Detailed ways

The application will be further described in detail below in conjunction with the drawings and embodiments.

In related technologies, as the complexity and flexibility of NR Light terminals decrease, coverage capabilities will shrink. For example, when a smaller number of antennas are used for reception, compared to ordinary enhanced mobile broadband (eMBB) service terminals of NR , The receiving performance of NR Light terminals will deteriorate, resulting in reduced coverage. In addition, the smaller size requirements of NR Light terminals and some technological limitations have caused the antenna gain of NR Light terminals to be further reduced, even 10 to 15dB lower than that of ordinary mobile phone antennas. If eMBB coverage is used as the coverage target, it is necessary to The NR Light terminal is designed for coverage enhancement.

The most intuitive way to achieve coverage enhancement is to use repeated transmission. The more repeated transmissions, the greater the coverage gain that can be improved. For the uplink direction, since the power class may be further reduced, for example, from 23 dBm to 14 dBm, the number of repetitions will be further increased compared to the downlink direction. Then, when the NR Light terminal needs more repeated transmissions to ensure coverage, in the coexistence scenario of the NR Light terminal and the eMBB terminal (that is, the terminal that uses the eMBB service), for operators with smaller bandwidth, or for Access to the same bandwidth, but for eMBB terminals that do not have the ability to dynamically switch the bandwidth part (BWP), multiple repeated transmissions of NR Light terminals will occupy transmission resources for a long time, resulting in eMBB terminals that do not have the ability to dynamically switch BWPs. The transmission is delayed for a long time (that is, the transmission delay is increased), or the transmission rate is low, which results in low transmission efficiency of eMBB terminals that do not have the ability to dynamically switch BWP. For scenarios where the time slot is a TDD frame structure Said that, since the time slot in a certain direction does not always exist, this situation will be more serious.

Based on this, in various embodiments of the present application, the network device instructs the terminal to repeat the transmission time slot or the transmission interval of the repeated transmission in the repeated transmission process.

Here, it is worth noting that the solutions in the embodiments of the present application are not limited to being applied to NR Light scenarios, and are also applicable to other scenarios that involve multiple repeated transmissions to improve coverage performance. When a terminal that repeatedly transmits and a terminal that does not require repeated transmission coexists, the solution in the embodiment of the present application may also be adopted.

In the embodiments of the present application, the uplink refers to the direction in which the terminal transmits information (including service data, control information, reference signals, etc.) to the network device; the downlink refers to the direction in which the network device transmits information to the terminal.

Wherein, in actual application, the network device may be a base station, such as a next-generation node B (gNB), etc.

The embodiment of the present application provides an information transmission method, which is applied to a network device. As shown in FIG. 1, the method includes:

Step 100: Determine the time slot related information that the terminal can use for repeated transmission;

Step 101: Send instruction information to the terminal.

Wherein, the instruction information indicates one of the following:

Time slots available for repeated transmission;

The transmission interval for repeated transmissions.

Wherein, in actual application, in step 100, the network device can determine that the terminal can be used for repeated transmission based on the situation of different types of terminals coexisting on the same time domain resource (such as the coexistence of NR Light terminal and eMBB terminal) Time slot related information.

Correspondingly, the indication information is determined based on the determined time slot related information.

The time slot available for repeated transmission refers to the time slot resource used by the terminal when the terminal is configured with the repeated transmission function. For example, when the terminal turns on the repeated transmission function, the terminal uses certain time slots configured by the network as available candidate resources for repeated transmission.

In practical applications, the indication information may be sent to the terminal through high-level signaling, or the indication information may be sent to the terminal through control information.

Wherein, the high-level signaling may include radio resource control (RRC) signaling or media access signaling (MAC) signaling, etc.

The control information may include downlink control information (DCI) and the like. By sending the instruction information through the control information, the purpose of dynamic control can be achieved.

