Technical field

The present disclosure relates to transmission of uplink control data, and in particular, to a data transmission indication method, apparatus, data transmission method, apparatus and device.

Background technique

In a mobile communication system, a mobile communication terminal often transmits various types of data to the network side to facilitate scheduling and planning on the network side. In the related art, the to-be-reported information is usually performed in one TTI (Transmission Time Interval).

For a mobile communication system, the uplink data transmission capability of a mobile communication terminal within a TTI depends on two factors: the duration of the TTI and the frequency domain bandwidth. If the demand for data transmission within a TTI is the same, when the duration of the TTI is reduced (such as uRLLC (Ultra Reliable & Low Latency Communication) services require ultra-high transmission reliability and lower Delayed data transmission, which may require fast scheduling and transmission in the time domain with very short transmission time intervals), the mobile communication terminal needs to occupy a wider bandwidth in the frequency domain. While the duration of the TTI remains the same, but the demand for data transmission within a TTI increases, the mobile communication terminal also needs to occupy a wider bandwidth in the frequency domain.

Taking the uplink control channel in the LTE (Long Term Evolution) system as an example, the uplink control channel in the related art occupies 14 OFDM (Orthogonal Frequency Division Multiplexing) symbols in the time domain. It occupies 12 subcarriers in the frequency domain. When the duration of the TTI is shortened, for example, the TTI is shortened to occupy 2 OFDM symbols in the time domain, and the total number of transmission resources is guaranteed to be the same, the frequency domain needs to occupy 84 subcarriers.

In the related art, the transmission power of the mobile communication terminal is limited, and based on the above requirements, when the mobile communication terminal performs data transmission on a wider bandwidth, its power spectral density (unit bandwidth) The transmission power on the antenna is reduced, which in turn leads to a decrease in the reliability of the transmission.

The above is only an example of the uplink control channel. It should be understood that other types of uplink data transmission also have the same problem.

detailed description

The technical solutions in the embodiments of the present disclosure will be clearly and completely described in the following description of the embodiments of the present disclosure. The embodiments are a part of the embodiments of the present disclosure, and not all of them. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present disclosure without departing from the inventive scope are the scope of the disclosure.

In the data transmission indication method, apparatus, data transmission method, apparatus and device of the embodiments of the present disclosure, the network side determines in real time the target time length required for the mobile communication terminal to transmit the uplink to-be-transmitted data in the time domain, and notifies the mobile communication terminal The data transmission is performed by the mobile communication terminal on the time domain resource of the currently determined target time length, thereby avoiding the problem that the transmission reliability of the mobile communication terminal is reduced due to data transmission over a wide bandwidth.

The data transmission indication method of at least one embodiment of the present disclosure is used on the network side, as shown in FIG. 1 , and includes:

Step 101: Determine a target required by the mobile communication terminal to transmit uplink data to be transmitted in the time domain. length of time;

Step 102: Transmit the target time length to the mobile communication terminal, and instruct the mobile communication terminal to transmit the uplink data to be transmitted by using part or all of the uplink resources in the target time domain resource whose time length is the target time length. Go to the network side.

In a specific embodiment of the present disclosure, the unit of the target time length may adopt a basic time scheduling unit in the time domain, such as TTI in the LTE system in the related art, and may use a minimum time scheduling unit (OFDM symbol) or other ratio. The TTI is described by a larger or smaller time domain unit, but the specific embodiments of the present disclosure are not limited thereto.

That is to say, the target time length may be obtained by counting the number of basic time scheduling units such as TTI or minimum time scheduling unit such as OFDM symbols, such as 3TTI, or 3 OFDM symbols.

In the specific embodiment of the present disclosure, the foregoing uplink to-be-transmitted data may be uplink control information.

In the LTE system, the UE (User Equipment) needs to send the necessary uplink L1/L2 control information to support uplink and downlink data transmission. If the mobile communication terminal is not allocated an uplink resource for the UL-SCH (Uplink-Shared Channel) transmission, the uplink control information of the L1/L2 layer passes the PUCCH (Physical Uplink Control Channel). transmission. In future communication systems, the channel name may change.

The above uplink control information includes but is not limited to the following information:

The SR (Scheduling Request) is used to request an uplink resource from the network side.

