Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a method, apparatus, related device, and storage medium for processing access scheduling resources. Background Art

[0002] In the prior art and solutions, when the network load is not high, there will be no situation of insufficient resources of the Control-Resource Set (CORESET0) or scheduling congestion during user access. However, in a large-capacity scenario with a high network load, the number of burst access users surges, the uplink interference of the cell is severe, the aggregation level of the Physical Downlink Control Channel (PDCCH) increases, and a large number of retransmission and reconstruction processes occur. On the one hand, signaling such as the initial retransmission of MSG3 / MSG5, Bandwidth Part (BWP) switching, and all scheduling during the Radio Resource Control (RRC) reconfiguration ambiguity period also consumes CORESET0 resources, resulting in the phenomenon that users cannot access and the Control Channel Element (CCE) of the control resource is congested, seriously affecting the network radio connection rate and network indicators. On the other hand, although the protocol stipulates that MSG4 can indicate dedicated PDCCH resources, the User Equipment (UE) does not measure any measurement and evaluation channels, which cannot ensure that the UE correctly receives information and initiates a handover, thus affecting UE access.

[0073] The present application will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0074] New Radio (NR) users need to use PDCCH resources to be responsible for the transmission of various key control information at the physical layer. The base station needs to send downlink control information (DCI) to the UE through the PDCCH to instruct the UE to perform corresponding uplink (UL) and downlink (DL) procedures. In NR, the network side will configure multiple CORESETs and search spaces in the BWP, and the time-frequency resources are determined by pairing the two. Among them, the CORESET concept corresponds to the physical resource configuration of the PDCCH, and the CORESET mainly corresponds to the frequency-domain resources. During the NR user access process, a special CORESET, called CORESET0, is configured for RMSI (SIB1). The time-frequency domain resource location of CORESET 0 is obtained from pdcch-ConfigSIB1 in the Management Information Base (MIB). This resource cannot change arbitrarily with the bandwidth size, and its resource has a fixed pattern, with a maximum of 72 RBs (16 CCEs). In the current access process, before the UE completes random access, the CORESET0 resources are consumed to carry DCI information. At the same time, the processes related to UE access also consume CORESET0 resources, such as Paging, SIB, RAR, Msg4, MSG3 / MSG5 initial and retransmission, BWP switching, and all scheduling during the RRC reconfiguration ambiguity period.

[0075] In the existing access scheme, the DCI invocations of signaling processes such as msg1-msg5, RRC Setup, UE Capability, Security, and RRC Reconfiguration are all in CORESET 0 of the initial BWP, resulting in relatively high resource consumption. It can be combined with Figure 1 for understanding. Figure 1 It is a schematic diagram of DCI invocation for signaling processes.

[0076] In the prior art and solutions, when the network load is low, there will be no situation of insufficient CORESET0 resources or scheduling congestion during user access. However, in a large-capacity scenario with a high network load, the number of suddenly accessing users surges, the uplink interference of the cell is severe, the PDCCH aggregation level increases, and there are a large number of retransmission and reconstruction processes. On the one hand, signaling such as the initial retransmission of MSG3 / MSG5, BWP switching, and all scheduling during the RRC reconfiguration ambiguity period also consumes CORESET0 resources, resulting in the phenomenon that users cannot access and the control resource CCE is congested, seriously affecting the network radio connection rate and network indicators. On the other hand, although the protocol stipulates that MSG4 can indicate dedicated PDCCH resources, the UE does not measure any measurement and evaluation channels, so it cannot ensure that the UE correctly receives information and initiates a handover, thereby affecting UE access.

[0077] Based on this, in various embodiments of the present application, it is determined whether the terminal meets the BWP switching condition through the channel environment information and access information corresponding to the terminal; when the terminal meets the BWP switching condition, a first message carrying the resource information of the dedicated BWP is sent to the terminal, so that the terminal accesses the dedicated BWP, reducing the consumption of the common control resource set, thereby ensuring UE access and improving the network radio connection rate index.

[0078] An embodiment of the present application provides a method for processing access scheduling resources, which is applied to a network device. Figure 2 It is a schematic flowchart of a method for processing access scheduling resources of the present application; as Figure 2 shown, the method includes:

[0079] Step 201: Determine whether the terminal meets the switching condition of the partial bandwidth BWP based on the channel environment information and access information corresponding to the terminal;

[0080] Step 202: When the terminal meets the BWP switching condition, send a first message to the terminal; the first message carries the resource information of the dedicated BWP; the resource information is used for the terminal to access the dedicated BWP.

[0081] In this embodiment, the network device can be determined according to the actual situation and is not limited herein. As an example, the network device can be a base station.

[0082] In step 201, the terminal can be determined according to the actual situation and is not limited herein. As an example, the terminal can be a user terminal, denoted as UE.

[0083] Determine whether the terminal meets the switching conditions of the partial bandwidth BWP based on the channel environment information and access information corresponding to the terminal; wherein, the switching conditions of the BWP can be determined according to the actual situation and are not limited herein. As an example, the switching conditions of the BWP can include a first condition and / or a second condition; the first condition represents a first threshold range corresponding to a first TA parameter; the second condition represents a second threshold range corresponding to the first channel environment parameter; both the first condition and the second condition can be determined according to the actual situation and are not limited herein. As an example, the first condition can be to parse the random access MSG2 and determine that the TA value ∈ [0, N]; the second condition can be to parse the channel environment of MSG3-DMRS and determine that the channel condition ≥ channel threshold a. The determining whether the terminal meets the switching conditions of the partial bandwidth BWP based on the channel environment information and access information corresponding to the terminal can include determining whether the first TA parameter meets the first threshold range to obtain a first result; determining whether the first channel environment parameter meets the second threshold range to obtain a second result; and determining whether the terminal meets the switching conditions of the BWP based on the first result and / or the second result. Both the channel environment information and the access information can be determined according to the actual situation and are not limited herein. As an example, the channel environment information can include a first channel environment parameter; the access information can include a first time advance TA parameter.

