[0045] Fig. 1 illustrates an example of a communication environment 100 in which some example embodiments of the present disclosure may be implemented. The communication environment 100, which may be a part of a communication network, includes a terminal device 110 and a network device 120.
[0046] The communication environment 100 may include any suitable number of devices and cells. In the communication environment 100, the network device 120 may provide services to the terminal device 110, and the network device 120 and the terminal device 110 may communicate data and control information with each other. In some embodiments, the network device 120 and the terminal device 110 may communicate with direct links / channels.
[0047] In the communication environment 100, a link from the network device 120 to the terminal device 110 is referred to as a downlink (DL) , whereas a link from the terminal device 110 to the network device 120 is referred to as an uplink (UL) .

In uplink, the terminal device 110 is a transmitting TX device (or a transmitter) and the network device 120 is a RX device (or a receiver) . It is to be understood that the network device 120 may provide one or more serving cells. In some embodiments, the network device 120 may provide multiple cells.
[0048] It is to be understood that the particular number of various communication devices and the particular number of various communication links as shown in Fig. 1 is for illustration purpose only without suggesting any limitations. The communication environment 100 may include any suitable number of communication devices, any suitable number of communication links, and any suitable number of other elements adapted for implementing communications. In addition, it should be appreciated that there may be various wireless as well as wireline communications (if needed) among all of the communication devices.
[0049] Communications among devices in the communication environment 100 may be implemented according to any appropriate communication protocol (s) , including, but not limited to, cellular communication protocols of the third generation (3G) , the fourth generation (4G) and the fifth generation (5G) , the sixth generation (6G) , and on the like, wireless local network communication protocols such as Institute for Electrical and Electronics Engineers (IEEE) 802.11 and the like, and / or any other protocols currently known or to be developed in the future. Moreover, the communication may utilize any appropriate wireless communication technology, comprising but not limited to: Code Division Multiple Access (CDMA) , Frequency Division Multiple Access (FDMA) , Time Division Multiple Access (TDMA) , Frequency Division Duplex (FDD) , Time Division Duplex (TDD) , Multiple-Input Multiple-Output (MIMO) , Orthogonal Frequency Division Multiple (OFDM) , Discrete Fourier Transform spread OFDM (DFT-s-OFDM) and / or any other technologies currently known or to be developed in the future.
[0050] A terminal device 110 is generally configured to transmit UL control information (UCI) on a PUCCH. The UCL may include channel state information (CSI) , a scheduling request (SR) and Hybrid Automatic Repeat Request-Acknowledgement (HARQ-ACK) information. As a part of the data transmission, a payload of the terminal device 110 may be transmitted on a PUSCH, which may be transmitted in either a full slot or during a fraction of a slot.
[0051] When the terminal device 110 has both a PUCCH and a PUSCH that are expected to be transmitted in a same slot (that is, in an overlapping time resource) , the terminal device 110 may need to process normal PUSCH resources to be able to transmit the PUCCH along with the PUSCH transmission. Currently, a solution for handing the overlapping of PUSCH and PUCCH may be performed in a slot level. For example, when a device 110 transmits a PUSCH over one or more slots or multiple PUSCHs over one or more slots that are scheduled by a DCI format, and the device 110 transmits a PUCCH with HARQ-ACK and / or CSI information over a single slot that overlaps with the PUSCH transmission in the one or more slots, and the PUSCH transmission in the one or more slots fulfills the conditions for multiplexing the HARQ-ACK and / or CSI information, the terminal device 110 may multiplex the HARQ-ACK and / or CSI information in the PUSCH transmission in the one or more slots. The terminal device 110 may not multiplex HARQ-ACK and / or CSI information in the PUSCH transmission in a slot from the one or more slots if the terminal device 110 does not transmit a single-slot PUCCH with HARQ-ACK and / or CSI information in the slot in case the PUSCH transmission was absent.
[0052] Fig. 2 illustrates a principle of performing simultaneous transmission of PUCCH and PUSCH within the same slot. As shown in Fig. 2, UCI multiplexing in a PUSCH occurs at a bit level, and the UCI codeword (s) and UL-SCH codeword are concatenated to form a single codeword to transmit on the PUSCH.
[0053] A collision handling between PUCCH and PUSCH transmissions has been studied and provided. Specifically, for a case of PUCCH repetitions overlapping in time with PUSCH repetitions, PUCCH repetitions are to be transmitted, while the overlapping PUSCH repetitions are to be dropped. Other non-overlapping PUSCH repetitions (if any) are still to be transmitted.
[0054] For example, when a terminal device 110 transmits a PUCCH over a first number of slots and the terminal device 110 may transmit a PUSCH with repetition Type A or with TB processing over multiple slots over a second number of slots, and the PUCCH transmission may overlap with the PUSCH transmission in one or more slots, and the conditions for multiplexing the UCI in the PUSCH are satisfied in the overlapping slots, the terminal device 110 may transmit the PUCCH and does not transmit the PUSCH in the overlapping slots.
