Description

Uplink signal transmission method, terminal equipment and network equipment

Technical Field

The present invention relates to the field of information processing technologies, and in particular, to an uplink signal transmission method, a terminal device, a network device, a chip, a computer-readable storage medium, a computer program product, and a computer program.

Background

Current 5G (NR, new radio) systems introduce a highly Reliable Low-Latency communication (URLLC) service that is characterized by Ultra-high reliability (e.g., 99.999%) transmissions within an extreme Latency (e.g., 1 ms). To achieve this goal, a Preemption mechanism (Preemption) is introduced in the downlink, that is, a URLLC service is inserted during the transmission of an eMBB (enhanced mobile broadband) service, as shown in fig. 1. Because the eMMC UE does not know to insert the URLLC service, the URLLC data is demodulated as eMMC data, and the demodulation performance of the eMMC data is seriously influenced. However, there is no complete scheme for how to transmit uplink in time, and the uplink preemption mechanism not only ensures priority scheduling of URLLC service, but also ensures that other users (occupying the same time-frequency resource) stop transmitting, thereby avoiding interference between users. Currently, one way is to initiate a new uplink schedule instead of the current one. When the terminal receives a new schedule of the same process, it stops/suspends all/part of the transmissions corresponding to the old schedule and initiates a new transmission according to the new schedule indication, as shown in fig. 2-1. In this manner, the new schedule may indicate partial transmission or may be a full retransmission. The indication unit may be CBG or N symbols (N is a positive integer). When the unit of indication is N symbols, the part that stops transmission does not necessarily contain an integer number of coding block groups CBG (code block group), and there is no solution for how the transmission is resumed by the incomplete CBG. For example, referring to fig. 2-2, in fig. 2-2, when the recovery transmission is performed, the incomplete CBGs 1, 3 are transmitted; modulation coding remains unchanged for transmission, with greater limits on scheduling. If the modulation code is changed, the two transmissions of the same CBG cannot be combined. In fig. 2-3, when the indication unit is CBG, the CBG stopping transmission does not necessarily occupy an integer number of symbols, which results in different frequency domain resources on different symbols.

step 202: stopping transmission based on the indication information and/or resuming transmission based on the indication information.

It should be noted that, resuming transmission may be understood as: initiating retransmission for the case where a data packet is scheduled but not transmitted or not completely transmitted; the scheduling manner for resuming transmission may include new transmission scheduling signaling, retransmission scheduling signaling, and the like, and the scheduling form is not limited, and is not exhaustive in this embodiment.

That is, when the transmission is resumed, if the transmission includes an incomplete CBG, the transmission is resumed after the incomplete CBG is completed.

It should be further noted that the present embodiment is also applicable to a scenario in which the content of stopping transmission and the content of resuming transmission are the same, and the processing manner may be the same, which is not described herein again.

The following describes the scheme provided by this embodiment using various scenarios:

scene 1,

Stop/pause transmission is indicated in N symbols:

specifically, based on the indication information, a start symbol for stopping or suspending signal transmission is determined.

The start information refers to a start symbol for stopping/suspending transmission. At this time, when the indication information is used to indicate the content of the stop transmission, the time domain position of the stop transmission may include a start position: and stopping transmitting the last symbol where the first CBG contained in the content is positioned, or stopping transmitting the first symbol where the first CBG contained in the content is positioned.

Accordingly, the time domain location of the stop transmission comprises: the time domain position corresponding to the whole content after the starting position.

For example, the terminal receives a start symbol K to stop/pause transmission. The terminal stops/suspends transmission of the K, K +1, … end symbol.

In this scenario, the end, that is, the position of the terminated transmission signal, may be an end symbol of one time slot, or an end symbol of one scheduling.

When the indication information is also used to indicate that the transmission is resumed, the terminal sends all CBGs complete/incomplete contained in the { K, K +1, … end } symbol at the corresponding position;

accordingly, when it is determined that the transmission of the stopped or suspended CBG is an incomplete CBG, the incomplete CBG is supplemented as a complete CBG and the complete CBG is transmitted when it is determined to resume transmission.

For example, referring to fig. 5, assuming that the starting symbol of the currently stopped or suspended transmission is the third (3 rd), it is determined that the transmission is an incomplete CBG1, and complete CBGs 2, 3, 4, 5, 6; therefore, when the complete CBG is transmitted at the time of the final UL grant for resume transmission, the CBG1 needs to be supplemented with the complete CBG1 for further transmission.

