Description

Physical uplink control channel transmission method, device, equipment and medium

Technical Field

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

Background

The main scenarios of the current mobile communication system include: enhanced mobile broadband (Enhanced Mobile Broadband, emmbb), ultra Reliable low latency communication (Ultra Reliable & Low Latency Communication, URLLC), and mass machine type communication (massive Machine Type of Communication, mctc).

It is possible for some terminal devices to support different services, e.g. the terminal device supports both URLLC and eMBB services. For downlink data transmission of different services, the terminal device may simultaneously construct a plurality of different hybrid automatic repeat request acknowledgement (Hybrid Automatic Repeat Request ACK, HARQ-ACK) codebooks (codebooks), different HARQ-ACKs may correspond to different time granularity, and may be transmitted on different physical uplink control channels (Physical Uplink Control Channel, PUCCH). For example, the time granularity corresponding to the ebb HARQ-ACK is at a slot (slot) level, and the time granularity corresponding to the URLLC HARQ-ACK is at a sub-slot (sub-slot) level, so that the time domains of the transmission resources overlap.

When the transmission resource time domains overlap, the single carrier characteristics of the terminal device may be destroyed, and channel estimation performance may be affected.

Detailed Description

The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Fig. 1 shows a schematic view of a scenario provided by an embodiment of the present invention. In this scenario, PUCCH 0 carrying the first HARQ-ACK of the first time granularity overlaps n PUCCHs on the time domain resource, and n PUCCHs do not overlap on the time domain resource, n PUCCHs carrying the second HARQ-ACK of the second time granularity, n PUCCHs being PUCCH 1, PUCCH 2, PUCCH3, PUCCH 4, … …, PUCCH n, respectively. At this time, the single carrier characteristic of the terminal device is destroyed, and the channel estimation performance is affected.

In order to solve the problems in the prior art, the embodiment of the invention provides a PUCCH transmission method, a device, equipment and a medium. The following first describes in detail a PUCCH transmission method provided in an embodiment of the present invention.

Fig. 2 shows a flowchart of a PUCCH transmission method applied to a terminal device according to an embodiment of the present invention. The PUCCH transmission method applied to the terminal device may include:

s201: whether the first PUCCH and the second PUCCH overlap on the time domain resource is determined, and if the first PUCCH and the second PUCCH overlap on the time domain resource, S202 is executed.

Wherein, the first PUCCH carries a first HARQ-ACK at a first time granularity; the second PUCCH carries a second HARQ-ACK at a second time granularity. The first temporal granularity is greater than the second temporal granularity. Time granularity is also commonly referred to as time units. The first time granularity and the second time granularity may be predefined by the network side device through signaling configuration or indication or a protocol, and the embodiment of the present invention is not limited.

S202: according to a predefined transmission rule, a PUCCH carrying HARQ-ACK is transmitted.

In one embodiment of the present invention, in the first case, the first PUCCH may overlap with one second PUCCH on time domain resources. In the second case, the first PUCCH may overlap with at least two second PUCCHs on time domain resources, and the at least two second PUCCHs do not overlap on time domain resources.

Based on this, the network side device may transmit a first physical downlink control channel (Physical downlink control channel, PDCCH) or a first physical downlink shared channel (Physical downlink shared channel, PDSCH) to the terminal device, and at least one second PDCCH or second PDSCH to the terminal device; wherein, the first PDCCH or the first PDSCH corresponds to a first HARQ-ACK with first time granularity; at least one second PDCCH or second PDSCH is respectively in one-to-one correspondence with at least one second HARQ-ACK of a second time granularity; the first temporal granularity is greater than the second temporal granularity; the terminal equipment feeds back the PUCCH carrying the HARQ-ACK. The network side equipment receives the PUCCH carrying the HARQ-ACK.

The network side device provided by the embodiment of the invention can be a base station, which can be a commonly used base station, an evolved node B (evolved node base station, eNB), network side devices in a 5G system (such as a next generation base station (next generation node base station, gNB) or a transmitting and receiving point (transmission and reception point, TRP)) or a cell (cell) or the like, or network side devices in a subsequent evolved communication system. However, the above words do not limit the scope of the present invention. In some embodiments, the terminal device may be a mobile phone, a tablet computer, a smart watch, a smart home appliance, etc., which is not limited in this embodiment of the present invention.

