Abstract
Description
Synchronization method, device and storage medium
[0001] This disclosure claims priority to the Chinese patent application filed with the China Patent Office on September 6, 2023, with application number 202311146648.5 and application name “A Synchronization Method, Device and Storage Medium”, the entire contents of which are incorporated by reference into this disclosure. Technical Field
[0002] The present disclosure relates to the field of communication technology, and in particular to a synchronization method, device, and storage medium. Background Art
[0003] Beam hopping technology is increasingly being used in satellite communications as an effective resource allocation method. Satellite beam hopping can be divided into signaling beams and service beams. Signaling beams are responsible for broadcasting synchronization signals, system messages, and providing user equipment (UE) access services. Service beams are responsible for UE service scheduling and data transmission. To reduce overhead, synchronization signals and other signals are generally not transmitted within service beams.
[0004] After completing access and authentication in the signaling beam, the user device must switch to the service beam for data transmission and service interaction. In most cases, the satellite's signaling beam and service beam are different, and the time and frequency within the service beam are not necessarily synchronized with the signaling beam. Therefore, the user device must resynchronize after switching to the service beam.

For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.
[0130] In the embodiments of the present disclosure, the term "plurality" refers to two or more than two, and other quantifiers are similar thereto.
[0131] The terms "first," "second," and so forth in the embodiments of this disclosure are used solely for purposes of illustration and distinction between the objects being described. They are not ordered, do not represent a specific limit on the number of objects in the embodiments of this disclosure, and do not constitute any limitation on the embodiments of this disclosure. For example, if the first configuration information is the configuration information for the initial bandwidth part (BWP) of a service beam, and the second configuration information is the configuration information for the reference signal within the initial BWP, the terms "first," "second," and so forth are used solely to distinguish between the different configuration information, and do not indicate a difference in priority or importance between the two configuration information.
[0132] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure and not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present disclosure.
[0133] The embodiments of the present disclosure provide a synchronization method, apparatus, and storage medium, for enabling a user equipment to quickly obtain downlink synchronization after switching to a service beam.
[0134] Among them, the method and the device are based on the same application concept. Since the principles of solving problems by the method and the device are similar, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.
[0135] The network device involved in the embodiments of the present disclosure may be a satellite equipped with a base station function, and the satellite may be a low earth orbit (LEO) satellite.
[0136] The user equipment involved in the embodiments of the present disclosure may be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connection capabilities, or other processing devices connected to a wireless modem. The user equipment may also be referred to as a terminal device. A wireless terminal device may communicate with one or more core networks (CNs) via a radio access network (RAN). The wireless terminal device may be a mobile terminal device, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal device. For example, it may be a portable, pocket-sized, handheld, computer-built-in, or vehicle-mounted mobile device that exchanges voice and / or data with a radio access network. For example, personal communication service (PCS) phones, cordless phones, session initiated protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), and other devices. The wireless terminal device may also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote terminal device, an access terminal device, a user terminal device, a user agent, or a user device, but is not limited in the embodiments of the present disclosure.
[0137] FIG1 is a schematic diagram of an application scenario provided by an embodiment of the present disclosure. As shown in FIG1 , a satellite and a user device are included. The satellite can communicate with the user device via beam hopping.
[0138] FIG1 is only a schematic diagram of an application scenario. The synchronization method provided by the present disclosure can be applied not only to the above scenario, but also to other scenarios.
[0139] Hopping beams can be divided into signaling beams and service beams. Signaling beams hop periodically, broadcasting synchronization signals, system messages, and providing user equipment (UE) access services. Service beams hop on demand, scheduling services and transmitting data to UEs. UEs complete access and authentication within the signaling beam before entering the service beam for data transmission and service interaction.
[0140] Because signaling beams and service beams are generated by different antenna arrays, their time-frequency characteristics may differ. After a user device completes access within the signaling beam, it must be scheduled within the service beam. If the user device fails to achieve downlink time-frequency synchronization in a timely manner after switching to the service beam, it will be unable to interact with services. If time-frequency synchronization is not achieved for a long time, the user device may return to the signaling beam to synchronize. This cycle will increase the user device's access latency, or even successfully access but fail to receive service scheduling.
[0141] Based on the problems in the prior art, the present disclosure proposes the following concept: configure an initial BWP for the service beam and configure a reference signal for the initial BWP so that after the user equipment switches to the service beam, it can perform downlink synchronization according to the configuration information of the BWP and the configuration information of the reference signal.
