The system may also include a core network part, such as an evolved packet system (Evloved Packet System, EPS), a 5G system (5GS), and the like.

First, some terms involved in this application are introduced and explained:

The terminal device involved in this embodiment 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 devices connected to a wireless modem. In different systems, the name of the terminal equipment may be different. For example, in a 5G system, the terminal equipment may be called User Equipment (User Equipment, UE). The wireless terminal device can communicate with one or more core networks (Core Network, CN) via the radio access network (Radio Access Network, RAN), and the wireless terminal device can be a mobile terminal device, such as a mobile phone (or called a "cellular "telephones) and computers with mobile terminal equipment, such as portable, pocket, hand-held, computer built-in or vehicle-mounted mobile devices, which exchange language and/or data with the radio access network. For example, Personal Communication Service (PCS) phone, cordless phone, Session Initiated Protocol (SIP) phone, Wireless Local Loop (WLL) station, Personal Digital Assistant, PDA) and other devices. Wireless terminal equipment can also be called system, subscriber unit, subscriber station, mobile station, mobile station, remote station, access point , remote terminal (remote terminal), access terminal (access terminal), user terminal (user terminal), user agent (user agent), and user device (user device), which are not limited in this embodiment of the application.

The network side device involved in this embodiment of the present application may be a base station, and the base station may include multiple cells that provide services for terminals. Depending on the specific application, the base station can also be called an access point, or it can be a device in the access network that communicates with the wireless terminal device through one or more sectors on the air interface, or other names. The network-side device can be used to exchange received air frames and Internet Protocol (Internet Protocol, IP) packets, and act as a router between the wireless terminal device and the rest of the access network, where the rest of the access network can include Internet Protocol (IP) communication network. The network side device can also coordinate attribute management of the air interface.

For example, the network-side device involved in the embodiment of the present application may be the network-side device (Base Transceiver Station) in Global System for Mobile communications (GSM) or Code Division Multiple Access (CDMA). , BTS), or the network side equipment (NodeB) in Wide-band Code Division Multiple Access (WCDMA), or the evolution in the long term evolution (LTE) system Evolutionary Node B (eNB or e-NodeB), 5G base station (gNB) in the 5G network architecture (next generation system), or Home evolved Node B (HeNB), relay node (relay node), home base station (femto), pico base station (pico), etc., are not limited in this embodiment of the present application. In some network structures, the network side device may include a centralized unit (centralized unit, CU) node and a distributed unit (distributed unit, DU) node, and the centralized unit and the distributed unit may also be arranged geographically separately.

One or more antennas can be used between the network side device and the terminal device for Multi Input Multi Output (MIMO) transmission. MIMO transmission can be Single User MIMO (Single User MIMO, SU-MIMO) or multi-user MIMO (Multiple User MIMO, MU-MIMO). According to the shape and number of root antenna combinations, MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO, or massive-MIMO, or diversity transmission, precoding transmission, or beamforming transmission, etc.

In the satellite communication system, two types of beams are distinguished, namely, the first type of beam and the second type of beam. The first type of beam can also be called random beam, and the second type of beam can also be called service beam. It does not provide services for connected state UEs, and the second type of beam can allow UEs to access and provide services for connected state UEs. The communication coverage of a satellite can be divided into multiple wave positions. The first type of beam can provide services for each wave position by periodically scanning each wave position. The service unit time is fixed, for example, 5 ms, and the UE in each beam position can periodically obtain the service of the first type of beam. The first type of beam has a narrow working bandwidth and does not provide services for connected UEs. The first type of beams can broadcast system information for UEs. Each beam of the first type can be distinguished and identified by a corresponding beam identifier.

The satellite system provides services for connected UEs through the second type of beams. One satellite can support multiple second-type beams, and the working frequency domain and bandwidth of each second-type beam can be different. The operating frequency domain and bandwidth of the second type of beam are also different from those of the first type of beam. The second type of beam is scheduled on demand, that is, according to whether there is a UE in a certain wave position that needs to access the service, the second type of beam is scheduled to serve the UE.

The satellite moves periodically with a fixed trajectory. One implementation of the coverage of the first type of beam is to irradiate the ground at a fixed angle, and the first type of beam identified by the beam identifier n will move and cover the ground at a fixed speed. Another implementation is that the satellite adjusts the irradiation angle to always illuminate the fixed position on the ground until the satellite moves out of the coverage area, that is, the first type of beam identified by the beam identifier n always covers the fixed position on the ground during the coverage period of the satellite.

