Description

Technical Field

[0001] The present disclosure relates to the field of wireless communication technologies, and in particular to an information transmission and reception method, apparatus, device, and storage medium. Background Art

[0002] Network energy saving is a potential topic for Release 18. This topic examines how to reduce energy consumption in base stations and networks. One possible approach is to disable some of a base station's beams or carriers. For example, if a beam or carrier covers a small or no number of user equipment (UE), disabling that beam or carrier might be a viable option.

[0003] If a beam or carrier is turned off, UEs covered by that beam or carrier will need to switch / reselect to another beam or carrier, or another cell. However, abruptly turning off a beam or carrier may cause the UE to switch / reselect untimely, resulting in communication interruption, paging loss, or paging delay. Summary of the Invention

[0133] The embodiments of the present disclosure are now further described with reference to the accompanying drawings and specific implementation methods.

[0134] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0135] It should be noted that an embodiment of the present disclosure may include multiple steps; for the convenience of description, these steps are numbered; however, these numbers do not limit the execution time slots or execution order between the steps; these steps can be implemented in any order, and the embodiment of the present disclosure does not limit this.

[0136] Regarding network device disabling beams or carriers, it should be noted that a carrier may contain one or more beams. Therefore, if a network device only disables one beam, other beams on the same carrier may still be operating normally. If a network device disables a carrier, all beams on that carrier are also disabled.

[0137] The present disclosure provides an information transmission method, which is executed by a network device. The method can be executed independently or in combination with any other embodiment of the present disclosure. Figure 1 is a flow chart showing an information transmission method according to an exemplary embodiment. Figure 1 As shown, the method includes:

[0138] Step 101: Send a shutdown notification message, which includes a beam shutdown notification message and / or a carrier shutdown notification message. The beam shutdown notification message indicates that at least one beam will be shut down, and the carrier shutdown notification message indicates that at least one carrier will be shut down.

[0139] In one embodiment, the network device sends a shutdown notification message, which includes a beam-off notification message, and the beam-off notification message indicates that at least one beam is to be shut down.

After receiving the notification from the network device, the user device can prepare for switching / reselection before the beam and / or carrier is shut down, thereby reducing the probability of communication interruption, paging loss or paging delay caused by untimely switching / reselection of the user device.

[0143] The present disclosure provides an information transmission method, which is executed by a network device. The method can be executed independently or in combination with any other embodiment of the present disclosure. Figure 2 is a flow chart showing an information transmission method according to an exemplary embodiment. Figure 2 As shown, the method includes:

[0144] Step 201: In response to a shutdown notification message including a beam shutdown notification message, a beam shutdown notification message is sent through at least one SSB beam to be shut down, wherein the beam shutdown notification message indicates that at least one beam is to be shut down.

[0145] The beam-off notification message includes first indication information, and the first indication information indicates to turn off the SSB beam that is currently sending the beam-off notification message.

[0146] In one embodiment, in response to the shutdown notification message including the beam shutdown notification message, a beam shutdown notification message is sent via an SSB beam to be shut down. The beam shutdown notification message includes first indication information, which indicates that the SSB beam currently sending the beam shutdown notification message is to be shut down, i.e., indicates that the SSB beam with the same QCL type D as the SSB beam is to be shut down. In this embodiment, the beam shutdown notification message is only sent on the SSB beam to be shut down, and the beam shutdown notification is only effective for the SSB beam sending the beam shutdown notification message. In addition, the beam shutdown notification message does not include the SSB index information corresponding to the SSB beam to be shut down.

[0147] In one embodiment, in response to the shutdown notification message including the beam shutdown notification message, the network device sends a beam shutdown notification message via multiple SSB beams to be shut down. The beam shutdown notification message includes first indication information, which indicates that the SSB beam currently sending the beam shutdown notification message is to be shut down, that is, the SSB beam with the same QCL type D as the SSB beam is to be shut down. In this embodiment, the beam shutdown notification message is only sent on the multiple SSB beams to be shut down, and the beam shutdown notification is only effective for the SSB beam sending the beam shutdown notification message. In addition, the beam shutdown notification message does not include the corresponding SSB index information of the SSB beam to be shut down.

[0148] In one embodiment, in response to the shutdown notification message including a beam shutdown notification message, the network device sends a beam shutdown notification message via one or more SSB beams to be shut down. The beam shutdown notification message includes first indication information, where the first indication information indicates that the SSB beam currently sending the beam shutdown notification message is to be shut down. The beam shutdown notification message includes a 1-bit information bit. When the value of the information bit is 1, it indicates that the SSB beam will not be shut down; when the value of the information bit is 0, it indicates that the SSB beam will be shut down.

