[0093] Furthermore, each element, each row, or each column in the table of this disclosure can be implemented as an independent embodiment, and any combination of any element, any row, or any column can also be implemented as an independent embodiment.

[0094] In communication scenarios, high-frequency bands and massive MIMO (Massively Multi-Sized Antenna Arrays) are introduced to improve spectral efficiency. Massive MIMO can provide greater beamforming gain to compensate for the transmission losses caused by high-frequency bands.

[0095] For an antenna array (whose aperture is denoted as D), its electromagnetic (EM) field can be divided into a near field and a far field. As shown in Figure 1a, which is a schematic diagram of the near and far fields illustrating an exemplary embodiment of this disclosure, the boundary between the near and far fields is shown. This is called the Rayleigh distance. Here, λ represents the wavelength. The size of the near-field range depends on both the antenna aperture (D) and the wavelength (λ). If the terminal is in the far field, the electromagnetic wave received by the terminal may be a plane wave, and the beam directed at the terminal is a two-dimensional (2D) directional beam pointing towards the terminal. If the terminal is in the near field, then the electromagnetic wave received by the terminal may be a spherical wave, and the beam directed at the terminal is a three-dimensional (3D) beam surrounding the terminal. In Figure 1a, ∞ represents positive infinity.

[0096] Figure 1b is a schematic diagram illustrating far-field UE receiving electromagnetic waves according to an exemplary embodiment of this disclosure. As shown in Figure 1b, for a UE in the far field, the electromagnetic waves arriving at the UE from its different antenna ports or elements are plane waves, and the beam targeting the UE is a two-dimensional (2D) directional beam pointing towards the target UE. For any path in multipath propagation, the time and phase of arrival at the UE receiving antenna array are equally spaced.

[0097] Figure 1c is a schematic diagram illustrating near-field UE electromagnetic wave reception according to an exemplary embodiment of this disclosure. As shown in Figure 1c, if the UE is located in the near field, the electromagnetic wave received by the UE is a spherical wave, and the beam targeting the UE is a three-dimensional (3D) beam surrounding the target UE. For any path in multipath propagation, the time and phase of arrival at the UE receiving antenna array will no longer be equally spaced.

[0098] In Single-Transmission and Receiving Point (S-TRP) transmission, each Physical Downlink Shared Channel (PDSCH) or Physical Uplink Shared Channel (PUSCH) can correspond to a Transmission Configuration Indicator state (TCI state). However, in 6G VMI (Very Large Massive Array) antennas, considering near-field conditions, the optimal transmission beam for the terminal differs for different antenna array elements within a single Transmission and Receiving Point (TRP). Configuring the TCI state corresponding to each channel is a problem that needs to be addressed. The optimal transmission beam can be understood as the transmission beam with the best quality. The channel can be, for example, PDCCH, PUCCH, PDSCH, PUSCH, etc., but is not limited to these.

[0099] Therefore, this disclosure provides a communication method in which a terminal receives first information sent by a network device to determine multiple beams corresponding to a channel and / or a reference signal, and / or to determine multiple beams corresponding to one or more first ports of the channel and / or the reference signal, thereby achieving accurate and efficient beam determination, reducing signaling overhead, and improving transmission performance.

[0100] Figure 1d is a schematic diagram of a communication system architecture according to an embodiment of the present disclosure.

[0101] As shown in Figure 1d, the communication system 100 includes a terminal 101 and a network device 102.

[0105] In some embodiments, the technical solutions of this disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within access network devices involved in the embodiments of this disclosure can be transformed into internal interfaces of Open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0106] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0107] In some embodiments, a core network device may be a single device comprising one or more network elements, or it may be multiple devices or a group of devices, each comprising all or part of the aforementioned one or more network elements. Network elements may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), or a Next Generation Core (NGC).

[0108] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0109] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1d, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1d are illustrative. The communication system may include all or some of the main bodies in FIG1d, or may include other main bodies outside of FIG1d.

[0111] Figure 2 is a schematic diagram of a communication method interaction according to an embodiment of the present disclosure. As shown in Figure 2, this embodiment of the present disclosure relates to a communication method for a communication system 100, the method including:

[0112] In step S2101, network device 102 sends first information to terminal 101.

[0113] In some embodiments, terminal 101 receives first information sent by network device 102.

[0114] In some embodiments, the name of the first information is not limited, and it may be, for example, "first instruction information".

[0115] In some embodiments, the first information is used to determine multiple beams corresponding to the channel and / or the reference signal, and / or, the first information is used to determine multiple beams corresponding to one or more first ports of the channel and / or the reference signal.

[0116] Optionally, the first information can be used to determine multiple beams corresponding to the channel. These multiple beams can be understood as the multiple beams used to transmit or receive data and signals on the channel. For example, a terminal can use the determined multiple beams to transmit and / or receive signals, data, etc., on the channel.

[0117] Optionally, the first information can be used to determine multiple beams corresponding to the reference signal. These multiple beams can be understood as multiple beams used to transmit and / or receive the reference signal. For example, the terminal can use the determined multiple beams to transmit and / or receive the reference signal.

[0118] Optionally, the first information can be used to determine multiple beams corresponding to a first port of the channel. The multiple beams corresponding to the first port can be understood as multiple beams used to transmit and / or receive signals and data at the first port. For example, a terminal can use the determined multiple beams to transmit and / or receive signals, data, etc., at a first port of the channel.

[0119] Optionally, the first information can be used to determine multiple beams corresponding to multiple first ports of the channel, wherein each first port may correspond to one or more beams. The multiple beams corresponding to the first ports can be understood as multiple beams used to transmit and / or receive signals and data at the first ports. For example, a terminal can use the determined multiple beams to transmit and / or receive signals, data, etc., at the multiple first ports of the channel.

[0120] Optionally, the first information can be used to determine multiple beams corresponding to a first port of the reference signal. The multiple beams corresponding to the first port can be understood as multiple beams used to transmit and / or receive the reference signal at the first port. For example, a terminal can use the determined multiple beams to transmit and / or receive the reference signal at a first port.

[0121] Optionally, the first information can be used to determine multiple beams corresponding to multiple first ports of the reference signal, wherein each first port corresponds to one or more beams. The multiple beams corresponding to the first ports can be understood as multiple beams used to transmit and / or receive the reference signal at the first ports. For example, a terminal can use the determined multiple beams to transmit and / or receive the reference signal on multiple first ports.

