Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a communication method, apparatus, device and storage medium based on channel quality. Background Art

[0002] In wireless communications, the Physical Uplink Shared Channel (PUSCH) serves as the core channel for terminal uplink data transmission. Its transmission reliability and resource efficiency directly affect the service experience, such as high-definition voice services, video upload services, and industrial control services. In addition, when data is transmitted through the PUSCH, time slot aggregation is usually involved, that is, data is sent repeatedly.

[0003] However, the existing PUSCH time slot aggregation level is usually statically configured by Radio Resource Control (RRC) signaling, and the PUSCH channel has a rapidly time-varying characteristic. When the channel is poor, if data is still retransmitted according to the low time slot aggregation level statically configured when the channel status is good, data transmission failure will occur, thereby affecting transmission reliability. When the channel status is good, if data is still retransmitted according to the high time slot aggregation level statically configured when the channel status is poor, it will cause a waste of time and frequency resources.

[0027] Example 1

[0028] Figure 1 A flow chart of a communication method based on channel quality is provided for the first embodiment of the present invention. This embodiment is applicable to the case of communicating with a terminal. The method can be performed by a communication device based on channel quality. The communication device based on channel quality can be implemented in the form of hardware and / or software, and the device can be integrated into an electronic device. Figure 1 As shown, the method includes:

[0029] Step S101: When it is detected that a terminal supporting physical uplink shared channel (PUSCH) timeslot aggregation has accessed the cell, a channel quality measurement is performed on the PUSCH to obtain a recommended timeslot aggregation level.

[0030] Optionally, when it is detected that a terminal supporting physical uplink shared channel PUSCH time slot aggregation has access to the cell, before performing channel quality measurement on the PUSCH to obtain the recommended time slot aggregation level, it also includes: establishing a cell in a designated area and setting the communication mode of the cell, wherein the communication mode includes frequency division duplex or time division duplex; configuring the mode constraints corresponding to the communication mode, wherein the mode constraints include the maximum allowed time slot aggregation level.

[0031] Specifically, in this embodiment, the base station will complete the basic configuration for the cell during the cell establishment phase, and mainly configure the communication mode within the cell and the mode constraints corresponding to the communication mode. The communication mode mainly includes frequency division duplex FDD mode or time division duplex TDD mode, wherein the frequency division duplex FDD mode refers to the bidirectional transmission of signals by allocating different frequencies, and the time division duplex TDD mode refers to the use of time division to achieve bidirectional communication. Different mode constraints are set for different communication modes, and the mode constraints mainly include the maximum allowed time slot aggregation level, and for the FDD mode, the maximum allowed time slot aggregation level included in the mode constraint is fixed, such as level 3, and the maximum allowed number of repetitions corresponding to level 3 is 8. Of course, this embodiment is only an example, and does not limit the maximum allowed number of repetitions configured for the FDD mode. For the TDD mode, the maximum allowed timeslot aggregation level included in the mode constraint changes dynamically, and the maximum allowed repetition number needs to be dynamically constrained according to the number of consecutive uplink timeslots. Therefore, in this embodiment, the maximum aggregation level is dynamically compressed for the frame structure resource limitation of the TDD system to avoid resource conflicts caused by high aggregation level configuration but insufficient timeslot resources, while at the same time, the FDD system releases all resource potential. The following table 1 shows the corresponding relationship between the range of consecutive downlink timeslots and the maximum allowed timeslot aggregation level:

[0032] Table 1

[0033]

[0034]

[0035] Specifically, when the base station accesses the terminal entering the cell, the terminal will send a capability reporting instruction to the base station, and the capability reporting instruction includes whether PUSCH time slot aggregation is supported. When it is determined that it is not supported, the field pusch-aggregationfactor in the physical layer scheduling instruction DCI 0-1 of the device is forced to be 00, that is, it is not sent repeatedly, thereby ensuring compatibility with old version terminals, wherein pusch-aggregationfactor is a new field in the physical layer scheduling instruction DCI 0-1. When it is determined that PUSCH time slot aggregation is supported, the subsequent adaptive process will be entered. In this embodiment, the time slot aggregation level is sent to the terminal by adding a dedicated field pusch-aggregationfactor in the physical layer scheduling instruction, so that compared with relying solely on RRC signaling, the data transmission requirements in low-latency business scenarios can be met.