Scene 2,

Range indicating stop/pause transmission: based on the indication information, a range to stop or suspend signal transmission is determined.

Specifically, based on the indication information, a symbol range for stopping or suspending signal transmission is determined. That is, the indication information needs to indicate the positions of the start symbol and the end symbol of the stop or pause signal transmission on the terminal side.

In this scenario, the time domain position at which transmission is stopped includes: and the time domain position corresponding to the part of the content after the starting position. For example, the indication information indicates only to stop/pause transmission, and may also indicate to stop/pause transmission and resume transmission.

The above symbol range may refer to a symbol range in which transmission is stopped/suspended. For example, the terminal receives the stop/pause transmission in the symbol range of K, K +1, … K + L. The terminal stops/suspends transmission of the K, K +1, … K + L symbols. That is, the start symbol in the symbol range is K, and the end symbol is K + L; wherein K and L are integers.

When the indication information is also used to indicate that the transmission is resumed, the terminal transmits all CBGs complete/incomplete contained in the { K, K +1, … K + L } symbol at the corresponding position.

For example, referring to fig. 6, assuming that the start and end symbols of the currently stopped or paused transmission are as shown in the figure (00110000), i.e., the 3rd and 4 th symbols are the symbols for stopping transmission, the transmission is determined to be incomplete CBGs 1 and 3 and complete CBG 2; therefore, when the complete CBG is transmitted at the time of the recovery transmission of the final UL grant, the CBGs 1, 3 need to be supplemented with the complete CBG for further transmission.

Scene 3,

Stop/pause transmission in CBG indication units: based on the indication information, a starting CBG to stop or suspend signal transmission is determined.

In this scenario, the indication information indicates only to stop/pause transmission, and may also indicate to stop/pause transmission and resume transmission.

The start information refers to a start CBG to stop/pause transmission. For example, the terminal receives a start CBG K to stop/suspend transmission.

In this scenario, one processing method is as follows:

when the indication information is used for indicating the content of stopping transmission, the time domain position of stopping transmission comprises the following initial positions: the content of the stop transmission contains the last symbol where the first CBG is located.

The time domain locations where transmission is stopped include: the time domain position corresponding to the whole content after the starting position. Namely, the terminal stops/pauses the last symbol and the subsequent symbols where the kth CBG is located. As in fig. 7, it is assumed that K =1 is shown.

When the indication information is also used to indicate that the transmission is resumed, the terminal transmits { K, K +1, … end } CBGs at the corresponding positions. The End may be an ending CBG of a slot or an ending CBG of a schedule.

The determining and transmitting the complete CBG to be sent when the transmission is resumed based on the CBG which stops or suspends the transmission comprises the following steps:

supplementing the incomplete CBG as a complete CBG when it is determined that transmission is stopped or suspended as an incomplete CBG, transmitting the complete CBG when it is determined that transmission is resumed.

For example, referring to fig. 7, assuming that K =1, the last symbol of K =1 (i.e., CBG1 in the figure) and all the subsequent symbols in the present scenario are selected to stop or pause transmission, and the symbol that stops or pauses transmission includes an incomplete CBG 1; therefore, when the complete CBG is transmitted at the time of the final UL grant for resume transmission, the CBG1 needs to be supplemented with the complete CBG for further transmission.

In this scenario, another processing manner is:

when the indication information is used for indicating the content of stopping transmission, the time domain position of stopping transmission comprises the following initial positions: the first symbol where the first CBG is included in the content to be stopped from being transmitted. The time domain locations where transmission is stopped include: the time domain position corresponding to the whole content after the starting position.

The start information refers to a start CBG to stop/pause transmission. For example, the terminal receives a start CBG K to stop/suspend transmission. The terminal stops/pauses the first symbol and subsequent symbols where the kth CBG is located. K =2 as shown in fig. 8.

When the indication information is also used to indicate that the transmission is resumed, the terminal transmits { K-1, K +1, … end } CBGs at the corresponding positions. The End may be an ending CBG of one slot or an ending CBG of one schedule.

When it is determined that the CBG whose transmission was stopped or suspended is incomplete, complementing the incomplete CBG as a complete CBG transmits the complete CBG when it is determined to resume transmission.

For example, in conjunction with fig. 8, assuming that K =2, the first symbol of K =2 (i.e. CBG2 shown in the figure) and all the symbols following it are selected to stop or pause transmission, because CBG2 belongs to the same symbol as part of CBG1, and thus the symbol that stops or pauses transmission includes incomplete CBG 1; therefore, when the complete CBG is transmitted at the time of the final UL grant for resume transmission, the CBG1 needs to be supplemented with the complete CBG for further transmission.

