Description

Transmission method, device, terminal and network side equipment of physical uplink control channel

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, a terminal, and a network side device for transmitting a physical uplink control channel.

Background

With the development of mobile communication service requirements, several organizations such as the international telecommunication union ITU have started to research New wireless communication systems (i.e. 5G NR, 5Generation New RAT, 5G New air interface) for future mobile communication systems. Currently, 5 PUCCH (Physical Uplink Control Channel) formats (formats) are defined in 5G NR, and as shown in table 1, PUCCH formats 0 and 2 may be referred to as a short PUCCH format because the time domain occupies only 1 to 2 symbols, and PUCCH format 1/3/4 may be referred to as a long PUCCH format because the time domain occupies 4 to 14 symbols.

Table 1 PUCCH format as defined in NR system

In this case, the OCC is an Orthogonal Code (Orthogonal Code), and the length of OCC represents the length of the Orthogonal Code.

The symbol is an OFDM (Orthogonal Frequency Division Multiplexing) symbol or an SC-FDMA (Single-carrier Frequency-Division Multiple Access) symbol or a DFT-s-OFDM (Discrete Fourier Transform-Spread OFDM, Orthogonal Frequency Division Multiple Access) symbol.

In consideration of scheduling flexibility and transmission requirements of different Uplink Control Information (UCI), a plurality of PUCCHs may be supported in the NR system to transmit Time Division Multiplexing (TDM) in the same slot. TDM means that a plurality of PUCCHs occupy different symbol transmissions in the same slot and do not overlap with each other in the time domain. However, it is considered that the maximum number of symbols occupied by the long PUCCH format may be 14 symbols, and only 14 symbols are included in 1 slot corresponding to a baseband parameter (numerology) of a 15kHz subcarrier spacing, so that only at most 2 PUCCHs are currently supported in the NR system to be transmitted in the same slot in a TDM manner, and the 2 PUCCHs include at least one short PUCCH format, that is, two short PUCCH formats, one short PUCCH format and one long PUCCH format, but two long PUCCH formats are not supported for transmission in the same slot in a TDM manner.

The UCI at least includes HARQ-ACK (Hybrid Automatic Repeat Request-ACK), CSI (Channel State Information), and SR (Scheduling Request). Wherein HARQ-ACK may be a time domain position (including a slot and a symbol position within the slot) of a transmission determined according to a dynamic feedback timing or a fixed feedback timing. The dynamic feedback timing is an interval between an indication field indicating an end position of Downlink transmission and a time slot transmitting HARQ-ACK feedback Information of the Downlink transmission in DCI for scheduling Downlink transmission, and a specific symbol position in the time slot is determined from a plurality of PUCCH resources pre-configured by a higher layer signaling according to the indication field in DCI (Downlink Control Information). The fixed feedback timing is a value of an interval from an end position of a downlink transmission to a time slot for transmitting HARQ-ACK feedback information of the downlink transmission, which is directly configured by a higher layer signaling. Whether the dynamic feedback time sequence or the fixed feedback time sequence is based on the end position of the downlink transmission, the time slot of the HARQ-ACK feedback is determined, and when the downlink transmission is dynamically scheduled, the time slot of the HARQ-ACK feedback is dynamically changed along with the time slot. The transmission resources of the CSI and the SR on the PUCCH are preconfigured by higher layer signaling, and are periodically transmitted according to the transmission opportunity determined by the preconfigured period and offset, so the time domain position of transmission thereof is relatively fixed. A transmission period of one CSI report is not shorter than 1 slot, but a plurality of different CSI reports may exist in one slot. The shortest transmission cycle of one SR configuration may be 2 symbols, so that multiple SR transmission cycles corresponding to the same SR configuration may exist in one timeslot, and multiple SR configurations may also be configured, and a transmission cycle and an offset of each SR configuration are configured independently, so that a TDM transmission opportunity of multiple SR configurations may exist in one timeslot. Both of the above cases result in more than 2 PUCCH for TDM transmission in one slot.

