 The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without departing from the inventive work are all within the scope of the present invention.

 A person skilled in the art can understand that the drawings are only a schematic diagram of a preferred embodiment, and the modules or processes in the drawings are not necessarily required to implement the invention.

 Various aspects are described herein in connection with a terminal and/or a base station.

 A terminal, a device that provides voice and/or data connectivity to a user, including a wireless terminal or a wireless terminal. The wireless terminal can be a handheld device with wireless connectivity, or other processing device connected to a wireless modem, and a mobile terminal that communicates with one or more core networks via a wireless access network. For example, the wireless terminal can be a mobile telephone (or "cellular" telephone) and a computer with a mobile terminal. As another example, the wireless terminal can also be a portable, pocket, handheld, computer built-in or in-vehicle mobile device. For another example, the wireless terminal can be a mobile station (English: mobile station), an access point (English: access point), or user equipment (English: user equipment, called UE).

A base station may refer to a device in an access network that communicates with a wireless terminal over one or more cells over an air interface. For example, the base station may be a base station in GSM or CDMA (base transceiver station, called BTS), or a base station in WCDMA (in English: NodeB), or an evolved base station in LTE (in English) : evolutional Node B, called eNB or e-NodeB), or a base station in a subsequent evolved network, which is not limited by the present invention. Set.

 In a wireless communication system, usually there is only one carrier in each cell under the base station, and the terminal can only perform data transmission and reception in one cell (on the carrier) at the same time. The carrier may be a frequency carrier; it may also occupy part of the bandwidth of the wireless communication system; it may also be a minimum assignable unit, such as multiple time domains on multiple schedulable subcarriers in a subframe. In the long term evolution system

In LTE, the maximum bandwidth of the carrier is 20MHz. In the advanced long-term evolution system (called LTE-A), the peak rate of the wireless communication system is greatly improved compared to LTE, and it is required to achieve downlink IGbps and uplink 500Mbps, so the 20MHz transmission bandwidth has been This demand cannot be met. In order to provide a higher transmission rate, LTE-A uses carrier aggregation technology. The above carrier aggregation technology refers to that the terminal can combine multiple carriers at the same time and simultaneously perform data transmission on the above carrier, thereby improving the data transmission rate. In order to ensure that the terminal can work under each aggregated carrier in LTE-A, the bandwidth of each carrier does not exceed 20 MHz at the maximum. In LTE-A, the number of carriers that can be aggregated by the terminal does not exceed five, that is, the network side can perform data transmission with the terminal on five carriers at the same time.

 In various embodiments of the present invention, variable bandwidth is provided to the terminal by using carrier aggregation techniques on multiple carriers to increase the effective bandwidth of the wireless communication system. As another example, the carrier aggregation techniques described above can also be implemented in a variety of wireless communication technologies operating in different bandwidth and/or duplex modes. The above carrier aggregation technology can efficiently create a wider band channel with higher peak throughput, and can also support terminals of conventional bandwidth (such as 20 MHz transmission bandwidth) and/or non-traditional bandwidth (such as 100 MHz transmission bandwidth). Isomer mixture. Depending on system load, peak rate, or quality of service requirements, carrier aggregation techniques can be used asymmetrically for the downlink and/or uplink. Those skilled in the art will appreciate that the downlink refers to a channel through which a base station transmits data to a terminal, and the uplink refers to a channel through which a terminal transmits data to a base station.

In a different embodiment of the present invention, for a terminal with carrier aggregation capability, the base station may configure a working carrier set for the terminal according to the sum of the maximum rates of all services requested by the terminal. In the above working carrier set, the base station selects a carrier for the terminal as the terminal. The primary carrier (English: primary carrier, the remaining carrier in the working carrier set serves as the secondary carrier of the terminal (English: secondary carrier). Those skilled in the art can understand that the primary carrier may also be referred to as a primary cell. The primary carrier may also be referred to as a secondary cell (in English: secondary cell). The primary carrier may be used to transmit control signaling and user plane data. The secondary carrier may be used to transmit a small number of control plane signaling. Or media information. By separating the control channel and the data channel for media information, the base station has greater flexibility in dynamically allocating radio frequency spectrum resources or available bandwidth to the terminal. For example, the terminal can receive relevant media by detecting the control channel. Configuration parameters of the changes made by the channel. With a plurality of different channels, it is possible to propagate the changes occurring on the channel to the affected terminals more likely.

