[0021] The present invention discloses detailed embodiments and implementations of the claimed subject matter. However, it should be understood that the embodiments and implementations disclosed by the present invention are merely illustrations of the claimed subject matter, and the claimed subject matter can be implemented in various forms. However, the present invention can be implemented in many different forms and should not be interpreted as being limited to the exemplary embodiments and implementations described in the present invention. On the contrary, these exemplary embodiments and implementations are provided so that the description of the present invention is thorough and complete, and the scope of the present invention can be fully conveyed to those skilled in the art. In the following description, well-known features and technical details may be omitted to avoid unnecessarily obscuring the embodiments and implementations of the present invention.

[0022] Overview

[0023] The implementation of the content of the present invention involves various technologies, methods, schemes and / or solutions, which are related to measurement resources and report configurations for device cooperative communication, for example, measurement resources and report configurations of communication devices supporting device cooperation in mobile communication. According to the content of the present invention, multiple possible solutions can be implemented separately or in combination. That is, although these possible solutions may be described separately, two or more possible solutions can be implemented in some combination.

[0024] Figure 1 An example scenario 100 for implementing device cooperation in a mobile communication network according to an implementation of the present invention is shown. A personal area network (PAN) can support extended reality (XR)-like services, such as XR glasses used with a mobile phone or customer premises equipment (CPE). A public network can include one or more repeaters and a mobile phone. In some implementations, at least one device can be a cooperative communication device in device cooperative communication to facilitate the enhancement of the transceiver capability (e.g., antenna capability, diversity, rank, or other) of the primary communication device in the mobile communication network.

[0025] Figure 2An example scenario 200 of diversity enhancement based on device collaboration according to an implementation of the present invention is shown. A high-capability device (e.g., a smartphone) can act as a proxy to provide a high-quality data path for a low-capability device (e.g., XR glasses). In this device collaboration scenario, the high-capability device can be a collaborative communication device or a collaborative UE, and the low-capability device can be a master communication device or a master UE. A device control path CTRL can be established between the master UE and the collaborative UE to exchange key information, including channel state information (CSI), relay mode enablement, power control, etc.

[0026] The cooperative UE can communicate with a network node (such as a satellite, base station or network device in a mobile communication network) in a first frequency band f1 and communicate with the master UE in a second frequency band f2. Each frequency band is an interval in the frequency domain. The cooperative UE can perform inter-band frequency conversion to convert the radio frequency (RF) carrier of a signal received from the first frequency band f1 to the second frequency band f2, and vice versa. This device cooperation is applicable to both uplink and downlink transmissions.

[0027] Compared with smartphones, wearable devices are usually weaker in terms of MIMO processing capabilities, number of transmit (Tx) or receive (Rx) antennas, carrier aggregation (CA) capabilities, etc. Figure 2 A collaborative UE (e.g., 4Rx smartphone) is demonstrated to work as an intermediate node with a 2Rx wearable device (with 1 component carrier (CC) capability). The smartphone can act as an advanced amplify and forward (AF) repeater with better Rx beamforming capabilities (i.e., more receive antennas) and purify the signal quality by rejecting interference from unexpected directions and forward the processed signal to the low-capability wearable device.

[0028] Figure 3 An example scenario 300 of rank enhancement based on device collaboration according to the implementation of the present invention is shown. A smartphone and a collaborative device (such as a relay device, another smartphone, indoor CPE or others) collaborate to receive a generated high-rank data signal transmitted from a network node (such as a satellite, base station or network device in a mobile communication network) on the smartphone.

[0029] In this device collaboration scenario, the smartphone can be a master communication device or a master UE, and the above-mentioned collaborative device can be a collaborative communication device or a collaborative UE. The master UE can communicate with the network node in the first frequency band f1 and communicate with the collaborative UE in the second frequency band f2. The collaborative UE, like the master UE, can communicate with the network node in the first frequency band f1 and communicate with the master UE in the second frequency band f2. The collaborative UE can perform inter-band frequency conversion to convert the RF carrier of the signal received from the first frequency band f1 to the second frequency band f2, and vice versa. This device collaboration also applies to uplink and downlink transmissions.

