[0025] Detailed Description The present disclosure will now be described in detail with reference to the accompanying drawings, which form a part hereof, and which show, by way of illustration, specific embodiments. It should be noted, however, that the disclosure may be embodied in a variety of different forms, and therefore, the subject matter covered or claimed should not be construed as limited to any of the embodiments set forth below.

[0026] Throughout this specification and claims, terms may have nuanced meanings suggested or implied in context beyond their explicitly stated meaning. Similarly, the phrases "in one embodiment" or "in some embodiments" used herein do not necessarily refer to the same embodiment, and the phrases "in another embodiment" or "in other embodiments" used herein do not necessarily refer to different embodiments.

For example, the claimed subject matter is intended to include, in whole or in part, example embodiments or combinations of implementations.

[0027] Generally, terms may be understood, at least in part, from their use in context. For example, terms such as "and," "or," and "and / or," as used herein, may include a variety of meanings that may depend, at least in part, on the context in which such terms are used. Typically, "or," when used to relate a list such as A, B, or C, is intended to mean A, B, and C, which are used herein in an inclusive sense, and A, B, or C, which are used herein in an exclusive sense. Furthermore, as used herein, the terms "one or more" or "at least one" may be used to describe any feature, structure, or characteristic in a singular sense, or may be used to describe a combination of features, structures, or characteristics in a plural sense, depending, at least in part, on the context.

[0028] The present disclosure describes methods and devices for uplink control information (UCI) multiplexing for a physical uplink shared channel (PUSCH) and a physical uplink control channel with repetition (PUCCH).

[0029] New generation (NG) mobile communication systems are moving the world towards an increasingly connected and networked society. High-speed and low-latency wireless communications rely on efficient network resource management and allocation between user equipment and radio access network nodes (including but not limited to radio base stations). New generation networks are expected to provide high-speed, low-latency, and ultra-reliable communication capabilities to meet the demands of various industries and users.

[0030] Some existing wireless communication schemes may support PUCCH repetition. One of the main purposes of supporting PUCCH repetition is to improve PUCCH reliability and coverage. A PUCCH repetition factor is generally configured or indicated as 2, 4, or 8. Thus, after a PUCCH with repetition is triggered, the PUCCH is repeatedly transmitted 2, 4, or 8 times according to the configured or indicated repetition factor.

[0031] In some implementations, for a PUCCH with a repetition factor N (N is a positive integer greater than 1), the slot in which the first PUCCH repetition is located is generally configured or indicated to the user equipment (UE) by a base station. In a time division duplex (TDD) cell, the slot for the remaining PUCCH repetitions may be determined based on the following rule: If an UL symbol or flexible symbol can be provided in the slot, the UL symbol or flexible symbol is the same as the starting symbol configured for the PUCCH (e.g., the symbol index in the slot is the same), and consecutive UL symbols or flexible symbols can be provided in the slot starting from an uplink (UL) symbol or flexible symbol, and the number of consecutive UL symbols or flexible symbols is equal to or greater than the number of symbols configured for the PUCCH, then the slot is determined for the remaining PUCCH repetitions. In some implementations, in the determined slot, the same PUCCH resource as that used by the first PUCCH repetition can be used for the remaining PUCCH repetitions.

[0032] In some implementations, based on existing specifications, if a PUCCH transmission with repetition overlaps with a PUSCH transmission with or without repetition in the time domain within a slot, the PUCCH transmission is transmitted but the PUSCH transmission is not. That is, the PUSCH transmission is discarded, which may lead to some problems / issues, such as inefficient transmission. As another example, when UCI multiplexing is adopted, the possibility of UCI joint decoding becoming unavailable easily arises. For example, in some implementations, if a UE transmits a PUCCH over a first number of slots and the UE transmits a PUSCH with repetition type A or transport block (TB) processing over multiple slots over a second number of slots, and the PUCCH transmission overlaps with a PUSCH transmission in one or more slots, and a certain set of conditions for multiplexing UCI in the PUSCH is met in the overlapping slot, the UE transmits the PUCCH and does not transmit the PUSCH in the overlapping slot. The first number of slots is greater than one slot. For example, in some other implementations, if a UE transmits a PUCCH over a first number of slots and the UE transmits a PUSCH with repetition type B over a second number of slots, and the PUCCH transmission overlaps with actual PUSCH repetitions in one or more slots, and a certain set of conditions for multiplexing UCI in the PUSCH is met for the overlapping actual PUSCH repetitions, then the UE transmits the PUCCH and does not transmit the overlapping actual PUSCH repetitions.

