It can be transmitted to the electronic device 101 through the CIS 204.

For example, the second CIS 205 may be used to transmit at least one packet from the electronic device 101 to the second external electronic device 202 . For example, the at least one packet may be used to output audio being reproduced in the electronic device 101 through a speaker of the second external electronic device 202 . For example, the audio output through the speaker of the first external electronic device 201 and the audio output through the speaker of the second external electronic device 202 may provide stereophonic sound. However, it is not limited thereto. For example, the second CIS 205 transmits an acknowledgment signal for the at least one packet or a non-acknowledgement signal for the at least one packet to the second external electronic device 202. It can be used to transmit from to the electronic device 101.

Referring to FIG. 3 , the electronic device 101 may include a processor 120, a memory 130, and a communication circuit 190.

In one embodiment, the processor 120 may include the processor 120 in FIG. 1 . In one embodiment, memory 130 may include memory 130 in FIG. 1 . In one embodiment, the communication circuitry 190 connects an external electronic device (eg, the first external electronic device 201 or the second external electronic device 202 shown in FIG. 2 ) via the first network 198 . It may include a communication module 190 in FIG. 1 used to communicate with.

The processor 120 in the electronic device 101 uses the first external electronic device 201 to transmit data or at least one packet to each of the first external electronic device 201 and the second external electronic device 202. A first CIS event for the first CIS (eg, an event of the first CIS 204 shown in FIG. 2 ) and a second CIS event for the second external electronic device 202 (eg, the second CIS event shown in FIG. 2 ). A CIG event (eg, an event of CIG 203 shown in FIG. 2) including an event of CIS 205 may be acquired, configured, or set. For example, the CIG event including the first CIS event and the second CIS event starts at the start timing of the first sub-event of the first scheduled CIS and the last sub-event within the ISO interval. It can end at the end timing. For example, the anchor point of the CIG event may occur simultaneously with the anchor point of the first CIS event in the CIG event.

For example, each of the first CIS event and the second CIS event may consist of one or more subevents. For example, the sub-event in the first CIS event includes transmission of a packet from the electronic device 101 and a response packet from the first external electronic device 201 (eg, the confirmation signal defined through the description of FIG. 2 ). Alternatively, it may be used for transmission of the unidentified signal defined through the description of FIG. 2). For example, sub-events in the second CIS event may be used for transmission of packets from the electronic device 101 and transmission of response packets from the second external electronic device 202 .

For example, each of the first CIS event and the second CIS event may be scheduled in a sequential arrangement or in an interleaved arrangement within the CIG event. For example, referring to FIG. 4A , as shown in a timing diagram 400 , the processor 120 performs a first CIS event including a first sub-event 404 and a second sub-event 405 . 402, and a second CIS event 403 including a first sub-event 406 and a second sub-event 407 can be scheduled within the CIG event 401 in the sequential arrangement. For example, as shown in timing diagram 400 , processor 120 schedules first CIS event 402 and second CIS event 403 immediately after first CIS event 402 . A CIG event 401 including the second CIS event 403 in the sequential arrangement may be obtained, configured, or set. Since the first CIS event 402 and the second CIS event 403 are scheduled back-to-back in the sequential arrangement, the first CIS event 402 and the second CIS event 402 in the sequential arrangement Events 403 do not overlap each other. For another example, referring to FIG. 4B , as shown in the timing diagram 450 , the processor 120 generates a first CIS event 402 including a first sub-event 404 and a second sub-event 405 . and a second CIS event 403 including the first sub-event 406 and the second sub-event 407 can be scheduled within the CIG event 401 in the interleaved arrangement. For example, as shown in timing diagram 450 , the processor 120 may generate a first sub-event 406 in a second CIS event 403 immediately after a first sub-event 404 in a first CIS event 402 . and schedules a second sub-event 405 in the first CIS event 402 immediately after the first sub-event 406 in the second CIS event 403 and a second sub-event in the first CIS event 402 By scheduling the second sub-event 407 in the second CIS event 403 immediately after (405), the CIG event 401 including the first CIS event 402 and the second CIS event 403 in the interleaved arrangement. ) can be acquired, configured, or set. For example, within the timing diagram 450, the first CIS event 402 starts at the start timing of the first sub-event 404 and ends at the end timing of the second sub-event 405, but 406, the second CIS event 403 starts at the start timing of the first sub-event 406 and ends at the end timing of the second sub-event 407, but does not include the sub-event 405. Therefore, within the interleaved arrangement, the first CIS event 402 and the second CIS event 403 do not overlap with each other. Meanwhile, in each of the sequential arrangement and the interleaved arrangement, the processor 120 processes a first sub-event 404, a second sub-event 405, a first sub-event 406, and a second sub-event 407. Since the packet can be transmitted once through each, the processor 120 transmits the packet to the first external electronic device 201 through the first CIS event 402 in each of the sequential arrangement and the interleaved arrangement. can be transmitted at most twice and can be transmitted to the second external electronic device 202 through the second CIS event 403 at most twice. In other words, within each of the sequential batch and the interleaved batch, the opportunity to transmit a packet through the first CIS event 402 is fixed and the opportunity to transmit a packet through the second CIS event 403 is fixed. For example, in each of the sequential arrangement and the interleaved arrangement, the processor 120 determines the quality of the first link between the first external electronic device 201 and the electronic device 101 and the second external electronic device 202 The number of packets transmitted through the first CIS event 402 and the number of packets transmitted through the second CIS event 403 may be adaptively changed according to the quality of the second link between the device and the electronic device 101. does not exist.

Referring back to FIG. 3 , the processor 120, in order to adaptively change the number of packet transmissions through the first CIS event and the number of packet transmissions through the second CIS event, the first CIS The CIG event may be acquired, configured, or set by scheduling the second CIS event overlapping at least part of the event with at least partially. For example, the processor 120 schedules an anchor point of the second CIS event within the first CIS event, so that the first CIS event and at least a part of the first CIS event overlap at least a portion of the second CIS event. The CIG event including the CIS event may be acquired. For example, the processor 120 obtains the CIG event including the first CIS event and the second CIS event including sub-events that at least partially overlap with at least some of the sub-events in the first CIS event. can do. Overlapping at least a portion of the first CIS event with at least a portion of the second CIS event may be referred to as a hybrid arrangement in that it has characteristics of both the sequential arrangement and the interleaved arrangement. there is.

