Description

Technical Field

[0001] Embodiments of the present disclosure relate to the field of wireless communication, but are not limited to the field of wireless communication, and in particular, to a method and apparatus for determining data processing duration, a communication device, and a storage medium. Background Art

[0002] In 5G communication, a base station realizes scheduling of uplink and downlink resources of terminal communication by sending downlink control information (DCI) carried by a physical downlink control channel (PDCCH) to a terminal. The terminal listens to the PDCCH to parse the DCI belonging to itself, and transmits data on the scheduled uplink and downlink resources.

[0003] When the 5G New Radio (NR) protocol defines the monitoring complexity of a physical downlink shared channel (PDSCH) based on a single time slot (slot), it determines the time for demodulating the data transmitted on the PDSCH and the time for preparing the data transmitted on a physical uplink shared channel (PUSCH). However, for a larger subcarrier spacing (SCS) in high-frequency communication, the duration of a single time slot is too short. If a time unit including multiple time slots is used to define the PDCCH monitoring complexity, it is difficult to ensure that the terminal has sufficient duration to demodulate the required DCI.

[0078] Please refer to Figure 1 , which shows a schematic structural diagram of a wireless communication system provided by the embodiments of the present disclosure. As Figure 1 shown, the wireless communication system is a communication system based on cellular mobile communication technology. The wireless communication system may include: a plurality of terminals 11 and a plurality of base stations 12.

The terminal 11 may communicate with one or more core networks via a radio access network (RAN). The terminal 11 may be an Internet of Things (IoT) terminal, such as a sensor device, a mobile phone (or referred to as a "cellular" phone), and a computer with an IoT terminal. For example, it may be a fixed, portable, pocket-sized, handheld, computer-integrated, or vehicle-mounted device.

For example, the network management device 13 may be a Mobility Management Entity (MME) in an Evolved Packet Core (EPC).

[0086] As Figure 2 shown, the embodiments of the present disclosure provide a method for determining the data processing duration, which is applied to a base station and includes:

[0087] Step S101, obtain a time increment required for performing preset data processing according to the PDCCH monitoring complexity, where the preset data processing is: demodulation of a PDSCH transmission scheduled by DCI monitored on the PDCCH, or preparation for a PUSCH transmission.

[0088] During the communication between the UE and the base station, the base station sends downlink control information through the physical layer channel PDCCH to provide various control information to the terminal, including: Hybrid Automatic Repeat Request (HARQ), power control commands, identification of data transmission formats, and power control, etc. When the base station sends DCI, it will send multiple control information to multiple users at the same time. Therefore, the UE needs to use the blind detection method to identify the DCI it needs.

[0089] The above-mentioned PDCCH monitoring complexity, that is, the ability of the UE's own system to blindly detect PDCCH monitoring events, includes the maximum number of blind detections in a single time slot and the number of the maximum non-overlapping CCEs (Control Channel Elements). Based on the PDCCH monitoring complexity, the duration required for the UE to demodulate DCI can be determined, and further the duration required for the above-mentioned preset data processing: the demodulation of PDSCH transmission and the preparation of PUSCH transmission can be determined.

[0090] In the embodiments of the present disclosure, downlink data is carried on the PDSCH, and uplink data is carried on the PUSCH. The base station schedules the transmission on the PDSCH and / or the transmission on the PUSCH through DCI. DCI is carried and transmitted on the PDCCH, and the resources on the PDCCH are also the control information resource set (CORESET).

[0091] In the 5G NR protocol, the minimum PDSCH demodulation time (the shortest interval from the end position of the PDSCH to the start position of the HARQ response message) N1 value and the PUSCH preparation duration (from the end position of the PDCCH where the scheduling DCI is located to the start position of the PUSCH) N2 value under different SCSs (15 / 30 / 60 / 120KHz) are defined.

