Description

Electronic device supporting dual connectivity and its operation method {ELECTRONIC DEVICE FOR PROVIDING DUAL CONNECTIVY AND METHOD FOR OPERATING THEREOF}

Various embodiments of the present disclosure relate to an electronic device supporting dual connectivity and a method of operating the same.

With the recent development of mobile communication technology, as the use of portable terminals having various functions has become common, efforts to develop a 5G communication system have been made to meet the increasing demand for wireless data traffic. In addition to the high frequency band used in 3G and LTE, the 5G communication system is also being considered for implementation in the ultra high frequency band in order to achieve a high data rate and to provide a faster data rate.

As a method of implementing 5G communication, a stand alone (SA) method and a non-stand alone (NSA) method are being considered. Among them, the NSA method may be a method of using a new radio (NR) system together with an existing LTE system. In the NSA scheme, the user terminal can use not only the eNB of the LTE system, but also the gNB (or SgNB) of the NR system. A technology that enables a user terminal to enable heterogeneous communication systems may be referred to as dual connectivity.

Dual connectivity was initially proposed by 3GPP release-12, and at the time of the initial proposal, dual connectivity using the 3.5 GHz frequency band as a small cell in addition to the LTE system was proposed. It is under discussion that the 5G NSA scheme is implemented by using the dual connectivity proposed by 3GPP release-12, using the LTE system as a master node, and using the NR system as a secondary node.

User equipment (UE) may set up a split bearer in a dual connectivity environment. When a split bearer is configured for UL (uplink), the UE may transmit data through at least one of both paths of a path based on a main cell group (MCG) and a path based on a secondary cell group (SCG). When the split bearer is configured, the UE may set one of the MCG-based path and the SCG-based path as a primary path, and set the other path as a secondary path. The UE may transmit data to the base station through a main path, for example, when the data to be transmitted is less than a threshold (eg, an uplink-data split threshold). In this case, data may not be transmitted/received through the secondary path for a preset time (eg, DRX inactivity timer), and an entity based on the secondary path may enter a connected mode discontinuous reception (CDRX) state.

Even while the entity based on the secondary path is in the CDRX state, the UE can transmit transmission data through the primary path. The UE may have to receive received data corresponding to the transmitted data. Meanwhile, the main path of the UL and the path of the DL may be set differently. For example, when the SCG-based path is set as the main path of UL, the UE may set the MCG-based path as the DL path. In this case, the MCG base station may wait until the on-period of the UE arrives and then transmit the received data to the UE. For example, even though the secondary path is set as the path of the DL, when the secondary path is in the CDRX state, there may be a time delay for the UE to receive the received data.

The electronic device and its operation method according to various embodiments may transmit data of a designated type through a secondary path based on transmission data through a primary path.

By arranging the third RFIC 226 and the antenna 248 on the same substrate, it is possible to reduce the length of the transmission line therebetween. This can reduce loss (eg, attenuation) of a signal in a high-frequency band (eg, about 6 GHz to about 60 GHz) used for communication in a 5G network, for example. Accordingly, the electronic device 101 may improve the quality or speed of communication with the second network 294 (eg, a 5G network).

For example, in various embodiments of the present disclosure, when the UE performs a specific operation, it may mean that at least one element included in the electronic device 101 performs a specific operation.

According to various embodiments, the MCG may correspond to, for example, a main node (MN) of FIG. 3A, and the SCG may correspond to, for example, a secondary node (SN) of FIG. 3A. When a node for performing communication is determined, the UE 400 may set various entities shown in FIG. 4 to communicate with the determined node (eg, a base station). The entities 401, 402, and 403 of the PDCP layer receive data (e.g., PDCP SDU corresponding to an IP packet) and convert converted data (e.g., PDCP protocol data unit (PDU)) reflecting additional information (e.g., header information).

5A is a diagram illustrating an uplink path between a UE and base stations according to various embodiments.

