DETAILED DESCRIPTION

The detailed description of the appended drawings is intended as a description of the currently preferred embodiments of the present disclosure and is not intended to represent the only form in which the present disclosure may be practiced. It is to be understood that the same or equivalent functions may be accomplished by different embodiments that are intended to be encompassed within the spirit and scope of the present disclosure.

Reference will now be made in detail to some embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings. To facilitate understanding, embodiments are provided under specific network architecture and new service scenarios, such as 3rd generation partnership project (3GPP) 5G, 3GPP long term evolution (LTE) Release 8 and so on. Persons skilled in the art know very well that, with the development of network architecture and new service scenarios, the embodiments in the present disclosure are also applicable to similar technical problems.

FIG. 1 illustrates a schematic diagram of a wireless communication system 100 in accordance with some embodiments of the present application.

As shown in FIG. 1, the wireless communication system 100 includes a UE 102 and a BS 101. Although merely one BS is illustrated in FIG. 1 for simplicity, it is contemplated that the wireless communication system 100 may include more BSs in some other embodiments of the present application. Similarly, although merely one UE is illustrated in FIG. 1 for simplicity, it is contemplated that the wireless communication system 100 may include more UEs in some other embodiments of the present application.

The BS 101 may also be referred to as an access point, an access terminal, a base, a macro cell, a node-B, an enhanced node B (eNB) , a gNB, a home node-B, a relay node, or a device, or described using other terminology used in the art. The BS 101 is generally part of a radio access network that may include a controller communicably coupled to the BS 101.

The UE 102 may include computing devices, such as desktop computers, laptop computers, personal digital assistants (PDAs) , tablet computers, smart televisions (e.g., televisions connected to the Internet) , set-top boxes, game consoles, security systems (including security cameras) , vehicle on-board computers, network devices (e.g., routers, switches, and modems) , or the like. According to an embodiment of the present application, the UE 102 may include a portable wireless communication device, a smart phone, a cellular telephone, a flip phone, a device having a subscriber identity module, a personal computer, a selective call receiver, or any other device that is capable of sending and receiving communication signals on a wireless network. In some embodiments, the UE 102 may include wearable devices, such as smart watches, fitness bands, optical head-mounted displays, or the like. Moreover, the UE 102 may be referred to as a subscriber unit, a mobile, a mobile station, a user, a terminal, a mobile terminal, a wireless terminal, a fixed terminal, a subscriber station, a user terminal, or a device, or described using other terminology used in the art.

The wireless communication system 100 is compatible with any type of network that is capable of sending and receiving wireless communication signals. For example, the wireless communication system 100 is compatible with a wireless communication network, a cellular telephone network, a time division multiple access (TDMA) -based network, a code division multiple access (CDMA) -based network, an orthogonal frequency division multiple access (OFDMA) -based network, an LTE network, a 3GPP-based network, a 3GPP 5G network, a satellite communications network, a high altitude platform network, and/or other communications networks.

To improve reliability and robustness of PUCCH, a PUCCH repetition mechanism has been introduced. For example, the inter-slot PUCCH repetition scheme is already supported in R15, wherein only one beam can be used to transmit all repetitions. Meanwhile, PUCCH repetition with one or more beams or multiple TRPs may be supported both in FR1 (a low carrier frequency range) and FR2 (a high carrier frequency range, e.g., from 24.25GHz to 52.6GHz) . In the case of using multi-TRP and/or multi-panel, inter-slot PUCCH repetition with multiple beams can be a very straightforward way based on R15 to enhance the reliability and robustness of PUCCH according to some embodiments of the present application. On the other hand, although intra-slot PUCCH repetition can achieve a lower latency compared with inter-slot PUCCH repetition, no intra-slot PUCCH repetition solution has been proposed yet, especially in the case of using multi-TRP and/or multi-panel, which will be solved in embodiments of the present application.

FIG. 2 illustrates a flow chart of a method for multiplexing uplink resources in accordance with some embodiments of the present application. Although the method is illustrated in a system level by a UE in the remote side and a BS in network side (e.g., the UE 102 and BS 101 as illustrated and shown in FIG. 1) , persons skilled in the art can understand that the method implemented in the remote side and that implemented in the network side can be separately implemented and incorporated by other apparatus with the like functions.

