Technical Field

The present application belongs to the field of communications technologies, and in particular, to an uplink transmission method, apparatus, and device.

Background

When an uplink shared channel (e.g., a Physical Uplink Shared Channel (PUSCH)) of a terminal device enables an uplink transmission skip (UL skip) function and there is no data to be transmitted in a data memory of the terminal device, even if a base station schedules a user for data transmission, the UL skip function allows the user to ignore the scheduling of the base station and not perform uplink transmission.

In the related art, in a case where the UL blanking function is enabled in the uplink shared channel of the terminal device, if there is a resource conflict between a time domain resource of an uplink control channel (e.g., a Physical Uplink Control Channel (PUCCH)) and a time domain resource of a dynamically scheduled uplink shared channel, since the PUSCH may have no data to transmit, the MAC layer cannot generate a PDU based on whether there is data, depending on whether there is UCI to multiplex the PDU.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. 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.

Technical terms related to technical solutions provided by embodiments of the present application will be explained below:

1. time domain overlapping of transmission resources (or called time domain collision)

Compared with the existing mobile communication system, the future 5G mobile communication system needs to adapt to more diversified scenes and service requirements. The main scenarios of 5G include enhanced mobile broadband (eMBB), massive machine type communications (mtc), and ultra-reliable and low latency communications (URLLC), which have requirements for high reliability, low latency, large bandwidth, wide coverage, and the like on a mobile communication system. The UE may support different services, for example, the UE may support both a URLLC service with low latency and high reliability and an eMBB service with large capacity and high rate. New Radio (NR) systems may have overlapping transmission resource time domains due to different channels having different starting symbols and lengths. In general, in order to maintain uplink single carrier characteristics, when a plurality of overlapping uplink transmission resources are transmitted in one slot, the single carrier characteristics of the UE are destroyed, and a difference in transmission power causes deterioration of channel estimation performance. For this case, usually considered as a conflict, a corresponding conflict solution needs to be designed, and some information needs to be merged or discarded.

2. Uplink channel

The uplink control channel includes: a Physical Uplink Control Channel (PUCCH).

The uplink shared channel includes: a Physical Uplink Shared Channel (PUSCH).

3. Physical layer defined UCI multiplexing on PUSCH

Uplink control information (e.g., UCI) is transmitted on an uplink control channel (e.g., PUCCH). If the terminal device is transmitting data on an uplink shared channel (e.g., PUSCH), in principle, PUCCH and PUSCH may be transmitted simultaneously, i.e., UCI is retained in PUCCH. However, this increases the Cubic Metric (Cubic Metric); furthermore, if the requirements for out-of-band transmission are to be met at higher transmit power and the PUSCH and PUCCH are transmitted simultaneously with a large separation in the frequency domain (PUCCH is typically transmitted at both ends of the band), this can present challenges for Radio Frequency (RF) implementations. Therefore, in general, if there is time coincidence between the PUCCH resource requiring UCI transmission and the PUSCH resource, and the base station guarantees that the condition of UCI multiplexing processing time is satisfied when scheduling the PUSCH, UCI and data are multiplexed on the PUSCH, avoiding simultaneous transmission of PUCCH.

4. PUCCH and PUSCH collision handling

In NR R15, simultaneous transmission of PUCCH and PUSCH is not supported within one PUCCH group (PUCCH group) regardless of whether the PUCCH and PUSCH are in the same serving cell or different serving cells. When the PUCCH and PUSCH time domain resources overlap (including partial time domain resource overlap and full time domain resource overlap), the UE may discard or merge according to the corresponding rule under the condition that a certain time requirement is met.

For example, if a PUCCH carrying a Scheduling Request (SR) overlaps with a PUSCH not carrying an uplink shared channel (UL-SCH), the UE discards the PUSCH and transmits the SR PUCCH. Or the UE multiplexes Uplink Control Information (UCI) (except for SR) carried on the PUCCH into the PUSCH and transmits the uplink control information. For example, if PUCCH1 carrying hybrid automatic repeat request acknowledgement (HARQ-ACK) or PUSCH 2 carrying Channel State Information (CSI) overlaps with PUCCH1 carrying PUSCH 2, the UE multiplexes HARQ-ACK/CSI carried on PUCCH1 into PUSCH 2 for transmission.

