Several terms which are referred to in this application are first introduced and explained:

the terminal device according to the embodiments of the present application may be a device that provides voice and/or data connectivity to a user, a handheld device with a wireless connection function, or other processing device connected to a wireless modem, etc. The names of the terminal devices may also be different in different systems, for example in a 5G system, the terminal devices may be referred to as User Equipment (UE). The wireless terminal device may communicate with one or more Core Networks (CNs) via a radio access Network (Radio Access Network, RAN), which may be mobile terminal devices such as mobile phones (or "cellular" phones) and computers with mobile terminal devices, e.g., portable, pocket, hand-held, computer-built-in or vehicle-mounted mobile devices that exchange voice and/or data with the radio access Network. Such as personal communication services (Personal Communication Service, PCS) phones, cordless phones, session initiation protocol (Session Initiated Protocol, SIP) phones, wireless local loop (Wireless Local Loop, WLL) stations, personal digital assistants (Personal Digital Assistant, PDAs), and the like. The wireless terminal device may also be referred to as a system, subscriber unit (subscriber unit), subscriber station (subscriber station), mobile station (mobile), remote station (remote station), access point (access point), remote terminal device (remote terminal), access terminal device (access terminal), user terminal device (user terminal), user agent (user agent), user equipment (user device), and the embodiments of the present application are not limited.

The network side device according to the embodiment of the present application may be a base station, where the base station may include a plurality of cells for providing services for a terminal. A base station may also be called an access point or may be a device in an access network that communicates over the air-interface, through one or more sectors, with wireless terminal devices, or other names, depending on the particular application. The network side device may be configured to exchange received air frames with internet protocol (Internet Protocol, IP) packets as a router between the wireless terminal device and the rest of the access network, which may include an Internet Protocol (IP) communication network. The network side device may also coordinate attribute management for the air interface.

For example, the network side device according to the embodiments of the present application may be a network side device (Base Transceiver Station, BTS) in a global system for mobile communications (Global System for Mobile communications, GSM) or code division multiple access (Code Division Multiple Access, CDMA), a network side device (NodeB) in a wideband code division multiple access (Wide-band Code Division Multiple Access, WCDMA), an evolved network side device (evolutional Node B, eNB or e-NodeB) in a long term evolution (long term evolution, LTE) system, a 5G base station (gNB) in a 5G network architecture (next generation system), a home evolved base station (Home evolved Node B, heNB), a relay node (relay node), a home base station (femto), a pico base station (pico), and the like.

The MIMO transmission may be 2D-MIMO, 3D-MIMO, FD-MIMO, or massive-MIMO, or may be diversity transmission, precoding transmission, beamforming transmission, or the like, depending on the form and number of the root antenna combinations.

In a satellite communication system, two types of beams, namely a first type of beam and a second type of beam, wherein the first type of beam can be called as an incident beam, the second type of beam can be called as a service beam, and the first type of beam does not provide service for a connected UE, and the second type of beam can allow the UE to access and provide service for the connected UE. The communication coverage area of one satellite can be divided into a plurality of wave positions, the first type wave beam can provide service for each wave position by periodically scanning each wave position, the first type wave beam in each period serves for a fixed unit time, such as 5ms, in each wave position, and the UE in each wave position can periodically obtain the service of the first type wave beam. The first type of beam has a narrower working bandwidth, does not provide service for the UE in a connected state, and can broadcast system information for the UE. Each first type of beam may be identified by a corresponding beam identification distinction.

The satellite system provides services to the connected UEs via the second type of beam. One satellite may support multiple second-type beams, each of which may differ in operating frequency domain, bandwidth, etc. The second type of wave beam is different from the first type of wave beam in working frequency domain and bandwidth, the second type of wave beam is scheduled according to need, namely, according to whether a certain wave position has UE to access service, the second type of wave beam is scheduled to serve the UE.