In summary, when the 5G NR system specifies that only a limited number of PUCCH transmissions with non-overlapping time domain resources in one slot are supported, there is no explicit method to select which PUCCH to transmit and discard which PUCCH to not transmit.

Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, an embodiment of the present invention further provides a transmission method for a physical uplink control channel PUCCH, which is applied to a terminal, and includes:

step 11, in a time unit, selecting no more than M PUCCHs to transmit in the time unit according to a preset rule; the unselected PUCCHs are discarded, i.e., they are not transmitted in the time unit.

Wherein time domain resources of the selected PUCCHs in the time unit are not overlapped with each other; m is an integer greater than or equal to 1.

In a preferred embodiment of the present invention, the time unit is: a slot, or a plurality of slots, or a subframe, or a plurality of subframes, or a predetermined length of time.

Preferably, the preset rule comprises at least one of the following rules:

the second rule is as follows: selecting a PUCCH bearing UCI with high UCI type priority according to the UCI type priority of uplink control information UCI borne by the PUCCH; namely, the UCI type priority is selected from high to low, wherein the UCI type priority is in the following order:

the priority of hybrid automatic repeat request acknowledgement HARQ-ACK is higher than that of a scheduling request SR, and the priority of the SR is higher than that of channel state information CSI; alternatively, the priority of the HARQ-ACK and/or SR is higher than the priority of the CSI.

In other words, the priority of the PUCCH carrying HARQ-ACK is higher than that of the PUCCH carrying SR, and the priority of the PUCCH carrying SR is higher than that of the PUCCH carrying CSI; or the priority of the PUCCH carrying the HARQ-ACK and/or SR is higher than that of the PUCCH carrying the CSI.

A third rule: selecting a PUCCH corresponding to the transmission length with high priority according to the transmission length priority of the PUCCH, or selecting a PUCCH corresponding to the format with high priority according to the format priority of the PUCCH; namely, the transmission length priority or the format priority of the PUCCH is selected from high to low, wherein the transmission length priority of the PUCCH is in the following order: the transmission length priority of the short PUCCH is higher than that of the long PUCCH; and/or the format priority of the PUCCH is in the following sequence: the format priority of PUCCH format 0 or 2 is higher than the format priority of PUCCH format 1 or 3 or 4.

Wherein the predetermined second priority comprises:

for a plurality of PUCCHs bearing HARQ-ACK, selecting the PUCCH bearing the HARQ-ACK corresponding to the service type with high priority according to the service type priority corresponding to the HARQ-ACK borne by the PUCCH; for example, the priority of the enhanced mobile bandwidth URLLC service is higher than that of the eMBB service in the ultra-reliable low-latency communication, the dynamic service > semi-persistent scheduling SPS service, and the like

For a plurality of PUCCHs bearing different SR configurations, selecting the PUCCH bearing the SR configuration with a smaller number or selecting the PUCCH with the SR configuration with a larger number according to the number sequence of the SR configuration borne by the PUCCH; in this case, whether the PUCCH with the SR configuration with the smaller number is selected or the PUCCH with the SR configuration with the larger number is selected needs to be agreed in advance by the terminal and the network side device to ensure consistent selection.

For a plurality of PUCCHs carrying CSI, selecting a PUCCH carrying a CSI report with high priority according to the priority of the CSI report carried by the PUCCH, wherein the priority of the CSI report is determined according to a preset rule. For example, the priority of the CSI report is: carrier priority (such as the sequence of downlink carrier numbers corresponding to the CSI from small to large or the sequence of downlink carrier numbers from large to small), CSI report type priority (such as the priority of AP-CSI is greater than that of SP-CSI, and the priority of SP-CSI is greater than that of P-CSI), CSI report content priority (such as the priority containing L1-RSRP is greater than that not containing L1-RSRP), and CSI report number priority (the sequence of CSI report numbers from small to large or the sequence of CSI report numbers from large to small). The priorities of the above exemplified CSI reports may be used alone or in combination.

