- a combination of multiple systems for example, a combination of
- the time domain CSI prediction (predicted) of the AI/ML-based model (UE side CSI prediction model) on the terminal 101 side can be used.
- the time slot (slot) t1 in which the network device 102 sends CSI resources such as CSI Reference Signal (CSI-RS), the time slot t2 in which the terminal 101 reports CSI according to CSI-RS, and the time slot t3 in which the network device 102 performs downlink transmission (DL transmission) based on CSI are different.
- the CSI obtained by the network device 102 may be outdated, which may cause inaccurate downlink precoding, thereby affecting the throughput of the system, especially for high mobility scenarios.
- the AI/ML model in the AI/ML-based CSI prediction, can be used to predict the channel state at a certain time in the future to make up for the time difference between t1 and t3 in FIG1b.
- the network device 102 if it is to obtain CSI at certain corresponding times, it is necessary to send CSI-RS at these times.
- the original CSI-RS configuration indicates that the period of the CSI-RS is P1, so there is a CSI-RS at time t1, time (t1+P1), time (t1+2P1), etc. If the network device 102 expects to obtain the CSI at time t2, there needs to be a CSI-RS at time t2. Therefore, based on the original CSI-RS configuration, the CSI-RS at time t2 needs to be reconfigured.
- the prediction model on the terminal 101 side can predict the CSI at time t2 based on the originally configured CSI-RS, thereby reducing the CSI-RS configured outside the original period at time t2 and saving CSI-RS overhead.
- the CSI-RS of the original configuration period is adjusted by reconfiguring or configuring CSI-RS of different periods for combination. In this case, multiple times or multiple sets of CSI-RS configurations are required.
- a CSI report may correspond to multiple CSI-RS, but the expression of one of the CSI-RS More specifically, for the associated CSI report and CSI-RS, it is necessary to determine the CSI-RS corresponding to a certain CSI report through a CSI reference resource (CSI Reference Resource).
- CSI Reference Resource CSI Reference Resource
- the CSI report content needs to be calculated using the CSI resource (dashed box) before the CSI reference resource.
- the terminal 101 can autonomously select one of the CSI resources in the dashed box.
- the terminal 101 can select the last CSI resource in the dashed box to calculate the CSI report.
- a short-period CSI-RS can be used for data collection in the model training phase, and a long-period CSI-RS can be used to configure CSI prediction in the model deployment phase.
- the network device 102 needs to be configured separately, that is, configure a short-period CSI-RS, and then reconfigure a long-period CSI-RS for the terminal 101 or activate the configured long-period CSI-RS.
- Radio Resource Control RRC
- the required delay is relatively long, and at least two new CSI-RS may need to be configured.
- MU-MIMO Multi-User Multiple-Input Multiple-Output
- RRC can be used for reconfiguration to change the original short-period CSI-RS to a long-period one, which requires a longer response time and may still require the configuration of a new CSI-RS.
- RRC can be used for reconfiguration to change the original short-period CSI-RS to a long-period one, which requires a longer response time and may still require the configuration of a new CSI-RS.
- the model needs to collect data again, switching from a long period back to the original short-period CSI-RS time domain characteristics requires a longer response time, affecting system performance.
- the network device 102 activates the configured long-period CSI-RS and deactivates or releases the current short-period CSI-RS. At this time, it may still be necessary to configure a new CSI-RS.
- each terminal 101 using CSI prediction needs to be reconfigured as above, that is, each short-period CSI-RS is configured with at least two long-period CSI-RS candidates, since a terminal 101 can be configured with a maximum of 64 CSI-RSs, if it is necessary to implement predictions of multiple different time domain characteristics on the terminal 101 side, it is likely that the number of CSI-RSs allowed to be configured is insufficient.
- a configuration enhancement method for reducing CSI-RS overhead for time domain CSI prediction at the UE side is provided.

本公开实施例中,在基于AI的CSI增强中,可使用终端101侧的基于AI/ML的模型(UE side CSI prediction model)的时域CSI预测(predicted)。In the disclosed embodiment, in the AI-based CSI enhancement, the time domain CSI prediction (predicted) of the AI/ML-based model (UE side CSI prediction model) on the terminal 101 side can be used.
本公开实施例中,参考图1b所示,由于存在处理时延或调度时延,CSI应用过程中存在信道老化(Channel Aging)的问题。网络设备102发送CSI资源如CSI参考信号(CSI Reference Signal,CSI-RS)的时隙(slot)t1、终端101根据CSI-RS进行CSI上报(CSI report)的时隙t2以及网络设备102基于CSI进行下行传输(DL transmission)的时隙t3不同。其中,与网络设备102进行下行传输的时隙相比,网络设备102在所获得的CSI可能是过时的,此时可能导致下行预编码不准确,从而影响系统的吞吐量,特别是对于高移动性的场景而言。In the disclosed embodiment, as shown in reference to FIG1b, due to the existence of processing delay or scheduling delay, there is a problem of channel aging in the CSI application process. The time slot (slot) t1 in which the network device 102 sends CSI resources such as CSI Reference Signal (CSI-RS), the time slot t2 in which the terminal 101 reports CSI according to CSI-RS, and the time slot t3 in which the network device 102 performs downlink transmission (DL transmission) based on CSI are different. Among them, compared with the time slot in which the network device 102 performs downlink transmission, the CSI obtained by the network device 102 may be outdated, which may cause inaccurate downlink precoding, thereby affecting the throughput of the system, especially for high mobility scenarios.