Meanwhile, the processor 120 may schedule the first CIS event and the second CIS event within the CIG event in the hybrid arrangement based on satisfying a specified condition.

For example, the processor 120, based on identifying that at least one external electronic device (eg, the first external electronic device 201 and the second external electronic device 202) supports the hybrid arrangement, With the hybrid arrangement, the first CIS event and the second CIS event may be scheduled within the CIG event. For example, the processor 120, based on identifying data indicating that the hybrid arrangement is supported from capability information of the at least one external electronic device received from the at least one external electronic device, determines the hybrid arrangement. The first CIS event and the second CIS event may be scheduled within the CIG event. For example, the processor 120 determines that the modulation scheme of the signal received from the at least one external electronic device supports the hybrid configuration, and determines that the hybrid configuration supports the first hybrid configuration. A CIS event and the second CIS event may be scheduled within the CIG event.

For example, the processor 120 may perform the first CIS event on a condition that anchor points of at least some of the sub-events in the first CIS event correspond to anchor points of at least some of the sub-events in the second CIS event. The CIG event including the second CIS event including the sub-events overlapping at least in part with at least some of the sub-events in the CIS event may be obtained. For example, the processor 120 may determine an anchor point of a first sub-event of the sub-events in the first CIS event and a second sub-event immediately following the first of the sub-events in the first CIS event. The time interval between the anchor points of events is the anchor point of the third sub-event of the sub-events in the second CIS event and the fourth sub-event immediately after the third of the sub-events in the second CIS event. The CIG including the second CIS event including the sub-events overlapping at least in part with the at least some of the sub-events in the first CIS event, under the condition that the time interval between anchor points of event can be obtained. For example, the processor 120 determines between an anchor point of the third sub-event among the sub-events in the second CIS event and an anchor point of the fourth sub-event in the second CIS event. A time interval of is a multiple of the time interval between an anchor point of the first sub-event of the sub-events in the first CIS event and an anchor point of the second sub-event of the sub-events in the first CIS event. Conditionally, the CIG event including the second CIS event including the sub-events overlapping at least in part with at least some of the sub-events in the first CIS event may be obtained. For example, the processor 120 determines whether the length of each of the sub-events in the first CIS event is a multiple of the length of each of the sub-events in the second CIS event or the sub-events in the second CIS event. The second including the sub-events overlapping at least in part with the at least some of the sub-events in the first CIS event on the condition that each length is a multiple of the length of each of the sub-events in the first CIS event. The CIG event including the CIS event may be acquired. For example, the processor 120 may perform the first CIS event and the second CIS event under the condition that the length of each of the sub-events in the first CIS event is equal to the length of each of the sub-events in the second CIS events. The CIG event including the second CIS event including at least some of the sub-events in the first CIS event and at least some overlapping sub-events may be obtained.

For example, referring to FIG. 5A , as shown in the timing diagram 500 , the processor 120 performs a first CIS event 502 and a part of the first CIS event 502 partially overlaps with the first CIS event 502 . A CIG event 501 including the second CIS event 503 may be set or obtained. For example, the processor 120 determines that each of the k-th sub-event 502-k (k is a natural number greater than 1 and less than n) to the n-th sub-event 502-n within the first CIS event 502 is The 1st CIS event 502 and the 2nd CIS event 502 overlap with each of the 1st sub-event 503-1 to the n-k+1 th sub-event 503-(n-k+1) in the 2 CIS event 503. By scheduling the CIS event 503, the CIG event 501 can be set or obtained. The first CIS event 502 is the k-th sub-event 502-k overlapped with the first sub-event 503-1 to the n-k+1-th sub-event 503-(n-k+1), respectively. ) to the n-th sub-event 502-n and the first sub-event 502-1 to the k-1-th sub-event 502-(k-1) that do not overlap with the second CIS event 503. Since it includes, the number of times that packets can be transmitted through the first CIS event 502 may be k-1 times to n times. In the timing diagram 500, the second CIS event 503 includes first sub-events 503-1 to 503-1 overlapped with the k-th sub-event 502-k to n-th sub-event 502-n, respectively. The n-k+1th sub-event 503-(n-k+1) and the n-k+2-th sub-event 503-(n-k+2) that do not overlap with the first CIS event 502 ) to nth sub-events 503-n, the number of times packets can be transmitted through the second CIS event 503 may be k-1 to n times. For example, the processor 120 determines the time interval of the first CIS event 502 that does not overlap with the second CIS event 503 (eg, the first sub-event 502-1 to the k-1th sub-event). A first CIS event 502 that transmits a packet 505 for the first external electronic device 201 through at least a part of (502-(k-1))) and overlaps with the second CIS event 503 (eg, the k-th sub-event 502-k to the n-th sub-event 502-n) (or the time interval of the second CIS event 503 overlapping with the first CIS event 502 (eg, : Packet 505 for the first external electronic device 201 through at least a part of the first sub-event 503-1 to the n-k+1th sub-event 503-(n-k+1) and a second packet 506 for the second external electronic device 202 may be transmitted, and the time interval of the second CIS event 503 that does not overlap with the first CIS event 502 (eg, the first CIS event 502). The packet 506 for the second external electronic device 202 is transmitted through at least a part of the n-k+2 sub-event 503-(n-k+2) to the n-th sub-event 503-n). For example, the processor 120 transmits the last target packet transmitted to the first external electronic device 201 through the first CIS event 502 through the k-th sub-event 502-k. 1 is transmitted to the external electronic device 201 and based on receiving the confirmation signal for the last target packet from the first external electronic device 201 through the k th sub-event 502-k, the second sub-event ( The packet 506 is transmitted to the second external electronic device 202 through each of the 503-2) to the n-k+1th sub-event 503-(n-k+1), and the sub-event 502-( It is possible to stop transmitting the packet 505 to the first external electronic device 201 through k+1) to sub-event 502-n. Here, the last target packet is the first CIS event ( 502) It may refer to a packet transmitted last among target packets scheduled to be transmitted to the first external electronic device 201 within the first CIS event 502 based on a burst number (BN) and a flush timeout (FT). there is. In other words, the processor 120 obtains the CIG event 501 including the first CIS event 502 and the second CIS event 503 partially overlapped with a part of the first CIS event 502, thereby obtaining the CIG event 501. The number of packets transmitted to the first external electronic device 201 through the event 501 and the number of packets transmitted to the second external electronic device 202 through the CIG event 501 may be adaptively changed. For example, the quality of the first link between the first external electronic device 201 and the electronic device 101 is much better than the quality of the second link between the second external electronic device 202 and the electronic device 101. (much better), the processor 120 transmits a packet to the second external electronic device 202 through a time interval of the second CIS event 503 partially overlapped with a part of the first CIS event 502. By allocating time intervals, the quality of multi-stream audio can be enhanced.

