Description

User equipment, electronic equipment, wireless communication method, and storage medium

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on February 16, 2023, with application number 202310125606.7 and invention name “User Equipment, Electronic Device, Wireless Communication Method and Storage Medium”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] Embodiments of the present disclosure generally relate to the field of wireless communications, and more particularly, to user equipment, electronic devices, wireless communication methods, and computer-readable storage media. More particularly, the present disclosure relates to a user equipment in a wireless communication system, an electronic device serving as a base station device in the wireless communication system, a wireless communication method performed by the user equipment in the wireless communication system, a wireless communication method performed by the base station device in the wireless communication system, and a computer-readable storage medium. Background Art

[0003] To enhance the throughput of sidelink (SL) UEs (User Equipment) and support higher-speed services, the FR2 frequency band was introduced. When SL UEs operate in the FR2 frequency band, they communicate with each other using beamforming.

[0004] Before user equipment A and user equipment B can communicate over a direct link, they must first synchronize time and frequency and obtain broadcast information. After user equipment A is powered on, it searches for a synchronization source based on the base station configuration or pre-configured synchronization priority rules. Once user equipment A finds the highest-priority synchronization source and establishes synchronization with it, it sends an S-SSB (Sidelink-Synchronization Signal Block) message to synchronize other user equipment around it with user equipment A.

[0005] If user device A operates in the FR2 frequency band, it can only send S-SSB in the direction of the current beam. Only other user devices within the coverage area of ​​the beam can receive the synchronization information and establish synchronization with user device A. This synchronization information transmission mechanism greatly reduces the possibility of synchronization between user device A and other nearby user devices, thereby reducing data transmission rates and degrading service quality.

[0006] Therefore, it is necessary to propose a technical solution to optimize the synchronization process between SL UEs operating in the FR2 frequency band.

[0044] <1. Description of the problem>

[0045] As mentioned earlier, SL UEs operating in the FR2 band can only use beamforming to transmit S-SSB. This synchronization mechanism significantly reduces the likelihood of synchronization between UEs, lowering data rates and reducing service quality.

[0046] Aiming at such a scenario, the present disclosure proposes a user equipment, an electronic device, a wireless communication method, and a computer-readable storage medium in a wireless communication system to optimize the synchronization process between SL UEs operating in the FR2 frequency band.

In addition, the user equipment may be a wireless communication module (such as an integrated circuit module including a single chip) installed on each of the above-mentioned terminals.

[0050] The wireless communication system according to the present disclosure can be applied to a vehicle network system, and the user equipment may include a vehicle, or the user equipment may be placed or integrated into a vehicle. In this scenario, the wireless communication system may also include one or more RSUs (Road Side Units).

[0051] <2. User Equipment Configuration Example>

[0052] FIG. 1 is a block diagram illustrating an example of a configuration of a user equipment 100 according to an embodiment of the present disclosure.

[0053] As shown in FIG. 1 , the user equipment 100 may include a configuration unit 110 and a communication unit 120 .

[0054] Here, each unit of user equipment 100 may be included in a processing circuit. It should be noted that user equipment 100 may include either one processing circuit or multiple processing circuits. Furthermore, the processing circuit may include various discrete functional units to perform various functions and / or operations. It should be noted that these functional units may be physical or logical entities, and units with different names may be implemented by the same physical entity.

[0055] According to an embodiment of the present disclosure, the configuration unit 110 may determine the configuration of the synchronization signal block of the user equipment 100 according to the configuration of the synchronization beam of the user equipment 100. Here, the configuration of the synchronization signal block may include the activated synchronization beam of the user equipment 100. That is, the configuration of the synchronization signal block may include information about which synchronization beams the user equipment 100 uses to transmit the synchronization signal block.

[0056] According to an embodiment of the present disclosure, the user equipment 100 may transmit a synchronization signal block using the activated synchronization beam by using the communication unit 120 according to the configuration of the configuration unit 110 so that other user equipments are synchronized with the user equipment 100 .

[0057] Thus, according to the embodiment of the present disclosure, the user equipment 100 can determine the configuration of the synchronization signal block of the user equipment 100, which includes the activated synchronization beam. In other words, the user equipment 100 can determine which synchronization beams to use to transmit the synchronization signal block. In this way, the synchronization beam used to transmit the synchronization signal block can be reasonably determined, thereby increasing the possibility of synchronization between user equipments and optimizing the synchronization process between SL UEs operating in the FR2 frequency band.

[0058] According to an embodiment of the present disclosure, a synchronization signal block may be an S-SSB, which is a synchronization signal block for SL and includes information for SL synchronization. One S-SSB occupies one time slot in the time domain and 11 RBs (Resource Blocks) in the frequency domain.

[0059] According to an embodiment of the present disclosure, a synchronization beam may be a beam used to transmit a synchronization signal block. The configuration of a synchronization beam may include configuration information such as the number of synchronization beams and the direction of each synchronization beam. This configuration information may be set by the base station device of the user equipment 100 or may be set when the user equipment 100 leaves the factory.

[0060] According to an embodiment of the present disclosure, the configuration unit 110 may determine an activated synchronization beam according to the number of synchronization beams of the user equipment 100 and the directions of the synchronization beams.

[0061] According to an embodiment of the present disclosure, when the number of synchronization beams of the user equipment 100 is greater than a first threshold, the configuration unit 110 may determine to activate a portion of all synchronization beams of the user equipment 100. Here, the configuration unit 110 may determine that a predetermined proportion of all synchronization beams are activated. In addition, the configuration unit 110 may randomly select a portion of the synchronization beams to activate, or may uniformly configure the synchronization beams activated in various directions. For example, when the configuration unit 110 determines that half of all synchronization beams are activated, every other synchronization beam may be activated.

[0062] According to an embodiment of the present disclosure, the configuration unit 110 can activate a portion of the synchronization beams of the user equipment 100. This increases the likelihood of synchronization for other user equipment in the direction of the activated synchronization beams. For example, if the user equipment 100 has eight synchronization beams and four synchronization beams are activated, and another user equipment fails to synchronize successfully upon first receiving a synchronization signal block, the other user equipment only needs to wait for the coverage time of the four synchronization beams to obtain the next opportunity to receive a synchronization signal block.

[0063] According to an embodiment of the present disclosure, when the number of synchronization beams of the user equipment 100 is less than or equal to the first threshold, the configuration unit 110 may determine to activate all synchronization beams, so that other user equipments in all directions have equal synchronization opportunities.

[0064] According to an embodiment of the present disclosure, the user equipment 100 may determine the first threshold value according to the capability of the user equipment 100. For example, the capability of the user equipment 100 may be determined according to parameters such as the processing speed of the CPU of the user equipment 100, antenna settings, and power information.