本公开实施例中,参考图1c所示,在基于AI/ML的CSI预测中,可以通过AI/ML模型预测出未来某时刻的信道状态,以弥补图1b中t1与t3之间的时间差。对于网络设备102而言,若要获得某些对应时刻的CSI,须在这些时刻上发送CSI-RS。In the embodiment of the present disclosure, as shown in FIG1c, in the AI/ML-based CSI prediction, the AI/ML model can be used to predict the channel state at a certain time in the future to make up for the time difference between t1 and t3 in FIG1b. For the network device 102, if it is to obtain CSI at certain corresponding times, it is necessary to send CSI-RS at these times.
本公开实施例中,参考图1d所示,原CSI-RS配置指示CSI-RS的周期为P1,因此在t1时刻、(t1+P1)时刻、(t1+2P1)时刻等存在CSI-RS。若网络设备102期待获得t2时刻的CSI,则需要在t2时刻存在一个CSI-RS。因此在原CSI-RS配置的基础上,需要重新配置在t2时刻的CSI-RS。In the embodiment of the present disclosure, as shown in FIG. 1d, the original CSI-RS configuration indicates that the period of the CSI-RS is P1, so there is a CSI-RS at time t1, time (t1+P1), time (t1+2P1), etc. If the network device 102 expects to obtain the CSI at time t2, there needs to be a CSI-RS at time t2. Therefore, based on the original CSI-RS configuration, the CSI-RS at time t2 needs to be reconfigured.
参考图1e所示,在基于AI/ML的CSI预测中,终端101侧的预测模型可以根据原配置的CSI-RS预测出该t2时刻的CSI,因此可以减少在该t2时刻配置原周期外的CSI-RS,节约CSI-RS的开销。As shown in reference Figure 1e, in the AI/ML-based CSI prediction, the prediction model on the terminal 101 side can predict the CSI at time t2 based on the originally configured CSI-RS, thereby reducing the CSI-RS configured outside the original period at time t2 and saving CSI-RS overhead.
或者,通过重配置或者配置不同周期的CSI-RS进行组合,对原配置周期的CSI-RS进行调整,此时需要进行多次或多套CSI-RS配置。Alternatively, the CSI-RS of the original configuration period is adjusted by reconfiguring or configuring CSI-RS of different periods for combination. In this case, multiple times or multiple sets of CSI-RS configurations are required.
本公开实施例中,参考图1f所示,一个CSI report可能会对应有多个CSI-RS,但表达其中一个CSI-RS 对应时刻的信道状态。更具体地,对于相关联的CSI report和CSI-RS,需要通过CSI参考资源(CSI Reference Resource)确定某个CSI report对应的CSI-RS。In the embodiment of the present disclosure, as shown in FIG. 1f, a CSI report may correspond to multiple CSI-RS, but the expression of one of the CSI-RS More specifically, for the associated CSI report and CSI-RS, it is necessary to determine the CSI-RS corresponding to a certain CSI report through a CSI reference resource (CSI Reference Resource).
CSI report内容的获得需要使用CSI参考资源之前的CSI资源(虚线框)计算得到。当高层参数“timeRestrictionForChannelMeasurements”被配置为“notConfigured”,终端101可以自主地在虚线框中的CSI资源中选取一个。当高层参数“timeRestrictionForChannelMeasurements”被配置为“Configured”,终端101可以选择虚线框中最后一个CSI资源计算CSI report。The CSI report content needs to be calculated using the CSI resource (dashed box) before the CSI reference resource. When the high-level parameter "timeRestrictionForChannelMeasurements" is configured as "notConfigured", the terminal 101 can autonomously select one of the CSI resources in the dashed box. When the high-level parameter "timeRestrictionForChannelMeasurements" is configured as "Configured", the terminal 101 can select the last CSI resource in the dashed box to calculate the CSI report.
本公开实施例中,对于终端101侧的预测模型而言,在模型训练阶段可以使用短周期的CSI-RS进行数据收集,在模型部署阶段可以使用长周期的CSI-RS配置CSI预测。此时需要网络设备102分别进行配置,即配置短周期的CSI-RS,再重新为终端101配置长周期的CSI-RS或激活已配置的长周期的CSI-RS。In the disclosed embodiment, for the prediction model on the terminal 101 side, a short-period CSI-RS can be used for data collection in the model training phase, and a long-period CSI-RS can be used to configure CSI prediction in the model deployment phase. In this case, the network device 102 needs to be configured separately, that is, configure a short-period CSI-RS, and then reconfigure a long-period CSI-RS for the terminal 101 or activate the configured long-period CSI-RS.
其中,在通过无线资源控制(Radio Resource Control,RRC)进行重配置时,所需时延较长,并可能需要配置至少两个新的CSI-RS,对于多用户多入多出技术(Multi-UserMultiple-InputMultiple-Output,MU-MIMO)而言,若每个使用CSI预测的终端101都进行CSI-RS的重配置,开销过大。Among them, when reconfiguring through Radio Resource Control (RRC), the required delay is relatively long, and at least two new CSI-RS may need to be configured. For Multi-User Multiple-Input Multiple-Output (MU-MIMO) technology, if each terminal 101 using CSI prediction reconfigures the CSI-RS, the overhead will be too large.
或者,可以使用RRC进行重配置将原短周期的CSI-RS修改为长周期,需要较长的反应时间,并仍可能需要配置新的CSI-RS。当模型需要再次重新进行数据收集时,由长周期切换回原先短周期时域特性的CSI-RS需要较长的反应时间,影响系统性能。Alternatively, RRC can be used for reconfiguration to change the original short-period CSI-RS to a long-period one, which requires a longer response time and may still require the configuration of a new CSI-RS. When the model needs to collect data again, switching from a long period back to the original short-period CSI-RS time domain characteristics requires a longer response time, affecting system performance.