5A shows that the length of each of the first sub-event 502-1 to n-th sub-event 502-n in the first CIS event 502 is the first sub-event 503-1 in the second CIS event 503. ) to the n-th sub-event 503-n, but this is for convenience of description. For example, although not shown in FIG. 5A , the length of each of the first sub-event 502-1 to the n-th sub-event 502-n in the first CIS event 502 and the second CIS event 503 Even if the lengths of the first sub-event 503-1 to the n-th sub-event 503-n in the first CIS event 502 are different from each other, the first sub-event 502-1 to the n-th sub-event 502-1 to the n-th sub-event in the first CIS event 502 are different. Each of the anchor points of at least a part of (eg, the k-th sub-event 502-k to the n-th sub-event 502-n) of (502-n) is the first sub-event ( 503-1) to at least part of the n-th sub-event 503-n (eg, the first sub-event 503-1 to the n-k+1-th sub-event 503-(n-k+1)) On a condition corresponding to each of the anchor points of , the processor 120 includes a first CIS event 502 and a second CIS event 503 overlapping at least a portion of the first CIS event 502. CIG event 501 can be obtained. For example, although not shown in FIG. 5A , the interval between anchor points of the first sub-event 502-1 to n-th sub-event 502-n in the first CIS event 502 is the second CIS is a multiple of the interval between the anchor points of the first sub-event 503-1 to the n-th sub-event 503-n in the event 503, and the first sub-event 502-1 in the first CIS event 502 1) to the n-th sub-event 502-n, the offset of each anchor point is the anchor point of each of the 1st sub-event 503-1 to n-th sub-event 503-n in the second CIS event 503 On the condition that matches the offset of the CIG event ( 501) can be obtained. For example, although not shown in FIG. 5A , the interval between anchor points of the first sub-event 503-1 to the n-th sub-event 503-n in the second CIS event 503 is the first CIS is a multiple of the interval between the anchor points of the first sub-event 502-1 to the n-th sub-event 502-n in the event 502, and the first sub-event 502-1 in the first CIS event 502 1) to the n-th sub-event 502-n, the offset of each anchor point is the anchor point of each of the 1st sub-event 503-1 to n-th sub-event 503-n in the second CIS event 503 On the condition that matches the offset of the CIG event ( 501) can be obtained.

For example, referring to FIG. 5B , as shown in the timing diagram 550, the processor 120 generates a first CIS event 552 and a second CIS event 553 completely overlapped with the first CIS event 552. A CIG event 551 including can be obtained. For example, the processor 120 determines that each of the first sub-event 552-1 to the fourth sub-event 552-4 in the first CIS event 552 is the first sub-event in the second CIS event 553. The CIG event 551 may be obtained by scheduling the first CIS event 552 and the second CIS event 553 to overlap each of the events 553-1 to 4th sub-events 553-4. Since the first CIS event 552 and the second CIS event 553 completely overlap within the CIG event 551, the number of times the processor 120 can transmit a packet through the first CIS event 552 And through the second CIS event 553, the number of times packets can be transmitted can be adaptively changed. For example, the processor 120 transmits the last target packet transmitted to the first external electronic device 201 through the first CIS event 552 to the first external electronic device through the first sub-event 552-1. 201 and receiving the acknowledgment signal for the last target packet from the first external electronic device 201 through the first sub-event 552-1, the remainder of the first CIS event 552 The packet transmission to the first external electronic device 201 is stopped through the second sub-event 552-2 to the fourth sub-event 552-4, which are sub-events, and the second sub-event 553-2 A packet may be transmitted to the second external electronic device 202 through at least some of the through fourth sub-events 553-4. In other words, the processor 120 determines the time interval for transmitting the packet for the first external electronic device 201 and the second external electronic device according to the difference between the quality of the first link and the quality of the second link. By adaptively changing the time period for transmitting packets for the device 202 within the CIG event 551, the quality of multi-stream audio can be enhanced.

5B shows that the length of each of the first sub-event 552-1 to the fourth sub-event 552-4 in the first CIS event 552 is the first sub-event 553-1 in the second CIS event 553. ) to the fourth sub-event 553-4, the same example is shown, but this is for convenience of description. For example, although not shown in FIG. 5B , the length of each of the first sub-event 552-1 to the fourth sub-event 552-4 in the first CIS event 552 and the second CIS event 553 Even if the lengths of the first sub-event 553-1 to the fourth sub-event 553-4 in the first CIS event 552 are different from each other, the first sub-event 552-1 to the fourth sub-event 552-1 to the fourth sub-event in the first CIS event 552 (552-4) Under the condition that each anchor point corresponds to each anchor point of the first sub-event 553-1 to the fourth sub-event 553-4 in the second CIS event 553, the processor 120 ) may obtain a CIG event 551 including a first CIS event 552 and a second CIS event 553 overlapping the first CIS event 552 . For example, although not shown in FIG. 5B , the interval between anchor points of the first sub-event 552-1 to the fourth sub-event 552-4 in the first CIS event 552 is the second CIS is a multiple of the interval between the anchor points of the first sub-event 553-1 to the fourth sub-event 553-4 in the event 553, and the first sub-event 552-1 in the first CIS event 552 Offsets of anchor points of 1) to 4th sub-event 552-4 are anchor points of 1st sub-event 553-1 to 4th sub-event 553-4 in the 2nd CIS event 553 On a condition matching each of the offsets, the processor 120 generates a CIG event 551 including a first CIS event 552 and a second CIS event 553 overlapping the first CIS event 552. can be obtained For example, this CIG event 551 will be illustrated through the description of FIG. 5C.