[0122] In some embodiments, terminal 101 may be a near-field terminal, but is not limited thereto. The meaning of near-field terminal can be referred to in the above embodiments, and will not be repeated here. It is understood that for a near-field terminal, the optimal transmit beam for the terminal may be different for different ports of a TRP of a network device. Therefore, the terminal can determine multiple beams through the first information, thereby using accurate beams to transmit and / or receive channels, transmit and / or receive reference signals, etc., to improve transmission performance.

[0123] In some embodiments, the channel and / or reference signal includes at least one of the following: the Physical Downlink Control Channel (PDCCH) and / or the Demodulation Reference Signal (DMRS) of the PDCCH; the Physical Downlink Shared Channel (PDSCH) and / or the DMRS of the PDSCH; the Physical Uplink Control Channel (PUCCH) and / or the DMRS of the PUCCH; and the Physical Uplink Shared Channel (PUSCH) and / or the DMRS of the PUSCH.

[0124] Optionally, the channel can be a PDCCH, and the reference signal can be the DMRS of the PDCCH. The DMRS can be used for channel estimation; for example, the DMRS of the PDCCH can be understood as a DMRS used to estimate the channel state corresponding to the PDCCH. That is, the DMRS of the PDCCH can be used to estimate the channel state corresponding to that PDCCH. For example, the first information can be used to determine multiple beams corresponding to the PDCCH and / or the DMRS of the PDCCH, and / or the first information can be used to determine multiple beams corresponding to one or more first ports of the PDCCH and / or the PDCCH.

[0125] Optionally, the channel can be a PDSCH, and the reference signal can be the DMRS of the PDSCH. The DMRS can be used for channel estimation; for example, the DMRS of the PDSCH can be understood as the DMRS used to estimate the channel state corresponding to the PDSCH. That is, the DMRS of the PDSCH can be used to estimate the channel state corresponding to that PDSCH. The first information can be used to determine multiple beams corresponding to the PDSCH and / or the DMRS of the PDSCH, and / or, the first information can be used to determine multiple beams corresponding to one or more first ports of the PDSCH and / or the PDSCH.

[0126] Optionally, the channel can be a PUCCH, and the reference signal can be the DMRS of the PUCCH. The DMRS can be used for channel estimation; for example, the DMRS of the PUCCH can be understood as a DMRS used to estimate the channel state corresponding to the PUCCH. That is, the DMRS of the PUCCH can be used to estimate the channel state corresponding to that PUCCH. The first information can be used to determine multiple beams corresponding to the PUCCH and / or the DMRS of the PUCCH, and / or, the first information can be used to determine multiple beams corresponding to one or more first ports of the PUCCH and / or the PUCCH.

[0127] Optionally, the channel can be a PUSCH, and the reference signal can be the DMRS of the PUSCH. The DMRS can be used for channel estimation; for example, the DMRS of the PUSCH can be understood as a DMRS used to estimate the channel state corresponding to the PUSCH. That is, the DMRS of the PUSCH can be used to estimate the channel state corresponding to that PUSCH. The first information can be used to determine multiple beams corresponding to the PUSCH and / or the DMRS of the PUSCH, and / or the first information can be used to determine multiple beams corresponding to one or more first ports of the PUSCH.

[0128] In some embodiments, the first port may be a DMRS port, but is not limited thereto. Taking a DMRS port as an example, one or more first ports of a channel may be one or more DMRS ports corresponding to the channel, and one or more first ports of a reference signal may be one or more DMRS ports of the reference signal. A DMRS port can be understood as a port used to transmit DMRS. For example, the DMRS port of a channel transmits DMRS used to estimate the channel state corresponding to the channel. Exemplarily, the DMRS transmitted by the DMRS port of a PDCCH can be used to estimate the channel state corresponding to the PDCCH. Exemplarily, the DMRS transmitted by the DMRS port of a PDSCH can be used to estimate the channel state corresponding to the PDSCH. This disclosure does not provide examples one by one, but is not limited thereto. For another example, the reference signal is a DMRS, and the DMRS port of the reference signal transmits the reference signal. First information may be used to determine multiple beams corresponding to one or more DMRS ports of the channel and / or the reference signal. For example, the first information may be used to determine multiple beams corresponding to one or more DMRS ports of the channel. For another example, the first information may be used to determine multiple beams corresponding to one or more DMRS ports of the reference signal. For example, the first information can be used to determine multiple beams corresponding to one or more DMRS ports of the channel and the reference signal, respectively.

[0129] It is understood that the ports in the various embodiments of this disclosure can also be replaced by port groups, antenna arrays, antenna array groups, antenna elements, or antenna element groups, etc. A port group can be understood as a combination of ports containing at least two ports. An antenna array group can be understood as a combination of antenna arrays containing at least two antenna arrays. An antenna element group can be understood as a combination of antenna elements containing at least two antenna elements. For example, a first port can be replaced by a first port group, a first antenna array, a first antenna array group, a first antenna element, or a first antenna element group. Correspondingly, a DMRS port can be replaced by a DMRS group, a DMRS antenna array, a DMRS antenna array group, a DMRS antenna element, or a DMRS antenna element group.

[0130] In some embodiments, a beam can be referred to as quasi-co-location (QCL) Type D, spatial Rx parameter or spatial reception parameter, spatial Tx parameter or spatial transmission parameter, spatial setting, spatial relation info, spatial reception filter, spatial transmission filter, spatial domain filter, TCI state, indicated TCI state, joint TCI state, downlink TCI state, uplink TCI state, unified TCI state, common TCI state, etc.

[0131] In some embodiments, the first information may indicate multiple first identifiers, and each first identifier corresponds to a first reference signal resource, which is a single-port reference signal resource. That is, the first information may indicate multiple first identifiers so that the terminal can determine multiple beams based on the first reference signal resources corresponding to the multiple first identifiers. Here, a single-port reference signal resource can be understood as a reference signal resource transmitted only on one port, i.e., different ports transmit different reference signal resources.

[0132] In some embodiments, a first reference signal resource corresponding to one first identifier is used to determine one beam, and multiple first reference signal resources corresponding to multiple first identifiers can be used to determine multiple beams. Assume that first identifier #1 corresponds to first reference signal resource A, first identifier #2 corresponds to first reference signal resource B, and first identifier #3 corresponds to first reference signal resource C.

[0133] For example, if the first information indicates first identifier #1, first identifier #2, and first identifier #3, the terminal can determine beam A, which transmits or receives first reference signal resource A, as a beam corresponding to the channel and / or reference signal; beam B, which transmits or receives first reference signal resource B, as a beam corresponding to the channel and / or reference signal; and beam C, which transmits or receives first reference signal resource C, as a beam corresponding to the channel and / or reference signal. In other words, by determining beams A, B, and C as multiple beams corresponding to the channel and / or reference signal, the terminal can use beams A, B, and C to transmit and / or receive data, signals, etc., on the channel; or, the terminal can use beams A, B, and C to transmit and / or receive reference signals.

