[0002] With the development of communication technology, wireless communication can be achieved based on non-terrestrial networks (NTNs).

[0047] Figure 1This diagram illustrates a block diagram of a wireless communication system applicable to embodiments of this application.

[0048] For ease of understanding, the following describes some aspects of the embodiments of this application:

[0049] I. NTN System.

[0050] In the 5G era and the subsequent 6G era, the disadvantages of terrestrial networks in terms of large-scale dense deployment and energy consumption can be made up for by NTN systems. The advantages of satellite communication in terms of coverage, reliability and flexibility can make up for the shortcomings of terrestrial mobile communication.

[0051] like Figure 2 and Figure 3 The diagram shows two typical micro communication networks. Figure 2 As shown, Figure 2 This is a network diagram illustrating a typical non-terrestrial network scenario based on a transparent payload, such as... Figure 3 As shown, Figure 3 This is a network diagram illustrating a typical scenario of a non-terrestrial network based on a regenerative payload.

[0052] Transparent payloads refer to payloads where the satellite does not alter the received signal, but only amplifies and retransmits it; regenerative payloads, on the other hand, involve satellites possessing some or all of the functions of a base station. Figure 2 and Figure 3 As shown, the satellite covers a certain area through several beams, and the coverage area is elliptical. Optionally, the satellite can also be referred to as a high-altitude platform.

[0053] Optionally, for non-geostationary orbit (Non-GEO) satellites, because the satellite is in motion relative to the Earth, its relative position changes over time, causing changes in its coverage area. To address this, two different modes are designed: earth-fixed cells and earth-moving cells. For earth-fixed cells, the coverage area on the ground remains unchanged as the satellite moves, by adjusting the antenna's pointing direction. For earth-moving cells, the coverage area on the ground moves with the satellite's movement.

[0054] In terrestrial networks (TN), multiple beams also exist for coverage, but only one beam can be used for transmission within the same cell at any given time, and all beams use the same frequency band. However, in NTN systems, all beams of a satellite can operate simultaneously, and different beams can operate on different frequency resources.

[0055] The beam measurement method in the NTN scenario provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0056] Please see Figure 4 , Figure 4 This is a flowchart of a beam measurement method in an NTN scenario provided by an embodiment of this application, as shown below. Figure 4 As shown, it includes the following steps:

[0057] Step 401: The terminal obtains the first signaling sent by the network-side device;

[0058] In this embodiment, the network-side device can directly or indirectly send the first signaling to the terminal. In some embodiments, the network-side device is a satellite with base station functionality, in which case the network-side device can directly send the first signaling to the terminal via the NTN network. In some embodiments, the network-side device is a base station, which can send the first signaling to the satellite, and then the satellite forwards the first signaling to the terminal via the NTN network.

[0059] It should be noted that the transmission method of the first signaling can be configured according to actual needs. For example, in some embodiments, the first signaling is carried by at least one of the following: Radio Resource Control (RRC), Media Access Control Element (MAC CE), and Downlink Control Information (DCI). In the embodiments of this application, when the first signaling is carried by at least two of the above carriers, it can be understood that the first signaling may include multiple sub-signalings, with different sub-signalings carrying different information content, and thus can be carried by at least two of RRC, MAC CE, and DCI. In some embodiments, when the first signaling is carried by at least two of the above carriers, it can also be understood that the first signaling is repeatedly transmitted through RRC, MAC CE, and DCI.

[0060] Step 402: The terminal determines the first configuration information corresponding to each beam in the first measurement beam set according to the first signaling.

[0061] Step 403: The terminal performs beam measurement according to the first configuration information;

[0062] The first configuration information includes at least one of the following: frequency band configuration information and antenna polarization direction.

[0063] In this embodiment, the aforementioned first configuration information can be agreed upon by the protocol or configured by the network-side device, and no further limitations are made here. Optionally, after the terminal receives the first signaling, it can first determine the first configuration information corresponding to each beam in the first measurement beam set. Based on the first configuration information, the terminal performs beam measurement. Since the terminal determines the first configuration information corresponding to each beam according to the first signaling, it can achieve the measurement of adjacent beams in the NTN scenario, thereby improving the beam measurement range and enabling switching to the optimal beam for transmission. Therefore, this embodiment improves the transmission performance in the NTN scenario, thereby improving the reliability of transmission.

[0064] This application embodiment obtains a first signaling sent by a network-side device through a terminal; the terminal determines first configuration information corresponding to each beam in a first measurement beam set based on the first signaling; and performs beam measurement according to the first configuration information; wherein the first configuration information includes at least one of the following: frequency band configuration information and antenna polarization direction. In this way, adjacent beam measurement is achieved in NTN scenarios, improving the beam measurement range and thus improving transmission performance in NTN scenarios, thereby enhancing transmission reliability.