If the indication information indicates a time slot that can be used for repeated transmission, that is, in the case where the indication information indicates a time slot that can be used for repeated transmission, the network device can indicate a terminal time slot or subframe pattern (in English, it can be expressed as pattern) to indicate the time slot that can be used for repeated transmission by the terminal. At this time, the indication information indicates the time slot or subframe pattern used to determine the time slot that can be used for repeated transmission, that is, the indication information indicates The time slot or subframe pattern indicates a time slot that can be used for repeated transmission, and the indicated pattern specifically indicates a time slot that can be used for repeated transmission by the terminal.

Here, in actual application, the network device can select a time slot or subframe pattern from the time slot or subframe patterns configured for the terminal to indicate the time slot that the terminal can use for repeated transmission. In this case, the time slot pattern Or, the subframe pattern is used as a means for the network to configure available candidate resources for the terminal. In the pattern, it is necessary to clarify which time slots are available candidate resources for repeated transmission by the terminal.

Based on this, in an embodiment, the method may further include:

Select a time slot or subframe pattern from at least one time slot or subframe pattern configured by the network;

The indication information indicates the selected time slot or subframe pattern.

Among them, in actual application, the network equipment can be based on the coexistence of the eMBB terminal and the NR Light terminal on the same BWP (which can be understood as the same time domain resource), according to the situation of the eMBB terminal, from the time slot configured for the terminal Or select a time slot or subframe pattern in the subframe pattern. For example, when the eMBB terminal has more services, the selected timing or subframe pattern can reserve more time slots for the eMBB terminal, that is, for repeated transmission There are fewer time slots.

In practical applications, the time slot or subframe pattern can be implemented by bitmap, that is, the bitmap is used to indicate which time slots are available for repeated transmission by the terminal.

Wherein, in an embodiment, the method may further include:

Configure at least one time slot or subframe pattern for the terminal through a bitmap.

Here, in actual application, the network device can configure multiple time slots or subframe patterns for the terminal through high-level signaling, and each configured time slot or subframe pattern corresponds to a different bitmap; and it is dynamically indicated to take effect through control information. The time slot or subframe pattern, for example, the effective time slot or subframe pattern is indicated by 1 bit, so as to achieve the purpose of dynamically controlling the available uplink and downlink time slots.

Among them, in actual application, the length of the bitmap can be configured or predefined (can be understood as a prescribed).

Specifically, the length of the bitmap is associated with the period of the TDD configuration, or the length of the bitmap is associated with the number of time slots corresponding to the predefined time length.

Wherein, in actual application, the TDD configuration includes TDD uplink and downlink configuration.

When the bitmap is used to indicate which time slots of the terminal can be used for repeated transmission of the terminal, it can be considered that the time slot that can be used for repeated transmission of the terminal is periodically determined, and the length of the period is the time corresponding to the bitmap. The length of the slot or subframe.

Exemplarily, assuming that the current 5ms TDD frame structure is used (the TDD configuration cycle is 5ms), the 30KHz subcarrier interval corresponds to 10 time slots, correspondingly; the TDD uplink and downlink configuration is: DDDSUUDDSUU; it can be configured through high-level signaling Two kinds of bitmaps are used to indicate the time slot that the terminal can use for repeated transmission of the terminal. The length of the bitmap is 10 bits, and they are:

The bitmap of pattern 1: 11001 11011, which means DDXXUDDXUU;

The bitmap of pattern 2: 11111 11111, which means DSUUDDSUU.

Among them, D indicates that the downlink is available, U indicates that the uplink is available, X indicates that it is not available, and S indicates that both the uplink and the downlink are available.

The time slot at position 0 in the bitmap of pattern 1 is unavailable, and the time slots at other positions are available; the bitmap of pattern 2 indicates that all time slots are available.

Since the current eMBB terminal and the NR Light terminal coexist on the same BWP, the network device determines whether to leave a certain interval for the repeated transmission of the NR Light terminal. At this time, the pattern 1 or pattern can be indicated by 1 bit in the control information. 2. To control whether to set aside resources for the eMBB terminal.

Of course, in practical applications, the length of the bitmap may not be equal to the period of the frame structure, that is, the length of the bitmap is associated with the number of time slots corresponding to the predefined time length. Carrier interval, using 20 time slots as a period to indicate the time slots available for terminal transmission.