 In a different embodiment of the present invention, the base station can allocate a primary carrier to the terminal and/or a secondary carrier of no more than four by using the carrier aggregation technology. The state of the above secondary carrier changes depending on the change in the bandwidth required by the terminal. For example, when the bandwidth required by the terminal increases, the number of secondary carriers that the base station provides to the terminal in the activated state also increases to provide the appropriate bandwidth to the terminal. For example, when the bandwidth required by the terminal is reduced, the number of secondary carriers that the base station provides to the terminal in the activated state is also reduced, so as to release the radio frequency spectrum resource or the available bandwidth for use by other terminals. Therefore, according to the availability of the base station resources, the different embodiments of the present invention can dynamically allocate the secondary carrier at any time to adapt to the bandwidth demand change of the terminal and dynamically balance the bandwidth allocation to maximize bandwidth utilization.

 Hereinafter, each specific embodiment will be described in detail with reference to the drawings.

 A method for allocating a multi-carrier resource according to the first embodiment of the present invention, as shown in FIG. 1, includes:

S101: The base station allocates a primary carrier and a secondary carrier to the terminal, and is used to implement communication between the base station and the terminal.

S102: The base station or the terminal releases a physical uplink control channel (English: physical uplink control channel, called PUCCH) resource allocated to the terminal and used for the secondary carrier according to a set time of the deactivation timer. And a sounding reference signal (English: sounding reference signal, SRS) resource for interrupting the base station and the terminal based on the Secondary carrier communication.

 In S102, the base station may acquire channel resources for transmitting control signaling in the same PUCCH resource, which are used for the primary carrier and the secondary carrier, respectively. Moreover, the base station may also obtain channel resources for transmitting SRS in different SRS resources, which are used for the primary carrier and the secondary carrier respectively. The SRS is used to detect a physical uplink shared channel (English: physical uplink shared channel, called PUSCH) to provide reliability of PUSCH selective scheduling.

 In this embodiment, the base station may have a base station scheduler, configured to control transmission of uplink and downlink data, and when the base station scheduler determines the scheduling terminal, it shall notify through a physical downlink control channel (PDCCH) The resource on which the terminal sends/receives data. The terminal monitors the PDCCH. When detecting that the scheduling information sent by the base station is related to itself, the terminal sends uplink data to the base station on the uplink or downlink data sent by the base station on the downlink according to the indication on the PDCCH. In the active state, the terminal continuously monitors the PDCCH, and parses each subframe related thereto to determine whether it is scheduled. In the deactivated state, the terminal does not monitor the PDCCH to save power. In this embodiment, the activation state refers to a state in which the terminal and the base station maintain communication with each other for a certain period of time, and the deactivation state refers to a state in which the terminal and the base station stop communication with each other for a certain period of time.