Illustratively, assume that the first temporal granularity is at a slot level and the second temporal granularity is at a sub-slot level. One slot may contain multiple sub-slots, the size of which may be a radio resource control (Radio Resource Control, RRC) configuration or downlink control information (Downlink Control Information, DCI) indication. The first time granularity corresponding to the slot level is greater than the second time granularity corresponding to the sub-slot level.

In an embodiment of the present invention, the terminal device may determine whether the first PUCCH and the second PUCCH overlap on the time domain resource according to the second time granularity (i.e. the time granularity corresponding to the sub-slot level). That is, whether the time domain resources overlap or not can be judged according to the time granularity of the sub-slot level.

When the terminal equipment judges that the first PUCCH and the second PUCCH overlap on the time domain resource according to the time granularity corresponding to the sub-slot level, the terminal equipment can transmit the PUCCH carrying the HARQ-ACK according to a predefined transmission rule.

The following description will be made for the two cases described above, respectively.

For the case where the first PUCCH overlaps one second PUCCH on a time domain resource.

In one embodiment of the present invention, the terminal device may cancel transmission of the first PUCCH and transmit the second PUCCH. I.e. the terminal device does not transmit the first PUCCH but only the second PUCCH.

According to the embodiment of the invention, when the PUCCH of the HARQ-ACK with long bearing time granularity and the PUCCH of the HARQ-ACK with short bearing time granularity are overlapped on the time domain resource, only the PUCCH of the HARQ-ACK with short bearing time granularity is transmitted, so that the single carrier characteristic of the terminal equipment can be ensured, and the channel estimation performance is improved.

In one embodiment of the present invention, the terminal device may cancel transmission of the time domain resource overlapping portion in the first PUCCH and transmit the second PUCCH; after the second PUCCH transmission is completed, the remaining portion after the time domain resource overlapping portion in the first PUCCH is transmitted.

According to the embodiment of the invention, when the PUCCH of the HARQ-ACK with long bearing time granularity and the PUCCH of the HARQ-ACK with short bearing time granularity are overlapped on the time domain resource, the PUCCH of the HARQ-ACK with short bearing time granularity is transmitted, and after the transmission of the PUCCH of the HARQ-ACK with short bearing time granularity is completed, the rest part after the time domain resource overlapping part in the PUCCH of the HARQ-ACK with long bearing time granularity is transmitted, the single carrier characteristic of the terminal equipment can be ensured, and the channel estimation performance is improved.

In one embodiment of the present invention, the terminal device may cancel transmission of the first PUCCH, multiplex the first HARQ-ACK with the second HARQ-ACK on one PUCCH, for example, multiplex on the second PUCCH, or multiplex on another PUCCH other than the second PUCCH, wherein the other PUCCH may be determined according to a predetermined rule.

According to the embodiment of the invention, when the PUCCH carrying the HARQ-ACK with long time granularity and the PUCCH carrying the HARQ-ACK with short time granularity are overlapped on the time domain resource, the HARQ-ACK with long time granularity and the HARQ-ACK with short time granularity are multiplexed on one PUCCH for transmission, so that the single carrier characteristic of the terminal equipment can be ensured, and the channel estimation performance is improved.

In one embodiment of the present invention, the terminal device may cancel the PUCCH carrying the HARQ-ACK with the lower priority from among the first HARQ-ACK and the second HARQ-ACK from the transmission, and the PUCCH carrying the HARQ-ACK with the higher priority from among the first HARQ-ACK and the second HARQ-ACK from the transmission.

For example, assuming that the priority of the first HARQ-ACK is higher than the priority of the second HARQ-ACK, the terminal device cancels transmission of the second PUCCH and transmits the first PUCCH.

Further exemplary, assuming that the priority of the first HARQ-ACK is lower than the priority of the second HARQ-ACK, the terminal device cancels transmission of the first PUCCH and transmits the second PUCCH.