For example, although not shown in FIG. 5B , the interval between anchor points of the first sub-event 553-1 to the fourth sub-event 553-4 in the second CIS event 553 is is a multiple of the interval between the anchor points of the first sub-event 552-1 to the fourth sub-event 552-4 in the event 552, and the first sub-event 552-1 in the first CIS event 552 Offsets of anchor points of 1) to 4th sub-event 552-4 are anchor points of 1st sub-event 553-1 to 4th sub-event 553-4 in the 2nd CIS event 553 On a condition matching each of the offsets, the processor 120 generates a CIG event 551 including a first CIS event 552 and a second CIS event 553 overlapping the first CIS event 552. can be obtained

For example, referring to FIG. 5C , as shown in timing diagram 570, a first CIS event 572 and a second CIS event 573 completely overlapped with the first CIS event 572 are included. A CIG event 571 may be obtained. For example, the processor 120 determines that the first sub-event 572-1 of the first CIS event 572 is the first sub-event 573-1 and the second sub-event 573-1 of the second CIS event 573. 573-2, and the second sub-event 572-2 of the first CIS event 572 is the third sub-event 573-3 of the second CIS event 573 and the fourth sub-event ( 573-4), and the third sub-event 572-3 of the first CIS event 572 is the fifth sub-event 573-5 and the sixth sub-event 573 of the second CIS event 573. -6), and the fourth sub-event 572-4 of the first CIS event 572 corresponds to the seventh sub-event 573-7 and the eighth sub-event 573-4 of the second CIS event 573. 8), the CIG event 571 can be obtained by scheduling the first CIS event 572 and the second CIS event 573 to overlap. For example, unlike the CIG event 501 and CIG event 551 shown in FIGS. 5A and 5B , the number of sub-events of the first CIS event 572 of the CIG event 571 is the CIG event ( 571) may be different from the number of sub-events of the second CIS event 573. For example, the interval between the anchor points of the sub-events of the first CIS event 572 of the CIG event 571 is CIG event 501 and CIG event 551 shown in FIGS. 5A and 5B , respectively. ), it may be longer than the interval between anchor points of the sub-events of the second CIS event 573 of the CIG event 571. For example, unlike the CIG event 501 and CIG event 551 shown in FIGS. 5A and 5B , the number of times a packet can be transmitted through the first CIS event 572 is the second CIS event ( 573) may be different from the number of times packets can be transmitted. For example, the interval between the anchor points of the sub-events of the first CIS event 572 of the CIG event 571 is the number of sub-events of the second CIS event 573 of the CIG event 571. It may be a multiple of the interval between the anchor points. For example, the offset of each anchor point of the sub-events of the first CIS event 572 of the CIG event 571 is the offset of each of the sub-events of the second CIS event 573 of the CIG event 571. It may be the same as the offset of the anchor point. For example, the position of the anchor point of the first sub-event 572-1 of the first CIS event 572 is the position of the anchor point of the first sub-event 573-1 of the second CIS event 573. , and the position of the anchor point of the second sub-event 572-2 of the first CIS event 572 is the position of the anchor point of the third sub-event 573-3 of the second CIS event 573. , and the position of the anchor point of the third sub-event 572-3 of the first CIS event 572 is the position of the anchor point of the fifth sub-event 573-5 of the second CIS event 573. , and the position of the anchor point of the fourth sub-event 572-4 of the first CIS event 572 is the position of the anchor point of the seventh sub-event 573-7 of the second CIS event 573. can be the same as For example, the anchor point of the second sub-event 573-2 of the second CIS event 573 is within the first sub-event 572-1 of the first CIS event 572, and the second CIS event ( The anchor point of the fourth sub-event 573-4 of 573) is within the second sub-event 572-2 of the first CIS event 572, and the sixth sub-event 573 of the second CIS event 573 -6) is within the third sub-event 572-3 of the first CIS event 572, and the anchor point of the eighth sub-event 573-8 of the second CIS event 573 is within the first CIS event 572. It may be within the fourth sub-event 572-4 of the CIS event 572. For example, the sub-events of the first CIS event 572 may be synchronized with the sub-events of the second CIS event 573 .

For example, the interval between the anchor points of the sub-events of the first CIS event 572 within the time interval for CIG event 571 is the sub-event of the second CIS event 573 within the time interval. Since it is longer than the interval between the anchor points of , the time interval is transmitted to the first external electronic device 201 and transmitted to the second external electronic device 202 for each sub-event of the first CIS event 572. It may be a time interval in which transmission of one (a) of the transmission can be adaptively selected.

