程, 并在所述基站重新获取所述非授权频谱后, 恢复所述数据处理过程。
步骤 S112, 当所述释放时间超过所述时间阈值, 所述用户设备终止依附 于所述非授权频谱的数据处理过程,并选择授权频谱重新开始新的数据处理过 程或者在所述基站重新获取所述非授权频谱后, 重新开始新的数据处理过程。
具体实现中,在步骤 S110或者在步骤 S110之前,用户设备确定基站释放 了非授权频谱, 其确定方法包括但不限于如下方式:
所述用户设备在接收到所述基站发送的释放非授权频谱的指示信息时确 定所述基站释放了非授权频谱;
或者,
所述用户设备根据所述基站的参数检测到所述基站释放了所述非授权频 谱。
以 LTE-A ***为例, 基站获取到非授权频谱后, 基站和用户设备 (UE) 通过 SCdl 的无线资源进行通信。 通信一段时间之后, 基站释放非授权频谱, 则基站向 UE发送非授权频谱释放指示信息,上述指示信息可通过物理下行控 制信道(包括物理下行控制信道(Physical downlink control channel, PDCCH) 或增强的物理下行控制信道 ( enhanced physical downlink control channel , EPDCCH) )发送,或者,通过媒体接入层控制控制元素(Medium access control control element, MAC CE) 发送。 这样当 UE接收到基站通过 PDCCH 或 EPDCCH或 MAC CE发送的释放非授权频谱的指示信息时, 便可确定所述基 站释放了非授权频谱。 或者, UE通过对 LTE参考信号的测量检测到基站释放 了非授权频谱。
具体实现中, 在步骤 S110, 所述用户设备监测基站对非授权频谱的释放 时间的长短的方式, 包括但不限于如下这些方式:
方式 1 : 所述用户设备启动一个等待时间定时器用于记录所述基站对非授 权频谱的释放时间的长短, 当所述等待时间定时器未超时,确定所述释放时间 未超过所述时间阈值, 当所述等待时间定时器超时后,确定所述释放时间超过 所述时间阈值。
仍以 LTE-A***为例, 当 UE确定基站释放了非授权频谱后, 启动等待 时间定时器 (可记为: wait-timer) , 用于记录所述基站对非授权频谱的释放时 间的长短,若在 UE接收到基站发送的重新获取到非授权频谱的指示之前或者 UE未检测到基站重新获取了非授权频谱, 均说明非授权频谱还处于释放时间 段内, 由此, 本发明实施例, 当在基站重新获取到非授权频谱并指示 UE之前 或者 UE重新检测到基站获取了非授权频谱之前(说明非授权频谱的释放时间 在继续), 若等待时间定时器未超时, 确定所述释放时间未超过时间阈值; 而 当在基站重新获取到非授权频谱并指示 UE之前或者 UE重新检测到基站获取 了非授权频谱之前 (说明非授权频谱的释放时间在继续),若等待定时器超时, 确定所述释放时间超过时间阈值。在该方式中, 等待定时器的超时时间点即为 所述时间阈值。具体实现中, 等待时间定时器可以是单独的定时器, 或者重用 现有技术的去激活定时器 (sCdlDeactivationTimer) , UE接收到基站的释放非 授权频谱指示或者自己检测到非授权频谱释放,可以启动或重新启动去激活定 时器, 或者如果去激活定时器已经运行, 则继续维持去激活定时器; 在去激活 定时器超时前, 确定释放时间未超过时间阈值, 当去激活定时器超时后, 确定 释放时间超过所述时间阈值。
方式 2: 所述用户设备接收基站发送的具体的非授权频谱的释放时间, 并 将所述接收的释放时间与预先设置的时间阈值比较,以确定所述接收的释放时 间是否超过所述预先设置的时间阈值。
具体实现中,所述具体的非授权频谱的释放时间至少包括如下时间中的一 种: 所述非授权频谱被其他设备占用的时间 (比如, 基站检测到高优先级设备 如雷达占用了非授权频谱时,将雷达占用非授权频谱的时间发送给 UE)、所述 非授权频谱的释放和获取的间隔周期(例如周期信息可以是规律性的子帧模式 ( subframe pattern)信息, 表示释放到下一次获取到频谱之间的时间间隔, 该 规律是周期性的。 所述周期由共享非授权频谱的***之间进行协商确定)、 所 述非授权频谱供其他设备使用的预留时间(例如可以是异***的设备以网络配 置向量(NAV, Net Allocation Vector)的方式发送的请求发送(RTS, request to send) 或清除发送 (CTS, clear to send) 帧中所包含的时间信息)、 所述基站 所在***在非授权频谱的静默时间(该静默时间指 LTE***不发送任何信息, 以留给其他***竞争频谱的机会,在此期间, 其他***可能占用频谱或者不占 用频谱。)。当然具体实现中, 用户设备也可直接接收异***的设备以网络配置 向量(NAV, Net Allocation Vector)的方式发送的请求发送(RTS, request to send) 或清除发送 (CTS, clear to send) 帧中所包含的时间信息), 并以接收的时间 信息作为非授权频的释放时间。
方式 3 : 所述用户设备接收基站发送的非授权频谱的释放指示并根据所述 释放指示和预先设置的规则计算所述基站对非授权频谱的释放时间,并将所述 计算出的释放时间与预先设置的时间阈值比较,以确定所述接收的释放时间是 否超过所述预先设置的时间阈值(比如, 基站检测到高优先级设备如雷达占用 了非授权频谱时, 向 UE发送特殊的释放指示, 或者释放指示中包含异***类 型信息,则 UE根据频谱法规获知需要释放较长时间,例如至少 2小时以上。 ) 具体实现中, 本发明的数据处理过程可包括混合自动重传请求 HARQ过 程; 则在步骤 S111 , 所述用户设备暂停依附于所述非授权频谱的数据处理过 程, 包括: 所述用户设备执行依附于所述非授权频谱的如下操作中至少一种: 暂停监听物理下行控制信道、 暂停下行接收、 暂停上行发送、 保留 HARQ缓 冲区、 暂停接收下行 HARQ重传、 暂停接收下行 HARQ反馈信息、 暂停发送 上行 HARQ重传、 暂停发送上行 HARQ反馈信息;
