The present application claims the priority to Chinese Patent Application No. 202210339010.2, titled “USER EQUIPMENT, ELECTRONIC DEVICE, WIRELESS COMMUNICATION METHOD, AND STORAGE MEDIUM”, filed on Apr. 1, 2022 with the China National Intellectual Property Administration, which is incorporated herein by reference in its entirety.
The present disclosure generally relates to the field of wireless communications, and in particular to user equipment, an electronic device, a wireless communication method and a computer-readable storage medium. More specifically, the present disclosure relates to user equipment in a wireless communication system, an electronic apparatus serving as network side apparatus in a wireless communication system, a wireless communication method performed by user equipment in a wireless communication system, a wireless communication method performed by network side apparatus in a wireless communication system, and a computer-readable storage medium.
User equipment may be equipped with multiple antenna panels, abbreviated as panels, to cover multiple different directions. For example, each panel of the user equipment faces towards one direction and sends one or more beams. The user equipment may report a plurality of panels of the user equipment by using a user capability value set (UE capability value set) to network side apparatus, and each user capability value set corresponding to one panel. The user capability value set may include one or more user capability values. In the existing protocol, user equipment is not allowed to report two user capability value sets with a same user capability value. That is, if the user equipment has two panels and the user capability values in the user capability value sets of the two panels are the same, the user equipment is not allowed to report both panels to the network side apparatus simultaneously, that is, the network side apparatus fails to schedule the two panels simultaneously. As a result, application scenarios of scheduling a plurality of panels in the uplink transmission are greatly limited.
In addition, in the existing protocol, in a scenario where the user equipment is equipped with multiple antenna panels, it is not determined whether and how the network side apparatus sends feedback information after the user equipment reports beam quality information to the network side apparatus. Furthermore, how to perform uplink scheduling is also a technical problem to be solved if it is determined that the network side apparatus schedules a plurality of panels for uplink transmission of the user equipment.
Therefore, it is required to provide a technical solution to optimize the uplink transmission process of a plurality of panels of the user equipment.
This summary section provides a general summary of the present disclosure, rather than a comprehensive disclosure of its full scope or its features.

As described above, in the existing protocol, user equipment is not allowed to report two user capability value sets with a same user capability value, which greatly limits the application scenarios of scheduling a plurality of panels in uplink transmission. In addition, which antenna panel or which parameters of the antenna panel is used as user capability values in the user capability value set is not specified in the existing protocol. In addition, in the existing protocol, it is not determined whether and how the network side apparatus sends feedback information after the user equipment reports beam quality information to network side apparatus.

For such a scenario, electronic apparatus in a wireless communication system, a wireless communication method performed by electronic apparatus in a wireless communication system, and a computer-readable storage medium are provided according to the present disclosure, to optimize an uplink transmission process of a plurality of panels of user equipment.
The wireless communication system according to the present disclosure may be a 5G NR communication system or a 6G or a higher-level communication system.
The network side apparatus according to the present disclosure may be base station equipment, for example, an eNB, or a gNB (a base station in a fifth generation communication system).
The user equipment according to the present disclosure may be a mobile terminal (such as a smartphone, a tablet personal computer (PC), a notebook PC, a portable game terminal, a portable/dongle type mobile router and a digital camera) or a vehicle-mounted terminal (such as a car navigation apparatus). The user equipment may also be implemented as a terminal (also referred to as a machine-type communication (MTC) terminal) that performs machine-to-machine (M2M) communication. Furthermore, the user equipment may be a wireless communication module (such as an integrated circuitry module including a single die) mounted on each of the terminals described above.

As shown in
Here, each unit of the user equipment 100 may be included in processing circuitry. It should be noted that the user equipment 100 may include one or more processing circuitry. Furthermore, the processing circuitry may include various discrete functional units to perform various different functions and/or operations. It should be noted that these functional units may be physical entities or logical entities, and units with different names may be implemented by the same physical entity.
According to the embodiment of the present disclosure, the generation unit 110 may generate panel information. Here, the panel information may include a user capability value set of each of a plurality of panels of the user equipment 100. Furthermore, user capability values (UE capability values) in user capability value sets of different panels are the same or different.
