Method and device for sending or receiving feedback information

Technical Field

The present application relates to the field of communications, and in particular, to a method and an apparatus for sending or receiving feedback information.

Background

A fifth generation (5th generation, 5G) communication system supports two-step random access. In the two-step random access, the network device may send a message including multiple Random Access Responses (RARs), where the RARs belong to multiple terminal devices, and after receiving the message, the terminal devices need to send feedback information for the RARs, so that the network device determines whether to retransmit an RAR based on the feedback information.

The network device may indicate, to the terminal device, an uplink feedback resource required for sending the feedback information through Downlink Control Information (DCI), where the uplink feedback resource is, for example, a Physical Uplink Control Channel (PUCCH). However, currently, one DCI can only indicate one uplink feedback resource, and multiple terminal devices cannot send feedback information through one feedback resource, so how to indicate uplink feedback resources for multiple terminal devices in two-step random access is a problem that needs to be solved currently.

Fig. 1 is a schematic diagram of a possible wireless communication system to which an embodiment of the present application is applied. The wireless communication system 100 may include a network device 110. Network device 110 may provide communication coverage for a particular geographic area and may communicate with terminal devices located within that coverage area.

Optionally, the Network device 100 may be a Base Transceiver Station (BTS) in a GSM system or a CDMA system, a Base Station (NodeB, NB) in a WCDMA system, an evolved Node B (eNB or eNodeB) in an LTE system, or a wireless controller in a Cloud Radio Access Network (CRAN), or a Network device in a relay Station, an Access point, a vehicle-mounted device, a wearable device, a future Network side device, or a future evolved Public Land Mobile Network (PLMN), or the like.

The wireless communication system 100 also includes at least one terminal device 120 located within the coverage area of the network device 110.

The terminal device 120 may be mobile or stationary.

Alternatively, terminal equipment 120 may refer to User Equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a user terminal, a wireless communication device, a user agent, or a user device. The terminal device may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with Wireless communication function, a computing device or other processing device connected to a Wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a 5G Network or a terminal device in a Public Land Mobile Network (PLMN) for future evolution, and the like, which are not limited in this embodiment. Optionally, a Device to Device (D2D) communication may be performed between the terminal devices 120.

Network device 110 may serve a cell through which terminal device 120 communicates with network device 110 using transmission resources, e.g., frequency domain resources, or spectrum resources, used by the cell. The cell may be a cell corresponding to the network device 110, and the cell may belong to a macro base station or a base station corresponding to a Small cell (Small cell), where the Small cell may include: urban cells (Metro cells), Micro cells (Micro cells), Pico cells (Pico cells), Femto cells (Femto cells), and the like, and the small cells have the characteristics of small coverage area and low transmission power, and are suitable for providing high-rate data transmission services.

Fig. 1 exemplarily shows one network device and two terminal devices, but the present application is not limited thereto. The wireless communication system 100 may include a plurality of network devices and may include other numbers of terminal devices within the coverage area of each network device. The wireless communication system 100 may further include other network entities such as a network controller, a mobility management entity, and the like.

The communication system 100 is only an example, and a communication system to which the present application is applied is not limited thereto, and for example, the number of network devices and terminal devices included in the communication system 100 may be other numbers. The following describes the technical solution of the present application, taking the example that the communication system 100 is a 5G communication system. For the sake of brevity, the terminal devices and network devices in the following are not accompanied by reference numerals.

Random access is the process by which a terminal device attempts to access a communication network. After the cell search procedure, the terminal device has acquired downlink synchronization with the network device (which may also be referred to as a "cell"), and thus the terminal device is able to receive downlink data. However, the terminal device needs to acquire uplink synchronization with the network device in order to perform uplink transmission. The terminal equipment can establish connection with the network equipment through a random access process and acquire uplink synchronization. That is, through random access, the terminal device may obtain uplink synchronization and obtain a cell radio network temporary identity (C-RNTI), which is a unique identifier allocated to the terminal device by the network device. Therefore, the random access can be applied not only in the initial access, but also in the case of the uplink synchronization loss of the user.

The random access procedure may typically be triggered by one of the following 6 types of triggering events:

(1) initial access (initial access).

The terminal device enters an RRC CONNECTED state (RRC _ CONNECTED) from a Radio Resource Control (RRC) IDLE state (RRC _ IDLE).

