Description

Technical Field

[0001] The present invention relates to the field of communication technologies, and particularly to an uplink resource allocation method, apparatus, and base station. Background Art

[0002] In a 5G system, uplink channel resources are divided into PUCCH (Physical Uplink Control Channel) and PUSCH (Physical Uplink Shared Channel). The PUCCH and PUSCH of a user equipment (UE) need to occupy PRBs (Physical Resource Blocks) in the uplink bandwidth of a base station for information transmission. Among them, the PRBs occupied by the PUCCH are pre-allocated by the base station through RRC (Radio Resource Control) signaling, and the PRBs occupied by the PUSCH are dynamically allocated.

[0003] In related technologies, when the user equipment is in an idle state, it still periodically sends information through the PUCCH, such as UCI (Uplink Control Information), CSI (Channel State Information), etc. When the capacity of the 5G system increases and there are a large number of user equipments, the base station needs to allocate a large number of PUCCHs for the user to transmit UCI, thereby occupying a large number of uplink PRBs, reducing the number of available PRBs for the PUSCH, and resulting in waste of PRB resources in the uplink bandwidth of the base station.

Since the power of the PUCCH of the idle user equipment is reduced to below the lower limit threshold, and the PUSCH power of the target user equipment is higher than the upper limit threshold, the interference of the PUCCH of the idle user equipment on the PUSCH of the target user equipment is within the allowed range. The target user equipment in the non-idle state can use the PRB occupied by the PUCCH of the idle user equipment to transmit information for executing the service, and the base station does not need to waste resources to re-initiate RCC signaling, thereby effectively reducing the waste of PRB resources in the uplink bandwidth.

[0058] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. [[ID=ll]]

[0059] To more clearly illustrate the uplink resource configuration method provided by the embodiment of the present invention, an exemplary description will be given below of a possible application scenario of the uplink resource configuration method provided by the embodiment of the present invention. It can be understood that the following examples are only a possible application scenario of the uplink resource configuration method provided by the embodiment of the present invention. In other possible embodiments, the uplink resource configuration method provided by the embodiment of the present invention can also be applied to other possible application scenarios, and the following examples do not impose any restrictions on this.

[0060] Suppose there are a total of 160 PRBs in the uplink bandwidth of the base station, and 400 user equipments are connected to this base station. The base station allocates PRBs for the PUCCH of each UE through RRC signaling, and the PUCCHs of every 8 user equipments are multiplexed on the same PRB. Therefore, the PUCCHs of 400 user equipments altogether occupy 50 PRBs. The remaining 110 PRBs are the PRBs available for the PUSCH of these 400 user equipments to transmit information.

[0061] If all 400 user equipments are in the state of executing services (hereinafter referred to as non-idle state), then all 160 PRBs can transmit information for executing services. At this time, it can be considered that the utilization rate of the PRBs is 100%. However, not all user equipments are in the non-idle state at all times. Some user equipments may be in the idle state during some time periods.

[0062] Suppose that 320 user equipments are in the idle state during a certain period. However, these 320 user equipments still upload information such as UCI and CSI through PUCCH. Since these 320 user equipments are in the idle state, the information such as UCI and CSI uploaded by these 320 user equipments is not information for executing services. And the PUCCH of these 320 user equipments occupies 40 PRBs, and these 40 PRBs are unavailable for the PUSCH of user equipments in the non-idle state. Therefore, user equipments in the non-idle state cannot transmit information for executing services through these 40 PRBs. Therefore, only 120 PRBs can be used to transmit information for executing services at this time, resulting in a waste of 25% of the PRB resources.

[0063] The base station can adjust the PRBs allocated to the PUCCH of each user equipment by reinitiating the RCC signaling, so that the PUCCH of user equipments in the idle state no longer occupies PRBs. However, reinitiating the RCC signaling by the base station also consumes uplink resources, so the problem of wasted uplink resources cannot be solved.

