Description

Technical Field

[0001] This application belongs to the field of communication technologies, and in particular, relates to an uplink transmission method, apparatus, and related devices. Background Art

[0002] Uplink control information (UCI) is transmitted on a physical uplink control channel (PUCCH). If a terminal is transmitting data on a physical uplink shared channel (PUSCH), and if PUCCH and PUSCH are transmitted simultaneously, that is, UCI remains on PUCCH, this will increase the cubic metric. If the resources of the PUCCH for transmitting UCI and the resources of the PUSCH overlap in time, multiplexing UCI and data on the PUSCH can avoid transmitting PUCCH and PUSCH simultaneously.

[0003] Currently, the prerequisite for a terminal to multiplex UCI on the PUSCH is that there is a resource overlap between the PUCCH and the PUSCH, but the case where uplink transmission skipping (UL Skipping) is enabled is not considered, resulting in insufficient processing time for the terminal to transmit UCI.

[0045] The uplink transmission method provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0046] Please refer to Figure 2 , Figure 2 which is a flowchart of an uplink transmission method provided by the embodiments of the present application. This method is used for a terminal, as Figure 2 shown, and includes the following steps:

[0047] Step 101: When the PUCCH overlaps with at least one PUSCH in the time domain, and the at least one PUSCH includes a PUSCH enabling uplink transmission skipping, uplink control information UCI is sent on one of the PUCCH and the at least one PUSCH; wherein, the time interval between the start symbol of the earliest channel among the PUCCH and the at least one PUSCH and the end symbol of the corresponding first downlink transmission channel (or referred to as the first downlink channel) is greater than or equal to the sum of the uplink multiplexing processing time and the first extension time, and the first extension time includes at least 1 time domain symbol.

[0048] If the physical uplink control channel (PUCCH) for transmitting uplink control information (UCI) overlaps with the physical uplink shared channel (PUSCH) in the time domain, the base station can meet the condition of the UCI multiplexing processing time of the terminal when scheduling the PUSCH, so that the UCI can be multiplexed on the PUSCH, avoiding the simultaneous transmission of the PUCCH.

[0049] The embodiment of the present invention takes into account the uplink transmission skipping function, increases the multiplexing processing time, and avoids the transmission failure caused by insufficient processing time. That is to say, when the PUCCH overlaps with at least one PUSCH in the time domain, and the at least one PUSCH includes a PUSCH enabling uplink transmission skipping, uplink control information UCI is sent on one of the PUCCH and the at least one PUSCH. Among them, one of the PUCCH and the at least one PUSCH can be understood as the target channel. The target channel may be the PUCCH or the PUSCH, which varies according to different policies.

[0050] Regardless of whether the target channel is the PUCCH or the PUSCH, due to the control of the multiplexing processing time of the channel, the time interval between the start symbol of the target channel and the end symbol of the corresponding first downlink transmission resource is greater than or equal to the sum of the uplink multiplexing processing time and the first extension time, which is sufficient to ensure the normal transmission of the UCI.

[0051] In this embodiment, the time interval between the starting symbol of the earliest channel among the PUCCH and the at least one PUSCH and the ending symbol of the corresponding first downlink transmission channel is greater than or equal to the sum of the uplink multiplexing processing time and the first extension time. By setting the time interval larger through the first extension time, the problem of insufficient processing time when the terminal multiplexes and transmits UCI on one of the channels among the PUCCH and the at least one PUSCH is avoided.

[0052] In a specific embodiment of the present invention, corresponding to the PUCCH and the at least one PUSCH, their corresponding downlink transmission channels are different. For the PUCCH, its corresponding downlink transmission channel is the PDSCH corresponding to the HARQ-ACK it transmits, or the PDCCH that schedules the PUCCH. For the PUSCH, its corresponding downlink transmission channel is the PDCCH that schedules the PUSCH, which is further described as follows.

