In the communication environment 100, a plurality of communication devices, including a terminal device 110 and a network device 120, can communicate with each other.
[0047] In the example of FIG. 1A, FIG. 1B or FIG. 1 C, the terminal device 110 may be a UE and the network device 120 may be a base station serving the UE. The serving area of the network device 120 may be called a cell 102.
[0048] As shown in FIG. 1B, the network device 120 may communicate with the terminal device 110 via at least one of the TRPs / panels 130-1, 130-2, 130-3 and 130-4.

In downlink, the network device 120 is a transmitting (TX) device (or a transmitter) and the terminal device 110 is a receiving (RX) device (or a receiver) . In downlink, the network device 120 may transmit downlink transmission to the terminal device 110 via one or more beams or one or more TCI states (or downlink TCI states or joint TCI states) . For example, as illustrated in FIG. 1 C, the network device 120 transmits downlink transmission to the terminal device 110 via a plurality of beams and / or a plurality of TCI states (e.g. a plurality of downlink TCI states and / or a plurality of joint TCI states) . Correspondingly, in uplink, the network device 120 is a RX device (or a receiver) and the terminal device 110 is a TX device (or a transmitter) . In uplink, the terminal device 110 may transmit uplink transmission to the network device 120 via one or more beams or one or more TCI states (or uplink TCI states or joint TCI states) . For example, as illustrated in FIG. 1 C, the terminal device 110 transmits uplink transmission to the network device 120 via a plurality of beams and / or a plurality of TCI states (e.g. a plurality of uplink TCI states and / or a plurality of joint TCI states) .

[0053] In some example embodiments, if the terminal device 110 is a terminal device and the network device 120 is a network device, a link from the network device 120 to the terminal device 110 is referred to as a downlink (DL) , while a link from the terminal device 110 to the network device 120 is referred to as an uplink (UL) .

For example, in case of occasions for PDCCH monitoring (or slots for PDCCH monitoring occasions or slots for receiving or detecting the at least one DCI) corresponding to more than one transmission occasion (e.g. a first occasion and a second occasion) of one first uplink channel overlap, at least one DCI corresponding to the overlapped occasions for PDCCH monitoring (or overlapped slots for PDCCH monitoring occasions or overlapped slots for receiving or detecting the at least one DCI) may be associated with the second set of events (and / or second set of cells) . For example, the second set of events (and / or the second set of cells) may be the union of a fifth set of events (and / or a fifth set of cells) associated with a first occasion of the first uplink channel and a sixth set of events (and / or a sixth set of cells) associated with a second occasion of the first uplink channel (e.g. and / or excluding the reduplicative events and / or cells) .
[0141] In some embodiments, the events in the second set of events (and / or corresponding to the second set of cells) may be in increasing (or decreasing order) of event ID and / or cell index. In some embodiments, the events in the second set of events (and / or corresponding to the second set of cells) may be in increasing (or decreasing order) of event ID firstly and then cell index. In some embodiments, the events in the second set of events (and / or corresponding to the second set of cells) may be in increasing (or decreasing order) of cell index firstly and then event ID.
[0142] In some embodiments, the DCI in one monitoring occasion and / or the at least one DCI may schedule a resource for a second uplink channel for transmission of at least one measurement report and / or may notify (or confirm or indicate notification or confirmation of) the transmission of the at least one measurement report on the second uplink channel. In some embodiments, a payload size for the at least one measurement report on the second uplink channel may be based on the number of events associated with the DCI or the occasion for PDCCH monitoring for the DCI or associated with the at least one DCI detected in the monitoring occasion. For example, the payload size for the at least one measurement report on the second uplink channel may be based on the number of events (e.g. in the second set of events (and / or the second set of cells) (e.g. determined according to embodiments in this disclosure) ) associated with the DCI, e.g. based on the number of events associated with the at least one first occasion corresponding to the monitoring occasion for the DCI. In some embodiments, each measurement report may be associated with one event and / or one cell.