[0065] Figures 2 and 3 are schematic diagrams illustrating activated synchronization beams for a user equipment according to an embodiment of the present disclosure. In Figures 2 and 3, the user equipment is represented by a vehicle. Here, it is assumed that the first threshold is 4. Figures 2 and 3 illustrate an example in which the user equipment determines an activated synchronization beam based solely on the configuration of the synchronization beam.

[0066] As shown in Figure 2, the user equipment has eight synchronization beams numbered 0-7, which are greater than the first threshold. Therefore, configuration unit 110 may determine to activate some of the synchronization beams. The activated synchronization beams are indicated by solid lines in Figure 2. As shown in Figure 2, the user equipment has activated synchronization beams 0, 2, 3, and 6.

[0067] As shown in Figure 3, the user equipment has four synchronization beams numbered 0-3, which are equal to the first threshold. Therefore, the configuration unit 110 can determine to activate all synchronization beams. The activated synchronization beams are shown in solid lines in Figure 3. As shown in Figure 3, the user equipment has activated all synchronization beams 0, 1, 2, and 3.

[0068] According to an embodiment of the present disclosure, the configuration of the synchronization signal block may further include the number of times the synchronization signal block is continuously sent using each activated synchronization beam.

[0069] According to an embodiment of the present disclosure, the user equipment 100 can send synchronization signal blocks multiple times within a 160ms synchronization signal transmission cycle. The total number of synchronization signal blocks can be configured by the base station device of the user equipment 100, or can be configured when the user equipment 100 leaves the factory. For example, when the subcarrier spacing of the user equipment 100 is 60kHz, the total number of synchronization signal blocks can be 1, 2, 4, 8, 16, or 32; when the subcarrier spacing of the user equipment 100 is 120kHz, the total number of synchronization signal blocks can be 1, 2, 4, 8, 16, 32, or 64. In addition, the time domain positions of these multiple synchronization signal blocks can be determined by the parameters s1-TimeOffsetSSB-r16 and s1-TimeInterval-r16. The parameter s1-TimeOffsetSSB-r16 represents the time interval between the first synchronization signal block and the start time of the synchronization signal transmission cycle, in time slots, and the parameter s1-TimeInterval-r16 represents the time interval between two adjacent synchronization signal blocks, in time slots. Similarly, the time domain positions of these multiple synchronization signal blocks can be configured by the base station device of the user equipment 100, or can be configured when the user equipment 100 leaves the factory.

[0070] According to an embodiment of the present disclosure, the user equipment 100 may transmit synchronization signal blocks by polling the activated synchronization beams. That is, the user equipment 100 may sequentially transmit one or more synchronization signal blocks from a plurality of synchronization signal blocks using each activated synchronization beam. The configuration unit 110 may determine the number of consecutive transmissions of synchronization signal blocks using each activated synchronization beam. In other words, the configuration unit 110 may determine the number of consecutive transmissions of synchronization signal blocks using each activated synchronization beam.

[0071] Figures 4 and 5 are schematic diagrams illustrating the number of times each activated synchronization beam is used to continuously transmit synchronization signal blocks according to an embodiment of the present disclosure. In Figures 4 and 5 , it is assumed that the total number of synchronization signal blocks of user equipment 100 is 8. Figure 4 illustrates a scenario where user equipment 100 has an activated synchronization beam as shown in Figure 2 , and Figure 5 illustrates a scenario where user equipment 100 has an activated synchronization beam as shown in Figure 3 .

[0072] As shown in FIG4 , in Example A, the configuration unit 110 may determine that the number of times the user equipment 100 continuously transmits synchronization signal blocks using each activated synchronization beam is equal to 1. Therefore, the user equipment 100 transmits the first S-SSB using the activated synchronization beam 0, the second S-SSB using the activated synchronization beam 2, the third S-SSB using the activated synchronization beam 3, the fourth S-SSB using the activated synchronization beam 6, and then transmits the fifth S-SSB using the activated synchronization beam 0, the sixth S-SSB using the activated synchronization beam 2, the seventh S-SSB using the activated synchronization beam 3, and the eighth S-SSB using the activated synchronization beam 6. In Example B, the configuration unit 110 may determine that the number of times the user equipment 100 continuously transmits synchronization signal blocks using each activated synchronization beam is greater than 1 (shown as 2 in FIG4 ). Therefore, the user equipment 100 sends the first S-SSB and the second S-SSB using the activated synchronization beam 0, sends the third S-SSB and the fourth S-SSB using the activated synchronization beam 2, sends the fifth S-SSB and the sixth S-SSB using the activated synchronization beam 3, and sends the seventh S-SSB and the eighth S-SSB using the activated synchronization beam 6.

[0073] According to an embodiment of the present disclosure, when some synchronization beams are activated, the configuration unit 110 may determine that the number of times synchronization signal blocks are continuously transmitted using each activated synchronization beam is greater than 1. That is, example B shown in FIG4 may be preferably adopted.

[0074] According to an embodiment of the present disclosure, since each activated synchronization beam continuously transmits synchronization signal blocks more than 1 times, the dwell time of each activated synchronization beam is extended. This increases the likelihood that user equipment within the coverage of the synchronization beam will synchronize with user equipment 100.

[0075] As shown in FIG5 , in Example C, the configuration unit 110 may determine that the number of times the user equipment 100 continuously transmits synchronization signal blocks using each activated synchronization beam is equal to 1. Therefore, the user equipment 100 transmits the first S-SSB using the activated synchronization beam 0, the second S-SSB using the activated synchronization beam 1, the third S-SSB using the activated synchronization beam 2, the fourth S-SSB using the activated synchronization beam 3, and then transmits the fifth S-SSB using the activated synchronization beam 0, the sixth S-SSB using the activated synchronization beam 1, the seventh S-SSB using the activated synchronization beam 2, and the eighth S-SSB using the activated synchronization beam 3. In Example D, the configuration unit 110 may determine that the number of times the user equipment 100 continuously transmits synchronization signal blocks using each activated synchronization beam is greater than 1 (shown as 2 in FIG5 ). Therefore, the user equipment 100 sends the first S-SSB and the second S-SSB using the activated synchronization beam 0, sends the third S-SSB and the fourth S-SSB using the activated synchronization beam 1, sends the fifth S-SSB and the sixth S-SSB using the activated synchronization beam 2, and sends the seventh S-SSB and the eighth S-SSB using the activated synchronization beam 3.

[0076] According to an embodiment of the present disclosure, when all synchronization beams are activated, the configuration unit 110 may determine that the number of times synchronization signal blocks are continuously transmitted using each activated synchronization beam is equal to 1. That is, example C shown in FIG5 may be preferably adopted.

