Description

一种信息的传输方法及装置
技术领域
本发明涉及无线通信领域, 尤其涉及一种信息的传输方法及装 置。
背景技术
在 LTE (Long Term Evolution, 长期演进)通信系统中, 存在 CA (Carrier Aggregation, 载波聚合)技术, 即两个或者两个以上 的成员载波可以聚合在一起用于数据传输以支持更大的带宽, 这些 聚合的成员载波可以同时为一个用户服务, 进行数据的收发。
CA系统中, 由于为用户设备服务的不同小区的信号到达用户设 备的传播时延不同, 因此将为用户设备服务的多个小区按照其信号 到达用户设备的传播时延的不同划分成不同的 TAG( Timing Advance Group, 定时提前组)。
目前, LTE 系统中引入了双连接技术, 该双连接技术为基站之 间的载波聚合, 且基站之间为非理想回传连接, 不同基站下的小区 不属于同一个 TAG, 因此, 用户设备发往两个 eNB ( Evolved NodeB, 演进基站)的上行子帧会发生交叠。 又由于基站之间为非理想回传连 接, 不同基站的下行定时不要求一定是同步的, 即基站的下行定时 可能是异步的, 因此, 用户设备发往不同 TAG 的小区的子帧的交叠 区域大于一个符号的范围。 并且, 由于基站间的非理想回传连接的 原因, 一个基站的下行定时和该基站对用户设备在某个子帧的调度 情况, 对于另一个基站来说是未知的。 用户设备发送的上行子帧的 不同符号由于与属于另一个 TAG 的不同上行子帧的部分交叠而可能 进行了不同的功率压缩, 造成一个子帧内的不同符号的发射功率不 同。 基站由于无法获知该可能具有不同功率设置的符号的集合, 对 于基站接收和解调该子帧的 PUSCH ( Physical Uplink Shared Channel, 物理上行共享信道) 造成困难。 另外, 由于基站不知道不 同符号的功率设置情况, 对于高阶调制的解调, 基站需要知道调制 符号的幅度信息, 因此影响解调性能。 现有的双连接技术中, 基站釆用盲检测用户设备发送的一个子 帧的每个符号的功率, 判断用户设备对于不同的符号集合的发射功 率的设置的不同。 例如, 基站接收一个子帧的 1 4个符号, 检测这些 符号的接收功率, 其中符号 1 - 7 的接收功率水平相近, 均为 P 1 , 符 号 8 - 1 4 的符号功率水平相近, 均为 P 2 , 则基站判断用户设备对于 符号 1 - 7和符号 8 - 1 4具有不同的功率设置, 并根据该判断结果对该 子帧进行解调。 但是, 基站釆用盲检测的方法复杂度较高。

用户设备, 可以是无线终端也可以是有线终端, 无线终端可以 是指向用户提供语音和 /或数据连通性的设备, 具有无线连接功能的 手持式设备、 或连接到无线调制解调器的其他处理设备。 无线终端 可以经无线接入网 (例如, RAN, radio access network ) 与一个或 多个核心网进行通信, 无线终端可以是移动终端, 如移动电话 (或 称为 "蜂窝" 电话) 和具有移动终端的计算机, 例如, 可以是便携 式、 袖珍式、 手持式、 计算机内置的或者车载的移动装置, 它们与 无线接入网交换语言和 /或数据。例如,个人通信业务( PCS, personal communication service ) 电话、 无绳电话、 会话发起协议 ( SIP ) 话机、 无线本地环路 ( WLL, wireless local loop ) 站、 个人数字 助理 ( PDA, personal digital assistant ) 等设备。 无线终端也可 以称为系统、 订户单元 ( subscriber unit )、 订户站 ( subscriber station ), 移动站 ( mobile station ), 移动台 ( mobile ), 远程站 ( remote station ) , 接入点 ( access point )、 远程终端 ( remote terminal )、 接入终端 ( access terminal )、 用 户 终端 ( user terminal ), 用户代理 ( user agent )、 用户设备 ( user device ) , 或用户装备 ( user equipment )。
在 LTE 通信系统中, 存在 CA (Carrier Aggregation, 载波聚 合)技术, 即两个或者两个以上的成员载波可以聚合在一起用于数据 传输以支持更大的带宽, 这些聚合的成员载波可以同时为一个用户 服务, 进行数据的收发。 现有 CA系统是同一个基站下的载波进行聚 合, 或者有理想回传的 eNodeB的小区之间的载波聚合, 比如主基站 MeNodeB和辅基站 SeNodeB之间通过光纤连接。 在理想回传部署下, eNodeB 之间或者同一个 eNodeB 的不同小区之间可以实现及时的信 息交互, 并且 CA系统中多个小区的下行发射定时是同步的。
CA系统中, 由于为用户设备服务的不同小区的信号到达用户设 备的传播时延不同, 因此将为用户设备服务的多个小区按照其信号 到达用户设备的传播时延的不同划分成不同的 TAG。
在同一个 TAG 下的小区, 用户设备根据共同的定时提前命令调 整其上行信道的定时。 在现有 CA系统中, 如果用户设备同时发射的 上行信道的小区属于多个 TAG, 那么属于不同 TAG 的小区的上行信 道的定时差不超过一个符号的长度。 如图 1 所示, 在 TAG1 的子帧 subframe i 的上行信道的最后一个符号 (颜色加深部分) 就很可能 和 TAG 2的子帧 subframe i + 1的上行信道的第一个符号有部分交叠, TAG1 的 subframe i 的上行信道的最后一个符号同时还和 TAG2 的 subframe i 的上行信道的最后一个符号部分重叠。
在现有 CA技术中, 当用户设备的上行发射功率超过用户设备允 许的最大发射功率时, 用户设备需要进行功率压缩, 以满足最大发 射功率限制。 对于不同 TAG 下的重叠符号, 当用户设备的发射功率 超过其最大发射功率时, 用户设备进行如下的处理:
( 1 )如果重叠符号中有包含 SRS( Sounding Reference Symbol , 探测参考信号) 的符号, 该符号会被丟弃。
( 2 ) 当属于一个 TAG 的上行子帧发送 PUCCH ( Physical Downlink Shared Channel , 物理下行共享信道), 属于另一个 TAG 的上行子帧发送 PUSCH ( Phys ical Uplink Shared Channel , 物理 上行共享信道), 用户设备需要保证重叠的符号的不同的重叠部分的 发射功率不超过最大发射功率。
( 3 ) 当属于一个 TAG的上行子帧发送 PRACH ( Phys ical Random Access Channel, 物理随机接入信道), 属于另一个 TAG的上行子帧 发送 PUSCH/PUCCH, 用户设备需要调整 PUSCH/PUCCH 的功率以保证 重叠部分的发射功率不超过最大发射功率。
对于上述第二、 三点, 根据信道的优先级在功率压缩时, 用户 设备的发射功率需要优先保证 PRACH 的功率, 其次是 PUCCH, 最后 的 PUSCH。 也就是说, PUSCH的功率会最先被压缩。
针对上述用户设备对上行子帧的处理, eNodeB在接收到用户设 备的上行子帧后, eNodeB 对 PUSCH 信道的子帧中与属于其他 TAG 的子帧的重叠符号的功率进行检测, 并与该子帧中其他符号的功率 进行比较。 当该重叠符号的功率明显低于该子帧其他符号的功率时, 对该重叠符号的功率进行补偿, 再与该子帧的其他符号一起进行解 码。
在现有 CA技术中, 不同的小区的定时是同步的, 而且因为是理 想回传, 不同 TAG下用户设备的上行子帧的交叠情况和可能发生的 功率压缩情况对于 eNodeB来说也是可以预期的。
