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 FIG. 1 , due to the occlusion of the building 11 , a coverage hole appears in the base station 12 in the beam direction 3 (the corresponding BWP is the original BWP). As shown in FIG. 2 , the coverage hole is The existence of , leads to poor received signal quality of the terminal. Therefore, the base station 12 repeatedly broadcasts the SSB of beam direction 3 on the new BWP, and utilizes the combined diversity gain to improve the signal quality covering the hole. For the terminal, if the detected signal level of the BWP is higher than the set threshold, the terminal will initiate random access on the BWP autonomously. Therefore, in the above scenario, as the terminal moves, assuming that the coverage of beam direction 3 on the original BWP where the terminal is located is good enough, if the terminal residing on the new BWP detects the signal power of the new BWP If the level is higher than the set threshold, the terminal will perform a random access process on the new BWP. Once a large number of terminals take the same approach, the access resources on the new BWP will be exhausted, resulting in access to the new BWP. waste of input resources.

Based on this, in various embodiments of the present invention, the terminal does not perform a random access procedure on the first BWP, but receives the first information on the first BWP to determine the frequency point of the second BWP, and performs a random access procedure on the second BWP. The random access procedure is performed on the

An embodiment of the present invention provides a random access method, which is applied to a terminal. As shown in FIG. 3 , the random access method provided by the embodiment of the present invention includes:

Step 301: The random access procedure is not performed on the first BWP.

Step 302: Determine the frequency point of the second BWP by using the first information, and perform a random access process on the second BWP.

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

In step 301, the terminal camps on the first BWP and determines not to perform a random access procedure on the first BWP. Wherein, for the first BWP, the network device repeatedly broadcasts the second information on the first BWP; the second information is the SSB in the first direction.

Here, by repeatedly broadcasting the SSB covering the hole direction on the first BWP, the signal quality covering the hole direction can be improved.

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 the direction of the coverage hole on the second BWP.

Wherein, the coverage hole is relative to the terminal, 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.

In an embodiment, as shown in FIG. 4 , the terminal determines not to perform a random access procedure on the first BWP, including:

Step 401: Detect the signal quality on the first BWP.

Wherein, detecting the signal quality on the first BWP includes: detecting the beam signal quality on the first BWP, and/or detecting the cell signal quality on the first BWP.

In practical applications, the beam signal quality can be characterized by the SSB and/or CSI-RS signal quality on the first BWP, such as beam reference signal received power (RSRP, Reference Signal Receiving Power), reference signal received quality (RSRQ, Reference Signal Receiving Quality) or Signal to Interference plus Noise Ratio (SINR, Signal to Interference plus Noise Ratio).

In practical application, the signal quality of the cell may be RSRP, RSRQ, or SINR of the cell.

Step 402: When the detected signal quality satisfies at least one of the following conditions, it is determined that the random access process is not performed on the first BWP:

The detected SSB and/or CSI-RS signal quality on the first BWP is greater than a first threshold;

The detected signal quality of the cell corresponding to the first BWP is greater than the second threshold.

Wherein, when the detected signal satisfies at least one of the above conditions, it means that the current location of the terminal at this time is already a non-coverage hole area. Therefore, the terminal can perform a random access procedure on the second BWP.

Here, in practical application, the network device may configure the first threshold and the second threshold for the terminal.

Based on this, in one embodiment, the method further includes:

The corresponding threshold sent by the network device on the first BWP is received.

Specifically, the corresponding threshold may include a first threshold and/or a second threshold.

It can be seen from the above description that the first threshold is used to judge the signal quality of the SSB and/or CSI-RS on the first BWP, and the second threshold is used to judge the signal quality of the cell on the first BWP. 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.

Among them, on the network device side, the threshold can be determined by the following methods:

First, coverage holes on the second BWP can be determined. In practical applications, a coverage hole on the second BWP can be determined by using relevant software for channel and coverage estimation. Generally, an area with a signal reception quality less than -80 dBm is determined as a coverage hole. After the coverage hole is determined, the actual signal values at different positions within the coverage hole are determined. Finally, a corresponding threshold is determined according to the determined highest signal value and lowest signal value. Specifically, the threshold may be determined from the beam and/or cell perspective. When the threshold is determined from the perspective of the beam, the signal value (such as RSRP, RSRQ, or SINR, etc.) of the beam covering each position of the hole is detected, and the highest signal value of the signal value of the beam is determined from the detected positions, and the detection Cover the signal values of the beams at each position of the non-covering hole around the hole, and determine the lowest signal value of the signal value of the beam, so as to determine the beam quality judgment threshold covering the hole according to the highest signal value and the lowest signal value, that is, the first threshold. When the threshold is determined from the perspective of the cell, the signal value (such as RSRP, RSRQ, or SINR, etc.) of the cell covering each location of the hole is detected, and the highest signal value of the signal value of the cell is determined from the detected locations, and the detection Cover the signal values of the cells around the non-coverage holes, and determine the lowest signal value of the signal values of the cells, so as to determine the quality judgment threshold of the cells covering the hole according to the highest signal value and the lowest signal value, that is, the second threshold.