[0064] Based on this, an embodiment of the present invention provides an uplink resource allocation method, which can be seen Figure 1 , Figure 1 shown in a possible flowchart of the uplink resource configuration method provided by an embodiment of the present invention, which may include:

[0065] S10**1**, send a first DCI to the idle user equipment, where the first DCI is used to instruct the idle user equipment to reduce the power of the PUCCH to below a lower threshold, and the lower threshold is lower than the minimum power required for the base station to parse the PUCCH.

[0066] S10**2**, after determining that the power of the PUCCH of the idle user equipment is reduced to below a preset lower threshold, configure the PRBs occupied by the PUCCH of the idle user equipment as reusable PRBs available for PUSCH.

[0067] S10**3**, send a second DCI to the target user equipment, where the second DCI is used to instruct the first PRBs that the PUSCH of the target user equipment can use, and the first PRBs used by the PUSCH include the above-mentioned reusable PRBs. The target user equipment is a user equipment in the non-idle state, and the PUSCH power of the target user equipment is higher than a preset upper threshold, and the preset upper threshold is higher than the minimum power required for the base station to parse the PUSCH.

[0068] By selecting this embodiment, the base station can indicate to the user equipment in the idle state to reduce the power of the PUCCH (Physical Uplink Control Channel) to below the lower threshold by sending DCI (Downlink Control Information) to the user equipment, and enable the PUSCH (Physical Uplink Shared Channel) of the target user equipment with the power of the PUSCH higher than the upper threshold to share the same PRB (Physical Resource Block) with the PUCCH of the idle user equipment. Since the power of the PUCCH of the idle user equipment is reduced to below the lower threshold and the lower threshold is lower than the minimum power required for the base station to decode the PUCCH, and the power of the PUSCH of the target user equipment is higher than the upper threshold, the interference of the PUCCH of the idle user equipment to the PUSCH of the target user equipment is within the allowable range. This enables the target user equipment in the non-idle state to use the PRB occupied by the PUCCH of the idle user equipment to transmit information for executing services, and the base station does not need to waste resources to re-initiate the RRC (Radio Resource Control) signaling, so the waste of PRB resources in the uplink bandwidth can be effectively reduced. Among them, the allowable range can be set according to experience or obtained through experimental tests.

[0069] In S101, the base station can send the first DCI carrying the power control instruction to the idle user equipment through the PDCCH (Physical Downlink Control Channel) so that the idle user equipment executes the power control instruction, and the power control instruction is used to indicate the idle user equipment to reduce the power of the PUCCH of the idle user equipment to below the preset lower threshold.

[0070] The idle user equipment is the user equipment in the idle state among the user equipment accessing the base station. The idle state refers to the state without services, and the idle user equipment can be one user equipment or multiple user equipment. In a possible embodiment, to fully reduce the waste of PRB resources in the uplink bandwidth, the idle user equipment is all the user equipment in the idle state among the user equipment accessing the base station.

[0071] The lower threshold can be different according to different application scenarios. Exemplarily, in a possible embodiment, the lower threshold can be -125 dB (decibel), and in other possible embodiments, it can also be other values, such as -120 dB, -110 dB, etc. The lower threshold can be set according to experience or obtained through experimental tests. The lower threshold should be lower than the minimum power required for the base station to decode the PUCCH and does not include this number.

[0072] After S101, the base station can determine whether the power of the PUCCH of the idle user equipment has dropped below a preset lower threshold according to the UCI and CSI sent by the idle user equipment to the base station through the PUCCH. When it is determined that the power of the PUCCH of the idle user equipment has dropped below the lower threshold, S102 is executed.

[0073] In S102, since the power of the PUCCH of the idle user equipment has dropped below the preset lower threshold, theoretically, if the PUSCH of the non-idle user equipment multiplexes the PRB occupied by the PUCCH of the idle user equipment, and the power of the PUSCH of the non-idle user equipment is high enough, the interference of the UCI, CSI and other information transmitted by the idle user equipment through the PUCCH to the service data transmitted by the non-idle user equipment through the PUSCH is low and will not affect the base station's normal parsing of the service data transmitted by the non-idle user equipment through the PUSCH. Therefore, the PRB occupied by the PUCCH of the idle user equipment can be configured as a reusable PRB and made available for the PUSCH.