Scene 4,

Determining a range of stopping or suspending signal transmission based on the indication information:

one processing method of the scene is as follows:

the method further comprises the following steps:

when the indication information is used for indicating the content of stopping transmission, the time domain position of stopping transmission comprises the following initial positions: the last symbol where the first CBG is contained in the content to be stopped from transmission.

The time domain locations where transmission is stopped include: and the time domain position corresponding to the part of the content after the starting position.

Namely, the CBG contained in the last symbol of the starting CBG and the subsequent L-1 symbol is taken as the CBG range of the stop or pause signal transmission; wherein L is an integer greater than 1. The indication information in this scenario only indicates stopping/pausing of transmission, and may also indicate stopping/pausing of transmission and resuming of transmission.

It is further noted that the method further comprises: if the time domain position of the transmission stop is the time domain position corresponding to the partial content after the starting position, the time domain position of the transmission stop comprises:

stop transmitting the first symbol of the last CBG contained in the content, or

Stop transmitting the last symbol in which the last CBG contained in the content is located, or

And recovering the first symbol of the last CBG contained in the transmission content.

That is, the termination position of the transmission stop may be the first symbol or the last symbol where the last CBG in the last content of the transmission stop is located; but of course also the first symbol where the last CBG contained in its content was when transmission was resumed.

The start information refers to a start CBG to stop/pause transmission. For example, the terminal receives a start CBG K to stop/suspend transmission. The terminal stops/pauses the last symbol where the kth CBG is located and the subsequent L-1 symbol, the CBG stopping/pausing transmission is 0111000 as shown in fig. 9, i.e. transmission is stopped starting from CBG1 until the two subsequent symbols terminate. As shown in fig. 9, K =1, L =2, L-1=1, i.e., a CBG that starts and ends a stop or pause transmission from the last symbol of CBG1 and its subsequent 1 symbol.

When the indication information is also used to indicate that the transmission is resumed, the terminal transmits { K, K +1, … K + L-1} CBGs at the corresponding positions. The End may be an ending CBG of a slot or an ending CBG of a schedule.

For example, with reference to FIG. 9, CBG1 and CBG3 are incomplete CBGs; therefore, when the complete CBG is transmitted at the time of the recovery transmission of the final UL grant, the CBGs 1, 3 need to be supplemented with the complete CBG for further transmission.

Another processing method of the scene is as follows:

when the indication information is used for indicating the content of stopping transmission, the time domain position of stopping transmission comprises the following initial positions:

the content of the stop transmission contains the first symbol where the first CBG is located.

The start information refers to a start CBG to stop/pause transmission. For example, when the indication information is also used to indicate that the transmission is resumed, the terminal transmits { K-1, K, K +1, … K + L-2} CBGs at the corresponding positions.

The method further comprises the following steps: if the time domain position for stopping transmission is the time domain position corresponding to the partial content after the starting position, the time domain position for stopping transmission comprises:

stop transmitting the first symbol of the last CBG contained in the content, or

That is, the termination position of the transmission stop may be the first symbol or the last symbol where the last CBG in the last content of the transmission stop is located; but of course also the first symbol where the last CBG contained in its content was when transmission was resumed. For example, the terminal stops/pauses the first symbol and the subsequent L-1 symbol where the kth CBG is located.

As shown in fig. 10, K =2, the first symbol in which CBG2 is located includes a part of CBG 1; in addition, when L =2, L-1=1, that is, all CBGs included in one symbol after the first symbol in which CBG2 is located, is a range in which signal transmission is stopped or suspended; within this range incomplete CBGs 1, 3 are included; therefore, at the time of transmission, the CBGs 1, 3 are supplemented as complete CBGs before resuming transmission.

On the basis of the foregoing solution, in the solution provided in this embodiment, the method further includes:

receiving the indication Information through Downlink Control Information (DCI);

or, receiving the indication information through Radio Resource Control (RRC) information;

or, determining the indication information through a timing relationship;

or, determining the indication information through terminal equipment parameters;

alternatively, the indication information is determined by a common signal.

That is, the indication information may be indicated through DCI/RRC; or, the timing relationship is implicitly obtained, for example, the timing relationship may be timing for a start position of stopping/suspending transmission, that is, when there is a start point of a certain timing, a corresponding symbol position after a certain period of time has elapsed may be determined as the start position of stopping/suspending transmission, and in addition, when determining content of stopping/suspending transmission, all content after the start position may be taken as a corresponding time domain position by default, and a symbol range corresponding to a part of content may also be set, for example, (L-1) symbols, that is, content corresponding to L-1 symbols after the start position is taken as a time domain position of stopping/suspending transmission;

alternatively, the indication information may be indicated by UE specific or Common signaling.