According to the embodiment of the present disclosure, the user equipment 100 may send the panel information to network side apparatus via the communication unit 120. The network side apparatus herein may be configured to provide service for the user equipment 100
It can be seen that in the user equipment 100 according to the embodiment of the present disclosure, in the reported panel information, the user capability values in user capability value sets of different panels are the same or different. That is, according to the present disclosure, the restriction on the user equipment that is not allowed to report two panels with the same user capability value is eliminated, that is, the restriction on uplink transmission of a plurality of panels is eliminated, so that the user equipment can report any panel, thereby optimizing the uplink transmission process of a plurality of panels of the user equipment.
According to the embodiment of the present disclosure, as shown in
According to the embodiment of the present disclosure, the intra-panel coherence type represents a coherence situation among multiple ports of a panel, the coherence situation among the multiple ports of the panel includes full coherence, partial coherence, and incoherence.
According to the embodiment of the present disclosure, in a case where any two SRS ports among all SRS ports of the panel are coherent, the coherence type determination unit 130 may determine that the intra-panel coherence type of the panel is full coherence. Here, two coherent SRS ports refer to that a phase difference between the two SRS ports is constant, and thus the two SRS ports may use a same precoding matrix. That is, in a case of full coherence, all SRS ports of the panel use a same precoding matrix. For example, a panel A includes 4 SRS ports numbered 1 to 4, and any two SRS ports among the 4 SRS ports are coherent, that is, the 4 SRS ports use a same precoding matrix a, and thus the intra-panel coherence type of the panel A is full coherence.
According to the embodiment of the present disclosure, in a case where any two SRS ports among all SRS ports of the panel are incoherent, the coherence type determination unit 130 may determine that the intra-panel coherence type of the panel is incoherence. Here, two incoherence SRS ports refers to that a phase difference between the two SRS ports is not constant, that is, the phase difference varies over time. Therefore, the two SRS ports use different precoding matrices. That is, in a case of incoherence, all SRS ports of the panel use different precoding matrices. For example, a panel B includes 4 SRS ports numbered 1 to 4, and any two SRS ports among the 4 SRS ports are incoherent, that is, the 4 SRS ports use different precoding matrices a, b, c, and d, and thus the intra-panel coherence type of the panel B is incoherence.
According to the embodiment of the present disclosure, in a case where a part of all SRS ports of the panel are coherent, the coherence type determination unit 130 may determine that the intra-panel coherence type of the panel is partial coherence. That is, in a case of partial coherence, a part of all the SRS ports of the panel use a same precoding matrix. For example, a panel C includes 4 SRS ports numbered 1 to 4, and ports 1 and 2 among the 4 SRS ports are coherent and use a same precoding matrix a, a port 3 uses a precoding matrix b, a port 4 uses a precoding matrix c, and thus the intra-panel coherence type of the panel C is partial coherence.
According to the embodiment of the present disclosure, in a case where multiple ports of the panel are partially coherent, the coherence situation among the multiple ports of the panel further includes partially coherent ports. For example, in a case where ports 1 and 2 of the panel C are coherent, the coherence situation among the multiple ports of the panel may further include information indicating the coherence of 1 and 2, that is, the user capability value includes not only information indicating partial coherence, but also the partially coherent ports of the panel.
According to the embodiment of the present disclosure, the user capability value may further include the number of SRS ports, that is, the generation unit 110 may determine the number of the SRS ports of the panel as one user capability value, to cause the user capability value to be included in the user capability value set of the panel. That is, the user capability value set of each panel may include two user capability values: the number of SRS ports; and the intra-panel coherence type.
According to the embodiment of the present disclosure, the user capability value set of each panel may include one or more user capability values. user capability values in user capability value sets of two panels are the same, which indicates that all user capability values in the user capability value sets of the two panels are the same. Otherwise, user capability values in the user capability value sets of the two panels are different. Furthermore, according to the embodiment of the present disclosure, in a case where the user capability values in the user capability value sets of the two panels are the same, it can also be said that the user capability value sets of the two panels are the same.
That is, in a case where the user capability value set of each panel includes the number of SRS ports and the intra-panel coherence type, and two user capability values, i.e., the number of SRS ports and the intra-panel coherence type of one panel are the same as the number of SRS ports and the intra-panel coherence type of another panel, respectively, the user capability value sets of the two panels are the same. Otherwise, the user capability value sets of the two panels are different. For example, the number of SRS ports of the panel D is the same as the number of SRS ports of the panel E, the intra-panel coherence type of the panel D is partial coherence, where ports 1 and 2 are coherent, ports 3 and 4 are coherent, and the intra-panel coherence type of the panel E is partial coherence, where ports 1 and 4 are coherent, and ports 2 and 3 are coherent, and thus the user capability value set of the panel D is different from the user capability value set of the panel E. For example, if the number of SRS ports of a panel F is the same as the number of SRS ports of a panel G, the intra-panel coherence type of the panel F is full coherence, and the intra-panel coherence type of the panel G is full coherence, the user capability value set of the panel F is the same as the user capability value set of the panel G.