[0030] A device control path CTRL can be established between the master UE and the cooperative UE to exchange key information, including CSI, relay mode activation, power control, etc. The master UE uses its CA capability to simultaneously receive signals from the base station and the cooperative UE in two frequency bands f1 and f2, and jointly processes the received signals as if it has two sets of Rx antennas. The network node transmits signals in frequency band f1 to the terminal device that appears to be equipped with two sets of Rx antennas in a single frequency band, so the rank of the end-to-end MIMO channel can be doubled.

[0031] Figure 4 An example scenario 400 of enhancing the transceiver capability based on device cooperation according to the implementation of the present invention is shown. Figure 4 406) can be placed in the main communication device (in Figure 4 In the figure, it is represented as being near the main UE 404), or placed between the network node 402 (such as a satellite, base station or network device in a mobile communication network) and the main UE 404.

[0032] The master UE 404 may communicate with the network node 402 in the first frequency band f1 and communicate with the cooperative UE 406 in the second frequency band f2. The cooperative UE 406 may communicate with the network node 402 in the first frequency band f1 and communicate with the master UE 404 in the second frequency band f2, just like the master UE 404. The cooperative UE 406 may perform inter-band frequency conversion to convert the RF carrier of the signal received from the first frequency band f1 to the second frequency band f2, and vice versa. This device cooperation also applies to uplink and downlink transmissions.

[0033] In some implementations of device cooperative communication, for uplink transmission, the master UE 404 may transmit signals simultaneously or almost simultaneously on two different time-frequency resources or two different frequency bands f1 and f2.

[0034] In some implementations, the two time-frequency resources (e.g., the first time-frequency resource and the second time-frequency resource) do not overlap with each other. In some implementations, the first time-frequency resource and the second time-frequency resource do not overlap with each other in the frequency domain. In some implementations, the first time-frequency resource and the second time-frequency resource do not overlap with each other in the frequency domain, but overlap with each other in the time domain.

[0035] In certain implementations, the first time-frequency resource and the second time-frequency resource are in two non-overlapping frequency bands, in two non-overlapping component carriers, or in two non-overlapping resource block sets within a component carrier.

[0036] In some implementations, the first frequency band and the second frequency band do not overlap each other. In some implementations, the position of the second frequency band is constantly offset relative to the first frequency band. In some implementations, the first frequency band and the second frequency band are two non-overlapping component carriers.

[0037] In some implementations, the master UE 404 may include multiple physical antennas, and the physical antennas may be shared on two different time-frequency resources or two different frequency bands to reduce the chip area cost of the master UE 404. Please note that the master UE 404 may also use two different groups of antennas to transmit signals on two different time-frequency resources or two different frequency bands, respectively, and the present invention is not limited to any type of implementation.

[0038] In one example, the master UE 404 may have 4 physical antennas (i.e., physical antennas 1 to 4) and may have 4 layers of data (i.e., layers 1 to 4) to transmit. In addition, each layer of data corresponds to an antenna port. In a first configuration, the master UE 404 maps a specific layer to a specific physical antenna. For example, data for layer 1 is transmitted via physical antenna 1, data for layer 2 is transmitted via physical antenna 2, and so on. This may be referred to as a non-coherent mode. In a second configuration, at the master UE 404, at least one specific layer is mapped to at least two physical antennas, and at least one physical antenna does not map at least one layer of the 4 layers of data. For example, data for layer 1 is transmitted via physical antenna 1 and physical antenna 2, data for layer 2 is transmitted via physical antenna 3 and physical antenna 4, and so on. This may be referred to as a partially coherent mode. In a third configuration, each layer of data is mapped to all physical antennas. This is referred to as a fully coherent mode.

[0039] For some detailed explanation of the signal model used, in some implementations, the master UE 404 may generate a 4-layer baseband data signal x 1 , x 2 , ..., x 4 , these are the data signals to be transmitted to the network nodes and can be represented by vectors as:

[0040]

[0041] The master UE 404 can transfer the symbol x 4×1 Divided into two groups of signals and The first signal The second signal is transmitted to the network node 402 via the channel 424 (which can be regarded as a direct path or direct link). The master UE 404 can transmit the first signal to the cooperative UE 406, and then transmit it to the network node 402 through channels 428 and 426 (which can be regarded as an indirect path or indirect link). The first precoder is applied on And in the second signal The second precoder is applied on For example, the master UE 404 may transmit the first signal is mapped to a first set of physical antennas (eg, including two physical antennas) to generate The two superimposed signals are is mapped to a second set of physical antennas (eg, including two physical antennas) to generate Two superimposed signals.