The radio network node may include a network base station, which may be a Node B (NB, e.g., gNB) in a mobile communication context. Each of the UEs may communicate wirelessly with the radio network node via one or more radio channels 115 for downlink / uplink communication. For example, a first UE 110 may communicate wirelessly with the radio network node 118 via a channel including multiple radio channels for a certain period of time. The network base station 118 may send higher layer signaling to the UE 110. The higher layer signaling may include configuration information for communication between the UE and the base station. In one implementation, the higher layer signaling may include a radio resource control (RRC) message.

The PUCCH repetition may not be transmitted. That is, the UCI in the PUCCH transmission is multiplexed onto the PUSCH transmission that overlaps with the PUCCH transmission, and the PUCCH transmission is not transmitted.

[0062] For the first set of situations, in some implementations, when the PUCCH transmission and the PUSCH transmission have the same repetition factor and the same slot, and the PUCCH repetitions of the PUCCH transmission and the PUSCH repetitions of the PUSCH transmission overlap within the slot in the time domain, UCI multiplexing is performed on the PUCCH transmission and the PUSCH transmission. The detailed operation is that UCI multiplexing is performed on the PUCCH repetitions of the PUCCH transmission and the PUSCH repetitions of the PUSCH transmission in each overlapping slot. After UCI multiplexing is performed, the PUCCH repetitions are not transmitted in the overlapping slots, the PUSCH repetitions are transmitted, and the UCI is transmitted in the PUSCH repetitions.

[0063] As a non-limiting example, as shown in FIG. 5, a PUCCH transmission with a repetition factor of 4 is determined to start in slot n+3, where the first PUCCH repetition 510 is in slot n+3. According to an existing mechanism, slots n+4, n+8, and n+9 are determined for the remaining repetitions of the PUCCH transmission. In the determined slots, the same PUCCH resource is used for different repetitions of the PUCCH transmission. A PUSCH transmission with a repetition factor of 4 is determined to start in slot n+3, where the first PUSCH repetition 520 is in slot n+3. According to an existing mechanism, slots n+4, n+8, and n+9 are determined for the remaining repetitions of the PUSCH transmission. In the determined slots, the same PUSCH resource is used for different repetitions of the PUSCH transmission.

[0064] In various embodiments / implementations of the present disclosure, the "first" iteration of a PUCCH / PUSCH transmission with repetitions may refer to the "starting" iteration or the "earliest" iteration in the PUCCH / PUSCH transmission with repetitions.

[0065] The PUCCH transmission may overlap with the PUSCH transmission in the time domain within each determined slot. That is, each repetition of the PUCCH transmission overlaps with a PUSCH repetition of the PUSCH transmission in the time domain within the corresponding slot. "Overlapping" may refer to full overlap, where each repetition of the PUCCH transmission overlaps with a PUSCH repetition of the PUSCH transmission in the time domain over all symbols of either repetition within the corresponding slot, or may refer to partial overlap, where each repetition of the PUCCH transmission overlaps with a PUSCH repetition of the PUSCH transmission in the time domain over at least one symbol within the corresponding slot.

[0066] Referring to Figure 5, UCI in a PUCCH transmission is multiplexed onto the PUCCH transmission. For example, UCI in a PUCCH repetition of a PUCCH transmission is multiplexed onto a repetition of a PUSCH transmission that overlaps the PUCCH repetition. That is, if the first PUCCH repetition of a PUCCH transmission overlaps with the first PUSCH repetition of a PUSCH transmission in slot n+3, UCI in the first PUCCH repetition is multiplexed onto the first PUSCH repetition. If the second PUCCH repetition of a PUCCH transmission overlaps with the second PUSCH repetition of a PUSCH transmission in slot n+4, UCI in the second PUCCH repetition is multiplexed onto the second PUSCH repetition. If the third PUCCH repetition of a PUCCH transmission overlaps with the third PUSCH repetition of a PUSCH transmission in slot n+8, UCI in the third PUCCH repetition is multiplexed onto the third PUSCH repetition. If the fourth PUCCH repetition of a PUCCH transmission overlaps with the fourth PUSCH repetition of a PUSCH transmission in slot n+9, the UCI in the fourth PUCCH repetition is multiplexed onto the fourth PUSCH repetition. In some implementations, not all repetitions of a PUCCH transmission are transmitted. All repetitions of a PUSCH transmission are transmitted. In some implementations, the UCI in each repetition of a PUCCH transmission is the same.

