Detailed Description
In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be described in further detail with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Some terms in the embodiments of the present application are explained below to facilitate understanding by those skilled in the art.

(2) In the embodiments of the present application, the term "plurality" means two or more, and other terms are similar thereto.
(3) "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
(4) The network device is a device for providing a wireless communication function for the terminal, and includes but is not limited to: a gbb in 5G, a Radio Network Controller (RNC), a Node B (NB), a Base Station Controller (BSC), a Base Transceiver Station (BTS), a home base station (e.g., home evolved node B or home node B, HNB), a BaseBand Unit (BBU), a transmission point (TRP), a Transmission Point (TP), a mobile switching center (msc), and the like. The base station in the present application may also be a device that provides a terminal with a wireless communication function in other communication systems that may appear in the future. In the embodiments of the present application, a "base station" is described as an example.
(5) A terminal is a device that can provide voice and/or data connectivity to a user. For example, the terminal device includes a handheld device, an in-vehicle device, and the like having a wireless connection function. Currently, the terminal device may be: a mobile phone (mobile phone), a tablet computer, a notebook computer, a palm top computer, a Mobile Internet Device (MID), a wearable device, a Virtual Reality (VR) device, an Augmented Reality (AR) device, a wireless terminal in industrial control (industrial control), a wireless terminal in self-driving (self-driving), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety (transportation safety), a wireless terminal in smart city (smart city), or a wireless terminal in smart home (smart home), etc.
(6) A beam may correspond to a cell or a carrier or a fractional Bandwidth (BWP). In the NR cell, the bandwidths of different BWPs are different, the configuration parameters of other physical layer channels/signals of each BWP are usually configured independently, and the network device may configure different BWPs to the terminal, so that the uplink and downlink bandwidths used by the terminal are variable.
The beams referred to in the embodiments of the present application include a "first beam" and a "second beam," the second beam having a larger coverage than the first beam, and a coverage of the first beam may be within a coverage of the second beam or may be outside the coverage of the second beam. One first beam may be designated as a downlink beam or an uplink beam, or one first beam may comprise a downlink beam and an uplink beam, and the downlink beam and the uplink beam jointly form a cell. One second beam may be designated as a downlink beam or an uplink beam, or one second beam may comprise a downlink beam and an uplink beam, and the downlink beam and the uplink beam jointly form a cell.
In the embodiment of the present application, one first beam may be designated as an uplink beam, and may also be designated as a downlink beam, where one downlink beam may correspond to a plurality of uplink beams.
The first beam may also be referred to as a spot beam, and the second beam may also be referred to as a broad beam. In some embodiments of the present application, the first beam is referred to as a spot beam and the second beam is referred to as a broad beam.
Fig. 1 illustrates a schematic diagram of a double coverage of a wide beam and a spot beam in a satellite communication system. Here, cell 1, cell 2 and cell 3 (shown as dashed oval boxes in the figure) correspond to the wide beam coverage, and cells a to k (shown as solid oval boxes in the figure) correspond to the spot beam coverage, and the wide beam and spot beam coverage is shown in the figure. Cell a, cell b and cell c correspond to the coverage of the user plane high speed transmission beam 1 (i.e. spot beam 1) in the cell, cell d, cell e and cell f correspond to the coverage of the user plane high speed transmission beam 2 (i.e. spot beam 2) in the cell, cell g and cell h correspond to the coverage of the user plane high speed transmission beam 3 (i.e. spot beam 3) in the cell, and cell i, cell j and cell k correspond to the coverage of the user plane high speed transmission beam 4 (i.e. spot beam 4) in the cell.
The coverage range of the wide beam is large, the service duration is long, but the signal strength is relatively weak; the spot beam coverage is small, the service duration is short, but the signal gain is relatively large.
In a scenario of dual-layer coverage of beams, the data transmission capability of a wide beam is weak, resulting in a long access time of a UE (terminal), and the access capacity provided is limited due to a large coverage of the wide beam and limited band resources. While spot beams have strong data transmission capability, but the duration and coverage are variable, and are unstable to both UE access and data service, so that access is usually provided by wide beams and high-speed data transmission is provided by narrow beams. In order to provide services for more UEs (terminals), beam hopping (i.e., access between different beams) is often required to provide data transmission for UEs in different locations. The scheme enables the access capacity of the UE to be limited, and when the data volume of the UE is not large, the spot beams are not fully utilized.