[0074] In S103, the base station can send a second DCI carrying a frequency domain resource allocation instruction to the target user equipment through the PDCCH, so that the target user equipment executes the frequency domain resource allocation instruction. The frequency resource allocation instruction is used to indicate the first PRB that the PUSCH of the target user equipment can use, and the first PRB that the PUSCH of the target user equipment can use includes the reusable PRB.

[0075] The target user equipment can be one user equipment or multiple user equipment. In a possible embodiment, to fully improve the uplink throughput capacity, the target user equipment is all non-idle user equipment among the user equipment accessing the base station and whose PUSCH power is greater than a preset upper threshold. The non-idle state refers to the state of executing services.

[0076] The upper threshold can be different according to different application scenarios. Exemplarily, in a possible embodiment, the upper threshold can be -80 dB (decibels), and in other possible embodiments, it can also be other values, such as -75 dB, -70 dB, etc. The upper threshold can be set according to experience or obtained through experimental tests. The upper threshold should be higher than the minimum power required for the base station to parse the PUSCH.

[0077] In some application scenarios, the power of the PUSCH of all user equipments that are not in the idle state and are connected to the base station may be lower than the preset upper limit threshold. That is, there is no target user equipment at this time. In this application scenario, since there is no target user equipment, S103 may not be executed, but S101 and S102 may be executed, that is, only the power of the PUCCH of the idle user equipment is reduced, and the PRB occupied by the PUCCH of the idle user equipment is configured as the PRB available for the PUSCH as the reusable PRB. For the convenience of description, the scenario with a target user equipment will be described below. The principle for the scenario without a target user equipment is the same, so it will not be elaborated here.

[0078] In this embodiment, the execution timing of step S101 may be different according to different application scenarios. Exemplarily, it may be that the base station monitors the states of all user equipments connected to it. When a user equipment in the idle state is detected, step S101 may be executed.

[0079] The base station may monitor the downlink service buffer amount of each user equipment. If the downlink service buffer amount of the user equipment is greater than the preset stock threshold, the base station may determine that the user equipment is in the non-idle state. If the downlink service buffer amount of the user equipment is not greater than the preset buffer threshold, the base station may determine that the user equipment is in the idle state.

[0080] It can be understood that if the user equipment is in the non-idle state, that is, the user equipment is executing a service, then since the service data of the service being executed by the user equipment will pass through the base station, theoretically the downlink service buffer amount of this user equipment is large. If the user equipment is in the idle state, that is, the user equipment has no service, then theoretically there will be no service data of this user equipment passing through the base station. Therefore, the downlink service buffer amount of the user equipment is small or even zero. Therefore, the state of the user equipment can be judged by the downlink service buffer amount.

[0081] When it is monitored that a user equipment enters the idle state, S101 is executed. It may also be that when the number of user equipments entering the idle state is more than the preset number threshold, S101 is executed.

[0082] In a possible embodiment, it may also be determined whether to execute step S101 based on whether the PRB constraint rate is higher than the preset ratio threshold. Among them, the PRB constraint rate is used to represent the ratio of the PRB occupied by the PUCCH of all non-idle devices connected to the base station to the total number of PRBs included in the uplink bandwidth of the base station. Exemplarily, assuming that the PRB occupied by the PUCCH of all non-idle devices connected to the base station is 40 and the total number of PRBs included in the uplink bandwidth of the base station is 160, the PRB constraint rate may be 25%.

[0083] If the PRB constraint rate is higher than the preset ratio threshold, then S101 is executed. If the PRB constraint rate is not higher than the preset ratio threshold, then the execution of S101 is rejected. This ratio threshold can be set according to experience or obtained through experimental testing. For example, it can be determined by investigating the communication quality and PRB constraint rate of multiple cells, and based on the corresponding relationship between the communication quality and PRB constraint rate obtained from the investigation. For example, assume that relevant personnel investigated multiple cells and found that the communication quality of cells with a PRB constraint rate below 10% is good, while the communication quality of some cells with a PRB constraint rate above 10% is poor. Then the ratio threshold can be determined as 10%.

