Description of the Invention: [Technical Field of the Invention] The present invention relates generally to a cellular communication system, and more particularly to a method and apparatus for managing multiple carrier communications. [Prior Art] The Global System for Mobile Communications (Hybrid) communication system provides communication services to mobile and broadcast devices through one of the base stations. In the GSM system, time slots and wireless block frames are transmitted and received at the mobile station by using time division multiplexing. Although the GSM system initially provided voice communication services, it has also been involved in providing data communication services. Standards such as General Packet Radio Service (GpRS) and Global Evolution Enhanced Data (EDGE) further define protocols for data communications within GSM-based systems. Access terminals (sometimes referred to as mobile devices, portable devices, and other names) communicate via channels in the uplink and downlink directions. To increase performance, some access terminals use receive diversity techniques in which two or more antennas are used to receive signals transmitted over the signal path. At least some of the incoming signals can be received at a higher quality due to differences between the antennas such as the antenna position. For example, due to the multiple decay characteristics of the communication path, multiple signals can be destructively combined into one antenna and can also be destructively combined with another antenna. However, by using receive diversity, the opportunity to receive a higher quality signal has increased. In some reception diversity scenarios, signal combinations from multiple antennas are used to improve signal quality. As the GSM system evolves to provide increased data and voice services, the demand for bandwidth and system capacity increases. In a multi-carrier communication system, the 147073.doc 201029361 signal is transmitted at different carrier frequencies by using multiple channels. The receiver receives multiple channels simultaneously by multiple antennas resulting in an increased total bandwidth. The conventional system does not include a method for achieving versatility and multi-channel communication in a single-access terminal using multiple antennas. Accordingly, a need exists for an apparatus and method for managing multiple carrier communications in a GSM communication system. SUMMARY OF THE INVENTION An embodiment is a transmitter configured to transmit a message to a pick-up terminal to command the pick-up terminal to switch between a diversity mode and a multi-carrier mode. In the diversity mode, each of the plurality of antenna modules receives a single carrier signal transmitted at a single carrier frequency. In the multiple carrier mode, one of the plurality of antenna modules receives a first multiple carrier signal transmitted at a first carrier frequency and a second antenna module receives one The second multiple carrier signal transmitted by the second carrier frequency. Another embodiment is a method for managing communications in a communication system, the method comprising transmitting a message to a pick-up terminal, thereby commanding the pick-up terminal to be in a diversity mode and a multi-carrier mode Switch between. In the diversity mode, each of the plurality of antenna modules receives a single carrier signal transmitted at a single carrier frequency. In the multiple carrier mode, one of the plurality of antenna modules receives a first multiple carrier signal transmitted at a first carrier frequency and a second antenna module receives one The second multiple carrier signal transmitted by the second carrier frequency. Yet another embodiment is a pick-up terminal in a wireless communication system, 147073.doc • 4-201029361 The pick-up terminal is configured to respond to a message instructing the pick-up terminal to be in a variety Switch between the mode and a multi-carrier mode. In the multiplicative mode, each of the plurality of antenna modules receives a single carrier signal transmitted at a single carrier frequency. In the multiple carrier mode, one of the plurality of antenna modules receives a first multiple carrier signal transmitted at a first carrier frequency and a second antenna module receives one or one The second multiple carrier signal transmitted by the second carrier frequency. [Embodiment] FIG. 1 is a block diagram of a GSM communication system 1A according to an exemplary embodiment of the present invention. The word "exemplary" is used herein to mean "as an example, example or description,". Therefore, any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. The various functions and operations of the blocks described in the GSM System 1 can be implemented in any number of devices, circuits or components. Two or more functional blocks may be integrated into a single device and the functionality described as being performed in any single device may in some cases be implemented across several devices. Although the GSM system 100 includes features, information, and other aspects not explained by the current GSMEDEG Radio Access Network (GERAN) standard, in the exemplary embodiment, the GSM system 100 still operates in accordance with GERAN communication technology. Accordingly, the exemplary embodiment provides an example of a variation of the current letter standard. The GSM system 100 includes a GSM network 114 that provides communication services to a plurality of access terminals 102. A pick-up terminal 1 2 can be any of several types of devices that facilitate