detailed description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

The technical terms involved in the technical solutions provided by the embodiments of the present application will be explained below:

1. Time-domain overlap of transmission resources (or time-domain conflict)

Compared with the previous mobile communication system, the future 5G mobile communication system needs to adapt to more diverse scenarios and business requirements. The main scenarios of 5G include enhanced mobile broadband (eMBB), massive machine type communications (mMTC), and ultra-reliable and low latency communications (URLLC), These scenarios require high reliability, low latency, large bandwidth, and wide coverage for mobile communication systems. The UE can support different services, for example, the UE supports not only the URLLC service with low latency and high reliability, but also the eMBB service with large capacity and high speed. In a new radio technology (new radio, NR) system, since different channels can have different start symbols and lengths, the time-domain overlap of transmission resources may occur. Generally, in order to maintain the uplink single-carrier characteristic, when a time slot has multiple overlapping uplink transmission resources for transmission, the single-carrier characteristic of the UE will be destroyed, and the difference of the transmit power will cause the deterioration of the channel estimation performance. This situation is usually regarded as a conflict, and a corresponding conflict resolution needs to be designed, merging or discarding some information.

2. Upstream channel

The uplink control channel includes: physical uplink control channel (physical uplink control channel, PUCCH).

The uplink shared channel includes: physical uplink shared channel (PUSCH).

3. The UCI defined by the physical layer is multiplexed on the PUSCH

Uplink control information (eg, UCI) is transmitted on an uplink control channel (eg, PUCCH). If the terminal device is transmitting data on the uplink shared channel (eg, PUSCH), in principle, the PUCCH and the PUSCH can be sent at the same time, that is, the UCI is reserved in the PUCCH. However, this will increase the Cubic Metric; in addition, if the requirement of out-of-band transmission is to be met at a higher transmit power, and the PUSCH and PUCCH are transmitted simultaneously, the interval in the frequency domain is large (PUCCH is generally in transmitted at both ends of the frequency band), which will pose challenges for radio frequency (RF) implementation. Therefore, under normal circumstances, if the PUCCH resources that need to transmit UCI and the PUSCH resources overlap in time, and the base station will ensure that the conditions of the UCI multiplexing processing time are met when scheduling the PUSCH, the UCI will be multiplexed with the data on the PUSCH. above, avoid sending PUCCH at the same time.

4. PUCCH and PUSCH conflict handling

In NR R15, within a PUCCH group (PUCCH group), no matter whether PUCCH and PUSCH are in the same serving cell or in different serving cells, simultaneous transmission of PUCCH and PUSCH is not supported. When PUCCH and PUSCH time domain resources overlap (including partial time domain resource overlap and all time domain resource overlap), the UE will discard or combine according to corresponding rules under the condition that certain time requirements are met.

Exemplarily, if the PUCCH carrying the scheduling request (SR) and the PUSCH not carrying the uplink shared channel (UL-SCH) overlap in time domain, the UE discards the PUSCH and transmits the SR PUCCH. Or the UE multiplexes the uplink control information (uplink control information, UCI) (except SR) carried on the PUCCH into the PUSCH for transmission. For example, if the PUCCH 1 and PUSCH 2 carrying the hybrid automatic repeat request acknowledgement (HARQ-ACK) or the channel state information (CSI) overlap, the UE will ACK/CSI is multiplexed into PUSCH 2 for transmission.

Specifically, the UE first processes the time-domain resource overlap between multiple PUCCHs (if any), and the result of the processing is one or more PUCCHs with non-time-domain resources overlapping, and then the UE processes the time-domain resources between the PUCCH and the PUSCH. Overlapping, if the PUCCH only overlaps with one PUSCH, the UE multiplexes the UCI (excluding the SR) in the PUSCH. If the PUCCH only overlaps with multiple PUSCHs, the UE selects a PUSCH according to the multiplexing rules in the related art. Multiplexing, the first multiplexing rule (that is, instructing the UE to select the PUSCH for multiplexing UCI) is as follows:

Rule 1: PUSCH carrying aperiodic channel state information (Aperiodic CSI, A-CSI).

Rule 2: The PUSCH with the earliest start slot.

Rule 3: Dynamically scheduled PUSCH>Configure granted PUSCH or semi-persistent PUSCH.

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

Rule 5: PUSCH with earlier transmission symbol > PUSCH with later transmission symbol.