[0077] According to an embodiment of the present disclosure, since the number of times synchronization signal blocks are continuously sent using each activated synchronization beam is equal to 1, the synchronization signal blocks can be sent in each direction as quickly as possible, so that other user devices in each direction obtain equal synchronization opportunities.

[0078] According to an embodiment of the present disclosure, when the number of times the synchronization signal block is continuously transmitted using the activated synchronization beam is greater than 1, the configuration unit 110 can set the number of times the synchronization signal block is continuously transmitted as needed. For example, the configuration unit 110 can set the number to a fixed value, such as 2 or 3.

[0079] According to an embodiment of the present disclosure, the configuration unit 110 may also determine the number of times synchronization signal blocks are continuously transmitted using each activated synchronization beam based on the number of activated synchronization beams and the total number of times synchronization signal blocks are to be transmitted. Specifically, the configuration unit 110 may determine the value obtained by dividing the total number of times synchronization signal blocks are to be transmitted by the number of activated synchronization beams as the number of times synchronization signal blocks are continuously transmitted using each activated synchronization beam.

[0080] FIG6 is a schematic diagram illustrating the number of times each activated synchronization beam is used to continuously transmit synchronization signal blocks according to an embodiment of the present disclosure. In FIG6 , it is assumed that the total number of synchronization signal blocks of the user equipment 100 is 16, and FIG6 illustrates a situation in which the user equipment 100 has the activated synchronization beams as shown in FIG2 . Here, the configuration unit determines that the user equipment 100 has 4 activated synchronization beams, and therefore can determine that the number of times synchronization signal blocks are continuously transmitted using each activated synchronization beam is 4. As shown in FIG6 , in Example E, the user equipment 100 transmits the 1st to 4th S-SSBs using the activated synchronization beam 0, transmits the 5th to 8th S-SSBs using the activated synchronization beam 2, transmits the 9th to 12th S-SSBs using the activated synchronization beam 3, and transmits the 13th to 16th S-SSBs using the activated synchronization beam 6.

[0081] As described above, according to an embodiment of the present disclosure, the configuration unit 110 can determine the activated synchronization beams of the user equipment 100 based on the configuration of the synchronization beams of the user equipment 100. Optionally, the configuration unit 110 can also determine the number of times the user equipment 100 continuously transmits synchronization signal blocks using each activated synchronization beam based on the configuration of the synchronization beams of the user equipment 100. Here, the synchronization beam configuration may include the direction of each synchronization beam configured for the user equipment 100 and the total number of configured synchronization beams. Specifically, if the user equipment 100 is configured with a large number of synchronization beams, some synchronization beams can be activated to conserve resources. If the user equipment 100 is configured with a small number of synchronization beams, all synchronization beams can be activated to ensure that other user equipment in all directions have equal opportunities to synchronize. Furthermore, if the user equipment 100 is configured with a large number of synchronization beams, synchronization signal blocks can be continuously transmitted multiple times using the activated synchronization beams to increase the likelihood that other user equipment will synchronize with the user equipment 100. In the case where the user equipment 100 is configured with fewer synchronization beams, the synchronization signal block can be continuously sent once using the activated synchronization beam to enable other user equipments in all directions to synchronize with the user equipment 100 as quickly as possible.

[0082] According to an embodiment of the present disclosure, the configuration unit 110 may further determine the configuration of the synchronization signal block of the user equipment 100 based on the distribution of other user equipments around the user equipment 100. Here, the other user equipments around the user equipment 100 include all other user equipments capable of SL communication within a predetermined range of the user equipment 100. The predetermined range here may be, for example, a range within which a signal transmitted by the user equipment 100 can be received, i.e., such a predetermined range may be set based on the strength of the signal transmitted by the user equipment 100.

[0083] According to an embodiment of the present disclosure, the user equipment 100 may receive the distribution information of other user equipment around the user equipment 100 from other devices through the communication unit 120. The other devices here may include the base station device of the user equipment 100. In the case where the user equipment 100 is located in the Internet of Vehicles, the other devices may also include devices around the user equipment 100 such as RSU, roadside perception equipment, roadside camera equipment, etc. that can collect information about other user equipment around the user equipment 100. Here, the user equipment 100 may receive such distribution information through MAC (Media Access Control) or RRC (Radio Resource Control) signaling.

[0084] According to an embodiment of the present disclosure, the user device 100 may periodically receive such distribution information from other devices. Alternatively, the user device 100 may send a request message requesting the distribution information to other devices, thereby receiving the distribution information sent by the other devices in response to the request message.

[0085] According to an embodiment of the present disclosure, as shown in FIG1 , the user equipment 100 may further include a sensing unit 130 for sensing the distribution of other user equipment around the user equipment 100. The sensing unit 130 may include a sensing device such as a radar or a camera provided in the user equipment 100.

[0086] According to an embodiment of the present disclosure, the distribution of other user devices around the user device 100 may include the number of other user devices in various directions around the user device. Here, each direction may correspond to the direction of each synchronization beam of the user device 100. In other words, the distribution of other user devices around the user device 100 may include the number of other user devices in directions corresponding to the directions of each synchronization beam of the user device 100 within a predetermined range of the user device 100.

[0087] For example, when the user equipment 100 receives distribution information from other devices, the other devices may send the locations of all other surrounding user devices to the user equipment 100, so that the user equipment 100 can determine the number of other user devices in the direction corresponding to each synchronization beam. Alternatively, when the other devices are aware of the directions of each synchronization beam of the user equipment 100, the other devices may determine the number of other user devices in the direction corresponding to each synchronization beam of the user equipment 100, and thus send the number information in each direction to the user equipment 100. When the sensing unit 130 senses the distribution information, the sensing unit 130 may sense the locations of other user devices around the user equipment 100, and thus determine the number of other user devices in the direction corresponding to each synchronization beam.

[0088] According to an embodiment of the present disclosure, the configuration unit 110 may determine the activated synchronization beam of the user equipment 100 based on the distribution of other user equipment around the user equipment 100 and the configuration of the synchronization beam of the user equipment. Here, the configuration of the synchronization beam of the user equipment 100 may include the direction of each synchronization beam configured for the user equipment 100. Specifically, the configuration unit 110 may determine the activated synchronization beam based on the relationship between the number of other user equipment in the direction corresponding to the direction of each synchronization beam and the second threshold. Specifically, the configuration unit 110 may determine to activate the synchronization beam in the direction in which the number of other user equipment is greater than the second threshold, and not to activate the synchronization beam in the direction in which the number of other user equipment is less than or equal to the second threshold.

