At present, a New Radio (NR) system design mainly aims at wide coverage of Enhanced Mobile Broadband (eMBB) services, high speed requirements, and Low delay and high reliability characteristics of Ultra Reliable and Low delay Communication (URLLC) services, but Low cost and large connection considerations are relatively deficient. For the requirements of more various terminals and use scenes in the future, such as terminal types of sensor devices, wearable devices, monitoring cameras and the like, the bandwidth size (100 MHz) and the number of transmitting and receiving antennas (4 transmitting and receiving 2 transmitting) in the current NR system exceed the requirements of the terminals and the use scenes, so in the future NR evolution party, the network design facing low-cost and low-energy terminal types is an important direction, and the requirements of the terminal type on network performance indexes are lower than those of the terminal types of the current smart phones and the like.
The low-cost and low-power terminal types are mainly sensor equipment, wearable equipment, monitoring cameras and the like. To keep costs down, the industry development is increased, which requires less terminal capabilities and complexity than those defined by current NR systems. For example, the bandwidth supported by the low-cost and low-power terminal is smaller than the system bandwidth defined by the current NR system, the number of receiving antennas is reduced to 2 or 1, the number of supported Multiple Input Multiple Output (MIMO) streams is also reduced, and the maximum transmission power is also reduced. Meanwhile, in order to control the maintenance cost, the requirements on energy consumption for supporting low-cost and low-energy terminals are also stricter, and the energy consumption of the part of the terminals needs to be reduced as much as possible.

Referring to fig. 1, fig. 1 is a block diagram of a wireless communication system to which an embodiment of the present invention is applicable. The wireless communication system includes a terminal 11 and a network device 12. The terminal 11 may also be referred to as a User terminal or a User Equipment (UE), where the terminal 11 may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or a vehicle-mounted Device, and the specific type of the terminal 11 is not limited in the embodiment of the present invention. The network device 12 may be a Base Station and/or a network element of a core network, wherein the Base Station may be a 5G or later-version Base Station (e.g., a gNB, a 5G NR NB, etc.), or a Base Station in other communication systems (e.g., an eNB, a WLAN access point, or other access points, etc.), wherein the Base Station may be referred to as a node B, an evolved node B, an access point, a Base Transceiver Station (BTS), a radio Base Station, a radio Transceiver, a Basic Service Set (BSS), an Extended Service Set (ESS), a node B, an evolved node B (eNB), a home node B, a home evolved node B, a WLAN access point, a WiFi node, or some other suitable term in the field, as long as the same technical effect is achieved, the Base Station is not limited to a specific technical vocabulary, and it should be noted that the Base Station in the NR system is only taken as an example in the embodiment of the present invention, but the specific type of the Base Station is not limited.
The base stations may communicate with the terminals 11 under the control of a base station controller, which may be part of the core network or some of the base stations in various examples. Some base stations may communicate control information or user data with the core network through a backhaul. In some examples, some of these base stations may communicate with each other directly or indirectly over backhaul links, which may be wired or wireless communication links. A wireless communication system may support operation on multiple carriers (waveform signals of different frequencies). A multi-carrier transmitter can transmit modulated signals on the multiple carriers simultaneously. For example, each communication link may be a multi-carrier signal modulated according to various radio technologies. Each modulated signal may be transmitted on a different carrier and may carry control information (e.g., reference signals, control channels, etc.), overhead information, data, and so on.
The base station may communicate wirelessly with the terminal 11 via one or more access point antennas. Each base station may provide communication coverage for a respective coverage area. The coverage area of an access point may be divided into sectors that form only a portion of the coverage area. A wireless communication system may include different types of base stations (e.g., macro, micro, or pico base stations). The base stations may also utilize different radio technologies, such as cellular or WLAN radio access technologies. The base stations may be associated with the same or different access networks or operator deployments. The coverage areas of different base stations (including coverage areas of base stations of the same or different types, coverage areas utilizing the same or different radio technologies, or coverage areas belonging to the same or different access networks) may overlap.
The communication links in a wireless communication system may comprise an Uplink for carrying Uplink (UL) transmissions (e.g., from terminal 11 to network device 12) or a Downlink for carrying Downlink (DL) transmissions (e.g., from network device 12 to terminal 11). The UL transmission may also be referred to as reverse link transmission, while the DL transmission may also be referred to as forward link transmission. Downlink transmissions may be made using licensed frequency bands, unlicensed frequency bands, or both. Similarly, uplink transmissions may be made using licensed frequency bands, unlicensed frequency bands, or both.