[0053] That is to say, the corresponding first downlink transmission channel is: the physical downlink control channel (Physical Downlink Control Channel, abbreviated as PDCCH) that schedules the at least one PUSCH, or the PDCCH that schedules the PUCCH. The uplink multiplexing processing time is the maximum value of the multiplexing preparation times of the at least one PUSCH. That is to say, the first symbol of the earliest PUCCH or PUSCH among the PUCCH and the at least one PUSCH is not earlier than the symbol after the last symbol of any one of the PDCCHs that schedule the PUCCH and the at least one PUSCH, with an interval of the uplink multiplexing processing time and the first extension time.

[0054] Or

[0055] The corresponding first downlink transmission channel is: all physical downlink shared channels (Physical Downlink Shared Channel, abbreviated as PDSCH) corresponding to the UCI, and the UCI carries HARQ-ACK information of the PDSCH. The uplink multiplexing processing time is the maximum value of the multiplexing processing times of all PDSCHs corresponding to the UCI. That is to say, the first symbol of the earliest PUCCH or PUSCH among the PUCCH and the at least one PUSCH is not earlier than the symbol after the last symbol of any associated PDSCH, with an interval of the uplink multiplexing processing time and the first extension time. The HARQ-ACK transmission of the associated PDSCH is on the overlapping PUCCH or PUSCH.

[0056] In a specific embodiment of the present invention, scheduling the PDCCH of the PUCCH means: the PDCCH carrying the downlink control information (DCI for short) corresponding to the PUCCH. That is to say, the first symbol of the earliest PUCCH or PUSCH among the PUCCH and at least one PUSCH is not earlier than the symbol after the last symbol of any associated PDSCH with an interval of the uplink multiplexing processing time and the first extension time, and the HARQ-ACK transmission of the associated PDSCH is on the overlapping PUCCH or PUSCH.

[0057] As Figure 3a shown, the corresponding first downlink transmission channel is: the PDCCH scheduling the PUCCH. Figure 3a In the figure, label A is the starting symbol of the earliest channel among the PUCCH and the at least one PUSCH, Figure 3a wherein the starting symbol of the PUCCH is earlier than the starting symbol of at least one PUSCH; label C is the ending symbol of the PDCCH carrying the DCI corresponding to the PUCCH.

[0058] As Figure 3b shown, the corresponding first downlink transmission channel is: the transmission resource of the PDCCH scheduling the at least one PUSCH, Figure 3b In the figure, label A is the starting symbol of the earliest channel among the PUCCH and the at least one PUSCH, Figure 3b wherein the starting symbol of at least one PUSCH is earlier than the starting symbol of the PUCCH; label B is the ending symbol of the transmission resource of the PDCCH scheduling the at least one PUSCH.

[0059] In this embodiment, the uplink multiplexing processing time is the maximum value of the multiplexing preparation time of the at least one PUSCH.

[0060] The following explains several concepts in the specific embodiment of the present invention as follows.

[0061] Uplink multiplexing processing time:

[0062] When a single-slot PUCCH overlaps with a single-slot PUCCH or PUSCH, the UE uses the existing multiplexing rules to multiplex all UCI on one PUCCH or PUSCH. If there are multiple overlapping PUSCH / PUCCH, it is the maximum value of the uplink multiplexing processing time of all PDSCHs, that is where the uplink multiplexing processing time of the i-th PDSCH is:

[0063]

[0064] Among them, d 1,1 is related to the DMRS configuration, PDCCH and PDSCH configurations. In Figure 3c , T1 is

[0065] the maximum value of the uplink multiplexing processing time for all PUSCHs, that is where the uplink multiplexing processing time of the i-th PUSCH is:

[0066]

[0067] In Figure 3d , T2 is

[0068] Downlink scheduling time:

[0069] The downlink scheduling time between the end symbol of the PDCCH that schedules the PUSCH and the start symbol of the PUSCH is:

[0070] T proc,2 = max((N 2 + d 2,1 )(2048 + 144)·κ2 -μ ·T C , d 2,2 )

[0071] The terminal can also be referred to as a User Equipment (UE for short). N 2 Based on μ, as shown in Table 1 and Table 2 are UE processing capabilities 1 and 2 respectively;

[0072] If the start symbol of the PUSCH consists only of DM-RS, d 2,1 = 0, otherwise d 2,1 = 1;

[0073] If the scheduling DCI triggers a BWP handover, d 2,2 is equal to the handover time, otherwise d 2,2 = 0.

