An optional process flow 200 of a method for configuring cell access resources under strong interference conditions in an embodiment of the present application is shown in fig. 2, where the process flow 200 includes the following steps:

in step 201, the time-frequency location of the current channel of the cell subject to strong interference is determined.

In the embodiment of the application, the channels can comprise an uplink channel and a downlink channel. Correspondingly, the current channel of the cell being subjected to strong interference may include the uplink channel being subjected to strong interference and/or the downlink channel being subjected to strong interference.

Step 202, reconfiguring cell channel resources avoiding the time-frequency position where the current channel is subject to strong interference.

In some embodiments, the network device may avoid the determined time-frequency locations subject to strong interference when reconfiguring cell channel resources.

In some embodiments, the network device may reconfigure the cell channel resources corresponding to the uplink channel being subjected to strong interference and/or the downlink channel being subjected to strong interference, corresponding to avoiding the time-frequency location corresponding to the uplink channel and/or the time-frequency location corresponding to the downlink channel.

In some embodiments, among the available time-frequency location resources in the current communication system, a time-frequency resource that is not interfered may be determined in addition to the time-frequency location that has been determined to be strongly interfered.

In some embodiments, an alternative process 300 of the method for configuring cell access resources under strong interference conditions in the embodiments of the present application is shown in fig. 3, where the process 300 may include the following steps:

in step 301, a frequency domain RSRP (Reference Signal Received Power ) value corresponding to a current uplink channel of the cell is detected.

Here, detecting the frequency domain RSRP value corresponding to the current uplink channel of the cell may include: the network device detects the RSRP value of the current uplink RACH (Random Access Channel ).

In some embodiments, the base station is required on an operation and maintenance station of the network device to measure the signal strength of the PRACH (Physical Random Access Channel ) and give a signal strength threshold RSRPx (RSRP Max ) for the PRACH to be interfered with.

Step 302, determining that the current uplink channel is subjected to strong interference in response to detecting that the RSRP value corresponding to the current uplink channel exceeds a preset uplink signal strength threshold value.

In some embodiments, the preset uplink signal strength threshold may include RSRPx, which may be preset according to configuration requirements of the network device.

In some embodiments, the base station detects that the RSRP value of the RACH uplink frequency domain has exceeded the RSRPx required by the operation and maintenance station, so that it can be determined that there is strong interference in the PRACH resource region;

In step 303, it is determined that the time-frequency location of the current channel subject to strong interference includes the time-frequency location corresponding to the current uplink channel.

It will be appreciated that steps 301 to 303 correspond to an alternative implementation of step 201 in the embodiment of fig. 2, where the time-frequency location of the current channel is subject to strong interference may be determined by determining the time-frequency location corresponding to the current uplink channel.

Step 304, the RACH resource is reconfigured avoiding the time-frequency position corresponding to the current uplink channel.

In some embodiments, the network device reconfiguring RACH resources may include a change to PRACH resources, in particular: and selecting time-frequency position which can meet the length of RA preamble (Random Access Preamble ) from the time-frequency resources which are not interfered, or correlating the time-frequency position of the network equipment for transmitting RAR message to obtain parameter information, and putting the selected time-frequency position information into a SIB1 (System Information Block, system message block 1) message block to be transmitted in the next SIB1 transmission period.

In some embodiments, an alternative process flow 400 of the method for configuring cell access resources under strong interference conditions in the embodiments of the present application is shown in fig. 4, where the process flow 400 may include the following steps:

In step 401, in response to receiving the downlink interference report information, it is determined that the time-frequency location of the current channel subject to strong interference includes the time-frequency location corresponding to the current downlink channel of the cell.

In the embodiment of the present application, the time-frequency location corresponding to the current downlink channel of the cell may include a time-frequency location used by RAR (Random Access Respond, random access response) information.