[0055] Fig. 3 illustrates a solution of handling PUCCH repetitions overlapping in time with PUSCH repetitions according to a solution. In Fig. 3, 2 PUCCH repetitions (PUCCH rep #1 and PUCCH rep #2) are transmitted over slots #1 and #2, respectively. A PUSCH transmission including PUSCH repetitions, PUSCH rep #1~PUSCH rep #4, occurs over slots #0~#4. As shown in Fig. 3, 2 PUCCH repetitions (PUCCH rep #1 and PUCCH rep #2, as shown in Fig. 3) overlap in time with 2 PUSCH repetitions (PUSCH rep #2 and PUSCH rep #3) at slots #1 and #2. According to a solution, the terminal device may drop the overlapped PUSCH repetitions #2 and #3, while transmit the non-overlapped PUSCH repetitions #1 and #4 over slot #0 and #3, respectively. The terminal device may transmit the PUCCH repetitions, PUCCH rep #1 and PUCCH rep #2 over slot #1 and #2, respectively. In Fig. 3, the PUSCH rep #2 and PUSCH rep #3 are shown in dashed lines, indicating these two PUSCH repetitions are dropped by the terminal device.
[0056] In some cases, orthogonal cover codes (OCC) is used to enhance the capacity and / or throughput of a cellular network. OCC is a coding scheme that generates a set of orthogonal codes. For example, a set of orthogonal codes (e.g. Walsh-Hadamard codes) having ideal zero cross-correlation may be generated and different codes may be assigned to different terminal devices to achieve orthogonal (i.e., no interference) UL transmissions on the same time-frequency resources. By employing OCC, multiple terminal devices may be enabled to multiplex in a same time-frequency resource.
[0057] Fig. 4 illustrates a schematic diagram 400 for illustrating a principle of OCC. Fig. 4 is shown with an example of two terminal devices (e.g., a first terminal device and a second terminal device) transmitting 2 PUSCH repetitions in the same time-frequency resources. For the transmissions, the two terminal devices respectively apply different OCCs to their transmission signals, allowing a network device to receive (i.e., demodulate and decode) the transmission signals of each terminal device without interference of the other terminal device.
[0058] It is assumed that there is no channel impairment or additive noise, for purposes of simplicity of description. It is also assumed that x1 and x2 represent the signals transmitted by the first terminal device and the second terminal device, respectively, and signals represented by x1 and x2 are both in repetitions. Signals represented by y1 and y2 are the signals received by the network device in a first repetition and in a second repetition, respectively. It is to be noted that in this example, the first terminal device is applied with the OCC [1, 1] and the second terminal device is applied with the OCC [1, -1] . As shown by equation (1) , the network device may retrieve the transmission a signal of the second terminal device without any interference from the first terminal device by cross-correlating the two received transmission signals y1 and y2 with the OCC used by the second terminal device (i.e., [1, -1] ) .
[0059] The above example is only for the purposes of illustration and uses Walsh-Hadamard orthogonal codes as an OCC set. Those skilled in the art may understand that different sequences may be used to realize orthogonality among terminal devices without impacting the applicability of the present disclosure. In addition, in order to multiplex terminal devices with a number of N, a number of at least N PUSCH (or signal) repetitions are necessary.
[0060] It is assumed that the terminal device 110 performs transmission during a full slot due to the normal expected use case of the terminal device 110 being in coverage shortage for being able to utilize OCC on top of the PUSCH transmissions.
[0061] In current 3GPP specifications, a collision or an overlapping handling between PUSCH and PUCCH with UCI is in a slot level. For example, when a PUCCH transmission is overlapped with a PUSCH transmission in one slot, the collision handling only has impact on the PUCCH / PUSCH transmission of the overlapping slot without any impact on the PUCCH / PUSCH transmissions of other slots. Thus, dropping some PUSCH repetitions may barely have severe impact on other repetitions, e.g., in terms of PUSCH repetition Type A or Type B.
[0062] As OCC is to be used to enhance the capacity and / or throughput of a cellular network, handling solutions of PUCCH overlapping with any PUSCH repetitions within an OCC group has been raised. For example, three options have been raised in RAN1#119 meeting for UCI multiplexing for NR-OCC topic, including UCI multiplexing, UCI drop and PUSCH repetitions drop.
[0063] For example, for PUCCH without repetition overlaps with inter-slot OCC with any PUSCH repetitions in an OCC group, the first option is to drop UCI, the second option is to transmit UCI on PUCCH and drop all PUSCH repetitions within an OCC group (or an OCC period) , and the third option is to multiple UCI on a PUSCH with inter-slot OCC. For example, UCI may be multiplexed on all PUSCH repetitions within an OCC group with inter-slot OCC. Alternatively, UCI may be multiplexed on PUSCH and OCC is not applied within the OCC group. Alternatively, UCI may be multiplexed on PUSCH and OCC is not applied within the PUSCH repetitions.
[0064] Herein, an OCC group means all the PUSCH repetitions within an OCC period, that is, covered by an OCC code. A previous OCC period means one or more OCC periods before a current OCC period. A next OCC period means one or more OCC periods after a current OCC period.
