Wireless communication device, wireless access network, and management of multi-component carriers Method

The present invention relates to Carrier Aggregation (CA) technology, and particularly relates to a method for managing activation and deactivation of a Component Carrier (CC), and a wireless communication device and a wireless device. Access the network.

In order to cope with the demand for high transmission rate, the wireless bandwidth required in the wireless communication market is increasing day by day. For this reason, a technology called carrier aggregation has been developed, which can be integrated by integrating component carriers. Radio resources effectively provide higher bandwidth to the user, especially in the case where it is difficult to achieve continuous and wide bandwidth, carrier aggregation technology can achieve the highest efficiency. In simple terms, carrier aggregation technology refers to the integration of two or more frequency bands to provide a higher transmission/reception bandwidth. In general, each frequency band to be integrated can be referred to as a component carrier, that is, Is one of the components of the integrated bandwidth.

Specifically, each component carrier needs to be set and started before it can be used for data transmission/reception. Taking Long Term Evolution (LTE) technology as an example, a long-term evolution system can transmit a radio resource control (Radio). The Resource Control (RRC) information is used to set the component carrier used by the UE, and then the component is activated by dedicated signaling (for example, Medium Access Control (MAC) Control Element (CE)). Carrier. After that if the user The bandwidth required by the terminal is reduced, and the Long Term Evolution system can transmit a control element of another media access control to the UE to deactivate one of the component carriers. Alternatively, a deactivation timer (or may be referred to as a de-timer) may be used on the system side and/or the user end to time the corresponding component carrier to be continuously in a predetermined time interval of the startup state, to be stopped. When the timer expires, the system component and/or the user end can disable the corresponding component carrier. Since the user does not need to monitor the physical downlink shared channel (PDSCH) and the physical downlink control channel (PDCCH) on the deactivated component carrier, the user can effectively save the user's cost. electric power.

The present invention proposes to use a non-contention based and contention based random access procedure to initiate component carriers. 1 is a schematic diagram of a wireless communication system according to an embodiment of the invention. In the wireless communication system 100, the wireless communication device 110 wirelessly connects to the wireless access network 120 via an air interface to obtain wireless service. The wireless access network 120 includes at least one access node 121 and a control node 122. Generally, the access node 121 can be a wireless station, a base station, or an access station, or can be a broadband coded multiple memory. A base station of a (Wideband Code Division Multiple Access, WCDMA) network, or an evolved base station of a long-term evolution network, and Controlled by control node 122 to provide wireless transmission and reception of wireless access network 120. The wireless access network 120 can be further connected to a core network 130 for interfacing to an external network in the Circuit Switched (CS) domain (eg, Public Switched Telephone Network (PSTN)). IP network in the field of Packet Switched (PS) (for example: Internet). The combination of wireless access network 120 and core network 130 may generally be referred to as a so-called service network. The wireless communication device 110 includes a wireless module 111 for performing wireless transmission and reception functions. Further, the wireless module 111 can include a baseband unit (not shown) and a radio frequency (RF). A module (not shown), the baseband unit may include a plurality of hardware devices to perform baseband signal processing, including analog to digital conversion (ADC)/digital to analog conversion (DAC), Gain adjustment, modulation and demodulation, and encoding/decoding. The RF module can receive the RF wireless signal, convert the RF wireless signal into a baseband signal for further processing by the baseband module, or receive the baseband signal from the baseband signal module, and convert the baseband signal into a radio frequency wireless Signal for transmission. The RF module may also include a plurality of hardware devices to perform the above RF conversion. For example, the RF module may include a mixer to multiply the baseband signal by one of the RF carriers of the wireless communication system. Where the radio frequency can be 900 MHz, 1900 MHz, or 2100 MHz used by the wideband code division multiple access system, or 900 MHz, 2100 MHz, or 2.6 GHz used by the Long Term Evolution system, or other wireless access The technical standards depend on it. In addition, the wireless communication device 110 also includes The controller module 112 is configured to control the wireless module 111 and other functional modules (for example, a display unit for providing a human-machine interface and/or a keypad, and a code for storing an application and a communication protocol) The operational status of the storage unit, etc.). In an embodiment, the wireless access network 120 can be an Evolved Universal Terrestrial Radio Access Network (EUTRAN), and the wireless communication device 110 can be a user. The User Equipment (UE) follows the version 9 specification standards TS 36.331 and 36.321, the 10th edition specification TS 36.300, and/or other specifications of the Long Term Evolution Technology developed by the 3rd Generation Partnership Project.