或者,网络设备102激活已配置的长周期的CSI-RS,并对当前短周期的CSI-RS进行去激活或释放(release),此时仍可能需要配置新的CSI-RS。对于MU-MIMO而言,若每个使用CSI预测的终端101都需要进行如上重配置,即每个短周期CSI-RS都进行至少两个长周期CSI-RS的候选配置,由于一个终端101最多可以被配置64个CSI-RS,若需要在终端101侧实现多种不同时域特性的预测,很可能造成允许被配置的CSI-RS数量不足。Alternatively, the network device 102 activates the configured long-period CSI-RS and deactivates or releases the current short-period CSI-RS. At this time, it may still be necessary to configure a new CSI-RS. For MU-MIMO, if each terminal 101 using CSI prediction needs to be reconfigured as above, that is, each short-period CSI-RS is configured with at least two long-period CSI-RS candidates, since a terminal 101 can be configured with a maximum of 64 CSI-RSs, if it is necessary to implement predictions of multiple different time domain characteristics on the terminal 101 side, it is likely that the number of CSI-RSs allowed to be configured is insufficient.
本公开实施例中,提供一种针对UE侧时域CSI预测降低CSI-RS开销的配置增强方法。In an embodiment of the present disclosure, a configuration enhancement method for reducing CSI-RS overhead for time domain CSI prediction at the UE side is provided.
图2a是根据本公开实施例示出的一种通信方法的交互示意图。如图2a所示,本公开实施例涉及一种通信方法,上述方法包括:FIG2a is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2a, an embodiment of the present disclosure relates to a communication method, and the method includes:
步骤S2101,网络设备102向终端101发送第一信息。Step S2101, the network device 102 sends first information to the terminal 101.
在一些实施例中,第一信息用于指示第一周期与第二周期之间的调整信息,其中,第一周期或第二周期为针对终端被配置的信道状态信息CSI资源的周期,第二周期与第一周期不同。In some embodiments, the first information is used to indicate adjustment information between a first period and a second period, wherein the first period or the second period is a period of channel state information CSI resources configured for the terminal, and the second period is different from the first period.
可选地,第二周期大于第一周期,即第一周期对应短周期(short periodicity),第二周期对应长周期(long periodicity)。Optionally, the second period is greater than the first period, that is, the first period corresponds to a short period (short periodicity) and the second period corresponds to a long period (long periodicity).
可选地,第一周期为网络设备为终端配置的周期,第二周期为终端根据调整信息对第一周期调整之后的周期。Optionally, the first period is a period configured by the network device for the terminal, and the second period is a period after the terminal adjusts the first period according to the adjustment information.
可选地,第一信息可以是指示信息或者配置信息。Optionally, the first information may be indication information or configuration information.
在一些实施例中,调整信息包括以下至少一项:In some embodiments, the adjustment information includes at least one of the following:
调整倍数;Adjust multiples;
在第一数量的CSI资源中被保留或被省略的CSI资源。CSI resources that are reserved or omitted in the first number of CSI resources.
可选地,若第一信息指示调整倍数为n,可以根据第一周期和第一信息确定第二周期,如第二周期为n倍的第一周期。Optionally, if the first information indicates that the adjustment multiple is n, the second period may be determined according to the first period and the first information, such as the second period being n times the first period.
可选地,被省略的CSI资源还可以称为被打孔的CSI资源。例如,若第一周期需切换为第二周期,第一信息可以指示被打孔的某一个或多个第一周期的CSI资源,则将该一个或多个第一周期的CSI资源打孔,切换为第二周期的CSI资源。其中,被打孔或被省略的CSI资源是终端101可以不用接收的CSI资源,和/或网络设备102可以不用发送的CSI资源。被保留的CSI资源终端101仍需接收,网络设备102仍需发送。Optionally, the omitted CSI resources may also be referred to as punctured CSI resources. For example, if the first period needs to be switched to the second period, the first information may indicate one or more punctured CSI resources of the first period, and the one or more CSI resources of the first period are punctured and switched to CSI resources of the second period. Among them, the punctured or omitted CSI resources are CSI resources that the terminal 101 may not receive, and/or CSI resources that the network device 102 may not send. The terminal 101 still needs to receive the reserved CSI resources, and the network device 102 still needs to send.
可选地,第一数量与调整倍数有关。例如,第一数量是根据调整倍数确定的。Optionally, the first quantity is related to the adjustment multiple. For example, the first quantity is determined according to the adjustment multiple.
在一示例中,第一数量K满足:In one example, the first number K satisfies:
K=(n-1),其中,n为调整倍数。K = (n - 1), where n is the adjustment multiple.
在一些实施例中,CSI资源包括以下至少一项:In some embodiments, the CSI resource includes at least one of the following:
信道状态信息参考信号CSI-RS资源(CSI-RS resource);Channel state information reference signal CSI-RS resource (CSI-RS resource);
信道状态信息干扰测量CSI-IM资源(CSI-IM resource)。Channel state information interference measurement CSI-IM resource (CSI-IM resource).
可选地,本公开实施例的描述以CSI-RS资源为例进行描述。Optionally, the description of the embodiments of the present disclosure is described using CSI-RS resources as an example.
可选地,CSI-RS资源可以包括非零功率的CSI-RS资源(NZP CSI-RS resource)和零功率的CSI-RS资源(ZP CSI-RS resource)。 Optionally, the CSI-RS resources may include non-zero power CSI-RS resources (NZP CSI-RS resources) and zero power CSI-RS resources (ZP CSI-RS resources).
可选地,参考图2c~图2d所示,以基于人工智能AI或机器学习ML预测的预测CSI作为被省略的CSI资源对应的CSI。可以理解的,终端101不会基于测量得到被省略的CSI资源对应的测量CSI,而可以采用基于AI或ML的模型预测得到其对应的CSI。Optionally, referring to Figures 2c to 2d, the predicted CSI based on artificial intelligence AI or machine learning ML is used as the CSI corresponding to the omitted CSI resource. It can be understood that the terminal 101 will not obtain the measured CSI corresponding to the omitted CSI resource based on measurement, but can use the AI or ML-based model prediction to obtain its corresponding CSI.