[0036] Optionally, channel quality measurement is performed on the PUSCH to obtain a recommended time slot aggregation level, including: measuring the signal-to-noise ratio of a specified number of consecutive time slots of the PUSCH through the base station physical layer; calculating the average of the signal-to-noise ratio of a specified number of consecutive time slots using an exponential moving average algorithm through the base station link layer to obtain an average signal-to-noise ratio; and querying the time slot aggregation level list according to the average signal-to-noise ratio to obtain a recommended time slot aggregation level corresponding to the average signal-to-noise ratio, wherein the recommended time slot aggregation level includes a recommended number of PUSCH repetitions.

[0037] Specifically, in this embodiment, the PUSCH channel quality will be measured through the physical layer. Specifically, after the transmission of each PUSCH time slot is completed, the signal-to-noise ratio of the single resource block of the PUSCH channel is measured through the physical layer, i.e., L1, and the measurement value is reported in real time to the base station link layer, i.e., L2, through the CRC_indication signaling. The base station link layer accumulates the signal-to-noise ratio measurement values ​​of at least 5 consecutive time slots, and calculates the average signal-to-noise ratio using the exponential moving average algorithm. Since the calculation principle of the specified moving average algorithm is not the focus of this application, it will not be described in detail in this embodiment. Among them, in this embodiment, after obtaining the average signal-to-noise ratio, the base station link layer will query the time slot aggregation level list according to the average signal-to-noise ratio, and obtain the recommended time slot aggregation level corresponding to the average signal-to-noise ratio through the query. The following Table 2 shows an example of a time slot aggregation level list:

[0038] Table 2

[0039] Average SINR range Recommended aggregation level Corresponding PUSCH repetition times >20dB 0 No repetition [5dB,20dB] 1 n2 (repeat 2 times) [-3dB,5dB) 2 n4 (repeat 4 times) <-3dB 3 n8 (repeat 8 times)

[0040] Step S102: obtaining the mode constraint corresponding to the current communication mode, and determining the final time slot aggregation level according to the mode constraint and the recommended time slot aggregation level.

[0041] Optionally, the final time slot aggregation level is determined based on the mode constraints and the recommended time slot aggregation level, including: when the communication mode is determined to be time division duplex, the smaller level between the maximum allowed time slot aggregation level corresponding to time division duplex and the recommended time slot aggregation level is used as the final time slot aggregation level; when the communication mode is determined to be frequency division duplex, the recommended time slot aggregation level is directly used as the final time slot aggregation level.

[0042] Specifically, in this embodiment, after the recommended time slot aggregation level is obtained based on the channel quality measurement, it will be superimposed with the mode constraint conditions to determine the final time slot aggregation level. The superposition method used to obtain the final time slot aggregation level is: if it is a time division duplex TDD mode: the final time slot aggregation level = min ("recommended time slot aggregation level", "TDD maximum allowed time slot aggregation level"); if it is a frequency division duplex FDD mode: the final time slot aggregation level = "recommended time slot aggregation level". Of course, this embodiment is only an example for illustration, and does not limit the specific method for determining the final time slot aggregation level. As long as the determined final time slot aggregation level is related to the channel quality, it is within the scope of protection of this application.

[0043] For example, when the communication mode is determined to be time division duplex (TDD), if the recommended timeslot aggregation level determined based on the channel quality is level 1, and the maximum allowed timeslot aggregation level configured in the TDD mode constraints is level 2, then in order to ensure the reliability of data transmission while satisfying the constraints, the minimum level is taken, that is, the final timeslot aggregation level is determined to be level 1. When the communication mode is determined to be frequency division duplex (FDD), if the recommended timeslot aggregation level determined based on the channel quality is level 1, the final timeslot aggregation level is determined to be level 1. Of course, this embodiment is merely an example and does not limit the specific value of the final timeslot aggregation level.

[0044] Step S103: When it is determined that the PUSCH is in a non-data retransmission state, the final timeslot aggregation level is added as a new field to the physical layer scheduling instruction.

[0045] Optionally, the method also includes: when it is determined that the PUSCH is in a data retransmission state, waiting for the PUSCH to send the retransmitted data according to the historical time slot aggregation level; when it is determined that the retransmitted data has been sent and updated to a non-data retransmission state, adding the final time slot aggregation level as a new field to the physical layer scheduling instruction.