[0143] In some embodiments, the payload size may be determined based on the number of associated events (e.g. number of events in the second set of events and / or the second set of cells) . For example, in some embodiments, even some events are not triggered, the number of bits for the measurement report corresponding to the events may be reserved / padded. In this way, the payload size can be fixed for the scheduling based on one DCI, and even iftransmission of first information for some events is missed, it's still possible to transmit the corresponding measurement report on the second uplink channel.
[0144] In some embodiments, the bit fields for one measurement report associated with the events and / or cells may be in increasing order of the event ID and cell index of the second set of events (and / or second set of cells) . In some embodiments, if the second set of events and / or the second set of cells include the serving cell, the cell index corresponding to the measurement report of the serving cell may be omitted in the measurement report, the measurement report corresponding to the serving cell may be placed / reserved at the beginning of the payload. In some embodiments, one measurement report may comprise one or more of: indication of cell index, indication (s) of measurement resource (s) , measurement result (s) of measurement resource (s) , indication (s) of reference measurement resource (s) and measurement result (s) of reference measurement resource (s) .
[0145] In some embodiments, PDCCH monitoring for the at least one DCI is in a third occasion or a third slot (e.g. represented as n3) . In some embodiments, the terminal device may receive or detect at least one DCI in a third occasion or the terminal device may receive or detect at least one PDCCH in the third occasion or the third slot. In some embodiments, a third set of events and / or a third set of cells may be associated with the at least one DCI, wherein the third set of events and / or the third set of cells may be based on a third group of occasions (or represented as a third group of slots) . In some embodiments, the third group of occasions or the third group of slots may be based on one or more of: the third occasion and a third set of offsets, the third occasion and a third time duration, a fourth timing, a fifth timing, the third occasion and a fourth offset, the third occasion and a fifth offset or at least one uplink and downlink configuration. For example, the at least one DCI may be in at least one PDCCH monitoring occasion (or in a third occasion or a third slot) , and a third set of events and / or a third set of cells (e.g. at least one event of the third set of events and / or the third set of cells may be triggered, and corresponding first information may be transmitted on at least one occasion on the first uplink channel) may be associated with the at least one DCI. In some embodiments, the third set of events and / or the third set of cells may be based on the third group of occasions or the third group of slots.
[0146] In some embodiments, (for example, as shown in FIG. 5A) , the third group of occasions may be determined based on the third occasion and the third set of offsets. In some embodiments, the third group of occasions or the third group of slots may be determined based on the third occasion (e.g. the third slot) (e.g. represented as n3) and the third set of offsets (or represented as the third set of intervals) (e.g. represented as k3, i) . In some embodiments, the third group of occasions may be represented as n3 -k3, i. In some embodiments, n3 may be non-negative integer. In some embodiments, n3 may be an index of a slot. In some embodiments, 0 ≤ n3 ≤ 639. In some embodiments, n3 may be n. In some embodiments, i may be non-negative integer. In some embodiments, i may be an index of offset in the third set of offsets. In some embodiments, 0 ≤ i ≤ Nk, 3 --1. In some embodiments, Nk, 3 may be the number of offsets in the third set of offsets. In some embodiments, Nk, 3 may be positive integer. In some embodiments, 1 ≤ Nk, 3 ≤ 32. In some embodiments, k3, i may be the value of offset with index i (or the (i + 1) -th offset) in the second set of offsets. In some embodiments, k3, i may be non-negative integer. In some embodiments, 0 ≤ k3, i ≤ 16 or 0 ≤ k3, i ≤ 32 or 0 ≤ k3, i ≤ 64.