[0065] In some cases, when OCC is enabled for transmissions of PUSCH repetitions, to guarantee the OCC orthogonality, it’s essential that contents of all the PUSCH repetitions within an OCC period are the same. Accordingly, a collision handling between a PUCCH and a PUSCH repetition of any slot within an OCC period may also have impact on transmissions of other PUSCH repetitions.
[0066] For example, if a PUCCH needs to be multiplexed on a PUSCH repetition, then the PUCCH may also need to be multiplexed and spread in all the other PUSCH repetitions within an OCC period so that OCC orthogonality can be maintained. Those skilled in the art may understand that one PUSCH repetition (e.g., with a length of 8) may be applied with a OCC group having a length shorter than the length of a PUSCH repetition. For example, an OCC group may have a duration for 2 or 4 slots. Hence there may be multiple OCC groups that each may be seen as a separate transmission instance (at least from orthogonality point of view) .
[0067] For PUSCH repetitions with OCC, there may also be multiple PUCCHs with UCIs occurring in multiple slots within an OCC period. Fig. 5 illustrates a scenario in which both PUCCH without repetitions and PUCCH with repetitions overlap with PUSCH repetitions within an OCC period. In the scenario of Fig. 5, a problem occurs when there are both PUCCH without repetitions and PUCCH with repetitions within an OCC period. As shown in Fig. 5, an OCC period (for example, kth OCC period among multiple OCC periods) includes 4 time slots, slot n, slot (n+1) , slot (n+2) , and slot (n+3) . PUCCH may transmit UCI-1 502 over slot n, and transmit UCI-2 504 over slot (n+2) and UCI-2 506 over slot (n+3) . UCI-1 502 is a HARQ-ACK, and UCI-2 504 and UCI-2 506 are CSI with repetitions.
[0068] In Fig. 5, multiple PUSCH repetitions are transmitted within the kth OCC period. A PUSCH repetition 512 overlaps with the UCI-1 502 at slot n, and the PUSCH repetitions 516 and 518 overlap with the UCI-2 repetitions 504 and 506 at slot (n+2) and slot (n+3) , respectively. In this scenario as shown in Fig. 5, according to a collision handling solution, UCI-1 502 is to be multiplexed on these PUSCH repetitions 512, 514, 516, and 518 within the OCC period, while all the PUSCH repetitions 512, 514, 516, and 518 within the OCC period is to be dropped due to UCI-2 repetitions overlap with PUSCH repetitions 516 and 518. Then for the terminal device 110, there may be a conflict or a contradiction with respect on how to handle these PUSCH transmissions.
[0069] Fig. 6 illustrates another scenario with a HARQ-ACK deferred from a previous OCC period and PUCCH with repetitions occur within a current OCC period. In the scenario of Fig. 6, a problem occurs when a UCI with a relatively high priority is deferred from a previous OCC period.
[0070] As shown in Fig. 6, there are two OCC periods: kth OCC period and (k+1) th OCC period. Multiple PUSCH repetitions 612, 614, 616, and 618 are transmitted within the kth OCC period, and multiple PUSCH repetitions 622, 624, 626, and 628 are transmitted within the (k+1) th OCC period. UCI-1 602 is a HARQ-ACK without repetition and is deferred from the OCC period. UCI-2 repetitions 604 and 606 are PUCCH repetitions and overlap with PUSCH repetitions 622 and 624 at slot (n+4) and slot (n+5) , respectively. UCI-2 repetitions 604 and 606 are PUCCH repetitions occurs in the (k+1) th OCC period. That is, UCI-1 602 deferred from a previous OCC period of the (k+1) th OCC period and UCIs-2 604 and 606 are present in the (k+1) th OCC period.
[0071] UCI-1 602 has a higher priority (e.g., a UCI type priority) than that of any of UCI-2 604 and UCI-2 606. Based on current collision handling solutions, UCI-1 602 is to be multiplexed on the PUSCH transmission 622, 624, 626, and 628 within the (k+1) th OCC period, while due to a collision between UCIs-2 and PUSCH repetitions, all the PUSCH transmissions 622, 624, 626, and 628 within the (k+1) th OCC period is to be dropped. Then, for the terminal device 110, there may also be a conflict or a contradiction with respect to how to handle these PUSCH transmissions.
[0072] Currently, a collision between PUCCH and PUSCH may not be resolved based on existing solutions. Accordingly, it is desired to develop a mechanism for handling a collision or an overlapping between PUCCH and PUSCH, e.g., at an OCC period level.
[0073] As used herein, the term “OCC period” may indicate a time duration in which a terminal device may transmit PUSCH repetitions that are subject to an orthogonal cover code (OCC) . Alternative terms for “OCC period” may be “OCC group” or “PUSCH OCC group” . Herein, an OCC group means all the PUSCH repetitions within an OCC period, that is, covered by an OCC code. The term “OCC period” may be exchanged with the term “OCC group” herein.
[0074] Fig. 7 illustrates an example signaling process in accordance with some embodiments of the present disclosure. For the purpose of discussion, the process 700 will be described with reference to Fig. 1. The process 700 may involve a terminal device 110. The process 700 may further involve a network device 120. It would be appreciated that although the process flow 700 has been described in the communication environment 100 of Fig. 1, this process flow may be likewise applied to other communication scenarios. Furthermore, in the signaling process 700, it is possible to add, omit, modify one or more operations, or the operations may also be performed in any suitable order without departing from the scope of the present disclosure.