[0042] In addition, the master UE 404 may mix the superimposed signal with a corresponding RF carrier and transmit the resulting RF signal on a corresponding physical antenna group.

[0043] For a direct path, the network node 402 can communicate with the network node 402 through the channel 424 (which can be represented as H 1 ) receives a radio frequency signal from the main UE404.

[0044] For the indirect path, the cooperative UE 406 can communicate via the channel 428 (which can be represented as H 2 ) receives the RF signal from the primary UE 404, the network node 402 may receive the RF signal from the primary UE 404 through the channel 426 (which may be represented as H 3 ) receives a radio frequency signal from the cooperative UE 406. The cooperative UE 406 may relay or forward the received radio frequency signal, perform some necessary processing, such as but not limited to amplification or linear combination, and transmit it to the network node 402. The effect of the signal processing performed on the received signal at the cooperative UE 406 can be expressed as G 2×4 .

[0045] For a non-coherent joint transmission (NCJT) scenario across two virtual panels, where each layer is carried by one panel, if extracted from the RF signal received by the physical antenna of the network node 402, the signal r received by the network node 402 is n×1 It can be expressed as:

[0046]

[0047] For the coherent joint transmission (CJT) scenario across two virtual panels, where each layer is carried by two panels, the degree of freedom of precoder design increases (e.g., from 2x2 to 4x4), and if extracted from the RF signal received by the physical antenna of the network node 402, the signal r received by the network node 402 n×1 It can be expressed as:

[0048]

[0049] In some implementations of device cooperative communication, for downlink transmission, the master UE 404 may receive a radio frequency signal in the first frequency band f1 from the network node 402 through a direct path. The cooperative UE 406 may receive the radio frequency signal in the first frequency band f1 from the network node 402, convert the radio frequency carrier of the radio frequency signal to the second frequency band f2, and then transmit the converted radio frequency signal in the second frequency band f2 to the master UE 404. In this way, the master UE 404 may receive the radio frequency signal originated from the network node 402 from the cooperative UE 406 in the second frequency band f2 through an indirect path.

[0050] To support device collaboration, various techniques, methods, schemes and / or solutions related to configuring measurement resources and CSI reporting are described below.

[0051] In some embodiments, in a first frequency band (e.g., Figure 2 , Figure 3 or Figure 4 A communication device (e.g., a master communication device or a master UE in device cooperative communication) receiving a signal from a network node may transmit a capability report to the network node. The capability report may include information related to the capability of supporting device cooperation and / or information related to at least one second frequency band (e.g., Figure 2 , Figure 3 or Figure 4 The second frequency band f2) in the device collaboration is performed.

[0052] In some embodiments, before or after transmitting the capability report to the network node, the primary communication device may negotiate or communicate with a cooperative device (e.g., a cooperative communication device or a cooperative UE in device cooperative communication) about a frequency band for performing device cooperation. Please note that in some embodiments, there may be more than one cooperative device performing device cooperation with the primary communication device, and therefore more than one frequency band may be determined or selected to perform device cooperation.

[0053] In some embodiments, the frequency band for performing device cooperation may be a licensed frequency band or an unlicensed frequency band. In some embodiments, it may be necessary to obtain permission from the network node to use the frequency band for device cooperation. The primary communication device may negotiate or communicate with the network node about the frequency band for performing device cooperation before or through the transmission capability report to the network node.

[0054] In some embodiments, if the primary communication device has reported its upgraded capability and / or the capability of supporting device cooperation to the network node (e.g., through a capability report), the primary communication device may receive from the network node a first reporting configuration associated with at least one first measurement resource allocated in a first frequency band. In some embodiments, the measurement resource may be one of the following types: a synchronization signal (SS) block or a physical broadcast channel (PBCH) block (SS / PBCH block, SSB), a non-zero power channel state information reference signal (NZP-CSI-RS), a CSI interference measurement (CSI-IM), a tracking reference signal (TRS), and a demodulation reference signal (DMRS).

[0055] In some embodiments, the primary communication device may determine information related to second measurement resources allocated in the second frequency band.In some embodiments, the first frequency band may be different from the second frequency band.