communication of the voice and/or data with the GSM network 114. The pick-up terminals 102 (sometimes referred to as handsets, mobile stations 147073.doc 201029361 (MS), wireless communication devices, and other terms) include devices such as cellular telephones and wireless personal digital assistants (PDAs). The GSM network 114 includes a plurality of base stations 1 and 4 and other infrastructure, databases, and post-networks that exchange wireless signals with the receiving terminal 102. The GSM network 114 controls the communication of the receiving terminals by using command and control messages in accordance with a communication protocol defined generally by a standard protocol. The base station 104 and the GSM 114 include transmitters for transmitting voice, data and signal messages to the access terminal 1102. The receiver in the base station 104 receives the self-receiving terminal! 〇2 transmitted voice, data and signal messages. Signals transmitted by one or more of the base stations 1-4 in the GSM network 114 are received by a receiver 116 via an antenna system 120, which includes at least one antenna 106, 108. One or more of the access terminals 1〇2 may include an antenna system 120 having a plurality of antennas 106,108. A receiving terminal 102 having a plurality of antennas 1, 6 and 108 can utilize diversity multiplexing techniques to improve receiver performance. During the diversity operation, multiple antennas 1 〇 6, 1 〇 8 are tuned to the same carrier frequency to receive multiple patterns of a transmission signal. A performance improvement from the combination of signals received via an additional antenna or signals received from one or more antennas 106, 1 and 8 to obtain additional information. In some cases, the carrier frequency of the received signal may change during transmission. This situation occurs where frequency hopping is used', for example, the carrier frequency (a signal transmitted by it) changes on a per TDMA frame basis in a predetermined order. Thus, the plurality of antennas 106, 108 remain tuned to the same signal and follow the "frequency hopping" carrier frequency. As mentioned above, multi-carrier communication provides a technique for increasing the peak data rate of downlink communications within the current GERAN infrastructure 147073.doc 201029361. In a multi-carrier mode, at least two antennas 106, 1 〇 8 receive different signals at different carrier frequencies. By using a plurality of carrier signals, more bandwidth can be used to receive the message, thereby increasing the received data transmission rate at the receiving terminal 102. According to an exemplary embodiment, the pick-up terminal 102 is capable of operating in a Receive Diversity (RXDIV) mode and a Multiple Carrier mode. The pick-up terminal 1 2 includes an antenna system 120 comprising a plurality of antennas 1 〇 6, 1 〇 8. In the exemplary embodiment, antenna system 12A includes a first antenna 1〇6 and a second antenna 108. The multicarrier and RXDIV receiver 116 includes a plurality of suitable hardware, software and/or firmware for receiving a signal by at least two antennas 1〇6, 1〇8 in the RXDIV mode. In addition, the receiver U6 is configured to receive a first signal 110 at the first carrier frequency (C1) by one of the antennas 106, and receive a second at the second carrier frequency by the other antenna 1 〇8. Signal 112. Controller 118 is any combination of hardware, software and/or firmware configured to perform the functions described herein and to facilitate the overall functionality of the receiving terminal. The controller 118 can include any number and combination of circuits, electrical devices, memory, and processing devices. The processing devices can include a single processor, a microprocessor, a processor configuration, or a logic gate. By using discrete components, controller j 18 can be implemented, at least in part, as part of an integrated circuit or as part of an application specific integrated circuit (ASIC). The software and hardware running on the exemplary real towel (4) perform the control functions described herein. The controller m generates a control signal based on the command received from the gsm network ιι4 to configure the receiver. 147073.doc 201029361 In addition to configuring the hardware and calling the code, the controller 118 generates a response, confirmation, and request message. In the exemplary embodiment, the pick-up terminal 102 is still in the receive diversity mode as an erroneous configuration. In response to a multiple carrier switching command message received from the GSM network 1] 4, the receiving terminal switches to the multiple carrier mode. In response to a RXDIV& change command message received from the GSM network 114, the pick-up terminal switches back to the receive diversity mode. When receiving the multi-carrier switching command message, the receiving terminal 1 2 generates a suitable control signal and configures the receiver 116 to receive a first signal 110 at the first carrier frequency by the first antenna 106 and A second signal 112 at a second carrier frequency is received by the second antenna 108. In the exemplary embodiment, the receiver includes a receiver branch coupled to each of the antennas 108, 108 to allow each receiver branch to tune to a different carrier frequency. An appropriate receiver branch instance includes one or more mixers for shifting the incoming signal frequency to a desired intermediate frequency or to a fundamental frequency by mixing the incoming signal with a suitable mixed signal. The frequency offset signal is further processed and