In the exemplary method shown in FIG. 2, in step 202, the network side, e.g., a BS 101 as shown in FIG. 1 may transmit configuration information to the remote side, e.g., a UE 102, e.g., by at least one radio resource control (RRC) signaling and/or downlink control information (DCI) . Correspondingly, in step 212, the remote side may receive the configuration information from the network side. The configuration information may indicate a set of uplink resources. The set of uplink resource includes a first uplink resource, which is a first PUCCH resource (also referred to "PUCCH" in the art) configured with a number of intra-slot repetitions.

The set of uplink resource may only include the first uplink resource in some embodiments of the present application. In some other embodiments of the present application, the set of uplink resource may include other uplink resource (s) besides the first PUCCH resource, and each of the other uplink resource (s) may be a PUCCH resource or a PUSCH resource. More specifically, when an uplink resource is a PUCCH resource, it may be an intra-slot repetition PUCCH resource, inter-slot repetition PUCCH resource, or non-repetition PUCCH resource. When an uplink resource is a PUSCH resource, it may be a PUSCH resource with or without repetition, e.g., being PUSCH repetition type A or PUSCH repetition type B. Different from PUSCH repetition type A, in PUSCH repetition type B, concepts "nominal repetition" and "actual repetition" are introduced so that multiple repetitions within one slot will be identified, which can refer to TS 38.214.

For each intra-slot repetition of the first PUCCH resource, there may be at least one second uplink resource of the set of uplink resource overlapped with the first uplink resource in time domain. In some embodiments of the present application, at least one second uplink resource is a set of second PUCCH resource. The remote side, e.g., the UE does not expect the first PUCCH and any of the set of second uplink resource to start at a same position e.g., a same symbol in the time domain and include a uplink control information (UCI) type with a same priority. Thus, when determining the configuration information on the set of the uplink resource, the network side will ensure that when any of the set of second PUCCH resources includes a same UCI type priority as the first uplink resource, the first uplink resource and the second PUCCH resource (s) with the same UCI type priority are configured to have different starting positions in the time domain.

For each intra-slot repetition of the first uplink resource, when there is at least one second uplink resource of the set of uplink resource overlapped with the first uplink resource in time domain, a third uplink resource to be transmitted will be determined from the first uplink resource and the at least one second uplink resource in step 214 in the remote side, e.g. by a UE. Only the third uplink resource will be transmitted to the network side in step 216. That is, the remaining uplink resource (s) of at least one second uplink resource overlapped with the first uplink resource and the first uplink resource except the third uplink resource will not be transmitted (or will be dropped) . Please note, herein, for an uplink resource configured with repetition, only the corresponding repetition of the uplink resource overlapped with the corresponding repetition of the intra-slot repetition PUCCH resource is considered whether to be transmitted or dropped. The uplink resource (s) (including corresponding repetition) that does not overlap with the first PUCCH resource or other uplink resource (s) in the set of uplink resource will be transmitted as legacy, which will not be repeated herein.

For example, according to some embodiments of the present application, for each intra-slot repetition of the first uplink resource, when there is a set of second PUCCH resource overlapped with the first PUCCH resource, determining a third uplink resource to be transmitted may include determining whether the first PUCCH resource and any of the set of second PUCCH resource have the same UCI type priority. In the case that the first PUCCH resource and any of the set of second PUCCH resource have different UCI type priorities, an uplink resource with the highest priority within the first PUCCH resource and the set of second PUCCH resource will be determined as the third uplink resource to be transmitted. According to some embodiments of the present application, a UCI type priority rule is that the UCI type priority of hybrid automatic repeat request-Acknowledgement (HARQ-ACK) is larger than that of scheduling request (SR) , and the UCI type priority of SR is larger than that of channel state information (CSI) . Moreover, the UCI type priority of each CSI can be high or low. That is, the UCI type priority rule is UCI type priority of HARQ-ACK > SR > CSI with higher priority > CSI with lower priority. In the case that the first PUCCH resource and any of the set of second PUCCH resource have the same UCI type priority, an uplink resource starting at an earlier position in the time domain within the first PUCCH resource and the set of second PUCCH resource with the same UCI type priority of the first PUCCH resource will be determined as the third uplink resource to be transmitted.