[0056] The primary communication device may receive a first radio frequency signal carrying one or more reference signals on a first measurement resource, and receive a second radio frequency signal carrying one or more reference signals on a second measurement resource. In some embodiments, the one or more reference signals carried in the first radio frequency signal and the one or more reference signals carried in the second radio frequency signal may be the same.

[0057] Regarding the configuration of configuring measurement resources in two component carriers or two frequency bands (e.g., frequency bands f1 and f2) for device cooperative communication, in one aspect, the first reporting configuration may be further associated with the second measurement resource. That is, the first reporting configuration may be associated with the first measurement resource and the second measurement resource, and thus, one report may be associated with two measurement resources spanning two component carriers or two frequency bands. In such an embodiment, the information about the second measurement resource may be explicitly indicated by the first reporting configuration, or may be determined based on the first reporting configuration.

[0058] In some embodiments, the primary communication device may perform channel state measurement of one or more reference signals based on at least one of the first RF signal and the second RF signal, and generate a channel state information (CSI) report based on the first reporting configuration and the channel state measurement on at least one of the first measurement resource and the second measurement resource (for example, on one or both of the first measurement resource and the second measurement resource).

[0059] From the perspective of the master communication device, the measurement resources are configured in at least two frequency bands (e.g., frequency bands f1 and f2). One report is associated with at least two resources in the two frequency bands. The master communication device can derive CSI (e.g., perform channel state measurement and generate CSI reports accordingly) by jointly considering reference signals (RS) received in frequency bands f1 and f2. From the perspective of the network node, the two resources are transmitted as a single resource in one frequency band (e.g., frequency band f1).

[0060] In another aspect, with respect to configuring measurement resources in two component carriers or two frequency bands for device cooperative communication, the second measurement resource may be mapped from the first measurement resource, and the mapping between the first measurement resource and the second measurement resource may include an offset in the frequency domain.

[0061] In some embodiments, in the first reporting configuration, the primary communication device may be configured with measurement resources in frequency band f1, and the first reporting configuration may be associated only with the first measurement resources. That is, the first reporting configuration may be associated with measurement resources in frequency band f1, but not with measurement resources in frequency band f2. In such an embodiment, information about the second measurement resource may be implicitly indicated by the first reporting configuration, or may be derived from the first reporting configuration. For example, based on the setting of the first measurement resource obtained by the first reporting configuration and the frequency conversion mapping rule from f1 to f2, the primary communication device may derive the allocation of the second measurement resource. In addition, one CSI report may be associated with two measurement resources spanning two components or two frequency bands.

[0062] In some embodiments, the first reporting configuration may include an indicator indicating whether the CSI report is generated based on channel state measurements on the first measurement resources, channel state measurements on the second measurement resources, or channel state measurements on both the first measurement resources and the second measurement resources.

[0063] In some embodiments, the first reporting configuration may include an indicator (e.g., an indicator frequencyTranslationON) indicating whether frequency translation is turned on. If the indicator indicates that frequency translation is turned on, in this case, the primary communication device may assume that the signal transmitted by the network node in frequency band f1 is also transmitted in frequency band f2 (or even in more frequency bands such as f3, f4, etc. when there are more than one cooperating devices performing device cooperation with the primary communication device), and information about the second measurement resource may be derived from the first reporting configuration.

[0064] Please note that when there is more than one cooperating device performing device cooperation with the master communication apparatus, there may be more than one indicator to indicate whether to turn on the frequency conversion, and each indicator may correspond to a separate cooperating device or a separate frequency conversion.

[0065] In some embodiments, whether the value of the indicator frequencyTranslationON is set to true (true) can be indicated in the corresponding reporting configuration. If the indicator frequencyTranslationON==TRUE, in this case, the primary communication device can assume that all reference signals received in frequency band f1 are frequency converted to frequency band f2 (or even more frequency bands, such as f3, f4, etc.), and derive CSI by considering the reference signals received in multiple frequency bands (e.g., f1 and f2) separately and / or jointly. If the indicator frequencyTranslationON==FALSE, in this case, the primary communication device can derive CSI based on the relevant reference signals received in frequency band f1.

[0066] In some embodiments, if the indicator frequencyTranslationON is turned on or set to true, the primary communication device may negotiate with the cooperation device on the behavior in the device cooperation communication.