In this embodiment, the deactivation timer may be used to indicate release of the PUCCH resource and the SRS resource for the secondary carrier allocated to the terminal. After the deactivation timer is started, if the deactivation timer expires due to no data or signaling transmission on the uplink or downlink, the base station may release the PUCCH resource for the secondary carrier allocated to the terminal and SRS resources to save power consumption, reduce interference, or allocate the above PUCCH resources and SRS resources to other terminals to balance bandwidth allocation between different terminals. For example, when the deactivation timer is started, the terminal does not transmit data to the base station on the uplink during the set time of the deactivation timer, or the terminal does not receive the data transmitted by the base station on the downlink, when it exceeds After the set time of the timer is activated, the deactivation timer may be considered to expire, and the base station releases the PUCCH resource and the SRS resource for the secondary carrier allocated to the terminal. Another example is when the deactivation timer is started, the deactivation timer is set. During the time, the terminal transmits data to the base station on the uplink, or the terminal receives the data transmitted by the base station on the downlink, and the deactivation timer may not be considered to expire. When the set time of the deactivation timer is exceeded, the base station The PUCCH resources and SRS resources for the secondary carrier allocated to the terminal are also not released. For example, in the set time of the deactivation timer, the terminal does not transmit data to the base station on the uplink, or the terminal does not receive the data transmitted by the base station on the downlink, and the terminal may be considered to be in a deactivated state. After the set time of the deactivation timer, the base station releases the PUCCH resource and the SRS resource for the secondary carrier allocated to the terminal. For example, when the communication between the base station and the terminal is stopped, the deactivation timer can start working, and a certain time period is set in the deactivation timer. After the time period is exceeded, the terminal is considered to be deactivated, and the base station releases the allocation to The PUCCH resource and the SRS resource of the terminal for the secondary carrier. Those skilled in the art can understand that the time setting of the deactivation timer, the determination of whether to expire, or the setting of the initial parameters may be based on different requirements of the request of the terminal, the protocol of the operator, or the activity status of the terminal itself. , will not repeat them here.

 In this embodiment, the deactivation timer may be located in a base station or a terminal. For example, the base station may allocate different deactivation timers for different secondary carriers to respectively set the deactivation timers for different secondary carriers according to the communication protocol, the available resources, the terminal activity status, or the number of secondary carriers requested by the terminal, and the like. For the duration, the base station gradually releases the PUCCH resource and the SRS resource for the secondary carrier corresponding to the deactivation timer. Specifically, the base station/terminal actively releases PUCCH resources and SRS resources according to the reduction of the amount of communication data between the terminal and the base station, and is used to implement efficient communication between the terminal and the base station through suitable resources.

In this embodiment, releasing the PUCCH resource and the SRS resource for the secondary carrier may be performed by the base station or the terminal. In addition, the base station adjusts the state of the secondary carrier by adjusting PUCCH resources and SRS resources allocated to the terminal. For example, when the base station releases the PUCCH resource and the SRS resource for the secondary carrier allocated to the terminal, the base station may adjust the secondary carrier from the activated state to the deactivated state. For another example, according to the set time of the deactivation timer, the base station may release the PUCCH resource and the SRS resource for the secondary carrier allocated to the terminal, and The PUCCH resource and the SRS resource are set to an idle state. When the PUCCH resource and the SRS resource are in an idle state, the base station may allocate the released PUCCH resource and the released SRS resource to other terminals, and the base station and the other base station communicate according to the foregoing secondary carrier, so that the base station can balance The available bandwidth between each terminal enables the maximum utilization of bandwidth.

 In this embodiment, the base station determines that the PUCCH resource and the SRS resource for the secondary carrier finally allocated to the terminal may be PUCCH resources and SRS resources required for implementing efficient communication in the communication protocol. For example, when a request for a webpage or other data using a hypertext transfer protocol (HTTP) usually occupies a small bandwidth, or a single primary carrier can process the above request, the base station can release all PUCCH resources allocated to the terminal. And SRS resources. At this time, communication between the base station and the terminal can be based on the primary carrier.

 Therefore, in this embodiment, the secondary carrier can be dynamically allocated according to the availability of the base station resource to adjust the bandwidth requirement of the terminal to dynamically balance the bandwidth allocation to maximize bandwidth utilization.

 The method for allocating a multi-carrier resource according to the first embodiment of the present invention may further include: when the amount of communication between the terminal and the base station increases, the base station acquires a PUCCH resource and an SRS resource for the secondary carrier.

 Optionally, when the amount of communication between the terminal and the base station is reduced, the base station may release the PUCCH resource and the SRS resource for the secondary carrier, and adjust the secondary carrier allocated to the base station from the activated state to the deactivated state. When the amount of communication between the terminal and the base station increases, the base station may acquire the PUCCH resource and the SRS resource for the secondary carrier again.