[0067] In various embodiments / implementations of the present disclosure, the "first" PUCCH / PUSCH repetition may refer to the "earliest" PUCCH / PUSCH repetition, e.g., the PUCCH / PUSCH repetition in slot n+3 of FIG. 5. The "second" PUCCH / PUSCH repetition may refer to the "second earliest" PUCCH / PUSCH repetition, e.g., the PUCCH / PUSCH repetition in slot n+4 of FIG. 5. The "third" PUCCH / PUSCH repetition may refer to the "third earliest" PUCCH / PUSCH repetition, e.g., the PUCCH / PUSCH repetition in slot n+8 of FIG. 5. The "fourth" PUCCH / PUSCH repetition may refer to the "fourth earliest" PUCCH / PUSCH repetition, e.g., the PUCCH / PUSCH repetition in slot n+9 of FIG. 5.

[0068] In some implementations, the slots corresponding to all repetitions of a PUCCH transmission with repetition or a PUSCH transmission with repetition are determined as shown in FIG.

[0069] In some implementations, if a PUCCH transmission without repetition overlaps with multiple PUSCHs without repetition within a slot in the time domain, the UCI in the PUCCH transmission is multiplexed into the PUSCH transmission with the earliest starting symbol.

[0070] In some implementations, when a PUCCH transmission with repetition overlaps with multiple PUSCH transmissions in a slot in the time domain, the following may be used to determine into which PUSCH transmission the UCI in the PUCCH transmission should be multiplexed, where the multiple PUSCH transmissions include PUSCH repetitions and PUSCH transmissions without repetitions.

[0071] If the slot is the slot in which the first PUCCH repetition of a PUCCH transmission is located, i.e., if the first PUCCH repetition overlaps with multiple PUCCH transmissions in the slot in the time domain, the following applies: If the repetition factor of the PUSCH transmission is greater than or equal to the repetition factor of the PUCCH transmission (which means that the slot of the PUCCH transmission with repetition is a subset of the slot of the PUSCH transmission with repetition), and if the PUSCH transmission has the earliest starting symbol in the slot and is an initial PUSCH transmission, then the PUSCH transmission is selected. If there are multiple PUSCH transmissions that satisfy the above condition, then any one PUSCH transmission is selected from the multiple PUSCH transmissions that satisfy the condition. Here, for PUSCH transmissions with repetition, the PUSCH transmission is the initial PUSCH transmission, which refers to the first PUSCH repetition. For PUSCH transmissions without repetition, the PUSCH transmission is the initial PUSCH transmission, which refers to the PUSCH transmission itself.

[0072] If the slot is a slot in which a PUCCH repetition other than the first PUCCH repetition is located, selecting the PUSCH transmission multiplexed with the first PUCCH repetition applies even if the PUSCH transmission does not have the earliest starting symbol in the slot.

[0073] In the first scenario, the UCIs in all repetitions of a PUCCH transmission are multiplexed onto different repetitions of the same PUSCH transmission. Because these PUSCH repetitions correspond to the same PUSCH transmission, they use the same PUSCH resource, modulation, and beta offset. In this way, the UCIs multiplexed onto these PUSCH repetitions can obtain the same resource and modulation. Therefore, the UCIs multiplexed onto these PUSCH repetitions can still be jointly demodulated and decoded to obtain a gain.

[0074] In a second situation set, if all repetitions of a PUCCH transmission with repetitions overlap in the time domain with all or some of the repetitions of a PUSCH transmission, each with repetitions, in one or more slots, the UCI in the PUCCH transmission is multiplexed with the PUSCH transmission in the one or more slots that they overlap in the time domain. The second situation set may include the following situation subsets:

[0075] In a first subset of situations, if a PUCCH transmission with repetitions and a PUSCH transmission with repetitions have the same starting slot, and if necessary, the number of repetitions of the PUCCH transmission is less than the number of repetitions of the PUSCH transmission (which means that the slots of the PUCCH transmission with repetitions are a subset of the slots of the PUSCH transmission with repetitions), and in each slot in which a PUCCH repetition is located, the repetitions of the PUCCH transmission each overlap in the time domain with the repetitions of the PUSCH transmission, then the UCI in the PUCCH transmission is multiplexed onto the PUSCH transmission in one or more slots where they overlap in the time domain.