[0134] For example, if the first information indicates first identifier #1, first identifier #2, and first identifier #3, the terminal can determine beam A as one beam of a first port of the channel and / or reference signal. Beam B can be determined as another beam of the same first port of the channel and / or reference signal. Beam C can be determined as another beam of the same first port of the channel and / or reference signal. That is, beams A, B, and C are determined as multiple beams corresponding to a first port of the channel and / or reference signal.

[0135] For example, if the first information indicates first identifier #1, first identifier #2, and first identifier #3, the terminal can determine beam A as a beam for one first port of the channel and / or reference signal. Beam B can be determined as a beam for another first port of the channel and / or reference signal. Beam C can be determined as a beam for another first port of the channel and / or reference signal. That is, beams A, B, and C are determined as multiple beams corresponding to multiple first ports of the channel and / or reference signal, wherein each first port corresponds to one beam.

[0136] For example, if the first information indicates first identifier #1, first identifier #2, and first identifier #3, the terminal can determine beam A as a beam for one first port of the channel and / or reference signal. Beams B and C can be determined as beams for another first port of the channel and / or reference signal. That is, beams A, B, and C can be determined as multiple beams corresponding to multiple first ports of the channel and / or reference signal, where one first port corresponds to one beam, and another port corresponds to multiple beams.

[0137] For example, if there are more first identifiers, multiple beams corresponding to each first port can also be determined.

[0138] It is understandable that each first port can correspond to one or more beams, and the number of beams corresponding to different first ports can be the same or different.

[0139] In some embodiments, the first information may indicate a first identifier, and the first identifier corresponds to a second reference signal resource, which is a multi-port reference signal resource. That is, the first information may indicate a first identifier so that the terminal can determine multiple beams based on the second reference signal resource corresponding to the first identifier. Here, the multi-port reference signal resource can be understood as a reference signal resource transmitted on multiple ports, that is, multiple ports transmit the same reference signal resource.

[0140] In some embodiments, a second reference signal resource corresponding to a first identifier is used to determine multiple beams. One or more second ports of the second reference signal resource are used to determine one beam. Assuming the first identifier #1 corresponds to the second reference signal resource D, the second ports of the second reference signal resource D include second port D1, second port D2, second port D3, and second port D4.

[0141] For example, if a second port of the second reference signal resource can determine a beam, then multiple second ports of the second reference signal resource can be used to determine multiple beams. For instance, if the first information includes a first identifier #1, the terminal can determine beam D1, used for transmitting and / or receiving the second reference signal resource D at second port D1, as a beam corresponding to the channel and / or reference signal. Similarly, beam D2, used for transmitting and / or receiving the second reference signal resource D at second port D2, can be determined as a beam corresponding to the channel and / or reference signal. Likewise, beam D3, used for transmitting and / or receiving the second reference signal resource D at second port D3, can be determined as a beam corresponding to the channel and / or reference signal. Finally, beam D4, used for transmitting and / or receiving the second reference signal resource D at second port D4, can be determined as a beam corresponding to the channel and / or reference signal. In other words, beams D1, D2, D3, and D4 are designated as multiple beams corresponding to the channel and / or reference signal. The terminal can use beams D1, D2, D3, and D4 to transmit and / or receive data, signals, etc. on the channel, or the terminal can use beams D1, D2, D3, and D4 to transmit and / or receive the reference signal.

[0142] For example, if a second port of a second reference signal resource can define a beam, then multiple second ports of the second reference signal resource can be used to define multiple beams. For instance, if the first information includes a first identifier #1, the terminal can define beam D1 as a beam of a first port of the channel and / or reference signal. Beam D2 can be defined as another beam of the same first port of the channel and / or reference signal. Beam D3 can be defined as another beam of the same first port of the channel and / or reference signal. Beam D4 can be defined as another beam of the same first port of the channel and / or reference signal. That is, beams D1, D2, D3, and D4 are defined as multiple beams corresponding to a first port of the channel and / or reference signal.

[0143] For example, if a second port of the second reference signal resource can determine one beam, then multiple second ports of the second reference signal resource can be used to determine multiple beams. For instance, if the first information includes a first identifier #1, the terminal can determine beam D1 as a beam of one first port of the channel and / or reference signal. Beam D2 can be determined as a beam of another first port of the channel and / or reference signal. Beam D3 can be determined as a beam of another first port of the channel and / or reference signal. Beam D4 can be determined as a beam of another first port of the channel and / or reference signal. That is, beams D1, D2, D3, and D4 are determined as multiple beams corresponding to multiple first ports of the channel and / or reference signal, where each first port corresponds to one beam. It is understood that if the second reference signal resource has more second ports, multiple beams corresponding to each first port can also be determined; this disclosure does not provide examples of all such instances.

[0144] For example, if a second port of a second reference signal resource can define one beam, then multiple second ports of the second reference signal resource can be used to define multiple beams. For instance, if the first information includes a first identifier #1, the terminal can define beams D1 and D2 as two beams of one first port of the channel and / or reference signal. Beams D3 and D4 can be defined as two beams of another first port of the channel and / or reference signal. That is, each first port can correspond to multiple beams, and the number of beams corresponding to different first ports can be the same.

[0145] For example, if the second reference signal resource corresponds to more second ports, it can also be determined that each first port corresponds to multiple beams, and the number of beams corresponding to different first ports is different.

[0146] For example, if one second port of the second reference signal resource can define one beam, then multiple second ports of the second reference signal resource can be used to define multiple beams. For instance, if the first information includes a first identifier #1, the terminal can define beam D1 as two beams of one first port of the channel and / or reference signal. Beams D2, D3, and D4 can be defined as two beams of another first port of the channel and / or reference signal. That is, one first port corresponds to one beam, and another first port corresponds to multiple beams; the number of beams corresponding to different first ports can be different.

[0147] It is understandable that each first port can correspond to one or more beams, and the number of beams corresponding to different first ports can be the same or different.

[0148] For example, multiple second ports of the second reference signal resource can define a beam, and more second ports can define multiple beams. For instance, if the first information includes a first identifier #1, the terminal can determine the beam D5 used to transmit and / or receive the second reference signal resource D at second ports D1 and D2 as a beam corresponding to the channel and / or reference signal. That is, second ports D1 and D2 can correspond to the same beam D5, and the terminal can determine a beam based on multiple second ports of the second reference signal resource. Similarly, the terminal can determine the beam D6 used to transmit and / or receive the second reference signal resource D at second ports D3 and D4 as a beam corresponding to the channel and / or reference signal. That is, second ports D3 and D4 can correspond to the same beam D6, and the terminal can determine a beam based on multiple second ports of the second reference signal resource. In other words, the terminal can identify beams D5 and D6 as multiple beams corresponding to the channel and / or reference signal. The terminal can use beams D5 and D6 to send and / or receive data, signals, etc. on the channel, or the terminal can use beams D5 and D6 to send and / or receive reference signals.

