具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚地描述,显然,所描述的实施例是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员所获得的所有其他实施例,都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象,而不用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换,以便本申请的实施例能够以除了在这里图示或描述 的那些以外的顺序实施,且“第一”、“第二”所区别的对象通常为一类,并不限定对象的个数,例如第一对象可以是一个,也可以是多个。此外,说明书以及权利要求中“和/或”表示所连接对象的至少其中之一,字符“/”一般表示前后关联对象是一种“或”的关系。
值得指出的是,本申请实施例所描述的技术不限于长期演进型(Long Term Evolution,LTE)/LTE的演进(LTE-Advanced,LTE-A)系统,还可用于其他无线通信系统,诸如码分多址(Code Division Multiple Access,CDMA)、时分多址(Time Division Multiple Access,TDMA)、频分多址(Frequency Division Multiple Access,FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access,OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access,SC-FDMA)和其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用,所描述的技术既可用于以上提及的系统和无线电技术,也可用于其他系统和无线电技术。然而,以下描述出于示例目的描述了新空口(New Radio,NR)系统,并且在以下大部分描述中使用NR术语,这些技术也可应用于NR系统应用以外的应用,如第6代(6th Generation,6G)通信系统。
图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括终端11和网络侧设备12。其中,终端11也可以称作终端设备或者用户终端(User Equipment,UE),终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant,PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer,UMPC)、移动上网装置(Mobile Internet Device,MID)、可穿戴式设备(Wearable Device)或车载设备(VUE)、行人终端(PUE)等终端侧设备,可穿戴式设备包括:手环、耳机、眼镜等。需要说明的是,在本申请实施例并不限定终端11的具体类型。网络侧设备12可以是基站或核心网,其中,基站可被称为节点B、演进节点B、接入点、 基收发机站(Base Transceiver Station,BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set,BSS)、扩展服务集(Extended Service Set,ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、无线局域网(Wireless Local Area Network,WLAN)接入点、无线保真(Wireless Fidelity,WiFi)节点、发送接收点(Transmitting Receiving Point,TRP)或所述领域中其他某个合适的术语,只要达到相同的技术效果,所述基站不限于特定技术词汇,需要说明的是,在本申请实施例中仅以NR系统中的基站为例,但是并不限定基站的具体类型。
下面结合附图,通过具体的实施例及其应用场景对本申请实施例提供的技术方案进行详细地说明。
如图2所示,为本申请一示例性实施例提供的上行传输的方法200的流程示意图,该方法200可由终端执行,例如,可由安装于所述终端中的硬件和/或软件执行。其中,所述方法200可以包括如下步骤。
S210,根据第一信息确定第一持续时间。
