Description

Method, apparatus and storage medium for determining timing relationship

Technical Field

The present application relates to the field of wireless communication technology, and in particular, to a method, apparatus, and storage medium for determining a timing relationship.

Background

In an NR (New Radio) air interface system, a physical downlink control channel (PDCCH, physical Downlink Control Channel) and a data channel scheduled by the PDCCH may or may not be transmitted in the same time unit.

This timing relationship between the PDCCH and its scheduled data channel is indicated by a particular value in a predetermined set of timing relationships. Data transmission generally needs to be prepared according to the minimum value in the set of timing relationships before signaling (e.g., PDCCH) indicating the particular value is received. The smaller the minimum value in the timing relation set, the higher the preparation requirement, the higher the processing intensity requirement of the UE, and the more electricity-consuming the UE, whereas the larger the minimum value in the timing relation set, the lower the preparation requirement, the lower the processing intensity requirement of the UE, the more power-saving the UE, the smaller the amount of data that can be transmitted and the larger the time delay of transmitting the data.

In view of this, a technical solution is needed that balances the contradiction between resource consumption at the UE and meeting the data transmission requirements.

The set of timing relationships to be used for the user equipment UE is determined, for example, based on the size of the amount of data to be transmitted by the UE and the data transmission delay requirements. In some examples, a set of timing relationships with a larger value may be selected when the data volume transmission is small and the data transmission latency requirement is low, and a set of timing relationships with a smaller value may be selected when the data volume transmission is large and the data transmission latency requirement is high. Of course, the technical solution of the embodiment of the present application is not limited thereto, and other rules related to the data size and the data transmission delay requirement are also possible, and even other indicators related to data transmission may be used, as long as the indicators can affect the resource (e.g. power) consumption at the user equipment.

Fig. 4 shows a schematic block diagram of a base station according to an embodiment of the application. As shown in fig. 4, the base station includes a timing relationship set selection module 410, a timing relationship set indication module 420, a timing relationship determination module 430, and a timing relationship indication module 440.

The timing relationship set selection module 410 is configured to select a set of timing relationships to be used for a User Equipment (UE) from a plurality of sets of timing relationships.

The technical scheme of the application will be described in detail below according to specific examples. It should be appreciated that the following detailed description is merely exemplary of the application and should not be taken as limiting the application.

And when the timing relation from PDCCH to PDSCH is determined according to the timing relation indicated by the timing relation field, and the timing relation from PDSCH to HARQ-ACK and/or the timing relation from PDCCH to PUSCH is determined, the timing relation set can be transformed according to the size of data volume transmission and the data transmission delay requirement. The values in the set of timing relationships may increase when the data volume transmission is small and the data transmission delay requirement is low, and may decrease when the data volume transmission is large and the data transmission delay requirement is high. Therefore, the power consumption of the user terminal can be reduced, and the requirements of data volume transmission and data transmission delay are met.

Based on this, as shown in fig. 5, a flowchart of a method for transforming a dynamic timing relation set is provided in the present application, and the method includes the following steps:

Step S501, receiving a timing relation set instruction and determining a used timing relation set;

step S502, determining a timing relationship based on the set of timing relationships used and the timing relationship indication.

Step S503, receiving or transmitting data or control information according to the determined timing relationship.

In the application, the timing relation set transformation comprises at least one of a timing relation set from PDCCH to PDSCH, a timing relation set from PDSCH to HARQ-ACK and a dynamic transformation method of the timing relation set from PDCCH to PUSCH.

The method for dynamically transforming the timing relation set provided by the application is based on the above, and the method is explained in detail below.