According to some other embodiments of the present application, in the case that all the set of second PUCCH resource is inter-slot repetition PUCCH resource (s) , the first PUCCH resource will be determined as the third uplink resource to be transmitted.

According to some yet other embodiments of the present application, in the case that all the set of second PUCCH resource is either inter-slot repetition PUCCH resource or non-repetition PUCCH resource, the first PUCCH resource will be determined as the third uplink resource to be transmitted.

According to some yet other embodiments of the present application, in the case that only a part of the set of second PUCCH resource is intra-slot repetition PUCCH resource, whether the first PUCCH resource and any of the part of the set of second PUCCH resource have the same UCI type priority will determined. That is, other uplink resource (s) not being intra-slot repetition PUCCH resource in the set of second PUCCH resource even will not be considered to be transmitted. When the first PUCCH resource and any of the part of the set of second PUCCH resource have different UCI type priorities, an uplink resource with the highest priority within the first PUCCH resource and the part of the set of second PUCCH resource will be determined as the third uplink resource to be transmitted. When the first PUCCH resource and any of the part of the set of second PUCCH resource have the same UCI type priority, an uplink resource starting at an earlier position in the time domain within the first PUCCH resource and the part of the set of second PUCCH resource with the same UCI type priority of the first PUCCH resource will be determined as the third uplink resource to be transmitted.

In some embodiments of the present application, when the at least one uplink resource overlapped with the first PUCCH resource is at least one PUSCH resource (also referred to as PUSCH or PUSCH transmission) , the first PUCCH resource will be determined as the third uplink resource to be transmitted. That is, the overlapped at least one PUSCH resource will not be transmitted.

In some embodiments of the present application, the at least one second uplink resource (s) overlapped with the first PUCCH resource may include PUCCH resource (s) and PUSCH resource (s) simultaneously. In this situation, according to some embodiments of the present application, the step for determining the third uplink resource to be transmitted or received will be firstly performed among the first PUCCH resource and the PUCCH resource (s) overlapped with the first PUCCH resource to obtain an intermediate PUCCH resource (referred to as the first determining step) , and then performed between the intermediate PUCCH resource and the PUSCH resource (s) to finally determine the third uplink resource (referred to as the second determining step) . The first determining step can be performed in the same way as that for determining the third uplink resource from a set of second PUCCH resource overlapped with the first PUCCH resource and the first PUCCH resource according to an embodiment of the present application. The second determining step can be performed in the same way as that for determining the third uplink resource from the first PUCCH resource and at least one PUSCH resource overlapped with the first PUCCH resource according to an embodiment of the present application.

Similarly, in the network side, for each intra-slot repetition of the first uplink resource, when there is at least one second uplink resource of the set of uplink resource overlapped with the first uplink resource in time domain, determining a third uplink resource to be received from the first uplink resource and the at least one second uplink resource in step 204, which is consistent with the remote side and will not be repeated. In step 206, only the third uplink resource is received.

Based on the above basic solutions, more details will be illustrated in various embodiments hereafter. Persons skilled in the art should understand that the first uplink resource (e.g. PUCCH resource etc. ) , second uplink resource and third uplink resource are only for illustrating the solutions of the present application, and should not be limited to specific uplink resource (s) . For example, regarding the first PUCCH resource with intra-slot repetition, there may be two or more PUCCH resources with intra-slot repetition indicated in the configuration information, any PUCCH resource with intra-slot repetition can be regarded as the first PUCCH resource.

As stated above, the uplink resource (s) overlapped with the first PUCCH resource with intra-slot repetition may be at least one of PUCCH resource without repetition, PUCCH resource with intra-slot repetition, PUCCH resource with inter-slot repetition, and PUSCH resource. Various multiplexing schemes (or solutions) in all these overlapped cases would be discussed in the following.

Generally, in any scheme as stated above, the network side will ensure that when any second PUCCH resource overlapped with the first PUCCH resource includes a same UCI type priority as the first uplink resource, the first uplink resource and the second PUCCH resource are configured to have different starting positions in the time domain.

