[0053] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0054] It should be noted that the terms "first," "second," and the like in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the numbers used in this manner are interchangeable where appropriate so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure as detailed in the appended claims.

[0055] In one embodiment, Figure 1 As shown, a beam association method is provided. This embodiment uses the method applied to a communication device as an example for illustration. It is understandable that the communication device can be a TRP (Transmit / Receive Point) or other communication devices, such as a personal computer, a laptop, a smartphone, a tablet computer, etc. In this embodiment, the method includes the following steps:

[0056] Step S110, obtain the number of SSB beams configurable by the TRP, the number of antenna panels placed in the user equipment, and the number of panel beams configurable by the antenna panels placed in the user equipment.

[0057] The number of panel beams specifically refers to the number of configurable beams of each antenna panel placed in the user equipment.

[0058] Among them, the user equipment (UE) is a device that communicates with the TRP, which can be but is not limited to various personal computers, laptops, smart phones, tablets and portable wearable devices.

[0059] The antenna units can be organized into different antenna panels, placed at different locations of the UE and facing different directions, to provide higher transmission rates and stronger robustness.

[0060] Among them, the number of SSB beams, the number of antenna panels and the number of panel beams are at least one.

[0061] In a specific implementation, for the TRP and UE to be communicated, the communication device can obtain the number of SSB beams that can be configured for the TRP as the number of SSB beams; obtain the number of antenna panels (UE panels) placed in the UE as the number of antenna panels; obtain the number of configurable beams (UE panel beam) of each antenna panel placed in the user equipment as the number of panel beams.

[0062] Step S120: Configure PO candidate positions according to the number of SSB beams, the number of antenna panels, and the number of panel beams.

[0063] In the specific implementation, the communication equipment can plan the location distribution and number of PO (PRACH (Physical Random Access Channel) Occasion) according to the number of SSB beams, the number of antenna panels and the number of panel beams, so that the planned PO positions can be used as PO candidate positions, and the PO candidate positions can be configured based on the number of SSB beams, the number of antenna panels and the number of panel beams.

[0064] In step S130, the SSB beam index that matches the number of SSB beams, the panel index that matches the number of antenna panels, and the panel beam index that matches the number of panel beams are associated with the PO candidate positions to obtain a mapping relationship between the associated beam pair index and the PO candidate position.

[0065] Among them, the SSB beam index is used to characterize the SSB beam; the panel index is used to characterize the antenna panel placed in the UE; and the panel beam index is used to characterize the configurable beam of the antenna panel placed in the UE.

[0066] The SSB beam index matches the number of SSB beams, that is, the number of SSB beam indices is equal to the number of SSB beams. For example, if the number of SSB beams that can be configured in the TRP is 2, then there can be 2 SSB beam indices, such as SSB 0 and SSB 1.

[0067] The panel index matches the number of antenna panels, i.e., the number of panel indexes is equal to the number of antenna panels placed in the user equipment. For example, if there are two antenna panels, there can be two panel indexes, such as panel 0 and panel 1.

[0068] The panel beam index that matches the number of panel beams means that for each antenna panel placed in the user equipment, the number of corresponding panel beam indices is equal to the number of configurable panel beams. For example, if the number of configurable panel beams for each antenna panel placed in the user equipment is four, then each antenna panel can correspond to four panel beam indices. For example, if the antenna panel is panel 1, the corresponding four panel beam indices can be Panel 1beam 0, Panel 1beam 1, Panel 1beam 2, and Panel 1beam 3, respectively.

[0069] It is understandable that indexes of other data types may also be used as SSB beam indexes, panel indexes, and panel beam indexes, which are not specifically limited here.

[0070] In a specific implementation, the communication device can respectively associate the SSB beam index that matches the number of SSB beams, the panel index that matches the number of antenna panels, and the panel beam index that matches the number of panel beams with the PO candidate positions, so that each PO candidate position is associated with a corresponding SSB beam index, panel index, and panel beam index, and the SSB beam index, panel index, and panel beam index associated with the PO candidate position can be used as the associated beam pair index corresponding to the PO candidate position, so that the communication device can obtain the mapping relationship between the associated beam pair index and the PO candidate position.

[0071] In this way, after obtaining the above mapping relationship, TRP can determine the associated beam pair index that matches the PO position according to the PO position corresponding to the random access preamble code preamble sent by the received UE in the above mapping relationship, so that TRP can determine not only the target SSB beam used for downlink transmission when communicating with the UE, but also the target panel beam from the target antenna panel for uplink reception based on the SSB beam index, panel index and panel beam index contained in the associated beam pair index that matches the PO position. The target SSB beam is the optimal SSB beam for downlink transmission, and the target panel beam is the optimal panel beam for uplink reception (optimal UE panel beam).