In this embodiment, a dynamic transform method of a PDCCH-PDSCH timing relation set is described, where the PDCCH-PDSCH timing relation set may be indicated by a field in the PDCCH of the scheduling PDSCH. Or the PDCCH-PDSCH timing relation set may be indicated by a field in the PDCCH of the non-scheduled PDSCH, that is, a dedicated PDCCH may indicate the PDCCH-PDSCH timing relation set transition, or the PDCCH-PDSCH timing relation set transition may be indicated by a reference signal, or the PDCCH-PDSCH timing relation set transition may be indicated in combination with other parameters requiring dynamic transition (e.g., the period of PDCCH monitoring, the bandwidth of PDCCH monitoring, the parameters such as the control resource set (control resource set)), for example, the PDCCH-PDSCH timing relation set transition and the PDCCH monitoring period transition indication combination, or the PDCCH-PDSCH timing relation set transition may be changed with the PDCCH monitoring period transition, the PDCCH listening period changes from p1 to p2, the PDCCH-PDSCH timing relation set changes from s1 to s2, or by limiting the PDCCH-PDSCH timing relation set, in practice different limits on the PDCCH-PDSCH timing relation set may be reached by PDCCH-PDSCH timing relation set changes, for example, set s1 includes { a1, a2, a3, a4, a5, a6, a7, a8}, set s2 includes { a3, a4, a5, a6, a7, a8, a9, a10}, set s1 and set s2 may be regarded as a result of different constraints of set s { a1, a2, a3, a4, a5, a6, a7, a8, a9, a10}, set changing from s1 to set s2 may be regarded as one constraint set of set s to another constraint set of set s. The constraint set is a new set formed after disabling some elements in a set, for example, set s1 may be considered as a set after disabling the ninth and tenth elements by set s, and set s2 may be considered as a set after disabling the first and second elements by set s. The application will be described below in terms of a set of timing relationships, and the constraint on the set of timing relationships may be applied.

The present application will be described below by taking, as an example, a shift of a set of timing relationships from PDCCH to PDSCH indicated by PDCCH. The multiple PDCCH-PDSCH timing relationship sets may be configured by the higher layer signaling, and then one of the multiple PDCCH-PDSCH timing relationship sets configured by the higher layer signaling is indicated by an indication information field in the PDCCH, e.g., the higher layer signaling configures 2 PDCCH-PDSCH timing relationship sets, set one being: {0,1,2,3}, set two is: {2,3,4,5}, whether the first set or the second set is used is indicated by 1 bit information in the PDCCH, for example, when the indication value is "0", the first set is used, and when the indication value is "1", the second set is used.

When the set of the timing relationships from PDCCH to PDSCH is set to be one, the minimum value in the set is {0} in {0,1,2,3}, the UE does not know which value in the set is indicated before receiving the PDCCH for scheduling PDSCH, the UE is to prepare according to the minimum value {0} in the set of the timing relationships, the PDCCH and PDSCH for scheduling PDSCH are buffered in one time unit, as shown in fig. 6, while the UE receives the PDCCH, the data signal on the PDSCH resource is likely to be transmitted, and the processing requirement for receiving the PDCCH is fast, so that the UE can receive data in time if the value {0} is indicated by the timing relationship indication information in the PDCCH.

And when the UE is prepared according to the minimum value {0} in the timing relation set, and the value indicated by the timing relation indication information in the actual PDCCH is greater than {0}, for example, equal to 1, the UE may discard the data buffering of the same time unit of the PDCCH, perform the data buffering in the next time unit, and can timely receive the data, as shown in fig. 7.

When the UE does not prepare according to the minimum value {0} in the timing relation set, for example, the UE prepares according to the value {1} in the timing relation set, and prepares to perform data buffering in the next time unit, the UE does not buffer data in the same time unit as the PDCCH before receiving the PDCCH, and when the UE finds that the value indicated by the timing relation indication information in the actual PDCCH is {0} after receiving the PDCCH, then starts data buffering, but a part of data may have been missed, and the UE cannot timely receive data, as shown in fig. 8. When the UE does not prepare according to the minimum value {0} in the timing relation set, for example, the UE prepares according to the value {1} in the timing relation set, and prepares to perform data buffering in the next time unit, the UE does not buffer data in the same time unit as the PDCCH before receiving the PDCCH, and after the UE receives the PDCCH, it finds that the value indicated by the timing relation indication information in the actual PDCCH is {1}, and then starts data buffering in the next time unit of the PDCCH, and the UE can timely receive data, as shown in fig. 9. Therefore, if the UE is not prepared according to the minimum value in the set of timing relationships, the UE may be able to receive data in time, or may not be able to receive data in time.