[0149] For example, if multiple second ports of a second reference signal resource can define a beam, then more second ports can define multiple beams. For instance, if the first information includes a first identifier #1, the terminal can define beam D5 corresponding to second port D1 and second port D2 as a beam of a first port of the channel and / or reference signal. Beam D6 corresponding to second port D3 and second port D4 can be defined as another beam of the same first port. That is, beams D5 and D6 can be defined as multiple beams corresponding to a first port of the channel and / or reference signal.

[0150] For example, if multiple second ports of the second reference signal resource can define one beam, then more second ports can define multiple beams. For instance, if the first information includes a first identifier #1, the terminal can define beam D5 corresponding to second port D1 and second port D2 as a beam of one first port of the channel and / or reference signal. The beam D6 corresponding to second port D3 and second port D4 can be defined as a beam of another first port of the channel and / or reference signal. That is, beams D5 and D6 can be defined as multiple beams corresponding to multiple first ports of the channel and / or reference signal. Each first port corresponds to one beam. It is understood that if the second reference signal resource has more second ports, multiple beams corresponding to each first port can also be defined; this disclosure does not provide examples of all such instances.

[0151] In some embodiments, if the first information indicates a first identifier, and the first identifier corresponds to a second reference signal resource, since the second reference signal resource is a multi-port reference signal resource, the first information may also indicate a second identifier, which corresponds to a second port of the second reference signal resource. For example, among the multiple second ports of the second reference signal resource, only some of the beams corresponding to the second ports can be used to determine multiple beams corresponding to the channel and / or reference signal, or to determine multiple beams corresponding to one or more first ports of the channel and / or reference signal. Then, the first information can indicate a second identifier so that the terminal determines multiple beams based on the second port corresponding to the second identifier.

[0152] Optionally, if the first information only indicates the first identifier and not the second identifier, the terminal can determine multiple beams based on all the second ports of the second reference signal resource corresponding to the first identifier. For example, assuming the first identifier #1 corresponds to the second reference signal resource D, the second ports of the second reference signal resource D include second port D1, second port D2, second port D3, and second port D4. If the first information only indicates the first identifier #1, the terminal can determine beams D1, D2, D3, and D4 as multiple beams corresponding to the channel and / or reference signal, or as multiple beams corresponding to one or more first ports of the channel and / or reference signal. The description of beams D1, D2, D3, and D4 can be found in the above embodiments. For example, beam D1 is the beam used to transmit and / or receive the second reference signal resource D at the second port D1, which will not be elaborated further in this disclosure.

[0153] Optionally, if the first information indicates a first identifier and a second identifier, the terminal can determine multiple beams based on the second port corresponding to the second identifier among all the second ports of the second reference signal resource corresponding to the first identifier. For example, assuming that the first identifier #1 corresponds to the second reference signal resource D, the second ports of the second reference signal resource D include second port D1, second port D2, second port D3, and second port D4.

[0154] For example, if a second port of the second reference signal resource can define a beam, then multiple second ports of the second reference signal resource can be used to define multiple beams. For instance, if the first information includes a first identifier #1, a second identifier #1-1 corresponding to second port D1, and a second identifier #1-2 corresponding to second port D2, then the terminal can define beam D1, used for transmitting and / or receiving the second reference signal resource D at second port D1, as a beam corresponding to the channel and / or reference signal. Similarly, beam D2, used for transmitting and / or receiving the second reference signal resource D at second port D2, can be defined as a beam corresponding to the channel and / or reference signal. In other words, beams D1 and D2 can be defined as multiple beams corresponding to the channel and / or reference signal.

[0155] For example, if a second port of a second reference signal resource can define a beam, then multiple second ports of the second reference signal resource can be used to define multiple beams. For instance, if the first information includes a first identifier #1, second identifiers #1-2 corresponding to second port D2, and second identifiers #1-3 corresponding to second port D3, then the terminal can define beam D2 as a beam corresponding to a first port of the channel and / or reference signal. Beam D3 can be defined as another beam corresponding to the same first port of the channel and / or reference signal. That is, beams D2 and D3 can be defined as multiple beams corresponding to a first port of the channel and / or reference signal.

[0156] For example, if one second port of the second reference signal resource can determine one beam, then multiple second ports of the second reference signal resource can be used to determine multiple beams. For instance, if the first information includes a first identifier #1, second identifiers #1-3 corresponding to second port D3, and second identifiers #1-4 corresponding to second port D4, then the terminal can determine beam D3 as one beam corresponding to one first port of the channel and / or reference signal, and beam D4 as one beam corresponding to another first port of the channel and / or reference signal. That is, beams D3 and D4 can be determined as multiple beams corresponding to multiple first ports of the channel and / or reference signal. Each first port corresponds to one beam. It is understood that if the second reference signal resource has more second ports, multiple beams corresponding to each first port can also be determined; this disclosure does not provide examples of all such instances.

[0157] For example, multiple second ports of a second reference signal resource can determine a beam, and more second ports can determine multiple beams. However, it is understood that when multiple second ports correspond to the same beam, the first information may include only the second identifier corresponding to one of the second ports, and the terminal can use that second identifier to determine the same beam corresponding to the multiple second ports. For example, if second port D1 and second port D2 correspond to beam D5, and second port D3 and second port D4 correspond to beam D6, the first information may indicate the first identifier #1, the second identifier #1-1 corresponding to the second identifier of second port D1, or the second identifier #1-2 corresponding to second port D2, the second identifier #1-3 corresponding to second port D3, or the second identifier #1-4 corresponding to second port D4. For example, the first information may indicate the first identifier #1, the second identifier #1-1, and the second identifier #1-3. Another example is that the first information may indicate the first identifier #1, the second identifier #1-1, and the second identifier #1-4. Yet another example is that the first information may indicate the first identifier #1, the second identifier #1-2, and the second identifier #1-3. For example, the first information can indicate the first identifier #1, the second identifier #1-2, and the second identifier #1-4.

[0158] It is understood that in some cases, the first information may also simultaneously indicate the second identifier #1-1 and the second identifier 1-2, and correspondingly, it may also simultaneously indicate the second identifier #1-3 and the second identifier 1-4, without limitation in this disclosure.

