Future-oriented requirements for more diverse terminals and usage scenarios, such as sensor devices, wearable devices, surveillance cameras, and other terminal types. The bandwidth (100MHz) and the number of transceiver antennas (4 receiving and 2 transmitting) in the current NR system exceed this part Therefore, in the future NR evolution, network design for low-cost, low-capacity terminal types is an important direction, and the requirements for network performance indicators of this type of terminal will also be lower than the current requirements. Terminal types such as smart phones.

Low-cost, low-capacity terminal types are mainly sensor devices, wearable devices, surveillance cameras, etc. In order to control costs and increase industry development, its terminal capabilities and complexity need to be less than those defined by the current NR system. For example, the bandwidth supported by low-cost and low-capacity terminals is smaller than the system bandwidth defined by the current NR system, the number of receiving antennas will be reduced to 2 or 1, the number of supported multiple input multiple output (MIMO) streams will also be reduced, and the maximum transmit power Will also decrease.

Please refer to FIG. 1, which shows a block diagram of a wireless communication system to which an embodiment of the present disclosure can be applied. The wireless communication system includes a terminal 11 and a network device 12. Among them, the terminal 11 may also be called a user terminal or a user equipment (UE), and the terminal 11 may be a mobile phone, a tablet (Personal Computer), a laptop (Laptop Computer), or a personal digital assistant (Personal Digital Assistant). , PDA), mobile Internet device (Mobile Internet Device, MID), wearable device (Wearable Device) or vehicle-mounted device and other terminal-side devices, it should be noted that the specific type of terminal 11 is not limited in the embodiments of the present disclosure . The network device 12 may be a base station and/or a core network element, where the above-mentioned base station may be a base station of 5G and later versions (for example: gNB, 5G NR NB, etc.), or a base station in other communication systems (for example: eNB, WLAN Access point, or other access points, etc.), where the base station can be called Node B, Evolved Node B, Access Point, Base Transceiver Station (BTS), Radio Base Station, Radio Transceiver, Basic Service Set (Basic Service Set, BSS), Extended Service Set (Extended Service Set, ESS), Node B, Evolved Node B (eNB), Home Node B, Home Evolved Node B, WLAN Access Point, WiFi Node or As long as some other suitable terminology in the field achieves the same technical effect, the base station is not limited to a specific technical vocabulary. It should be noted that in the embodiments of the present disclosure, only the base station in the NR system is taken as an example, but not The specific type of base station is not limited.

The base station may communicate with the terminal 11 under the control of the base station controller. In various examples, the base station controller may be a part of a core network or some base stations. Some base stations can communicate control information or user data with the core network through the backhaul. In some examples, some of these base stations may directly or indirectly communicate with each other through a backhaul link, which may be a wired or wireless communication link. The wireless communication system can support operations on multiple carriers (waveform signals of different frequencies). Multi-carrier transmitters can simultaneously transmit modulated signals on these multiple carriers. For example, each communication link may be a multi-carrier signal modulated according to various radio technologies. Each modulated signal can be sent on a different carrier and can carry control information (for example, reference signals, control channels, etc.), overhead information, data, and so on.

The base station may perform wireless communication with the terminal 11 via one or more access point antennas. Each base station can provide communication coverage for its corresponding coverage area. The coverage area of an access point can be divided into sectors that constitute only a part of the coverage area. The wireless communication system may include different types of base stations (e.g., macro base stations, micro base stations, or pico base stations). The base station can also utilize different radio technologies, such as cellular or WLAN radio access technologies. The base stations can be associated with the same or different access networks or operator deployments. The coverage areas of different base stations (including coverage areas of the same or different types of base stations, coverage areas using the same or different radio technologies, or coverage areas belonging to the same or different access networks) may overlap.

The communication link in the wireless communication system may include an uplink for carrying uplink (UL) transmission (for example, from the terminal 11 to the network device 12), or for carrying a downlink (DL) Transmission (e.g., from the network device 12 to the terminal 11) downlink. UL transmission may also be referred to as reverse link transmission, and DL transmission may also be referred to as forward link transmission. Downlink transmission can use licensed frequency bands, unlicensed frequency bands, or both. Similarly, uplink transmission can be performed using licensed frequency bands, unlicensed frequency bands, or both.