The satellite moves periodically with a fixed motion trajectory, and the coverage mode of the first type of beam is that the first type of beam, which irradiates the ground at a fixed angle and is identified by the beam identification n, moves at a fixed speed on the ground for coverage. Another implementation, i.e. the satellite adjusts the illumination angle, always illuminates the ground fixed position until the satellite moves out of coverage, i.e. the first type of beam identified with beam identification n always covers the ground fixed position during this satellite coverage.

Because the beam types for the connected state and the unconnected state are different, once the unconnected state UE needs to access the satellite system, a request message is required to be sent through the first type of beam to request network access, and the information of the second type of beam which can be accessed is obtained through the first type of beam. Considering that the UE may need to acquire the accessible second type of beam information transmitted by the network in the next beam scanning period after the UE transmits the access request on the first type of beam n, the coverage area of the first type of beam may be moved along with the movement of the satellite, so that the UE may be located at the edge position of the first type of beam n when transmitting the access request, and the UE is not already located in the coverage area of the first type of beam n when the first type of beam n arrives again in the next beam scanning period. How to ensure that the UE can obtain the information of the second type of beam which can be accessed through the first type of beam remains to be solved.

Therefore, in the method for acquiring the beam information in the embodiment of the present application, the UE acquires, through the resident first type beam, information of at least one second first type beam capable of acquiring information of the second type beam, and acquires information of the available second type beam on the first type beam and/or one first type beam in the at least one second first type beam, so as to ensure that the UE acquires, through the first type beam, related information of the accessible second type beam.

Specifically, the satellite may determine one or more second first type beams that will cover the first wave position in the next beam scanning period through the motion trail, where the first wave position is the wave position covered by the first type beam where the UE currently resides, so as to notify the UE of information of the second first type beam, and after the UE sends the access request through the first type beam, the UE carries, through the system information or the medium access control layer control unit (Media Access ControlControl Element, MAC CE), frequency domain information and/or time domain information of the second type beam serving the UE, and the like, on the first type beam or the second first type beam notified by the network.

The following describes the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems in detail with specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

In one possible implementation manner, in S101, specifically may include:

That is, in this embodiment, the information of at least one of the beams of the second first type carried in the system information is acquired by receiving the system information on one of the beams of the first type on which the UE resides.

In some embodiments, the first system information further carries at least one of the following:

the duration of the first type of beam; the duration may be the residence time at each wave position, for example: the dwell time of the first type of beam in each wave position is 5ms.

The total number of first type beams; for example: there are 500 beams of the first type.

That is, the UE sends the request message on the first type beam of the scanning period N, and the UE obtains the information of the second type beam on the second first type beam of the n+n+1 or n+n scanning period after the interval N or N-1 scanning periods.

In another possible implementation, before S101, the method further includes:

For example: the order of arrival times of the first type of beam 15 and the at least one second first type of beam 14, 16 is: the first type of beam 14, 15, 16, the UE continues to synchronize to the first type of beam 15 if the UE does not successfully synchronize to the first type of beam 14 or does not obtain information about the second type of beam 2, and stops continuing to synchronize to the first type of beam 16 if the UE successfully synchronizes to the first type of beam 15 and obtains information about the second type of beam 2.

That is, in this embodiment, after receiving the access request sent by the UE on the first type beam, the network side may allocate a second type beam available to the UE, and transmit information of the second type beam through system information or MAC CE.

In this embodiment, before receiving an access request initiated by the UE on one of the first type of beams where the UE resides, system information may be broadcast on the first type of beams, where the system information carries information of at least one first type of beams where the UE may obtain information of the second type of beams. When the network transmits the information of the second type of beam through the system information or the MAC CE, the system information or the MAC CE carrying the information of the second type of beam can be sent on one first type of beam where the UE resides and/or at least one first type of beam, so that the UE can acquire the information of the second type of beam available to the UE on one of the first type of beams.

In other alternative embodiments, S202 may specifically include:

Specifically, in this embodiment, the arrival time of the at least one beam of the second first type and/or the arrival time of the beam of the first type may be determined by time domain information of the at least one beam of the second first type and/or information carried in the first system information.