demodulated by other receiver 116 components. In some cases, each receiver branch may include a chopper in addition to the filter shared by the plurality of receiver blades. Each receiver branch responds to the control signal to tune a specified carrier frequency. In the Receive Diversity mode, the receiver branches are tuned to the same frequency, allowing a plurality of patterns of a single signal to be received. In the multiple carrier mode, at least one of the receiver branches is tuned to a different carrier frequency than the other receiver branch. Correspondingly, in the receive diversity mode, the receiver 116 can tune multiple receiver branches to a single carrier frequency, and in the multiple carrier mode, 147073.doc 201029361 in response to the controller, the receiver 116 can tune the receiver branch To different carrier frequencies. In some cases, other techniques may be used in the receiver 16 to facilitate the multiple carrier and diversity capabilities. Although the description herein is limited to two antennas and two carriers' the discussion can be applied to any configuration including m diversity branches and n carriers (where nSm). 2 is a block diagram of signal messages 202. 212 exchanged between GSM network 114 and access terminal 102 in accordance with the exemplary embodiment. The signal messages 202-212 may be incorporated into conventional signal messages currently defined in the GERAN specification or may be implemented as additional messages in the GERAN specification, wherein the portions of the messages 202-212 may be implemented on a plurality of conventional signal messages and two or two More than one message 202_212 can be implemented in a single message. In an exemplary embodiment, GSM network 214 is notified by multiple carrier errors and receiving diversity capabilities of receiving terminal 102. When the receiving terminal sends a capability message 204 indicating at least the receiving diversity and multiple carrier capabilities of the receiving terminal, the GSM network is notified to receive the multiple carriers of the terminal 1 and the diversity capability of the receiving terminal. . The capability message 2〇4 is further described with reference to FIG. If the receiving terminal has RXDIV capability and multiple carrier capabilities, the GSm network manages resources by commanding the receiving terminal to switch between Rxdiv mode and multiple carrier mode. The determination of the handover may be based on any of a number of factors, for example, 5, the available bandwidth, the amount of data to be received by the receiving terminal, the number of other adjacent receiving terminals, and the data transmission rate of other receiving terminals. Other capabilities in the region to access the terminal or rely on any other reason for the network algorithm. 147073.doc 201029361 The GSM network transmits a multiple carrier switching command 206 to command the access terminal to switch from the received diversity mode to the multiple carrier mode. An example of a suitable multiple carrier switching command 206 includes a modification of a message according to the GERAN specification, such as packet downlink assignment, packet time slot reassembly, or the like. After the receiving terminal successfully completes the switching from the receiver diversity mode to the multiple carrier mode, the receiving terminal can transmit a handover confirmation message 208 indicating that the handover is successful. An example of a handover confirmation message 208 includes a message according to the current GERAN specification, such as the packet downlink acknowledgement message. In some cases, no confirmation is sent. When the GSM network determines that the receiving terminal has to return to receive diversity mode, the GSM network transmits an RXDIV switching command 210. An example of a suitable RXDIV handover command 206 includes a modification or extension of one of the messages according to the current GERAN specification, such as packet downlink assignment, packet time slot reassembly, or the like. The access terminal can transmit a handover confirmation message 212 indicating that the handover from the multiple carrier mode to the reception diversity mode is successful. In some cases, no confirmation is sent. FIG. 3 is a block diagram of a capability message 204 in accordance with the exemplary embodiment. As explained above, the access terminal transmits the capability message 204 indicating the capability of multiple carriers and receiving diversity capabilities. The capability message 204 can include an RXDIV indication 302 and a multiple carrier indication 304. In the exemplary embodiment, capability information 204 includes a one-bit RXDIV indication 203 and a one-bit multi-carrier indication 340 and other indications 306 that describe other capabilities of the terminal. 147073.doc -10· 201029361 Thus, in the exemplary embodiment, a single bit indicates whether the receiving terminal has a capability of receiving diversity and a single bit indicates whether the receiving terminal has multiple carriers ability. In some cases, the indications may include multiple bits to convey additional information. An example of an appropriate capability message 2〇4 includes a message based on the MS wireless access capability message, in which the bit is received or added to the current format to deliver the rXDIV and multiple carrier capabilities. In some cases 'Only one bit multicarrier indicator 3〇4 is included in I's capability message 204' and it is assumed that all mobile terminals capable of multiple carriers also imply RXDIV capabilities. 