[0084] It can be understood that the higher the proportion of PRBs occupied by the PUCCH of a non-idle device in the PRBs included in the base station's uplink bandwidth, the more serious the waste of PRB resources in the uplink bandwidth. The lower the proportion of PRBs occupied by the PUCCH of a non-idle device in the PRBs included in the base station's uplink bandwidth, the less serious the waste of PRB resources in the uplink bandwidth.

[0085] Moreover, the base station sending DCI to the user equipment also requires occupying certain system resources of the base station. Therefore, if the PRB constraint rate is not higher than the preset ratio threshold, it can be considered at this time that the waste of PRB resources is not serious and there is no need to reduce the waste of PRB resources. Therefore, the execution of S101 is rejected. If the PRB constraint rate is higher than the preset ratio threshold, it can be considered at this time that the waste of PRB resources is serious and it is necessary to reduce the waste of PRB resources. Therefore, S101 is executed.

[0086] For a clearer description of the uplink resource configuration method provided by the embodiments of the present invention, reference can be made to Figure 2 , Figure 2 which shows an interaction schematic diagram of the uplink resource configuration method provided by the embodiments of the present invention and may include:

[0087] S201, the base station sends a first DCI to an idle user equipment.

[0088] Wherein, the first DCI is used to instruct the idle user equipment to reduce the power of the PUCCH to below the lower threshold, and the lower threshold is lower than the minimum power required for the base station to parse the PUCCH.

[0089] S202, the idle user equipment reduces the power of the PUCCH to below the lower threshold.

[0090] The idle user equipment reduces the power of the PUCCH to below the lower threshold according to the instruction of the first DCI.

[0093] S204. The base station determines whether the power of the PUCCH of the idle user equipment is reduced below the lower threshold according to the UCI and CSI.

[0094] S205. After the base station determines that the power of the PUCCH of the idle user equipment is reduced below the lower threshold, the base station configures the PRB occupied by the PUCCH of the idle user equipment as a reusable PRB and makes it available for the PUSCH.

[0095] This step is the same as the foregoing 102, and the relevant description about S102 can be referred to, which will not be elaborated here.

[0100] See Figure 3 , Figure 3 shown in another flowchart of the uplink resource configuration method provided by the embodiment of the present invention, which may include:

[0101] S301. Send a first DCI to the idle user equipment, where the first DCI is used to indicate the idle user equipment to reduce the power of the PUCCH below the lower threshold, and the lower threshold is lower than the minimum power required for the base station to parse the PUCCH.

[0102] This step is the same as the foregoing S101, and the relevant description about S101 can be referred to, which will not be elaborated here.

[0103] S302. Determine whether the idle user equipment resumes services.

[0104] The method for determining whether the idle user equipment resumes services may be different according to different application scenarios, and possible determination methods will be exemplarily described below, so it will not be elaborated here. Resuming services in this article may refer to having resumed services and / or about to resume services, where about to resume services means resuming services within a certain time period, and the certain time period may be different according to different application scenarios.

[0105] S303. After determining that the power of the PUCCH of the idle user equipment is reduced below a preset lower threshold, configure the PRBs occupied by the PUCCH of the idle user equipment as reusable PRBs available for the PUSCH.

[0106] This step is the same as the aforementioned S102. For the relevant description of S102, please refer to the foregoing, and it will not be elaborated here. The base station may determine whether the power of the PUCCH of the idle user equipment is reduced below the preset lower threshold according to the UCI and CSI sent by the idle user equipment to the base station via the PUCCH after S201. When it is determined that the power of the PUCCH of the idle user equipment is reduced below the lower threshold, S203 is executed.