(2) Handover (handover).

When the terminal device needs to establish uplink synchronization with a new cell, random access needs to be initiated in the new cell.

(3) RRC connection re-establishment (RRC connection re-establishment).

The terminal device reestablishes the radio connection after Radio Link Failure (RLF) occurs.

(4) In the RRC connected state, when downlink data arrives, the uplink is in an "out-of-sync" state.

At this time, after the downlink data arrives, the terminal device needs to reply an Acknowledgement (ACK) or a Negative Acknowledgement (NACK).

(5) In the RRC connected state, when uplink data arrives, the uplink is in an "out-of-sync" state or there is no PUCCH resource for Scheduling Request (SR) transmission.

When uplink data reaches a state that a measurement report needs to be reported or data needs to be sent, if the uplink is in an asynchronous state, the terminal equipment can initiate a random access process; or, if the terminal device already in the uplink synchronization state is allowed to use a Random Access Channel (RACH) instead of the SR, the terminal device may initiate a random access procedure when the uplink is in the "out-of-synchronization" state.

(6) In the RRC connected state, in order to locate, a Timing Advance (TA) needs to be obtained.

In addition, random access may be triggered due to RRC active state (RRC _ INACTIVE) transition, request of Other System Information (OSI), or beam failure recovery (beam failure recovery).

Fig. 2 is a schematic diagram of 4-step random access. The flow of 4-step random access may include the following four steps:

step 1, the terminal equipment sends a message (Msg) 1.

The terminal device may send Msg1 to the network device through a Physical Random Access Channel (PRACH) to tell the network device that the terminal device initiates a random access request, where the Msg1 carries a Random Access Preamble (RAP), and the RAP may also be referred to as a preamble, a random access preamble sequence, a preamble sequence, or the like. The network device can estimate the transmission delay between the network device and the terminal device according to the Msg1 and the size of the uplink resource required by the Msg3 in step 3.

Step 2, the network device sends Msg 2.

After receiving the Msg1 sent by the terminal device, the network device sends Msg2, that is, a Random Access Response (RAR) message to the terminal device. The terminal device may monitor a Physical Downlink Control Channel (PDCCH) scrambled by a random access radio network temporary identity (RA-RNTI) in an RAR window (RAR window) to receive a Physical Downlink Shared Channel (PDSCH) scheduled by the PDCCH, where the RAR message is carried in the PDSCH. The RAR message may be scheduled by using a Downlink Control Information (DCI) format (format) 1-0.

And if the terminal equipment does not receive the RAR message replied by the network equipment in the RAR window, the random access is considered to be failed. If the terminal device successfully detects the RAR message within the RAR window and the index of the preamble carried in the RAR message is the same as the index of the preamble in Msg1, the terminal device may stop detecting the RAR message. The terminal device may descramble the RAR message using an RA-RNTI that is associated with the PRACH used by the terminal device to send Msg 1.

The RAR message may include response messages for a plurality of terminal devices that transmitted the preamble. The response message for each terminal device includes a Random Access Preamble Index (RAPID), resource allocation information of the Msg3, TA adjustment information, a temporary cell radio network temporary identity (TC-RNTI), and the like, which are used by the terminal device.

And step 3, the terminal device sends Msg 3.

After receiving the RAR message, the terminal device determines whether the RAR is an RAR message belonging to the terminal device, for example, the terminal device may perform a check by using a preamble index, and after determining that the RAR message belongs to the terminal device, generate Msg3 in an RRC layer, and send Msg3 to the network device, where the Msg3 may carry an identifier of the terminal device.

The Msg3 sent by the 4-step random access procedure terminal device in step 3 may include different content for different random access trigger events.

For example, for an initial access scenario, the Msg3 includes an RRC connection request message generated by an RRC layer, which may carry non-access stratum (NAS) identification information of the terminal device. Furthermore, the Msg3 may also carry, for example, a serving temporary mobile subscriber identity (S-TMSI) or a random number of the terminal device.

For another example, for the RRC connection reestablishment scenario, Msg3 includes an RRC connection reestablishment message generated by the RRC layer and does not carry any NAS messages. Furthermore, the Msg3 may also carry, for example, a C-RNTI and Protocol Control Information (PCI).