Specifically, the controller module 112 controls the wireless module 111 to perform a non-competitive and competitive random access procedure with the wireless access network 120 to initiate a component carrier that has been set but not activated. 2 is an information sequence diagram of a non-contention random access procedure according to an embodiment of the invention. In this embodiment, the wireless access network 120 is an evolved universal terrestrial wireless access network, and the wireless communication device 110 is a user device. First, for the wireless communication device 110, there is already a set first component carrier (referred to as CC#1 in the text) and a second component carrier (referred to as CC#2 in the text), wherein CC#1 is set as the main component. The carrier (also referred to as PCC in the figure) and CC#2 are set as the secondary component carrier (also referred to as SCC in the figure). The wireless access network 120 can transmit a radio resource control information (eg, RRC Connection Reconfiguration information) to the wireless communication device 110 to perform the settings of CC#1 and CC#2 described above. It should be noted that CC#1 is the main point. The carrier is measured, so CC#1 is already in the startup state, and CC#2 is in the non-starting state. In order to activate CC#2, the wireless access network 120 first transmits a preamble configuration information to the wireless communication device 110 (step S210). Specifically, the foregoing configuration information includes a configuration context and a component carrier indicator. (For example, Carrier Indicator Field (CIF)), where the component carrier indicator is used to indicate the component carrier to be activated (ie CC#2). When receiving the foregoing configuration information, the controller module 112 transmits a Random Access Preamble (RAP) information to the wireless access network 120 on the CC#2 via the wireless module 111 (step S220). , wherein the random access preemptive information is transmitted using the above configured context. Then, when receiving the random access preemption information, the wireless access network 120 replies a random access response (RAR) message to the wireless communication device 110 on CC#2 (step S230), Notify that the random access preemptive information has been acknowledged. When the wireless communication device 110 receives the random access response information, it indicates that the non-contention random access procedure has been completed, and CC#2 is already in the startup state. For the wireless communication device 110, CC#2 can be activated before receiving the random access response information. In an embodiment, the controller module 112 can treat CC#2 as being activated upon receiving the previous configuration information; in another embodiment, the controller module 112 can transmit the random access preemption information. CC#2 is considered to be activated; or in still another embodiment, since it may take some time to process the random access response information after receiving the random access response information, the controller module 112 may receive CC#2 is considered to have been after a predetermined time interval after the random access response message start up. After CC#2 is started, the wireless communication device 110 can receive data and control signals from the physical downlink sharing channel and the physical downlink control channel on the CC#2, and can execute the channel quality indicator (CQI). Measurement. In addition to initiating CC#2, the non-contention random access procedure of the present invention also allows the wireless access network 120 to tune the timing of wireless communication with the wireless communication device 110 in the uplink direction (timing). ). That is, the wireless access network 120 can determine the timing shift of the wireless communication with the wireless communication device 110 according to the random access preemption information, and then use the timing shift to adjust the wireless communication in the uplink direction. Timing.