[0092] For example, in a case of UE capabilities and network configurations, the N1 value is shown in Table 1 below (subcarriers 0 / 1 / 2 / 3 represent 15 / 30 / 60 / 120kHz respectively):

[0093] Sub - carrier <![CDATA[Number of N1 symbols]]> 0 8 1 10 2 17 3 20

[0094] Table 1

[0095] For example, in a case of UE capabilities and network configurations, the N2 value is shown in Table 2 below:

[0096] Sub - carrier <![CDATA[Number of N2 symbols]]> 0 10 1 12 2 23 3 36

[0097] Table 2

[0098] However, the PDSCH demodulation duration and the PUSCH preparation duration in the case of larger SCSs (such as 240 / 480 / 960KHz, etc.) have not been determined yet.

[0099] In the 5G NR protocol, the blind detection capability of the UE on a single carrier is specified. According to different SCSs, the blind detection capability of the UE within a time slot is specified, mainly including the maximum number of blind detections within each time slot, as shown in Table 3, and the maximum number of non-overlapping CCEs within each time slot, as shown in Table 4. (In the table, μ = 0 represents SCS of 15KHz, μ = 1 represents SCS of 30KHz, μ = 2 represents SCS of 60KHz, and so on)

[0100]

[0101] Table 3

[0102]

[0103] Table 4

[0104] Currently, the NR protocol is only used in frequencies below 52.6GHZ, and the optional SCSs are 15KHz / 30KHz / 60KHz / 120KHz. In the case of a 15KHz subcarrier bandwidth, the duration of one time slot is 1ms. In the case of a 30KHz subcarrier bandwidth, the duration is 0.5ms. In the case of a 60KHz subcarrier bandwidth, the duration is 0.25ms, and so on. It can be seen that the larger the SCS, the shorter the duration of one time slot. Therefore, multiple time slots can be used to define the PDCCH monitoring complexity.

[0105] However, in the case where the time unit for defining the PDCCH monitoring complexity is multiple time slots, it is possible that within a PDCCH monitoring period, a large number of DCIs are concentrated and sent in a certain time slot. This concentrated transmission method may affect the duration of the terminal demodulating the DCI. Considering the situation where the DCI is concentrated and sent on 2 or 3 symbols in a certain time slot, when the average DCI detection complexity is the same within the same unit time, the larger the time unit, the longer the time required for the terminal to ensure that all DCIs can be demodulated.

[0106] Therefore, in the embodiments of the present disclosure, the time increment required for demodulating the above-mentioned PDSCH transmission or preparing for the PUSCH transmission can be determined according to the PDCCH monitoring complexity, so as to provide sufficient duration compared to the duration defined under a single time slot, and further be able to meet the capabilities of the terminal to demodulate all DCIs.

[0107] In some embodiments, obtaining the time increment required for performing preset data processing determined according to the PDCCH monitoring complexity includes:

[0108] Determining the time increment required for performing preset data processing according to the PDCCH monitoring complexity;

[0109] Or

[0110] Receive the time increment required for preset data processing determined according to the PDCCH monitoring complexity reported by the user equipment UE.

[0111] In the embodiments of the present disclosure, the base station obtains the above time increment from the terminal, or the base station itself can determine the time increment. That is, the method for determining the data processing duration can be executed by the base station or the UE performing wireless communication. For example, the base station determines the above time increment by obtaining the PDCCH monitoring complexity of the UE or by protocol. Furthermore, the duration required for the above preset data processing can be determined through the time increment and the known reference duration, and data scheduling is performed according to this duration.

[0112] In some embodiments, as Figure 3 shown, the method further includes:

[0113] Step S201, receive the processing capability information of the UE;

[0114] The determining the time increment required for preset data processing according to the PDCCH monitoring complexity includes:

[0115] Step S202, determine the time increment required for preset data processing according to the PDCCH monitoring complexity and the processing capability of the UE indicated by the processing capability information.

[0116] In the embodiments of the present disclosure, the base station can obtain the PDCCH monitoring complexity supported by the terminal and the processing capability of the UE through the protocol, or directly receive the PDCCH monitoring complexity supported by the UE and the processing capability of the UE by the UE reporting the processing capability. The processing capability of the UE includes the processing speed of the UE for demodulating DCI, the decoding capability of downlink data, and the encoding capability of uplink data, etc.

