Description
Technical Field
The present invention relates to transmission of uplink control data, and in particular, to a data transmission indication method, apparatus, data transmission method, apparatus, and device.
Background
In a mobile communication system, a mobile communication terminal often transmits various types of data to a network side to facilitate scheduling and planning on the network side. In the prior art, the information to be reported is usually performed within one TTI (transmission time Interval).
For a mobile communication system, the uplink data transmission capability of a mobile communication terminal in one TTI depends on two factors: the duration of the TTI and the frequency domain bandwidth. If the requirement for data transmission in one TTI is the same, after the duration of the TTI is reduced (e.g., after the Ultra Reliable and Low Latency Communication (urrllc) service requires Ultra high transmission reliability and lower Latency data transmission, which may require fast scheduling and transmission in the time domain with a short transmission time interval), the mobile Communication terminal needs to occupy a wider bandwidth in the frequency domain. When the duration of a 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 an uplink control channel in an LTE system as an example, an existing uplink control channel occupies 14 OFDM (Orthogonal Frequency Division Multiplexing) symbols in a time domain and 12 subcarriers in a 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, the frequency domain needs to occupy 84 subcarriers under the condition that the total number of transmission resources is the same.
Based on the above requirement, when the mobile communication terminal performs data transmission over a wider bandwidth, its power spectral density (transmission power per unit bandwidth) is reduced, which leads to a reduction in transmission reliability.
Of course, the above description is made by taking the uplink control channel as an example, and it should be understood that the same problem exists in other types of uplink data transmission.

Detailed Description
In the data transmission indicating method, the data transmission indicating device, the data transmission method, the data transmission device and the equipment of the embodiment of the invention, the network side determines the target time length required by the mobile communication terminal for transmitting the uplink data to be transmitted in the time domain in real time, and informs the mobile communication terminal to transmit the data on the time domain resource of the currently determined target time length by the mobile communication terminal, so that the problem of transmission reliability reduction caused by data transmission of the mobile communication terminal in a very wide bandwidth is avoided.
The data transmission indication method according to the first embodiment of the present invention is used in a network side, and as shown in fig. 1, includes:
and 102, transmitting the target time length to the mobile communication terminal, and instructing the mobile communication terminal to transmit the uplink data to be transmitted to the network side by using part or all uplink resources in the target time domain resources with the time length being the target time length.
In this embodiment of the present invention, the unit of the target time length may be a basic time scheduling unit in a time domain, such as a TTI in an existing LTE system, or may be described by using a minimum time scheduling unit (OFDM symbol) or other time domain units that are larger or smaller than the TTI, but this is not limited to this specific embodiment of the present invention.
That is, the target time length may be obtained by counting the number of basic time scheduling units, such as TTIs, or minimum time scheduling units, such as OFDM symbols, etc., such as 3 TTIs, or 3OFDM symbols.
In an embodiment of the present invention, the uplink data to be transmitted may be uplink control information.
In an LTE (Long Term Evolution ) system, a UE needs to send necessary uplink L1/L2 control information to support uplink and downlink data transmission. If the mobile communication terminal is not allocated Uplink resources for UL-SCH (Uplink-shared Channel) transmission, Uplink Control information of the L1/L2 layer is transmitted through a PUCCH (Physical Uplink Control Channel). In future communication systems, the channel name may change.
The uplink control information includes, but is not limited to, the following information:
an SR (Scheduling Request) for requesting an uplink resource to a network side;
HARQ (Hybrid Automatic Repeat reQuest), which confirms Downlink data transmitted on PDSCH (Physical Downlink Shared Channel);
the CSI (Channel State Information) includes CQI (Channel quality Indicator), RI (Rank Indicator), PMI (Precoding matrix Indicator), and the like, and is used to tell the network side about the downlink Channel quality to help the network side perform downlink scheduling.