[0147] In some embodiments, (for example, as shown in FIG. 5B) , the third group of occasions or the third group of slots may be determined based on the third occasion, the third time duration (and / or the fourth timing) . In some embodiments, the third group of occasions or the third group of slots may be determined based on the third occasion and a third time duration (e.g. a third number of slots or symbols) (e.g. represented as K3 occasions or K3 slots or K3 sub-slots or K3 symbols) (and / or a fourth offset, e.g. represented as T4) . In some embodiments, the third group of occasions or the third group of slots may be the K3 occasions (or K3 slots or K3 sub-slots or K3 symbols) before a fourth timing. In some embodiments, the third time duration may comprise a third number of slots or a third number of symbols. For example, the third time duration may be represented as K3 occasions or K3 slots or K3 sub-slots or K3 symbols. In some embodiments, K3 may be non-negative integer. In some embodiments, 0 ≤ K3 ≤ 16 or 0 ≤ K3 ≤ 32 or 0 ≤ K3 ≤ 64. In some embodiments, T4 may be non-negative integer. In some embodiments, 0 ≤ T4 ≤ 4 or 0 ≤ T4 ≤ 16 or 0 ≤ T4 ≤ 32 or 0 ≤ T4 ≤ 64. In some embodiments, the fourth timing may be based on the third occasion and the fourth offset. In some embodiments, the fourth timing may be represented as n3 --T4 or n3 or n3 --1. In some embodiments, the fourth timing may be the ending of the third occasion (or the third slot) or the last symbol of the third occasion (or the third slot) or the beginning of the third occasion (or the third slot) or (the beginning or ending) of the first slot before the third occasion or the first uplink slot before the third occasion or the first slot with at least one occasion of the first uplink channel before the third occasion (or the third slot) . In some embodiments, the third group of occasions or the third group of slots may be the K3 occasions (or K3 slots or K3 sub-slots or K3 symbols) after a fifth timing. In some embodiments, the third group of occasions or the third group of slots may be a number of occasions or slots between the fifth timing and the fourth timing. In some embodiments, the fifth timing may be based on the third occasion and a fifth offset (e.g. represented as T5) . In some embodiments, the fifth timing may be represented as n3 -T5. In some embodiments, T5 may be non-negative integer. In some embodiments, 0 ≤ T5 ≤ 4 or 0 ≤ T5 ≤ 16 or 0 ≤ T5 ≤ 32 or 0 ≤ T5 ≤ 64. In some embodiments, T5 ≥ T4. In some embodiments, the third group of occasions or the third group of slots may be occasions or slots from n3 -T4 -K3 + 1 to n3 -T4 or from n3-T4 -K3 to n3 -T4 -1 or from n3 -T5 to n3-T4 or from n3-T5 to n3-T4-1 or from n3-T5+1 to n3-T4 or from n3-T5 + 1 to n3 -T4 -1. In some embodiments, n3 may be one or more value of n. In some embodiments, n3 may be n. In some embodiments, n3 may non-negative integer. In some embodiments, n3 may an index of a slot or an index of the first slot. In some embodiments, 0 ≤ n3 ≤ 2559.
[0148] In some embodiments, n may be replaced by n3 or n1 or n2 for some embodiments in this disclosure.
[0149] In some embodiments, the terminal device may transmit first information in at least one occasion in the third group of occasions (or the third group of slots) or overlapping with the third group of occasions (or the third group of slots) . In some embodiments, the first information may indicate at least one event is triggered.
[0150] In some embodiments, the third group of occasions may be determined based on at least one uplink and downlink configuration (e.g. slot format configuration or tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated) . For example, if the resource (or configured symbols) for at least one first uplink channel overlapping with at least one symbol (e.g. configured as downlink and / or flexible) in one occasion (or slot) , the occasion (or slot) may be skipped or omitted or excluded in the first group of occasions (or slots) .
[0151] In some embodiments, the third set of events may be same as or a subset of the plurality of events. In some embodiments, the third set of cells may be same or a subset of the plurality of cells configured with event driven reporting. In some embodiments, the third set of events and / or the third set of cells may be those events and / or cells with corresponding instance (s) (e.g. from the plurality of instances) and / or with corresponding transmission occasions (e.g. from the first plurality of occasions) on associated first uplink channel overlapping or included in the third group of occasions (or slots) . In some embodiments, if there is at least one instance / occasion corresponding to one event and / or one cell overlapping or included in the third group of occasions or the third group of slots, the event and / or the cell may be counted or considered one time in the third set of events and / or the third set of cells.
