Such communication nodes may be capable of wireless and / or wired communications, in accordance with various embodiments of the present solution.
[0022] FIG. 2 illustrates a block diagram of an example wireless communication system 200 for transmitting and receiving wireless communication signals (e.g., OFDM / OFDMA signals) in accordance with some embodiments of the present solution. The system 200 may include components and elements configured to support known or conventional operating features that need not be described in detail herein. In one illustrative embodiment, system 200 can be used to communicate (e.g., transmit and receive) data symbols in a wireless communication environment such as the wireless communication environment 100 of Figure 1, as described above.

[0025] In accordance with some embodiments, the UE transceiver 230 may be referred to herein as an “uplink” transceiver 230 that includes a radio frequency (RF) transmitter and a RF receiver each comprising circuitry that is coupled to the antenna 232.

The operations of the two transceiver modules 210 and 230 may be coordinated in time such that the uplink receiver circuitry is coupled to the uplink antenna 232 for reception of transmissions over the wireless transmission link 250 at the same time that the downlink transmitter is coupled to the downlink antenna 212. Conversely, the operations of the two transceivers 210 and 230 may be coordinated in time such that the downlink receiver is coupled to the downlink antenna 212 for reception of transmissions over the wireless transmission link 250 at the same time that the uplink transmitter is coupled to the uplink antenna 232. In some embodiments, there is close time synchronization with a minimal guard time between changes in duplex direction.
[0026] The UE transceiver 230 and the base station transceiver 210 are configured to communicate via the wireless data communication link 250, and cooperate with a suitably configured RF antenna arrangement 212 / 232 that can support a particular wireless communication protocol and modulation scheme.

[0032] 2. Systems and Methods for Performing Channel Measurement and Reporting
[0033] The wavefront propagation characteristics for the channel between the base station (BS) and different user equipments (UEs) may exhibit different characteristics. For example, with the increasing antenna aperture size of the BS, the wavefront propagation for the channel between the BS and some UEs near the BS may exhibit spherical-wavefront propagation characteristics (or non-planar wavefront propagation characteristics) , while the wavefront propagation for the channel between the BS and some UEs far away from the BS may exhibit planar-wave propagation characteristics (or far-field propagation characteristics) . In some implementations, different wavefront propagation characteristics and / or channel characteristics can be a significant factor for the BS to determine the technical and scheduling solutions for UEs. As a result, it may be desirable for the BS to know and / or differentiate the detailed channel propagation characteristics between the BS and UEs to make suitable scheduling decisions for different UEs.
[0034] In some implementations, the wavefront propagation characteristics between the BS and one or more UEs can be assumed to be the same wavefront propagation (e.g., planar wavefront propagation) . In some implementations, the BS can configure the reference signal (RS) resource configuration and / or report configuration for the UE to measure the RSs and feedback the channel state information. In some implementations, there may be different wavefront propagation characteristics for the channel between the BS and different UEs. In some implementations, for the BS to know / determine the specific channel propagation characteristics between the BS and UE, some enhancements / implementations / configurations may be considered for the existing channel measurement procedures.
[0035] In some implementations, the design principle can be based on the two-stage codebook structure, for example, W=W1*W2, where the first matrix W1 can be used to represent the wideband beam group selected according to the long-term wideband characteristics of the channel, and the second matrix W2 can be used to further capture the short-term and sub-band characteristics of the channel.
[0036] In some implementations, the second matrix can be used to select the beam according to the short sub-band characteristics of the channel. In some implementations, the second matrix can be used to determine and / or quantify the phase difference between the two polarization directions to achieve the phase combination between the two polarizations. In some implementations, in addition to the phase difference between the two polarizations, there may be a power imbalance between the different polarizations that may not be reflected in the existing codebook design. In this regard, one or more enhancements / implementations / configurations can be considered for the existing codebook design and / or the reported PMI content.
