这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
图1是根据一示例性实施例示出的一种网络设备与终端的通信系统架构图。本公开提供的通信方法可以应用于图1所示的通信系统架构图中。如图1所示，网络侧设备可以基于图1所示的架构发送信令。
可以理解的是，图1所示的网络设备与终端的通信系统仅是进行示意性说明，无线通信系统中还可包括其它网络设备，例如还可以包括核心网设备、无线中继设备和无线回传设备等，在图1中未画出。本公开实施例对该无线通信系统中包括的网络设备数量和终端数量不做限定。
进一步可以理解的是，本公开实施例的无线通信系统，是一种提供无线通信功能的网络。无线通信系统可以采用不同的通信技术，例如码分多址(code division multiple access,CDMA)、宽带码分多址(wideband code division multiple access，WCDMA)、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 FDMA，SC-FDMA)、载波侦听多路访问/冲突避免(Carrier Sense Multiple Access with Collision Avoidance)。根据不同网络的容量、速率、时延等因素可以将网络分为2G(英文：generation)网络、3G网络、4G网络或者未来演进网络，如5G网络，5G网络也可称为是新无线网络(New Radio，NR)。为了方便描述，本公开有时会将无线通信网络简称为网络。
进一步的，本公开中涉及的网络设备也可以称为无线接入网设备。该无线接入网设备可以是：基站、演进型基站(evolved node B，基站)、家庭基站、无线保真(wireless fidelity，WIFI)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等，还可以为NR系统中的gNB，或者，还可以是构成基站的组件或一部分设备等。当为车联网(V2X)通信系统时，网络设备还可以是车载设备。应理解，本公开的实施例中，对网络设备所采用的具体技术和具体设备形态不做限定。
进一步的，本公开中涉及的终端，也可以称为终端设备、用户设备(User Equipment，UE)、移动台(Mobile Station，MS)、移动终端(Mobile Terminal，MT)等，是一种向用户提供语音和/或数据连通性的设备，例如，终端可以是具有无线连接功能的手持式设备、 车载设备等。目前，一些终端的举例为：智能手机(Mobile Phone)、口袋计算机(Pocket Personal Computer，PPC)、掌上电脑、个人数字助理(Personal Digital Assistant，PDA)、笔记本电脑、平板电脑、可穿戴设备、或者车载设备等。此外，当为车联网(V2X)通信系统时，终端设备还可以是车载设备。应理解，本公开实施例对终端所采用的具体技术和具体设备形态不做限定。
在通信技术的新一代版本中提出了联合信道估计，以增强物理上行共享信道PUSCH的覆盖范围。并且提出，使用PUSCH的A型重复来增强Msg3的覆盖范围。在引入Msg3A型重复后，使得跨时隙信道估计成为可能。
在Msg3的重复接收期间，在一定条件下，网络侧设备可以执行跨时隙信道估计。因此，针对于联合信道估计，网络侧设备以gNB为例，gNB和UE都需要一个时间窗口，UE在该时间窗口期间需要保持功率一致性和相位连续性，以配合gNB在该时间窗口执行联合信道估计。
其中，终端在gNB执行联合信道估计过程中需要保持功率一致性和相位连续性，保持功率一致性和相位连续性需要满足以下相关条件。
(1)调制等级不变
(2)在长度和频率位置方面的RB分配不变，并且在重复过程中不能启用时隙内和时隙间的跳频。
(3)发射功率水平不变