在一些实施例中,第一信息包括第一字段和第二字段;In some embodiments, the first information includes a first field and a second field;
其中,第一字段用于指示调整倍数,第二字段用于指示第一数量的CSI资源中被保留或被省略的CSI资源。The first field is used to indicate the adjustment multiple, and the second field is used to indicate the CSI resources that are reserved or omitted in the first number of CSI resources.
在一示例中,第一信息可以采用如下prediction字段:
In an example, the first information may use the following prediction field:
其中,第一字段为multiplePeriodicity,用于指示调整倍数,最大倍数的最大值为n且为整数。The first field is multiplePeriodicity, which is used to indicate the adjustment multiple, and the maximum value of the maximum multiple is n and is an integer.
第二字段为bitmap,指示比特位图的最大长度为(n-1),其中,比特位图中的比特的默认值可以均是0。The second field is bitmap, indicating that the maximum length of the bitmap is (n-1), wherein the default values of the bits in the bitmap may all be 0.
在一些实施例中,第二字段占用第一数量个比特,第一数量个比特分别与不同的CSI资源对应,通过第一数量个比特中每个比特的值指示对应的CSI资源是否被保留或被省略。其中,第一数量K=(n-1)。In some embodiments, the second field occupies a first number of bits, the first number of bits respectively correspond to different CSI resources, and the value of each bit in the first number of bits indicates whether the corresponding CSI resource is reserved or omitted. The first number K=(n-1).
该实施例中,比特位图中每个比特分别对应一个CSI资源,从而通过该比特的值可以指示对应的CSI资源是否被省略。In this embodiment, each bit in the bitmap corresponds to a CSI resource, so that the value of the bit can indicate whether the corresponding CSI resource is omitted.
可选地,在任一比特的值为1时,表示保留原配置的CSI资源;例如需从第一周期切换为第二周期时,某一比特为1,表示保留该比特对应的第一周期的CSI资源。在任一比特的值为0时,表示原配置的CSI资源被打孔;例如需从第一周期切换为第二周期时,某一比特为0,表示该比特对应的第一周期的CSI资源被打孔。Optionally, when the value of any bit is 1, it indicates that the originally configured CSI resources are retained; for example, when it is necessary to switch from the first period to the second period, a certain bit is 1, indicating that the CSI resources of the first period corresponding to the bit are retained. When the value of any bit is 0, it indicates that the originally configured CSI resources are punctured; for example, when it is necessary to switch from the first period to the second period, a certain bit is 0, indicating that the CSI resources of the first period corresponding to the bit are punctured.
在一些实施例中,第一信息占用第一信息域和第二信息域;In some embodiments, the first information occupies a first information field and a second information field;
第一信息域包括第一字段占用的比特和第一保留(reserve)比特,第二信息域包括第二字段占用的比特和第二保留比特。The first information field includes bits occupied by the first field and a first reserved bit, and the second information field includes bits occupied by the second field and a second reserved bit.
可以理解的,此处第一保留比特和第二保留比特为了区分不同信息域中的保留比特,而非限定保留比特的数量或位置。例如,第一信息域中的第一保留比特可配置有多个,第二信息域中的第二保留比特也可以配置多个。It can be understood that the first reserved bit and the second reserved bit are used to distinguish the reserved bits in different information fields, rather than to limit the number or position of the reserved bits. For example, the first reserved bit in the first information field can be configured with multiple bits, and the second reserved bit in the second information field can also be configured with multiple bits.
在一些实施例中,步骤S2101可以包括如下步骤S2101A或者S2101B,其中:In some embodiments, step S2101 may include the following steps S2101A or S2101B, wherein:
步骤S2101A,网络设备102向终端101发送RRC消息,RRC消息包括第一信息。Step S2101A, the network device 102 sends an RRC message to the terminal 101, and the RRC message includes first information.
该实施例中,网络设备102通过RRC消息发送该第一信息。In this embodiment, the network device 102 sends the first information via an RRC message.
该实施例中,网络设备102发送配置信息,在配置信息中包含该第一信息。例如,网络设备102在CSI-RS配置(CSI-RS configuration)中新增第一信息。In this embodiment, the network device 102 sends configuration information, and the configuration information includes the first information. For example, the network device 102 adds the first information in the CSI-RS configuration.
在一示例中,第一信息包含在CSI-RS配置中,例如参考如下NZP-CSI-RS-Resource的信息元素(Information Element,IE):In one example, the first information is included in the CSI-RS configuration, for example, referring to the following information element (IE) of NZP-CSI-RS-Resource:
NZP-CSI-RS-Resource Information Element
NZP-CSI-RS-Resource Information Element
其中,“OPTIONAL,--Need R”表示当对应字段不存在时,终端101需要释放该字段的值。Among them, "OPTIONAL,--Need R" means that when the corresponding field does not exist, terminal 101 needs to release the value of the field.
可选地,针对每个CSI-RS资源可新增对应的第一信息。Optionally, corresponding first information may be added for each CSI-RS resource.
可选地,被打孔的CSI-RS对应的时频资源可以用于传输其他内容,从而提升时域资源的利用率。Optionally, the time-frequency resources corresponding to the punctured CSI-RS can be used to transmit other content, thereby improving the utilization of time domain resources.
可选地,还可以配置CSI report、及CSI report与CSI-RS资源的关联关系。Optionally, you can also configure the CSI report and the association between the CSI report and CSI-RS resources.