[0037] In some implementations, the RS resource settings and / or the report settings can be configured by the BS and / or transmitted to the UE from the BS for measuring the channel state information. Each RS resource setting (e.g., CSI-ResourceConfig) may include a configuration of a list of one or more CSI resource sets. In some implementations, the list may include references to NZP-CSI-RS resource sets and / or SSB sets. In some implementations, the list may include references to CSI-IM resource sets. For each NZP-CSI-RS resource, the time information, frequency information, port information, etc., can be configured for the UE.
[0038] In some implementations, each report setting may include the parameter for one CSI reporting band, including, but not limited to, codebook configuration, time-domain behavior for the report, frequency granularity for CQI and PMI, measurement restriction configurations, and / or the CSI-related quantities (e.g., LI, L1-RSRP, L1-SINR, CRI, SSBRI) , among others.
[0039] In some implementations, for example, Type I single panel codebooks, when the number of layers v∈ {2, 3, 4} , each PMI value can correspond to four codebook indices {i1, 1, i1, 2, i1, 3, i2}. In some implementations, when the number of layers v=1, each PMI value can correspond to three codebook indices {i1, 1, i1, 2, }. The composite codebook index i1 can be defined by i1={i1, 1, i1, 2, i1, 3, i2} por v∈ {2, 3, 4} , and The composite codebook index i1 can be used for selecting and determining the beams, and the codebook index i2 can be used to adjust the phase among different polarizations.
[0040] In some embodiments / implementations, for the BS to know the specific channel propagation characteristics between the BS and UE, several aspects / implementations may be considered. In certain aspects / implementations, the first configuration information related to the measurement operation and / or report operation can be configured to the UE. In some implementations, the first configuration information may include antenna port information. In non-limiting examples, the antenna port information may include first antenna port information and / or second antenna port information. The first antenna port information can be used to indicate the antenna port information that the UE may use for channel measurement. In some implementations, the second antenna port information can be the antenna port information using which an RS resource can be transmitted. For example, the second antenna port information can be the existing CSI-RS antenna port information configured by nrofPorts. The antenna port index / number of an RS resource can be calculated according to pre-defined configurations.
[0041] In non-limiting examples, the first antenna port information may refer to the second antenna port information. In some implementations, one or more cases regarding the format of the first antenna port information can be considered. In some implementations, the first antenna port information may include one or more antenna port group (s) . Each antenna port group may include one or more antenna port information. In some implementations, the antenna port information of a RS resource (e.g., the antenna port that the RS is transmitted) can be configured by the second antenna port information (e.g., existing signaling nrofPorts) . The one or more antenna port information of each antenna port group indicated in the first antenna port information can refer to the antenna port information indicated in the second antenna port information. In some implementations, each antenna group may include one antenna port information. In some implementations, the first antenna port information may include one or more antenna port information. Each antenna port indicated in the first antenna port information can be treated / configured as an antenna port group.
[0042] In some implementations, one or more cases / implementations / options can be considered to indicate / represent the antenna port group information of the first antenna port information. In some implementations, one or more values can be used to indicate the number of antenna ports for each antenna port group. In some examples, a value can be used to indicate how many antenna ports of an RS resource can be grouped into an antenna port group. For example, a NZP-CSI-RS resource with index 1 configured with 8 CSI-RS ports can be configured for a UE, and the CSI-RS port indexes can be 3000-3007. For instance, a value of 4 configured for the first antenna port information may mean / indicate that the first four CSI-RS ports (e.g., ports 3000-3003) can be treated / configured as one antenna port group, and the last four CSI-RS ports (e.g., ports 3004-3007) can be treated / configured as the other antenna port group.