It should be noted that the random access response information may also be transmitted on other component carriers that are activated and not other than CC#2, that is, other component carriers than the component carriers used to transmit the random access preemption information. And the random access response information may include confirmation information for the plurality of wireless communication devices. In another embodiment, the random access response information may be transmitted on CC#1 or another component carrier that has been activated. However, in some cases, there may be multiple wireless communication devices respectively on different component carriers. The same preamble is configured, and the wireless communication devices receive the random access response information transmitted by the foregoing on the same component carrier. For example, the first wireless communication device is configured with the first preamble. And transmitting the random access preemption information on CC#2 using the first preamble, and the second wireless communication device is also configured with the first preamble, and transmitting the random access preemption information on CC#1 using the first preamble, Later, both the first and second wireless communication devices receive the random access response information transmitted using the first preamble at CC#1. Therefore, more The wireless communication device uses the same preamble to perform random access preemptive information transmission. This situation will cause the ambiguity of the acknowledgment information in the random access response information, that is, the wireless communication devices will consider the random storage. The response information is used to confirm the random access preemption information previously transmitted, but the random access response information is used to confirm the random access preemption information transmitted by the first wireless communication device on CC#2. In order to solve the problem of ambiguity, when the first and second wireless communication devices are configured with the same component carrier or the activated component carrier, the wireless access network 120 can avoid the same configuration before the first and the first The second wireless communication device enables the wireless communication device to perform the transmission of the random access preemptive information using the unique preamble. Similarly, the transmission of the random access response information will be performed using the unique preamble. Another method for solving the ambiguity problem is that the user equipment identification (UE ID) of the wireless communication device 110 or the base station radio network temporary identifier (Cell-Radio network Temporary Identifier) can be used by the wireless access network 120. , C-RNTI) scrambling the random access response information. Specifically, the scrambling process refers to cyclic redundancy check of the Downlink Control Information (DCI) under the random access response information. The code (Cyclic Redundant Check, CRC) is disturbed. Since the user device identification code or the base station radio network temporary identifier can be used to clearly identify a wireless communication device, the wireless communication device receiving the random access response information can clearly identify whether the random access response information is used. Confirm the random access preemption information previously transmitted, that is, the wireless communication device is only available The user device identification code or the base station radio network temporary identifier successfully de-scrambles the received random access response information, indicating that the random access response information is used to confirm the previously transmitted random access first. Accounting for information; otherwise, if the user device identifier or the base station radio network temporary identifier cannot successfully descramble the received random access response information, it indicates that the random access response information is not used to confirm The random access preemption information previously transmitted, so the wireless communication device can ignore the random access response information.

Figure 3 is a sequence diagram of information of a contention random access procedure according to an embodiment of the invention. Similar to the embodiment shown in FIG. 2, the wireless access network 120 is an evolved universal terrestrial wireless access network, and the wireless communication device 110 is a user device. First, for the wireless communication device 110, there are already established CC#1 and CC#2, wherein CC#1 is set as the primary component carrier (also referred to as PCC in the figure), and CC#2 is set as the secondary. Component carrier (also referred to as SCC in the figure). It should be noted that since CC#1 is the primary component carrier, CC#1 is already in the startup state, and CC#2 is in the non-boot state. In order to activate CC#2, the wireless communication device 110 transmits a random access preemption information to the wireless access network 120 on CC#2 (step S310), wherein the random access preemptive information is used by the wireless access network. The road 120 broadcasts one of the previous preamble pools for transmission. In particular, after transmitting the random access preemption information, the wireless communication device 110 can be activated by CC#2, and activates a disable timer to count one of the startup time intervals of CC#2 (step S320). When receiving the random access preemption information, the wireless access network 120 replies with a message on CC#2. The machine accesses the response information to the wireless communication device 110 (step S330). However, since the wireless communication device located in the range of the signal of the wireless access network 120 can obtain the foregoing corpus, a plurality of wireless communication devices may use the same preamble to perform random access preemptive information transmission. Accordingly, the wireless communication device 110 further performs a schedule transmission indicating that its user device identification code or base station radio network temporary identification is transmitted to the wireless access network 120 (step S340). Upon receiving the scheduled transmission, the wireless access network 120 replies a contention resolution information to the wireless communication device 110 on CC#2 (step S350), wherein the contention resolution information is a user device including the wireless communication device 110. The identification code or the control element of the media access control of the base station radio network temporary identification. In another embodiment, the contention resolution information can be transmitted on another component carrier that has been activated. After transmitting the contention resolution information, the wireless access network 120 activates CC#2 and starts a disable timer to count one of the startup time intervals of CC#2 (step S360). Next, upon receiving the contention resolution information, the wireless communication device 110 restarts its deactivation timer based on the contention resolution information (step S370). Specifically, the restarting step of the deactivation timer is performed because the control element of the media access control includes the user device identification code of the wireless communication device 110 or the temporary identification of the base station radio network, that is, If the control element of the media access control includes the user device identifier of the wireless communication device 110 or the base station radio network temporary identifier, it indicates that the contention resolution information in step S350 is transmitted for the wireless communication device 110, so The competitive random access procedure of the present invention has been completed. At the same time, the wireless access network 120 also initiates CC#2 after transmitting the contention resolution information. A timer is disabled to enable the startup time interval of CC #2 to maintain synchronization between the wireless communication device 110 and the wireless access network 120. In another embodiment, the wireless communication device 110 and the wireless access network 120 can wait for a predetermined length of time before starting or restarting the disable timer, so that the wireless communication device 110 can have sufficient time to process the received competition. Solve the information. Alternatively, the wireless communication device 110 may not activate the deactivation timer after transmitting the random access preemption information, and wait until the control element of the media access control is received and the control element of the media access control includes its user. When the device identification code or the base station radio network is temporarily identified, the above-mentioned deactivation timer is restarted.

