Description

[0001] This application claims priority to Chinese Patent Application No. 202010084841.0, filed on February 10, 2020, entitled "Electronic Device and Method for Wireless Communication, Computer-Readable Storage Medium", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of wireless communication technology, and more specifically to the technology of using pre-configured resources. More specifically, it relates to an electronic device and method for wireless communication, as well as a computer-readable storage medium. Background Technology

[0003] With the rapid increase in the number of cars, traffic accidents caused by automobiles are occurring frequently. To avoid further huge losses caused by traffic accidents, V2X (Vehicle-to-Everything) vehicle-to-everything (V2X) technology has developed rapidly. V2X can provide safety warnings for vehicles, avoid congested and dangerous road sections, improve driving safety, and reduce traffic accidents. Existing V2X technologies can solve communication problems between vehicles, between vehicles and pedestrians, between vehicles and network infrastructure, and between vehicles and the network. Among current V2X technologies, LTE-V2X is a relatively mainstream technology, which can obtain relatively safe, reliable, and efficient communication capabilities in high-speed mobility and can effectively utilize relevant resources. With the development of 5G-NR research and standardization work, NR-V2X has also become a hot research topic.

[0004] In NR-V2X, the resources allocated by the base station to the User Equipment (UE) are divided into several categories. One category is dynamically scheduled resources, and the other is pre-configured resources. Pre-configured resources are further divided into two types: Type 1 pre-configured resources and Type 2 pre-configured resources. The main difference between these two types is as follows: For Type 1 pre-configured resources, the UE can use them after obtaining the time-frequency location of the corresponding resource through Radio Resources Control (RRC) signaling, until the RRC notifies it to stop using them (or the maximum available time is reached); for Type 2 pre-configured resources, after the UE obtains its time-frequency location through RRC signaling, the base station still needs to activate / deactivate them through Downlink Control Information (DCI) transmitted on the Physical Downlink Control Channel (PDCCH).

[0005] In LTE-V2X, if a UE detects a physical layer problem, it will no longer be able to use the pre-configured resources. Instead, the UE will communicate on an exceptional resource pool until an RRC reconnection is completed or the UE switches from the first transmission mode (mode 1) where resources are allocated by the base station to a second transmission mode (mode 2) where resources are selected by the UE. The resource allocation mode used on the exceptional resource pool is a random allocation mode, which can easily lead to collisions during communication, reducing communication reliability. In NR-V2X, however, some services require reliability as high as 99.999%. Summary of the Invention

[0033] <First Embodiment>

[0034] Figure 1 A functional block diagram of an electronic device 100 for wireless communication according to an embodiment of this application is shown, such as... Figure 1 As shown, the electronic device 100 includes: a first determining unit 101 configured to determine that a UE performing transmission using pre-configured resources in a pre-configured resource pool has encountered a physical layer problem; and a second determining unit 102 configured to determine the length of time the UE can continue to use the pre-configured resources based on the transmission quality requirements of the data packet to be sent.

[0035] The first determining unit 101 and the second determining unit 102 can be implemented by one or more processing circuits, such as chips. Furthermore, it should be understood that... Figure 1The functional units in the device shown are logical modules divided according to the specific functions they implement, rather than being used to restrict the specific implementation method.

[0036] Electronic device 100 may be located on the UE side or communicatively connected to the UE. It should also be noted that electronic device 100 may be implemented at the chip level or at the device level. For example, electronic device 100 may function as the UE itself and may also include external devices such as memory and transceivers (not shown). Memory may be used to store programs and related data information that the UE needs to execute to perform various functions. Transceivers may include one or more communication interfaces to support communication with different devices (e.g., base stations, other user equipment, etc.), and the specific implementation of the transceiver is not limited here.

[0037] It should be noted that the embodiments described herein can be applied to NR-V2X scenarios to improve communication reliability; however, this is not limiting, but can be applied to any other situation with similar requirements. In the following description, for ease of understanding, NR-V2X applications will be used as examples where appropriate.