[0107] S304. Send a second DCI to the target user equipment. The second DCI is used to indicate the first PRBs that the PUSCH of the target user equipment can use, and the first PRBs used by the PUSCH include the reusable PRBs.

[0109] S305. If the idle user equipment resumes services, send a third DCI to the idle user equipment. The third DCI is used to indicate the idle user equipment to increase the power of its PUCCH.

[0110] The base station may send the third DCI carrying a power control instruction to the idle user equipment via the PDCCH, so that the idle user equipment executes the power control instruction, and the power control instruction is used to indicate the idle user equipment to increase the power of the PUCCH.

[0111] The power of the PUCCH of the idle user equipment after increasing is not less than the power required for executing services. The power of the PUCCH of the idle user equipment may be increased to the power before reduction, or may be increased to other power other than the power before reduction. For example, assume that before executing S301, the power of the PUCCH of the idle user equipment is -100 dB, and when executing S301, the power of the PUCCH of the idle user equipment is reduced to -130 dB. Then when executing S303, the power of the PUCCH of the idle user equipment may be increased to -100 dB, or may be increased to other power other than -100 dB, such as -95 dB, -105 dB, etc.

[0112] S306. If the idle user equipment resumes services, configure the reusable PRBs as PRBs unavailable for the PUSCH.

[0113] Since the power of the PUCCH of the idle user equipment has increased, theoretically, if the PUSCH of the non-idle user equipment multiplexes the PRBs occupied by the PUCCH of the idle user equipment, the interference of the UCI, CSI, etc. information transmitted by the idle user equipment through the PUCCH to the service data transmitted by the non-idle user equipment through the PUSCH is relatively high, which will affect the base station's normal parsing of the service data transmitted by the non-idle user equipment through the PUSCH. Therefore, the reusable PRBs can be configured as PRBs unavailable for PUSCH.

[0114] S307. Send a fourth DCI to the target user equipment. The fourth DCI is used to indicate the second PRBs that the PUSCH of the target user equipment can use, and the second PRBs used by the PUSCH do not include the reusable PRBs.

[0115] The base station can send a fourth DCI carrying a frequency domain resource allocation instruction to the target user equipment through the PDCCH, so that the target user equipment executes the frequency domain resource allocation instruction. The frequency resource allocation instruction is used to indicate the second PRBs that the PUSCH of the target user equipment can use, and the second PRBs that the PUSCH of the target user equipment can use do not include the reusable PRBs.

[0116] The idle user equipment may not always be in an idle state. For example, the idle user equipment may resume services after a certain period of time. If the power of the PUCCH of the idle user equipment is still lower than the lower threshold, it may cause the idle user equipment to be unable to execute services normally after resuming services. By selecting this embodiment, the idle user equipment can execute services normally after resuming services, that is, this technical problem can be solved.

[0117] For a clearer description of the uplink resource configuration method provided by the embodiments of the present invention, reference can be made to Figure 4 , Figure 4 As shown in

[0118] S401. The base station sends a first DCI to the idle user equipment.

[0119] Among them, the first DCI is used to instruct the idle user equipment to reduce the power of the PUCCH below the lower threshold, and the lower threshold is lower than the minimum power required for the base station to parse the PUCCH.

[0120] S402. The idle user equipment reduces the power of the PUCCH below the lower threshold.

[0121] The idle user equipment reduces the power of the PUCCH below the lower threshold according to the indication of the first DCI.

[0122] S403, the idle user equipment sends UCI and CSI to the base station.

[0123] The idle user equipment sends UCI and CSI to the base station through the PUCCH.

[0124] S404, the base station determines whether the power of the PUCCH of the idle user equipment is reduced below the lower threshold according to the UCI and CSI.

[0125] S405, after determining that the power of the PUCCH of the idle user equipment is reduced below the lower threshold, the base station configures the PRB occupied by the PUCCH of the idle user equipment as a reusable PRB and configures it as a PRB available for the PUSCH.

[0126] This step is the same as the foregoing S102, and the relevant description about S102 can be referred to, and will not be elaborated here.