For another example, for the handover scenario, Msg3 includes an RRC handover confirm (RRC handover confirm) message generated by the RRC layer, which carries the C-RNTI of the terminal device. In addition, the Msg3 may also carry information such as Buffer Status Report (BSR).

For other triggering events, such as the scenario of up/down data arrival, Msg3 may include the C-RNTI of the terminal device.

In some cases, uplink transmissions typically use terminal device specific information. For example, data carried in an uplink shared channel (UL-SCH) is scrambled using a C-RNTI or the like. However, since the collision is not resolved at this time, only TC-RNTI can be used instead of C-RNTI when the Msg3 is scrambled.

Step 4, the network device sends Msg 4.

The network device sends Msg4 to the terminal device, and the terminal device receives Msg4 to complete contention resolution (contention resolution). In the RRC connection establishment procedure, the Msg4 may carry an RRC connection establishment message.

If the Msg3 carries the unique identifier of the terminal device, for example, C-RNTI or identification information (such as S-TMSI or a random number) from the core network, the Msg4 carries the unique identifier of the terminal device to designate the terminal device that wins the contention, and the PDCCH for scheduling Msg4 may be scrambled with the C-RNTI.

If the Msg3 does not carry the unique identifier of the terminal device, for example, during the initial access process, the Msg3 does not include the C-RNTI, the method for the terminal device to perform collision resolution may be: receiving the PDSCH in Msg4 and determining whether the contention resolution ID in the PDSCH matches a Common Control Channel (CCCH) Service Data Unit (SDU) transmitted in Msg 3. The PDCCH used for scheduling the Msg4 can be scrambled by TC-RNTI.

The terminal device that has not won the contention resolution will re-initiate random access.

In the 5G communication system, when performing random access, the terminal device may perform random access using a 2-step random access scheme in addition to the 4-step random access scheme described above. One possible approach is to send the messages Msg1 and Msg3 in a 4-step random access procedure as the first message in a 2-step random access procedure; msg2 and Msg4 in a 4-step random access procedure are sent as the second message in a 2-step random access procedure.

As shown in fig. 3, the flow of 2-step random access may include the following two steps:

in step 1, the terminal sends a first message (which may be referred to as MsgA).

The first message may include a preamble and uplink data (or payload). The uplink data may be carried in an uplink channel, and the uplink channel may be, for example, a Physical Uplink Shared Channel (PUSCH). The PUSCH may carry, for example, identification information of the terminal device, a cause of the RRC request, and the like. The first message may carry some or all of the information carried in Msg1 and Msg3 in a 4-step random access procedure.

Step 2, the network device sends a second message (which may be referred to as MsgB).

And if the network equipment successfully receives the first message sent by the terminal equipment, sending a second message to the terminal equipment. The second message may include, for example, collision resolution information, C-RNTI assignment information, TA adjustment information, and the like. This second message may carry some or all of the information carried in Msg2 and Msg4 in a 4-step random access procedure.

In the 2-step random access process, the second message carries conflict resolution information (including information related to the identifier of the terminal device sent by the terminal device in the first message), C-RNTI assignment information, TA adjustment information, and the like for a single terminal device. In addition, the second message may also carry an RRC connection setup message, etc.

Since the standardized scheme of the 2-step random access procedure is not finally determined, only fig. 3 is taken as an example for description here, and other possibilities exist for the definition of each random access message involved therein, and the present application does not limit the definition of each random access message in the 2-step random access procedure. The method described in the present application is applicable to all other 2-step random access procedures.

In the 2-step random access process, the terminal device may decode the received MsgB process and send HARQ feedback information through a PUCCH, so that the network device determines whether to perform MsgB retransmission according to the HARQ feedback information. The MsgB may carry RAR information of a plurality of terminal devices, and when the terminal devices successfully receive the MsgB, an ACK may be fed back through the PUCCH.

The network device may indicate a time slot for transmitting the DCI or an ACK/NACK time slot corresponding to the PDSCH scheduled by the DCI through an information field PDSCH-to-HARQ _ feedback timing indicator in the DCI. That is, if DCI or DCI-scheduled PDSCH is transmitted in slot n, the corresponding ACK/NACK is transmitted in slot n + k. The PDSCH-to-HARQ _ feedback timing indicator is used to indicate the value of k as described above. For DCI format 1_0, the information field length is 3 bits, and the corresponding value range may be {1, 2,3, 4, 5, 6, 7, 8 }. For DCI format 1_1, a network device first configures a set through high-layer signaling, where the set includes I elements, each element is an available value of k, and the information field length is

I is a positive integer not greater than 8.