[0084] In step 202, whether the terminal meets the switching conditions of the BWP can be determined according to the actual situation and is not limited herein. As an example, the terminal meeting the switching conditions of the BWP can be understood as the UE meeting the conditions to initiate an initial BWP switch from msg4 to the dedicated BWP. Send a first message to the terminal; the first message carries the resource information of the dedicated BWP; the resource information for the terminal to access the dedicated BWP can be understood as using the dedicated PDCCH resource in the subsequent access process, reducing the consumption of the common PDCCH CORESET0, thereby ensuring the access of the UE and improving the network radio connection rate index.

[0085] In this embodiment, an optimized method is used to determine whether the UE meets the conditions to initiate an initial BWP switch from msg4 to the dedicated BWP, so that the subsequent access process uses the dedicated PDCCH resource, reduces the consumption of the common PDCCH CORESET0, thereby ensuring the access of the UE and improving the network radio connection rate index.

[0086] In an embodiment of the present application, it is determined whether a terminal meets the BWP handover condition based on the channel environment information and access information corresponding to the terminal; when the terminal meets the BWP handover condition, a first message carrying resource information of a dedicated BWP is sent to the terminal, so that the terminal accesses the dedicated BWP, reducing the consumption of the common control resource set, thereby ensuring UE access and improving the network radio connection rate index.

[0087] In one embodiment, the channel environment information includes a first channel environment parameter, and the method further includes:

[0088] Receiving a first message of RA sent by the terminal;

[0089] Parsing the first message to obtain power control information corresponding to the terminal;

[0090] Determining the first channel environment parameter based on the power control information.

[0091] In this embodiment, the channel environment information includes a first channel environment parameter; the first channel environment parameter can be determined according to actual situations and is not limited herein. As an example, the first channel environment parameter may include a channel threshold.

[0092] For easy understanding, an example is given here. Suppose that a large number of random access, reconfiguration, and reconstruction processes that consume CORESET 0 resources occur within the cell coverage area, and at this time, users (number X) initiate random access messages in the same cell. That is, it can be understood as receiving the first message of RA sent by the terminal; among them, the first message can be determined according to actual situations and is not limited herein. As an example, the first message may be UE MSG1 - Preamble and MsgA - preamble.

[0093] Parsing the first message to obtain power control information corresponding to the terminal; among them, the power control information can be determined according to actual situations and is not limited herein. As an example, the power control information may be the transmit power.

[0094] Determining the first channel environment parameter based on the power control information;

[0095] In practical applications, suppose that a large number of random access, reconfiguration, and reconstruction processes that consume CORESET 0 resources occur within the cell coverage area, and at this time, users (number X) initiate random access in the same cell. Parse the UE power control information (such as transmit power) in UE MSG1 - Preamble and MsgA - preamble, and the TA value of the MSG2 - RAR and MsgB - RAR messages sent by the base station.

[0096] In one embodiment, the access information includes a first Timing Advance (TA) parameter; the method further includes:

[0097] Sending a second message of the Random Access Response (RAR) to the terminal; the second message is for the terminal to perform parsing to obtain the first TA parameter.

[0098] In this embodiment, the access information includes a first Timing Advance (TA) parameter; the TA parameter can be determined according to the actual situation and is not limited herein. As an example, the TA parameter may include a TA value.

[0099] Sending a second message of the RAR to the terminal; the second message can be determined according to the actual situation and is not limited herein. As an example, the second message may include MSG2-RAR and MsgB-RAR messages.

[0100] In practical applications, the TA values of the MSG2-RAR and MsgB-RAR messages sent by the base station.

[0101] In one embodiment, the switching condition of the Bandwidth Part (BWP) includes a first condition and / or a second condition; the first condition represents a first threshold range corresponding to the first TA parameter; the second condition represents a second threshold range corresponding to the first channel environment parameter; determining whether the terminal meets the switching condition of the partial bandwidth BWP based on the channel environment information and access information corresponding to the terminal includes:

[0102] Judging whether the first TA parameter meets the first threshold range to obtain a first result;

[0103] Judging whether the first channel environment parameter meets the second threshold range to obtain a second result;

[0104] Determining whether the terminal meets the switching condition of the BWP based on the first result and / or the second result.

[0105] In this embodiment, the switching condition of the BWP including the first condition and / or the second condition can be understood as the switching condition of the BWP including the first condition; the switching condition of the BWP including the second condition; the switching condition of the BWP including the first condition and the second condition. Both the first condition and the second condition can be determined according to the actual situation and are not limited herein. As an example, the first condition may be parsing the random access MSG2 and judging that the TA value ∈ [0, N]; the second condition may be parsing the channel environment of MSG3-DMRS and judging that the channel condition ≥ channel threshold a.

[0106] The first condition characterizes a first threshold range corresponding to the first TA parameter; wherein, the first threshold range can be determined according to actual situations and is not limited herein. As an example, the first threshold range can be denoted as [0, N].

[0107] The second condition characterizes a second threshold range corresponding to the first channel environment parameter; wherein, the second threshold range can be determined according to actual situations and is not limited herein. As an example, the second threshold range can be understood as being greater than or equal to a.

[0108] Determining whether the first TA parameter meets the first threshold range and obtaining a first result can be understood as determining whether the first TA parameter meets the first threshold range and obtaining a first result that the first TA parameter meets the first threshold range or the first TA parameter does not meet the first threshold range.