[0038] As mentioned earlier, when a physical layer problem occurs, it means that the UE may no longer be able to use the pre-configured resources, thus requiring the UE to perform operations such as cell reselection. During the transition period before re-establishing the connection (also known as the problem period), it is desirable to ensure the continuity and reliability of communication.

[0039] Specifically, the first determining unit 101 determines a physical layer problem when, for example, a predetermined number of out-of-sync indications are received consecutively at the lower layer without cell reselection or handover. This is not limiting; the first determining unit 101 can utilize various techniques to determine the occurrence of a physical layer problem.

[0040] In one example, when a physical layer problem is detected, the existing timer T310 starts counting down. If the physical layer problem is resolved before timer T310 expires, the UE can continue communicating using the previously pre-configured resources; otherwise, a radio link failure may be detected, and the existing timer T311 starts counting down and cell reselection occurs.

[0041] In this embodiment, when a physical layer problem occurs, the UE can continue to use pre-configured resources for communication for a period of time while waiting for the physical layer problem to resolve. For example, the length of time the UE can continue to use pre-configured resources can be determined based on the transmission quality requirements of the data packets to be sent. If the physical layer problem is still not resolved after this period of time, the UE can switch to the abnormal resource pool for communication. A schematic flowchart of this UE operation is shown below. Figure 2 As shown. Note that the physical layer issues mentioned here can also include cases of wireless link failure.

[0042] Transmission quality requirements may include one or more of the following: reliability requirements, priority requirements. Transmission quality requirements indicate the importance of data packets. For example, the higher the transmission quality requirement of a data packet to be sent, the longer the UE can continue to use pre-configured resources to ensure reliable data transmission.

[0043] For example, existing timers such as T304, T310, and T311 can be used to measure the duration of time. Alternatively / supplementarily, new timers can also be set to measure the duration of time.

[0044] In one example, the second determining unit 102 determines the time length corresponding to the transmission quality requirement based on the mapping relationship between the transmission quality requirement and the time length of the data packet to be sent. For ease of understanding, the following will refer to... Figure 3 An example describing this mapping relationship.

[0045] Figure 3 This shows the ProSe Per-Packet Reliability (PPPR) requirement and time length T. val An example of the mapping relationship between them. When PPPR is required to be one of 1-3, T val A value of 0 means that the UE is not allowed to continue using pre-configured resources when a physical layer problem occurs. When the PPPR requirement is one of 4-6, T... val T310 means that when a physical layer problem occurs, the UE can continue to use pre-configured resources until timer T310 expires. If the physical layer problem is not resolved or a radio link failure occurs when T310 expires, communication is switched to the abnormal resource pool. When the PPPR requirement is one of 7-8, T... val For T310+T311, that is, when a physical layer problem occurs (and consequently a radio link failure), the UE can continue to use pre-configured resources until timer T310 expires and then T311 expires. val If cell reselection is not completed afterward, communication will be switched to the abnormal resource pool.

[0046] exist Figure 3 The example uses existing timers T310 and T311, but this is just an example and not a limitation. The duration and necessary timers can be set as needed.

[0047] Figure 4 Another functional module block diagram of the electronic device 100 is shown, in addition to Figure 1In addition to the various units shown, the electronic device 100 also includes a transceiver unit 103 for performing related transceiver functions. For example, the transceiver unit 103 is configured to obtain the aforementioned mapping relationship from the base station in advance. The transceiver unit 103 may obtain the mapping relationship via RRC signaling or a System Information Block (SIB).

[0048] In addition, the transceiver unit 103 is also configured to report the transmission quality requirements of the data packets to be sent to the base station, which may be performed, for example, when requesting pre-configured resources from the base station.

[0049] Figure 5 An example of the information flow between the base station and the UE is illustrated. First, the base station informs the UE of the mapping relationship in advance, for example, via RRC signaling or SIB. The UE then requests pre-configured resources from the base station, for example, via a Scheduling Request / Buffer State Report (BSR), where the SR / BSR may include the transmission quality requirements of the data packets to be transmitted, such as PPPR. Subsequently, the UE performs transmission on the pre-configured resources allocated by the base station. When a physical layer problem is detected, the UE determines the length of time it can continue to use the pre-configured resources based on the obtained mapping relationship and the transmission quality requirements of the data packets to be transmitted and starts a corresponding timer. At the same time, the base station also determines this length of time and starts a corresponding timer. In other words, some functions of the electronic device 100 can also be performed on the base station side.