[0152] In some embodiments, the at least one configuration comprises one or more of: the third set of offsets, the third time duration, a fourth offset or a fifth offset, wherein the third set of offsets and / or the third time duration are associated with one or more of: at least one event or at least one cell configured with event driven reporting, the at least one first uplink channel, all the events, or all the cells configured with event driven reporting. In some embodiments, the at least one configuration may include the third set of offsets and / or the third time duration and / or the fourth offset (and / or the fifth offset) . In some embodiments, the third set of offsets and / or the third time duration may be associated with at least one event or at least one cell configured with event driven reporting or associated with the at least one first uplink channel or associated with all the events and / or cells configured with event driven reporting. In some embodiments, the third time duration and / or the maximum value of third time duration may be based on UE capability. In this way, DCI in one monitoring occasion can be associated with at least one event, based on the multiplexing of associated at least event with one DCI, even if transmission of first information for some events is missed, it's still possible to transmit the corresponding measurement report for the at least one event on the second uplink channel.
[0153] In some embodiments, the payload size for the at least one measurement report on the second uplink channel may be based on the number of events (e.g. in the third set of events (and / or the third set of cells) ) associated with the DCI. For example, the payload size may be based on the number of events with at least one associated transmission occasion (from the first plurality of occasions) or event instance (from the second plurality of instances) overlapping with at least one of the third group of occasions.
[0154] In some embodiments, the payload size may be determined based on the number of associated events (e.g. number of events in the third set of events and / or the third set of cells) . In some embodiments, the bit fields (e.g. one or more of: cell index, indication (s) of measurement resource (s) , measurement results of measurement resource (s) ) associated with the events and / or cells may be in increasing order of the event ID and cell index of the third set of events (and / or third set of cells) and / or the increasing order of the occasions or instances overlapping with the at least one third group of occasions. In some embodiments, if there is at least one instance / occasion corresponding to one event and / or one cell overlapping or included in the third group of occasions, the event and / or the cell may be counted or considered one time for the payload generation for the at least one measurement report.
[0155] In some embodiments, in case of the second set of events and / or the second set of cells include the serving cell, the cell index corresponding to the measurement report of the serving cell may be. In some embodiments, the at least one DCI in the at least one monitoring occasion may schedule a same PUSCH transmission for the at least one measurement report. In some embodiments, the at least one DCI may be UL grant DCI, e.g. DCI format.
[0156] In some embodiments, the terminal device 110 does not expect a reception of a first PDCCH reception starting earlier than a second PDCCH reception, if the first or last symbol of a first transmission occasion of a first one of first uplink channel (e.g. represented as first uplink channel #1) associated with a first measurement report is later than or no earlier than the first of last symbol of a second transmission occasion of a second one of first uplink channel (e.g. represented as first uplink channel #2) associated with a second measurement report. For example, the terminal device 110 may not expect to receive a first PDCCH reception starting earlier than a second PDCCH reception, if the first or last symbol of a first transmission occasion of a first one of first uplink channel (e.g. represented as first uplink channel #1) associated with the first measurement report is later than or no earlier than the first of last symbol of a second transmission occasion of a second one of first uplink channel (e.g. represented as first uplink channel #2) associated with the second measurement report. In some embodiments, the first PDCCH reception may be with a first DCI with confirming or notifying transmission of a first measurement report and / or scheduling resource for transmission of the first measurement report. In some embodiments, the second PDCCH reception may be with a second DCI with confirming or notifying transmission of a second measurement report and / or scheduling a resource for transmission of the second measurement report.
