Description

信息指示、信息接收装置以及方法 技术领域
本申请实施例涉及通信技术领域。
背景技术
网络节能对于环境的可持续性、减少对环境的影响(温室气体排放)以及节约运营成本都具有重要意义。随着第五代移动通信技术(5th Generation Mobile Communication Technology，5G)在各行各业和地理区域的普及，处理更先进的服务和应用需要非常高的数据速率，网络部署变得更加密集，使用了更多的天线，更大的带宽和更多的频带。5G对环境的影响需要得到控制，需要开发新的解决方案来提高网络节能。
能源消耗已成为运营商运营成本的重要组成部分。根据全球移动通信***协会(GSMA)的报告，移动网络的能源成本约占运营商总成本的23％。大部分能源消耗来自于无线接入网络，特别是有源天线单元(AAU)，数据中心和光纤传输占了较小的份额。无线接入的功耗可以分为两部分：动态部分仅在数据传输/接收进行时消耗，静态部分则一直消耗，以维持无线接入设备的必要操作，即使数据传输/接收不进行。
应该注意，上面对技术背景的介绍只是为了方便对本申请的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本申请的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。

当前Release 18(R18)阶段引入了网络节能的议题。网络节能技术可以分为时域/频域/空域/能量域等类型，但在实际应用中，更可能通过两种或以上类型的节能技术相结合使用。例如，在空域节能技术方面，可以通过调整空域元素来达到节能的目的。这里的空域元素包括逻辑天线端口，发送传输单元(transmitting and receiving unit，TXRU)，发送链(Tx chain)，阵列天线因子等；在时域节能技术方面，可以通过cell ON/OFF或减少公共信号传输的方法来达到节能；在频域节能技术方面，可以通过部分带宽(bandwidth part，BWP)切换等方法实现节能。通过上述节能技术，网络设备进入节能模式(节电模式或睡眠模式)。网络设备在正常(普通)模式和节能模式之间变更时，会影响终端相关处理，包括信道状态信息(CSI)测量方式更新，信道状态信息(CSI)上报更新，信道状态信息参考信号(CSI-RS)资源更新，部分带宽(BWP)切换等。上述相关处理是网络设备调度终端设备进行数据接收和数据发送的基础。上述相关处理又涉及到网络设备对终端设备的配置、指示以及终端设备向网络设备上报。
以空域节能技术为例，可以通过调整空域元素数量来进行至少一种节能模式或者正常(普通)模式的改变，在通过调整空域元素数量达到节能的过程中终端设备可能改变CSI测量方式；此外，原则上，空域元素数量不能小于CSI-RS端口数量，否则CSI-RS不能正常配置；在通过调整空域元素数量达到节能的过程中，当节能模式开 启或关闭后，可能会造成空域元素数量小于CSI-RS端口数，进而需要更新CSI-RS时频空资源。
因此，如何使得网络设备和终端设备能够没有歧义的适应不同模式的影响是网络节能技术是否能够被应用在实际部署中的关键问题，亟待解决。针对上述问题的至少之一，本申请实施例提供一种信息指示、信息接收装置以及方法。

由此，终端设备通过指示信息能够没有歧义的适应改变的服务模式，以及准确的确定CSI测量方式更新和/或CSI上报更新和/或CSI-RS资源更新和/或BWP切换等信息，进一步高效的与网络设备进行后续上行数据的发送或者下行数据的接收。
在一些实施方式中，服务模式包括正常模式和/或至少一种节能模式。
例如，“至少一种节能模式”可以包括以下模式的至少一种：“节能模式”，“轻节能模式”，“深节能模式”，或“节能过渡模式”等，本申请对此不进行限制；上述“正常模式”还可以替换为“普通模式”；上述“节能模式”还可以替换为“节电模式”或“睡眠模式”或“非节能模式”或“关闭模式”等表述，本申请对此不进行限制。
在一些实施方式中，可以通过变更“空域元素”或者变更“天线模式”等方式改变服务模式，例如，通过关闭一部分“空域元素”使得网络从“正常模式”变更为“节能模式”。
在一些实施方式中，“空域元素”包括以下至少之一：逻辑天线端口、发送传输单元(transmitting and receiving unit，TXRU)、发送链(Tx chain)、或阵列天线因子等；在一些实施方式中，“空域元素”也可以直接替换为“节能模式”(“Power saving mode”)；“确定开启或关闭至少一部分空域元素”也可以替换为“确定开启或关闭节 能模式”；或者“确定开启或关闭至少一部分空域元素”也可以替换为“确定激活或去激活节能模式”。
在一些实施方式中，在时域节能技术方面，可以通过cell ON/OFF或减少公共信号传输的方法来达到节能。例如，通过关闭一部分小区使得网络从“正常模式”变更为“节能模式”。
在一些实施方式中，在频域节能技术方面，可以通过部分带宽(bandwidth part，BWP)切换等方法实现节能。例如，通过配置特定的部分带宽(bandwidth part，BWP)对“正常模式”或“节能模式”。