In the prior art, the uplink control information is transmitted within one TTI, and when the duration of the TTI is short, the transmission of the uplink control information needs to occupy a wider bandwidth, which further reduces the reliability of transmission.
In the embodiment of the present invention, unlike the prior art, the duration of the transmission of the uplink control information is not fixed, but the network side determines the transmission duration according to various parameters (which will be described later), so as to improve the reliability of the transmission.
This is exemplified as follows.
Taking an uplink control channel in an LTE system as an example, an existing uplink control channel occupies 14 OFDM (Orthogonal Frequency Division Multiplexing) symbols in a time domain and 12 subcarriers in a Frequency domain.
After the duration of the TTI is shortened, for example, the TTI is shortened to occupy 2 OFDM symbols in the time domain, it is guaranteed that 84 subcarriers are occupied in the frequency domain under the condition that the total number of transmission resources is the same, or 84 subcarriers are occupied in the frequency domain even if the duration of the TTI is unchanged when the data amount of the uplink control information is increased by 7 times.
Taking the example that the duration of the TTI is shortened to occupy 2 OFDM symbols, by using the method of the embodiment of the present invention, the target time length required by the mobile communication terminal to transmit uplink control information in the time domain can be set to 4/8/12/....... times, OFDM symbols (i.e., 2/4/6 TTIs), and then only 42/21/14/......... times, subcarriers need to be occupied in the frequency domain. Compared with the prior art that 84 subcarriers are occupied in the frequency domain, the method of the embodiment of the invention reduces the bandwidth used by the mobile communication terminal for data transmission, thereby improving the transmission reliability.
Similarly, when the data amount of the uplink control information is increased, the method of the embodiment of the invention can expand the transmission duration of the uplink control information in the time domain, thereby reducing the bandwidth used by the mobile communication terminal for data transmission and improving the transmission reliability.
In the embodiment of the present invention, a target time length required by the mobile communication terminal to transmit uplink data to be transmitted in the time domain needs to be determined, and the determination of the target time length may be determined according to various parameters, which is described below.
< first mode >
In the first mode, the target time length is determined according to the maximum transmission power of the mobile communication terminal, and after the minimum power spectral density meeting the reliability requirement is determined, if the maximum transmission power of the mobile communication terminal is larger, the mobile communication terminal can transmit data on a wider bandwidth, otherwise, the mobile communication terminal can only transmit data on a narrower bandwidth.
And under the condition that the data volume of the uplink control information to be transmitted is certain, the bandwidth in the frequency domain and the duration in the time domain are in inverse proportion.
Therefore, in the first mode, the larger the maximum transmission power of the mobile communication terminal is, the shorter the target time length is, and conversely, the longer the target time length is.
< second mode >
In an embodiment of the present invention, the purpose of determining the target time length is to improve reliability of data transmission.
In terms of coverage performance of the mobile communication network, the better the coverage performance, the higher the reliability thereof, and the worse the coverage performance, the lower the reliability thereof.
Therefore, in the second mode, the target time length is determined according to the uplink transmission quality of the mobile communication terminal, and the target time length is shorter as the uplink transmission quality of the mobile communication terminal (which can be reflected by parameters such as the uplink signal-to-interference-and-noise ratio) is better, and conversely, the target time length is longer.
This is further explained below.
For a mobile communication terminal with better coverage performance (e.g. a mobile communication terminal located in the center of a cell), the transmission of the uplink control channel may satisfy the reliability requirement through the uplink resource within one TTI. For a mobile communication terminal with poor coverage performance (such as a mobile communication terminal located at the edge of a cell), the uplink coverage performance is poor, and uplink resource joint transmission in multiple TTIs is required to meet the reliability requirement.
Of course, the target time length may also be determined according to the service delay requirement, when the service delay requirement is higher, the target time length should be shorter, otherwise, the target time length may be longer.