As described in the background, the low-cost and low-power terminal has reduced terminal capabilities (number of receiving antennas, maximum transmission power), and the coverage capability of each physical channel is deteriorated compared to the terminal supported by the current NR system, wherein the reduction of the number of antennas, for example, the reduction of the terminal from 2-transmission 4-reception to 1-transmission 2-reception, results in the reduction of the coverage performance by 3dB. To compensate for the loss of coverage due to the reduced terminal capability, one possible way is to repeat the transmission of each physical channel, for example, 2 times, which may result in a coverage enhancement effect of about 3dB. In addition, due to the size and process limitation of the low-cost and low-energy terminal, the antenna gain of the low-cost and low-energy terminal is further reduced, even 10-15 dB lower than that of a common mobile phone.
Taking repeated transmission of a Physical Downlink Shared Channel (PDSCH) and a Physical Uplink Shared Channel (PUSCH) as an example, the network side configures the number of times of repeated transmission (e.g. 2 times, 4 times, or 8 times) through a high-level signaling, and indicates time-frequency domain resource allocation through Downlink Control Information (DCI), and the time-frequency domain resource allocation of each transmission is the same. The terminal performs repeated transmission of the PUSCH on N consecutive slots, and if a certain slot does not satisfy the transmission condition (for example, when the PUSCH is repeatedly transmitted, the current slot is a downlink slot), the terminal ignores the transmission, but N continues to count, that is, the number of times of PUSCH actually transmitted by the terminal is less than N.
For a low-cost and low-power terminal, due to the reduction of the number of transmitting antennas and the maximum transmitting power, and the reduction of the antenna gain and the increase of the penetration loss, the coverage of the uplink channel, for example, the PUSCH channel, may be reduced, so that the coverage gap may be made up by using the repeated transmission method, and a larger number of repetitions, such as 16 repetitions, 32 repetitions, 64 repetitions, and the like, may be introduced.
If the above-mentioned repeated transmission of the PUSCH is used, the low-cost and low-power terminal may occupy the physical channel resource for a long time. Considering the coexistence scenario of the low-cost low-capability terminal and the eMBB terminal, for a smaller-bandwidth operator or a terminal that does not support dynamic bandwidth part (BWP), if the low-cost low-capability terminal occupies physical channel resources for a long time, the transmission opportunity of the eMBB terminal is reduced, and the delay of the eMBB terminal is increased. Especially for the current TDD frame structure, the uplink timeslot resources are less, and the problem that such resources are occupied by low-cost and low-power terminals for a long time is more serious.
In order to solve at least one of the above problems, an embodiment of the present invention provides a repeated transmission method, which can reduce or avoid problems that some terminals (e.g., low-cost and low-capability terminals) occupy air interface resources for a long time, so that transmission opportunities of other terminals or services are reduced and delay is increased. The embodiment of the invention divides continuous repeated transmission into a plurality of discontinuous parts, and resources between the discontinuous parts can be used for scheduling other services or other terminals. Meanwhile, if the base station already receives the data sent by the terminal before the predefined maximum repetition number, the base station can stop the subsequent data transmission of the terminal in time, so that the problem of resource waste can be solved.
Referring to fig. 2, a method for repeating transmission according to an embodiment of the present invention, when applied to a terminal side, includes:
step 21, the terminal repeatedly sends the first service data on at least one discontinuous transmission resource in the time domain according to the indication information or the configuration information sent by the network
Through the above steps, the terminal performs repeated transmission through at least one transmission resource which is discontinuous in the time domain when the terminal repeatedly transmits the first service data. In the above repeated transmission process, the transmission is no longer performed in connection with the transmission resources occupying the time domain continuously, so that the network side can schedule other service data of the terminal or service data of other terminals by using the interval between the transmission resources, thereby reducing or avoiding the problems of reduction of transmission opportunities and increase of time delay of other terminals or services caused by the terminal occupying air interface resources for a long time.
Here, it should be noted that, in the embodiment of the present invention, the transmission resource is a segment of resource continuous in a time domain, and the at least one transmission resource is one or more transmission resources discontinuous in the time domain, specifically, time intervals between adjacent transmission resources may be the same or different, which is not specifically limited in the embodiment of the present invention.