具体实现中,下行接收包括但不限于 PDCCH、物理下行共享信道(PDSCH, physical downlink shared channel ) 上的下行传输块 (TB , transport block )、 物 理混合自动重传指示信道 (PHICH, physical HARQ indication channel) 上的 HARQ反馈信息确认信息 ACK或非确认信息 NACK、主同步信号( PSS, primary synchronization signal )、 辅同步参考信号 (SSS, secondary synchronization ) 小区参考信号( CRS, cell reference signal )、信道状态参考信号( CSI-RS, channel state information reference signal )、 角早调参考信号 ( DMRS, demodulation reference signal)、广播信道(BCH, broadcast channel)上的主***信息块(ΜΙΒ , master information block ) PDSCH上的***信息块 ( system information block ) 多媒体广播多播*** (MBMS, multimedia broadcast multicast system) 相关的 信息等。
具体实现中, 上行发送包括但不限于: 在物理上行控制信道 (PUCCH, physical uplink control channel)上或物理上行共享信道 (PUSCH, physical uplink shared channel ) 上发送上行控制信息 (UCI, uplink control information )、 在 PUSCH上发送传输块、发送上行探测参考信号(SRS, sounding reference signal). 解调参考信号 DMRS、 物理随机接入信道 (PRACH, physical random access channel) 上的前导 (preamble) 等; 其中 UCI信息包括但不限于: HARQ反 馈信息确认信息 ACK或非确认信息 NACK、 信道状态指示 (CQI, channel quality indication ) 予页编石马矩阵指不 (PMI, Pre-coding matrix Indication )、 禾失 指不 (RI, ranking indication )、予页编石马类型指不 (PTI, precoding type indication ) 等。
具体实现中, 如果 LTE释放非授权频谱前 UE接收下行传输块 TB失败, 且 UE未来得及在物理上行控制信道 PUCCH或物理上行共享信道 PUSCH上 发送 HARQ反馈信息 ACK或 NACK,则 LTE释放非授权频谱期间 UE可不发 送 HARQ反馈信息, 不监听物理下行控制信道 PDCCH以接收下行 HARQ重 传。 并且, UE在下行 HARQ软缓冲区(soft buffer)可保留所接收到的下行传 输块的冗余版本(RV, redundancy version), 用于以后合并 LTE重新获取非授 权频谱后基站发送下行传输块的 HARQ重传的冗余版本。
具体实现中, 如果在 LTE释放非授权频谱前 UE发送了上行传输块 TB, 但未来得及接收到基站在物理混合自动重传指示信道 PHICH上发送的 HARQ 反馈信息 ACK或 NACK,则 UE可在 LTE释放非授权频谱期间需要接收 PHICH 的子帧 (subframe) 不接收 PHICH, 且认为 PHICH上的信息为 ACK。 UE保 留上行 HARQ缓冲区中的数据, 用于以后 LTE重新获取到非授权频谱后根据 基站的上行授权(UL grant)进行上行 HARQ重传, 或者根据基站的上行授权 生成新的上行传输块进行发送。
具体实现中,如果在 LTE释放非授权频谱前 UE发送了上行传输块,且接 收到基站在物理混合自动重传指示信道 PHICH 上发送的 HARQ 反馈信息 NACK,则 UE可在 LTE释放非授权频谱期间需要在 PUSCH上进行 HARQ重 传的子帧不进行上行 HARQ重传。 UE保留上行 HARQ缓冲区中的数据, 用 于以后 LTE重新获取到非授权频谱后根据基站的上行授权(UL grant)进行自 适应上行 HARQ重传, 或者进行非自适应 (non adaptive) HARQ重传。

需要说明的是, 本发明实施例所述的 "暂停"可替换为 "挂起"、 "临时取 消"、 "暂时不进行 "等描述, 其表达的意思均是暂时停止依附于所述非授权频 谱的数据处理过程,但是保留已经进行的数据处理过程, 以便后续对数据处理 过程能在已经进行的过程上进行继续。本发明实施例所述的 "恢复"可替换为 "继续"、 "延续"等描述, 其表达的意思均是继续暂停时未完成的数据处理过 程。

所述用户设备选择授权频谱重新开始新的 HARQ处理过程或者在所述基 站重新获取所述非授权频谱后,重新开始新的 HARQ处理过程。比如,以 LTE-A 为例, UE可选择授权频谱上的 PCell或 SCdl发送 LTE释放非授权频谱前未 发送成功的 MAC CE; MAC CE包括但不限于缓冲区状态报告 (BSR, buffer status report)、功率余量报告(PHR, power headroom report )等上行 MAC CE。 当选择授权频谱上的 PCell或 SCell发送上行 MAC CE时, UE重新生成 MAC CE按照新的 HARQ传输进行。 LTE释放非授权频谱前未发送成功的其它传输 块 TB由高层无线链路控制 (RLC, radio link control) 层负责重传或者也可以 选择直接生成新的传输块在授权频谱上的 PCdl或 SCdl进行 HARQ传输。
具体实现中, 本发明的数据处理过程可包括不连续接收 DRX过程; 则在 步骤 S111 ,所述用户设备暂停依附于所述非授权频谱的数据处理过程,包括: 所述用户设备执行依附于所述非授权频谱的如下操作中至少一种: 维持各 DRX定时器的正常运行 (继续运行并当超时后停止)、 维持各 DRX定时器的 正常运行但所述用户设备不进行计时或计数 (继续运行但 DRX定时器的时间 相应延长了非授权频谱释放期间的时间长度)、 暂停监听物理下行控制信道、 暂停下行接收、 暂停上行发送;
具体实现中, 本发明实施例所述的 DRX定时器可包括: 持续时间定时器 (onDurationTimer). 非连续接收非活动时间定时器 (drx-InactivityTimer). 非 连续接收重传定时器(drx-RetransmissionTimer)、 混合自动重传请求环回时间 定时器( HARQ RTT Timer )、非连续接收短周期定时器(drxShortCycleTimer) 等。