When the timing relation set from PDCCH to PDSCH is dynamically transformed, the minimum value in the timing relation set from PDCCH to PDSCH after transformation is larger than or equal to the minimum value in the timing relation set from PDCCH to PDSCH before transformation, and the UE is prepared according to the minimum value in the timing relation set from PDCCH to PDSCH before transformation, and the minimum value in the timing relation set from PDCCH to PDSCH before transformation is smaller than or equal to the minimum value in the timing relation set from PDCCH to PDSCH after transformation, so that the UE can timely receive data. For example, the higher layer signaling configures a set of 2 PDCCH-to-PDSCH timing relationships, set one being: {0,1,2,3}, set two is: {2,3,4,5}, when the set of timing relationships changes from set one to set two, the UE prepares according to the minimum value 0 in set one, all values in set two are greater than 0, so the UE can receive data in time.

When the minimum value in the set of the timing relationship of the PDCCH to the PDSCH after the transformation is smaller than the minimum value in the set of the timing relationship of the PDCCH to the PDSCH before the transformation, the UE is prepared according to the minimum value in the set of the timing relationship of the PDCCH to the PDSCH before the transformation, and the minimum value in the set of the timing relationship of the PDCCH to the PDSCH before the transformation is larger than the minimum value in the set of the timing relationship of the PDCCH to the PDSCH after the transformation, so the UE may not receive the data. For example, the higher layer signaling configures a set of 2 PDCCH-to-PDSCH timing relationships, set one being: {0,1,2,3}, set two is: {2,3,4,5}, when the timing relation set is changed from set two to set one, if the UE prepares according to the timing relation set from PDCCH to PDSCH before the change, the minimum value 2 in set two, and when the value indicated by the timing relation indication information in the actual PDCCH is 0 or 1, the UE does not buffer data, and the UE cannot receive data in time.

For the problems in the PDCCH-PDSCH timing relation set transformation described above, the following several methods can be adopted for processing.

The method comprises the following steps:

If the received PDCCH-PDSCH timing relationship set indicates that the PDCCH-PDSCH timing relationship set is different from the current PDCCH-PDSCH timing relationship set, that is, the PDCCH-PDSCH timing relationship set is to be transformed, then, within a period of time T from when the UE receives the PDCCH indicating the end start of the PDCCH-PDSCH timing relationship set transformation (for example, a period of time from when the UE receives the PDCCH indicating the end of the PDCCH-PDSCH timing relationship set transformation to when the next PDCCH monitoring opportunity starts, or a processing delay of the PDCCH), the UE still determines the PDCCH-PDSCH timing relationship according to the PDCCH-PDSCH timing relationship set before the transformation and the timing relationship indicating information in the PDCCH, and after the period of time T, the UE determines the PDCCH-PDSCH timing relationship according to the PDCCH-PDSCH timing relationship set after the transformation and the timing relationship indicating information in the PDCCH, as shown in fig. 10. For example, the higher layer signaling configures a set of 2 PDCCH-to-PDSCH timing relationships, set one being: {0,1,2,3}, set two is: {2,3,4,5}, before time slot n, the set of timing relationships is set one, and in time slot n, the set of timing relationships in the PDCCH indicates set two, at this time, the set of timing relationships has been transformed into set two, but the timing relationships in the PDCCH for scheduling PDSCH in time slot n are still determined according to set one of timing relationships, for example, when the timing relationship indication information value in the PDCCH for scheduling PDSCH is 01, the timing relationship is 1 according to the mapping relationship between the timing relationship indication information value and the timing relationship in table 1, that is, the UE is to receive PDSCH in time slot n+1. By adopting the method, the UE still uses the timing relation set before transformation in a certain time after receiving the instruction of transforming the timing relation set, so that the UE can receive data in time by preparing data receiving according to the minimum value in the timing relation set before transformation.