Since the beam types serving connected and unconnected UEs are different, once the unconnected UE needs to access the satellite system, it needs to send a request message through the first type of beam to request network access. Information about the second type of beams that are accessed. Considering that after the UE sends an access request on the first type of beam n, it may need the next beam scanning period, the time before the first type of beam n is covered again, to obtain the information of the second type of beam that can be accessed by the network. The coverage of the type beam may move with the movement of the satellite, which may cause the UE to be at the edge of the first type beam n when sending an access request. When the first type beam n arrives again in the next beam scanning cycle, the UE It is no longer within the coverage of the first type of beam n. How to ensure that the UE can obtain information about the second type of beam that can be accessed through the first type of beam remains to be resolved.

Therefore, in the method for obtaining beam information in the embodiment of the present application, the UE acquires information about at least one second first-type beam that can obtain second-type beam information through the first first-type beam where the UE resides, and then Obtaining information about available second-type beams on a first-type beam and/or at least one second first-type beam on one of the first-type beams, so as to ensure that the UE learns the second-type beam that can be accessed through the first-type beam Information about beams.

Specifically, the satellite can determine one or more second first-type beams that will cover the first wave position in the next beam scanning period through the motion trajectory, where the first wave position is the first first-type beam that the UE currently resides on. The beam position covered by the beam, so as to notify the UE of the information of the second and first type of beams. After the UE sends an access request through the first and first type of beams, the first and first types of beams or the second and first types of beams notified by the network Class beams, carry the frequency domain information and/or time domain information of the second class beams serving the UE through system information or Media Access Control Control Element (MAC CE).

Information about class beams.

The following is divided into 500 wave positions by "preset satellite system, the dwell 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, and the beam index (identification) of the first type of beam 0-499, and the identifier of the second type of beam is 1-5" as an example, the specific implementation process of the method for acquiring beam information provided by the embodiment of the present application is described in detail.

Embodiment 1: The UE obtains the information of the second type of beam through the designated first type of beam.

The methods shown in Figure 3 include:

Step 300: The UE camps on the first first-type beam, presets the identifier of the first first-type beam as 15, and obtains system information on the first-type beam 15.

Wherein, the system information may include information about at least one second first-type beam for which the UE can obtain information about the second-type beam, 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 of the second first type of beam;

The identification of the satellite where the second first type beam is located, for example, the UE may move out of the coverage of the first first type beam of the satellite where the identification is the identification of the satellite where the second first type beam information can be obtained by the UE ;as well as

The frequency domain information of the second first type of beam, for example, the UE may move out of the coverage of the satellite where the first first type of beam is located, and the frequency domain information of the first type of beam is the second, first The frequency point of the class beam.

It is assumed that two beams of the second and first type are taken as an example in this embodiment, for example, the identifiers of the beams of the second and first type are 14 and 16 .

Step 301: The UE camps on the first first-type beam, presets the identifier of the first first-type beam as 15, and initiates an access request on the first first-type beam.

Step 302: After receiving the UE's access request through the first type of beam 15, the network allocates the second type of beam to the UE.

Step 303: The network can obtain the second first type beam 14, 16 of the second type beam information through the first type beam 15 and one or more UEs broadcasted by the system information in step 301, and send the information of the second type beam to UE.

Assume that the identifier of the allocated second type of beam is 2, where the information of the second type of beam may also include:

The identification of the first type of beam indicates the identification information of the first type of beam for which the network corresponding to the second type of beam receives the access request, and the second type of beam responds to the access request sent through the first type of beam The second type of beam, the identifier of the first type of beam is 15 in this embodiment.

If the second type of beam is the indication information of the second type of beam that responds to the access request sent by the current first type of beam, it can be carried implicitly or explicitly, and the implicit method can be to not carry the first type of beam identifier The display mode carries indication information, for example, when the second type beam information is sent through the first type beam 15, that is, one implementation mode does not carry the first type beam identifier, and the other implementation mode carries indication information. The indication information indicates that the second-type beam is a second-type beam that responds to sending an access request through the current first-type beam, or is notified by carrying an identifier of the first-type beam as 15 .

The satellite identifier. In this embodiment, the satellite identifier corresponds to the identifier of the satellite corresponding to when the UE sends the access request, that is, the identifier of the satellite where the first beam of the first type is located. If the network deduces that the UE has moved out of the range covered by the satellite, the satellite identifier may be the identifier of the next satellite covering this wave position (ie, the wave position currently being scanned by the first first-type beam).

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

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

Specifically, in this embodiment, the UE learns according to step 301 that information about the second type of beam can be obtained on the second first type beam 14, 16 and/or the first first type beam 15, and according to step 301 The time domain information of the second first type of beams and/or other information in the system information is used to know the arrival time of the second first type of beams 14 and 16 . The UE acquires related information of the second type of beam through the second first type of beam 14 , 16 and/or the first first type of beam when the second first type of beam 14 , 16 arrives.