Case 1: a first PUCCH resource with intra-slot repetition overlaps with a set of second PUCCH resource in a slot

Scheme 1 in Case 1: Determining the uplink resource to be transmitted is based on the UCI type priority first and then starting position in the time domain, while not considering the type of the second PUCCH resource.

According to some embodiments of the present application, for each overlapped repetition of the first PUCCH resource, when the first PUCCH resource and any of the set of second PUCCH resources do not include a UCI with the same priority, the uplink resource with the highest priority within the first PUCCH resource and the set of second PUCCH resource will be transmitted. The remaining uplink resource (s) including a UCI with lower priority (s) will be dropped, i.e., not to be transmitted. On the other hand, for each overlapped repetition of the first PUCCH resource, when the first PUCCH resource and any of the set of second PUCCH resources include a UCI with the same priority, the uplink resource starting at an earlier position, e.g., the earlier starting symbol in the time domain within the first PUCCH resource and any of the set of second PUCCH resource with the same UCI type priority of the first PUCCH resource will be transmitted. The remaining uplink resource (s) starting at later position (s) will be dropped, i.e., not to be transmitted.

FIG. 3 illustrates an exemplary diagram of a PUCCH resource with intra-slot repetition multiplexing with other PUCCH resources by Scheme 1 according to some embodiments of the present application.

Referring to FIG. 3, there are two PUCCH resources, e.g., PUCCH resource 1 and PUCCH resource 2 configured with intra-slot repetition in slot n. Besides, there is another PUCCH resource, e.g., PUCCH resource 3 not configured with repetition in slot n. UCI 1-3 with priority 1-3 are carried in PUCCH resource 1-3 respectively, wherein the order of the three UCI type priorities is priority 1>priority 2 >priority 3. As shown in FIG. 3, regarding PUCCH resource 1, the first repetition of PUCCH resource 1 is overlapped with the first repetition of PUCCH resource 2 and PUCCH resource 3; and the second repetition of PUCCH resource 1 is overlapped with PUCCH resource 3. Regarding PUCCH resource 2, the first repetition of PUCCH resource 2 is overlapped with the first repetition of PUCCH resource 1 and PUCCH resource 3, and the second repetition of PUCCH resource 2 is overlapped with PUCCH resource 3.

According to Scheme 1, for each repetition of PUCCH resource 1, since UCI 1 in PUCCH resource 1 has the highest priority compared with PUCCH resource 2 and PUCCH resource 3, the two repetitions of PUCCH resource 1 will be transmitted while the first repetition of PUCCH resource 2 and PUCCH resource 3 will be dropped. For the second repetition of PUCCH resource 2, since UCI 2 in PUCCH resource 2 has a higher priority than PUCCH resource 3, the second prepetition of PUCCH resource 2 will be transmitted while PUCCH resource 3 will be dropped (only for illustrating the principle of Scheme 1, which actually has been determined not to be transmitted due to overlapping with PUCCH resource 1) .

Based on Scheme 1, the type of the second PUCCH resource overlapped with the first PUCCH resource configured with intra-slot repetition may also be considered in some exemplary schemes of the present application e.g., Scheme 2 and Scheme 3 illustrated in the following.

For example, according to some embodiments of the present application, in the case that all the set of second PUCCH resource is inter-slot repetition PUCCH resource, the method includes determining the first PUCCH resource as the third uplink resource to be transmitted. According to some other embodiments of the present application, in the case that all the set of second PUCCH resource is either inter-slot repetition PUCCH resource or non-repetition PUCCH resource, the method includes determining the first PUCCH resource as the third uplink resource to be transmitted. According to some yet other embodiments of the present application, when only a part of the set of second PUCCH resource is intra-slot repetition PUCCH resource, the method includes determining whether the first PUCCH resource and any of the part of the set of second PUCCH resource have the same UCI type priority. Accordingly, in the case that the first PUCCH resource and any of the part of the set of second PUCCH resource have different UCI type priorities, the method includes determining an uplink resource with the highest priority within the first PUCCH resource and the part of the set of second PUCCH resource as the third uplink resource to be transmitted. In the case that the first PUCCH resource and any of the part of the set of second PUCCH resource have the same UCI type priority, the method includes determining an uplink resource starting at an earlier position in the time domain within the first PUCCH resource and the part of the set of second PUCCH resource with the same UCI type priority of the first PUCCH resource as the third uplink resource to be transmitted.