在一些实施方式中，网络设备还发送配置信息给终端设备，其中，该配置信息配置与至少一种节能模式中的一种节能模式相关的第一定时器；其中，该第一定时器设定该至少一种节能模式中的一种节能模式的作用时间。
例如，网络设备通过高层信令，例如RRC信令，发送该配置信息，其中，该配置信息通过第一定时器指示节能模式的作用时间，例如，300ms。
例如，终端设备读取RRC信令后获取该节能模式的作用时间，网络设备改变服务模式(例如，从正常模式进入节能模式)并向终端设备发送指示信息，终端设备进行CSI测量方式更新，和/或，CSI上报更新，和/或，CSI-RS资源更新，和/或，BWP切换，并且在经过300ms后恢复正常模式，后续将结合指示信息指示的具体内容分别说明。
在一些实施方式中，网络设备通过半静态信令或动态信令发送该指示信息。
例如，如果采用RRC信令发送指示信息，例如采用RRC重配流程，其实现为毫秒量级，过大的时延不利于对动态节能模式的支持，动态节能模式可以是符号或者时隙级别的(小于毫秒)；再例如，在通常情况下，一个用户的CSI-RS资源和CSI测量不需要频繁改变，但在节能操作过程中，正常模式和节能模式会频繁切换，如果使用RRC信令流程会带来很大的开销，以及造成***资源的浪费。由此，本申请上述实施方式通过半静态信令或动态信令发送该指示信息能够进一步减少信令的时延和开销，以及能够支持动态节能模式的切换。
在一些实施方式中，半静态信令可以为MAC CE信令；动态信令可以为下行控制信息(Downlink control information，DCI)。例如，该动态信令为DCI，指示信息通过该DCI承载，该DCI可以为节能模式新增的DCI格式(DCI format)，也可以重 用现有的DCI格式，本申请对此不进行限制，例如，在引入新增的DCI格式(DCI format)的情况下，可以通过引入新的无线网络临时标识(Radio Network Temporary Identity，RNTI)，例如ES-RNTI(energy saving-RNTI)对该DCI格式进行加扰，也可以为该新的DCI格式划分特定的时频资源以便终端设备能够识别该DCI，本申请对此不进行限制。
在一些实施方式中，该指示信息可以通过指示改变服务模式的信令一并发送给终端设备；例如，通过DCI对终端设备指示激活/去激活“节能模式”，可以通过该DCI一并携带该指示信息；可选的，该指示信息也可以与指示改变服务模式的信令分别发送，本申请对此不进行限制。
在一些实施方式中，该半静态信令或该动态信令为组(Group)信令，网络设备通过该组信令向多个终端设备发送指示信息；或者，该半静态信令或该动态信令为终端设备特定(UE specific)信令，网络设备通过该用户设备特定信令向一个终端设备发送指示信息。
在一些实施方式中，指示信息指示：CSI测量方式更新；和/或，CSI上报更新；和/或，CSI-RS资源更新；和/或，BWP切换。以下将示意性对上述指示信息的指示分别说明。
以下对于如何指示CSI测量方式更新进行具体说明。
例如，“CSI测量方式”为终端设备对CSI测量结果进行“合并处理”或者“不合并处理”；例如，“合并处理”也可以替换为“合并平均”或者“平滑滤波”；其中，“合并处理”或者“平滑滤波”的具体实施方式可以参见现有的技术，本申请对此不进行限制。
例如，在“正常模式”(“非节能模式”)下，终端设备通常会对所有CSI测量结果进行合并处理；但是，在开启“节能模式”的情况下，信道状态指示参考信号(CSI-RS)的传输功率会发生变化，在“正常模式”向“节能模式”变更之后的最近一次CSI测量方式也应该相应地变化，来实时反映信道质量状态。例如，在“正常模式”变更为“节能模式”时，如果终端设备仍然对CSI测量结果做合并处理，可能会对“正常模式”和“节能模式”的CSI测量结果进行合并，因此会导致合并后的CSI测量结果无法真实地反映节能模式的信道状态。而本申请实施方式能够通过该指示信息使得终端设备及时获取CSI测量方式更改或者不更改，由此，能够更加准确的进行CSI测量。
在一些实施方式中，网络设备通过指示CSI测量方式更新的指示信息和/或第一定时器指示CSI测量方式更改或者不更改。
在一些实施方式中，在网络设备改变服务模式的情况下，该指示信息通过一个或多个比特的一个取值指示更改CSI测量方式，和/或，通过该一个或多个比特的另一个取值指示不更改所述CSI测量方式。
在一些实施方式中，在半静态信令或动态信令为组信令的情况下，该指示信息为包括多个块的位图(bitmap)。
例如，每个块对应一个终端设备，每个块的起始位置和/或大小由高层信令配置。
图3为本申请实施例指示信息的一示例图。
例如，每个块(block)代表一个终端设备的指示信息，每个块(block)的起始位置和/或大小由高层参数给出，例如可以使用现有标准中的高层参数，也可以引入新的高层参数，本申请对此不进行限制。
