18iuu2iye> 一种选择物理上行共享信道的方法及用户设备
技术领域
本发明涉及无线通信领域， 特别是涉及一种选择物理上行共享信道的方 法及用户设备。 背景技术
在第三代合作伙伴计划长期演进系统 （ The 3rd Generation Partnership Project Long Term Evolution, 简称 3 GPP LTE )中，用户设备 ( User Equipment, 简称 UE )向基站（ eNodeB, 简称 eNB )发送的上行控制信息（ Uplink Control Information, 简称 UCI )包括：对物理下行共享信道 ( Physical Downlink Shared Channel , 简称 PDSCH ) 的正确 /错误应答消息 （Acknowledgement/Negative Acknowledgement, 简称 ACK/NACK ) , 下行信道的信道状态信息 （Channel State Information, 简称 CSI )等。
其中， UE根据下行参考信号 （reference signal )获得下行信道的信道状 态信息 CSI, 然后， 将获得的 CSI报告给基站。 基站根据 UE反馈的 CSI, 确 定发送给 UE的数据调制编码方式和物理资源位置， 以及传输模式。 LTE系 统中， CSI包括三种形式： 信道质量指示 （ Channels Quality Indication, 简称 CQI ) 、 预编码矩阵指示 （ Pre-coding Matrix Indicator, 简称 PMI ) 、 秩指示 ( Rank Indicator, 简称 RI ) 。
LTE 系统中， ACK/NACK应答消息可以在物理上行控制信道（Physical Uplink Control, 简称 PUCCH )上传输， 也可以在物理上行共享信道（ Physical Uplink Shared Channel, 简称 PUSCH )上传输。 某个子帧 （ subframe )上， 如 果 UE没有发送 PUSCH, ACK/NACK应答消息在 PUCCH上传输； 如果 UE 发送 PUSCH, ACK/NACK应答消息承载在 PUSCH上传输。
LTE系统中，UE对下行信道的 CSI报告有周期反馈和非周期反馈两种方 式， 分别称为周期信道状态信息 ^艮告 ( periodic CSI reporting )和非周期信道 状态信息报告 ( aperiodic CSI reporting ) 。 其中， 对于周期反馈的 CSI, 某个 子帧上， 如果 UE没有发送 PUSCH, CSI在 PUCCH上传输； 如果 UE发送 PUSCH, CSI承载在 PUSCH上传输。 对于非周期反馈的 CSI, 只在 PUSCH 上传输。
LTE系统中， 基站通过上行调度授权（ Uplink grant, 简称 UL grant )信 令调度某个 UE的 PUSCH传输。 上行调度授权信令可由具有下行控制信息 ( Downlink Control Information, 简称 DCI )格式 0 ( format 0 ) 的物理下行控 制信道（ Physical Downlink Control Channel, 简称 PDCCH )发送给所调度的 UE。 DCI format 0中有 1比特用于触发 UE进行非周期 CSI报告， 称为信道 质量指示请求（CQI request ) 。
如果 UE检测到属于它的具有 DCI format 0格式的 PDCCH, 则根据其中 包含的 UL grant发送 PUSCH。 如果 UE检测到 DCI format 0中的 1比特 CQI request置为 T , 则在该 DCI format 0所调度的 PUSCH中发送非周期反馈 的 CSI。
LTE系统中， 还定义了一种特殊的 DCI format 0, 专门用于触发非周期 CSI报告， 而所调度的 PUSCH 中不传输承载上行共享信道（Uplink Shared Channel, 简称 UL-SCH ) 的传输块（ Transport Block, 简称 TB ) 。
需要指出的是， 一般的 PUSCH 均由相应的 UL grant 动态调度 ( Dynamically Scheduled ) 。 但有些特殊的 PUSCH, 比如， 非自适应重传 ( non-adaptive retransmission ) PUSCH , 半持续调度 ( Semi-Persistently Scheduled, 简称 SPS )的 PUSCH, 并没有——对应的 UL grant进行调度， 而 是根据之前的某个 UL grant发送的， 比如， 非自适应重传的 PUSCH是根据 首次传输（ initial transmission ) 的 UL grant发送的， 而半持续调度的 PUSCH 是根据激活半持续调度 ( Semi-Persistent Scheduling Activation )的 UL grant发 送的。 因为没有——对应的 UL grant进行调度，也就无法通过 CQI request信 令触发新的非周期 CSI报告。 