Specifically, the UE firstly processes time domain resource overlapping (if any) between multiple PUCCHs, and the processing result is one or multiple PUCCHs with non-time domain resource overlapping, and then the UE processes time domain resource overlapping between the PUCCH and a PUSCH, if the PUCCH is only overlapped with one PUSCH, the UE multiplexes UCI (excluding SR) in the PUSCH, and if the PUCCH is only overlapped with multiple PUSCHs, the UE selects one PUSCH for multiplexing according to a multiplexing rule in the related art, where the first multiplexing rule (i.e., the sequence of PUSCHs for instructing the UE to select the multiplexed UCI) is as follows:

rule 1: PUSCH carrying Aperiodic channel state information (A-CSI).

Rule 2: PUSCH with the earliest starting slot.

Rule 3: dynamically scheduled PUSCH > configures a granted PUSCH or a semi-persistent (semi-persistent) PUSCH.

Rule 4: PUSCH with small serving cell index (index) > PUSCH with large serving cell index.

Rule 5: PUSCH early in transmission symbol > PUSCH late in transmission symbol.

Illustratively, the physical layer priority of the PUCCH is determined by the priority of the UCI carried thereby. For example, the priority of the SR is configured by Radio Resource Control (RRC), the periodic CSI and semi-persistent CSI (SP-CSI) priorities are predefined as low priority, and the priority of the HARQ-ACK is indicated by its corresponding DCI or determined according to the configuration of semi-Persistent Scheduling (SPs). The transmission priority of the PUSCH is indicated by scheduling Downlink Control Information (DCI) corresponding to the PUSCH, or the priority of the PUSCH for which the grant is configured by RRC.

When the time domain resources of the PUCCH and the PUCCH are overlapped or the time domain resources of the PUCCH and the PUSCH are overlapped, the UE processes the transmission with the same priority (the rule is same as R15) firstly and then processes the transmission with different priorities, and when the different priorities are processed, the UE cancels (or is called to discard) the transmission of the uplink resource with low priority and transmits the uplink resource with high priority under the condition of meeting a certain time requirement.

5. MAC layer defined uplink transmission skip function

The MAC layer defines the procedure for the terminal to carry out an uplink transmission skip (ulskiping) in the protocol TS 38.321. The MAC entity will not generate a MAC PDU for the HARQ entity if the following conditions are met:

condition 1: the MAC entity is configured with a parameter skippelinktxdynamic and the value of this parameter is set to true (true), and the MAC locates to the HARQ entity indicated in the uplink grant (UL grant).

Condition 2: there is no aperiodic CSI requested for this PUSCH transmission in the UL grant as specified in TS 38.212.

Condition 3: a MAC PDU includes zero MAC SDUs.

Condition 4: the MAC PDU contains only a periodic Buffer Status Report (BSR) and no data available for any Logical Channel Group (LCG), or the MAC PDU contains only a padding BSR.

In the related art, in a case where the uplink shared channel of the terminal device enables the UL blanking function, if there is a resource conflict between a time domain resource of an uplink control channel (e.g., PUCCH) and a time domain resource of a dynamically scheduled uplink shared channel, since the PUSCH may not have data to transmit, the MAC layer cannot generate a PDU based on whether there is data or not to be multiplexed according to whether there is UCI.

Specifically, in the case that the time domain resource of the uplink control channel (e.g., PUCCH) and the time domain resource of the dynamically scheduled uplink shared channel have resource conflict, the terminal device may choose not to generate PUSCH to transmit the uplink control information (e.g., UCI) on the PUCCH, or may choose to generate PUSCH to multiplex the uplink control information on the PUSCH for transmission.

Therefore, the resource multiplexed by the UCI cannot be determined at the network side, and the network side cannot accurately receive the UCI. Especially when the number of carriers is large, the network side device needs to perform blind detection on each carrier based on two assumptions of whether uplink control information is multiplexed on the PUSCH of the carrier, which increases the complexity of blind detection on the network side and causes a large burden on the network side.