然而, 双连接技术中 (即为基站之间的载波聚合, 且基站之间 为非理想回传连接, 不同基站的下行定时不要求一定是同步的), 不 同基站下的小区不属于同一个 TAG, 因此, 用户设备发往两个 eNB 的上行子帧会发生交叠。 又由于基站之间为非理想回传连接, 不同 基站的下行定时不要求一定是同步的, 即基站的下行定时可能是异 步的, 因此, 用户设备发往不同 TAG 的小区的子帧的交叠区域大于 一个符号的范围。 并且, 由于基站间的非理想回传连接的原因, 一 个基站的下行定时和该基站对用户设备在某个子帧的调度情况, 对 于另一个基站来说是未知的。 用户设备发送的上行子帧的不同符号 集合由于与属于另一个 TAG 的不同的上行子帧的部分交叠而可能进 行了不同的功率压缩, 造成一个子帧内的不同符号的发射功率不同。 基站由于无法获知该可能具有不同功率设置的符号集合, 导致基站 接收和解调该子帧的 PUSCH 造成困难。 另外, 由于基站不知道不同 符号的功率设置情况, 对于高阶调制的解调, 基站需要知道调制符 号的幅度信息, 因此影响解调性能。
示例性的, 如图 2所示, TAG2的子帧 subframe i + 1 与 TAG1 的 子帧 subframe i 和 subframe i + 1 都发生交叠, 交叠区域分另1 J是 overla por t i onl 和 over lap portion 2。 为了满足用户设备的最 大发射功率限制, 用户设备在不同的交叠区域都必须满足不超过最 大发射功率。而由于交叠区域的不同, over lap port ion 1和 overlap portion 2 有可能进行了不同的功率设置。 基站由于无法获知可能 具有不同功率设置的符号集合 overlap portion 1 和 over lap portion 2, 导致基站接收和解调该子帧的 PUSCH造成困难。
现有的双连接技术中, 基站釆用盲检测用户设备发送的一个子 帧的不同符号的功率, 判断用户设备对于不同的符号集合的发射功 率的设置的不同。 但是, 基站釆用盲检测的方法复杂度较高。
本发明实施例提供一种信息的传输方法, 通过用户设备确定指 示子帧中的至少一个集合的发射功率指示信息, 并将承载有该发射 功率指示信息的信令发送至基站, 使得基站根据该发射功率指示信 息确定子帧中的至少一个集合, 而无需对子帧中的每个符号的功率 进行盲检才能确定用户设备对子帧中不同符号集合的发射功率的设 置, 减少了双连接技术中基站盲检测的复杂度。

本发明实施例提供一种信息的传输方法, 如图 1 1所示, 包括: S 1 0 用户设备确定第一子帧中的所有符号的发射功率指示信 息。
其中, 发射功率指示信息指示第一子帧中的至少一个集合, 集 合至少包括一个符号, 且一个集合中的所有符号的发射功率相同。
由于在 CA系统为双连接聚合的应用场景中,用户设备发送的上 行子帧的不同符号集合与属于另一个 TAG 的不同上行子帧的部分交 叠而可能进行了不同的功率压缩, 因此, 用户设备需要确定第一子 帧中的所有符号的发射功率指示信息, 该发射功率指示信息指示出 了第一子帧中的至少一个集合, 这里, 集合为子帧中的符号的集合。
具体的, 用户设备确定第一子帧中的所有符号的发射功率指示 信息, 即用户设备确定第一子帧中的至少一个集合, 本发明实施例 中, 第一子帧中的集合数量可以为一个, 也可以为两个, 还可以为 三个, 本发明实施例不做限定。
进一步地, 用户设备确定第一子帧中的至少一个集合, 需要用 户设备首先在该第一子帧中确定出第一符号, 其中, 第一符号与第 二子帧重叠, 且第一符号与第三子帧重叠; 或者, 第一符号的边界 与第二子帧的边界重叠, 且第一符号的边界与第三子帧的边界重叠。 另外, 第二子帧和第三子帧相邻并属于相同的定时提前组, 且与第 一子帧属于不同的定时提前组。
示例性的, 如图 1 2所示, TAG 1 的子帧 i 中第一符号与 TAG 2的 子帧 i重叠, 且 TAG 1 的子帧 i 中第一符号与 TAG 2 的子帧 i + 1 重叠, TAG 2的子顿 i与 TAG 2 的子顿 i + 1 ^目 ^ 。
需要说明的是, 用户设备确定第一子帧中的第一符号的方法, 可以釆用任何可行的方法, 本发明实施例不做限定。
示例性的, 用户设备根据第一子帧和第二子帧的定时差 (定时 差为第一子帧的边界与第二子帧的边界的差值, 该定时差小于等于 预设值) 釆用下述公式确定第一符号:
Figure imgf000026_0001
其中, 表示第一符号在第一子帧中的位置, 说明第一符号 在第一子帧中为第几个符号, 7¾为时间单位, 表示用户设备上报 第一子帧和第二子帧的定时差为 n 个 T s , 。,为一个符号的 T s 个 数。
用户设备在第一子帧中确定出第一符号后, 根据该第一符号确 定第一子帧中的集合。
具体的, 用户设备确定第一符号属于第一集合, 或者, 第一符 号以及与第一符号相邻的两个符号中的至少一个符号属于第一集 合, 第一子帧中在第一集合之前的符号属于第二集合, 第一子帧中 在第一集合之后的符号属于第三集合。
需要说明的是,由于第一符号在第一子帧中的具体位置不一定, 用户设备根据该第一符号确定第一子帧中的集合的数量也不一定。 若第一符号为第一子帧中的第一个符号或第一子帧中的最后一个符 号, 则用户设备确定第一子帧中的集合的数量为两个 (第一集合和 第三集合, 或者, 第一集合和第二集合), 或者, 若用户设备确定第 一集合中的符号的功率与第三集合 (或第二集合) 中的符号的功率 相同, 则用户设备将第一集合与第三集合 (或第二集合) 合并为第 四集合, 即用户设备确定第一子帧中的集合的数量为两个 (第三集 合和第四集合, 或, 第二集合和第四集合); 或者, 用户设备确定第 一子帧中的集合的数量为一个 (第一集合, 或者, 第一子帧中的所 有符号为一个集合 )。
进一步地, 用户设备根据第一子帧中的集合的划分, 对各个集 合的符号功率设置有多种情况:
( 1 )第一子帧中存在三个集合时, 第二集合和第三集合的符号 的功率可以有不同的设置, 第一集合的符号的功率设置不确定, 可 以与第二集合的符号的功率相同, 也可能与第三集合的符号的功率 相同; ( 2 )第一子帧中存在两个集合时, 第一集合和第二集合的符号 功率可以有不同的设置, 或者, 第一集合和第三集合的符号的功率 可能有不同的设置, 但是不论这两种情况中的哪一种, 第一集合的 符号的功率小于或者等于另一集合的符号的功率; 或者, 第一集合 与第三集合 (或第二集合) 的符号功率设置相同, 因此合并为第四 集合, 第四集合与第二集合 (或第三集合) 的符号功率可以有不同 的设置, 且第四集合的符号功率小于或者等于第二集合 (或第三集 合) 的功率;
( 3 )第一子帧中存在一个集合时, 第一集合中的所有符号的功 率相同, 或者, 第一子帧中的所有符号的功率相同;
其中, 每一个集合中的所有符号的发射功率相同。
需要说明的是, 本发明实施例中的第一子帧为当前定时提前组 中的任意一个子帧。 用户设备确定第一子帧中的所有符号的发射功 率指示信息可以为用户设备在第一子帧之前的子帧确定的, 也可以 为用户设备在第一子帧确定的, 本发明实施例不做限定。
S 1 02、用户设备将承载有发射功率指示信息的信令发送至基站。 在用户设备确定第一子帧中的所有符号的发射功率指示信息 后, 用户设备将承载有该发射功率指示信息的信令发送至基站, 这 样, 基站就可根据该发射功率指示信息确定第一子帧中的集合的划 分。
