Description

Beam indication method and apparatus, beam determination method and apparatus, and storage medium TECHNICAL FIELD

[0001] The present application relates to the field of wireless communication, in particular to a beam indication method and apparatus, a beam determination method and apparatus, and a storage medium. BACKGROUND

[0002] Distributed Multiple-Input Multiple-Output (Distributed MIMO) or Cell-Free Massive Multiple-Input Multiple-Output (CF-MIMO), Reconfigurable Intelligent Surface (RIS), and Network-Controlled Repeater (NCR) are gaining more and more attention as key technologies for Beyond 5th Generation / 6th Generation (B5G / 6G) mobile communication.

[0003] One feature of CF-MIMO is that the spatial distribution of Access Points (APs) in a given area is more dispersed than the centralized APs used by current New Radio (NR), and the number of APs is greater than that of User Equipment (UE), and multiple APs serve multiple UEs simultaneously through coherent transmission. RIS is composed of specific electromagnetic units, and through the application of control signals, it can dynamically regulate the spatial electromagnetic waves, thereby actively adjusting the wireless environment. RIS has the opportunity to break through the constraints of traditional wireless communication and bring a new paradigm to future mobile communication networks. To further improve the coverage effect of NR, NCR research began in 3rd Generation Partnership Project (3GPP) Release 18 (Rel-18). Based on traditional Radio Frequency Repeater (RF Repeater), NCR receives Side Control information (SCI) from the network side to achieve amplification and conversion in a more efficient manner. Compared with RF Repeater, NCR can avoid unnecessary noise amplification, obtain higher spatial directionality gain for transmission and reception, and simplify network integration deployment.

[0004] With the progress of technology, new devices are emerging with more powerful capabilities, and network nodes are being deployed more densely, leading to a growing demand for quality of service. Future wireless networks must achieve the goals of extremely high cellular system capacity, ensuring ultra-reliable transmission, supporting massive user access at the same time, and providing consistent user experience. Therefore, network deployment will face multiple challenges of cost, energy efficiency, performance, complexity, and scalability. Heterogeneous large-scale distributed network (Het-LDN) composed of network nodes with different capabilities provides an effective way to solve the above problems due to its low cost, low power consumption, high efficiency, easy deployment and expansion. However, related technical solutions do not support the multi-beam indication problem of Het-LDN. SUMMARY

[0025] The embodiments of the present application will be described below in conjunction with the accompanying drawings. The embodiments and features of the present application can be combined with each other if there is no conflict.

[0026] Figure 1 is a conceptual model of NCR node. As shown in Figure 1, each NCR node is composed of an NCR Mobile Termination (NCR-MT) and an NCR Forwarding (NCR-Fwd). The NCR-MT is a network entity with partial UE functionality, and it receives SCI from the next Generation Node B (gNB) through a control link. After receiving the SCI, the NCR-Fwd amplifies and forwards the transmission signals between the gNB and the UE through a backhaul link and an access link. The SCI is carried in the Radio Resource Control (RRC) or the Downlink Control Information (DCI). The SCI indicating the transmission beam of the NCR-Fwd is called beam indication. For the access link, the beam used by the NCR-Fwd is determined by a beam index. When the beam indication is informed, the beam index needs to be one-to-one corresponding to the time resource. The beam index can be configured to be periodic, semi-persistent, and aperiodic. The periodic and semi-persistent beam indication is determined by the RRC signaling. The activation or deactivation of the semi-persistent beam indication is determined by the Medium Access Control Control Element (MAC CE) signaling. The aperiodic beam indication is determined by the DCI. The physical beam of the NCR-Fwd depends on the implementation.

[0027] The DCI has multiple different uses, such as for scheduling the Physical Downlink Share Channel (PDSCH), scheduling the Physical Uplink Share Channel (PUSCH), and scheduling the Physical Downlink Share Channel (PDSCH), scheduling the sidelink, scheduling the multicast and broadcast service, and other uses. The DCI with different uses has different formats and contents.

[0028] A control resource set (CORESET) consists of one or more control channel elements (CCEs), which represent the time-frequency resource locations where the base station can transmit PDCCH. But the UE does not know which form of DCI the PDCCH carries, nor does it know which candidate CCE the DCI is transmitted on. The UE needs to blindly decode all possible DCI formats on different aggregation level CCEs. In order to reduce the number of blind decodes, the concept of search space (SS) is introduced. An SS is composed of a set of CCEs of a given aggregation level. The base station can configure one or more SSs for the UE.