As described in the background art, low-cost and low-capacity terminals have reduced terminal capabilities (number of receiving antennas, maximum transmit power). Compared with the terminals supported by the current NR system, the coverage of each physical channel will be reduced. Deterioration, where the number of antennas is reduced, for example, the terminal is reduced from 2 transmitters and 4 receivers to 1 transmitter and 2 receivers, which will reduce the coverage performance by 3dB. In order to make up for the loss of coverage caused by the reduced terminal capability, one possible way is to repeatedly send each physical channel. For example, one physical channel is repeatedly sent twice, which can bring about a 3dB coverage enhancement effect. In addition, due to the size and process limitations of low-cost and low-capacity terminals, the antenna gain will be further reduced, even 10-15dB lower than that of ordinary mobile phones.

Taking the repeated transmission of the physical downlink shared channel (PDSCH) and the physical uplink shared channel (PUSCH) as an example, the network side configures the number of repeated transmissions N times (such as 2 times, 4 times or 8 times) through high-level signaling, and then controls the downlink The information (DCI) indicates time-frequency domain resource allocation, and the time-frequency domain resource allocation for each transmission is the same. The terminal performs repeated PUSCH transmission on N consecutive time slots. If a certain time slot does not meet the transmission conditions (for example, when the PUSCH is repeatedly transmitted, the current time slot is a downlink time slot), the terminal ignores this transmission, but N continues to count, that is, the number of PUSCH actually transmitted by the terminal will be less than N times.

For low-cost and low-capacity terminals, due to the reduction in the number of transmit antennas and maximum transmit power, as well as the reduction in antenna gain and the increase in penetration loss, the coverage of uplink channels such as PUSCH channels will be reduced. Therefore, repeated transmissions can make up for the coverage gap. At the same time, a larger number of repetitions such as 16, 32, 64, etc. can be introduced.

If the repeated transmission of the PUSCH is used, low-cost and low-capacity terminals will occupy physical channel resources for a long time. Considering the coexistence of low-cost and low-capacity terminals and eMBB terminals, for operators with smaller bandwidths or terminals that do not support dynamic switching of the bandwidth part (BWP), if low-cost and low-capability terminals occupy physical channel resources for a long time, eMBB will be reduced. The transmission opportunity of the terminal increases the delay of the eMBB terminal. Especially for the current TDD frame structure, there are fewer uplink time slot resources, and the problem of long-term occupation of such resources by low-cost and low-capacity terminals will be more serious.

In order to solve at least one of the above problems, embodiments of the present disclosure propose a repeated transmission method, which can reduce or avoid certain terminals (such as low-cost and low-capacity terminals) occupying air interface resources for a long time, causing transmission opportunities for other terminals or services. The problem of reduction and increase in latency. The embodiment of the present disclosure divides the continuous repeated transmission into multiple discontinuous parts, and the resources between the discontinuous parts can be used to schedule other services or other terminals. At the same time, if the base station has received the data sent by the terminal before the pre-defined maximum number of repetitions, the base station can stop the subsequent data transmission of the terminal in time, which can cause a waste of resources.

Referring to FIG. 2, a method for repeated transmission provided by an embodiment of the present disclosure, when applied to the terminal side, includes:

Step 21: The terminal repeatedly sends the first service data on at least one transmission resource that is not continuous in the time domain according to the instruction information or configuration information sent by the network.

Through the above steps, when the terminal repeatedly sends the first service data, it will repeat the transmission through at least one transmission resource that is not continuous in the time domain. In the above repeated transmission process, the continuous transmission resources in the time domain are no longer contacted for transmission. Therefore, the network side can use the interval between the transmission resources to schedule other service data of the terminal or other terminal service data, thereby reducing Or to prevent the terminal from occupying air interface resources for a long time, resulting in the problem of reduced transmission opportunities and increased delay of other terminals or services.

Here, it should be noted that the transmission resource in the embodiment of the present disclosure is a continuous resource in the time domain, and the at least one transmission resource is one or more transmission resources that are discontinuous in the time domain. The time interval between adjacent transmission resources may be the same or different, which is not specifically limited in the embodiment of the present disclosure.

In addition, on each transmission resource, the terminal may repeatedly send the first service data, that is, the number of times the first service data is sent on each transmission resource may be multiple times. The number of sending can be the same or different. Herein, the repeated transmission of the first service data on one transmission resource is referred to as one-time repeated transmission. Therefore, one repeated transmission may perform multiple transmissions of the first service data.