The embodiment of the application provides an access method and equipment. In the embodiment of the present application, the network device sends the configuration information of the first beam (or called spot beam) to the terminal, so that the terminal can select the first beam meeting the access requirement according to the configuration information of each first beam and the access requirement to access, thereby ensuring the reliability of the access of the first beam and improving the utilization rate of the first beam.
The embodiment of the application can be suitable for a satellite communication system and can also be suitable for a ground communication system. When the embodiment of the present application is applied to a satellite communication system, the "network device" in the embodiment of the present application may be a device such as a ground gateway station of a satellite; when the embodiment of the present application is applied to a terrestrial communication system, the "network device" in the embodiment of the present application may be a base station.
The access described in the embodiment of the present application may refer to an initial access of the terminal when the terminal is powered on, or may refer to an access of the terminal to the network in an idle state, and the beam selection and the access methods are the same.
Embodiments of the present application are described below with reference to the drawings.
Referring to fig. 2, in the information configuration method implemented at the network side according to the embodiment of the present application, a network device may send configuration information of a first beam (or called a spot beam) to a terminal. As shown, the method may include:
s201: the network device transmits a system message carrying beam configuration information indicating at least one of a direction, a frequency band, and a beam duration service time of the at least one first beam.
The beam configuration information may include configuration information of at least one first beam, wherein the configuration information of one first beam may include at least one of a direction, a frequency band, and a beam duration service time of the beam.
Wherein the direction of the beam may be represented by the angle of the beam. The beam duration service time refers to the time that the beam signal can last for stable service, and the terminal needs to determine whether the time is long enough to help the terminal select the beam meeting the access requirement for access. When applied to a satellite communication system, the beam duration service time is usually expressed in seconds, considering the transmission delay from the satellite to the ground. The beam service time here refers to the remaining service time of the beam, i.e. the time after receiving the message from the terminal, the network can continue to provide service in the beam direction and frequency band, and if in some occasions, the beam service time can also provide more detailed indications, such as the start time of the beam and the end time of the beam, and the interval between the two times is also equal to the beam duration service time. If the beam duration service time is short, the terminal denies access to the beam, which the terminal accesses only if the beam duration service time exceeds the required access time. The required access time length of the terminal can be preset, and the value of the required access time length can be obtained according to experience, or obtained through statistics, or obtained through testing.
In some embodiments, the network device may send a system message carrying the beam configuration information in a second beam (or a wide beam).
In other embodiments, the network device may send a system message carrying the beam configuration information on the first beam. When the beam indicated by the beam configuration information sent by the first beam includes at least one first beam different from the first beam sending the beam configuration information, that is, when the beam configuration information is sent in the first beam, at least one configuration information of the first beam other than the first beam is included, so that the terminal can select a beam from the first beam other than the first beam for access. For example, the network device sends beam configuration information on spot beam 1, which includes configuration information of spot beam 1 (including at least one of beam direction, frequency band, beam duration service time) and configuration information of spot beam 2.
In some embodiments, one first beam designated as a downlink may be paired with a plurality (at least two) of first beams designated as an uplink, and accordingly, the beam configuration information may further include correspondence information (i.e., pairing information) between the one first beam designated as the downlink and the plurality of first beams designated as the uplink.
S202: and the terminal receives the system message and acquires the beam configuration information carried in the system message.
The terminal can select the first beam meeting the access requirement for access according to the beam configuration information in the subsequent process.
Referring to fig. 3, a flowchart of an access method implemented by a terminal side according to an embodiment of the present application is shown. In the process, the terminal may select a first beam meeting the access requirement for access according to the beam configuration information.
As shown, the process may include:
s301: the terminal receives a system message sent by the network equipment, wherein the system message carries beam configuration information, and the beam configuration information indicates at least one of the direction, the frequency band and the beam duration service time of at least one first beam.
In this step, the terminal selects or resides on a beam to receive the system message sent by the network device. The selected or parked beam may be a first beam (or called spot beam) or a second beam (or called broad beam).
For example, when the terminal performs initial access or initiates access from an idle state, the following method may be adopted to acquire the beam configuration information:
mode 1: the terminal performs blind search on all possible frequency points, selects one beam with larger signal receiving intensity, receives system messages on the beam and acquires beam configuration information from the received system messages;
mode 2: the terminal resides on a second beam (or called wide beam) first, and receives the system message on the beam, and acquires the beam configuration information from the received system message;
mode 3: the terminal first resides on a first beam (or called spot beam), receives the system message on the beam, and acquires the beam configuration information from the received system message.