In addition, the terminal may repeatedly transmit the first service data on each transmission resource, that is, the number of times of transmitting the first service data on each transmission resource may be multiple times, and the number of times of transmitting on different transmission resources may be the same or different. Herein, repeatedly transmitting the first traffic data on one transmission resource is referred to as one-time repeated transmission, and thus, one-time repeated transmission may perform multiple transmissions of the first traffic data.
Repeatedly transmitting the first traffic data on a first transmission resource of the at least one transmission resource, also referred to herein as first repeatedly transmitting the first traffic data; and repeatedly transmitting the first traffic data on other transmission resources subsequent to the first transmission resource of the at least one transmission resource, also referred to herein as repeatedly sending the first traffic data again.
Therefore, the step of repeatedly transmitting the first service data on at least one transmission resource discontinuous in the time domain in step 21 may include:
repeatedly sending the first service data for the first time; and (c) a second step of,
and repeatedly sending the first service data again.
According to some embodiments of the present invention, the terminal may be indicated with the next transmission resource and/or transmission number through dynamic signaling sent by the network. At this time, the first repeatedly transmitting the first service data may include:
a) The terminal detects first indication information sent by a network, wherein the first indication information is used for indicating first transmission resources and/or first times;
b) And 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 times indicated by the first indication information.
Accordingly, the repeatedly sending the first service data again may include:
a) Detecting second indication information sent by a network based on a time interval and/or a detection window obtained in advance, wherein the second indication information is used for indicating a second time domain resource and/or a second time;
b) And under the condition that the second indication information is detected, repeatedly sending the first service data to the network on a second transmission resource according to the second indication information and/or the first indication information and/or the time interval. Here, the terminal may stop transmitting the first service data if the second indication information is not detected.
Of course, in the embodiment of the present invention, the terminal may also count the number of times of sending the first service data. After the first service data is repeatedly sent for the first time or the first service data is repeatedly sent again, if the sending times of the first service data reaches a preset number, the sending of the first service data may be stopped.
In the above embodiment, whether or not the repeat transmission needs to be continued is indicated by dynamic signaling (second indication information). The dynamic signaling may also indicate specific transmission resources and/or transmission times when repeated transmissions are required.
In addition, the time interval and/or the detection window for the terminal to detect the second indication information may be configured in advance by higher layer signaling (e.g. RRC signaling sent by the network), or may be obtained from the first indication information. The detection window may be represented by a length of the detection window and/or a distance from a previous transmission resource.
According to further embodiments of the present invention, the terminal may be instructed by a reception acknowledgement information (ACK) sent by the network to terminate the repeat transmission. At this time, before the step 21, the terminal may further receive a higher layer signaling (e.g. RRC signaling) sent by the network, where the higher layer signaling is used to configure at least one of the following parameters for the terminal: maximum transmission times, transmission times on transmission resources, time intervals between transmission resources, detection windows or search spaces for detecting HARQ-ACK information between transmission resources, the transmission resources being discontinuous in time domain.
In this way, in step 21, the terminal may repeatedly send the first service data corresponding to the transmission times to the network on the current transmission resource according to the transmission resource configured by the network and the transmission times on the transmission resource.
Further, in step 21, the terminal may further detect, according to a time interval between transmission resources configured by the network or a detection window or a search space for detecting HARQ-ACK information between transmission resources, reception acknowledgement information of the first service data sent by the network:
stopping the repeated sending of the first service data under the condition that the receiving confirmation information of the first service data is detected;
and under the condition that the receiving confirmation information of the first service data is not detected, repeatedly sending the first service data with corresponding transmission times to the network on the next transmission resource.
Several embodiments of repeated transmission on the terminal side are provided above. Further description will be made from the base station side.
Referring to fig. 3, a method for repeating transmission according to an embodiment of the present invention, when applied to a base station, includes:
step 31, the base station receives the first service data repeatedly sent by the first terminal on a plurality of discontinuous transmission resources in the time domain.
In this way, the base station may schedule the second service data of the first terminal and/or the service data of other terminals by using the intermediate resource between the transmission resources, so as to reduce or avoid the problem that the terminal occupies the air interface resource for a long time, which causes reduction of transmission opportunities and increase of delay of other terminals or services.
According to some embodiments of the present invention, in the step 31, the base station may perform the receiving process in the following manner:
a) And sending first indication information to a first terminal, wherein the first indication information is used for indicating a first transmission resource and/or a first number of times that the first terminal repeatedly sends first service data on the first transmission resource.