[0076] In the non-limiting example shown in Figure 6, the PUCCH transmission with repetitions has the same starting slot n+3 as the PUSCH transmission with repetitions, the repetition factor of the PUCCH transmission is 2 less than the repetition factor of the PUSCH transmission is 4, each repetition of the PUCCH transmission overlaps in the time domain with one repetition of the PUSCH transmission in each of slots n+3 and n+4, and UCI in the PUCCH transmission is multiplexed onto the repetition of the PUSCH transmission in each of slots n+3 and n+4. In this way, no PUCCH repetitions are transmitted in slots n+3 and n+4.

[0077] In some implementations, since the number of repetitions of a PUCCH transmission is less than the number of repetitions of a PUSCH transmission, the following operation may be used to determine how the remaining repetitions of a PUSCH transmission, such as those in slot n+8 and slot n+9, should be processed. The operation is as follows: UCI in a PUCCH transmission continues to be multiplexed onto the remaining PUSCH repetitions, i.e., UCI is also multiplexed onto the repetitions of a PUSCH transmission in slot n+8 and slot n+9, respectively. In this way, UCI is actually transmitted four times. Alternatively, the remaining PUSCH repetitions of a PUSCH transmission are transmitted directly in slot n+8 and slot n+9, i.e., UCI is not multiplexed onto the remaining PUSCH repetitions. In this way, UCI is actually transmitted two times.

[0078] In a second subset of situations, if the PUCCH transmission with repetitions and the PUSCH transmission with repetitions have different starting slots, and if necessary the number of repetitions of the PUCCH transmission is less than the number of repetitions of the PUSCH transmission (which means that the slots of the PUCCH transmission with repetitions are a subset of the slots of the PUSCH transmission with repetitions), and a PUCCH repetition overlaps in the time domain with one of the repetitions of the PUSCH transmission within each slot in which a repetition of the PUCCH transmission is located, then the UCI in the PUCCH transmission is multiplexed onto the PUSCH transmission in one or more slots that overlap in the time domain.

[0079] In another non-limiting example shown in FIG. 7, a PUCCH transmission with a repetition factor of 2 begins in slot n+8. Similarly, a PUSCH transmission with a repetition factor of 4 begins in slot n+3, and the repetition factor of the PUCCH transmission is smaller than the repetition factor of the PUSCH transmission. The first and second PUCCH repetitions of the PUCCH transmission are in slot n+8 and slot n+9, respectively. The first PUCCH repetition overlaps with one PUSCH repetition of the PUSCH transmission in the time domain. The second PUCCH repetition overlaps with another PUSCH repetition of the PUSCH transmission in the time domain. Therefore, UCI in the PUCCH transmission is multiplexed with the PUSCH transmissions in slot n+8 and slot n+9, respectively. That is, UCI in the first PUCCH repetition is multiplexed with one PUSCH repetition of the PUSCH transmission in slot n+8. The UCI in the second PUCCH repetition is multiplexed onto another PUSCH repetition of the PUSCH transmission in slot n + 9. In this way, the first PUCCH repetition and the second PUCCH repetition are not transmitted in slots n + 8 and n + 9. No PUSCH repetition of the PUSCH transmission is transmitted in slots n + 8 and n + 9.

[0080] In some implementations, since the number of repetitions of a PUCCH transmission is less than the number of repetitions of a PUSCH transmission, the following operation may be used to determine how to process the remaining repetitions of a PUSCH transmission, such as those in slot n+3 and slot n+4. The operation is as follows: UCI in a PUCCH transmission is multiplexed onto the first and second PUSCH repetitions, respectively; that is, UCI is also multiplexed onto the repetitions of a PUSCH transmission in slot n+3 and slot n+4, respectively. In this way, UCI is actually transmitted four times. Alternatively, the first and second PUSCH repetitions of a PUSCH transmission are directly transmitted in slot n+3 and slot n+4; that is, UCI is not multiplexed onto the first and second PUSCH repetitions. In this way, UCI is actually transmitted twice.