Scheme 2: Firstly, all the PUCCH resources with inter-slot repetition in the set of second PUCCH resource will not be transmitted. When all the PUCCH resources in the set of second PUCCH resource are PUCCH resources with inter-slot repetition, the first PUCCH resource will be transmitted. When the set of second PUCCH resource still includes other PUCCH resource (s) excluding the PUCCH resource (s) with inter-slot repetition, a further determining scheme similar to Scheme 1 will be performed on the first PUCCH resource and the remaining second PUCCH resources in the set of second PUCCH resource excluding all the PUCCH resource (s) with inter-slot repetition.

For example, according to some embodiments of the present application, for each overlapped repetition of the first PUCCH resource, when the first PUCCH resource and any of the remaining second PUCCH resources do not include a UCI with the same priority, the uplink resource with the highest priority within the first PUCCH resource and the remaining second PUCCH resource will be transmitted. On the other hand, for each overlapped repetition of the first PUCCH resource, when the first PUCCH resource and any of the remaining second PUCCH resources include a UCI with the same priority, the uplink resource starting at an earlier position, e.g., the earliest starting symbol in the time domain within the first PUCCH resource and any of the set of second PUCCH resource with the same UCI type priority will be transmitted.

FIG. 4 illustrates an exemplary diagram of a PUCCH resource with intra-slot repetition multiplexing with other PUCCH resources by Scheme 2 according to some embodiments of the present application.

Referring to FIG. 4, there are two PUCCH resources, e.g., PUCCH resource 1 and PUCCH resource 2 configured with intra-slot repetition in slot n. Besides, there is another PUCCH resource, e.g., PUCCH resource 3 configured with inter-slot repetition, wherein the first repetition of PUCCH resource 3 is in slot n and the second repetition of PUCCH resource 3 is in slot n+1. UCI 1-3 with priority 3-1 are carried in PUCCH resource 1-3 respectively, wherein the order of the three UCI type priority is priority 1>priority 2 > priority 3. As shown in FIG. 4, regarding PUCCH resource 1, the first repetition of PUCCH resource 1 is overlapped with the first repetition of PUCCH resource 2 and PUCCH resource 3, and the second repetition of PUCCH resource 1 is overlapped with the first repetition of PUCCH resource 3. Regarding PUCCH resource 2, the first repetition of PUCCH resource 2 is overlapped with the first repetition of PUCCH resource 1 and PUCCH resource 3, and the second repetition of PUCCH resource 2 is overlapped with the first repetition of PUCCH resource 3.

According to Scheme 2, for the first repetition of PUCCH resource 1, the first repetition of PUCCH resource 3 will be dropped due to being a PUCCH resource with inter-slot repetition. Then, a further determining scheme similar to Scheme 1 will be applied to PUCCH resource 1 and PUCCH resource 2. Since UCI 2 in PUCCH resource 2 has a higher priority than UCI 1 in PUCCH resource 1, the first repetition of PUCCH resource 2 will be transmitted while PUCCH resource 1 will be dropped. For the second repetition of PUCCH resource 1, since the first repetition of PUCCH resource 3 has been excluded and there is no other overlapped PUCCH resource, the second repetition of PUCCH resource 1 will be transmitted. Similarly, for the second repetition of PUCCH resource 2, since the first repetition of PUCCH resource 3 has been excluded and there is no other overlapped PUCCH resource, the second repetition of PUCCH resource 2 will be transmitted.

Scheme 3: Firstly, all the PUCCH resources with inter-slot repetition or without repetition in the set of second PUCCH resource will not be transmitted. When all the PUCCH resources in the second PUCCH resource are PUCCH resources with inter-slot repetition or without repetition, the first PUCCH resource will be transmitted. When the set of second PUCCH resource still includes other PUCCH resource (s) excluding the PUCCH resource (s) with inter-slot repetition or without repetition, a further determining scheme similar to Scheme 1 will be performed on the first PUCCH resource and the remaining second PUCCH resources in the set of second PUCCH resource excluding all the PUCCH resource (s) with inter-slot repetition or without repetition.