In the embodiment of the present application, the downlink interference report information may include a specific preamble, where the specific preamble may be preset. The specific preamble is used for the network device to determine that the terminal device receives the RAR information of the network device and is subjected to strong interference after receiving the specific preamble.

In some embodiments, receiving the downlink interference report information may include: the network device receives a specific preamble at the time-frequency location of the current PRACH resource.

Step 402, the downlink channel resource is reconfigured avoiding the time-frequency position corresponding to the current downlink channel.

In some embodiments, reconfiguring the downlink channel resources may include reconfiguring a time-frequency location at which the RAR information is transmitted.

In some embodiments, the network device receives a specific preamble, determines that there is strong interference in the time-frequency location where the RAR information is currently sent, and stops sending the RAR information. The network device searches for a time-frequency position suitable for transmitting the RAR information in the time-frequency resource which is not interfered, and transmits the RAR information to the terminal device which has transmitted the RA (Random Access) request on the time-frequency position.

It will be appreciated that, in an alternative implementation manner corresponding to step 201 and step 202, step 401 and step 402 may determine, by receiving the downlink interference report information, that the time-frequency location where the current channel is subject to strong interference includes the time-frequency location corresponding to the current downlink channel of the cell, and avoid reconfiguring the downlink channel resources at the time-frequency location corresponding to the current downlink channel.

In some embodiments, an alternative process flow 500 of the method for configuring cell access resources under strong interference conditions in the embodiments of the present application is shown in fig. 5, where the process flow 500 may include the following steps:

in step 501, in response to receiving the downlink interference report information, and in response to not receiving the contention information corresponding to the downlink interference report information within a preset period of time, it is determined that the time-frequency position of the current channel subject to strong interference includes the time-frequency position corresponding to the current downlink channel of the cell and the time-frequency position corresponding to the current uplink channel.

In some embodiments, the network device receives a specific preamble at the time-frequency location of the current PRACH resource, and the network device does not receive any contention preamble at the PRACH resource location for a period of time, and the network device may determine that the current PRACH resource is strongly interfered, and that the time-frequency location where the RAR information is currently transmitted is strongly interfered. The network device therefore needs to change the new RAR resources and also the resources of the PRACH.

Step 502, the time-frequency positions corresponding to the current uplink channel and the current downlink channel are avoided to reconfigure the uplink channel and the downlink channel resources.

In some embodiments, the step 502 may specifically include reconfiguring uplink channel resources while avoiding the time-frequency location corresponding to the current uplink channel and reconfiguring downlink channel resources while avoiding the time-frequency location corresponding to the current downlink channel, and the specific configuration method is described in the steps 304 and 402, which are not repeated herein.

It will be appreciated that, in an alternative implementation manner corresponding to steps 201 and 202, step 501 and step 502 may determine that the time-frequency location where the current channel is subject to strong interference includes the time-frequency locations corresponding to the current uplink channel and the downlink channel of the cell by receiving the downlink interference report information and not receiving the contention information corresponding to the downlink interference report information within the preset duration, so as to avoid the time-frequency locations corresponding to the current uplink channel and the downlink channel from reconfiguring the channel resources.

In some embodiments, a method for configuring a cell access resource under a strong interference condition according to an embodiment of the present application may further include the following steps, as shown in fig. 6:

In step 601, the network device sends offline measurement information to the terminal device in the cell in a connected state through the current channel.

In some embodiments, the terminal device and the network device establish a connection, and the terminal device is in a connected state. Here, the terminal device being in the connected state may include entering an RRC (Radio Resource Control ) -connected state, the terminal device being required to leave the connected state for some reason, entering a non-connected state, for example: reverting to the RRC-idle or RRC-inactive state. In the embodiment of the application, the offline measurement information may comprise a RACH-measurement message module. The network device needs to carry an RACH-measurement message block in the RRC message sent to the terminal device, where the RACH-measurement message block is used to enable the terminal device to measure the downlink channel energy of the access resource of the cell in a non-connected state.