That is to say, the UE always needs to try to obtain the related information of the second type of beam in the first type of beam that sends the access request and the second type of beam in the system information broadcast, or only according to the second type of beam in the system information broadcast. A type of beam obtains information related to a second type of beam.

When the first type of beams 14, 15, and 16 scan, the UE synchronizes to the corresponding first type of beam, monitors its PDCCH scheduling, and obtains the second type of beam information, wherein the second type of beam information is the second type of beam 2 Information.

It should be noted that once the UE obtains the second-type beam information, it stops trying to obtain the second-type beam information on other first-type beams. For example, the arrival time sequence of the three first-type beams is 14, 15, 16, UE failed to synchronize to the first type of beam 14 or did not obtain the information of the second type of beam, then the UE continued to synchronize to the first type of beam 15, if the UE successfully synchronized to the first type of beam 15 and obtained the second type of beam information, the synchronization to the first type of beam 16 is stopped.

It should be understood that in this embodiment, before sending the access request, the UE obtains system information on the first beam of the first type 15, where the system information may also include basic information of five beams of the second type or at least one second beam. Basic information of a type of beam (that is, the system information may include basic information of all second-type beams, or basic information of a second-type beam that may be scheduled to this wave position). The basic information of each second-type beam includes at least one of the following:

Identification of the second type of beam;

frequency domain information for the second type of beam; and

Time domain configuration information of the second type of beam.

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

In addition, optionally, before initiating the access request, the UE also obtains the configuration information of the relevant resources of the network that the UE requests to access the network through the system information of the first beam of the first type. A possible implementation is by sending a sequence on a resource configured by the network, for example: sending a specified preamble on a configured random access channel (Random Access Channel, RACH) resource.

As an optional embodiment, in step 303, the network can obtain the second first-type beams 14 and 16 of the second-type beam information through the first-type beam 15 and one or more UEs broadcasting system information in step 301, and The information of the second type of beam 2 is sent to the UE through the MAC CE.

In this embodiment, the MAC CE is scheduled through a physical downlink control channel (physical downlink control channel, PDCCH) scrambled by a preset radio network temporary identity (Radio Network Temporary Identity, RNTI). A possible implementation method is to use No Random Access Radio Network Temporary Identifier (RA-RNTI) scrambling.

The specific ways for MAC CE to carry the second type of beam information may include the following:

Mode 1-1: If the system information in step 301 has already broadcasted part of the access information of the second type of beam, the MAC CE may only carry the identifier of the second type of beam, and the UE can combine the second type of beam identifier with the system information to Obtain frequency domain information and/or time domain information related to the second type of beam;

Mode 1-3: If the system information in step 301 has already broadcasted part of the access information of the second type of beam, such as broadcasting the time domain information, then the MAC CE may only carry the identity and/or frequency domain information of the second type of beam , the UE can obtain the time domain information related to the second type of beam through the identifier of the second type of beam combined with system information;

Mode 1-4: If the system information in step 301 does not carry part of the information of the second type of beam, then the MAC CE carries the identity of the second type of beam and/or the frequency domain information corresponding to the second type of beam and/or the The time domain information corresponding to the second type of beam.

As another optional embodiment, in step 303, the network can obtain the second first type beams 14, 16 of the second type beam information through the first type beam 15 and one or more UEs broadcasting the system information in step 301, The information of the second type of beam 2 is sent to the UE through system information.

Mode 2-3: If the system information in step 301 has already broadcasted part of the access information of the second type of beam, for example, time domain information, then the system information may only carry the identifier and/or frequency of the second type of beam at this time. domain information, the UE can obtain the time domain information related to the second type of beam through the identification of the second type of beam combined with the partial information broadcasted by the system information to access the second type of beam.

Mode 2-4: If the system information in step 301 does not carry part of the information of the second type of beam, then 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 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 of beam may also include indication information that the second type of beam is about to serve or indication information that the second type of beam is currently serving.

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

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

The scanning cycle offset N of the second first type of beam appears, that is, the UE sends a request message to the first first type of beam in the scanning cycle n, and the UE is after the interval N or N-1 scanning cycles, that is, the n+Nth The information of the second type beams is obtained for the second first type beams of +1 or n+N scanning period. For example: N=1 in this embodiment. The second beam of the first type appears in the scanning period of the N+1th beam of the first type, that is, in the next scanning period.

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

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

The order of appearance of the first type of beams, for example, in this embodiment, 500 first type of beams appear in order of index index, that is, 0, 1, 2, ..., 499 sequentially scan and appear.