[0050] In one example, the second determining unit 102 is further configured to determine that the UE's transmission radio link has failed and that the UE performs cell reselection. If the new base station connected to after reselection is different from the base station connected to before reselection, the transceiver unit 103 is further configured to provide the new base station with the original base station's identifier (ID) and the UE's identifier within the original base station. Thus, the new base station can notify the original base station, for example, via an X2 interface, of the release of pre-configured resources previously allocated to the UE.

[0051] Figure 6 The diagram illustrates an operational flow of this example. During communication using pre-configured resources, the UE detects a radio link failure and performs cell reselection. After reselection, it checks if the new base station is the same as the original base station. If they are the same, no operation is performed. Otherwise, the original base station's ID and the UE's ID within the original base station are reported to the new base station. The new base station identifies the original base station based on its ID and notifies it of the UE's ID within the original base station. Upon receiving this ID, the original base station releases the pre-configured resources previously allocated to the UE.

[0052] Accordingly, Figure 7An example of the information flow between the base station and the UE is shown. Signaling interactions, as described above, exist between the UE and the new base station, and between the new base station and the original base station.

[0053] This allows the pre-configured resources of the original cell to be released in a timely manner after the UE performs cell reselection, thereby improving spectrum utilization.

[0054] Note that if the mapping relationship of the new base station is different from that of the original base station, the UE will obtain the new mapping relationship from the new base station for updating; otherwise, if the original base station and the new base station share the mapping relationship, the UE can continue to use the original mapping relationship.

[0055] As a concrete example, suppose the UE is currently connected to cell A, and according to the mapping relationship, it can be known the length of time T during which the UE can continue to use the pre-configured resources when a physical layer problem occurs. val =T310 + T311. If the UE detects a physical layer problem (time starts at T310) and subsequently detects a radio link failure (time starts at T311), the UE initiates cell reselection. If the UE reselects to cell B instead of cell A, after completing the RRC reconnection, the UE can report the ID of cell A, such as the Physical Cell Identifier (PCI), and the UE's identifier in cell A, such as the C-RNTI value, via PUCCH. Cell B will provide the C-RNTI value to the base station of cell A through an inter-cell interface, such as the X2 interface, to notify cell A that the user has reselected to cell B, thus allowing cell A to release the pre-configured resources associated with the UE. Upon receiving this notification, cell A releases the corresponding resources.

[0056] In summary, the electronic device 100 according to this embodiment can effectively improve the communication reliability of user equipment using pre-configured resources for transmission during the problem period when physical layer problems occur, and can promptly release the pre-configured resources of the original cell when reselection occurs, thereby improving resource utilization efficiency.

[0057] Note that the information flow diagrams described above are merely illustrative and not restrictive.

[0058] <Second Embodiment>

[0059] In this embodiment, the proposed solution can also be applied to handover scenarios. For example, in NR-V2X scenarios, if a user's vehicle moves rapidly, handover between different cells may occur. Given the high reliability required in NR-V2X scenarios, it is necessary to ensure the reliability of communication during handover. An example of improving communication reliability during handover will be described below.

[0060] Reference Figure 1 The first determining unit 101 of the electronic device 100 is configured to determine that the UE needs to perform a cross-cell handover from the currently connected first base station to the second base station, wherein, during the handover process, the UE uses pre-configured resources in the pre-configured resource pool of the second base station. Correspondingly, the second determining unit 102 determines the length of time the UE can use the pre-configured resources based on the transmission quality requirements of the data packets to be transmitted.

[0061] When the first base station and the second base station use the same mapping relationship, the second determining unit 102 determines the duration for which the UE can use the pre-configured resources of the second base station based on the existing mapping relationship. For example, this duration can be measured using an existing timer such as T304, or it can be measured using a newly set timer.