[0109] Determining whether the first channel environment parameter meets the second threshold range and obtaining a second result can be understood as determining whether the first channel environment parameter meets the second threshold range and obtaining a second result that the first channel environment parameter meets the second threshold range or the first channel environment parameter does not meet the second threshold range.

[0110] Determining whether the terminal meets the BWP switching condition based on the first result and / or the second result can be understood as determining whether the terminal meets the BWP switching condition based on the first result that the first TA parameter meets the first threshold range or the first TA parameter does not meet the first threshold range and / or the second result that the first channel environment parameter meets the second threshold range or the first channel environment parameter does not meet the second threshold range. As an example, determining whether the terminal meets the BWP switching condition based on the first result and / or the second result can include determining that the terminal meets the BWP switching condition when the first result characterizes that the first TA parameter meets the first threshold range and / or the second result characterizes that the first channel environment parameter meets the second threshold range; and determining that the terminal does not meet the BWP switching condition when the first result characterizes that the first TA parameter does not meet the first threshold range and the second result characterizes that the first channel environment parameter does not meet the second threshold range.

[0111] In one embodiment, determining whether the terminal meets the BWP switching condition based on the first result and / or the second result includes:

[0112] When the first result indicates that the first TA parameter meets the first threshold range and / or the second result indicates that the first channel environment parameter meets the second threshold range, it is determined that the terminal meets the handover condition of the BWP;

[0113] When the first result indicates that the first TA parameter does not meet the first threshold range and the second result indicates that the first channel environment parameter does not meet the second threshold range, it is determined that the terminal does not meet the handover condition of the BWP.

[0114] It should be noted that when the first result indicates that the first TA parameter meets the first threshold range, it can be understood that the first result indicates that the TA value ∈ [0, N]. When the second result indicates that the first channel environment parameter meets the second threshold range, it can be understood that the channel condition ≥ the channel threshold a.

[0115] In practical applications, the handover conditions of the BWP may include: ① Analyze the random access MSG2 and determine whether the TA value ∈ [0, N]; ② Analyze the channel environment of MSG3 - DMRS and determine whether the channel condition ≥ the channel threshold a.

[0116] In an embodiment, when the first result indicates that the first TA parameter meets the first threshold range and the second result indicates that the first channel environment parameter does not meet the second threshold range, the method further includes:

[0117] Send the first information to the first terminal whose first TA parameter meets the first threshold range; the first information carries the resource information of the dedicated BWP; the resource information is used for the first terminal to access the dedicated BWP.

[0118] It should be noted that the handover conditions of the BWP may include: ① Analyze the random access MSG2 and determine whether the TA value ∈ [0, N]; ② Analyze the channel environment of MSG3 - DMRS and determine whether the channel condition ≥ the channel threshold a.

[0119] When the first result indicates that the first TA parameter meets the first threshold range and the second result indicates that the first channel environment parameter does not meet the second threshold range, it can be understood that UEs that only meet ① can access normally, and UEs that only meet ② cannot access normally, indicating that the channel threshold is set too high. Then, based on the channel prediction method, the probability limit threshold is lowered and the channel threshold is reduced.

[0120] In an embodiment, the method further includes:

[0121] Receive the third message sent by the first terminal;

[0122] Perform channel environment pre - evaluation on the third message using TDD to obtain the second channel environment parameters corresponding to the first terminal;

[0123] Obtain the power control parameters and physical layer parameters of the first terminal;

[0124] Determine the first correction factor for the second threshold range based on the second channel environment parameters, the power control parameters, and the physical layer parameters;

[0125] Adjust the second threshold range based on the first correction factor so that the first channel environment parameters meet the adjusted second threshold range.

[0126] It should be noted that the third message can be determined according to the actual situation and is not limited here. As an example, the third message may include MSG3 and / or MsgA; MsgA may include the content of MSG3.

[0127] Perform channel environment pre - evaluation on the third message using TDD to obtain the second channel environment parameters corresponding to the first terminal; wherein, the second channel environment parameters can be determined according to the actual situation and are not limited here. As an example, the second channel environment parameters may include channel sounding reference signal (Sounding Reference Signal, SRS), channel state information (Channel state information, CSI).

[0128] Obtain the power control parameters and physical layer parameters of the first terminal; wherein, both the power control parameters and the physical layer parameters can be determined according to the actual situation and are not limited here. As an example, the power control parameters may include UE open - loop power control parameters; the physical layer parameters may include reference signal receiving power (Reference Signal Receiving Power, RSRP), physical random access channel (Physical Random Access Channel, PRACH).

[0129] Determine the first correction factor for the second threshold range based on the second channel environment parameters, the power control parameters, and the physical layer parameters; wherein, the first correction factor can be determined according to the actual situation and is not limited here. As an example, the first correction factor may be denoted as Φ.

[0130] Adjust the second threshold range based on the first correction factor so that the first channel environment parameter meets the adjusted second threshold range. As an example, the channel condition is channel threshold a; the FDD frequency band is corrected by Φ, the uplink channel environment is obtained by decoding MSG3, and the downlink channel condition decision threshold is a + Φ.