[0149] In the above embodiment, before shutting down the beam and / or carrier, the network device notifies the user device that the beam and / or carrier is going to be shut down. After receiving the notification from the network device, the user device can prepare for switching / reselection before the beam and / or carrier is shut down, thereby reducing the probability of communication interruption, paging loss or paging delay caused by untimely switching / reselection of the user device.

[0150] The present disclosure provides an information transmission method, which is executed by a network device. The method can be executed independently or in combination with any other embodiment of the present disclosure. Figure 3 is a flow chart showing an information transmission method according to an exemplary embodiment. Figure 3 As shown, the method includes:

[0151] Step 301: In response to a shutdown notification message including a beam shutdown notification message, the beam shutdown notification message is sent through the following beams, where the beam shutdown notification message indicates that at least one beam is to be shut down:

[0152] At least one SSB beam will be shut down, or

[0153] the at least one SSB beam to be disabled and at least one SSB beam not to be disabled, the non-SSB beam and the at least one SSB beam to be disabled belonging to the same carrier;

[0154] The beam-off notification message includes second indication information, and the second indication information indicates information of the at least one SSB beam to be turned off.

[0156] For example, at least one SSB beam to be shut down includes 3 SSB beams, and the carrier to which the 3 SSB beams belong includes a total of 8 SSB beams. The network device can send a shutdown notification message through the 3 SSB beams, wherein the shutdown notification message includes a shutdown beam notification message, and the shutdown beam notification message includes second indication information, and the second indication information indicates information of the 3 SSB beams to be shut down.

[0157] In one embodiment, in response to the shutdown notification message including a beam shutdown notification message, a beam shutdown notification message is sent via at least one SSB beam to be shut down and other non-shut down SSB beams in the carrier to which the SSB beam to be shut down belongs. The beam shutdown notification message includes second indication information indicating information about the at least one SSB beam to be shut down. In this embodiment, the beam shutdown notification message is sent not only on the SSB beam to be shut down but also on SSB beams not to be shut down in the same carrier.

[0158] For example, at least one SSB beam to be shut down includes 3 SSB beams, and the carrier to which the 3 SSB beams belong includes a total of 8 SSB beams. The network device can send a beam shut-down notification message through the 3 SSB beams. At the same time, the network device also sends a beam shut-down notification message on several of the other 5 beams belonging to the same carrier, wherein the beam shut-down notification message includes a beam shut-down notification message, and the beam shut-down notification message includes second indication information, and the second indication information indicates information of the 3 SSB beams to be shut down.

[0159] That is to say, when it is necessary to turn off the beam, the network device sends a beam-off notification message on the SSB beam to be turned off. Optionally, the network device can also send a beam-off notification message on other non-turned-off SSB beams, and the beam-off notification message indicates information of at least one SSB beam to be turned off.

[0160] It should be noted that when the second indication information indicates that all SSB beams on a carrier will be turned off, it is equivalent to turning off the carrier to which the above SSB beam belongs.

[0161] In the above embodiment, before shutting down the beam and / or carrier, the network device notifies the user device that the beam and / or carrier is going to be shut down. After receiving the notification from the network device, the user device can prepare for switching / reselection before the beam and / or carrier is shut down, thereby reducing the probability of communication interruption, paging loss or paging delay caused by untimely switching / reselection of the user device.

The network device then shuts down the SSB beam and the CSI-RS beam that has a QCL relationship with the SSB beam after a set duration T1. That is, when the network device shuts down an SSB beam, the CSI-RS beam that has a QCL relationship with the SSB beam is also shut down.

[0266] In the above embodiment, turning off the SSB beam means stopping sending the SSB and stopping sending the channel that uses the SSB as a transmission configuration indicator state (TCI-state).

In addition, the beam-off notification message does not include the SSB index information corresponding to the SSB beam to be turned off.

[0290] In one embodiment, a user equipment receives a beam-off notification message from a network device via one or more SSB beams. The beam-off notification message includes first indication information, which indicates that the SSB beam currently sending the beam-off notification message should be turned off. The beam-off notification message includes a 1-bit information bit. When the value of the information bit is 1, it indicates that the SSB beam will not be turned off; when the value of the information bit is 0, it indicates that the SSB beam will be turned off.