Referring back to FIG. 3 , the processor 120 provides time resources provided for the first CIS event and time resources provided for the second CIS event at least partially overlapping with at least a portion of the first CIS event. In order to uniformly distribute them, the first CIS event in the CIG event including the first CIS event and the second CIS event (eg, the first CIS event among the first CIS event and the second CIS event) can be changed adaptively. For example, processor 120 may determine that an anchor point of the first CIS event in a first CIG event coincides with an anchor point of the first CIG event and an anchor point of the second CIS event in the first CIG event. scheduling the first CIS event in the first CIG event and the second CIS event in the first CIG event to occur before, and an anchor point of the first CIS event in a second CIG event immediately after the first CIG event; The first CIS event in the second CIG event and the first CIS event in the second CIG event such that occur simultaneously with the anchor point of the second CIG event and before the anchor point of the second CIS event in the second CIG event. 2 CIS events can be scheduled. For example, the processor 120 allocates a first CIS event in a 2k-1 (k is a natural number equal to or greater than 1) CIG event as the first CIS event, and allocates a first CIS event in a 2k-th CIG event to the second CIS event. By allocating them as events, time resources provided for the first CIS event and time resources provided for the second CIS event at least partially overlapping with at least a portion of the first CIS event can be uniformly distributed. can For example, referring to FIG. 6 , as shown in the timing diagram 600, the processor 120 converts a CIS event starting from an anchor point 605 of a kth CIG event 601-k to a first CIS event. 602 and the second CIS event 603 partially overlapped with a part of the first CIS event 602, the first CIS event 602 is scheduled, and the k-th immediately after the k-th CIG event 601-k. A CIS event starting at the anchor point 607 of the +1 CIG event 601-(k+1) is a second CIS event partially overlapped with a first CIS event 602 and a part of the first CIS event 602. Among the events 603, the second CIS event 603 can be scheduled.

Referring back to FIG. 3, attributes of data in a packet that can be transmitted through the first CIS event, which is the first CIS event in the CIG event, are at least partially overlapped with at least a portion of the first CIS event. It may correspond to attributes of data included in packets that may be transmitted through events. The processor 120 obtains first CIS events for first packets to be transmitted to the first external electronic device 201, respectively correspond to the first packets, and are related to the first external electronic device 201. A second CIS event for second packets to be transmitted to the second external electronic device 202 may be acquired. For example, since the first packets correspond to the second packets, the processor 120 determines the first CIS event and the second CIS event overlapping at least a portion of the first CIS event. Through this, the first packets and the second packets may be transmitted in various ways.

For example, the processor 120 transmits the second packets to the second CIS event on a condition that transmission of the first packets is completed through at least a part of the first CIS event that is the first CIS event in the CIG event. It can be transmitted through at least a part of. For example, the scheduling of transmitting the second packets after completing the transmission of the first packets is different from transmitting the first packets and the second packets using the sequential arrangement. Since the number of sub-events in the first CIS event used for transmission of packets and the number of sub-events in the second CIS event used for transmission of the second packets can be varied, the hybrid arrangement Transmitting the second packets after completing transmission of 1 packets may provide a more enhanced service than transmitting the first packets and the second packets using the sequential arrangement.

For example, referring to FIG. 7A , the processor 120 sends first packets (first After completing the transmission of the packets 713-1, 1st packet 713-2, and 1st packet 713-3, the second CIS event 711 overlaps with at least a portion of the first CIS event 711. Second packets may be transmitted to the second external electronic device 202 through at least a part of the CIS event 712 . In this case, the number of sub-events in the second CIS event 712 available for transmitting the second packets may change depending on when the transmission of the first packets is completed. For example, as shown in the timing diagram 700, when the first packet 713-3 is retransmitted differently from the first packet 713-1 and the first packet 713-2, the processor 120, The second packets are transmitted to the second external electronic device 202 through a portion 714 of the second CIS event 712 including four sub-events, and the first packet 713-1 and the first packet When the transmission of the first packets including 713-2 and the first packet 713-3 is completed without retransmission, the processor 120 generates a second CIS event 712 including 5 sub-events. The second packets may be transmitted to the second external electronic device 202 through a part 715 of ). For example, unlike the sequential arrangement, since the hybrid arrangement can change transmission opportunities, the hybrid arrangement can provide more adaptive transmission opportunities than the sequential arrangement.

For example, the processor 120 alternately transmits the first packets and the second packets, and the condition that (a) transmission of one of the transmission of the first packets and the transmission of the second packets is completed On top of that, you can continue to send other transmissions. For example, since such transmission scheduling includes alternating transmission as well as continuous transmission, transmitting the first packets and the second packets in the hybrid arrangement may cause the first packets to be transmitted using the interleaved arrangement. And it can provide an enhanced service than transmitting the second packets.

For example, referring to FIG. 7A , the processor 120 determines a first CIS event 721 in a CIG event 720 and a second CIS event in a CIG event 720 overlapped with the first CIS event 721 . Using 722, first packets (eg, first packet 723-1, first packet 723-2, and first packet 723-3) to the first external electronic device 201 ) and transmission of second packets (eg, second packet 724-1, second packet 724-2, and second packet 724-3) to the second external electronic device 202. can be executed alternately in units of sub-events. For example, as shown in the timing diagram 702, the processor 120 transmits the first packet 723-1 to the first external electronic device 201 through the first CIS event 721 and then sends the second packet 723-1 to the first external electronic device 201. The second packet 724-1 is transmitted to the external electronic device 202 through the second CIS event 722, and after the second packet 724-1 is transmitted, the second packet 724-1 is transmitted to the first external electronic device 201. The first packet 723-2 is transmitted through the 1 CIS event 721, and after the first packet 723-2 is transmitted, the second CIS event 722 is sent to the second external electronic device 202. The second packet 724-1 may be retransmitted through the second packet 724-1, and after the second packet 724-1 is retransmitted, the first packet 723-3 may be transmitted to the first external electronic device 201. For example, the processor 120 may perform a second CIS event (including three sub-events) on the condition that transmission of the first packet 723-3 succeeds and retransmission of the second packet 724-1 succeeds. The second packet 724 - 2 and the second packet 724 - 3 may be transmitted to the second external electronic device 202 through the part 725 of 722 . For example, despite completion of transmission of the first packets, a second packet 724-2 is transmitted through two sub-events due to a sub-event (eg, sub-event 726) in the first CIS event 721. and the second packet 724-3, unlike the interleaved arrangement, in the hybrid arrangement, the second packet 724 is transmitted through a part 725 of the second CIS event 722 including three sub-events. -2) and the second packet 724-3 may be transmitted. For example, the hybrid arrangement may provide more adaptive transmission opportunities than the interleaved arrangement.