[0043] In some examples, each value can be used to indicate how many antenna ports of an RS resource can be treated as an antenna port group. In some implementations, one or more values can be configured for the first antenna port information. For example, a NZP-CSI-RS resource with index 1 configured with 16 CSI-RS ports can be configured for a UE, and the CSI-RS port indexes can be 3000-3015. For example, three values of 4, 4, 8 configured in the first measurement configuration information may mean / indicate that there are 3 CSI-RS antenna port groups in total. For instance, the first 4 CSI-RS ports (e.g., ports 3000-3003) can be treated / configured as the first antenna ports group, the next 4 CSI-RS ports with indexes 3004-3007 can be treated / configured as the second antenna ports group, and the last 8 CSI-RS ports (e.g., ports 3008-3015) can be treated / configured as the third CSI-RS antenna ports group.
[0044] In some implementations, a value can be used to indicate the number of antenna port groups for each RS resource. In some examples, a value, for example, used to indicate how many antenna port groups the ports of an RS resource can be divided into, can be configured for the first antenna port information. For example, a NZP-CSI-RS resource with index 1 configured with 16 CSI-RS ports can be configured for a UE, and the CSI-RS port indexes can be 3000-3015. In some implementations, a value of 2 configured for the first antenna port information may mean / indicate that there are 2 antenna port groups in total. Each antenna port group can have 8 CSI-RS ports. For instance, the first 8 CSI-RS ports (e.g., ports 3000-3007) can be treated / configured as one antenna port group, and the last 8 CSI-RS ports (e.g., ports 3008-3015) can be treated / configured as the other antenna port group.
[0045] In some implementations, each value can be used to indicate / represent the antenna port index of an RS resource. In some implementations, one or more values can be configured to indicate CSI-RS port group information. In some examples, a NZP-CSI-RS resource with index 1 configured with 8 CSI-RS ports can be configured for a UE, and the CSI-RS port indexes can be 3000-3007. In some implementations, a value of 0~7 can be used to represent the corresponding 8 CSI-RS ports of the NZP-CSI-RS resource with index 1. For example, the values 1, 2, and / or 4 can be configured in the first measurement configuration information to indicate CSI-RS antenna port group information.
[0046] In some examples, a NZP-CSI-RS resource with index 1 configured with 8 CSI-RS ports can be configured for a UE, and the CSI-RS port indexes can be 3000-3007. In some implementations, a value of 0~7 can be used to represent the corresponding 8 CSI-RS ports of the NZP-CSI-RS resource with index 1. For example, the first antenna port information may include two CSI-RS antenna port groups. In this regard, one CSI-RS port group information, including the values 1, 2 and / or 4, may mean / indicate that the BS wants / requests the UE to measure the channel information of one CSI-RS port group including the CSI-RS ports 3001, 3002 and / or 3004. The other CSI-RS port group information, including the values 0, 3, and / or 5, may mean / indicate that the BS wants / requests the UE to measure the channel information of the CSI-RS port group, including the CSI-RS ports 3000, 3003, and / or 3005.
[0047] In some examples, there may be a mapping relationship between the antenna port and the physical antenna elements. In some examples, in order to know the detailed channel characteristics, even for the same antenna port, there may be different mapped physical antenna elements. In this manner, in some examples, the first antenna port information can be used for the channel measurement. In some implementations, the first antenna port information can be different from the antenna port that is defined and used, such that the channel over which a symbol on the antenna port is conveyed can be inferred from the channel over which another symbol on the same antenna port is conveyed.
[0048] In some implementations, the first configuration information may include the measurement and report configuration information. The measurement and report configuration information may include at least one of different types of information: the one or more first report quantity information, the one or more first codebook related information, the one or more channel propagation characteristic information, or the one or more report type information. The first report quantity information can be used to indicate the report quantity associated with the first antenna port information. In some implementations, the first report quantity information may include at least one of the following: Precoding matrix indicator (PMI) information, Channel quality indicator (CQI) information, Rank information, Layer information, RSRP information, SINR information, SIR information, Phase information, Amplitude information, RS resource index information, Antenna port index information, and / or antenna port group information, among others.
[0049] In some implementations, the second report quantity information can be the report quantity information configured by the existing reportQuantity. In some implementations, the first report quantity information can directly refer to the second report quantity information configured by the reportQuantity of the present disclosure.