[0081] In the third subset of situations, when multiple PUCCH transmissions with repetitions overlap with one PUSCH transmission with repetitions in the time domain, and if necessary, the number of repetitions of the PUCCH transmission is less than the number of repetitions of the PUSCH transmission (which means that the slots of the multiple PUCCH transmissions with repetitions are a subset of the slots of the PUSCH transmissions with repetitions), and in each slot in which each PUCCH repetition of the multiple PUCCH transmissions is located, each PUCCH repetition overlaps with one repetition of the PUSCH transmission in the time domain, the UCI in each PUCCH repetition is multiplexed into one repetition of the PUSCH transmission that overlaps with the PUCCH repetitions in those overlapping slots, or the UCI of the PUCCH transmission with the earliest start slot among the multiple PUCCH transmissions is multiplexed into one repetition of the PUSCH transmission that overlaps with the PUCCH repetition of the PUCCH transmission in the overlapping slot, and the remaining PUCCH transmissions are not transmitted, and the UCI in them is not multiplexed into the PUSCH transmission.

[0082] In another non-limiting example shown in FIG. 8 , a first PUCCH (PUCCH1) transmission with a repetition factor of 2 begins in slot n+3. A second PUCCH (PUCCH2) transmission with a repetition factor of 2 begins in slot n+8. A PUSCH transmission with a repetition factor of 4 begins in slot n+3, where the repetition factor of the PUCCH transmission is 2 less than the repetition factor of the PUSCH transmission, 4. The PUCCH1 repetition overlaps in the time domain with two repetitions of the PUSCH transmission in slots n+3 and n+4, where the PUCCH1 repetition is located. Similarly, the PUCCH2 repetition overlaps in the time domain with two other repetitions of the PUSCH transmission in slots n+8 and n+9, where the PUCCH2 repetition is located. In this way, UCI in the PUCCH1 transmission is multiplexed into two repetitions of the PUSCH transmission in slots n+3 and n+4, respectively. The UCI in the PUCCH2 transmission is multiplexed into the other two repetitions of the PUSCH transmission in slot n+8 and slot n+9, respectively. Thus, no PUCCH1 transmission is transmitted in slot n+3 and slot n+4. No PUCCH2 transmission is transmitted in slot n+8 and slot n+9.

[0083] In some implementations, different repetitions of a PUSCH transmission are multiplexed with UCI in different PUCCH transmissions. If these UCI are HARQ-ACK information, the UL Downlink Allocation Index (DAI) value in the UL grant corresponding to the PUSCH transmission is equal to the maximum number of HARQ-ACK bits in the different HARQ-ACK information. These different HARQ-ACK information are multiplexed into different repetitions of the PUSCH transmission based on the UL DAI value.

[0084] In some implementations, the start slot of PUCCH1 transmission is earlier than the start slot of PUCCH2 transmission, so UCI in PUCCH2 transmission is not multiplexed into PUSCH transmission and PUCCH2 transmission is not transmitted. UCI in PUCCH1 transmission is multiplexed into repeats of PUSCH transmission in slot n+3 and slot n+4, respectively. PUCCH1 transmission is not transmitted in slot n+3 and slot n+4. In some implementations, UCI multiplexing may not be optimal and still work.

[0085] In the case of a fourth subset of situations, if a PUCCH transmission with repetitions overlaps with multiple PUSCH transmissions with or without repetitions in the time domain, and if necessary, the number of repetitions of the PUCCH transmission is greater than the number of repetitions of each PUSCH transmission (which means that the slots of the multiple PUSCH transmissions with repetitions are a subset of the slots of the PUCCH transmissions with repetitions), and in the slot in which each PUCCH repetition of the PUCCH transmission is located, each PUCCH repetition overlaps with one PUSCH transmission without repetitions or one PUSCH repetition corresponds to multiple PUSCH transmissions in the time domain, then the UCI in each repetition of the PUCCH transmission is multiplexed into one PUSCH transmission without repetitions or one PUSCH transmission that overlaps with each repetition of the PUCCH transmission, respectively. In some implementations, no PUCCH transmission is transmitted.

