Description

Transmission method, device and storage medium for collision between uplink channels

Technical Field

The present application relates to the field of communications technologies, and in particular, to a method and apparatus for transmitting collision between uplink channels, and a storage medium.

Background

In a Random Access (RA) procedure, when an Uplink is originally in a synchronous state, a terminal may have a Physical Uplink control channel (PUCCH, physical Uplink Control CHannel) transmission or a Physical Uplink shared channel (PUSCH, physical Uplink SHARED CHANNEL) transmission carrying Uplink control information (UCI, uplink Control Information) on a cell performing the RA procedure, and the PUCCH and the PUSCH carrying UCI may collide with the PUSCH in the RA procedure.

In the prior art, no transmission scheme is defined for this scenario. If UCI on PUCCH is transferred to PUSCH in RA for transmission, the base station cannot expect what type of UCI is carried on PUSCH and what number of UCI bits is carried on PUSCH when it is not known which UE is transmitting PUSCH in RA, and therefore, PUSCH in RA cannot be received correctly, resulting in failure of RA. When collision occurs between uplink channels, how to transmit information is a technical problem to be solved.

Detailed Description

In a new wireless communication system (5G NR,5Generation New RAT), a Terminal (Terminal, also called User Equipment, UE, user Equipment) may perform Random Access for a plurality of reasons, when a contention-based Random Access is used, there may be a collision (e.g., overlap in time domain) between a Physical Uplink Shared Channel (PUSCH) SHARED CHANNEL transmission in a Random Access procedure and other Uplink channels carrying Uplink control information (UCI, uplink Control Information), and when a collision between a PUSCH in a Random Access procedure and an Uplink channel carrying UCI occurs, how to perform transmission has not been clear.

1) Random access procedure in 5G NR

When the UE goes out of step in uplink, or uplink data arrives but no scheduling request (SR, scheduling Request) is configured or the maximum number of transmissions or cell handover or initial access system (radio resource control (RRC, radio Resource Control) connection establishment or reestablishment) is reached, the terminal needs to perform RA, and uplink synchronization is achieved or uplink data resource request or access system is performed through RA procedure. RA procedures fall into two categories: a first Type (Type 1) RA procedure and a second Type (Type 2) RA procedure.

Fig. 1 is a schematic diagram of a first type RA procedure, which is a 4-step RA as shown in fig. 1. The Message (Msg, message) 1 is a process of sending a preamble sequence by the terminal, specifically, sent through a Physical Random Access Channel (PRACH) ACCESS CHANNEL, and the base station may calculate a time advance (TA, TIMING ADVANCE) adjustment value of the terminal according to the received preamble; msg2 is a process that a base station sends a Random Access response (RAR, random Access Response) to a terminal, specifically, a physical downlink shared channel (PDSCH, physical Downlink SHARED CHANNEL) carrying the RAR is scheduled by a physical downlink control channel (PDCCH, physical Downlink Control CHannel) scrambled by a Random Access radio network temporary identifier (RA-RNTI, random Access-Radio Network Temporary Identifier), wherein the RAR carries at least one uplink scheduling grant (UL grant) and TA adjustment value for scheduling Msg3 transmission, because the UL grant is carried in the RAR and may also be referred to as a RAR UL grant; msg3 is scheduling based on RAR UL grant, and performs a PUSCH transmission process, wherein the PUSCH can carry relevant information aiming at different RA purposes to help a base station obtain UE information and perform contention resolution, and when a terminal has a Cell radio network temporary identifier (C-RNTI, cell-Radio Network Temporary Identifier), the PUSCH can carry the C-RNTI to indicate which terminal is the PUSCH transmission; msg4 is a contention resolution procedure in which a PDSCH is scheduled to a terminal through a PDCCH to help the terminal identify whether its RA procedure is successful.

Fig. 2 is a schematic diagram of a second RA procedure, which is a 2-step RA, as shown in fig. 2. The Msg a includes PRACH and Physical Uplink SHARED CHANNEL (PUSCH) transmission at the same time, and when the terminal has a Cell radio network temporary identifier (C-RNTI, cell-Radio Network Temporary Identifier), the PUSCH may carry the C-RNTI to indicate which terminal is the PUSCH transmission; msg B is a comprehensive step of RAR and contention resolution. The second class RA compresses multiple steps in the RA procedure relative to the first class RA, enabling a faster RA procedure. A typical application scenario of the second class RA is for small data packet (SMALL DATA) transmission, and the SR process can be skipped to directly carry out uplink transmission, thereby realizing rapid small data packet transmission.

Each class of RA procedure may be performed in either a contention (CBRA, contention Based RA) or non-contention (CFRA, contention Free RA) manner. The CBRA, i.e. the terminal may be randomly selected when selecting the preamble sequence in the first class RA and the second class RA, and may also be randomly selected on the PRACH resources configured by the system, so that it may occur that multiple terminals select the same preamble sequence and/or the same PRACH resources to perform RA, and when the base station receives Msg1 or Msg a, it may not be able to determine which UE or UEs have transmitted the preamble, so before Msg3 in the first class RA and PUSCH in Msg a in the second class RA, the base station may not know which UE is transmitting, and needs to perform contention resolution through subsequent Msg 4. The CFRA is implemented by configuring a specific preamble sequence and a specific PRACH resource of the terminal by the base station, so that when the base station receives the preamble, it can identify which UE transmits, and thus identify from which UE the PUSCH comes.