HARQ (Hybrid Automatic Repeat ReQuest), which confirms downlink data transmitted on a PDSCH (Physical Downlink Shared Channel);

CSI (Channel State Information), including CQI (Channel Quality Indicator), RI (Rank Indicator), and PMI (Precoding Matrix Indicator), etc., are used to inform the network side. Downstream channel quality to help the network side perform downlink scheduling.

In the related art, the uplink control information is transmitted in one TTI, and when the duration of the TTI is short, the transmission of the uplink control information needs to occupy a wider bandwidth, thereby reducing the reliability of the transmission.

In the embodiment of the present disclosure, the related art is different from the foregoing uplink control information. The duration of the transmission is no longer fixed, but the network side determines its transmission duration according to various parameters (which will be described later) to improve the reliability of the transmission.

An example of this is as follows.

Taking the uplink control channel in the LTE system as an example, the uplink control channel in the related art occupies 14 OFDM (Orthogonal Frequency Division Multiplexing) symbols in the time domain, and occupies 12 subcarriers in the frequency domain.

When the duration of the TTI is shortened, for example, when the TTI is shortened to occupy 2 OFDM symbols in the time domain, if the total number of transmission resources is the same, the frequency domain needs to occupy 84 subcarriers, or the data amount of the uplink control information increases. At 7 times, even if the duration of the TTI does not change, 84 subcarriers are required in the frequency domain.

Taking the duration of the TTI shortened to occupy 2 OFDM symbols as an example, the method of the embodiment of the present disclosure can be used to set the target time length required for the mobile communication terminal to transmit uplink control information in the time domain is 4/8/12/. For OFDM symbols (ie 2/4/6 TTIs), only 42/21/14/... subcarriers are required in the frequency domain. With respect to the related art, it is necessary to occupy 84 subcarriers in the frequency domain, and the method of the embodiment of the present disclosure is used to reduce the bandwidth utilized by the mobile communication terminal for data transmission, and thus the transmission reliability can be improved.

Similarly, when the amount of data of the uplink control information is increased, the method of the embodiment of the present disclosure is adopted, and since the transmission duration of the uplink control information in the time domain can be expanded, the bandwidth used by the mobile communication terminal for data transmission can be reduced. Improve transmission reliability.

In a specific embodiment of the present disclosure, it is required to determine a target time length required for the mobile communication terminal to transmit uplink to-be-transmitted data in the time domain, and determining the target time length may be determined according to various parameters, as described below.

<Mode 1>

In the first method, the target time length is determined according to the maximum transmit power of the mobile communication terminal. After determining the minimum power spectral density that satisfies the reliability requirement, if the maximum transmit power of the mobile communication terminal is large, the mobile communication terminal may Data transmission is performed on a wider bandwidth. Conversely, the mobile communication terminal can only transmit data on a narrower bandwidth.

When the amount of data of the uplink control information to be transmitted is constant, the bandwidth in the frequency domain is inversely proportional to the duration in the time domain.

Therefore, in the first method, the larger the maximum transmission power of the mobile communication terminal, the shorter the target time length, and conversely, the longer the target time length.

<Method 2>

In a specific embodiment of the present disclosure, the purpose of determining the target time length described above is to improve the reliability of data transmission.

From the coverage performance of the mobile communication network, the better the coverage performance, the higher the reliability, and the worse the coverage performance, the lower the reliability.

Therefore, in the second method, the target time length is determined according to the uplink transmission quality of the mobile communication terminal, and the uplink transmission quality of the mobile communication terminal (which can be reflected by parameters such as the uplink signal-to-noise ratio) is better. The shorter the target time length, on the other hand, the longer the target time length.

This is further explained below.

For a mobile communication terminal with better coverage (such as a mobile communication terminal at the center of the cell), the transmission of the uplink control channel may satisfy the reliability requirement through an uplink resource within a TTI. For a mobile communication terminal with poor coverage performance (such as a mobile communication terminal at the cell edge), the uplink coverage performance is poor, and the uplink resource joint transmission in multiple TTIs is required to meet the reliability requirement.

Of course, the target time length can also be determined according to the service delay requirement. When the service delay requirement is high, the target time length should be shorter, and vice versa.