However, with this method, if the UE appears a PDCCH whose missed detection indicates that the timing relationship set is transformed, the UE and the base station may have different understandings about using the timing relationship set, for example, the higher layer signaling configures 2 sets of timing relationship from PDCCH to PDSCH, set one is: {0,1,2,3}, set two is: {2,3,4,5}, before slot n, the timing relation set is set one, in slot n, the timing relation set in PDCCH indicates timing relation set two, the base station considers that in slot n, the timing relation set is transformed into timing relation set two, in slot n, the UE does not receive PDCCH indicating that the timing relation set is transformed into set two, the UE considers that in slot n, the timing relation set is still set one, in slots n to n+T, the UE does not receive PDCCH, in slot n+T+1, the UE receives the timing relation set indicating timing relation set two in PDCCH, the UE considers that the UE receives an indication indicating that the timing relation set is transformed for the first time, and in slot n+T+1, the UE determines the timing relation from PDCCH to PDSCH according to the timing relation set before transformation; the base station considers that the UE receives the timing relation set in the PDCCH to indicate the timing relation set two in the time slot n, and the UE should determine the timing relation from the PDCCH to the PDSCH according to the transformed timing relation set (the timing relation set two) in the time slot n+t+1, so that the UE and the base station have different understandings about the time slot for receiving the PDSCH, as shown in fig. 11.

The second method is as follows:

If the timing relation set indication from PDCCH to PDSCH received by UE is different from the current timing relation set from PDCCH to PDSCH, that is, the timing relation set from PDCCH to PDSCH is to be transformed, at this time, the UE determines the timing relation from PDCCH to PDSCH according to the transformed timing relation set from PDCCH to PDSCH and the timing relation indication information in PDCCH, the UE prepares to receive data according to the minimum value in the timing relation set before transformation, in order to ensure that the UE prepares according to the minimum value in the timing relation set before transformation, the UE can timely receive data, within a period of time T from the UE receiving the end of PDCCH which indicates PDCCH to PDSCH transformation from the UE (for example, the period of time from the end of PDCCH which indicates PDCCH to PDSCH transformation to the next PDCCH monitoring opportunity starts from the end of PDCCH which indicates PDCCH to PDSCH transformation), the UE considers that the timing relation indication information indicated by the timing relation information in the PDCCH sent by the base station is not less than the minimum value in the timing relation set before transformation, and the UE does not wish to receive the timing relation information indicated by the timing relation information in the PDCCH sent by the base station to be less than the minimum value in the timing relation set before transformation, and the UE can timely receive data; after the period T, the UE considers that the timing relationship value indicated by the timing relationship indication information in the PDCCH of the scheduled PDSCH transmitted by the base station is smaller than the minimum value in the set of timing relationships before the transition, and the timing relationship value indicated by the timing relationship indication information in the PDCCH of the scheduled PDSCH transmitted by the base station may be not smaller than the minimum value in the set of timing relationships after the transition, as shown in fig. 12. After the UE receives the instruction of transforming the timing relation set, the UE uses the transformed timing relation set, and the UE can receive data in time by the implementation method of the base station in a certain time when the timing relation value indicated by the timing relation instruction information in the PDCCH of the scheduling PDSCH sent by the base station is not smaller than the minimum value in the timing relation set before transformation.