2) UCI transmission in 5G NR

The uplink control Information (UCI, uplink Control Information) includes hybrid automatic repeat request acknowledgement (HARQ-ACK, hybrid Automatic Repeat request-ACKnowledgment), channel state Information (CSI, channel State Information), scheduling request (SR, scheduling Request), and the like. Wherein, HARQ-ACK is a generic term of positive acknowledgement (ACK, ACKnowledgment) and negative acknowledgement (NACK, non-ACKnowledgment) for feeding back to PDSCH or PDCCH (also called SPS PDSCH RELEASE) indicating release of Semi-persistent scheduling (SPS, semi-PERSISTENT SCHEDULING) resources, informing the base station of whether PDSCH or PDCCH indicating release of SPS PDSCH is received correctly; the CSI is used to feed back the downlink channel quality, so as to help the base station to perform downlink scheduling better, for example, select and configure appropriate RB resources according to the modulation coding scheme (MCS, modulation and Coding Scheme) performed by the CSI; the SR is used for requesting a base station for a transmission resource of a Physical Uplink Shared Channel (PUSCH) SHARED CHANNEL carrying Uplink traffic when the terminal has the Uplink traffic to transmit.

HARQ-ACK may be determined for HARQ-ACK feedback of the SPS PDSCH, i.e., semi-static HARQ-ACK feedback, transmitted on PUCCH resources pre-configured for SPS by higher layer signaling, and the time slot or sub-slot in which the HARQ-ACK feedback is transmitted is also relatively fixed, according to the transmission position of the SPS PDSCH and a predetermined feedback timing (i.e., K1, which is used to represent the interval between the time slot or sub-slot in which the PDSCH or PDCCH indicating SPS resource release is transmitted and the time slot or sub-slot in which the HARQ-ACK transmission is located, in units of time slot or sub-slot), this K1 may be the only one K1 value (i.e., RRC includes a feedback timing indication field in PDCCH if multiple K1 values are pre-configured), and if RRC only one K1 value is configured, the feedback timing indication field is not included in PDCCH, and this configured K1 value is directly used. The HARQ-ACK may also be feedback for PDSCH scheduled by PDCCH or PDCCH indicating SPS resource release, where the PUCCH resource carrying HARQ-ACK is determined by the PUCCH resource indication field in PDCCH, and the feedback timing may also be notified by the feedback timing indication field in PDCCH (of course, K1 value of one RRC configuration may be unique), and PUCCH transmission has a dynamic transmission characteristic, that is, PUCCH carrying HARQ-ACK may occur on any one symbol in any one slot or sub-slot depending on scheduling by the base station.

The CSI includes periodic CSI, semi-persistent scheduling CSI (SP-CSI, semi-PERSISTENT CSI), and Aperiodic CSI (A-CSI, aperiodic CSI). For periodic CSI and SR, PUCCH resources for transmission are preconfigured by high layer signaling and opportunities for transmission are fixed symbol positions in fixed slots determined from the preconfigured period and offset values of the high layer signaling. Thus, periodic CSI and SR are transmitted on specific symbols that occur fixedly in specific time slots, a relatively fixed transmission scheme. For the SP-CSI and the A-CSI, the SP-CSI is activated through PDCCH (UL grant) which uses SP-CSI-RNTI scrambling and is transmitted on a PUSCH resource according to a preset period after the activation, the transmission time slot and the symbol position of the SP-CSI are relatively fixed, the PUSCH carrying the SP-CSI does not contain any uplink data (UL-SCH or TB transmission), and only the SP-CSI is contained; the A-CSI is transmitted on a PUSCH resource scheduled by the PDCCH through an A-CSI trigger indication field in the PDCCH for scheduling the PUSCH transmission, when the A-CSI is triggered, the PUSCH can carry uplink data transmission at the same time, no uplink data transmission can be carried, and whether the uplink data transmission exists or not can be determined through a specific indication field in the PDCCH.

When there is a collision between the PUCCH carrying UCI and PUSCH in the time domain (e.g., overlapping in the time domain, possibly on the same carrier, or possibly on different carriers), the UCI on the PUCCH may be transferred to the PUSCH for transmission when a specific condition (e.g., a time condition of multiplexing transmission, etc.) is satisfied, so that the PUCCH is not transmitted any more, so as to avoid simultaneous transmission of the PUCCH and PUSCH. Thus, in some cases, PUSCH may also carry UCI that would otherwise be transmitted on PUCCH.

