Description

201108781 VI. Description of the Invention: [Technical Field] The present invention relates to a method for a wireless communication system and a communication device thereof, and more particularly to a method for processing a wireless link failure in a wireless communication system and Communication device. [Prior Art]

The Long Term Evolution (LTE) wireless communication system is an advanced high-speed wireless communication system built on the third generation mobile communication system (such as the global mobile telecommunication system), which only needs to support PacketSwitched transmission, and The Radio Link Control 'RLC layer and the Medium Access Contro MAC layer can be integrated into the same communication network unit. In a long-term evolution system, a user terminal and a Universal Terrestrial Radio Access Network (UTRAN) may be due to signal impairments, unfavorable signal propagation environments, or system malfunctions in the wireless environment. And the wireless link failure (radiolink failure, RLF). Therefore, a timer for detecting a failure of the wireless link is defined in the UE, and the UE is assigned to a component carrier or to a cell. For example, when the UE detects a wireless problem on the cell to which the component is assigned or connected, it starts a timer that is used to prepare for the failure of the component carrier or the cell's wireless link. $This leaf timer expires when the user _ identifies this component touch or the scale chain of this cell is defeated. This timer can be used to determine if a component carrier or cellular wireless bond has failed in the event of a wireless problem. 201108781 To further develop high-speed wireless communication systems, such as increasing the peak transmission rate of transmission data, the 3rd Generation Partnership Project (3rd Generation Partnership PiOj(10), 3GPP) developed an advanced long-term evolution (LTE Advanced) system based on the LTE system. The main objectives of the LTE-Advanced system include fast switching power state, cell marginal performance improvement, bandwidth extension, and coordinated multipoint transmission/reception (c〇〇rdinated).

MultipointTransmission/Reception ’ COMP), and technologies such as Multi-Input Multi-Output ’ 。. To achieve the goal of bandwidth extension, 3GPP proposes a carrier aggregation concept in the LTE-Advanced system. The UE allows two or more component carriers to be used to enjoy a larger transmission bandwidth, for example, a maximum bandwidth of 100 MHz to support spectral efficiency. According to the compatibility of carrier integration, multiple component carriers can be assembled into a continuous large bandwidth. Therefore, the UE can establish a connection corresponding to a plurality of components, and can perform a transmission/reception function every time the component is loaded. In addition, 'coordinated multi-point transmission/reception can be regarded as one of the functions used in LTE-Advanced system to improve high-speed transmission range, cell marginal transmission, and system efficiency. Among them, coordinated multi-point transmission/reception represents dynamics between geographical points. Coordination means that when the client is located in a cell marginal area, the client can receive signals from multiple cells and can transmit functions to multiple cells. Each client of the Long Term Evolution system is only allowed to connect to one component of a component carrier. When the UE detects a wireless problem on the component carrier or cell, the UE initiates a timer to perform wireless link failure detection for the component carrier or cell. However, according to the LTE-Advanced system architecture, the client operates in carrier integration 201108781 or/and coordinates the township/receiver, and can link multiple cells in the _ or different component carriers. In the LTE_Advanced system, it is not clear how the UE that connects multiple component carriers or multiple cells should use the wireless key failure detection function. In addition, in the wireless link failure detection function, the usage of the timer for detecting the failure of the wireless link is not clearly defined. For the use of multi-component carriers, the improper start of the timer may cause the connection of the client to be abnormal. In addition, when the component carrier of the UE fails to be wirelessly linked, the situation should be notified to the network # terminal to assist the UE in handling the wireless key failure. Therefore, how to transmit information about wireless link failures of multiple component carriers is also an important issue.

For example, the UE communicates with cell C1 via wireless link L1 and with cell C2 via wireless link L2~L4, and so on. Since each wireless link pair in the wireless link 1/1~1^11 should be on the -component carrier, the cell, therefore, at least the component carrier or cell ci~~ allocated by the UE can be defined in this specification. For the user's target (ridge t〇f interest). In other words, the user considers the connected cell or the component carrier assigned to it as the target to be connected. Referring to FIG. 2, FIG. 2 is a schematic diagram of a communication device 2 according to an embodiment of the present invention. The wireless communication device 20 can be the client in the i-th figure, and includes a processing unit = a storage unit 210 and a communication interface unit 220.