[0131] In practical applications, the base station decodes the MSG3 and MsgA (including the content of MSG3) messages sent by the UE. For TDD, the uplink channel environment can be utilized by the channel reciprocity through MSG3, and the downlink channel environment is pre-evaluated based on the uplink channel environment parsed by MSG3-DMRS; for FDD, although the uplink and downlink have different carrier frequencies, in one channel, the uplink and downlink channels have the same physical propagation path (fading coefficient, angle of arrival / departure, time delay). The dB difference between the uplink and downlink channels of FDD is pre-evaluated through the environmental propagation model, assuming Φ. The current channel environment is obtained through MSG3-DMRS. Compared with the measurement report values of SRS, CSI, etc., the accuracy is insufficient. Combining the UE open-loop power control parameters and the high-layer parameters of the base station such as HigherlayerfilteredRSRP and PRACH, a pre-evaluation factor is introduced. The UE open-loop power control parameters and the high-layer parameters of the base station such as HigherlayerfilteredRSRP and PRACH reflect the environment of the PRACH channel. The channel and TA data graph of PRACH and the channel and TA data graph solved by MSG3-DMRS can be judged based on the empirical values within a period of time. If the difference between the standard deviations of the two is greater than the set difference, it indicates that the environmental differences between the two are large. Then, a CDF graph is formed with the channel data of MSG3-DMRS (relatively more accurate). When the probability is less than the set threshold, the corresponding channel condition is channel threshold a; if the difference between the standard deviations of the two is less than the set difference, it indicates that the current environmental differences between the two are small. Then, an expectation correction and data averaging process are performed to form a CDF graph. When the probability is less than the set threshold, the corresponding channel condition is channel threshold a; the FDD frequency band is corrected by Φ, the uplink channel environment is obtained by decoding MSG3, and the downlink channel condition decision threshold is a + Φ.

[0132] In one embodiment, when the first result indicates that the first TA parameter does not meet the first threshold range and the second result indicates that the first channel environment parameter meets the second threshold range, the method further includes:

[0133] Send the first information to a second terminal whose first channel environment parameter meets the second threshold range; the first information carries the resource information of the dedicated BWP; the resource information is used for the second terminal to access the dedicated BWP.

[0134] It should be noted that the handover conditions of the BWP may include: ① Analyze the random access MSG2 and determine that the TA value ∈ [0, N]; ② Analyze the channel environment of MSG3-DMRS and determine that the channel condition ≥ channel threshold a.

[0135] It can be understood that the first result indicates that the first TA parameter does not meet the first threshold range, and the second result indicates that the first channel environment parameter meets the second threshold range. That is, only the UE that satisfies ② can access normally, and the UE that only satisfies ① cannot access normally, indicating that the current TA range threshold setting is too small. Then, based on the CDF distribution of TA, increase the probability setting threshold and increase the TA condition decision range N.

[0136] In this embodiment, for the UE that meets the conditions, when the base station sends msg4 or MsgB, it carries dedicated BWP resource information. After the UE receives it, it performs BWP handover and uses dedicated PDCCH resources for scheduling; for the UE that meets some conditions, it is corrected according to the access situation: for the UE that only satisfies ②, give priority to executing the dedicated BWP configuration when sending Msg4.

[0137] In an embodiment, the access information corresponding to the second terminal includes a second TA parameter; the method further includes:

[0138] Obtain the access times of the second terminal within the first threshold range and the distribution range of the second TA parameter;

[0139] Generate a distribution function CDF based on the access times and the distribution range;

[0140] Determine a second correction factor for the first threshold range according to the CDF;

[0141] Adjust the first threshold range based on the second correction factor so that the second TA parameter meets the adjusted first threshold range.

[0142] In this embodiment, the second TA parameter can be determined according to the actual situation and is not limited herein. As an example, the second TA parameter can be a TA value; the TA value can include RAR and MAC CE.

[0143] Obtain the access times of the second terminal within the first threshold range; wherein, the first threshold range can be determined according to the actual situation and is not limited herein. As an example, the first threshold range can be denoted as [0, N]. In practical applications, obtaining the access times of the second terminal within the first threshold range can be obtaining the access times of the TA value within the interval range N when the user performs random access.

[0144] The distribution range for obtaining the second TA parameter may be to obtain the distribution of TA values (including RAR and MAC CE).

[0145] In practical applications, a CDF graph is generated based on "the number of access times when the TA value is within the interval range N during user random access" and "the distribution of TA values (including RAR and MAC CE)". When the probability is less than the set threshold, the corresponding TA value is the decision threshold N. Specifically, the base station decodes the MSG3 and MsgA (including the content of Msg3) messages sent by the UE, and analyzes the uplink channel environment through MSG3. In TDD, channel reciprocity can be utilized to pre-evaluate the downlink channel environment based on the uplink channel environment parsed by MSG3-DMRS; in FDD, although the uplink and downlink have different carrier frequencies, in one channel path, the uplink and downlink channels have the same physical propagation path (fading coefficient, angle of arrival / departure, time delay). The dB difference between the uplink and downlink channels of FDD is pre-evaluated through the environmental propagation model, assuming Φ. The current channel environment is obtained through MSG3-DMRS. Compared with the measurement reporting values such as SRS and CSI, the accuracy is insufficient. A pre-evaluation factor is introduced in combination with the UE open-loop power control parameters and high-layer parameters such as the base station's HigherlayerfilteredRSRP and PRACH. Among them, the UE open-loop power control parameters and high-layer parameters such as the base station's HigherlayerfilteredRSRP and PRACH reflect the environment of the PRACH channel. The channel and TA data graph of PRACH can be obtained based on the empirical values over a period of time and judged with the channel and TA data graph solved by MSG3-DMRS. If the difference between the standard deviations of the two is greater than the set difference, it indicates that the environmental differences between the two are large, and the CDF graph is formed with the channel data of MSG3-DMRS (relatively accurate). When the probability is less than the set threshold, the corresponding channel condition is the channel threshold a; if the difference between the standard deviations of the two is less than the set difference, it indicates that the current environmental differences between the two are small, and then expectation correction and data averaging processing are performed to form a CDF graph. When the probability is less than the set threshold, the corresponding channel condition is the channel threshold a; in the FDD frequency band, it is corrected through Φ. What is solved by MSG3 is the uplink channel environment, and the downlink channel condition decision threshold is a + Φ.