[0086] In another non-limiting example shown in FIG. 9 , a PUCCH transmission with a repetition factor of 4 starts at slot n+3, with its repetitions occurring in slots n+3, n+4, n+8, and n+9, respectively. A PUSCH1 transmission with a repetition factor of 2 starts at slot n+3, with its repetitions occurring in slots n+3 and n+4. A PUSCH2 transmission with a repetition factor of 2 starts at slot n+8, with its repetitions occurring in slots n+8 and n+9. In each slot in which a PUCCH repetition occurs, each PUCCH repetition overlaps in the time domain with one PUSCH1 repetition or one PUSCH2 repetition, respectively. That is, each PUCCH repetition overlaps with a PUSCH transmission in the time domain. Therefore, UCI in a PUCCH transmission is multiplexed into the PUSCH transmission that overlaps with the PUCCH transmission in each overlapping slot. That is, in slots n+3 and n+4, UCI in PUCCH transmission is multiplexed onto two PUSCH1 repetitions of PUSCH1 transmission, respectively. In slots n+8 and n+9, UCI in PUCCH transmission is multiplexed onto two PUSCH2 repetitions of PUSCH2 transmission, respectively. PUCCH transmission is not transmitted in slots n+3, n+4, n+8, and n+9.

[0087] In some implementations, when UCI in a PUCCH transmission with repetition is multiplexed onto different PUSCH transmissions, these different PUSCH transmissions must satisfy at least one of the following conditions for better joint decoding between UCI multiplexed onto these different PUSCH transmissions: The conditions include the same modulation mode, the same UL DAI value, and / or the same beta offset for the same UCI type.

[0088] In some implementations, when UCI in a PUCCH transmission with repetition is multiplexed onto different PUSCH transmissions, these different PUSCH transmissions must satisfy at least two of the following conditions for better joint decoding between UCI multiplexed onto these different PUSCH transmissions: The conditions include the same modulation mode, the same UL DAI value, and / or the same beta offset for the same UCI type.

[0089] In some implementations, when UCIs in a PUCCH transmission with repetition are multiplexed onto different PUSCH transmissions, these different PUSCH transmissions must satisfy all of the following conditions for better joint decoding between UCIs multiplexed onto these different PUSCH transmissions: The conditions include the same modulation mode, the same UL DAI value, and the same beta offset for the same UCI type.

[0090] In various implementations, the modulation, UL DAI, and / or beta offset may be indicated in the UL grants corresponding to these PUSCH transmissions.

[0091] In another non-limiting example shown in FIG. 10, a PUCCH transmission with a repetition factor of 4 starts at slot n+3, and its repetitions are in slots n+3, n+4, n+8, and n+9, respectively. A PUSCH1 transmission with a repetition factor of 2 starts at slot n+3, and its repetitions are in slots n+3 and n+4. A PUSCH2 transmission with no repetition factor is in slot n+8. A PUSCH3 transmission with no repetition factor is in slot n+9. In each slot in which each repetition of a PUCCH transmission is located, each repetition of the PUCCH transmission overlaps with one repetition of the PUSCH1 transmission, PUSCH2 transmission, or PUSCH3 transmission in the time domain. That is, each repetition of a PUCCH transmission overlaps with a PUSCH transmission in the time domain. Therefore, UCI in a PUCCH transmission is multiplexed with the PUSCH transmission that overlaps with the PUCCH transmission in each overlapping slot. That is, in slot n+3 and slot n+4, UCI in PUCCH transmission is multiplexed into two PUSCH1 repetitions of PUSCH1 transmission, respectively. In slot n+8, UCI in PUCCH transmission is multiplexed into PUSCH2 transmission. In slot n+9, UCI in PUCCH transmission is multiplexed into PUSCH3 transmission. PUCCH transmission is not transmitted in slot n+3, slot n+4, slot n+8, or slot n+9.

[0092] In some implementations, when UCI in a PUCCH transmission with repetition is multiplexed onto different PUSCH transmissions, these different PUSCH transmissions must satisfy at least one of the following conditions for better joint decoding between UCI multiplexed onto these different PUSCH transmissions: The conditions include the same modulation, the same UL DAI value, and / or the same beta offset for the same UCI type.

[0093] In some implementations, when UCI in a PUCCH transmission with repetition is multiplexed onto different PUSCH transmissions, these different PUSCH transmissions must satisfy at least two of the following conditions for better joint decoding between UCI multiplexed onto these different PUSCH transmissions: The conditions include the same modulation, the same UL DAI value, and / or the same beta offset for the same UCI type.

[0094] In some implementations, when UCI in a PUCCH transmission with repetition is multiplexed onto different PUSCH transmissions, these different PUSCH transmissions must satisfy all of the following conditions for better joint decoding between UCI multiplexed onto these different PUSCH transmissions: The conditions include the same modulation, the same UL DAI value, and the same beta offset for the same UCI type.

[0095] In various implementations, the modulation, UL DAI, and beta offset may be indicated in the UL grants corresponding to these PUSCH transmissions.