The UE 510 (eg, the electronic device 101) according to various embodiments may perform communication with the base stations 520a and 520b based on the split bearer in FIG. 5A. Accordingly, transmission data (eg, IP packets) to be transmitted from the UE 510 to the base stations 520a and 520b are transmitted via the second PDCP entity 541 to the second RLC entity 543 and the second MAC entity ( 545) or the first RLC entity 542 and the first MAC entity 544. For example, the first RLC entity 542 and the first MAC entity 544 may be associated with a first network, and the second RLC entity 543 and the second MAC entity 545 are associated with a second network. Can be. The first BS 520a may configure a first PDCP entity 521a, a first RLC entity 522a, and a first MAC entity 523a. The second BS 520b may configure a second PDCP entity 521b, a second RLC entity 522b, and a second MAC entity 523b. A path associated with the second RCL entity 543 and the second MAC entity 545 of the UE 510 may be a primary path 531, and the first RLC entity 542 and the first MAC entity A path associated with 544 may be a secondary path 532. Here, the first PDCP entity 521a may be implemented in the same manner as the second PDCP entity 521b. For example, for the implementation of EN-DC, when the BS 520a is an LTE BS, the first PDCP entity 521a may be set as an NR PDCP entity. In various embodiments, a specific PDCP entity (eg, NR PDCP entity) may be in BS 520a, or may be in BS 520b. When a split bearer is configured, at least one of the first PDCP entity 521a or the second PDCP entity 521b may transmit data to the core network. In various embodiments, either the first PDCP entity 521a or the second PDCP entity 521b may not exist. BS 520a and BS 520b may perform direct communication with each other.

According to various embodiments, the first network and the second network are not limited as long as they are networks capable of dual connectivity. For example, each of the first network and the second network may correspond to LTE communication and NR communication, respectively. For example, the first network and the second network are all related to LTE communication, and the second network may be a network corresponding to a small-cell of a specific frequency. For example, the first network and the second network are both related to 5G, the first network corresponds to a frequency band less than 6 GHz (eg, below 6), and the second network is a frequency band of 6 GHz or higher (eg, over 6). You can also respond to.

The UE 510 according to various embodiments may transmit transmission data using the BSs 520a and 520b and at least one of a first network and a second network based on a split bearer. The UE 510 according to various embodiments sets the second network associated with the second BS 520b corresponding to the SCG as a primary path 531, and the first BS 520a corresponding to the MCG. The first network associated with the network may be set as a secondary path 532. For example, the UE 510 may set the second network associated with the SCG as the main route 531 based on information indicating the main route received from the MN. Information indicating the main path received from the MN may be included in an RRC signal (eg, RRC connection reconfiguration) and received. In another embodiment, there is no limitation on the manner in which the UE 510 configures the main path. The main path may be determined, for example, based on a policy of each communication service provider, and the UE 510 may check the main path by receiving information indicating the main path. The primary path may indicate a cell group ID and LCID of a primary RLC entity for uplink data transmission when a PDCP entity is associated with more than one RLC entity. The second PDCP entity 521b may be included in the base station 520a having a primary path. According to various embodiments, the first PDCP entity 521a may be included in the base station 520b having a secondary path.

In various embodiments, the UE 510 may check information on an uplink-data split threshold (ul-datasplitthreshold). The UE 510 may receive and confirm information on the uplink split threshold from the MN. The information on the uplink split threshold may be included in a UE-specific or UE-dedicated RRC signal (eg, RRC connection reconfiguration). According to various embodiments, there is no limitation on the manner in which the UE 510 checks information on the uplink split threshold.

Table 1 below is at least a part of an RRC connection reconfiguration message according to various embodiments.

As indicated by the underline above, in the RRC connection reconfiguration message, ul-datasplitthreshold may be defined as an uplink split threshold.