具体实现中, 本实施例中暂停监听物理下行控制信道、暂停下行接收、 暂 停上行发送等的处理方式参考对 HARQ的相关处理方式, 在此不进行赘述。 具体实现中, 本发明的数据处理过程可包括不连续接收 DRX过程; 则在 步骤 S111 , 所述用户设备在所述基站重新获取所述非授权频谱后, 恢复所述 数据处理过程, 包括:
所述用户设备执行依附于所述非授权频谱的如下操作中至少一种:在所述 基站重新获取所述非授权频谱后,恢复监听物理下行控制信道、恢复下行接收、 恢复上行发送。
具体实现中, 本实施例中恢复监听物理下行控制信道、恢复下行接收、 恢 复上行发送等的处理方式参考对 HARQ的相关处理方式, 在此不进行赘述。
需要说明的是, 本发明实施例所述的 "暂停"可替换为 "挂起"、 "临时取 消"、 "暂时不进行 "等描述, 其表达的意思均是暂时停止依附于所述非授权频 谱的数据处理过程,但是保留已经进行的数据处理过程, 以便后续对数据处理 过程能在已经进行的过程上进行继续。本发明实施例所述的 "恢复"可替换为 "继续"、 "延续"等描述, 其表达的意思均是继续暂停时未完成的数据处理过 程。
具体实现中, 本发明的数据处理过程可包括不连续接收 DRX过程; 则在 步骤 S112,所述用户设备终止依附于所述非授权频谱的数据处理过程,包括: 所述用户设备执行依附于所述非授权频谱的如下操作中至少一种: 执行 HARQ实体复位操作、执行使用所述非授权频谱的小区的去激活操作、停止所 述各 DRX定时器;
其中, 执行 HARQ实体复位操作、 执行使用所述非授权频谱的小区的去 激活操作的处理方式, 参考对 HARQ的相关处理方式, 在此不进行赘述。
当 ^授权频谱的小区与授权频谱的小区使用相同的 DRX参数配置和 DRX 操作时,所述用户设备终止依附于所述非授权频谱的数据处理过程时, 不停止 所述各 DRX定时器;
当非授权频谱的小区与授权频谱的小区执行不相同的 DRX参数配置时, 所述用户设备终止依附于所述非授权频谱的数据处理过程时, 停止所述各 DRX定时器。
比如, 以 LTE-A为例, 当非授权频谱上的 SCdl执行独立于授权频谱上的 PCell和 SCdl的 DRX操作, 即该 SCdl上的 DRX参数配置和 UE在该 SCdl 上的活动时间独立于授权频谱上的载波的 DRX参数配置和活动时间。 本发明 实施例在步骤 S112, 不停止所述各 DRX定时器。 而当非授权频谱上的 SCdl 执行与授权频谱上的 PCdl和 SCell的共同 DRX操作 (common DRX) , 现有 技术中共同 DRX操作指各 SCdl上的 DRX参数配置重用 PCdl上的 DRX参 数配置, UE在各 SCell和 PCdl上的活动时间规律相同,即激活状态的各 SCdl 和 PCdl要么都处于活动时间 (active time), 要么都处于非活动时间 (inactive time) o 此时, 在步骤 S112, UE对非授权频谱上的 SCdl执行去激活操作或 HARQ复位操作, 但不停止各 DRX定时器, 因为授权频谱上的 PCdl和其他 SCell的 DRX操作的正常进行还需要依赖于这些定时器的运行或停止。
本实施例提供的 DRX处理方法, 可以使 UE根据非授权频谱释放时间的 长短进行相应的处理, 如对 DRX定时器的处理和监听 PDCCH的处理, 使非 授权频谱释放期间和 LTE重新获取非授权频谱后的 DRX操作能够顺利进行或 延续, 以利于 UE在非授权频谱工作时达到更好的省电效果。
具体实现中,本发明实施例的数据处理过程包括自动重传请求 ARQ过程; 则在步骤 S111 , 所述用户设备暂停依附于所述非授权频谱的数据处理过 程, 包括:
所述用户设备执行依附于所述非授权频谱的如下操作中至少一种:挂起无 线链路控制层 RLC的重排序定时器、 挂起轮询重传定时器;
以 LTE-A为例, 在 CA所聚合的各小区由同一个 LTE基站所提供的情况 下, RLC状态报告 (RLC status report )、 设置了轮询位 (poll) 的 RLC协议数 据单元 (PDU)、 需要重传的 RLC PDU等信息可以在授权频谱上的 PCdl或 SCell或者在非授权频谱上的 SCdl进行发送, 因此当 LTE临时释放非授权频 谱后, UE和基站自然可以在授权频谱上的 PCdl或 SCdl上发送上述信息。但 是, 如果 CA所聚合的各小区由不同的 LTE基站所提供的情况下, 如果提供 非授权频谱的小区所在的基站没有配置其它授权频谱,则非授权频谱释放时间 大于一定门限时, UE和基站可以通过另外一个基站所提供的小区进行发送。
在 3GPP小小区增强(SCE, small cell enhancement)项目中, 可以在基站 间进行 CA, 主基站 (MeNB, master eNB ) 提供 PCell和 0至多个 SCdl, 辅 基站 (SeNB, secondary eNB ) 提供 1至多个 SCell, 如果 SeNB配置了上行, 则 SeNB至少一个 SCell需要配置 PUCCH, 该 SCdl为 SeNB上的主小区。 对 于用户面的数据无线承载(data radio bearer),可以仅位于 SeNB上,通过 SeNB 和服务网关(SGW, serving gateway)的 S1-U接口进行通信;可以***(split) 为两个逻辑信道 (logical channel) 通过 MeNB与 UE的无线接口和 SeNB与 UE的无线接口和 UE进行数据传输,通过 MeNB与 SGW的 S1-U接口与网络 进行通信。 如果 SeNB上仅提供了一个主小区, 且该主小区在非授权频谱上, 则 LTE释放非授权频谱后需要对 ARQ过程进行相应的处理。 比如, 如果在 LTE释放非授权频谱之前: UE从 SeNB接收到一个或多个下行 RLC协议数据 单元 (PDU, packet data unit), 但没有来得及向基站发送 RLC状态报告 (RLC status report) 反馈 RLC PDU的接收状态, 包括 RLC PDU接收成功 ACK和 / 或接收失败 NACK的信息; 和 /或 UE向 SeNB发送了一个或多个 RLC PDU, 但还没有接收到 SeNB发送的 RLC状态报告,或者 UE已经接收到了 SeNB发 送的 RLC状态报告, 但未来得及执行 RLC PDU重传, 在这些情况下, 均涉 及非授权频谱释放后的 ARQ处理问题。