[0029] The information elements of a CORESET include frequencyDomainResources, duration, precoderGranularity, tci-PresentInDCI, interleaverSize, pdcch-DMRS-ScramblingID, and reg-BundleSize. The information elements of an SS include monitoringSlotPeriodicityAndOffset, duration, monitoringSymbolsWithinSlot, aggregationLevel, and searchSpaceType.

[0030] RIS is also called intelligent reflecting surface (IRS) or software-defined metasurfaces (SDM) in some literature. RIS can be classified into different categories from different perspectives. First, according to whether there is a power amplifier, RIS can be divided into active RIS and passive RIS; second, according to the motion state, it can be divided into relatively stationary RIS and relatively moving RIS; third, according to the working mode, it can be divided into reflecting RIS, transmitting RIS, and simultaneously reflecting and transmitting RIS; fourth, according to the working mode, it can be divided into network-controlled RIS, network-assisted RIS, terminal-controlled RIS, terminal-assisted RIS, and independently deployed RIS; and finally, according to the purpose, it can be divided into coverage enhancement RIS, capacity enhancement RIS, perception enhancement RIS, and security enhancement RIS. Although the research on RIS is still ongoing in academia and industry, RIS has not been standardized, and it is not yet clear in which direction RIS will eventually evolve.

[0031] Considering that RIS can also serve as an Intelligent Repeater (IR), and NCR has been standardized in 3GPP-Rel-18, from the perspective of minimum standardization impact, RIS 1.0 version should take NCR as a template and consider the evolution direction of standardization in combination with the characteristics of RIS itself. Figure 2 is a conceptual model diagram of a RIS node. As shown in Figure 2, similar to NCR, a RIS node (RIS node) can be composed of a RIS mobile termination (RIS Mobile Termination, RIS-MT) and a RIS forwarding (RIS Forwarding, RIS-Fwd). Among them, RIS-MT is a network entity with partial UE functions, and RIS-MT receives SCI from gNB through Control link. After receiving SCI, RIS-Fwd amplifies and forwards the transmission signal between gNB and UE through Transmission link. By comparing Figure 1 and Figure 2, it can be found that compared with NCR, RIS-Fwd only has one transmission link because RIS has almost no delay characteristics. In addition, combined with the deployment scenarios and uses of RIS, the SCI controlled by gNB for RIS will be different from that for NCR. Since RIS and NCR are both network nodes with flexible beam steering capabilities and low cost, they occupy an important position in the research of 5G-Advanced and 6G.

[0032] In Het-LDN, at least two types of network nodes with different capabilities are included, the first type of node is a traditional AP with the strongest processing capability, and the second type of node is an IR with flexible beam steering capability. Among them, the AP includes various base stations (Base Station, BS), such as macro base stations, micro base stations, pico base stations, and flying base stations; the IR includes NCR and RIS. In addition, the BS is equivalent to gNB or Transmission and Reception Point (TRP) in some scenarios.

[0033] Het-LDN deployment needs to comprehensively consider the size of the deployment space, the number of active UEs, the quality of service (QoS) requirements, the deployment cost and other factors, and realize the optimal deployment of APs and IRs in limited space according to the corresponding criteria. FIG. 3 is a schematic diagram of the membership relationship between APs and IRs, and FIG. 4 is another schematic diagram of the membership relationship between APs and IRs. According to the number of APs in the deployment space, the membership relationship between APs and IRs at least includes: one AP governing all IRs in the space, as shown in FIG. 3; one AP governing part of the IRs, and the management levels of different APs are the same, as shown in FIG. 4. When there is only one AP in the deployment space, only this unique AP can overall control the transmission beams of multiple IRs to realize the global performance optimization of all deployment areas. When there are multiple different APs in the deployment space, each AP can overall control the transmission beams of multiple IRs under its jurisdiction, and there is no need for information interaction between APs to realize the local performance optimization of part of the deployment areas; or the multiple APs participating in cooperative transmission can interact with each other to realize the overall cooperative scheduling of all IRs in the deployment area.