After determining the time slot in which the PUCCH is located, resource bits of the PUCCH also need to be determinedAnd (4) placing. If the terminal device does not have the dedicated PUCCH resource configuration, for example, before the initial access phase RRC connection is established, the terminal device may obtain the PUCCH resource set according to PUCCH-ResourceCommon in the system message. As shown in the following table, PUCCH-ResourceCommon indicates one PUCCH resource set index (index) in the following table. The terminal equipment can schedule the number n of the first CCE of the PDCCH of the PDSCH according to the scheduling number_CCE,0And determining PUCCH resources in the PUCCH resource set according to the PUCCH resource indicator information indicated in the DCI. The determined PUCCH resource includes a slot, a Cyclic Shift (CS), and a Physical Resource Block (PRB) in which the PUCCH resource is located.

TABLE 1

Table 1 is an example of configuring a PUCCH provided herein, and optionally, the configuration information of configuring the PUCCH provided herein may further include time domain resource indication information, for example, indicating in which slot or slots the PUCCH is located.

If the terminal device configures a dedicated PUCCH resource set, the network device may configure one or more PUCCH resources for the terminal device through high-level signaling. The terminal device may determine a PUCCH resource in the PUCCH resource set according to a number of a first CCE of a PDCCH scheduling the PDSCH and PUCCH resource indicator information in the DCI.

At present, a PDCCH for scheduling PDSCH transmission carrying MsgB can only carry a PDSCH-to-HARQ _ feedback timing indicator and a PUCCH resource indicator of one terminal device, and the terminal device can determine one PUCCH resource by combining a PUCCH-ResourceCommon in a system message according to a unique starting CCE number of the PDCCH, and when MsgB carries RAR information of a plurality of UEs, the PUCCH indicated by the PDCCH cannot satisfy feedback requirements of the plurality of terminal devices.

Next, a method of transmitting or receiving feedback information provided in the present application is described.

As shown in fig. 4, the method 400 includes:

s410, the terminal device receives the MsgB, and the MsgB comprises at least two RARs.

Accordingly, the network device sends the MsgB.

S420, determining target order information, where the target order information is used to indicate a position of a target feedback resource in a feedback resource set.

S430, determining the target feedback resource from the feedback resource set according to the target order information.

The target order information is, for example, an RAR of the terminal device, and for convenience of distinction, the RAR of the terminal device may be referred to as a target RAR, and there is an association between the target RAR and the target feedback resource (i.e., the resource for the terminal device to transmit the feedback information of the MsgB), and the terminal device may determine the position of the target feedback resource in the feedback resource set based on the order of the target RAR among the plurality of RARs. The feedback resource set is, for example, the resource set shown in table 1.

The target order information may also be other information, for example, an Identifier (ID) of the terminal device or a C-RNTI of the terminal device, and the terminal device may determine the position of the target feedback resource in the feedback resource set according to the ID of the terminal device, or the terminal device may determine the position of the target feedback resource in the feedback resource set according to the C-RNTI of the terminal device. That is, information that can reflect the order of the terminal device among the plurality of terminal devices (terminal devices corresponding to at least two RARs in the MsgB) may each be referred to as target order information.

Before determining the target feedback resource, the terminal device may receive indication information from the network device, where the indication information is, for example, DCI carrying a PDSCH-to-HARQ _ feedback timing indicator and a PUCCH resource indicator, and the terminal device may determine the first feedback resource according to the two information fields and a number of a first CCE of the PDCCH carrying the DCI.

The first feedback resource is a feedback resource corresponding to one of a plurality of pieces of order information, for example, a plurality of RARs in the MsgB. Optionally, the first feedback resource is a feedback resource corresponding to first order information or last order information in the plurality of order information.

The terminal device may determine the target feedback resource from the feedback resource set according to an order of target order information in a plurality of order information after determining the first feedback resource, where the order of the target order information in the plurality of order information is related to the order of the target feedback resource in the feedback resource set.

