Description

Technical Field

[0001] This application relates to the field of communications, and in particular to a scheduling method, an overlapping coverage determination method, an apparatus, a communication device, and a storage medium. Background Technology

[0002] With socio-economic development, high-rise buildings and residential complexes have become widespread. This has led to the adoption of indoor distributed systems (IDS) in communication network construction to cover all floors of high-rise buildings vertically, addressing issues of poor indoor signal strength and the need to absorb the capacity of macro base stations. However, the introduction of IDS requires that different floors not house cells on the same frequency to avoid co-channel interference. Given the limited availability of communication frequency resources, reusing frequencies within the vertical space is necessary to improve resource utilization. This results in a large number of existing indoor coverage cells (IDCs) and a complex networking environment, with potential interference between IDCs and between IDCs and outdoor cells.

[0003] Existing service channels can use Channel State Information-Resource Indicator (CSI-RS) to report RSRP and Signal to Interference plus Noise Ratio (SINR) to reflect the channel environment of the service channel. However, CSI-RS does not have neighbor cell configuration, meaning that the Physical Cell Identifier (PCI) of the cell cannot be obtained from CSI-RS, and neighbor cell information cannot be obtained, which means that the interference level of 5G NR neighbor cell service channels cannot be obtained.

[0116] The present invention will be further described in detail below with reference to the embodiments, starting with a description of the relevant technologies.

[0117] With the continuous increase in the number of mobile users, the communication quality of users inside buildings is receiving increasing attention. Indoor distributed systems are increasingly providing coverage for scenarios such as office buildings, subways, residential areas, and shopping malls, ensuring call quality for users in these areas. An indoor distributed cell refers to a cell of base stations serving an indoor distributed system, while an outdoor cell refers to a cell of outdoor macro base stations. The term "indoor" includes relatively enclosed spaces such as buildings, stadiums, and subways.

[0118] To address the issue of co-channel interference between indoor and outdoor locations, a proposed interference reduction scheme is presented. This scheme primarily utilizes the Xn interface between indoor and outdoor sites to exchange indoor and outdoor service scheduling information and reference signal configuration information. Indoor distributed systems (DPS) can avoid interference from outdoor macro base stations by allocating scheduling resources or by adjusting the transmission beam direction and power outdoors. However, using the Xn interface to exchange real-time scheduling and reference signal configuration information results in a high traffic volume on the Xn interface. Furthermore, the processing delay after the real-time scheduling information is exchanged and then processed by the outdoor macro base station or indoor micro base station significantly impacts the interference reduction effect.

[0119] Regarding overlapping cell coverage, let's first explain the relevant definitions of overlapping coverage.

[0120] Overlapping coverage cell percentage: The percentage of cells in the Measurement Report (MR) sample points that meet the following preset conditions and have 3 or more neighboring cells at the same frequency is greater than 5%.

[0121] Sample point overlap coverage: The proportion of MR sample points that have a number of neighboring cells of the same frequency that meet the following conditions greater than or equal to 3.

[0122] The preset conditions include:

[0123] 1) The voltage level difference between neighboring cells at the same frequency and the main cell is greater than -6dB;

[0124] 2) The reference signal receiving power (RSRP) of the main cell is greater than 110dBm.

[0125] It can be seen that the determination of overlapping coverage is mainly based on the level difference and RSRP. The existing 5G (5th Generation Mobile Communication Technology) New Radio (NR) overlapping coverage indication cannot reflect the 5G NR service channel. The average overlapping coverage cell indication of existing 5G NR is over 20% (compared to 2-3% for 4G), but the average service channel rate can still meet the good point rate of 800Mbps. This is because 4G Long Term Evolution (LTE) uses wide beams; both the service beam and the broadcast beam are 65-degree wide beams. The RSRP of the broadcast channel can reflect the RSRP of the service channel, and the broadcast beam can reflect the service channel beam, including the serving cell retention quality and neighboring cell beam interference. Currently, 5G NR and 4G LTE are deployed at co-location sites. The 5G Synchronization Signal and PBCH block (SSB) uses beamforming, with a beamforming gain 9dB higher than 4G LTE. This naturally results in higher coverage compared to 4G due to the overlap with 4G. Furthermore, 5G NR uses narrow beams, while both the service beam and the broadcast beam are 15-degree wide beams. In scenarios where the broadcast and service beams are misaligned, the broadcast beam cannot fully reflect the performance of the service channel beam; it can only reflect the performance of the service beam that is encountered. The performance of misaligned beams cannot be reflected. This leads to the overlapping coverage reported by 5G NR using the broadcast beam not accurately reflecting the cell status of the terminal.