In the RA procedure described above, when the uplink is originally in a synchronous state (e.g., RA is only to obtain uplink resources when no SR or the number of SR transmissions reaches the upper limit or the second type RA is to skip SR request procedure for small data directly), the terminal may have physical uplink control channel (PUCCH, physical Uplink Control CHannel) transmission or PUSCH transmission carrying UCI on the cell performing the RA procedure, and PUCCH and PUSCH carrying UCI may collide with PUSCH in the RA procedure (e.g., msg3 PUSCH in the first type RA procedure, msgA PUSCH in the second type RA procedure). For example, when the PUCCH is configured on the primary Cell (PCell, primary Cell) or sPCell or one Secondary Cell (SCell) transmission, an RA procedure for requesting uplink resources or an RA procedure for transmitting small data packets occurs on the PCell, at this time, because the uplink state is synchronous, uplink channels such as PUCCH and PUSCH may be normally transmitted, the base station may schedule PDSCH transmission in advance on the premise that which UE cannot be expected to perform the above RA procedure, and this PDSCH needs to transmit HARQ-ACK through PUCCH in a time slot for transmitting PUSCH in the RA procedure, or activates PUSCH transmission for carrying SP-CSI on the PCell, and SP-CSI PUSCH is transmitted in a time slot for transmitting PUSCH in the RA procedure according to its periodic requirement; at this time, the PUCCH carrying HARQ-ACK or the SP-CSI PUSCH may have symbol overlapping with the PUSCH in the RA procedure in the same slot, resulting in collision between uplink channels.

In the prior art, no transmission scheme is defined for this scenario. If UCI on PUCCH is transferred to PUSCH in RA for transmission, the base station cannot expect what type of UCI is carried on PUSCH and what number of UCI bits is carried on PUSCH when it is not known which UE is transmitting PUSCH in RA, and thus cannot correctly receive PUSCH in RA, resulting in failure of RA.

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of 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, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

Aiming at the technical problems, when an uplink channel carrying UCI collides with a first type of PUSCH, the embodiment of the application carries out transmission according to a preset rule, wherein the first type of PUSCH is the PUSCH in the random access process.

Fig. 3 is one of schematic diagrams of a transmission method for uplink channel collision provided by an embodiment of the present application, and as shown in fig. 3, an execution body of the transmission method for uplink channel collision provided by the embodiment of the present application may be a terminal. The method comprises the following steps:

Step 301, when there is an overlap between an uplink channel carrying uplink control information UCI and a first type of physical uplink shared channel PUSCH in a time domain, the terminal autonomously selects one of the channels for transmission, or selects one of the channels for transmission according to a predetermined rule, where the first type of PUSCH is PUSCH in a random access process.

Specifically, when there is an overlap between an uplink channel carrying uplink control information UCI and a first type of physical uplink shared channel PUSCH in the time domain, the terminal autonomously selects one of the channels for transmission, or selects one of the channels for transmission according to a predetermined rule without performing an operation of transferring UCI to the first type of PUSCH.

The uplink channel carrying UCI may be PUCCH and/or PUSCH.

Autonomous selection by UE means that the UE decides itself, the UE may have its own fixed decision, e.g. random selection or alternate selection or selection according to the importance of UCI and PUSCH of the first class, etc., and the selection result is not known in advance by the base station.

The first type of PUSCH is PUSCH in a random access procedure. For example, the PUSCH scheduled by the RAR UL grant in the first type random access procedure or MsgA PUSCH in the second type random access procedure may be used.

According to the transmission method for the conflict between the uplink channels, provided by the embodiment of the application, the UE autonomously selects one channel or selects one channel for transmission according to a specific rule, so that the problem that no corresponding transmission scheme is defined is solved; the multiplexing transmission of UCI on the PUSCH in the RA process is avoided, and the correct receiving of the PUSCH in the RA process by the base station is ensured; and according to the importance degree of the UCI type carried by the uplink channel, reasonable channel selection is made, and the failure probability of random access is reduced.

Based on any one of the above embodiments, when there is an overlap between the uplink channel carrying the uplink control information UCI and the first type of physical uplink shared channel PUSCH in the time domain, the UE autonomously selects one of the channels for transmission, which specifically includes:

Specifically, in the embodiment of the present application, when there is an overlap between an uplink channel carrying uplink control information UCI and a first type of physical uplink shared channel PUSCH in the time domain, the UE autonomously selects one of the channels for transmission, and specifically includes at least one of the following scenarios:

scene 1: when the PUCCH carrying UCI only overlaps with the first PUSCH in the time domain, the UE autonomously selects one of the channels and sends the channel; and/or the number of the groups of groups,

Scene 2: when the PUSCH carrying UCI and the first type PUSCH have time domain overlapping on the same carrier, the UE autonomously selects one of the channels for transmission.

It should be noted that: when the PUCCH carrying UCI overlaps with the first PUSCH only in the time domain, it means that the PUSCH overlapping with the PUCCH is only the first PUSCH, and no other PUSCH overlaps with the PUCCH.

It should be noted that: the PUSCH carrying UCI does not include the first type PUSCH, the first type PUSCH cannot carry UCI, and the PUSCH capable of carrying UCI is other PUSCHs except the first type PUSCH, such as PUSCH with PDCCH scheduling, PUSCH carrying SP-CSI, PUSCH carrying a-CSI, CG-PUSCH, and the like.

The transmission method for the conflict between the uplink channels fully considers the conflict between the uplink channels under two different conditions, improves the reliability and further reduces the failure probability of random access.