[0117] There are differences in the processing capabilities of different UEs. Therefore, the durations required for demodulating DCI, demodulating the corresponding PDSCH transmission, and preparing the PUSCH transmission are different. Therefore, in the embodiments of the present disclosure, the above time increment is determined through the above PDCCH monitoring complexity and the processing capability of the UE.

[0118] In this way, it is convenient for the terminal to complete the demodulation of DCI and the above-mentioned predetermined data processing within a sufficient long period.

[0119] In some embodiments, the PDCCH monitoring complexity is associated with the time unit defining the PDCCH monitoring complexity;

[0120] The determining the time increment required for preset data processing according to the PDCCH monitoring complexity includes:

[0121] Determine the time increment required for performing preset data processing according to the time unit defining the PDCCH monitoring complexity.

[0122] In the embodiments of the present disclosure, considering that in scenarios such as high-frequency communication, the time of a single time slot is short, and not every time slot can necessarily be used to send DCI. Therefore, the corresponding PDCCH monitoring complexity can be defined within the time units of multiple time slots.

[0123] Here, the PDCCH monitoring complexity is reflected by the time unit, and the PDCCH monitoring complexity supported by the terminal is: the maximum number of blind detections and the number of maximum non-overlapping CCEs supported within the time unit, etc. For example, if the time unit is 4 time slots, the PDCCH monitoring complexity is the maximum number of blind detections and the number of maximum non-overlapping CCEs supported by the terminal on every 4 time slots. At this time, the maximum number of blind detections and the number of maximum non-overlapping CCEs on average for each time slot are 1 / 4 of the above-mentioned monitoring complexity. But in fact, DCI may be received in each time slot among every 4 time slots, or DCI may only be received concentratedly in some time slots, that is, the terminal only performs parsing after receiving DCI. Therefore, the above-mentioned PDCCH monitoring complexity is defined using a time unit including multiple time slots.

[0124] Exemplarily, at around 60 GHz in the high-frequency band, in order to cope with phase noise, a relatively large subcarrier bandwidth can be selected, such as 960 KHz. A larger SCS corresponds to a shorter time slot duration. In the case of 960 KHz, the duration of a time slot is 0.015625 ms, that is, 1 / 64 ms. Since in a high-frequency communication system, the duration of a time slot is short, there may be the following two ways to define the PDCCH monitoring complexity:

[0125] Method 1: Still define the PDCCH monitoring complexity with each time slot as the time unit;

[0126] Method 2: Define the maximum PDCCH monitoring complexity of the terminal according to the time unit in units of multiple time slots. For example, in the case of SCS = 480 KHz, define the PDCCH monitoring complexity supported by the terminal as:

[0127] Within every 4 time slots, the maximum number of blind detections supported is 30;

[0128] Within every 4 time slots, the number of maximum non-overlapping CCEs supported is 40.

[0129] The advantage of taking multiple time slots as one time unit is that the terminal does not need to unnecessarily disperse its blind detection ability in each time slot. At the same time, the base station can configure a PDCCH monitoring period with a longer cycle, enabling the terminal to not monitor the PDCCH in most time slots and only receive the PDCCH concentratedly in certain time slots, which is thus beneficial to the terminal's energy saving.

[0130] Based on the embodiments of the present disclosure, on the basis of the maximum number of blind detections per average time slot and the duration corresponding to the maximum number of non-overlapping CCEs for the above-mentioned predetermined data processing for the PDCCH monitoring complexity, the time increment required for the UE to perform the above-mentioned preset processing when all DCIs are transmitted concentratedly within the time unit is also considered, thereby enabling the determination of the demodulation duration of the PDSCH transmission and the preparation of the PUSCH transmission to meet the UE's demodulation ability.

[0131] In some embodiments, the method further includes:

[0132] Determine the time unit defining the PDCCH monitoring complexity according to the SCS applied by the UE.