In order to solve the above problem, embodiments of the present application provide an uplink transmission method, apparatus, and device, where if a terminal device enables an uplink transmission skip function, if a time domain resource of at least one uplink shared channel overlaps with a time domain resource of at least one uplink control channel, a MAC PDU may be generated in an MAC layer according to any one of the following processing manners: mode 1, if the MAC layer learns that the time domain resource of the uplink shared channel overlaps with the time domain resource of the uplink control channel, an MAC PDU is generated; mode 2, according to the multiplexing information notified to the MAC layer by the physical layer, generating MAC PDU; wherein, at least one uplink control channel carries at least one uplink control information. Therefore, under the condition that the uplink shared channel conflicts with the uplink control channel, the MAC PDU can be generated through the MAC layer, so that even if the terminal equipment has no data transmission, the terminal equipment can also support that the uplink control information carried on the uplink control channel can be multiplexed onto the uplink shared channel which enables the uplink transmission skipping function, and further, the network side equipment can accurately determine the multiplexing resources of the uplink control channel without two assumed blind detections, the complexity of the network side blind detection is reduced, and the system communication energy efficiency is improved.

The uplink transmission method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

In other words, the uplink transmission method may be executed by software or hardware installed in the terminal device. As shown in fig. 2, a data transmission method provided in an embodiment of the present application may include the following step 201.

The first processing mode is as follows: and under the condition that the terminal equipment enables an uplink transmission skipping function, if the time domain resource of at least one uplink shared channel is overlapped with the time domain resource of at least one uplink control channel, and if the MAC layer learns that the time domain resource of at least one uplink shared channel is overlapped with the time domain resource of at least one uplink control channel, generating the MAC PDU at the MAC layer.

The second processing mode is as follows: in the MAC Layer (or Layer 2, Layer 2), a MAC PDU is generated based on the multiplexing information notified to the MAC Layer by the physical Layer (or Layer 1, Layer 1).

In this embodiment, the at least one uplink control channel carries at least one uplink control information.

In this embodiment, the at least one uplink shared channel is located on one or more carriers.

It should be noted that the overlapping of the time domain resource of the at least one uplink shared channel and the time domain resource of the at least one uplink control channel refers to: there is a collision in time between the at least one uplink shared channel and the at least one uplink control channel. Illustratively, the time domain resource may be one or more slots/sub-slots/symbols/subframes.

In the embodiment of the present application, the terminal device enabling the uplink transmission skip function may be considered as the terminal device enabling the uplink transmission skip function of the uplink shared channel.

In the embodiment of the present application, the following relationship exists between the MAC PDU and uplink control information (e.g., UCI): 1) if the target uplink shared channel is overlapped with the uplink control channel resource, the MAC PDU and the UCI are multiplexed on the target uplink shared channel for transmission; or, 2) if the target uplink shared channel is not overlapped with the target uplink control channel resource, the UCI is transmitted on the target uplink control channel, and the MAC PDU is transmitted on the target uplink shared channel.

Optionally, in this embodiment of the present application, the multiplexing information may be used to indicate that the time domain resource of the at least one uplink shared channel overlaps with the time domain resource of the at least one uplink control channel.

Optionally, in this embodiment of the present application, the multiplexing information may also be used to indicate a target uplink shared channel. Among the at least one uplink shared channel, an uplink shared channel for carrying uplink control information of the at least one uplink control channel is provided. Further, at this time, the MAC layer may not need the physical layer to notify that there is a collision between the current uplink control channel and the shared channel, and the MAC layer only needs to directly generate the MAC PDU according to the multiplexing information notified by the physical layer.

Optionally, in an embodiment of the present application, the multiplexing information is used to indicate at least one of the following:

a target uplink control channel for carrying uplink control information of the at least one uplink control channel, among the at least one uplink control channel;

a target uplink shared channel for carrying uplink control information of the at least one uplink control channel, among the at least one uplink shared channel;

the at least one uplink shared channel;

the at least one uplink control channel.

It should be noted that, in this embodiment of the present application, one or more target uplink shared channels may be used, and one or more target uplink control channels may be used, which is not limited in this embodiment of the present application.

Optionally, in this embodiment of the present application, the multiplexing information may be notified to the MAC layer by the physical layer when the terminal device receives a scheduling grant (a downlink scheduling grant or an uplink scheduling grant).

