Description

Transmission method and device for uplink channel

Technical Field

The present application relates to the field of wireless communications technologies, and in particular, to a method and an apparatus for transmitting an uplink channel.

Background

In a 5G NR (New Radio, New air interface), when at least one PUCCH (Physical Uplink Control Channel) carrying UCI (Uplink Control Information) overlaps with a PUSCH (Physical Uplink Shared Channel), or overlaps with a PUCCH carrying SR (Scheduling Request), UCI may be multiplexed on the PUSCH or the PUCCH carrying SR for transmission.

In the Rel-16 phase, for the case of collision between uplink channels on the same carrier with the same physical layer priority, it may be supported that an uplink Channel with higher LCH (Logical Channel) priority is transmitted preferentially in a UE (User Experience), that is, an uplink Channel may be interrupted by an uplink Channel with higher LCH priority later than the starting position.

Therefore, when there is UCI multiplexed on an uplink channel resource for transmission, if the uplink channel resource is interrupted by another uplink channel with a later starting position, the UCI multiplexed on the uplink channel resource is also discarded, resulting in a decrease in downlink transmission efficiency.

Detailed Description

Hereinafter, some terms in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.

(1) In the embodiments of the present application, the terms "network" and "system" are often used interchangeably, but those skilled in the art can understand the meaning.

(2) In the embodiments of the present application, the term "plurality" means two or more, and other terms are similar thereto.

(3) "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

In 5G R15 NR, from the viewpoint of PAPR (Peak-to-Average Power Ratio) reduction and CM (cubic metric), simultaneous transmission of a PUCCH and a PUSCH having overlapping time domain resources is not supported, and simultaneous transmission of a plurality of overlapping PUCCHs on the same carrier is also not supported.

When all or part of symbols of a PUCCH and a PUSCH overlap in a time domain, it is necessary to determine whether a first symbol corresponding to an uplink channel with an earliest start in the PUCCH and the PUSCH meets a predefined time condition (time), and if so, transferring UCI carried on the PUCCH to the PUSCH for transmission, so that the PUCCH is not transmitted any more, and simultaneous transmission of the PUCCH and the PUSCH is avoided. Fig. 1 is a schematic diagram illustrating multiplexing of a first uplink channel in the related art;

when a plurality of PUCCHs carrying UCI overlap in time domain, it is also necessary to determine whether the first symbol of the initial earliest uplink channel in the overlapped PUCCHs meets a predefined time condition, and when the first symbol meets the predefined time condition, UCI on the plurality of PUCCHs can be transmitted in a combined manner, and UCI on the plurality of PUCCHs can be transmitted on one PUCCH channel at the same time, thereby avoiding simultaneous transmission of the plurality of PUCCHs.

In R15, it is defined that the condition that the time is not satisfied does not occur, that is, the condition that the time is not satisfied is wrong scheduling, and there is no execution behavior, and when scheduling and configuring, a corresponding base station needs to ensure that the time is always satisfied between overlapping channels. the time is determined according to transmission parameters, processing capacity, subcarrier spacing and the like of a plurality of channels overlapped by time domains, and has different time definitions for different situations.

When the time domain overlapping of a plurality of PUCCHs and the time domain overlapping of the PUCCHs and the PUSCH exist at the same time, the overlapped PUCCHs are processed according to the multiplexing transmission rule among the PUCCHs to obtain one PUCCH, and then the time domain overlapping of the PUCCH and the PUSCH is processed. Fig. 2 is a schematic diagram illustrating multiplexing of a second uplink channel in the related art.

Specifically, the HARQ-ACK carried on the PUCCH may be transferred to the PUSCH for transmission; and when the CSI carried on the PUCCH does not contain the CSI in the PUSCH carrying the UCI, the CSI can be transferred to the PUSCH for transmission, otherwise, the CSI is discarded. Particularly, the SR is carried on the PUCCH, and if the PUSCH overlapped with the PUCCH contains the UL-SCH, the SR is discarded and the PUSCH is transmitted; if the PUSCH does not include the UL-SCH, the PUSCH overlapping the PUCCH is discarded, and the SR is transmitted on the PUCCH.