[0065] Optionally, in some embodiments, the frequency band configuration information of the beam includes at least one of the following: the bandwidth portion (BWP) configuration information of the beam and the frequency domain resource information of the beam.

[0066] The BWP configuration information may include at least one of the following: frequency domain location, bandwidth, subcarrier space (SCS), cyclic prefix (CP) type, and BWP index (ID). The frequency domain resource information of the aforementioned beam may include frequency band and component carrier (CC), etc.

[0067] The aforementioned antenna polarization directions can include linear polarization, left-hand circular polarization, right-hand circular polarization, and a combination of left-hand and right-hand circular polarization.

[0068] Optionally, in some embodiments, the BWP configuration information is determined based on preset rules, which include at least one of the following:

[0069] At least some configuration parameters are the same in the first BWP configuration information of a terminal;

[0070] At least some of the configuration parameters are the same in the second BWP configuration information of a beam;

[0071] The second BWP configuration information for one beam is dedicated BWP configuration information;

[0072] At least some configuration parameters are the same in the third BWP configuration information of a community;

[0073] The third BWP configuration information for a community is dedicated BWP configuration information.

[0074] In this embodiment of the application, the fact that some configuration parameters are the same in the first BWP configuration information of a terminal can be understood as: in multiple first BWP configuration information of a terminal, some configuration parameters of any two first BWP configuration information are the same. Here, multiple first BWP configuration information can be understood as BWP configuration information corresponding to different time domains, or as BWP configuration information corresponding to different BWPs.

[0075] The idea that some configuration parameters are the same in the second BWP configuration information for a single beam can be understood as follows: among multiple second BWP configuration information for a single beam, any two second BWP configuration information sets share some configuration parameters. These multiple second BWP configuration information sets can be understood as BWP configuration information corresponding to different time domains, or as BWP configuration information corresponding to different terminals or BWPs.

[0076] The statement that some configuration parameters are the same in the third BWP configuration information of a cell can be understood as: among multiple third BWP configuration information of a cell, any two third BWP configuration information have some configuration parameters that are the same. These multiple third BWP configuration information can be understood as BWP configuration information corresponding to different time domains, or as BWP configuration information corresponding to different beams, terminals, or BWPs.

[0077] Optionally, for a beam, there exists a dedicated BWP.

[0078] Optionally, a dedicated BWP exists for the entire community.

[0079] The aforementioned configuration parameters may include at least one of the following: bandwidth, SCS, and BWP ID. It should be understood that, in this embodiment, the aforementioned BWP configuration information may be dynamically configured BWP configuration information.

[0080] Optionally, in some embodiments, the first signaling carries target information, which includes at least one of the following:

[0081] Beam measurement indication;

[0082] The second configuration information is used to indicate the second measurement beam set, which includes the first measurement beam set;

[0083] The first configuration information;

[0084] Beam measurement activation time information;

[0085] Measurement duration.

[0086] In this embodiment, a preset beam set for performing beam measurement and first configuration information corresponding to each beam can be pre-defined by a protocol. The terminal is triggered to perform beam measurement via this first signaling. At this time, the terminal can perform beam measurement on the first measurement beam set of the preset beam set. Of course, in other embodiments, a subset of beams can be selected from the preset beam set as the first measurement beam set to be measured and then performed beam measurement.

[0087] Optionally, in some embodiments, a second set of measurement beams for beam measurement can be indicated by the second configuration information or the first configuration information described above. In this case, the terminal can perform beam measurement using the second set of measurement beams as the first set of measurement beams to be measured, or it can select a portion of the beams in the second set of measurement beams as the first set of measurement beams to be measured. In other words, in the embodiments of this application, when the first signaling carries a first object and indicates the second measurement beam through the first object, the terminal determines, based on the first signaling, that the first configuration information corresponding to each beam in the first set of measurement beams includes any one of the following:

[0088] The terminal determines the first configuration information corresponding to each beam in the second measurement beam set;

[0089] The terminal determines a portion of the beams in the second measurement beam set as the first measurement beam set, and determines the first configuration information corresponding to each beam in the first measurement beam set;

[0090] The first object includes at least one of the first configuration information and the second configuration information.

[0091] In this embodiment of the application, when selecting a portion of beams as the first measurement beam set based on the second measurement beam set, the first measurement beam set can be determined based on at least one of the following:

[0092] The location information of the terminal;

[0093] The terminal's moving speed and direction of movement;

[0094] The polarization direction supported by the receiving antenna of the terminal;

[0095] The satellite's ephemeris information, wherein the satellite is the network-side device or the satellite is used to forward the first signaling sent by the network-side device.

