中，eNB接收Msg3。因為即使多個正在競爭的ue傳送 Msg3，eNB也只會接收到一個Msg3，eNB藉由回應傳送 0990166-TW-D1 /9132-A43 367TW/final 12 201216757 該Msg3的UE以解決競爭。當UE接收到回應（例如一 =CH傳送或-包含UE身分的dl_sch傳送）時，证則 疋R A私序已經成功完成且上行鏈路時間已經校準完成。 RA程序可能會關聯到等待時間。舉例而言，UE可 月b而要等待RA回應或競爭解決或在一後移時間作扣“迀 tjme)等待。後移時間於下面描述。若ue因為傳送的前導 ^料並未被eNB所债測到或UE沒收到競爭解決而導致尺八 嘗^失敗’則UE必需重新開始RA前導資料階段。為了避 免競爭以及負載，在UE再次嘗試傳送RA前導資料前，舰 可告知UE需要等待一段時間。用以控制等待時間的參數

Each transmitter 222 receives and processes a respective symbol stream to provide one or more analog signals, and further processes (eg, amplifies, filters, and upconverts) analog signals' To provide a modulated signal suitable for transmission through the multiple input multiple output channel, the τ modulating signals of the transmitters 222a to 222t are respectively transmitted via the Ντ antennas 224a to 224t. The receiving system 250 transmits the modulated modulated signals via Nr The antennas 252a through 252r receive and provide signals received via each antenna 252 to receivers (RCVR) 254a through 254r. Each receiver 254 processes (e.g., amplifies, filters, and downconverts) the respective received signals, These processed signals are digitized to provide samples and further processed to provide a corresponding "received" symbol stream. Receive data processor 260 receives and processes NR received according to a particular receive processing technique NR received symbol streams of 254, which in turn provide τ "detected" symbol streams. Next, receive data processor 260 performs demodulation, sinking, and decoding each detected symbol stream. To restore the traffic data of the data string, the processing of the receiving data processor 26 is exactly the opposite of the processing performed by the transmitting MIMO processor 220 and the transport data processor 214 of the transmitting system 210. The processor 270 periodically Determining which precoding matrix to use (the following discussion), the processor 270 sets a reverse Hnk message. The reverse link message includes a matrix index 畑 咖 0 0990166-TW-D1/9132- A43367TW/fmal 8 201216757 part and a rank value part. The reverse link message contains a variety of messages related to the communication link and/or the received streaming stream. The reverse link message is then processed by the transport data processor 238, modulated by the modulator 28, processed by the transmitter 25 to 254r, and transmitted back to the transport system 21, where the data is processed. 238 also receives traffic data from a plurality of data streams of data source 236. In transmission system 210, modulation signals from receiving system 25A are received by antenna 224, processed by receiver 222, and demodulated by demodulator 240. Then, the receiving data processor 242 obtains the reverse link message transmitted by the receiving system 250. Next, the processor 23 determines which precoding matrix to use to determine the weight of the beamforming and processes the resulting message. According to an embodiment, FIG. 5 is a simplified schematic diagram of a communication device. The communication device 300 in the wireless communication system can be used to implement the user equipment 104' in the figure and the wireless communication system is preferably a wireless communication system using long term evolution technology or long term evolution advanced technology. The communication device 3A includes an input device 302, an output device 3〇4, a control circuit 306, a central processing unit 308, a memory unit 31, a program code 312, and a transceiver 314. The code 312 includes all layers of the application layer and control planes 〇8 and all layers of the user plane 110, except that the physical layer is not included. The control circuit 306 executes the code 312 stored in the memory 31 through the central processing unit 308, thereby controlling the operation of the communication device 3. The communication device 300 can receive signals input by the user through the input device 3〇2 (such as a keyboard or a small keyboard), and can also output images and sound through the output device 3〇4 (such as a screen or a zoom). The transceiver can be used to receive and transmit the wireless 0990166-TW-Dl/9132-A43367TW/fmal 0 201216757, transmit the received signal to the control circuit 306, and output the signal generated by the control circuit 306 in the state of wireless transmission. The long-term evolution technology (1^丁£) downlink (〇〇\¥1111111<:, 01^) transmission mechanism is based on Orthogonal Frequency Division Multiple Access (OFDMA), long-term evolution The technology (LTE) uplink (UL) transmission mechanism is based on Single-Carrier (SC) Discrete Fourier Transform (DFT) extended orthogonal frequency division multiple access (DFT-S-OFDMA) ) or single carrier frequency division multiplexing access. However, Long Term Evolution Advanced (LTE-A) is designed to meet the needs of higher bandwidths in UL and DL. In order to provide higher frequency bandwidth requirements, the Long Term Evolution Advanced Technology uses Carrier Aggregation (CA) technology to aggregate multiple component carriers. User equipment with carrier aggregation reception and/or transmission capabilities is capable of simultaneous reception and/or transmission over multiple component carriers. The carrier system can be defined by the bandwidth and the center frequency. The number of entity control channels used in the physical layer is related to the carrier aggregation operation. The Physical Downlink Control Channel (PDCCH) informs the user equipment about the resource allocation of the paging channel (PCH) and the downlink shared channel (dl-SCH) and the HARQ information related to the downlink shared channel. The PDCCH is likely to carry an uplink scheduling grant that is used to inform the user equipment about the resource