According to the embodiment of the invention, when the PUCCH of the HARQ-ACK with long bearing time granularity and the PUCCH of the HARQ-ACK with short bearing time granularity are overlapped on the time domain resource, the PUCCH of the HARQ-ACK with low transmission priority is canceled, and the PUCCH of the HARQ-ACK with high bearing priority is transmitted, so that the single carrier characteristic of the terminal equipment can be ensured, and the channel estimation performance is improved.

In one embodiment of the present invention, the terminal device may cancel the time domain resource overlapping portion in the PUCCH carrying the HARQ-ACK with low priority from the first HARQ-ACK and the second HARQ-ACK, and transmit the PUCCH carrying the HARQ-ACK with high priority from the first HARQ-ACK and the second HARQ-ACK; after the completion of the PUCCH transmission carrying the high priority HARQ-ACK of the first and second HARQ-ACKs, transmitting the remaining portion after the time domain resource overlapping portion in the low priority PUCCH of the first and second HARQ-ACKs.

For example, assuming that the priority of the first HARQ-ACK is higher than that of the second HARQ-ACK, the terminal device cancels transmission of the time domain resource overlapping portion in the second PUCCH, and transmits the first PUCCH; after the first PUCCH transmission is completed, the remaining portion after the time domain resource overlapping portion in the second PUCCH is transmitted.

For another example, assuming that the priority of the first HARQ-ACK is lower than the priority of the second HARQ-ACK, the terminal device cancels transmission of the time domain resource overlapping portion in the first PUCCH and transmits the second PUCCH; after the second PUCCH transmission is completed, the remaining portion after the time domain resource overlapping portion in the first PUCCH is transmitted.

In one embodiment of the present invention, the terminal device may cancel the PUCCH transmitting the HARQ-ACK with the low priority from among the first HARQ-ACK and the second HARQ-ACK, and multiplex the HARQ-ACK with the low priority from among the first HARQ-ACK and the second HARQ-ACK with the high priority from among the first HARQ-ACK and the second HARQ-ACK for transmission on one PUCCH.

For example, assuming that the priority of the first HARQ-ACK is higher than the priority of the second HARQ-ACK, the terminal device cancels transmission of the second PUCCH and multiplexes the first HARQ-ACK and the second HARQ-ACK for transmission on one PUCCH. For example, multiplexing is transmitted on the first PUCCH or multiplexing is transmitted on one other PUCCH than the first PUCCH, wherein the other PUCCH may be determined according to a predetermined rule.

For example, assuming that the priority of the first HARQ-ACK is lower than the priority of the second HARQ-ACK, the terminal device cancels transmission of the first PUCCH and multiplexes the second HARQ-ACK with the first HARQ-ACK for transmission on one PUCCH. For example, multiplexing is transmitted on the second PUCCH or multiplexing is transmitted on one other PUCCH than the second PUCCH, wherein the other PUCCH may be determined according to a predetermined rule.

For the case where the first PUCCH overlaps with the at least two second PUCCHs on time domain resources and the at least two second PUCCHs do not overlap on time domain resources.

In one case, the first PUCCH overlaps with the two second PUCCHs on time domain resources, and the two second PUCCHs do not overlap on time domain resources. In another case, the first PUCCH overlaps n second PUCCHs on time domain resources, and the n second PUCCHs do not overlap on time domain resources, where n is greater than 2.

For the case where the first PUCCH overlaps with the two second PUCCHs on time domain resources and the two second PUCCHs do not overlap on time domain resources, it is assumed that the two second PUCCHs are PUCCH 1 and PUCCH 2, respectively.

In one embodiment of the present invention, the terminal device may cancel transmission of the first PUCCH, and transmit PUCCH 1 and PUCCH 2.

In one embodiment of the present invention, the terminal device may cancel transmission of the time domain resource overlapping portion in the first PUCCH and transmit PUCCH 1 and PUCCH 2; after the PUCCH 1 and PUCCH 2 transmission is completed, the remaining part after the time domain resource overlapping part in the first PUCCH is transmitted.

In one embodiment of the present invention, the terminal device may cancel transmission of the first PUCCH, multiplex the first HARQ-ACK with the second HARQ-ACK on one PUCCH, for example, multiplex on PUCCH 1, multiplex on PUCCH 2, or multiplex on another PUCCH other than PUCCH 1 and PUCCH 2, wherein the other PUCCH may be determined according to a predetermined rule.