[0096] Various embodiments may provide conditions for performing UCI multiplexing in various situations. When the conditions as described in various embodiments / implementations are met, UCI multiplexing is performed and joint decoding between different UCI transmissions can still be performed.

[0097] In some implementations, a PUCCH transmission with repetitions overlaps with a PUSCH transmission in the time domain, and the conditions may include: Each repetition of a PUCCH transmission overlaps with a PUSCH transmission in the time domain; This includes multiple PUCCH repetitions of a PUCCH transmission each overlapping with different repetitions of the same PUSCH transmission in the time domain; This also includes each PUCCH repetition of a PUCCH transmission each overlapping with different PUSCH transmissions in the time domain; This also includes a combination of the above two situations. When a repetition of a PUCCH transmission overlaps with multiple PUSCH transmissions in the time domain, the multiple PUSCH transmissions need to satisfy at least one of the following conditions: the same modulation, the same UL DAI value, and the same beta offset value.

[0098] Embodiment Set II This disclosure describes various embodiments in which partial repetitions of a PUCCH transmission with repetitions overlap with one or more PUSCH transmissions, with or without a repetition factor in the time domain, and the remaining repetitions of the PUCCH transmission do not overlap with any PUSCH transmissions in the time domain. In some implementations, if the following conditions are met, UCI in a PUCCH transmission is multiplexed onto a PUSCH transmission in a slot in which the PUCCH transmission overlaps with a PUSCH transmission: The partial repetitions of the PUCCH transmission are not transmitted; The remaining repetitions of the PUCCH transmission are still transmitted.

[0099] In some implementations, a PUSCH transmission without a repetition factor means that the PUSCH transmission does not perform repetition transmission, and a PUSCH transmission with a repetition factor means that the PUSCH transmission performs repetition transmission.

[0100] In some implementations, if a PUCCH transmission with repetition and a PUSCH transmission satisfy the following conditions, UCI in a PUCCH transmission is multiplexed onto a PUSCH in an overlapping slot. A PUCCH transmission with repetition overlaps in the time domain with one or more PUSCH transmissions with or without repetition in some of the slots of the PUCCH transmission. That is, in some slots of the PUCCH transmission, the PUCCH transmission does not overlap with any PUSCH transmission in the time domain. In other slots of the PUCCH transmission, the PUCCH transmission overlaps with the PUSCH transmission in the time domain. Thus, in slots where the PUCCH transmission and the PUSCH transmission overlap, UCI in the PUCCH transmission is multiplexed onto the PUSCH transmission that overlaps with the PUCCH transmission, and the PUCCH transmission is not transmitted. In slots where the PUCCH transmission does not overlap with the PUSCH transmission, the PUCCH transmission is still transmitted. Therefore, UCI in a PUCCH transmission has two transmission modes: one is due to the PUCCH transmission and the other is due to the PUSCH transmission.

[0101] In some implementations, for better joint decoding between the two transmission modes, at least one of the following conditions is required for PUCCH and PUSCH transmissions: the UCI information in the PUCCH transmission exceeds two bits, the PUCCH and PUSCH transmissions use the same modulation, the UCI information in the PUCCH transmission is of a single UCI type (e.g., one of HARQ-ACK, CSI-1, and CSI-2), and / or the resource size used by the UCI in the PUCCH transmission is the same as that used by the UCI in the PUSCH transmission.

[0102] In some implementations, for better joint decoding between the two transmission modes, all of the following conditions are required for PUCCH and PUSCH transmissions: the UCI information in the PUCCH transmission exceeds two bits, the PUCCH and PUSCH transmissions use the same modulation, and the UCI information in the PUCCH transmission is of a single UCI type (e.g., one of HARQ-ACK, CSI-1, and CSI-2).

[0103] In some implementations, for better joint decoding between the two transmission modes, all of the following conditions are required for PUCCH and PUSCH transmissions: the UCI information in PUCCH transmission exceeds 2 bits, the PUCCH and PUSCH transmissions use the same modulation, the UCI information in PUCCH transmission is of a single UCI type (e.g., one of HARQ-ACK, CSI-1, and CSI-2), and the resource size used by UCI in PUCCH transmission is the same as that used by UCI in PUSCH transmission.

[0104] In some implementations, if there are multiple PUSCH transmissions, the multiple PUSCH transmissions must meet at least one of the following requirements: they have the same UL DAI value, they have the same modulation, and / or they have the same beta offset for the same UCI type.