According to various embodiments, information on the uplink split threshold may also be determined based on, for example, a policy of each communication service provider. The UE 510 has two or more RLC entities (eg, a first RLC entity 542 and a second RLC entity 543) in which a transmitting PDCP entity (eg, a second PDCP entity 541) is And two or more related RLC entities (eg, the first RLC entity 542 and the second RLC entity 543) belong to different cell groups. In this case, the UE 510 may check whether the total amount of the PDCP data volume and the RLC data volume is greater than or equal to the uplink split threshold. When the total amount of the PDCP data volume and the RLC data volume is greater than or equal to the uplink split threshold, the transmitting PDCP entity of the UE 510 (for example, the second PDCP entity 541) converts the PDCP PDU into the main RLC entity ( Primary RLC entity) or secondary RLC entity (submit). When the total amount of the PDCP data volume and the RLC data volume is less than the uplink split threshold, the transmitting PDCP entity of the UE 510 (eg, the second PDCP entity 541) will provide the PDCP PDU only to the main RPC entity. I can. As described above, the UE 510 may transmit data through the main path 531 and the secondary path 532 when the size of the transmission target data is greater than or equal to the threshold. The UE 510 may transmit data through only the main path 531 when the size of the transmission target data is less than the threshold. In this case, data may not be transmitted/received through the secondary path 532 of the UE 510. An entity (or hardware associated with the secondary path 532) associated with the secondary path 532 may enter a connected mode DRX (CDRX) state based on no data being transmitted or received during a specified period, and various embodiments for this Will be described later.

5B is a diagram illustrating a path between a UE and a BS when a split bearer is configured in EN-DC according to various embodiments.

The UE 510 according to various embodiments may set a split bearer in EN-DC, and accordingly, the NR PDCP entity 541 may be associated with the LTE RLC entity 542 and the NR RLC entity 543 have. The LTE RLC entity 542 may be associated with the LTE MAC entity 544 and the NR RLC entity 543 may be associated with the NR MAC entity 545. The NR MAC entity 553b of the BS 550b may correspond to the NR MAC entity 545, and the LTE MAC entity 553a of the BS 550a may correspond to the LTE MAC entity 544. The NR PDCP entity 551a of the BS 550a may be associated with the LTE RLC entity 552a, and the NR PDCP entity 551b of the BS 550b may be associated with the NR RLC entity 552b. The LTE RLC entity 522a may be associated with the LTE MAC entity 553a, and the NR RLC entity 552b may be associated with the NR MAC entity 553b. The NR network may be set as the primary path 531 and the LTE network may be set as the secondary path 532. In EN-DC, in the case of the LTE BS 550a, it has been suggested in the standard that the NR PDCP entity 551a is set. In particular, for a split bearer, the LTE BS 550a may have to be configured as an NR PDCP entity 551a. The NR PDCP entity may be in the BS 550a of LTE, or may be in the NR BS 550b. In the case of a split bearer, at least one of the NR PDCP entity 551a of the LTE BS 550a or the NR PDCP entity 551b of the NR BS 550b may transmit data to the core network. Effectively, it may be advantageous to have the NR PDCP entity 551b set up in the primary path 531. However, it may also be possible for the NR PDCP entity 551a to be set in the LTE BS 550a, and for this reason, the NR PDCP entity 551a is indicated by a dotted line. In addition, LTE BS (550a) and NR BS (550b) can directly transmit and receive data with each other. Meanwhile, as described above, in addition to the EN-DC as shown in FIG. 5B, various embodiments of the present disclosure may be applied by various DCs.

6A is a flowchart illustrating a method of operating an electronic device, an LTE base station, and an NR base station according to various embodiments.

According to various embodiments, the electronic device 101 (for example, at least one processor (for example, the processor 120, the first communication processor 212), the second communication processor 214, or the integrated communication processor 260 At least one) may establish a connection with the LTE base station 340 in operation 601. The electronic device 101 establishes a connection with the LTE base station 340, for example, related to the LTE base station 340. The MME obtains the IMSI of the electronic device 101 (eg, UE), the electronic device 101 authenticates the LTE network, the MME authenticates the electronic device 101, NAS security setup, It may include at least one of location update, or EPS session establishment, and entities other than LET base station 340 (eg, eNodeB) (eg MME, S-GW, P-GW, HSS) , PCRF, SPR) will be easily understood by those skilled in the art that the connection can be formed by the operation of the. For example, the electronic device 101 is not only the LTE base station 340 but also the LTE base station 340 A connection may be formed by transmitting and receiving data with an entity of, and the formation of a connection may mean attach complete.