4 is a block diagram of a multiple carrier switching command message 2〇6 in accordance with the exemplary embodiment. The multiple carrier switching command message 〇6 includes at least one instruction indicating that the receiving terminal has to switch to the multiple carrier mode. In the exemplary embodiment, the multiple carrier switching command message 〇6 includes a multicarrier switching indication 402, a multicarrier channel indication 4〇4, and a time slot with multiple carriers to which the terminal is assigned. Configure other related commands. An example of such a command φ includes a modification or extension of a message according to the current GERAN specification, such as a packet downlink assignment message or a packet time slot reassembly message, or the like. Figure 5 is a block diagram of an RXDIv Handover Command message 2A in accordance with the exemplary embodiment. The RXDIV handover command message 21A includes at least an instruction indicating that the access terminal has to switch to the reception diversity mode. In the exemplary embodiment, the RXDIV Handover Command message 2 includes an RXDIV Handover Indication 502 single carrier channel indication 504 and other commands associated with a time slot configuration for a single carrier (terminal assigned to eight). An example of such a command includes 147073.doc 201029361 - A modification or extension of a message according to the current GERAN specification, such as a packet downlink assignment message or a packet time slot reassembly message, or a similar message. The single carrier channel indication 504 indicates a single channel that will be used to transmit signals to the receiving terminal. 6 is a flow diagram of a method for managing multiple carrier communications in a wireless communication system in accordance with an illustrative embodiment of the present invention. The method can be performed by using any combination of hardware, software, and/or firmware. In the exemplary embodiment, the method is performed in one of the base stations or other network entities 1-4 in the GSM network 114. Although the method is discussed with reference to a single access terminal 1 〇 2, it can be performed concurrently with any number of access terminals 102 communicating within the GSM network 114. In step 602, the base station 104 receives a capability message 2〇4 indicating at least the reception diversity and multi-carrier capability of the terminal device 1〇2. At step 604, it is determined whether the pick-up terminal 1 〇 2 has multiple carrier capabilities. If the pick-up terminal 102 does not have multiple carrier capabilities, the multiple carrier management for the particular pick-up terminal 102 is terminated and the method proceeds to step 606. Otherwise, the method continues at step 608. @ At step 608, it is determined whether the pick-up terminal 102 has to switch to the multi-carrier mode. As described above, in the exemplary embodiment, the pick-up terminal 102 does not perform the receive diversity mode and thus switches to the multi-carrier mode as determined by the GSM network. This decision can be based on any number of factors and depends on the particular implementation of the GSM system and system capabilities. The handover decision can be based on any of a number of factors, for example, the available bandwidth, the amount of data to be received by the pick-up terminal 102, and the number of other nearby access terminals 147073.doc • 12· 201029361 (102) , the data transfer rate of other terminals (10), the ability to access the terminal (102) in the area, or any other reason that depends on the network algorithm. If it is determined that the receiving terminal 102 is still in receive diversity mode (RXDIV), then the method returns to step 6-8 to continue monitoring the network. If the terminal terminal 1〇2 is to be switched to the multi-carrier mode, the method continues at step 610. In step 610, the multiple carrier switch command message 2〇6 is transmitted to the pick-up terminal 102. In the exemplary embodiment, the multiple carrier switching command message 206 is transmitted by a transmitter within a base station 104. At step 612, the switch confirmation 208 message is received from the pick up terminal. In this example embodiment, the handover confirmation message 2〇8 is received by a receiver in a base station 1〇4. If the confirmation message 2〇8 is not received, the base station 1〇4 is dedicated to retransmission or parsing procedures. At step 614', it is determined whether the access terminal ι2 needs to switch to the single carrier reception diversity mode. If the GSM network 114 determines that the terminating terminal has to switch to the RXDIV mode due to active resource allocation or other reasons, the method continues at step 616. Otherwise, the method returns to step 614 to continue monitoring system 100. At step 61, the RXDIV switch command message 210 is transmitted to the pick-up terminal. As described above, in the exemplary embodiment, the rXDIV switch command message 210 includes a single carrier channel indication 5〇4. At step 618, a handover confirmation message 212 indicating successful handover from the multiple carrier mode to the reception diversity mode is received. If the confirmation message 208 is not received, the base station 104 is committed to retransmission or parsing of the program. The party 147073.doc 13 201029361 then returns to step 608 to monitor the system to determine that the pick-up terminal 1 〇 2 must switch to the multi-carrier mode. In the case of - τ τw 4 , the confirmation message may not be used.