[0133] In the embodiments of the present disclosure, since the monitoring complexity of the PDCCH of the terminal corresponding to different SCSs is different in a single time slot. Therefore, in high-frequency communication, the time units defining the PDCCH monitoring complexity are also different under different SCSs. For example, when the SCS frequency is low, the PDCCH monitoring complexity is defined in a single time slot, while when the SCS is within different frequency band ranges, the time units for defining the above-mentioned PDCCH monitoring complexity are determined respectively in different numbers of multiple time slots.

[0134] In this way, the time unit defining the PDCCH monitoring complexity is more flexible, facilitating meeting the communication requirements of the UE under different SCSs.

[0135] In some embodiments, the time increment is: the duration increment relative to the duration required for preset data processing when the time unit defining the PDCCH monitoring complexity is 1 time slot.

[0136] In the embodiments of the present disclosure, it is considered that the terminal itself usually performs DCI demodulation and demodulates the PDSCH transmission or prepares for the PUSCH transmission in units of one time slot. On this basis, if the PDCCH monitoring complexity is defined by a time unit of multiple time slots, multiple DCIs may be transmitted concentratedly in the same time slot, thus increasing the duration of the terminal's demodulation.

[0137] Therefore, in the embodiments of the present disclosure, the above duration increment is defined by the duration required for performing preset data processing when the time unit defining the PDCCH monitoring complexity is 1 time slot. In this way, the actual duration required for performing preset data processing is the processing duration corresponding to the original definition with 1 time slot as the time unit plus the above duration increment. For example, when the time unit defining the PDCCH monitoring complexity is 1 time slot, the duration required for performing preset data processing is N transmission symbols, and the duration increment is O transmission symbols, then the duration required for performing the above preset data processing when the PDCCH monitoring complexity is defined on a time unit including multiple time slots can be determined as N + O.

[0138] In this way, by determining the duration increment, it is convenient to be compatible with the single time slot definition of the PDCCH monitoring complexity corresponding to the existing protocol, so that the UE has sufficient duration to complete the above preset data processing.

[0139] As Figure 4 shown, the embodiments of the present disclosure provide a method for determining the data processing duration, which is applied to a terminal and includes:

[0140] Step S301: Determine the time increment required for performing preset data processing according to the physical downlink control channel (PDCCH) monitoring complexity, where the preset data processing is: demodulation of the physical downlink shared channel (PDSCH) transmitted by the downlink control information (DCI) monitored on the PDCCH, or preparation for the transmission of the physical uplink shared channel (PUSCH).

[0141] In this embodiment, the entity executing the above method for determining the time increment is the terminal, and the terminal reports the determined time increment to the base station communicatively connected to the terminal.

[0142] Here, the terminal can be any UE with wireless communication functions, such as a mobile phone, a laptop computer, a wireless wearable device, and various other communication devices. In the embodiments of the present disclosure, the terminal can determine the above time increment based on the PDCCH monitoring complexity and communication capabilities supported by itself.

[0143] In some embodiments, the method further includes:

[0144] Reporting the time increment to the base station.

[0145] In another embodiment, the base station can also directly determine the above time increment through the protocol.

[0146] In some embodiments, the method for determining the data processing duration provided by the embodiments of the present disclosure includes:

[0147] Reporting the processing capability information of the terminal to the base station.

[0148] The processing capabilities of the terminal, including the processing speed of the terminal for demodulating DCI, the decoding ability for downlink data, and the encoding ability for uplink data, etc.

[0149] In some embodiments, the method for determining the data processing duration provided by the embodiments of the present disclosure is applied to a UE and includes:

[0150] Report the processing capability information of the UE, where the processing capability information is used for the base station to determine the time increment required for performing preset data processing in combination with the PDCCH complexity, and the preset data processing is: the demodulation of the physical downlink shared channel PDSCH transmission scheduled by the downlink control information DCI monitored on the PDCCH, or the preparation for the physical uplink shared channel PUSCH transmission.