Exemplarily, the physical layer priority of the PUCCH is determined by the priority of the UCI carried by the PUCCH. For example, the priority of SR is configured through radio resource control (RRC), the priority of periodic CSI and semi-persistent CSI (SP-CSI) is predefined as low priority, and the priority of HARQ-ACK is determined by its corresponding DCI Indicated or determined according to the configuration of semi-persistent scheduling (SPS). The transmission priority of the PUSCH is indicated by the scheduling downlink control information (DCI) corresponding to the PUSCH, or for the PUSCH with the configuration grant, the priority is configured by the RRC.

When the time domain resources of PUCCH and PUCCH overlap or the time domain resources of PUCCH and PUSCH overlap, the UE first processes transmissions with the same priority (the rules are the same as R15), and then processes transmissions with different priorities. When a certain time requirement is met, the UE cancels transmission (or is called discarding) the uplink resources of low priority and transmits uplink resources of high priority.

5. The uplink transmission skip function defined by the MAC layer

The MAC layer defines the process that the terminal implements uplink transmission skipping (UL skipping) in the protocol TS38.321. The MAC entity will not generate a MAC PDU for the HARQ entity if the following conditions are met:

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

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

Condition 3: The MAC PDU includes zero MAC SDUs.

Condition 4: The MAC PDU contains only periodic Buffer Status Reports (BSRs) and no data is available for any Logical Channel Group (LCG), or the MAC PDUs contain only padding BSRs.

In the related art, when the UL skipping function is enabled on the uplink shared channel of the terminal device, if there is a resource conflict between the time domain resources of the uplink control channel (eg, PUCCH) and the time domain resources of the dynamically scheduled uplink shared channel, Since the PUSCH may not have data to be sent, the MAC layer generates PDUs based on whether there is data or not, and cannot generate PDUs based on whether there is UCI to be multiplexed.

Specifically, in the case of resource conflict between the time domain resources of the uplink control channel (such as PUCCH) and the time domain resources of the dynamically scheduled uplink shared channel, the terminal device may choose not to generate the PUSCH, so that the uplink control information (such as, UCI) is transmitted on the PUCCH, and the PUSCH can also be selected to be generated, so that the uplink control information is multiplexed and transmitted on the PUSCH.

In this way, the resources multiplexed by the UCI cannot be determined on the network side, and the network side cannot receive the UCI accurately. Especially when the number of carriers is large, the network side equipment needs to perform blind detection on each carrier based on the two assumptions of whether the uplink control information is multiplexed in the PUSCH of the carrier, which will increase the complexity of the network side blind detection, which is a problem for the network side. cause a greater burden.

In order to solve the above problem, the embodiments of the present application provide an uplink transmission method, apparatus, and device. Under the condition that the terminal device enables the uplink transmission skip function, if the time domain resources of at least one uplink shared channel are different from the time domain resources of at least one uplink transmission The time domain resources of the control channel overlap, and the MAC layer can generate a MAC PDU according to any one of the following processing methods: Mode 1, if the MAC layer learns that the time domain resources of the above-mentioned uplink shared channel overlap with the above-mentioned time domain resources of the uplink control channel , then the MAC PDU is generated; in mode 2, the MAC PDU is generated according to the multiplexing information notified to the MAC layer by the physical layer; wherein, at least one uplink control information is carried on the at least one uplink control channel. In this way, in the case of conflict between the uplink shared channel and the uplink control channel, the MAC PDU can be generated through the MAC layer, so that the terminal device can support the uplink control information carried on the uplink control channel even in the absence of data transmission. It is multiplexed onto the uplink shared channel with the uplink transmission skip function enabled, so that the network side device can accurately determine the resources of the uplink control channel multiplexing without blind detection of two hypotheses, which reduces the blind detection on the network side. The complexity of the system improves the energy efficiency of system communication.

Optionally, in this embodiment of the present application, the foregoing multiplexing information may also be used to indicate a target uplink shared channel. The at least one uplink shared channel is an uplink shared channel used to carry the uplink control information of the at least one uplink control channel. Further, at this time, the MAC layer may not need the physical layer to notify that there is currently a conflict between the uplink control channel and the above-mentioned 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 this embodiment of the present application, the foregoing multiplexing information is used to indicate at least one of the following:

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

Further optionally, in the embodiment of the present application, in the case that the scheduling grant is a downlink scheduling grant, the downlink scheduling grant is DCI for scheduling part or all of the uplink control channels in the at least one uplink control channel.