具体的, 在步骤 S111 , 对于 RLC接收实体, UE挂起 (suspend) 即暂停 RLC层的重排序定时器 (reordering Timer) (具体实现中, 此处的挂起可以为 暂停运行, 也可以是继续运行定时器但不对定时器进行计时); 对于 RLC发送 实体, 如果 UE已经向 SeNB发送了设置了 Poll位的 RLC PDU并启动了 poll 重传定时器 (poll retransmit Timer) 则挂起 poll重传定时器。 相应的, 基站按 照 UE对应的方法处理相关的定时器。
具体实现中,本发明实施例的数据处理过程包括自动重传请求 ARQ过程; 则在步骤 S111 , 所述用户设备在所述基站重新获取所述非授权频谱后, 恢复所述数据处理过程, 包括:

需要说明的是, 本发明实施例所述的 "恢复"可替换为 "继续"、 "延续" 等描述, 其表达的意思均是继续暂停时未完成的数据处理过程, 比如, 继续运 行定时器, 或者继续对定时器从挂起的时间点计时。
具体实现中,本发明实施例的数据处理过程包括自动重传请求 ARQ过程; 则在步骤 S112, 所述用户设备终止依附于所述非授权频谱的数据处理过 程, 包括:
所述用户设备执行依附于所述非授权频谱的如下操作中至少一种:停止所 述重排序定时器、 停止所述轮询重传定时器;
具体实现中,本发明实施例的数据处理过程包括自动重传请求 ARQ过程; 则在步骤 S112, 所述选择授权频谱重新开始新的数据处理过程或者在所 述基站重新获取所述非授权频谱后, 重新开始新的数据处理过程, 包括:
所述用户设备选择授权频谱重新开始新的 ARQ处理过程或者在所述基站 重新获取所述非授权频谱后, 重新开始新的 ARQ处理过程。 比如, 以 LTE-A 为例, UE可选择 MeNB提供的授权频谱上的 PCdl或 SCell发送和 /或接收 ARQ 的相关信息。
本实施例提供的非授权频谱释放后的 ARQ方法, 可以使 RLC层的 ARQ过 程不因非授权频谱的释放而无法正常进行,避免了因 ARQ重传延迟较大而导致 TCP重传, 从而节省了频谱资源, 提高了***吞吐量。
具体实现中, 本发明实施例的数据处理过程包括随机接入过程;
则在步骤 S111 , 所述用户设备暂停依附于所述非授权频谱的数据处理过 程, 包括:

具体实现中, 本发明实施例的数据处理过程包括随机接入过程;
则在步骤 S111 , 所述用户设备在所述基站重新获取所述非授权频谱后, 恢复所述数据处理过程, 包括:

具体实现中, 本发明实施例的数据处理过程包括随机接入过程; 则在步骤 S112, 所述用户设备终止依附于所述非授权频谱的数据处理过 程, 包括:
所述用户设备执行依附于所述非授权频谱的如下操作中至少一种:停止随 机接入响应窗口及停止等待随机接入响应消息、停止竞争解决定时器及停止等 待竞争解决消息;
具体实现中, 本发明实施例的数据处理过程包括随机接入过程; 则在步骤 S112, 所述用户设备选择授权频谱重新开始新的数据处理过程 或者在所述基站重新获取所述非授权频谱后, 重新开始新的数据处理过程, 包 括:
所述用户设备选择授权频谱重新开始新的随机接入过程或者在所述基站 重新获取所述非授权频谱后,重新开始新的随机接入过程。比如, UE可在 LTE 重新获取到非授权频谱后重新触发随机接入过程,可以利用现有技术由基站通 过 PDCCH触发或者 UE的 MAC层触发。
另外, 具体实现中, 还可能存在如下情形, 如果基站或 UE已经触发了随 机接入过程,如 UE已经发送了随机接入前导,则 LTE始终不释放非授权频谱, 而继续进行随机接入过程, 直至随机接入过程完成; 或者 UE仅针对非基于竞 争 (contention free) 的随机接入过程继续等待到 RAR窗口结束而随机接入完 成或失败后再释放非授权频谱;或者如果本次随机接入尝试失败才释放非授权 频谱, 等到 LTE重新获取到非授权频谱资源后再触发随机接入过程。 在本方 法中, 认为随机接入过程的优先级高于非授权频谱的释放。
具体实现中, 本发明实施例的数据处理过程包括无线资源管理 (RRM, radio resource management ) 测量 ( measurement ) 过禾呈;
则在步骤 S111 , 所述用户设备暂停依附于所述非授权频谱的数据处理过 程, 包括:
所述用户设备暂停所述 RRM测量过程; 具体实现中, RRM测量为基于 CRS或 CSI-RS或基于 DMRS的参考信号接收功率 (RSRP, reference signal received power)禾口 /或参考信号接收质量 RSRQ (reference signal received quality ) 进行测量。 基站为 UE配置了对非授权频谱上的 SCell进行 RRM测量。

当然, 具体实现中, 本发明实施例也可在确定基站释放了非授权频谱后, 始终执行: 暂停依附于所述非授权频谱的数据处理过程, 并在所述基站重新获 取所述非授权频谱后, 恢复所述数据处理过程; 或者, 始终执行: 所述用户设 备终止依附于所述非授权频谱的数据处理过程,并选择授权频谱重新开始新的 数据处理过程或者在所述基站重新获取所述非授权频谱后,重新开始新的数据 处理过程。 而不按照非授权频谱释放时间的长短采用不同的处理方案。
由上可见,在本发明的一些实施例中, 当用户设备确定基站释放了非授权 频谱,所述用户设备监测所述基站对所述非授权频谱的释放时间的长短,所述 释放时间指示所述基站从释放非授权频谱至重新获取所述非授权频谱的时间 间隔; 当所述释放时间未超过时间阈值,所述用户设备暂停依附于所述非授权 频谱的数据处理过程, 并在所述基站重新获取所述非授权频谱后, 恢复所述数 据处理过程,由此保证了重新获取非授权频谱后的通信过程的正常恢复;以及, 当所述释放时间超过所述时间阈值,所述用户设备终止依附于所述非授权频谱 的数据处理过程,并选择授权频谱重新开始新的数据处理过程或者在所述基站 重新获取所述非授权频谱后, 重新开始新的数据处理过程, 由此避免了延迟的 冗余重传而浪费无线资源,避免数据包传输延迟过大而导致的传输控制协议重 传而影响吞吐量或通信失败等。