An identification of an associated first type of beam;

the identification of the satellite where the second type of beam is located;

frequency domain information of the associated first type of beam;

In summary, according to the method for acquiring beam information provided by the embodiment of the application, the UE acquires information of at least one second first type beam capable of acquiring second type beam information through the resident first type beam, and acquires information of the available second type beam on the first type beam and/or one first type beam in the at least one second first type beam, so that the UE is ensured to acquire relevant information of the accessible second type beam through the first type beam.

The specific implementation process of a method for acquiring beam information provided by the embodiment of the present application is described in detail below by taking "preset 500 wave positions of the satellite system, where the residence time of the first type of beam in each wave position is 5ms, then the scanning period of the first type of beam is 2.5s, the beam index (identifier) of the first type of beam is 0-499, and the identifier of the second type of beam is 1-5" as an example.

Example 1: the UE obtains second-type beam information through the designated first-type beam.

The method as shown in fig. 3 includes:

step 300: the UE camps on a first type beam, presets the identity of the first type beam as 15, and obtains system information on the first type beam 15.

The system information may include information about at least one second first type beam for which the UE may obtain the second type beam information, where the information about each second first type beam includes at least one of the following:

identification of the second first type of beam;

time domain information for the second first type of beam;

the identification of the satellite where the second first type beam is located, for example, the coverage area of the satellite where the UE may move out of the first type beam is located, where the identification is the identification of the satellite where the second first type beam where the UE may obtain the second type beam information;

the frequency domain information of the second first type beam, for example, the coverage area of the satellite where the first type beam is located may be moved out by the UE, where the first type beam frequency domain information is the frequency point of the second first type beam where the UE can obtain the second type beam information.

Assume in this embodiment that two beams of the second first type are taken as an example, for example, the second first type beams are identified as 14, 16.

Step 301: the UE resides in a first type beam, the identification of the first type beam is preset to be 15, and an access request is initiated on the first type beam.

Step 302: after the network receives the access request of the UE through the first type beam 15, a second type beam is allocated to the UE.

Step 303: the network may obtain a second first type beam 14, 16 of second type beam information via the first type beam 15 and one or more UEs broadcasting the system information in step 301, and send the information of the second type beam to the UEs.

Assuming that the identifier of the allocated second type of beam is 2, the information of the second type of beam may further include:

the identification of the first type of beam indicates that the network corresponding to the second type of beam receives the identification information of the first type of beam of the access request, and the second type of beam is the second type of beam of the access request sent by the first type of beam, in this embodiment, the identification of the first type of beam is 15.

If the second type of beam is the indication information of the second type of beam which responds to the access request sent by the current first type of beam, the implicit carrying can be the display carrying, and the implicit carrying can be the carrying of the first type of beam identification, and the display carrying indicates information, for example, when the second type of beam information is sent by the first type of beam 15, that is, one implementation carries no first type of beam identification, and the other implementation carries indication information, and the indication information indicates that the second type of beam is the second type of beam which responds to the access request sent by the current first type of beam, or is notified by carrying the first type of beam identification as 15.

The satellite identifier in this embodiment corresponds to the identifier of the satellite corresponding to the UE sending the access request, that is, the identifier of the satellite where the first type of beam is located. If the network pushes out that the UE is moving outside the range covered by the satellite, the satellite identification may be the identification of the next satellite covering this band (i.e., the band that the first type of beam is currently scanning).

The frequency domain information of the first type of beam in this embodiment corresponds to the frequency point of the first type of beam corresponding to when the UE sends the access request. If the network deduces that the UE moved to the range covered by the satellite, the frequency domain information of the first type beam may be the frequency domain information of the first type beam of the next satellite covering the wave position.

Step 304: the UE acquires information of a second type beam available to the UE on one first type beam in the first type beam and/or at least one second first type beam.

Specifically, in this embodiment, the UE knows, according to step 301, that the information of the second type of beam may be obtained on the second first type of beam 14, 16 and/or the first type of beam 15, and knows the arrival time of the second first type of beam 14, 16 according to the time domain information of the second first type of beam in step 301 and/or other information in the system information. The UE obtains second type beam related information via the second first type beam 14, 16 and/or the first type beam at the moment when the second first type beam 14, 16 arrives.