[0096] Optionally, in some embodiments, the second measurement beam set is determined based on at least one of the following:

[0097] The location information of the terminal;

[0098] The terminal's moving speed and direction of movement;

[0099] The distance between the terminal and the center point of the beam coverage;

[0100] The polarization direction supported by the receiving antenna of the terminal;

[0101] The satellite's ephemeris information, wherein the satellite is the network-side device or the satellite is used to forward the first signaling sent by the network-side device.

[0102] When determining the second measurement beam set based on the terminal's location information, the beams whose coverage area includes the terminal's location and the beams whose coverage area edge is close to the terminal's location can be determined as the second measurement beam set.

[0103] Optionally, in some embodiments, the second configuration information includes at least one of the following:

[0104] Beam index;

[0105] The mapping relationship between beam index and BWP;

[0106] The mapping relationship between beam index and the antenna polarization direction corresponding to the beam;

[0107] The mapping relationship between beam index and reference signal.

[0108] The mapping relationship between beam indices and BWPs can include at least one of the following: a one-to-one mapping relationship or a one-to-many mapping relationship. For example, one beam index corresponds to one BWP, or one beam index corresponds to multiple BWPs. The mapping relationship between beam indices and the antenna polarization direction corresponding to the beam can include at least one of the following: a one-to-one mapping relationship or a one-to-many mapping relationship. For example, one beam index corresponds to one polarization direction, or one beam index corresponds to multiple polarization directions.

[0109] Optionally, in some embodiments, the beams in the second measurement beam set do not have measurement priority, or the measurement priority of the beams in the second measurement beam set is determined based on at least one of the following:

[0110] The priority indicated by network-side devices;

[0111] The order in which the beams are arranged in the second measurement beam set;

[0112] The antenna polarization direction corresponding to the beam;

[0113] The frequency of the beam.

[0114] In this embodiment of the application, when determining the measurement priority of a beam based on the arrangement order of the beams in the second measurement beam set, the beams in the second measurement beam set can be set to decrease or increase in measurement priority from front to back.

[0115] When determining the priority of beam measurements based on the antenna polarization direction corresponding to the beam, beams with the same antenna polarization direction as the currently used beam can be given a higher measurement priority, while the remaining beams can be given a lower measurement priority.

[0116] When determining the priority of beam measurements based on beam frequency, beams that share the same frequency as the currently used beam can be assigned a higher measurement priority, while the remaining beams can be assigned a lower measurement priority.

[0117] Optionally, in some embodiments, before the terminal obtains the first signaling sent by the network-side device, the method further includes:

[0118] The terminal sends a first indication message to the network-side device, the first indication message being used to indicate at least one of the following: the terminal needs to perform beam measurement; or requests the network-side device to send the first signaling.

[0119] In this embodiment, if the terminal and the network-side device can communicate directly, the terminal can directly send the first indication information to the network-side device; if the terminal and the network-side device can communicate indirectly via satellite, the terminal can send the first indication information to the network-side device indirectly via satellite, that is, the terminal sends the first indication information to the satellite, and the satellite forwards the first indication information to the network-side device.

[0120] It should be understood that the terminal can trigger the sending of the first indication information when the beam measurement conditions are met. These beam measurement conditions can be agreed upon by the protocol or configured by the network-side equipment, and no further restrictions are made here.

[0121] Optionally, in some embodiments, before the terminal obtains the first signaling sent by the network-side device, the method further includes:

[0122] The terminal reports auxiliary information, which is used to assist the network-side device in sending the first signaling.

[0123] The auxiliary information includes at least one of the following: the location information of the terminal; the moving speed and moving direction of the terminal; and the polarization direction supported by the receiving antenna of the terminal.

[0124] In this embodiment, if the terminal and the network-side device can communicate directly, the terminal can directly send auxiliary information to the network-side device; if the terminal and the network-side device can communicate indirectly via satellite, the terminal can send auxiliary information to the network-side device indirectly via satellite, that is, the terminal sends auxiliary information to the satellite, and the satellite forwards the auxiliary information to the network-side device.

[0125] This application embodiment enables the network-side device to better determine the second measurement beam set suitable for the terminal by reporting auxiliary information through the terminal.

[0126] Furthermore, in some embodiments, the first configuration information further includes configuration information for the associated reference signal.

[0127] In this embodiment of the application, the reference signal may include a synchronization signal and PBCH block SSB and a channel state information reference signal (CSI-RS), etc.