需要说明的是, 用户设备确定并发送的发射功率指示信息给基 站指示了用户设备在当前子帧或者未来子帧的符号的发射功率设置 情况, 是用户设备对于其当前子帧或者未来子帧的符号的发射功率 设置向基站的承诺。 例如, 用户设备在子帧 i ( ≥1 ) 确定发射功率 指示信息, 并将承载有该发射功率指示信息的信令发送至基站, 该 发射功率指示信息指示用户设备在子帧 i +k ( k > \ ) 的符号的发射功 率设置情况。 这样, 基站根据该发射功率指示信息, 确定子帧 i +k 的符号的集合的划分。 即使用户设备在子帧 i + k 确定的发射功率指 示信息与用户设备在子帧 i 确定的发射功率指示信息不同, 用户设 备仍然按照在子帧 i 确定的发射功率指示信息对子帧 i +k 的符号的 发射功率进行设置。
与现有技术中基站需要盲检用户设备发送的子帧的每个符号的 功率, 才能判断用户设备对子帧中不同的符号集合的发射功率的设 置相比较而言, 本发明实施例中用户设备将承载有发射功率指示信 息的信令发送至基站, 使得基站能够根据该发射功率指示信息, 直 接获知用户设备对子帧中不同的符号集合的发射功率设置, 减少了 基站盲检测的复杂度。
本发明实施例提供一种信息的传输方法, 用户设备确定第一子 帧中的所有符号的发射功率指示信息, 其中, 发射功率指示信息指 示第一子帧中的至少一个集合, 集合至少包括一个符号, 且一个集 合中的所有符号的发射功率相同, 然后, 将承载有发射功率指示信 息的信令发送至基站, 以使得基站根据发射功率指示信息确定第一 子帧中的至少一个集合。 通过该方案, 由于用户设备将指示第一子 帧中的至少一个集合的发射功率指示信息发送至基站, 使得基站能 够直接确定第一子帧中的至少一个集合, 而无需对第一子帧中的每 个符号的功率进行盲检才能确定用户设备对第一子帧中不同符号集 合的发射功率的设置, 减少了基站盲检测的复杂度。 实施例十
本发明实施例提供一种信息的传输方法, 如图 1 3所示, 包括:
S 2 0 基站接收用户设备发送的信令, 该信令用于承载用户设 备确定的第一子帧中的所有符号的发射功率指示信息。
其中, 发射功率指示信息指示第一子帧中的至少一个集合, 集 合至少包括一个符号, 且一个集合中的所有符号的发射功率相同。
现有技术中, 在 CA 系统为双连接聚合的应用场景中, 基站需要 盲检测用户设备发送的子帧的每个符号的功率, 才能判断用户设备 对子帧中不同的符号集合的发射功率的设置, 而基站釆用盲检测的 方法复杂度较高。 本发明实施例提供一种信息的传输方法, 能够减少基站盲检测 的复杂度。 基站直接接收用户设备发送的信令, 该信令用于承载用 户设备确定的第一子帧中的所有符号的发射功率指示信息, 且发射 功率指示信息指示第一子帧中的至少一个集合, 这里集合指的是子 帧中符号的集合。 这样, 基站即可直接获得第一子帧中集合的划分 情况。
进一步地,发射功率指示信息指示第一子帧中的至少一个集合, 第一子帧中的集合的数量为一个、 两个或三个。
需要说明的是, 本发明实施例中的第一子帧为用户设备的当前 定时提前组中的任意一个子帧, 本发明实施例不做限定。
S 2 02、 基站根据发射功率指示信息, 确定第一子帧中的至少一 个集合。
基站在接收到用户设备发送的发射功率指示信息后, 根据该发 射功率指示信息, 确定第一子帧中的至少一个集合, 即基站根据发 射功率指示信息确定第一子帧中的集合的划分情况, 第一子帧中的 集合的数量为一个、 两个或三个, 进而, 基站根据第一子帧中的集 合的划分情况对第一子帧进行解调。
本发明实施例提供一种信, I,的传输方法, 基站接收用户设备发 送的信令, 其中, 信令用于承载用户设备确定的第一子帧中的所有 符号的发射功率指示信息, 发射功率指示信息指示第一子帧中的至 少一个集合, 集合至少包括一个符号, 且一个集合中的所有符号的 发射功率相同, 然后, 根据发射功率指示信息, 确定第一子帧中的 至少一个集合。 通过该方案, 由于用户设备将指示第一子帧中的至 少一个集合的发射功率指示信息发送至基站, 使得基站能够直接确 定第一子帧中的至少一个集合, 而无需对第一子帧中的每个符号的 功率进行盲检才能确定用户设备对第一子帧中不同符号集合的发射 功率的设置, 减少了基站盲检测的复杂度。 实施例十一 本发明实施例提供一种信息的传输方法, 如图 1 4所示, 包括:
S 30 用户设备确定第一子帧中的第一符号。
由于在 CA系统为双连接聚合的应用场景中,用户设备发送的上 行子帧的不同符号集合与属于另一个 TAG 的上行子帧的部分交叠而 可能进行了不同的功率压缩, 并且, 用户设备发往不同 TAG 的小区 的子帧的交叠区域大于一个符号的范围, 因此, 用户设备首先确定 第一子帧中的第一符号。
具体的, 用户设备根据不同子帧的交叠情况确定第一子帧中的 第一符号位。 其中, 第一符号与第二子帧重叠, 且第一符号与第三 子帧重叠; 或者, 第一符号的边界与第二子帧的边界重叠, 且第一 符号的边界与第三子帧的边界重叠; 第二子帧和第三子帧相邻并属 于相同的定时提前组, 且与第一子帧属于不同的定时提前组。
示例性的, 如图 1 5 所示, TAG 1 的子帧 i 中第一符号的边界与 TAG 2 的子帧 i 的边界重叠, 且 TAG 1 的子帧 i 中第一符号的边界与 TAG 2的子帧 i + 1 的边界重叠。
具体的, 一个子帧中包含有 1 4个符号, 用户设备确定的第一符 号位可以为第一子帧中的任意一个符号, 即第一符号可以为第一子 帧中的第 i个符号 ( 1≤ ≤14 )。
需要说明的是, 用户设备确定第一子帧中的第一符号的方法, 可以釆用任何可行的方法, 本发明实施例不做限定。
示例性的, 用户设备根据第一子帧和第二子帧的定时差 (定时 差为第一子帧的边界与第二子帧的边界的差值, 该定时差小于等于 预设值) 釆用下述公式确定第一符号:
nTs
p 其中, ^„ ^表示第一符号在第一子帧中的位置, 说明第一符号 在第一子帧中为第几个符号, 7¾为时间单位, 表示用户设备上报 第一子帧和第二子帧的定时差为 n 个 T s , 。,为一个符号的 T s 个 数。 S 302、 用户设备确定第一符号属于第一集合, 或者, 第一符号 以及与第一符号相邻的两个符号中的至少一个符号属于第一集合, 第一子帧中在第一集合之前的符号属于第二集合, 第一子帧中在第 一集合之后的符号属于第三集合。
用户设备在第一子帧中确定出第一符号后, 根据该第一符号确 定第一子帧中的集合。 用户设备确定第一符号属于第一集合, 或者, 第一符号以及与第一符号相邻的两个符号中的至少一个符号属于第 一集合, 第一子帧中在第一集合之前的符号属于第二集合, 第一子 帧中在第一集合之后的符号属于第三集合。
具体的, 一个子帧中包含有 14个符号, 若用户设备确定的第一 符号位为第一子帧中的第 1 个符号, 且第一集合中仅仅包括第 1 个 符号时, 则用户设备确定在第一子帧中从第 2个符号到第 14个符号 之间的符号属于第三集合; 若用户设备确定的第一符号位为第一子 帧中的最后一个符号, 且第一集合中仅仅包括最后一个符号时, 则 用户设备确定在第一子帧中从第 1个符号到第 1 3个符号之间的符号 属于第二集合; 若用户设备确定的第一符号位为第一子帧中的第 i 个符号 ( 2≤ ≤13 ) , 且第一集合中仅仅包括第 i个符号时, 则用户设 备确定在第一子帧中从第 1 个符号到第 i - 1 个符号之间的符号属于 第二集合,从第 i + 1个符号到第 1 4个符号之间的符号属于第三集合; 若用户设备确定在第一子帧中从第 1 个符号到第 i - 1 个符号之间的 符号属于第二集合, 从第 i + 1个符号到第 1 4个符号之间的符号属于 第三集合,且用户设备确定第一集合中的符号的功率与第三集合(或 第二集合) 中的符号的功率相同, 则用户设备将第一集合与第三集 合 (或第二集合) 合并为第四集合, 即用户设备确定在第一子帧中 从第 1 个符号到第 i - 1 个符号之间的符号属于第二集合, 从第 i 个 符号到第 14个符号之间的符号属于第四集合(或在第一子帧中从第 1 个符号到第 i 个符号之间的符号属于第四集合, 从第 i + 1 个符号 到第 14个符号之间的符号属于第三集合)。