[0078] In the specific embodiments of the present invention, the transmission of UCI can select channels according to different strategies, which are described as follows.

[0079] In one embodiment of the present application, before transmitting uplink control information UCI on one of the PUCCH and the at least one PUSCH, the following steps are further included:

[0080] In the case that the MAC layer corresponding to the PUSCH to which the UCI is currently to be multiplexed does not generate a MAC PDU, multiplex the UCI into the at least one PUSCH, and the corresponding MAC layer includes the target PUSCH of the MAC PDU;

[0081] Or

[0082] Multiplex the UCI into the at least one PUSCH, and the corresponding MAC layer includes the target PUSCH of the MAC PDU;

[0083] Or

[0084] In the case that the MAC layers corresponding to the at least one PUSCH do not generate MAC PDUs, map the UCI to the PUCCH.

[0085] The following is a further example for illustration.

[0086] In the case that the MAC layer corresponding to the PUSCH to which the UCI is currently to be multiplexed does not generate a MAC PDU, multiplex the UCI into the PUSCH, and the corresponding MAC layer generates padding bits for multiplexing with the UCI; (UCI transmission strategy one).

[0087] Multiplex the UCI into the PUSCH, and the corresponding physical layer generates dummy bits for multiplexing with the UCI; (UCI transmission strategy two).

[0088] In the case that the MAC layers corresponding to the at least one PUSCH do not generate MAC PDUs, map the UCI to the PUCCH. (UCI transmission strategy three).

[0089] Corresponding to UCI transmission strategy one, in the case that the MAC layer corresponding to the PUSCH to which the UCI is currently to be multiplexed does not generate a MAC PDU, the UE notifies the MAC layer to generate a MAC PDU: the increased first extended time can be used for the change of the UE multiplexing process and the MAC layer to generate padding bits.

[0090] In strategy one, the physical layer of the UE first performs the UCI multiplexing related process, determines whether the UCI is multiplexed to the PUSCH of this carrier, and the UE notifies the MAC layer to generate a PDU only if the UCI is multiplexed to the PUSCH of this carrier. That is to say, the UCI multiplexing process of the UE has changed and additional processing time is required.

[0091] Corresponding to UCI transmission policy 2, when no MAC PDU is generated at the MAC layer corresponding to the PUSCH that the UCI is currently to be multiplexed on, the physical layer of the UE generates virtual bits and multiplexes them with the UCI; the first extended time added at this time can be used for the physical layer to generate virtual bits.

[0092] In policy 2, the physical layer uses virtual bits to multiplex the UCI on the PUSCH. The first extended time added at this time can be used for the change in the UE multiplexing process and the time for the physical layer to generate virtual bits.

[0093] In the above two policies, the processing time for the UE to perform PUSCH multiplexing is as follows: Assuming that the i-th PDCCH schedules the PUSCH of this carrier, then the time interval from the last symbol of this PDCCH to the start symbol of the earliest UL transmission among all overlapping PUCCH / PUSCH in the group containing the PUSCH of this carrier is:

[0094] Δ x3 is a value predefined in the protocol or a value related to the UE capability, and may also be related to the MAC PDU generation time, carrier switching time, virtual bit generation time, etc., and is reported by the UE to the network-side device.

[0095] If the UE has the i-th PDSCH on this carrier and its UCI (such as the corresponding HARQ-ACK) belongs to the group containing the PUSCH of this carrier, then the time interval from the last symbol of the i-th PDSCH to the start symbol of the earliest UL transmission among all overlapping PUCCH / PUSCH in this group is:

[0096] Δ x4 is a value predefined in the protocol or a value related to the UE capability, and is reported by the UE to the network-side device.

[0097] Among them, Δ x3 , Δ x4 are values greater than or equal to 0. For example, they can be multiple symbols such as 1, 2, 3, 4, etc. Δ x3 , Δ x4 is the above-mentioned first extended time.