[0151] There are differences in the processing capabilities of different terminals. Therefore, the durations required for demodulating DCI and the demodulated response PDSCH transmission and preparing for the PUSCH transmission are different. Therefore, in the embodiments of the present disclosure, the terminal reports its own processing capabilities to the base station, and the base station then determines the above time increment based on the above PDCCH monitoring complexity and the processing capabilities of the terminal.

[0152] In some embodiments, the PDCCH monitoring complexity is associated with the time unit defining the PDCCH monitoring complexity;

[0153] Determining the time increment required for performing preset data processing according to the PDCCH monitoring complexity includes:

[0154] Determine the time increment required for performing preset data processing according to the time unit defining the PDCCH monitoring complexity.

[0155] In the embodiments of the present disclosure, considering scenarios such as high-frequency communication, the time of a single time slot is short, and it is not necessarily possible to use each time slot for transmitting DCI. Therefore, the corresponding PDCCH monitoring complexity can be defined within the time units of multiple time slots.

[0156] Here, the PDCCH monitoring complexity is reflected by a time unit, and the PDCCH monitoring complexity supported by the terminal is: the maximum number of blind detections supported within the time unit, the number of maximum non-overlapping CCEs, etc. For example, if the time unit is 4 time slots, the PDCCH monitoring complexity is the maximum number of blind detections supported by the terminal on every 4 time slots and the number of maximum non-overlapping CCEs. At this time, the maximum number of blind detections and the number of maximum non-overlapping CCEs on each time slot on average are 1 / 4 of the above-mentioned monitoring complexity. However, in fact, DCI may be received on each time slot in every 4 time slots, or DCI may only be received concentrated in some time slots, that is, the terminal only performs parsing after receiving DCI. Therefore, a time unit including multiple time slots is used to define the above-mentioned PDCCH monitoring complexity.

[0157] In some embodiments, the method further includes:

[0158] Determine the time unit for defining the PDCCH monitoring complexity according to the SCS applied by the terminal.

[0159] In the embodiments of the present disclosure, since the monitoring complexity of the PDCCH of the terminal corresponding to different SCSs is different on a single time slot. Therefore, in high-frequency communication, the time units for defining the PDCCH monitoring complexity under different SCSs are also different. For example, when the SCS frequency is low, the PDCCH monitoring complexity is defined on a single time slot, while when the SCS is within different frequency band ranges, the time units for determining the PDCCH monitoring complexity are corresponding to different numbers of multiple time slots respectively.

[0160] In this way, the time unit for defining the PDCCH monitoring complexity is more flexible, which is convenient for meeting the communication requirements of the UE under different SCSs.

[0161] In some embodiments, the time increment is: the time increment relative to the duration required for preset data processing when the time unit for defining the PDCCH monitoring complexity is 1 time slot.

[0162] In the embodiments of the present disclosure, considering that the terminal usually performs DCI demodulation and demodulation of PDSCH transmission or preparation for PUSCH transmission in units of one time slot. On this basis, if the PDCCH monitoring complexity is defined by a time unit of multiple time slots, multiple DCIs may be sent concentrated in the same time slot, thus increasing the duration of the terminal for demodulation.

[0163] Therefore, in the embodiments of the present disclosure, when the time unit defining the PDCCH monitoring complexity is one time slot, the above-mentioned duration increment is defined by the duration required for performing preset data processing. In this way, the actual duration required for performing the preset data processing is the processing duration corresponding to one time slot defined originally plus the above-mentioned duration increment. For example, when the time unit defining the PDCCH monitoring complexity is one time slot, the duration required for performing the preset data processing is N transmission symbols, and the duration increment is O transmission symbols. Then, when the PDCCH monitoring complexity is defined on a time unit including multiple time slots, the duration required for performing the above-mentioned preset data processing can be determined as N + O.

[0164] In this way, by determining the duration increment, it is convenient to be compatible with the single time slot definition of the PDCCH monitoring complexity corresponding to the existing protocol, so that the UE has sufficient duration to complete the above-mentioned preset data processing.