对于第一集合中包括第一符号以及与第一符号相邻的两个符号 中的至少一个符号时, 用户设备确定第二集合和第三集合和 /或第四 集合的原理与第一集合仅仅包括第一符号时, 用户设备确定第二集 合和第三集合和 /或第四集合的原理完全相同, 这里不再赘述。
可以理解的是,由于第一符号在第一子帧中的具体位置不一定, 用户设备根据该第一符号确定第一子帧中的集合的数量也不一定。 若第一符号为第一子帧中的第一个符号或第一子帧中的最后一个符 号, 则用户设备确定第一子帧中的集合的数量为两个 (第一集合和 第三集合, 或者, 第一集合和第二集合), 或者, 若用户设备确定第 一集合中的符号的功率与第三集合 (或第二集合) 中的符号的功率 相同, 则用户设备将第一集合与第三集合 (或第二集合) 合并为第 四集合, 即用户设备确定第一子帧中的集合的数量为两个 (第三集 合和第四集合, 或, 第二集合和第四集合); 或者, 用户设备确定第 一子帧中的集合的数量为一个 (第一集合, 或者, 第一子帧中的所 有符号为一个集合 )。
进一步地, 用户设备根据第一子帧中的集合的划分, 对各个集 合的功率设置有多种情况:
( 1 )第一子帧中存在三个集合时, 第二集合和第三集合的符号 的功率可以有不同的设置, 第一集合的符号的功率设置不确定, 可 以与第二集合的符号的功率相同, 也可能与第三集合的符号的功率 相同;
( 2 )第一子帧中存在两个集合时, 第一集合和第二集合的符号 的功率可以有不同的设置, 或者, 第一集合和第三集合的符号的功 率可能有不同的设置, 但是不论这两种情况中的哪一种, 第一集合 的符号的功率小于或者等于另一集合的符号的功率; 或者, 第一集 合与第三集合 (或第二集合) 的符号功率设置相同, 因此合并为第 四集合, 第四集合与第二集合 (或第三集合) 的符号功率可以有不 同的设置, 且第四集合的符号功率小于或者等于第二集合 (或第三 集合) 的功率;
( 3 )第一子帧中存在一个集合时, 第一集合中的所有符号的功 率相同, 或者, 第一子帧中的所有符号的功率相同;
其中, 每一个集合中的所有符号的发射功率相同。
S 30 3、 用户设备将承载有指示第一子帧中的至少一个集合的发 射功率指示信息的信令发送至基站。
在用户设备确定第一子帧中的所有符号的发射功率指示信息 后, 用户设备将承载有该发射功率指示信息的信令发送至基站, 这 样, 基站就可根据该发射功率指示信息确定第一子帧中的集合的划 分。
其中, 该信令包括第一子帧中至少一个集合包含的符号。
示例性的, 若第一子帧中集合为第一集合、 第二集合和第三集 合, 则该信令包括第一集合的所有符号, 或者, 该信令包含第二集 合的所有符号和第三集合的所有符号, 或者, 该信令包含第一集合、 第二集合和第三集合的所有符号。
需要说明的是, 本发明实施例中的第一子帧为当前定时提前组 中的任意一个子帧。 用户设备确定第一子帧中的所有符号的发射功 率指示信息可以为用户设备在当前定时提前组中第一子帧之前的子 帧确定的, 也可以为用户设备在第一子帧确定的, 本发明实施例不 做限定。
S 304、 基站根据发射功率指示信息, 确定第一子帧中的至少一 个集合。
相对应的, 用户设备将承载有指示第一子帧中的至少一个集合 的发射功率指示信息的信令发送至基站, 基站即可接收到用户设备 发送的发射功率指示信息。
具体的, 基站在接收到用户设备发送的发射功率指示信息后, 根据该发射功率指示信息, 确定第一子帧中的至少一个集合, 即确 定第一子帧中的集合的划分情况, 进而, 基站根据第一子帧中的集 合的划分情况对第一子帧进行解调。
需要说明的是, 用户设备确定并发送的发射功率指示信息给基 站指示了用户设备在当前子帧或者未来子帧的符号的发射功率设置 情况, 是用户设备对于其当前子帧或者未来子帧的符号的发射功率 设置向基站的承诺。 例如, 用户设备在子帧 i ( ≥1 ) 确定发射功率 指示信息, 并将承载有该发射功率指示信息的信令发送至基站, 且 该发射功率指示信息指示用户设备在子帧 i+k ( k>\ ) 的符号的发射 功率设置情况。 基站根据该发射功率指示信息, 确定子帧 i + k 的符 号的集合的划分。 这样, 即使用户设备在子帧 i + k 确定的发射功率 指示信息与用户设备在子帧 i 确定的发射功率指示信息不同, 用户 设备仍然按照在子帧 i 确定的发射功率指示信息对子帧 i + k 的符号 的发射功率进行设置。
与现有技术中基站需要盲检用户设备发送的子帧的每个符号的 功率, 才能判断用户设备对子帧中不同的符号集合的发射功率的设 置相比较而言, 避免了基站通过盲检测接收符号的功率来判断集合 的划分, 减少了基站盲检测的复杂度。
虽然, 现有技术可以通过盲检测检测每个符号的发射功率的情 况, 而本发明方法釆用用户设备的信令通知基站的方式, 可能会带 来额外的信令开销。 但是, 现有技术中基站在釆用盲检测的情况下, 还存在基站无法判断是否可以使用 DMRS ( Demodulation reference signal, 解调参考信号) 的 OCC (Orthogonal Covering Code, 正交 覆盖码)的问题。
当 PUSCH—个子帧的两个参考信号 DMRS的发射功率不同时,不 能够对 DMRS使用 0CC以获得和其他的用户设备的 DMRS的正交。 0CC 是由基站配置给用户设备的, 而用户设备的上行发射功率是动态改 变的, 特别依赖于和什么优先级的信道重叠, 第一符号的功率可能 和前面的符号相同, 也可能和后面的符号相同。 基站无法通过动态 的盲检测的结果判断用户设备对于不同符号集合的功率设置情况, 从而决定 DMRS的 0CC的配置。 因此, 釆用盲检测并不可行, 需要用 户设备上报给基站必要的信息, 即本发明方法中用户设备发送信令 至基站是有必要的。
本发明实施例提供一种信息的传输方法, 用户设备确定第一子 帧中的所有符号的发射功率指示信息, 其中, 发射功率指示信息指 示第一子帧中的至少一个集合, 集合至少包括一个符号, 且一个集 合中的所有符号的发射功率相同, 然后, 将承载有发射功率指示信 息的信令发送至基站, 以使得基站根据发射功率指示信息确定第一 子帧中的至少一个集合。 通过该方案, 由于用户设备将指示第一子 帧中的至少一个集合的发射功率指示信息发送至基站, 使得基站能 够直接确定第一子帧中的至少一个集合, 而无需对第一子帧中的每 个符号的功率进行盲检才能确定用户设备对第一子帧中不同符号集 合的发射功率的设置, 减少了基站盲检测的复杂度。 实施例十二
本发明实施例提供一种信息的传输方法, 如图 1 6所示, 包括: S 4 01、用户设备确定第一子帧中的解调参考信号 DMRS的配置指 示信息。
上行子帧中的 DMRS符号的位置由基站配置, 如图 1 7所示, 一 个子帧有两个时隙, 每个时隙有 7 个符号, 每个时隙中的一个符号 发送 DMRS。 基站为用户设备配置 DMRS 的正交序列, 保证该用户设 备的 DMRS 与其他用户设备的 DMRS 的正交性。 基站可以通过为用户 设备配置 0CC, 放到两个 DMRS 符号上作为 DMRS 的序列, 保证与其 他用户设备的 DMRS的序列的正交性。
现有的双连接技术中, 基站无法获知接收到的子帧中可能具有 不同功率设置的符号集合, 因此基站釆用盲检测用户设备发送的一 个子帧的不同符号的功率, 判断用户设备对于不同的符号集合的发 射功率的设置的不同。 在基站釆用盲检测的情况下, 还存在基站无 法判断是否可以使用 DMRS的 0CC的问题。
0CC 是由基站配置给用户设备的, 而用户设备的上行发射功率 是动态改变的, 特别依赖于和什么优先级的信道重叠, 第一集合的 功率可能和第二集合相同, 也可能和第三集合相同。 基站无法通过 动态的盲检测的结果判断用户设备对于不同符号集合的功率设置情 况, 从而决定 DMRS的 0CC的配置。