The above plurality of targets may be component carriers or cells. Or flexible tube = Inventive solution provides a method for processing wireless key connections for a plurality of component carriers/cells, which can be used to reduce the number of signaling and maintain link performance. 9 201108781 The wireless link failure detection function. In order to reduce the number of signaling, the first embodiment of the present invention provides a procedure for processing a wireless key failure _ with respect to a component carrier in a - terminal in a wireless communication system. In this case, the carrier's standard time carrier is taken as an example, but it is not a limitation of this reality. The wire 30 can be compiled into the code 2M and includes the following steps: Step 300: Start. Step 302: Perform no-problem detection on a plurality of component carriers. Step 304: When a wireless problem is detected on all component carriers, a timer for detecting a failure of the wireless link of the plurality of component carriers is initiated. Step 306: End. According to the process 3G, when the __ wireless_, the user initiates-shared timer ’ to determine whether the component carrier has a wireless key failure

(-e, RL heart In other words, the UE will start the timer when all component carriers have wireless problems. For example, the wireless chain (4) measurement operation. The UE first performs wireless problems on multiple component carriers. _, and when the user side - real = skin λ long all the 詈 詈 詈 _ _ _ _ _ real mm multiplex contiguous non-synchronous (coffee _ plus out-of-synchronization) indication to the user her f (four) am % The radio resource control layer. When the radio resource control layer receives the number of consecutive non-synchronizations, the user that detects the failure of the radio link of all component carriers starts to detect 10 201108781 when all component carriers have wireless When the problem starts, the timer can be reduced. The number of signaling is controlled by the 2-line resource control lion. For the example, please refer to the figure. The user end has a wireless link u~Lm corresponding to a plurality of component carriers. When the physical layer detects the wireless problem on the wireless key LWLm], the physical layer does not; several consecutive asynchronous indications to the RRC layer, and when the physical layer further detects on the wireless link Lm _ no problem 'The physical layer will produce even Phase:: to wireless: recording the control layer to start the timer for wireless link failure detection. In the embodiment of the present invention, the number of signaling of the continuous asynchronous indication can be reduced. The physical layer needs to generate a continuous non-synchronous value of a specific value, which may be one of the N310 parameter values in the long term evolution system. Further, when the UE initiates a timer for detecting a plurality of component carriers. After the user end before the timer expires, the line gate = defeat when the user side and the component carrier are synchronized. j asks for the test. +8 A user ^ the physical layer determines the knife carrier I line _ Secret recovery, and generate a continuous (consecutive in-synchronization) ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ When the RRC layer receives a plurality of consecutive synchronization refers to the end of the system, the timer to avoid wireless links _ 停止 停止 。 。 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ When signaling, the user _ thinks that this component takes a step = _ Before the expiration of the server, if the user detects the signaling on the wireless link u, the wireless __ her secret ^ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ It can be transmitted to the user through the network---------------------------------------- The heart is a secondary cell, and the set value of the timer can be obtained through the system of cell α. However, if the user terminal is not synchronized with any component carrier, that is, the wireless problem is not fixed, then when the time is closed, The user touches the age of Laibo and the wireless key fails. If the access layer (ACcess Stratum, AS) security function is enabled, the UE may perform a radio resource control link re-establishment procedure to reconstruct at least a plurality of component carriers - a wireless link. It is worth noting that the boot state of the access layer security function means that the user has a data radio be. In addition, if the wireless connection re-establishment procedure is successful, the UE maintains the radio resource control connection mode and can use the re-established wireless link radio resources. On the other hand, if the benefit line control link rebuilds (10) and can't repair the secret chain tree, the client _ changes to;; wireless resources (four) job mode τ, concurrent wireless. Please refer to FIG. 4'. FIG. 4 is a schematic view of the communication device 4 of the first embodiment of the present invention. The communication device 40 is used to implement the process, and includes a detecting unit, a unit 402', and a wireless link establishing unit 4〇4. The detecting unit is configured to perform a wireless problem _ on the component carriers (3) to (5) to which the communication device 4G is allocated, and to generate an indication signal S when the wireless carriers are both on the component carriers CA1 to CAm. The management private 4G2 is used to start the timer of the wireless link failure of the component CA1~CAm according to the indication signal s. Preferably, the indication signal s comprises a plurality of consecutive asynchronous indications. In addition, when it causes the detected wireless problem to be repaired, the tilting unit further generates a number of 12 201108781 consecutive synchronization indications, and the management unit stops the timing according to the plurality of consecutive synchronization indications. Irrelevant questions - straight to the secret, when the timer expires, the management unit - judges the wireless bonding of the component carriers CA1 ~ CAm failed, and generates - (four) 峨 cs to the wireless link establishment unit · 1 access layer protection ^ When the power can be started, the wireless link establishment is performed by (4) according to the control signal cs, and the wireless resource control link reconstruction procedure is performed. For detailed operations of the communication device 40, reference may be made to the above description, and details are not described herein again. In terms of maintaining the connection performance of the client, the second embodiment of the present invention provides a process 50 for use in a UE in a wireless communication system for handling a wireless link failure with respect to a component carrier. In this embodiment, the component carrier of the user terminal is not limited to this embodiment. The process 5 can be compiled into a code called, and includes the following steps: Step 500: Start. Step 502: Perform wireless problem detection on a plurality of component carriers. φ Step 5〇4 • When a wireless problem is detected on the component carrier of a plurality of component carriers, a timer for detecting the failure of the wireless link of the component carrier is initiated. Step 506: End.

