Description

[0001] This disclosure is a divisional application of the Chinese application with application number 2022800004077, application date February 14, 2022, and invention name “A method, device and readable storage medium for transmitting system information”. Technical Field

[0002] The present disclosure relates to the field of wireless communication technologies, and in particular to a method, device and readable storage medium for transmitting system information. Background Art

[0003] In the research of wireless communication technology, satellite communication is considered to be an important aspect of the future development of wireless communication technology. Satellite communication refers to the communication conducted by radio communication equipment on the ground using satellites as relays. The satellite communication system consists of a satellite part and a ground part. The characteristics of satellite communication are: a large communication range; communication can be carried out between any two points as long as they are within the range covered by the radio waves emitted by the satellite; and it is not easily affected by land disasters (high reliability). As a supplement to the current ground cellular communication system, satellite communication can have the following benefits: First, it can achieve extended coverage. For areas that cannot be covered by the current cellular communication system or have high coverage costs, such as oceans, deserts, remote mountainous areas, etc., satellite communication can be used to solve communication problems. Secondly, emergency communication can be carried out. For example, in extreme cases such as disasters such as earthquakes that cause the cellular communication infrastructure to be unavailable, satellite communication can be used to quickly establish a communication connection. In addition, it can also provide industry applications. For example, for delay-sensitive services for long-distance transmission, satellite communication can be used to reduce the delay of service transmission.

[0004] It can be foreseen that in future wireless communication systems, satellite communication systems and terrestrial cellular communication systems will gradually achieve deep integration and truly realize the intelligent connection of all things.

[0005] However, in the scenario of satellite communication, the data transmission time is long due to the long signal transmission distance between the transmitter and the receiver. For transmissions with uplink and downlink relationships, it is possible to consider introducing Koffset to compensate for the transmission delay. Among them, at least cell-specific Koffset and user equipment-specific Koffset (UE-specific) are supported. The cell-specific Koffset is notified through the system information block (SIB), and as the satellite moves, the cell-specific Koffset may be updated. When the system information is updated, there is no limit on the time when the user equipment receives the system information during the system information change period (SI modification period). Therefore, in the scenario of non-terrestrial networks (NTN), there may be an ambiguous period, and the transmission of the user equipment will conflict during the ambiguous period.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and cannot be understood as limiting the present disclosure.

[0119] like Figure 1A As shown, a method for transmitting system information provided by an embodiment of the present disclosure can be applied to a wireless communication system 100, which may include but is not limited to a network device 101 and a user device 102. The user device 102 is configured to support carrier aggregation, and the user device 102 can be connected to multiple carrier components of the network device 101, including a primary carrier component and one or more secondary carrier components.

[0120] It should be understood that the above wireless communication system 100 can be applied to both low-frequency scenarios and high-frequency scenarios. Application scenarios of the wireless communication system 100 include, but are not limited to, long term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, worldwide interoperability for micro wave access (WiMAX) communication systems, cloud radio access network (CRAN) systems, future fifth-generation (5G) systems, new radio (NR) communication systems, or future evolved public land mobile networks (PLMN) systems, etc.

[0121] The user equipment 102 shown above may be a user equipment (UE), a terminal, an access terminal, a terminal unit, a terminal station, a mobile station (MS), a remote station, a remote terminal, a mobile terminal, a wireless communication device, a terminal agent or a user equipment, etc. The user equipment 102 may have a wireless transceiver function, and it may communicate (such as wireless communication) with one or more network devices 101 of one or more communication systems, and receive network services provided by the network device 101, where the network device 101 includes but is not limited to the base station shown in the figure.

[0122] Among them, the user equipment 102 can be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA) device, a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a user device in a future 5G network, or a user device in a future evolved PLMN network, etc.

[0123] The network device 101 may be an access network device (or access network point). Among them, the access network device refers to a device that provides network access functions, such as a radio access network (RAN) base station, etc. The network device may specifically include a base station (BS) device, or a base station device and a wireless resource management device for controlling the base station device, etc. The network device may also include a relay station (relay device), an access point, a base station in a future 5G network, a base station in a future evolved PLMN network, or an NR base station, etc. The network device may be a wearable device or a vehicle-mounted device.

[0124] For example, the network device 101 includes but is not limited to: a next-generation base station (gnodeB, gNB) in 5G, an evolved node B (evolved node B, eNB) in an LTE system, a radio network controller (radio network controller, RNC), a node B (node ​​B, NB) in a WCDMA system, a wireless controller under a CRAN system, a base station controller (base station controller, BSC), a base transceiver station (base transceiver station, BTS) in a GSM system or a CDMA system, a home base station (for example, home evolved nodeB, or home node B, HNB), a baseband unit (baseband unit, BBU), a transmission point (transmitting and receiving point, TRP), a transmitting point (transmitting point, TP) or a mobile switching center, etc.

[0125] Before introducing the scheme for transmitting system information provided by the present disclosure, a method for performing timing adjustment is first introduced.

[0126] The first method takes into account the long signal transmission distance between the sender and the receiver, which results in a long data transmission time. For transmission with uplink and downlink relationship, the relevant standardization discussion determined the introduction of Koffset (Koffset) parameters to compensate for the transmission delay.

[0127] The second method is to use TA (Timing Advance) to allow the terminal to send data packets in advance.

[0128] Reference Figure 1BAs shown, the downlink data packet sent by the base station on the nth downlink transmission unit reaches the downlink transmission unit on the terminal side after a certain transmission delay, and the uplink data packet sent by the terminal side on the nth uplink transmission unit has a specified TA value relative to the downlink data packet received on the nth downlink transmission unit, thereby allowing the base station side to achieve uplink and downlink timing alignment.

[0129] Or refer to Figure 1C As shown, the uplink and downlink timings on the base station side may not be aligned, and there is a specified frame timing offset between the nth downlink transmission unit and the nth uplink transmission on the base station side.

[0130] The present disclosure provides a method for transmitting system information. Figure 2 is a flow chart showing a method of transmitting system information according to an exemplary embodiment. Figure 2 As shown, the method includes:

[0133] Step S203, the user equipment 102 determines the effective time of the updated system information;

[0134] Step S204, the user equipment 102 starts to apply the updated system information at the effective time.

[0135] In some possible implementations, the updated system information includes an updated cell-specific Koffset.

[0136] In the disclosed embodiment, the network device sends updated system information to the user device, the user device receives the updated system information from the network device, determines the effective time of the updated system information, and starts to apply the updated system information at the effective time, so that the user device and the network device have a consistent understanding of the effective time of the updated system information, prevents conflicts in data transmission of the user device, and ensures effective data transmission between the user device and the network device.

[0145] In some possible implementations, such as Figure 5 As shown, the effective time corresponds to the end position of the system information modification period. In some possible examples, the system information modification period is periodic, and each system information modification period may correspond to a system information modification cycle.

[0146] In some possible implementations, such as Figure 6 As shown, the user equipment uses the cell-specific Koffset sent in the old system information before the system information takes effect, wherein the old system information is the previous system information of the updated system information, or is called the historical system information received at the closest receiving time to the receiving of the updated system information.

[0147] In some possible implementations, such as Figure 6 As shown, the new cell-specific Koffset sent in the updated system information is used after the effective time.

[0148] In the disclosed embodiment, a user device receives system information updated by a network device, determines the effective time of the updated system information, and starts to apply the updated system information at the effective time, so that the user device and the network device have a consistent understanding of the effective time of the updated system information, thereby preventing conflicts in data transmission of the user device and ensuring effective data transmission between the user device and the network device.