In a specific embodiment of the present disclosure, in the time domain, the TTI in the above TTI may be as shown in FIG. 2a-2c, where:

The TTI in Figure 2a includes downlink resources, uplink resources, and interval (GP (Guard Period)) resources;

In Figure 2b, the continuously distributed basic time scheduling unit (TTI) includes both an uplink basic time scheduling unit and a downlink basic time scheduling unit, such as a TTI in a TDD system;

In Figure 2c, only the uplink resources, such as the TTI in the FDD (Frequency Division Duplex) system, are included in the continuously distributed TTI.

In a specific embodiment of the present disclosure, the target time domain resource is composed of at least one basic time scheduling unit, and each of the at least one basic time scheduling unit has a basic time scheduling unit that can be used to transmit the uplink waiting area. Transmitting uplink resources of data, and in the time domain, the at least There is no basic time unit between any adjacent basic time scheduling units in a basic time scheduling unit that can be used to transmit uplink data to be transmitted.

Taking FIG. 2b as an example, in the specific embodiment of the present disclosure, the target time domain resources of the three basic time scheduling units are composed of the basic time scheduling units No. 1, 2, and 5.

Certainly, in a specific embodiment of the present disclosure, the target time domain resource may also be composed of a minimum time scheduling unit, where the minimum time scheduling unit is an uplink resource that can be used for transmitting uplink data to be transmitted, and in the time domain, There is no minimum time scheduling unit between any adjacent minimum time scheduling units in the at least one minimum time scheduling unit that can be used to transmit the uplink data to be transmitted.

Certainly, in the specific embodiment of the present disclosure, all uplink resources in the target time domain resource may be used for transmission of uplink data to be transmitted (such as an uplink control channel), but only some of the resources may be used to schedule the unit. Explain the following for TTI.

The uplink resource used to form the uplink control channel transmission resource in a certain TTI may be the duration of all the uplink resources in the TTI occupied by the time domain, or may be the duration of the partial uplink resources in the TTI occupied by the time domain. For example, for a certain TTI, the uplink resource transmission part is composed of N OFDM symbols, and the resources in the TTI for transmitting the uplink control channel may occupy all N OFDM symbols in the time domain, and may also occupy part of the OFDM symbols, such as N/2 OFDM symbols, and even in some cases, the number of OFDM symbols allowed for control channel transmission is greater than N (eg, some GP resources in TDD are used to transmit the uplink control channel). When the uplink coverage performance is good, the transmission of the uplink control channel may only need to occupy part of the uplink OFDM symbol transmission within one TTI to achieve the required demodulation performance.

In a specific embodiment of the present disclosure, the target time length determined by the network side and various policies need to notify the mobile communication terminal, so that the mobile communication terminal can transmit the above uplink in the time domain resource whose time length is the target time length. Control information. The target time length determined by the network side and the manner in which the processing policy notifies the mobile communication terminal are various, such as:

Through high-level signaling, such as RRC (Radio Resource Control) signaling; or

The time length of the time domain resource used by the uplink feedback channel corresponding to the downlink data scheduling is simultaneously indicated by the real-time control signaling transmission, such as in the downlink control channel for scheduling the downlink data transmission.

Of course, the embodiments of the present disclosure can also be combined with high-level signaling and real-time control signaling. If the high-level signaling informs the target time length, the mobile communication terminal will monitor the dynamic signaling at the same time. After receiving the dynamic signaling notification, it will transmit the uplink control channel according to the target time length of the dynamic notification within its validity period. Otherwise, The target time length of the high layer signaling is transmitted.

In a specific embodiment of the present disclosure, when multiple TTIs are used to transmit data, the following may occur:

The number of basic time scheduling units in the target time domain resource is greater than or equal to 2;

When a basic time scheduling unit in the target time domain resource needs to transmit different uplink data to be transmitted

In the specific embodiment of the present disclosure, for the first case, the method further includes:

Transmitting a first data processing policy to the mobile communication terminal, instructing the mobile communication terminal to transmit the uplink to be transmitted according to the first processing policy when the number of basic time scheduling units in the target time domain resource is greater than or equal to data.

The first data processing policy can be:

Retransmitting the uplink to-be-transmitted data to the network side by using uplink resources in each basic time scheduling unit in the target time domain resource; or

Pre-processing the uplink data to be transmitted, obtaining intermediate data, and transmitting the first intermediate data to the network side by using a target time domain resource, where the network side uses the first intermediate data to obtain the Uplink data to be transmitted.