以每个块为1比特为例，其中，网络设备可以通过1比特来指示特定终端设备CSI测量方式更改或者不更改，例如，该比特为“1”，为更改该CSI测量方式，也可以说，不进行CSI测量合并处理；该比特为“0”，为不更改该CSI测量方式，也可以说，进行CSI测量合并处理。
例如，对于五个终端设备，指示信息的具体内容为“11010”的含义即为：对于第一个、第二个、第四个终端设备，不进行CSI测量合并处理；对于第三个、第五个终端设备，进行CSI测量合并处理。以第三个终端设备为例，该第三个终端设备通过高层信令获得该指示信息一共为5比特，其中，每个块的大小为1比特，因此该第三个终端设备可以确定第三个比特(取值为“0”)为该第三个终端设备的指示比特。
在一些实施方式中，如果终端设备的CSI测量方式发生更改，该指示信息携带该终端设备对应的块；如果终端设备的CSI测量方式不发生更改，该指示信息不携带该终端设备对应的块。例如，该终端设备通过高层信令未读取到该指示信息的相关字段，则认为CSI测量方式不更改，仍然使用原本的CSI测量方式。
在一些实施方式中，在半静态信令或动态信令为终端设备特定信令的情况下。例如，网络设备可以通过1比特来指示CSI测量方式更改或者不更改，例如，该比特为“1”，为更改该CSI测量方式，也可以说，不进行CSI测量合并处理；该比特为“0”，为不更改该CSI测量方式，也可以说，进行CSI测量合并处理。
上述比特内容仅为示例性说明，也可以设置为比特为“0”，为更改该CSI测量方式，也可以说，不进行CSI测量合并处理；该比特为“1”，为不更改该CSI测量方式，本申请对此不进行限制。
在一些实施方式，终端设备在第一定时器超时后更改CSI测量方式。
例如，网络设备通过高层信令，例如RRC信令，发送该配置信息，其中，该配置信息指示节能模式的作用时间。例如，终端设备读取RRC信令后获取该节能模式的作用时间，网络设备改变服务模式(例如，从正常模式进入节能模式)并向终端设备发送指示信息(采用上述的指示方法)，终端设备进行CSI测量方式更新，例如正常模式变更到节能模式时不进行合并处理，并且在经过300ms后恢复正常模式，以及更改CSI测量方式，例如，300ms到期时的CSI测量不进行合并处理。
由此，终端设备能够获取指示信息的具体内容，能够更加准确的进行CSI测量。
以下对于如何指示CSI上报更新进行具体说明。
在一些实施方式中，网络设备通过指示CSI上报更新的指示信息和/或第一定时器激活/去激活至少一个CSI上报。
在一些实施方式中，在网络设备改变服务模式的情况下，指示信息指示激活第一CSI上报和/或去激活第二CSI上报，其中，该第一CSI上报和/或该第二CSI上报由高层信息配置。
在一些实施方式中，该第一CSI上报和/或该第二CSI上报属于第一CSI上报列表，该第一CSI上报列表包括CSI上报配置索引(CSI-ReportConfigId)，其中，该第一CSI上报列表和该CSI上报配置索引(CSI-ReportConfigId)由高层信息配置。
例如，每个CSI上报与CSI上报配置索引(CSI-ReportConfigId)对应，例如，CSI上报配置索引(CSI-ReportConfigId)＝0对应的CSI上报为：CSI 0。
例如，该第一CSI上报列表包含哪些CSI上报是通过高层信令配置的，例如，高层信令配置第一CSI上报列表包含5个CSI上报，分别对应“CSI 0”-“CSI 4”；终端设备根据指示信息确定激活/去激活哪个具体的CSI上报，说明书将在后续内容将进一步结合实施方式举例说明。
在一些实施方式中，该第一CSI上报列表包括的CSI上报配置索引(CSI-ReportConfigId)与以下至少一个信息的变更关联：
CSI上报周期以及偏移(offset)，例如通过高层信令的如下字段指示“CSI-ReportPeriodicityAndOffset”，“reportSlotConfig”和“reportSlotOffsetList”；
CSI上报使用的资源，例如通过高层信令的如下字段指“pucch-CSI-ResourceList”指示；
CSI上报绑定的CSI-RS Resource的周期以及偏移(offset)，例如通过高层信令的如下字段指示“ResourceConfig”；或CSI-
CSI上报绑定的CSI-RS Resource的时频资源，例如通过高层信令的如下字段指示“CSI-ResourceConfig”。
例如，在节能模式下的CSI上报的周期可以较长，例如，正常模式下的CSI上报周期为40ms，节能模式下的CSI周期为80m；例如，高层配置了CSI 0的周期为80ms，CSI 1的周期为40ms，以及第一CSI上报列表包括CSI 0和CSI 1，在服务模式改变为节能模式后，指示信息可以指示激活CSI 0(第一CSI上报)以及去激活CSI 1(第二CSI上报)，说明书将在后续内容将进一步结合实施方式举例说明。