[0126] Based on this, the scheduling method provided in this embodiment of the invention involves a first network device receiving feedback information sent by a first terminal; determining a first BLER of at least one PRB based on the feedback information; determining a first PRB based on the first BLER of each PRB; and scheduling the resources of the first PRB for the first terminal.

[0127] The overlapping coverage determination method provided in this embodiment of the invention involves a second network device receiving feedback information sent by at least one second terminal serving a target cell; determining a second BLER of the target cell based on the feedback information sent by the at least one second terminal; and determining an overlapping coverage result based on the second BLER.

[0128] Thus, by utilizing BLER to reflect the premise of interference, and by statistically analyzing the BLER of the service channel reported by the terminal, the interference of different resources on the service channel can be reflected. This information can be used to enhance the indoor distribution station scheduling algorithm, update the overlapping coverage index, reduce indoor and outdoor co-channel interference, and enhance the overlapping coverage network management index capability.

[0129] The present invention will be further described in detail below with reference to the embodiments.

[0130] Figure 1 A flowchart illustrating a scheduling method provided in an embodiment of the present invention; as shown Figure 1 As shown, the method is applied to a first network device; the method includes:

[0131] Step 101: Receive feedback information sent by the first terminal;

[0132] Here, the feedback information can be used to reflect whether the service channel is being interfered with;

[0133] Step 102: Based on the feedback information, determine the first BLER of at least one PRB;

[0134] Step 103: Determine the first PRB based on the first BLER of each PRB, and schedule the resources of the first PRB for the first terminal.

[0135] In some embodiments, the network device may be a device for implementing an indoor distributed cell, such as an indoor distribution station or a node in an indoor distributed system.

[0136] The first terminal is the terminal serving the indoor distributed antenna system (DAS) cell, and can also be called an indoor distributed antenna system terminal. Examples include mobile phones, smartphones, laptops, digital radio receivers, personal digital assistants (PDAs), tablet computers (PADs), portable multimedia players (PMPs), wearable devices (such as smart bracelets, smartwatches, etc.), navigation devices, etc.

[0137] In some embodiments, receiving feedback information sent by the first terminal includes:

[0138] Receive feedback information for the scheduled data block sent by the first terminal; the feedback information includes: acknowledgment (ACK) and negative acknowledgment (NACK).

[0139] Specifically, the indoor distribution station can schedule downlink data to the indoor terminal, namely the first terminal, and the first terminal sends feedback information (i.e., ACK / NACK) according to the scheduled data block.

[0140] In some embodiments, determining the first BLER of at least one PRB based on the feedback information includes:

[0141] For each PRB, the first BLER of the PRB is determined based on the feedback information in each time slot.

[0142] Specifically, the indoor distribution station marks the number of ACKs or NACKs based on the time-frequency domain location of the resource in the feedback information sent by the first terminal. After a time period T1, it counts the first BLER of each PRB; that is, the number of ACKs in the time period T1 / (number of ACKs + number of NACKs) and uses the result as the first BLER of the corresponding PRB.

[0143] Within the T1 time window, when counting ACK and NACK counts by PRB, if multiple PRBs are scheduled in the same data block, the same ACK and NACK counts or SINR values ​​are counted for each PRB.

[0144] The indoor distribution station allocates resources to terminals based on the BLER (Browser Interruption Rate) per terminal per time slot per PRB, specifically allocating resources with lower BLERs to terminals. The resource scheduling method based on PRB BLER provided in this embodiment of the invention eliminates the need for subband SINR feedback, requiring only terminal ACK / NACK feedback for statistical analysis. This avoids the significant PUCCH resource consumption associated with subband SINR feedback, thus reducing overhead.

[0145] In some embodiments, determining the first PRB based on the first BLER of each PRB and scheduling the resources of the first PRB for the first terminal includes:

[0146] Based on the first BLER of each PRB, a first PRB that satisfies a first preset condition is determined; the first preset condition includes: the first BLER is lower than a first threshold.

[0147] The resources of the first PRB are scheduled for the first terminal; the resources of the first PRB are used by the first terminal for data transmission.