[0105] For the non-limiting example shown in Figure 11, a PUCCH transmission with a repetition factor of 4 begins in slot n+3, with the remaining repetitions occurring in slot n+4, slot n+8, and slot n+9. In slot n+8, a PUSCH1 transmission with no repetition factor is transmitted. In slot n+9, a PUSCH2 transmission with no repetition factor is transmitted.

[0106] In some implementations, the UCI information in the PUCCH transmission is a HARQ-ACK with more than two bits. The PUCCH, PUSCH1, and PUSCH2 transmissions have the same modulation. The PUSCH1 and PUSCH2 transmissions are configured with the same UL DAI and beta offset values. In slot n+8 of the PUCCH transmission, the repetitions of the PUCCH transmission overlap with the PUSCH1 transmission in the time domain. In slot n+9 of the PUCCH transmission, the repetitions of the PUCCH transmission overlap with the PUSCH2 transmission in the time domain. In slot n+3 and slot n+4 of the PUCCH transmission, the PUCCH transmission does not overlap with any PUSCH in the time domain. That is, in the portion of the slot of the PUCCH transmission with the repetition factor, the PUCCH repetitions overlap with the PUSCH transmission in the time domain.

[0107] In some implementations, detailed operations may include: PUCCH transmissions are transmitted in slot n+3 and slot n+4; in slot n+8, HARQ-ACK in the PUCCH transmission is multiplexed onto PUSCH1 transmission; in slot n+9, HARQ-ACK in the PUCCH transmission is multiplexed onto PUSCH2 transmission; PUCCH transmissions are no longer transmitted in slot n+8 and slot n+9.

[0108] For another non-limiting example as shown in Figure 12, a PUCCH transmission with a repetition factor of 4 begins in slot n+3, with the remaining repetitions occurring in slot n+4, slot n+8, and slot n+9. A PUSCH transmission with a repetition factor of 2 is transmitted in slot n+8 and slot n+9.

[0109] In some implementations, the UCI information in the PUCCH transmission is a HARQ-ACK with more than two bits. The PUCCH transmission and the PUSCH transmission have the same modulation. In slot n+8 of the PUCCH transmission, the repetitions of the PUCCH transmission overlap with the PUSCH transmission in the time domain. In slot n+9 of the PUCCH transmission, the repetitions of the PUCCH transmission overlap with the PUSCH transmission in the time domain. In slots n+3 and n+4 of the PUCCH transmission, the PUCCH transmission does not overlap with any PUSCH in the time domain. That is, in the portion of the slot of the PUCCH transmission with the repetition factor, the PUCCH repetitions overlap with the PUSCH transmission in the time domain.

[0110] In some implementations, the detailed operation is that PUCCH transmissions are transmitted in slot n+3 and slot n+4. In slot n+8, the HARQ-ACK in the PUCCH transmission is multiplexed onto the PUSCH transmission. In slot n+9, the HARQ-ACK in the PUCCH transmission is multiplexed onto the PUSCH transmission. PUCCH transmissions are no longer transmitted in slot n+8 and slot n+9.

[0111] 11 and 12, in slots n+8 and n+9, the HARQ-ACK in the PUCCH transmission is multiplexed into the PUCCH transmission, and both the HARQ-ACK and the PUSCH transmission are ultimately transmitted. When using existing technology, the PUSCH transmission is dropped, and only the HARQ-ACK is transmitted in the PUCCH transmission.

[0112] In various embodiments, conditions for performing UCI multiplexing are provided for a specific case in which PUCCH transmission and PUSCH transmission overlap in the time domain. When these conditions are met, corresponding UCI multiplexing is performed, and UCI transmitted based on the PUCCH mode and PUSCH mode can still be jointly decoded. This specific case may include a case in which partial repetitions of a PUCCH transmission with repetitions overlap with one or more PUSCH transmissions in the time domain, with or without a repetition factor, within one or more slots, and the remaining repetitions of the PUCCH transmission do not overlap with any PUSCH transmissions in the time domain within another one or more slots. The given conditions may include a case in which the PUCCH transmission has the same modulation as the PUSCH transmission. The UCI in the PUCCH transmission is a single UCI type exceeding two bits. If there are multiple PUSCH transmissions, the multiple PUSCH transmissions have the same modulation (and the same beta offset).