[0067] In some embodiments, a predefined mapping or preconfigured rules may be issued to the primary communication device, which may describe the content of the frequency conversion and map the resources in the frequency band f1 to the resources in the frequency band f2. In some embodiments, the mapping may be a constant offset in the frequency domain. In some embodiments, the information about the second measurement resource may be derived from the first reporting configuration based on the predefined mapping or based on the preconfigured rules.

[0068] Regarding the quasi co-location (QCL) rule for measurement resource reception in frequency band f2, the primary communication device may follow the QCL rule of frequency band f1. In some embodiments, the primary communication device may apply a first QCL rule to receive a first RF signal and apply a second QCL rule to receive a second RF signal, wherein the second QCL rule is the same as the first QCL rule. Please note that the implementation of applying the same QCL rule in device cooperative communication may apply to type A, type B, type C, type D, or any combination thereof. In one example, the QCL rule applied in frequency band f1 followed by frequency band f2 may not use SSB as the QCL source.

[0069] Please note that when there are more than one cooperative devices performing device cooperation with the primary communication device, each cooperative device may correspond to at least one QCL rule. The primary communication device may apply the corresponding QCL rule to receive the RF signal from each cooperative device.

[0070] In some embodiments, the QCL rules may be configured based on the reporting configuration or based on the measurement resources. When the QCL rules are configured based on the measurement resources, each frequency band (e.g., frequency bands f1, f2, f3, f4, etc.) may have a corresponding QCL rule. When the QCL rules are configured based on the reporting configuration, the QCL rules configured for frequency band f1 may be followed by other frequency bands f2, f3, f4, etc. (e.g., applied in other frequency bands f2, f3, f4, etc.).

[0071] In another aspect regarding configuring measurement resources in two (or more) component carriers or two (or more) frequency bands for device cooperative communication, a network node may provide multiple reporting configurations. In some embodiments, the primary communication device may receive at least a first reporting configuration and a second reporting configuration from the network node, wherein the first reporting configuration corresponds to a first path, the second reporting configuration corresponds to the first path and the second path, or the first reporting configuration is associated with the first measurement resource, and the second reporting configuration is associated with the second measurement resource.

[0072] In some embodiments, the first path may be a direct path and the second path may be an indirect path. The primary communication device may receive a first RF signal carrying one or more reference signals on a first measurement resource through the first path, and receive a second RF signal carrying one or more reference signals on a second measurement resource through the second path. In some embodiments, the one or more reference signals carried in the first RF signal and the one or more reference signals carried in the second RF signal may be the same.

[0073] The primary communication device may perform channel state measurement of the one or more reference signals on the first measurement resource, and generate a first channel state information report based on the first report configuration and the channel state measurement on the first measurement resource. The primary communication device may perform channel state measurement of the one or more reference signals on the second measurement resource, and generate a second channel state information report based on the second report configuration and the channel state measurement on the second measurement resource. The primary communication device may also perform channel state measurement of the one or more reference signals on the first measurement resource and the second measurement resource, and generate a channel state information report based on the channel state measurement on the first measurement resource and the second measurement resource.

[0074] In certain embodiments of multiple reporting configurations in device cooperative communication, the primary communication device may receive a first reporting configuration, a second reporting configuration, and a third reporting configuration from a network node, wherein the first reporting configuration is associated with a first measurement resource and / or corresponds to a first path (e.g., a direct path), the second reporting configuration is associated with a second measurement resource and / or corresponds to a second path (e.g., an indirect path), and the third reporting configuration is associated with the first measurement resource and the second measurement resource and / or corresponds to the first path and the second path.

[0075] The primary communication device may perform channel state measurement of the one or more reference signals on the first measurement resource, and generate a first channel state information report based on the channel state measurement on the first measurement resource. The primary communication device may perform channel state measurement of the one or more reference signals on the second measurement resource, and generate a second channel state information report based on the channel state measurement on the second measurement resource. The primary communication device may perform channel state measurement or joint channel state measurement on the first measurement resource and the second measurement resource, and generate a third channel state information report based on the channel state measurement or joint channel state measurement on the first measurement resource and the second measurement resource. One channel state information report is associated with one report configuration.

[0076] In certain embodiments of multiple reporting configurations in device cooperative communication, the primary communication device may receive an indication from a network node via radio resource control (RRC) signaling or signaling based on a physical downlink control channel (PDCCH), such as downlink control information (DCI) indicating whether a channel state information report is generated based on a channel state measurement on a first measurement resource or a second measurement resource, or based on a channel state measurement on the first measurement resource and the second measurement resource.