[0157] In some other embodiments, the terminal device 110 does not a expect transmission of a first one of second uplink channel (e.g. represented as second uplink channel #1) starting earlier than an end of a second one of second uplink channel (e.g. represented as second uplink channel #2) , if the first or last symbol of the first PDCCH is later than or no earlier than the first or last symbol of the second PDCCH and / or if the first or last symbol of a first transmission occasion of a first one of first uplink channel (e.g. represented as first uplink channel #1) associated with the first measurement report is later than or no earlier than the first of last symbol of a second transmission occasion of a second one of first uplink channel (e.g. represented as first uplink channel #2) associated with the second measurement report. For example, the terminal device 110 may not expect to be scheduled to transmit a first one of second uplink channel (e.g. a first PUSCH) (e.g. represented as second uplink channel #1) starting earlier than the end of a second one of second uplink channel (e.g. a second PUSCH) (e.g. represented as second uplink channel #2) , if the first or last symbol of the first PDCCH is later than or no earlier than the first or last symbol of the second PDCCH and / or if the first or last symbol of a first transmission occasion of a first one of first uplink channel (e.g. represented as first uplink channel #1) associated with the first measurement report is later than or no earlier than the first of last symbol of a second transmission occasion of a second one of first uplink channel (e.g. represented as first uplink channel #2) associated with the second measurement report. In some embodiments, the first one of second uplink channel (e.g. represented as second uplink channel #1) may comprise a first measurement report, and the first one of second uplink channel (e.g. represented as second uplink channel #2) may be scheduled by a first PDCCH. In some embodiments, the second one of second uplink channel (e.g. represented as second uplink channel #2) may comprise a second measurement report, and the second one of second uplink channel (e.g. represented as second uplink channel #2) may be scheduled by a second PDCCH.
[0158] In some embodiments, the network device 120 may transmit at least one configuration for a plurality of events and / or a plurality of cells configured with event driven reporting to the terminal device 110. In other words, the terminal device 110 may receive the at least one configuration for the plurality of events and / or the plurality of cells configured with event driven reporting from the network device 120.
[0159] In some embodiments, the terminal device 110 may transmit the first information on the first uplink channel if at least one event of a first set of events and / or a first set of cells is triggered. In other words, the network device 120 may receive the first information on the first uplink channel (e.g. if at least one event of a first set of events and / or a first set of cells is triggered) .
[0160] In some embodiments, the terminal device 110 may generate and / or transmit first information (e.g. represented as pre-notification codebook) at the first occasion (e.g. a first slot) (e.g. represented as n1) on the first uplink channel in case of at least one event of a first set of events and / or a first set of cells is triggered. In some embodiments, the first information may be generated based on a first group of occasions (or a first group of slot) .
[0161] In some embodiments, (for example, as shown in FIG. 6A and FIG. 7A) , the first group of occasions or the first group of slots may be determined based on the first occasion and the first set of offsets. In some embodiments, the first group of occasions or the first group of slots may be determined based on the first occasion (e.g. the first slot) (e.g. represented as n1) and the first set of offsets (or intervals) (e.g. represented as k1, i) . In some embodiments, the first group of occasions or the first group of slots may be represented as n1-k1, i. In some embodiments, n1 may be non-negative integer. In some embodiments, n1 may be an index of a slot. In some embodiments, 0 ≤ n1 ≤ 639. In some embodiments, n1 may be n. In some embodiments, i may be non-negative integer. In some embodiments, i may be an index of offset in the first set of offsets. In some embodiments, 0 ≤ i ≤ Nk, 1 --1. In some embodiments, Nk, 1 may be the number of offsets in the first set of offsets. In some embodiments, Nk, 1 may be positive integer. In some embodiments, 1 ≤ Nk, 1 ≤ 32. In some embodiments, k1, i may be the value of offset with index i (or the (i + 1) -th offset) in the first set of offsets. In some embodiments, k1, i may be non-negative integer. In some embodiments, 0 ≤ k1, i ≤ 16 or 0 ≤ k1, i ≤ 32 or 0 ≤ k1, i ≤ 64.