Referring back to FIG. 3, attributes of data in a packet that can be transmitted through the first CIS event, which is the first CIS event in the CIG event, are at least partially overlapped with at least a portion of the first CIS event. It can be distinguished from the attributes of data contained within packets that can be transmitted through events. For example, when both the first CIS event and the second CIS event are acquired, set, or scheduled for packets to be transmitted to an external electronic device, the processor 120 ) to the external electronic device through the first CIS event that starts prior to the second CIS event, and transmits a packet including data obtained based on identifying a specified event. It can be transmitted to the external electronic device through the second CIS event. For example, the size of a buffer for data transmitted through the first CIS event may be larger than the size of a buffer for data transmitted through the second CIS event. However, it is not limited thereto. For example, the processor 120 transmits a packet for audio continuously provided through the first CIS event starting before the start timing of the second CIS event, and specified through the second CIS event. A packet may be transmitted for audio provided conditional on the identification of the event.

For example, referring to FIG. 7B , the processor 120 displays a user interface 730 of a game executed in the electronic device 101 on a display of the electronic device 101 (eg, the display shown in FIG. 1 ). module 160). For example, while displaying the user interface 730, the processor 120 provides background music (BGM) of the game and sound effects provided based on user input received through the user interface 730. As shown in the timing diagram 740, the first CIS event 751 and a part of the first CIS event 751 and a part of the second CIS event 752 are overlapped in order to output P using the external electronic device 735. A first CIG event 750 including a is obtained, and a second CIG event including a first CIS event 761 and a second CIS event 762 partially overlapped with a part of the first CIS event 761 ( 760) can be obtained. For example, the processor 120 transmits the packet 770 for the BGM, which is continuously output while the game is running, to each of the first CIG event 750 and the second CIG event 760, which are first CIS events. The packet 771 for the sound effect, which is transmitted to the external electronic device 735 through each of the first CIS event 751 and the first CIS event 761 and receives the user input, is transmitted to the second It can be transmitted to the external electronic device 735 through each of the CIS event 752 and the second CIS event 762 . For example, if the user input causing the sound effect is not received during the first CIG event 750, the processor 120, as shown in the timing diagram 740, The packet 770 is transmitted to the external electronic device 735 through the CIS event 751, and no packet is transmitted through the second CIS event 752 in the first CIG event 750 or the first CIG event ( A dummy packet 772 may be transmitted through the second CIS event 752 in 750 . For another example, if a user input 780 causing the sound effect is received during the second CIG event 760, the processor 120, as shown in the timing diagram 740, within the second CIG event 760. The packet 770 is transmitted to the external electronic device 735 through a part of the first CIS event 761, and the second CIS event in the second CIG event 760 overlapped with the part of the first CIS event 761 A packet 771 may be transmitted to the external electronic device 735 through a part of 762 . For example, the priority of the packet 771 related to the user input 780 may be higher than the priority of the packet 770 . For example, processor 120 may, in response to receiving user input 780, even if transmission of packet 770 is not completed via part of first CIS event 761, first CIS event 761 The packet 771 may be transmitted through a portion of the second CIS event 762 overlapped with a portion of . In other words, the processor 120 allocates a plurality of CIS events for respectively transmitting packets having different priorities to a single external electronic device such as the external electronic device 735, completely or partially from each other. The plurality of CIS events may be scheduled to overlap.

8 is a flowchart illustrating a method of transmitting data through a CIG event including a first CIS event and a second CIS event in a hybrid arrangement according to an embodiment. This method is the electronic device 101 shown in FIG. 1, the electronic device 101 shown in FIG. 2, the electronic device 101 shown in FIG. 3, or the processor 120 of the electronic device 101. ) can be executed.

Referring to FIG. 8 , in operation 802, the processor 120 may obtain a CIG event including a first CIS event and a second CIS event overlapping at least a portion of the first CIS event. For example, the CIG event may include the first CIS event and the second CIS event in the hybrid arrangement. For example, the first CIS event is an event used to transmit data to a first external electronic device (eg, the first external electronic device 201 shown in FIG. 2), and the second CIS event is It may be an event used to transmit data to a second external electronic device (eg, the second external electronic device 202 shown in FIG. 2 ). For example, the first CIS event may include first sub-events, and the second CIS event may include second sub-events overlapping at least some of the first sub-events. For example, the processor 120 configures an anchor point of the second CIS event within the first CIS event starting from an anchor point of the first CIS event, so that the first sub-events include the first sub-events. The CIG event including a CIS event and the second CIS event including the second sub-events that at least partially overlap with at least some of the first sub-events may be obtained. However, it is not limited thereto.

In one embodiment, the processor 120 supports the first external electronic device and the second external electronic device to include the first CIS event and the second CIS event in the CIG event in the hybrid arrangement. Based on identifying , operation 802 may be performed. For example, the processor 120 is based on receiving capability information of the first external electronic device from the first external electronic device and capability information of the second external electronic device from the second external electronic device. Accordingly, it may be determined that the hybrid arrangement includes the first CIS event and the second CIS event in the CIG event, and operation 802 may be executed based on the determination. However, it is not limited thereto.

In operation 804, the processor 120 may transmit first data to the first external electronic device through a first sub-event in the first CIS event. For example, the first sub-event may be one of the first sub-events in the first CIS event. For example, the first sub-event may overlap with one of the second sub-events in the second CIS event, or may not overlap with all of the second sub-events. For example, when the first sub-event does not overlap with all of the second sub-events, a last sub-event among the second sub-events may not overlap with all of the first sub-events.

In operation 806, the processor 120 may receive an acknowledgment signal from the first external electronic device through the first sub-event in the first CIS event. For example, the first external electronic device sets NESN (nextExpectedSeqNum) in the packet to SN (transmitSeqNum) based on receiving a packet including the first data through the first sub-event, A response packet including the set SN may be transmitted to the electronic device 101 through the first sub-event as the confirmation signal. Based on receiving the confirmation signal, the processor 120 may identify that the first data is normally received from the first external electronic device through the first sub-event.