[0046] Specifically, when it is determined that the PUSCH is in a data retransmission state, the base station will activate the retransmission protection logic. The base station link layer will suspend the time slot aggregation level adjustment and maintain the historical time slot aggregation level until the retransmission is completed. When there is no retransmission, the final time slot aggregation level is added as a new field pusch-aggregationfactor to the physical layer scheduling instruction DCI 0-1 to achieve fast signaling control at the physical layer. Therefore, in this embodiment, during the retransmission process, the base station link layer freezes the pusch-aggregationfactor adjustment and maintains the historical aggregation level unchanged until the retransmission is completed, avoiding signaling conflicts between retransmission and aggregation adjustment.

[0047] Step S104: Generate an uplink scheduling message according to the physical layer scheduling instruction, and send the uplink scheduling message to the terminal, so that the terminal parses the uplink scheduling message to obtain the final time slot aggregation level, and time slot aggregates and sends the data on the PUSCH with reference to the final time slot aggregation level.

[0048] Optionally, an uplink scheduling message is generated according to the physical layer scheduling instruction, and the uplink scheduling message is sent to the terminal, including: generating an uplink scheduling message according to the scheduling instruction through the base station link layer, and sending the uplink scheduling message to the base station physical layer; sending the uplink scheduling message to the terminal based on the physical downlink control channel through the base station physical layer.

[0049] Specifically, in this embodiment, the base station link layer will generate an uplink scheduling message UL_DCI.request according to the physical layer scheduling instruction DCI 0-1 carrying the pusch-aggregationfactor, and send the uplink scheduling message down to the base station physical layer, and send the uplink scheduling message to the terminal based on the physical downlink control channel PDCCH through the base station physical layer. Among them, the terminal in this embodiment will perform blind detection on the PDCCH, and when UL_DCI.request is detected, it will parse it to obtain the final time slot aggregation level in the pusch-aggregationfactor field. When the terminal needs to send data to the base station, it will perform time slot aggregation and transmission according to the PUSCH repetition times corresponding to the final time slot aggregation level and the number of PUSCH repetitions. For example, when the terminal performs PUSCH repeated transmission according to the parsed aggregation level, specifically when the aggregation level is 0, a single transmission is performed; when the aggregation level is 1, it is repeated 2 times; when the aggregation level is 2, it is repeated 4 times; when the aggregation level is 3, it is repeated 8 times. Of course, this implementation is only an example and does not limit the specific value of the time slot repeated transmission.

[0050] This embodiment measures the PUSCH channel quality to obtain the recommended time slot aggregation level, and determines the final aggregation level in combination with the current mode constraints. The actual aggregation level determined based on the reference constraints and the actual channel conditions is sent to the terminal as a new field in the physical layer scheduling instruction, so that the terminal can dynamically aggregate and send data according to the channel transmission quality to ensure the reliability of data transmission.

[0051] Example 2

[0052] Figure 2 The flowchart of the communication method based on channel quality provided in the second embodiment of the present invention, based on the above embodiment, after sending the uplink scheduling message to the terminal, further includes: receiving the data sent by the terminal through PUSCH using time slot aggregation through the base station physical layer; calling the uplink demodulation message sent by the base station link layer, demodulating the information according to the uplink demodulation message, and feeding back the obtained demodulation result to the base station link layer. Figure 2 As shown, the method includes:

[0053] Step S201: When it is detected that a terminal supporting physical uplink shared channel (PUSCH) timeslot aggregation has accessed the cell, a channel quality measurement is performed on the PUSCH to obtain a recommended timeslot aggregation level.

[0054] Optionally, when it is detected that a terminal supporting physical uplink shared channel PUSCH time slot aggregation has access to the cell, before performing channel quality measurement on the PUSCH to obtain the recommended time slot aggregation level, it also includes: establishing a cell in a designated area and setting the communication mode of the cell, wherein the communication mode includes frequency division duplex or time division duplex; configuring the mode constraints corresponding to the communication mode, wherein the mode constraints include the maximum allowed time slot aggregation level.