[0075] In the process 700, the terminal device 110 may determine (702) whether one or more Physical Uplink Shared Channel (PUSCH) repetitions within an Orthogonal Cover Code (OCC) period are to be dropped with respect to a Physical Uplink Control Channel (PUCCH) transmission that overlaps with the one or more PUSCH repetitions based on intra-slot overlapping handling rule.
[0076] In some embodiments, within an OCC period, there may be multiple time slots, e.g., 4 time slots as shown in either Fig. 5 or Fig. 6. In the OCC period, multiple PUSCH repetitions are corresponding to the multiple time slots. When a PUCCH transmission overlaps with the one or more PUSCH repetitions, the terminal device 110 may determine, based on intra-slot overlapping rule, whether the one or more PUSCH repetitions need to be dropped. In some embodiments, the intra-slot overlapping rule includes any solution (for example, an existing solution) for handling overlapping of PUSCH and PUCCH.
[0077] For example, taking the scenario shown in Fig. 3 for example. In an OCC period, two PUSCH repetitions #2 and #3 are overlapping with two PUCCH repetitions #1 and #2. Based on the intra-slot overlapping rule, the terminal device 110 may determine that the PUSCH repetitions #2 and #3 need to be dropped at slot #1 and slot #2, respectively.
[0078] In some embodiment, the terminal device 110 may determine, at 702, whether a PUSCH repetition within an OCC period is to be dropped with respect to a PUCCH transmission that overlaps with the PUSCH repetition based on an intra-slot overlapping handling rule. That is, a determination made for a PUSCH repetition at a time slot may not impact on anther PUSCH repetition over another time slot.
[0079] The terminal device 110 may, based on a determination that none of the one or more PUSCH repetitions is to be dropped, determine (704) , based on an OCC period level overlapping handling rule, whether to perform PUSCH dropping within the OCC period.
[0080] In some embodiment, the terminal device 110 may determine whether the PUSCH dropping is to be performed, at 704, based on an OCC period level overlapping handling rule. In some embodiments, when the PUSCH dropping is determined to be performed, multiple PUSCH repetitions (e.g., all the PUSCH repetitions) within the OCC period may be dropped. For example, for the scenario as shown in Fig. 3, if the terminal device 110 determines to perform PUSCH dropping at 704, all the PUSCH repetitions #1, #2, #3, and #4 may be dropped, accordingly.
[0081] In some embodiments, the network device 120 may determine (712) whether one or more PUSCH repetitions within an OCC period are to be dropped with respect to a PUCCH transmission that overlaps with the one or more PUSCH repetitions based on intra-slot overlapping handling rule. Based on a determination that none of the one or more PUSCH repetitions is to be dropped, the network device 120 may determine (714) , based on an OCC period level overlapping handling rule, whether PUSCH dropping to be performed within the OCC period. Detailed operations for 712 and 714 are similar for the operations at 702 and 704, thus, repetitive descriptions are omitted here for the purposes of clarity and brevity.
[0082] The terminal device 110 may transmit (706) a PUCCH or PUSCH transmission to the network device 120. In some embodiments, when the terminal device 110 determines not to perform PUSCH dropping, PUSCH transmission may be performed. Then the terminal device 110 may transmit multiple PUSCH repetitions (e.g., all of the PUSCH repetitions within the OCC period) to the network device 120. In some embodiments, the transmitted PUSCH repetitions may be multiplexed with UCI (s) .
[0083] Advantageously, embodiments of the present disclosure provide enhancements for PUSHC and PUCCH overlapping via OCC.
[0084] Fig. 8 illustrates a flowchart of a process performed by the terminal device 110 for determining whether to perform PUSCH dropping according to embodiments of the present disclosure. The process may start from block 810, in which the terminal device 110 may determine whether at least one PUSCH repetition to be dropped according to a slot level PUCCH and PUSCH collision handling rule. In some embodiments, a slot level PUCCH and PUSCH collision handling rule may include an intra-slot overlapping handling rule (for example, as mentioned in 3GPP Technical Specification 38.213) that may be applied when a PUSCH overlaps with a PUCCH. In some embodiments, the terminal device 110 may determine whether one or more PUSCH repetitions within an OCC period are to be dropped with respect to a PUCCH transmission that overlaps with the one or more PUSCH repetitions based on intra-slot overlapping handling rule. The operation at 810 is similar to that performed at 702 in Fig. 7, and repetitive description is omitted herein for the purposes of clarity and brevity.
[0085] When the terminal device 110 determines that there is one or more PUSCH repetition to be dropped at 810, the process 800 may proceed to block 830, in which the terminal device 110 may drop all the PUSCH repetitions within the OCC period. Accordingly, the PUCCHs within the OCC period are transmitted.