In an embodiment, the network device sends the corresponding threshold on the first BWP, and the terminal receives the corresponding threshold sent by the network device on the first BWP. In practical application, the network device can broadcast the corresponding threshold through a broadcast message on the first BWP, and the terminal is in an idle state, that is, in a state where the terminal has not established an RRC connection with the network device, and receives the broadcast message of the network device on the first BWP, The corresponding threshold is obtained from it.

In step 302, the terminal receives the first information on the first BWP.

Here, the first information includes one of the following information:

Frequency point information of the second BWP.

The terminal may calculate the frequency point of the second BWP based on the frequency point of the first BWP according to the frequency point difference information between the second BWP and the first BWP.

Here, in practical application, the frequency point difference information may be a frequency point difference value between the second BWP and the first BWP.

Correspondingly, the frequency point information of the second BWP may also be the frequency point value of the second BWP.

In practical application, the network device may broadcast the first information, or may send the first information to the terminal through RRC signaling.

Based on this, in an embodiment, when the first information is received on the first BWP, the method includes at least one of the following:

receiving the first information broadcast by the network device through a broadcast message;

The first information sent by the network device through RRC signaling is received.

Among them, in practical applications, the terminal in the idle state can receive the broadcast message of the network device on the first BWP, and obtain the first information from it; the network device can also send the first information to the terminal through RRC signaling, such as RRC Connection reconfiguration messages, etc.

In practical applications, after receiving the first information, the terminal uses the first information to determine the frequency of the second BWP, so that based on the frequency of the second BWP, the terminal converts (which can also be understood as transferring) to the second BWP for randomization. access process.

Correspondingly, an embodiment of the present invention also provides a random access configuration method, applied to a network device, including:

First information is sent on the first BWP; the first information is used for the terminal to determine the frequency point of the second BWP, so that in the case of not performing the random access procedure on the first BWP, the second A random access procedure is performed on the BWP.

Wherein, the network device repeatedly broadcasts the second information on the first BWP; the second information is the SSB covering the hole direction of the network device. By repeatedly broadcasting the SSB covering the hole direction on the first BWP by the network device, the signal quality covering the hole direction can be improved.

Here, the first information sent by the network device on the first BWP includes one of the following information:

Frequency point difference information of the second BWP and the first BWP;

Frequency point information of the second BWP.

The network device may send frequency difference information between the second BWP and the first BWP on the first BWP, so that the terminal calculates the frequency of the second BWP based on the frequency of the first BWP. Here, the frequency difference The information can be the frequency difference value between the second BWP and the first BWP; the network device can also send the frequency value of the second BWP on the first BWP, and the terminal directly receives the frequency of the second BWP on the first BWP. value.

In an embodiment, when the first information is sent on the first BWP, the method includes at least one of the following:

The first information is sent through RRC signaling.

In practical applications, the network device can broadcast the first information through the broadcast message of the first BWP, and the terminal in the idle state can receive the broadcast message of the network device on the first BWP, and obtain the first information from it; when the terminal communicates with the network When the device is in the connected state, the network device may also send the first information to the terminal through RRC signaling.

In practical applications, after receiving the first information, the terminal uses the first information to determine the frequency point of the second BWP, so that based on the frequency point of the second BWP, it is converted to the second BWP by frequency hopping for randomization. access process.

In one embodiment, the method may further include:

Send a corresponding threshold on the first BWP, where the corresponding threshold includes at least one of the following:

a first threshold; the first threshold is used for the terminal to determine whether the detected SSB and/or CSI-RS signal quality on the first BWP is greater than the first threshold;

a second threshold; the second threshold is used for the terminal to determine whether the detected signal quality of the cell corresponding to the first BWP is greater than the second threshold.

The network device sends the corresponding threshold on the first BWP, and the terminal receives the corresponding threshold sent by the network device on the first BWP. Further, the network device broadcasts the corresponding threshold through a broadcast message on the first BWP, and the terminal receives the broadcast message of the network device on the first BWP in an idle state to obtain 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.

An embodiment of the present invention provides a random access method, as shown in FIG. 5 , the method includes:

Step 501: The network device repeatedly broadcasts the second information on the first BWP, and sends the first information on the first BWP.

Wherein, the second information is the SSB of the network device covering the direction of the hole.

Step 502: the terminal determines the frequency point of the second BWP by using the first information received on the first BWP without performing a random access procedure on the first BWP;

Step 503: The terminal performs a random access procedure on the second BWP.

It should be noted that the specific processing procedures of the network device and the terminal have been described in detail above, and will not be repeated here.

In this embodiment of the present invention, the network device repeatedly broadcasts the second information on the first BWP, where the second information is the SSB in the first direction, and sends the first information on the first BWP, and the terminal does not perform the first information on the first BWP. In the case of the random access procedure, use the first information received on the first BWP to determine the frequency of the second BWP, and perform the random access procedure on the second BWP, and determine not to perform random access on the BWP that broadcasts the second information. After the access process, since the terminal knows the first information and determines the frequency of the second BWP, the random access process can be performed on the frequency of the second BWP. In this way, it can be avoided that random access should normally be performed on the original BWP. When detecting a new BWP broadcasting an SSB in a certain direction, the terminal in the access process performs a random access process on the new BWP, thereby further avoiding unreasonable consumption of access resources of the new BWP.

The present invention will be further described in detail below in conjunction with application examples.

After entering the process, step 603 is executed.