It can be seen that, by adopting the scheme provided by the above embodiment, when the indication information is received, the content of stopping transmission is determined, and transmission is stopped and/or resumed based on the indication information; therefore, the resources for stopping or suspending transmission are integer symbols, and the integer CBGs are transmitted when the transmission is resumed, so that the problem of transmitting incomplete CBGs and the problem of different frequency domain resources on different symbols is avoided, and the flexible scheduling is facilitated.

Fig. 11 is a terminal device provided in an embodiment of the present application, including:

a first communication unit 1101 for receiving instruction information for instructing to stop transmission and to resume the content of transmission; wherein the content of the stop transmission and the content of the resume transmission are partially different;

a first processing unit 1102 configured to stop transmission based on the indication information and/or resume transmission based on the indication information.

A first processing unit 1102, configured to, when the indication information is used to indicate a time domain position where transmission is stopped, resume the content of transmission to include all CBGs from which transmission is stopped. And the transmission stopping all CBGs including incomplete CBGs.

That is, when the transmission is resumed, if the transmission includes an incomplete CBG, the transmission is resumed after the incomplete CBG is completed. It should be noted that, resuming transmission may be understood as: initiating retransmission for the case where a data packet is scheduled but not transmitted or not completely transmitted; the scheduling manner for resuming transmission may include new transmission scheduling signaling, retransmission scheduling signaling, and the like, and the scheduling form is not limited, and is not exhaustive in this embodiment.

scene 1,

Stop/pause transmission is indicated in N symbols:

Correspondingly, the time domain position for stopping transmission comprises: the time domain position corresponding to the whole content after the starting position.

Scene 2,

In this scenario, the time domain position at which transmission is stopped includes: and the time domain position corresponding to the part of the content after the starting position. For example, the indication information indicates only stop/pause of transmission, and may also indicate stop/pause of transmission and resumption of transmission.

Accordingly, when it is determined that the CBG whose transmission is stopped or suspended is incomplete, the incomplete CBG is supplemented as a complete CBG, and the complete CBG is transmitted when it is determined to resume transmission.

Scene 3,

In this scenario, one processing manner is:

a first processing unit 1102, configured to, when the indication information is used to indicate that the content is to be stopped from being transmitted, start positions included in the time domain position where the transmission is stopped are: the last symbol where the first CBG is contained in the content to be stopped from transmission.

For example, with reference to fig. 7, assuming that K =1, the last symbol of K =1 (i.e., CBG1 in the figure) and all subsequent symbols in the present scenario are selected to stop or suspend transmission, and the symbols stopping or suspending transmission include an incomplete CBG 1; therefore, when the complete CBG is transmitted at the time of the final UL grant for resume transmission, the CBG1 needs to be supplemented with the complete CBG for further transmission.

In this scenario, another processing manner is:

a first processing unit 1102, configured to, when the indication information is used to indicate that the content is to be stopped from being transmitted, stop the transmission at a time domain position that includes a starting position: the first symbol where the first CBG is included in the content to be stopped from being transmitted. The time domain locations at which transmission is stopped include: the time domain position corresponding to the whole content after the starting position.

When the indication information is also used to indicate that the transmission is resumed, the terminal transmits { K-1, K +1, … end } CBGs at the corresponding positions. The End may be an ending CBG of a slot or an ending CBG of a schedule.

For example, in conjunction with fig. 8, assuming that K =2, the first symbol of K =2 (i.e. CBG2 shown in the figure) and all the symbols following it are selected to stop or pause transmission, because CBG2 belongs to the same symbol as part of CBG1, and thus the symbol that stops or pauses transmission includes incomplete CBG 1; therefore, when the complete CBG is transmitted at the time of the recovery transmission of the final UL grant, the CBG1 needs to be supplemented with the complete CBG for transmission.

Scene 4,

Determining, based on the indication information, a range to stop or pause signal transmission:

one processing method of the scene is as follows:

The time domain locations at which transmission is stopped include: the time domain position corresponding to the partial content after the starting position.

It should be further noted that, if the time domain position where transmission is stopped is the time domain position corresponding to the partial content after the start position, the first processing unit 1102 is configured to stop transmitting the time domain position including:

stop transmitting the first symbol of the last CBG contained in the content, or