That is, the UE always needs to attempt to obtain the second type of beam-related information on the first type of beam transmitting the access request and the second type of beam broadcast by the system information, or just obtain the second type of beam-related information according to the second type of beam broadcast by the system information.

The UE synchronizes to the corresponding first type beam at the moment when the first type beams 14, 15, 16 are scanned, monitors the PDCCH scheduling of the first type beam, and obtains second type beam information, wherein the second type beam information is information of the second type beam 2.

It should be noted that, once the second type of beam information is obtained, the UE stops continuing to attempt to obtain the second type of beam information on other first type of beams, for example: the time sequence of the three first type beams is 14, 15 and 16 respectively, and if the UE does not successfully synchronize to the first type beam 14 or does not acquire the second type beam information, the UE continues to synchronize to the first type beam 15, and if the UE successfully synchronizes to the first type beam 15 and acquires the second type beam information, the UE stops to continue to synchronize to the first type beam 16.

It should be understood that in this embodiment, before sending the access request, the UE obtains the system information on the first type of beam 15, where the system information may further include basic information of 5 second type of beams or basic information of at least one second type of beams (i.e., the system information may include basic information of all second type of beams or basic information of a second type of beam that may be scheduled to this wave band). The basic information of each second type of beam comprises at least one of the following:

Identification of the second type of beam;

frequency domain information of the second type of beam;

time domain configuration information for the second type of beam.

Alternatively, before sending the access request, the UE obtains system information on the first type beam 15, where the system information does not contain the basic information of the second type beam.

In addition, optionally, before the access request is initiated, the UE further obtains configuration information of related resources of the UE requesting access to the network through system information of the first type beam. One possible implementation is by sending a sequence over a network configured resource, such as: the specified preamble is transmitted on the configured random access channel (Random Access Channel, RACH) resources.

As an alternative embodiment, in step 303, the network may obtain the second first type beam 14, 16 of the second type beam information through the first type beam 15 and the one or more UEs broadcasting the system information in step 301, and send the information of the second type beam 2 to the UEs through the MAC CE.

In this embodiment, the MAC CE is scheduled by a physical downlink control channel (physical downlink control channel, PDCCH) scrambled by a preset radio network temporary identity (Radio Network Tempory Identity, RNTI), one possible implementation being to use random access network temporary identity (Random Access Radio Network Temporary Identifier, RA-RNTI) scrambling.

The specific ways of carrying the second type of beam information by the MAC CE may include the following:

mode 1-1: if the system information in step 301 has already broadcast part of the information of the second type of beam, the MAC CE may only carry the identifier of the second type of beam, and the UE may obtain frequency domain information and/or time domain information related to the second type of beam by combining the second type of beam identifier with the system information;

mode 1-2: if the system information in step 301 has been broadcast to access part of the information of the second type of beam, for example, broadcast frequency domain information, the MAC CE may only carry the identifier of the second type of beam and/or time domain information, and the UE may obtain the frequency domain information related to the second type of beam by combining the identifier of the second type of beam with the system information;

modes 1 to 3: if the system information in step 301 has been broadcast to access part of the information of the second type of beam, for example, broadcast time domain information, the MAC CE may only carry the identifier and/or the frequency domain information of the second type of beam, and the UE may obtain the time domain information related to the second type of beam by combining the identifier of the second type of beam with the system information;

modes 1 to 4: if the system information in step 301 does not carry part of the information of the second type of beam, the MAC CE carries the identifier of the second type of beam and/or the frequency domain information corresponding to the second type of beam and/or the time domain information corresponding to the second type of beam.

As another alternative embodiment, in step 303, the network may obtain the second first type beam 14, 16 of the second type beam information through the first type beam 15 and the one or more UEs broadcasting the system information in step 301, and send the information of the second type beam 2 to the UEs through the system information.