[0062] The indication that the first base station and the second base station use the same mapping relationship can be included in the handover command from the first base station.

[0063] If the first base station and the second base station do not use the same mapping relationship, the transceiver unit 103 can be configured to obtain the mapping relationship of the second base station via a handover command from the first base station. The second determining unit 102 determines the length of time the UE can use the pre-configured resources of the second base station based on the newly obtained mapping relationship.

[0064] Alternatively, the transceiver unit 103 can be configured to obtain information about the duration for which the UE can use the pre-configured resources of the second base station via a handover command. In this case, the UE can obtain the mapping relationship of the second base station from the second base station after a successful handover.

[0065] In this way, during handover, the pre-configured resources of the second base station can be used for communication instead of the abnormal resource pool, thus improving communication reliability.

[0066] If the handover is successful, the UE can continue to use the pre-configured resources of the second base station for communication. On the other hand, if the handover fails and the UE reconnects to a third base station different from the second base station, the transceiver unit 103 is also configured to provide the third base station with the identifier of the second base station and the UE's identifier within the second base station. Similarly, the third base station will identify the second base station using its identifier and send the UE's identifier within the second base station to the second base station, thereby causing the second base station to release the corresponding pre-configured resources.

[0067] In summary, the electronic device 200 according to this embodiment can effectively improve the communication reliability of user equipment using pre-configured resources for transmission during handover and timely release of the pre-configured resources of the original cell when reselection occurs, thereby improving resource utilization efficiency.

[0068] It should be understood that the solutions in the first embodiment and the second embodiment can be implemented individually or in combination. That is, the electronic device 100 can be applied to one of the scenarios where physical layer problems occur and the scenario of handover, or it can be applied to both scenarios. This is not limiting.

[0069] <Third Embodiment>

[0070] Figure 8 A functional block diagram of an electronic device 200 according to another embodiment of this application is shown, such as Figure 8 As shown, the electronic device 200 includes: a providing unit 201 configured to provide a UE that wants to perform transmission using pre-configured resources in a pre-configured resource pool with a mapping relationship between the transmission quality requirements of the data packet to be transmitted and the length of time the UE can continue to use the pre-configured resource after a physical layer problem is detected; and a configuration unit 202 configured to configure the pre-configured resource for the UE.

[0071] The providing unit 201 and the configuration unit 202 can be implemented by one or more processing circuits, which can be implemented as chips, for example. Furthermore, it should be understood that... Figure 8 The functional units in the device shown are logical modules divided according to the specific functions they implement, rather than being used to restrict the specific implementation method.

[0072] Electronic device 200 can be located on the base station side or communicatively connected to the base station. It should also be noted that electronic device 200 can be implemented at the chip level or at the device level. For example, electronic device 200 can function as the base station itself and may also include external devices such as memory and transceivers (not shown). The memory can be used to store programs and related data information that the base station needs to execute to implement various functions. The transceiver may include one or more communication interfaces to support communication with different devices (e.g., user equipment, other base stations, etc.), and there is no specific limitation on the implementation form of the transceiver.

[0073] For example, the providing unit 201 can be configured to provide the mapping relationship to the UE via RRC signaling or SIB. A detailed description of this mapping relationship has been given in the first embodiment and will not be repeated here.

[0074] Transmission quality requirements may include one or more of the following: reliability requirements, priority requirements. The mapping relationship can be set so that the higher the transmission quality requirement of the data packet to be sent, the longer the UE can continue to use the pre-configured resources.

[0075] In addition, such as Figure 9As shown, the electronic device 200 may further include a receiving unit 203 configured to receive the transmission quality requirements of the data packets to be transmitted by the UE from the UE. For example, the transmission quality requirements may be included in the UE's pre-configured resource request, such as an SR / BSR.

[0076] In the event of a physical layer problem, for example, configuration unit 202 can also determine the length of time the UE can continue to use the pre-configured resources based on the mapping relationship and the transmission quality requirements of the data packets, and start the corresponding timer.