[0077] In some embodiments, the indication for indicating which channel state measurements are based on which the channel state information report is generated may be the aforementioned indicator frequencyTranslationON or an indicator of the path selection result. In one example, the on or off (or TRUE or FALSE) information of the frequency conversion may be configured directly in the report configuration. For the channel state information report to be generated, the relevant report configuration explicitly indicates whether to jointly consider the reference signal received in the frequency band (e.g., frequency band f2) of the device collaboration due to the frequency conversion.

[0078] In some embodiments, in order to dynamically adjust or dynamically select between different transmission paths, the indication for indicating which channel state measurements are used to generate the channel state information report may be dynamically provided by the network node through PDCCH-based signaling.

[0079] In some embodiments, for mode-dependent methods, an indicator (e.g., an indicator frequencyTranslationON or an indicator of a path selection result) may be used to indicate whether the primary communication device should assume that signals transmitted by the network node in frequency band f1 are also transmitted in frequency band f2. The above indicator may be included in the reporting configuration.

[0080] In some embodiments, the channel state measurement to be performed by the primary communication device may depend on whether frequency switching is enabled. For the channel state information report (or corresponding reporting configuration), the primary communication device may consider the on / off mode of the frequency switching of the cooperative communication device (or consider the path selection result) to determine whether to jointly consider the reference signal received in the frequency band of the device cooperation (e.g., frequency band f2).

[0081] In one example, for Figure 2 For the diversity enhancement scenario shown in FIG. 1 , if the reference signal used for measurement is expected to be forwarded, the channel state information can be derived based on the reference signal measured in frequency band f2. Otherwise, the channel state information can be derived based on the reference signal measured only in frequency band f1. In another example, for example Figure 3 For the rank enhancement scenario shown, if the reference signal used for measurement is expected to be forwarded, the channel state information can be derived from the reference signal measured in frequency band f2. Otherwise, the channel state information can be derived from the reference signal measured only in frequency band f1.

[0082] In some embodiments, in order to dynamically adjust or dynamically select paths between different transmission paths, when the reporting configuration includes an indicator, PDCCH-based signaling may be used to indicate the dynamic switching or path selection result.

[0083] Please note that in some embodiments, in order to save configuration overhead, the indication for indicating which channel state measurements are used to generate the channel state information report (such as the aforementioned indicator frequencyTranslationON or the indicator of the path selection result) may not be included in the report configuration. In these embodiments, the indication may be provided to the primary communication device via any type of signaling.

[0084] Regarding the operation of a network node in device collaborative communication, in some embodiments, the network node may receive a capability report from a communication device (e.g., a master communication device) that receives a signal from the network node in a first frequency band, wherein the capability report includes information related to capabilities for supporting device collaboration and information related to at least one second frequency band different from the first frequency band to perform device collaboration.

[0085] Based on the information carried in the capability report, the network node may configure a first measurement resource in the first frequency band and transmit a first report configuration associated with the first measurement resource to the communication device. In some embodiments, information related to the second measurement resource allocated in the second frequency band may be implicitly or explicitly indicated by the first report configuration.

[0086] In one example of explicit indication, the first reporting configuration may be associated with the first measurement resource and the second measurement resource, and the information related to the second measurement resource may be determined based on the first reporting configuration.

[0087] In one example of implicit indication, the second measurement resource may be mapped from the first measurement resource, and the mapping between the first measurement resource and the second measurement resource may include an offset in the frequency domain.

[0088] In some embodiments, the first reporting configuration may include an indicator indicating whether frequency switching is turned on. In the event that the indicator indicates that frequency switching is turned on, the information related to the second measurement resource may be derived from the first reporting configuration.

[0089] In some embodiments, the network node may configure multiple measurement resources corresponding to multiple transmission paths, such as a direct path and one or more indirect paths, and transmit multiple reporting configurations to the communication device, wherein each reporting configuration is associated with one measurement resource.

[0090] In certain embodiments of multiple reporting configurations in device cooperative communications, a network node may transmit an indication via radio resource control signaling or PDCCH-based signaling (such as DCI) that indicates which channel state measurements (or which transmission path's channel state measurements) the communication device is based on to generate a channel state information report.