Further optionally, in this embodiment of the application, when the scheduling grant is a downlink scheduling grant, the downlink scheduling grant is DCI for scheduling a part or all of the uplink control channels in the at least one uplink control channel. Illustratively, the downlink scheduling grant is a latest DCI for scheduling the one or more PUCCHs carrying the UCI.

Further optionally, in this embodiment of the application, when the scheduling grant is an uplink scheduling grant, the uplink scheduling grant is DCI for scheduling a part or all of the at least one uplink shared channel, or the uplink shared channel scheduled by the uplink scheduling grant and the at least one uplink control channel overlap in a time unit.

For example, in a case that the uplink scheduling grant schedules a DCI of a part of or all uplink shared channels in the at least one uplink shared channel, the uplink scheduling grant schedules a DCI of a PUSCH on a PCell.

For example, the time unit may be: subframe, slot, sub-slot, symbol, etc.

Further, when receiving the ending time slot or symbol of the DCI of the scheduling grant, the terminal device is notified to the MAC layer by the physical layer; or, the terminal device notifies the MAC layer by the physical layer X time units after receiving the ending slot or symbol of the DCI of the scheduling grant. Wherein X is predefined or network configuration or related to UE capability, and further, X may be a processing time of a downlink control channel (PDCCH).

Optionally, in this embodiment of the present application, the process of generating the MAC PDU by the terminal device in step 201 may further include the following step 201 a:

step 201 a: and generating the MAC PDU and transmitting the MAC PDU on the target uplink shared channel.

Wherein, the target uplink shared channel is: and the at least one uplink shared channel is used for carrying uplink control information of the at least one uplink control channel.

Illustratively, a MAC padding pdu (MAC padding pdu) is generated when the terminal device has no data. The terminal device has no data, and specifically, the terminal device may have no data in a Logical channel group (Logical channel group) corresponding to the PUSCH.

Illustratively, when the MAC layer generates a MAC PDU for the at least one PUSCH according to the multiplexing information, the MAC generates a MAC padding PDU when there is no UL-SCH on any one PUSCH.

Illustratively, when the MAC layer generates a MAC PDU according to the multiplexing information, the MAC layer generates a MAC padding PDU if there is no UL-SCH or no data on the target PUSCH.

Further optionally, in this embodiment, the uplink transmission method provided in this embodiment may further include the following step a 1:

step A1: and on the target carrier, forbidding to enable the uplink transmission skipping function.

Wherein, the target carrier is: and the carrier where the uplink shared channel is located is overlapped with the time domain resource of the uplink control channel.

Illustratively, the UE disables the enabled (disable) PUSCH UL blanking function when at least one PUCCH overlaps the PUSCH in time. Furthermore, on the carrier where the PUSCH with the conflict with the PUCCH is located, the PUSCH UL clipping function is forbidden to be enabled.

Optionally, in this embodiment of the application, for the processing mode 2, the uplink transmission method provided in this embodiment of the application may further include the following step B1, step B2, or step B3:

step B1: and under the condition that the at least one uplink control channel comprises a plurality of uplink control channels, determining the target uplink control channel from the plurality of uplink control channels according to a first multiplexing rule in a physical layer or an MAC layer.

Step B2: and under the condition that the at least one uplink shared channel comprises a plurality of uplink shared channels, determining the target uplink shared channel from the plurality of uplink shared channels according to a second multiplexing rule in a physical layer or an MAC layer.

Step B3: and when the at least one uplink shared channel comprises a plurality of uplink shared channels and the time domain resource of the target uplink control channel overlaps with the time domain resources of the plurality of uplink shared channels, determining the target uplink shared channel from the plurality of uplink shared channels according to a second multiplexing rule and the target uplink control channel in a physical layer or an MAC layer.

For example, the first multiplexing rule may be a PUCCH multiplexing rule of UCI on PUCCH.

In one example, the multiplexing rule of HARQ-ACK on PUCCH and the multiplexing rule of Scheduling Request (SR) on PUCCH are as shown in table 1 below:

TABLE 1

It should be noted that PF0 in the above table is PUCCH Format 0, PF1 in the above table is PUCCH Format 1, and PF2/3/4 in the above table is PUCCH Format 2/3/4.