For example, according to some embodiments of the present application, for each overlapped repetition of the first PUCCH resource, when the first PUCCH resource and any of the remaining second PUCCH resources do not include a UCI with the same priority, the uplink resource with the highest priority within the first PUCCH resource and the remaining second PUCCH resource will be transmitted. On the other hand, for each overlapped repetition of the first PUCCH resource, when the first PUCCH resource and any of the remaining second PUCCH resources include a UCI with the same priority, the uplink resource starting at an earlier position, e.g., the earlier starting symbol in the time domain within the first PUCCH resource and the set of second PUCCH resource with the same UCI type priority of the first PUCCH resource will be transmitted.

FIG. 5 illustrates an exemplary diagram of a PUCCH resource with intra-slot repetition multiplexing with other PUCCH resources by Scheme 3 according to some embodiments of the present application.

Referring to FIG. 5, PUCCH resource 1 is configured without repetition in slot n, PUCCH resource 2 is configured with intra-slot repetition in slot n, and PUCCH resource 3 is configured with inter-slot repetition, wherein the first repetition of PUCCH resource 3 is in slot n and the second repetition of PUCCH resource 3 is in slot n+1. UCI 1-3 with priority 3-1 are carried in PUCCH resource 1-3 respectively, wherein the order of the three UCI type priority is that priority 1 > priority 2 > priority 3. As shown in FIG. 5, regarding PUCCH resource 2 configured with intra-slot repetition, the first repetition of PUCCH resource 2 is overlapped with the first repetition of PUCCH resource 3 and PUCCH resource 1, and the second repetition of PUCCH resource 2 is overlapped with the first repetition of PUCCH resource 3.

According to Scheme 3, for the first repetition of PUCCH resource 2, PUCCH resource 1 and the first repetition of PUCCH resource 3 in slot n will be dropped. Since there is only PUCCH resource 2 excluding PUCCH resource 1 and PUCCH resource 3 in slot n, the first repetition of PUCCH resource 2 will be transmitted. Similarly, the second repetition of PUCCH resource 2 will also be transmitted.

Case 2: a first PUCCH resource with intra-slot repetition overlaps with at least one PUSCH resource in a slot.

According to some embodiments of the present application, for a repetition of the first PUCCH resource, when a first PUCCH resource with intra-slot repetition overlaps with at least one PUSCH resource in a slot, the first PUCCH resource will be transmitted while the overlapped PUSCH resource will not be transmitted in the slot.

For example, for a repetition of the first PUCCH resource, a PUSCH resource overlapped with the first PUCCH resource in a slot may be a PUSCH repetition Type A with repetition number not smaller than 1 (when the PUSCH repetition number is 1, the PUSCH transmission is actually not repeated) . In this case, for any overlapped repetition of the first PUCCH resource, the PUCCH resource will be transmitted, while the overlapped repetition of the PUSCH resource will not be transmitted.

In another example, for a repetition of the first PUCCH resource, a PUSCH resource overlapped with the first PUCCH resource in a slot be a PUSCH repetition Type B with actual repetition number not smaller than 1 (when the PUSCH repetition number is 1, the PUSCH transmission is actually not repeated) . In this case, all the overlapped intra-slot repetitions of the first PUCCH resource are transmitted and all overlapped actual repetitions of the PUSCH are not transmitted in the slot.

FIG. 6 illustrates an exemplary diagram of a PUCCH resource with intra-slot repetition multiplexing with at least one PUSCH according to some embodiments of the present application.

Referring to FIG. 6, there is a PUSCH resource configured with repetition Type B e.g., PUSCH 1, which has two nominal repetitions, e.g., nominal repetition 0 and nominal repetition 1 and three actual repetitions in slot n and slot n+1. Besides, there is a PUCCH resource, e.g., PUCCH resource 1 configured with 2 intra-slot repetitions in slot n. As shown in FIG. 6, the first repetition of PUCCH resource 1 is overlapped with the first actual repetition of PUSCH resource 1, and the second repetition of PUCCH resource 1 is overlapped with the second actual repetition of PUSCH 1.