Based on any one of the above embodiments, when there is an overlap between the uplink channel carrying the uplink control information UCI and the first type of physical uplink shared channel PUSCH in the time domain, one of the channels is selected for transmission according to a predetermined rule, which specifically includes one of the following rules:

Specifically, in the embodiment of the present application, when there is only overlapping of the PUCCH carrying UCI with the first PUSCH in the time domain, UCI transfer is not performed, and one of the channels is selected for transmission according to the following predetermined rule:

According to the transmission method for the conflict between the uplink channels, when the conflict between the uplink channels occurs, one of the rules is selected to select the uplink channel for transmission, so that reliability is improved, and failure probability of random access is further reduced.

Based on any of the above embodiments, the rule 1 further comprises one of:

Specifically, in the embodiment of the present application, for rule 1, one of the following is further included:

Or if UCI carried on PUCCH at least comprises HARQ-ACK and/or SR, selecting PUCCH, discarding the first PUSCH; if UCI carried on the PUCCH is CSI, selecting a first type PUSCH, and discarding the PUCCH;

Or if the UCI carried on the PUCCH at least comprises HARQ-ACK, the UE autonomously selects one of the channels for transmission; if UCI carried on PUCCH is CSI and/or SR, selecting a first type PUSCH, and discarding PUCCH;

or if UCI carried on PUCCH at least comprises HARQ-ACK, selecting PUCCH, discarding the first PUSCH; if UCI carried on the PUCCH is CSI and/or SR, selecting a first type PUSCH, and discarding the PUCCH.

According to the transmission method for the conflict between the uplink channels, when the conflict between the uplink channels occurs, the UCI type carried by the PUCCH is selected, so that the reliability is improved, and the failure probability of random access is further reduced.

Based on any of the above embodiments, the rule 4 further comprises:

Specifically, in the embodiment of the present application, for rule 4, further comprising:

A choice is made as to whether a Transport Block (TB, transport Block), which may also be referred to as Uplink shared channel (UL-SCH, uplink SHARED CHANNEL), is generated according to the first type of PUSCH (i.e. whether the medium access control (MAC, medium Access Control) of the UE sends protocol data units (PDU, protocol Data Unit) to this PUSCH, if a PDU is sent, the PDU is mapped to a TB in the physical layer, in order to generate a TB, if no PDU is sent, no TB is generated):

When a first type PUSCH generates a TB (i.e., the media access control (MAC, medium Access Control) of the UE sends a protocol data unit (PDU, protocol Data Unit) to this PUSCH, the PDU is mapped to the TB at the physical layer), the above rules 1-3 are further re-used; otherwise, selecting PUCCH, discarding the first type PUSCH.

According to the transmission method for the conflict between the uplink channels, when the conflict between the uplink channels occurs, the transmission block is selected according to whether the first PUSCH generates or not, reliability is improved, and failure probability of random access is further reduced.

Based on any one of the above embodiments, when there is an overlap between the uplink channel carrying the uplink control information UCI and the first type of physical uplink shared channel PUSCH in the time domain, selecting one of the channels for transmission according to a predetermined rule, which specifically includes:

It should be noted that: the first type of PUSCH is not used as a candidate PUSCH for carrying UCI on the PUCCH, i.e. the UCI is not supported to be transmitted on the first type of PUSCH, then, according to the prior art, one PUSCH is selected as a target PUSCH from PUSCHs overlapping with the PUCCH except the first type of PUSCH at this time, and is used for carrying UCI on the PUCCH; in this process, it is not necessary to determine whether a time condition of multiplexing transmission is satisfied between the first PUSCH and the PUCCH (the time condition is a time calculated according to a specific formula predefined in the prior art, and it is necessary to satisfy these time conditions between the first symbol of the earliest channel in the PUCCH and the PUSCH and the PDCCH corresponding to the PUCCH, the PDSCH corresponding to the PUCCH, or SPS PDSCH RELEASE, so as to transfer UCI on the PUCCH to the target PUSCH).

According to the transmission method for the conflict between the uplink channels, when the conflict of the uplink channels occurs, UCI on the PUCCH is transferred to the selected PUSCH for transmission, so that the reliability is improved, and the failure probability of random access is further reduced.

Based on any of the above embodiments, further comprising: and the first type PUSCH and the target PUSCH are respectively transmitted on different carriers or on a symbol set which is not overlapped in the time domain on the same carrier.

Specifically, in the embodiment of the present application, the selected PUSCH and the PUSCH of the first type are transmitted on different carriers, or on a symbol set that does not overlap in time domain on the same carrier.

The first type PUSCH does not need to satisfy the definition of the time condition of multiplexing with the PUCCH, i.e. the UE does not need to determine whether the time condition of multiplexing between the first type PUSCH and the PUCCH is satisfied.

According to the transmission method for the conflict between the uplink channels, when the conflict of the uplink channels occurs, UCI on the PUCCH is transferred to the selected PUSCH for transmission, the first type PUSCH and the selected PUSCH are respectively transmitted on different carriers or on non-overlapping symbol sets of the time domain on the same carrier, so that the reliability is improved, and the failure probability of random access is further reduced.