相应的,本发明实施例公开了可用于实施上述方法实施例的流程的用户设 备。下面结合图 2-图 5对本发明实施例的用户设备的结构组成示意图进行举例 说明。
图 2为本发明的用户设备 (UE) 的一实施例的结构组成示意图。 如图 2 所示,其可包括:监测模块 21、第一处理模块 22以及第二处理模块 23,其中: 监测模块 21, 用于当用户设备确定基站释放了非授权频谱, 监测所述基 站对所述非授权频谱的释放时间的长短,所述释放时间指示所述基站从释放非 授权频谱至重新获取所述非授权频谱的时间间隔;
第一处理模块 22, 用于当所述监测模块 21监测的所述释放时间未超过时 间阈值, 暂停依附于所述非授权频谱的数据处理过程, 并在所述基站重新获取 所述非授权频谱后, 恢复所述数据处理过程;
第二处理模块 23, 用于当所述监测模块 21监测的所述释放时间超过所述 时间阈值, 终止依附于所述非授权频谱的数据处理过程, 并选择授权频谱重新 开始新的数据处理过程或者在所述基站重新获取所述非授权频谱后,重新开始 新的数据处理过程。
具体实现中, 如图 3所示, 可选的, 本发明实施例的用户设备还可包括释 放确定模块 20, 用于在接收到所述基站发送的释放非授权频谱的指示信息时 确定所述基站释放了非授权频谱,或根据所述基站的参数检测到所述基站释放 了所述非授权频谱。 以 LTE-A***为例, 基站获取到非授权频谱后, 基站和 用户设备(UE)通过 SCdl的无线资源进行通信。通信一段时间之后, 基站释 放非授权频谱, 则基站向 UE发送非授权频谱释放指示信息, 上述指示信息可 通过物理下行控制信道 (包括物理下行控制信道 (Physical downlink control channel, PDCCH) 或增强的物理下行控制信道 (enhanced physical downlink control channel, EPDCCH ) )发送,或者,通过媒体接入层控制控制元素(Medium access control control element, MAC CE)发送。这样当 UE的释放确定模块 20 接收到基站通过 PDCCH或 EPDCCH或 MAC CE发送的释放非授权频谱的指 示信息时, 便可确定所述基站释放了非授权频谱。 或者, UE的释放确定模块 20通过对 LTE参考信号的测量检测到基站释放了非授权频谱。
具体实现中,如图 4所示,所述监测模块 21,可包括:第一监测模块 211、 第二监测模块 212以及第三监测模块 213中任一种,
第一监测模块 211, 用于启动一个等待时间定时器用于记录所述基站对非 授权频谱的释放时间的长短, 当所述等待时间定时器未超时,确定所述释放时 间未超过所述时间阈值, 当所述等待时间定时器超时后,确定所述释放时间超 过所述时间阈值。 仍以 LTE-A***为例, 当 UE确定基站释放了非授权频谱 后, 通过第一监测模块 211启动等待时间定时器 (可记为: wait-timer) , 用于 记录所述基站对非授权频谱的释放时间的长短,若在 UE接收到基站发送的重 新获取到非授权频谱的指示之前或者 UE未检测到基站重新获取了非授权频谱 均说明非授权频谱还处于释放时间段内, 由此, 本发明实施例, 当在基站重新 获取到非授权频谱并指示 UE之前或者 UE重新检测到基站获取了非授权频谱 之前 (说明非授权频谱的释放时间在继续), 若等待时间定时器未超时, 确定 所述释放时间未超过时间阈值; 而当在基站重新获取到非授权频谱并指示 UE 之前或者 UE重新检测到基站获取了非授权频谱之前(说明非授权频谱的释放 时间在继续), 若等待定时器超时, 确定所述释放时间超过时间阈值。 在该方 式中, 等待定时器的超时时间点即为所述时间阈值。具体实现中, 等待时间定 时器可以是单独的定时器, 或者重用现有技术的去激活定时器
( sCellDeactivationTimer) , UE接收到基站的释放非授权频谱指示或者自己检 测到非授权频谱释放, 可以启动或重新启动去激活定时器, 或者如果去激活定 时器已经运行, 则继续维持去激活定时器; 在去激活定时器超时前, 确定释放 时间未超过时间阈值, 当去激活定时器超时后,确定释放时间超过所述时间阈 值。
第二监测模块 212, 用于接收基站发送的具体的非授权频谱的释放时间, 并将所述接收的释放时间与预先设置的时间阈值比较,以确定所述接收的释放 时间是否超过所述预先设置的时间阈值。具体实现中,所述具体的非授权频谱 的释放时间至少包括如下时间中的一种:所述非授权频谱被其他设备占用的时 间(比如, 基站检测到高优先级设备如雷达占用了非授权频谱时, 将雷达占用 非授权频谱的时间发送给 UE)、所述非授权频谱的释放和获取的间隔周期(例 如周期信息可以是规律性的子帧模式 (subframe pattern)信息, 表示释放到下 一次获取到频谱之间的时间间隔, 该规律是周期性的。所述周期由共享非授权 频谱的***之间进行协商确定)、 所述非授权频谱供其他设备使用的预留时间 (例如可以是异***的设备以网络配置向量 (NAV, Net Allocation Vector) 的 方式发送的请求发送 (RTS, request to send)或清除发送(CTS, clear to send) 帧中所包含的时间信息)、 所述基站所在***在非授权频谱的静默时间 (该静 默时间指 LTE***不发送任何信息, 以留给其他***竞争频谱的机会, 在此 期间, 其他***可能占用频谱或者不占用频谱。)。 当然具体实现中, 用户设备 也可直接接收异***的设备以网络配置向量 (NAV, Net Allocation Vector) 的 方式发送的请求发送 (RTS, request to send)或清除发送(CTS, clear to send) 帧中所包含的时间信息), 并以接收的时间信息作为非授权频的释放时间。
第三监测模块 213, 用于接收基站发送的非授权频谱的释放指示, 并根据 所述释放指示和预先设置的规则计算所述基站对非授权频谱的释放时间,并将 所述计算出的释放时间与预先设置的时间阈值比较,以确定所述接收的释放时 间是否超过所述预先设置的时间阈值(比如, 基站检测到高优先级设备如雷达 占用了非授权频谱时, 向 UE发送特殊的释放指示, 或者释放指示中包含异系 统类型信息, 则 UE根据频谱法规获知需要释放较长时间, 例如至少 2小时以 上。)