As described above, according to the embodiment of the present disclosure, the number of SRS ports of the panel and/or intra-panel coherence type of the panel may serve as user capability value, to cause the number of SRS ports of the panel and/or intra-panel coherence type of the panel to be included in the user capability value set of the panel. That is, two parameters that may serve as user capability value are defined in the present disclosure.
According to the embodiment of the present disclosure, after determining the user capability value set of each of all the panels of the user equipment 100 as described above, the generation unit 110 may control the user capability value set of each panel to be included in the panel information.
It can be seen that according to the embodiment of the present disclosure, regardless of whether the user capability value sets are the same, the user equipment may report the panel to the network side apparatus, that is, there is no restriction on scheduling a plurality of panels at the network side.
According to the embodiment of the present disclosure, after reporting the panel information, the user equipment 100 may receive RRC configuration information from the network side apparatus via the communication unit 120.
According to the embodiment of the present disclosure, as shown in
Parameters representing the channel quality is not limited in the present disclosure. For example, L1-RSRP (Lay 1-Reference Signal Receiving Power) or L1-SINR (Lay 1-Signal to Interference plus Noise Ratio) may be used to represent the channel quality of each beam.
According to the embodiment of the present disclosure, as shown in
According to the embodiment of the present disclosure, the generation unit 110 may further generate beam quality information for each panel. The beam quality information includes a preferred beam of the panel, so that the user equipment 100 can send the beam quality information to the network side apparatus via the communication unit 120.
According to the embodiment of the present disclosure, the preferred beam of the panel may be represented by panel indication information and beam indication information. Furthermore, since the panel and the user capability value set are in one-to-one correspondence, the panel indication information may be represented by identification information of the user capability value set (UE capability value set ID). In addition, since a downlink reference signal of the network side apparatus and the beam are in one-to-one correspondence, the beam indication information may be represented by CRI (CSI-RS resource indicator) or SSBRI (SSB (Synchronization Signal block) resource indicator). That is, the beam quality information of each panel may include the panel indication information and the beam indication information.
According to the embodiment of the present disclosure, the coherence type determination unit 130 may further determine an inter-panel coherence type of each panel, and the generation unit 110 may control the inter-panel coherence type to be included in the beam quality information.
According to the embodiment of the present disclosure, the inter-panel coherence type of the panel may represent a coherence situation between the panel and other panels. The coherence situation between the panel and other panels includes incoherence and coherence.
According to the embodiment of the present disclosure, if an intra-panel coherence type of a panel X is full coherence, an intra-panel coherence type of a panel Y is full coherence, and a phase difference between the various ports of the panel X is constant and a phase difference between the various ports of the panel Y is constant, the inter-panel coherence type of the panel X is coherence, and the inter-panel coherence type of the panel Y is coherence. In such case, various ports of the panel X and various ports of the panel Y may use a same precoding matrix.
For each panel, the coherence type determination unit 130 may determine whether the user equipment 100 includes other panel coherent with the panel. If there is no other panel coherent with the panel, the inter-panel coherence type of the panel is incoherence. If there is other panel coherent with the panel, the inter-panel coherence type of the panel is coherence. Furthermore, in a case where there is other panel coherent with the panel, the coherence situation between the panel and other panels further includes information of other panels coherent with the panel. For example, other panel may be represented by the identification information of the user capability value set. For example, if the panel X is coherent with the panel Y, the inter-panel coherence type of the panel X is coherence, and the inter-panel coherence type of the panel X includes information of the panel Y. The inter-panel coherence type of the panel Y is coherence, and the inter-panel coherence type of the panel Y includes information of the panel X.
According to the embodiment of the present disclosure, the generation unit 110 may further control the channel quality information of the preferred beam of the panel to be included in the beam quality information. The channel quality information includes but is not limited to L1-RSRP and L1-SINR.
As described above, the generation unit 110 may generate beam quality information for each panel. The beam quality information includes one or more of the following: the inter-panel coherence type of the panel; the preferred beam of the panel; and the channel quality information of the preferred beam of the panel.