[0146] Correspondingly, an embodiment of the present application further provides a method for processing access scheduling resources, Figure 3 which is another flowchart of a method for processing access scheduling resources according to an embodiment of the present application, as Figure 3 shown; applied to a terminal, including:

[0147] Step 301: When the terminal meets the handover condition of the partial bandwidth BWP, receive the first information sent by the network device; the first information carries the resource information of the dedicated BWP; the terminal meets the BWP handover condition based on the channel environment information and access information corresponding to the terminal.

[0148] Step 302: Access the dedicated BWP by using the resource information.

[0149] In this embodiment, the terminal may be determined according to the actual situation, which is not limited herein. As an example, the terminal may be a user terminal, denoted as UE.

[0150] In step 301, the network device may be determined according to the actual situation, which is not limited herein. As an example, the network device may be a base station.

[0151] The handover condition of the BWP may be determined according to the actual situation, which is not limited herein. As an example, the handover condition of the BWP may include a first condition and / or a second condition; the first condition represents a first threshold range corresponding to a first TA parameter; the second condition represents a second threshold range corresponding to the first channel environment parameter; both the first condition and the second condition may be determined according to the actual situation, which is not limited herein. As an example, the first condition may be to parse the random access MSG2 and determine that the TA value ∈ [0, N]; the second condition may be to parse the channel environment of MSG3-DMRS and determine that the channel condition ≥ channel threshold a. That the terminal meets the handover condition of the BWP is determined based on the channel environment information and access information corresponding to the terminal may include determining whether the first TA parameter meets the first threshold range to obtain a first result; determining whether the first channel environment parameter meets the second threshold range to obtain a second result; and determining whether the terminal meets the handover condition of the BWP based on the first result and / or the second result. Both the channel environment information and the access information may be determined according to the actual situation, which is not limited herein. As an example, the channel environment information may include a first channel environment parameter; and the access information may include a first time advance TA parameter.

[0152] That the terminal meets the handover condition of the BWP may be determined according to the actual situation, which is not limited herein. As an example, that the terminal meets the handover condition of the BWP may be understood as that the UE meets the condition to initiate an initial BWP handover from msg4 to the dedicated BWP.

[0153] In step 302, the first information is sent to the terminal by accessing the dedicated BWP using the resource information; the resource information of the dedicated BWP carried in the first information may be understood as using the dedicated PDCCH resource in the subsequent access process, reducing the consumption of the common PDCCH CORESET0, thereby ensuring the access of the UE and improving the network radio connection rate index.

[0154] In this embodiment, an optimized method is used to determine whether a UE meets the condition to initiate an initial BWP switch from msg4 to a dedicated BWP, so that the subsequent access process uses dedicated PDCCH resources, reducing the consumption of the common PDCCH CORESET0, thereby ensuring UE access and improving the network radio connection rate index.

[0155] In the embodiment of this application, it is determined whether the terminal meets the BWP switching condition based on the channel environment information and access information corresponding to the terminal; when the terminal meets the BWP switching condition, a first message carrying the resource information of the dedicated BWP is sent to the terminal, so that the terminal accesses the dedicated BWP, reducing the consumption of the common control resource set, thereby ensuring UE access and improving the network radio connection rate index.

[0156] Among them, in one embodiment, the channel environment information includes a first channel environment parameter, and the method further includes:

[0157] Sending a first message of a random access (RA) to the network device; the first message is used for the network device to perform parsing to obtain the power control information corresponding to the terminal; determining the first channel environment parameter based on the power control information.

[0158] In this embodiment, the channel environment information includes a first channel environment parameter; the first channel environment parameter can be determined according to the actual situation and is not limited herein. As an example, the first channel environment parameter may include a channel threshold.

[0159] For easy understanding, an example is given here. Suppose that a large number of random accesses, reconfigurations, and reconstructions and other processes that consume CORESET 0 resources occur within the cell coverage area. At this time, users (quantity X) send random access messages in the same cell. That is, it can be understood as receiving the first message of the RA sent by the terminal; among them, the first message can be determined according to the actual situation and is not limited herein. As an example, the first message may be UE MSG1-Preamble and MsgA-preamble.

[0160] The first message is used for the network device to perform parsing to obtain the power control information corresponding to the terminal; among them, the power control information can be determined according to the actual situation and is not limited herein. As an example, the power control information may be the transmission power.

[0161] In practical applications, assume that a large number of processes that consume CORESET 0 resources, such as random access, reconfiguration, and reconstruction, occur within the cell coverage area. At this time, users (number X) initiate random access in the same cell. Analyze the UE power control information (such as transmit power) in the UE MSG1-Preamble and MsgA-preamble, and the TA values in the MSG2-RAR and MsgB-RAR messages sent by the base station.

[0162] In one embodiment, the access information includes a first time advance TA parameter; the method further includes:

[0163] Receive a second message of a random access response RAR sent by the network device;

[0164] Parse the second message to obtain the first TA parameter.

[0165] In this embodiment, the access information includes a first time advance TA parameter; the TA parameter can be determined according to the actual situation and is not limited herein. As an example, the TA parameter may include a TA value.

[0166] Receive a second message of a random access response RAR sent by the network device; the second message can be determined according to the actual situation and is not limited herein. As an example, the second message may include MSG2-RAR and MsgB-RAR messages.