[0148] Here, the number of PRBs with a first BLER lower than the first threshold may be one or more. When there are multiple PRBs, the PRB with the lowest first BLER can be selected as the first terminal scheduling resource; or, any one of them can be selected as the first terminal scheduling resource.

[0149] In practical applications, considering that the PRB of a high BLER may decrease after a period of time, i.e., the interference is eliminated, the scheduling can be restored after a period of time.

[0150] Based on this, in some embodiments, the method further includes:

[0151] Determine a second PRB that meets a second preset condition; the second preset condition includes: a first BLER exceeding a second threshold.

[0152] Stop scheduling resources of the second PRB and record the duration of the stop scheduling; when the duration of the stop scheduling exceeds a first duration threshold, resume scheduling resources of the second PRB.

[0153] In some embodiments, the method further includes:

[0154] Determine a second PRB that meets a second preset condition; the second preset condition includes: a first BLER exceeding a second threshold.

[0155] Stop scheduling the resources of the second PRB, configure Channel State Information-Interference Measurement (CSI-IM) for the resource location of the second PRB, and obtain the measurement results;

[0156] After determining from the measurement results that there is no interference at the resource location of the second PRB, the scheduling of the resources of the second PRB is resumed.

[0157] Specifically, after a period of time (T2), when scheduling terminal resources, the indoor distribution station can configure CSI-IM at the resource location of the PRB with high BLER of the first terminal to test whether the interference at the interference location still exists. If it does not exist, the terminal resource scheduling is restored.

[0158] The first threshold, the second threshold, T1, and T2 mentioned above can be set based on actual application requirements, and the specific values ​​are not limited here.

[0159] In practical applications, resource scheduling can also be combined with signal-to-interference-plus-noise ratio (SINR) to further achieve precise scheduling.

[0160] Based on this, in some embodiments, the method further includes: determining a first SINR of at least one PRB;

[0161] Accordingly, scheduling resources of the first PRB for the first terminal based on the first BLER of each PRB includes:

[0162] The first PRB is determined based on the first BLER and first SINR of each PRB, and the resources of the first PRB are scheduled for the first terminal.

[0163] In some embodiments, determining the first PRB based on the first BLER and first SINR of each PRB includes:

[0164] Based on the first BLER and first SINR of each PRB, determine the first PRB that satisfies the third preset condition;

[0165] The conditions for satisfying the third preset condition include: the first BLER is lower than the first threshold and the first SINR is higher than the first SINR threshold.

[0166] In practical applications, scheduling based on PRB (Plain Borough Rate) and / or SINR can be added to the existing channel quality information (CQI) and quality of service (QoS) class identifier (QCI) priority scheduling algorithm based on full-band SINR. The added measurement events or metrics indicate whether the BLER of the service channel is greater than a certain value or whether the SINR value of the service channel is less than a certain threshold within a certain period.

[0167] In some embodiments, the method further includes:

[0168] Determine the location of the first terminal in the indoor distribution system scenario;

[0169] Corresponding to the location being in the first area of ​​the indoor distribution scenario, resources for the first terminal to schedule the first target PRB;

[0170] Corresponding to the location being in the second area of ​​the indoor distribution scenario, resources for the first terminal to schedule the second target PRB;

[0171] Wherein, the first region is located at the center of the indoor distribution scene; the distance between the second region and the edge of the indoor distribution scene is less than a preset length;

[0172] The first BLER of the first target PRB is higher than the first BLER of the second target PRB; and / or, the first SINR of the first target PRB is lower than the first SINR of the second target PRB.

[0173] Here, the preset length can be set based on the actual scenario, such as 5 meters, 10 meters, etc.

[0174] In this way, the base station can schedule terminals based on statistics per time slot and per PRB of the terminal, and avoid PRBs with high BLER and / or low SINR, thereby improving transmission spectrum efficiency and realizing terminal scheduling at different locations.

[0175] The scheduling method provided in this invention is used for interference avoidance scheduling of indoor distribution stations in indoor-outdoor interference scenarios. Specifically, based on BLER statistics of PRBs, the indoor distribution station obtains the interference situation of different PRBs of the outdoor macro station on the indoor distribution station. According to the terminal feedback negative response (NACK) ratio, the scheduling PRB resources are selected. For example, PRB resources with greater interference are scheduled at the indoor distribution center and PRB resources with less interference are scheduled for users at the indoor distribution edge. This enables the indoor distribution station to actively avoid co-channel interference from outdoor macro stations, thereby improving the communication quality of the terminals.