[0089] According to an embodiment of the present disclosure, the second threshold is used to determine the threshold for activated synchronization beams. User equipment 110 can set the value of the second threshold based on actual conditions. For example, user equipment 110 can set the second threshold to a non-negative integer, or determine the second threshold based on the number of other user equipment in each direction, so that the ratio of activated synchronization beams to all synchronization beams is a fixed value. Preferably, the second threshold can be 0. In other words, as long as there are other user equipment in the direction corresponding to the direction of the synchronization beam, the synchronization beam is activated.

[0090] Figures 7 and 8 are schematic diagrams illustrating the activated synchronization beams of a user device according to an embodiment of the present disclosure. In the examples shown in Figures 7 and 8, the second threshold is 0. As shown in Figure 7, the user device is configured with eight synchronization beams numbered 0-7. There are three other user devices in the direction of synchronization beam 0, two other user devices in the direction of synchronization beam 1, two other user devices in the direction of synchronization beam 4, one other user device in the direction of synchronization beam 6, and no other user devices in the directions of synchronization beams 2, 3, 5, and 7. Therefore, according to an embodiment of the present disclosure, the configuration unit 110 may determine to activate synchronization beams 0, 1, 4, and 6, and deactivate synchronization beams 2, 3, 5, and 7. As shown in Figure 8, the user device is configured with four synchronization beams numbered 0-3. There are five other user devices in the direction of synchronization beam 0, no other user devices in the direction of synchronization beam 1, two other user devices in the direction of synchronization beam 2, and one other user device in the direction of synchronization beam 3. Therefore, according to an embodiment of the present disclosure, the configuration unit 110 may determine to activate synchronization beams 0, 2, and 3, and not to activate synchronization beam 1.

[0091] According to an embodiment of the present disclosure, the configuration of the synchronization signal block may further include the number of times the synchronization signal block is continuously transmitted using each activated synchronization beam. In other words, the configuration unit 110 may further determine the number of times the synchronization signal block is continuously transmitted using each activated synchronization beam based on the configuration of the synchronization beam and the distribution of other user devices. The configuration of the synchronization beam here may include the direction of each synchronization beam configured for the user device 100.

[0092] According to an embodiment of the present disclosure, the configuration unit may determine the number of times synchronization signal blocks are continuously sent using the synchronization beam based on the relationship between the number of other user devices in the direction corresponding to the direction of each synchronization beam and a third threshold. Specifically, for an activated synchronization beam in a direction in which the number of other user devices is greater than the third threshold, it is determined that the number of times synchronization signal blocks are continuously sent using the activated synchronization beam is greater than 1, and for an activated synchronization beam in a direction in which the number of other user devices is less than or equal to the third threshold, it is determined that the number of times synchronization signal blocks are continuously sent using the activated synchronization beam is equal to 1.

[0093] Here, the third threshold is a threshold used to determine the number of times a synchronization signal block is continuously transmitted using a synchronization beam. Preferably, the third threshold is a non-negative integer and may be greater than or equal to the second threshold. When the third threshold is greater than the second threshold, the configuration unit 110 may select some synchronization beams from the activated synchronization beams to continuously transmit the synchronization signal block multiple times. When the third threshold is equal to the second threshold, the configuration unit 110 may determine to continuously transmit the synchronization signal block multiple times on all activated synchronization beams.

[0094] Figure 9 is a schematic diagram showing the number of times each activated synchronization beam is used to continuously transmit synchronization signal blocks according to an embodiment of the present disclosure. In Figure 9, the total number of S-SSBs is 8, and the configuration of the synchronization beam of the user equipment 100 and the distribution of other surrounding user equipment are shown in Figure 7. That is, synchronization beams 0, 1, 4, and 6 are activated for the user equipment 100. In example F, it is assumed that the third threshold is 2. That is, the number of other user equipment in the direction of synchronization beam 0 is greater than the third threshold, while the number of other user equipment in the directions of synchronization beams 1, 4, and 6 is less than or equal to the third threshold. Therefore, according to an embodiment of the present disclosure, the configuration unit 110 can determine that synchronization beam 0 continuously transmits synchronization signal blocks multiple times, and synchronization beams 1, 4, and 6 continuously transmit synchronization signal blocks once. As shown in Example F, the user equipment 100 transmits the first and second S-SSBs using synchronization beam 0, transmits the third S-SSB using synchronization beam 1, transmits the fourth S-SSB using synchronization beam 4, transmits the fifth S-SSB using synchronization beam 6, and then transmits the sixth and seventh S-SSBs using synchronization beam 0 again, and transmits the eighth S-SSB using synchronization beam 1. In Example G, it is assumed that the third threshold is 0. That is, the number of other user equipments in the directions of synchronization beams 0, 1, 4, and 6 is greater than the third threshold. Therefore, according to an embodiment of the present disclosure, the configuration unit 110 can determine that synchronization beams 0, 1, 4, and 6 transmit synchronization signal blocks multiple times in succession. As shown in Example G, the user equipment 100 sends the first S-SSB and the second S-SSB using synchronization beam 0, sends the third S-SSB and the fourth S-SSB using synchronization beam 1, sends the fifth S-SSB and the sixth S-SSB using synchronization beam 4, and sends the seventh S-SSB and the eighth S-SSB using synchronization beam 6.

[0095] According to an embodiment of the present disclosure, when the configuration of the synchronization beam of the user equipment 100 and the distribution of other surrounding user equipment are as shown in Figure 8, assuming that the third threshold is 2, the configuration unit 110 can determine that beam 0 sends the synchronization signal block continuously for multiple times, while beams 2 and 3 send the synchronization signal block continuously once; assuming that the third threshold is 0, the configuration unit can determine that beams 0, 2 and 3 all send the synchronization signal block continuously for multiple times.

[0096] According to an embodiment of the present disclosure, when the third threshold is equal to the second threshold, the configuration unit 110 may determine that the synchronization signal blocks are continuously sent multiple times on all activated synchronization beams. Here, the configuration unit 110 may determine the number of times the synchronization signal blocks are continuously sent using each activated synchronization beam based on the number of activated synchronization beams and the total number of times the synchronization signal blocks are to be sent. Specifically, the configuration unit 110 may determine the value obtained by dividing the total number of times the synchronization signal blocks are to be sent by the number of activated synchronization beams as the number of times the synchronization signal blocks are continuously sent using each activated synchronization beam. For example, in Example G of Figure 9, the total number of times the synchronization signal blocks are to be sent is 8, and the number of activated synchronization beams is 4, so it can be determined that the number of times the synchronization signal blocks are continuously sent using each activated synchronization beam is 2.