For CSI + SR: transmitting SR and CSI on CSI PUCCH [1og ]₂(K+1)]bits is preset before the periodic/semi-static CSI information bit, and indicates the corresponding SR state (active or inactive) in the SR resource Id in an ascending manner.

For HARQ-ACK/SR/CSI: if HARQ-ACK is feedback on PDSCH without PDCCH scheduling, HARQ-ACK or HARQ-ACK + SR will be multiplexed on CSI PUCCH transmission.

If HARQ-ACK is feedback for PDSCH scheduled with PDCCH, HARQ-ACK or HARQ-ACK + SR + CSI will be multiplexed on one PUCCH for transmission. The PUCCH is determined in a plurality of resource sets configured by RRC based on HARQ-ACK, CSI and SR bit number.

For example, in step B2, in a case that the at least one uplink shared channel includes multiple uplink shared channels and the multiple uplink shared channels are located on a single carrier, the target uplink shared channel is determined based on at least one of the following:

an uplink shared channel with the earliest initial time domain position in the plurality of uplink shared channels;

triggering an uplink shared channel reported by aperiodic CSI from the plurality of uplink shared channels;

the physical layer informs the MAC layer to multiplex the uplink control information on the target uplink shared channel;

and the physical layer informs the MAC layer whether each uplink shared channel in the plurality of uplink shared channels multiplexes the uplink control information.

For example, taking the uplink shared channel as the PUSCH, when there are multiple PUSCHs and a single carrier, the PHY layer needs to determine the target PUSCH for carrying the UCI according to the second multiplexing rule. The specific multiplexing mode comprises the following steps: multiplexing mode 1: the target PUSCH is the PUSCH with the earliest starting time in a plurality of PUSCHs on the carrier wave; multiplexing mode 2: the target PUSCH is a PUSCH which triggers Aperiodic CSI reporting (A-CSI) in a plurality of PUSCHs on the carrier wave.

For example, in step B2, in a case that the at least one uplink shared channel includes multiple uplink shared channels and the multiple uplink shared channels are located on multiple carriers, the target uplink shared channel satisfies at least one of the following conditions:

an uplink shared channel with the earliest initial time domain position in a plurality of uplink shared channels on a first carrier;

triggering an uplink shared channel reported by aperiodic CSI from a plurality of uplink shared channels on a first carrier;

an uplink shared channel on a second carrier;

an uplink control channel on a third carrier.

Wherein the first carrier is a carrier whose number satisfies a predetermined condition (e.g., the number is the smallest) among the plurality of carriers; the second carrier is a carrier which is scheduled in an uplink manner among the plurality of carriers and has a serial number meeting the predetermined condition; the third carrier is a carrier which triggers aperiodic CSI reporting and has a number meeting the predetermined condition among the plurality of carriers.

For example, taking the uplink shared channel as the PUSCH, when there are multiple PUSCH, the PHY layer needs to determine the target PUSCH for carrying the UCI and the carrier where the target PUSCH is located according to the second multiplexing rule. Specifically, the multiplexing method includes: multiplexing mode 1: the target PUSCH is the PUSCH with the earliest starting time in a plurality of PUSCHs on the carrier wave with the smallest number; multiplexing mode 2: the target PUSCH is a PUSCH which triggers Aperiodic CSI reporting (A-CSI) in a plurality of PUSCHs on a carrier wave with the smallest number; multiplexing mode 3: the target PUSCH is a PUSCH of a carrier which is positioned in dynamic UL scheduling and has the smallest number in a plurality of carriers; and a multiplexing mode 4: the target PUSCH is a PUSCH of a carrier which triggers the aperiodic CSI reporting and has the smallest number, among the plurality of carriers.

Illustratively, the MAC layer or the physical layer determines the target uplink shared channel according to the second multiplexing rule. In an example, when the PHY layer notifies the MAC layer that the target PUCCH conflicts with the at least one PUSCH, the MAC layer may determine the target PUSCH for carrying the UCI according to the multiplexing rule of the target PUCCH and the UCI on PUSCH.