[0034] FIG. 5 is a schematic diagram of Het-LDN deployment and service relationship. In FIG. 5, APs / IRs / UEs are all limited in a cuboid (corresponding to typical application scenarios such as indoor office, smart factory, etc.), APs are deployed on the ceiling and are equally spaced along the center of the ceiling, IRs are equally spaced along the four walls, and UEs are randomly distributed in the 2D space. The same type of network nodes have the same height, and the height of the AP is greater than the height of the IR, which is greater than the height of the UE. According to the actual situation, AP 1, AP 2 and AP 3 are configured to govern {IR 1, IR 2, IR 11, IR 12}, {IR 3, IR 4, IR 9, IR 10} and {IR 5, IR 6, IR 7, IR 8} respectively. At a certain moment, UE 1, UE 2 and UE 3 have data transmission requirements at the same time, according to the transmission strategy, it is determined that AP 1 serves UE 1 through the joint of IR 2 and IR 12, AP 2 serves UE 2 through the joint of IR 3 and IR 4, and AP 3 serves UE 3 through the joint of IR 5, IR 6 and IR 7.

[0035] In summary, Het-LDN needs to flexibly realize the simultaneous transmission beams of multiple different IRs to ensure the quality of service, but the related technical solutions cannot meet this demand.

[0036] FIG. 6 is a flowchart of a beam determination method provided by an embodiment of the present application. As shown in FIG. 6, the method provided by the embodiment includes:

[0037] S610, receiving first indication information, the first indication information including an information element for indicating the beam attribute in the multiple beam groups.

[0038] S620, receiving second indication information, the second indication information including information elements for indicating part of the plurality of beam groups and dynamic adjustment of the part of the plurality of beam groups.

[0039] The beam determination method provided by the embodiment is applied to an IR in Het-LDN, and the IR can be the NCR or the RIS. The IR determines a transmission beam according to information sent by an AP. The AP includes various types of B, such as a macro base station, a micro base station, a pico base station, and a flying base station. The IR can receive the information sent by the AP through DCI or RRC signaling.

[0040] The information received by the IR can be divided into two, namely first indication information and second indication information. The first indication information includes information elements for indicating beam properties in a plurality of beam groups, and the first indication information indicates beam properties in a plurality of beam groups formed by all beam groups that can be provided by the IR. The first indication information includes at least one information element for indicating beam properties in the plurality of beam groups. The second indication information includes information elements for indicating part of the plurality of beam groups and dynamic adjustment of the part of the plurality of beam groups, and the second indication information indicates part of the plurality of beam groups indicated by the first indication information. The second indication information also indicates dynamic adjustment of the part of the plurality of beam groups. The second indication information includes at least one information element for indicating beams in the part of the plurality of beam groups indicated by the first indication information, and at least one information element for dynamically adjusting the part of the plurality of beam groups. The first indication information can be received through first DCI or RRC signaling, and the second indication information can be received through second DCI or RRC signaling.

[0041] S630, determining first type beam group transmission beams and second type beam group transmission beams according to the first indication information and the second indication information, wherein the second type beam group transmission beams include part of the plurality of beam groups indicated by the second indication information and dynamically adjusted in the plurality of beam groups indicated by the first indication information, and the first type beam group transmission beams include remaining beam groups in the plurality of beam groups indicated by the first indication information, except for the part of the plurality of beam groups indicated by the second indication information.

[0042] After receiving the first indication information and the second indication information, the IR can determine the transmission beams according to the first indication information and the second indication information. The determined transmission beams include two types, which are respectively a first type of beam group transmission beam and a second type of beam group transmission beam. The first indication information can be used to determine a plurality of beam groups including a plurality of beams, and determine the related attributes of each beam group in the plurality of beam groups. The second indication information can be used to determine part of the beam groups in the plurality of beam groups, and determine the information elements for dynamically adjusting the determined part of the beam groups. Then, the first indication information and the second indication information are combined to determine the two types of transmission beam groups, which are referred to as the first type of beam group transmission beam and the second type of beam group transmission beam. The second type of beam group transmission beam is jointly indicated according to the first indication information and the second indication information. The attributes of the beams in the second type of beam group transmission beam are jointly indicated according to the first indication information and the second indication information. The second type of beam group transmission beam includes part of the beam groups in the plurality of beam groups indicated by the first indication information and dynamically adjusted by the second indication information. The first type of beam group transmission beam is composed of the remaining beam groups in the plurality of beam groups determined according to the first indication information, except for the part of the beam groups in the second type of beam group transmission beam. The attributes of the beams in the first type of beam group transmission beam are mainly determined according to the first indication information. The first type of beam group transmission beam includes the remaining beam groups in the plurality of beam groups indicated by the first indication information, except for the part of the beam groups indicated by the second indication information. The first indication information and the second indication information are used to jointly determine the transmission beams, which can be used to determine two types of beam groups with different attributes using less signaling overhead. The two-level indication information can be used to more flexibly implement the joint indication of the multiple beam groups.