[0072] In the above beam association method, the number of SSB beams configurable by TRP, the number of antenna panels placed in the user equipment, and the number of panel beams configurable by the antenna panels placed in the user equipment are obtained; the PO candidate positions are configured according to the number of SSB beams, the number of antenna panels, and the number of panel beams; the SSB beam index matching the number of SSB beams, the panel index matching the number of antenna panels, and the panel beam index matching the number of panel beams are respectively associated with the PO candidate positions to obtain a mapping relationship between the associated beam pair index and the PO candidate position; the associated beam pair index includes a paired SSB beam index and a panel beam index; the mapping relationship is used to determine the target SSB beam for downlink transmission and the target panel beam for uplink reception.

[0073] In this way, TRP can determine the associated beam pair index that matches the PO position corresponding to the random access preamble code sent by the user equipment in the above mapping relationship, so as to determine not only the target SSB beam for downlink transmission but also the target panel beam received in the uplink from the target panel according to the SSB beam index, panel index and panel beam index contained in the matching associated beam pair index, thereby solving the problem in the related art that the source of the optimal UE panel beam received cannot be determined, and realizing the association and correspondence between TRP SSB and UE panel beam in the random access stage, thereby reducing signaling interaction and transmitting data information in a timely and effective manner.

[0074] In one embodiment, Figure 2 As shown, step S120, configuring PO candidate positions according to the number of SSB beams, the number of antenna panels, and the number of panel beams, includes the following steps:

[0075] Step S210: Configure PO candidate positions in the time domain according to the number of SSB beams and the number of antenna panels to obtain PO time domain candidate positions.

[0076] In a specific implementation, when the communication device configures the PO candidate positions according to the number of SSB beams, the number of antenna panels and the number of panel beams, the communication device can plan the number of PO positions in the time domain according to the number of SSB beams and the number of antenna panels, so that the PO positions planned in the time domain can be used as PO time domain candidate positions, thereby realizing the configuration of PO candidate positions in the time domain based on the number of SSB beams and the number of antenna panels.

[0077] For example, A represents the number of SSB beams that can be configured by TRP, and B represents the number of UE panels, that is, the number of antenna panels placed in the user equipment. Then, A*B PO candidate positions can be configured in the time domain, that is, A*B PO time domain candidate positions can be configured.

[0078] Step S220: According to the number of panel beams, PO candidate positions are configured in the frequency domain to obtain PO frequency domain candidate positions.

[0079] In a specific implementation, while the communication device is configuring the PO candidate positions according to the number of SSB beams, the number of antenna panels, and the number of panel beams, the communication device can also plan the number of PO positions in the frequency domain according to the number of panel beams, so that the PO positions planned in the frequency domain can be used as PO frequency domain candidate positions, thereby realizing the configuration of PO candidate positions in the frequency domain based on the number of panel beams.

[0080] For example, C represents the number of configurable beams of the UE panel, that is, C represents the number of configurable panel beams of each antenna panel placed in the user equipment; then, C PO candidate positions can be configured in the frequency domain, that is, C PO frequency domain candidate positions are configured.

[0081] To facilitate understanding by those skilled in the art, in the case of A=2; B=2; C=4, Figure 3 A schematic diagram of configured PO candidate locations is provided.

[0082] It should be noted that the numbers of A, B and C can also be other values ​​and are not specifically limited here.

[0083] The technical solution of this embodiment configures the PO candidate position in the time domain according to the number of SSB beams and the number of antenna panels to obtain the PO time domain candidate position; configures the PO candidate position in the frequency domain according to the number of panel beams to obtain the PO frequency domain candidate position; in this way, the PO time domain candidate position is configured by the number of SSB beams and the number of antenna panels; the PO frequency domain candidate position is configured by the number of panel beams, which lays the foundation for associating the SSB beam index, panel index and panel beam index with the PO time domain candidate position, and the PO frequency domain candidate position, so that the association between the PO position and the SSB beam and the UEpanel beam can be further realized.

[0084] In one embodiment, the PO candidate position includes a PO time domain candidate position and a PO frequency domain candidate position; the SSB beam index that matches the number of SSB beams, the panel index that matches the number of antenna panels, and the panel beam index that matches the number of panel beams are respectively associated with the PO candidate position to obtain a mapping relationship between the associated beam pair index and the PO candidate position, including: associating the SSB beam index and the panel index with the PO time domain candidate position to obtain a time domain association relationship; associating the panel beam index with the PO frequency domain candidate position to obtain a frequency domain association relationship; according to the time domain association relationship and the frequency domain association relationship, a mapping relationship between the associated beam pair index and the PO candidate position is obtained.