Further, in the above embodiment of the present invention, when one PUCCH simultaneously carries multiple types of UCI, the second rule is:

and selecting the PUCCH according to the highest UCI type priority in the UCIs of the plurality of types carried by the PUCCH. That is, when a plurality of PUCCHs carrying various types of UCI are selected, the highest UCI type priority of UCI carried by each PUCCH is compared, so that a PUCCH carrying UCI of higher UCI type priority is selected.

For example, PUCCH 1 carries HARQ-ACK and CSI, PUCCH2 carries CSI and SR, and when one PUCCH is selected according to the second rule, PUCCH 1 carrying HARQ-ACK is selected according to UCI type priority of HARQ-ACK carried by PUCCH 1 and UCI type priority of SR carried by PUCCH 2. Wherein, the priority of HARQ-ACK is higher than that of SR, and the priority of SR is higher than that of CSI.

or, selecting a PUCCH carrying UCI with a high UCI type priority according to the UCI type priority, further selecting a PUCCH with a high priority according to a predetermined second priority for a plurality of PUCCHs carrying UCI of the same type or a plurality of PUCCHs carrying UCI with the same UCI type priority, and further selecting a PUCCH corresponding to a transmission length of the high priority or a PUCCH corresponding to a format of the PUCCH according to a transmission length priority of the PUCCH for a plurality of PUCCHs corresponding to the same second priority;

Preferably, step 11 in the above embodiment of the present invention includes:

Preferably, in the above embodiment of the present invention, when the PUCCH selected according to the preset rule has reached a first type of PUCCH, if there is still a first type of PUCCH unselected in the time unit, the unselected first type of PUCCH is discarded; it should be noted that, if the number of the selected PUCCHs at this time has not reached the predetermined number, the terminal may continue to select the PUCCH, but the selected PUCCH cannot be the first-type PUCCH. That is, when the selected first PUCCH reaches the upper limit, if there are subsequent first PUCCH as candidate PUCCH, these PUCCHs are not selected; for example, if a first PUCCH is specified to be long PUCCH, and M is 2 and two long PUCCHs cannot be transmitted in one slot, that is, a is 1, the terminal may further select one PUCCH again if the first selected PUCCH is short PUCCH, because no matter whether the next selected PUCCH is short or long, the requirement is satisfied (that is, two long PUCCH transmissions do not occur), so M is always 2 PUCCH transmissions may be selected, but if the first selected PUCCH is long PUCCH, the upper limit number a of long PUCCH is reached, and these PUCCHs will not be selected if long PUCCH exists in subsequent candidate PUCCHs; in this case, one implementation is to continue to select according to the PUCCH selection rule, and if the selected second PUCCH is long PUCCH, discard this PUCCH, and end the selection, that is, only the first selected long PUCCH is finally transmitted; another implementation manner is to remove the long PUCCH in the subsequent PUCCH to be selected, that is, when selecting the second PUCCH, the long PUCCH is not taken as the candidate PUCCH, and only the short PUCCH is considered, one short PUCCH is selected according to the PUCCH selection rule, and the second PUCCH is taken as the second PUCCH, and finally M ═ 2 PUCCHs are selected.

Wherein a is a maximum number of the first PUCCH supported for transmission in a predefined time unit, the first PUCCH is a predetermined PUCCH format or a PUCCH with a specific transmission length, for example, the first PUCCH is a long PUCCH or a PUCCH with a transmission length not less than B symbols, and B is a predetermined positive integer, for example, B is 4; a is a number not exceeding M.

Or when each PUCCH selected according to the preset rule is a second-type PUCCH, selecting M PUCCHs; the second type of PUCCH is a predetermined PUCCH format or a PUCCH with a specific transmission length, for example, the first type of PUCCH is a short PUCCH or a PUCCH with a transmission length not greater than B symbols, and B is a predetermined positive integer, such as B ═ 4 or 2. That is, if each selected PUCCH is a second type PUCCH, M PUCCHs may be selected to be transmitted in one time unit; for example, if the second PUCCH is short PUCCH and M is 2 and two long PUCCHs cannot be transmitted in one slot, the terminal may further select one PUCCH if the first selected PUCCH is short PUCCH, and since the next selected PUCCH is short PUCCH or long PUCCH, which is satisfactory (i.e., two long PUCCH transmissions do not occur), M may always be selected for 2 PUCCH transmission.