As described above, according to the embodiment of the present disclosure, the user equipment 100 may report the inter-panel coherence type when reporting the beam quality information to the network side apparatus. In addition, the user equipment 100 may report the intra-panel coherence type when reporting the panel information to the network side apparatus. In this way, it is convenient for the network side apparatus to schedule panels for uplink transmission for the user equipment 100, and to determine the precoding matrix for each panel according to the intra-panel coherence type and the inter-panel coherence type of each panel.
According to the embodiment of the present disclosure, after sending the beam quality information to the network side apparatus, the user equipment 100 may receive feedback information for the beam quality information from the network side apparatus via the communication unit 120.
According to the embodiment of the present disclosure, as shown in
According to the embodiment of the present disclosure, the user equipment 100 may send the beam quality information by using PUCCH, such as UCI (Uplink Control Information) in PUCCH. In this case, the network side apparatus send the feedback information by using a DCI format 0 or a DCI format 2, so that the decoding unit 160 decodes the feedback information to determine ACK and NACK. In a case where the decoding unit 160 determines ACK, the user equipment 100 may determine that the network side apparatus has received the beam quality information. In a case where the decoding unit 160 determines NACK, the user equipment 100 may determine that no beam quality information is received by the network side apparatus. Two scenarios where the network side apparatus sends the feedback information by using the DCI format 0 and the DCI format 2 are described hereinafter in detail.
According to the embodiment of the present disclosure, the network side apparatus may send the feedback information by using the DCI format 0, such as a DCI format 0_1. Specifically, if the user equipment 100 requires information of the DCI format 0_1, the user equipment 100 may determine whether the information is feedback of PUSCH, PUCCH, or PUSCH and PUCCH based on a DFI (Downlink Feedback Information) flag, and then determine ACK or NACK based on HARQ-ACK bitmap of PUCCH or HARQ-ACK bitmap of PUSCH and PUCCH.
As described above, in a case where the user equipment 100 sends the beam quality information by using PUCCH, and the network side apparatus sends ACK or NACK, the network side apparatus may carry feedback information by reusing the DCI format 0_1, and the DCI format 0_1 is only slightly modified for carrying the feedback information.
According to the embodiment of the present disclosure, the network side apparatus may send the feedback information by using the DCI format 2, such as DCI format 2_x. Specifically, after the user equipment 100 acquires the information of the DCI format 2_x, based on PUCCH resources of sending the beam quality information by that the user equipment 100, the feedback information of the user equipment 100 may be determined from HARQ-ACK codebook for all the PUCCH resources, thereby determining ACK or NACK.
As described above, in a case where the user equipment 100 sends the beam quality information by using PUCCH, and the network side apparatus sends ACK or NACK, the network side apparatus may design a new DCI format 2_x to carry the feedback information.
Furthermore, the user equipment 100 may decode the DCI format by using RNTI (Radio Network Temporary Identity) dedicated to the DCI format 2_x.
According to the embodiment of the present disclosure, the user equipment 100 may send the beam quality information by using PUCCH, such as UCI (Uplink Control Information) in PUCCH. In this case, the network side apparatus may send the feedback information by using the DCI format 1, such as a DCI format 1_1 and a DCI format 1_2, so that the decoding unit 160 decodes the feedback information to determine the NACK. In a case where the decoding unit 160 determines NACK, the user equipment 100 may determine that no beam quality information is received by the network side apparatus. In a case where no NACK is received by the user equipment 100, the user equipment 100 may determine that the network side apparatus has received the beam quality information. In this way, the network side apparatus can only provide feedback on NACK, greatly reducing signaling overhead. Two scenarios where the network side apparatus sends the feedback information by using the DCI format 1_1 and the DCI format 1_2 are described hereinafter in detail.
According to the embodiment of the present disclosure, the network side apparatus may represent NACK feedback information by using a specific value of one or more fields in the DCI format 1_1. For example, the network side apparatus may represent NACK by using a specific value of one or more of a RV (Redundancy Version) field, an MCS (Modulation and Coding Scheme) field, and an FDRA (Frequency Domain Resource Assignment) field. As a non-limiting example, if the user equipment 100 determines that all values of the RV field are 1, all values of the MCS field are 1, and all values of the FDRA field are 0 based on the DCI format 1_1, the user equipment 100 may determine NACK, that is, no beam quality information is received by the network side apparatus. Otherwise, the user equipment 100 determines that the network side apparatus has received the beam quality information.