该实施例中,通过在CSI-RS配置中增加第一信息对应的字段,可以将原配置的第一周期根据prediction字段扩展为第二周期,并确定第二周期对应的CSI-RS图样。以便于终端101可以获知在何位置也即在何周期不需要进行对应CSI-RS的接收,以及基于CSI-RS的传统CSI计算,从而可以将所有计算资源用于AI模型对这些位置的CSI预测。In this embodiment, by adding a field corresponding to the first information in the CSI-RS configuration, the first period of the original configuration can be extended to a second period according to the prediction field, and the CSI-RS pattern corresponding to the second period can be determined. This allows the terminal 101 to know at which position, that is, at which period, the corresponding CSI-RS reception is not required, as well as the traditional CSI calculation based on the CSI-RS, so that all computing resources can be used for the AI model to predict the CSI at these positions.
步骤S2101B,网络设备102向终端101发送MAC CE,MAC CE包括第一信息。Step S2101B, the network device 102 sends a MAC CE to the terminal 101, and the MAC CE includes the first information.
可选地,在CSI资源为半静态的CSI资源时,可采用该步骤S2101B。Optionally, when the CSI resource is a semi-static CSI resource, step S2101B may be adopted.
该实施例中,网络设备102在发送MAC CE之前,可通过RRC消息配置了半静态的CSI资源,例如配置了第一周期的CSI-RS。MAC CE用于激活或去激活半静态的CSI资源配置。其中,在采用步骤S2101B的示例中该RRC消息中未增加第一信息。In this embodiment, before sending MAC CE, the network device 102 may configure semi-static CSI resources through RRC messages, for example, configuring CSI-RS of the first period. MAC CE is used to activate or deactivate semi-static CSI resource configuration. In the example of step S2101B, the first information is not added to the RRC message.
可选地,网络设备102可在MAC CE中新增上述第一信息,例如在SP CSI-RS/CSI-IM Resource Set Activation/Deactivation MAC CE中增加第一信息对应的字段。Optionally, the network device 102 may add the above-mentioned first information in the MAC CE, for example, by adding a field corresponding to the first information in the SP CSI-RS/CSI-IM Resource Set Activation/Deactivation MAC CE.
在一示例中,参考图2e所示的MAC CE结构,在MAC CE信令中增加第一信息域和第二信息域,第一信息域用于指示第一字段multiplePeriodicity,第二信息域用于指示第二字段bitmap,两域中除第一字段或第二字段外的比特可采用保留比特占位。图中Oct表示字节(octet)。In one example, referring to the MAC CE structure shown in FIG2e, a first information field and a second information field are added to the MAC CE signaling, the first information field is used to indicate the first field multiplePeriodicity, and the second information field is used to indicate the second field bitmap. The bits in the two fields except the first field or the second field can be reserved. In the figure, Oct represents an octet.
可选地,第一信息域可占用Oct N+5比特,即第一字段占用N比特,保留比特为5比特,并可以根据实际应用情况调整。第二信息域可占用Oct N+6比特,即第二字段占用N比特,保留比特为6比特,可以根据实际应用情况调整。其中,保留比特可设置为0。Optionally, the first information field may occupy Oct N+5 bits, that is, the first field occupies N bits, and the reserved bits are 5 bits, which can be adjusted according to actual application conditions. The second information field may occupy Oct N+6 bits, that is, the second field occupies N bits, and the reserved bits are 6 bits, which can be adjusted according to actual application conditions. Among them, the reserved bits can be set to 0.
可选地,仍可参照前述实施例的描述,例如第一字段所指示的最大周期倍数仍为n,在该示意图中n=1112=710;其中1112表示二进制,710表示十进制。再例如第二字段所指示的比特位图的最大长度为n-1,该示意图中n-1=6。Alternatively, the description of the aforementioned embodiment may still be referred to, for example, the maximum period multiple indicated by the first field is still n, and in the schematic diagram n=111 2 =7 10 ; wherein 111 2 represents binary, and 7 10 represents decimal. For another example, the maximum length of the bitmap indicated by the second field is n-1, and in the schematic diagram n-1=6.
该实施例中,通过在MAC CE中新增第一信息也可以实现在较短的时间内,将第一周期扩展为第二周期,以实现降低CSI开销的效果。在一些实现中,相较于步骤S2101A的方式,步骤S2101B的方式中被打孔的CSI资源可能不用于传输其他内容,步骤S2101A的方式比步骤S2101B的方式在提升时域资源利用率方面效果更好。In this embodiment, by adding the first information in the MAC CE, the first cycle can be extended to the second cycle in a shorter time, so as to reduce the CSI overhead. In some implementations, compared with the method of step S2101A, the punctured CSI resources in the method of step S2101B may not be used to transmit other content, and the method of step S2101A is better than the method of step S2101B in improving the utilization rate of time domain resources.
在一些实施例中,终端101接收该第一信息。In some embodiments, terminal 101 receives the first information.
步骤S2102,网络设备102向终端101发送第二信息。Step S2102 , the network device 102 sends second information to the terminal 101 .
在一些实施例中,第二信息用于指示执行第一周期与第二周期之间的切换。In some embodiments, the second information is used to instruct to perform switching between the first cycle and the second cycle.
可选地,第二信息为激活第一周期与第二周期之间切换或调整的信令。Optionally, the second information is a signaling for activating switching or adjustment between the first cycle and the second cycle.
在一些实施例中,第二信息可以复用与AI模型的LCM相关的信令。In some embodiments, the second information may multiplex signaling related to the LCM of the AI model.
在一些实施例中,第二信息包括以下至少一项:In some embodiments, the second information includes at least one of the following:
用于指示进行基于AI或ML模型部署的信息;Information indicating the deployment of AI or ML models;
用于指示切换回第一周期的信息。Information for indicating switching back to the first cycle.