[0077] In one example, electronic device 200 corresponds to the first base station to which the UE was connected before reselection. If the UE reselects to another cell, receiving unit 203 is also configured to receive information about the UE's identification in the first base station and indication information indicating that the UE has reselected to the second base station from the corresponding second base station. Receiving unit 203 can receive this information and the indication information via the X2 interface. In this case, configuration unit 202 releases the pre-configured resources previously configured for the UE.

[0078] If the first base station and the second base station share the mapping relationship, the UE can continue to use the previous mapping relationship. Otherwise, the second base station will send a new mapping relationship to the UE.

[0079] It should be noted that the above scenario can occur in both cell reselection and handover scenarios. In this scenario, after reselection, the UE reports the ID of the first base station and its ID within the first base station to the second base station. The second base station identifies the first base station based on its ID and notifies it of the UE's ID within the first base station and the fact that the UE has reselected to the second base station, thus enabling the first base station to release the UE's previously pre-configured resources.

[0080] Specifically, in a handover scenario, for example, if a UE attempts to hand over to a first base station that is different from the second base station but the handover fails, and subsequently reconnects to the second base station via reselection, then the first base station is the base station it was connected to before the reselection. Similarly, the UE reports the ID of the first base station and its ID within the first base station to the second base station. The second base station identifies the first base station based on its ID and notifies the first base station to release the UE's previously pre-configured resources.

[0081] In another example, in a handover scenario, electronic device 200 corresponds to the first base station currently connected to the UE, and providing unit 201 is further configured to send a handover command to the UE instructing the UE to switch from the first base station to a second base station. For example, the handover command may include one of the following: an indication that the mapping relationship of the first base station and the mapping relationship of the second base station are the same; the mapping relationship of the second base station; or information on the length of time the UE can use the pre-configured resources of the second base station.

[0082] If the mapping relationship between the first base station and the second base station is the same, the UE can determine the length of time it can use the pre-configured resources of the second base station based on the previously obtained mapping relationship of the first base station. Otherwise, the UE can determine the length of time based on the mapping relationship of the second base station; or it can determine the length of time directly based on the received information. In this case, the UE can obtain a new mapping relationship from the second base station after the handover is successful.

[0083] In another example, the UE reselects from its original base station to the base station corresponding to electronic device 200. The receiving unit 203 is further configured to receive the identifier of the original base station and the UE's identifier within the original base station from the UE. In this case, the providing unit 201 is configured to send information about the UE's identifier within the original base station and an indication that the UE has switched to this base station to the original base station. For example, this information and the indication can be sent via the X2 interface.

[0084] In a handover scenario, as mentioned above, the original base station is the base station that the UE attempted to hand over to but ultimately failed.

[0085] The relevant information flow in this embodiment has been given in detail in the first embodiment and will not be repeated here.

[0086] In summary, the electronic device 200 according to this embodiment can effectively improve the communication reliability of user equipment using pre-configured resources for transmission during the transition period when physical layer problems occur or during handover, and can promptly release the pre-configured resources of the original cell when reselection occurs, thereby improving resource utilization efficiency.

[0087] <Fourth Embodiment>

[0088] In the process of describing the electronic device for wireless communication in the above embodiments, some processes or methods have obviously been disclosed. Hereinafter, without repeating some details already discussed above, a summary of these methods is given. However, it should be noted that although these methods are disclosed in the description of the electronic device for wireless communication, they do not necessarily employ or are performed by the components described. For example, the embodiments of the electronic device for wireless communication may be implemented partially or entirely using hardware and / or firmware, while the methods for wireless communication discussed below may be implemented entirely by computer-executable programs, although these methods may also employ the hardware and / or firmware of the electronic device for wireless communication.

[0089] Figure 10A flowchart of a method for wireless communication according to an embodiment of this application is shown. The method includes: determining that a physical layer problem has occurred in the transmission of a UE performing a transmission using pre-configured resources in a pre-configured resource pool (S11); and determining the length of time the UE can continue to use the pre-configured resources based on the transmission quality requirements of the data packet to be transmitted (S12). The method is performed, for example, on the UE side.