In operation 808, the processor 120 receives second data through a third sub-event in the second CIS event based on receiving the confirmation signal from the first external electronic device through the first sub-event. It can be transmitted to the second external electronic device. For example, the third sub-event in the second CIS event may include the second sub-events in the second CIS event overlapping with the second sub-event immediately following the first sub-event among the first sub-events. It may be one of (a) sub-events. For example, the third sub-event in the second CIS event may be a sub-event that initiates the second CIS event. However, it is not limited thereto. For example, the processor 120 transmits at least one packet including the second data to the second external electronic device through at least one sub-event including the third sub-event in the second CIS event. can be sent However, it is not limited thereto.

Meanwhile, although not shown in FIG. 8 , the processor 120 determines whether the first CIS event in the CIG event is based on receiving the confirmation signal from the first external electronic device through the first sub-event. Transmission of data to the first external electronic device may be stopped through all of the remaining sub-events.

As described above, the electronic device 101 configures the CIG event including the first CIS event and the second CIS event in the hybrid arrangement, so that the first external electronic device and the electronic device 101 are connected. A time resource for adaptively transmitting data to the first external electronic device according to a change in at least one of the state of the first link or the state of the second link between the second external electronic device and the electronic device 101 and time resources for transmitting data to the second external electronic device. For example, the electronic device 101 configures the CIG event including the first CIS event and the second CIS event in the hybrid arrangement and allocates the CIG event to each of the first CIS event and the second CIS event. You can increase the amount of time resources available.

9A illustrates the first sub-events in a first CIS event and synchronization of the anchor points of each of the second sub-events in a second CIS event in a hybrid arrangement, according to an embodiment. A flow chart illustrating a method of acquiring a CIS event and a CIG event including the second CIS event. This method is the electronic device 101 shown in FIG. 1, the electronic device 101 shown in FIG. 2, the electronic device 101 shown in FIG. 3, or the processor 120 of the electronic device 101. ) can be executed.

Operations 902 to 904 of FIG. 9A may be related to operation 802 of FIG. 8 .

Referring to FIG. 9A , in operation 902, the processor 120 determines that anchor points of each of the first sub-events in the first CIS event defined through the description of FIG. 8 are defined through the description of FIG. Whether the second sub-events in the second CIS event are synchronized with the respective anchor points may be identified. For example, if the anchor point of each of the first sub-events is synchronized with the anchor point of each of the second sub-events, the offset of the anchor point of each of the first sub-events is It may mean that the offset of each of the anchor points coincides with the anchor points of the first sub-events, and the interval between the anchor points of the first sub-events is a multiple of the interval between the anchor points of the second sub-events. For example, if the anchor point of each of the first sub-events is synchronized with the anchor point of each of the second sub-events, the offset of the anchor point of each of the first sub-events is coincides with the offset of the anchor point of each of the sub-events, and the interval between the anchor points of the second sub-events is a multiple of the interval between the anchor points of the first sub-events. For example, synchronization of the anchor point of each of the first sub-events with the anchor point of each of the second sub-events means that the length of each of the first sub-events and the length of each of the second sub-events are synchronized. Regardless of (or independently of), since it may mean that it is possible to perform scheduling so that at least some of the first sub-events and at least some of the second sub-events overlap, the processor 120 It may be identified whether the anchor point of each of the first sub-events is synchronized with the anchor point of each of the second sub-events. For example, the processor 120 executes operation 904 under the condition that the anchor point of each of the first sub-events is synchronized with the anchor point of each of the second sub-events, and Operation 906 may be executed on a condition that the anchor point of each of the second sub-events is not synchronized with the anchor point of each of the second sub-events.

In operation 904, the processor 120 determines the first CIS event and the second sub-event based on identifying that the anchor point of each of the first sub-events is synchronized with the anchor point of each of the second sub-events. The CIG event including the second CIS event that at least partially overlaps with at least a portion of the first CIS event may be obtained. For example, the processor 120 may obtain the CIG event including the first CIS event and the second CIS event in the hybrid arrangement.

In operation 906, the processor 120 performs sequential or interleaved arrangement based on identifying that the anchor point of each of the first sub-events is not synchronized with the anchor point of each of the second sub-events. The CIG event including the first CIS event and the second CIS event can be obtained with

9B illustrates the first CIS event and the first CIS event and the second sub-event in a hybrid arrangement based on the length of each of the first sub-events in the first CIS event and the length of each of the second sub-events in the second CIS event, according to an embodiment. A flowchart illustrating a method of obtaining a CIG event including a second CIS event. This method is the electronic device 101 shown in FIG. 1, the electronic device 101 shown in FIG. 2, the electronic device 101 shown in FIG. 3, or the processor 120 of the electronic device 101. ) can be executed.

Operations 912 to 914 of FIG. 9B may be related to operation 802 of FIG. 8 .

Referring to FIG. 9B , in operation 912, the processor 120 determines the length of each of the first sub-events in the first CIS event defined through the description of FIG. 8 . It is possible to identify whether the length is the same as the length of each of the second sub-events in the 2 CIS event. For example, the fact that the length of each of the first sub-events is equal to the length of each of the second sub-events means that at least some of the first sub-events overlap with at least some of the second sub-events. Since it may mean that it is possible to perform, the processor 120 may identify whether the length of each of the first sub-events is equal to the length of each of the second sub-events. For example, the processor 120 may include a parameter (eg, SE_length) of the first CIS event indicating the length of each of the first sub-events in the first CIS event and a parameter in the second CIS event. By identifying the parameter of the second CIS event indicating the length of each of the second sub-events, it may be identified whether the length of each of the first sub-events is equal to the length of each of the second sub-events. there is. Under the condition that the length of each of the first sub-events is equal to the length of each of the second sub-events, the processor 120 executes operation 914, wherein the length of each of the first sub-events is equal to the length of each of the second sub-events. On conditions other than the length of each of the events, processor 120 may execute operation 916 .