[0162] In some embodiments, (for example, as shown in FIG. 6B and FIG. 6B) , the first group of occasions or the first group of slots may be determined based on the first occasion and a first time duration (and / or the first timing) . In some embodiments, the first group of occasions or the first group of slots may be determined based on the first occasion and the first time duration (e.g. a first number of slots or a first number of symbols) (e.g. represented as K1 occasions or K1 slots or K1 sub-slot or K1 symbols) (and / or a first offset, e.g. represented as T1) . In some embodiments, the first time duration may comprise a first number of slots or a first number of symbols. For example, the first time duration may be represented as K1 occasions or K1 slots or K1 sub-slots or K1 symbols. In some embodiments, K1 may be non-negative integer. In some embodiments, 0 ≤ K1 ≤ 16 or 0 ≤ K1 ≤ 32 or 0 ≤ K1 ≤ 64. In some embodiments, T1 may be non-negative integer. In some embodiments, 0 ≤ T1 ≤ 4 or 0 ≤ T1 ≤ 16 or 0 ≤ T1 ≤ 32 or 0 ≤ T1 ≤ 64. In some embodiments, the first group of occasions or the first group of slots may be the K1 occasions (or K1 slots or K1 sub-slot or K1 symbols) before a first timing. In some embodiments, the first timing may be based on the first occasion and the first offset. In some embodiments, the first timing may be represented as n1-T1 or n1 or n1-1. In some embodiments, the first timing may be the ending of the first occasion (or the first slot) or the last symbol of the first occasion (or the first slot) or the beginning of the first occasion (or the first slot) or (the beginning or ending) of the first slot before the first occasion or the first uplink slot before the first occasion or the first slot with occasion for transmission of the first uplink channel before the first occasion (or the first slot) . In some embodiments, the first group of occasions or the first group of slots may be occasions (or slots) from n1-T1 -K1 + 1 to n1-T1 or from n1-T1 -K1 to n1-T1 -1 or from n1 -T1 -K1 + 1 to n1-T1 -1 or from n1-T1 -K1 to n1-T1.
[0163] In some embodiments, the first group of occasions or the first group of slots may be determined based on at least one uplink and downlink configuration. For example, the terminal device 110 may determine the first group of occasions or the first group of slots based on at least one uplink and downlink configuration (e.g. slot format configuration or tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated ) . For example, if the resource (or configured symbols) for the first uplink channel overlapping with at least one symbol (e.g. configured as downlink and / or flexible) in one occasion (or slot) , the occasion (or slot) may be skipped or omitted or excluded in the first group of occasions (or the first group of slots) .
[0164] In some embodiments, the at least one configuration may include one or more of:the first set of offsets, the first timing, the first offset or the first time duration. In some embodiments, the first set of offsets and / or the first time duration may be associated with one or more of: the first uplink channel, at least one event configured with event driven reporting or at least one cell configured with event driven reporting. In some embodiments, the first time duration and / or the maximum value of first time duration may be based on UE capability.
[0165] In some embodiments, the at least one configuration comprises a first plurality of occasions or a first group of slots. In some embodiments, the first plurality of occasions or the first group of slots may be associated with the first uplink channel. For example, the at least one configuration may include a first plurality of occasions (or a first plurality of slots) or a first periodicity and / or a first offset. For example, the first plurality of occasions or the first periodicity and / or the first offset may be associated with the first uplink channel or associated with at least one event or at least one cell configured with event driven reporting. In some embodiments, the first plurality of occasions or the first plurality of slots may be based on the first periodicity and / or the first offset. In some embodiments, the first plurality of occasions or the first plurality of slots may be applied for transmission of first information (pre-notification codebook) . In some embodiments, the first occasion may be one occasion in the first plurality of occasions or based on the first periodicity and / or the first offset.
[0166] In some embodiments, the at least one configuration may include a second plurality of instances corresponding to one event and / or one cell configured with event driven reporting or corresponding to at least one event in the plurality of events and / or at least one cell in the plurality of cells configured with event driven reporting. In some embodiments, the second plurality of instances may be configured for assessing whether event is triggered or satisfied or may be based on at least one occasion (e.g. the third periodicity and / or third offset) corresponding to a first plurality of measurement resources (e.g. for new beam measurement) and / or no later than CSI reference timing and / or fourth periodicity and / or fourth offset corresponding to at least one reference measurement resource (e.g. for current beam measurement) and / or no later than CSI reference timing. In some embodiments, the first plurality of measurement resources and / or the at least one reference measurement resource may be associated with one event and / or one cell configured with event driven reporting. In some embodiments, at one instance, an event may be triggered or assessed or monitored, while the transmission of the pre-notification information may be based on at least one occasion from the first plurality of occasions.