再例如，在节能模式下的CSI上报绑定的CSI-RS资源为CSI-RS 16port，正常模式下的CSI上报绑定的CSI-RS资源为CSI-RS 32port，例如，高层配置了CSI 0绑定32port的CSI-RS 0，CSI 1绑定16port的CSI-RS 1，以及第一CSI上报列表包括CSI 0和CSI 1，在服务模式改变为节能模式后，指示信息可以指示激活CSI 1(第一CSI上报)以及去激活CSI 0(第二CSI上报)，激活CSI 1也意味着同样激活其绑定的16port的CSI-RS 1，去激活CSI 0也意味着同样去激活其绑定的32port的CSI-RS 0。
在一些实施方式中，对于一个特定CSI上报，指示信息通过一个或多个比特的一个取值指示激活该CSI上报，通过该一个或多个比特的另一个取值指示去激活该CSI上报。
在一些实施方式中，在半静态信令或动态信令为组信令的情况下，该指示信息为包括多个块的位图；其中，每个块对应一个终端设备，每个块的起始位置和/或大小由高层信令配置，每个块包括一个或多个比特，每个块指示终端设备的该第一CSI上报列表，每个块中的每个比特对应该第一CSI上报列表中的CSI上报。
例如，仍然以图3所示的多个块的位图为例，每个块(block)代表一个终端设备的指示信息，每个块(block)的起始位置和/或大小由高层参数给出，例如可以使 用现有标准中的高层参数，也可以引入新的高层参数，本申请对此不进行限制。
例如，每个块(block)对应一个特定终端设备的第一CSI上报列表，每个块例如包括X比特，其中，该X比特的每一个比特对应该第一CSI上报列表中的一个CSI上报的激活/去激活的状态，该列表可以由高层参数给出。
以一个特定终端设备为例，例如，高层参数配置了第一CSI上报列表包含5个CSI上报，分别对应“CSI 0”-“CSI 4”，通过5个比特指示每个CSI上报的激活/去激活状态，例如，“0”代表去激活CSI上报，“1”代表激活CSI上报；例如，高层参数配置了“CSI 0”(第一CSI上报)的CSI周期为80m，“CSI 1”-“CSI 4”(第二CSI上报)的CSI周期为40m，可以发送“10000”给用户设备，其含义为激活“CSI 0”，去激活“CSI 1”-“CSI 4”。
例如，对于五个终端设备，指示信息为“‘10000’‘10100’‘00011’‘00100’‘10001’”；以第二个终端设备为例，该第二个终端设备通过高层信令获得该指示信息一共为25比特，起始位置为第6比特，并且本终端指示信息大小为5比特，即第六至第十比特为该第二个终端设备的指示比特；其中，‘10100’指示的是对于第二个终端设备，激活“CSI 0”(第一CSI上报)以及“CSI 2”(第一CSI上报)，去激活“CSI 1”(第二CSI上报)、“CSI 3”(第二CSI上报)、“CSI 4”(第二CSI上报)。以上仅为示例性说明，例如，对于不同的终端设备的第一CSI上报列表可以不同。
在一些实施方式中，如果终端设备的CSI上报激活/去激活状态需要更新，该指示信息携带该终端设备对应的块；如果终端设备的CSI上报激活/去激活状态不需要更新，该指示信息不携带该终端设备对应的块。例如，该终端设备通过高层信令未读取到该指示信息的相关字段，则认为CSI上报激活/去激活状态不需要更新。
上述比特内容仅为示例性说明，也可以设置“0”代表激活CSI上报，“1”代表去激活CSI上报，本申请对此不进行限制。
在一些实施方式中，该第一CSI上报和/或该第二CSI上报包括：周期性的CSI上报、半持续的CSI上报、或非周期性的CSI上报；例如，周期性的CSI上报、半持续的CSI上报、或非周期性的CSI上报的具体内容可以参见现有技术，本申请对此不进行限制。
图4是本申请实施例CSI上报的一示例图。
例如，对于一个特定终端设备，在终端设备处于正常模式的情况下，其被配置的 CSI上报为“CSI 0”，其绑定的CSI-RS资源为“CSI-RS 0”；在终端设备处于节能模式的情况下其被配置的CSI上报为“CSI 1”，其绑定的CSI-RS资源为“CSI-RS 1”；例如，结合上述更新CSI上报的方法，在改变服务模式进入节能模式的情况下，网络设备发送的指示信息为“…‘01000’….”，对应更新的激活的CSI上报为“CSI 1”；例如，在改变服务模式进入正常模式的情况下，发送的指示信息为“…‘10000’….”，对应更新的激活的CSI上报为“CSI 0”。
在一些实施方式中，在半静态信令或动态信令为终端设备特定信令的情况下。例如，网络设备可以通过X比特来指示第一CSI上报列表；该X比特中的每个比特指示具体的激活CSI上报或者去激活CSI上报，例如，“1”为激活CSI上报；“0”为去激活CSI上报。例如，采用上述实施方式的每个块的内容作为终端设备特定信令的具体内容进而发送给特定的终端设备，对于具体的指示方法可以参见上述实施方式，在此不做重复说明。
在一些实施方式，终端设备在服务模式变更时，开启第一定时器并挂起服务模式改变前的CSI上报；以及该终端设备在第一定时器超时后恢复该服务模式改变前的CSI上报