The specific manner in which the system information carries the second type of beam information may include the following:

mode 2-1: if the system information in step 301 has already broadcast the partial information of the second type of beam, the system information may only carry the identifier of the second type of beam, and the UE may obtain the frequency domain information and/or the time domain information related to the second type of beam by combining the identifier of the second type of beam with the partial information of the second type of beam that is broadcast by the system information;

mode 2-2: if the system information in step 301 has already broadcast part of the information for accessing the second type of beam, for example, broadcast frequency domain information, then the system information may only carry the identifier of the second type of beam and/or time domain information, and the UE may obtain the frequency domain information related to the second type of beam by combining the identifier of the second type of beam with the part of the information for accessing the second type of beam broadcast by the system information;

Mode 2-3: if the system information in step 301 has already broadcast part of the information for accessing the second type of beam, for example, broadcast time domain information, then the system information may only carry the identifier of the second type of beam and/or frequency domain information, and the UE may obtain the time domain information related to the second type of beam by combining the identifier of the second type of beam with the part of the information for accessing the second type of beam broadcast by the system information.

Modes 2 to 4: if the system information in step 301 does not carry part of the information of the second type of beam, the system information carries the identifier of the second type of beam and/or the frequency domain information corresponding to the second type of beam and/or the time domain information corresponding to the second type of beam.

In addition, in addition to the above information, optionally, the basic information of the second type beam may further include indication information that the second type beam is about to serve or indication information that the current second type beam is serving.

As another alternative embodiment, the time domain information of the second first type beam may include at least one of:

the time offset between the second first type beam and the first type beam, that is, the arrival time of the first type beam is T, the second first type beam arrives at the time of t+offset;

The time offset between the second first type beam and the first type beam in the same scanning period is offset, namely the first type beam T arrives at the same scanning period, and the second first type beam arrives after the first type beam arrival time T+offset time;

the synchronization signal block SSB pattern of the second first type beam may include SSB period lengths and/or start positions of SSB occurrences within the period, such that the positions of the second first type beam occurrences within the first type beam scanning period may be determined. The scanning period offset N of the second first type beam, namely the UE sends a request message in the first type beam of the scanning period N, and the UE obtains the information of the second type beam after the interval N or N-1 scanning periods, namely the second first type beam of the n+n+1 or n+N scanning periods. For example: n=1 in this embodiment. The second first type beam appears in the n+1th first type beam scanning period, i.e. in the next scanning period.

SSB pattern of the satellite where the second first type of beam is located, the SSB pattern may include: the scanning period of the first type beam of the satellite, and the starting position of each first type beam in the period.

The synchronization deviation (slot boundary alignment deviation or SFN boundary alignment deviation symbol alignment deviation) of the satellite where the second first type beam is located and the satellite where the first type beam is located can include any one or more of SFN deviation, slot deviation and OFDM symbol deviation, but is not limited to the above

Optionally, the system information may further include at least one of the following:

the duration of the first type of beam, for example: in this example 5ms;

the total number of first type beams, for example: 500 in this embodiment;

the order of occurrence of the first type of beams, for example: in this embodiment, the 500 first type beams appear in the index order, that is, the 0,1,2, … …,499 order scan appears.

The scanning period offset N of the second first type beam, namely the UE sends a request message in the first type beam of the scanning period N, and the UE obtains the information of the second type beam after the interval N or N-1 scanning periods, namely the second first type beam of the n+n+1 or n+N scanning periods. For example: n=1 in this embodiment. The second first type beam appears in the n+1th first type beam scanning period, i.e. in the next scanning period.

In step 304, the manner of obtaining the arrival time of the second first-type beam 14, 16 according to the time domain information of the second first-type beam and/or other information in the system information in step 301 may include the following:

Mode 1: the time domain information of the second first type beams 14, 16 is offset, the arrival time of the first type beams 14, 16 is known, and the time offset between the second first type beams and the first type beams, that is, the arrival time of the first type beam is T, then the second first type beam arrives after the time of t+offset.

