Description

Data transmission method, terminal and base station

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a data transmission method, a terminal, and a base station.

Background

Compared with the existing communication system, the future 5G mobile communication system needs to adapt to more diversified scenes and service requirements. The main scenes of the 5G include enhanced mobile broadband (eMBB), ultra-high reliable ultra-low latency communication (URLLC), and massive machine type communication (mtc), and these scenes impose requirements on the system for high reliability, low latency, large bandwidth, wide coverage, and the like. For a user equipment (UE, also called a terminal), services with different numerical configurations (numerology) may be supported, for example, the UE supports both a URLLC low latency high reliability service and an eMBB service with large capacity and high rate, and may receive a downlink control channel, a downlink data channel, an uplink control channel, and an uplink data channel with two or more numerical configurations at the same time. In Long Term Evolution (LTE), the uplink is single carrier frequency division multiple access (SC-FDMA), and in order to maintain uplink single carrier characteristics, when one subframe is transmitted with both a Physical Uplink Control Channel (PUCCH) and a Physical Uplink Shared Channel (PUSCH), Uplink Control Information (UCI) is transmitted using the PUSCH. Due to the waveform of orthogonal frequency division multiplexing multiple access (DFT-s-OFDM) supporting discrete fourier transform spread spectrum in the new air interface (NR), if a plurality of uplink control (data) channels are transmitted simultaneously, the single carrier characteristic of the UE is damaged, and for this situation, it is considered as a conflict, and a corresponding conflict solution needs to be designed.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1, an embodiment of the present invention provides a data transmission method applied to a terminal, including:

step 101, when a Physical Uplink Control Channel (PUCCH) of a first service is different from a PUCCH of a second service in frequency domain and same in time domain, preferentially transmitting Uplink Control Information (UCI) carried by the PUCCH of the first service to a base station.

It should be noted that the first service is a service occupying fewer Orthogonal Frequency Division Multiplexing (OFDM) symbols, for example, the first service is an ultra-high reliable ultra-low latency communication (URLLC) service; the second service is a service occupying more OFDM symbols, for example, the second service is an enhanced mobile broadband (eMBB) service, and in this embodiment, it is mainly said that when a PUCCH of the URLLC service and a PUCCH of the eMBB service have different frequency domains and the same time domain (that is, a transmission time domain of the PUCCH of the URLLC service overlaps a transmission time domain of the PUCCH of the eMBB service, and at this time, it is considered that two services collide), the PUCCH of the URLLC service is preferentially transmitted, so as to ensure a delay requirement of the URLLC service.

As shown in fig. 2, fig. 2 shows that the PUCCH of the URLLC service is different from the PUCCH of the eMBB service in the frequency domain, and is partially the same in the time domain, and the PUCCH of the URLLC service occupies an OFDM symbol length of 1 eMBB or less in the time domain.

Further, a specific implementation manner of the step 101 is as follows:

and preferentially transmitting the UCI of the first service to the base station through PUCCH resources scheduled by the base station for the terminal.

It should be noted that, the base station may separately allocate a PUCCH resource to the terminal, where the PUCCH resource carries UCI of at least one service.

The following two specific implementation cases exist in step 101 according to the PUCCH resource allocation method.

The method comprises the steps that firstly, a first PUCCH resource of a first service scheduled by a base station for a terminal is obtained, and the first PUCCH resource is scheduled by the base station according to service information of the terminal; and preferentially transmitting UCI of the first service to a base station by utilizing the first PUCCH resource.

It should be noted that, for a terminal configured with a PUCCH for simultaneously transmitting a URLLC service and a PUCCH for an eMBB service, since the base station knows scheduling information of the services of the terminal, the base station allocates a single PUCCH resource for the URLLC service to the terminal, and when the PUCCHs of the two services collide, the terminal uses the PUCCH resource to carry UCI for the URLLC service and UCI for the eMBB service. In this case, when it is known that the terminal simultaneously transmits the PUCCH for the URLLC service and the PUCCH for the eMBB service, the base station dynamically allocates PUCCH resources to the terminal before the terminal transmits the PUCCH for the URLLC service and the PUCCH for the eMBB service, notifies the terminal of the PUCCH resources, and transmits UCI for the URLLC service and UCI for the eMBB service using the PUCCH resources.

Specifically, the implementation manner when the UCI of the first service is preferentially transmitted to the base station by using the first PUCCH resource is as follows: receiving transmission indication information sent by a base station; if the transmission indication information indicates that the terminal carries out service combination transmission, combining the UCI of the first service and the UCI of the second service, and transmitting the combined UCI and the UCI to a base station through the first PUCCH resource; and if the transmission indication information does not indicate the terminal to carry out service combination transmission, transmitting the UCI of the first service to a base station through the first PUCCH resource.