B) Receiving first service data sent by the first terminal on the first transmission resource, wherein the process is ended when the first service data sent by the first terminal is received on the first transmission resource; and when the first service data sent by the first terminal is not received on the first transmission resource, continuing to send the next indication information to the first terminal, and continuing to receive the first service data sent by the first terminal on the transmission resource indicated by the next indication information.
Here, when the base station continues to send the next indication information to the first terminal, the base station may specifically send the indication information to the first terminal in a time interval between the transmission resources and/or a detection window after the transmission resources.
In addition, the base station may send a higher layer signaling to the terminal, where the higher layer signaling is used to indicate a time interval between the transmission resources and/or a detection window after the transmission resources; and/or 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 this way, the base station may indicate the time interval and/or the detection window to the terminal. Typically, the length of the detection window is no greater than the time interval.
According to other embodiments of the present invention, before step 31, the base station may configure a plurality of transmission resources which are discontinuous in a time domain, a number of transmissions on the transmission resources, a time interval between the transmission resources, and a detection window or a search space for detecting HARQ-ACK information between the transmission resources for the first terminal.
Then, when receiving the first service data repeatedly sent by the first receiving terminal in step 31, the base station may receive the first service data sent by the first receiving terminal on the current transmission resource, where if the first service data sent by the first receiving terminal is received on the transmission resource, the base station sends a reception confirmation message of the first service data to the first receiving terminal in the time interval, the detection window, or the search space, and ends the process; and if the first service data sent by the first terminal is not received on the transmission resource, continuing to receive the first service data sent by the first terminal when the next transmission resource arrives.
The implementation of the method of the embodiment of the present invention at the terminal and the base station side is described above respectively. The invention is further described below with the aid of several specific exemplary figures.
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 indicates, through higher layer signaling configuration or first DCI (DCI #1 in fig. 4), a time interval between terminal transmissions of PUSCH and/or a time window for detecting second DCI (DCI #2 in fig. 4) after completion of PUSCH repeated transmission. Wherein the indication information of the detection window comprises at least one of: the length of the detection window and/or the distance from the PUSCH transmission (e.g. the end position of the PUSCH). The first DCI carries an information field for indicating the following information: frequency domain resource allocation, time domain resource allocation in a time slot, the number of repetitions of the first PUSCH transmission, and the like.
And after receiving the first DCI, the terminal performs the first PUSCH repeated transmission according to the indication of the first DCI. And after the terminal completes the first PUSCH repeated transmission, detecting the second DCI in the time interval or the detection window. The second DCI carries an information field for indicating PUSCH repetition transmission times and/or time domain resource allocation.
And if the terminal detects the second DCI, the terminal determines transmission resources according to the PUSCH repeated transmission times and/or time domain resource allocation indicated by the second DCI and the frequency domain resource allocation indicated by the first DCI. Specifically, the second DCI indicates a starting slot and a slot number of a terminal transmitting a PUSCH. If the terminal does not detect the second DCI, the terminal stops transmitting the PUSCH.
Fig. 5 is an example in which the base station pre-configures an interval of each transmission resource and the number of transmission resources through higher layer signaling and instructs the terminal to terminate the repetitive transmission through ACK. Wherein:
the high layer signaling or the scheduling DCI configures the maximum number of PUSCH transmission resources, the repeated transmission times in each transmission resource and the time interval between each transmission resource for the terminal.
In addition, the higher layer signaling may also configure the terminal with a detection window or search space between each transmission resource (PUSCH segment) for the terminal to detect HARQ-ACK information. Wherein the indication information of the detection window comprises at least one of: the length of the detection window and/or the distance from the PUSCH transmission.
And if the terminal does not detect the HARQ-ACK information in the time interval or the detection window or the search space, continuing to transmit a PUSCH segment according to the configuration of the higher layer signaling. And if the terminal detects the HARQ-ACK information in the time interval or the detection window or the search space, stopping transmitting the PUSCH.
It can be seen from the above examples that, in the embodiments of the present invention, discontinuous transmission resources are used to perform repeated transmission of a certain terminal, so that a network side may perform scheduling of other services of the terminal or services of other terminals by using an interval between transmission resources, and the problems of reduction in transmission opportunities and increase in delay of other terminals or services due to long-time occupation of air interface resources by the terminal can be reduced or avoided.