According to the embodiment of the present disclosure, the network side apparatus may represent NACK feedback information by using a specific value of one or more fields in DCI format 1_2. For example, the network side apparatus may represent NACK by using one or more specific values of the RV (Redundancy Version) field, the MCS (Modulation and Coding Scheme) field, and the FDRA (Frequency Domain Resource Assignment) field. As a non-limiting example, if the user equipment 10 determines that all values of the RV field are 1, all values of the MCS field are 1, and all values of the FDRA field are 0 based on the DCI format 1_2, the user equipment 100 may determine NACK, that is, no beam quality information is received by the network side apparatus. Otherwise, the user equipment 100 determines that the network side apparatus has received the beam quality information.
It should be noted that although the above embodiment in which the NACK information is indicated by using all values of the RV field being 1, all values of the MCS field being 1, and all values of the FDRA field being 0 is described, the embodiment is not restrictive. The network side apparatus may represent NACK by using other combinations of fields and other specific values of fields.
As described above, according to the embodiment of the present disclosure, in a case where the user equipment 100 sends the beam quality information by using PUCCH, and the network side apparatus only feedbacks NACK but does not feedback ACK, the network side apparatus may carry feedback information by reusing the DCI format 1.
According to the embodiment of the present disclosure, the user equipment 100 may send the beam quality information by using PUSCH, such as UCI or MAC CE in PUSCH. In this case, the network side apparatus may send feedback information by using the DCI format 0, such as DCI format 0_0 and the DCI format 0_1, so that the decoding unit 160 decodes the feedback information to determine the feedback information.
Specifically, the network side apparatus may represent ACK or NACK by using content of a NDI (New Data Indicator) field in uplink grant in the DCI format 0_0 or the DCI format 0_1. If the user equipment 100 receives the DCI format 0_0 or the DCI format 0_1, the user equipment 100 may determine whether the network side apparatus has received the beam quality information based on the value of the NDI field. For example, if the value of the NDI field is 1, it indicates an ACK message, that is, the network side apparatus has received the beam quality information. If the value of the NDI field is 0, it indicates an NACK message, that is, no beam quality information is received by the network side apparatus. Furthermore, the user equipment 100 may determine an NDI corresponding to the sent beam quality information based on the HARQ process identification information (HARQ process ID).
As described above, according to the embodiment of the present disclosure, in a case where the user equipment 100 sends the beam quality information by using PUSCH, the network side apparatus may carry feedback information via the identification information and the NDI field of the HARQ process in the DCI format 0.
According to the embodiment of the present disclosure, in a case where the user equipment 100 determines that no beam quality information is received by the network side apparatus, the user equipment 100 may resend the beam quality information.
As described above, the network side apparatus is required to provide feedback on the beam quality information sent by the user equipment 100 in the present disclosure. Furthermore, details of sending the feedback information by the network side apparatus are provided according to the present disclosure, so as to improve the reliability of the beam quality information.
According to the embodiment of the present disclosure, the user equipment 100 may further receive uplink scheduling information from the network side apparatus via the communication unit 120. For example, the user equipment 100 may receive uplink scheduling information based on the DCI format 0.
According to the embodiment of the present disclosure, the uplink scheduling information may include multiple SRIs (SRS Resource Indicators). As shown in
According to the embodiment of the present disclosure, the SRI may be used to indicate one SRS Resource in one SRS Resource Set, and the SRS Resource has a one-to-one correspondence with the uplink beam, and thus may be used to indicate a specific beam of the user equipment 100, that is, to indicate a specific panel of the user equipment 100. That is, the panel determination unit 170 may determine one panel based on each SRI, thereby determining a plurality of panels based on the multiple SRIs.
According to the embodiment of the present disclosure, the uplink scheduling information may also include an SRI, and the panel determination unit 170 is configured to determine a plurality of panels for uplink transmission based on one SRI in the uplink scheduling information.
According to the embodiment of the present disclosure, a mapping relationship between a beam combination and the SRI may be preset between the user equipment 100 and the network side apparatus. That is, various combinations of beams on different panels may be listed, and each combination has a mapping relationship with an SRI. In this way, the user equipment 100 may determine the beam combination based on one SRI in the uplink scheduling information, that is, determine multiple SRS resources in multiple SRS resource sets, thereby determining multiple beams and determining a panel where the multiple beams are located.
It can be seen that the user equipment 100 may determine multiple beams on a plurality of panels scheduled by the network side apparatus based on uplink scheduling information from the network side apparatus.