When the PUCCH overlaps with the PUSCH on multiple carriers, the PUSCH containing aperiodic channel state information (a-CSI) may be preferentially selected as the PUSCH carrying UCI on PUCCH, when there is no PUSCH carrying a-CSI, the PUSCH with PDCCH or DCI scheduling may be preferentially selected, and if the PUSCH types on multiple CCs (Component carriers) are identical, the PUSCH on the Carrier with the smallest Carrier number may be selected for carrying UCI.

The above describes in detail how to perform multiplexing transmission when there is an overlap between all or part of symbols of at least one PUCCH and one PUSCH in the time domain, or there is an overlap between part or part of symbols of a plurality of PUCCHs in the time domain.

In the related art, when there is UCI multiplexed on an uplink channel resource for transmission, if the uplink channel resource is interrupted by another uplink channel with a later starting position, the UCI multiplexed on the uplink channel resource for transmission is also discarded, resulting in a decrease in downlink transmission efficiency. Fig. 3 is a schematic diagram illustrating uplink channel transmission in the related art; the PUCCH resource of HARQ-ACK overlaps with a CG1(Configured Grant1, configuration Grant 1) PUSCH, HARQ-ACK multiplexing is transmitted on CG1 PUSCH, however, the physical layer of the terminal receives a CG2 PUSCH PDU, so the terminal needs to prioritize the CG2 PUSCH and discard the CG1 PUSCH transmission, resulting in that the HARQ-ACK transmission multiplexed on the CG1 PUSCH is also discarded, resulting in that the base station needs to retransmit the downlink transmission corresponding to HARQ-ACK, which affects downlink transmission efficiency.

The present application provides a transmission method and device for an uplink channel, so as to ensure that a network side device can timely and correctly acquire feedback information of downlink transmission that has occurred, and perform retransmission according to actual conditions, thereby improving downlink transmission efficiency.

The terminal is a device with a wireless communication function, can be deployed on land, and comprises an indoor or outdoor, a handheld or a vehicle-mounted terminal; can also be deployed on the water surface (such as a ship and the like); and may also be deployed in the air (e.g., airplanes, balloons, satellites, etc.).

The base station in the present application may also be a device that provides a terminal with a wireless communication function in other communication systems that may appear in the future.

In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be described in further detail with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all 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 application.

As shown in fig. 4, a structure diagram of a transmission system of an uplink channel provided in an embodiment of the present application is shown, where the transmission system includes a terminal 40 and a network side device 41, where:

a terminal 40, configured to determine whether there is multiplexed uplink control information on the first uplink channel resource; determining that multiplexed uplink control information exists on a first uplink channel resource, and when a second uplink channel resource which overlaps with the first uplink channel resource in a time domain exists, a terminal transmits a first uplink channel, wherein the first uplink channel cannot be interrupted by the second uplink channel;

a network side device 41, configured to determine that there is multiplexed uplink control information on a first uplink channel resource sent by a terminal, and there is a second uplink channel resource overlapping with the first uplink channel resource in time domain; and receiving the first uplink channel sent by the terminal on the first uplink channel resource, and not receiving the first uplink channel on the second uplink channel resource.

In the application, when a terminal determines that there is multiplexed uplink control information on a first uplink channel resource and there is a second uplink channel resource overlapping with the first uplink channel resource in a time domain, the first uplink channel transmitted by the terminal is not interrupted by the second uplink channel, and a corresponding network side device receives the first uplink channel sent by the terminal on the first uplink channel resource and does not receive on the second uplink channel resource; the network side device can timely and correctly receive the feedback information of the terminal aiming at the downlink transmission, and further accurately judge whether retransmission needs to be executed according to the obtained feedback information, so that the downlink transmission efficiency is improved.