此外, 虽然,基站通过为用户设备配置 0CC ,将其放到两个 DMRS 符号上作为 DMR S 的序列, 能够保证与其他用户设备的 DMRS 的序列 的正交性, 但是, 这样要求一个子帧的两个 DMRS符号的功率相等, 才能保证正交性。 当 PUS CH—个子帧的两个参考信号 DMRS的发射功 率不同时,不能够对 DMR S使用 0CC以获得和其他的用户设备的 DMRS 的正交。 例如, 基站为用户设备 1 的 DMRS 配置 0CC 1为 (1, 1 ) , 基站 为用户设备 2 的 DMRS 配置 0CC 2为 (1, - 1 ) , ( 1 , 1 ) 和(1,_ 1 )是正交 的。 如果用户设备 1 的两个 DMRS符号的发射功率相同, 则两个 DMRS 符号的 0CC 乘上幅度后变成(a, a)。 同理, 如果用户设备 2 的两个 DMRS 符号的发射功率相同, 则两个 DMRS 符号的 0CC 乘上幅度后变 成(b,_b)。 则 (a, a )和(b,- b)依然是正交的。 但是, 如果用户设备 的一个子帧的两个 DMRS符号的功率不相等, 例如用户设备 1和用户 设备 2 的两个 DMRS 符号的 0CC 乘上幅度后分别变成(a, c)和(b, -d) , 则 (a, c)和(b, _d)是不正交的。 此时, 基站不能通过为用户 设备的 DMRS 配置 0CC来保证正交性。
为了解决基站无法获知是否可以使用 DMRS的 0CC的问题,或者, 解决基站无法获知子帧中的两个 DMR S 的符号是否处于相同集合的 问题, 或者, 解决基站无法获知子帧中的两个 DMRS的符号的发射功 率是否相同的问题, 用户设备首先确定第一子帧中的解调参考信号 DMR S的配置指示信息。
其中,配置指示信息指示第一子帧中的解调参考信号 DMRS是否 可以配置正交覆盖码 0CC ; 或者, 指示第一子帧中的两个解调参考 信号 DMRS符号的功率是否相等; 或者, 指示第一子帧中的两个解调 参考信号 DMRS符号是否属于同一集合, 其中, 集合至少包括一个符 号。
S 4 02、 用户设备将承载有配置指示信息的信令发送至基站。 用户设备在确定第一子帧中的解调参考信号 DMR S 的配置指示 信息后, 将承载有该配置指示信息的信令发送至基站, 以使得基站 根据接收到的配置指示信息获取相应的信息, 进而, 进行相应的操 作。
本发明实施例提供一种信息的传输方法, 用户设备确定第一子 帧中的解调参考信号 DMRS的配置指示信息, 其中, 配置指示信息指 示第一子帧中的解调参考信号 DMR S是否可以配置正交覆盖码 0CC ; 或者, 指示第一子帧中的两个解调参考信号 DMRS符号的功率是否相 等; 或者, 指示第一子帧中的两个解调参考信号 DMRS符号是否属于 同一集合, 集合至少包括一个符号, 然后, 用户设备将承载有配置 指示信息的信令发送至基站, 以使得基站根据配置指示信息确定第 一子帧中的解调参考信号 DMRS是否可以配置正交覆盖码 0CC ;或者, 基站根据配置指示信息确定第一子帧中的两个解调参考信号 DMRS 符号的功率是否相等; 或者, 基站根据配置指示信息确定第一子帧 中的两个解调参考信号 DMR S符号是否属于同一集合。 通过该方案, 由于用户设备将第一子帧中的解调参考信号 DMRS 的配置指示信息 发送至基站, 使得基站能够直接从该配置指示信息中获取到 DMRS的 相关信息, 进而完成相应的后续处理。 实施例十三
本发明实施例提供一种信息的传输方法, 如图 1 8所示, 包括: S 5 0 基站接收用户设备发送的信令, 其中, 信令用于承载用 户设备确定的第一子帧中的解调参考信号 DMRS的配置指示信息。
现有的双连接技术中, 基站无法获知接收到的子帧中可能具有 不同功率设置的符号集合, 因此基站釆用盲检测用户设备发送的一 个子帧的不同符号的功率, 判断用户设备对于不同的符号集合的发 射功率的设置的不同。 在基站釆用盲检测的情况下, 还存在基站无 法判断是否可以使用 DMRS的 0CC的问题。 同时, 虽然, 基站通过为 用户设备配置 0CC , 将其放到两个 DMRS 符号上作为 DMRS 的序列, 能够保证与其他用户设备的 DMRS的序列的正交性, 但是, 这样要求 一个子帧的两个 DMRS符号的功率相等, 才能保证正交性。 若 PUSCH 一个子帧的两个参考信号 DMRS的发射功率不同, 基站不能通过为用 户设备的 DMRS 配置 0CC来保证正交性。
本发明实施例提供一种信息的传输方法, 能够使得基站直接确 定子帧中 DMRS 的相关信息, 进而对 DMRS进行后续处理。 基站首先 接收用户设备发送的信令, 该信令用于承载用户设备确定的第一子 帧中的解调参考信号 DMRS的配置指示信息。
其中,配置指示信息指示第一子帧中的解调参考信号 DMRS是否 可以配置正交覆盖码 0CC ; 或者, 指示第一子帧中的两个解调参考 信号 DMRS符号的功率是否相等; 或者, 第一子帧中的两个解调参考 信号 DMRS符号是否属于同一集合, 集合至少包括一个符号。
S 5 02、 基站根据配置指示信息, 对第一子帧中的两个解调参考 信号 DMRS做相应处理。
基站在接收到用户设备发送承载有用户设备确定的第一子帧中 的解调参考信号 DMRS的配置指示信息的信令后, 根据配置指示信息 确定第一子帧中的解调参考信号 DMRS 是否可以配置正交覆盖码 0CC ; 或者, 确定第一子帧中的两个解调参考信号 DMRS 符号的功率 是否相等; 或者, 确定第一子帧中的两个解调参考信号 DMRS符号是 否属于同一集合。
本发明实施例提供一种信, I,的传输方法, 基站接收用户设备发 送的信令, 其中, 信令用于承载用户设备确定的第一子帧中的解调 参考信号 DMRS的配置指示信息, 配置指示信息指示第一子帧中的解 调参考信号 DMR S是否可以配置正交覆盖码 0CC ; 或者, 配置指示信 息指示第一子帧中的两个解调参考信号 DMRS符号的功率是否相等; 或者, 配置指示信息指示第一子帧中的两个解调参考信号 DMR S符号 是否属于同一集合, 集合至少包括一个符号; 然后, 基站根据配置 指示信息, 确定第一子帧中的解调参考信号 DMRS是否可以配置正交 覆盖码 0CC ; 或者, 确定第一子帧中的两个解调参考信号 DMRS符号 的功率是否相等; 或者, 确定第一子帧中的两个解调参考信号 DMRS 符号是否属于同一集合。 通过该方案, 由于用户设备将第一子帧中 的解调参考信号 DMRS的配置指示信息发送至基站, 使得基站能够直 接从该配置指示信息中获取到 DMRS的相关信息, 进而完成相应的后 续处理。 实施例十四
本发明实施例提供一种信息的传输方法, 如图 19所示, 包括: S601、用户设备确定第一子帧中的解调参考信号 DMRS的配置指 示信息。
上行子帧中的 DMRS符号的位置由基站配置, 如图 9所示, 一个 子帧有两个时隙, 每个时隙有 7 个符号, 每个时隙中的一个符号发 送 DMRS。 基站为用户设备配置 DMRS 的正交序列, 保证该用户设备 的 DMRS 与其他用户设备的 DMRS 的正交性。 基站可以通过为用户设 备酉己置 OCC (Orthogonal Covering Code, 正交覆盖码), 放 J两个 DMRS符号上作为 DMRS的序列, 保证与其他用户设备的 DMRS的序列 的正交生。
现有的双连接技术中, 基站无法获知接收到的子帧中可能具有 不同功率设置的符号集合, 因此基站釆用盲检测用户设备发送的一 个子帧的不同符号的功率, 判断用户设备对于不同的符号集合的发 射功率的设置的不同。 在基站釆用盲检测的情况下, 还存在基站无 法判断是否可以使用 DMRS的 0CC的问题。
0CC是由基站配置给用户设备的, 而用户设备的上行发射功率 是动态改变的, 特别依赖于和什么优先级的信道重叠, 第一集合的 功率可能和第二集合相同, 也可能和第三集合相同。 基站无法通过 动态的盲检测的结果判断用户设备对于不同符号集合的功率设置情 况, 从而决定 DMRS的 0CC的配置。