According to the embodiment of the present disclosure, the uplink scheduling information may further include TPMI (Transmission Precoder Matrix Index). As shown in
According to the embodiment of the present disclosure, in a case where the uplink scheduling information includes one TPMI, it indicates that a plurality of panels scheduled by the network side apparatus are coherent, and thus the plurality of panels may use a same precoding matrix. Therefore, the precoding matrix determination unit 180 may determine the precoding matrix indicated by the TPMI as the precoding matrix for a plurality of panels.
According to the embodiment of the present disclosure, in a case where the uplink scheduling information includes multiple TPMIs, it indicates that a plurality of panels scheduled by the network side apparatus are incoherent, and thus the plurality of panels may use different precoding matrices. Furthermore, the precoding matrix determination unit 180 may further determine the number of the precoding matrices for each panel, i.e., the number of the TPMI, based on the intra-panel coherence type of each scheduled panel. That is, in a case where the intra-panel coherence type is full coherence, all ports of the panel use a same precoding matrix, that is, the number of the TPMI is 1. In a case where the intra-panel coherence type is incoherence, all ports of the panel use different precoding matrices, that is, the number of the TPMI is the same as the number of ports. In a case where the intra-panel coherence type is partial coherence, coherent ports of the panel use a same precoding matrix, and incoherent ports use different precoding matrices.
For example, if the network side apparatus schedules a panel A and a panel B, and the panel A and the panel B are coherent, the user equipment 100 may determine one precoding matrix based on one TPMI, and both all ports of the panel A and all ports of the panel B use the precoding matrix. For example, if the network side apparatus schedules a panel C and a panel D, and the panel C and the panel D are incoherent, and the intra-panel coherence type of the panel C is full coherence, and the intra-panel coherence type of the panel D is incoherence, and the panel D has 2 ports, the user equipment may determine 3 precoding matrices based on 3 TPMIs, where all ports of the panel C use a precoding matrix 1, and 2 ports of the panel D use a precoding matrix 2 and a precoding matrix 3, respectively. For example, if the network side apparatus schedules a panel E and a panel F, the panel E and the panel F are incoherent, the intra-panel coherence type of the panel E is full coherence, the intra-panel coherence type of the panel F is partial coherence, and the panel F has four ports, where a port a and a port b are coherent, the user equipment may determine four precoding matrices based on four TPMIs, where all ports of the panel E use a precoding matrix 1, a port a and a port b of the panel F use a precoding matrix 2, a port c of the panel F uses a precoding matrix 3, and a port d of the panel F uses a precoding matrix 4.
Here, the network side apparatus may determine a coherence situation between various panels, for example, by using the inter-panel coherence type in the beam quality information, and determine a coherence situation between ports of each panel by using the intra-panel coherence type in the panel information, thereby determining the number of the precoding matrices required for each panel.

According to the embodiment of the present disclosure, in a case where the user equipment sends the beam quality information through PUCCH, the electronic apparatus 600 may carry the feedback information by using the DCI format 1, and the feedback information includes NACK.

That is, the electronic apparatus 600 may determine multiple beams on to-be-scheduled a plurality of panels. Since SRI has a one-to-one correspondence with the uplink beam, multiple beams may be indicated by multiple SRIs, thereby indicating a plurality of panels.
According to the embodiment of the present disclosure, the uplink scheduling information may include one SRI for indicating multiple beams on a plurality of panels scheduled for the user equipment. For example, a mapping relationship between a beam combination and the SRI may be preset between the user equipment 100 and the network side apparatus.

According to the embodiment of the present disclosure, in a case where a plurality of panels scheduled by electronic apparatus 600 are incoherent, the plurality of panels may use different precoding matrices. The precoding matrix determination unit 650 may further determine the number of the precoding matrices for each panel based on the intra-panel coherence type of each scheduled panel. That is, in a case where the intra-panel coherence type is full coherence, all ports of the panel use a same precoding matrix, that is, the number of the precoding matrix for the panel is 1. In a case where the intra-panel coherence type is incoherence, all ports of the panel use different precoding matrices, that is, the number of the precoding matrix for the panel is the same as the number of the ports. In a case where the intra-panel coherence type is partial coherence, coherent ports of the panel use a same precoding matrix, and incoherent ports use different precoding matrices. Furthermore, after the precoding matrix determination unit 650 determines the number of the precoding matrix for each panel, the generation unit 630 may indicate multiple precoding matrices with the number of TPMIs corresponding to the number of the precoding matrix, and control the multiple TPMIs to be included in the uplink scheduling information.