[0086] When the terminal device 110 determines that there is no PUSCH repetition to be dropped at 810, the process 800 proceeds to block 820, in which the terminal device 110 may determine whether to perform the PUSCH dropping based on across-slots PUCCH and PUSCH collision handling rule. The across-slots PUCCH and PUSCH collision handling rule may be applied when a PUSCH repetition overlaps with a PUCCH within an OCC period, and an operation performed on one PUSCH repetition may also be applied to another PUSCH repetition within the OCC period. In some embodiments, the across-slots PUCCH and PUSCH collision handling rule may also be referred as OCC period level overlapping handling rule. In some embodiments, at 820, the terminal device 110 may further determine whether to perform PUSCH dropping within the OCC period based on an OCC period level overlapping handling rule.
[0087] In some embodiments, the terminal device 110 may determine whether to perform PUSCH dropping within the OCC period based on a subset of UCIs within the OCC period. Specifically, the terminal device 110 may determine or select a subset of UCIs within the OCC period. In some embodiments, the UCIs in the subset are allowed to be multiplexed on a PUSCH repetition over a time slot with respect to an associated PUCCH transmission that overlaps with the PUSCH repetition.
[0088] Fig. 9 illustrates an example of a subset of UCIs within an OCC period according to embodiments of the present disclosure. As shown in Fig. 9, within the OCC period including time slots m, m+1, m+2 and m+3, there are 3 UCIs. There are three UCIs occurring in the current OCC period: the first UCI 902 which is HARQ-ACK, the second UCI 904 which is CSI, and the third UCI which is SR. According to a possible rule (for example, an existing rule) , the first UCI 902 may be allowed to be multiplexed on a PUSCH repetition 912 corresponding to a time slot m associated with the UCI 902, and the second UCI 904 is allowed to be multiplexed on a PUSCH repetition 916 corresponding to a time slot m+2 associated with the UCI 904. The third UCI 906 is not allowed to be multiplexed on a PUSCH repetition 918 corresponding to a time slot m+3 associated with the UCI 906. The terminal device 110 may determine a subset 920 of UCIs including the UCI 902 and UCI 904. In some embodiments, an UCI in the subset is allowed to be multiplexed on a PUSCH repetition corresponding to a time slot associated with the UCI. In some embodiments, a single UCI in the subset is allowed to be multiplexed on a PUSCH repetition corresponding to a time slot associated with the UCI. In some embodiments, all the UCIs in the subset are allowed to be multiplexed on a PUSCH repetition corresponding to a time slot associated with the UCI.
[0089] In some embodiments, the terminal device 110 may determine whether a first UCI is present in the subset, and the first UCI is a UCI that is not allowed to be transmitted by being multiplexed on multiple PUSCH repetitions within the OCC period and is not allowed to be deferred to a next OCC period.
[0090] Referring back to Fig. 9, when a PUSCH repetition is not allowed to support multiple UCIs from different time slots, the terminal device 110 may determine that the multiple UCIs may not be transmitted by being multiplexed on multiple PUSCH repetitions. For example, if a PUSCH repetition 912, 914, 916, or 918 cannot support the UCI-1 and UCI-2 in time slots m and m+2, respectively, the terminal device may determine that the UCI-1 and UCI-2 may not be transmitted by being multiplexed on multiple PUSCH repetitions.
[0091] In some embodiments, a PUSCH may support a combination of HARQ-ACK of one slot and CSI of another slot, but cannot support other combinations of different types of UCIs. Then the terminal device 110 may determine that the UCIs with a combination other than HARQ-ACK and CSI may not be transmitted by being multiplexed on multiple PUSCH repetitions.
[0092] In some embodiments, based on a determination that the first UCI is present in the subset, the terminal device 110 may determine at 820 that the PUSCH dropping is to be performed. The process 800 may proceed to block 830, in which the terminal device 110 may drop a plurality of PUSCH repetitions (for example, all of the PUSCH repetitions) within the OCC period. In some embodiments, at 830, if a UCI deferred from the previous OCC period is present in the OCC period, the terminal device 110 may also drop the deferred UCI(s) when performing the PUSCH dropping.
[0093] In some embodiments, based on a determination that the first UCI is absent from the subset, the terminal device 110 may determine at 820 that the PUSCH dropping is not to be performed. The process 800 may proceed to block 840, in which the terminal device 110 may perform PUSCH transmission and UCI multiplexing (if any) . For example, the terminal device 110 may transmit multiple PUSCH repetitions (for example, all of the PUSCH repetitions) within the OCC period with one or more UCIs in the subset being multiplexed. For example, one or more UCIs in the subset may be multiplexed on the transmitted multiple PUSCH repetitions.
[0094] In some embodiments, at 840, when transmitting the multiple PUSCH repetitions, the terminal device 110 may transmit PUSCH repetitions with a part of UCIs in the subset being multiplexed, and the terminal device may defer a remaining part of the UCIs in the subset to a next OCC period. For example, assuming there are two UCIs in the subset, the terminal device 110 may transmit PUSCH repetitions with one UCI being multiplexed, and defer the other UCI to the next OCC period.
[0095] In some embodiments, at 840, based on a determination that there is no UCI is to be multiplexed, the terminal device 110 may perform PUSCH transmission by transmitting PUSCH repetitions. The terminal device 110 may defer one or more UCI to a next OCC period (s) if there is any UCI (s) .