For example, MsgB includes four RARs whose order is RAR1, RAR2, RAR3, and RAR4 from front to back, respectively, and the target order information may be RAR2, the order among the four RARs being the second bit; the feedback resource set comprises four feedback resources, and the four feedback resources are respectively resource 1, resource 2, resource 3 and resource 4 from front to back; if the order of the RARs 2 at the four RARs is the same as the order of the target feedback resource at the four feedback resources, the target feedback resource is resource 2; if the order of the RARs 2 at the four RARs is opposite to the order of the target feedback resource at the four feedback resources, that is, the feedback resource corresponding to the first order information is the feedback resource at the last but one, the target feedback resource is resource 3. The relation of the order of the target order information in the plurality of order information to the order of the target feedback resource in the set of feedback resources may also be other relations.

In the above example, the first feedback resource may be a resource corresponding to the first order information, for example, resource 1 or resource 4; the first feedback resource may also be a resource corresponding to order information of other orders, e.g. the first feedback resource is a resource corresponding to second order information, then the first feedback resource may be resource 2 or resource 3.

That is, the terminal device may determine the target feedback resource from the feedback resource set according to an order of the first feedback resource (equivalent to the reference resource) in the feedback resource set, an order of the target order information in the plurality of order information, and a relationship between the order of the target order information in the plurality of order information and the order of the target feedback resource in the feedback resource set.

The network device may also determine a target feedback resource from S420 and S430 before sending the MsgB.

After the terminal device and the network device determine the target feedback resource, the following steps may be performed.

S440, the terminal equipment sends the feedback information of the MsgB on the target feedback resource.

Correspondingly, the network device receives the feedback information sent by the terminal device for the MsgB on the target feedback resource.

Because the network equipment and the terminal equipment can determine the target resource of the terminal equipment based on the target sequence information, even if the DCI only indicates one feedback resource in the feedback resource set, a plurality of terminal equipment in the two-step random access process can also determine the target feedback resource of the terminal equipment, thereby solving the problem of how to indicate the uplink feedback resource for the plurality of terminal equipment in the two-step random access process. In addition, the method 400 does not need to change the content of the existing DCI, and has better compatibility.

Alternatively, the terminal device or the network device may determine the target feedback resource according to the following method.

Determining target identification information corresponding to the target feedback resource according to the sequence of the target sequence information in the sequence information and the identification information of the first feedback resource, wherein the target identification information has an association relation with the identification information of the first feedback resource;

and determining target feedback resources from a feedback resource set according to the target identification information.

The identification information is, for example, a PUCCH Resource Indicator (PRI).

As shown in fig. 5, the MsgB includes RARs of 8 UEs, the RARs of the 8 UEs are, in order from front to back, RAR1(UE1), RAR2(UE2), RAR3(UE3), RAR4(UE4), RAR5(UE5), RAR6(UE6), RAR7(UE7), and RAR8(UE8), the first feedback resource (PUCCH1) is a feedback resource corresponding to the first RAR, and the PRI indicating the first feedback resource in the DCI is the first PRI (000).

After receiving the DCI, the UE1 determines the target PRI to be the first PRI according to the sequence of the RAR1, or determines the target PRI to be the PRI (000) obtained after the first PRI is processed by a predefined rule according to the sequence of the RAR1, and then determines the PUCCH1 to be the target feedback resource based on the PRI (000).

After receiving the DCI, the UE2 determines the target PRI for the second bit according to the order of the RAR2 as the PRI (100) obtained after the first PRI is processed by the predefined rule, and then determines the PUCCH5 as the target feedback resource based on the PRI (100).

Other UEs may also determine their respective PRIs and finally determine their own target feedback resources through a similar method.

Optionally, in order to minimize interference between PUCCH resources of different UEs, the predefined rule may enable PUCCH resources allocated by UEs in adjacent orders to satisfy the following characteristics: the time domain interval is as large as possible, and/or the frequency domain interval is as large as possible, and/or the cyclic shift interval is as large as possible. By the predefined rule, interference among PUCCHs of different UEs can be reduced, the receiving performance of the PUCCHs is improved, and invalid retransmission of the MsgB is reduced.

The identification information may also be a first Control Channel Element (CCE) number of the PDCCH.