In an embodiment of the present invention, in the time domain, the TTIs in the TTIs may be TTIs shown in fig. 2a-2c, where:
the TTI in fig. 2a includes downlink resources, uplink resources, and Gap (GP) resources;
in fig. 2b, the continuously distributed basic time scheduling units (TTIs) include both uplink basic time scheduling units and downlink basic time scheduling units, such as TTIs in a TDD system;
in fig. 2c, only uplink resources are included in the continuously distributed TTIs, such as TTIs in FDD systems.
In a specific embodiment of the present invention, the target time domain resource is composed of at least one basic time scheduling unit, each basic time scheduling unit in the at least one basic time scheduling unit has an uplink resource capable of being used for transmitting the uplink data to be transmitted, and in a time domain, there is no basic time unit capable of being used for transmitting the uplink data to be transmitted between any adjacent basic time scheduling units in the at least one basic time scheduling unit.
Taking fig. 2b as an example, in the embodiment of the present invention, the target time domain resources of 3 basic time scheduling units are formed by the number 1, 2, and 5 basic time scheduling units.
Of course, in the specific embodiment of the present invention, the target time domain resource may also be composed of a minimum time scheduling unit, 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 that can be used for transmitting the uplink data to be transmitted between any adjacent minimum time scheduling units in the at least one minimum time scheduling unit.
Of course, in the specific embodiment of the present invention, all uplink resources in the target time domain resource may be used for transmitting uplink data to be transmitted (such as an uplink control channel), but only a part of the resources may be used, and the following description is given by taking the time scheduling unit as a TTI.
The uplink resource used to form the uplink control channel transmission resource in a certain TTI may be the duration of the entire uplink resource in the TTI occupied in the time domain, or may also be the duration of a part of the uplink resource in the TTI occupied in the time domain. For example, for a certain TTI, the uplink resource transmission part is formed by N OFDM symbols, and the resource in the TTI for transmitting the uplink control channel may occupy all N OFDM symbols in the time domain, or may occupy part of the OFDM symbols, such as N/2 OFDM symbols, and even in some cases, the number of OFDM symbols for allowing transmission of the control channel is greater than N (for example, part of GP resources in TDD is used to transmit the uplink control channel). When the uplink coverage performance is better, the transmission of the uplink control channel may only occupy part of the uplink OFDM symbol transmission within 1 TTI to achieve the required demodulation performance.
In the specific embodiment of the present invention, the target time length and various policies determined by the network side need to be notified to the mobile communication terminal, so that the mobile communication terminal can transmit the uplink control information in the time domain resource with the time length being the target time length. The target time length and the processing strategy determined by the network side inform the mobile communication terminal in various ways, such as:
transmitting through a higher layer signaling, such as RRC (Radio Resource Control) signaling; or
Through real-time control signaling transmission, for example, the time length of the time domain resource used by the uplink feedback channel corresponding to the downlink data scheduling is indicated in the downlink control channel for scheduling downlink data transmission at the same time.
Of course, the embodiment of the present invention may also combine the high layer signaling and the real-time control signaling for transmission, such as: the mobile communication terminal will monitor the dynamic signaling notice at the same time, and transmit the uplink control channel according to the target time length of the dynamic notice in the validity period after receiving the dynamic signaling notice, otherwise, transmit according to the target time length of the high-level signaling notice.
In the embodiment of the present invention, when data is transmitted using multiple TTIs, there may be the following situations:
the number of basic time scheduling units in the target time domain resource is greater than or equal to 2; and
when one basic time scheduling unit in the target time domain resource needs to transmit different uplink data to be transmitted
In an embodiment of the present invention, for the first case, the method further includes:
and transmitting a first data processing strategy to the mobile communication terminal, and when the number of basic time scheduling units in the target time domain resource of the mobile communication terminal is indicated to be more than or equal to 2, transmitting the uplink data to be transmitted according to the first processing strategy.