In a possible implementation manner, when the terminal determines that there is the multiplexed uplink control information on the first uplink channel resource and there is the second uplink channel resource overlapping with the first uplink channel resource in the time domain, the terminal performs uplink channel transmission, which specifically includes:

after the MAC layer of the terminal transmits the PDU or SR corresponding to the first uplink channel resource to the PHY layer, the PDU or SR corresponding to the second uplink channel resource is not transmitted to the PHY layer any more, and the PHY layer of the terminal transmits the first uplink channel on the first uplink channel resource at the moment; or

The method comprises the steps that the MAC layer of a terminal transmits PDU (protocol data Unit) or SR (scheduling request) corresponding to first uplink channel resources and second uplink channel resources to a physical PHY (physical layer), and when the PHY layer of the terminal determines that the received first uplink channel resources have multiplexed uplink control information, the PHY layer of the terminal transmits the first uplink channel on the first uplink channel resources and discards the second uplink channel;

in this application, when the first uplink channel resource and the second uplink channel resource overlap in the time domain, the starting position of the first uplink channel resource is earlier than the starting position of the second uplink channel resource, and the priorities of the physical layers of the first uplink channel and the second uplink channel are the same.

It should be noted that, the PHY layer of the terminal transmits the PDU or SR corresponding to the first uplink channel resource as the first uplink channel, and discards the second uplink channel is to discard the PDU or SR corresponding to the second uplink channel resource.

The MAC layer of the terminal does not transmit the second uplink channel to the PHY layer of the terminal, or the terminal transmits the first uplink channel and the second uplink channel to the PHY layer of the terminal, but the PHY layer of the terminal discards the second uplink channel, and the terminal can not transmit the second uplink channel under the two conditions, so that the second uplink channel can not influence the transmission of the first uplink channel, namely the second uplink channel can not interrupt the transmission of the first uplink channel, and the first uplink channel can be timely and correctly transmitted to the network side equipment.

Correspondingly, the network side equipment receives an uplink channel transmitted by the terminal, when the network side equipment receives the uplink channel transmitted by the terminal, the network side equipment determines that the original PUCCH resource of the multiplexed uplink control information exists, and receives the uplink control information on the original PUCCH resource of the multiplexed uplink control information, when the network side equipment determines that the uplink control information is not received on the original PUCCH resource of the multiplexed uplink control information, the network side equipment determines that the multiplexed uplink information exists on the first uplink channel resource transmitted by the terminal, and when the network side equipment determines that the second uplink channel resource which is overlapped with the first uplink channel resource in time domain exists, the network side equipment receives the first uplink channel transmitted by the terminal on the first uplink channel resource and does not receive the second uplink channel resource any more; the network side equipment determines that the uplink control information is not received on the original PUCCH resource of the multiplexed uplink control information, and determines that the receiving result of the original PUCCH resource of the multiplexed uplink control information is failure or DTX; or

After the network side equipment determines that the first uplink channel corresponds to the dynamically scheduled PUSCH, the network side equipment receives the first uplink channel sent by the terminal on the first uplink channel resource and does not receive the first uplink channel on the second uplink channel resource.

The network side equipment determines that the starting position of the first uplink channel resource is earlier than the starting position of the second uplink channel resource.

In the present application, if the first uplink channel is a PUSCH, the uplink control information includes at least one of HARQ-ACK, CSI, and SR; or

In a possible implementation manner, when the terminal determines that there is no multiplexed uplink control information on the first uplink channel resource and there is a second uplink channel resource overlapping with the first uplink channel resource in the time domain, the terminal stops or cancels transmission of the first uplink channel and transmits the second uplink channel.

In the application, the priority of the logical channel of the second uplink channel is higher than the priority of the logical channel of the first uplink channel, and the terminal is configured with transmission based on the priority of the logical channel in advance, so when the first uplink channel resource does not have multiplexed uplink control information, the transmission of the second uplink channel affects the transmission of the first uplink channel, so that the transmission of the first uplink channel is stopped or cancelled, and the transmission of the first uplink channel is stopped as the interruption of the transmission of the first uplink channel.

When the first uplink channel resource and the second uplink channel resource are overlapped on the time domain, the initial position of the first uplink channel resource is earlier than the initial position of the second uplink channel resource, and the physical layer priorities of the first uplink channel and the second uplink channel are the same.

If the terminal determines that the multiplexed uplink control information does not exist on the first uplink channel resource, when the terminal transmits the second uplink channel:

when the terminal determines that target data exists on the second uplink channel resource and needs to be transmitted, the second uplink channel is transmitted, and the first uplink channel is stopped or cancelled; or

When the terminal determines the time for obtaining the target data from the second uplink channel resource, the second uplink channel is transmitted after the first uplink channel resource, and the first uplink channel is stopped or cancelled;

if the second uplink channel resource is a PUSCH, the target data is at least one of UL-SCH, TB and PDU; or

And if the second uplink channel resource is PUCCH, the target data is SR.