[0167] In practical applications, the TA values in the MSG2-RAR and MsgB-RAR messages sent by the base station.

[0168] In one embodiment, the switching condition of the BWP includes a first condition and / or a second condition; the first condition represents a first threshold range corresponding to the first TA parameter; the second condition represents a second threshold range corresponding to the first channel environment parameter; determining whether the terminal meets the switching condition of the partial bandwidth BWP based on the channel environment information and access information corresponding to the terminal includes:

[0169] Determine whether the first TA parameter meets the first threshold range to obtain a first result;

[0170] Determine whether the first channel environment parameter meets the second threshold range to obtain a second result;

[0171] Determine whether the terminal meets the switching condition of the BWP based on the first result and / or the second result.

[0172] In this embodiment, the switching condition of the BWP includes a first condition and / or a second condition, which can be understood as the switching condition of the BWP includes the first condition; the switching condition of the BWP includes the second condition; the switching condition of the BWP includes the first condition and the second condition. Both the first condition and the second condition can be determined according to the actual situation and are not limited herein. As an example, the first condition may be to parse the random access MSG2 and determine that the TA value ∈ [0, N]; the second condition may be to parse the channel environment of MSG3-DMRS and determine that the channel condition ≥ channel threshold a.

[0173] The first condition represents a first threshold range corresponding to the first TA parameter; wherein, the first threshold range can be determined according to the actual situation and is not limited herein. As an example, the first threshold range can be denoted as [0, N].

[0174] The second condition represents a second threshold range corresponding to the first channel environment parameter; wherein, the second threshold range can be determined according to the actual situation and is not limited herein. As an example, the second threshold range can be understood as greater than or equal to a.

[0175] Determining whether the first TA parameter satisfies the first threshold range to obtain a first result can be understood as determining whether the first TA parameter satisfies the first threshold range to obtain a first result that the first TA parameter satisfies the first threshold range or the first TA parameter does not satisfy the first threshold range.

[0176] Determining whether the first channel environment parameter satisfies the second threshold range to obtain a second result can be understood as determining whether the first channel environment parameter satisfies the second threshold range to obtain a second result that the first channel environment parameter satisfies the second threshold range or the first channel environment parameter does not satisfy the second threshold range.

[0177] Determining whether the terminal meets the BWP switching condition based on the first result and / or the second result can be understood as determining whether the terminal meets the BWP switching condition based on the first result that the first TA parameter meets the first threshold range or the first TA parameter does not meet the first threshold range and / or the second result that the first channel environment parameter meets the second threshold range or the first channel environment parameter does not meet the second threshold range. As an example, determining whether the terminal meets the BWP switching condition based on the first result and / or the second result may include determining that the terminal meets the BWP switching condition when the first result indicates that the first TA parameter meets the first threshold range and / or the second result indicates that the first channel environment parameter meets the second threshold range; and determining that the terminal does not meet the BWP switching condition when the first result indicates that the first TA parameter does not meet the first threshold range and the second result indicates that the first channel environment parameter does not meet the second threshold range.

[0178] In one embodiment, the BWP switching condition includes a first condition and / or a second condition; the first condition represents a first threshold range corresponding to the first TA parameter; the second condition represents a second threshold range corresponding to the first channel environment parameter; and the method further includes:

[0179] Receiving the first information corresponding to the first terminal for which the first TA parameter sent by the network device meets the first threshold range; the first information carries resource information of the dedicated BWP;

[0180] Accessing the dedicated BWP using the resource information.

[0181] In one embodiment, the method further includes:

[0182] Sending a third message to the network device; the third message is used for the network device to adjust the second threshold range.

[0183] It should be noted that the third message can be determined according to the actual situation and is not limited herein. As an example, the third message may include MSG3 and / or MsgA; MsgA may include the content of MSG3.

[0184] The third message is used for the network device to adjust the second threshold range. As an example, the channel condition is the channel threshold a; the FDD frequency band is corrected by Φ, the uplink channel environment is decoded from MSG3, and the downlink channel condition decision threshold is a + Φ.

[0185] In practical applications, the base station decodes the MSG3 and MsgA (including the content of MSG3) messages sent by the UE. For TDD, the uplink channel environment can be analyzed by using the channel reciprocity through the parsing of MSG3, and the downlink channel environment can be pre-evaluated based on the uplink channel environment parsed by MSG3-DMRS. For FDD, although the uplink and downlink have different carrier frequencies, in a single channel path, the uplink and downlink channels have the same physical propagation path (fading coefficient, angle of arrival / departure, delay). The dB difference between the uplink and downlink channels of FDD is pre-evaluated through the environmental propagation model, assuming Φ. The current channel environment is obtained through MSG3-DMRS. Compared with the measurement reporting values such as SRS and CSI, the accuracy is insufficient. A pre-evaluation factor is introduced by combining the UE open-loop power control parameters and the higher-layer parameters of the base station such as HigherlayerfilteredRSRP and PRACH. Among them, the UE open-loop power control parameters and the higher-layer parameters of the base station such as HigherlayerfilteredRSRP and PRACH reflect the environment of the PRACH channel. The channel and TA data graph of PRACH and the channel and TA data graph solved by MSG3-DMRS can be judged based on the empirical values within a certain period of time. If the difference between the standard deviations of the two is greater than the set difference, it indicates that the environmental differences between the two are large. Then, the channel data of MSG3-DMRS (relatively more accurate) is used to form a CDF graph. When the probability is less than the set threshold, the corresponding channel condition is the channel threshold a. If the difference between the standard deviations of the two is less than the set difference, it indicates that the current environmental differences between the two are small. Then, expectation correction and data averaging are performed to form a CDF graph. When the probability is less than the set threshold, the corresponding channel condition is the channel threshold a. For the FDD band, it is corrected by Φ. The MSG3 decodes the uplink channel environment, and the downlink channel condition decision threshold is a + Φ.