此外, 虽然,基站通过为用户设备配置 0CC ,将其放到两个 DMRS 符号上作为 DMRS 的序列, 能够保证与其他用户设备的 DMRS 的序列 的正交性, 但是, 这样要求一个子帧的两个 DMRS符号的功率相等, 才能保证正交性。 当 PUSCH—个子帧的两个参考信号 DMRS的发射功 率不同时,不能够对 DMR S使用 0CC以获得和其他的用户设备的 DMRS 的正交。 例如, 基站为用户设备 1 的 DMRS 配置 0CC 1为 (1, 1 ) , 基站 为用户设备 2 的 DMRS 配置 0CC 2为 (1, - 1 ) , ( 1 , 1 ) 和(1,_ 1 )是正交 的。 如果用户设备 1 的两个 DMRS符号的发射功率相同, 则两个 DMRS 符号的 0CC 乘上幅度后变成(a, a)。 同理, 如果用户设备 2 的两个 DMRS 符号的发射功率相同, 则两个 DMRS 符号的 0CC 乘上幅度后变 成(b,_b)。 则 (a, a )和(b,- b)依然是正交的。 但是, 如果用户设备 的一个子帧的两个 DMRS符号的功率不相等, 例如用户设备 1和用户 设备 2 的两个 DMRS 符号的 0CC 乘上幅度后分别变成(a, c)和(b, -d) , 则 (a, c)和(b, _d)是不正交的。 此时, 基站不能通过为用户 设备的 DMRS 配置 0CC来保证正交性。
为了解决基站无法获知是否可以使用 DMRS的 0CC的问题,或者, 解决基站无法获知子帧中的两个 DMR S 的符号是否处于相同集合的 问题, 或者, 解决基站无法获知子帧中的两个 DMRS的符号的发射功 率是否相同的问题, 用户设备首先确定第一子帧中的解调参考信号 DMR S的配置指示信息。
其中,配置指示信息指示第一子帧中的解调参考信号 DMRS是否 可以配置正交覆盖码 0CC ; 或者, 指示第一子帧中的两个解调参考 信号 DMRS符号的功率是否相等; 或者, 指示第一子帧中的两个解调 参考信号 DMRS符号是否属于同一集合, 其中, 集合至少包括一个符 号。
S 6 02、 用户设备将承载有所述配置指示信息的信令发送至基站 用户设备在确定第一子帧中的解调参考信号 DMR S 的配置指示 信息后, 将承载有该配置指示信息的信令发送至基站, 以使得基站 根据接收到的配置指示信息获取相应的信息, 进而, 进行相应的操 作。
S 6 0 3、 基站根据所述指示信息, 对第一子帧中的两个解调参考 信号 DMRS做相应处理。
基站在接收到用户设备发送承载有用户设备确定的第一子帧中 的解调参考信号 DMRS的配置指示信息的信令后, 根据配置指示信息 确定第一子帧中的解调参考信号 DMRS 是否可以配置正交覆盖码 0CC ; 或者, 确定第一子帧中的两个解调参考信号 DMRS 符号的功率 是否相等; 或者, 确定第一子帧中的两个解调参考信号 DMRS符号是 否属于同一集合。
本发明实施例提供一种信息的传输方法, 用户设备确定第一子 帧中的解调参考信号 DMRS的配置指示信息, 其中, 配置指示信息指 示第一子帧中的解调参考信号 DMR S是否可以配置正交覆盖码 0CC ; 或者, 指示第一子帧中的两个解调参考信号 DMRS符号的功率是否相 等; 或者, 指示第一子帧中的两个解调参考信号 DMRS符号是否属于 同一集合, 集合至少包括一个符号, 然后, 用户设备将承载有配置 指示信息的信令发送至基站, 以使得基站根据配置指示信息确定第 一子帧中的解调参考信号 DMRS是否可以配置正交覆盖码 0CC ;或者, 基站根据配置指示信息确定第一子帧中的两个解调参考信号 DMRS 符号的功率是否相等; 或者, 基站根据配置指示信息确定第一子帧 中的两个解调参考信号 DMR S符号是否属于同一集合。 通过该方案, 由于用户设备将第一子帧中的解调参考信号 DMRS 的配置指示信息 发送至基站, 使得基站能够直接从该配置指示信息中获取到 DMRS的 相关信息, 进而完成相应的后续处理。 实施例十五
本发明实施例提供一种信息的传输方法, 如图 2 0所示, 包括: S 7 01、 用户设备确定第一子帧和第二子帧的定时差信息。
其中, 第一子帧和第二子帧属于不同的定时提前组, 且第一子 帧和第二子帧的定时差小于预设值。
示例性的, 如图 4所示, TAG 1 的子帧 i 的边界与 TAG 2的子帧 i 的边界不对齐, 存在定时差 T 0。
由于在 CA系统为双连接聚合的应用场景中,用户设备发送的上 行子帧的不同符号集合与属于另一个 TAG 的不同上行子帧的部分交 叠而可能进行了不同的功率压缩, 因此, 用户设备需要确定第一子 帧和第二子帧的定时差信息, 其中, 定时差为第一子帧的边界与第 二子帧的边界的差值, 且该定时差小于等于预设值, 第一子帧和第 二子帧属于不同的定时提前组。
具体的, 用户设备确定第一子帧和第二子帧的定时差信息后, 用户设备通过利用该定时差信息确定第一子帧中的集合的数量, 即 确定第一子帧中集合的划分, 这里集合为第一子帧中符号的集合。 本发明实施例中, 第一子帧中的集合数量可以为一个, 也可以为两 个, 还可以为三个, 本发明实施例不做限定。
进一步地, 用户设备确定第一子帧中的至少一个, 需要用户设 备首先在该第一子帧中确定出第一符号, 其中, 第一符号与第二子 帧重叠, 且第一符号与第三子帧重叠; 或者, 第一符号的边界与第 二子帧的边界重叠, 且第一符号的边界与第三子帧的边界重叠。 另 外, 第二子帧和第三子帧相邻并属于相同的定时提前组, 且与第一 子帧属于不同的定时提前组。
示例性的, 如图 4 所示, TAG 1 的子帧 i 中第一符号与 TAG 2 的 子帧 i重叠, 且 TAG 1 的子帧 i 中第一符号与 TAG 2 的子帧 i + 1 重叠, TAG 2的子顿 i与 TAG 2 的子顿 i + 1 ^目 ^ 。
需要说明的是, 用户设备利用定时差信息确定第一子帧中的第 一符号的方法, 可以釆用任何可行的方法, 本发明实施例不做限定。
用户设备在第一子帧中确定出第一符号后, 根据该第一符号确 定第一子帧中的集合。
具体的, 用户设备确定第一符号属于第一集合, 或者, 第一符 号以及与第一符号相邻的两个符号中的至少一个符号属于第一集 合, 第一子帧中在第一集合之前的符号属于第二集合, 第一子帧中 在第一集合之后的符号属于第三集合。
需要说明的是,由于第一符号在第一子帧中的具体位置不一定, 用户设备根据该第一符号确定第一子帧中的集合的数量也不一定。 若第一符号为第一子帧中的第一个符号或第一子帧中的最后一个符 号, 则用户设备确定第一子帧中的集合的数量为两个 (第一集合和 第三集合, 或者, 第一集合和第二集合), 或者, 若用户设备确定第 一集合中的符号的功率与第三集合 (或第二集合) 中的符号的功率 相同, 则用户设备将第一集合与第三集合 (或第二集合) 合并为第 四集合, 即用户设备确定第一子帧中的集合的数量为两个 (第二集 合和第四集合, 或, 第三集合和第四集合); 或者, 用户设备确定第 一子帧中的集合的数量为一个 (第一集合, 或者, 第一子帧中的所 有符号为一个集合 )。
进一步地, 用户设备根据第一子帧中的集合的划分, 对各个集 合的符号功率设置有多种情况:
( 1 )第一子帧中存在三个集合时, 第二集合和第三集合的符号 的功率可以有不同的设置, 第一集合的符号的功率设置不确定, 可 以与第二集合的符号的功率相同, 也可能与第三集合的符号的功率 相同;
( 2 )第一子帧中存在两个集合时, 第一集合和第二集合的符号 功率可以有不同的设置, 或者, 第一集合和第三集合的符号的功率 可能有不同的设置, 但是不论这两种情况中的哪一种, 第一集合的 符号的功率小于或者等于另一集合的符号的功率; 或者, 第一集合 与第三集合 (或第二集合) 的符号功率设置相同, 因此合并为第四 集合, 第四集合与第二集合 (或第三集合) 的符号功率可以有不同 的设置, 且第四集合的符号功率小于或者等于第二集合 (或第三集 合) 的功率;