With this method, if the UE receives a period T from the UE to the end of the PDCCH indicating the PDCCH to PDSCH timing relation set transition (for example, a period from the end of the UE to the PDCCH indicating the PDCCH to PDSCH timing relation set transition to the start of the next PDCCH listening opportunity) when the UE has missed the PDCCH indicating the timing relation set transition, it may happen that the timing relation value indicated by the timing relation indication information in the PDCCH of the scheduled PDSCH transmitted by the base station is smaller than the minimum value in the timing relation set before transition, which is considered as an error case, and the UE discards the reception of the PDSCH. For example, the higher layer signaling configures a set of 2 PDCCH-to-PDSCH timing relationships, set one being: {0,1,2,3}, set two is: {2,3,4,5}, before slot n, the set of timing relationships is set two, in slot n, the set of timing relationships in PDCCH indicates the set of timing relationships one, in slot n, the base station considers that the set of timing relationships is transformed into the set of timing relationships one, in slot n, the UE does not receive PDCCH indicating the set of timing relationships is transformed into the set of sets one, the UE considers that the set of timing relationships is still the set of timing relationships two in slot n, in slots n to n+T, the UE does not receive PDCCH, in slot n+T+1, the UE receives the set of timing relationships indicating the set of timing relationships one in PDCCH, the UE considers that the UE receives an indication indicating the set of timing relationships transformed for the first time, in slot n+T+1, the UE determines the timing relationships from PDCCH to PDSCH according to the set of timing relationships one, but the UE considers that the value of the timing relationships indicated by the timing relationship indication information in PDCCH sent by the base station is not smaller than the minimum value {2} in the set of timing relationships before transformation; the base station considers that the UE has received one of the timing relationship sets in the PDCCH at the time slot n, and the timing relationship value indicated by the timing relationship indication information in the PDCCH of the scheduled PDSCH transmitted by the base station at the time slot n+t+1 is {0} and is smaller than the minimum value {2} in the timing relationship set before the transition, so that the timing relationship value indicated by the timing relationship indication information in the PDCCH of the scheduled PDSCH transmitted by the base station is {0}, and the UE considers this to be an error and cancels the PDSCH scheduled by the PDCCH of the time slot n+t+1 at the time slot n+t+1, as shown in fig. 13.

The above is a method of dynamically transforming the set of timing relationships (k 0) between the PDCCH for scheduling the PDSCH to the PDSCH being scheduled, and the following is a method of dynamically transforming the set of timing relationships (k 2) between the PDCCH for scheduling the PUSCH to the PUSCH being scheduled and a method of dynamically transforming the set of timing relationships (k 1) between the PDSCH to the HARQ-ACK transmission generated by the PDSCH.

Separate methods may be employed to indicate the 3 sets of timing relationships described above as dynamic transitions, respectively, or at least two of the 3 sets of timing relationships described above may be jointly indicated, e.g., a set of timing relationships (k 0) between the PDCCH scheduling PDSCH to the scheduled PDSCH and a set of timing relationships (k 1) between the PDSCH-to-PDSCH generated HARQ-ACK transmissions, as shown in table 4.

Table 4: timing relation (k 1) mapping table between indication field value and timing relation k0 of downlink allocation to downlink data and HARQ-ACK transmission generated from PDSCH to PDSCH

Indication field value	k0	k1
			00	0	2
01	1	3
			10	2	4
11	3	5

When the dynamic transition of the set of timing relation (k 0) between the PDCCH of the scheduled PDSCH to the PDSCH being scheduled is indicated by information in the PDCCH of the non-scheduled PDSCH (i.e. dedicated PDCCH), the UE may miss this indication information, where the base station considers that the timing relation (denoted as k 0-1) between the PDCCH of the scheduled PDSCH to the PDSCH being scheduled is used after the transition, the UE considers that the timing relation (denoted as k 0-0) between the PDCCH of the scheduled PDSCH to be used before the transition is used, where the set of timing relations S may be used, for example, where the number of bits of the timing relation indication information in the PDCCH of the scheduled PDSCH is unchanged regardless of the change of the set of timing relations (in addition, when the dynamic transition of the set of timing relation (k 0) between the PDCCH of the scheduled PDSCH to the PDCCH is indicated by information in the PDCCH of the scheduled PDSCH, in order to keep the number of bits of the PDCCH format unchanged, the timing relation indication information in the PDCCH may indicate the set of timing relation S before the constraint, e.g. S may include {0,1,2,3,4, 7, 8, 3, 8, and { 3, 6, 8, and {2,3, 5, 8, 3, 8 may be different sets may be included, and the set may be different, e.g. the set may include the set of the sets may be obtained.