In operation 603, the electronic device 101 according to various embodiments may establish a connection with the NR base station 350. For example, the LTE base station 340 may transmit an RRC Connection Reconfiguration message including a config for SCG cell measurement (e.g., MO (measurement object) for SCG), and the electronic device 101 The result may be transmitted to the LTE base station 340. The LTE base station 340 may select the SCG, transmit an additional request (eg, SgNB Add Request) to the selected NR base station 350, and receive an Ack for this from the NR base station 350. have. The LTE base station 340 may transmit an RRC connection Reconfiguration message for additional SCG configuration to the electronic device 101. The electronic device 101 may perform SSB synchronization and perform RACH with the NR base station 350. Accordingly, SCG addition may be completed (SCG add complete).

According to various embodiments, in operation 605, the electronic device 101 may set an uplink path through the SCG (or SN) as the main path. For example, the electronic device 101 may set the uplink path through the SCG as the main path based on information in the RRC connection reconfiguration message. When the size of the data to be transmitted (eg, the total amount of the PDCP data volume and the RLC data volume) is smaller than the uplink split threshold, the electronic device 101 may transmit the transmission data through the main path.

According to various embodiments, in operation 607, the electronic device 101 may check whether the timer expires. The electronic device 101 may start a timer (eg, a DRX inactivity timer) after successfully decoding a physical downlink control channel (PDCCH) indicating uplink or downlink user data for the electronic device 101. For example, a timer may be started for a secondary path other than the UL main path of the electronic device 101. Parameters related to discontinuous reception (DRX) may be reflected in the MAC-Main config of the RRC connection reconfiguration message, but there is no limitation on a method in which the electronic device 101 obtains the parameters related to DRX. The expiration time of the timer may be expressed as, for example, the number of consecutive TTIs, and the electronic device 101 may monitor the PDCCH until the timer expires. If transmission data or reception data is expected as a result of monitoring the PDCCH, the timer may be restarted. If the timer does not expire (607-No), in operation 608, the electronic device 101 may receive data through the downlink path through the MCG or transmit data through the uplink path.

According to various embodiments, when the timer expires (608-Yes), in operation 609, the electronic device 101 may enter the CDRX state. Here, when the electronic device 101 enters the CDRX state, the node whose timer has expired in the electronic device 101 stops constant PDCCH monitoring and is performed at a specified period (e.g., a short DRX cycle or a long DRX cycle). This may mean performing PDCCH monitoring. In the CDRX state, the electronic device 101 may periodically monitor the PDCCH in the path corresponding to the MCG. In this case, in operation 610, the LTE base station 340 may also enter the CDRX state. The LTE base station 340 may enter the CDRX state by self-identifying that the timer has expired, for example. The LTE base station 340 may transmit data while the electronic device 101 monitors the PDCCH, and may wait for data transmission while the LTE modem of the electronic device 101 is in a sleep state.

According to various embodiments, even while the electronic device 101 transmits and receives data through a path through an SCG, if data is not transmitted or received through a path through an MCG, a CP corresponding to the MCG may enter the CDRX state. The electronic device 101 may control the CP corresponding to the SCG in an active state while the CP corresponding to the MCG is in the CDRX state. Alternatively, the electronic device 101 may control only the block corresponding to the MCG among the integrated CPs to the CDRX state and control the block corresponding to the SCG to the activated state. The block may represent independent hardware that enables the SoC to perform a CP operation, or may represent a logical block.

In FIG. 6A, it has been described that a path corresponding to NR is set as a main path and an entity (eg, CP) corresponding to LTE enters the CDRX state, but this is merely exemplary, and the electronic device 101 is A corresponding path may be set as a main path, and an entity (eg, CP) corresponding to the NR may be set to enter the CDRX state according to the expiration of the timer. In various embodiments of the present disclosure, operations performed based on an entity related to NR of the electronic device 101 and operations performed based on an entity related to LTE may be exchanged and performed.