[0096] Fig. 10 illustrates a flowchart of another process performed by the terminal device 110 for determining whether to perform PUSCH dropping according to embodiments of the present disclosure. The procedures 1010, 1020, 1030, and 1040 are similar to procedures 810, 820, 830, and 840 as shown in Fig. 8. A difference in Fig. 10 is that a procedure 1050 is performed by the terminal device 110 before performing procedure 1010.
[0097] In some embodiments, the terminal device 110 may determine, at 1050, whether PUSCH dropping is allowed based on one or more UCIs deferred from one or more previous OCC periods. For example, the terminal device 110 may determine whether the PUSCH dropping is allowed with respect to a second UCI that is deferred from a previous OCC period. Based on a determination that the PUSCH dropping is not allowed, the process 1000 may proceed to the block 1040, in which the terminal device 110 may multiplex the second UCI deferred from the previous OCC period on a PUSCH repetition. The terminal device 110 may further transmit multiple PUSCH repetitions each with the multiplexed second UCI to the network device 120.
[0098] The terminal device 110 may determine, at 1050, whether the PUSCH dropping is allowed with respect to a second UCI that is deferred from a previous OCC period. In some embodiments, the terminal device 110 may compare a priority of the second UCI with a priority of a third UCI occurs within the OCC period, and the terminal device 110 may determine that the PUSCH dropping is not allowed based on determining that the priority of the second UCI is equal to or higher than the priority of the third UCI. In some embodiments, the third UCI is a UCI that has the highest priority among one or more of the UCIs that occur within the OCC period.
[0099] For example, assuming there are two UCIs deferred from the previous OCC period: UCI-11 and UCI-12, and there are three UCIs occurring in the current OCC period: UCI-21, UCI-22, and UCI-23. Among the UCI-21, UCI-22, and UCI-23, UCI-23 has the highest priority. The terminal device may compare a priority of the UCI-11 with the priority of the UCI-23 that has the highest priority among the UCIs occurring the OCC period, and compare a priority of the UCI-12 with that of the UCI-23. If any of the comparison indicates a priority of a deferred UCI is equal to or higher than the priority of the UCI-23, the terminal device 110 may determine that the PUSCH dropping is not allowed. For example, if the priority of the UCI-11 is equal to the priority of the priority of the UCI-23, the terminal device 110 may determine that the PUSCH dropping is not allowed.
[0100] In some alternative embodiments, the terminal device 110 may compare a priority of the second UCI which is deferred from the previous OCC period with a priority of a fourth UCI occurs within the OCC period, and the terminal device 110 may determine that the PUSCH dropping is not allowed based on determining that the priority of the second UCI is higher than the priority of the fourth UCI. In some embodiments, the fourth UCI is a UCI that has the highest priority among one or more of the UCIs that occur within the OCC period.
[0101] For example, assuming there are two UCIs deferred from the previous OCC period: UCI-11 and UCI-12, and there are three UCIs occurring in the current OCC period: UCI-21, UCI-22, and UCI-23. Among the UCI-21, UCI-22, and UCI-23, UCI-22 has the highest priority. The terminal device may compare a priority of the UCI-11 with the priority of the UCI-22 that has the highest priority among the UCIs occurring the OCC period, and compare a priority of the UCI-12 with that of the UCI-22. If any of the comparison indicates a priority of a deferred UCI is higher than the priority of the UCI-22, the terminal device 110 may determine that the PUSCH dropping is not allowed. For example, if the priority of the UCI-11 is higher than the priority of the priority of the UCI-22, the terminal device 110 may determine that the PUSCH dropping is not allowed.
[0102] Fig. 11 illustrate a scenario with a HARQ-ACK deferred from a previous OCC period and PUCCH with repetitions occur within a current OCC period. According the embodiments as described above, because the priority of the UCI 1102 is higher than any of the UCI 1104 and UCI 1106, the terminal device 110 may determine that the PUSCH dropping is not allowed. Then the terminal device 110 may perform PUSCH transmission by multiplexing the UCI 1102 deferred from the previous OCC period on a PUSCH 1122, PUSCH 1124, PUSCH 1126, and PUSCH 1128, and transmit the PUSCH repetitions multiplexed with the UCI 1102.
[0103] In alternative embodiments, the terminal device 110 may determine a type of the second UCI. Based on determining that the type of the second UCI is a predetermined type, the terminal device 110 may determine that the PUSCH dropping is not allowed. In some embodiments, the predetermined type includes a Hybrid Automatic Repeat Request-Acknowledgement (HARQ-ACK) .
[0104] Referring to Fig. 11, according the embodiments as described above, because the type of the deferred UCI 1102 is a predetermined type, which is HARQ-ACK, the terminal device 110 may determine that the PUSCH dropping is not allowed. Then the terminal device 110 may perform PUSCH transmission by multiplexing the UCI 1102 deferred from the previous OCC period on a PUSCH 1122, PUSCH 1124, PUSCH 1126, and PUSCH 1128, and transmit the PUSCH repetitions multiplexed with the UCI 1102.
[0105] Advantageously, by not allowing the PUSCH for a deferred UCI with a relatively high priority or with a predetermined type, these UCIs may be transmitted to the network device 120 by being multiplexed on PUSCH repetitions for transmission.