具体实现中, 本发明的所述数据处理过程包括混合自动重传请求 HARQ 过程;则所述第一处理模块 22具体用于在所述监测模块 21监测的所述释放时 间未超过时间阈值时, 执行依附于所述非授权频谱的如下操作中至少一种: 暂 停监听物理下行控制信道、 暂停下行接收、 暂停上行发送、 保留 HARQ缓冲 区、 暂停接收下行 HARQ重传、 暂停接收下行 HARQ反馈信息、 暂停发送上 行 HARQ重传、 暂停发送上行 HARQ反馈信息; 以及, 在所述基站重新获取 所述非授权频谱后, 执行依附于所述非授权频谱的如下操作中至少一种: 恢复 监听物理下行控制信道、恢复下行接收、恢复上行发送、恢复接收下行 HARQ 重传、 恢复接收下行 HARQ反馈信息、 恢复发送上行 HARQ重传、 恢复发送 上行 HARQ反馈信息。

具体实现中, 上行发送包括但不限于: 在物理上行控制信道 (PUCCH, physical uplink control channel)上或物理上行共享信道 (PUSCH, physical uplink shared channel ) 上发送上行控制信息 (UCI, uplink control information )、 在 PUSCH上发送传输块、发送上行探测参考信号(SRS, sounding reference signal). 解调参考信号 DMRS、 物理随机接入信道 (PRACH, physical random access channel) 上的前导 (preamble) 等; 其中 UCI信息包括但不限于: HARQ反 馈信息确认信息 ACK或非确认信息 NACK、 信道状态指示 (CQI, channel quality indication )、 予页编石马矩阵指不 (ΡΜΙ, Pre-coding matrix Indication )、 禾失 指不 (RI, ranking indication )、予页编石马类型指不 (PTI, precoding type indication ) 等。
具体实现中, 如果 LTE释放非授权频谱前 UE接收下行传输块 TB失败, 且 UE未来得及在物理上行控制信道 PUCCH或物理上行共享信道 PUSCH上 发送 HARQ反馈信息 ACK或 NACK,则 LTE释放非授权频谱期间 UE可不发 送 HARQ反馈信息, 不监听物理下行控制信道 PDCCH以接收下行 HARQ重 传。 并且, UE在下行 HARQ软缓冲区(soft buffer)可保留所接收到的下行传 输块的冗余版本(RV, redundancy version), 用于以后合并 LTE重新获取非授 权频谱后基站发送下行传输块的 HARQ重传的冗余版本。
具体实现中, 如果在 LTE释放非授权频谱前 UE发送了上行传输块 TB, 但未来得及接收到基站在物理混合自动重传指示信道 PHICH上发送的 HARQ 反馈信息 ACK或 NACK,则 UE可在 LTE释放非授权频谱期间需要接收 PHICH 的子帧 (subframe) 不接收 PHICH, 且认为 PHICH上的信息为 ACK。 UE保 留上行 HARQ缓冲区中的数据, 用于以后 LTE重新获取到非授权频谱后根据 基站的上行授权(UL grant)进行上行 HARQ重传, 或者根据基站的上行授权 生成新的上行传输块进行发送。
具体实现中,如果在 LTE释放非授权频谱前 UE发送了上行传输块,且接 收到基站在物理混合自动重传指示信道 PHICH 上发送的 HARQ 反馈信息 NACK,则 UE可在 LTE释放非授权频谱期间需要在 PUSCH上进行 HARQ重 传的子帧不进行上行 HARQ重传。 UE保留上行 HARQ缓冲区中的数据, 用 于以后 LTE重新获取到非授权频谱后根据基站的上行授权(UL grant)进行自 适应上行 HARQ重传, 或者进行非自适应 (non adaptive) HARQ重传。
具体实现中, 以通过等待定时器监测非授权频谱的释放时间的长短为例, 若在等待时间定时器超时前, UE接收到基站发送的非授权频谱获取指示或同 步指示信息 (也即所述基站重新获取所述非授权频谱), 或者 UE 自己检测到 LTE重新获取到非授权频谱,则 UE的第一处理模块 22停止等待时间定时器, 并监听 PDCCH、 进行下行接收和上行发送、 继续或延续在释放非授权频谱前 的 HARQ操作, 例如接收基站发送的下行 HARQ重传或新的 TB块、 接收基 站发送的上行授权进行上行 HARQ重传或生成新的 TB块进行上行传输或者进 行上行非自适应 HARQ重传。
需要说明的是, 本发明实施例所述的 "暂停"可替换为 "挂起"、 "临时取 消"、 "暂时不进行 "等描述, 其表达的意思均是暂时停止依附于所述非授权频 谱的数据处理过程,但是保留已经进行的数据处理过程, 以便后续对数据处理 过程能在已经进行的过程上进行继续。本发明实施例所述的 "恢复"可替换为 "继续"、 "延续"等描述, 其表达的意思均是继续暂停时未完成的数据处理过 程。

具体实现中, 所述数据处理过程包括不连续接收 DRX过程;
所述第一处理模块 22, 具体用于在所述监测模块 21监测的所述释放时间 未超过时间阈值时, 执行依附于所述非授权频谱的如下操作中至少一种: 维持 各 DRX定时器的正常运行(继续运行并当超时后停止)、 维持各 DRX定时器 的正常运行但所述用户设备不进行计时或计数 (继续运行但 DRX定时器的时 间相应延长了非授权频谱释放期间的时间长度 )、暂停监听物理下行控制信道、 暂停下行接收、暂停上行发送;以及,在所述基站重新获取所述非授权频谱后, 执行依附于所述非授权频谱的如下操作中至少一种:在所述基站重新获取所述 非授权频谱后, 恢复监听物理下行控制信道、 恢复下行接收、 恢复上行发送。

具体实现中, 本实施例中恢复监听物理下行控制信道、恢复下行接收、 恢 复上行发送等的处理方式参考对 HARQ的相关处理方式, 在此不进行赘述。 需要说明的是, 本发明实施例所述的 "暂停"可替换为 "挂起"、 "临时取 消"、 "暂时不进行 "等描述, 其表达的意思均是暂时停止依附于所述非授权频 谱的数据处理过程,但是保留已经进行的数据处理过程, 以便后续对数据处理 过程能在已经进行的过程上进行继续。本发明实施例所述的 "恢复"可替换为 "继续"、 "延续"等描述, 其表达的意思均是继续暂停时未完成的数据处理过 程。
具体实现中, 所述数据处理过程包括不连续接收 DRX过程;