例如，网络设备通过高层信令，例如RRC信令，发送该配置信息，其中，该配置信息指示节能模式的作用时间。例如，终端设备读取RRC信令后获取该节能模式的作用时间，网络设备改变服务模式(例如，从正常模式进入节能模式)并向终端设备发送指示信息(采用上述的指示方法)，终端设备更新了激活/去激活的CSI上报并且挂起正常模式下激活/去激活的CSI上报，并且在经过300ms，即第一定时器超时后恢复正常模式，以及恢复正常模式下激活/去激活的CSI上报。
由此，终端设备能够获取指示信息的具体内容，能够确定CSI上报更新。
以下对于如何指示CSI-RS资源更新进行具体说明。
在一些实施方式中，网络设备通过指示CSI-RS资源更新的指示信息和/或第一定时器激活/去激活至少一个CSI-RS资源。
在一些实施方式中，在网络设备改变服务模式的情况下，指示信息指示激活第一CSI-RS资源和/或去激活第二CSI-RS资源，其中，该第一CSI-RS资源和/或该二CSI-RS资源由高层信息配置；其中，该第一CSI-RS资源和/或所述第二CSI-RS资源是相同的或是不同的。
在一些实施方式中，该第一CSI-RS资源和/或该第二CSI-RS资源属于第一CSI-RS资源集合，其中，该第一CSI-RS资源集合包括CSI-RS资源(CSI-RS resource)，和/或，CSI-RS端口(CSI-RS port)；其中，该第一CSI-RS资源集合的索引以及该第一CSI-RS资源集合包括的CSI-RS资源(CSI-RS resource)的个数和索引，和/或，该CSI-RS端口(CSI-RS port)的个数和/或索引由高层信息配置。
例如，高层信令配置了该第一CSI-RS资源集合及其索引，以及该第一CSI-RS资源集合下包含多个CSI-RS resource和多个CSI-RS port以及相关配置，其中，多个CSI-RS resource和多个CSI-RS port相关配置可以参见现有技术，本申请对此不进行限制。
以下以该第一CSI-RS资源和/或该第二CSI-RS资源属于第一CSI-RS资源集合，其中，该第一CSI-RS资源集合包括CSI-RS资源(CSI-RS resource)为例。
在一些实施方式中，对于一个特定CSI-RS资源(CSI-RS resource)，指示信息通过一个或多个比特的一个取值指示激活CSI-RS资源(CSI-RS resource)，该指示信息通过一个或多个比特的另一个取值指示去激活CSI-RS资源(CSI-RS resource)。
在一些实施方式中，该CSI-RS资源(CSI-RS resource)包括一组CSI-RS资源(CSI-RS resource)或者一个CSI-RS资源(CSI-RS resource)，该一组CSI-RS资源(CSI-RS resource)由高层信令配置。
在一些实施方式中，在半静态信令或动态信令为组信令的情况下，该指示信息为包括多个块的位图；其中每个块对应一个终端设备，每个块的起始位置和/或大小由高层信令配置；每个比特对应该终端设备的一组CSI-RS资源(CSI-RS resource)或者一个CSI-RS资源(CSI-RS resource)，该比特的个数由高层信令配置。
例如，仍然以图3所示的多个块的位图为例，每个块(block)代表一个终端设备的指示信息，每个块(block)的起始位置和/或大小由高层参数给出，例如可以使用现有标准中的高层参数，也可以引入新的高层参数，本申请对此不进行限制。
例如，每个块(block)对应一个特定终端设备的一个CSI-RS资源集合(CSI-RS resource set)中的各个CSI-RS资源(CSI-RS resource)的激活/去激活的状态，例如，每个块包括X比特，其中该X比特的每一个比特对应CSI-RS资源(CSI-RS resource)的激活/去激活的状态。在一些实施方式中，CSI-RS资源集合(CSI-RS resource set)及其对应的CSI-RS资源(CSI-RS resource)的具体设置可以参见现有技术，本申请 对此不进行限制。
例如，第一CSI-RS资源集合(CSI-RS resource set)中包括4个CSI-RS资源(CSI-RS resource)，通过4个比特指示每个CSI-RS资源(CSI-RS resource)的激活/去激活状态，例如，“0”代表去激活该CSI-RS资源(CSI-RS resource)，“1”代表激活该CSI-RS资源(CSI-RS resource)；“1010”的含义为激活“CSI-RS资源0”(第一CSI-RS资源)、“CSI-RS资源2”(第一CSI-RS资源)，去激活“CSI-RS资源1”(第二CSI-RS资源)、“CSI-RS资源3”(第二CSI-RS资源)。
例如，对于两个终端设备，指示信息为“‘1010’‘0101’”；以第一个终端设备为例，该第一个终端设备通过高层信令获得该指示信息一共为8比特起始位置为第1比特，并且持续4比特，即第一至第四比特为该第一个终端设备的指示比特；其中，‘1010’指示的是对于第一个终端设备，激活“CSI-RS资源0”、“CSI-RS资源2”，去激活“CSI-RS资源1”、“CSI-RS资源3”。