其中,所述第一持续时间是用于所述终端在一个或多个上行传输时,需保持功率和/或相位连续性的时间。本实施例中,所述第一信息可以包括以下(1)-(7)中至少一项。
(1)网络侧设备指示的时间单元数。
其中,所述时间单元可以为时隙(slot)、子时隙(sub-slot)、符号(symbol)子帧(subframe)、无线帧(frame)等。
示例性的,假设所述第一持续时间仅基于(1)确定,那么,所述第一持续时间可以等于所述网络侧设备所指示的时间单元数,如所述网络侧设备指示的时间单位数为L个时间单元,如2个slot,则所述第一持续时间为2个slot。
需要注意,后续实施例中提及的“时间单元”均可以为时隙、子时隙、符号、子帧、无线帧等,后续不再赘述。
(2)网络侧设备指示的所述第一上行传输的重复传输次数。
其中,假设网络侧设备指示的所述第一上行传输的重复传输次数为N,且所述第一持续时间仅基于(2)确定,那么,所述第一持续时间可以为N次第一上行传输的重复传输对应的时间单元数。
(3)所述多个第一上行传输中的至少一个占用的连续/准连续的时间单元数。
其中,所述连续/准连续满足以下(3a)-(3e)至少之一的要求。
(3a)时域资源上的间隔(gap)时间不大于第三阈值。
(3b)时域资源上的间隔时间不大于预定符号数阈值。
(3c)时域资源上的间隔的数目不大于第四阈值。
(3d)时域资源上的间隔的数目不大于终端上报的第一持续时间的最长时间。
(3e)时域资源上不存在间隔,也就是,在不存在间隔的情况下,可认为连续。
前述(3a)-(3e)中,所述间隔可以位于所述时域资源上的中间位置或其他位置。所述时域资源可以理解为一个或多个第一上行传输对应的时域资源,例如,在所述时域资源为一个第一上行传输对应的时域资源的情况下,所述间隔可以位于所述一个第一上行传输的中间位置等;在所述时域资源为多个第一上行传输对应的时域资源的情况下,所述间隔可以位于相邻的两个第一上行传输的之间,也可以位于多个第一上行传输的任一个上行传输上,在此不做限制。
另外,前述的间隔的大小、第三阈值、符号数阈值、第四阈值可由网络侧配置或协议约定,在此不做限制。
一种实现方式中,如果所述第一持续时间是基于前述(3)所示的所述多个第一上行传输中的至少一个占用的连续/准连续的时间单元数确定,那么,后续在基于所述第一持续时间进行多个第一上行传输时,在所述连续/准连续 的时间单元数内进行的所述第一上行传输,可以使用相同位置的频域资源。
(4)配置的上/下行资源配置。
其中,所述上/下行资源配置可以由网络侧配置,例如,上行符号的配置(U)、下行符号(D)的配置或灵活符号(S)的配置、时分复用(Time Division Duplex,TDD)上下行slot配置等。
(5)指定信道的名义(nominal)传输的时域资源长度。
其中,所述时域资源长度可以但不限于大于1个slot,所述指定信道包括物理上行共享信道(Physical Uplink Shared Channel,PUSCH)和/或物理上行控制信道(Physical Uplink Control Channel,PUCCH)。
(6)指定时间资源。
其中,所述指定时间资源是为所述一个或多个第一上行传输确定解调参考信号(Demodulation Reference Signal,DMRS)所对应的时域资源。本实施例中,所述DMRS可以包括DMRS集束(bundling)、DMRS共享(sharing)、或其他DMRS优化传输方法中的DMRS等中的至少一种。另外,前述的“DMRS所对应的时域资源”可以理解为:用于确定DMRS传输的时域资源,不是所述DMRS实际占用的时域资源。
示例性的,假设所述第一持续时间仅基于(6)确定,那么,如果所述多个上行传输使用了DMRS bundling和/或DMRS sharing和/或在时域/频域资源进行了DMRS传输的优化,则终端认为其对应的时间资源为所述第一持续时间。
(7)终端能力信息。
其中,终端根据终端能力信息确定所述第一持续时间,也可以理解为:若所述网络侧设备不指示所述第一持续时间,则终端根据终端能力信息确定所述第一持续时间;若所述网络侧设备指示的第一持续时间超过了根据终端能力信息确定的第一持续时间,则终端根据终端能力信息确定的第一持续时间为所述第一持续时间。