[0090] For example, transmission quality requirements may include one or more of the following: reliability requirements, priority requirements. The higher the transmission quality requirement of the data packets to be sent, the longer the UE can continue to use the pre-configured resources.

[0091] In step S12, the time length corresponding to the transmission quality requirement can be determined based on the mapping relationship between the transmission quality requirement and the time length of the data packet to be sent. This mapping relationship can be obtained in advance from the base station, for example, via RRC signaling or SIB. The time length can be measured using an existing timer or by setting a new timer. Existing timers include, for example, one or more of the following: T304, T310, T311.

[0092] In addition, although not shown in the figure, the above method may also include the following steps: reporting the transmission quality requirements of the data packets to be sent when requesting pre-configured resources from the base station.

[0093] In one example, the above method may further include: determining that the radio link of the UE's transmission has failed and that the UE performs cell reselection; and, if the new base station connected to after reselection is different from the original base station connected to before reselection, providing the new base station with the identifier of the original base station and the identifier of the UE in the original base station.

[0094] In another example, the above method may further include: determining that the UE needs to switch from the currently connected first base station to the second base station, wherein the UE uses pre-configured resources in the pre-configured resource pool of the second base station during the handover process, and wherein, if the first base station and the second base station use the same mapping relationship, the length of time for which the UE can use the pre-configured resources of the second base station is determined based on the mapping relationship.

[0095] If the first base station and the second base station do not use the same mapping relationship, the mapping relationship of the second base station can be obtained through the handover command from the first base station, or the information on the length of time the UE can use the pre-configured resources of the second base station can be obtained through the handover command.

[0096] In the event of a failed handover and the UE reconnecting to a third base station that is different from the second base station after reselection, the identifier of the second base station and the identifier of the UE in the second base station are provided to the third base station.

[0097] Figure 11 A flowchart of a method for wireless communication according to another embodiment of this application is shown. The method includes: providing a UE that wants to perform a transmission using pre-configured resources in a pre-configured resource pool with a mapping relationship between the transmission quality requirements of a data packet to be transmitted and the length of time the UE can continue to use the pre-configured resources after a physical layer problem is detected (S21); and configuring the pre-configured resources for the UE (S22). This method can be performed, for example, at the base station side.

[0098] Similarly, transmission quality requirements may include one or more of the following: reliability requirements, priority requirements. The mapping relationship can be configured such that the higher the transmission quality requirement of the data packet to be sent, the longer the UE can continue to use the pre-configured resources. In step S21, the mapping relationship can be provided to the UE via RRC signaling or SIB.

[0099] In one example, the UE connects to a first base station before reselection. The method further includes receiving information about the UE's identifier in the first base station and indication information indicating that the UE has reselected to the second base station after reselection. Upon receiving this information, previously configured resources for the UE can be released. This information can be received, for example, via the X2 interface.

[0100] In another example, the method described above also includes sending a handover command to the UE instructing the UE to switch from the currently connected first base station to the second base station, wherein the handover command includes one of the following: an indication that the mapping relationship of the first base station and the mapping relationship of the second base station are the same; the mapping relationship of the second base station; or information on the length of time the UE can use the pre-configured resources of the second base station.

[0101] In another example, when the UE reselects from its original base station to a new base station, the method further includes receiving the identifier of the original base station and the UE's identifier within the original base station from the UE, and sending information about the UE's identifier within the original base station and an indication that the UE has switched to the new base station to the original base station. This information is sent, for example, via the X2 interface.

[0102] The methods described above correspond to the electronic device 100 described in the first and second embodiments and the electronic device 200 described in the third embodiment, respectively. Specific details can be found in the descriptions at the corresponding locations above, and will not be repeated here. Note that the above methods can be used in combination or individually.

[0103] The technology disclosed herein can be applied to a variety of products.