可选的，该指示信息还可以指示一组CSI-RS资源(CSI-RS resource)的激活/去激活状态，例如，“CSI-RS资源0”、“CSI-RS资源2”为组0(Group 0)；“CSI-RS资源1”、“CSI-RS资源3”为组1(Group 1)；对于两个终端设备，指示信息为“‘10’‘01’”；以第一个终端设备为例，该第一个终端设备通过高层信令获得该指示信息一共为4比特，其中，每个块的大小为2比特以及“CSI-RS资源0”、“CSI-RS资源2”为组0(Group 0)，“CSI-RS资源1”、“CSI-RS资源3”为组1(Group 1)，并且第一至第二比特为该第一个终端设备的指示比特；其中，‘10’指示的是对于第一个终端设备，激活“CSI-RS资源0”、“CSI-RS资源2”，去激活“CSI-RS资源1”、“CSI-RS资源3”。
在一些实施方式中，如果终端设备的CSI-RS资源(CSI-RS resource)的激活/去激活状态需要更新，该指示信息携带该终端设备对应的块；如果终端设备的CSI-RS资源(CSI-RS resource)的激活/去激活状态不需要更新，该指示信息不携带该终端设备对应的块。例如，该终端设备通过高层信令未读取到该指示信息的相关字段，则认为CSI-RS资源(CSI-RS resource)的激活/去激活状态不需要更新。
上述比特内容仅为示例性说明，也可以设置“0”代表激活CSI-RS资源(CSI-RS resource)，“1”代表去激活CSI-RS资源(CSI-RS resource)，本申请对此不进行限制。
图5是本申请实施例CSI-RS resource更新的一示例图。
如图5所示，对于32端口CSI-RS，例如，可以通过CDM-4以及4个resource的方式来支持32端口CSI-RS，其中，CDM-4的一个resource占据8个资源元素(resource element，RE)，CDM-4可以参考现有技术，本申请对此不进行限制。在正常模式下，特定终端设备采用32端口CSI-RS，在节能模式下，该终端设备采用16端口CSI-RS，例如，在网络设备关闭部分空域元素的情况下，终端设备的CSI-RS资源由图5中的激活“资源1(Resource 1)-资源4(Resource 4)”变更为激活“资源1(Resource 1)、资源3(Resource3)”，去激活“资源2(Resource 2)、资源4(Resource4)”。由此，能够实现32port CSI-RS资源到16port CSI-RS资源的更新；例如，采用上述指示的方式，在此不做重复说明。
在一些实施方式中，在半静态信令或动态信令为终端设备特定信令的情况下。例如，网络设备可以通过X比特来指示一个CSI-RS资源集合(CSI-RS resource set)包含的CSI-RS资源(CSI-RS resource)的激活/去激活状态；该X比特中的每个比特指示具体的CSI-RS资源(CSI-RS resource)的激活/去激活状态，例如，“1”为激活CSI-RS资源(CSI-RS resource)；“0”为去激活CSI-RS资源(CSI-RS resource)；可选的，网络设备可以通过X比特来指示一个CSI-RS资源集合(CSI-RS resource set)包含的多组CSI-RS资源(CSI-RS resource)的激活/去激活状态。例如，采用上述实施方式的每个块的内容作为终端设备特定信令的具体内容进而发送给特定的终端设备，对于具体的指示方法可以参见上述实施方式，在此不做重复说明。
在一些实施方式，终端设备在第一定时器超时后挂起服务模式改变前的CSI-RS资源；以及该终端设备在第一定时器超时后恢复该服务模式改变前的CSI-RS资源。
例如，网络设备通过高层信令，例如RRC信令，发送该配置信息，其中，该配置信息指示节能模式的作用时间。例如，终端设备读取RRC信令后获取该节能模式的作用时间，网络设备改变服务模式(例如，从正常模式进入节能模式)并向终端设备发送指示信息(采用上述的指示方法)，终端设备更新激活/去激活的CSI-RS资源并且挂起正常模式激活/去激活的CSI-RS资源，并且在经过300ms第一定时器超时后恢复正常模式，以及恢复正常模式下激活/去激活的CSI-RS资源。
由此，终端设备能够获取指示信息的具体内容，能够确定更新的激活/去激活的CSI-RS资源(CSI-RS resource)。
以下以该第一CSI-RS资源和/或该第二CSI-RS资源属于第一CSI-RS资源集合， 其中，该第一CSI-RS资源集合包括CSI-RS端口(CSI-RS port)为例。
在一些实施方式中，指示信息通过一个或多个比特的一个取值指示去激活该CSI-RS端口，通过该一个或多个比特的另一个取值指示激活该CSI-RS端口。

例如，仍然以图3所示的多个块的位图为例，每个块(block)代表一个终端设备的指示信息，每个块(block)的起始位置和/或大小由高层参数给出，例如可以使用现有标准中的高层参数，也可以引入新的高层参数，本申请对此不进行限制。