示例性的,如果多个连续的第一上行传输的持续时间超过了终端(也可以理解为用户)的能力,那么,不要求终端保持这多个上行传输的功率和相位连续(Power and Phase continuity);或者,如果多个上行传输的功率和相位连续是由网络侧设备保证,即用户不期望被调度或者配置的多个连续的上行传输,其第一持续时间超过了用户的能力。
需要说明的是,所述第一持续时间可以基于(1)-(7)中的任一项确定,也可以基于(1)-(7)中的两项或多项确定,其中,在所述第一持续时间是基于(1)-(7)中的两项或多项确定的情况下,所述第一持续时间可以为以下(a)-(b)任意一个。
(a)至少两个第一时间长度值中的指定值。
其中,所述指定值为最大值或最小值,各所述第一时间长度值分别对应所述第一信息中的不同信息。例如,假设所述第一时间长度值有两个,分别为指定信道的名义传输的时域资源长度对应的第一长度值,以及指定时间资源对应的第二长度值,所述第一长度值大于所述第二长度值,在此情况下,如果所述指定值为最大值,那么所述第一持续时间为所述指定信道的名义传输的时域资源长度对应的第一长度值。
(b)至少两个第二时间之间的交集。
其中,各所述第二时间分别对应所述第一信息中的不同信息。本实施例中,根据所述第二时间对应所述第一信息中的不同信息,所述第二时间可以为时间长度,也可以为时间范围,在此不做限制。例如,在所述第二时间为时间范围的情况下,假设所述第二时间为两个,分别为(a1,a2)、(b1,b2),那么,所述第一持续时间可以为(a1,a2)与(b1,b2)之间的交集。
基于前述对第一持续时间的确定方式的描述,下面结合图2b-图2e对所述第一持续时间的确定进行进一步说明,其中,“U”表示上行时间单元、“D”表示下行时间单元、“S”表示灵活的时间单元。
如图2b所示,假设当前帧结构为“DDDSUDDSUU”,第二时间分别为前 述的(2)和(4)对应的时间,第一上行传输PUSCH在上行时隙(即图2b中的“U”)上进行重复传输,那么,所述第一持续时间可以为图2b中所示的第一个“U”对应的时间单元。
此外,所述网络侧设备还可以指示第一持续时间为传输的重复次数为单位,例如,将2次重复传输对应的时间长度作为第一持续时间,并且考虑帧结构。
如图2c所示,在“DDDSU”帧结构中,“S”slot的14个符号中的符号构成中包含2个上行符号,即最后两个符号,且终端在2+14个上行符号上进行传输,即图2c中所示的“S”slot的最后2个符号和“U”slot的14个符号。在此情况下,终端可以将连续的上行符号(2+14)个符号作为第一持续时间,该行为可以是网络侧设备指示的,或者预定义的。
或者,网络侧设备配置第一持续时间为2个slot,但实际第一持续时间不足两个slot,则第一持续时间为(2slots,连续符号数(number of consecutive symbols))中的最小值(min)。
又或者,如图2d所示,网络侧设备配置的第一持续时间为1个slot,每个slot中可以包含2个PUSCH的名义传输(即图2d中所示的“Nominal PUSCH repetition”),而其重复传输的时间长度为2+14个符号,则第一持续时间可以为(1slots,连续符号数)中的最大值(max)。
又或者,如图2e所示,网络侧设备配置的名义PUSCH重复传输的长度为1个slot(14个符号),由于下行传输的分割,在一个slot内的一个名义重复传输被分割成两个实际重复传输。可以预设或者网络指示第一持续时间为名义PUSCH重复传输的长度,或者大于等于该长度。然而实际的连续符号数为4或者7,则第一持续时间可以为(1slot/名义PUSCH的长度(nominal PUSCH length),number of consecutive symbols)中的最小值。或者,可以理解为名义重复传输的持续时间和连续符号数的交集。
需要注意的是:
(1)前述的PUSCH仅为一种可能上行传输,也就是说,上述图2b-图2e所示的第一持续时间的确定方式同样可以适用于PUCCH等其他上行传输。
(2)上述PUSCH为重复传输,也可为跨多个slot的PUSCH/PUCCH传输,所述多个slot可以是连续的或者非连续的。
(3)前述第一信息中包括的(1)、(2)、(3)和(5)中描述的方案也可以单独实施,例如对于FDD频段(paired spectrum),可以进行连续的上下行传输。
S220,基于所述第一持续时间,在第一服务小区上进行多个第一上行传输,所述多个第一上行传输满足预定要求。