In one embodiment of the present invention, the terminal device may multiplex the first HARQ-ACK with a second HARQ-ACK carried by one PUCCH having the earliest starting symbol in PUCCH 1 and PUCCH 2 for transmission on one PUCCH; the terminal equipment can also multiplex the first HARQ-ACK with a second HARQ-ACK carried by one PUCCH with the latest starting symbol or ending symbol in the PUCCH 1 and the PUCCH 2 to be transmitted on one PUCCH; the terminal equipment can also multiplex the first HARQ-ACK with a second HARQ-ACK carried by one PUCCH with the lowest code rate in PUCCH 1 and PUCCH 2 to be transmitted on one PUCCH; the terminal equipment can also multiplex the first HARQ-ACK with a second HARQ-ACK carried by one PUCCH with the longest time domain resource in the PUCCH 1 and the PUCCH 2 to be transmitted on one PUCCH; the terminal device may also multiplex the first HARQ-ACK with a second HARQ-ACK carried by one PUCCH containing the largest number of resource elements from among PUCCH 1 and PUCCH 2 for transmission on one PUCCH.

For example, assuming that the priority of the first HARQ-ACK is higher than the priority of the second HARQ-ACK, the terminal device cancels transmission of PUCCH 1 and PUCCH 2 and transmits the first PUCCH.

For another example, assuming that the priority of the first HARQ-ACK is lower than the priority of the second HARQ-ACK, the terminal device cancels transmission of the first PUCCH and transmits PUCCH 1 and PUCCH 2.

For example, assuming that the priority of the first HARQ-ACK is lower than the priority of the second HARQ-ACK, the terminal device cancels transmission of the time domain resource overlapping portion in the first PUCCH, and transmits PUCCH 1 and PUCCH 2; after the PUCCH 1 and PUCCH 2 transmission is completed, the remaining part after the time domain resource overlapping part in the first PUCCH is transmitted.

In one embodiment of the present invention, the terminal device may transmit the multiplexing of the HARQ-ACK with the low priority among the first HARQ-ACK and the second HARQ-ACK and the one with the high priority among the first HARQ-ACK and the second HARQ-ACK on one PUCCH.

For example, assuming that the priority of the first HARQ-ACK is higher than the priority of the second HARQ-ACK, the terminal device cancels transmission of PUCCH 1 and PUCCH 2, multiplexes the first HARQ-ACK with the second HARQ-ACK, and transmits on one PUCCH. For example, multiplexing is transmitted on the first PUCCH or multiplexing is transmitted on one other PUCCH than the first PUCCH, wherein the other PUCCH may be determined according to a predetermined rule.

For another example, assuming that the priority of the first HARQ-ACK is lower than the priority of the second HARQ-ACK, the terminal device cancels transmission of the first PUCCH and multiplexes the second HARQ-ACK with the first HARQ-ACK for transmission on one PUCCH. For example, multiplexing is transmitted on PUCCH 1 or PUCCH 2, or multiplexing is transmitted on another PUCCH other than PUCCH 1 and PUCCH 2, wherein the other PUCCH may be determined according to a predetermined rule.

In one embodiment of the present invention, the terminal device may transmit the multiplexing of the HARQ-ACK with the low priority among the first HARQ-ACK and the second HARQ-ACK and each HARQ-ACK with the high priority among the first HARQ-ACK and the second HARQ-ACK on the corresponding PUCCH.

For example, assuming that the priority of the first HARQ-ACK is lower than the priority of the second HARQ-ACK, the terminal device cancels transmission of the first PUCCH, multiplexes the first HARQ-ACK with the second HARQ-ACK carried by PUCCH 1 for transmission on PUCCH 1, and multiplexes the first HARQ-ACK with the second HARQ-ACK carried by PUCCH 2 for transmission on PUCCH 2.

For the case where the first PUCCH overlaps n (n is greater than 2) second PUCCHs on time domain resources and the n second PUCCHs do not overlap on time domain resources, it is assumed that the n PUCCHs are PUCCH 1, PUCCH 2, PUCCH 3, PUCCH 4, … …, and PUCCH n, respectively.