(4)终端的上行波束在射频范围(Frequency range，FR)2内不发生切换。
因此，若gNB需要执行联合信道估计，则需要指示终端在执行联合信道估计的时间窗口内保持上述相关条件保持不变。并且在一定条件下，跨时隙信道估计的信道估计结果会更加准确，有益于覆盖增强/覆盖恢复。
相关技术中，没有定义网络侧设备如何指示终端是否执行联合信道估计，以及执行联合信道估计需要的时间窗口。
本公开提出一种指示方法，用于网络侧设备指示终端在进行Msg3重复时，是否执行联合信道估计，以及执行联合信道估计需要的时间窗口。

在本公开再一些实施例中，还可以使用隐性的方式指示联合信道估计时间窗口长度的参数。例如，基于重复传输次数隐性确定联合信道估计时间窗口长度的参数。示例性的，联合信道估计时间窗口的长度为重复传输次数对应的时隙数/N。其中，N为正整数，例如，N为2。当然这不是对本公开的具体限定，仅仅是举例说明。
在本公开一些实施例中，第一消息用于指示联合信道估计的配置信息，其中，配置信息包括用于指示终端网络侧设备启用联合信道估计和联合信道估计时间窗口的长度的参数集或固定参数值。该实施例可以单独被实施，可以与本公开的任何一个其他的实施例一起被实施例。
在本公开其中一种实施例中，终端基于网络侧设备给出的RMSI指示，确定第一消息，其中，第一消息为一个固定值，终端基于该固定值确定网络侧启用或禁用联合信道估计，同时通过该固定值还可以进一步地确定联合信道估计窗口的长度。示例性的，RMSI中携带了该固定值，终端则确定网络侧启用了联合信道估计，进一步的，终端基于该固定值确定联合信道估计时间窗口的长度；RMSI中未携带该固定值，终端则确定网络侧未启用联合信道估计。示例性的，若RMSI中携带了该固定值，且该固定值为0或1，终端则确定网络侧禁用联合信道估计；若RMSI中携带了该固定值，且该值大于1，终端则确定网络侧启用联合信道估计，并且，进一步的，终端基于该固定值确定联合信道估计时间窗口的长度。

在本公开实施例中，将第一参数，确定为执行联合信道估计的时间窗口，针对重复次数的传输时间小于联合信道估计时间窗口的长度的情况，可以基于不同的策略，执行联合信道估计。可参见如下实施例。

在本公开再一些实施例中，还可以使用隐性的方式指示联合信道估计时间窗口长度的参数。例如，基于重复传输次数隐性确定联合信道估计时间窗口长度的参数。示例性的，联合信道估计时间窗口的长度为重复传输次数对应的时隙数/N。其中，N为正整数，例如， N为2。当然这不是对本公开的具体限定，仅仅是举例说明。
在本公开一些实施例中，第一消息用于指示联合信道估计的配置信息，其中，配置信息包括用于指示终端网络侧设备启用联合信道估计和联合信道估计时间窗口的长度的参数集或固定参数值。该实施例可以单独被实施，可以与本公开的任何一个其他的实施例一起被实施例。
在本公开其中一种实施例中，终端基于网络侧设备给出的RMSI指示，确定第一消息，其中，第一消息为一个固定值，终端基于该固定值确定网络侧启用或禁用联合信道估计，同时通过该固定值还可以进一步地确定联合信道估计窗口的长度。示例性的，RMSI中携带了该固定值，终端则确定网络侧启用了联合信道估计，进一步的，终端基于该固定值确定联合信道估计时间窗口的长度；RMSI中未携带该固定值，终端则确定网络侧未启用联合信道估计。示例性的，若RMSI中携带了该固定值，且该固定值为0或1，终端则确定网络侧禁用联合信道估计；若RMSI中携带了该固定值，且该值大于1，终端则确定网络侧启用联合信道估计，并且，进一步的，终端基于该固定值确定联合信道估计时间窗口的长度。