[0043] The beam determination method provided in this embodiment can be used to jointly determine the first type of beam group transmission beam and the second type of beam group transmission beam after receiving the first indication information including the information elements for indicating the beam attributes in the plurality of beam groups and the second indication information including the information elements for indicating part of the beam groups in the plurality of beam groups and dynamically adjusting the part of the beam groups. The joint indication of the multiple beam groups can be implemented, and the signaling overhead is low. In addition, the two-level indication information can be used to more flexibly implement the joint indication of the multiple beam groups.

The first indication information can be sent through the first DCI or the RRC signaling, and the second indication information can be sent through the second DCI or the RRC signaling.

[0049] After sending the first indication information and the second indication information to the IR, the IR can determine the transmission beams according to the first indication information and the second indication information. The determined transmission beams include two types, which are respectively a first type of beam group transmission beam and a second type of beam group transmission beam. Wherein, according to the first indication information, a plurality of beam groups including a plurality of beams and the related attributes of each beam group in the plurality of beam groups can be determined. According to the second indication information, part of the beam groups in the plurality of beam groups and the information elements for dynamically adjusting the part of the beam groups can be determined. Then, the first indication information and the second indication information can be combined to determine the two types of transmission beam groups, which are referred to as the first type of beam group transmission beam and the second type of beam group transmission beam. The second type of beam group transmission beam is jointly indicated according to the first indication information and the second indication information, the attributes of the beams in the second type of beam group transmission beam are jointly indicated according to the first indication information and the second indication information, and the second type of beam group transmission beam includes part of the beam groups in the plurality of beam groups indicated by the second indication information and dynamically adjusted. The first type of beam group transmission beam is composed of the remaining beam groups in the plurality of beam groups except for the part of the beam groups in the second type of beam group transmission beam, the attributes of the beams in the first type of beam group transmission beam are mainly determined according to the first indication information, and the first type of beam group transmission beam includes the remaining beam groups in the beam groups indicated by the first indication information except for the part of the beam groups indicated by the second indication information. The first indication information and the second indication information are used to jointly determine the transmission beams, the two types of beam groups with different attributes can be determined using less signaling overhead, and the two-level indication information can be used to more flexibly implement the joint indication of multiple beam groups.

[0083] The indication information of the transmission beam at least includes first indication information and second indication information. Wherein, the first indication information includes one or more of beam group index information, time index information, transmission beam set mapping table, auxiliary reference information, common amplitude information, common phase information, common beam type information and common beam layout information; the second indication information includes one or more of time index subset information, beam index subset information, common beam off information, common amplitude adjustment information, common phase adjustment information, common beam type adjustment information and common beam layout adjustment information.

[0084] The following will be described respectively for the various types of information described above.

[0085] The beam group index information and the time index information are respectively composed of N beam group index elements and N time index elements, and the format of the beam group index information and the time index information can be:

[0086] bg_index_1,..., bg_index_i,..., bg_index_N

[0087] time_index_1,..., time_index_i,..., time_index_N

[0088] Each beam index element corresponds to each time index element one by one, that is, bg_index_i-->time_index_i. Where N is a positive integer, bg_index_i and time_index_i represent the i-th beam group index and the i-th time index respectively. time_index_i and bg_index_i can take non-negative integers. The values of time_index_1,..., time_index_i,..., time_index_N can be arranged in ascending order or descending order, or in random order. The values of bg_index_1,..., bg_index_i,..., bg_index_N are not strictly required. For example, at time_index_j and time_index_m, bg_index_j and bg_index_m take values J1 and M1 respectively, where m≠j. If J1=M1, it means that the beam group remains unchanged at two different times; otherwise, it means that the beam group switches at two different times.