[0050] In some implementation, the first codebook related information may include at least one of the following: the reported codebook type (e.g., Type I or Type II codebook, or a new codebook type) and / or the related parameters used to calculate / determine the codebook. In some implementations, the different codebook type (s) can implicitly refer to the different channel propagation characteristics. For example, the channel characteristics between the BS and UE may exhibit the planar-wavefront assumption and / or the non-planar-wavefront assumption. In some implementations, different channel propagation characteristics may desire different codebook type (s) . In some examples, the Type I and Type II codebooks can be applicable for planar-wavefront channel characteristics, and the Type III codebook can be applicable for non-planar-wavefront channel characteristics. In some examples, when the first codebook related information includes the Type I / II codebook and related parameters, the information can implicitly indicate that the UE can assume the channel propagation characteristics as a planar-wavefront assumption and / or can perform the corresponding channel measurement. In some examples, when the first codebook related information includes the Type III codebook and related parameters, the information can implicitly indicate that the UE can assume the channel propagation characteristics as a non-planar-wavefront assumption and / or perform the corresponding channel measurement.
[0051] In some implementations, the one or more channel propagation characteristic information can be used to indicate the channel propagation characteristics (e.g., the planar-wavefront, the non-planar-wavefront, the spherical-wavefront, among others) .
[0052] In some implementations, the first report type information can be used to indicate a report type and / or reported resource information. The report type can be a periodic report, a semi-persistent report, or an aperiodic report. The reported resource information may include time resource information, frequency resource information, and / or channel type (e.g., the PUCCH or the PUSCH) used for the report.
[0053] In some implementations, each type of measurement and report information can be applicable for an antenna port group indicated in the first antenna port information. In some implementations, each antenna port group indicated in the first antenna port information can be configured with one or more first report quantity information. This may mean / indicate that the UE is to measure different quantities on the corresponding antenna port group and report. In some implementations, each antenna port group indicated in the first antenna port information can be configured with one or more first codebook related information. For example, there can be three types of codebooks: the Type I and Type II codebooks can be applicable for planar-wavefront channel characteristics, and the Type III can be applicable for non-planar-wavefront channel characteristics. For an antenna port group in a first antenna port information, there can be two first codebook related information, one includes the Type I codebook and related parameters, and the other includes the Type III codebook and related parameters. In this manner, the UE can perform the channel measurement and calculate the codebook for the antenna ports indicated in the antenna port group under different codebook type (s) . In some implementations, each antenna port group indicated in the first antenna port information can be configured with one or more first report type information. For example, for an antenna port group, when there are two first-codebook-related-information, there can be two first-report-type-information. This may mean / indicate that for different first codebook related information, different first report type information can be associated with it. In some implementations, each antenna port group indicated in the first antenna port information can be configured with one or more channel characteristics information. For example, for an antenna port group, when there are two channel characteristics information including the planar-wavefront characteristics and non-planar-wavefront characteristics, the UE can perform the channel measurement under the different channel characteristics assumption.
[0054] In some implementations, for an antenna port group indicated in the first antenna port information, when there are one or more multiple types of measurement and report information, the relationship between different types of measurement and report information can be at least one of the following: one-to-one association / mapping or one-to-multiple association / mapping.

In some implementations, for the first report type information, there can be one or more associated first codebook related information. In some implementations, for one or more first report type information, there can be one or more associated first codebook related information. In some implementations, for an antenna port group, when it has been configured with the first report quantity information, two first-codebook-related-information, and / or two first-report-type-information, this may mean that the first report quantity information is applicable / associated to / with the two first-codebook-related-information and two first-report-type-information. The two first-codebook-related-information can be respectively associated to / with the two first-report-type-information. The UE can perform the channel measurement over the antenna port group and calculate different types of codebooks according to the configured two first-codebook-related-information and / or report the respective results according to associated two first-report-type-information.