It should be noted that, in the above embodiments of the present invention, if a terminal configures multiple PUCCH carrier groups, or configures a primary carrier group and a secondary carrier group, the transmission method of the PUCCH according to the above physical uplink control channel needs to be separately executed in each carrier group. For example, a terminal configures a carrier group 1 and a carrier group 2, and the terminal needs to select no more than M PUCCHs in the carrier group 1 and the carrier group 2 according to a preset rule to transmit in one time unit.

In summary, in the transmission method of the PUCCH provided in the above embodiments of the present invention, the terminal selects, according to the preset rule, no more than M PUCCHs to be transmitted in the same time unit, and sends the determined no more than M PUCCHs, and the network side device receives the determined no more than M PUCCHs, so that understanding of the PUCCH to be transmitted by the terminal and the network side device is avoided being inconsistent while limiting the output number of the PUCCHs in the same time unit to reduce system overhead, thereby ensuring normal operation of the system.

As shown in fig. 2, an embodiment of the present invention further provides a transmission method for a physical uplink control channel PUCCH, which is applied to a network side device, and includes:

Preferably, the preset rule comprises at least one of the following rules:

a ninth combination rule (equivalent to a combination of the second rule, the third rule, and the fourth rule): selecting a PUCCH carrying UCI with high UCI type priority according to UCI type priority, further selecting a PUCCH corresponding to the transmission length of the high priority or selecting a PUCCH corresponding to the format of the high priority according to the transmission length priority of the PUCCH or selecting a PUCCH corresponding to the format of the PUCCH, and further selecting a PUCCH with high priority according to a predetermined second priority for a plurality of PUCCHs corresponding to the same transmission length priority or format priority;

Preferably, step 21 in the above embodiment of the present invention includes:

Preferably, in the above embodiment of the present invention,

when the PUCCHs selected according to the preset rule reach A first-class PUCCHs, if the first-class PUCCHs are not selected in the time unit, discarding the unselected first-class PUCCHs; it should be noted that, if the number of the selected PUCCHs at this time has not reached the predetermined number, the terminal may continue to select the PUCCH, but the selected PUCCH cannot be the first-type PUCCH. That is, when the selected first PUCCH reaches the upper limit, if there are subsequent first PUCCH as candidate PUCCH, these PUCCHs are not selected; for example, if a first PUCCH is specified to be long PUCCH, and M is 2 and two long PUCCHs cannot be transmitted in one slot, that is, a is 1, the terminal may further select one PUCCH again if the first selected PUCCH is short PUCCH, because no matter whether the next selected PUCCH is short or long, the requirement is satisfied (that is, two long PUCCH transmissions do not occur), so M is always 2 PUCCH transmissions may be selected, but if the first selected PUCCH is long PUCCH, the upper limit number a of long PUCCH is reached, and these PUCCHs will not be selected if long PUCCH exists in subsequent candidate PUCCHs; in this case, one implementation is to continue to select according to the PUCCH selection rule, and if the selected second PUCCH is long PUCCH, discard this PUCCH, and end the selection, that is, only the first selected long PUCCH is finally transmitted; another implementation manner is to remove the long PUCCH in the subsequent PUCCH to be selected, that is, when selecting the second PUCCH, the long PUCCH is not taken as the candidate PUCCH, and only the short PUCCH is considered, one short PUCCH is selected according to the PUCCH selection rule, and the second PUCCH is taken as the second PUCCH, and finally M ═ 2 PUCCHs are selected.

In summary, in the PUCCH transmission method provided in the foregoing embodiment of the present invention, the network side device selects, according to a preset rule, no more than M PUCCHs to be transmitted in the same time unit, and receives the determined no more than M PUCCHs, so that understanding of the PUCCH to be transmitted by the terminal and the network side device is avoided being inconsistent while limiting the output number of the PUCCHs in the same time unit to reduce system overhead, thereby ensuring normal operation of the system.