For the second case mentioned above, it also includes:

Transmitting a second data processing policy to the mobile communication terminal, instructing the mobile communication terminal to transmit according to the second processing policy when a basic time scheduling unit in the target time domain resource needs to transmit different uplink to-be-transmitted data The uplink data to be transmitted is described.

The second data processing strategy is:

Allocating different uplink control channels for different uplink to be transmitted data in the basic time scheduling unit; or

Transmitting, by using an uplink control channel, a second intermediate data generated according to the different uplink to-be-transmitted data to the network side, and using the second intermediate data to restore the difference Uplink data to be transmitted.

These strategies will be described in detail on the terminal side.

The data transmission method of the embodiment of the present disclosure is used in a mobile communication terminal, as shown in FIG. 3, and includes:

Step 301: Receive a target time length required by the mobile communication terminal that is determined and sent by the network to transmit uplink data to be transmitted in the time domain.

Step 302: Transmit the uplink to-be-transmitted data to the network side by using part or all of the uplink resources in the target time domain resource whose time length is the target time length.

In the embodiment of the present disclosure, the difference from the related art is that the duration of the uplink control information transmitted by the mobile communication terminal in the time domain is not fixed, but is determined by the network side according to various parameters as described above. Improve the reliability of data transmission.

Further, in the above data transmission method, the uplink to-be-transmitted data is uplink control information.

Further, in the above data transmission method, the time length is determined according to a maximum transmission power and/or an uplink transmission quality and/or a service delay requirement of the mobile communication terminal.

Further, in the above data transmission method, the target time length is transmitted through high layer signaling and/or real time control signaling.

Further, in the above data transmission method, the real-time control signaling is transmitted through a downlink control channel.

In a specific embodiment of the present disclosure, the mobile communication terminal determined and transmitted by the network side transmits a target time length required for uplink data to be transmitted in the time domain, where the target time length includes the following two cases:

The target time length is 1 basic time scheduling unit (TTI in the current LTE system, but not limited to TTI);

The target time length is greater than or equal to 2 basic time scheduling units.

The first case is the same as the related art and will not be described in detail here.

For the second case, the basic time scheduling unit is a TTI. The time domain resource includes multiple TTIs. Therefore, how the uplink data to be transmitted is transmitted through multiple TTIs.

In a specific embodiment of the present disclosure, when the number of basic time scheduling units in the target time domain resource is greater than or equal to 2, some or all uplink resource transmission stations in the target time domain resource whose time length is the target time length are utilized. The manner in which the uplink data to be transmitted is transmitted to the network side includes multiple types. Explain as follows.

<Mode 1>

In the first mode, when the number of basic time scheduling units in the target time domain resource is greater than or equal to 2, the uplink data to be transmitted is repeatedly transmitted to the uplink resource in each basic time scheduling unit in the target time domain resource. Said network side.

The above line control information is illustrated as follows.

As shown in the following table, the transmission of data d0 is distributed in TTI #0. It is assumed that for the current mobile communication terminal, the time domain resource for the uplink control information determined by the method of the present disclosure is 3 TTIs, and the data processing delay of the UE is 1 TTI, and then the transmission is performed in TTI #0. D0, its uplink feedback is transmitted in TTI #2, 3 and 4, wherein the information transmitted in the last two TTIs and the format of the transmission are completely duplicates of the feedback information B transmitted in the first TTI.

TTI#0	TTI#1	TTI#2	TTI#3	TTI#4
D0		B	B	B

In the above manner, the design of the uplink control channel is relatively simple, and only the design of the uplink control channel for the uplink resource in a single TTI needs to be performed.

At the same time, the above uplink control information realizes multiple repeated transmissions, which improves the reliability of data transmission.

<Method 2>

It can be found that, in the specific embodiment of the present disclosure, the data that needs to be transmitted is B, and when there are multiple basic time scheduling units that can be used to transmit uplink control information, the specific embodiment of the present disclosure may also be used for uplink transmission. Performing a pre-processing on the data to obtain the first intermediate data, and then transmitting the first intermediate data to the network side by using the target time domain resource, and using the first intermediate data to restore the uplink to be transmitted by the network side data.

That is to say, in the second method, the above-mentioned time domain resources are combined as a unified transmission resource, and then the transmission processing is performed.

In the second method, the foregoing preprocessing is a process capable of improving data transmission reliability, such as encoding, modulation, and spreading, which can improve the reliability of data transmission. However, the specific embodiments of the present disclosure are not limited to improve data transmission. The specific operation of reliability.

