For example, the path loss of the NR TDD system adopting 3.5GHz is averagely 7-9 dB higher than that of the LTE FDD system adopting 1.8 GHz; the uplink coverage performance of the TDD frame structure with 2.5ms double periods is 5.2dB worse than that of the FDD frame structure.
Moreover, in an outdoor coverage indoor scenario, since the path loss and the 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 indoor uplink shallow coverage capability, the uplink deep coverage performance is worse than that of the 1.8GHz LTE system.

Detailed Description
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 the components and steps, the numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present disclosure unless specifically stated otherwise.
Meanwhile, it should be understood that the sizes of the respective portions shown in the drawings are not drawn in an actual proportional relationship for the convenience of description.
The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the disclosure, its application, or uses.
Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate.
In all examples shown and discussed herein, any particular value should be construed as exemplary only and not as limiting. Thus, other examples of the exemplary embodiments may have different values.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
As described above, since the number of times of the repeated transmission is configured based on the consecutive slots, the repeated transmission is not effective.
For example, due to the frame structure of TDD, the terminal needs to avoid sending uplink information in the downlink timeslot, so the number of times of timeslot repeat transmission is limited (e.g. less than 8 or 16 times); moreover, only the first few time slots (e.g., 16 time slots) in the air interface delay can be used for repeated transmission, so that the time diversity gain cannot be maximized.
In view of the above technical problems, the network side configures a time slot actually used for the repeated transmission by the terminal side to improve the maximum repeated transmission times or time diversity, thereby improving the uplink coverage performance. For example, the technical solutions of the present disclosure can be realized by the following embodiments.
Fig. 1 shows a flow chart of some embodiments of the disclosed method for repeated transmission of uplink information.
As shown in fig. 1, in step 110, all timeslots existing within the air interface delay are determined according to the subcarrier spacing. For example, all timeslots within the air interface delay that can be tolerated by the voice data packet may be determined.
In some embodiments, for voice traffic, a voice packet to be transmitted is generated every 20ms during a talk spurt. Thus, each voice data packet needs to be transmitted within 50ms or 100ms of air interface delay, that is, the tolerable air interface delay is 50ms or 100 ms.
For example, the delay of the air interface which can be tolerated by the voice data packet is 50ms or 100ms, and the subcarrier interval is 30 KHz. In this case, the 50ms air interface delay coexists in 100 slots, and the 100ms air interface delay coexists in 200 slots.
In step 120, indication information is sent to the terminal side, where the indication information is used to indicate an available timeslot that can be used for repeatedly transmitting uplink information in all timeslots.
In some embodiments, the indication information is sent to the terminal side by a higher layer signaling transmission. The high layer signaling comprises RRC signaling and MAC signaling. For example, the network configures a repetitive transmission pattern (i.e., bitmap information) and informs the user terminal of the repetitive transmission pattern through higher layer signaling.
In some embodiments, bitmap information is sent to the terminal side as the indication information. Each pixel information in the bitmap information identifies one of 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 the slots, and each pixel information occupies 1 bit.
In some embodiments, the size of the bitmap information is determined according to a period in which available time slots appear in all configured time slots, and the bitmap information is used for indicating each available time slot in one period. For example, the period in which the available slots occur may be determined according to the frame structure.
In some embodiments, the subcarrier spacing is 30KHz and the null delay requirement for a voice packet is 50 ms. In this case, the air interface delay includes 100 slots in total. According to the frame structure, it can be determined that the available time slots occur with a period of 10 time slots, i.e., the available time slots occur at the same position in every 10 time slots.
For example, in each 10 slots, the 1 st, 2 nd and 6 th slots are available slots. In this case, the bitmap information may contain only information about the available time slots in 1 cycle, i.e. the size of the bitmap information matches the number of time slots in 1 cycle.
Therefore, according to the periodicity of the available time slots, the repeated transmission can be realized by only transmitting the relevant information of the available time slots in 1 period, thereby reducing the signaling overhead.
In step 130, the repeated transmission of the uplink information is triggered, so that the terminal side repeatedly transmits the uplink information to be transmitted according to the indication information. For example, the repeat transmission is triggered by physical layer signaling.
In some embodiments, after receiving the higher layer signaling, the terminal stores the repeated transmission pattern therein; the base station triggers repeated transmission through physical layer signaling, such as a Physical Downlink Control Channel (PDCCH); and after receiving the PDCCH, the terminal sends the PUSCH according to the repeated transmission pattern.