In one embodiment of the present invention, the terminal device may cancel transmission of the first PUCCH and transmit PUCCHs 1 to n.

In one embodiment of the present invention, the terminal device may cancel transmission of the time domain resource overlapping portion in the first PUCCH and transmit PUCCHs 1 to n; after the PUCCH 1 to n transmission is completed, the remaining part after the time domain resource overlapping part in the first PUCCH is transmitted.

In one embodiment of the present invention, the terminal device may cancel transmission of the first PUCCH and multiplex the first HARQ-ACK with the second HARQ-ACK carried by one PUCCH of the n PUCCHs to be transmitted on one PUCCH.

In one embodiment of the present invention, one PUCCH of the n PUCCHs may be the earliest starting symbol PUCCH of the n PUCCHs; the last PUCCH of the start symbol or the end symbol of the n PUCCHs may be used; the method can also be one PUCCH with the lowest code rate in n PUCCHs; the method can also be one PUCCH with the longest time domain resource in n PUCCHs; one PUCCH having the largest number of resource elements may be included among the n PUCCHs.

The following describes the above cases, respectively.

For example, assuming that PUCCH 1 is the PUCCH with the earliest starting symbol among n PUCCHs, the first HARQ-ACK is multiplexed with the second HARQ-ACK carried by PUCCH 1 for transmission on one PUCCH, for example, on PUCCH 1, or on another PUCCH other than PUCCH 1, where the other PUCCH may be determined according to a predetermined rule. Fig. 3 shows a first schematic diagram of PUCCH transmission provided by an embodiment of the present invention. In fig. 3, one slot contains n+1 sub-slots.

For further example, assuming that PUCCH n is the PUCCH with the latest starting symbol or ending symbol in n PUCCHs, the first HARQ-ACK is multiplexed with the second HARQ-ACK carried by PUCCH n for transmission on one PUCCH, for example, on PUCCH n, or on another PUCCH other than PUCCH n, where the other PUCCH may be determined according to a predetermined rule. Fig. 4 shows a second schematic diagram of PUCCH transmission provided by an embodiment of the present invention. In fig. 4, one slot contains n+1 sub-slots.

For further example, assuming that PUCCH 3 is the lowest rate PUCCH of the n PUCCHs, the first HARQ-ACK is multiplexed with the second HARQ-ACK carried by PUCCH 3 for transmission on one PUCCH, for example, multiplexed on PUCCH 3, or multiplexed on another PUCCH other than PUCCH 3, where the other PUCCH may be determined according to a predetermined rule. Fig. 5 shows a third schematic diagram of PUCCH transmission provided by an embodiment of the present invention. In fig. 5, one slot contains n+1 sub-slots.

For further example, assuming that PUCCH 2 is the PUCCH with the longest time domain resource among the n PUCCHs, the first HARQ-ACK is multiplexed with the second HARQ-ACK carried by PUCCH 2 to be transmitted on one PUCCH, for example, multiplexed on PUCCH 2, or multiplexed on another PUCCH other than PUCCH 2, wherein the other PUCCH may be determined according to a predetermined rule. Fig. 6 shows a fourth schematic diagram of PUCCH transmission provided by an embodiment of the present invention. In fig. 6, one slot contains n+1 sub-slots.

For further example, assuming that PUCCH 4 is the PUCCH having the largest number of resource elements among the n PUCCHs, the first HARQ-ACK is multiplexed with the second HARQ-ACK carried by PUCCH 4 for transmission on one PUCCH, for example, multiplexed on PUCCH 4, or multiplexed on another PUCCH other than PUCCH 4, wherein the other PUCCH may be determined according to a predetermined rule. Fig. 7 shows a fifth schematic diagram of PUCCH transmission provided by an embodiment of the present invention. In fig. 7, one slot contains n+1 sub-slots.

In one embodiment of the present invention, the terminal device may cancel transmission of the first PUCCH, and multiplex the first HARQ-ACK with the second HARQ-ACK carried by each of the n PUCCHs on the corresponding PUCCH for transmission.