LTE系统中， 动态调度 PUSCH的 PDCCH的有 效载荷（ PDCCH payload )的循环冗余校验 ( Cyclic Redundancy Check, 简称 CRC )比特由小区无线网络临时标识（ Cell-Radio Network Temporary Identifier, 简称 C-RNTI )加扰， 而激活半持续调度的 PUSCH的 PDCCH的有效载荷的 CRC 比特由半持续调度小区无线网络临时标识 （Semi-Persistent Scheduling Cell-Radio Network Temporary Identifier, 简称 SPS C-RNTI )加扰。 另外， 一类特殊的上行调度授权信令 UL grant, 称为随机接入响应授权 ( Random Access Response Grant, 简称 RAR grant )信令承载于 PDSCH中发 送给对应的发起随机接入的 UE。 在基于非竟争的随机接入过程 ( non-contention based random access procedure )中 , RAR grant中也包含有 lbit CQI request, 用于触发非周期 CSI报告。 如果发起随机接入的 UE检测到属 于它的 RAR grant, 则据此发送 PUSCH, 该 PUSCH称为首次调度上行传输 ( First scheduled UL transmission, 在随机接入过程中又称为 Message 3 , Msg.3 ) 。 如果 UE检测到 RAR grant中的 1比特 CQI request置为 'Γ , 则 在 Msg.3中发送非周期反馈的 CSI。 在基于竟争的随机接入过程 ( contention based random access procedure ) 中 , RAR grant中的 lbit CQI request保留, 不 用于触发非周期 CSI 4艮告。
高级长期演进（ LTE-Advanced , 简称 LTE-A )系统是 LTE系统的下一代 演进系统，釆用载波聚合（Carrier Aggregation, 简称 CA )技术扩展传输带宽， 支持更大的峰值传输速率。 图 1是根据相关技术的 LTE-A系统载波聚合示意 图。如图 1所示，每个聚合的载波称为一个 "分量载波" （ Component Carrier, 简称 CC ) 。 多个分量载波可以位于同一频段（frequency band ) , 也可以位 于不同频段。
LTE-A系统中， 基站可以对同一用户设备在多个分量载波上分别发送多 个 PDSCH。 根据现有技术， 对 PDSCH的 ACK/NACK应答消息， 周期反馈 的 CSI可以在一个用户设备特定（ UE specific )的分量载波上通过 PUCCH发 送。 所述用户设备特定的分量载波是半静态配置的， 又称为这个用户设备的 主分量载波 ( Primary Component Carrier, 简称 PCC )或主小区 ( Primary cell, 简称 Pcell ) 。 而配置给该用户设备的其余分量载波称为这个用户设备的从分 量载波 ( Secondary Component Carrier, 简称 SCC )或从小区 ( Secondary cell, 简称 Scell )。 通常认为， PCC的信道质量较好。 用户设备只能在其主分量载 波上发送 PUCCH 以及 SPS PUSCH, 而不能在其从分量载波 SCC上发送 PUCCH或 SPS PUSCH。
LTE-A 系统中， 用户设备可以在多个分量载波上分别同时发送多个 PUSCH。 根据现有技术， UCI (至少包括 ACK/NACK应答消息， 周期和非周 期反馈的 CSI )可以在任意一个 PUSCH上传输。 但一个子帧上， UCI最多承 载在一个 PUSCH上。 因此， 某个子帧上， 如果用户设备发送多个 PUSCH, 且有 UCI需要承载在 PUSCH上传输时，用户设备需要在多个 PUSCH中选择 一个 PUSCH用于承载 UCI。
需要指出的是， UCI是在 PUCCH还是在 PUSCH上传输， 或是部分 UCI 在 PUCCH上传输，部分在 PUSCH上传输，是根据具体的场景确定的。比如， 非周期反馈的 CSI只能在 PUSCH上传输； 周期反馈的 CSI以及 ACK/NACK 应答消息当没有 PUSCH发送时， 在 PUCCH上传输， 当有 PUSCH发送时， 根据系统配置， 在 PUCCH上传输和 /或在 PUSCH上传输。 本发明关注的是， 有 UCI (包括该子帧上需要反馈的全部或部分 UCI )需要承载在 PUSCH上传 输的场景。
在设计选择承载 UCI的 PUSCH的方法时， 需要考虑如下因素： 考虑到接收复杂度， 基站需要明确用户设备在哪一个 PUSCH上承载 UCI, 因此， 在选择 PUSCH时， 应使基站和用户设备对在哪一个 PUSCH上 承载 UCI有一致的理解， 避免出现偏差和模糊。
由于 UCI的重要性， 在选择 PUSCH时， 需保证 UCI的传输性能。
由于 UCI承载在 PUSCH上会对原本由 PUSCH发送的上行数据造成影 响， 在选择 PUSCH时， 应在保证性能的前提下， 尽可能减少对数据的影响。
比如， 如果基站预估到用户设备会在某个动态调度的 PUSCH上承载
UCI, 则基站在调度该 PUSCH 时， 可以进行相应的配置和调整， 从而保证 UCI的传输性能， 同时减少对上行数据的影响。