It should be noted that the base station may be configured to transmit only UCI of the URLLC service or transmit UCI of both the URLLC service and the eMBB service when the PUCCH of the URLLC service conflicts with the PUCCH of the eMBB service; the transmission indication information may be included in Downlink Control Information (DCI) of the first service or DCI of the second service sent by the base station, and usually 1bit is used to indicate whether to perform combining transmission. When the base station configures the terminal to transmit UCI of both URLLC service and eMBB service, UCI of both services needs to be merged, and the specific merging manner is: merging the UCI of the first service and the UCI of the second service according to a preset rule; wherein the preset rule comprises: the method includes one of sorting UCIs of different services according to priorities of the services (e.g., arranging UCI of URLLC service in front of the combined overall UCI, or arranging UCI of eMBB service in front of the combined overall UCI) and sorting UCI of different services according to priorities of the UCI (e.g., according to Acknowledgement Characters (ACKs), channel state information reference signal resource indexes (CSI-RS resource indexes), Rank Indication (RI), Channel Quality Indication (CQI), Precoding Matrix Indication (PMI), etc.).

It should be further noted here that, for example, the URLLC service has PUCCH resource a, and the eMBB service has PUCCH resource B; when PUCCH resource A conflicts with PUCCH resource B, if the base station indicates the combined transmission, the base station schedules PUCCH resource C (different from the above PUCCH resource A because of the combined transmission) for carrying out the combined transmission of UCI of URLLC service and eMBB service; and if the combined transmission is not indicated, scheduling one PUCCH resource A, and only transmitting the URLLC service by the terminal at the moment. But from the terminal perspective, the terminal only (sees) receive 1 resource (i.e., PUCCH resource a, or PUCCH resource C) at that time.

Acquiring a second PUCCH resource configured for the terminal by the base station, wherein the second PUCCH resource is periodically configured for the terminal by the base station; and combining the UCI of the first service and the UCI of the second service, and transmitting the combined UCI and UCI of the second service to a base station through the second PUCCH resource.

In this case, the second PUCCH resource is periodically configured for the terminal, and a behavior of the terminal side needs to be agreed, when the PUCCH of the URLLC service of the terminal does not collide with the PUCCH of the eMBB service, the terminal performs transmission of the PUCCHs of the two services according to an existing method, and when the PUCCH of the URLLC service of the terminal collides with the PUCCH of the eMBB service, the terminal uses the second PUCCH resource configured by the base station to combine UCI for transmission of the two services.

The merging method in case two may adopt the same merging method as in case one, and will not be described herein again.

It should be noted that, the two implementation cases mentioned above not only ensure the delay requirement and single carrier characteristic of URLLC service, but also reduce the influence on eMBB service.

Further, another specific implementation manner of the step 101 is as follows:

and discarding the PUCCH of the second service, and transmitting the UCI of the first service to a base station.

It should be noted that, when the PUCCH of the URLLC service conflicts with the PUCCH of the eMBB service, the terminal selects to discard the PUCCH of the eMBB service, only transmits UCI of the URLLC service to the base station, and the corresponding base station only receives UCI of the URLLC service when receiving.

It should be further noted that, if the delay of the URLLC service allows, UCI of the URLLC service may also be merged into the PUCCH of the eMBB for transmission.

It should be noted that what kind of transmission mode is specifically selected can be selected according to the specific application condition to meet the actual use requirement.

In the embodiment of the invention, when the PUCCH of the URLLC service and the PUCCH of the eMBB service have different frequency domains and the same time domains, the UCI carried by the PUCCH of the URLLC service is preferentially transmitted to the base station, so that the transmission delay requirement of the URLLC service is ensured, and the reliability of network communication is ensured.

As shown in fig. 3, an embodiment of the present invention provides a data transmission method applied to a base station, including:

step 301, when a physical uplink control channel PUCCH of a first service is different from a PUCCH of a second service in frequency domain and the time domain is the same, receiving uplink control information UCI carried by the PUCCH of the first service, which is preferentially transmitted by a terminal.

Specifically, one implementation manner of step 301 is:

and the receiving terminal preferentially transmits the UCI of the first service through the scheduled PUCCH resources.

Optionally, the step of the receiving terminal preferentially transmitting the UCI of the first service through the scheduled PUCCH resource includes:

acquiring service information of a terminal;

periodically configuring a second PUCCH resource for the terminal;

notifying the terminal of the second PUCCH resource;

Specifically, another implementation manner of step 301 is:

receiving UCI of the first service transmitted by a terminal;

and the UCI of the first service is transmitted to the base station after the terminal discards the PUCCH of the second service.

It should be noted that all the descriptions on the base station side in the above embodiments are applicable to the base station to which the data transmission method is applied, and the same technical effects can be achieved.