[0127] S406, the base station sends a second DCI to the target user equipment.

[0128] The second DCI is used to indicate the first PRB that the PUSCH of the target user equipment can use.

[0129] S407, the target user equipment configures the first PRB that the PUSCH of the target user equipment can use, and the first PRB used by the PUSCH includes the reusable PRB.

[0130] The target user equipment configures the first PRB that the PUSCH of the target user equipment can use according to the indication of the second DCI.

[0131] S408, the base station determines whether the idle user equipment resumes services.

[0132] How the base station determines whether the idle user equipment resumes services will be described in subsequent embodiments and will not be elaborated here.

[0133] S409, if the idle user equipment resumes services, the base station configures the reusable PRB as a PRB unavailable for the PUSCH.

[0134] This step is the same as the foregoing S306, and the relevant description about S306 can be referred to, and will not be elaborated here.

[0135] S410, if the idle user equipment resumes services, the base station sends a third DCI to the idle user equipment.

[0136] The third DCI is used to instruct the idle user equipment to increase the power of its PUCCH. It can be understood that Figure 4 The timing diagram shown is only one possible example. In other possible embodiments, S410 may also be executed before S409, or may be executed in parallel with or alternately with S409. This embodiment does not limit this. Similarly, in other possible embodiments, S410 may also be executed after S411, or may be executed in parallel with or alternately with S411.

[0137] S411, if the idle user equipment resumes services, the base station sends a fourth DCI to the target user equipment.

[0138] The fourth DCI is used to indicate the second PRBs that the PUSCH of the target user equipment can use.

[0139] S412, the idle user equipment increases the power of the PUCCH.

[0140] The idle user equipment increases the power of its PUCCH according to the indication of the third DCI.

[0141] S413, the target user equipment configures the second PRBs that the PUSCH of the target user equipment can use. The second PRBs used by the PUSCH do not include reusable PRBs.

[0142] The target user equipment configures the second PRBs that the PUSCH of the target user equipment can use according to the indication of the fourth DCI.

[0143] To more clearly illustrate the uplink resource configuration method provided by the embodiments of the present invention, how to determine whether the idle user equipment resumes services will be described below.

[0144] It can be seen Figure 5 , Figure 5 shown is a flowchart of a service resumption detection method provided by the embodiments of the present invention, which may include:

[0145] S501, send a fifth DCI to the idle user at a preset period. The fifth DCI is used to indicate the third PRBs that the PUSCH of the idle user equipment can use.

[0146] The base station may send the fifth DCI carrying a frequency domain resource allocation instruction to the idle user equipment through the PDCCH, so that the idle user equipment executes the frequency domain resource allocation instruction. The frequency domain resource allocation instruction is used to instruct the idle user equipment to configure the third PRBs as the PRBs available to the idle user equipment.

[0147] The preset period can be set according to actual requirements. The longer the preset period is, the fewer PRB resources in the uplink bandwidth wasted due to service recovery detection. The shorter the preset period is, the more accurate the service recovery detection is.

[0148] The number of the third PRBs can vary according to different actual requirements. In one possible embodiment, to reduce the PRB resources in the uplink bandwidth wasted due to service recovery detection, the number of the third PRBs is 1. In other possible embodiments, the third PRBs can also include 2 PRBs, 3 PRBs or other numbers of PRBs, and this embodiment does not limit this.

[0149] S502, monitor the downlink service buffer amount of the idle user equipment.

[0150] It can be understood that if the idle user equipment resumes services, that is, the idle user equipment starts to execute services, then since the service data of the services executed by the idle user equipment will pass through the base station, theoretically the downlink service buffer amount of the idle user equipment is large. If the idle user equipment does not resume services, that is, the user equipment has no services, then theoretically no service data of the idle user equipment will pass through the base station, so the downlink service buffer amount of the idle user equipment is small or even zero. Therefore, it is possible to determine whether the idle user equipment resumes services by the downlink service buffer amount.

[0151] S503, if the downlink service buffer amount of the idle user equipment is greater than the preset stock threshold, determine that the idle user equipment resumes services.