[0097] As described above, according to an embodiment of the present disclosure, the configuration unit 110 can determine the activated synchronization beam and the number of times synchronization signal blocks are continuously sent using each synchronization beam based on the configuration of the synchronization beam and the distribution of other user devices around the user device 100. The configuration of the synchronization beam here may include the direction of each synchronization beam of the user device 100. Specifically, the synchronization beam is activated in the direction where the number of other user devices is large, and the synchronization beam is not activated in the direction where the number of other user devices is small. In this way, the possibility of other user devices synchronizing with the user device 100 can be increased, while avoiding sending synchronization information in the direction where the number of other user devices is small or there are no other user devices, so as to save resources. Furthermore, multiple synchronization signal blocks can be continuously sent in the direction where the number of other user devices is large to further increase the possibility of other user devices in that direction synchronizing with the user device 100.

[0098] According to an embodiment of the present disclosure, the configuration unit 110 may further determine an activated synchronization beam based on the direction of each synchronization beam of the user equipment 100, the number of all synchronization beams, and the distribution of other user equipment around the user equipment 100. Specifically, when the number of synchronization beams of the user equipment 100 is greater than a first threshold, the synchronization beams in the direction where the number of other user equipment is greater than a second threshold are determined to be activated, and the synchronization beams in the direction where the number of other user equipment is less than or equal to the second threshold are not activated; when the number of synchronization beams of the user equipment 100 is less than or equal to the first threshold, all synchronization beams are determined to be activated.

[0099] Similarly, the configuration of the synchronization signal block may further include the number of times the synchronization signal block is continuously transmitted using each activated synchronization beam. For an activated synchronization beam in a direction where the number of other user equipment is greater than a third threshold, determining that the number of times the synchronization signal block is continuously transmitted using the activated synchronization beam is greater than 1, and for an activated synchronization beam in a direction where the number of other user equipment is less than or equal to the third threshold, determining that the number of times the synchronization signal block is continuously transmitted using the activated synchronization beam is equal to 1.

[0100] That is, only when the user equipment 100 is configured with a relatively large number of synchronization beams, the activated synchronization beam is determined based on the second threshold, and the number of consecutive transmissions of synchronization signal blocks using each activated synchronization beam can be further determined based on the third threshold. When the user equipment 100 is configured with a relatively small number of synchronization beams, all synchronization beams are activated. Furthermore, the number of consecutive transmissions of synchronization signal blocks using each activated synchronization beam can also be determined based on the third threshold.

[0101] For example, when the first threshold is 4, in the example shown in FIG7 , the number of synchronization beams of the user equipment 100, 8, is greater than the first threshold. The configuration unit 110 may determine to activate synchronization beams 0, 1, 4, and 6 based on the second threshold as described above, and then determine the number of times each activated synchronization beam continuously transmits a synchronization signal block based on the third threshold as described above. In the example shown in FIG8 , the number of synchronization beams of the user equipment 100, 4, is equal to the first threshold. The configuration unit 110 may determine to activate all synchronization beams 0, 1, 2, and 3, and then determine the number of times each activated synchronization beam continuously transmits a synchronization signal block based on the third threshold as described above.

[0102] According to an embodiment of the present disclosure, when the configuration unit 110 determines that synchronization signal blocks are to be continuously transmitted multiple times on all activated synchronization beams, the configuration unit 110 may determine the number of times synchronization signal blocks are to be continuously transmitted using each activated synchronization beam based on the number of activated synchronization beams and the total number of times synchronization signal blocks are to be transmitted. Specifically, the configuration unit 110 may determine the value obtained by dividing the total number of times synchronization signal blocks are to be transmitted by the number of activated synchronization beams as the number of times synchronization signal blocks are to be continuously transmitted using each activated synchronization beam.

[0103] As described above, according to the embodiments of the present disclosure, the configuration unit 110 can determine the activated synchronization beams and the number of synchronization signal blocks to be continuously transmitted using each synchronization beam based on the directions of the synchronization beams of the user equipment 100, the number of all synchronization beams, and the distribution of other user equipment around the user equipment 100. Specifically, if the user equipment 100 is configured with fewer synchronization beams, all synchronization beams can be activated, thereby ensuring that other user equipment in all directions around the user equipment have equal opportunities for synchronization. If the user equipment 100 is configured with more synchronization beams, some synchronization beams can be activated based on a second threshold, thereby saving resources.

[0104] As described above, the configuration unit 110 can determine the configuration of the synchronization signal block based on the direction and number of synchronization beams configured for the user equipment 100, or can determine the configuration of the synchronization signal block based on the direction and number of synchronization beams configured for the user equipment and the distribution of other user equipment around the user equipment 100, or can determine the configuration of the synchronization signal block based on the direction and number of synchronization beams configured for the user equipment 100 and the distribution of other user equipment around the user equipment 100. Of course, the configuration unit 110 can also determine the configuration of the synchronization signal block based on other parameters. For example, the configuration unit 110 can determine the configuration of the synchronization signal block based on the importance of information to be transmitted by other user equipment around the user equipment 100. Here, the synchronization beam can be activated in the direction of other user equipment that transmits highly important information, such as security information. Optionally, the synchronization beam can also be used to continuously transmit synchronization signal blocks multiple times to increase the possibility that other user equipment in that direction will synchronize with the user equipment 100.

[0105] In addition, according to an embodiment of the present disclosure, the configuration unit 110 may combine the above-mentioned embodiments for determining the configuration of the synchronization signal block. For example, the configuration unit 110 may preferentially determine the configuration of the synchronization signal block based on the direction and number of the synchronization beam configured for the user equipment 100 and the distribution of other user equipment around the user equipment 100, or based on the direction of the synchronization beam configured for the user equipment and the distribution of other user equipment around the user equipment 100. If the user equipment 100 cannot obtain the distribution of other user equipment around it from other devices, and the user equipment 100 itself cannot sense the distribution of other user equipment around it, the configuration unit 110 may determine the configuration of the synchronization signal block based on the direction and number of the synchronization beam configured for the user equipment 100. For another example, since the transmission of the synchronization signal is periodic, the configuration unit 110 may determine the configuration of the synchronization signal block before the start of each synchronization signal transmission cycle. If the user equipment 100 cannot obtain the distribution of other user equipment around it from other devices, and the user equipment 100 itself cannot sense the distribution of other user equipment around it, the configuration unit 110 may use the configuration result of the synchronization signal block in the previous synchronization signal block transmission cycle.