其中,所述多个第一上行传输在所述第一持续时间满足所述预定要求,可以理解为:所述终端支持的所述多个第一上行传输的功率和相位连续,由此,使得网络侧设备可基于所述多个第一上行传输进行联合DMRS信道估计,提高上行传输性能。本实施例中,所述预定要求可由网络侧设备配置或协议约定,在此不做限制。
在前述给出的上行传输的方法中,所述第一上行传输可以包括PUCCH、PUSCH、物理随机接入信道(Physical Random Access Channel,PRACH)、探测参考信号(Sounding Reference Signal,SRS)中至少之一。
另外,所述第一上行传输可以包括至少一种信道和/或信号的连续传输。例如,所述第一上行传输可以只包括PUCCH,也可以同时包括PUCCH、PUSCH等,在此不做限制。
在本申请实施例中,终端根据第一信息确定第一持续时间,进而基于第一持续时间,在第一服务小区上进行多个第一上行传输,所述多个第一上行传输满足预定要求,由此,能够使得多个第一上行传输在第一持续时间内保持功率和相位连续,进而使得网络侧设备能够基于接收到的上行传输进行联合DMRS信道估计,有效提高上行传输性能。
如图3所示,为本申请一示例性实施例提供的上行传输的方法300的流 程示意图,该方法300可由终端执行,例如,可由安装于所述终端中的硬件和/或软件执行。其中,所述方法300可以包括如下步骤。
S310,根据第一信息确定第一持续时间。
其中,S310中的实现过程可参照前述方法200中的相关描述为避免重复,在此不再赘述。
S320,基于所述第一持续时间,在第一服务小区上进行多个第一上行传输,所述多个第一上行传输满足预定要求。
其中,S320的实现过程除了可参照前述方法200中的相关描述之外,作为一种可能的实现方式,所述终端在基于所述第一持续时间进行多个第一上行传输时,所述第一持续时间的起始时刻可以为所述第一上行传输的起始时刻;或者,所述第一持续时间的起始时刻为所述第一上行传输所在时间单元的起始时刻。
此外,在所述第一持续时间内传输的第一上行传输使用相同的第一传输参数,也即是,所述终端不根据接收到的发射功率控制(Transmit Power Control,TPC)命令改变发送功率、不根据网络指示的路径损耗(pathloss)参考信号(Reference Signal,RS)调整发送功率等。
其中,所述第一传输参数可以包括所述第一上行传输对应的发送功率、发送滤波器、预编码方式、天线映射方式、调制方式、发送波形中的至少一项。根据所述第一上行信号的不同,所述信号波形不同,例如,在所述第一上行传输为PUCCH format 0/1/3/4时,所述信号波形可以认为是离散傅里叶变换扩频正交频分复用(Discrete Fourier Transform-Spread Orthogonal Frequency Division Multiplexing,DFT-S-OFDM)波形,在所述第一上行传输为PUCCH format 2时,所述信号波形可以认为是循环前缀正交频分复用(Cyclic Prefix Orthogonal Frequency Division Multiplexing,CP-OFDM)波形;在所述第一上行传输为PRACH时,所述信号波形可以认为是DFT-S-OFDM波形。
示例性的,假设所述第一传输参数为发送功率,那么,在第一持续时间内,终端保持发送功率不变;即使终端测量的pathloss发生变化,终端也不会在第一持续时间内对发送功率进行调整;或者,即使终端收到TPC命令(command),终端也不会在第一持续时间内根据该TPC command调整发送功率;又或者,即使终端收到更新的pathloss参考RS的更新指示,终端也不会在第一持续时间内根据该更新的参考RS的测量值调整发送功率。
此外,如果需要对上行传输过程中的传输参数进行调整,可以以所述第一持续时间为时间单位,对所述第一上行传输对应的第二传输参数进行调整,所述第二传输参数可以包括所述第一上行传输的发送功率、发送滤波器、预编码方式、天线映射方式、调制方式中至少一项。
示例性的,终端可在完成一次第一持续时间内的第一上行传输后,根据更新的pathloss测量、TPC command、功控参考信号等,调整发送功率。
需要注意的是,所述第一传输参数和所述第二传输参数可以相同,也可以不同,在此不做限制。
又一种实现方式中,所述多个第一上行传输中的至少部分第一上行传输对应的第一持续时间的时间长度不同;或者,所述多个第一上行传输中分别对应的第一持续时间的时间长度相同。