[0159] In some embodiments, the first information may indicate multiple first identifiers, and each first identifier corresponds to a second reference signal resource, which is a multi-port reference signal resource. That is, the first information may indicate multiple first identifiers, enabling the terminal to determine multiple beams based on the second reference signal resources corresponding to the multiple first identifiers. Here, a multi-port reference signal resource can be understood as a reference signal resource transmitted on multiple ports, i.e., multiple ports transmit the same reference signal resource.

[0160] In some embodiments, a second reference signal resource corresponding to one first identifier is used to determine one or more beams, and multiple second reference signal resources corresponding to multiple first identifiers are used to determine multiple beams. Assume that first identifier #1 corresponds to second reference signal resource E, and first identifier #2 corresponds to second reference signal resource F. The second ports of second reference signal resource E include second port E1, second port E2, second port E3, and second port E4. The second ports of second reference signal resource F include second port F1, second port F2, second port F3, and second port F4.

[0161] For example, if a second reference signal resource corresponding to a first identifier can determine one beam, then multiple second reference signal resources corresponding to multiple first identifiers can determine multiple beams. For instance, if the first information includes a first identifier #1 and a second identifier #2, the beam E for transmitting and / or receiving the second reference signal resource E can be determined as a beam corresponding to the channel and / or reference signal. Similarly, the beam F for transmitting and / or receiving the second reference signal resource F can be determined as a beam corresponding to the channel and / or reference signal. In other words, beams E and F can be determined as multiple beams corresponding to the channel and / or reference signal.

[0162] For example, if a second reference signal resource corresponding to a first identifier can determine one beam, then multiple second reference signal resources corresponding to multiple first identifiers can determine multiple beams. For instance, if the first information includes a first identifier #1 and a second identifier #2, the beam E for transmitting and / or receiving the second reference signal resource E can be determined as one beam of a first port of the channel and / or reference signal. The beam F for transmitting and / or receiving the second reference signal resource F can be determined as another beam of the same first port of the channel and / or reference signal. That is, beams E and F are determined as multiple beams corresponding to a first port of the channel and / or reference signal.

[0163] For example, if a second reference signal resource corresponding to a first identifier can determine one beam, then multiple second reference signal resources corresponding to multiple first identifiers can determine multiple beams. For instance, if the first information includes a first identifier #1 and a second identifier #2, the beam E for transmitting and / or receiving the second reference signal resource E can be determined as a beam of a first port of the channel and / or reference signal. The beam F for transmitting and / or receiving the second reference signal resource F can be determined as a beam of another first port of the channel and / or reference signal. That is, beams E and F are determined as multiple beams corresponding to multiple first ports of the channel and / or reference signal, wherein each first port corresponds to one beam. It is understood that if the number of first identifiers is greater, multiple beams corresponding to each first port can also be determined, which will not be exemplified in this disclosure.

[0164] For example, if a second reference signal resource corresponding to a first identifier can determine one beam, then multiple second reference signal resources corresponding to multiple first identifiers can determine multiple beams. For instance, if first identifiers #1 and #2 in the first information, and second ports E1, E2, E3, and E4 correspond to the same beam E, and second ports F1, F2, F3, and F4 correspond to the same beam F, then beams E and F can be determined as multiple beams corresponding to the channel and / or reference signal.

[0165] For example, a second reference signal resource corresponding to a first identifier can determine multiple beams, and multiple second reference signal resources corresponding to first identifiers can determine even more beams. For example, if the first information includes first identifier #1 and first identifier #2. For example, beam E1 used to transmit and / or receive the second reference signal resource E at the second port E1 can be determined as a beam corresponding to the channel and / or reference signal. Beam E2 used to transmit and / or receive the second reference signal resource E at the second port E2 can be determined as another beam corresponding to the channel and / or reference signal. Beam F1 used to transmit and / or receive the second reference signal resource F at the second port F1 can be determined as a beam corresponding to the channel and / or reference signal. Beam F2 used to transmit and / or receive the second reference signal resource F at the second port F2 can be determined as another beam corresponding to the channel and / or reference signal. That is, beams E1, E2, F1, and F2 can be determined as multiple beams corresponding to the channel and / or reference signal.

[0166] For example, if a second reference signal resource corresponding to a first identifier can determine multiple beams, then second reference signal resources corresponding to multiple first identifiers can determine even more beams. For instance, if the first information includes first identifier #1 and first identifier #2, beams E1, E2, F1, and F2 can be determined as multiple beams corresponding to a first port of the channel and / or reference signal. As another example, beams E1, E2, F1, and F2 can be determined as multiple beams corresponding to multiple first ports of the channel and / or reference signal. Each first port corresponds to one beam. It is understood that if there are more second reference signal resources, or more second ports of the second reference signal resources, multiple beams corresponding to each first port can also be determined; this disclosure does not provide examples of all such cases.

[0167] In some embodiments, if the first information indicates multiple first identifiers, and each first identifier corresponds to a second reference signal resource, since the second reference signal resource is a multi-port reference signal resource, the first information may also indicate a second identifier for at least one first identifier, that is, indicate one or more second ports of the second reference signal resource corresponding to the first identifier. Assume that first identifier #1 corresponds to second reference signal resource E, and first identifier #2 corresponds to the second reference signal resource. The second ports of the second reference signal resource E include second port E1, second port E2, second port E3, and second port E4. The second ports of the second reference signal resource F include second port F1, second port F2, second port F3, and second port F4.

[0168] For example, if the first information indicates the first identifier #1, the second identifier #2, and the second identifier #1-1 corresponding to the second port E1, then for the second reference signal resource E corresponding to the first identifier #1, since the second identifier #1-1 corresponding to the second port E1 is indicated, a beam can be determined based on the second port E1. For the second reference signal resource F corresponding to the first identifier #2, since the second identifier is not indicated, multiple beams can be determined based on all ports of the second reference signal resource, i.e., the second port F1 and the second port F2. That is, beams E1, F1, and F2 can be determined as multiple beams corresponding to the channel and / or reference signal. The description of beams E1, F1, and F2 can be referred to the above embodiments, and will not be repeated here.

[0169] For example, if the first information indicates the first identifier #1, the second identifier #2, and the second identifier #2-2 corresponding to the second port F2, then for the second reference signal resource E corresponding to the first identifier #, since the second identifier is not indicated, multiple beams can be determined based on all ports of the second reference signal resource, i.e., the second port E1 and the second port E2. For the second reference signal resource F corresponding to the first identifier #2, since the second identifier #2-2 corresponding to the second port F2 is indicated, a beam can be determined based on the second port F2. For example, beams E1, E2, and F2 can be determined as multiple beams corresponding to a first port of the channel and / or reference signal.