[0055] In some implementations, each type of measurement and / or report information can be applicable for all antenna port groups indicated in the first antenna port information. In some implementations, each type of measurement and / or report information can be applicable for one or more antenna port groups indicated in the first antenna port information.

In some implementations, the first resource index information can be used to indicate the RS resources (indexes) that the first configuration information is associated with. In some implementations, the first resource index information may include one or more first index information. In some implementations, the RS resources and / or the RS resource sets can be configured to the UE by the BS. Each RS resource and / or RS resource set may have an index to identify each RS resource or RS resource set. In this manner, the first resource index information can be used to indicate one or more RS resource / RS resource set indexes.
[0057] In some implementations, each first index can be used to indicate / represent an RS resource. For example, the first index can be the existing RS resource ID / index, e.g., the existing NZP-CSI-RS-ResourceId. In some implementations, each first index can be used to indicate an RS resource set. For example, the first index can be the existing RS resource set index / ID, e.g., the existing NZP-CSI-RS-ResourceSetId. In some implementations, each first index can be used to indicate / represent a group of one or more RS resource sets. For example, the first index can be the existing CSI-ResourceConfigId.
[0058] In some implementations, each first configuration information may have a second index information to be used to identify each first configuration information. In some examples, the different types of configuration information mentioned herein can be grouped / associated as a measurement information pair / list. In some implementations, each first configuration information may include one or more measurement information groups / pairs / lists. In some implementations, the types of information that are not included in the measurement information group / pair / list can have a separate field. In some implementations, each measurement information pair may have a third index information to identify each measurement information pair.

[0059] In some implementations, regarding signaling the first configuration information to the UE, one or more configurations / methods / implementations can be considered. In some implementations, one or more first configuration information can be configured to the UE via RRC signaling. In some implementations, the RRC signaling can be a new RRC signaling or an existing signaling. In some implementations, the RRC signaling can be a new RRC signaling used to configure one or more first configuration information. In some implementations, the RRC signaling can be an existing report configuration signaling, for example, the RRC signaling can be the CSI-ReportConfig signaling. In some implementations, where there is no second index configured in the first configuration information, this may mean / indicate that the first configuration information can be applicable to all (or a certain number of) RS resources configured for the channel measurement.
[0060] In some implementations, the RRC signaling can be the existing CSI-AperiodicTriggerStateList. For example, the RRC signaling can be the existing CSI-SemiPersistentOnPUSCH-TriggerStateList. In this manner, when the corresponding state has been triggered, the UE can perform the measurement and / or reporting according to the information provided in the first configuration information. In some implementations, the RRC signaling can be the existing RS resource configuration signaling. For example, the RRC signaling can be the existing CSI-ResourceConfig, NZP-CSI-RS-Resource, or NZP-CSI-RS-ResourceSet signaling. In some implementations, where the first measurement configuration information may not include the second index information, the first configuration information can be applicable to all (or a certain number of) RS resources indicated in the corresponding RRC signaling.
[0061] In some implementations, one or more first configuration information can be configured to the UE via RRC signaling. In some implementations, a MAC CE signaling can be used to trigger one or more first configuration information configured in the RRC signaling. In some implementations, the UE can perform the measurement and report operation according to the triggered first configuration information. In this manner, the MAC CE signaling can be a new MAC CE signaling or an existing MAC CE signaling. For example, the MAC CE signaling can be the existing SP CSI reporting on PUCCH Activation / Deactivation MAC CE. In some implementations, one or more fields can be added to the MAC CE signaling, where each field can be used to indicate whether a configured first configuration information in the RRC signaling has been activated or not. In some implementations, different multiple fields can correspond to different activation / deactivation of the corresponding multiple first configuration information in the RRC signaling.