( 3 )第一子帧中存在一个集合时, 第一集合中的所有符号的功 率相同, 或者, 第一子帧中的所有符号的功率相同;
其中, 每一个集合中的所有符号的发射功率相同。
需要说明的是, 本发明实施例中的第一子帧为当前定时提前组 中的任意一个子帧, 第二子帧为其他定时提前组中的子帧, 且第一 子帧和第二子帧的定时差小于预设值。 用户设备确定第一子帧和第 二子帧的定时差信息可以为用户设备在当前定时提前组中第一子帧 之前的子帧确定的, 也可以为用户设备在第一子帧确定的, 本发明 实施例不做限定。
S 7 02、 用户设备将承载有定时差信息的信令发送至基站。
在用户设备确定第一子帧和第二子帧的定时差信息后, 用户设 备将承载有该定时差信息的信令发送至基站, 这样, 基站就可根据 该定时差信息确定第一子帧中的集合的划分。
需要说明的是, 用户设备确定并发送的定时差信息给基站指示 了用户设备根据该定时差信息在当前子帧或者未来子帧的符号的发 射功率设置情况, 是用户设备对于其当前子帧或者未来子帧的符号 的发射功率设置向基站的承诺。 例如, 用户设备在子帧 i ( ≥l ) 确 定定时差信息, 并将承载有该定时差信息的信令发送至基站, 且该 定时差信息指示用户设备在子帧 i +k ( k > \ ) 根据该定时差信息得到 子帧 i +k 的符号的发射功率设置情况。 基站根据该定时差信息, 确 定在子帧 i +k的符号的集合的划分。 这样, 即使用户设备在子帧 i +k 确定的定时差信息与用户设备在子帧 i 确定的定时差信息不同, 用 户设备仍然按照在子帧 i 指示给基站的定时差信息对子帧 i +k 中的 符号的发射功率进行设置。
与现有技术中基站需要盲检用户设备发送的子帧的每个符号的 功率, 才能判断用户设备对子帧中不同的符号集合的发射功率的设 置相比较而言, 本发明实施例中用户设备将承载有定时差信息的信 令发送至基站, 减少了基站盲检测的复杂度。
本发明实施例提供一种信息的传输方法, 用户设备确定第一子 帧和第二子帧的定时差信息, 其中, 第一子帧和第二子帧属于不同 的定时提前组, 且第一子帧和第二子帧的定时差小于预设值, 然后, 将承载有定时差信息的信令发送至基站, 以使得基站根据定时差信 息确定第一子帧中的至少一个集合。 通过该方案, 由于用户设备将 第一子帧和第二子帧的定时差信息发送至基站, 使得基站能够直接 确定第一子帧中的至少一个集合, 而无需对第一子帧中的每个符号 的功率进行盲检才能确定用户设备对第一子帧中不同符号集合的发 射功率的设置, 减少了基站盲检测的复杂度。 实施例十六
本发明实施例提供一种信息的传输方法, 如图 2 1所示, 包括: S 8 0 基站接收用户设备发送的信令, 该信令用于承载用户设 备确定的第一子帧和第二子帧的定时差信息。
其中, 定时差为第一子帧的边界与第二子帧的边界的差值, 且 该定时差小于等于预设值, 一子帧和第二子帧属于不同的定时提前 组。
现有技术中, 在 CA 系统为双连接聚合的应用场景中, 基站需要 盲检用户设备发送的子帧的每个符号的功率, 才能判断用户设备对 子帧中不同的符号集合的发射功率的设置, 而基站釆用盲检测的方 法复杂度较高。
本发明实施例提供一种信息的传输方法, 能够减少基站盲检测 的复杂度。 基站直接接收用户设备发送的信令, 该信令用于承载用 户设备确定的第一子帧和第二子帧的定时差信息。 这样, 基站即可 直接获得第一子帧中集合的划分情况。
S 8 02、 基站根据定时差信息, 确定第一子帧中的第一符号, 进 而, 确定第一子帧中的至少一个集合。
基站在接收到用户设备发送的定时差示信息后, 根据定时差信 息, 确定第一子帧中的第一符号, 然后, 确定第一子帧中的至少一 个集合, 即确定第一子帧中的集合的划分情况, 进而, 基站根据第 一子帧中的集合的划分情况对第一子帧进行解调。
本发明实施例提供一种信, I,的传输方法, 基站接收用户设备发 送的信令, 其中, 信令用于承载用户设备确定的第一子帧和第二子 帧的定时差信息, 定时差为第一子帧的边界与第二子帧的边界的差 值, 且该定时差小于等于预设值, 一子帧和第二子帧属于不同的定 时提前组, 然后, 根据定时差信息, 确定第一子帧中的第一符号, 进而确定第一子帧中的至少一个集合。 通过该方案, 由于用户设备 将第一子帧和第二子帧的定时差信息发送至基站, 使得基站能够直 接确定第一子帧中的至少一个集合, 而无需对第一子帧中的每个符 号的功率进行盲检才能确定用户设备对第一子帧中不同符号集合的 发射功率的设置, 减少了基站盲检测的复杂度。 实施例十七
本发明实施例提供一种信息的传输方法, 如图 22所示, 包括: S 9 01、 用户设备确定第一子帧和第二子帧的定时差信息。
由于在 CA系统为双连接聚合的应用场景中,用户设备发送的上 行子帧的不同符号集合与属于另一个 TAG 的上行子帧的部分交叠而 可能进行了不同的功率压缩, 并且, 用户设备发往不同 TAG 的小区 的子帧的交叠区域大于一个符号的范围, 即不同 TAG 的小区的子帧 的边界存在一定差值, 因此, 用户设备首先确定第一子帧和第二子 帧的定时差信息。
其中, 第一子帧和第二子帧属于不同的定时提前组, 且第一子 帧和第二子帧的定时差小于预设值。
用户设备在确定第一子帧和第二子帧的定时差信息后, 根据该 定时差信息确定第一子帧中的第一符号。
具体的, 用户设备确定的第一子帧中的第一符号与第二子帧重 叠, 且第一符号与第三子帧重叠; 或者, 第一符号的边界与第二子 帧的边界重叠, 且第一符号的边界与第三子帧的边界重叠; 第二子 帧和第三子帧相邻并属于相同的定时提前组, 且与第一子帧属于不 同的定时提前组。
示例性的,如图 7所示, TAG 1的子帧 i中第一符号的边界与 TAG 2 的子帧 i 的边界重叠, 且 TAG 1 的子帧 i 中第一符号的边界与 TAG 2 的子帧 i + 1 的边界重叠。
具体的, 一个子帧中包含有 1 4个符号, 用户设备确定的第一符 号位可以为第一子帧中的任意一个符号, 即第一符号可以为第一子 帧中的第 i个符号 ( 1≤ ≤14 )。 需要说明的是, 用户设备确定第一子帧中的第一符号的方法, 可以釆用任何可行的方法, 本发明实施例不做限定。
示例性的, 用户设备根据第一子帧和第二子帧的定时差 (定时 差为第一子帧的边界与第二子帧的边界的差值, 该定时差小于等于 预设值) 釆用下述公式确定第一符号:
nTs
p 其中, ^^表示第一符号在第一子帧中的位置, 说明第一符号 在第一子帧中为第几个符号, 7¾为时间单位, 表示用户设备上报 第一子帧和第二子帧的定时差为 n 个 T s , 。,为一个符号的 T s 个 数。
需要说明的是, 在本实施例中, 用户设备釆用上述公式确定第 一符号时, 为了防止 " /Λ ^的计算结果在符号边界发生跳变, 以至 于用户设备计算的第一符号的位置 ^^发生变化, 而造成用户设备 根据第一符号位置确定的符号集合的划分发生变化, 与基站根据之 前用户设备上报给基站的定时差计算确定的符号集合的划分不一 致, 从而造成解调性能的损失。 为此规定, 当 " /Λ ^接近符号边界 时, 令用户设备和基站计算的 ^ , 以防止用户设备侧单方面发 生跳变, 而使新增加的一个重叠符号的功率设置发生变化, 且不能 被基站及时获知。 例如, 当 nTs
^ NT^s άΝ1 > 0.9时'J ,, Ps + 1 nTs
否则, ps 本发明实施例中用户设备利用定时差确定第一符号的方法与实 施例三中用户设备利用定时差确定第一符号的方法不同, 实施例三 中, 用户设备在确定第一子帧中的集合划分, 确定第一集合时, 已 经处理了上述问题, 因此用户设备可直接按照公式即可确定第一符 号。 在本实施例中, 用户设备只是将定时差信息发送至基站, 需要 规定用户设备和基站根据该定时差, 按照相同的规则处理跳变符号 问题, 以保证用户设备和基站侧行为一致。