[0098] This situation can only be applied to carriers configured with uplink transmission skipped, and not to carriers without uplink transmission skipped configured. That is, the newly defined processing time is only applied to carriers configured with uplink transmission skipped, or once a carrier is configured with uplink transmission skipped, this situation will be applied to all carriers, that is, the newly defined processing time is applied to all carriers.

[0099] In a specific embodiment of the present invention, if, according to certain multiplexing strategies, the PUSCH for multiplexing UCI is a PUSCH skipped in uplink transmission and there is no PDU at the MAC layer, in order to ensure the normal transmission of UCI, the service data in the PUSCH for transmitting the UCI is generated virtual data or padding data generated by the MAC layer.

[0100] Specific examples are as follows.

[0101] If there is no data at the MAC layer, padding bits will be used to generate a PDU. If there is no data in the MACs of both Component Carriers (CC) 1 and CC2, and the network schedules the PUSCH of CC1, according to a certain strategy, if UCI is to be multiplexed onto the PUSCH of CC1, even if there is no data at the MAC layer, padding bits will still be used to generate a PDU.

[0102] In this case, for a carrier configured with uplink transmission skipped, the time interval from the DCI scheduling a PUSCH to the start symbol of the PUSCH (i.e., the processing time required for the UE to prepare for the PUSCH) is:

[0103] T proc,2 +d x1 where d x1 is a pre-defined value in the protocol or a value related to the UE capability, and is reported by the UE to the network device.

[0104] For a carrier configured with uplink transmission skipped, the time interval from the last symbol of the scheduled PDSCH to the start symbol of the PUCCH carrying the HARQ-ACK corresponding to the PDSCH is:

[0105] T proc,1 +d x2 where d x2 is a pre-defined value in the protocol or a value related to the UE capability, and is reported by the UE to the network device. d x1 and d x2 can be regarded as the second extended time.

[0106] Alternatively, the physical layer virtual bits of the UE are used for PUSCH transmission, and UCI will be multiplexed onto the PUSCH.

[0107] For the processing time of the UE for PUSCH multiplexing, assuming that the i-th PDCCH schedules the PUSCH, then the time interval from the last symbol of the PDCCH to the start symbol of the earliest UL transmission among all the overlapping PUCCH / PUSCH in the group containing the PUSCH is:

[0108] Δy3 It is a pre - defined value in the protocol or a UE - capability - related value, and is reported by the UE to the network - side device.

[0109] For the i - th PDSCH, if its UCI (e.g., the corresponding HARQ - ACK, Hybrid Automatic Repeat reQuest (HARQ)) belongs to a group containing a PUSCH / PUCCH, then the time interval between the last symbol of the i - th PDSCH and the start symbol of the earliest UL transmission among all overlapping PUCCH / PUSCH in this group is:

[0110] Δ y4 It is a pre - defined value in the protocol or a UE - capability - related value, and is reported by the UE to the network - side device.

[0111] Among them, Δ y3 , Δ y4 can be regarded as the first extended time, Δ y3 , Δ y4 is a value greater than or equal to 0. For example, it can be 1, 2, 3, 4 and other multiple symbols. It is required to satisfy: the time interval between the end symbol of any PDSCH of this UE and the start symbol of the earliest PUCCH / PUSCH among all PUCCH / PUSCH overlapping with the PUCCH where its HARQ - ACK is transmitted is the maximum value of the processing time of all PDSCHs, that is

[0112] Meanwhile, for the time interval between the end symbol of any PDCCH and the start symbol of the earliest PUCCH / PUSCH among the overlapping PUCCH / PUSCH it schedules is the maximum value of the processing time of all PUSCHs, that is

[0113] In this case, for the carrier configured with uplink transmission skipping, the time interval between the DCI scheduling a PUSCH and the start symbol of the PUSCH (i.e., the processing time required for the UE to prepare for the PUSCH) is:

[0114] T proc,2 +d y1 , d y1 is a pre - defined value in the protocol, or a UE - capability - related value, and is reported by the UE to the network - side device. d y1 can be regarded as the second extended time. As shown in Figure 3f , T4 is T proc,2 , and the downlink scheduling time is the preparation time of the PUSCH.