If the indication information indicates the transmission interval of repeated transmission, that is, in the case where the indication information indicates the transmission interval of repeated transmission, the indication information includes one of the following:

The number of time slots in the same direction between adjacent time slots used for repeated transmission;

The length of time between adjacent time slots used for repeated transmission.

Among them, the number of time slots in the same direction between adjacent time slots used for repeated transmission can be understood as the interval between adjacent time slots in the same transmission direction used for repeated transmission, that is, the number of consecutive transmissions in repeated transmission. The time slot interval between.

Considering that in the TDD configuration, both uplink and downlink transmission time slots may be discontinuous, therefore, in the embodiment of the present application, the adjacent time slots used for repeated transmission refer to: two consecutive times for repeated transmission The two time slots of transmission, and the adjacent time slots used in the repeated transmission are not necessarily adjacent on absolute time slots, that is, the number of time slots is not necessarily continuous.

Exemplarily, as shown in Figure 2, suppose that the physical downlink control channel (PDCCH) is scheduled to repeat the physical uplink shared channel (PUSCH) 8 times, if the consecutive time slots available for uplink transmission on the time slot number are used for repeated transmission , The number of time slots in the same direction between adjacent time slots used for repeated transmission is 0. If every other available uplink time slot on the time slot number is used for repeated transmission, then the adjacent time slots used for repeated transmission The number of slots in the same direction between slots is 1. In Figure 2, K2 represents the time slot interval from PDCCH to PUSCH.

For example, when the eMBB terminal and the NR Light terminal coexist on the current BWP, the network device can dynamically indicate that the number of time slots in the same direction between adjacent time slots used for repeated transmission is 1, which means scheduling When determining the repeated transmission time slot used by the repeated transmission, one available transmission time slot is used as the time slot resource for repeated transmission every interval.

When there is no need to reserve resources for the eMBB terminal on the current BWP, the network device can dynamically indicate that the number of time slots in the same direction between adjacent time slots used for repeated transmission is 0, which means that after the repeated transmission is scheduled , The available uplink time slot from the start time slot is regarded as the resource for repeated transmission.

That is to say, the network device can set the repetitive transmission interval according to the coexistence of the eMBB terminal and the NR Light terminal on the same BWP (which can be understood as the same time domain resource), and according to the situation of the eMBB terminal. When the terminal is on the same time-frequency resource and cannot dynamically switch the time-domain resource, according to the situation that the terminal cannot dynamically switch the time-domain resource, set the number of time slots in the same direction between adjacent time slots used for repeated transmission. number.

As can be seen from the above description, after scheduling repeated N (N is an integer greater than or equal to 2) transmissions, starting from the starting position of the scheduling, each time an available uplink time slot is encountered (the main considerations are: TDD time slots are not continuous. In some scenarios, the downlink time slot D cannot participate in the uplink repeated transmission, or in other scenarios, the downlink time slot D and the special time slot S cannot participate in the uplink repeated transmission). Whether to repeat the transmission at intervals of M (an integer greater than or equal to 0) can be dynamically indicated by the control information.

It should be noted that if there is a time slot n (a special time slot S) between two uplink time slots, it can include both downlink transmission and uplink transmission. That is, time slot n can be used for both uplink transmission and For downlink transmission, but the uplink transmission part is not enough to carry a certain transmission of repeated transmission, this time slot n is not counted in the interval, and only the time slot capable of carrying repeated transmissions will be counted in the interval. For example, in Figure 1, special The time slot S cannot participate in the uplink repeated transmission, so when calculating the interval, the special time slot S will not be calculated in the interval.

The indication information includes the length of time between adjacent time slots used for repeated transmission, which can be understood as: the length of time between adjacent time slots in the same transmission direction used for repeated transmission, which can specifically refer to: participating in repeated transmission The number of ms of the downlink time slot interval or the number of ms of the uplink time slot interval involved in repeated transmission.

In practical applications, at least two ms number values, such as 0 ms and 5 ms, can be predefined to the terminal through high-level signaling, and the number of ms values selected by the terminal can be dynamically indicated through control information.