例如，每个块(block)对应一个特定终端设备的CSI-RS端口(port)的激活/去激活的状态，例如，每个块例如包括X比特，其中该X比特的每一个比特对应CSI-RS端口(port)的激活/去激活的状态。在一些实施方式中，CSI-RS端口(port)的具体设置可以参见现有技术，本申请对此不进行限制。
可选的，该每个块例还可以包括CSI-RS资源(CSI-RS resource)相关信息，例如包括T比特(T可以等于0)，该T比特指示CSI-RS端口(port)对应的CSI-RS资源组(CSI-RS resource set)和/或CSI-RS资源(CSI-RS resource)，可选的在T＝0的情况下，CSI-RS端口(port)对应的CSI-RS资源组(CSI-RS resource set)和/或CSI-RS资源(CSI-RS resource)由高层信息指示。
以下以T＝0，即，不指示CSI-RS端口(port)对应的CSI-RS资源组(CSI-RS resource set)和/或CSI-RS资源(CSI-RS resource)作为示例进行说明。
例如，对于一个终端设备能够被配置32CSI-RS端口，通过32个比特指示CSI-RS端口的激活/去激活状态，例如，“0”代表去激活该CSI-RS端口，“1”代表激活该CSI-RS端口；“00000000000000001111111111111111”的含义为激活“CSI-RS端口16”-“CSI-RS端口31”，去激活“CSI-RS端口0”-“CSI-RS端口15”；可选的，该指示信息还可以指示一组CSI-RS端口的激活/去激活状态，这一组CSI-RS端口可以是一个或多个CDM组，例如，“CSI-RS端口0”-“CSI-RS端口15”为组0(Group 0)； “CSI-RS端口16”-“CSI-RS端口31”为组1(Group 1)，或者CSI-RS32端口共4个CDM组，“CDM组0”和“CDM组1”为组0(Group 0)，“CDM组2”和“CDM组3”为组1(Group 1)。
例如，对于两个终端设备，指示信息为“‘10’‘01’”；以第一个终端设备为例，该第一个终端设备通过高层信令获得该指示信息一共为4比特，该终端设备对应的起始位置为第1比特，共2比特以及“CSI-RS端口0”-“CSI-RS端口15”为组0(Group0)；“CSI-RS端口16”-“CSI-RS端口31”为组1(Group 1)，并且第一至第二比特为该第一个终端设备的指示比特；其中，‘10’指示的是对于第一个终端设备，激活“CSI-RS端口0”-“CSI-RS端口15”，去激活“CSI-RS端口16”-“CSI-RS端口31”。
此外，对于T不等于0的情况，可以结合上述激活/去激活CSI-RS端口(port)和上述激活/去激活CSI-RS resource的方式进行指示，本申请在此不做重复。
在一些实施方式中，如果终端设备的CSI-RS端口的激活/去激活状态需要更新，该指示信息携带该终端设备对应的块；如果终端设备的CSI-RS端口不需要更新，该指示信息不携带该终端设备对应的块。例如，该终端设备通过高层信令未读取到该指示信息的相关字段，则认为CSI-RS端口的激活/去激活状态不需要更新。
上述比特内容仅为示例性说明，也可以设置“0”代表激活CSI-RS端口，“1”代表去激活CSI-RS端口，本申请对此不进行限制。
图6是本申请实施例CSI-RS端口更新的一示例图。
如图6所示，对于32端口CSI-RS，例如，可以通过4个CDM-8以及1个resource的方式来支持32端口CSI-RS，其中，CDM-8的一个resource占据32个资源元素(resource element，RE)，CDM-8可以参考现有技术，本申请对此不进行限制。在正常模式下，特定终端设备采用32端口CSI-RS，在节能模式下，该终端设备采用16端口CSI-RS，例如，在网络设备关闭部分空域元素的情况下，终端设备的CSI-RS资源由图6中的“激活CSI-RS端口0-31”变更为“激活CSI-RS端口0-15”由此，能够实现32port CSI-RS到16port CSI-RS的更新；例如，采用上述指示的方式，在此不做重复说明。
在一些实施方式中，在半静态信令或动态信令为终端设备特定信令的情况下。例如，网络设备可以通过X比特来指示CSI-RS端口激活/去激活状态；该X比特中的每个比特指示具体的CSI-RS端口的激活/去激活状态，例如，“1”为激活CSI-RS端 口；“0”为去CSI-RS资源(CSI-RS resource)；可选的，网络设备可以通过X比特来指示多组CSI-RS端口的激活/去激活状态。例如，采用上述实施方式的每个块的内容作为终端设备特定信令的具体内容进而发送给特定的终端设备，对于具体的指示方法可以参见上述实施方式，在此不做重复说明。
在一些实施方式，终端设备在第一定时器超时后挂起服务模式改变前的CSI-RS端口；以及该终端设备在第一定时器超时后恢复该服务模式改变前的CSI-RS端口。