[0115] For a carrier configured with uplink transmission skipping, the time interval between the last symbol of the scheduled PDSCH and the start symbol of the PUCCH scheduled for HARQ-ACK corresponding to the PDSCH is:

[0116] T proc,1 + d y2 , d y2 is a pre-defined value in the protocol or a UE-capability related value, and is reported by the UE to the network-side device. d y2 can be regarded as the second extended time. As Figure 3e shown, T3 is T proc,1 , and the downlink scheduling time is the processing time of the PDSCH.

[0117] In the case where no MAC PDU is generated at the MAC layer corresponding to the at least one PUSCH, map the UCI to the PUCCH, that is, instead of transmitting the UCI by multiplexing the PUSCH, directly transmit the UCI through the PUCCH.

[0118] For transmission strategy three, as long as one carrier is configured with uplink transmission skipping, the UE first needs to notify the MAC layer to generate a MAC PDU, and then according to the multiplexing rule, multiplex the UCI to the corresponding carrier. Therefore, it is necessary to define a new UE processing capability.

[0119] For example, in the case where CC1 is configured with uplink transmission skipping and CC2 is not configured with uplink transmission skipping:

[0120] If CC2 generates a PDU and CC1 does not generate a PDU, the UCI will be multiplexed to the PUSCH of CC2;

[0121] If the CC1 MAC generates a PDU and the CC2 MAC does not generate a PDU, then the UCI will be multiplexed to the PUSCH of CC1;

[0122] If both the CC1 and CC2 MACs generate PDUs, the UCI will be determined according to the multiplexing rule to be multiplexed to the PUSCH of which CC;

[0123] If neither the CC1 nor the CC2 MAC generates a PDU, then the UCI will be transmitted using the PUCCH.

[0124] Therefore, due to the change in the process of notifying the MAC layer to generate a PDU and the UCI multiplexing, more processing time may be introduced.

[0125] It should be understood that the meaning of the virtual data in the embodiments of the present invention is the data that needs to be transmitted on the PUSCH and is not generated based on actual service requirements.

[0126] The processing time for the UE to perform PUSCH multiplexing. Assume that the i-th PDCCH schedules the PUSCH on this carrier. Then, the time interval from the last symbol of this PDCCH to the start symbol of the earliest UL transmission among all overlapping PUCCH / PUSCHs in the group containing the PUSCH on this carrier is:

[0127] Δ z3 It is a value predefined in the protocol or a value related to the UE capability, and is reported by the UE to the network device.

[0128] If the UE has the i-th PDSCH on this carrier and its UCI (e.g., the corresponding HARQ-ACK) belongs to the group containing the PUSCH on this carrier, then the time interval from the last symbol of the i-th PDSCH to the start symbol of the earliest UL transmission among all overlapping PUCCH / PUSCHs in this group is:

[0129] Δ z4 It is a value predefined in the protocol or a value related to the UE capability, and is reported by the UE to the network device.

[0130] Among them, Δ z3 , Δ z4 is a value greater than or equal to 0. For example, it can be multiple symbols such as 1, 2, 3, 4, etc. Δ z3 , d z4 can be regarded as the first extended time.

[0131] In this embodiment, for the carrier configured with uplink transmission skipped, the time interval from the DCI scheduling the PUSCH to the start symbol of the PUSCH (i.e., the processing time required for the UE to prepare for the PUSCH) is:

[0132] T proc,2 +d z1 , d z1 is a value predefined in the protocol, or a value related to the UE capability, and is reported by the UE to the network device. d z1 can be regarded as the second extended time.

[0133] For the carrier configured with uplink transmission skipped, the time interval from the last symbol of the scheduled PDSCH to the start symbol of the PUCCH scheduled for the HARQ-ACK corresponding to this PDSCH is:

[0134] T proc,1 +d z2 , d z2 is a value predefined in the protocol. d z2 can be regarded as the second extended time.

[0135] Among them, d x1 , dx2 , d y1 , d y2 , d z1 , d z2 is a value greater than or equal to 0. For example, it can be multiple symbols such as 1, 2, 3, 4, etc.