Table 5: timing relation indicating value and timing relation k0 mapping table for downlink distribution to downlink data

Timing relation indication value	k0
		000	0
001	1
		010	2
011	3
		100	4
101	5
		110	6
111	7

By adopting the method, if the UE fails to detect the PDCCH of which the indication timing relation set is transformed, the corresponding relation between the indication value of the timing relation and the timing relation k0 which is distributed to the downlink data by the base station and the UE cannot be understood to be inconsistent.

When the UE fails to detect the indication information indicating the transition of the timing relation set, if the UE receives the timing relation indication value (denoted k0_1) smaller than the minimum value in the current timing relation set in the PDCCH of the scheduled PDSCH, the minimum value in the timing relation set becomes k0_1, the UE prepares to receive data according to the minimum value in the timing relation set being k0_1, for example, the current timing relation set is {2,3,4,5,6}, the timing relation minimum value is 2, the UE receives the timing relation value {0} in the PDCCH of the scheduled PDSCH, the timing relation minimum value becomes 0, and the UE prepares to receive data according to the minimum value in the timing relation set being 0.

When the UE configures more than one downlink BandWidth Part (BWP), the time interval indicated by the minimum value in the set of one BWP configured timing relation k0 is not greater than the time interval indicated by the maximum value in the set of any one BWP configured timing relation k0, which can ensure that the UE prepares to receive data according to the minimum value in the set of the timing relation k0 before BWP handover at the BWP handover, and when the PDCCH of the scheduled PDSCH indicating BWP handover is received, enables the UE to receive the scheduled PDSCH at the BWP after handover, otherwise, it is possible that the UE does not receive the PDSCH scheduled on the BWP after handover, for example, the set of timing relationships k0 of the pre-handover BWP is {4,5,6,7 }, the set of timing relationships k0 of the post-handover BWP is {0,1,2,3}, the minimum value 4 of the set of timing relationships k0 of the pre-handover BWP is greater than the maximum value 3 of the set of timing relationships k0 of the post-handover BWP, if the UE schedules PDSCH of the post-handover BWP on PDCCH of the pre-handover BWP, the time interval between the PDCCH and PDSCH it schedules is 3 slots, and the UE is ready to receive PDSCH according to the minimum value 4 of the set of timing relationships k0, and thus may not receive PDSCH spaced 3 slots from the PDCCH.

If the set dynamic transition of the timing relationship (k 0) between the PDCCH of the scheduled PDSCH to the PDSCH to be scheduled is indicated by information in the PDCCH of the non-scheduled PDSCH (i.e., dedicated PDCCH), if the UE receives the dedicated PDCCH, the UE is to feed back ACK information, the dedicated PDCCH may include an HARQ timing relationship indication indicating a dedicated PDCCH to ACK transmission time interval, or the dedicated PDCCH to ACK transmission time interval is determined by a higher layer signaling configuration.

The dedicated PDCCH may be transmitted in a configured period, and the UE prepares to receive the PDSCH in accordance with the minimum value of the indicated set of timing relationships if the UE receives the dedicated PDCCH at the configured period, in accordance with the minimum value of the default set of timing relationships if the UE does not receive the dedicated PDCCH at the configured period, or in accordance with the minimum value of the set of timing relationships indicated by the last recently received dedicated PDCCH.

