Background Art

[0002] The path loss of NR (New Radio) TDD (Time Division Duplexing) system is generally higher than that of LTE (Long Term Evolution) FDD (Frequency Division Duplexing) system, and the uplink coverage performance of TDD frame structure is generally worse than that of FDD frame structure. For example, the path loss of NR TDD system using 3.5GHz is 7-9dB higher than that of LTE FDD system using 1.8GHz on average; the uplink coverage performance of TDD frame structure using 2.5ms double period is 5.2dB worse than that of FDD frame structure.

[0003] Moreover, in the outdoor coverage indoor scenario, since the path loss and penetration loss of the 3.5GHz NR system are higher than those of the 1.8GHz LTE system, and the 3.5GHz NR system only has shallow uplink coverage indoors, its uplink deep coverage performance is worse than that of the 1.8GHz LTE system. Therefore, the uplink coverage capability of the NR system needs to be improved.

[0039] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present disclosure unless otherwise specifically stated.

[0040] At the same time, it should be understood that for the convenience of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship.

[0041] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0042] Technologies, methods, and apparatus known to ordinary technicians in the relevant field may not be discussed in detail, but where appropriate, such technologies, methods, and apparatus should be considered part of the authorization specification.

[0043] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0044] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0045] As mentioned above, since the number of repeated transmissions is configured based on continuous time slots, the effect of repeated transmission is poor.

[0046] For example, due to the frame structure of TDD, the terminal needs to avoid sending uplink information in the downlink time slot, so the number of times the time slot is repeated is limited (such as less than 8 or 16 times); moreover, only the first few time slots within the air interface delay (such as 16 time slots) can be used for repeated transmission, resulting in the inability to maximize the time diversity gain.

[0047] To solve the above technical problems, the network side configures the time slot actually used for repeated transmission on the terminal side to increase the maximum number of repeated transmissions or time diversity, thereby improving uplink coverage performance. For example, the technical solution of the present disclosure can be implemented through the following embodiments.

[0048] Figure 1 A flow chart showing some embodiments of the method for repeated transmission of uplink information of the present disclosure.

[0049] like Figure 1As shown, in step 110, all time slots existing in the air interface delay are determined according to the subcarrier spacing. For example, all time slots in the air interface delay that the voice data packet can tolerate can be determined.

[0050] In some embodiments, for voice services, during a talk spurt, a voice data packet to be transmitted is generated every 20 ms. Thus, each voice data packet needs to be transmitted within an air interface delay of 50 ms or 100 ms, that is, the tolerable air interface delay is 50 ms or 100 ms.

[0051] For example, the air interface delay that voice data packets can tolerate is 50ms or 100ms, and the subcarrier spacing is 30KHz. In this case, there are 100 time slots in the air interface delay of 50ms, and there are 200 time slots in the air interface delay of 100ms.

[0052] In step 120, indication information is sent to the terminal side, where the indication information is used to indicate available time slots in all time slots that can be used for repeated transmission of uplink information.

[0053] In some embodiments, the indication information is sent to the terminal side via high-layer signaling transmission. High-layer signaling includes RRC signaling and MAC signaling. For example, the network configures a repetitive transmission pattern (ie, bitmap information) and notifies the user terminal of the repetitive transmission pattern via high-layer signaling.

[0054] In some embodiments, bitmap information is sent to the terminal side as indication information. Each pixel information in the bitmap information identifies a time slot among all time slots, and the value of each pixel information identifies whether the corresponding time slot is an available time slot. For example, the size of the bitmap information is determined according to the number of all time slots, and each pixel information occupies 1 bit.

[0055] In some embodiments, the size of the bitmap information is determined according to the period of available time slots in all configured time slots, and the bitmap information is used to indicate each available time slot in a period. For example, the period of available time slots can be determined according to the frame structure.

[0056] In some embodiments, the subcarrier spacing is 30KHz, and the air interface delay requirement for voice data packets is 50ms. In this case, the air interface delay includes a total of 100 time slots. According to the frame structure, it can be determined that the period of the available time slots is 10 time slots, that is, the positions of the available time slots in every 10 time slots are the same.

[0057] For example, in every 10 time slots, the 1st, 2nd and 6th time slots are available time slots. In this case, the bitmap information may only include relevant information of available time slots in one cycle, that is, the size of the bitmap information matches the number of time slots in one cycle.

[0058] In this way, according to the periodicity of the available time slots, only the relevant information of the available time slots within one period needs to be transmitted to achieve repeated transmission, thereby reducing signaling overhead.

[0059] In step 130, repeated transmission of uplink information is triggered so that the terminal side repeatedly transmits the uplink information to be transmitted according to the indication information. For example, repeated transmission is triggered by physical layer signaling.

[0060] In some embodiments, after receiving high-layer signaling, the terminal stores the repeated transmission pattern therein; the base station triggers repeated transmission through physical layer signaling, such as PDCCH (Physical Downlink Control Channel); after receiving PDCCH, the terminal sends PUSCH according to the repeated transmission pattern.