[0062] In some implementations, one or more first configuration information can be configured to the UE via MAC CE signaling. In some implementations, the MAC CE signaling can be an existing MAC CE signaling or a new MAC CE signaling. In some implementations, the MAC CE signaling can be the SP CSI reporting on PUCCH Activation / Deactivation MAC CE. In some implementations, after receiving the configuration information from the BS, the UE can perform the channel measurement over the corresponding antenna ports of RS resources, and report all the results according to the first configuration information. In some implementations, for the one or more antenna port groups indicated in the first antenna port information, when there are the same first report quantity information configured, the reported results of the one or more antenna port groups can be at least one of the following: the results value of all (or a certain number of) antenna port groups, the maximum or minimum results value of reported quantity over all (or a certain number of) antenna port groups, and / or the results value of reported quantity measured on antenna port groups satisfying the specific rule. In some implementations, this rule can be predefined for BS and UE, defined for the UE from the BS, and / or defined for the UE and the BS from the OAM. In some implementations, the rule can indicate / specify that the result value is larger / greater or smaller than a threshold value. For example, a threshold is configured for the UE, and those result values of antenna port groups that are larger / greater than the threshold value can be reported by the UE to the BS. In some implementations, this rule can be pre-defined for the UE and BS. The threshold value can be configured to the UE by the BS, pre-defined for the BS and UE, and / or configured to the UE by the OAM.
[0063] In some implementations, regarding the result values of reported quantities, at least one of the following can be considered: the value can be the actual value, the value can be the difference value, and / or the value can be the quantified value. In some implementations, the reported value can directly be the measured actual or filtered value of a reported quantity measured on an antenna port group. For example, when the reported quantity is set / defined / configured as the RSRP, the reported value can directly be the measured actual value of RSRP. In some implementations, the reported value can be the difference value measured and calculated over different antenna port groups configured in the first configuration information. In some implementations, the difference value can be obtained / received / acquired by calculating the difference between the measured result values of two CSI-RS port groups. In some implementations, the difference value can be obtained / received / obtained by calculating the difference between the measured result values of an antenna port group and a reference value. In some implementations, the reference value can be indicated from the BS to the UE or can be pre-defined for the BS and the UE.
[0064] In some implementations, the reported value can be the quantified value of the reported quantity. In some implementations, the quantified value can be obtained by quantifying the actual value according to a quantify rule or table, as shown below. For example, there can be one or more threshold values in the quantify table / rule. In some implementations, the measured actual value / difference value can be quantified according to the one or more threshold values given in the quantify table / rule. In some implementations, the quantified method / table can be pre-defined for the BS and UE, or configured to the UE by the BS.
[0065] Example 1: Single threshold for quantifying the measured value
[0066] Example 2: Three thresholds for quantifying the measured value
[0067] In some examples, the value can be any one or more combinations of formats mentioned / described herein. For example, the value can be the differenced and / or quantified value. In some implementations, as described herein, regarding the reported results information, the index information can be considered. In some implementations, the index information can be the first index information or the second index information.
[0068] In some implementations, for an antenna port group indicated in the first antenna information, when there is one or more first codebook related information configured, the reported results of the antenna port group can be at least one of the following: all (or a certain number of) results measured under the different first codebook related information, the difference value of results measured under the different first codebook related information, the maximum or minimum value of results measured under the different first codebook related information, and / or the value of results measured under the different first codebook related information satisfying a specific rule. In some implementations, for an antenna port group indicated in the first antenna information, when there is one or more first codebook related information configured, the reported order of different results measured according to the different first codebook related information can be at least one of: following the same rule of one or more first codebook related information configured in the first configuration or following a pre-defined rule. In some implementations, the pre-defined rule can be the order of different codebook type (s) . In some implementations, when there are three different codebook type (s) , including Type I, Type II and Type III codebook, the pre-defined rule can be that the reported order may first report the Type I codebook if configured, then the Type II codebook if configured, then the Type III codebook if configured, or vice versa. In some implementations, for an antenna port group indicated in the first antenna information, when there is one or more first codebook related information configured, the results measured and calculated under the different first codebook related information can be reported together (e.g., reported via the same channel (e.g., PUCCH, PUSCH, etc. ) or reported separately (e.g., via different channel, or via the same channel with different time and / frequency resources) . In some implementations, for an antenna port group indicated in the first antenna information, when the first codebook related information is configured, the results measured and calculated under the first codebook related information can be reported together (e.g., reported via the same channel (e.g., PUCCH, PUSCH, etc. ) or reported separately (e.g., via different channel, or via the same channel with different time and / frequency resources) .