Mode 2: the time offset between the second first type beam and the first type beam in the same scanning period, that is, the first type beam T arrives at the time in the same scanning period, and the second first type beam arrives after the first type beam arrival time t+offset time, so as to obtain the arrival time of the first type beams 14, 16.

Mode 3: the arrival times of the first type beams 14, 16 are known from the SSB pattern of said second first type beams 14, 16 in the time domain information of the second first type beams 14, 16.

Mode 4: the arrival times of the first type beams 14, 16 are known according to the number of first type beams or the first type beam period and the first type beam appearance sequence, the first type beam duration and the like of the system information broadcast.

Mode 5: and acquiring the arrival time of the first type of beams 14, 16 according to the number of first type of beams or the first type of beam periods broadcasted by the system information and the SSB pattern occurrence positions of the second first type of beams 14, 16 in the time domain information of the second first type of beams 14, 16.

Mode 6: SSB pattern (including period and/or specific SSB occurrence position) of the satellite where the second first type beam is located, and/or synchronization deviation (slot boundary alignment deviation or SFN boundary alignment deviation symbol pair Ji Piancha) of the satellite where the second first type beam is located and the satellite where the first type beam is located, determines the occurrence time of the second first type beam at the satellite where the second first type beam is located.

It should be noted that, with the above mode 1, the ue may obtain, according to the corresponding time, the second-type beam related information through the corresponding first-type beam.

For any of the above modes 2-5, the UE always acquires the second type of beam related information through the first type of beams 14, 16, and/or 15 in the next beam scanning period. Alternatively, if step 301 further includes a scan period offset N, for example, N is 2, where the second first type beam occurs, the UE determines to acquire the second type beam related information through the first type beams 14, 16, and/or 15 in a second scan period subsequent to the current scan period.

It should also be noted that, in one implementation, the UE always needs to attempt to obtain the second type of beam related information on the first type of beam for transmitting the access request and the second type of beam for broadcasting the system information, i.e.: even if the second first type beam broadcast by the system information does not contain the identification of the first type beam, the UE tries to acquire the second type beam related information on the first type beam; another implementation is that the UE obtains the second type of beam related information only according to the second first type of beam broadcast by the system information, and if the network wants the UE to obtain the second type of beam related information through the first type of beam, the second first type of beam needs to include the first type of beam identifier, i.e. the second first type of beam is equal to the first type of beam identifier.

Example 2: UE access success or abnormal scenario

Successful scenario: after obtaining the second-type beam information according to the above embodiment 1, the UE determines the frequency domain information of the second-type beam and/or the time domain information of the second-type beam. And the UE searches the corresponding second type wave beam frequency point at the corresponding moment, and synchronizes to the frequency point to acquire corresponding system information and access the second type wave beam. Wherein, the frequency domain information may be the frequency domain position of the SSB.

Abnormal scene: before or when the UE obtains the second type of beam information, the UE may also obtain the effective interval information T' through the system information or MAC CE of the first type of beam, i.e. the effective time of the second type of beam, and if the effective time is overtime, the UE fails to search for the second type of beam or fails to access the second type of beam, the UE considers that the access fails. The specific implementation method is as follows:

the UE starts a timer when acquiring the second type beam information; or,

the UE starts a timer when initiating an access request; or,

starting a timer when the UE starts searching the second type of wave beams; for example: if the information of the second-class beam carries the second-class beam arrival time offset, searching the second-class beam at the second-class beam arrival time, and starting a timer. Or,

The UE starts a timer when each second first type wave beam or first type wave beam starts to acquire second type wave beam information; or,

the UE starts a timer when each second type beam or first type beam arrives.

The duration of the timer is the active interval of the second type of beam, for example: and if the time length of the timer is T ', the timer T' is closed when the UE successfully synchronizes to the second type beam 2, or successfully accesses the second type beam 2, or successfully obtains the information of the second type beam, and if the timer is overtime, the access is considered to be failed.

The method of the embodiment of the application is also applicable to scenes in which satellite coverage moves relative to the ground and the satellite coverage moves with the ground.