进一步,在本实施例中,所述预定要求可以包括以下(1)-(7)至少一项。
(1)第二上行传输的信道根据第三上行传输的信道确定,所述第二上行传输为所述多个第一上行传输中任意一个,所述第三上行传输为所述多个第一上行传输中除所述第二上行传输之外的其他上行传输。
其中,前述(1)可以理解为:对于所述多个第一上行传输,其中一个上行传输的信道可以基于其他上行信道的信道确定,本实施例中,所述“确定”还可以理解为推测(infer)、预测等。
示例性的,假设所述多个第一上行信道包括第一上行信道c1、第二上行 信道c2、第二上行信道c3、第四上行信道c4,且所述第一上行信道c1、第二上行信道c2、第二上行信道c3对应的信道是已知的,那么,第四上行信道c4的信道可以基于所述第一上行信道c1、第二上行信道c2、第二上行信道c3中的至少一个对应的信道确定。
(2)所述多个第一上行传输使用相同的天线端口。
(3)所述多个第一上行传输之间的相位连续。
(4)所述多个第一上行传输分别对应的发送功率之间的差值小于第一阈值。
其中,所述第一阈值可以由网络侧设备配置或协议约定,如detaP1等。
(5)所述多个第一上行传输分别对应的发送滤波器相同。
(6)所述多个第一上行传输分别对应的预编码方式相同。
(7)所述多个第一上行传输分别对应的DMRS与数据(data)传输符号之间的差值小于第二阈值。
其中,所述数据传输符号可以理解为除所述DMRS之外的其他信息符号,如有用信息符号等。所述差值可以为功率差值,所述第二阈值可以由网络侧设备配置或协议约定,如0dB、3dB、4.77dB、detaP2等。在此情况下,所述多个第一上行传输满足预定要求可以为:所述多个第一上行传输分别对应的DMRS与有用符号之间的功率差值为0dB或者小于等于detaP2,本实施例在此不做限制。
可以理解,在本实施例中,所述预定要求可以包括前述(1)-(7)个中的一个或多个,在此不做限制。
需要注意的是,在所述终端在所述第一服务小区上被调度或配置有指定优先级的上行传输的情况下,和/或,在所述终端接收到指定指令的情况下,所述多个第一上行传输可以不要求满足所述预定要求。其中,指定优先级可以为高优先级等,所述指定指令可以包括动态时隙格式指示(dynamic Slot Format Indication,dynamic SFI)和/或上行冲突指示(Uplink Conflict Indication, UL CI)。
示例性的,如果所述终端在所述第一服务小区上被调度或配置有高优先级的PUSCH、传输高优先级码本的混合自动重传请求应答(Hybrid automatic repeat request acknowledgement,HARQ-ACK)的PUCCH,使得所述多个第一上行传输不满足所述第一持续时间,那么,也同样不要求所述多个第一上行传输满足所述预定要求,如功率与相位连续。
在此情况下,本实施例中给出上行传输的方法中,所述终端不期望在所述第一服务小区上被调度或被配置有指定优先级的上行传输,和/或,所述终端不期望接收到指定指令。
进一步,一种实现方式中,终端在基于第一持续时间,在第一服务小区上进行满足预定要求的多个第一上行传输时,可以选择不同的传输方式,下面结合不同的示例进行说明。
示例1,假设所述终端需要进行跳频传输,那么,可以将所述第一持续时间作为时域的粒度,再基于所述第一持续时间的长度,确定所述多个第一上行传输对应的频域传输位置;最后基于所述频域传输位置对多个所述第一上行传输进行跳频传输。
例如,如果网络指示终端进行跳频传输,则终端可以按第一持续时间的长度,确定频域传输位置。具体的,终端在4个第一持续时间、以及2个频域位置上进行传输,那么,终端跳频的方式如下图4a所示,在不同起始时刻的第一持续时间的频域传输位置可以不同。或者可以说,不同频域位置的第一持续时间可以不同。
示例2
假设所述终端需要依据DMRS进行上行传输时,那么,所述终端可以基于所述第一持续时间的长度,确定各所述第一上行传输的DMRS的传输图样(pattern),再基于所述DMRS的传输图样对多个所述第一上行传输进行传输。
例如,终端根据第一持续时间的slot数和/或symbol数,确定在该第一持续时间内的DMRS符号数,或者该第一持续时间内,每个slot/nominal(actual)PUSCH repetition中的DMRS的符号数。