[0106] Based on a determination that the PUSCH dropping is allowed, the process 1000 may proceed to the block 1010, in which the terminal device 110 may determine whether the at least one PUSCH repetition is to be dropped with respect to the PUCCH transmission that overlaps with the at least one PUSCH repetition based on the intra-slot overlapping handling rule. The UCI in procedures 1010, 1030, and 1040 may further including the UCI (s) that is deferred from the previous OCC period. The procedures performed at 1010, 1030, and 1040 are similar as those described for procedures 810, 82, 830, and 840, and for the purposes for brevity, repetitive descriptions are omitted here.
[0107] In some embodiments, the terminal device 110, when determines that the PUSHC dropping is to be performed at 1010 or 1020, the process 1000 may proceed to the procedure 1030, in which the terminal device may perform the PUSCH dropping. In some embodiments, the terminal device 110 may drop a plurality of PUSCH repetitions (e.g., all of the PUSCH repetitions) within the OCC period as well as dropping one or more UCIs (e.g., the second UCI) which are deferred from the previous OCC period.
[0108] In some embodiments, when the terminal device 110 determines not to perform the PUSCH dropping, then PUSCH transmission may be performed at 1040. At 1040, the terminal device may transmit multiple PUSCH repetitions (for example, all of the PUSCH repetitions) within the OCC period with one or more UCIs in the subset being multiplexed. For example, one or more UCIs in the subset may be multiplexed on the transmitted multiple PUSCH repetitions. In some embodiments, at 1040, when transmitting the multiple PUSCH repetitions, the terminal device 110 may transmit PUSCH repetitions with a part of UCIs in the subset being multiplexed, and the terminal device may defer a remaining part of the UCIs in the subset to a next OCC period. For example, assuming there are three UCIs in the subset, the terminal device 110 may transmit PUSCH repetitions with one UCI being multiplexed, and defer the other two UCIs to the next OCC period. In some embodiments, at 1040, based on a determination that there is no UCI is to be multiplexed, the terminal device 110 may perform PUSCH transmission by transmitting PUSCH repetitions. The terminal device 110 may defer one or more UCI to a next OCC period (s) if there is any UCI (s) .
[0109] Fig. 12 illustrates an example signaling process 1200 in accordance with some embodiments of the present disclosure. Fig. 12 may be described with reference to Fig. 11 for illustration.
[0110] In the process 1200, the network device 120 may configure the terminal device 1100 with a PUCCH that carries an UCI, for example, CSI, at 1201. In the example of Fig. 12, the network device 120 may configure two UCI repetitions for (k+1) th OCC period, as shown in Fig. 11.
[0111] The network device 120 may configure the terminal device 110 with OCC operation at 1202. For example, the OCC length is 4, and HARQ-ACK deferring is supported. The network device 120 may grant scheduling for PUSCH repetitions with OCC at 1203. That is, the terminal device 120 is scheduled to transmit PUSCH repetitions with OCC with an OCC length of 4.
[0112] The network device 120 may grant scheduling for PDSCH-1 at 1204. That is, the terminal device 110 is scheduled to receive PDSCH-1 and feedback HARQ-ACK.
[0113] At 1205, the terminal device 110 may determine a transmission of PUCCHs (UCIs) / PUSCH when they collide in time within an OCC period. For example, at 1205, for the Kth OCC period, the terminal device 110 may determine that the PUSCH transmission is to be performed and a UCI, e.g., HARQ-ACK is to be deferred to the next OCC period, for example, by implementing the procedures at 810 or 810 and 820 as shown in Fig. 8. The terminal device 110 may transmit PUSCH repetitions (for example, PUSCH repetitions 1112, 1114, 1116, and 1118 in the Kth OCC period the as shown in Fig. 11) to the network device 120 at 1206. UCI 1102, which is a HARQ-ACK is to be deferred to the next OCC period.
[0114] At 1207, the terminal device 110 may determine a transmission of PUCCHs (UCIs) / PUSCH when they are colliding in time within an OCC period. At 1207, HARQ-ACK is to be multiplexed in all the four PUSCH repetitions within the OCC period K+1. For example, at 1207, for the (K+1) th OCC period as shown in Fig. 11, the terminal device 110 may determine that an UCI is deferred from the previous OCC period and PUSCH dropping is not allowed. For example, the terminal device 110 may determine that the PUSCH dropping is not allowed by implementing the procedure 1050 in Fig. 10. The terminal device 110 may perform PUSCH transmission with the deferred UCI being multiplexed on the PUSCH repetitions within the (K+1) th OCC period. The terminal device 110 may perform PUSCH transmission by multiplexing the UCI 1102 deferred from the previous OCC period on a PUSCH 1122, PUSCH 1124, PUSCH 1126, and PUSCH 1128, and transmit the PUSCH repetitions multiplexed with the UCI 1102. The UCIs 1104 and 1106 may not be multiplexed on the PUSCH repetitions and may be dropped.
[0115] It should be noted that, the example signaling process 1200 shown in Fig. 12 is only for the purposes of illustration. Different example signaling processes may be adopted according to practical requirements of the communication system.