Correspondingly, the network side device may receive the uplink channel transmitted by the terminal, and when the network side device receives the uplink channel transmitted by the terminal, the network side device determines that there is no multiplexed uplink control information on the first uplink channel resource sent by the terminal, and then receives the uplink channel on the first uplink channel resource and the second uplink channel resource.

When the network side equipment receives the uplink channels on the first uplink channel resource and the second uplink channel resource, and the network side equipment determines that the result of receiving the first uplink channel is failure or DTX, the network side equipment receives the second uplink channel on the second uplink channel resource.

In the present application, if the first uplink channel is a PUSCH, the uplink control information includes at least one of a HARQ-ACK, a CSI, and an SR; or

In the present application, the determined transmission modes of the uplink channel are different according to whether there is multiplexed uplink control information on the first uplink channel resource, and specifically, the following embodiments are used to describe in detail the transmission method of the uplink channel in the present application, in terms of two cases that there are multiplexed uplink control information on the first uplink channel resource and there is no multiplexed uplink control information on the first uplink channel resource.

The first embodiment is as follows: the first uplink channel resource has multiplexed uplink control information.

Fig. 5 is a schematic diagram of transmission of an uplink channel according to an embodiment of the present application.

Assuming that a terminal is configured with two CG configurations on the same carrier, the priorities of physical layers of the two CG configurations are the same, and there is overlap in time domain resources, the terminal can only transmit one of the cgchs in the overlapping portion of the CG1 PUSCH and the CG2 PUSCH, and the PUCCH carrying the uplink control information and the CG1 PUSCH are overlapped, and the priorities of the physical layers of the PUCCH carrying the uplink control information and the CG1 PUSCH are the same, which may be the same as a high priority or a low priority, and is not particularly limited.

When the time condition that uplink control information on the PUCCH is transferred to the PUSCH for transmission is met between the PUCCH carrying the uplink control information and the CG1 PUSCH, the terminal transfers the uplink control information on the PUCCH to the CG1 PUSCH for transmission without transmitting the PUCCH, so that simultaneous transmission of a plurality of uplink channels is avoided. At this time, CG1 PUSCH is the first uplink channel in the embodiment of the present application.

When the terminal starts to prepare or transmit a CG1 PUSCH, data corresponding to a CG2 PUSCH arrives, the CG1 PUSCH and the CG2 PUSCH overlap in a time domain, the CG2 PUSCH is a second uplink channel in the embodiment of the present application, and the priority of a logical channel of a PDU corresponding to a CG2 PUSCH is higher, then:

when the MAC layer of the terminal determines that multiplexed uplink control information exists on a CG1 PUSCH, after a PDU (protocol data Unit) corresponding to a CG1 PUSCH or a PHY (scheduling request) layer of an SR transmission terminal is transmitted, the PDU corresponding to a CG2 PUSCH or the PHY layer of the SR transmission terminal is not transmitted, so that the PHY layer of the terminal does not know that the CG2 PUSCH needs to transmit data, and the PHY layer of the terminal transmits the CG1 PUSCH and the multiplexed uplink control information; or

And the MAC layer of the terminal transmits the PDU or SR corresponding to the CG1 PUSCH and the PDU or SR corresponding to the CG2 PUSCH to the PHY layer of the terminal, the PHY layer of the terminal determines whether multiplexed uplink control information exists on the CG1 PUSCH, and when the PHY layer determines that the multiplexed uplink control information exists on the CG1 PUSCH, the PHY layer of the terminal transmits the CG1 PUSCH and the multiplexed uplink control information and discards the CG2 PUSCH.

Correspondingly, the network side equipment receives CG PUSCHs transmitted by the terminal, wherein the CG PUSCHs comprise CG1 PUSCHs and/or CG2 PUSCHs.