Specifically, in the embodiment of the present application, when there is time domain overlapping between PUSCH carrying UCI and PUSCH of the first type on the same carrier, one of the channels is selected for transmission according to the following predetermined rule:

Based on any of the above embodiments, the rule 5 further comprises one of the following:

Specifically, in the embodiment of the present application, for rule 5, one of the following is further included:

If UCI carried on the PUSCH at least comprises A-CSI, the UE autonomously selects one of the channels for transmission; if UCI carried on the PUSCH is CSI, selecting a first type of PUSCH, and discarding the PUCCH;

Or if the UCI carried on PUSCH includes at least a-CSI and PUSCH includes TB transmissions, the UE autonomously selects one of the channel transmissions; if UCI carried on PUSCH is SP-CSI or does not contain TB transmission, selecting a first type PUSCH, and discarding PUCCH;

Or if the UCI carried on the PUSCH at least comprises the A-CSI and the PUSCH comprises the TB transmission, selecting the PUSCH carrying the UCI, and discarding the first type of PUSCH; if UCI carried on PUSCH is SP-CSI or does not contain TB transmission, selecting a first type PUSCH, and discarding PUCCH;

Or if the UCI carried on the PUSCH at least comprises the A-CSI and the PUSCH does not contain the TB transmission, selecting the PUSCH carrying the UCI, and discarding the first type of PUSCH; and if UCI carried on the PUSCH is SP-CSI or contains TB transmission, selecting a first type of PUSCH, and discarding the PUCCH.

According to the transmission method for the conflict between the uplink channels, when the conflict between the uplink channels occurs, one of the channels is selected to transmit according to the UCI type borne by the PUSCH, so that the reliability is improved, and the failure probability of random access is further reduced.

Based on any of the above embodiments, the rule 8 further comprises:

Specifically, in the embodiment of the present application, if the PUSCH carrying UCI is a PUSCH scheduled to include a TB transmission (e.g., a fallback DCI scheduled, i.e., a PDCCH transmitted using a fallback DCI, or a non-fallback DCI scheduled and an indication field in the DCI indicates that there is an UL-SCH, a fallback DCI, e.g., DCI formats 0-0, a non-fallback DCI, e.g., DCI formats 0-1, 0-2, etc.), the UE selects to transmit a PUSCH that generates a TB (i.e., the MAC of the UE sends a PDU to this PUSCH, the PDU is mapped to a TB at the physical layer), and does not transmit a PUSCH that does not generate a TB.

According to the transmission method for the conflict between the uplink channels, when the conflict of the uplink channels occurs, the PUSCH carrying the UCI is selected for the PUSCH which is scheduled to contain the TB for transmission, so that the reliability is improved, and the failure probability of random access is further reduced.

Based on any one of the above embodiments, the first type PUSCH includes a PUSCH scheduled by a random access response permission RAR grant, retransmission of an Msg3 PUSCH, retransmission of a PUSCH in a second type random access, and a PUSCH in a second type random access; and/or the random access procedure is a contention-based random access procedure.

Specifically, in the embodiment of the present application, the first type PUSCH includes a PUSCH scheduled by RAR grant, retransmission of Msg3 PUSCH, retransmission of PUSCH in the second type random access, and PUSCH in the second type random access; and/or the random access procedure is a contention-based random access procedure.

The PUSCH scheduled by the RAR grant is msg3 PUSCH in the first type of random access.

PUSCH in the second type of random access is PUSCH in msg a in the second type of random access.

If retransmission of Msg3 PUSCH, that is, initial PUSCH transmission by RAR grant scheduling fails, PUSCH retransmission is scheduled by DCI dynamic scheduling (scrambling using TC-RNTI) for this PUSCH.

According to the transmission method for the conflict between uplink channels, which is provided by the embodiment of the application, the first type of PUSCH comprises the PUSCH scheduled by the RAR grant, the retransmission of the Msg3 PUSCH, the retransmission of the PUSCH in the second type of random access and the retransmission of the PUSCH in the second type of random access, so that the reliability is improved, and the failure probability of the random access is further reduced.

What needs to be described is: the above embodiments can be generalized to three cases:

Case 1: when there is overlap in time domain between PUCCH and only the first type PUSCH: the UE autonomously selects one of the channels for transmission or selects one of the channels for transmission according to a predetermined rule.

Case 2: when there is overlap in time domain between the PUCCH and a plurality of PUSCHs including the first type PUSCH: and selecting one PUSCH from the PUSCHs except the first type of PUSCHs, transferring UCI on the PUCCH to the selected PUSCH for transmission, and not transmitting the PUCCH.

Case 3: when the PUSCH carrying UCI and the first type PUSCH have time domain overlapping on the same carrier, the UE autonomously selects one of the channels for transmission, or selects one of the channels for transmission according to a preset rule.

For case 1 and case 2, uci may be at least one of HARQ-ACK, SR, periodic CSI.

For case 3, the uci may be at least one of SP-CSI, a-CSI; at least one of HARQ-ACK, SR, periodic CSI may also be included if UCI on PUSCH is originally transferred from PUCCH.