allocation for the uplink transmission. The Physical Downlink Shared Channel (PDSCH) carries DL-SCH data. The Entity Control Format Indicator Channel (PCFICH) informs the user equipment that the number of OFDM symbols used in the PDCCH 'PCFICH is transmitted in each sub-frame. Entity Hybrid The Automatic Repeat Request Indicator Channel (PHICH) has a HARQ ACK/NACK signal corresponding to the uplink transmission 0990166-TW-D1 /9132-A43 367TW/final ]〇 201216757. The Physical Uplink Control Channel (PUCCH) carries uplink control information such as HARQ ACK/NACK signals corresponding to downlink transmissions, scheduling requests, and Channel Quality Indicators (CQI) 〇 Entity Uplink Shared Channel (pusCH) With uplink shared channel (UL-SCH) data. In the long-term evolution advanced technology, a primary cell (PCell) is a serving cell operating in a primary frequency or a cell designated as a primary cell during a handover process, wherein the primary frequency user device can perform an initial link establishment procedure or link The frequency of rebuilding the program. The user equipment also utilizes the primary cells to generate parameters for use as security functions and as parameters for upper system information such as NAS action information. The secondary cell (SCell) includes the serving cell at the secondary frequency 'this secondary frequency is the frequency that can be configured for the user equipment after the RRC connection is established' to provide additional radio resources for carrier aggregation. When the SCell is added to the configuration of the user equipment, system information related to the operation of the SCell is provided to the user equipment using dedicated signals. Basically, the PCell includes an uplink component carrier (c〇 and the downlink CC; and the scell configured to the user equipment may include a downlink CC or an uplink in addition to a downlink CC) CC. In order for the transmission signals from different UEs to be orthogonal, the uplink transmission signal in LTE must arrive at the receiving end of the eNB at the frame time of the eNB. In LTE-A, 'for uplink time alignment (alignment) The PCell and SCell configured for the UE may require different Timing Advance values. When the time has not been calibrated or there is no data exchange for a period of time, and thus the eNB does not maintain time calibration, then a random access must be utilized ( RA) program to obtain time calibration. Therefore, the RA program uses 0990166-TW-D1 /9132-A43367TW/final η 201216757 for initial access from an idle state (RRC-IDLE); for wireless connection failure; In the handoff process; used for DL or UL data arrival in the RRC_CONNECTED state when UL is not synchronized due to power saving operation; used for UL data arrival without PcapCH available With scheduling requests, the RA program has two forms, a competitive RA program and a non-competitive RA program. The competitive RA program can be applied to the above four cases, but the non-competitive RA program can only be applied to the change. Hand program and DL data arrival. Details about the competitive and non-competitive RA procedures are documented in 3GPP TS 36.321 V9.3.0 and 3GPP TS 36.321 V10.2.0. In competitive RA procedures, uplink time alignment It is established by a four-phase procedure, including ra preamble, RA response, message 3 (Msg3) and contention resolution. In the stage of RA preamble data The UE randomly selects the RA preamble data sequence from the available sequence groups in the cell, and transmits the RA preamble data sequence in a random access channel (RACH). In the RA response phase, the eNB detects the preamble data. Transmit, predict the time of UE uplink transmission, and report the RA response to the UE to provide the UE with the correct timing advance value for the next transmission, and a first promise for uplink In the phase of MSg3, because the randomly selected RA preamble data is not used to judge the identity of the UE, the UE uses the promise provided by the RA response to provide the UE identity to the eNB and the first scheduled uplink link transmission. . In the contention resolution phase, the eNB receives Msg3. Because even if multiple competing ues transmit Msg3, the eNB will only receive one Msg3, and the eNB will respond to the UE by responding by transmitting 0990166-TW-D1 /9132-A43 367TW/final 12 201216757. When the UE receives a response (eg, a =CH transmission or a dl_sch transmission containing the UE identity), the certificate 疋R A private sequence has been successfully completed and the uplink time has been calibrated. The RA program may be associated with latency. For example, the UE may wait for the RA response or contention resolution or wait for a "后tjme" waiting time at the back time. The back-shift time is described below. If the ue is not transmitted by the eNB The UE may restart the RA preamble data phase if the debt is detected or the UE does not receive the contention resolution. In order to avoid competition and load, the ship may inform the UE that it needs to wait for a period of time before the UE attempts to transmit the RA preamble again. The parameter used to control the waiting time is the backward parameter, which is provided by the eNB through the RA response. Thus, before the UE attempts to transmit the RA preamble again, the eNB may force the UE to wait for a period of time. 1 The maximum length of the handover time is borrowed by the eNB. The UE is informed by the backward shift parameter, and the foregoing method is performed by the eNB by transmitting an indicator to the UE. The backward shift parameter is represented by an actual waiting time in milliseconds and the waiting time is called a back shifting time. After the RA fails, the UE can try again.