综上， 用户设备如何在多个 PUSCH中选择一个 PUSCH用于承载 UCI, 成为一个亟待解决的问题。 发明内容

附图概述
图 1是 LTE-A系统载波聚合示意图；
图 2是一种选择物理上行共享信道的方法示意图。
本发明的较佳实施方式
选择物理上行共享信道的用户设备包括物理上行共享信道选择模块。 物理上行共享信道选择模块用于根据物理上行共享信道的优先级在一子 帧上发送的多个物理上行共享信道中选择优先级最高的物理上行共享信道用 于承载上行控制信息。
物理上行共享信道的优先级由以下因素中的一个或多个决定： 物理上行 共享信道所在分量载波的优先级、 是否为动态调度的物理上行共享信道、 是 否为触发了非周期信道状态信息（ CSI )报告的上行调度授权信令所调度的物 理上行共享信道。
所述触发了非周期信道状态信息（ CSI )报告的上行调度授权信令所调度 的物理上行共享信道也可以描述为承载非周期状态信息的物理上行共享信 道。
如图 2所示， 当某个用户设备在一个子帧上发送多个 PUSCH, 且有 UCI 需要承载在 PUSCH上传输时，选择物理上行共享信道的方法包括：步骤 201 : 用户设备根据物理上行共享信道的优先级在一子帧上发送的多个物理上行共 享信道中选择优先级最高的物理上行共享信道用于承载上行控制信息。
物理上行共享信道的优先级由以下因素中的一个或多个决定： 物理上行 共享信道所在分量载波的优先级、 是否为动态调度的物理上行共享信道、 是 否为触发了非周期信道状态信息 ( CSI )报告的上行调度授权信令所调度的物 理上行共享信道。 其中， 分量载波的优先级是由高层信令配置的。 或者， 分量载波的优先 级由分量载波的分量载波索引号 （ Component Carrier index, 简称 CC index ) 指示。优选地，分量载波索引号越小，优先级越高。或者， 主分量载波（PCC ) 的优先级最高， 即主分量载波（PCC ) 的优先级高于从分量载波（SCC ) 的 优先级。 从分量载波 SCC的优先级由从分量载波的分量载波索引号指示。 优 选地， 分量载波索引号越小， 优先级越高。
例如， 动态调度的物理上行共享信道的优先级高于非动态调度的物理上 行共享信道的优先级。 所述动态调度的 PUSCH是指有相应上行调度授权信令调度的 PUSCH, 即有相应 PDCCH调度的 PUSCH, 所述非动态调度的 PUSCH是指没有相应 上行调度授权信令调度的 PUSCH, 即没有相应 PDCCH调度的 PUSCH。 优 选地， 所述动态调度的 PUSCH包括激活半持续调度的 PUSCH的 PDCCH所 调度中的自适应重传的 PUSCH。
或者， 所述动态调度的 PUSCH是指用于调度所述 PUSCH的 PDCCH的 有效载荷的 CRC校验比特由 C-RNTI加扰。优选地，所述动态调度的 PUSCH 不包括半持续调度的 PUSCH和非自适应重传的 PUSCH。
例如， 触发了非周期信道状态信息报告的上行调度授权信令所调度的物 理上行共享信道的优先级高于不满足该条件的其它物理上行共享信道的优先 级。
例如， 触发了非周期信道状态信息报告但所调度的物理上行共享信道不 传输承载上行共享信道（ UL-SCH )的传输块的上行调度授权信令所调度的物 理上行共享信道的优先级高于触发了非周期信道状态信息报告但所调度的物 理上行共享信道传输承载上行共享信道的传输块的上行调度授权信令所调度 的物理上行共享信道的优先级。 其中， 对用户设备， 一个子帧上， 最多有一 个上行调度授权信令触发非周期 CSI报告且所调度的 PUSCH 不传输承载 UL-SCH的传输块。
例如， 触发了非周期 CSI报告但所调度的 PUSCH不传输承载 UL-SCH 的传输块的上行调度授权信令所调度的 PUSCH的优先级最高。 例如， 首次传输的物理上行共享信道的优先级高于重传的物理上行共享 信道的优先级。
例如， 自适应重传的 PUSCH的优先级高于非自适应重传的 PUSCH。 例如， 基于竟争的随机接入过程中的随机接入响应调度的 PUSCH不用 于承载 UCI。
为清楚描述如何根据上述因素确定不同物理上行共享信道的优先级， 本 方法中， 根据上述因素将物理上行共享信道分为多个等级 （level ) , 等级越 高的物理上行共享信道优先级越高。 当有多个物理上行共享信道的等级相同 时， 根据预定义的规则确定此多个物理上行共享信道的优先级。
优选地， 当多个物理上行共享信道的优先级等级相同时， 选择此多个物 理上行共享信道所在分量载波的优先级最高的一个物理上行共享信道。
需要注意的是， 等级概念的弓 )入是为了清楚描述如何确定物理上行共享 信道的优先级， 任何根据上述因素确定物理上行共享信道的优先级的方法， 不论是否使用等级或类似概念， 都属于本发明所保护的范围。

此预定义的规则包括， 优先选择触发了非周期 CSI报告的上行调度授权 信令所调度的 PUSCH,如果没有所述触发了非周期 CSI报告的上行调度授权 信令所调度的 PUSCH, 根据多个 PUSCH所在分量载波的优先级排序选择优 先级最高的一个 PUSCH。
( 2 ) 如果没有动态调度的 PUSCH, 根据预定义的规则选择所述多个 PUSCH中一个 PUSCH承载 UCI。
此预定义的规则包括， 根据所述多个 PUSCH所在分量载波的优先级排 序选择优先级最高的一个 PUSCH。
实现方式二
对用户设备，一个子帧上，可以有多个上行调度授权信令触发非周期 CSI 报告。