所述第二处理模块 23具体用于当所述监测模块 21监测的所述释放时间超 过所述时间阈值时, 执行依附于所述非授权频谱的如下操作中至少一种: 执行 HARQ实体复位操作、执行使用所述非授权频谱的小区的去激活操作、停止所 述各 DRX定时器, 以及, 选择授权频谱重新开始新的 DRX处理过程或者维 持授权频谱正在进行的 DRX处理过程或者在所述基站重新获取所述非授权频 谱后, 重新开始新的 DRX处理过程。
其中, 执行 HARQ实体复位操作、 执行使用所述非授权频谱的小区的去 激活操作的处理方式, 参考对 HARQ的相关处理方式, 在此不进行赘述。
具体实现中, 当非授权频谱的小区与授权频谱的小区使用相同的 DRX参 数配置和 DRX操作时,所述第二处理模块 23终止依附于所述非授权频谱的数 据处理过程时, 不停止所述各 DRX定时器;
当非授权频谱的小区与授权频谱的小区执行不相同的 DRX参数配置时, 所述第二处理模块 23终止依附于所述非授权频谱的数据处理过程时, 停止所 述各 DRX定时器。
比如, 以 LTE-A为例, 当非授权频谱上的 SCdl执行独立于授权频谱上的 PCdl和 SCdl的 DRX操作, 即该 SCdl上的 DRX参数配置和 UE在该 SCdl 上的活动时间独立于授权频谱上的载波的 DRX参数配置和活动时间。 本发明 实施例第二处理模块 23不停止所述各 DRX定时器。而当非授权频谱上的 SCdl 执行与授权频谱上的 PCdl和 SCell的共同 DRX操作 (common DRX) , 现有 技术中共同 DRX操作指各 SCdl上的 DRX参数配置重用 PCdl上的 DRX参 数配置, UE在各 SCdl和 PCdl上的活动时间规律相同,即激活状态的各 SCdl 和 PCdl要么都处于活动时间 (active time), 要么都处于非活动时间 (inactive time) o 此时, 第二处理模块 23 对非授权频谱上的 SCdl 执行去激活操作或 HARQ复位操作, 但不停止各 DRX定时器, 因为授权频谱上的 PCdl和其他 SCdl的 DRX操作的正常进行还需要依赖于这些定时器的运行或停止。
本实施例提供的 DRX处理方案, 可以使 UE根据非授权频谱释放时间的 长短进行相应的处理, 如对 DRX定时器的处理和监听 PDCCH的处理, 使非 授权频谱释放期间和 LTE重新获取非授权频谱后的 DRX操作能够顺利进行或 延续, 以利于 UE在非授权频谱工作时达到更好的省电效果。
具体实现中, 所述数据处理过程包括自动重传请求 ARQ过程;
所述第一处理模块 22具体用于在所述监测模块 21监测的所述释放时间未 超过时间阈值时, 执行依附于所述非授权频谱的如下操作中至少一种: 挂起无 线链路控制层 RLC的重排序定时器、 挂起轮询重传定时器; 以及, 在所述基 站重新获取所述非授权频谱后,执行依附于所述非授权频谱的如下操作中至少 一种: 恢复无线链路控制层的重排序定时器, 并在所述重排序定时器超时后触 发 RLC状态报告; 恢复轮询重传定时器, 并在所述轮询重传定时器超时后触 发设置了轮询位的 RLC数据单元重传或发送新的 RLC数据单元。
以 LTE-A为例, 在 CA所聚合的各小区由同一个 LTE基站所提供的情况 下, RLC状态报告 (RLC status report )、 设置了轮询位 (poll) 的 RLC协议数 据单元 (PDU)、 需要重传的 RLC PDU等信息可以在授权频谱上的 PCdl或 SCdl或者在非授权频谱上的 SCdl进行发送, 因此当 LTE临时释放非授权频 谱后, UE和基站自然可以在授权频谱上的 PCdl或 SCdl上发送上述信息。但 是, 如果 CA所聚合的各小区由不同的 LTE基站所提供的情况下, 如果提供 非授权频谱的小区所在的基站没有配置其它授权频谱,则非授权频谱释放时间 大于一定门限时, UE和基站可以通过另外一个基站所提供的小区进行发送。
在 3GPP小小区增强(SCE, small cell enhancement)项目中, 可以在基站 间进行 CA, 主基站 (MeNB, master eNB ) 提供 PCell和 0至多个 SCdl, 辅 基站 (SeNB, secondary eNB ) 提供 1至多个 SCell, 如果 SeNB配置了上行, 则 SeNB至少一个 SCell需要配置 PUCCH, 该 SCdl为 SeNB上的主小区。 对 于用户面的数据无线承载(data radio bearer),可以仅位于 SeNB上,通过 SeNB 和服务网关(SGW, serving gateway)的 S1-U接口进行通信;可以***(split) 为两个逻辑信道 (logical channel) 通过 MeNB与 UE的无线接口和 SeNB与 UE的无线接口和 UE进行数据传输,通过 MeNB与 SGW的 S1-U接口与网络 进行通信。 如果 SeNB上仅提供了一个主小区, 且该主小区在非授权频谱上, 则 LTE释放非授权频谱后需要对 ARQ过程进行相应的处理。 比如, 如果在 LTE释放非授权频谱之前: UE从 SeNB接收到一个或多个下行 RLC协议数据 单元 (PDU, packet data unit), 但没有来得及向基站发送 RLC状态报告 (RLC status report) 反馈 RLC PDU的接收状态, 包括 RLC PDU接收成功 ACK和 / 或接收失败 NACK的信息; 和 /或 UE向 SeNB发送了一个或多个 RLC PDU, 但还没有接收到 SeNB发送的 RLC状态报告,或者 UE已经接收到了 SeNB发 送的 RLC状态报告, 但未来得及执行 RLC PDU重传, 在这些情况下, 均涉 及非授权频谱释放后的 ARQ处理问题。
具体的, 对于 RLC接收实体, 第一处理模块 22可挂起 (suspend) 即暂停 RLC层的重排序定时器 (reordering Timer) (具体实现中, 此处的挂起可以为 暂停运行, 也可以是继续运行定时器但不对定时器进行计时); 对于 RLC发送 实体, 如果 UE已经向 SeNB发送了设置了 Poll位的 RLC PDU并启动了 poll 重传定时器 (poll retransmit Timer)则第一处理模块 22可挂起 poll重传定时器。 相应的, 基站按照 UE对应的方法处理相关的定时器。
需要说明的是, 本发明实施例所述的 "恢复"可替换为 "继续"、 "延续" 等描述, 其表达的意思均是继续暂停时未完成的数据处理过程, 比如, 继续运 行定时器, 或者继续对定时器从挂起的时间点计时。