When the contention random access is adopted, processing is performed according to the mode; when non-contention random access is adopted, the processing in the above manner is not needed, namely under the non-contention random access, for the cases 1 and 2, the first type PUSCH under the non-contention random access can also be used for carrying UCI on PUCCH, one PUSCH can be selected from all PUSCHs overlapped with PUCCH to carry UCI on PUCCH according to the manner of the prior art, special treatment of the first type PUSCH is not needed, and for the case 3, the ue does not expect the above overlapping situation to occur, namely the base station avoids the above overlapping situation to occur through scheduling or configuration; of course, the above limitation may be omitted, and the first PUSCH in any random access case is considered to be processed in the above manner.

Based on any of the above embodiments, fig. 4 is a schematic diagram of a transmission method of uplink channel collision according to the embodiment of the present application, and as shown in fig. 4, the execution body of the transmission method of uplink channel collision according to the embodiment of the present application may be a base station. The method comprises the following steps:

In step 401, when there is an overlap between an uplink channel carrying uplink control information UCI and a first type of physical uplink shared channel PUSCH in the time domain, determining that the terminal UE autonomously selects one of the channels for transmission, or determining that the UE selects one of the channels for transmission according to a predetermined rule, where the first type of PUSCH is a PUSCH in a random access process.

Specifically, the method for transmitting collision between uplink channels provided in the embodiment of the present application is the same as the method described in the foregoing corresponding embodiment, and can achieve the same technical effects, and the difference is only that the execution main body is different, so that the parts and beneficial effects of the embodiment, which are the same as those of the foregoing corresponding method embodiment, are not specifically repeated.

Based on any of the above embodiments, when there is an overlap between the uplink channel carrying the uplink control information UCI and the first type of physical uplink shared channel PUSCH in the time domain, determining that the UE autonomously selects one of the channels for transmission specifically includes:

Based on any one of the above embodiments, when there is an overlap between the uplink channel carrying the uplink control information UCI and the first type of physical uplink shared channel PUSCH in the time domain, it is determined that the UE selects one of the channels for transmission according to a predetermined rule, and the method specifically includes one of the following rules:

Based on any of the above embodiments, the rule 1 further comprises one of:

Based on any of the above embodiments, the rule 4 further comprises:

Based on any of the foregoing embodiments, when there is an overlap between an uplink channel carrying uplink control information UCI and a first type of physical uplink shared channel PUSCH in the time domain, determining that the UE selects one of the channels for transmission according to a predetermined rule specifically includes:

Based on any of the above embodiments, the rule 8 further comprises:

Based on any one of the above embodiments, the first type PUSCH includes a PUSCH scheduled by RAR grant, retransmission of Msg3 PUSCH, retransmission of PUSCH in the second type random access, and PUSCH in the second type random access; and/or the random access procedure is a contention-based random access procedure.

Based on any of the above embodiments, when there is an overlap between an uplink channel carrying uplink control information UCI and a first type of physical uplink shared channel PUSCH in the time domain, determining that the UE autonomously selects one of the channels for transmission, or determining that the UE selects one of the channels for transmission according to a predetermined rule, specifically includes:

Specifically, in the embodiment of the present application:

When the PUCCH is overlapped with the first PUSCH in the time domain, for the case that the terminal selects one of the channels according to a predetermined rule for transmission, when the base station side knows which UE the first PUSCH is transmitted (for example, when CFRA is used), the base station can only detect the selected channel according to the rule, not detect the discarded channel, when the base station side does not know which UE the first PUSCH is transmitted (for example, when CBRA is used), the base station side blindly detects the PUCCH and the first PUSCH for the terminal to be transmitted; when receiving the first type PUSCH, the reception is performed in such a way that no UCI is transmitted thereon.

When the PUCCH only overlaps with the first PUSCH in the time domain, aiming at the situation that the terminal autonomously selects one channel for transmission, namely the UE randomly selects one channel from the PUCCH and the first PUSCH for transmission, the base station side blindly detects the PUCCH and the first PUSCH for the terminal needing to send the PUCCH, and when receiving the first PUSCH, the base station side receives the PUCCH according to the mode without UCI transmitted on the PUCCH.

When there is time domain overlapping between the PUSCH carrying UCI and the first type PUSCH on the same carrier, aiming at the situation that a terminal selects one of channels for transmission according to a predetermined rule, when a base station side knows which UE the first type PUSCH is transmitted (for example, when CFRA is adopted), the base station can only detect the selected channel according to the rule, but not detect the discarded channel, when the base station side does not know which UE the first type PUSCH is transmitted (for example, when CBRA is adopted), the base station side blindly detects the PUSCH carrying UCI and the first type PUSCH for a PUSCH terminal which needs to transmit the UCI; when receiving the first type PUSCH, the reception is performed in such a way that no UCI is transmitted thereon.

When the PUSCH carrying UCI and the first type of PUSCH are overlapped in the same carrier, aiming at the situation that a terminal autonomously selects one channel for transmission, namely, the UE randomly selects one from the PUSCH carrying UCI and the first type of PUSCH for transmission, a base station side blindly detects the PUSCH carrying UCI and the first type of PUSCH of the terminal which needs to send the PUSCH carrying UCI; when receiving the first type PUSCH, the reception is performed in such a way that no UCI is transmitted thereon.