As shown in fig. 6, the MsgB includes RARs of 8 UEs, the RARs of the 8 UEs are sequentially RAR1(UE1), RAR2(UE2), RAR3(UE3), RAR4(UE4), RAR5(UE5), RAR6(UE6), RAR7(UE7), and RAR8(UE8) from front to back, the first feedback resource (PUCCH1) is a feedback resource corresponding to the first RAR, and the first CCE number of the PDCCH is CCE (000).

After receiving the DCI carried by the PDCCH, the UE1 determines that the target CCE number is CCE (000) for the first bit according to the order of the RAR1, or determines the CCE (000) obtained after the target CCE number is CCE (000) and performing predefined rule processing for the first bit according to the order of the RAR1, and then determines the PUCCH1 as the target feedback resource based on the CCE (000).

After receiving the DCI carried by the PDCCH, the UE2 determines a CCE (100) obtained by performing predefined rule processing on a target CCE number CCE (000) for the second bit according to the order of the RAR2, and then determines the PUCCH5 as a target feedback resource based on the CCE (100).

Other UEs may also determine their respective target CCE numbers by a similar method, and finally determine their own target feedback resources.

Having described in detail several examples provided herein for determining a target feedback resource from a set of feedback resources, the following describes a set of feedback resources provided herein.

In this application, the configuration information (e.g., pucch-ResourceCommon) may configure a feedback resource set in 1 time domain resource (e.g., 1 timeslot), and may also configure a feedback resource set in multiple timing resources. Optionally, the configuration information may contain an information field indicating time domain resources, which may indicate the number and/or location of time domain resources.

For example, the UE may determine one available PUCCH resource set (i.e., a feedback resource set) according to the PUCCH-resource common configuration, and all possible PUCCH resource indicator values, and the number of all possible first CCEs in the core set of the PDCCH. Different PUCCH resources in the available PUCCH resource sets are different in at least one dimension of time domain, frequency shift, and cyclic shift to maintain orthogonality with each other. The PUCCH-ResourceCommon configuration includes slot information of the PUCCH, for example, includes two different slots. In addition to the newly introduced timeslot information, the pucch-ResourceCommon may multiplex the configuration information of 4-step random access, that is, the prior art of NR Rel-15, and may also newly define the configuration information for 2-step random access.

In this application, "each other" means between any two, for example, the time domain resources of the M feedback resources are different from each other, which means that the time domain resources of any two of the M feedback resources are different.

As shown in fig. 7, the available PUCCH resource set determined by the UE includes PUCCH resources with different at least one dimension of time domain, frequency shift, and cyclic shift. Within one slot, the available PUCCH resource set includes 16 PUCCH resources of different PRBs and CSs. For the two-slot case, the available PUCCH resource set includes a total of 32 PUCCH resources of different slots, PRBs, and CSs. They are within the initial Uplink (UL) partial Bandwidth (BWP).

And determining PUCCH resources of the first UE in the UEs corresponding to the RAR loaded in the MsgB through a PDSCH-to-HARQ _ feedback timing indicator and a PUCCH resource indicator in the DCI and the number of the first CCE of the PDCCH. And determining resource positions of respective PUCCH resources in the available PUCCH resource set according to a certain rule, such as the position of RAR corresponding to the UE in MsgB, on the basis of the PUCCH of the first UE by the PUCCHs of the other UEs.

Optionally, if the available PUCCH resource set includes more than one slot, the PUCCH resources are mapped to the UE according to the sequence of time domain (slot), frequency domain (PRB), and Cyclic Shift (CS).

Optionally, if a slot is included in the available PUCCH resource set, the PUCCH resources are mapped to the UE according to the order of frequency domain (PRB) and Cyclic Shift (CS).

Optionally, for frequency domain mapping, the PRBs in which the PUCCH resources are located are mapped in order of decreasing intervals. For example, for PRB numbers of 0,1,2, and 3 where PUCCH resources are located, the mapping order is 0,3,1, and 2.

Optionally, for mapping of cyclic shift, the mapping is performed in order from large to small intervals of the CS corresponding to the PUCCH resources. For example, for CS ═ {0,3,6,9}, the mapping order is 0,6,3, 9.