[0085] In a specific implementation, the communication device associates the SSB beam index that matches the number of SSB beams, the panel index that matches the number of antenna panels, and the panel beam index that matches the number of panel beams with the PO candidate positions to obtain a mapping relationship between the associated beam pair index and the PO candidate position. In the process, the communication device can associate the SSB beam index and the panel index with the PO time domain candidate position to obtain a time domain association relationship, and associate the panel beam index with the PO frequency domain candidate position to obtain a frequency domain association relationship. Thus, the communication device can obtain a mapping relationship between the associated beam pair index and the PO candidate position based on the time domain association relationship and the frequency domain association relationship.

[0086] The technical solution of this embodiment is to obtain a time domain association relationship by associating the SSB beam index and the panel index with the PO time domain candidate position; to obtain a frequency domain association relationship by associating the panel beam index with the PO frequency domain candidate position; and to obtain a mapping relationship between the associated beam pair index and the PO candidate position based on the time domain association relationship and the frequency domain association relationship; in this way, the PO time domain candidate position is configured by the number of SSB beams and the number of antenna panels; and the PO frequency domain candidate position is configured by the number of panel beams, and the SSB beam index and the panel index are associated with the PO time domain candidate position, and the panel beam index is associated with the PO frequency domain candidate position, so that the association between the PO position and the SSB beam and the UE panel beam in the frequency domain and time domain can be achieved.

[0087] In one embodiment, the SSB beam index and the panel index are associated with the PO time domain candidate position to obtain a time domain association relationship, including: in each round of association period of associating the SSB beam index with the PO time domain candidate position, the SSB beam index is associated with the PO time domain candidate position in the order of increasing SSB beam index and increasing PO time domain candidate position index; when the number of completed association rounds reaches the number of antenna panels, the panel index is associated with the PO time domain candidate position to obtain a time domain association relationship.

[0088] In a specific implementation, when the communication device associates the SSB beam index and the panel index with the PO time domain candidate position to obtain a time domain association relationship, within each association period of associating the SSB beam index with the PO time domain candidate position, the communication device can associate the SSB beam index with the PO time domain candidate position in the order of increasing SSB beam index and increasing PO time domain candidate position index. When the number of completed association rounds reaches the number of antenna panels, the panel index is associated with the PO time domain candidate position to obtain a time domain association relationship.

[0089] For example, continuing with the previous example, within the association period of each round of SSB beam index association to the PO time domain candidate position, in the order of increasing SSB beam index and the order of increasing PO time domain candidate position index; the association of B rounds of SSB beam index to PO time domain candidate position needs to be completed.

[0090] Among them, when the number of completed association rounds reaches the number of antenna panels, the panel index is associated with the PO time domain candidate position to obtain the time domain association relationship. In the process, each panel index is associated with one association cycle, and the panel index is associated with the PO time domain candidate position in the order of increasing panel index and the order of increasing PO time domain candidate position index to obtain the time domain association relationship.

[0091] The technical solution of the embodiment is that, in the association period of each round of SSB beam index association to PO time domain candidate position, the SSB beam index is associated to the PO time domain candidate position in the order of increasing SSB beam index and in the order of increasing PO time domain candidate position index; in the case that the number of rounds of association reaches the number of antenna panels, the panel index is associated to the PO time domain candidate position to obtain the time domain association relationship. In this way, the panel index can be associated to the PO time domain candidate position according to the preset principle to obtain the time domain association relationship.

[0092] In one embodiment, the panel beam index is associated to the PO frequency domain candidate position to obtain the frequency domain association relationship, including: the panel beam index is associated to the PO frequency domain candidate position in the order of increasing panel beam index and in the order of increasing PO frequency domain candidate position index to obtain the frequency domain association relationship.

[0093] In the specific implementation, in the process of associating the panel beam index to the PO frequency domain candidate position to obtain the frequency domain association relationship, the communication device can associate the panel beam index to the PO frequency domain candidate position in the order of increasing panel beam index and in the order of increasing PO frequency domain candidate position index to obtain the frequency domain association relationship.

[0094] For the convenience of those skilled in the art, in the above example, in the case of A=2; B=2; C=4, Figure 4 A PO candidate position diagram associated according to the above principle is provided. As shown in Figure 4 It can be realized that the SSB beam index, the panel index and the panel beam index are associated to the PO candidate position in the case of multiple panels.