在本公开又一种实施例中，可以基于CRC为RA-RNTI加扰的DCI(例如DCI格式1_0)，确定指示联合信道估计的配置信息。其中一种方式中，在配置信息中，包括用于确定启用或禁用联合信道估计的固定值。若该固定值为0或1，则确定禁用联合信道估计。若该固定值为除1或0以外的其他取值，则确定启用联合信道估计，并基于该固定值确定联合信道估计时间窗口的长度。另一种方式中，在配置信息中，包括联合信道估计时间窗口的长度的参数集。其中该参数集，则由RMSI配置或协议规定，并进一步由CRC为RA-RNTI加扰的DCI指示其参数集索引。终端根据网络侧设备指示的参数集索引，确定参数集中的一个参数，并基于该参数确定是否启用联合信道估计，以及联合信道估计时间窗口长度。该参数集可以是一个表，该表格可以是新的列表，也可以是已有列表，例如调制与编码策略(Modulation and Coding Scheme，MCS)/TDRA表格。如果采用已有列表，则需要在已有列表中新增一个字段(例如新增一列)。示例性的，该参数集包括的参数为[0，2，4，8]，参数为0则表示禁止联合信道估计，参数为其他剩余参数中的任意一个参数，则确定启用联合信道估计，并将该参数确定为联合信道估计时间窗口的长度。当然参数0也可以为参数1，指示参数1时，确定不启用联合信道估计，在此不做具体限定。该实施方式可以是针对一组终端的配置。

在本公开再一种实施例中，可以基于CRC为TC-RNTI加扰的DCI(例如DCI格式0_0)，确定指示联合信道估计的配置信息。其中一种方式中，在配置信息中，包括用于确定启用或禁用联合信道估计的固定值。若该固定值为0或1，则确定禁用联合信道估计。若该固定值为除1或0以外的其他取值，则确定启用联合信道估计，并将该固定值确定为联合信道估计时间窗口的长度。另一种方式中，在配置信息中，包括联合信道估计时间窗口的长度的参数集。其中该参数集，则由RMSI配置或协议规定，并进一步由CRC为RA－RNTI加扰的DCI指示其参数集索引。终端根据网络侧设备指示的参数集索引，确定参数集中的一个参数，并基于该参数确定是否启用联合信道估计，以及联合信道估计时间窗口长度。该参数集可以是一个表，该表格可以是新的列表，也可以是已有列表，例如调制与编码策略(Modulation and Coding Scheme，MCS)/TDRA表格。如果采用已有列表，则需要在已有列表中新增一个字段(例如新增一列)。示例性的，该参数集包括的参数为[0，2，4，8]，参数为0则表示禁止联合信道估计，参数为其他剩余参数中的任意一个参数，则确定启用联合信道估计，并基于该参数确定联合信道估计时间窗口的长度。当然参数0也可以为参数1，指示参数1时，确定不启用联合信道估计，在此不做具体限定。
在本公开实施例中，如上述，网络侧设备确定联合信道估计时间窗口的长度的参数集或固定参数值。其中，该参数集中的每个参数或固定参数值，可以基于终端Msg3的重复传输次数确定。例如，确定参数集中的每个参数或固定参数值为，所有可选的重复传输次数的公因子。示例性的，可选的重复传输次数为4，8，则可以确定其参数集中的参数为2， 4。或者确定配置的固定参数值为4。当然这仅仅是举例说明，并不是对本公开的具体限定。
本公开实施例提供的指示方法，可以指示终端，网络侧设备启用联合信道估计，以及执行联合信道估计的时间窗口。解决了无法向终端指示启用联合信道估计，以及执行联合信道估计的时间窗口的问题。
在本公开实施例中，终端根据接收的配置信息，确定启用联合信道估计，并获取用于联合信道估计时间窗口的长度的参数。基于所获取的参数执行联合信道估计，可采用下述实施方式。
图16是根据一示例性实施例示出的一种指示方法的流程图。如图16所示，指示方法用于终端中，该实施例可以单独被实施，可以与本公开的任何一个其他的实施例一起被实施例。包括以下步骤。
在步骤S151中，基于配置参数，在参数集中确定第一参数，或将固定参数值确定为第一参数。
在步骤S152中，基于第一参数，确定执行联合信道估计时间窗口的长度。
在本公开实施例中，如上述确定配置参数，在参数集中确定第一参数，或将固定参数值确定为第一参数。并基于第一参数确定执行联合信道估计时间窗口的长度。本公开为便于描述，将在参数集中基于配置信息指示的参数称为第一参数。