Repeatedly transmitting the first service data on the first transmission resource in the at least one transmission resource, which is also referred to herein as the first repeated transmission of the first service data; and in the at least one transmission resource Repeated transmission of the first service data on other transmission resources after the first transmission resource is also referred to herein as repeated transmission of the first service data again.

Therefore, the step of repeatedly sending the first service data on at least one transmission resource that is not continuous in the time domain in the above step 21 may include:

Sending the first service data repeatedly for the first time; and,

Repeat sending the first service data again.

According to some embodiments of the present disclosure, dynamic signaling sent by the network may be used to indicate the next transmission resource and/or the number of transmissions of the terminal. At this time, the first retransmission of the first service data may include:

A) The terminal detects the first indication information sent by the network, where the first indication information is used to indicate the first transmission resource and/or the first number of times;

B) The terminal repeatedly sends the first service data to the network on the first transmission resource according to the first transmission resource and/or the first number indicated by the first indication information.

Correspondingly, the repeated sending of the first service data again may include:

A) Based on a pre-obtained time interval and/or detection window, detecting second indication information sent by the network, where the second indication information is used to indicate the second time domain resource and/or the second number of times;

B) In the case of detecting the second indication information, according to the second indication information and/or the first indication information and/or the time interval, repeatedly sending the first indication information to the network on the second transmission resource One business data. Here, if the second indication information is not detected, the terminal may stop sending the first service data.

Of course, in the embodiment of the present disclosure, the terminal may also count the number of times the first service data is sent. After the first service data is repeatedly sent or the first service data is repeatedly sent again, if the number of times the first service data is sent reaches a preset number of times, the sending of the first service data may be stopped.

In the above embodiment, dynamic signaling (second indication information) is used to indicate whether to continue repeated transmission. The dynamic signaling may also indicate specific transmission resources and/or transmission times when repeated transmission is required.

In addition, the time interval and/or the detection window for the terminal to detect the second indication information may be pre-configured by high-level signaling (such as RRC signaling sent by the network), or may be obtained from the above-mentioned first indication information. The detection window may be represented by the length of the detection window and/or the distance from the previous transmission resource.

According to other embodiments of the present disclosure, the terminal may be instructed to terminate the repeated transmission through the reception confirmation information (ACK) sent by the network. At this time, before step 21, the terminal may also receive high-level signaling (such as RRC signaling) sent by the network, and the high-level signaling is used to configure at least one of the following parameters for the terminal: the maximum number of transmissions, The number of transmissions on the transmission resource, the time interval between the transmission resources, the detection window or search space for detecting HARQ-ACK information between the transmission resources, and the transmission resources are not continuous in the time domain.

In this way, in step 21, the terminal may repeatedly send the first service data corresponding to the number of transmissions to the network on the current transmission resource according to the transmission resource configured by the network and the number of transmissions on the transmission resource.

Furthermore, in the above step 21, the terminal may also detect the HARQ-ACK information detection window or search space according to the time interval between the transmission resources configured by the network or the detection window or the search space between the transmission resources, and detect the first transmission from the network. A confirmation message for receiving business data:

The foregoing provides several embodiments for repeated transmission on the terminal side. The following further describes from the base station side.

Referring to FIG. 3, the repeated transmission method provided by the embodiment of the present disclosure, when applied to the base station side, includes:

Step 31: The base station receives the first service data repeatedly sent by the first terminal on multiple transmission resources that are not continuous in the time domain.

In this way, the base station can use the intermediate resources between the transmission resources to schedule the second service data of the first terminal and/or the service data of other terminals, thereby reducing or preventing the terminal from occupying air interface resources for a long time, resulting in The problem of reduced transmission opportunities and increased delay of other terminals or services.

According to some embodiments of the present disclosure, in the foregoing step 31, the base station may perform receiving processing in the following manner:

A) Send first indication information to the first terminal, where the first indication information is used to indicate the first transmission resource and/or the first terminal that repeatedly sends the first service data on the first transmission resource. frequency.

B) On the first transmission resource, receiving the first service data sent by the first terminal, wherein, in the case of receiving the first service data sent by the first terminal on the first transmission resource , End the process; and in the case that the first service data sent by the first terminal is not received on the first transmission resource, continue to send the next instruction information to the first terminal, and continue to the next Receiving the first service data sent by the first terminal on the transmission resource indicated by the indication information.