用户设备在第一子帧中确定出第一符号后, 根据该第一符号确 定第一子帧中的集合。 用户设备确定第一符号属于第一集合, 或者, 第一符号以及与第一符号相邻的两个符号中的至少一个符号属于第 一集合, 第一子帧中在第一集合之前的符号属于第二集合, 第一子 帧中在第一集合之后的符号属于第三集合。
具体的, 一个子帧中包含有 14个符号, 若用户设备确定的第一 符号位为第一子帧中的第 1 个符号, 且第一集合中仅仅包括第 1 个 符号时, 则用户设备确定在第一子帧中从第 2个符号到第 14个符号 之间的符号属于第三集合; 若用户设备确定的第一符号位为第一子 帧中的最后一个符号, 且第一集合中仅仅包括最后一个符号时, 则 用户设备确定在第一子帧中从第 1个符号到第 1 3个符号之间的符号 属于第二集合; 若用户设备确定的第一符号位为第一子帧中的第 i 个符号 ( 2≤ ≤13 ) , 且第一集合中仅仅包括第 i个符号时, 则用户设 备确定在第一子帧中从第 1 个符号到第 i - 1 个符号之间的符号属于 第二集合,从第 i + 1个符号到第 1 4个符号之间的符号属于第三集合; 若用户设备确定在第一子帧中从第 1 个符号到第 i - 1 个符号之间的 符号属于第二集合, 从第 i + 1个符号到第 1 4个符号之间的符号属于 第三集合,且用户设备确定第一集合中的符号的功率与第三集合(或 第二集合) 中的符号的功率相同, 则用户设备将第一集合与第三集 合 (或第二集合) 合并为第四集合, 即用户设备确定在第一子帧中 从第 1 个符号到第 i - 1 个符号之间的符号属于第二集合, 从第 i 个 符号到第 14个符号之间的符号属于第四集合(或在第一子帧中从第 1 个符号到第 i 个符号之间的符号属于第四集合, 从第 i + 1 个符号 到第 14个符号之间的符号属于第三集合)。
对于第一集合中包括第一符号以及与第一符号相邻的两个符号 中的至少一个符号时, 用户设备确定第二集合和第三集合和 /或第四 集合的原理与第一集合仅仅包括第一符号时, 用户设备确定第二集 合和第三集合和 /或第四集合的原理完全相同, 这里不再赘述。
可以理解的是,由于第一符号在第一子帧中的具体位置不一定, 用户设备根据该第一符号确定第一子帧中的集合的数量也不一定。 若第一符号为第一子帧中的第一个符号或第一子帧中的最后一个符 号, 则用户设备确定第一子帧中的集合的数量为两个 (第一集合和 第三集合, 或者, 第一集合和第二集合), 或者, 若用户设备确定第 一集合中的符号的功率与第三集合 (或第二集合) 中的符号的功率 相同, 则用户设备将第一集合与第三集合 (或第二集合) 合并为第 四集合, 即用户设备确定第一子帧中的集合的数量为两个 (第二集 合和第四集合, 或, 第三集合和第四集合); 或者, 用户设备确定第 一子帧中的集合的数量为一个 (第一集合, 或者, 第一子帧中的所 有符号为一个集合 )。
进一步地, 用户设备根据第一子帧中的集合的划分, 对各个集 合的功率设置有多种情况:
( 1 )第一子帧中存在三个集合时, 第二集合和第三集合的符号 的功率可以有不同的设置, 第一集合的符号的功率设置不确定, 可 以与第二集合的符号的功率相同, 也可能与第三集合的符号的功率 相同;
( 2 )第一子帧中存在两个集合时, 第一集合和第二集合的符号 的功率可以有不同的设置, 或者, 第一集合和第三集合的符号的功 率可能有不同的设置, 但是不论这两种情况中的哪一种, 第一集合 的符号的功率小于或者等于另一集合的符号的功率; 或者, 第一集 合与第三集合 (或第二集合) 的符号功率设置相同, 因此合并为第 四集合, 第四集合与第二集合 (或第三集合) 的符号功率可以有不 同的设置, 且第四集合的符号功率小于或者等于第二集合 (或第三 集合) 的功率;
( 3 )第一子帧中存在一个集合时, 第一集合中的所有符号的功 率相同, 或者, 第一子帧中的所有符号的功率相同;
其中, 每一个集合中的所有符号的发射功率相同。 S 9 02、 用户设备将承载有定时差信息的信令发送至基站。
在用户设备确定第一子帧和第二子帧的定时差信息后, 用户设 备将承载有该定时差信息的信令发送至基站, 这样, 基站就可根据 该定时差信息确定第一子帧中的集合的划分。
需要说明的是, 本发明实施例中的第一子帧为当前定时提前组 中的任意一个子帧, 第二子帧为其他定时提前组中的子帧, 且第一 子帧和第二子帧的定时差小于预设值。 用户设备确定第一子帧和第 二子帧的定时差信息可以为用户设备在当前定时提前组中第一子帧 之前的子帧确定的, 也可以为用户设备在第一子帧确定的, 本发明 实施例不做限定。
S 9 0 3、 基站根据定时差信息, 确定第一子帧中的第一符号, 进 而, 确定第一子帧中的至少一个集合。
相对应的, 用户设备将承载有定时差信息的信令发送至基站, 基站即可接收到用户设备发送的定时差信息。
具体的, 基站在接收到用户设备发送的定时差信息后, 根据该 定时差信息, 确定第一子帧中的第一符号, 然后, 确定第一子帧中 的至少一个集合, 即确定第一子帧中的集合的划分情况, 进而, 基 站根据第一子帧中的集合的划分情况对第一子帧进行解调。
需要说明的是, 用户设备确定并发送的定时差信息给基站指示 了用户设备根据该定时差信息在当前子帧或者未来子帧的符号的发 射功率设置情况, 是用户设备对于其当前子帧或者未来子帧的符号 的发射功率设置向基站的承诺。 例如, 用户设备在子帧 i ( ≥l ) 确 定定时差信息, 并将承载有该定时差信息的信令发送至基站, 且该 定时差信息指示用户设备在子帧 i +k ( k > \ ) 根据该定时差信息得到 子帧 i +k 的符号的发射功率设置情况。 基站根据该定时差信息, 确 定在子帧 i +k的符号的集合的划分。 这样, 即使用户设备在子帧 i +k 确定的定时差信息与用户设备在子帧 i 确定的定时差信息不同, 用 户设备仍然按照在子帧 i 指示给基站的定时差信息对子帧 i +k 中的 符号的发射功率进行设置。 与现有技术中基站需要盲检用户设备发送的子帧的每个符号的 功率, 才能判断用户设备对子帧中不同的符号集合的发射功率的设 置相比较而言, 避免了基站通过盲检测接收符号的功率来判断集合 的划分, 减少了基站盲检测的复杂度。
虽然, 现有技术可以通过盲检测检测每个符号的发射功率的情 况, 而本发明方法釆用用户设备的信令通知基站的方式, 可能会带 来额外的信令开销。 但是, 现有技术中基站在釆用盲检测的情况下, 还存在基站无法判断是否可以使用 DMRS ( Demodulation reference signal, 解调参考信号) 的 OCC (Orthogonal Covering Code, 正交 覆盖码)的问题。
当 PUSCH—个子帧的两个参考信号 DMRS的发射功率不同时,不 能够对 DMRS使用 0CC 以获得和其他的用户设备的 DMRS的正交。 0CC 是由基站配置给用户设备的, 而用户设备的上行发射功率是动态改 变的, 特别依赖于和什么优先级的信道重叠, 第一符号的功率可能 和前面的符号相同, 也可能和后面的符号相同。 基站无法通过动态 的盲检测的结果判断用户设备对于不同符号集合的功率设置情况, 从而决定 DMRS的 0CC的半静态配置。 因此, 釆用盲检测并不可行, 需要用户设备上报给基站必要的信息, 即本发明方法中用户设备发 送信令至基站是有必要的。
本发明实施例提供一种信息的传输方法, 用户设备确定第一子 帧和第二子帧的定时差信息, 其中, 第一子帧和第二子帧属于不同 的定时提前组, 且第一子帧和第二子帧的定时差小于预设值, 然后, 将承载有定时差信息的信令发送至基站, 以使得基站根据定时差信 息确定第一子帧中的至少一个集合。 通过该方案, 由于用户设备将 第一子帧和第二子帧的定时差信息发送至基站, 使得基站能够直接 确定第一子帧中的至少一个集合, 而无需对第一子帧中的每个符号 的功率进行盲检才能确定用户设备对第一子帧中不同符号集合的发 射功率的设置, 减少了基站盲检测的复杂度。