The first data processing policy may be:
repeatedly transmitting the uplink data to be transmitted to the network side by using the uplink resource in each basic time scheduling unit in the target time domain resource; or
Preprocessing the uplink data to be transmitted to obtain intermediate data, transmitting the first intermediate data to the network side by using target time domain resources, and restoring the first intermediate data by the network side to obtain the uplink data to be transmitted.
For the second case, the method further includes:
and transmitting a second data processing strategy to the mobile communication terminal, and indicating the mobile communication terminal to transmit the uplink data to be transmitted according to the second processing strategy when one basic time scheduling unit in the target time domain resource needs to transmit different uplink data to be transmitted.
The second data processing strategy is:
different uplink control channels are distributed for different uplink data to be transmitted in a basic time scheduling unit; or
And transmitting second intermediate data generated according to the different uplink data to be transmitted to the network side by using an uplink control channel in a basic time scheduling unit, and restoring the different uplink data to be transmitted by using the second intermediate data by the network side.
These strategies will be explained in detail on the terminal side.
The data transmission method of the embodiment of the invention is used for a mobile communication terminal, and as shown in fig. 3, the method comprises the following steps:
In the embodiment of the present invention, unlike the prior art, 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 the various parameters, so that the reliability of data transmission can be improved.
In the above data transmission method, the uplink data to be transmitted is uplink control information.
In the above data transmission method, the time length is determined according to the maximum transmission power and/or uplink transmission quality and/or service delay requirement of the mobile communication terminal.
In the above data transmission method, the target time length is transmitted by high layer signaling and/or real-time control signaling.
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 invention, a target time length required by the mobile communication terminal to transmit uplink data to be transmitted in a time domain, which is determined and sent by a network side, is determined, 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); and
the target time length is greater than or equal to 2 basic time scheduling units.
The first case is the same as the prior art and will not be described in detail here.
For the second case, taking the basic time scheduling unit as the TTI as an example, the time domain resource includes a plurality of TTIs, so how to transmit the uplink data to be transmitted through the plurality of TTIs is involved.
In the specific embodiment of the present invention, when the number of the basic time scheduling units in the target time domain resource is greater than or equal to 2, various ways are included for transmitting the uplink data to be transmitted 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, which are described below respectively.
< first mode >
In the first mode, when the number of the basic time scheduling units in the target time domain resource is greater than or equal to 2, the uplink resource in each basic time scheduling unit in the target time domain resource is used for repeatedly transmitting the uplink data to be transmitted to the network side.
The uplink control information is exemplified as follows.
As shown in the table below, the transmission of data d0 is distributed in TTI # 0. Assuming that, for the current mobile communication terminal, the time domain resource for the uplink control information determined by the method of the embodiment of the present invention is 3 TTIs, and the data processing delay of the UE is 1 TTI, for d0 transmitted in TTI #0, uplink feedback is transmitted in TTIs #2, 3, and 4, where the information transmitted in the last two TTIs and the format of the transmission are completely the repetition 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 needs to be performed for the uplink resources in a single TTI.
Meanwhile, the uplink control information realizes repeated transmission for many times, and improves the reliability of data transmission.
< second mode >
It can be found that, in the specific embodiment of the present invention, the data actually required to be transmitted is B, and when there are a plurality of basic time scheduling units that can be used for transmitting the uplink control information, the specific embodiment of the present invention may also perform a preprocessing on the uplink data to be transmitted to obtain first intermediate data, then transmit the first intermediate data to the network side by using the target time domain resource, and obtain the uplink data to be transmitted by the network side by using the first intermediate data through restoration.
That is, in the second embodiment, the transmission processing is performed after the above-described time domain resources are combined to form a unified transmission resource.
In the second embodiment, the preprocessing is a processing capable of improving the reliability of data transmission, such as encoding, modulation, spreading, and the like, but the specific operation capable of improving the reliability of data transmission is not limited in the embodiments of the present invention.
Examples are as follows.