[0089] The beam group index element indicates the index of the transmission beam of a plurality of simultaneously working different intelligent relays (RIS or NCR). The beam group index needs to be uniformly coded overall under different transmission beam combinations of intelligent relays under all possible preferred transmission combinations in a heterogeneous distributed network, and the mapping relationship between the beam group index and the beam group index and the transmission beam index set of the multi-intelligent relay is established, and is represented in the form of a transmission beam set mapping table. Taking multi-RIS cooperation as an example, the transmission beam set mapping table is as shown in Table 1:

[0090] Table 1 Transmission beam set mapping table

[0091] ris_L_beam_P represents the Pth transmission beam of the Lth RIS. Since the beam group index needs to consider all possible cooperative transmission RIS combinations and each RIS beam combination when coding, the implementation complexity and overall network performance need to be considered comprehensively, so the number of candidate beams of different RISes may be the same or different. The transmission beam set mapping table needs to be shared among all participating cooperative APs and IRs. IR can obtain the mapping relationship table through RRC signaling or other non-AP side network elements sent by the AP side. This embodiment only takes RIS as an example to illustrate the mapping relationship between the beam group index and the transmission beam index set of the multi-intelligent relay, which is also applicable to NCR, and will not be repeated here.

[0092] The auxiliary reference information can include beam amplitude information, beam phase information, beam type information, beam layout information, and physical beam association information. The auxiliary reference information such as the beam amplitude information, the beam layout information, the beam phase information, and the beam type information can be shared among different IRs or indicated for each IR respectively. The physical beam association information contains other key parameters for determining the physical beam of the IR. Due to the great difference in the number, density, and capability of network elements and the QoS requirement in the actual Het-LDN deployment scenario, different transmission schemes are required, and the auxiliary parameter information content of the indication scheme of the corresponding transmission beam is also different. The auxiliary reference information needs to be shared between each pair of APs and IRs participating in cooperative transmission. Different IRs can obtain different auxiliary reference information according to the capability of the IR and the actual transmission strategy. Alternatively, the auxiliary reference information can be obtained by an access point network element or a non-access point network element.

[0093] The common amplitude information represents the amplitude modulation parameter of the transmission beam of the different intelligent relays working simultaneously and associated with all the beam group index information in the time indicated by the time index information, which is determined by N1 bit parameters. N1 is an integer, which can be 1, 2, 3, 4, etc. For example, when N1 = 2, the mapping relationship between the common amplitude information and the amplitude modulation parameter is shown in Table 2:

[0094] Table 2 Mapping relationship between common amplitude information and amplitude modulation parameter

[0095] In Table 2, a uniform quantization scheme is given by 2bit information in [0, 1], and it is assumed that the value of the common amplitude information is positively correlated with the value of the amplitude modulation parameter. In addition, a non-uniform quantization scheme can also be adopted between the common amplitude information and the amplitude modulation parameter, and the value of the common amplitude information can also be inversely correlated with the value of the amplitude modulation parameter.

[0096] The common phase information represents the phase modulation parameter of the transmission beam of the different intelligent relays working simultaneously and associated with all the beam group index information in the time indicated by the time index information, which is determined by N2 bit parameters. N2 is an integer, which can be 1, 2, 3, 4, etc. For example, when N2 = 2, the mapping relationship between the common phase information and the phase modulation parameter is shown in Table 3:

[0097] Table 3 Mapping relationship between common phase information and phase modulation parameter

[0098] In Table 3, a uniform quantization scheme is given by 2bit information in [0, 2π], and it is assumed that the value of the common phase information is positively correlated with the value of the phase modulation parameter. In addition, a non-uniform quantization scheme can also be adopted between the common phase information and the phase modulation parameter, and the value of the common phase information can also be inversely correlated with the value of the phase modulation parameter.

[0099] The common beam type information represents the beam type of the transmission beam of the different smart relays working simultaneously associated with all the beam group index information in the time indicated by the time index information, which is indicated by N3 bit parameters. Wherein N3 is an integer, which can be 1, 2, 3, 4, etc.

[0100] When N3 = 1, the mapping relationship between the common beam type information and the beam type is as shown in Table 4:

[0101] Table 4 Mapping relationship table between common beam type information and beam type

[0102] When only 1 bit information is used to indicate the beam type, the beam type can be Wide_Beam (wide beam) or Narrow_Beam (narrow beam). In addition to indicating the beam type as wide or narrow, the common beam type information can further indicate the beam width information, such as indicating the beam width as 15° or 30° by 1 bit information in Table 5.