在本公开一示例性实施例中，在配置参数中，获取用于确定联合信道估计时间窗口的长度的参数集，并将由基站指示的参数集中的一个参数，确定为执行联合信道估计时间窗口的长度。或者，在配置参数中，获取用于确定联合信道估计时间窗口的固定参数值，并将该参数值确定为执行联合信道估计时间窗口的长度。示例性的，用于确定联合信道估计时间窗口的长度的参数集包括多个参数，如，分别为2，4，8。指示联合信道估计时间窗口的长度的参数为4，则确定执行联合信道估计的持续时间为4。其中持续时间可以是时隙，即，联合信道估计时间窗口的长度为连续4个时隙。换言之，网络侧设备每隔4个时隙/重复执行一次联合信道估计。此处，持续时间也可以是其他调度时间单元，此处不做具体限定。
在本公开实施例中，将第一参数，确定为执行联合信道估计的时间窗口，针对重复次数的传输时间小于联合信道估计时间窗口的长度的情况，可以基于不同的策略，执行联合信道估计。可参见如下实施例。
在本公开实施例中，终端确定重复传输次数对应的传输时间。例如，重复传输的消息为Msg3，Msg3的重复传输的重复传输次数为2。确定的第一参数为4，则重复传输次数对应的传输时间小于第一参数，确定基于第一策略执行联合信道估计。
在本公开一些实施例中，基于第一策略执行联合信道估计包括，取消合信道估计。即，针对传输时间小于第一参数的情况，确定取消启用联合信道估计。
在本公开一些实施例中，基于第一策略执行联合信道估计还包括，基于预定义规则重新确定联合信道估计时间窗口的长度，并基于重新确定的时间窗口的长度，执行联合信道估计。
示例性的，可以基于预定义规则重新确定，重复传输次数的传输时间或传输时间的一半，为实际联合信道估计时间窗口的长度。还可以将重复传输次数的传输时间确定为执行联合信道估计时间窗口的长度。还可以将通信协议指示的固定值，确定为执行联合信道估计时间窗口的长度。还可以是根据配置参数，将网络侧设备指定的值，确定为执行联合信道估计时间窗口的长度。还可以将与指定的值相近且小于重复传输次数对应的传输时间的值，确定为执行联合信道估计的时间窗口。
在本公开一些实施例中，基于第一策略执行联合信道估计包括，基于重复传输次数的传输时间，重新确定联合信道估计时间窗口的长度。示例性的，将联合信道估计的持续时间指定为所有可选重复传输次数的公因子。基于该公因子确定执行联合信道估计的时间窗口。
在本公开实施例中，确定盲重复传输次数对应的传输时间，若基于传输时间执行联合信道估计之后的剩余传输时间，小于下一次执行联合信道估计时间窗口的长度，确定采用第二策略执行联合信道估计。
在本公开一些实施例中，基于第二策略执行联合信道估计包括，取消联合信道估计。即，针对传输时间执行联合信道估计之后的剩余传输时间，小于下一次执行联合信道估计时间窗口的长度的情况，确定取消启用联合信道估计。
在本公开一些实施例中，基于第二策略执行联合信道估计包括，取消传输时间与第一参数的商值的余数内时隙的联合信道估计。换言之，取消传输时间执行联合信道估计之后小于下一次联合信道估计时间窗口的长度的联合信道估计。
在本公开一些实施例中，基于第二策略执行联合信道估计包括，基于预定义规则重新确定联合信道估计时间窗口的长度，基于重新确定联合信道估计时间窗口的长度，执行联合信道估计。进一步，终端根据预定义规则确定所有重复的联合信道估计时间窗口的长度。终端可以根据重复传输次数对应的传输时间，重新对联合信道估计时间窗口的长度进行划分。
在本公开一些实施例中，基于第二策略执行联合信道估计包括，基于预定义规则，重新确定传输时间与第一参数的商值的余数对应的时间，为联合信道估计时间窗口的长度。 终端基于重新确定的时间窗口的长度，执行联合信道估计。终端根据预定义的规则，确定传输时间与第一持续时间的商值的余数，即确定执行联合信道估计之后的剩余传输时间。可针对剩余传输时间，确定执行联合信道估计的持续时间与剩余传输时间一致。例如，重复传输为14个时隙，第一参数为4个时隙，则余数为2，确定最后一次执行联合信道估计的时间窗口长度为2。