[0136] The newly defined processing time can be applied only to the carriers configured with uplink transmission skipping, rather than to the carriers without uplink transmission skipping configured. Or, once a carrier is configured with uplink transmission skipping, the newly defined processing time will be applied to all carriers.

[0137] That is to say, in an embodiment of the present application, the time interval between the start symbol of any one of the PUCCH and at least one PUSCH and the end symbol of the corresponding second downlink transmission channel is greater than or equal to the sum of the downlink scheduling time and the second extension time, and the second extension time includes at least 1 time domain symbol.

[0138] Wherein, the second downlink transmission channel corresponding to the PUSCH is: the PDCCH scheduling the PUSCH, and the downlink scheduling time is the preparation time of the PUSCH;

[0139] Or, the second downlink transmission of the PUCCH is: the PDSCH corresponding to the UCI transmitted by the PUCCH, and the downlink scheduling time is the processing time of the PDSCH.

[0140] The time interval from the end symbol of the PDCCH scheduling the PUSCH to the start symbol of the PUSCH (i.e., the processing time required for the UE to prepare for the PUSCH) is:

[0141] T proc,2 +d x1 , d x1 is a value predefined in the protocol or a value related to the UE capability, and is reported by the UE to the network side device.

[0142] Such as Figure 3f shown, T4 is T proc,2 , and the downlink scheduling time is the preparation time of the PUSCH.

[0143] The time interval between the end symbol of the scheduled PDSCH and the start symbol of the PUCCH carrying the HARQ-ACK corresponding to the PDSCH is:

[0144] T proc,1 +d x2 , d x2 is a value predefined in the protocol or a value related to the UE capability, and is reported by the UE to the network side device, d x1 , d x2It can be regarded as the second extended time.

[0145] As Figure 3e shown, T3 is T proc,1 , and the downlink scheduling time is the processing time of the PDSCH.

[0146] In an embodiment of the present application, the first extended time or the second extended time is predefined, or the first extended time or the second extended time is determined according to at least one of the following: terminal capability, MAC PDU generation time, carrier switching time, and virtual bit generation time, and can be reported by the UE to the network side device.

[0147] The present application also provides an uplink transmission method for a terminal. The method includes: when the physical uplink control channel PUCCH overlaps with at least one physical uplink shared channel PUSCH in the time domain, and at least one of the PUSCHs includes a PUSCH that enables uplink transmission skipping, sending uplink control information UCI on one of the PUCCH and the at least one PUSCH;

[0148] Wherein, the time interval between the start symbol of any one of the PUCCH and the at least one PUSCH and the end symbol of the corresponding second downlink transmission channel is greater than or equal to the sum of the downlink scheduling time and the second extended time, and the second extended time includes at least 1 time domain symbol.

[0149] In this embodiment, the time interval between the start symbol of any one of the PUCCH and the at least one PUSCH and the end symbol of the corresponding second downlink transmission channel is greater than or equal to the sum of the downlink scheduling time and the second extended time. By setting the time interval larger through the second extended time, the problem that the processing time is insufficient when the terminal multiplexes and sends UCI on one of the PUCCH and the at least one PUSCH is avoided.

[0150] Further, the second downlink transmission channel corresponding to the PUSCH is: the PDCCH that schedules the PUSCH, and the downlink scheduling time is the preparation time of the PUSCH.

[0153] The time interval from the end symbol of the PDCCH scheduling the PUSCH to the start symbol of the PUSCH (i.e., the processing time required for the UE to prepare for the PUSCH) is:

[0154] T proc,2 +d x1 ,where d x1 is a pre-defined value in the protocol or a UE capability-related value, and is reported by the UE to the network device.

[0155] As Figure 3f shown, T4 is T proc,2 , and the downlink scheduling time is the preparation time of the PUSCH.

[0156] The time interval from the end symbol of the scheduled PDSCH to the start symbol of the PUCCH carrying the HARQ-ACK corresponding to the PDSCH is:

[0157] T proc,1 +d x2 , where d x2 is a pre-defined value in the protocol or a UE capability-related value, and is reported by the UE to the network device, and d x1 、d x2 can be regarded as the second extended time.