An example is as follows.

As shown in the following table, the transmission of data d0 is distributed in TTI #0. It is assumed that for the current mobile communication terminal, the time domain resource for the uplink control information determined by the method of the present disclosure is 3 TTIs, and the data processing delay of the UE is 1 TTI, and then the transmission is performed in TTI #0. D0, its uplink feedback is transmitted in TTI #2, 3 and 4, and if the original control information to be transmitted is B, then B is preprocessed (such as encoding, modulation, spread spectrum) to obtain B ¹ B ² B ³ , B ¹ , B ² and B ³ are transmitted in TTI #2, 3 and 4, respectively.

TTI#0	TTI#1	TTI#2	TTI#3	TTI#4
D0		B 1	B 2	B 3

In the above manner, the design of the uplink control channel is relatively complicated, but the reliability of data transmission is improved by preprocessing (such as coding, modulation, and spreading).

The above describes a processing method of an embodiment of the present disclosure when the same information is transmitted using different TTIs.

However, in the specific embodiment of the present disclosure, the same applies to the case where a plurality of data to be transmitted corresponding to different uplink control information needs to be transmitted in the same basic time scheduling unit, which is exemplified as follows.

As shown in the following table, the transmission of data d0 and d1 is distributed in TTI #0 and TTI #1. It is assumed that for the current mobile communication terminal, the time domain resource for the uplink control information determined by the method of the present disclosure is 3 TTIs, and the data processing delay of the UE is 1 TTI, and then the transmission is performed in TTI #0. D0, whose uplink feedback B is transmitted in TTI #2, 3, and 4 (as mentioned above, the transmission may be B, B, and B, or may be B ¹ , B ^{2 ,} and B ³ ), but for TTI# The d1 transmitted in 1 has its uplink feedback transmitted in TTI #3, 4 and 5 (as mentioned above, the transmission may be C, C and C, and may also be C ¹ , C ² and C ³ ).

TTI#0	TTI#1	TTI#2	TTI#3	TTI#4	TTI#5
D0	D1	B	B, C	B, C	C

Therefore, it can be found that in TTI #3 and 4, the data to be transmitted corresponds to different uplink control information (B and C). In this manner, the specific embodiment of the present disclosure can be in a TTI in various ways. The data corresponding to the different uplink control information (the uplink control information itself or a part of the intermediate data obtained based on the uplink control information) is transmitted as follows.

In one mode, when a basic time scheduling unit in the target time domain resource needs to transmit differently When the uplink data to be transmitted is used, the step of using the time length of the target time length to transmit the uplink data to be transmitted to some or all of the uplink resources in the target time domain resource is different in the basic time scheduling unit. The uplink to be transmitted data allocates different uplink control channels.

The above control channel is taken as an example. The above manner is different from the related art. In one TTI, a mobile communication terminal can simultaneously transmit multiple uplink control channels, and perform combined detection of control channels of the same data at the receiving end.

In another mode, when a basic time scheduling unit in the target time domain resource needs to transmit different uplink to-be-transmitted data, the utilization time length is part or all of the uplink time domain resources in the target time domain. In the step of transmitting the uplink data to be transmitted, the second intermediate data generated according to different uplink to-be-transmitted data is transmitted to the network side by using an uplink control channel in the basic time scheduling unit, and the network side uses the network side. The second intermediate data is restored to obtain the different uplink to-be-transmitted data.

In a specific embodiment of the present disclosure, the second intermediate data described above may be generated as follows:

1. Combining a plurality of data to be transmitted corresponding to different uplink control information appearing in the same basic time scheduling unit to obtain one control information, and then transmitting the combined control information in the basic time scheduling unit.

Assuming that three data a0, a1, and a2 need to be transmitted in TTI#4, a0, a1, and a2 each contain two codewords, then the following merge operation can be performed to logically decode the first codeword of a0, a1, and a2. With the operation, the code word A1 is obtained, and the second code word of a0, a1 and a2 is logically ANDed to obtain the code word A2, and the finally obtained intermediate data is A1A2.

2. Jointly encoding a plurality of data to be transmitted corresponding to different uplink control information appearing in the same basic time scheduling unit, obtaining the intermediate data, and transmitting the intermediate data in an uplink control channel.