[0176] Figure 2 A flowchart illustrating a scheduling method provided in an application embodiment of the present invention; as shown below. Figure 2 As shown, the scheduling method includes:

[0177] Step 201: The indoor distribution station dispatches downlink data to the indoor terminals;

[0178] Step 202: The indoor terminal feeds back the downlink data at the PRB level ACK / NACK level;

[0179] Step 203: The indoor distribution station calculates the BLER of all indoor terminals based on the PRB; calculates the BLER for a certain time window, and does not schedule PRBs with higher BLERs within a certain time period.

[0180] Thus, based on the ACK / NACK level of the PRB fed back by the indoor terminal, the indoor distribution station determines the channel interference level (i.e., the first BLER), and schedules resources according to the first BLER, avoiding PRBs with higher BLER and selecting PRBs with lower BLER, thereby improving data transmission efficiency.

[0181] Figure 3 This is a flowchart illustrating an overlap determination method provided in an embodiment of the present invention; as shown below. Figure 3 As shown, the method is applied to a second network device; the method includes:

[0182] Step 301: Receive feedback information sent by at least one second terminal serving the target cell;

[0183] Here, the feedback information can be used to reflect whether the service channel of the target cell is interfered with;

[0184] Step 302: Determine the second BLER of the target cell based on the feedback information sent by the at least one second terminal;

[0185] Step 303: Determine the overlap coverage result based on the second BLER.

[0186] In some embodiments, the second network device may be a base station, specifically an outdoor station, a macro station, etc.

[0187] The second terminal is the terminal served by the cell provided by the second network device, and can also be called an outdoor terminal. The second terminal can be a mobile phone, smartphone, laptop, digital radio receiver, personal digital assistant (PDA), tablet computer (PAD), portable multimedia player (PMP), wearable device (such as smart bracelet, smartwatch, etc.), navigation device, etc.

[0188] In some embodiments, receiving feedback information sent by at least one second terminal serving the target cell includes:

[0189] Receive feedback information for the scheduled data block sent by the second terminal; the feedback information includes: acknowledgment (ACK) and negative acknowledgment (NACK).

[0190] Specifically, the second network device (such as a macro base station) schedules downlink data to the outdoor terminal (i.e., the second terminal), and the second terminal sends feedback information, i.e., ACK / NACK, according to the scheduled data blocks.

[0191] In some embodiments, determining the second BLER of the target cell based on feedback information sent by the at least one second terminal includes:

[0192] Based on the feedback information sent by the at least one second terminal, determine the BLER of at least one beam direction of the target cell according to the beam direction;

[0193] By converging the BLERs of at least one beam direction, the BLER of the SSB is obtained, which serves as the second BLER.

[0194] Specifically, the macro station counts the number of ACK / NACK operations for all terminals in each beam direction (precoding matrix indicator (PMI) direction), and determines the BLER for that beam direction as BLER = number of ACK operations / (number of ACK operations + number of NACK operations) based on the number of ACK / NACK operations for all terminals in that beam direction.

[0195] Then, the beams are converged into an SSB according to the beam direction. Based on the BLER of the converged beam direction, the BLER of the SSB direction is obtained, which is the second BLER.

[0196] One possible method is to converge the beams of PMI services in the same direction as SSB into a beam in the direction of SSB.

[0197] In some embodiments, the BLER of converging the at least one beam to obtain the BLER of the SSB includes:

[0198] Determine the beam of PMI services that are in the same direction as SSB;

[0199] The BLER of the SSB is determined based on the BLER of the beam of the PMI service in the same direction as the SSB.

[0200] Here, the second Among them, B i This represents the BLER corresponding to the i-th beam, and N is the number of beams converged to obtain the SSB.

[0201] That is, to uniformly count the ACK / NACK of all beams within the convergence range, or to average the BLER of all service beams within the convergence range.

[0202] In some embodiments, determining the overlap coverage result based on the second BLER includes:

[0203] The target cell is determined to have overlapping coverage when it meets at least one of the following conditions:

[0204] The difference between the voltage level of the target cell and the voltage level of its neighboring cells at the same frequency is greater than a third threshold.

[0205] The reference signal received power of the target cell is greater than the fourth threshold.

[0206] The number of first beams exceeds the fifth threshold; the number of first beams is the number of beams in the target cell whose BLER exceeds the sixth threshold;

[0207] The number of second beams exceeds the seventh threshold; the number of second beams is the number of beams in the converged SSB whose corresponding BLER exceeds the eighth threshold.