[0106] According to an embodiment of the present disclosure, after the configuration unit 110 configures the configuration of the synchronization signal block, the user equipment 100 can use the activated synchronization beam to send the synchronization signal block. Here, the user equipment 100 can determine the coverage time of each activated synchronization beam according to the time domain position of the synchronization signal block sent by each activated synchronization beam configured by the configuration unit 110, so as to use the activated synchronization beam to send the corresponding synchronization signal block at the corresponding coverage time. For example, in Example A shown in Figure 4, after the synchronization signal transmission period starts, the coverage time of synchronization beam 0 starts, and after s1-TimeOffset SSB-r16 plus the time domain width of one S-SSB (i.e., 1 time slot), the coverage time of synchronization beam 0 ends and switches to synchronization beam 2. After s1-TimeInterval-r16 plus the time domain width of one S-SSB (i.e., 1 time slot), the coverage time of synchronization beam 2 ends and switches to synchronization beam 3, and so on.

[0107] According to an embodiment of the present disclosure, as shown in FIG1 , the user equipment 100 may further include a generation unit 140. After the configuration unit 110 configures the configuration of the synchronization signal block, the generation unit 140 may generate synchronization signal block related information, which includes the configuration of the synchronization signal block and the time domain position of the synchronization signal block. Here, the configuration of the synchronization signal block may include the activated synchronization beam of the user equipment 100 (e.g., the identification information of the synchronization beam) and the number of times the synchronization signal block is continuously transmitted using each activated synchronization beam (e.g., the number of S-SSBs or the number of time slots covered by each activated synchronization beam). The time domain position of the synchronization signal block may include the time domain position of the first synchronization signal block and the time domain interval between adjacent synchronization signal blocks. For example, the parameter s1-TimeOffset SSB-r16 may be used to represent the time domain position of the first synchronization signal block, and the parameter s1-TimeInterval-r16 may be used to represent the time domain interval between adjacent synchronization signal blocks. Optionally, the synchronization signal block related information may also include the total number of synchronization signal blocks to be transmitted within a synchronization signal transmission cycle.

[0108] Further, according to an embodiment of the present disclosure, the user equipment 100 can send synchronization signal block related information to other user equipment in the surrounding area through the communication unit 120. In this way, other user equipment can determine the coverage time of the synchronization beam corresponding to the direction in which they are located, and thus listen to the synchronization signal only within the coverage time. Specifically, after beam pairing with the user equipment 100, other user equipment can determine the synchronization beam paired with itself based on the identification information of the synchronization beam included in the synchronization signal block related information sent by the user equipment 100, and can determine the coverage time of the synchronization beam paired with itself based on the number of times the synchronization signal blocks are continuously sent using each activated synchronization beam included in the synchronization signal block related information, and the time domain position of the synchronization signal block.

[0109] According to an embodiment of the present disclosure, the user equipment 100 may use RRC signaling to carry synchronization signal block related information. Specifically, the user equipment 100 may add synchronization signal block related information in SLSS&MasterInformationBlockSidelink signaling.

[0110] According to an embodiment of the present disclosure, if other user devices lose synchronization with user device 100 after synchronization, the other user devices need to resynchronize with user device 100. In addition, since the synchronization signal block only occupies 11 RBs in the frequency domain, user device 100 can use the frequency domain resources not occupied by the synchronization signal block to transmit other reference signals, and other user devices need to monitor these other reference signals. According to an embodiment of the present disclosure, other user devices can monitor only within the coverage time of the synchronization beam paired with them, which can significantly save the energy of other user devices and enable other user devices to quickly monitor synchronization information and other reference signals.

[0111] In existing standards, when user equipment 100 transmits information omnidirectionally, if the subcarrier spacing of user equipment 100 is 60 kHz, the total number of synchronization signal blocks can be 1, 2, 4, 8, 16, or 32; if the subcarrier spacing of user equipment 100 is 120 kHz, the total number of synchronization signal blocks can be 1, 2, 4, 8, 16, 32, or 64. When user equipment 100 communicates using beams, such standards significantly reduce the number of synchronization signal transmissions within each synchronization beam. Therefore, according to embodiments of the present disclosure, it is desirable to increase the total number of synchronization signal blocks to improve the number of synchronization signal transmissions within each synchronization beam. For example, if the subcarrier spacing of user equipment 100 is 60 kHz, the maximum total number of synchronization signal blocks can be 32M; if the subcarrier spacing of user equipment 100 is 120 kHz, the maximum total number of synchronization signal blocks can be 64M. Here, M is the total number of synchronization beams configured for user equipment 100. M is a positive integer, and M can be configured by the base station of the user equipment 100, or can be configured when the user equipment 100 leaves the factory.

[0112] It can be seen that according to the embodiment of the present disclosure, the user equipment 100 can determine the configuration of the synchronization signal block of the user equipment, which includes the activated synchronization beam, and optionally the number of times the synchronization signal block is continuously sent using each activated synchronization beam. In this way, the synchronization beam used to send the synchronization signal block and the number of times the synchronization signal block is sent can be reasonably determined, so that the possibility of synchronization between user equipment is improved and the energy of the user equipment is saved. Furthermore, the configuration of the synchronization signal block and the position of the synchronization signal block in the time domain can be shared between user equipment, so as to speed up the synchronization process and make it possible to reuse the resources of the synchronization signal block to send other reference signals. In summary, according to the embodiment of the present disclosure, the synchronization process between SL UEs operating in the FR2 frequency band is optimized.

[0114] 10 is a block diagram illustrating a structure of an electronic device 1000 used as a network-side device in a wireless communication system according to an embodiment of the present disclosure. The electronic device 1000 may be a base station device.

[0115] As shown in FIG. 10 , the electronic device 1000 may include a configuration unit 1010 , a generation unit 1020 , and a communication unit 1030 .

[0116] Here, each unit of the electronic device 1000 may be included in a processing circuit.

Furthermore, the processing circuit may include various discrete functional units to perform various functions and / or operations. It should be noted that these functional units may be physical entities or logical entities, and units with different names may be implemented by the same physical entity.

[0117] According to an embodiment of the present disclosure, the configuration unit 1010 may determine the configuration of the synchronization signal block of the first user equipment based on the configuration of the synchronization beam of the first user equipment, wherein the configuration of the synchronization signal block includes an activated synchronization beam. Here, the first user equipment may be any user equipment within the service range of the electronic device 1000.

[0118] According to an embodiment of the present disclosure, the generation unit 1020 may generate configuration information of a synchronization signal block, and the electronic device 1000 may transmit the configuration information of the synchronization signal block generated by the generation unit 1020 to the first user equipment through the communication unit 1030, so that the first user equipment transmits the synchronization signal block using the activated synchronization beam to synchronize the second user equipment with the first user equipment. Here, the second user equipment may be a user equipment around the first user equipment that desires to synchronize with the first user equipment.