[0186] In one embodiment, the method further includes:

[0187] Receiving, from a network device, the first information of a second terminal whose first channel environment parameter satisfies the second threshold range; the first information carries resource information of a dedicated BWP;

[0188] Using the resource information to access the dedicated BWP.

[0189] It should be noted that the handover conditions of the BWP may include: ① Parsing the random access MSG2 to determine whether the TA value ∈ [0, N]; ② Parsing the channel environment of MSG3-DMRS to determine whether the channel condition ≥ the channel threshold a.

[0190] The first information of the second terminal that receives the first channel environment parameter sent by the network device and meets the second threshold range can be understood as that only the UEs that meet ② can access normally, and the UEs that only meet ① cannot access normally, indicating that the current TA range threshold setting is too small. Then, based on the CDF distribution of TA, increase the probability setting threshold and increase the TA condition decision range N.

[0191] In this embodiment, for the UEs that meet the conditions, when the base station sends msg4 or MsgB, it carries dedicated BWP resource information. After receiving it, the UE performs BWP switching and uses dedicated PDCCH resources for scheduling; for the UEs that meet some conditions, correct them according to the access situation: for the UEs that only meet ②, give priority to executing the dedicated BWP configuration when sending Msg4.

[0192] In practical applications, the access scheduling resource processing method can be specifically understood as an access scheduling resource optimization method, focusing on PDCCH resource scheduling and resource overhead optimization. Through the optimization method, the UE initiates an initial BWP switch from msg4 to a dedicated BWP, which not only ensures differential access for users without measurement reporting, but also ensures a reduction in the consumption of PDCCH CORESET0 resources, enables an increase in the wireless connection rate of users in large-capacity scenarios, an improvement in the access experience, and an increase in spectrum efficiency. This proposal is not only applicable to scenarios with a sharp increase in access users, but especially applicable to complex environments such as large-capacity and high-traffic scenarios to ensure network performance. This solution is also applicable to the two-step access of MsgA + MsgB, where MsgA corresponds to Msg1 and Msg3, and MsgB corresponds to Msg2 and Msg4.

[0193] Detailed elaboration of the technical solution of this application.

[0194] This application proposes an access control resource scheduling optimization method. Specifically, this method evaluates and judges based on conditions such as the TA value, transmission power P, and channel environment in the UE random access message. Through the optimization method, it is judged whether the UE meets the conditions to initiate an initial BWP switch from msg4 to a dedicated BWP, so that the subsequent access process uses dedicated PDCCH resources, reduces the consumption of the public PDCCH CORESET0, and thus ensures UE access and improves the network wireless connection rate index.

[0195] The TA value refers to the TA value in the RAR (Random Access Response) based on MSG2.

[0196] The channel environment refers to the channel environment parsed based on MSG3.

[0197] Specifically, the following is a mechanism process of this method: For ease of description, assume that a large number of processes such as random access, reconfiguration, and reconstruction that consume CORESET 0 resources occur within the cell coverage area. At this time, users (number X) initiate random access in the same cell.

[0198] Step 1: Analyze the UE power control information (such as transmit power) in the UE MSG1-Preamble and MsgA-preamble, and the TA value in the MSG2-RAR and MsgB-RAR messages sent by the base station.

[0199] During the random access process, the base station measures the UE uplink PRACH preamble sequence to obtain UE PRACH uplink open-loop power control related parameters. For example, the transmit power is set by the UE based on factors such as the expected received power configured by the network and path loss. If the UE does not receive the RAR, the UE needs to retransmit the PRACH, and the power climbs, which to a certain extent reflects the current channel environment state. It can be referred to the formula (1):

[0200] P PRACH,b,f,c (i) = min{P CMAX,f,c (i), P PRACH,target,f,c + PL b,f,c} [dBm] (1)

[0201] Where PL involves PL = referenceSignalPower - HigherlayerfilteredRSRP;

[0202] The reference signal power referenceSignalPower is determined by the parameters ss-PBCH-BlockPower and powerControlOffsetSS according to the SSB or CSI-RS related to the PRACH. HigherlayerfilteredRSRP is the RSRP measured when sending the PRACH. By comparing the UE transmit power and the PRACH expected power + path loss value, the minimum value is taken to determine the PRACH power, which contains the signal environment information of the current channel.

[0203] The TA information will be carried in the MAC payload of the RAR (random access response) sent by the base station. The TA accuracy corresponding to different SCS levels is different. After obtaining it, the distance between the UE and the base station can be estimated, which can be understood in combination with Table 1. Table 1 is the TA accuracy table.

[0204] Table 1: TA accuracy table

[0205] Subcarrier Spacing TA Accuracy (seconds) TA Distance (meters) 15 16 * 64 * Tc 78.125 30 16 * 32 * Tc 39.0625 60 16 * 16 * Tc 19.53125 120 16 * 8 * Tc 9.765625

[0206] The 12-bit TA information is carried in the MAC payload of the NR random access procedure. The range of TA is between 0 and 3846. Currently, in some usage scenarios, the TA range is identified by an index (partial content based on different SCS levels); it can be understood in combination with Table 2 and Table 3. Table 2 is the index identifying the TA range; Table 3 is the index identifying the TA range.