[0167] In some embodiments, the first set of events may be same as or a subset of the plurality of events. In some embodiments, the first set of cells may be same or a subset of the plurality of cells configured with event driven reporting. For example, the first set of events and / or the first set of cells may be those events and / or cells with corresponding instance (s) (e.g. from the plurality of instances) overlapping or included in the first group of occasions (or the first group of slots) . In some embodiments, if there is more than one instance / occasion corresponding to one event and / or one cell overlapping or included in the first group of occasions, the event and / or the cell is counted (or considered) one time for the pre-notification codebook generation.
[0168] In some embodiments, a size of the first information may be based on at least one of: the number of events, the number of cells of the first set of events, or the first set of cells. In some other embodiments, the size of the first information may be based on the number of occasions in the first group of occasions or the first group of slots. For example, ifthere is more than one instance or occasion corresponding to one same event and / or one same cell, only one instance or occasion may be counted or used for the pre-notification codebook generation, e.g. the first or the last one instance / occasion may be applied. In some embodiments, a location of bit (e.g. corresponding to one event and / or one cell) may be determined based on the increasing order based one or more of: instance or occasion indexes or event ID or cell index. In some embodiments, a location of bit (e.g. corresponding to one event and / or one cell) may be determined based on the increasing order of event ID firstly and then cell index. In some embodiments, a location of bit (e.g. corresponding to one event and / or one cell) may be determined based on the increasing order of cell index firstly and then event ID.
[0169] In some embodiments, the first information may indicate the at least one event corresponding to which event is triggered. For example, the first information (or the pre-notification codebook) may indicate the at least one event corresponding to which event (s) and / or cell (s) is triggered.
[0170] In some embodiments, the at least one DCI (e.g. in one monitoring occasion or in the second group of occasions or in the second group of slots or in the at least one PDCCH monitoring occasion) may include a first field indicating a transmission of the at least one measurement report on the second uplink channel. In some embodiments, the second uplink channel may be a physical uplink control channel (PUCCH) resource for hybrid automatic repeat request (HARQ) -ACK transmission with HARQ-ACK information corresponding to at least one physical downlink shared channel (PDSCH) scheduled by the DCI or corresponding to the at least one DCI. For example, the at least one DCI (e.g. in one monitoring occasion or in the second group of occasions or in the second group of slots or in the at least one PDCCH monitoring occasion) may comprise a first field (e.g. 1-bit field) indicating transmission of the at least one measurement report on the second uplink channel, wherein the second uplink channel may be the PUCCH resource for HARQ-ACK transmission with HARQ-ACK information corresponding to the PDSCH scheduled by the DCI (if the DCI with data / DL assignment) or corresponding to the DCI (if the DCI without data / DL assignment) . In some embodiments, the at least one measurement report may be appended to the HARQ-ACK information bits in the PUCCH resource. In some embodiments, the at least one second DCI may not comprise the first field.
[0171] In some embodiments, if the HARQ-ACK information on the PUCCH resource corresponds to more than one DCI with the notifying or confirming transmission of the at least one measurement report, only one payload for the at least one measurement report is appended to the HARQ-ACK information. For example, at least one bit of the HARQ-ACK information bits is positive (e.g. ACK) and / or at least one bit of the HARQ-ACK information bits corresponding to the DCI comprising the first field (with notifying or confirming the transmission of the at least one measurement report) is positive (e.g. ACK) . In some embodiments, the more than one DCI indicate notifying (or confirming) the at least one measurement report associated with a same set of events (and / or same set of cells) (e.g. the second set or the third set) or associated with a same occasion of the first uplink channel. In some embodiments, ifthere is more than one set of events (and / or more than one set of cells) associated with the transmission of the at least one measurement report on the PUCCH resource, the at least one measurement report is associated with the set of events (and / or set of cells) associated with the last DCI in time corresponding to the positive HARQ-ACK value.