[0119] As described above, according to an embodiment of the present disclosure, electronic device 1000 can determine the configuration of a synchronization signal block of a user equipment, which includes an activated synchronization beam. In this way, the synchronization beam used to transmit the synchronization signal block can be reasonably determined, thereby increasing the possibility of synchronization between user equipments and optimizing the synchronization process between SL UEs operating in the FR2 frequency band.

[0120] According to an embodiment of the present disclosure, the configuration unit 1010 may determine the configuration of the synchronization signal block of the first user equipment based on the configuration of the synchronization beam of the first user equipment. The configuration of the synchronization beam of the first user equipment may include the direction of each synchronization beam of the first user equipment and the number of all synchronization beams of the first user equipment. Specifically, when the number of synchronization beams of the first user equipment is greater than a first threshold, the configuration unit 1010 may determine to activate a portion of the synchronization beams; when the number of synchronization beams of the first user equipment is less than or equal to the first threshold, the configuration unit 1010 may determine to activate all synchronization beams.

[0121] According to an embodiment of the present disclosure, the configuration of the synchronization signal block may further include the number of times the first user equipment continuously sends the synchronization signal block using each activated synchronization beam.

[0122] According to an embodiment of the present disclosure, when some synchronization beams are activated, the configuration unit 1010 can determine that the number of times the first user equipment continuously sends synchronization signal blocks using each activated synchronization beam is greater than 1; when all synchronization beams are activated, the configuration unit 1010 can determine that the number of times the synchronization signal blocks continuously send using each activated synchronization beam is equal to 1.

[0123] According to an embodiment of the present disclosure, when the number of times the first user equipment continuously transmits synchronization signal blocks using each activated synchronization beam is greater than 1, the configuration unit 1010 may determine the number of times the first user equipment continuously transmits synchronization signal blocks using each activated synchronization beam based on the number of activated synchronization beams and the total number of times synchronization signal blocks are to be transmitted. Specifically, the configuration unit 1010 may determine the value obtained by dividing the total number of times synchronization signal blocks are to be transmitted by the number of activated synchronization beams as the number of times synchronization signal blocks are continuously transmitted using each activated synchronization beam.

[0124] According to an embodiment of the present disclosure, the configuration unit 1010 may also determine the configuration of the synchronization signal block of the first user equipment according to the distribution of other user equipments around the first user equipment.

[0125] According to an embodiment of the present disclosure, the electronic device 1000 can obtain the locations of all user devices within its coverage area, thereby determining the distribution of other user devices around the first user device. In addition, the electronic device 1000 can also receive the distribution of other user devices around the first user device from a device with a sensing function, such as an RSU around the first user device. The electronic device 1000 can also receive the distribution of other user devices around the first user device obtained by the first user device through its own sensing device from the first user device.

[0126] According to an embodiment of the present disclosure, the configuration unit 1010 can determine the configuration of the synchronization signal block of the first user device based on the configuration of the synchronization beam of the first user device and the distribution of other user devices around the first user device. The configuration of the synchronization beam of the first user device may include the directions of each synchronization beam of the first user device.

[0127] Specifically, the configuration unit 1010 may determine to activate the synchronization beam in the direction where the number of other user equipments is greater than the second threshold, and not to activate the synchronization beam in the direction where the number of other user equipments is less than or equal to the second threshold.

[0128] According to an embodiment of the present disclosure, the configuration of the synchronization signal block may further include the number of times the first user equipment continuously transmits the synchronization signal block using each activated synchronization beam. Specifically, for an activated synchronization beam in a direction in which the number of other user equipment is greater than a third threshold, the configuration unit 1010 may determine that the number of times the first user equipment continuously transmits the synchronization signal block using the activated synchronization beam is greater than 1, and for an activated synchronization beam in a direction in which the number of other user equipment is less than or equal to the third threshold, the configuration unit 1010 may determine that the number of times the first user equipment continuously transmits the synchronization signal block using the activated synchronization beam is equal to 1.

[0129] According to an embodiment of the present disclosure, when the third threshold is equal to the second threshold, the configuration unit 1010 may determine that the number of times the first user equipment continuously transmits synchronization signal blocks using all activated synchronization beams is greater than 1. In this case, the configuration unit 1010 may determine the number of times the first user equipment continuously transmits synchronization signal blocks using each activated synchronization beam based on the number of activated synchronization beams and the total number of times synchronization signal blocks are to be transmitted. Specifically, the configuration unit 1010 may determine the value obtained by dividing the total number of times synchronization signal blocks are to be transmitted by the number of activated synchronization beams as the number of times synchronization signal blocks are continuously transmitted using each activated synchronization beam.

[0130] According to an embodiment of the present disclosure, the configuration unit 1010 can determine the configuration of the synchronization signal block of the first user device based on the configuration of the synchronization beam of the first user device and the distribution of other user devices around the first user device. The configuration of the synchronization beam of the first user device may include the direction of each synchronization beam of the first user device and the number of all synchronization beams.

[0131] Specifically, when the number of synchronization beams of the first user device is greater than the first threshold, the configuration unit 1010 can determine to activate the synchronization beams in the direction where the number of other user devices is greater than the second threshold, and not activate the synchronization beams in the direction where the number of other user devices is less than or equal to the second threshold; when the number of synchronization beams of the first user device is less than or equal to the first threshold, the configuration unit 1010 can determine to activate all synchronization beams.

[0132] According to an embodiment of the present disclosure, the configuration of the synchronization signal block may further include the number of times the first user equipment continuously transmits the synchronization signal block using each activated synchronization beam. Specifically, for an activated synchronization beam in a direction in which the number of other user equipment is greater than a third threshold, the configuration unit 1010 may determine that the number of times the first user equipment continuously transmits the synchronization signal block using the activated synchronization beam is greater than 1, and for an activated synchronization beam in a direction in which the number of other user equipment is less than or equal to the third threshold, the configuration unit 1010 may determine that the number of times the first user equipment continuously transmits the synchronization signal block using the activated synchronization beam is equal to 1.

[0133] In the present disclosure, the configuration unit 1010 may determine the configuration of the synchronization signal block of the first user equipment in the same manner as the configuration unit 110 described above. That is, the configuration of the synchronization signal block may be determined by the user equipment itself or by the serving base station of the user equipment.

[0134] According to an embodiment of the present disclosure, the configuration unit 1010 may utilize MAC or RRC signaling to carry the configuration of the synchronization signal block.