可选地,在需由第一周期到第二周期的切换时,网络设备102可通过发送用于指示进行基于AI或ML模型部署的信息,指示执行该切换。Optionally, when switching from the first cycle to the second cycle is required, the network device 102 may instruct execution of the switching by sending information for instructing deployment based on an AI or ML model.
可选地,在需由第二周期到第一周期的切换时,网络设备102可通过发送用于指示切换回第一周期的信息,指示执行该切换。可以理解的,切换回第一周期用于代表切换回切换之前的原配置的周期。Optionally, when switching from the second cycle to the first cycle is required, the network device 102 may instruct to perform the switching by sending information for instructing to switch back to the first cycle. It can be understood that switching back to the first cycle is used to represent switching back to the original configured cycle before the switching.
在一些实施例中,第二信息的生效时间为以下至少一项:In some embodiments, the effective time of the second information is at least one of the following:
第二信息所在时域单元之后的第一个CSI资源所在的时域单元;A time domain unit where the first CSI resource after the time domain unit where the second information is located is located;
第一反馈信息所在的时域单元之后的第一个CSI资源所在的时域单元,第一反馈信息为终端针对第二信息的混合自动重传HAQR确认信息(ACK);a time domain unit where a first CSI resource after the time domain unit where the first feedback information is located, where the first feedback information is hybrid automatic repeat transmission HAQR acknowledgment information (ACK) of the terminal for the second information;
其中,第一个CSI资源所在的时域单元为切换后的第一周期或第二周期的起始时间。The time domain unit where the first CSI resource is located is the start time of the first cycle or the second cycle after switching.
可选地,终端中基于AI或ML的CSI预测模型的输入包括第一个CSI资源。Optionally, the input of the AI or ML-based CSI prediction model in the terminal includes the first CSI resource.
在一示例中,参考图2c所示,第一信息的第一字段指示调整倍数为3,第二字段指示比特位 图为00,则该第一信息指示第一周期与第二周期之间的调整信息包括:第二周期为第一周期的2倍,其中在第二信息生效之后有2个第一周期的CSI-RS被打孔。In one example, referring to FIG. 2c, the first field of the first information indicates that the adjustment multiple is 3, and the second field indicates the bit position The figure is 00, then the first information indicates that the adjustment information between the first period and the second period includes: the second period is twice the first period, wherein two CSI-RS of the first period are punctured after the second information takes effect.
该示例中,在网络设备102发送第1个CSI-RS后,若网络设备102与终端101基于切换信令理解一致,如网络设备102发送第二信息或者终端101收到第三信息,指示需要从第一周期切换第二周期也即从短周期切换为长周期,根据第二信息或第三信息所在的时域单元之后的第一个CSI-RS即图示的第2个CSI-RS,在第2个CSI-RS开始采用切换后的周期,且该第2个CSI-RS为新周期即切换后周期的起始时间,该第2个CSI-RS还可以作为AI模型的输入。In this example, after the network device 102 sends the first CSI-RS, if the network device 102 and the terminal 101 have a consistent understanding based on the switching signaling, such as the network device 102 sends the second information or the terminal 101 receives the third information, indicating the need to switch from the first period to the second period, that is, from the short period to the long period, according to the first CSI-RS after the time domain unit where the second information or the third information is located, that is, the second CSI-RS shown in the figure, the switched period is adopted starting from the second CSI-RS, and the second CSI-RS is the starting time of the new period, that is, the period after the switch, and the second CSI-RS can also be used as the input of the AI model.
该示例中,从第二周期切换回第一周期时,仍可参照图2c所示,从收到相应切换信令之后的第一个CSI-RS开始切换后的周期。In this example, when switching back from the second period to the first period, the period after switching can still be started from the first CSI-RS after receiving the corresponding switching signaling, as shown in FIG. 2c.
该实施例中,切换信令第二信息的有效性设置可以在保证图样稳定性的同时,达到最佳的CSI-RS开销降低效果。In this embodiment, the validity setting of the second information of the switching signaling can achieve the best CSI-RS overhead reduction effect while ensuring the pattern stability.
在另一示例中,参考图2d所示,第一信息的第一字段指示调整倍数为4,第二字段指示比特位图为001,则该第一信息指示第一周期与第二周期之间的调整信息包括:第二周期为第一周期的4倍,其中在第二信息生效之后有2个第一周期的CSI-RS被打孔,1个第一周期的CSI-RS被保留。In another example, as shown in reference Figure 2d, the first field of the first information indicates that the adjustment multiple is 4, and the second field indicates that the bit map is 001. The first information indicates that the adjustment information between the first period and the second period includes: the second period is 4 times the first period, wherein after the second information takes effect, 2 CSI-RS of the first period are punctured and 1 CSI-RS of the first period is retained.
在一些实施例中,终端101接收该第二信息。In some embodiments, terminal 101 receives the second information.
步骤S2103,终端101基于AI/ML模型预测CSI。Step S2103: Terminal 101 predicts CSI based on the AI/ML model.
在一些实施例中,结合前述实施例的描述,每个CSI都可能对应配置了一个或多个CSI-RS,在使用基于AI的CSI预测模型的场景中,终端101预测得出某个CSI,可以省下该CSI对应的一个或多个CSI-RS的开销,从而提升时频资源的利用率;同时,UE也无需对这部分CSI-RS进行接收,进而达到终端节能的效果。In some embodiments, combined with the description of the foregoing embodiments, each CSI may be configured with one or more CSI-RS. In the scenario of using the AI-based CSI prediction model, the terminal 101 predicts a certain CSI, which can save the overhead of one or more CSI-RS corresponding to the CSI, thereby improving the utilization rate of time-frequency resources; at the same time, the UE does not need to receive this part of the CSI-RS, thereby achieving the effect of terminal energy saving.