When multiplexing the first HARQ-ACK with the second HARQ-ACK carried by each of PUCCHs 1 to n for transmission on the corresponding PUCCH, the first HARQ-ACK may be multiplexed with the second HARQ-ACK carried by PUCCH 1 for transmission on PUCCH 1, and the first HARQ-ACK may be multiplexed with the second HARQ-ACK carried by PUCCH 2 for transmission on PUCCH 2, … …, and the first HARQ-ACK may be multiplexed with the second HARQ-ACK carried by PUCCH n for transmission on PUCCH n. As shown in fig. 8, fig. 8 shows a sixth schematic diagram of PUCCH transmission provided by an embodiment of the present invention. In fig. 8, one slot contains n+1 sub-slots.

In another embodiment of the present invention, when multiplexing the first HARQ-ACK with the second HARQ-ACK carried by each of PUCCHs 1 to N for transmission on the corresponding PUCCH, the first HARQ-ACK may be multiplexed with the second HARQ-ACK carried by PUCCH 1 for transmission on the first specific PUCCH, and the first HARQ-ACK may be multiplexed with the second HARQ-ACK carried by PUCCH 2 for transmission on the second specific PUCCH, … …, and the first HARQ-ACK may be multiplexed with the second HARQ-ACK carried by PUCCH N for transmission on the nth specific PUCCH, wherein the first specific PUCCH, the second specific PUCCH, … …, and the nth PUCCH may be determined according to a predetermined rule.

Note that, the PUCCH carrying the multiplexed HARQ-ACK may be determined according to the number of bits of the multiplexed HARQ-ACK and the PUCCH resource indication (PUCCH resource indicator, PRI) corresponding to the multiplexed second HARQ-ACK according to the predetermined rule. In addition, the embodiment of the present invention does not specifically limit the determination mode of the PUCCH where the multiplexed HARQ-ACK is located, and any available determination mode may be applied to the embodiment of the present invention.

For example, assuming that the priority of the first HARQ-ACK is higher than the priority of the second HARQ-ACK, the terminal device cancels transmission of PUCCHs 1 to n and transmits the first PUCCH.

For another example, assuming that the priority of the first HARQ-ACK is lower than the priority of the second HARQ-ACK, the terminal device cancels transmission of the first PUCCH and transmits PUCCHs 1 to n.

For example, assuming that the priority of the first HARQ-ACK is lower than the priority of the second HARQ-ACK, the terminal device cancels transmission of the time domain resource overlapping portion in the first PUCCH, and transmits PUCCHs 1 to n; after the PUCCH 1 to n transmission is completed, the remaining part after the time domain resource overlapping part in the first PUCCH is transmitted.

For example, assuming that the priority of the first HARQ-ACK is higher than the priority of the second HARQ-ACK, the terminal device cancels transmission of PUCCHs 1 to n, multiplexes the first HARQ-ACK with the second HARQ-ACK, and transmits on one PUCCH. For example, multiplexing is transmitted on the first PUCCH or multiplexing is transmitted on one other PUCCH than the first PUCCH, wherein the other PUCCH may be determined according to a predetermined rule.

For another example, assuming that the priority of the first HARQ-ACK is lower than the priority of the second HARQ-ACK, the terminal device cancels transmission of the first PUCCH and multiplexes the second HARQ-ACK with the first HARQ-ACK for transmission on one PUCCH. For example, multiplexing is transmitted on any one of PUCCHs 1 to n, or multiplexing is transmitted on another one of PUCCHs other than PUCCHs 1 to n, wherein the other one of PUCCHs may be determined according to a predetermined rule.

For example, it is assumed that the priority of the first HARQ-ACK is higher than the priority of the second HARQ-ACK. The second HARQ-ACK carried by each of PUCCHs 1 to n is multiplexed with the first HARQ-ACK on one PUCCH, for example, multiplexed on the first PUCCH, or multiplexed on one other PUCCH than the first PUCCH, wherein the other PUCCH may be determined according to a predetermined rule. Fig. 9 shows a seventh schematic diagram of PUCCH transmission provided by an embodiment of the present invention.

Further exemplary, assume that the priority of the first HARQ-ACK is higher than the priority of the second HARQ-ACK. The first HARQ-ACK is multiplexed with the second HARQ-ACK carried by each of PUCCHs 1 to n, respectively, for transmission on the corresponding PUCCH.