[0103] Table 5 Mapping relationship table between common beam type information and beam type

[0104] The common beam layout information represents the beam layout of the transmission beam of the different smart relays working simultaneously associated with all the beam group index information in the time indicated by the time index information, which is indicated by N4 bit parameters. Wherein N4 is an integer, which can be 1, 2, 3, 4, etc. The beam layout includes the indication information of the number of beams in the horizontal direction (Horizon) and the vertical direction (Vertical). As shown in Table 6, the beam layout is indicated by 3 bit information.

[0105] Table 6 Mapping relationship table between common beam layout information and beam layout

[0106] The time index subset information is composed of M time index elements, and its format is:

[0107] time_index_j1,..., time_index_ji,..., time_index_jM

[0108] M is a positive integer not more than N. The time index subset information is a subset of the time index information. The ordering of the elements in the time index subset information is consistent with the elements in the time index information.

[0109] The beam group index subset information is composed of M beam group index elements, and its format is:

[0110] bg_index_j1,..., bg_index_ji,..., bg_index_jM,

[0111] M is a positive integer not more than N. The beam group index subset information is a subset of the beam index information. Each element in the beam group index subset corresponds to one element in the time index subset information, i.e. bg_index_ji -> time_index_ji. Since the time index subset information is a subset of the time index information, by configuring different time index subsets in the second indication information, the content of the partial or all time associated transmission beam adjustment corresponding to the first indication information can be flexibly adjusted. Since the elements of the time index subset information are one-to-one associated with the elements of the beam group index subset, only one of the time index subset information and the beam group index subset information can be selected in the second indication information.

[0112] The common beam off information indicates that all the physical beams associated with the time index subset information are all turned off, and the information length is 1 bit, which can be represented by '0' or '1' to indicate the beam off. The common beam off information has no requirement on the content and format of the first indication information.

[0113] The common amplitude adjustment information indicates the amplitude adjustment amount of all the physical beams associated with the time index subset information, and the information length is M1 bits, M1 being a positive integer not more than N1. The amplitude adjustment parameters of all the physical beams associated with the time index subset information need to determine the final amplitude parameters of the beams by combining the common amplitude adjustment information and the common amplitude information, while the amplitude adjustment parameters of all the physical beams associated with the time index information except the time index subset information only determine the amplitude parameters of the beams according to the common amplitude information. For example, when N1 = 2 and M1 = 2, the mapping relationship between the common amplitude information and the amplitude adjustment parameter is shown in Table 2, and the mapping relationship between the common amplitude adjustment information and the cyclic shift amount of the amplitude adjustment parameter is shown in Table 7. For example, the common amplitude information and the common amplitude adjustment information are '01' and '00' respectively, and the amplitude adjustment parameter can be determined as '3 / 4' by combining Table 7 and Table 2; for another example, the common amplitude information and the common amplitude adjustment information are '10' and '01' respectively, and the amplitude adjustment parameter can be determined as '1 / 4' by combining Table 7 and Table 2. The common amplitude adjustment information and the cyclic shift amount of the amplitude adjustment parameter in Table 7 are completely positively correlated, and can also be inversely correlated or other functional relationship, and Table 7 is only exemplary.

[0114] The common amplitude adjustment information needs to include the common amplitude information in the first indication information, and the common amplitude adjustment information only has meaning when it is jointly indicated with the common amplitude information.

[0115] Table 7 Mapping relationship between common amplitude information and amplitude adjustment parameter

[0116] The common phase adjustment information indicates the phase adjustment amount of all physical beams associated with the time index subset information, and the information length is M2 bits, where M2 is a positive integer not exceeding N2. The amplitude modulation parameters of all physical beams associated with the time index subset information need to jointly determine the final phase parameters of the beams with the common phase adjustment information and the common phase information, while the phase modulation parameters of all physical beams associated with other information in the time index information only determine the phase parameters of the beams according to the common phase information. For example, when N2 = 2 and M2 = 2, the mapping relationship between the common phase information and the phase modulation parameters is shown in Table 3, and the mapping relationship between the common phase adjustment information and the phase modulation parameter cyclic shift amount is shown in Table 8. For example, the common phase information and the common phase adjustment information are '00' and '10' respectively, and the phase modulation parameter can be determined as 'П' in combination with Table 8 and Table 3. For another example, the common phase information and the common phase adjustment information are '10' and '11' respectively, and the phase modulation parameter can be determined as '3П / 2' in combination with Table 8 and Table 3. The common phase adjustment information and the phase modulation parameter cyclic shift amount in Table 8 are completely anti-correlated, and can also be positively correlated or other functional relationships, and Table 8 is only exemplary.

