Abstract
Description
Technical Field
[0001] This disclosure relates to beam switching technology, and more particularly to a beam switching method and apparatus, network equipment, terminal and storage medium. Background Technology
[0002] Beam-based handover occurs on different carriers or bandwidth portions (BWP) before and after the handover. Therefore, after the handover, the terminal cannot perform beam measurements and report on the resources previously used for the handover. This is because, firstly, handover on different frequency resources takes time and consumes power; secondly, it cannot guarantee that the channel quality after the handover will meet communication requirements. Therefore, a corresponding handover mechanism needs to be designed to adapt to beam-based handover scenarios. Summary of the Invention

[0090] Figure 2 This is a flowchart illustrating a beam switching method according to an exemplary embodiment, such as... Figure 2 As shown, the beam switching method of this disclosure includes the following processing steps:
[0091] Step 201: The network device sends beam switching information to the terminal based on the terminal's location information and channel measurement information. In another example, the network device may send switching information to the terminal based on other information.
[0092] The beam switching information includes beam switching requirements and / or target beam information. In this embodiment, when the beam switching information includes beam switching requirements but not target beam information, switching can be performed based on the frequency band information supported by the terminal or beam frequency band information obtained through measurement and detection. Of course, if the beam switching information includes target beam information, then switching directly to the target beam is performed.
[0093] In this embodiment of the disclosure, the network equipment includes base stations, relay stations, radio frequency remote units, etc., and may also include satellites as access sites or access relays, or the central control center in an unmanned aerial vehicle system.
[0094] In this embodiment of the disclosure, the terminal's location information can be reported by the terminal to the network device, or the network device can determine the terminal's location based on the communication signals between the terminal and the network device, or the network device can determine the terminal's location based on the cell information accessed by the terminal and the reverse signal transmission.
[0095] In this embodiment of the disclosure, when the network device receives information from the terminal indicating successful switching to the target beam, it releases the channel resources occupied by the terminal before switching to the target beam. Here, the channel resources occupied before switching to the target beam include the source beam resources used by the terminal for communication with the network device before the switch, as well as reserved communication resources related to the target beam specifically reserved for the terminal during the switch process. These reserved channel resources are used for switching information exchange between the terminal and the network device during the switch; for example, the terminal can use the reserved communication resources to send information to the network device regarding whether the switch was successful.
[0096] In this embodiment, the beam switching information further includes channel resource information reserved for the target beam. This allows the terminal to directly establish a connection with the network device based on the target beam's information, completing the beam switching. The channel resources reserved for the target beam can be used to transmit and receive resource information after beam switching.
[0097] When the target beam information includes two or more target beams, a priority is set for the two or more target beams so that the terminal switches to the highest priority beam first, and switches to the next lower priority beam if the switch fails, until the switch is successful or all target beams have been switched.
[0098] In this embodiment, the network device receives the information indicating successful target beam switching through reserved channel resources. As one implementation, the network device determines reserved channel resource information for the target beam based on at least one of the terminal's service information and the target beam's resource occupancy information. For example, based on the terminal's service bandwidth occupancy before switching, a suitable target beam for the terminal's current service is selected so that the current service is unaffected by the beam switching after the terminal completes the switch. When determining the target beam for the terminal, the occupancy status of the target beam must also be considered; that is, the remaining bandwidth of the target beam should be sufficient to support the terminal's service communication quality requirements.
[0099] In one embodiment of this disclosure, the network device can broadcast information about the reserved channel resources for each of the multiple beams supported by the network device via a broadcast channel. The terminal then receives this information via a broadcast message. In this way, the network device does not need to include the reserved channel resource information for the target beam in the beam switching information sent to the terminal. The terminal can determine the reserved channel resource information corresponding to the target beam based on the target beam. Thus, the network device receives the information indicating successful target beam switching through the reserved channel resources. Alternatively, the information about the multiple beams supported by the network device and the reserved channel resources for each beam can be pre-configured in the terminal, such as before the terminal leaves the factory. In this case, the beam and reserved channel resource information can be agreed upon in the protocol.
[0100] In one implementation of this disclosure, the network device can also receive the successful switching information of the target beam through the target beam. For example, the successful switching information can be received through the non-reserved channel resources of the target beam. That is, after the terminal successfully switches to the target beam, it can directly send the successful switching information of the target beam to the network device through the switched target beam; or, the network device confirms that the terminal has successfully switched to the target beam after receiving the service information sent by the terminal through the target beam.