In this embodiment, the network side device knows the original PUCCH where the multiplexed uplink control information exists, however, the network side device does not know on which PUSCH the terminal may transmit data, that is, the network side device does not know whether the terminal transmits data on CG1 PUSCH or CG2 PUSCH; therefore, the network side device needs to detect the resources corresponding to the original PUCCH, CG1 PUSCH, and CG2 PUSCH of the multiplexed uplink control information, and determine whether there is a corresponding transmission according to the actual reception situation.

Specifically, when the receiving result of the original PUCCH receiving the multiplexed uplink control information by the network side device is failure or DTX, the network side device determines that the uplink control information is transferred to CG1 PUSCH for transmission, and the network side device receives CG1 PUSCH and the uplink control information on resources corresponding to CG1 PUSCH and does not receive on CG2 PUSCH.

In one possible implementation, when the network side device receives the PUCCH, the network side device may further attempt to receive a CG2 PUSCH on a resource corresponding to a CG2 PUSCH.

Example two: there is no multiplexed uplink control information on the first uplink channel resource.

Fig. 6 is a schematic diagram of another uplink channel transmission provided in the embodiment of the present application.

Assuming that a terminal is configured with two CG configurations on the same carrier, the priorities of the two CG configurations in physical layers are the same, and there is an overlap in time domain resources, the terminal can only transmit one of CG1 PUSCH and CG2 PUSCH overlapping portions, and a PUCCH carrying uplink control information is not overlapped with CG1 PUSCH and CG2 PUSCH in time domain.

The terminal determines that a PUCCH carrying uplink control information and a CG1 PUSCH are not overlapped in time domain, and a PHY layer of the terminal sends the PDU transmitted on the CG1 PUSCH and the CG2 PUSCH according to the sequence of the PDU transmitted on the MAC layer of the terminal, so that the PUSCH corresponding to the PDU received last is more preferential.

Assuming that the arrival time of the CG1 PUSCH is earlier than the arrival time of the CG2 PUSCH, the terminal PHY will stop or cancel the CG1 PUSCH transmission and preferentially transmit the CG2 PUSCH.

The network side equipment does not know which PUSCH the terminal transmits data on, so the network side equipment needs to detect two PUSCHs on resources corresponding to a CG1 PUSCH and a CG2 PUSCH respectively, judge whether corresponding transmission exists according to an actual receiving condition, and when the network side equipment receives the CG1 PUSCH and the receiving result is failure or DTX, the network side equipment considers that the CG1 PUSCH is not transmitted or is stopped halfway, and further receive the CG2 PUSCH on the resource corresponding to the CG2 PUSCH.

It should be noted that, in this embodiment, only overlapping of two CG PUSCHs on the same carrier is taken as an example for description, two CG PUSCHs on the same carrier may also be replaced by two PUCCHs carrying SRs on the same carrier, or by one CG PUSCH and one DG PUSCH on the same carrier, or by one PUSCH and one PUCCH carrying SR on the same or different carriers.

It should be noted that, in the embodiment where the multiplexed uplink control information exists on the first uplink channel resource, only the PUCCH carrying the uplink control information overlaps with the CG1 PUSCH, and does not overlap with the CG2 PUSCH is taken as an example for illustration; when the PUCCH carrying the uplink control information overlaps with CG1 PUSCH and CG2 PUSCH, multiplexing the PUCCH carrying the uplink control information on CG1 PUSCH, and the subsequent transmission mode is the same as that of the first embodiment; when one or more CG PUSCHs are replaced by DG PUSCHs and a PUCCH is overlapped with a plurality of PUSCHs, the technical scheme provided by the application is also applicable;

in the embodiment where the multiplexed uplink control information exists on the first uplink channel resource, the method includes: the uplink control information can be HARQ-ACK, CSI or HARQ-ACK + CSI.

It should be noted that, when PUCCH and PUSCH multiplexing transmission with different priorities are supported, the PUCCH and PUSCH may also be of different priorities; when determining which PUSCH to transmit between PUSCHs supporting overlapping of time domain resources on the same carrier according to the PDU arrival time only (that is, regardless of the priority of the first PUSCH and the second PUSCH, determining which PUSCH to transmit according to which is the last PUSCH of the received PDU), the first PUSCH and the second PUSCH may also be of different priorities.