Here, the RRC message may include an RRC message that the network device notifies the terminal device of RRC release, RRC reject, RRC Reconfiguration reconfiguration, RRC Reestablishment reestablishment, and the like.

The RACH-measurement message block contains the following contents: and reporting the resource block set possibly used by the RAR message, the energy value of the resource block used by each subcarrier or each RB or the RAR message, and the measurement threshold value with high RAR failure probability. Wherein, the RAR message uses resource block set as RAR message, and there should be multiple resource blocks, such as one RB,2 RBs, specific subcarrier number of each RB, etc., according to the length of message content; the measurement threshold with high RAR failure probability is an RSRP value for a resource block of the RAR message, which means that when the RSRP value is higher, the failure probability of the terminal device to receive the RAR message is higher than the network allowable range.

The reporting mode comprises two modes: firstly, reporting at any time, and reporting once the measured RSRP value is found to be larger than a threshold value with high RAR failure probability; and secondly, waiting for a period of time, and reporting when the terminal equipment enters a connection state.

Step 602, after the terminal device leaves the connection state in the cell, detecting an RSRP value corresponding to the current downlink channel according to the offline measurement information.

In step 603, the terminal device reports the downlink interference report information in response to detecting that the RSRP value corresponding to the downlink channel exceeds the preset downlink signal strength threshold value.

Here, the preset downlink signal strength threshold may include a measurement threshold with a high reporting RAR failure probability included in the RACH-measurement message block.

It can be appreciated that in the embodiment of the present application, a method of reporting at any time is adopted. In some embodiments, the RACH measurement content is reserved after the terminal device leaves the RRC-connected state; starting to measure the resource blocks used by the RAR message at fixed time according to the indication of the RACH measurement message; and if the measured RSRP is found to be higher than the threshold value with high RAR failure probability, reporting according to a preset reporting mode.

In some embodiments, reporting the downlink interference report information may include: and sending the downlink interference report information to the network equipment at preset power.

Because the terminal equipment is in a non-connection state, the terminal equipment cannot report a specific message data packet, but can send a specific preamble, and the sending power of the specific preamble is sent according to the maximum power which can be used when the terminal equipment sends the preamble, so that the network equipment can receive the specific preamble under the condition that strong interference exists outside. In the embodiment of the application, the time-frequency position of the specific preamble is the same as the preamble time-frequency position in the RA process.

In step 604, the network device determines, in response to receiving the downlink interference report information, that the time-frequency location of the current channel subject to strong interference includes a time-frequency location corresponding to the current downlink channel of the cell.

In step 605, the network device reconfigures the downlink channel resources avoiding the time-frequency location corresponding to the current downlink channel.

Here, step 604 and step 605 correspond to step 401 and step 402 in the embodiment of fig. 4, and specific configuration methods have been described in step 401 and step 402, which are not described herein.

In some embodiments, the network device reconfiguring RACH resources may include a change to PRACH resources, in particular: and selecting a time-frequency position which can meet the RA preamble length from the time-frequency resources which are not interfered, putting the selected time-frequency position information into an SIB1 message block and/or correlating the time-frequency position of the RAR message sent by the network equipment to obtain parameter information, and sending the parameter information in the next SIB1 sending period.

After receiving the new SIB1 message content, the terminal device sends a preamble on the new PRACH resource to overcome the influence of strong interference.

In some embodiments, another alternative interaction flow of the method for configuring cell access resources under the strong interference condition in the embodiment of the present application, as shown in fig. 7, may include the following steps:

in step 701, the network device sends online measurement information to at least two terminal devices in a cell in a connection state through a current channel.

In some embodiments, in order to determine whether the RACH resource is strongly interfered, the network device may randomly select at least two terminal devices in an RRC-connected state with the network device, send online measurement information to the terminal devices, and ask the terminal devices to immediately measure and report the signal strength of the PRACH downlink resource indicated in the online measurement information.