 Optionally, the base station sends the PUCCH resource and the SRS resource for the secondary carrier to the terminal.

In this embodiment, after the terminal receives the PUCCH resource and the SRS resource allocated by the base station, the terminal may occupy the PUCCH resource and the SRS resource. After the terminal occupies the foregoing PUCCH resource and the SRS resource, the base station may determine whether to allocate the foregoing resource to other terminals according to the set time of the deactivation timer. In this embodiment, the message carrying the PUCCH resource and the SRS resource for the secondary carrier may be a radio resource control (English: radio resource control, RRC) reconfiguration message. A person skilled in the art may understand that the foregoing PUCCH resource and the SRS resource may also be carried in a message sent by another base station to the terminal, and details are not described herein again.

 Optionally, the base station sends a message to the terminal to instruct the terminal to activate the secondary carrier in the deactivated state.

 When the available bandwidth of the terminal is limited or the secondary carrier that the terminal needs to be in the deactivated state provides the appropriate bandwidth, the base station indicates that the secondary carrier in the deactivated state is activated.

 In this embodiment, when the amount of communication data between the terminal and the base station increases, the base station instructs the terminal to activate the secondary carrier in the deactivated state. After the secondary carrier is activated by the terminal, the deactivation timer may be restarted, and the base station re-determines whether the PUCCH resource and the SRS resource need to be released again through the deactivation timer. For example, the base station can restart the deactivation timer by communicating with the terminal on any of the activated secondary carriers. When the deactivation timer expires, the base station releases the PUCCH resource and the SRS resource for the secondary carrier. For another example, when the terminal receives the data related to the hybrid automatic repeat request on any activated secondary carrier, the deactivation timer is restarted, and when the deactivation timer expires, the base station releases the secondary carrier for the secondary carrier. PUCCH resources and SRS resources. It can be understood by those skilled in the art that the deactivation timer can also be restarted by other means, and details are not described herein again.

In this embodiment, the message that the base station sends to the terminal and carries the activated secondary carrier may be a medium access control (media access control, MAC) control unit message. For example, the base station may transmit downlink data to the terminal by using the primary carrier and/or the activated secondary carrier, where the downlink data includes related information indicating that the secondary carrier that has been allocated to the terminal but has not been activated is activated, and the terminal parses the downlink. After the data, the above secondary carrier can be activated. After the activation of the secondary carrier, the terminal may also restart the deactivation timer for the base station to re-determine whether to release the PUCCH resource and the SRS resource again. Those skilled in the art can understand that the foregoing MAC control unit message and RRC reconfiguration message can be simultaneously used by the base station through the same signaling. Send to the terminal to save air interface resources.

 Optionally, the terminal receives the PUCCH resource and the SRS resource sent by the base station, and activates the secondary carrier, to implement communication between the terminal and the base station based on the secondary carrier.

 In this embodiment, after the terminal occupies the PUCCH resource and the SRS resource, the RRC reconfiguration complete message is sent to the base station, where the RRC reconfiguration complete message carries the PUCCH resource and the SRS used by the terminal for the secondary carrier. Confirmation information of the resource. For example, the terminal may send an RRC reconfiguration complete message to the base station through the primary carrier and/or the secondary carrier that has been activated. After receiving the RRC reconfiguration complete message, the base station can confirm that the terminal has successfully occupied the PUCCH resource and the SRS resource for the secondary carrier. It can be understood by those skilled in the art that the acknowledgment information of the PUCCH resource and the SRS resource for the secondary carrier may be carried in other messages to the base station, and details are not described herein.

 Therefore, in this embodiment, the base station allocates the PUCCH resource and the SRS resource for the secondary carrier to the terminal when the communication between the base station and the terminal increases, and the terminal activates the secondary carrier according to the indication of the base station, to Adapt to the bandwidth demand of the terminal and dynamically balance the bandwidth allocation to maximize bandwidth utilization.