[0142] The synchronization method provided by the present disclosure is introduced below in conjunction with specific embodiments.
[0143] FIG2 is a flow chart of a synchronization method provided by an embodiment of the present disclosure. As shown in FIG2 , the method includes:
[0144] S201: A network device determines first configuration information.
[0145] The first configuration information may be configuration information of the initial BWP of the service beam.
[0146] The synchronization signal block (synchronization signal and PBCH block, SSB) signal is not transmitted in the initial BWP.
[0147] The initial BWP may be used to transmit a reference signal.
[0148] The reference signal may be a periodic channel state information reference signal (CSI-RS) or a periodic tracking reference signal (TRS) or other new reference signals that can be used for synchronization.
[0149] In one possible implementation, the network device may determine the first configuration information based on frequency domain information related to the signaling beam, or may determine the first configuration information based on other frequency domain information, which is not limited in this disclosure.
[0150] In a possible implementation manner, the first configuration information may include a bandwidth indication parameter and a frequency domain position indication parameter of the initial BWP.
[0151] The bandwidth indication parameter may directly indicate the bandwidth of the initial BWP or may indirectly indicate the bandwidth of the initial BWP. When indirectly indicating the bandwidth of the initial BWP, the bandwidth indication parameter may be a parameter representing the relationship between the bandwidth of the initial BWP and the known bandwidth.
[0152] For example, the bandwidth indication parameter may be 5, which directly indicates that the bandwidth of the initial BWP is 5 MHz.
[0153] In another example, the bandwidth indication parameter may be n, which may be used to indicate that the bandwidth of the initial BWP is 1 / n of the PBCH bandwidth in the signaling beam, where n may be 1, 2, 4, 8, etc.
[0154] For example, if n is 2 and the PBCH bandwidth in the signaling beam is 3.6 MHz, the bandwidth of the initial BWP is 1.8 MHz.
[0155] The frequency domain position indication parameter may directly indicate the frequency domain center position or the frequency domain starting position of the initial BWP, or may indirectly indicate the frequency domain center position or the frequency domain starting position of the initial BWP.
[0156] When the frequency domain center position of the initial BWP is indirectly indicated, the frequency domain position indication parameter can be the offset between the frequency domain center position of the initial BWP and the known frequency point. The frequency domain center position of the initial BWP can be determined based on the frequency domain position indication parameter and the known frequency point.
[0157] For example, when the frequency domain position indication parameter is 0 and the known frequency point is the frequency domain center position of the PBCH in the signaling beam, it can be determined that the frequency domain center position of the initial BWP is the same as the frequency domain center position of the PBCH in the signaling beam.
[0158] When the frequency domain starting position of the initial BWP is indirectly indicated, the frequency domain position indication parameter can be the offset between the frequency domain starting position of the initial BWP and the known frequency point. The frequency domain starting position of the initial BWP can be determined based on the frequency domain position indication parameter and the known frequency point.
[0159] S202: The network device determines second configuration information.
[0160] The second configuration information is the configuration information of the reference signal in the initial BWP.
[0161] In a possible implementation, the second configuration information may include a period, a time domain position, and a reference signal sequence of the reference signal.
[0162] FIG3 is a schematic diagram showing the position of an initial BWP and a reference signal transmitted therefrom according to an embodiment of the present disclosure, wherein the reference signal has a period of T and a bandwidth of the initial BWP of 20 physical resource blocks (PRBs).
[0163] The reference signal can adopt a comb structure and can support comb factors 1, 2, 4, and 8.
[0164] The reference signal sequences of the reference signals transmitted in the initial BWP may be the same or different.
[0165] Since there is no SSB signal in the service beam, the half-frame indication of the service beam can be performed through the reference signal.
[0166] When the reference signal period is greater than the system frame length (10ms), the time domain position of the reference signal can be set to the first symbol at the beginning of the system frame. In this configuration, the user equipment can determine the start time of the system frame by detecting the reference signal.
[0167] When the reference signal period is less than the system frame length (10ms), the sequence of the reference signal configured at the first symbol at the start of the system frame is different from the sequences of reference signals configured at other positions. In this configuration, the user equipment can distinguish the reference signal configured at the first symbol at the start of the system frame by the reference signal sequence and determine the start time of the system frame based on the reference signal.
[0168] S203. The network device sends first configuration information and second configuration information to the user equipment through a signaling beam.
[0169] In other words, the user equipment receives the first configuration information and the second configuration information sent by the network device through the signaling beam.