例如，网络设备通过高层信令，例如RRC信令，发送该配置信息，其中，该配置信息指示节能模式的作用时间。例如，终端设备读取RRC信令后获取该节能模式的作用时间，网络设备改变服务模式(例如，从正常模式进入节能模式)并向终端设备发送指示信息(采用上述的指示方法)，终端设备更新激活/去激活CSI-RS端口并且挂起正常模式的激活/去激活的CSI-RS端口，并且在经过300ms第一定时器超时后恢复正常模式，以及恢复正常模式下激活/去激活的CSI-RS端口。
由此，终端设备能够获取指示信息的具体内容，能够确定更新的激活/去激活的CSI-RS端口(CSI-RS端口)。
以下对于如何指示BWP切换进行具体说明。
在一些实施方式中，网络设备通过指示BWP切换的指示信息和/或第一定时器指示服务模式变更后的BWP。
在一些实施方式中，在网络设备改变服务模式的情况下，指示信息指示服务模式变更后的BWP索引；其中，该BWP索引由高层信息配置。
在一些实施方式中，BWP索引与CSI上报配置索引(CSI-ReportConfigId)关联；其中，该BWP索引关联的所述CSI上报配置索引(CSI-ReportConfigId)由高层信息配置。
在一些实施方式中，在网络设备改变服务模式的情况下，切换至激活服务模式变更后的BWP索引对应的BWP，同时激活关联的CSI上报配置索引(CSI-ReportConfigId)关联的CSI上报，去激活服务模式变更前的BWP索引关联的CSI上报配置索引(CSI-ReportConfigId)关联的CSI上报。
在一些实施方式中，在半静态信令或动态信令为组信令的情况下，该指示信息为包括多个块的位图；其中每个块对应一个终端设备，每个块的起始位置和/或大小由高层信令配置；其中，每个块包括一个或多个比特，指示终端设备该切换的BWP的 索引(index)。
例如，仍然以图3所示的多个块的位图为例，每个块(block)代表一个终端设备的指示信息，每个块(block)的起始位置和/或大小由高层参数给出，例如可以使用现有标准中的高层参数，也可以引入新的高层参数，本申请对此不进行限制。
例如，每个块(block)对应开启或关闭至少一部分空域元素的情况下，终端设备即将要切换的BWP的索引(index)，例如，每个块包括X比特，其对应一个BWP的索引。在一些实施方式中，BWP的设置和其索引可以参见现有技术，本申请对此不进行限制。
例如，一个终端设备被配置了4个BWP，指示信息通过2个比特指示切换的BWP索引，例如，“00”代表切换到BWP 0，“01”代表切换到BWP 1，“10”代表切换到BWP 2，“11”代表切换到BWP 3。例如，高层信令配置了BWP 0与CSI 0关联，BWP 1与CSI1关联，在服务模式变更为节能模式后，例如指示信息指示了“00”下，对应激活CSI 0，去激活终端设备正常模式下的CSI上报，例如，去激活高层信令配置的正常模式下的CSI 1。
例如，对于两个终端设备，在服务模式变更的情况下，指示信息为“‘10’‘01’”；以第一个终端设备为例，该第一个终端设备通过高层信令获得该指示信息一共为4比特，其中，每个块的大小为2比特，并且第一至第二比特为该第一个终端设备的指示比特；其中，‘10’指示的是对于第一个终端设备，切换到BWP 2。
在一些实施方式中，如果终端设备的BWP需要切换，该指示信息携带该终端设备对应的块；如果终端设备的BWP不需要切换，该指示信息不携带该终端设备对应的块。例如，该终端设备通过高层信令未读取到该指示信息的相关字段，则认为终端设备的BWP不需要切换。
在一些实施方式，终端设备挂起服务模式改变前的BWP索引；以及终端设备在第一定时器超时后恢复服务模式改变前的BWP索引。
例如，网络设备通过高层信令，例如RRC信令，发送该配置信息，其中，该配置信息指示节能模式的作用时间。例如，终端设备读取RRC信令后获取该节能模式的作用时间，网络设备改变服务模式(例如，从正常模式进入节能模式)并向终端设备发送指示信息(采用上述的指示方法)，终端设备切换的BWP索引并且挂起正常模式下的BWP索引，并且在经过300ms第一定时器超时后恢复正常模式，切换回正常 模式下的BWP索引。
由此，终端设备能够获取指示信息的具体内容，能够确定切换的BWP索引。
值得注意的是，以上附图4-图6仅对本申请实施例进行了示意性说明，但本申请不限于此。例如可以适当地调整各个操作之间的执行顺序，此外还可以增加其他的一些操作或者减少其中的某些操作。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图4-图6的记载。
由上述实施例可知，网络设备改变服务模式以及向终端设备发送指示信息，其中，指示信息指示：CSI测量方式更新；和/或，CSI上报更新；和/或，CSI-RS资源更新；和/或，BWP切换。由此，终端设备通过指示信息能够没有歧义的适应改变的服务模式，以及准确的确定CSI测量方式更新和/或CSI上报更新和/或CSI-RS资源更新和/或BWP切换等信息，进一步高效的与网络设备进行后续上行数据的发送或者下行数据的接收。