Exemplarily, when the terminal device has no data, a MAC padding PDU (MAC padding PDU) is generated. The terminal device has no data, specifically, there is no data in the logical channel group (Logical channel group) corresponding to the PUSCH.

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

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

Further optionally, in the embodiment of the present application, the uplink transmission method provided by the embodiment of the present application may further include the following step A1:

Step A1: On the target carrier, the above-mentioned uplink transmission skip function is prohibited from being enabled.

Wherein, the above-mentioned target carrier is: the carrier where the uplink shared channel overlaps with the time domain resource of the uplink control channel.

Exemplarily, when at least one PUCCH and PUSCH overlap in time, the UE disables the PUSCH UL skipping function. Further, on the carrier where the PUSCH conflicting with the PUCCH is located, the PUSCH UL skipping function is prohibited from being enabled.

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

Step B1: When the at least one uplink control channel includes multiple uplink control channels, the physical layer or the MAC layer determines the target uplink control channel from the multiple uplink control channels according to the first multiplexing rule.

Step B2: When the at least one uplink shared channel includes multiple uplink shared channels, the physical layer or the MAC layer determines the target uplink shared channel from the plurality of uplink shared channels according to the second multiplexing rule.

Step B3: In the case that the at least one uplink shared channel includes multiple uplink shared channels, and the time domain resources of the target uplink control channel overlap with the time domain resources of the multiple uplink shared channels, the physical layer or the MAC layer is based on the first step. The two multiplexing rules and the above-mentioned target uplink control channel determine the above-mentioned target uplink shared channel from the above-mentioned multiple uplink shared channels.

Exemplarily, the above-mentioned first multiplexing rule may be a PUCCH multiplexing rule of UCI on PUCCH.

In an example, the multiplexing rule of HARQ-ACK on PUCCH and the multiplexing rule of Scheduling request (SR) on PUCCH are 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: SR and CSI are transmitted on the PUCCH of CSI, [log2(K+1)] bits are preset before the periodic/semi-static CSI information bits, and indicate the corresponding SR status in the SR resource Id in ascending order (active or inactive).

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

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

Exemplarily, for the above step B2, when the at least one uplink shared channel includes a plurality of uplink shared channels, and the plurality of uplink shared channels are located on a single carrier, the target uplink shared channel is determined based on at least one of the following: of:

The uplink shared channel with the earliest start time domain position among the above-mentioned multiple uplink shared channels;

The uplink shared channel for which aperiodic CSI reporting is triggered in the above-mentioned multiple uplink shared channels;

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

The physical layer notifies the MAC layer whether each of the multiple uplink shared channels multiplexes the uplink control information.

For example, taking the uplink shared channel as the PUSCH as an example, when there is a single carrier and there are multiple PUSCHs, the PHY layer needs to determine the target PUSCH carrying the UCI according to the second multiplexing rule. The specific multiplexing methods include: multiplexing mode 1: the target PUSCH is the PUSCH with the earliest start time among the multiple PUSCHs on the carrier; multiplexing mode 2: the target PUSCH is the triggering aperiodic among multiple PUSCHs on the carrier PUSCH for CSI reporting (Aperiodic-CSI, A-CSI).

Exemplarily, for the above-mentioned step B2, in the case that the above-mentioned at least one uplink shared channel includes multiple uplink shared channels, and the above-mentioned multiple uplink shared channels are located on multiple carriers, the above-mentioned target uplink shared channel satisfies at least one of the following:

The uplink shared channel with the earliest start time domain position among the multiple uplink shared channels on the first carrier;

An uplink shared channel for which aperiodic CSI reporting is triggered among the multiple uplink shared channels on the first carrier;

an uplink shared channel on the second carrier;

Uplink control channel on the third carrier.

The above-mentioned first carrier is a carrier whose number satisfies a predetermined condition (for example, the number is the smallest) among the above-mentioned multiple carriers; the above-mentioned second carrier is an uplink scheduled carrier among the above-mentioned multiple carriers and whose number satisfies the above-mentioned predetermined condition; the above-mentioned third carrier The carrier is a carrier for which aperiodic CSI reporting is triggered and whose number satisfies the above-mentioned predetermined condition among the above-mentioned multiple carriers.

For example, taking the uplink shared channel as PUSCH as an example, when there are multiple carriers and there are multiple PUSCHs, the PHY layer needs to determine the target PUSCH carrying the UCI and the carrier where the target PUSCH is located according to the second multiplexing rule.