As shown in the table below, the transmission of data d0 is distributed in TTI # 0. Assuming that, for the current mobile communication terminal, the time domain resource for the uplink control information determined by the method of the embodiment of the present invention is 3 TTIs, and the data processing delay of the UE is 1 TTI, for d0 transmitted in TTI #0, the uplink feedback is transmitted in TTIs #2, 3, and 4, and assuming that the original control information to be transmitted is B, the B is preprocessed (e.g., encoded, modulated, and spread) to obtain B1B2B3，B1、B2And B3Transmitted in TTIs #2, 3 and 4, respectively.
In the above manner, the design of the uplink control channel is relatively complex, but the reliability of data transmission is improved by preprocessing (e.g. coding, modulation, and spreading).
The processing method of the embodiment of the present invention when the same information is transmitted using different TTIs is described above.
However, in the specific embodiment of the present invention, the following description also refers to a situation that multiple pieces of data to be transmitted corresponding to different pieces of uplink control information need to be transmitted in the same basic time scheduling unit.
As shown in the following table, the transmission of data d0 and d1 are distributed in TTI #0 and TTI # 1. Assuming that the time domain resource for uplink control information determined by the method of the embodiment of the present invention is 3 TTIs and the data processing delay of the UE is 1 TTI for the current mobile communication terminal, for d0 transmitted in TTI #0, its uplink feedback B is transmitted in TTIs #2, 3 and 4 (as mentioned above, the uplink feedback B may be transmitted in B, B and B, and may also be transmitted in B1、B2And B3) Whereas for d1 transmitted in TTI #1, its uplink feedback is transmitted in TTIs #3, 4 and 5 (as previously mentioned, it may be C, C and C, and also C1、C2And C3)。
| TTI#0 | TTI#1 | TTI#2 | TTI#3 | TTI#4 | TTI#5 |
| d0 | d1 | B | B、C | B、C | C |
Therefore, it can be seen that in TTIs #3 and #4, the data to be transmitted corresponds to different uplink control information (B and C), and in this way, in this embodiment of the present invention, the data corresponding to different uplink control information (the uplink control information itself, or a part of the intermediate data obtained according to the uplink control information) can be transmitted in one TTI in various ways, which is described in detail below.
In one mode, when one basic time scheduling unit in a target time domain resource needs to transmit different uplink data to be transmitted, in the step of transmitting the uplink data to be transmitted by using part or all of the uplink resources in the target time domain resource with the time length being the target time length, different uplink control channels are allocated for the different uplink data to be transmitted in the basic time scheduling unit.
Taking the uplink control channel as an example, the above manner is different from the prior art in that the mobile communication terminal can simultaneously transmit a plurality of uplink control channels in one TTI, and perform merging detection of the control channels of the same data at the receiving end.
In another mode, when one basic time scheduling unit in the target time domain resource needs to transmit different uplink data to be transmitted, in the step of transmitting the uplink data to be transmitted by using part or all of the uplink resources in the target time domain resource with the time length being the target time length, an uplink control channel is used in the basic time scheduling unit to transmit second intermediate data generated according to the different uplink data to be transmitted to the network side, and the network side uses the second intermediate data to restore the different uplink data to be transmitted.
In an embodiment of the present invention, the second intermediate data may be generated as follows:
1. and combining a plurality of data to be transmitted corresponding to different uplink control information in the same basic time scheduling unit to obtain one piece of 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, and each of a0, A1 and a2 includes 2 codewords, a combination operation may be performed, where a first codeword of a0, A1 and a2 is logically anded to obtain codeword A1, a second codeword of a0, A1 and a2 is logically anded to obtain codeword a2, and finally the obtained intermediate data is A1a 2.
2. And jointly encoding a plurality of data to be transmitted corresponding to different uplink control information in the same basic time scheduling unit to obtain the intermediate data, and transmitting the intermediate data in an uplink control channel.