[0207] Table 2: Index Identifying TA Range (SCS = 30KHz)

[0208]

[0209]

[0210] Table 3: Index Identifying TA Range (SCS = 15KHz)

[0211] Index TA Range Corresponding Distance Index0 [0，1] [0,39] Index1 [2，3] [39,117] Index2 [4，7] [117,273] Index3 [8，13] [283,508] Index4 [14，25] [508,977] Index5 [26，45] [977,1758] Index6 [46，85] [1758,3320] Index7 [86，185] [3320,7227]

[0212] Set the TA condition decision range [0, N]. Based on "the number of accesses when the TA value of the user during random access is within the interval range N" and "the distribution of TA values (including RAR and MAC CE)", a CDF graph is generated. When the probability is less than the set threshold, the corresponding TA value is the decision threshold N.

[0213] Step 2: The base station decodes the MSG3 and MsgA (including the content of Msg3) messages sent by the UE, and analyzes the uplink channel environment through MSG3.

[0214] TDD can utilize channel reciprocity to pre-evaluate the downlink channel environment based on the uplink channel environment parsed by MSG3-DMRS; for FDD, although the uplink and downlink have different carrier frequencies, in one channel path, the uplink and downlink channels have the same physical propagation path (fading coefficient, angle of arrival / departure, time delay). The dB difference between the uplink and downlink channels of FDD is pre-evaluated through the environmental propagation model, assuming Φ. The current channel environment is obtained through MSG3-DMRS. Compared with the measurement reporting values such as SRS and CSI, the accuracy is insufficient. A pre-evaluation factor is introduced by combining the UE open-loop power control parameters and high-layer parameters such as the base station's HigherlayerfilteredRSRP and PRACH. Among them, the UE open-loop power control parameters and high-layer parameters such as the base station's HigherlayerfilteredRSRP and PRACH reflect the environment of the PRACH channel. The channel and TA data graph of PRACH and the channel and TA data graph solved by MSG3-DMRS can be judged based on the empirical values within a period of time. If the difference between the standard deviations of the two is greater than the set difference, it indicates that the environmental differences between the two are large. Then, a CDF graph is formed with the channel data of MSG3-DMRS (relatively more accurate). When the probability is less than the set threshold, the corresponding channel condition is the channel threshold a; if the difference between the standard deviations of the two is less than the set difference, it indicates that the current environmental differences between the two are small. Then, expectation correction and data averaging are performed to form a CDF graph. When the probability is less than the set threshold, the corresponding channel condition is the channel threshold a; the FDD frequency band is corrected by Φ. What is solved by MSG3 is the uplink channel environment, and the downlink channel condition decision threshold is a + Φ.

[0215] Step 3: Based on TA and the corrected channel quality, determine whether the UE meets the TA condition decision range and the channel threshold. For the UE that meets the conditions, when the base station sends msg4 or MsgB, it carries the dedicated BWP resource information. After the UE receives it, it performs BWP switching and uses the dedicated PDCCH resource for scheduling; for the UE that meets some conditions, corrections are made according to the access situation. This part of the content can be combined Figure 4 for understanding, Figure 4 This is the access schematic diagram of the UE in the embodiment of this application.

[0216] Case 1: For the UE that meets conditions ① and ②, execute Msg4 to send the dedicated BWP configuration, and the subsequent access process transfers to the dedicated BWP:

[0217] Case 2: For the UE that only meets ① and the UE that only meets ②, give priority to executing Msg4 to send the dedicated BWP configuration. If:

[0218] 1. The UE performs normal BWP switching and access, and the threshold is reasonable;

[0219] 2. UEs that only meet ① can access normally, while UEs that only meet ② cannot access normally, indicating that the channel threshold is set too high. Then, based on the channel estimation method mentioned in Step 2, lower the probability limit threshold and reduce the channel threshold.

[0220] 3. UEs that only meet ② can access normally, while UEs that only meet ① cannot access normally, indicating that the current TA range threshold is set too small. Then, based on the CDF distribution of TA mentioned in Step 1, increase the probability setting threshold and increase the TA condition decision range N.

[0221] Case 3: UEs that do not meet ① and ② execute the traditional access process.

[0222] Step 4: When the radio connection establishment rate deteriorates to a certain threshold, return to Step 1.

[0223] In a large-capacity scenario with high network load, the number of burst access users surges, the uplink interference in the cell is severe, the PDCCH aggregation level increases, and a large number of retransmissions, reconstructions, etc. occur, resulting in limited CORESET0 resources, causing users to be unable to access. Solving the congestion of CORESET0 resources seriously affects the radio connection establishment rate of the network; ensuring that the UE can normally initiate BWP switching in msg4 and correctly receive subsequent access process information.

[0224] In this embodiment, mainly in a large-capacity scenario, through optimization methods, the UE switches from msg4 and MsgB to the dedicated BWP, reduces the consumption of CORESET0, and alleviates the low radio connection establishment rate in the heavy load situation. For whether the UE can switch from msg4 and MsgB to the dedicated BWP, conditional judgments are made based on the "TA condition decision range" under the UE location condition and the "channel threshold" based on MSG3 parsing, UE power control parameters, and high-layer parameter settings; for the setting of the "channel threshold", a pre-evaluation factor is introduced in combination with the UE open-loop power control parameters and high-layer parameters such as the base station HigherlayerfilteredRSRP and PRACH to perform expectation correction, perform weighted assignment for channel estimation, and set and correct the deviation through the transmission model in the FDD band; for the correction of the "TA condition decision range" and the "channel threshold", judgments are made based on the actual application situation.

Figure 5 It is a schematic structural diagram of an access scheduling resource processing device according to an embodiment of the present application; as Figure 5 shown, it includes:

[0226] A judgment unit 501, configured to judge whether the terminal meets the switching condition of the partial bandwidth BWP based on the channel environment information and access information corresponding to the terminal.