例如,被省略的CSI资源,终端101可根据基于AI或ML模型进行预测得到对应的预测CSI,从而终端101不用测量该部分被省略的CSI资源。For example, for omitted CSI resources, the terminal 101 can obtain the corresponding predicted CSI based on the prediction based on the AI or ML model, so that the terminal 101 does not need to measure the omitted CSI resources.
在一些实施例中,网络设备102在第一周期的RRC配置或MAC CE中增加第一信息,可以使终端101在模型准备阶段利用原配置的第一周期收集足够多的数据,以保证模型训练效果;在模型部署阶段利用新增的第一信息将第一周期调整为第二周期,减少终端进行传统CSI-RS的测量计算处理的过程,可有效节能。在该过程中,网络设备102无需增加CSI-RS的重配置或额外开销,在利用RRC中第一信息进行打孔后还可以提升该部分CSI资源的时频资源利用率,终端101也无需接收被打孔部分的CSI资源,进一步实现终端的节能。In some embodiments, the network device 102 adds the first information in the RRC configuration or MAC CE of the first period, so that the terminal 101 can collect enough data using the first period of the original configuration in the model preparation stage to ensure the model training effect; in the model deployment stage, the first period is adjusted to the second period using the newly added first information, reducing the process of the terminal performing traditional CSI-RS measurement and calculation processing, which can effectively save energy. In this process, the network device 102 does not need to increase the reconfiguration or additional overhead of the CSI-RS. After using the first information in the RRC for puncturing, the time-frequency resource utilization rate of this part of the CSI resources can also be improved. The terminal 101 does not need to receive the CSI resources of the punctured part, which further realizes the energy saving of the terminal.

为便于理解本公开实施例,以下列举一些具体示例:To facilitate understanding of the embodiments of the present disclosure, some specific examples are listed below:
示例一:Example 1:
采用方式一,即对CSI-RS在RRC配置中进行增强。Method 1 is adopted, that is, CSI-RS is enhanced in RRC configuration.
为了不增加额外的CSI-RS开销,考虑在RRC配置消息CSI-RS configuration中新增可切换周期的配置,设计长短周期之间的倍数关系,并考虑通过位图指示需要被打孔的CSI-RS,如下图:In order not to increase the extra CSI-RS overhead, consider adding a switchable period configuration in the RRC configuration message CSI-RS configuration, design the multiple relationship between the long and short periods, and consider indicating the CSI-RS that needs to be punctured through a bitmap, as shown in the following figure:
NZP-CSI-RS-Resource Information Element
NZP-CSI-RS-Resource Information Element
其中,整个新增的prediction字段针对每个CSI-RS resource而言。Among them, the entire newly added prediction field is for each CSI-RS resource.
可选地,附加的字段说明为“OPTIONAL,--Need R”,表示当此字段不存在时,UE需要释放此字段的值。Optionally, the additional field description is "OPTIONAL,--Need R", indicating that when this field does not exist, the UE needs to release the value of this field.
可选地,MultiplePeriodicity表示长短周期之间的倍数关系,需为整数,最大周期倍数为n;对应于前述实施例的第一字段。 Optionally, MultiplePeriodicity represents the multiple relationship between long and short periods, and needs to be an integer, with a maximum period multiple of n; corresponding to the first field of the aforementioned embodiment.
可选地,Bitmap表示使用何种位图对现有CSI-RS进行打孔,对应于前述实施例的第一字段。其中:Optionally, Bitmap indicates which bitmap is used to puncture the existing CSI-RS, corresponding to the first field of the aforementioned embodiment.
0表示原有的CSI-RS被打孔,且对应的CSI被预测值代替;0 means that the original CSI-RS is punctured and the corresponding CSI is replaced by the predicted value;
1表示保留原有的CSI-RS;1 means retaining the original CSI-RS;
位图的最大长度为最大周期倍数n-1,默认值为全零。The maximum length of the bitmap is the maximum period multiple n-1, and the default value is all zeros.
上述内容配合可以在现有短周期的CSI-RS上确定一个新的长周期CSI-RS图样。The above contents can be combined to determine a new long-period CSI-RS pattern on the existing short-period CSI-RS.
可选地,短周期对应前述实施例中的第一周期,即RRC配置消息中为CSI-RS配置的原周期;长周期对应前述实施例中的第二周期,即根据RRC配置消息中新增字段指示的调整信息所确定的周期。Optionally, the short cycle corresponds to the first cycle in the aforementioned embodiment, that is, the original cycle configured for CSI-RS in the RRC configuration message; the long cycle corresponds to the second cycle in the aforementioned embodiment, that is, the cycle determined according to the adjustment information indicated by the newly added field in the RRC configuration message.
可选地,新增的prediction字段对应于前述实施例的第一信息。Optionally, the newly added prediction field corresponds to the first information in the aforementioned embodiment.
可选地,通过上述对CSI-RS配置的增强,UE可以知道在哪些位置不需要进行对应CSI-RS的接收,以及基于CSI-RS的传统CSI计算,从而可以将所有计算资源用于AI模型对这些位置的CSI预测。同时,被打孔的CSI-RS对应的时频资源可以用于传输其他内容。Optionally, through the above enhancements to CSI-RS configuration, the UE can know where the corresponding CSI-RS reception is not needed, as well as the traditional CSI calculation based on CSI-RS, so that all computing resources can be used for the AI model to predict the CSI at these locations. At the same time, the time-frequency resources corresponding to the punctured CSI-RS can be used to transmit other content.
可选地,对于对应的CSI report配置及其与CSI-RS的关联关系,在本示例中无需改变。Optionally, the corresponding CSI report configuration and its association with CSI-RS do not need to be changed in this example.