[0116] Fig. 13 illustrates a flowchart of a method 1300 implemented at a terminal device in accordance with some example embodiments of the present disclosure. For the purpose of discussion, the method 1300 will be described from the perspective of the terminal device 110 with reference to Fig. 1.
[0117] At 1310, the terminal device 110 may determine whether at least one Physical Uplink Shared Channel (PUSCH) repetition within an Orthogonal Cover Code (OCC) period is to be dropped with respect to a Physical Uplink Control Channel (PUCCH) transmission that overlaps with the at least one PUSCH repetition based on an intra-slot overlapping handling rule. At 1320, based on a determination that none of the at least one PUSCH repetition is to be dropped, the terminal device 110 may determine, based on an OCC period level overlapping handling rule, whether to perform PUSCH dropping within the OCC period.
[0118] In some embodiments, the terminal device may be caused to determine whether to perform the PUSCH dropping within the OCC period by determining a subset of uplink control information, UCIs, wherein an UCI in the subset is allowed to be multiplexed on a PUSCH repetition corresponding to a time slot associated with the UCI; and determining whether a first UCI is present in the subset, wherein the first UCI is a UCI that is not allowed to be transmitted by being multiplexed on a plurality of PUSCH repetitions within the OCC period and is not allowed to be deferred to a next OCC period.
[0119] In some embodiments, based on a determination that the first UCI is present in the subset, the terminal device may determine that the PUSCH dropping within the OCC period is to be performed.
[0120] In some embodiments, the terminal device may perform the PUSCH dropping within the OCC period by dropping a plurality of PUSCH repetitions within the OCC period.
[0121] In some embodiments, based on a determination that the first UCI is absent from the subset, the terminal device may determine that the PUSCH dropping within the OCC period is not to be performed.
[0122] In some embodiments, the terminal device may transmit a plurality of PUSCH repetitions within the OCC period with at least one UCI in the subset being multiplexed.
[0123] In some embodiments, the terminal device may be caused to transmit a plurality of PUSCH repetitions within the OCC period with at least one UCI in the subset being multiplexed by: transmitting the plurality of PUSCH repetitions with a part of UCIs in the subset being multiplexed; and deferring a remaining part of the UCIs in the subset to a next OCC period.
[0124] In some embodiments, the terminal device may be caused to determine whether the at least one PUSCH repetition is to be dropped with respect to the PUCCH transmission that overlaps with the at least one PUSCH repetition by: determining whether the PUSCH dropping is allowed with respect to a second UCI that is deferred from a previous OCC period; and based on determining that the PUSCH dropping is allowed, determining whether the at least one PUSCH repetition is to be dropped with respect to the PUCCH transmission that overlaps with the at least one PUSCH repetition based on the intra-slot overlapping handling rule.
[0125] In some embodiments, the terminal device may be caused to determine whether the PUSCH dropping is allowed with respect to the second UCI that is deferred from the previous OCC period by: comparing a priority of the second UCI with a priority of a third UCI that occurs within the OCC period; and based on determining that the priority of the second UCI is equal to or higher than the priority of the third UCI, determining that the PUSCH dropping is not allowed.
[0126] In some embodiments, the third UCI is a UCI that has the highest priority among at least one of the UCI that occurs within the OCC period.
[0127] In some embodiments, the terminal device may be caused to determine whether the PUSCH dropping is allowed with respect to the second UCI that is deferred from the previous OCC period by: comparing a priority of the second UCI with a priority of a fourth UCI that occurs within the OCC period; and based on determining that the priority of the second UCI is higher than the priority of the fourth UCI, determining that PUSCH dropping is not allowed.
[0128] In some embodiments, the fourth UCI is a UCI that has the highest priority among at least one of the UCI that occurs within the OCC period.
[0129] In some embodiments, the terminal device may be caused to determine whether the PUSCH dropping is allowed with respect to the second UCI that is deferred from the previous OCC period by: determining a type of the second UCI; and based on determining that the type of the second UCI is a predetermined type, determining that the PUSCH dropping is not allowed.
[0130] In some embodiments, the predetermined type comprises a Hybrid Automatic Repeat Request-Acknowledgement, HARQ-ACK.
[0131] In some embodiments, based on determining that the PUSCH dropping is not allowed, the terminal device may perform PUSCH transmission.
[0132] In some embodiments, the terminal device is caused to perform the PUSCH transmission by: multiplexing the second UCI on a PUSCH repetition within the OCC period; and transmitting PUSCH repetitions within the OCC period multiplexed with the second UCI.
[0133] In some embodiments, the terminal device is caused to perform the PUSCH dropping within the OCC period by: dropping a plurality of PUSCH repetitions within the OCC period; and dropping the second UCI.
[0134] In some embodiments, based on determining that the at least one PUSCH repetition is to be dropped, the terminal device may perform the PUSCH dropping by dropping a plurality of PUSCH repetitions within the OCC period.
[0135] Fig. 14 illustrates a flowchart of a method 1400 implemented at a network device for a communication system. For the purpose of discussion, the method 1400 will be described from the perspective of the network device.
