[0022] It should be understood that the specific embodiments described herein merely exemplify the present application and do not limit the present application. The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0023] 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 getting more and more attention as key technologies for B5G / 6G. A significant 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 in the current New Radio (NR), and the number of APs is more than the number of User Equipments (UEs), and multiple APs serve multiple UEs simultaneously through coherent transmission. In the future-oriented high-capacity dense application, a heterogeneous large-scale distributed network composed of a small number of traditional APs and a large number of IRs is a low-cost, high-performance, and flexible solution. Generally, at least two types of network nodes with different capabilities are included in Het-LDN, the first type of node is an 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 types of base stations (Base Station, BS), such as macro base stations, micro base stations, pico base stations, fly base stations, etc., in addition, in some scenarios, the BS can also be the next generation base station (the next Generation Node B, gNB) or a transmission and reception point (Transmission and Reception Point, TRP), etc., the type of AP is not limited in the embodiments of the present application. The IR can include NCR and RIS.

[0024] NCR is based on traditional Radio Frequency (RF) repeater, and implements amplification and conversion in a more efficient way by receiving network side Side Control information (SCI). Compared with RF repeater, NCR can avoid unnecessary noise amplification, obtain higher spatial directivity gain of transmission and reception, and simplify network integration deployment. Each NCR node can be composed of NCR-Mobile Termination (NCR-MT) and NCR-Forwarding (NCR-Fwd), and the conceptual model is shown in FIG. 1. Among them, NCR-MT is a network entity with part of the User Equipment (UE) function, and NCR-MT receives SCI from gNB through Control link. After receiving SCI, NCR-MT amplifies and forwards the transmission signal between gNB and UE through Backhaul link and Access link by NCR-Fwd.

[0025] SCI can be carried in Radio Resource Control (RRC) or Downlink Control Information (DCI). Among them, the SCI indicating the transmission beam of NCR-Fwd is called beamindication. For Access link, the beam used by NCR-Fwd is determined by "beamindex", and when beamindication is informed, beamindex needs to be one-to-one corresponding to time resource, and beamindex can be configured as periodic, semi-persistent and aperiodic. The periodic and semi-persistent beamindication is determined by RRC signaling. The activation or deactivation of semi-persistent beamindication is determined by Medium Access Control Control Element (MAC CE) signaling. The aperiodic beamindication is determined by DCI. The physical beam of NCR-Fwd depends on the implementation.

[0026] DCI has a variety of different uses, such as for scheduling a physical layer downlink shared channel (PDSCH), scheduling a physical layer uplink shared channel (PUSCH), scheduling a sidelink, scheduling a multicast and broadcast service, and other uses.

[0027] A RIS is composed of specific electromagnetic units, which can be dynamically controlled by applying control signals to achieve dynamic regulation of spatial electromagnetic waves, thereby actively adjusting the wireless environment. A RIS is also known as an intelligent reflecting surface (IRS) or a software-defined metasurface (SDM). From different perspectives, RIS can be classified into different categories. For example, according to whether there is a power amplifier, RIS can be divided into Active RIS and Passive RIS; according to the motion state, it can be divided into relatively stationary RIS and relatively moving RIS; for example, according to the working mode, it can be divided into reflective RIS, transmissive RIS, and reflective and transmissive RIS; according to the working mode, it can also be divided into network-controlled RIS, network-assisted RIS, terminal-controlled RIS, terminal-assisted RIS, and independently deployed RIS; according to the use, it can also be divided into coverage enhancement RIS, capacity enhancement RIS, perception enhancement RIS, and security enhancement RIS. Similar to NCR, a RIS node can be composed of a RIS-mobile termination (RIS-MT) and a RIS-forwarding (RIS-Fwd), and the conceptual model is shown in FIG. 2. Among them, the RIS-MT is a network entity with partial UE functions, and the RIS-MT receives the SCI from the gNB through the Control link. After receiving the SCI, the RIS-Fwd amplifies and forwards the transmission signal between the gNB and the UE through the Transmission link. Compared with NCR, since RIS has the feature of almost no delay, RIS-Fwd only has a transmission link. In addition, combined with the deployment scenarios and uses of RIS, the SCI of the gNB controlling the RIS will be different from that of the gNB controlling the NCR.