The scanning cycle offset N of the second first type of beam appears, that is, the UE sends a request message to the first first type of beam in the scanning cycle n, and the UE is after the interval N or N-1 scanning cycles, that is, the n+Nth The information of the second type beams is obtained for the second first type beams of +1 or n+N scanning period. For example: N=1 in this embodiment. The second beam of the first type appears in the scanning period of the N+1th beam of the first type, that is, in the next scanning period.

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

Method 1: The offset of the time domain information of the second first type beam 14, 16, the arrival time of the first type beam 14, 16, the time offset between the second first type beam and the first first type beam The amount offset, that is, the arrival time of the first first-type beam is T, then the second first-type beam arrives after T+offset time.

Method 2: The time offset between the second first type beam and the first first type beam in the same scanning period, that is, the first first type beam T time arrival in the same scanning period, the second first type beam The beams of the first type arrive after the arrival time of the first beam of the first type T+offset time, and the arrival moments of the beams of the first type 14 and 16 are known.

Mode 3: According to the SSB pattern of the second first type beam 14, 16 in the time domain information of the second first type beam 14, 16, the arrival time of the first type beam 14, 16 is obtained.

Method 4: The arrival time of the first type beams 14 and 16 is obtained according to the number of the first type beams broadcasted by the system information or the period of the first type beams, the order of appearance of the first type beams, the duration of the first type beams, etc.

Method 5: According to the number of beams of the first type broadcasted by the system information or the period of the beams of the first type and the position of the SSB pattern of the second first type beams 14, 16 in the time domain information of the second first type beams 14, 16 , to know the moment of arrival of the beams 14, 16 of the first type.

Method 6: The SSB pattern of the satellite where the second first type beam is located (including the period and/or the specific SSB occurrence position), and/or the synchronization deviation between the satellite where the second first type beam is located and the satellite where the first first type beam is located ( slot boundary alignment deviation or SFN boundary alignment deviation (symbol alignment deviation) determines the appearance time of the second first type of beam on its satellite.

It should be noted that, by adopting the above method 1, the UE can acquire the related information of the second type of beam through the corresponding first type of beam according to the corresponding time.

For any of the foregoing manners 2 to 5, the UE always acquires related information of the second type of beams through the first type of beams 14 , 16 , and/or 15 in the next beam scanning period. In another optional manner, if step 301 also includes the scanning period offset N of the occurrence of the second first type of beam, for example, N is 2, then the UE determines that the second scanning period after the current scanning period passes The beams of the first type 14, 16, and/or 15 acquire information related to the beams of the second type.

It should also be noted that, one implementation is that the UE always needs to try to obtain the related information of the second type beam on the first first type beam that sends the access request and the second first type beam on which the system information is broadcasted, that is, even if The second and first-type beams broadcasted by the system information do not contain the identifier of the first and first-type beams, and the UE also tries to obtain related information of the second-type beams in the first and first-type beams; another implementation method is that the UE only uses the The second first type beam of the system information broadcast obtains the second type beam related information, if the network wants the UE to obtain the second type beam related information through the first first type beam, the second first type beam needs to contain the first first type beam The type beam identifier, that is, the second first type beam is equal to the first first type beam identifier.

Embodiment 2: UE access success or abnormal scenario

Success scenario: After the UE obtains the information of the second type of beam according to Embodiment 1 above, it determines the frequency domain information of the second type of beam and/or its occurrence time domain information. The UE searches for the corresponding frequency point of the second type of beam at the corresponding moment, and synchronizes to the frequency point to obtain corresponding system information to access the second type of beam. Wherein, the frequency domain information may be the frequency domain position of the SSB.

Abnormal scenario: Before obtaining the second type of beam information or when obtaining the second type of beam information, the UE may also obtain the effective interval information T' through the system information of the first type of beam or MAC CE, that is, the effective time of the second type of beam, When the valid time expires, if the UE fails to search for the second type of beam or fails to access the second type of beam, the UE considers the access failure. The specific implementation method is as follows:

The UE starts a timer when obtaining the second type of beam information; or,

The UE starts the timer when it initiates the access request; or,

Start the timer when the UE starts to search for the second type of beam; for example: if the information of the second type of beam carries the arrival time offset offset of the second type of beam, start searching for the second type of beam at the arrival time of the second type of beam , thus starting the timer. or,

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

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

The duration of the timer is the effective interval of the second type of beam, for example: the timer duration is T', when the UE successfully synchronizes to the second type of beam 2, or successfully accesses the second type of beam 2, or successfully obtains the second If there is no beam-like information, the timer T' is turned off; otherwise, the access is considered to be failed when the timer expires.

The foregoing method in the embodiment of the present application is also applicable to a scenario where the satellite coverage moves relative to the ground, and the satellite coverage moves with the ground.