The method in each of the above embodiments is further described in three specific examples:

Example 1:

Fig. 5 is one of diagrams of uplink channel collision provided by the embodiment of the present application, as shown in fig. 5, assuming that a UE sends msg1 in a certain time slot of a PCell, a contention mode is adopted for random access, and a PUSCH scheduled by an RAR UL grant is determined according to a received msg2 and a timing relationship, and a base station does not know that the UE enters a random access procedure, schedules a PDSCH transmission in a time slot before the time slot n+8, and needs HARQ-ACK feedback in the time slot n+8 through a PUCCH, so that a collision (that is, there is an overlap in transmission time) between the PUCCH carrying the HARQ-ACK and the PUSCH scheduled by the RAR UL grant occurs, and the method according to the present application:

UE side:

if rule 1 is employed: assuming that the HARQ-ACK is prioritized, the UE selects a PUCCH bearing the HAR Q-ACK, or selects a PUCCH bearing the HARQ-ACK when the UE autonomously selects one transmission from PUCCH and PUSCH scheduled by the RAR UL grant; the UE transmits the PUCCH carrying the HARQ-ACK in the time slot n+8, and does not transmit the PUSCH scheduled by the RA R UL grant;

If rule 2 is employed: always selecting the PUSCH scheduled by the RAR UL grant, and not transmitting the PUCCH; the UE transmits the PUSCH scheduled by the RAR UL grant in the time slot n+8, and does not transmit the PUCCH carrying the HARQ-ACK;

if rule 3 is employed: always select PUCCH, PUSCH scheduled by RAR UL grant is not transmitted; the UE transmits the PUCCH carrying the HARQ-ACK in the time slot n+8, and does not transmit the PUSCH scheduled by the RAR UL grant;

If rule 4 is employed: firstly determining whether the PUSCH scheduled by the RAR UL grant generates a TB, if the TB is generated, determining which channel to select by using one of the rules 1-3, and if the TB is not generated, selecting the PUCCH and not transmitting the PUSCH scheduled by the RAR UL grant;

If the UE autonomously selects, the UE may autonomously select one transmission from the PUSCH scheduled by the PUCCH and the RAR UL grant, for example, the UE selects the PUSCH scheduled by the RAR UL grant, and the UE transmits only the PUSCH scheduled by the RAR UL grant in the slot n+8, and does not transmit the PUCCH;

base station side:

In the contention mode, before the PUSCH scheduled by the RAR UL grant is not received, it is not known from which UE this PUSCH comes from, nor is it known whether the MAC of the UE issues a PDU for the PUSCH scheduled by the RAR UL grant, however, if in the UE autonomous selection mode, even in the non-contention mode, the base station does not know which channel transmission the UE has selected, the base station needs to detect the UE that originally transmitted the PUCCH in this slot on the corresponding PUCCH resource, and also needs to receive the PUSCH scheduled by the RAR UL grant indicated by the RAR UL grant in msg2 on the PUSCH resource of the terminal performing random access, and receive this PUSCH in the mode without UCI multiplexing, so that the PUSCH scheduled by the RAR UL grant can be correctly obtained.

Example 2:

Fig. 6 is a second schematic diagram of an uplink channel collision provided in the embodiment of the present application, as shown in fig. 6, assuming that a terminal is configured with 3 carriers, in the case of PCell (CC 1), as in embodiment 1 above, further, in time slot 8, there is one PUSCH overlapping with PUCCH on each of the other two scells (CC 2, 3), and the method according to the present application:

UE side:

When multiplexing transmission is considered when the PUCCH and the PUSCH overlap is not supported, the PUSCH scheduled by the RAR UL grant overlapped with the PUCCH is not considered, namely, the UE selects one PUSCH from the PUSCH overlapped with the PUCCH only on the CCs 2 and 3 according to a preset selection rule (the selection rule is the prior art, for example, according to whether the PUSCH carries A-CSI, whether the PUSCH has DCI scheduling, according to the CC number of the PUSCH and the like, and is not repeated in detail), for example, UCI on the PUSCH carried on the CC2 is selected, the UE transmits the HARQ-ACK on the PUCCH to the PUSCH on the CC2, and the PUCCL is not required to be transmitted in the Pcell, namely, the UE does not have overlapping with the PUSCH scheduled by the RAR UL grant, so that the UE can transmit the PUSCH on the CCs 1,2 and 3 respectively in a time slot n+8.

Base station side:

because the base station does not know whether there is PUSCH transmission scheduled by RAR UL grant of the UR in the time slot n+8 under the contention RA, the base station only selects one PUSCH from PUSCHs on CCs 2 and 3 according to the rule similar to the UE side described above, and determines that the PUSCH carries UCI on PUCCH, then the base station receives PUSCH on the CC2 in the mode of carrying UCI, receives PUSCH on the CC3 in the time slot n+8, does not need to receive PUCCH on the CC1, and also needs to receive PUSCH scheduled by RAR UL grant on PUSCH resources indicated to a terminal performing random access by RAR UL grant in msg2, and receives the PUSCH in the mode without UCI multiplexing, thereby correctly obtaining PUSCH scheduled by RAR UL grant.