[0104] For example, electronic device 200 can be implemented as various base stations. A base station can be implemented as any type of evolved NodeB (eNB) or gNB (5G base station). eNBs include, for example, macro eNBs and small eNBs. A small eNB can be an eNB covering a cell smaller than a macro cell, such as a pico eNB, micro eNB, and femtocell eNB. A similar situation can occur with gNBs. Alternatively, a base station can be implemented as any other type of base station, such as a NodeB and a Base Transceiver Station (BTS). A base station can include: a subject configured to control wireless communication (also called base station equipment); and one or more remote radio heads (RRHs) located in a different location from the subject. Furthermore, various types of user equipment can operate as base stations by temporarily or semi-persistently performing base station functions.

[0105] Electronic device 100 can be implemented as various user devices. User devices can be implemented as mobile terminals (such as smartphones, tablet PCs, laptop PCs, portable gaming terminals, portable / dongle-type mobile routers, and digital camera devices) or in-vehicle terminals (such as car navigation devices). User devices can also be implemented as terminals performing machine-to-machine (M2M) communication (also known as machine-type communication (MTC) terminals). Furthermore, user devices can be wireless communication modules (such as integrated circuit modules comprising a single chip) installed on each of the aforementioned terminals.

[0107] (First application example)

[0108] Figure 12 This is a block diagram illustrating a first example of a schematic configuration of an eNB or gNB to which the technologies of this disclosure can be applied. Note that the following description uses an eNB as an example, but it can also be applied to a gNB. The eNB 800 includes one or more antennas 810 and a base station device 820. The base station device 820 and each antenna 810 can be connected to each other via RF cables.

[0109] Each of the antennas 810 includes one or more antenna elements (such as multiple antenna elements included in a multiple-input multiple-output (MIMO) antenna) and is used by the base station equipment 820 to transmit and receive wireless signals. Figure 12 As shown, the eNB 800 may include multiple antennas 810. For example, the multiple antennas 810 may be compatible with multiple frequency bands used by the eNB 800. Although Figure 12 An example is shown in which the eNB 800 includes multiple antennas 810, but the eNB 800 may also include a single antenna 810.

[0110] The base station equipment 820 includes a controller 821, a memory 822, a network interface 823, and a wireless communication interface 825.

[0111] The controller 821 can be, for example, a CPU or a DSP, and operates various higher-level functions of the base station equipment 820. For example, the controller 821 generates data packets based on data in signals processed by the wireless communication interface 825, and transmits the generated packets via the network interface 823. The controller 821 can bundle data from multiple baseband processors to generate bundled packets and transmit the generated bundled packets. The controller 821 may have logical functions that perform controls such as radio resource control, radio bearer control, mobility management, admission control, and scheduling. This control can be performed in conjunction with nearby eNBs or core network nodes. The memory 822 includes RAM and ROM, and stores programs executed by the controller 821 and various types of control data (such as terminal lists, transmission power data, and scheduling data).

[0112] Network interface 823 is a communication interface used to connect base station equipment 820 to core network 824. Controller 821 can communicate with core network nodes or other eNBs via network interface 823. In this case, eNB 800 and core network nodes or other eNBs can be connected to each other through logical interfaces (such as S1 and X2 interfaces). Network interface 823 can also be a wired communication interface or a wireless communication interface for wireless backhaul. If network interface 823 is a wireless communication interface, it can use a higher frequency band for wireless communication compared to the frequency band used by wireless communication interface 825.

[0113] The wireless communication interface 825 supports any cellular communication scheme (such as LTE and LTE-Advanced) and provides wireless connectivity to terminals located in the cell of eNB 800 via antenna 810. The wireless communication interface 825 typically includes, for example, a baseband (BB) processor 826 and RF circuitry 827. The BB processor 826 can perform, for example, encoding / decoding, modulation / demodulation, and multiplexing / demultiplexing, and performs various types of signal processing at layers such as L1, Media Access Control (MAC), Radio Link Control (RLC), and Packet Data Convergence Protocol (PDCP). Instead of controller 821, the BB processor 826 may have some or all of the above-described logical functions. The BB processor 826 may be a memory storing communication control programs, or a module including a processor and associated circuitry configured to execute programs. Updates can change the functionality of the BB processor 826. The module may be a card or blade inserted into a slot in base station equipment 820. Alternatively, the module may be a chip mounted on a card or blade. Meanwhile, the RF circuit 827 may include, for example, a mixer, a filter, and an amplifier, and transmits and receives wireless signals via the antenna 810.