[0170] The network device may send the first configuration information and the second configuration information simultaneously, or may send the first configuration information and the second configuration information separately.
[0171] In a possible implementation, the network device may send the first configuration information and the second configuration information to the user equipment in any of the following ways:
[0172] Method 1: The network device sends a system message to the user equipment through a signaling beam, where the system message includes the first configuration information and / or the second configuration information.
[0173] In other words, the user equipment receives a system message sent by the network device through a signaling beam, where the system message includes the first configuration information and / or the second configuration information.
[0174] The system message may be a system information block (SIB) message.
[0175] Method 2: The network device sends first downlink control information (DCI) to the user equipment through a signaling beam, where the first DCI includes first configuration information and / or second configuration information.
[0176] In other words, the user equipment receives the first DCI sent by the network device through the signaling beam, and the first DCI includes the first configuration information and / or the second configuration information.
[0177] Method 3: The network device sends a first radio resource control (RRC) signaling to the user equipment through a signaling beam, where the first RRC signaling includes first configuration information and / or second configuration information.
[0178] In other words, the user equipment receives the first RRC signaling sent by the network device through the signaling beam, and the first RRC signaling includes the first configuration information and / or the second configuration information.
[0179] S204. The user equipment performs downlink synchronization in the service beam according to the first configuration information and the second configuration information.
[0180] The user equipment determines the frequency domain position and bandwidth of the initial BWP according to the first configuration information. When the user equipment switches from the signaling beam to the service beam, it detects the reference signal according to the second configuration information under the initial BWP and performs downlink synchronization through the reference signal.
[0181] In the embodiment shown in Figure 2, the network device determines first configuration information, which is the configuration information for the initial BWP of the service beam, which is used to transmit a reference signal. The network device determines second configuration information, which is the configuration information for the reference signal. The network device sends the first and second configuration information to the user equipment via a signaling beam. After receiving the first and second configuration information sent by the network device via the signaling beam, the user equipment performs downlink synchronization on the service beam based on the first and second configuration information. In a time division duplexing (TDD) system, the service beam and the signaling beam have the same frequency. Therefore, by configuring the initial BWP for the service beam and the reference signal for the initial BWP, the user equipment can quickly achieve downlink synchronization after switching to the service beam.
[0182] Based on the embodiment shown in FIG2 , how to perform beam switching is described in detail below in conjunction with FIG4 and FIG5 .
[0183] FIG4 is a flow chart of another synchronization method provided by an embodiment of the present disclosure. As shown in FIG4 , the method includes:
[0184] S401: A network device determines first configuration information.
[0185] S402: The network device determines the second configuration information.
[0186] S403. The network device sends first configuration information and second configuration information to the user equipment through a signaling beam.
[0187] It should be noted that the execution process of S401 to S403 can refer to the execution process of S201 to S203, and will not be repeated here.
[0188] S404. The network device sends indication information to the user equipment via a signaling beam.
[0189] In other words, the user equipment receives the indication information sent by the network device through the signaling beam.
[0190] The indication information may be used to instruct the user equipment to switch from the signaling beam to the service beam.
[0191] The network device may send the indication information, the first configuration information, and the second configuration information at the same time, or may send the first configuration information and the second configuration information first, and then send the indication information.
[0192] In one possible implementation, the network device may send the indication information in any of the following ways:
[0193] Method 1: The network device sends a second DCI to the user equipment through a signaling beam, and the second DCI includes the information.
[0194] In other words, the user equipment receives the second DCI sent by the network device through the signaling beam, and the second DCI includes the information.
[0195] The second DCI may be the same as or different from the first DCI.
[0196] Beam switching can be indicated by DCI format 0_1 or 1_1.
[0197] In a possible implementation, a beam switching indication bit may be added to the DCI format, and the beam switching may be indicated by the value of the beam switching indication bit.
[0198] For example, if the beam switching indication bit is "0", it indicates a signaling beam, and if the beam switching indication bit is "1", it indicates a service beam. When the user equipment receives the second DCI in the signaling beam, and the beam switching indication bit in the second DCI is "1", it indicates that the user equipment needs to switch to the service beam; when the user equipment receives the second DCI in the service beam, and the beam switching indication bit in the second DCI is "0", it indicates that the user equipment needs to switch to the signaling beam.
[0199] Method 2: The network device sends a second RRC signaling to the user equipment through a signaling beam, where the second RRC signaling includes indication information.
[0200] The second RRC signaling may be the same as or different from the first RRC signaling.