具体实现中, 所述数据处理过程包括自动重传请求 ARQ过程;
所述第二处理模块 23具体用于当所述监测模块 21监测的所述释放时间超 过所述时间阈值时, 执行依附于所述非授权频谱的如下操作中至少一种: 停止 所述重排序定时器、 停止所述轮询重传定时器; 以及, 选择授权频谱重新开始 新的 ARQ处理过程或者在所述基站重新获取所述非授权频谱后, 重新开始新 的 ARQ处理过程。 比如, 以 LTE-A为例, 对于重新开始新的 ARQ处理过程 时, 第二处理模块 23可选择 MeNB提供的授权频谱上的 PCdl或 SCell发送 和 /或接收 ARQ的相关信息。
本实施例提供的非授权频谱释放后的 ARQ处理方案, 可以使 RLC层的 ARQ过程不因非授权频谱的释放而无法正常进行, 避免了因 ARQ重传延迟较 大而导致 TCP重传, 从而节省了频谱资源, 提高了***吞吐量。
具体实现中, 所述数据处理过程包括随机接入过程;
所述第一处理模块 22, 具体用于在所述监测模块 21监测的所述释放时间 未超过时间阈值时, 执行依附于所述非授权频谱的如下操作中至少一种: 挂起 随机接入响应窗口 (即暂停对随机接入响应 (RAR, random access response) 窗口的子帧进行计数)、挂起竞争解决定时器(即暂停对竞争解决定时器计数); 以及,在所述基站重新获取所述非授权频谱后, 执行依附于所述非授权频谱的 如下操作中至少一种: 恢复随机接入响应窗口 (即继续从暂停点开始计数)、 恢复竞争解决定时器的运行 (即继续从暂停点开始计数)。
具体的, 如果 UE在等待随机接入响应 (RAR, random access response) 期 间, UE的第一处理模块 22可挂起 (suspend) RAR窗口 (window) , 即暂停对 RAR窗口的子帧进行计数;如果 UE在等待竞争解决(CR, contention resolution) 消息即随机接入过程消息 4 (msg4), 并启动了竞争解决定时器 (contention resolution timer) , 则 UE的第一处理模块 22可暂时挂起竞争解决定时器, 即暂 停对该定时器的计数。
具体实现中, 所述数据处理过程包括随机接入过程,
所述第二处理模块 23具体用于当所述监测模块 21监测的所述释放时间超 过所述时间阈值时, 执行依附于所述非授权频谱的如下操作中至少一种: 停止 随机接入响应窗口及停止等待随机接入响应消息、停止竞争解决定时器及停止 等待竞争解决消息; 以及, 选择授权频谱重新开始新的随机接入过程或者在所 述基站重新获取所述非授权频谱后, 重新开始新的随机接入过程。 比如, 在重 新开始新的随机接入过程时, UE的第二处理模块 23可在 LTE重新获取到非 授权频谱后重新触发随机接入过程,可以利用现有技术由基站通过 PDCCH触 发或者 UE的 MAC层触发。
具体实现中, 所述数据处理过程包括无线资源管理 RRM测量过程; 所述第一处理模块 22, 具体用于在所述监测模块 21监测的所述释放时间 未超过时间阈值时, 暂停所述 RRM测量过程; 以及, 在所述基站重新获取所 述非授权频谱后, 恢复所述 RRM测量过程。 具体实现中, RRM测量为基于 CRS或 CSI-RS或基于 DMRS的参考信号接收功率 (RSRP, reference signal received power)禾口 /或参考信号接收质量 RSRQ (reference signal received quality ) 进行测量。 基站为 UE配置了对非授权频谱上的 SCell进行 RRM测量。
具体实现中, 所述数据处理过程包括无线资源管理 RRM测量过程; 所述第二处理模块 23具体用于当所述监测模块 21监测的所述释放时间超 过所述时间阈值时, 释放所述 RRM测量参数; 以及, 选择授权频谱重新开始 新的 RRM测量过程或者在所述基站重新获取所述非授权频谱后, 重新开始新 的 RRM过程。
具体实现中, 所述数据处理过程包括信道状态信息 CSI测量过程; 所述第一处理模块 22, 具体用于在所述监测模块 21监测的所述释放时间 未超过时间阈值时, 暂停所述 CSI测量过程; 以及, 在所述基站重新获取所述 非授权频谱后, 恢复所述 CSI测量过程。 具体实现中, 本发明实施例的 CSI 测量为基于 CRS或 CSI-RS或基于 DMRS的信道状态测量, 包括 CQI、 PMI、 RI、 PTI等。 基站为 UE配置了对非授权频谱上的 SCell进行 CSI测量。
具体实现中, 所述数据处理过程包括信道状态信息 CSI测量过程; 所述第二处理模块 23具体用于当所述监测模块 21监测的所述释放时间超 过所述时间阈值时, 释放所述 CSI测量参数; 以及, 选择授权频谱重新开始新 的 CSI 测量过程或者在所述基站重新获取所述非授权频谱后, 重新开始新的 CSI过程。
当然, 具体实现中, 本发明实施例也可在确定基站释放了非授权频谱后, 始终通过第一处理模块 22执行:暂停依附于所述非授权频谱的数据处理过程, 并在所述基站重新获取所述非授权频谱后, 恢复所述数据处理过程; 或者, 始 终通过第二处理模块 23执行: 所述用户设备终止依附于所述非授权频谱的数 据处理过程,并选择授权频谱重新开始新的数据处理过程或者在所述基站重新 获取所述非授权频谱后, 重新开始新的数据处理过程。而不按照非授权频谱释 放时间的长短采用不同的处理方案。
由上可见,在本发明的一些实施例中, 当用户设备确定基站释放了非授权 频谱,所述用户设备监测所述基站对所述非授权频谱的释放时间的长短,所述 释放时间指示所述基站从释放非授权频谱至重新获取所述非授权频谱的时间 间隔; 当所述释放时间未超过时间阈值,所述用户设备暂停依附于所述非授权 频谱的数据处理过程, 并在所述基站重新获取所述非授权频谱后, 恢复所述数 据处理过程,由此保证了重新获取非授权频谱后的通信过程的正常恢复;以及, 当所述释放时间超过所述时间阈值,所述用户设备终止依附于所述非授权频谱 的数据处理过程,并选择授权频谱重新开始新的数据处理过程或者在所述基站 重新获取所述非授权频谱后, 重新开始新的数据处理过程, 由此避免了延迟的 冗余重传而浪费无线资源,避免数据包传输延迟过大而导致的传输控制协议重 传而影响吞吐量或通信失败等。