示例二:Example 2:
可能的长短周期切换的激活信令可以复用与AI模型的LCM相关的如下信令:The activation signaling for possible long and short cycle switching can reuse the following signaling related to the LCM of the AI model:
进行短周期到长周期的切换:UE反馈数据收集完成或gNB指示开始进行模型部署等;Switching from short cycle to long cycle: UE feedback data collection is completed or gNB instructs to start model deployment, etc.
进行长周期到短周期的切换:UE指示需要重新收集数据或gNB指示需要切换回原有模式等;Switching from a long cycle to a short cycle: the UE indicates that data needs to be collected again or the gNB indicates that it needs to switch back to the original mode, etc.
可选地,长短周期切换的激活信令应该在下一个CSI-RS的时隙开始生效,即:若在第一个CSI-RS发送后,UE和gNB达成对切换信令的一致,则第2个CSI-RS开始对变化的周期生效,且第2个CSI-RS作为新周期的开始被保留,并可以被当作AI模型的输入。上述激活信令的有效设置可以在保证一定的图样稳定性的同时,达到最佳的CSI-RS开销降低效果。Optionally, the activation signaling for the long-short cycle switching should take effect at the next CSI-RS time slot, that is, if the UE and gNB reach an agreement on the switching signaling after the first CSI-RS is sent, the second CSI-RS will take effect on the changed period, and the second CSI-RS will be retained as the beginning of the new period and can be used as the input of the AI model. The effective setting of the above activation signaling can achieve the best CSI-RS overhead reduction effect while ensuring a certain pattern stability.
可选地,流程示意图及配置示意图参考图2c~图2d,可见,当空口两侧的UE和gNB达成对切换信令的一致后,新的周期图样从最近的CSI-RS开始生效,且此最近的CSI-RS被保留,并被当作AI模型的输入。Optionally, the flow chart and configuration chart refer to Figure 2c to Figure 2d. It can be seen that when the UE and gNB on both sides of the air interface reach an agreement on the switching signaling, the new periodic pattern takes effect from the most recent CSI-RS, and this most recent CSI-RS is retained and used as the input of the AI model.
可选地,示例二可以在示例一的基础上执行。Optionally, Example 2 can be performed based on Example 1.
示例三:Example 3:
采用方式二,即对半静态的CSI-RS,在MAC CE的配置中进行增强。The second method is to enhance the semi-static CSI-RS in the configuration of MAC CE.
对于半静态的CSI-RS,考虑对“SP CSI-RS/CSI-IM Resource Set Activation/Deactivation MAC CE”进行增强,参考图2e所示。For semi-static CSI-RS, consider enhancing the “SP CSI-RS/CSI-IM Resource Set Activation/Deactivation MAC CE”, as shown in Figure 2e.
可选地,MultiplePeriodicity:表示长短周期之间的倍数关系,默认为全零;Optionally, MultiplePeriodicity: indicates the multiple relationship between long and short periods, and defaults to all zeros;
在此示意图中,类比上面的RRC增强配置,最大周期倍数为1112=710=n;此域的真实长度可以通过占用Oct N+5的保留比特,根据实际情况进行修正。In this diagram, analogous to the above RRC enhanced configuration, the maximum period multiple is 111 2 =7 10 =n; the actual length of this field can be modified according to the actual situation by occupying the reserved bits of Oct N+5.
可选地,Bitmap:表示使用何种位图对现有CSI-RS进行打孔,其中:Optionally, Bitmap: indicates which bitmap is used to puncture the existing CSI-RS, where:
0表示原有的CSI-RS被打孔,且对应的CSI被预测值代替;0 means that the original CSI-RS is punctured and the corresponding CSI is replaced by the predicted value;
1表示保留原有的CSI-RS;1 means retaining the original CSI-RS;
位图的最大长度为最大周期倍数n-1,默认值为全零;The maximum length of the bitmap is the maximum period multiple n-1, and the default value is all zeros;
本示意图中,n-1=6;In this schematic diagram, n-1=6;
此域的真实长度可以通过占用Oct N+6的保留比特,根据实际情况进行修正。The actual length of this field can be modified according to actual conditions by occupying the reserved bits of Oct N+6.
可选地,图中R表示保留比特,设为0。Optionally, R in the figure represents a reserved bit, which is set to 0.
本公开实施例中,能够支持UE侧时域CSI预测的数据收集和模型部署,能够支持上述两阶段的灵活切换,能够降低模型部署阶段的CSI-RS开销,不需要增加额外的CSI-RS配置及开销,可以提升时频资源的利用率,此外终端无需接收被打孔部分的CSI-RS资源,从而达到节能的效果。In the disclosed embodiments, it is possible to support data collection and model deployment for time-domain CSI prediction on the UE side, support flexible switching between the above two stages, reduce the CSI-RS overhead in the model deployment stage, and does not require additional CSI-RS configuration and overhead. The utilization rate of time-frequency resources can be improved. In addition, the terminal does not need to receive the CSI-RS resources of the perforated part, thereby achieving energy saving.
本公开实施例中,针对UE侧时域CSI预测降低CSI-RS开销的配置增强方案。通过对CSI-RS配置的增强以及半静态CSI-RS资源的MAC CE激活信令的增强,在保证UE侧时域CSI预测模型的数据收集与模型部署正常进行及灵活切换的同时,降低CSI-RS的开销,并可以达到UE侧节能的效果。In the disclosed embodiment, a configuration enhancement scheme is provided for reducing CSI-RS overhead for time-domain CSI prediction on the UE side. By enhancing the CSI-RS configuration and the MAC CE activation signaling of the semi-static CSI-RS resources, the CSI-RS overhead is reduced while ensuring the normal data collection and model deployment of the time-domain CSI prediction model on the UE side and flexible switching, and the energy saving effect on the UE side can be achieved.