[0061] In some embodiments, the indication information is used to indicate whether at least one of the uplink time slots, downlink time slots, special time slots, and flexible time slots in all time slots is an available time slot. Figure 2a The embodiment in generates bitmap information.

[0062] Figure 2a A schematic diagram showing some embodiments of the method for repeated transmission of uplink information of the present disclosure.

[0063] like Figure 2a As shown in the figure, the subcarrier spacing is 30KHz, and the air interface delay requirement for voice data packets is 50ms. In this case, the air interface delay includes a total of 100 time slots. The frame structure of the 2.5ms double period is DDDSUDDSUU, where D is the downlink time slot, U is the uplink time slot, and S is the special time slot.

[0064] In some embodiments, the network side notifies the terminal side whether all time slots (including downlink time slots, uplink time slots, special time slots, flexible time slots, etc.) in the air interface delay are available time slots through bitmap information. The size of the bitmap information is 100 bits, and 1 bit corresponds to 1 time slot.

[0065] For example, Figure 2a The middle part shows some pixels of the bitmap, and the time slots marked with shadows are available time slots. The available time slots include two downlink time slots and two uplink time slots.

[0066] In some embodiments, when the available time slot is a downlink time slot or a downlink symbol of a special time slot, the repeated transmission of the uplink information to be transmitted in the available time slot is cancelled by the terminal side. For example, when the available time slot is a downlink time slot (D in the figure), the repeated transmission of the uplink information to be transmitted in the downlink time slot is cancelled by the terminal side.

[0067] In some embodiments, the indication information is used to indicate available time slots in at least one of the uplink time slots and special time slots included in all time slots. In this way, only transmitting at least one of the available uplink time slots or special time slots can reduce signaling overhead. For example, Figure 2b The embodiment in generates bitmap information.

[0068] Figure 2b Schematic diagrams showing other embodiments of the method for repeated transmission of uplink information of the present disclosure.

[0069] like Figure 2b As shown in FIG. 1 , the subcarrier interval is 30KHz, and the air interface time requirement for voice data packets is 50ms. In this case, the air interface delay includes a total of 100 time slots.

[0070] In some embodiments, the network side notifies the terminal side whether the uplink time slot within the air interface delay is an available time slot through bitmap information. For example, there are 30 uplink time slots in 100 time slots, the size of the bitmap information is 30 bits, and 1 bit of pixel information indicates 1 time slot, which is used to identify whether the uplink time slot corresponding to each pixel information is an available time slot.

[0071] For example, the frame structure of a 2.5 ms double period is DDDSUDDSUU. Figure 2b The middle part shows some pixels of the bitmap, and the time slots marked with shadows are available time slots. The available time slots include 3 uplink time slots. The terminal sends PUSCH according to the uplink time slot indicated in the bitmap information.

[0072] In some embodiments, the 2.5ms single-cycle frame structure is DDDSU, and there are 20 uplink time slots in 100 time slots. The network side sends 20-bit bitmap information, and 1-bit pixel information indicates whether an uplink time slot is an available time slot; the terminal side sends PUSCH according to the time slot indicated in the bitmap information.

[0073] Figure 3 A block diagram showing some embodiments of the apparatus for repeatedly transmitting uplink information of the present disclosure.

[0074] like Figure 3 As shown, the device 3 for repeatedly transmitting uplink information includes a determining unit 31 , a sending unit 32 and a triggering unit 33 .

[0075] The determining unit 31 determines all time slots existing in the air interface delay according to the subcarrier spacing.

[0076] The sending unit 32 sends indication information to the terminal side. The indication information is used to indicate the available time slots in all time slots that can be used for repeated transmission of uplink information.

[0077] In some embodiments, the sending unit 32 sends bitmap information to the terminal side as indication information. Each pixel information in the bitmap information identifies a time slot among all time slots, and the value of each pixel information identifies whether the corresponding time slot is an available time slot.

[0078] For example, the size of the bitmap information is determined according to the number of all time slots, and each pixel information occupies 1 bit.

[0079] In some embodiments, the size of the bitmap information is determined according to the period in which available time slots appear in all configured time slots, and the bitmap information is used to indicate each available time slot in a period.

[0080] In some embodiments, the sending unit 33 sends the indication information to the terminal side via high-layer signaling transmission. For example, the high-layer signaling includes RRC signaling and MAC signaling.

[0081] The trigger unit 33 triggers repeated transmission of uplink information so that the terminal side repeatedly transmits the uplink information to be transmitted according to the indication information. For example, the trigger unit 33 triggers repeated transmission through physical layer signaling.

[0082] In some embodiments, the indication information is used to indicate an available time slot in at least one category of all time slots including uplink time slots, downlink time slots, special time slots, and flexible time slots; when the available time slot is a downlink time slot or a downlink symbol of a special time slot, the repeated transmission of the uplink information to be transmitted in the available time slot is canceled by the terminal side.

[0083] In some embodiments, the indication information is used to indicate available time slots in at least one category of uplink time slots and special time slots included in all time slots.