Based on this, in an embodiment, when the indication information includes the length of time between adjacent time slots used for repeated transmission, and the indication information is sent to the terminal through control information, the method may also include:

A time length is selected from a plurality of time lengths predefined or configured by the network as the time length of the interval between adjacent time slots used for the repeated transmission.

That is, the time length of the adjacent time slot interval used for the repeated transmission is a time length selected from a plurality of time lengths that are predefined or configured by the network.

Exemplarily, as shown in Figure 3, assuming that PUSCH is repeated 8 times through PDCCH scheduling, if the consecutive time slots available for uplink transmission on the time slot number are used for repeated transmission, the adjacent time slot interval used for repeated transmission The time length of is 0ms. If every other available uplink time slot on the time slot number is used for repeated transmission, the time length of the interval between adjacent time slots used for repeated transmission is 5ms. In Figure 3, K2 represents the slot interval from PDCCH to PUSCH.

That is to say, the network device can set the repetitive transmission interval according to the coexistence of the eMBB terminal and the NR Light terminal on the same BWP (which can be understood as the same time domain resource), and according to the situation of the eMBB terminal. When the terminal is on the same time-frequency resource and cannot dynamically switch the time-domain resource, according to the situation that the terminal cannot dynamically switch the time-domain resource, the time length of the adjacent time slot interval used for repeated transmission is set.

In practical applications, the value of the ms number can also be predefined to match semi-statically, and a bit in the control information is used to indicate whether the value of the ms number is valid.

Based on this, in an embodiment, the time length of the adjacent time slot interval used for the repeated transmission matches the period of the TDD configuration.

Correspondingly, the embodiment of the present application also provides an information transmission method, which is applied to a terminal. As shown in FIG. 4, the method includes:

Step 401: Receive instruction information;

Here, the instruction information indicates one of the following:

Time slots available for repeated transmission;

The transmission interval for repeated transmissions.

Step 402: Use the indication information to determine a time domain resource for repeated transmission.

Wherein, in an embodiment, in step 401, the instruction information is received in one of the following ways:

Receiving the indication information through high-layer signaling;

The instruction information is received through control information.

Specifically, when the network device sends the instruction information through high-level signaling, the terminal receives the instruction information through high-level signaling; when the network device sends the instruction information through control information, the terminal The instruction information is received through control information.

In an embodiment, when the indication information indicates a time slot or subframe pattern used to determine a time slot that can be used for repeated transmission, that is, the indication information indicates the time slot or subframe pattern that can be used for repeated transmission. In the time slot, the network device can configure at least one time slot or subframe pattern for the terminal through the bitmap. At this time, the time slot or subframe pattern indicated by the indication information is from the configured at least one time slot or subframe pattern. A time slot or subframe pattern selected in the pattern.

In other words, the terminal receives at least one time slot or subframe pattern configured by the bitmap on the network side; the indication information indicates the time slot or subframe pattern selected from the configured at least one time slot or subframe pattern.

The embodiment of the present application provides an information transmission method. As shown in FIG. 5, the method includes:

Step 501: The network device sends instruction information to the terminal;

The instruction information indicates one of the following:

Time slots available for repeated transmission;

Step 502: The terminal receives the indication information, and determines a time domain resource for repeated transmission based on the indication information.

It should be noted that the specific processing procedures of the network equipment and the terminal have been described in detail above, and will not be repeated here.

In the information transmission method provided by the embodiment of the application, a network device sends instruction information to a terminal; the instruction information indicates one of the following: a time slot that can be used for repeated transmission; a transmission interval for repeated transmission. Since the instruction information is sent to the terminal, The terminal can determine the time domain resource for repeated transmission according to the instruction information. In this way, when different types of terminals coexist, the transmission efficiency of different terminals can be taken into account. For example, when the NR Light terminal and the eMBB terminal coexist, both The transmission efficiency of the NR Light terminal and the impact on the eMBB terminal avoid the reduction of the eMBB transmission efficiency due to the existence of the NR Light terminal.