[0170] For example, if the first information indicates a first identifier #1, a second identifier #2, a second identifier 1-2 corresponding to the second port E2, and a second identifier 2-1 corresponding to the second port F1, then for the second reference signal resource E corresponding to the first identifier #, since the second identifier 1-2 corresponding to the second port E2 is indicated, a beam can be determined based on the second port E2. For the second reference signal resource F corresponding to the first identifier #2, since the second identifier 2-1 corresponding to the second port F1 is indicated, a beam can be determined based on the second port F1. For example, beam E2 can be determined as a beam corresponding to one first port of the channel and / or reference signal. Beam F1 can be determined as a beam corresponding to another first port of the channel and / or reference signal. That is, beams E2 and F1 can be determined as multiple beams corresponding to multiple ports of the channel and / or reference signal. Each first port corresponds to one beam. It is understood that if there are more second reference signal resources, or more second ports of the second reference signal resources, multiple beams corresponding to each first port can also be determined, which will not be exemplified in this disclosure.

[0171] In some embodiments, the reference signal resource may be a synchronization signal block (SSB), a channel state information-reference signal resource (CSI-RS resource), etc., but is not limited to these. For example, the first reference signal resource may be an SSB, a CSI-RS resource, etc. As another example, the second reference signal resource may be an SSB, a CSI-RS resource, etc. As yet another example, if the second reference signal resource is an SSB, its second port may be an SSB port. As yet another example, if the second reference signal resource is a CSI-RS resource, its second port may be a CSI-RS port.

[0172] In some embodiments, the first identifier includes at least one of the following: an identifier of the reference signal resource; a cell index corresponding to the reference signal resource; and a physical cell identifier corresponding to the reference signal resource.

[0173] Optionally, the first identifier includes the identifier of the reference signal resource. The identifier of the reference signal resource can correspond to one reference signal resource, multiple reference signal resources, or a set of reference signal resources (i.e., all reference signal resources in a set), or multiple sets of reference resources (i.e., all reference signal resources in multiple sets). For example, the identifier of the reference signal resource can be RS#1, RS#2, RS#3, RS#4, etc., but is not limited to these. For instance, if the first identifier corresponds to a first reference signal resource, then the identifier of the reference signal resource is the identifier of the first reference signal resource; that is, the first identifier includes the identifier of the first reference signal resource. As another example, if the first identifier corresponds to a second reference signal resource, then the identifier of the reference signal resource is the identifier of the second reference signal resource; that is, the first identifier includes the identifier of the second reference signal resource.

[0174] Optionally, the first identifier includes the cell index corresponding to the reference signal resource. A cell may correspond to one or more reference signal resources, and a cell index may indirectly indicate the one or more reference signal resources corresponding to that cell. For example, the cell index may be cell#1, cell#2, cell#3, cell#4, etc., but is not limited to these. For instance, if the first identifier corresponds to a first reference signal resource, the first identifier may include the cell index corresponding to the first reference signal resource. As another example, if the first identifier corresponds to a second reference signal resource, the first identifier may include the cell index corresponding to the second reference signal resource.

[0175] Optionally, the first identifier includes the Physical Cell Identifier (PCI) corresponding to the reference signal resource. A cell may correspond to one or more reference signal resources, and a PCI may indirectly indicate one or more reference signal resources corresponding to that cell. For example, the PCI may be 0, 1, 2, 3, etc., but is not limited to these. For instance, if the first identifier corresponds to a first reference signal resource, the first identifier may include the PCI corresponding to the first reference signal resource. As another example, if the first identifier corresponds to a second reference signal resource, the first identifier may include the PCI corresponding to the second reference signal resource.

[0176] In some embodiments, the information field corresponding to the first information is a TCI state field. That is, the first information can be indicated at the position corresponding to the TCI state field. For example, a first identifier can be indicated at the position corresponding to the TCI state field. As another example, a first identifier and a second identifier can be indicated at the position corresponding to the TCI state field.

[0177] Optionally, the information field corresponding to the first information is the Quasi-Co Location (QCL) Type D field in the TCI state information element (IE). That is, the first information can be indicated at the location corresponding to the QCL Type D field in the TCI state IE. For example, the first identifier can be indicated at the location corresponding to the QCL Type D field in the TCI state IE. As another example, the first and second identifiers can be indicated at the location corresponding to the QCL Type D field in the TCI state IE.

[0178] In some embodiments, multiple first ports correspond to the same first identifier and / or second identifier in the first information.

[0179] Optionally, multiple first ports may correspond to the same first identifier in the first information.

[0180] For example, multiple first ports can correspond to the same first identifier. That is, one or more beams determined by a first identifier can be used for multiple first ports. For example, the first information includes a first identifier #1 and a first identifier #2. First ports #1 and #2 correspond to the first identifier #1 in the first information, and first ports #3 and #4 correspond to the first identifier #2 in the first information. Then, the terminal can use one or more beams determined based on the first identifier #1 to transmit and / or receive reference signals, signals on the channel, data, etc. on first ports #1 and #2. Correspondingly, the terminal can use one or more beams determined based on the first identifier #2 to transmit and / or receive reference signals, signals on the channel, data, etc. on first ports #3 and #4. The method by which the terminal determines one or more beams based on the first identifier #1 and one or more beams based on the second identifier #2 can be referred to the above embodiments, and will not be repeated here.

[0181] For example, multiple first ports can correspond to the same multiple first identifiers. That is, one or more beams determined by multiple first identifiers can be used for multiple first ports. For example, the first information includes first identifier #1 and first identifier #2. First port #1 corresponds to first identifier #1 and first identifier #2 in the first information, and first port #2 also corresponds to first identifier #1 and first identifier #2 in the first information. Then, the terminal can use one or more beams determined based on first identifier #1 and first identifier #2 to transmit and / or receive reference signals, signals on the channel, data, etc. on first port #1 and first port #2.

[0182] For example, some of the multiple first ports may correspond to the same first identifier, and some first ports may correspond to multiple first identifiers. For instance, the first information includes first identifier #1, first identifier #2, and first identifier #3. First port #1 and first port #2 correspond to first identifier #1 in the first information, first port #3 corresponds to first identifier #2 and first identifier #3, and first port #4 also corresponds to first identifier #2 and first identifier #3. Then, one or more beams determined by the terminal based on first identifier #1 can be used to transmit and / or receive reference signals, signals on the channel, data, etc., at first port #1 and first port #2. Similarly, one or more beams determined by the terminal based on first identifier #2 and first identifier #3 can be used to transmit and / or receive reference signals, signals on the channel, data, etc., at first port #3 and first port #4.