在本公开一些实施例中，基于第二策略执行联合信道估计还包括，基于重复传输的次数和联合信道估计时间窗口的长度，重新确定执行联合信道估计时间窗口的长度。示例性的，基于每个可选的重复传输次数，进行除数，确定可选的联合信道估计时间窗口的长度。
在本公开一示例性实施例中，在配置参数中，确定重复传输对应的传输时间。进一步根据预定义的运算规则，对传输时间进行运算，将得到的运算值(相对值)确定为第二参数。将第二参数确定为执行联合信道估计时间窗口的长度。
在本公开实施例中，基于预定义参数值可以对传输时间进行商运算，例如，基于预定义的参数值为4，确定的重复传输次数对应的传输时间为12，其时间可以是时隙。则确定执行联合信道估计的持续时间为3。换言之，网络侧设备可以基于每3个时隙，重复执行一次联合信道估计。
在本公开一些实施例中，若将重复传输次数的相对值，确定为执行联合信道估计的持续时间，则存在第二参数小于第一数值的情况和第二参数基于商运算之后存在余数的情况。
在本公开实施例中，针对第二参数小于第一数值的情况，可以基于第二策略执行联合信道估计。其中，第一数值可以是1。示例性的，重复传输对应的传输时间为2，网络侧设备指示的执行联合信道估计的持续时间为4，其中，时间可以是时隙。在第二持续时间为2/4，网络侧设备无法执行联合信道估计。
在本公开一些实施例中，基于第三策略执行联合信道估计包括，取消联合信道估计。即，针对第二参数小于第一数值的情况，确定取消启用联合信道估计。
在本公开一些实施例中，基于第三策略执行联合信道估计包括，可以基于预定义规则，重新确定第二参数。示例性的，在Msg3重复中，重新确定执行联合信道估计的持续时间。例如，可以是持续时间粒度的一半，或者确定固定值且小于重复传输的传输时间的固定值。
在本公开一些实施例中，基于第三策略执行联合信道估计包括，基于重复传输的传输时间重新确定执行联合信道估计时间窗口的长度。
在本公开实施例中，针对第二参数基于商运算之后存在余数的情况，可以执行第四策略。例如，重复传输的传输时间为14，重复的相对值为4，则14/4存在余数的情况。其中 时间可以时时隙。
在本公开一些实施例中，基于第四策略执行联合信道估计包括，确定执行联合信道估计的时间粒度的下限。示例性的，可以选择持续时间为3个时隙。换言之，网络侧设备可以在实际执行联合信道估计时，执行5次联合信道估计，前4次联合信道估计的持续时间为3个时隙，最后一次联合信道估计的持续时间为2个时隙。或者，网络侧设备可以执行4次联合信道估计，最后剩下的2个时隙不执行联合信道估计。
在本公开一些实施例中，基于第四策略执行联合信道估计包括，确定第二持续时间的整数倍商值。即，确定商运算的整数值，为执行联合信道估计时间窗口的长度。
在本公开一些实施例中，基于第四策略执行联合信道估计包括，基于预定义规则，重新确定第二持续时间。换言之，根据预定义规则重新确定一个定值，以该定值为基准，确定能被重复传输的传输时间整除的相对值，为执行联合信道估计时间窗口的长度。其中，该相对值可以是协议确定，或者是网络侧指示，并且该相对值小于或者大于定值。
在本公开一些实施例中，基于第四策略执行联合信道估计包括，基于重复传输的传输时间和联合信道估计的持续时间粒度，重新确定执行联合信道估计时间窗口的长度。
在本公开一些实施例中，基于第一策略执行联合信道估计包括，取消合信道估计。即，针对商运算存在余数的情况，确定取消启用联合信道估计。

在本公开一些实施例中，第二消息与第一消息部分相同。即，在终端进行msg3的重复传输时，使用初始传输的部分配置参数，或者执行联合信道的部分指示机制。示例性的，可以基于显式的指示初始传输执行联合信道估计的时间窗口，隐性的指示重复传输的时间窗口。而初始传输执行联合信道估计的时间窗口和重复传输的时间窗口，可以使用相同的消息激活。
