Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

The application scenario of the embodiment of the present invention is that, as shown in Figure 1, due to the occlusion of the building 11, the base station 12 has a coverage hole in the beam direction 3 (the corresponding BWP is the original BWP), as shown in Figure 2, the coverage hole The existence of the terminal leads to poor received signal quality of the terminal. Therefore, the base station 12 repeatedly broadcasts the SSB of the beam direction 3 on the new BWP, and uses the combined diversity gain to improve the signal quality of the coverage hole. For the terminal, if it detects that the signal level of the BWP is higher than the set threshold, the terminal will autonomously initiate random access on the BWP. Therefore, in the above scenario, as the terminal moves, it is assumed that the coverage of beam direction 3 on the original BWP where the terminal is located is good enough. If the average is higher than the set threshold, the terminal will perform a random access process on the new BWP. Once a large number of terminals adopt the same method, the access resources on the new BWP will be exhausted, causing the access resources on the new BWP to waste of resources.

In order to avoid the above-mentioned problems, in related technologies, the network device broadcasts threshold information on the new BWP for the terminal to judge whether to switch from the new BWP to the original BWP for random access. When the signal quality of is higher than the corresponding threshold, the terminal switches to the original BWP to perform a random access process. In this process, how to set the threshold is very important. If the threshold is set low, the scope of the coverage hole on the original BWP is defined smaller. With a higher probability, the terminal will jump to the original BWP for random access. process, the access resources on the original BWP are exhausted, and the access resources on the new BWP are not fully utilized; or, the threshold is set higher, resulting in a larger definition of the scope of coverage holes on the original BWP, With a high probability, the terminal will perform a random access process on the new BWP, resulting in the exhaustion of access resources on the new BWP when the access resources on the original BWP are relatively sufficient.

Based on this, in various embodiments of the present invention, the network device determines the relevant threshold information more reasonably based on the relevant information of the random access process when the terminal switches from the first BWP to the second BWP, and uses A random access procedure is performed on the terminal judging whether to switch from the first BWP to the second BWP.

An embodiment of the present invention provides an information transmission method, which is applied to a network device. As shown in FIG. 3, the information transmission method provided by the embodiment of the present invention includes:

Step 301: Send a first request to a terminal.

Here, the first request is used to request to obtain related information of the random access procedure performed by the terminal from the first BWP to the second BWP.

In practical applications, the network device refers to a base station, such as a next-generation Node B (gNB) in a 5G system.

The network device repeatedly broadcasts the second information on the first BWP, where the second information is the SSB of the first direction. In practical application, the first direction may be the direction of the coverage hole of the network device, for example, the beam direction 3 shown in FIG. 1 is the direction of the coverage hole of the base station. Specifically, the above-mentioned first direction may be a direction of coverage holes on the second BWP.

Wherein, the coverage hole is relative to the terminal, and when the signal quality detected by the terminal is lower than the corresponding threshold, the terminal is considered to be in the direction of the coverage hole of the base station signal. By repeatedly broadcasting the SSB of the first direction on the first BWP by the network device, the signal quality of the first direction can be improved.

In practical applications, the conversion can also be understood as a transfer, that is, the terminal is transferred from the first BWP to the second BWP to perform a random access process, in other words, the terminal is transferred from the first BWP to the second BWP. A random access procedure is performed on the second BWP.

In actual application, the network device may send a first request, such as an RRC connection reconfiguration message, to the terminal through RRC signaling.

Based on this, in an embodiment, the sending the first request to the terminal includes:

Send the first request to the terminal through RRC signaling.

Step 302: Receive the relevant information reported by the terminal.

Specifically, after the terminal is connected to the network device and enters the connected state, it reports to the network device relevant information about the terminal switching from the first BWP to the second BWP to perform a random access process.

Here, the relevant information includes at least one of the following information:

The number of times the terminal switches from the first BWP to the second BWP to try random access can be obtained by counting the number of times the preamble is sent;

the location of said terminal before the transition took place and/or the time at which the transition occurred;

The signal quality of the cell measured by the terminal and/or the signal quality of the beam measured by the terminal before conversion occurs.

Wherein, in an embodiment, the signal quality may include at least one of the following:

RSRP;

RSRQ;

SINR.

Specifically, the cell signal quality may include at least one of the following:

Cell RSRP;

Cell RSRQ;

Cell SINR.

Specifically, the beam signal quality may include at least one of the following:

Beam RSRP;

Beam RSRQ;

Beam SINR.

Step 303: Determine first information according to the relevant information.

Here, the first information is used for the terminal to judge whether to switch from the first BWP to the second BWP to perform a random access procedure.

In practical applications, the network device determines the first information according to related information reported by at least one terminal.

The first information may be a corresponding threshold.