[0101] In this embodiment of the disclosure, when the network device determines that no terminal switches to the target beam within a set time period after the terminal switches to the target beam, it releases the channel resources reserved for the target beam.
[0102] In this embodiment of the disclosure, the information of the target beam includes at least one of the following: carrier information of the target beam, BWP information, and identification information of the target beam.
[0103] Figure 3 This is a flowchart illustrating a beam switching method according to an exemplary embodiment, such as... Figure 3 As shown, the beam switching method of this disclosure includes the following processing steps:
[0104] Step 301: The terminal receives beam switching information sent by the network device and performs switching based on the beam switching requirements and / or target beam information in the beam switching information.
[0105] In this embodiment of the disclosure, when the beam switching information includes beam switching requirement information but not the target beam information, switching can be performed based on the frequency band information supported by the terminal or the beam frequency band information obtained through measurement and detection. If the beam switching information includes the target beam information, then switching is performed directly to the target beam.
[0106] When the target beam information includes two or more target beam information, the switch is made to the target beam based on the priority of the two or more target beams, or the switch is made randomly to one of the two or more target beams.
[0107] Step 302: The terminal sends a message to the network device that the target beam has been successfully switched, either through the switched target beam or the reserved resources of the target beam.
[0108] In this embodiment, the reserved channel resource information is carried within the beam switching information. Alternatively, the terminal receives information on the reserved channel resources for all beams supported by the network device via a broadcast message from the network device. Alternatively, the terminal is pre-configured with information on all beams supported by the network device and the reserved channel resource information for all beams. For example, this information can be defined in a protocol.
[0109] The following specific examples further illustrate the essence of the technical solutions in the embodiments of this disclosure.
[0110] In traditional cellular networks, different beams occupy the same frequency resources. Terminals do not need to switch frequencies or bandwidth during measurements, meaning the base station does not need to allocate additional resources to the terminal for reporting. However, in densely populated areas, to ensure the base station can schedule more users, it employs frequency division multiplexing, where multiple beams use different frequency resources. Especially in satellite communication systems, because a single satellite has a very wide coverage area and schedules a large number of users simultaneously, different beams can utilize different frequency resources to achieve coverage while ensuring system performance.
[0111] According to the embodiments of this disclosure, the base station sends a beam handover request to the terminal based on the location information and channel measurement information reported by the terminal, and indicates the target beam information and the reserved transmit / receive resource information after the handover. Upon receiving the message from the base station, the terminal begins handover to the carrier or BWP of the target beam. If the channel state of the target beam is determined to be good, communication is performed on the reserved resources of the target beam, and the terminal indicates to the base station that the handover is complete. After receiving the handover success information on the new beam or after performing measurements, the base station releases the resources of the source beam occupied by the terminal.
[0112] In this embodiment, the beam information refers to the beam's carrier or BWP information. The base station can directly indicate the destination beam information to the terminal, enabling the terminal to directly switch to the destination beam; or the base station can directly send beamindex information to the terminal, and the terminal, based on the previously configured beam index and beam correspondence, determines the destination beam information indicated by the base station. The previously configured beam index and beam correspondence can be received through system broadcast messages or pre-configured in the terminal according to protocol specifications.
[0113] In one embodiment, dedicated resource information is reserved on the frequency resources corresponding to each beam for the terminal's post-handover transmission and reception of information. This resource information is known to the terminal in advance, for example, as specified in the standard or obtained through broadcast information from the base station. If no other terminal switches to the target beam within a certain period of time, i.e., no successful handover message is received from the target beam within the set time, the dedicated resource information reserved for the target beam is released. For example, a timer can be set; in one embodiment, the start time can be based on when the base station sends a handover request to the terminal. In another embodiment, the timer can start based on the terminal's transmitted handover request plus the BWP handover capability reported by the terminal, such as the time required to switch BWPs.
[0114] In this fast-track embodiment, determining whether the channel state of the target beam is good can be done in one embodiment by considering that the measured Reference Signal Receiving Power (RSRP) is greater than a preset value, and then instructing the terminal to switch to that target beam. In another embodiment, if the RSRP of the target beam exceeds the RSRP value of the original beam by a set threshold, then the channel state of the target beam is considered good, and the terminal is instructed to switch to that target beam.
[0115] In another embodiment, when the base station indicates more than one destination beam, the priority can be indicated as needed, i.e., the order in which the destination beams are switched. Alternatively, the terminal can randomly select a destination beam for switching.