[0201] In a possible implementation, a beam switching indication bit may be added to the second RRC signaling, and the beam switching may be indicated by the value of the beam switching indication bit.
[0202] For example, if the beam switching indication bit is "0", it indicates a signaling beam, and if the beam switching indication bit is "1", it indicates a service beam. When the user equipment receives the second RRC signaling in the signaling beam, and the beam switching indication bit in the second RRC signaling is "1", it indicates that the user equipment needs to switch to the service beam; when the user equipment receives the second RRC signaling in the service beam, and the beam switching indication bit in the second RRC signaling is "0", it indicates that the user equipment needs to switch to the signaling beam.
[0203] In other words, the user equipment receives the second RRC signaling sent by the network device through the signaling beam, and the second RRC signaling includes indication information.
[0204] S405. The user equipment switches from the signaling beam to the service beam according to the instruction information.
[0205] After receiving the indication information, the user equipment can switch from the signaling beam to the service beam.
[0206] S406. Perform downlink synchronization in the service beam according to the first configuration information and the second configuration information.
[0207] It should be noted that the execution process of S406 can refer to the execution process of S204, and will not be repeated here.
[0208] In the embodiment shown in FIG4 , a network device determines first configuration information, which is configuration information for an initial BWP for a service beam, and which is used to transmit a reference signal. The network device determines second configuration information, which is configuration information for a reference signal. The network device sends the first and second configuration information to a user device via a signaling beam. The network device sends indication information to the user device via the signaling beam. The user device switches from the signaling beam to the service beam based on the indication information. Downlink synchronization is performed on the service beam based on the first and second configuration information. In a time division duplexing (TDD) system, the service beam and the signaling beam have the same frequency. Therefore, by configuring an initial BWP for the service beam and a reference signal for the initial BWP, the user device can quickly achieve downlink synchronization after switching to the service beam.
[0209] FIG5 is a flow chart of another synchronization method provided by an embodiment of the present disclosure. As shown in FIG5 , the method includes:
[0210] S501: A network device determines first configuration information.
[0211] S502: The network device determines the second configuration information.
[0212] S503. The network device sends first configuration information and second configuration information to the user equipment through a signaling beam.
[0213] It should be noted that the execution process of S501 to S503 can refer to the execution process of S201 to S203, and will not be repeated here.
[0214] S504: The user equipment determines a first time.
[0215] The first moment may be the moment when the beam switching timer is reset.
[0216] The beam switching timer may be started at the moment when the user equipment completes all operations within the signaling beam.
[0217] For example, the user equipment can start the beam switching timer after completing all operations within the signaling beam. The timing duration of the beam switching timer is a preset duration. When the beam switching timer is cleared (that is, before reaching the first moment), if no indication information indicating beam switching is received, it can switch to the service beam at the first moment.
[0218] The user equipment has received the configuration information of the service beam before the first moment.
[0219] S505. The user equipment switches from the signaling beam to the service beam at the first moment.
[0220] S506. The user equipment performs downlink synchronization in the service beam according to the first configuration information and the second configuration information.
[0221] It should be noted that the synchronization process of S506 can refer to the synchronization process of S204, and will not be repeated here.
[0222] In one possible implementation, if the user equipment fails to obtain downlink synchronization within a preset time period after switching to the service beam, it returns to the signaling beam.
[0223] Exemplarily, after switching to the service beam, the user equipment starts a beam switching timer, and the timing duration of the beam switching timer is a preset duration. If downlink synchronization is not obtained when the timer is cleared, the signaling beam is returned after the timer is cleared.
[0224] The preset duration can be determined based on actual conditions, and this disclosure does not limit this.
[0225] In one possible implementation, the user equipment can start a beam switching timer after completing all operations within the service beam. The timing duration of the beam switching timer is a preset duration. When the beam switching timer is cleared, if no indication information indicating beam switching has been received, it can switch to the signaling beam.
[0226] In the embodiment shown in Figure 5, a network device determines first configuration information, which is configuration information for an initial BWP for a service beam. The initial BWP is used to transmit a reference signal. The network device determines second configuration information, which is configuration information for a reference signal. The network device sends the first and second configuration information to a user equipment via a signaling beam. The user equipment determines a first time and switches from the signaling beam to the service beam at the first time. Downlink synchronization is performed on the service beam based on the first and second configuration information. In a time division duplexing (TDD) system, the service beam and the signaling beam have the same frequency. Therefore, by configuring an initial BWP for the service beam and a reference signal for the initial BWP, the user equipment can quickly achieve downlink synchronization after switching to the service beam.