[0135] According to an embodiment of the present disclosure, the generation unit 1020 may periodically generate a configuration of a synchronization signal block, and the electronic device 1000 may periodically send the configuration of the synchronization signal block to the first user equipment through the communication unit 1030. The period here may be, for example, an integer multiple of the synchronization signal transmission period (160ms). For example, the electronic device 1000 may send the configuration of the synchronization signal block to the first user equipment before the start of each synchronization signal transmission period. Optionally, the generation unit 1020 may periodically generate the configuration of the synchronization signal block, and only when the configuration of the synchronization signal block generated this time is different from the configuration of the synchronization signal block generated last time, the electronic device 1000 sends the configuration of the synchronization signal block to the first user equipment through the communication unit 1030. Optionally, the generation unit 1020 may also generate the configuration of the synchronization signal block in response to a request from the first user equipment, so that the electronic device 1000 can send the configuration of the synchronization signal block to the first user equipment through the communication unit 1030.

[0136] In addition, according to an embodiment of the present disclosure, the configuration of a synchronization signal block may include an activated synchronization beam. Here, the activated synchronization beam may be represented by identification information of the synchronization beam of the first user equipment. In addition, the configuration of the synchronization signal block may also include the number of times the synchronization signal block is continuously transmitted using each activated synchronization beam. Here, the number of times the synchronization signal block is continuously transmitted may be represented by the number of synchronization signal blocks, or the number of time slots covered by the activated synchronization beam may be used to indirectly represent the number of times the synchronization signal block is continuously transmitted.

[0137] Thus, the present disclosure further provides a user equipment, comprising a processing circuit configured to: receive a synchronization signal block configuration from a base station device, the synchronization signal block configuration including an activated synchronization beam; and transmit the synchronization signal block using the activated synchronization beam to synchronize other user equipment with the user equipment. Here, the synchronization signal block configuration is determined by the base station device based on the synchronization beam configuration of the user equipment.

[0138] It can be seen that according to the embodiment of the present disclosure, the electronic device 1000 can determine the configuration of the synchronization signal blocks of the user equipment within its coverage, which includes the activated synchronization beams and, optionally, the number of times the synchronization signal blocks are continuously sent using each activated synchronization beam. In this way, the synchronization beam used to send the synchronization signal block and the number of times the synchronization signal block is sent can be reasonably determined, thereby increasing the possibility of synchronization between user equipment and saving energy of the user equipment. In summary, according to the embodiment of the present disclosure, the synchronization process between SL UEs operating in the FR2 frequency band is optimized.

[0142] As shown in FIG. 11 , in step S1110 , the configuration of the synchronization signal block of the user equipment 100 is determined according to the configuration of the synchronization beam of the user equipment 100 , wherein the configuration of the synchronization signal block includes an activated synchronization beam.

[0176] <Application examples for base stations>

[0177] (First application example)

[0178] 13 is a block diagram showing a first example of a schematic configuration of an eNB to which the technology of the present disclosure can be applied. The eNB 1300 includes one or more antennas 1310 and a base station device 1320. The base station device 1320 and each antenna 1310 can be connected to each other via an RF cable.

[0179] Each of the antennas 1310 includes a single or multiple antenna elements (such as multiple antenna elements included in a multiple-input multiple-output (MIMO) antenna) and is used for base station device 1320 to transmit and receive wireless signals. As shown in FIG13 , eNB 1300 may include multiple antennas 1310. For example, multiple antennas 1310 may be compatible with multiple frequency bands used by eNB 1300. Although FIG13 shows an example in which eNB 1300 includes multiple antennas 1310, eNB 1300 may also include a single antenna 1310.

[0180] The base station device 1320 includes a controller 1321 , a memory 1322 , a network interface 1323 , and a wireless communication interface 1325 .

[0181] The controller 1321 may be, for example, a CPU or a DSP, and operates various functions of the higher layers of the base station device 1320. For example, the controller 1321 generates data packets based on the data in the signal processed by the wireless communication interface 1325, and transmits the generated packets via the network interface 1323. The controller 1321 may bundle data from multiple baseband processors to generate bundled packets, and transmit the generated bundled packets. The controller 1321 may have logic functions for performing the following controls: the control may be radio resource control, radio bearer control, mobility management, admission control, and scheduling. The control may be performed in conjunction with a nearby eNB or core network node. The memory 1322 includes RAM and ROM, and stores programs executed by the controller 1321 and various types of control data (such as a terminal list, transmission power data, and scheduling data).

[0182] The network interface 1323 is a communication interface for connecting the base station device 1320 to the core network 1324. The controller 1321 can communicate with the core network node or another eNB via the network interface 1323. In this case, the eNB 1300 and the core network node or other eNB can be connected to each other through a logical interface (such as an S1 interface and an X2 interface). The network interface 1323 can also be a wired communication interface or a wireless communication interface for a wireless backhaul line. If the network interface 1323 is a wireless communication interface, the network interface 1323 can use a higher frequency band for wireless communication than the frequency band used by the wireless communication interface 1325.

[0183] The wireless communication interface 1325 supports any cellular communication scheme, such as Long Term Evolution (LTE) and LTE-Advanced, and provides wireless connectivity to terminals located in the cell of the eNB 1300 via the antenna 1310. The wireless communication interface 1325 may typically include, for example, a baseband (BB) processor 1326 and RF circuitry 1327. The BB processor 1326 can perform various signal processing functions, such as encoding / decoding, modulation / demodulation, and multiplexing / demultiplexing, and can handle various layers (e.g., Layer 1, Medium Access Control (MAC), Radio Link Control (RLC), and Packet Data Convergence Protocol (PDCP)). In place of the controller 1321, the BB processor 1326 may have some or all of the aforementioned logical functions. The BB processor 1326 may be a memory that stores communication control programs, or a module including a processor configured to execute programs and associated circuitry. Program updates can modify the functionality of the BB processor 1326. This module may be a card or blade inserted into a slot in the base station device 1320. Alternatively, the module may be a chip mounted on the card or blade. Meanwhile, the RF circuit 1327 may include, for example, a mixer, a filter, and an amplifier, and transmit and receive wireless signals via the antenna 1310 .

[0184] As shown in FIG13 , the wireless communication interface 1325 may include multiple BB processors 1326. For example, multiple BB processors 1326 may be compatible with multiple frequency bands used by the eNB 1300. As shown in FIG13 , the wireless communication interface 1325 may include multiple RF circuits 1327. For example, multiple RF circuits 1327 may be compatible with multiple antenna elements. Although FIG13 illustrates an example in which the wireless communication interface 1325 includes multiple BB processors 1326 and multiple RF circuits 1327, the wireless communication interface 1325 may also include a single BB processor 1326 or a single RF circuit 1327.

As shown in FIG. 14, the wireless communication interface 1455 may include multiple BB processors 1456. For example, the multiple BB processors 1456 may be compatible with multiple frequency bands used by the eNB 1430.