[0069] In some implementations / embodiments, the power difference between two polarizations can be considered in the codebook design and / or the reported PMI content. In this manner, one or more methods / implementations / configurations can be considered. In some implementations, a new parameter / codebook index (e.g., i3) can be added to each PMI value, which may include a value to reflect the polarization power / amplitude difference between different polarizations. In some implementations, regarding the feedback overhead, a mapping table between the different value of i3 and the quantified polarization power / amplitude difference value can be defined. In this manner, when the UE calculates the actual polarization power / amplitude difference value, the UE can first quantify the actual polarization power / amplitude difference value according to the quantified power difference value given in the table. In some implementations, according to the mapping relationship between the value of i3 and the quantified power difference value, the UE can determine / obtain / acquire the value of i3. For example, as shown below, when the UE calculates / determines that the actual polarization power / amplitude difference value is quantified to A1, the UE can determine that the reported value of i3 is 0.
[0070] In some implementations, a combined new parameter / codebook index (e.g., i3) can be added to each PMI value, which may include one or more values to reflect the polarization power / amplitude value for the corresponding polarization. For example, one or more new parameters / codebook indexes can be added to each PMI value to reflect the polarization power / amplitude value for the corresponding polarization. In some implementations, regarding the two polarizations, the new parameter / codebook index (i.e, i3) may include two values where can be used to reflect / indicate the power / amplitude coefficient for one polarization p1 and can be used to reflect / indicate the power / amplitude coefficient for another polarization p2.
[0071] In some implementations, a mapping table between different values of and the quantified polarization power / amplitude value can be defined, where can represent / indicate the reported value for each polarization. In this manner, when the UE calculates the actual polarization power / amplitude value for different polarizations, the UE can first quantify the actual polarization power / amplitude value for each polarization according to the quantified power value given in the table. In some implementations, according to the mapping relationship between the value of and the quantified power value, the UE can obtain the value of For example, as shown below, when the UE calculates / determines that the quantified power value for the first polarization p1 is B1 and the quantified power value for the second polarization p2 is B3, the UE can determine that the reported value i3= [0, 2] .
[0072] In some implementations, the same beam, as described herein, can be selected for different polarizations. In such implementations, the codebook indexes, e.g., i1, 1, i1, 2 for layer 1 or i1, 1, i1, 2, i1, 3 for layer 2 / 3 / 4, can be included in each PMI value to represent / indicate the selected beam indexes. In some implementations, three codebook indexes can be the same for different polarizations.
[0073] In some implementations, there may be power differences among different polarizations. For example, for different polarizations, different beam indexes can be considered. In this regard, the existing codebook indexes (e.g., i1, 1, i1, 2 for layer 1, or i1, 1, i1, 2, i1, 3 for layer 2 / 3 / 4) can be used for one polarization. In some implementations, one or more new parameters / codebook indexes can be added to each PMI value to be used for other / different polarizations. For instance, parameter i1, 4 can be used to represent / indicate the selected beam indexes for one dimension. Parameter i1, 5 can be used to represent / indicate the selected beam indexes for other dimensions. Parameter i1, 6 can be used to represent the orthogonal beam selection. In some implementations, if different beam indexes are selected for different polarizations, the existing codebook index i2 used to represent / indicate the phase adjustment for different polarizations may not be included in each PMI value. In some implementations, the value range of one or more newly added parameters can follow the existing specification.