When the Shankang Air Spear King 50' is prepared on one of the component carriers and the wireless problem is detected, the user initiates an independent timer to determine whether the wireless carrier is lost on the component carrier. The pair of component carriers having no problem is started, respectively, and according to FIG. 1 , an example is illustrated. When there is a wireless problem corresponding to the component of the wireless link u, the user initiates a timer, and when the wireless problem of the corresponding wireless seam is U 13 201108781, the user initiates another timer. And (4) the operation of the gate _, the user first to wirelessly detect the Wei surface carrier. When one of the components carries: the physical layer will generate a plurality of consecutive asynchronous indications to use: = ==: When the layer receives these consecutive asynchronous indications, when the UE initiates one of the radio link failures for detecting the component carrier, in the process 50, the 'as-is-component carrier has a wireless problem. A plurality of consecutive unsynchronized indications to the benefit line resource control wave reference FIG. 1 'the user end has a plurality of component-loaded asynchronous indications to the radio resource control layer to start for the wireless key Preferably, the physical layer generates - the connection of a specific value - the value can be the aforementioned parameter value of Ν 310.

When the usage carrier regains synchronization, the physical layer of the user side judges the wireless-complex of the component carrier and generates the Wei-line resource control layer. (4) When the user-free terminal of the main user of the day stops the multiple consecutive synchronization indications, the A-stop is used to stop the Is to avoid the wireless link failure. Preferably, the f-body layer generates a continuous value of a specific value: Then the parameter value. As mentioned above, the timer can be the timer = and the reference material of the phase operation of the tip 0, and then re-reported. 201108781 However, if the client does not synchronize with this component carrier, this is the case. 'When the timing of the 11th period expires, the user determines that the age carrier has generated ',., and the line link, and the reader knows that there is a component to the network. If the user and this component are loaded:; Loss: Machine access procedure The construction of this component touches the wireless link, the machine access program is successfully completed, the heart can be money, and if the random access procedure fails and the wireless link cannot be repaired, _= holds the wireless Wei (four) Under, the material can be made ^ = when the user has all the points When the carrier is in the wireless ^^2, when the user starts, the user initiates the wireless Wei control link re-establishment program to rebuild the mountain. If the scale _ control money is successfully transferred: Waiting for the wireless resource control connection mode, The rebuilt wireless chain source can be used. Conversely, if the wireless dragon and (4) link re-establishment and ...= key f, the user enters the radio resource control idle mode, and the value pays attention to the fact that the shed is over 50.

If rebuilt Program New Zealand/New Zealand wireless, user terminal ^ ^ control link: under the formula, silk Newcompe no _3 = ^ _ source control is referred to Figure 6, Figure 6 is an embodiment of the present invention - Picture. The communication device 6 is used to implement the process, and includes a unit called M1 to Mm, and a wireless link establishing unit 604. Detection unit D1~

Dm corresponds to the management units M1 to Mm, respectively, and is used for wireless problem detection on the tool carriers CB1 to CBm to which the communication device 6 is assigned. When a wireless problem is detected on the component carriers cbi to CBm, the detecting units D1 to Dm respectively generate the indication signal S1~

Mm corresponds to the component carriers CB1 to CBm, respectively, and the wireless link failure of the wire-side component carrier CB1 to CBm fails, and can be based on the indication signal