[0028] Het-LDN deployment needs to consider the size of the deployment space, the number of active UEs, QoS requirements, deployment costs and other factors, and realize the optimal deployment of APs and IRs in limited space according to the corresponding criteria. According to the number of APs in the deployment space, the membership relationship of APs and IRs includes at least: 1 AP governs all IRs in the space, as shown in FIG. 3; 1 AP governs part of the IRs, and the management levels of different APs are the same, as shown in FIG. 4. When there is only 1 AP in the deployment space, only this unique AP can overall control the transmission beams of multiple IRs to realize 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 exchange between APs to realize local performance optimization of part of the deployment area; or multiple APs participating in cooperative transmission can exchange information to realize overall coordinated scheduling of all IRs in the deployment area.

[0029] In one example, Het-LDN can be deployed in the manner shown in FIG. 5. In FIG. 5, APs / IRs / UEs are all defined 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 deployment space. The same type of network node has the same height, and the AP height>IR height>UE height. According to the actual situation, AP 1 governs {IR 1, IR 2, IR 11, IR 12}, AP 2 governs {IR 3, IR 4, IR 9, IR 10}, and AP 3 governs {IR 5, IR 6, IR 7, IR 8}. At a certain moment, UEs 1, 2 and 3 have simultaneous data transmission requirements, and according to the transmission strategy, 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.

[0030] Therefore, in Het-LDN or distributed network, how to flexibly jointly control multiple different IRs to transmit beams at the same time to ensure the quality of service is a technical problem that those skilled in the art urgently need to solve.

[0031] FIG. 6 is a flowchart of a method for determining a transmission beam according to an embodiment of the present application. The method is applied to an IR, as shown in FIG. 6, and can include the following steps:

[0032] S601, receiving beam indication information, the beam indication information being used to jointly indicate the beam information of multiple IRs working at the same time.

[0033] S602, determining a transmission beam according to the beam indication information.

[0034] The beam information of the multiple IRs participating in cooperative transmission is jointly indicated by the beam indication information, the multiple IRs determine the transmission beams based on the beam indication information, so that the multiple IRs transmit beams at the same time, and the network service quality is improved.

[0035] Optionally, the beam indication information can include at least one of the following: beam group index information, time index information, common amplitude information, common phase information, common beam type information, common beam layout information, auxiliary reference information, the identity of the IR, the first mapping relationship, and the second mapping relationship.

[0036] Specifically, the beam group index information includes N beam group index elements, and N is a positive integer. The beam group index element is used to indicate the index of the transmission beam of the multiple simultaneously working different IRs (such as RIS or NCR). The time index information includes N time index elements. The format of the beam group index information and the time index information can be:

[0037] bg_index_1,....,bg_index_i,...,bg_index_N;

[0038] time_index_1,....,time_index_i,...,time_index_N.

[0039] Wherein, the N time index elements correspond to the N beam group index elements one by one, that is, bg_index_i corresponds to time_index_i, which indicates that the i-th beam group index element is indicated at the i-th time index. 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 have no strict requirements. For example, at time_index_j and time_index_m, bg_index_j and bg_index_m take values J1 and M1 respectively. If J1=M1, it means that the beam groups of the multiple IRs participating in cooperative transmission remain unchanged at the two different time instants; otherwise, it means that the beam groups are switched at the two different time instants.

[0040] Optionally, the beam group index information and the time index information are determined by DCI signaling, that is, the beam group index information and the time index information can be carried in the DCI.

[0041] The first mapping relationship includes a mapping relationship between the beam group index element and a transmission beam set including transmission beams of multiple IRs participating in cooperative transmission. Exemplarily, taking multi-IR cooperation as an example, the first mapping relationship can be as shown in Table 1 below:

[0042] Table 1

[0043] wherein IR_L_beam_P represents the Pth transmission beam of the Lth IR. The beam group index element needs to be uniformly coded in the whole network considering all possible combinations of IRs participating in cooperative transmission and the beam combination of each IR in the heterogeneous distributed network, and therefore the construction of the first mapping relationship needs to comprehensively consider the implementation complexity and the overall network performance, and all possible scheduled IRs and beam conditions depend on the network planning and pre-scheduling algorithm. After the first mapping relationship is constructed, it needs to be tested offline for multiple times to meet the overall network performance, and the first mapping relationship is shared between the APs and the IRs participating in cooperative transmission after being tested offline for multiple times.

[0044] In addition to directly mapping the beam group index element to the transmission beam set of multiple IRs, the identification of the IR can also be introduced to establish a relationship among the beam group index element, the identification of the IR, and the transmission beam set of multiple IRs, that is, a second mapping relationship. Exemplarily, taking multi-IR cooperation as an example, the second mapping relationship can be as shown in Table 2 below:

[0045] Table 2

[0046] Without changing the content of the transmission beam set of multiple IRs, the introduction of the identification of the IR can reduce the overhead of the beam group index element to a certain extent. For example, in Table 1, 5 bits are needed to indicate the same transmission beam set, and after introducing the identification of the IR, in Table 2, the beam group index element only needs 3 bits to indicate the same transmission beam set. For example, when IR 1 and IR 2 both use their respective beam 1 for cooperative transmission, they share the beam group index 0. After receiving the beam group index, IR 1 and IR 2 still need to combine the identification of their respective exclusive IRs to determine the transmission beam index.