Optionally, in this embodiment, for the processing mode 1, if the MAC layer knows that the time domain resource of the at least one uplink shared channel overlaps with the time domain resource of the at least one uplink control channel, the uplink transmission method provided in this embodiment may further include the following step C1:

step C1: and determining a target uplink shared channel from the at least one uplink shared channel at the MAC layer according to a second multiplexing rule.

For example, taking the uplink shared channel as the PUSCH, when the MAC layer determines a target PUCCH carrying the one or more UCIs according to a second multiplexing rule (i.e., a PUCCH multiplexing rule of UCI on PUSCH), if the target PUCCH collides with at least one PUSCH, the MAC layer determines the target PUSCH carrying the UCI according to the target PUCCH and the second multiplexing rule.

For example, taking the uplink shared channel as the PUSCH, when at least one PUSCH on one or more carriers is located on multiple carriers, the MAC layer determines, according to the second multiplexing rule, a target PUSCH for carrying the UCI and a carrier on which the target PUSCH is located.

Illustratively, for example, when the uplink shared channel is PUSCH and the uplink control channel is PUCCH, the MAC layer determines a target PUCCH carrying the one or more UCI according to a first multiplexing rule (i.e., PUCCH multiplexing rule of UCI on PUCCH).

Illustratively, if the MAC layer knows that one or more PUCCHs carrying UCI are colliding with at least one PUSCH on one or more carriers, and when there is no UL-SCH on the target PUSCH, the MAC generates a MAC padding PDU.

Step 23: the PHY layer informs the MAC layer of UCI multiplexing information (i.e., the content in step 12), and the MAC layer generates a MAC PDU according to the UCI multiplexing information.

Step 24: and if the target PUCCH resource conflicts with at least one PUSCH on one or more carriers, the MAC layer determines the resource of the target PUSCH for carrying UCI in the at least one PUSCH according to the UCI on PUSCH multiplexing rule.

Step 25: the MAC generates a PDU for the target PUSCH, and if the UL-SCH does not exist, a padding PDU is generated.

Step 26: and mapping UCI on the target PUSCH.

Step 27: and mapping (padding) data on the target PUSCH.

It should be noted that, in this embodiment, the execution sequence between the step 26 and the step 27 is not limited, and the step 26 may be executed first and then the step 27 is executed (i.e., the UCI mapping is performed first and then the data mapping is performed), or the step 27 may be executed first and then the step 26 is executed (i.e., the data mapping is performed first and then the UCI mapping is performed).

Example 3:

in case that the UE enables a PUSCH UL blanking function, if the UE receives one or more UL grants, schedules at least one PUSCH on one or more carriers, and the UE receives one or more DL grants, schedules one or more PUCCHs carrying UCI, the UE determines transmission of UCI according to the following steps:

step 31: decoding the DL grant and/or the UL grant.

Step 32: the PHY layer informs the MAC layer after step 31 that the one or more PUCCHs carrying the UCI collide with at least one PUSCH on the one or more carriers.

Step 33: and the MAC generates a MAC PDU for the first PUSCH (set) with conflict according to the UCI multiplexing information.

Step 34: if there is no UL-SCH, the MAC generates a padding PDU.

Step 35: and if a plurality of PUCCHs exist, the PHY layer determines the resources of a target PUCCH carrying the UCI according to the multiplexing rule of the UCI on PUCCH.

Step 36: and if the target PUCCH resources conflict with at least one PUSCH on one or more carriers, the PHY layer determines the resources of the target PUSCH for carrying UCI in the at least one PUSCH according to a UCI on PUSCH multiplexing rule.

Step 37: if the target PUSCH has the UL-SCH, mapping of UCI and data (data) is carried out on the target PUSCH.

Step 38: otherwise, mapping UCI and padding data on the target PUSCH.

Step 39: and if the target PUSCH does not belong to the first PUSCH (set), mapping (padding) data on the first PUSCH (set).

Step 40: if one PUSCH in the first PUSCH (set) has no data, mapping of padding data is carried out.

It should be noted that, in this embodiment, the execution order of the UCI mapping and the data mapping is not limited, and the UCI mapping may be performed first and then the data mapping is performed, or the data mapping may be performed first and then the UCI mapping is performed.