[0114] like Figure 12 As shown, the wireless communication interface 825 may include multiple BB processors 826. For example, the multiple BB processors 826 may be compatible with multiple frequency bands used by the eNB 800. Figure 12 As shown, the wireless communication interface 825 may include multiple RF circuits 827. For example, the multiple RF circuits 827 may be compatible with multiple antenna elements. Although Figure 12 An example is shown in which the wireless communication interface 825 includes multiple BB processors 826 and multiple RF circuits 827, but the wireless communication interface 825 may also include a single BB processor 826 or a single RF circuit 827.

[0115] exist Figure 12 In the eNB 800 shown, the providing unit 201 and receiving unit 203 of the electronic device 200 can be implemented by the wireless communication interface 825. At least a portion of the functions can also be implemented by the controller 821. For example, the controller 821 can improve the reliability of UE communication during transition phases such as physical layer problems or handover by performing the functions of the providing unit 201, the configuration unit 202, and the receiving unit 203.

[0119] The base station equipment 850 includes a controller 851, a memory 852, a network interface 853, a wireless communication interface 855, and a connection interface 857. The controller 851, memory 852, and network interface 853 are connected to a reference... Figure 12 The controller 821, memory 822, and network interface 823 described are the same.

[0120] The wireless communication interface 855 supports any cellular communication scheme (such as LTE and LTE-Advanced) and provides wireless communication to terminals located in the sector corresponding to the RRH 860 via the RRH 860 and antenna 840. The wireless communication interface 855 may typically include, for example, a BB processor 856. In addition to the BB processor 856 being connected to the RF circuitry 864 of the RRH 860 via a connection interface 857, the BB processor 856 is connected to the reference... Figure 12 The described BB processor 826 is the same. Figure 13 As shown, the wireless communication interface 855 may include multiple BB processors 856. For example, the multiple BB processors 856 may be compatible with multiple frequency bands used by the eNB 830. Although Figure 13 An example is shown in which the wireless communication interface 855 includes multiple BB processors 856, but the wireless communication interface 855 may also include a single BB processor 856.

[0121] Connection interface 857 is an interface for connecting base station device 850 (wireless communication interface 855) to RRH 860. Connection interface 857 can also be a communication module for connecting base station device 850 (wireless communication interface 855) to the aforementioned high-speed line of RRH 860.

[0122] The RRH 860 includes a connectivity interface 861 and a wireless communication interface 863.

[0123] Connection interface 861 is an interface for connecting RRH 860 (wireless communication interface 863) to base station equipment 850. Connection interface 861 can also be a communication module for communication in the aforementioned high-speed line.

[0124] The wireless communication interface 863 transmits and receives wireless signals via antenna 840. The wireless communication interface 863 typically includes, for example, RF circuitry 864. RF circuitry 864 may include, for example, a mixer, a filter, and an amplifier, and transmits and receives wireless signals via antenna 840. Figure 13 As shown, the wireless communication interface 863 may include multiple RF circuits 864. For example, the multiple RF circuits 864 may support multiple antenna elements. Although Figure 13 An example is shown in which the wireless communication interface 863 includes multiple RF circuits 864, but the wireless communication interface 863 may also include a single RF circuit 864.

[0125] exist Figure 13 In the eNB 830 shown, the providing unit 201 and receiving unit 203 of the electronic device 200 can be implemented by the wireless communication interface 855 and / or the wireless communication interface 863. At least a portion of the functions can also be implemented by the controller 851. For example, the controller 851 can improve the reliability of UE communication during transition phases such as physical layer problems or handover by performing the functions of the providing unit 201, the configuration unit 202, and the receiving unit 203.