Example 3:

Fig. 7 is a third schematic diagram of collision between uplink channels provided in the embodiment of the present application, as shown in fig. 7, assuming that a UE sends msg1 in a certain time slot of a PCell, a contention manner is adopted for random access, and a PUSCH scheduled by an RAR UL grant is determined according to a received msg2 and a timing relationship, and a base station does not know that the UE enters a random access procedure, activates an SP-CSI transmission transmitted on the PUSCH through a PDCCH in a time slot before the time slot n+8, and the time slot n+8 is a transmission opportunity of the PUSCH carrying the SP-CSI (abbreviated as SP-CSI PUSCH), then collision (that is, there is an overlap in transmission time on the same carrier) of the PUSCH carrying the SP-CSI and the PUSCH scheduled by the RAR UL grant occurs, according to the method of the present application:

UE side:

If rule 5 is employed: assuming that the SP-CSI priority is lower than the PUSCH scheduled by the RAR UL grant, the UE selects the PUSCH scheduled by the RAR UL grant, or the UE selects the PUSCH scheduled by the RAR UL grant when selecting one transmission from the master-slave SP-CSI PUSCH and the PUSCH scheduled by the RAR UL grant; the UE transmits the PUSCH scheduled by the RAR UL grant in the time slot n+8, and does not transmit the SP-CSI PUSCH;

If rule 6 is employed: the RAR UL grant scheduled PUSCH is always selected, and the SP-CSI PUSCH is not transmitted; the UE transmits the PUSCH scheduled by the RAR UL grant in the time slot n+8, and does not transmit the SP-CSI PUCCH;

If rule 7 is employed: the PUSCH bearing UCI is always selected, and the PUSCH scheduled by the RAR UL grant is not transmitted; the UE transmits the SP-CSI PUSCH in the time slot n+8, and does not transmit the PUSCH scheduled by the RAR UL grant;

If the UE autonomously selects, the UE may autonomously select one transmission from the PUSCH scheduled by the SP-CSI PUSCH and the RAR UL grant, for example, the UE selects the PUSCH scheduled by the RAR UL grant, and the UE transmits only the PUSCH scheduled by the RAR UL grant in the slot n+8, and does not transmit the SP-CSI PUSCH;

base station side:

In the contention mode, before the PUSCH scheduled by the RAR UL grant is not received, it is not known from which UE this PUSCH comes from, nor is it known whether the MAC of the UE issues a PDU for the PUSCH scheduled by the RAR UL grant, however, if in the UE autonomous selection mode, even in the non-contention mode, the base station does not know which channel transmission the UE has selected, the base station needs to detect the UE that originally transmitted the SP-CSI PUSCH in this slot on the corresponding SP-CSI PUSCH resource, and also needs to receive the PUSCH scheduled by the RAR UL grant on the PUSCH resource indicated to the terminal performing random access by the RAR UL grant in msg2, and receive this PUSCH in the mode without UCI multiplexing, so that the PUSCH scheduled by the RAR UL grant can be obtained correctly.

It should be noted that, in the above embodiments 1 and 2, only PUSCH scheduled by PUCCH and RAR grant is taken as an example in the same Cell, and when the two are transmitted in different cells, if overlapping in time occurs, the above method is also applicable; the above embodiments 1 and 2 are only exemplified by one of the modes of rule 1, and the other modes are equally applicable; in embodiments 1 and 2, only PUCCH carrying HARQ-ACK is taken as an example, if one of the CSI and SR is carried by the PUCCH, for example, the final selection result may be PUSCH scheduled by transmitting RAR UL grant, and no PUCCH carrying CSI and SR is transmitted; in the above embodiment 3, only the case where the PUSCH carrying the SP-CSI overlaps with the PUSCH scheduled by the RAR UL grant is taken as an example, and the case where the PUSCH carrying the UCI overlaps with the PUSCH scheduled by the RAR UL grant is similar, and will not be described in detail, for example, when the PUSCH carrying the SP-CSI is the PUSCH, rule 8 may be adopted in addition to the above manner: determining which of the a-CSI PUSCH and the RAR UL grant scheduled PUSCH generates the TB, transmitting only the channel where the TB is generated, e.g., determining that the RAR UL grant scheduled PUSCH generates the TB, transmitting only the RAR UL grant scheduled PUSCH, and not transmitting the a-CSI PUSCH; in the above embodiments 1 to 3, only the PUSCH scheduled by the RAR grant is taken as an example, and the PUSCH is replaced by the Msg a.

The application provides a transmission method when PUSCH and PUCCH/PUSCH carrying UCI in random access process, which selects one channel to transmit independently or selects one channel to transmit according to specific rule or selects PUSCH carrying UCI from PUCCH in non-random access process, on one hand, solves the problem that no transmission scheme is defined for the scene in the prior art, on the other hand, avoids multiplexing transmission of UCI on PUSCH in random access process, ensures correct receiving of PUSCH in random access process by base station, and on the third hand, makes reasonable channel selection according to importance degree of UCI type carried by uplink channel, and reduces failure probability of random access.