6B is a timing diagram illustrating an operation in a CDRX state according to various embodiments.

According to various embodiments, at least one of the first communication processor 212, the second communication processor 214, or at least a portion of the unified communication processor 260 of FIG. 2A or 2B is a CDRX state based on the timer expiration. You can enter with In operation 611, the electronic device 101 may receive a DL grant and DL data on the PDCCH. The electronic device 101 may restart the timer. Before the timer expires, the electronic device 101 may check for UL Grant on the PDCCH in operation 613, and transmit UL data in operation 615, for example. The electronic device 101 may restart the timer 617 (eg, DRX inactivity timer). Before the timer expires, the electronic device 101 may monitor the PDCCH at all times, for example, for all subframes.

According to various embodiments, when the timer expires, the electronic device 101 may enter the CDRX state. In the CDRX state, the electronic device 101 may perform PDCCH monitoring in a short DRX cycle 621. For example, the electronic device 101 may not perform PDCCH monitoring for some subframes. The monitoring execution period may be performed during an on duration 623. During periods other than the on-period 623, an entity (eg, CP) entering the CDRX state of the electronic device 101 may be in the sleep state 627, and accordingly, power consumption may be saved. The electronic device 101 may start a DRX short cycle timer 619 while entering the CDRX state. When the DRX short-term cycle timer 619 expires, the electronic device 101 may monitor the PDCCH with a long DRX cycle 625. When the RRC inactivity timer 629 expires, the electronic device 101 may enter an RRC idle state and monitor the PDCCH with a paging DRX cycle 631. In various embodiments, when the electronic device 101 enters the CDRX state, the electronic device 101 may monitor the PDCCH in one single cycle (eg, a long DRX cycle).

Meanwhile, a base station (eg, an LTE base station) according to various embodiments may transmit data to the electronic device 101 during the on-period 623 of the electronic device 101. The electronic device 101 and the base station can synchronize the DRX cycle, and accordingly, the base station can also check whether the electronic device 101 is in the on-period 623 and the sleep state 627. Based on this, the electronic device (101) can be scheduled. If the base station acquires data and completes the modulation during the sleep state 627 before the on-period 623, until the on-period 623 arrives, data (e.g., among DL Grant or DL data) At least one) can be waited for transmission.

As described above, the electronic device 101 may monitor the PDCCH in at least one period, and the LTE base station 340 may be set to transmit data to the electronic device 101 during the monitoring period. In operation 705, the electronic device 101 may transmit transmission data to the NR base station 350 through, for example, a main path. The NR base station 350 may transmit transmission data to the core network 700 (eg, the core network 330 of FIG. 3A) in operation 707.

Can be delivered to the LTE base station 340. For example, the electronic device 101 may be configured to use an LTE communication network for the downlink. The transmission data may be data corresponding to the transmission data. As described above, the LTE base station 340 may wait for data transfer during the CDRX state waiting period (eg, the sleep state 627) in operation 711. The LTE base station 340 may include the electronic device 101. Data transfer may be waited until the monitoring period (eg, on-period 623) arrives. In operation 713, the LTE base station 340 may perform a CDRX waiting period (eg, a short DRX cycle 621 or DRX). The expiration of the long cycle 625) may be checked in operation 715. In operation 715, the LTE base station 340 may transmit received data to the electronic device 101. In operation 717, the electronic device 101 may According to a comparative example, the LTE base station 340 may wait for the transmission of received data in the CDRX state until the CDRX waiting period expires, and accordingly, the electronic device 101 receives it. The time required to process data may increase, for example, in the case of a ping transmitted from an electronic device or a web browsing screen request, the increase in time may be intensified.

7B is a flowchart illustrating operations of an electronic device, an LTE base station, an NR base station, and a core network according to various embodiments.

For example, the electronic device 101 may set a split bearer for an uplink. The electronic device 101 may set the NR-based path as the main path of the uplink and the LTE-based path as the secondary path of the uplink.