[0047] Optionally, the first mapping relationship, the second mapping relationship, and the identification of the IR can be acquired by an access point network element or a non-access point network element.

[0048] The common amplitude information is used to indicate an amplitude modulation parameter common to the transmission beams of multiple IRs associated with the beam group index information, and the length of the common amplitude information can be N1 bits, N1 being a positive integer, for example, the value of N1 can be 1, 2, 3, 4, etc. Taking N1 = 2 as an example, the mapping relationship between the common amplitude information and the amplitude modulation parameter can be as shown in Table 3 below:

[0049] Table 3

[0050] A uniform quantization scheme is exemplified in Table 3 by using 2-bit information between [0, 1], and it is assumed that the common amplitude information value is positively correlated with the amplitude modulation parameter value. In addition, a non-uniform quantization scheme can also be used between the common amplitude information and the amplitude modulation parameter, and the common amplitude information value can also be inversely correlated with the amplitude modulation parameter value, which is not limited in the embodiment.

[0051] The common phase information is used to indicate the phase modulation parameter common to the transmission beams of the multiple IRs associated with the beam group index information, and the length of the common phase information can be N2 bits, N2 being a positive integer, for example, the value of N2 can be 1, 2, 3, 4, etc. Taking N2 = 2 as an example, the mapping relationship between the common phase information and the phase modulation parameter is shown in Table 4 as follows:

[0052] Table 4

[0053] A uniform quantization scheme is exemplified in Table 4 by using 2-bit information between [0, 2П], and it is assumed that the common phase information value is positively correlated with the phase modulation parameter value. In addition, a non-uniform quantization scheme can also be used between the common phase information and the phase modulation parameter, and the common phase information value can also be inversely correlated with the phase modulation parameter value, which is not limited in the embodiment.

[0054] The common beam type information is used to indicate the beam type common to the transmission beams of the multiple IRs associated with the beam group index information, and the length of the common beam type information can be N3 bits, N3 being a positive integer, for example, the value of N3 can be 1, 2, 3, 4, etc. Taking N3 = 1 as an example, the mapping relationship between the common phase information and the phase modulation parameter is shown in Table 5 as follows:

[0055] Table 5

[0056] When only 1-bit information is used to indicate the beam type in Table 5, the beam type can be Wide_Beam (wide beam) or Narrow_Beam (narrow beam).

[0057] 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 1-bit information indicating the beam width as 15° or 30° in Table 6.

[0058] Table 6

[0059] To further improve the accuracy of the beam type representation, more quantization information can also be used. As shown in Table 7, the beam width is indicated by 2-bit information as 15°, 30°, 60° or 120°.

[0060] Table 7

[0061] The common beam layout information is used to indicate the transmission beam common to the plurality of IRs associated with the beam group index information. The length of the common beam layout information can be N4 bits, N4 being a positive integer, for example, the value of N4 can be 1, 2, 3, 4, etc. The common beam layout information can include indication information of the number of beams in the horizontal direction (Horizon) and the vertical direction (Vertical). As shown in Table 8, the beam layout is indicated by 3-bit information.

[0062] Table 8

[0063] The auxiliary reference information can include beam amplitude information, beam phase information, beam type information, beam layout information, and physical beam association information, wherein the auxiliary reference information such as beam amplitude information, beam layout information, beam phase information, and beam type information can be shared among different IRs, or can be indicated separately for each IR. 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 QoS requirements in the actual Het-LDN deployment scenario, different transmission schemes are needed, and the auxiliary parameter information content of the corresponding transmission beam indication scheme is also different. The auxiliary reference information needs to be shared between each pair of APs and IRs participating in cooperative transmission, and 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.

[0064] In one embodiment, the above-mentioned determination of the transmission beam according to the beam indication information can be: determining the transmission beam in a period of time indicated by the time index information according to the beam group index information, the first mapping relationship and the first auxiliary reference information.

[0065] Specifically, the above-mentioned beam group index information and time index information can be directly indicated by DCI, and the DCI signaling format can be: bg_index_1,....,bg_index_i,...,bg_index_N time_index_1,....,time_index_i,...,time_index_N.