[0095] The technical solution of the embodiment is that, in the association period of each round of SSB beam index association to PO time domain candidate position, the SSB beam index is associated to the PO time domain candidate position in the order of increasing SSB beam index and in the order of increasing PO time domain candidate position index; in the case that the number of rounds of association reaches the number of antenna panels, the panel index is associated to the PO time domain candidate position to obtain the time domain association relationship. In this way, the panel index can be associated to the PO time domain candidate position according to the preset principle to obtain the time domain association relationship.

[0096] In one embodiment, another beam association method is provided, which can be applied to the application environment as shown in Figure 5 As shown in Figure 5 The TRP is used to send a downlink SSB beam, and the UE is used to send an uplink panel beam (a beam originating from an antenna panel in a user equipment, which can be named as a panel beam). Through the method, the TRP can not only determine the target panel beam as the optimal downlink SSB beam, but also determine the source of the optimal uplink UE panel beam. Taking the case that the method is applied to the TRP as an example, as shown in Figure 6 As shown, the following steps are included:

[0097] Step S610: Receive a random access preamble sent by a user equipment, and determine a PO position corresponding to the random access preamble.

[0098] The PO position includes the PO time domain position and the PO frequency domain position.

[0099] In the specific implementation, the SSB beam has multiple transmission opportunities within the time domain period and has corresponding index numbers, which can correspond to different SSB beams respectively. Through beam scanning, TRP can send different SSB beams at multiple times. When the scanning signal of the SSB beam covers the UE, the UE can send a random access preamble to the TRP, and the TRP can receive the random access preamble sent by the UE. The TRP can determine the PO position corresponding to the random access preamble.

[0100] Step S620: Determine a target associated beam pair index that matches the PO position in the mapping relationship between the associated beam pair index and the PO candidate position.

[0101] Among them, the SSB beam index, panel index and panel beam index in the target associated beam pair index are used as the target SSB beam index, target panel index and target panel beam index respectively.

[0102] In the specific implementation, TRP can obtain the mapping relationship between the associated beam pair index and the PO candidate position, and in the mapping relationship between the associated beam pair index and the PO candidate position, determine the associated beam pair index that matches the PO position as the target associated beam pair index.

[0103] Step S630, using the SSB beam corresponding to the target SSB beam index as the target SSB beam for downlink transmission, and using the panel beam corresponding to the target panel index and the target panel beam index as the target panel beam for uplink reception.

[0104] In the specific implementation, TRP can use the SSB beam corresponding to the target SSB beam index as the downlink best SSB beam and as the target SSB beam for downlink transmission. In addition, TRP can also use the panel beam corresponding to the target panel index and the target panel beam index as the target panel beam derived from the target antenna panel (the antenna panel corresponding to the target panel index), and use the target panel beam derived from the target antenna panel as the uplink best UE panel beam, as the target panel beam for uplink reception, to achieve the association and correspondence between the TRP SSB and the UE panel beam in the random access phase.

[0105] In the above-mentioned beam association method, applied to TRP, by receiving the random access preamble sent by the user equipment and determining the PO position corresponding to the random access preamble; in the mapping relationship between the association beam pair index and the PO candidate position, the target association beam pair index matching the PO position is determined; the target association beam pair index includes the target SSB beam index, the target panel index and the target panel beam index; the SSB beam corresponding to the target SSB beam index is used as the target SSB beam for downlink transmission, and the panel beam corresponding to the target panel index and the target panel beam index is used as the target panel beam for uplink reception. In this way, not only the target SSB beam for downlink transmission can be determined, but also the target panel beam from the target antenna panel for uplink reception can be determined, which solves the problem in the related art that the source of the optimal UE panel beam received cannot be determined, and realizes the association correspondence between the TRP SSB and the UE panel beam in the random access phase, thereby reducing signaling interaction and transmitting data information in a timely and effective manner.

[0106] It should be noted that the above-mentioned beam association method can be applied to 5G millimeter wave FR2-only (5G millimeter wave independent networking mode) networking scenarios, where the UE activates the Multi-Panel function and supports Multi-TRP multi-station transmission, etc., to determine the association between TRP SSB and UE panel beam in the random access phase.

[0107] In one embodiment, Figure 7 As shown, a flow chart of another beam association method is provided. In this embodiment, the method includes the following steps:

[0108] In step S710, the communication device obtains the number of SSB beams configurable by the TRP, the number of antenna panels placed in the user equipment, and the number of panel beams configurable by the antenna panels placed in the user equipment.