[0183] It is understandable that multiple first ports can correspond to a single first identifier, or multiple first identifiers. The number of first identifiers corresponding to multiple first ports in different groups can be the same or different.

[0184] Optionally, multiple first ports may correspond to the same second identifier in the first information.

[0185] For example, multiple first ports can correspond to the same second identifier. That is, one or more beams determined by a second identifier can be used for multiple first ports. For example, the first information includes a first identifier #1, a second identifier #1-1, and a second identifier #1-2. First ports #1 and #2 correspond to the second identifier #1-1 in the first information. First ports #3 and #4 correspond to the second identifier #1-2 in the first information. Then, one or more beams determined by the terminal based on the second identifier #1-1 can be used to transmit and / or receive reference signals, signals on the channel, data, etc., at first ports #1 and #2. Correspondingly, one or more beams determined by the terminal based on the second identifier #1-2 can be used to transmit and / or receive reference signals, signals on the channel, data, etc., at first ports #3 and #4. The manner in which the terminal determines one or more beams based on the second identifier #1-1 and one or more beams based on the second identifier #1-2 can be referred to the above embodiments, and will not be repeated here.

[0186] For example, multiple first ports can correspond to the same multiple second identifiers. That is, one or more beams determined by multiple second identifiers can be used for multiple first ports. For example, the first information includes a first identifier #1, a second identifier #1-1, and a second identifier #1-2. First port #1 can correspond to the second identifier #1-1 and the second identifier #1-2 in the first information. First port #2 can also correspond to the second identifier #1-1 and the second identifier #1-2 in the first information. Then, one or more beams determined by the terminal based on the second identifier #1-1 and the second identifier #1-2 can be used to transmit and / or receive reference signals, signals on the channel, data, etc., at first port #1 and first port #2.

[0187] For example, some of the multiple first ports may correspond to the same second identifier, and some first ports may correspond to multiple second identifiers. For instance, the first information includes a first identifier #1, a second identifier #1-1, a second identifier #1-2, and a second identifier #1-3. First ports #1 and #2 correspond to the second identifier #1-1 in the first information, first port #3 corresponds to the second identifier #1-2 and the second identifier #1-3, and first port #4 also corresponds to the second identifier #1-2 and the second identifier #1-3. Then, one or more beams determined by the terminal based on the second identifier #1-1 can be used to transmit and / or receive reference signals, signals on the channel, data, etc., at first ports #1 and #2. Similarly, one or more beams determined by the terminal based on the second identifier #1-2 and the second identifier #1-3 can be used to transmit and / or receive reference signals, signals on the channel, data, etc., at first ports #3 and #4.

[0188] It is understandable that multiple first ports can correspond to one second identifier, or multiple second identifiers. The number of second identifiers corresponding to multiple first ports in different groups can be the same or different.

[0189] It is understood that the above embodiments can be implemented in combination, and this disclosure does not limit them.

[0190] In some embodiments, the network device may send third information to the terminal, the third information being used to indicate that multiple first ports correspond to the same first identifier and / or second identifier in the first information.

[0191] In some embodiments, if the network device's TRP is a single TRP, and / or multiple first ports belong to the same Code Division Multiplexing (CDM) group, then the multiple first ports may correspond to the same first identifier and / or second identifier in the first information. For example, the network device may determine that its TRP is a single TRP, and thus send third information to the terminal to indicate that the multiple first ports correspond to the same first identifier and / or second identifier in the first information. As another example, the network device may determine that the multiple first ports belong to the same CDM group, and thus send third information to the terminal to indicate that the multiple first ports correspond to the same first identifier and / or second identifier in the first information. Here, "the network device's TRP is a single TRP" could mean that the network device has only one TRP, or that the network device has multiple TRPs but communicates with the terminal based only on one TRP, or that other TRPs are closed and only one TRP is open; this disclosure does not limit this.

[0192] In some embodiments, multiple first ports correspond to different first identifiers or second identifiers in the first information.

[0193] Optionally, multiple first ports correspond to different first identifiers in the first information. The different first identifiers in the first information can be used to determine one or more beams corresponding to different first ports. For example, the first information includes a first identifier #1 and a first identifier #2. First port #1 corresponds to the first identifier #1 in the first information, and first port #2 corresponds to the first identifier #2 in the first information. Then, the one or more beams determined by the terminal based on the first identifier #1 can be used to transmit and / or receive reference signals, signals on the channel, data, etc., at the first port #1. Correspondingly, the one or more beams determined by the terminal based on the first identifier #2 can be used at the first port #2. The method by which the terminal determines one or more beams based on the first identifier #1 and one or more beams based on the second identifier #2 can be referred to the above embodiments, and will not be repeated here.

[0194] Optionally, multiple first ports correspond to different second identifiers in the first information. That is, different second identifiers in the first information can be used to determine one or more beams corresponding to different first ports. For example, the first information includes a first identifier #1, a second identifier #1-1, and a second identifier #1-2. First port #1 corresponds to the second identifier #1-1 in the first information. First port #2 corresponds to the second identifier #1-2 in the first information. Then, one or more beams determined by the terminal based on the second identifier #1-1 can be used to transmit and / or receive reference signals, signals on the channel, data, etc., at first port #1. Correspondingly, one or more beams determined by the terminal based on the second identifier #1-2 can be used to transmit and / or receive reference signals, signals on the channel, data, etc., at first port #2. The method by which the terminal determines one or more beams based on the second identifier #1-1 and one or more beams based on the second identifier #1-2 can refer to the above embodiments, and will not be repeated here.

[0195] It is understood that the above embodiments can be implemented in combination, and this disclosure does not limit them.

[0196] In some embodiments, the network device may send third information to the terminal, the third information being used to indicate that multiple first ports correspond to different first identifiers or second identifiers in the first information.

[0197] In some embodiments, if the network device has multiple TRPs and / or multiple first ports belong to different CDM groups, then the multiple first ports may correspond to different first identifiers and / or second identifiers in the first information. For example, the network device may determine that its TRP is multiple TRPs, and thereby indicate to the terminal that the multiple first ports correspond to different first identifiers and / or second identifiers in the first information by sending third information. As another example, the network device may determine that the multiple first ports belong to different CDM groups, and thereby indicate to the terminal that the multiple first ports correspond to different first identifiers and / or second identifiers in the first information by sending third information.

[0198] In some embodiments, the multiple beams determined by the terminal based on the first information can be used for the transmission of channels and / or reference signals in different time domains, and the transmission mode of the channels and / or reference signals is time division multiplexing (TDM). This allows for improved transmission performance based on the determined multiple beams while efficiently utilizing bandwidth and enhancing anti-interference capabilities.