[0117] Table 8 Mapping relationship between common phase information and phase modulation parameter cyclic shift amount

[0118] The common phase adjustment information needs to include the common phase information in the first indication information, and the common phase adjustment information only has meaning when jointly indicated with the common phase information.

[0119] The common beam type adjustment information indicates the beam type adjustment amount of all physical beams associated with the time index subset information, and the information length is M3 bits, where M3 is a positive integer not exceeding N3. The beam types of all physical beams associated with the time index subset information need to jointly determine the final beam type with the common beam type adjustment information and the common beam type information, while the beam types of all physical beams associated with other information in the time index information only determine the beam type according to the common beam type information. For example, when N3 = 1 and M3 = 1, the mapping relationship between the common beam type information and the beam type is shown in Table 4, which can indicate the inversion of the beam type with 1 bit ('0' or '1'), i.e., from -> 'Narrow_Beam' or 'Narrow_Beam' -> 'Wide_Beam'. For another example, when N3 ≥ 1 and M3 = N3, the mapping relationship between the common beam type information and the beam type is shown in Table 4 or Table 5, which can indicate the beam type cyclic shift amount with M3 bits.

[0120] Specifically, when N3=2, M3=2, the mapping relationship between the common beam type information and the beam type and the mapping relationship between the common beam type adjustment information and the beam type cyclic shift amount are shown in Table 5 and Table 9 respectively. When the common beam type information and the common beam type adjustment information are '01' and '01' respectively, the beam type can be determined as 'Beam_Width_120°' in combination with Table 5 and Table 9. The common beam type adjustment information and the beam type cyclic shift amount in Table 9 are completely positively correlated, and can also be inversely correlated or other functional relationships, and Table 9 is only exemplary.

[0121] Table 9 Mapping relationship table between common beam type adjustment information and beam type cyclic shift amount

[0122] The common beam type adjustment information needs to include the common beam type information in the first indication information and the beam type indication method is consistent (wide or narrow type or specific beam width), and the common beam type adjustment information is only meaningful in combination with the common beam type information.

[0123] The common beam layout adjustment information indicates the beam layout adjustment amount of all physical beams associated with the time index subset information, and the information length is M4 bits, M4 being a positive integer not exceeding N4. The layout of all physical beams associated with the time index subset information needs to determine the final beam layout in combination with the common beam layout adjustment information and the common beam layout information, and the layout of all physical beams associated with the time index information except the time index subset information only determines the beam layout according to the common beam layout information.

[0124] For example, when N4=3, M4=2, the mapping relationship between the common beam layout information and the beam layout and the mapping relationship between the common beam layout adjustment information and the beam layout cyclic shift amount are shown in Table 6 and Table 10 respectively. When the common beam layout information and the common beam layout adjustment information are '001' and '10' respectively, the beam layout can be determined as 'Beam_Num_H_4_V_4' in combination with Table 6 and Table 10. The common beam layout adjustment information and the beam layout cyclic shift amount in Table 10 are completely positively correlated, and can also be inversely correlated or other functional relationships, and Table 10 is only exemplary.

[0125] Table 10 Mapping relationship table between common beam layout adjustment information and beam layout cyclic shift amount

[0126] The common beam layout adjustment information needs to include the common beam layout information in the first indication information, and the common beam layout adjustment information is only meaningful in combination with the common beam layout information.

That is, the first indication information indicates a beam group A according to the time index information, and the second indication information indicates a sub-beam group in the above beam group A according to the time index subset information, that is, the second type beam group. The other beam groups in the beam group A other than the second type beam group constitute the first type beam group.

The second indication information comprises time index subset information and common beam closing information. The auxiliary reference information comprises beam amplitude information, beam layout information, beam phase information, beam type information, and physical beam association information.

[0131] Since the elements in the time index information and the beam index information are one-to-one corresponding, the elements in the time index subset information and the beam index subset information are also one-to-one corresponding. Therefore, at least one of the time index information and the beam index information in the first indication information can be configured, and at least one of the time index subset information and the beam index subset information in the second indication information can be configured. The subsequent embodiments are described by taking the first indication information comprising the time index information and the second indication information comprising the time index subset information as an example.