Taking two slots as an example, as shown in fig. 7, if the PUCCH resource on slot n indicated in DCI is a PUCCH resource with CS being 0 on PRB 0, the PUCCH of the UE corresponding to the RAR carried in MSG B is mapped in the following order:

1 st UE: the PUCCH resource on the time slot n is the PUCCH resource of which CS is 0 on PRB 0;

the 2 nd UE: the PUCCH resource on the time slot n +1 is the PUCCH resource of which CS is 0 on PRB 0;

the 3 rd UE: the PUCCH resource on the time slot n is the PUCCH resource of CS ═ 0 on PRB 3;

the 4 th UE: the PUCCH resource on the time slot n +1 is the PUCCH resource of CS ═ 0 on PRB 3;

the 5th UE: the PUCCH resource on the time slot n is the PUCCH resource of CS ═ 0 on PRB 1;

the 6 th UE: the PUCCH resource on the time slot n +1 is the PUCCH resource of which CS is 0 on PRB 1;

the 7 th UE: the PUCCH resource on the time slot n is the PUCCH resource of CS ═ 0 on PRB 2;

the 8 th UE: the PUCCH resource on the time slot n +1 is the PUCCH resource of CS ═ 0 on PRB 2;

the 9 th UE: the PUCCH resource on the time slot n is the PUCCH resource of CS ═ 6 on PRB 0;

……

and so on until all the UEs are mapped. The UE is mapped on the PUCCH resource, which may be understood as the UE determining the PUCCH resource, or the RAR (or other order information) is mapped on the PUCCH resource, or the UE determining a mapping relationship or a corresponding relationship between the order information and the feedback resource.

The above examples should not be understood as limiting the present application, for example, the present application does not limit the PRB and CS mapped by the 2 nd UE; the time domain resources of the UE3 and the time domain resources of the UE1 are the same, and when the UE3 is mapped, the frequency domain resources and the CS of the PUCCH resources mapped by the UE3 may be different from those of the UE1, and are not limited to PRB 3 and CS 0; similarly, the time-frequency resources of UE9 and UE1 are the same, and the CS of the PUCCH resource mapped by UE9 may be different from the CS of UE1, which is not limited to be CS 6.

According to the scheme, PUCCH resources of all the UEs are implicitly indicated according to a predefined rule, and the signaling overhead of DCI or MsgB can be reduced. The time domain (time slot), the frequency domain (PRB) and the Cyclic Shift (CS) are mapped in sequence, so that the interference among the PUCCHs of different UEs can be reduced as much as possible, the receiving performance of the PUCCHs is improved, and the invalid retransmission of the MsgB is reduced.

The mapping relationship between the UE and the feedback resource can also be shown in fig. 8.

In fig. 8, the available PUCCH resource set determined by the UE includes PUCCH resources with different at least one dimension of time domain, frequency shift, and cyclic shift. Within one slot, the available PUCCH resource set includes 16 PUCCH resources of different PRBs and CSs. For the two-slot case, the available PUCCH resource set includes a total of 32 PUCCH resources of different slots, PRBs, and CSs. They are within the initial UL BWP.

Optionally, the feedback resource configured by the network device is a feedback resource in the time slot n, and the feedback in the time slot n +1 is determined by the terminal device itself. Or, the network device may also configure feedback resources in multiple time slots, and when the feedback resources configured by the network device are not enough to be allocated to the UE corresponding to all RARs in the MsgB, the UE may determine the feedback resources based on the feedback resources configured by the network device itself, that is, in this application, the feedback resources in the feedback resource set determined by the terminal device may all be configured by the network device, or may be partially configured by the network device.

As shown in fig. 8, a PDSCH-to-HARQ _ feedback timing indicator in DCI indicates that a PUCCH resource set is located in slot n, including 16 PUCCH resources. The RARs included in the MsgB correspond to 32 UEs, and the order of the 32 UEs is ranked from UE1 to UE32 in turn, where UE1-UE16 are mapped on 16 PUCCH resources of slot n according to a rule. Starting from UE 17, the PUCCH resource sets mapped on slot n +1 follow the same rule.

Based on the scheme, on the premise of not changing the indication information in the existing DCI, the UE can flexibly expand PUCCH resources according to the number of the UEs corresponding to the RAR carried by the MsgB.