In some embodiments, the indication information is used to indicate whether at least one of an uplink timeslot, a downlink timeslot, a special timeslot, and a flexible timeslot in all timeslots is an available timeslot. For example, bitmap information may be generated by the embodiment in fig. 2 a.
Fig. 2a shows a schematic diagram of some embodiments of the disclosed method for repeated transmission of uplink information.
As shown in fig. 2a, the subcarrier spacing is 30KHz, and the air-interface delay of the voice packet is required to be 50 ms. In this case, the air interface delay includes 100 slots in total. The frame structure of 2.5ms double period is DDDSUDDSUU, D is down time slot, U is up time slot, S is special time slot.
In some embodiments, the network side notifies the terminal side whether all timeslots (including downlink timeslots, uplink timeslots, special timeslots, flexible timeslots, etc.) within the air interface delay are available timeslots through bitmap information. The size of the bitmap information is 100 bits, and 1bit corresponds to 1 time slot.
For example, in fig. 2a, which is a part of the pixels of the bitmap, the slots marked with shading are available slots. The available time slots include two downlink time slots and two uplink time slots.
In some embodiments, in the case that 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, in the case where the available slot is a downlink slot (D in the figure), the repeated transmission of the uplink information to be transmitted in the downlink slot is cancelled by the terminal side.
In some embodiments, the indication information is used to indicate the available time slots in at least one of the uplink time slots and the special time slots included in all the time slots. In this way, only at least one of the available uplink time slots or special time slots is transmitted, which can reduce signaling overhead. Bitmap information may be generated by the embodiment in fig. 2b, for example.
Fig. 2b is a schematic diagram illustrating another embodiment of the uplink information retransmission method according to the present disclosure.
As shown in fig. 2b, the sub-carrier spacing is 30KHz and the voice packet air-gap time requires 50 ms. In this case, the air interface delay includes 100 slots in total.
In some embodiments, the network side notifies the terminal side whether the uplink timeslot within the air interface delay is an available timeslot through bitmap information. For example, 30 uplink timeslots are shared in 100 timeslots, the size of the bitmap information is 30 bits, and 1-bit pixel information indicates 1 timeslot, and is respectively used to identify whether the uplink timeslot corresponding to each pixel information is an available timeslot.
For example, the frame structure of a 2.5ms double period is DDDSUDDSUU. In fig. 2b are part of the pixels of the bitmap, the slots marked with shading being available slots. The available slots include 3 uplink slots. And the terminal sends the PUSCH according to the uplink time slot indicated in the bitmap information.
In some embodiments, the 2.5ms monocycle frame structure is DDDSU, with 20 uplink slots in total in 100 slots. The network side sends bitmap information with the size of 20 bits, and the pixel information with 1bit indicates whether 1 uplink time slot is an available time slot or not; and the terminal side sends the PUSCH according to the time slot indicated in the bitmap information.
Fig. 3 shows a block diagram of some embodiments of an apparatus for repeated transmission of upstream information of the present disclosure.
As shown in fig. 3, the device 3 for repeatedly transmitting uplink information includes a determining unit 31, a transmitting unit 32, and a triggering unit 33.
The determining unit 31 determines all timeslots existing in the air interface delay according to the subcarrier interval.
The transmitting unit 32 transmits instruction information to the terminal side. The indication information is used for indicating available time slots which can be used for repeatedly transmitting uplink information in all time slots.
In some embodiments, the transmission unit 32 transmits bitmap information as the indication information to the terminal side. Each pixel information in the bitmap information identifies one of 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 slots, and each pixel information occupies 1 bit.
In some embodiments, the size of the bitmap information is determined according to a period in which available time slots appear in all configured time slots, and the bitmap information is used for indicating each available time slot in one period.
In some embodiments, the sending unit 33 sends the indication information to the terminal side by higher layer signaling. For example, the higher layer signaling includes RRC signaling, MAC signaling.
The triggering unit 33 triggers the repeated transmission of the uplink information, so that the terminal side repeatedly transmits the uplink information to be transmitted according to the indication information. For example, the triggering unit 33 triggers the repeat transmission by physical layer signaling.
In some embodiments, the indication information is used to indicate the available time slots in at least one of an uplink time slot, a downlink time slot, a special time slot and a flexible time slot included in all time slots; and under the condition that 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.
In some embodiments, the indication information is used to indicate the available time slots in at least one of the uplink time slots and the special time slots included in all the time slots.