[0128] To better understand this application, the following detailed explanation uses specific examples to illustrate the process by which a network-side device sends the first signaling to activate a terminal for beam measurement:

[0129] Example 1: The network-side device determines the set of beams that need to be measured for the terminal configuration based on the terminal's location information.

[0130] like Figure 5 As shown, the network-side device configures the beam set to be measured for the terminal as {beam 1, beam 2, beam 3} via the first signaling based on the terminal's location information, and the corresponding BWP information is {BWP 1, BWP 2, BWP3}. Here, beam 1 corresponds to BWP 1, beam 2 corresponds to BWP 2, and beam 3 corresponds to BWP 3.

[0131] The terminal sequentially switches to three BWPs to complete beam measurements and feeds back the measurement results to the base station. By receiving measurement feedback results from different BWPs and using the feedback information from the terminal, the network-side equipment can obtain the transmission performance of each beam.

[0132] Example 2: Different beams have different polarization information.

[0133] like Figure 6As shown, the network-side device configures the beam set to be measured for the terminal as {beam 1, beam 2} through the first signaling based on the terminal's location information. The corresponding antenna polarization information is {right-hand circular polarization, left-hand circular polarization}, where beam1 corresponds to right-hand circular polarization (RHCP) and beam 2 corresponds to left-hand circular polarization (LHCP).

[0134] The terminal adjusts the polarization direction of the receiving antenna to complete the beam measurement and feeds the measurement results back to the base station. The network transmission performance is improved based on the feedback information from the terminal.

[0135] Example 3: Different beams have different polarization information and different BWPs.

[0136] like Figure 7 As shown, the network-side device configures the set of beams to be measured for the terminal as {beam 1, beam 2, beam 3} via the first signaling, based on the terminal's location information. The corresponding antenna polarization information is {right-hand circular polarization, left-hand circular polarization}, and the corresponding BWP information is {BWP 1, BWP 2, BWP 3}. Specifically, beam 1 corresponds to right-hand circular polarization and BWP 1, beam 2 corresponds to left-hand circular polarization and BWP 2, and beam 3 corresponds to left-hand circular polarization and BWP 3.

[0137] Optionally, in some embodiments, BWP 1, BWP 2 and BWP3 are dynamically configured by the network-side device.

[0138] Example 4: Different beams have different polarization information and different BWPs.

[0139] like Figure 7 As shown, the network-side device configures the set of beams to be measured for the terminal as {beam 1, beam 2, beam 3} via the first signaling, based on the terminal's location information. The corresponding antenna polarization information is {right-hand circular polarization, left-hand circular polarization}, and the corresponding BWP information is {BWP 1, BWP 2, BWP 3}. Specifically, beam 1 corresponds to right-hand circular polarization and BWP 1, beam 2 corresponds to left-hand circular polarization and BWP 2, and beam 3 corresponds to left-hand circular polarization and BWP 3.

[0140] BWP 1 is a measurement-specific BWP in beam 1, BWP 2 is a measurement-specific BWP in beam 2, and BWP 3 is a measurement-specific BWP in beam 3.

[0141] Example 5: Different beams have different polarization information and different reference signals.

[0142] like Figure 7 As shown, the network-side device configures the set of beams to be measured for the terminal as {beam 1, beam 2, beam 3} via the first signaling based on the terminal's location information. The corresponding antenna polarization information is {right-hand circular polarization, left-hand circular polarization}, the corresponding BWP information is BWP 1, and the corresponding reference signals are {reference signal 1, reference signal 2, reference signal 3}. Specifically, beam 1 corresponds to right-hand circular polarization, BWP 1, and reference signal 1; beam 2 corresponds to left-hand circular polarization, BWP 1, and reference signal 2; and beam 3 corresponds to left-hand circular polarization, BWP 1, and reference signal 3.

[0143] Optionally, the aforementioned BWP 1 is a BWP specifically used for beam measurement within the cell.

[0144] In Example 6, the terminal determines the beam to be measured based on its own location.

[0145] like Figure 8 As shown, when the terminal is at location A, it requests beam measurement. The network-side device sends a first signaling message to activate the terminal to perform beam measurement, configuring the beams to be measured as {beam 1, beam 2, beam 3}, with corresponding antenna polarization information of {RHCP, LHCP} and corresponding BWP information of {BWP 1, BWP 2}. Due to the very large propagation delay in the NTN scenario, when the terminal receives the first signaling message, it has already moved from location A to location B. At this time, based on its own location information, the terminal only performs beam measurement on beam 1 and beam 2.