Although not shown in FIG. 9B , in operation 912, the processor 120 may further identify whether or not the start timing of each of the first sub-events is synchronized with the start timing of each of the second sub-events. For example, the length of each of the first sub-events may be the same as the length of each of the second sub-events, and the start timing of each of the first sub-events may be synchronized with the start timing of each of the second sub-events. Since it may mean that it is possible to perform scheduling so that at least some of the first sub-events overlap with at least some of the second sub-events, the processor 120 may determine whether each of the first sub-events A comparison between the length and the length of each of the second sub-events and a comparison between a start timing of each of the first sub-events and a start timing of each of the second sub-events may be performed. The processor 120 determines that the length of each of the first sub-events is equal to the length of each of the second sub-events, and the start timing of each of the first sub-events is the same as the start timing of each of the second sub-events. Operation 914 can be executed on conditions that can be synchronized, and operation 916 can be executed otherwise.

In operation 914, the processor 120 determines the first CIS event and the first CIS event based on identifying that the length of each of the first sub-events is equal to the length of each of the second sub-events. The CIG event including the second CIS event overlapping at least a part with at least a part of the CIG event may be obtained. For example, the processor 120 may obtain the CIG event including the first CIS event and the second CIS event in the hybrid arrangement.

In operation 916, the processor 120 sequentially or interleaved the first CIS events based on identifying that the length of each of the first sub-events is different from the length of each of the second sub-events. and the CIG event including the second CIS event.

10 is a flowchart illustrating a method of transmitting data within a time interval in which at least a portion of a first CIS event and at least a portion of a second CIS event overlap, according to an embodiment. This method is the electronic device 101 shown in FIG. 1, the electronic device 101 shown in FIG. 2, the electronic device 101 shown in FIG. 3, or the processor 120 of the electronic device 101. ) can be executed.

Operations 1002 and 1006 of FIG. 10 may be related to operation 808 of FIG. 8 .

10 , in operation 1002, after executing operation 806, the processor 120 transmits the first data transmitted through operation 804 to the first external electronic device through the first CIS event. It is possible to identify whether it is the last target data. For example, receiving the confirmation signal for the first data, which is the last target data, in operation 806 may mean that transmission of all data scheduled for the first CIS event is completed. When transmission of all data scheduled for the first CIS event is completed, since there is no need to transmit data through the second sub-event in the first CIS event immediately following the first sub-event, the processor 120 may identify whether the first data is the last target data. On the condition that the first data is the last target data, the processor 120 may execute operation 1004, and on the condition that the first data is not the last target data, the processor 120 may execute operation 1006. there is.

In operation 1004, the processor 120 performs the third sub-event in the second CIS event overlapping at least a portion with at least a portion of the first CIS event, based on identifying that the first data is the last target data. It is possible to transmit the second data through. For example, operation 1004 may correspond to operation 808 of FIG. 8 .

In operation 1006, the processor 120, based on identifying that the first data is not the last target data, selects another next to the first data through the second sub-event in the first CIS event. ) data can be transmitted.

As described above, when transmission of all data scheduled for the first CIS event is completed before the end of the first CIS event, the electronic device 101 replaces the remaining sub-events in the first CIS event with the remaining sub-events. Data may be transmitted to the second external electronic device through sub-events in the second CIS event overlapped with sub-events. In other words, the electronic device 101 uses the CIG event including the first CIS event and the second CIS event in the hybrid arrangement to transmit information to the second external electronic device through the second CIS event. The number of transmissions can be increased.

11 is a flowchart illustrating a method of obtaining a CIG event including a first CIS event and a second CIS event in a hybrid arrangement based on attributes of data, according to an embodiment. This method is the electronic device 101 shown in FIG. 1, the electronic device 101 shown in FIG. 2, the electronic device 101 shown in FIG. 3, or the processor 120 of the electronic device 101. ) can be executed.

Operations 1102 to 1104 of FIG. 11 may be related to operation 802 of FIG. 8 .

Referring to FIG. 11 , in operation 1102, the processor 120 may identify whether the first data or the second data is related to multimedia content. For example, the processor 120 determines the size of the first data to be transmitted through the first CIS event or the size of the second data to be transmitted through the second CIS event in the hybrid arrangement. In order to identify whether it is required to configure the CIG event including an event and the second CIS event, whether the first data or the second data is related to multimedia content may be identified. For another example, the processor 120 may determine the load of the first external electronic device for processing the first data to be transmitted through the first CIS event or the data to be transmitted through the second CIS event. To identify whether a load of the second external electronic device for processing second data requires configuring the CIG event including the first CIS event and the second CIS event in the hybrid arrangement, the It is possible to identify whether the first data or the second data is related to multimedia content. For another example, the processor 120 determines the quality of service (QoS) of the first data to be transmitted through the first CIS event or the QoS of the second data to be transmitted through the second CIS event. Identifying whether the first data or the second data is related to multimedia content, to identify whether configuring the CIG event including the first CIS event and the second CIS event in a hybrid arrangement is required. can do. As another example, the processor 120 may determine whether the first data or the second data is multimedia to identify whether multi-stream audio is provided through the first external electronic device and the second external electronic device. It can identify whether or not it is related to the content. However, it is not limited thereto.

The processor 120 executes operation 1104 on a condition that the first data or the second data is related to multimedia content, and performs an operation on a condition that the first data and the second data are not related to multimedia content. 1106 can be executed.

In operation 1104, the processor 120, based on identifying that the first data or the second data is related to multimedia content, at least partially overlaps the first CIS event and at least a portion of the first CIS event. The CIG event including the second CIS event may be obtained. For example, the processor 120 may obtain the CIG event including the first CIS event and the second CIS event in the hybrid arrangement.

In operation 1106, the processor 120, based on identifying that the first data and the second data are not related to multimedia content, in a sequential or interleaved arrangement, the first CIS event and the second CIS The CIG event including the event may be acquired. For example, when the sizes of the first data and the second data are relatively small, the processor 120 may obtain the CIG event in the sequential arrangement or the interleaved arrangement.