[0066] Wherein, the beam group index information and the time index information respectively occupy Q1 bits and Q2 bits, Q1+Q2<=K0, the value of K0 is related to the maximum bit width of DCI, for example, K0 can take 128 bits, 256 bits or 512 bits, etc.

[0067] The first auxiliary reference information can include at least one of beam amplitude information, beam phase information, beam type information, beam layout information and physical beam association information, that is, the corresponding amplitude modulation parameters, phase modulation parameters, beam type, beam layout and physical beam association information can be obtained for IRs with different capabilities in combination with the capabilities of the IRs.

[0068] In the embodiment, after receiving the beam group index information and the time index information, the IR queries the first mapping relationship according to the beam group index value (or beam group index element) contained in the beam group index information, determines the index of the transmission beam in the time period indicated by the time index information, and further determines the parameters of the transmission beam, such as the amplitude modulation parameters, the phase modulation parameters, the beam width, the beam layout and the physical beam association information, in combination with the first auxiliary reference information. Taking Table 1 as an example, when the beam group index value is 0, IR1 and IR2 both determine to use their respective transmission beam “1” for cooperative transmission in combination with the beam group index value “0” and the first mapping relationship.

[0069] In one embodiment, the transmission beam determined according to the beam indication information can be determined according to the beam group index information, the second mapping relationship, the identity of the IR and the first auxiliary reference information in an embodiment.

[0070] Specifically, the beam group index information and the time index information can be directly indicated by DCI, and the DCI signaling format can be: bg_index_1,....,bg_index_i,...,bg_index_N time_index_1,....,time_index_i,...,time_index_N.

[0071] Wherein, the beam group index information and the time index information respectively occupy Q1 bits and Q2 bits, Q1+Q2<=K0, the value of K0 is related to the maximum bit width of DCI, for example, K0 can take 128 bits, 256 bits or 512 bits, etc.

[0072] The first auxiliary reference information can include at least one of beam amplitude information, beam phase information, beam type information, beam layout information and physical beam association information, that is, the corresponding amplitude modulation parameters, phase modulation parameters, beam type, beam layout and physical beam association information can be obtained for IRs with different capabilities in combination with the capabilities of the IRs.

[0073] In the embodiment, the IR queries the second mapping relationship according to the beam group index value (or the beam group index element) contained in the beam group index information and the identity of the IR assigned by the access point or the non-access point, determines the transmission beam in the period of time indicated by the time index information, and further determines the parameters of the transmission beam, such as the amplitude modulation parameter, the phase modulation parameter, the beam width, the beam layout and the physical beam association information of the transmission beam, in combination with the first auxiliary reference information. Taking Table 2 as an example, when the beam group index value is 0, IR1 and IR2 can determine the indexes of their respective transmission beams by the second mapping relationship in combination with the beam group index value "0" and the acquired self-exclusive ID identity, such as IR1 and IR2 respectively determining to use the transmission beam index "1" for cooperative transmission.

[0074] In one embodiment, the above determination of the transmission beam according to the beam indication information can be: determining the transmission beam in the period of time indicated by the time index information according to the beam group index information, the first mapping relationship, the common amplitude information and the second auxiliary reference information.

Optionally, the second auxiliary reference information is acquired by the access point network element or the non-access point network element, and the second auxiliary reference information includes at least one of the beam phase information, the beam type information, the beam layout information and the physical beam association information.

[0076] In this implementation, all the IRs participating in cooperative transmission use the same amplitude modulation parameter, and a small amount of indication information is added in the DCI signaling or the RRC signaling to realize the flexibility of the amplitude modulation of the transmission beam.

[0077] As an optional implementation, the transmission beams of the multiple IRs participating in cooperation are only indicated by the DCI signaling, and the DCI signaling format can be: bg_index_1,....,bg_index_i,...,bg_index_N time_index_1,....,time_index_i,...,time_index_N Common_amplitude_indication (common amplitude information).

[0078] Wherein, the beam group index information, the time index information and the common amplitude information respectively occupy Q1 bits, Q2 bits and N1 bits, Q1+Q2+N1<=K0, the value of K0 is related to the maximum bit width of DCI, and the value of K0 can be 128 bits, 256 bits or 512 bits.

[0079] As another optional implementation, the transmission beams of multiple IRs participating in cooperation can be indicated by RRC+DCI, and the DCI signaling format can be: bg_index_1,....,bg_index_i,...,bg_index_N time_index_1,....,time_index_i,...,time_index_N.

Optionally, the third auxiliary reference information is obtained through an access point network element or a non-access point network element, and the third auxiliary reference information includes at least one of beam amplitude information, beam type information, beam layout information and physical beam association information.