Sm 'starts separately - timer. Preferably, each of the indication signals includes a plurality of consecutive asynchronous indications. An example of the operation between the communication unit 6 _ units D1 to Dm, the management unit 夭 m and the wireless link establishing unit 6 〇 4 will be described in detail. It is assumed that the detection unit D1 detects a wireless problem side unit D1 on the component carrier CB1 and generates a finger _ := two units M1. The management unit M1 starts to detect the wireless of the component button CB1 according to the indication signal S1. The link failed - the timer. In addition, when the wireless problem detected on the component carrier CB1 is repaired, the timer is stopped. On the other hand, when 4 = Γ multiple timers expire, the management unit is unrepaired and fails, and generates a control signal (3) to detect the wireless link signal (3), if there is an access layer to establish a unit ,. According to the control of the wave (3) of the wireless chain, take the program to reconstruct the component load ~ D2 ~ Dm & management unit M2 ~ 201108781

The function of Mm is the same as that of the above-described detection unit D1 and management unit M1. For detailed operations of the communication device 60, reference may be made to the above description, and details are not described herein again. Considering the flexibility to increase the function of managing the wireless link failure, the third embodiment of the present invention provides a flow 7G, which is used in the wireless communication secret - in the user terminal, to process the wireless link nucleus about the component Hey. The component of the client is taken as an example of a component carrier, but is not limited to this embodiment. The process 7 can be compiled into the code 214 and includes the following steps: Step 700: Start. Step 702: Perform wireless problem detection on a plurality of component carriers. Step 704: When a - wireless problem is detected on one of the plurality of component carriers, the first timer for detecting the failure of the wireless link of the first component carrier is initiated. Step view: When a wireless problem is detected on a component carrier other than the first component carrier, a second timer for detecting a wireless key failure of the component carrier other than the first component carrier is initiated. Step 708: End. «Process 7G, when the first component carrier and the remaining component carriers have wireless problems, the first-a ten-timer and the second timer are respectively started to be used for the debt measurement of the first component carrier and the rest of the components. Wireless link. In other words, when the first component carrier detects an unrelated question, the user terminal _ determines whether the first component carrier has a wireless link failure first timer, and when it is detected on the remaining component carriers ... when the line problem occurs, the client will start a second timer for determining whether the remaining component carriers have failed the wireless key. 17 201108781 About the wireless link detection of the thumb #, wireless problem detection. When the object layer of the user side is in the problem of === a plurality of component carriers, a first-quantity continuous _ _ _ to the wireless layer is generated. Similarly, when the physical layer is in the remaining part, the radio resource control of the mobile terminal controls the continuous non-synchronization indication to the radio resource control layer. Wherein, the first quantity and the second quantity are the first timer of the wireless link failure of the receiving wave of the continuous-to-the-line resource control layer of the first to the first number of the radio resource control layer; When the first component is loaded with the asynchronous indication, the UE initiates a second timer for the second: 2-wire link failure. Preferably, the first component carrier is a two-f carrier, and the remaining component carriers are secondary component carriers. It seems to be the main knife 1 leaf = the terminal is open __ The first component carrier's wireless key failure is detected by the user and the first - continuous wireless problem detection.

When the wireless paste layer receives the first === ( 'user stop timer, the simple - the wireless key of the first component is lost. Reason, before the second timer expires 'if the user and the rest - the remaining component load The user determines that the wireless problem of the remaining component carriers is repaired. Therefore, the user layer transmits a fourth consecutive number of consecutive synchronization indications to the radio resource control layer. When the flute body source control layer receives the fourth number of consecutive synchronization indications. The UE will stop: the first timer to avoid the wireless link failure of the remaining component carriers. The third and fourth quantities mentioned above are set by the RRC layer. 18 201108781 Thin (four) pull right component The wireless problem of the carrier has not been fixed, when the first timing. The user determines that the wireless transmission of the first component carrier has failed. In this case, when the security layer security function is activated, the user will start the wireless resource.

It is worth entering After the source _ _, turn - the 嶋 19 19 201108781 / / will enter the wireless resource control idle mode. If the first component contains the sharp material no matter the knot, and the surface level of the county has been New pure line Wei control continued construction procedures, (four) · miscellaneous - = two knots. If the RRC connection re-establishment procedure successfully completes I, the line is difficult to connect in the mode, and the rebuilt wireless link can be used without the 'right radio resource control link re-establishment procedure fails and the line is chained' The UE enters the radio resource control room to release the radio resource of the component carrier. ^ Referring to FIG. 8 'Fig. 8 is the invention - the embodiment - the voice recording H of the POS 8 is used to implement the stream (4), and includes There are - _ unit café, a second = Τ 8 〇 2 Α, a second management unit 8 〇 2 Β ' and a wireless link to establish a single class.