Here, the network device determines the first information according to the relevant information reported by at least one terminal, that is, determines the threshold for the terminal to judge whether to switch from the first BWP to the second BWP for random access procedure. The network device can define the size of the coverage hole where the terminal is located by setting the threshold accordingly. Specifically, when a lower threshold is defined to define a coverage hole with a smaller range, a higher threshold is defined to define a larger range. coverage holes. Referring to the example in Figure 4, the threshold 1 and threshold 2 set by the network device based on relevant information correspond to the coverage hole range 1 and the coverage hole range 2 in Figure 3, respectively, wherein the threshold 1 is lower than the threshold 2; correspondingly, the coverage hole range 1 is smaller than the coverage hole range 2, when the network device configures the threshold 2 as the first information, terminals located outside the coverage hole range 1 and on the edge of the coverage hole range 2 can also camp on the first BWP for random access process. Therefore, based on the relevant information reported by the terminal, the network device can more reasonably adjust the size of the coverage hole range, so as to reasonably adjust the number of terminals performing the random access process on the first BWP and the second BWP, and avoid either Access resources on the BWP are excessively consumed.

In practical application, the network device can determine the signal quality distribution in each time period within the coverage of the network device according to the relevant information reported by the terminal. Referring to Figure 5, according to the relevant information reported by terminals within the coverage area within a set time period, it can be determined that within the set time period, the signal quality at the corresponding positions within the coverage area of the base station in the figure are -60dBm, -60dBm, -63dBm, -68dBm, -80dBm, and -82dBm. In addition, in the coordinates at the bottom of Figure 5, the abscissa represents the signal quality, and the ordinate represents the number of terminals corresponding to the signal quality. After the base station knows the signal quality of the corresponding area within its coverage, it can adjust the threshold to block a certain number of terminals Defined within the scope of the coverage hole, so that these terminals reside on the first BWP for random access; or, define a certain number of terminals outside the scope of the coverage hole, so that these terminals switch to the second BWP The random access process is performed on the terminal, so as to control the number of terminals, and realize the balanced consumption of access resources on the first BWP and the second BWP.

In practical applications, at the initial stage of deploying the first BWP, the network device can determine a lower threshold, that is, define a smaller range of coverage holes, so that a large number of terminals will switch from the first BWP A random access process is performed on the second BWP, thereby increasing the number of terminals reporting related information, obtaining more related information, and determining more reasonable first information based on more related information.

In actual application, after determining the first information, the network device sends the first information to the terminal, so that the terminal judges whether to switch the BWP to perform the random access process according to the first information.

Based on this, in an embodiment, as shown in FIG. 6, the method may further include:

Step 304: Send the first information on the first BWP.

In order to allow all terminals within the coverage to receive the first information, the first information may be sent in a broadcast manner.

Based on this, in an embodiment, the sending the first information on the first BWP includes:

Broadcasting the first information on the first BWP through a broadcast message.

Here, when the network device broadcasts the first information through a broadcast message on the first BWP, the terminal receives the first information from the broadcast message to determine the corresponding threshold. When the signal quality detected by the terminal is greater than the corresponding threshold, the terminal determines not to perform the random access procedure on the first BWP, but switches to performing the random access procedure on the second BWP by frequency hopping.

Correspondingly, the embodiment of the present invention also provides an information transmission method, which is applied to a terminal. As shown in Figure 7, the information transmission method provided by the embodiment of the present invention includes:

Step 701: Receive a first request sent by a network device, where the first request is used for requesting to obtain related information about the terminal switching from the first BWP to the second BWP to perform a random access procedure.

Here, the network device sends a first request to the terminal, and the first request is used for requesting to obtain relevant information of the random access procedure performed by the terminal from the first BWP to the second BWP.

In an embodiment, the receiving the first request sent by the network device includes:

Receive a first request sent by the network device through RRC signaling.

The network device repeatedly broadcasts the second information on the first BWP, where the second information is the SSB of the first direction. In practical application, the first direction may be the direction of the coverage hole of the network device, for example, the beam direction 3 shown in FIG. 1 is the direction of the coverage hole of the base station. Specifically, the above-mentioned first direction may be a direction of coverage holes on the second BWP.

Wherein, the coverage hole is relative to the terminal, and when the signal quality detected by the terminal is lower than the corresponding threshold, the terminal is considered to be in the direction of the coverage hole of the base station signal. By repeatedly broadcasting the SSB of the first direction on the first BWP by the network device, the signal quality of the first direction can be improved.

Step 702: Report the relevant information to the network device; the relevant information is used for the network device to determine first information; the first information is used for the terminal to judge whether to switch from the first BWP to the The random access process is performed on the second BWP.

Specifically, after the terminal is connected to the network device and enters the connected state, it reports to the network device relevant information about the terminal switching from the first BWP to the second BWP to perform a random access process.

Here, the relevant information includes at least one of the following information:

The number of times the terminal switches from the first BWP to the second BWP to try random access can be obtained by counting the number of times the preamble is sent;

the location of said terminal before the transition took place and/or the time at which the transition occurred;

The signal quality of the cell measured by the terminal and/or the signal quality of the beam measured by the terminal before conversion occurs.

In one embodiment, as shown in FIG. 8, the method further includes:

Step 703: Receive the first information sent by the network device on the first BWP.

Further, in an embodiment, the receiving the first information on the first BWP includes:

receiving first information broadcast by the network device through a broadcast message on the first BWP.

Here, the network device sends the first information on the first BWP. When the network device broadcasts the first information through a broadcast message on the first BWP, the terminal in the idle state receives the first information from the broadcast message to determine the corresponding threshold. When the signal quality detected by the terminal is greater than the corresponding threshold, the terminal determines not to perform the random access procedure on the first BWP, but switches to performing the random access procedure on the second BWP by frequency hopping.