For the related content of the beam configuration information carried in the system message and the manner in which the network device sends the system message, reference may be made to the foregoing embodiments, which are not repeated here.
S302: and the terminal selects a first beam meeting the access requirement from the at least one first beam according to the configuration information of the at least one first beam.
In this step, a first beam satisfying at least one of the following access requirements may be selected from the at least one first beam:
the beam duration service time is not less than the time required by the access process;
the beam direction matches the terminal position and the satellite position.
The required access time length of the terminal can be preset, and the value of the required access time length can be obtained according to experience, or obtained through statistics, or obtained through testing.
In some embodiments, the terminal may obtain position information of itself based on a satellite positioning system (e.g., a positioning system such as GPS or beidou), obtain satellite position information based on ephemeris information, determine a matching beam direction according to the location of itself and the location of the satellite, and then select a first beam whose beam direction matches the direction from among the first beams indicated by the beam configuration information.
Selecting the first beam with the beam duration service time not less than the time required by the access process can ensure that the terminal has enough time to execute the access process of the beam so as to ensure the reliability of the access. The first beam whose beam direction matches the terminal position and the satellite position is selected, and the communication performance can be ensured.
In some embodiments, the terminal may perform a measurement on the first beam indicated by the beam configuration information to obtain the signal reception strength of the corresponding beam. If the number of the first beams meeting the access requirement selected by the terminal according to the configuration information of at least one first beam is at least two, one of the at least two first beams can be selected according to the signal receiving strength of the at least two first beams. For example, the first beam with the highest signal reception strength may be selected from the at least two first beams, so that the transmission performance after access may be ensured.
S303: the terminal initiates access on the selected first beam.
In some embodiments of the present application, a terminal is allowed to access a first beam (or spot beam) and also a second beam (or wide beam). The selection of the first beam access or the second beam access is based on the size of a data packet transmitted by the data service, if the data packet is a small data packet, the terminal can initiate access in the second beam, and if the data packet is a large data packet, the terminal can directly initiate access in the first beam and then perform a data transmission process.
Specifically, if the terminal determines that the data volume of the data packet to be transmitted is greater than a set threshold, according to the beam configuration information, selecting a first beam meeting an access requirement from at least one first beam indicated by the beam configuration information for access, so as to exert the characteristic of strong data transmission capability of spot beam and ensure the transmission performance of the data packet; and if the terminal judges that the data volume of the data packet to be transmitted is less than or equal to the set threshold, initiating access on the second beam so as to ensure the transmission reliability of the data packet by utilizing the characteristics of large coverage range and long service duration of the wide beam.
For example, when the terminal resides in a wide beam, the terminal is in an idle state, at this time, if there is a service demand, the terminal determines the size of a data packet of the service based on the service demand, if the size of the data packet of the service is smaller than a set threshold, the terminal initiates access in the wide beam and performs data transmission after access, and if the size of the data packet of the service is larger than or equal to the set threshold, the terminal initiates access in a spot beam and performs data transmission after access. The method for selecting the access spot beam by the terminal can be seen in the foregoing embodiments.
Further, when the terminal selects the spot beam access and the data transmission is finished, the spot beam connection can be released and the terminal returns to the wide beam for residing.
In some embodiments of the present application, the beam configuration information sent by the network device includes correspondence information between one first beam designated as a downlink beam and at least two first beams designated as uplink beams. That is, a first beam (or spot beam), designated as a downlink beam, may be paired with two or more first beams (or spot beams), designated as uplink beams. The terminal determines a beam set corresponding to a first beam where the terminal currently resides according to the corresponding relationship information after residing in the first beam which is designated as a downlink beam, wherein the beam set comprises the first beam which is designated as an uplink beam and corresponds to the first beam where the terminal currently resides, and the terminal selects one first beam which is designated as an uplink beam from the beam set for random access according to the position of the terminal or based on the signal receiving intensity.
As can be seen from the above description, in the above embodiments of the present application, the network side sends the beam configuration information to the terminal through the system message, where the beam configuration information indicates at least one of a direction, a frequency band, and a beam duration service time of at least one first beam, so that the terminal may select the first beam meeting the access requirement as needed for access, thereby improving the reliability of access.
When the embodiment of the application is applied to a satellite communication system, in the broadcast information of a satellite cell, the beam direction, the frequency configuration and the beam duration service time of a spot beam are notified in a system message, so that a terminal can select and access the beam based on the beam duration service time, the signal intensity, the data service requirement and the like.