示例性的,相关技术方案中,DMRS pattern是根据1个PUSCH传输符号数确定的,在支持第一持续时间内的多个第一上行(这里主要是PUSCH和/或PUCCH)传输,满足所述预定要求的情况下,可以支持多个传输的联合信道估计,则可以考虑降低DMRS的开销,以提升传输的码率。
本实施例中,如图4b所示,在所述第一持续时间不同的情况下,每个slot内包含的DMRS符号数可以不同。在一个第一持续时间只有1个slot的PUSCH传输中,DMRS为4个符号,在一个第一持续时间为2个slot的PUSCH传输中,每个slot中包含2个DMRS符号。
或者,网络侧设备配置了额外(additional)DMRS(DMRS的符号数较多)的PUSCH的传输,当连续传输的PUSCH的符号数大于阈值M,则no additional DMRS的方式进行PUSCH传输。也就是,终端根据上述第一持续时间的时长,隐式确定DMRS的pattern。
需要说明的是,终端根据第一持续时间确定各所述第一上行传输的DMRS的传输图样这一功能是否开启,可以由网络侧配置。
S330,发送能力指示信息。
其中,通过所述能力指示信息的发送,能够使得所述终端与所述网络侧设备的理解一致,确保上行传输性能。本实施例中,所述能力指示信息用于指示以下(1)-(3)至少之一。
(1)所述终端在第一服务小区上进行的多个第一上行传输是否满足预定要求。
(2)所述第一持续时间的最短时间。
(3)所述第一持续时间的最长时间。
一种实现方式中,所述能力指示信息所指示的第一持续时间的最长时间, 大于或等于网络侧设备指示的第一持续时间的最长时间。
本实施例中,能够进一步使得网络可以使用多个slot的DMRS做联合信道估计。
如图5a所示,为本申请一示例性实施例提供的上行传输的方法500的流程示意图,该方法500可由终端执行,例如,可由安装于所述终端中的硬件和/或软件执行。其中,所述方法500可以包括如下步骤。
S510,根据第一信息确定第一持续时间。
其中,S510的实现过程可以参阅前述方法200、300中的相关描述,为避免重复,在此不再赘述。
S520,基于所述第一持续时间,在第一服务小区上进行多个第一上行传输,所述多个第一上行传输满足预定要求。
其中,S520的实现过程除了可以参阅前述方法200、300中的相关描述之外,作为一种可能的实现方式,如果为所述终端配置有多个服务小区,且在所述第一持续时间内,所述终端在第二服务小区开始上行传输,则执行预定操作;那么也就是,终端在执行S520的同时,如果满足预定情况,则执行预定操作。可以理解,所述第二服务小区上的上行传输可以是所述网络侧设备通过高层信令(如无线资源控制(Radio Resource Control,RRC)信令等)、媒体访问控制控制单元(Medium Access Control-Control Element,MAC CE)、物理下行控制信道(Physical downlink control channel,PDCCH)等指示信息进行调度指示得到。
所述预定情况可以包括在所述第一持续时间内、所述终端在第二服务小区进行上行传输。所述上行传输可以包括但不限于PUSCH、PUCCH、SRS等。
所述预定操作包括以下(1)-(3)中的至少一项。
(1)丢弃在所述第二服务小区上进行的上行传输。
(2)保持在所述第二服务小区上进行的上行传输。相应的,所述终端在 第一服务小区上进行的多个第一上行传输不要求满足所述预定要求。
(3)丢弃在所述第一服务小区上进行的第一指定传输,所述第一指定传输是在发生重叠的时间单元上进行的上行传输,所述重叠的时间单元为所述第一服务小区上的第一上行传输与所述第二服务小区上的上行传输之间发生重叠的时间单元。
一种实现方式中,所述预定情况还可包括接收到预定指示,执行所述预定操作,其中,所述预定指示用于指示所述第二服务小区的上行传输的传输时间达到预定时间。所述预定时间可以由网络侧配置或协议约定。示例性的,所述终端可在接收到网络侧设备指示的在第二服务小区的上行传输的T时间之后执行前述预定操作。
本实施例中,除前述给出的实现方式之外,在所述第二服务小区对应的上行传输为预定优先级的传输的情况下,或者,在所述第二服务小区对应的上行传输为预定信道或信号的情况下,执行以下(1)或(2)任一项:
(1)保持在所述第二服务小区上进行的上行传输。
(2)丢弃在所述第一服务小区上进行的第一指定传输,所述第一指定传输是在发生重叠的时间单元上进行的上行传输,所述重叠的时间单元为所述第一服务小区上的第一上行传输与所述第二服务小区上的上行传输之间发生重叠的时间单元。