The range of back-shift time according to 3GPP TS 36.321 V9.3.0 and 3GPP TS 36·321 V10.2.0 is between 〇 and 96 〇 milliseconds. In the non-competitive RA procedure, uplink time alignment is established in two phases, including the RA preamble phase and the RA response phase. In the RA preamble data phase, the UE uses a pre-specified RA before

In the rA response, the eNB detects the preamble data transmission, predicts the UE's uplink transmission time, and provides the UE 'eNB with the correct timing advance value for the next transmission in the RA response report, and a first promise. Take the 0990166-TW-D1/9132-A43367TW/fmal iq 201216757 line uplink transmission. When the UE receives the RA response, the UE determines that the RA procedure has been successfully completed and the uplink time has been calibrated. When multiple timing advances (TAs) are used, the SCell may need to execute the RA procedure to obtain its corresponding TA value' and there will be multiple serving cells that can perform the RA procedure. For example, 'each serving cell uses the ra program to obtain a TA value corresponding to a TA group, and the serving cells in the TA group share the same TA. Therefore, at least the PDCCiI command can cause the RA program on sCeU. In a possible embodiment of initiating the RA procedure on the SCell, the eNB first configures an SCeU that requires a τα value different from the PCell, then the eNB initiates the SCeU, and then the eNB transmits a PDCCH order to trigger the RA procedure on the SCell, The IJL time of the SCell can be calibrated. The SCell's stop timer is used to implicitly stop (impUcitly deactivate) - the configured SCell. The operation of the stop timer is described in R2-105220 (Introduction to Carrier Aggregation) and 3GPP TS 36.321, V10.2.0 (E-UTRA; MAC Protocol Specification). When §cell starts, SCell's stop timer will start. According to the document R2_1〇4626, the stop timer has a limited range between 10 and 5 〇 milliseconds, or according to the document 3GPP TS 36.331 V10.2.0 (E-UTRA; RRC protocol specification), the stop timer has a limited The range is between 2 〇 and 128 〇 milliseconds. Because the ra program executing on the SCell may be associated with a wait time (eg, waiting for an RA response, contention resolution, or when in the back-shift time 〇 _96 〇 milliseconds) 'When the random access procedure is performed on the SCell, the UE has The SCeU may be implicitly stopped because the stop timer expires. However, this is an unexpected behavior because the RA program is interrupted, _ needs to be started again, and the RA spears need to be sent again. Therefore, additional signals are required and more delay is caused by the UL time calibration of the 0990166-T W-D1 /9132-A43 367TW/final 201216757 SCell. In order to avoid implicitly stopping the SCeU' eNB, it may be necessary to continuously transmit a downlink assignment or an uplink grant to the SCell to restart the stop timer, which would result in wasted signal load and resources. In accordance with an embodiment of the present invention, the SCell should not be implicitly stopped when the RA program on 8 (>11 has been initiated or is in progress. Figure 6 illustrates a method 400 of stopping the SCell in accordance with an embodiment of the present invention. The RA procedure for the SCell is initiated in step 402. In step 404, when the RA for the scell has been initiated or the RA for the SCeU is in progress, the SCell is not implicitly stopped. Therefore, the SCdl that is performing the RA procedure can be prevented. In accordance with another embodiment, the step of not implicitly stopping the SCell in step 404 includes the UE restarting or starting the SCell's stop timer when the RA program is started on the SCell. Restarting or starting the SCeU The time of stopping the timer may be when the PDCCH command of the SCell is received. When the preamble data is transmitted by using the physical RA channel (prACh) of the SCell or when the command entity layer transmits the preamble data by using the PRACH of the SCell, the The stop timer of the SCell is started. All of the above steps can be partially performed completely. According to another embodiment, the step of not implicitly stopping SCdi in step 404 includes when the RA program is started on the SCell When the time is up, the UE stops or suspends the SCell's stop timer. In the following brothers, the SCell may not be restarted or started. Stop