Here, when the base station continues to send the next indication information to the first terminal, it may specifically send the first terminal to the first terminal within the time interval between the transmission resources and/or the detection window after the transmission resources. The terminal sends the instruction information.

In addition, the base station may send high-level signaling to the terminal, where the high-level signaling is used to indicate the time interval between the transmission resources and/or the detection window after the transmission resource; and/or, the The base station further indicates the time interval between the transmission resources and/or the detection window after the transmission resources in the first indication information. In the above manner, the base station can indicate the time interval and/or the detection window to the terminal. Generally, the length of the detection window is not greater than the time interval.

According to other embodiments of the present disclosure, before the above step 31, the base station may configure multiple non-contiguous transmission resources in the time domain for the first terminal, the number of transmissions on the transmission resources, and the time interval between the transmission resources, And, a detection window or search space for detecting HARQ-ACK information between transmission resources.

Then, when receiving the first service data repeatedly sent by the first terminal in step 31, the base station may receive the first service data sent by the first terminal on the current transmission resource, where if If the first service data sent by the first terminal is received on the transmission resource, in the time interval, the detection window or the search space, the reception confirmation information of the first service data is sent to the first terminal , And end the process; if the first service data sent by the first terminal is not received on the transmission resource, when the next transmission resource arrives, continue to receive the first service data sent by the first terminal.

The implementation of the method in the embodiments of the present disclosure on the terminal and base station sides has been described above. The following further describes the present disclosure through several specific example diagrams.

Referring to FIG. 4, in this example, the base station indicates the transmission duration of each transmission resource through dynamic signaling. Specifically, the base station uses high-layer signaling to configure or the first DCI (DCI#1 in FIG. 4) to indicate the time interval between PUSCH transmission by the terminal and/or to detect the second DCI (DCI in FIG. 4) after repeated PUSCH transmission is completed. #2) The time window. The indication information of the detection window includes at least one of the following: the length of the detection window and/or the distance after PUSCH transmission (such as the end position of the PUSCH). The first DCI carries an information field, which is used to indicate the following information: frequency domain resource allocation, time domain resource allocation in a time slot, and the number of repetitions of the first PUSCH transmission, etc.

After receiving the first DCI, the terminal performs the first PUSCH repeated transmission according to the indication of the first DCI. After completing the first PUSCH repeated transmission, the terminal detects the second DCI within the time interval or detection window. The second DCI carrying information field is used to indicate the number of PUSCH repeated transmissions and/or time domain resource allocation.

If the terminal detects the second DCI, the terminal determines the transmission resource according to the number of PUSCH repeated transmissions indicated by the second DCI type and/or the time domain resource allocation and the frequency domain resource allocation indicated by the first DCI type. Specifically, the second DCI indicates the starting time slot and the number of time slots for the terminal to transmit PUSCH. If the terminal does not detect the second DCI, the terminal stops transmitting PUSCH.

Fig. 5 is an example in which the base station pre-configures the interval of each transmission resource and the number of transmission resources through high-level signaling, and instructs the terminal to terminate repeated transmission through ACK. in:

High-level signaling or scheduling DCI configures the maximum number of PUSCH transmission resources for the terminal, the number of repeated transmissions in each transmission resource, and the time interval between each transmission resource.

In addition, high-level signaling can also configure a detection window or search space for the terminal to detect HARQ-ACK information between each transmission resource (PUSCH segment). The indication information of the detection window includes at least one of the following: the length of the detection window and/or the distance after PUSCH transmission.

If the terminal does not detect HARQ-ACK information within the time interval or detection window or search space, it continues to transmit a PUSCH segment according to the configuration of the higher layer signaling. If the terminal detects HARQ-ACK information within the time interval or detection window or search space, it stops transmitting PUSCH.

It can be seen from the above examples that the embodiment of the present disclosure uses discontinuous transmission resources for repeated transmission of a certain terminal, so that the network side can use the interval between transmission resources to perform other services of the terminal or services of other terminals. Scheduling can reduce or prevent the terminal from occupying air interface resources for a long time, causing the problems of reduced transmission opportunities and increased delays for other terminals or services.