其中,所述预定优先级的传输包括:具有预定优先级的PUSCH和/或传输预定优先级码本对应的混合自动重传请求应答(Hybrid automatic repeat request acknowledgement,HARQ-ACK)的PUCCH。所述预定信道或信道包括物理随机接入信道(Physical Random Access Channel,PRACH)、携带消息3的物理上行共享信道(MSG3PUSCH)、携带消息A的物理上行共享信道(MSG-A PUSCH)、SRS中的至少之一。
相应的,在所述第二服务小区对应的上行传输不为预定优先级的传输的情况下,且所述第二服务小区对应的上行传输不为预定信道或信道的情况下, 丢弃在所述第二服务小区进行的上行传输。
需要注意的是,在前述实现方式中,在所述预定操作为所述保持在所述第二服务小区上进行的上行传输的情况下,基于所述第二服务小区上进行的上行传输的起始时刻,将所述第一持续时间划分为第一部分持续时间和第二部分持续时间,其中,所述第一部分持续时间和所述第二部分持续时间之间进行的所述第一上行传输不满足所述预定要求;或者,所述第一部分持续时间和所述第二部分持续时间上进行的所述第一上行传输继续满足所述预定要求。
相应的,在所述预定操作为所述保持在所述第二服务小区上进行的上行传输的情况下,基于所述第二服务小区上进行的上行传输的起始时刻,将所述第一持续时间划分为第一部分持续时间和第二部分持续时间,其中,所述第一部分持续时间上进行的所述第一上行传输满足所述预定要求,和/或,所述第二部分持续时间上进行的所述第一上行传输满足所述预定要求。
基于前述方法500的描述,下面结合图5b对前述实现方式进行进一步说明。
假设网络侧设备给终端配置了多个服务小区(serving cell),如第一服务小区、第二服务小区,其中,多个serving cell之间以载波聚合(Carrier Aggregation,CA)或者双连接(Dual Connectivity,DC)的方式进行配置。
其中,如果终端可能需要在多个serving cell上同时进行传输,例如图5b所示,终端在第一服务小区serving cell#1上的第一持续时间内进行多个第一上行传输的过程中,开始在第二服务小区serving cell#2上进行上行传输,在这种情况下,从终端开始在serving cell#2上进行上行传输的开始时刻,终端可能无法在第一持续时间内满足所述预定要求,因此,所述终端看可以执行前述方法500中所示的预定操作,如以下(1)-(3)中的至少一项。
(1)丢弃在所述第二服务小区上进行的上行传输。
(2)保持在所述第二服务小区上进行的上行传输。相应的,所述终端在 第一服务小区上进行的多个第一上行传输不要求满足所述预定要求。
(3)丢弃在所述第一服务小区上进行的第一指定传输,所述第一指定传输是在发生重叠的时间单元上进行的上行传输,所述重叠的时间单元为所述第一服务小区上的第一上行传输与所述第二服务小区上的上行传输之间发生重叠的时间单元。
一种实现方式中,所述serving cell#2的上行传输的slot/symbol n开始时刻之后的serving cell#1的第一部分上行传输,和slot/symbol n-1结束时刻之前的serving cell#1的第二部分上行传输之间,不要求满足所述预定要求,而所述第一部分上行传输的持续时间内,继续满足所述预定要求,和/或,所述第二部分上行传输的持续时间内,继续满足所述预定要求。
另一种实现方式中,如果serving cell#2的上行传输为高优先级的传输,或者为特定的信道/信号的情况下,执行预定操作中的(2)或者(3);否则执行(1);所述高优先级传输包括:高优先级的PUSCH、传输高优先级码本对应的HARQ-ACK的PUCCH。
又一种实现方式中,在终端收到网络指示在serving cell#2的上行传输的T时间之后执行所述预定操作。应注意,网络侧设备不会在serving cell#1的一个第一持续时间的传输前的T时间内,触发如上图5b所示的serving cell#2的上行传输。
如图6所示,为本申请一示例性实施例提供的上行传输的方法600的流程示意图,该方法600可由网络侧设备执行,例如,可由安装于所述网络侧设备中的硬件和/或软件执行。其中,所述方法600可以包括如下步骤。