[0199] In some embodiments, the multiple beams determined by the terminal based on the first information can be used for the transmission of channels and / or reference signals in different frequency domains, and the transmission mode of the channels and / or reference signals is frequency division multiplexing (FDM). This allows for improved transmission performance based on the determined multiple beams while efficiently utilizing bandwidth and reducing mutual interference across frequencies.

[0200] In some embodiments, the multiple beams determined by the terminal based on the first information can be used for the transmission of channels and / or reference signals in the same time and frequency domains. The transmission mode of the channels and / or reference signals is multiple first ports corresponding to different code division multiplexing groups (CDM groups) or single frequency network (SFN) transmission modes. This allows for improved transmission performance while simultaneously increasing coverage and signal quality based on the determined multiple beams.

[0201] In some embodiments, the third information includes the transmission mode, such as indicating whether the transmission mode of the channel / reference signal is TDM, FDM, or whether the DMRS port belongs to a different CDM group or SFN.

[0202] In step S2102, terminal 101 sends second information to network device 102.

[0203] In some embodiments, network device 102 receives second information sent by terminal 101.

[0204] In some embodiments, the second information is used to indicate one or more beam combinations, wherein each beam combination includes multiple beams that the terminal can transmit or receive simultaneously. For example, after measuring the reference signal on the reference signal resource for beam measurement transmitted by the base station, the terminal can combine multiple beams that the terminal can transmit or receive simultaneously from multiple beams into a beam combination, and there can be one or more beam combinations, which are reported to the network device.

[0205] In some embodiments, the second information includes at least one of the following information corresponding to each beam combination: a third identifier, which is an identifier of the reference signal resource; a fourth identifier, which is a port identifier of the reference signal resource; Layer 1 reference signal received power (L1-RSRP); and Layer 1 signal to interference plus noise ratio (L1-SINR).

[0206] Optionally, the second information includes a third identifier corresponding to each beam combination, whereby the third identifier is an identifier for the reference signal resource.

[0207] Optionally, the second information includes a third identifier corresponding to each beam combination, and the third identifier corresponds to a second reference signal resource. That is, the third identifier can be an identifier of the second reference signal resource, and the second reference signal resource is a multi-port reference signal resource. For example, the multiple beams corresponding to the multiple second ports of the second reference signal resource are the multiple beams included in the beam combination.

[0208] Optionally, the second information includes multiple third identifiers corresponding to each beam combination. Each of the multiple third identifiers can correspond to a second reference signal resource. Multiple second ports of the second reference signal resource corresponding to each third identifier can correspond to one or more beams. The second reference signal resources corresponding to the multiple third identifiers correspond to multiple beams, which are the multiple beams included in the beam combination.

[0209] Optionally, the second information includes a fourth identifier corresponding to each beam combination, where the fourth identifier is one or more fourth identifiers of the reference signal resources corresponding to the third identifier. For example, the reference signal resources corresponding to the third identifier include N ports, but the beam combination only indicates the fourth identifiers corresponding to M ports. Here, M and N are positive integers, and N is greater than M.

[0210] Optionally, the second information includes a third identifier corresponding to each beam combination, and a fourth identifier corresponding to the reference signal resource corresponding to the third identifier, wherein the fourth identifier is a port identifier of the reference signal resource. For example, a beam combination may include a third identifier and one or more fourth identifiers corresponding to that third identifier. For example, the third identifier corresponds to a second reference signal resource, which is a multi-port reference signal resource, and one or more fourth identifiers correspond to one or more second ports of the second reference signal resource. The multiple beams corresponding to one or more second ports constitute the multiple beams included in the beam combination.

[0211] Optionally, the second information includes multiple third identifiers corresponding to each beam combination, and a fourth identifier corresponding to at least one third identifier and a reference signal resource, where the fourth identifier is a port identifier of the reference signal resource. For example, for a third identifier, if the second information includes one or more fourth identifiers corresponding to that third identifier, then the beams corresponding to the one or more fourth identifiers are considered as the beams corresponding to that third identifier. If the second information does not include one or more fourth identifiers corresponding to that third identifier, and the third identifier corresponds to a second reference signal resource, then the multiple beams corresponding to the multiple second ports of the second reference signal resource are considered as the beams corresponding to that third identifier. The multiple beams corresponding to the multiple third identifiers are the multiple beams included in the beam combination.

[0212] Optionally, the second information includes the L1-RSRP corresponding to each beam in each beam combination. For example, each beam combination includes multiple beams, and each beam can correspond to one L1-RSRP.

[0213] Optionally, the second information includes the L1-SINR corresponding to each beam in each beam combination. For example, each beam combination includes multiple beams, and each beam may correspond to one L1-SINR.

[0214] In some embodiments, the name of the second information is not limited, and it may be, for example, "beam report", "reported information", etc.

[0246] Figure 5 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 5, the embodiments of the present disclosure relate to a communication method, which includes:

[0247] In step S5101, network device 102 sends first information to terminal 101.

[0248] In some embodiments, the above methods may include the methods of the embodiments related to the communication system 100, terminal 101, and network device 102, which will not be described again here.

[0249] This disclosure provides a communication method as follows:

[0250] In some embodiments, the terminal receives first indication information, which is used to determine the channel and / or the multiple beams corresponding to at least one DMRS port.

[0251] In some embodiments, the beam can be referred to as any one of beam, QCL Type D, spatial Rx parameter, spatial Tx parameter, spatial setting, spatial relationinfor, spatial reception parameter, spatial transmission parameter, or TCI state.

[0252] In some embodiments, the first indication information indicates multiple reference signal resource identifiers, and each reference signal resource identifier corresponds to a reference signal resource for one port. For example, the reference signal resource IDs are: RS#1, RS#2, RS#3, RS#4, etc.

[0253] Optionally, the above embodiments can correspond to the cases of S-TRP and M-TRP.

[0254] In some embodiments, the corresponding indication information field may be the position indication reference signal resource ID corresponding to the QCL Type D field in the TCI state IE.

[0255] In some embodiments, the reference signal resource may be CSI-RS or SSB.

[0256] In some embodiments, the cell index or PCI corresponding to the reference signal resource may further be indicated.

[0257] In some embodiments, each reference signal resource is used to determine a beam.

[0258] In some embodiments, the first indication information indicates a reference signal resource identifier, the reference signal resource corresponding to which is a multi-port reference signal resource. For example, it indicates a reference signal resource ID: RS#1. However, the port corresponding to RS is N ports. Further, the first indication information may indicate a port (group) identifier.

[0259] Optionally, the above embodiments can correspond to the S-TRP case.