[0055] Optionally, channel quality measurement is performed on the PUSCH to obtain a recommended time slot aggregation level, including: measuring the signal-to-noise ratio of a specified number of consecutive time slots of the PUSCH through the base station physical layer; calculating the average of the signal-to-noise ratio of a specified number of consecutive time slots using an exponential moving average algorithm through the base station link layer to obtain an average signal-to-noise ratio; and querying the time slot aggregation level list according to the average signal-to-noise ratio to obtain a recommended time slot aggregation level corresponding to the average signal-to-noise ratio, wherein the recommended time slot aggregation level includes a recommended number of PUSCH repetitions.

[0056] Step S202: Obtain the mode constraint corresponding to the current communication mode, and determine the final time slot aggregation level according to the mode constraint and the recommended time slot aggregation level.

[0057] Optionally, the final time slot aggregation level is determined based on the mode constraints and the recommended time slot aggregation level, including: when the communication mode is determined to be time division duplex, the smaller level between the maximum allowed time slot aggregation level corresponding to time division duplex and the recommended time slot aggregation level is used as the final time slot aggregation level; when the communication mode is determined to be frequency division duplex, the recommended time slot aggregation level is directly used as the final time slot aggregation level.

[0058] Step S203: When it is determined that the PUSCH is in a non-data retransmission state, the final timeslot aggregation level is added as a new field to the physical layer scheduling instruction.

[0059] Optionally, the method also includes: when it is determined that the PUSCH is in a data retransmission state, waiting for the PUSCH to send the retransmitted data according to the historical time slot aggregation level; when it is determined that the retransmitted data has been sent and updated to a non-data retransmission state, adding the final time slot aggregation level as a new field to the physical layer scheduling instruction.

[0060] Step S204: Generate an uplink scheduling message according to the physical layer scheduling instruction, and send the uplink scheduling message to the terminal, so that the terminal parses the uplink scheduling message to obtain the final time slot aggregation level, and time slot aggregates and sends the data on the PUSCH with reference to the final time slot aggregation level.

[0061] Optionally, an uplink scheduling message is generated according to the physical layer scheduling instruction, and the uplink scheduling message is sent to the terminal, including: generating an uplink scheduling message according to the scheduling instruction through the base station link layer, and sending the uplink scheduling message to the base station physical layer; sending the uplink scheduling message to the terminal based on the physical downlink control channel through the base station physical layer.

[0062] Step S205: Receive data sent by the terminal through PUSCH using time slot aggregation through the base station physical layer, retrieve the uplink demodulation message sent by the base station link layer, demodulate the information according to the uplink demodulation message, and feed back the obtained demodulation result to the base station link layer.

[0063] Specifically, in this embodiment, the base station link layer L2 sends an uplink scheduling message UL_DCI.request to the base station physical layer L1, and also sends an uplink demodulation message UL_TTI.request to the base station physical layer L1. The uplink demodulation message includes PUSCH demodulation parameters, where the demodulation parameters may specifically include time-frequency resources or modulation and coding methods, etc. The specific type of PUSCH demodulation parameters is not limited in this embodiment. As long as they are related to the demodulated data, they are within the protection scope of this application. The base station physical layer will cache the received uplink demodulation message. Therefore, when the base station receives the data sent by the terminal through PUSCH using time slot aggregation through the base station physical layer L1, it will retrieve the uplink demodulation message previously sent by the base station link layer, demodulate the information according to the uplink demodulation message to obtain the demodulation result, and feed back the demodulation result to the base station link layer L2 through CRC_indication to complete a closed loop.

[0064] This embodiment measures the PUSCH channel quality to obtain the recommended time slot aggregation level, and determines the final aggregation level in combination with the current mode constraints. The actual aggregation level determined based on the reference constraints and the actual channel conditions is sent to the terminal as a new field in the physical layer scheduling instruction, so that the terminal can dynamically aggregate and send data according to the channel transmission quality to ensure the reliability of data transmission.

[0073] Optionally, the apparatus further comprises a recommended time slot aggregation level obtaining module configured to measure a signal-to-noise ratio of a continuous specified number of time slots of the PUSCH by a physical layer of the base station.

[0074] The signal-to-noise ratio of the continuous specified number of time slots is calculated by an exponential moving average algorithm of a link layer of the base station to obtain an average signal-to-noise ratio.

[0075] The time slot aggregation level list is queried according to the average signal-to-noise ratio to obtain a recommended time slot aggregation level corresponding to the average signal-to-noise ratio, wherein the recommended time slot aggregation level comprises a PUSCH recommended repetition number.