Similar to the embodiment shown in FIG. 3, the wireless access network 120 is an evolved universal terrestrial wireless access network, and the wireless communication device 110 is a user device. First, for the wireless communication device 110, there are already established CC#1 and CC#2, wherein CC#1 is set as the primary component carrier (also referred to as PCC in the figure), and CC#2 is set as the secondary. Component carrier (also referred to as SCC in the figure). It should be noted that since CC#1 is the primary component carrier, CC#1 is already in the startup state, and CC#2 is in the non-boot state. In order to activate CC#2, the wireless communication device 110 transmits a random access preemption information to the wireless access network 120 on CC#2 (step S410), wherein the random access preemptive information is used by the wireless access network. The road 120 broadcasts one of the previous episodes in the previous episode. In particular, after transmitting the random access preemption information, the wireless communication device 110 can be activated by CC#2, and activates a disable timer to time one of the CC#2 starts. Inter interval (step S420). Upon receiving the random access preemption information, the wireless access network 120 replies a random access response message to the wireless communication device 110 on CC#2 (step S430). However, since the wireless communication device located in the range of the signal of the wireless access network 120 can obtain the foregoing corpus, a plurality of wireless communication devices may use the same preamble to perform random access preemptive information transmission. Accordingly, the wireless communication device 110 further performs a schedule transmission indicating that its user device identification code or base station radio network temporary identification is transmitted to the wireless access network 120 (step S440). Upon receiving the scheduled transmission, the wireless access network 120 replies a contention resolution information to the wireless communication device 110 on CC#2 (step S450), wherein the contention resolution information is transmitted through the physical downlink control channel. The control information is transmitted, and the downlink control information is subjected to the scrambling process via the user device identification code of the wireless communication device 110 or the temporary identification of the base station radio network. It should be noted that the radio access network 120 can configure the downlink resource block on the CC#2 through the downlink control information, so that the wireless communication device 110 can receive the downlink data. In another embodiment, the contention resolution information may be downlink control information including one component carrier indicator, and the downlink control information is transmitted on another component carrier that has been activated, where the downlink is on the other component carrier. The resource block is configured to the wireless communication device 110 through the downlink control information. Specifically, one of the component indicator indices, such as one of the carrier indication fields, may be used to indicate the downlink resource block on the other component carrier. After transmitting the contention resolution information, the wireless access network 120 activates CC#2 and starts a disable timer to count one of the startup time intervals of CC#2 (step S460). Then, when the competition resolution information is received, The wireless communication device 110 then restarts its deactivation timer based on the contention resolution information to synchronize with the deactivation timer of the radio access network 120 (step S470). Specifically, the restarting step of the deactivation timer is performed because the user device identification code of the wireless communication device 110 or the base station radio network temporarily identifies the downlink control information to be descrambled, or The downlink control information should be performed including one of the component carrier indicators indicating CC#2, that is, if the wireless communication device 110 uses its user device identification code or the base station radio network temporary identifier to successfully solve the downlink control information. After the scrambling process, or the wireless communication device 110 successfully decodes the downlink control information received on another component carrier that has been activated, and the downlink control information includes a component carrier indicator indicating CC#2, the step S450 is indicated. The contention resolution information in the message is transmitted for the wireless communication device 110, so the competitive random access procedure of the present invention has been completed. In another embodiment, the wireless communication device 110 and the wireless access network 120 can wait for a predetermined length of time before starting or restarting the disable timer, so that the wireless communication device 110 can have sufficient time to process the received competition. Solve the information. Alternatively, the wireless communication device 110 may not activate the deactivation timer after transmitting the random access preemption information, and wait until the received downlink control information includes its user device identification code or the base station radio network temporary identifier. When the indicator component of one of CC#2 is included, the above-mentioned deactivation timer is restarted.