[0208] Wherein, the third threshold can be -6dB; the fourth threshold can be -110dBm; the sixth threshold can be 10%; and the eighth threshold can be 10%.

[0209] The above is just one example. The third, fourth, fifth, sixth, seventh, and eighth thresholds can also be set based on actual application needs, and there are no specific limitations.

[0210] Specifically, overlapping coverage of a target cell is determined when the target cell meets the following conditions:

[0211] The voltage level difference between the target cell and the voltage level of a neighboring cell at the same frequency is greater than -6dB;

[0212] The RSRP of the target cell is greater than -110dBm;

[0213] The number of beams with a BLER greater than 10% exceeds N, or the proportion of beams with a BLER greater than 10% among all beams provided by the target cell is greater than alpha1.

[0214] The number of beams whose BLER is greater than 10% and which converge to the SSB exceeds M, or the proportion is greater than alpha2.

[0215] In practical applications, SINR can be used to determine the overlap coverage results, thereby improving the accuracy of the coverage results; based on this, in some embodiments, the method further includes:

[0216] Determine the SINR of at least one beam direction of the target cell;

[0217] By converging the SINRs of at least one beam direction, a second SINR of the synchronization signal block SSB is obtained;

[0218] The step of determining the overlap coverage result based on the second BLER also includes:

[0219] The target cell is determined to have overlapping coverage when it meets at least one of the following conditions:

[0220] The second SINR of the SSB is lower than the second SINR threshold;

[0221] The number of third beams exceeds the ninth threshold; the number of third beams is the number of beams in the converged SSB whose corresponding second SINR is lower than the second SINR threshold.

[0222] The method provided in this invention is used to calibrate overlapping coverage in macro base station scenarios. Here, the BLER of the beam reflects the interference situation in neighboring cells. Sample points are marked according to the BLER of the beam, or according to whether the BLER reported by the terminal with a certain time window is greater than 10% and / or whether the SINR is lower than a certain value, the overlapping coverage status of the sample points is marked, and the overlapping coverage decision of the sample points is calibrated.

[0223] The method provided in this embodiment of the invention is not based solely on RSRP received signal power. In the existing overlapping coverage decision identifier, the base station or network management adds an indicator that reflects the interference of the actual service channel, reflecting the interference of the neighboring cell service beam on the local service beam, so that the overlapping coverage can truly reflect the interference of the neighboring cell on the local area.

[0224] Figure 4 A flowchart illustrating an overlapping coverage determination method provided for an application embodiment of the present invention; Figure 4 As shown, the overlap determination method includes:

[0225] Step 401: The macro base station schedules downlink data to the outdoor terminal;

[0226] Step 402: The outdoor terminal sends back the downlink data at the PRB level ACK / NACK (i.e., sends feedback information);

[0227] Step 403: Calculate the BLER feedback of all terminals according to the beam direction (PMI direction);

[0228] Specifically, the macro base station counts the number of ACK / NACK operations for all terminals according to the beam direction (PMI direction) to determine the BLER of that beam. BLER = number of ACK operations / (number of ACK operations + number of NACK operations).

[0229] Step 404: Perform BLER statistical clustering based on the PMI direction to the SSB direction, and output BLER based on the SSB direction;

[0230] Specifically, macro stations converge the service beam directions into SSB directions, and the BLER of the SSB direction is determined based on the BLER of the converged beam directions; the BLER of the SSB direction reflects the level of interference in the service channel.

[0231] Step 405: Determine overlapping coverage based on BLER;

[0232] Specifically, for the target cell to be determined, overlapping coverage of the target cell is determined when the following conditions are met:

[0233] The voltage level difference between the target cell and the voltage level of a neighboring cell at the same frequency is greater than -6dB;

[0234] The RSRP of the target cell is greater than -110dBm;

[0235] The number of beams with a BLER greater than 10% exceeds N, or the proportion of beams with a BLER greater than 10% among all beams provided by the target cell is greater than alpha1.

[0236] The number of beams whose BLER is greater than 10% and which converge to the SSB exceeds M, or the proportion is greater than alpha2.

[0237] The method provided in this embodiment of the invention can, based on the overlapping coverage determination of related technologies, combine the BLER in the beam direction and the BLER in the SSB direction to perform overlapping coverage correction, so as to make the overlapping coverage determination more accurate.