[0152] S504, if the downlink service buffer amount of the idle user equipment is not greater than the preset stock threshold, determine that the idle user equipment does not resume services.

[0153] Selecting this embodiment can enable the base station to determine whether the idle user equipment resumes services by monitoring the downlink service buffer amount. Thus, the power of the PUCCH of the idle user equipment can be adjusted in a timely manner so that the idle user equipment can execute services normally after resuming services.

[0154] In another possible embodiment, it can also be that when receiving the uplink synchronization information sent by the idle user equipment through the PRACH (Physical Random Access Channel) after sending a service request, it is determined that the idle user equipment resumes services, where the uplink synchronization information is used to establish uplink synchronization between the base station and the idle user equipment. It can be understood that the idle user equipment will send uplink synchronization information to the base station through the PRACH within the first special time slot after sending a service request.

[0155] By selecting this embodiment, the characteristic that an idle user equipment needs to re - establish uplink synchronization after resuming services can be utilized, enabling the base station to determine that the idle user equipment has resumed services after receiving the uplink synchronization information sent by the idle user equipment. Thus, the base station can timely determine that the idle user equipment has resumed services.

[0156] Next, the uplink resource configuration method provided by the embodiments of the present invention will be described in conjunction with user equipment, and reference can be made to Figure 6 , including:

[0157] S601, The user equipment accesses the base station.

[0158] S602, The base station allocates PRBs for the PUCCH of each user equipment.

[0159] S603, The base station periodically monitors the service execution status of each user equipment.

[0160] In this embodiment, the service execution status of the user equipment may include an idle state and a non - idle state.

[0161] S604, The base station determines whether the user equipment is in an idle state. If the user equipment is in an idle state, the base station executes S605. If the user equipment is not in an idle state, the base station executes S609.

[0162] S605, The base station sends a first DCI to the idle user equipment, and the first DCI is used to instruct the idle user equipment to reduce the power of the PUCCH to below a preset lower threshold.

[0163] This step is the same as the aforementioned S101. For relevant descriptions, reference can be made to the relevant description of S101, and details will not be repeated here.

[0164] S606, After the base station determines that the power of the PUCCH of the idle user equipment has been reduced to below the preset lower threshold, the PRB occupied by the PUCCH of the idle user equipment is configured as a PRB available for the PUSCH as a reusable PRB.

[0165] S607, The base station periodically determines whether the idle user equipment has resumed services.

[0166] Among them, the period of S607 may be the same as or different from the period in S403. In a possible embodiment, the period in S607 is greater than the period in S403.

[0167] S608, If the idle user equipment resumes services, the base station sends a third DCI to the idle user equipment, and the third DCI is used to instruct the idle user equipment to increase the power of its PUCCH.

[0168] This step is the same as the aforementioned S305. For the relevant description, reference can be made to the aforementioned S203 and will not be elaborated here.

[0169] S609. The base station determines whether the power of the PUSCH of the user equipment is higher than a preset upper threshold. If the power of the PUSCH of the user equipment is higher than the upper threshold, S610 is executed; if the power of the PUSCH of the user equipment is not higher than the upper threshold, S611 is executed.

[0170] S610. The base station sends a second DCI to the user equipment, and the second DCI is used to indicate the first PRB that the PUSCH of the target user equipment can use.

[0171] It can be understood that if the power of the PUSCH of the user equipment is higher than the preset upper threshold, it can be determined that the user equipment is the aforementioned target user equipment. And the over-powered PUCCH is reduced to the PUCCH of the idle user equipment. Therefore, S610 is that the base station sends a second DCI to the target user equipment.

[0172] S611. The base station keeps the available PRB configured for the PUSCH of the user equipment unchanged.

[0173] S612. After the user equipment in the idle state sends a service request, it sends uplink synchronization information to the base station through the PRACH, so that the base station executes S608.

[0174] If the user equipment in the idle state does not resume the service, the current state can be maintained unchanged.