Component carrier (also referred to as SCC in the figure). It should be noted that since CC#1 is the primary component carrier, CC#1 is already in the startup state, and CC#2 is in the non-boot state. In order to activate CC#2, the wireless communication device 110 transmits a random access preemption information to the wireless access network 120 on CC#2 (step S510), wherein the random access preemptive information is used by the wireless access network. The road 120 broadcasts one of the previous episodes in the previous episode. In particular, after transmitting the random access preemption information, the wireless communication device 110 can be activated by CC#2, and activates a disable timer to count one of the startup time intervals of CC#2 (step S520). Upon receiving the random access preemption information, the wireless access network 120 replies a random access response message to the wireless communication device 110 on CC#2 (step S530). However, since the wireless communication device located in the range of the signal of the wireless access network 120 can obtain the foregoing corpus, a plurality of wireless communication devices may use the same preamble to perform random access preemptive information transmission. Therefore, the wireless communication device 110 further performs scheduling transmission of one of its user device identification code or base station radio network temporary identification to the wireless access network 120 (step S540).

In another embodiment, the contention resolution information may be an uplink grant information including one component carrier indicator, and the uplink grant information is transmitted through a control channel (eg, a physical downlink control channel in a long term evolution system, or other wireless storage). The control channel in the technology is transmitted to another component carrier that has been activated, and the uplink resource block on the other component carrier is configured to the wireless communication device 110 through the uplink grant information. Specifically, an uplink resource block on another component carrier may be indicated using a component carrier metric, such as one of the carrier indication fields. After transmitting the contention resolution information, the wireless access network 120 activates CC#2 and starts a disable timer to count one of the startup time intervals of CC#2 (step S560). Then, when receiving the contention resolution information, the wireless communication device 110 restarts its deactivation timer according to the contention resolution information to synchronize with the deactivation timer of the radio access network 120 (step S570). Specifically, the restarting step of the deactivation timer is performed by the user device identification code of the wireless communication device 110 or the temporary identification of the base station radio network to successfully perform the descrambling processing of the uplink promise information, or The uplink grant information should be performed including a component carrier indicator indicating CC#2, that is, if the wireless communication device 110 uses its user device identifier or base. The ground radio network temporarily identifies that the uplink grant information is successfully descrambled, or the wireless communication device 110 successfully decodes the uplink grant information received on another component carrier that has been activated and the uplink grant information includes If there is a component carrier index indicating CC#2, it means that the contention resolution information in step S550 is transmitted for the wireless communication device 110, so the competitive random access procedure of the present invention has been completed. In another embodiment, the wireless communication device 110 and the wireless access network 120 can wait for a predetermined length of time before starting or restarting the disable timer, so that the wireless communication device 110 can have sufficient time to process the received competition. Solve the information. Alternatively, the wireless communication device 110 may not activate the deactivation timer after transmitting the random access preemption information, and wait until the received uplink grant information includes its user device identification code or the base station radio network temporary identifier. When the indicator component of one of CC#2 is included, the above-mentioned deactivation timer is restarted.

Before the timing alignment timer expires, the wireless communication device 110 can monitor the downlink control channel (eg, a physical downlink control channel in a long term evolution system, or a control channel in other wireless access technologies) and a downlink shared channel (eg, The entity in the LTE system shares the control channel or the shared channel in other RATs to receive downlink control information, uplink grant information, and downlink data on the corresponding component carrier, and then on the corresponding component carrier. The confirmation information is transmitted to the wireless access network 120 to notify that the downlink control information or the uplink promise information and the downlink data have been received through the downlink control channel and the downlink shared channel, respectively. In another embodiment, the timing alignment timer can be initiated in response to receiving Timing Advance Command (TAC) information from the wireless access network 120. Later, when the timing alignment timer expires, the wireless communication device 110 stops the deactivation timer corresponding to CC#2 (step S710), and then, the wireless communication device 110 stops monitoring the downlink control channel on CC#2. The channel is shared with the downlink (step S720). Finally, the wireless communication device 110 disables CC#2 again (step S730). Similarly, at the wireless access network 120 end, when its timing alignment timer expires, CC#2 is deactivated and the deactivation timer corresponding to CC#2 is stopped (step S740), thus, Successfully completed the CC#2 deactivation process.