timer: (1, +) The RA program on the SCell is in progress. (2) receiving an assignment to the random access wireless network temporary identifier (RA-RNTI) on the SCell, with the downlink key 0990166-TW-Dl/9132-A43367TW/final 15 201216757 control Channel (PDCCH); (3) receiving a PDCCH assigned to a Cell Radio Network Temporary Identifier (C-RNTI) on the SCell. When the RA procedure is successfully completed, the SCell stop timer can be restarted and started. Or continue. During the RA private sequence execution on the SCell, the SCell's stop timer can be stopped or paused when the UE starts performing the backward shift. However, when the back shift stops, the UE can restart or continue the SCell stop timing. When the contention res〇lutiori timer of the program on the SCeu is started, the stop timer of the SCell can be stopped or suspended. In addition, when the contention resolution timer is stopped or expired, the UE can be restarted. Or continue SCeli Stopping the timer. All of the above steps may be performed partially or completely. According to another embodiment, the step of not implicitly stopping scei in step 404 includes a UE setting the stop timer value of the SCell to infinity, or stopping SCell's implicit stop mechanism. When the RA procedure is successfully completed: (1) the value of the SCell stop timer can be set to the value configured by the eNB; or (2) the implicit stop mechanism of the SCell can be restored, or (3) the stop timing of the SCell can be started. Or reboot. All of the above steps can be performed partially or completely. According to another embodiment, the step of not implicitly stopping the SCell in step 404 includes not suspending the SCell stop timer if the time alignment timer corresponding to the SCell is not operational. When the first Ra program is performed on the SCell after the SCell is successfully started, the SCell stop timer can be started. All of the above steps can be performed partially or completely. According to another embodiment, the step of not implicitly stopping the SCell in step 404 includes if the RA procedure on the SCell is in progress or corresponds to the OR sequence of 0990166-TW-D1 /9132-A43 367TW/final 16 201216757 SCell Ongoing, while the stop timer for SCeu expires 'UE' does not stop SCeU. The RA procedure on the SCell means that the RA preamble of the RA procedure is transmitted on the SCell. In another embodiment, the RA procedure corresponding to the SCell means that the RA preamble of the RA procedure is transmitted on another SCell, where the SCell and the other SCell belong to the same group. When the stop timer expires, the SCell's stop timer can be started or restarted. All HARQ buffers associated with SCe11 may not be emptied because of the stop time. The stop timer can be sCellDeactivationTimer. The RA program can be a competitive RA program or a non-obtrusive RA program. If the RA program on the SCell or the RA program corresponding to the SCell is not in progress, when the stop timer expires, the stop timer may not be started or restarted. If the RA program on the SCell or the RA program corresponding to the SCell is not in progress, the #STOP timer expires, and the HARQ buffer associated with the SCell can be cleared. When the stop timer expires, the HARQ buffer associated with SCe11 can be emptied (according to 3Gpp TS 36.213 V10.2.0 "E_UTRA; physical layer process, the time of transmission time (TTI) defined in the time is no later than n +8 sub-frames, where the stop timer expires in sub-frame n.) If the RA program on the SCell or the RA program corresponding to SCdl is not in progress, the SCell may be stopped when the stop timer expires (according to 3GPP TS 36.213 V10.2.0 "E-UTRA; physical layer procedure" The time of transmission time (ΤΉ) is not later than n+8; = box, where the stop timer expires in sub-frame η.

When the first SCell is used to perform the RA procedure, the eNB may not enable or never enable the implicit stop function of the first SCell. However, after the RA procedure is completed, the eNB may enable the implicit stop function of the first SCell. In addition, the eNB may enable an implicit stop function of the second SCell that does not need to execute the RA procedure. The stop function of the first SCell is not enabled, that is, the sCellDeactivationTimer value for the first SCell is not configured (eg, the sCellDeactivationTimer information element is not provided (IE) )), or set about the first