When the scheme of dynamically changing the set of timing relationships (k 0) between the PDCCHs of the scheduled PDSCH to the set of timing relationships (k 2) between the PDCCHs of the scheduled PUSCH and the scheduled PUSCH is applied to the dynamic change of the set of timing relationships (k 2) between the PDCCHs of the scheduled PDSCH to the set of scheduled PUSCH, for example, the PDCCH of the scheduled PDSCH is replaced with the PDCCH of the scheduled PUSCH, the PDSCH is replaced with the PUSCH, the timing relationship (k 0) between the PDCCH of the scheduled PDSCH to the PDSCH is replaced with the timing relationship (k 2) between the PDCCH of the scheduled PUSCH, and the set of timing relationships (k 0) between the PDCCH of the scheduled PDSCH to the PUSCH is replaced with the set of timing relationships (k 2) between the PDCCH of the scheduled PUSCH and the PUSCH.

When the scheme of dynamically transforming the set of timing relationships (k 0) between the PDCCH for scheduling the PDSCH and the scheduled PDSCH is applied to dynamically transforming the set of timing relationships (k 1) between the PDCCH for scheduling the PDSCH and the HARQ-ACK transmission generated by the PDSCH, for example, the PDCCH for scheduling the PDSCH is replaced by the PDSCH for generating the HARQ-ACK, the scheduled PDSCH is replaced by the HARQ-ACK generated by the PDSCH, the timing relationships (k 0) between the PDCCH for scheduling the PDSCH and the scheduled PDSCH are replaced by the set of timing relationships (k 1) between the PDCCH for scheduling the PDSCH and the HARQ-ACK transmission generated by the PDSCH, and the set of timing relationships (k 0) between the PDCCH for scheduling the PDSCH and the scheduled PDSCH is replaced by the set of timing relationships (k 1) between the PDCCH and the HARQ-ACK transmission generated by the PDSCH.

In the application, the timing relation set is dynamically transformed, the electricity consumption of the UE is saved, and the timely transmission of data is ensured.

The communication module 1490 may include one or more communication processors capable of operating independently of the processor 1420 (e.g., an Application Processor (AP)) and support direct (e.g., wired) or wireless communication. According to an embodiment, the communication module 1490 may include a wireless communication module 1492 (e.g., a cellular communication module, a short-range wireless communication module, or a Global Navigation Satellite System (GNSS) communication module) or a wired communication module 1494 (e.g., a Local Area Network (LAN) communication module or a Power Line Communication (PLC) module).

In this case, at least one antenna suitable for a communication scheme used in a communication network, such as the first network 1498 or the second network 1499, may be selected from the plurality of antennas by, for example, the communication module 1490 (e.g., the wireless communication module 1492). Signals or power may then be transmitted or received between the communication module 1490 and the external electronic device via the selected at least one antenna. According to embodiments, further components (e.g., a Radio Frequency Integrated Circuit (RFIC)) other than radiating elements may additionally be formed as part of the antenna module 1497.

At least some of the above components may be interconnected via an inter-peripheral communication scheme (e.g., bus, general Purpose Input Output (GPIO), serial Peripheral Interface (SPI), or Mobile Industrial Processor Interface (MIPI)) and communicatively communicate signals (e.g., commands or data) therebetween.

According to an embodiment, commands or data may be sent or received between the electronic device 1401 and the external electronic device 1404 via the server 1408 connected to the second network 1499. Each of the electronic device 1402 and the electronic device 1404 may be the same type of device as the electronic device 1401, or a different type of device from the electronic device 1401. According to an embodiment, all or some of the operations to be performed at the electronic device 1401 may be performed at one or more of the external electronic device 1402, the external electronic device 1404, or the server 1408. For example, if the electronic device 1401 should automatically perform a function or service or should perform a function or service in response to a request from a user or another device, the electronic device 1401 may request the one or more external electronic devices to perform at least part of the function or service instead of or in addition to the function or service, or the electronic device 1401 may request the one or more external electronic devices to perform at least part of the function or service. The one or more external electronic devices that receive the request may perform the requested at least part of the functions or services, or perform additional functions or additional services related to the request, and transmit the result of the performance to the electronic device 1401.