[0165] In the embodiments of the present disclosure, a method for determining the data processing duration is provided, including:

[0166] Determine the time increment required for performing preset data processing according to the monitoring complexity of the PDCCH, where the preset data processing is: demodulation of the PDSCH transmission scheduled by the DCI monitored on the PDCCH, or preparation for the PUSCH transmission.

[0167] Here, the method for determining the data processing duration can be executed by a base station or a UE performing wireless communication. For example, the base station determines the above-mentioned time increment by obtaining the PDCCH monitoring complexity of the UE or by determining the PDCCH monitoring complexity through the protocol. Furthermore, the duration required for performing the above-mentioned preset data processing can be determined through the time increment and the known reference duration, and data scheduling is performed according to this duration.

[0168] In some embodiments, the monitoring complexity of the PDCCH is associated with the time unit defining the PDCCH monitoring complexity;

[0169] The determining the time increment required for performing preset data processing according to the monitoring complexity of the PDCCH includes:

[0170] Determine the time increment required for performing preset data processing according to the time unit defining the PDCCH monitoring complexity.

[0171] In some embodiments, the method further includes:

[0172] Determine the time unit defining the PDCCH monitoring complexity according to the SCS applied by the UE.

[0173] In some embodiments, determining the time increment required for performing preset data processing according to the monitoring complexity of PDCCH includes:

[0174] Determining the time increment required for performing preset data processing according to the monitoring complexity of PDCCH and the processing capability of the UE.

[0175] In some embodiments, the method is applied to a terminal; the method further includes:

[0176] Reporting the determined time increment.

[0177] In some embodiments, the time increment is: the duration increment relative to the duration required for performing preset data processing when the time unit defining the monitoring complexity of PDCCH is 1 time slot.

[0178] The embodiments of the present disclosure also provide the following examples:

[0179] In the protocol, directly define the optional time units for defining the monitoring complexity of PDCCH under different SCSs, and define the time increment for PDSCH demodulation and the time increment for PUSCH processing under this time unit. This time increment is the increment relative to the PDSCH demodulation duration or the PUSCH processing duration when the PDCCH monitoring complexity is defined with a single time slot as the time unit.

[0180] For example, the protocol defines that under 480 khz SCS, the optional time unit for the monitoring complexity of PDCCH is 4 time slots, the time increment for PDSCH demodulation under this time unit is O1 symbols; the time increment for PUSCH processing is O2 symbols. In addition, the protocol defines that the PDSCH demodulation duration when the PDCCH monitoring complexity is defined with a single time slot as the time unit is N1 symbols; the PUSCH processing duration is N2 symbols. Then under 480 khz SCS, when the time unit of the PDCCH monitoring complexity is 4 time slots, the PDSCH demodulation duration is determined by N1 and O1, for example, the sum of N1 and O1; the PUSCH processing duration is determined by N2 and O2 symbols, for example, the sum of N2 and O2.

[0181] In addition, the terminal can report its blind detection capability in units of a certain time unit to the base station, and also report the corresponding incremental duration. This time increment is the increment relative to the PDSCH demodulation duration or the PUSCH processing duration when the PDCCH monitoring complexity is defined with a single time slot as the time unit in the protocol.

[0182] For example, the terminal reports to the base station that, under 480 khz SCS, the time unit defining the PDCCH monitoring capability of this terminal is 4 time slots, and reports that the time increment for PDSCH demodulation under this time unit is O1 symbols; the time increment for PUSCH processing is O2 symbols. Additionally, in the protocol, the duration of PDSCH demodulation defining the PDCCH monitoring complexity with a single time slot as the time unit is N1 symbols; the duration of PUSCH processing is N2 symbols. Then, under 480 khz SCS, when the time unit of the PDCCH monitoring complexity is 4 time slots, the duration of PDSCH demodulation is determined by N1 and O1 symbols, such as the sum of N1 and O1; the duration of PUSCH processing is determined by N2 and O2 symbols, such as the sum of N2 and O2.
