When the downlink-like function is enabled, the user terminal decodes the received downlink packet. If the decoding is correct, it responds to the base station with an ACK. If the decoding fails, the data is sent to the base station. Responding to NACK 'requires the base station to retransmit the packet; when the downlink persistent scheduling service ends, the base station sends a Semi-persistent Scheduling (SPS) resource release indication to the user terminal to notify the user terminal to release all resources allocated to the service. After the user terminal correctly receives the indication, it will respond to the base station with an ACK. For long-term evolution multi-carrier systems, to support a wider system bandwidth than the long-term evolution system, such as 100MHz, the specific implementation includes: A, please refer to Figure 1, directly allocate the spectrum of 100M bandwidth; B, please refer to Figure 2 All the spectrums allocated to the existing system are aggregated and made into a large bandwidth for use in the long-term evolution multi-carrier system. At this time, the uplink and downlink carriers in the system can be asymmetrically configured, and the user may occupy N (N> =1 The carrier transmits downlink, and 201225713 M (M> = 1) carriers perform uplink transmission. Please refer to Figure 3 and Figure 4. The basic transmission scheme of the LTE system (Rel-8), which has been basically completed by the standardization work, is as follows: Frequency Division Duplex (FDD) system and time division duplex (time-divisi〇) n duplex, TDD) are shown in Figure 3 and Figure 4, respectively. For each working carrier, downlink signaling (Signal ing), downlink data, uplink signaling, and uplink data are defined, and the transmission relationship between each other is defined. The two ends of the frequency band occupied by the uplink control signaling are transmitted by using a frequency hopping method, that is, in two time slots (Time Slots, TSs) in a sub-frame (Sub Frame), the uplink control signaling will occupy different frequency bands for transmission; The system reserves a certain amount of resources in the uplink sub-frame for the uplink control channel transmission because the number of control channels to be carried in the uplink sub-block cannot be dynamically learned.

[Embodiment] ▲ The method, device and system for configuring the resource of the uplink control channel of the present invention, "the method includes: Does the base station respond to the uplink carrier on which the user terminal responds? If the uplink control channel resource does not exist, the base station sighs the identifier of the available resource in the mcH and sends it to the user terminal; the user terminal root 201225713 uses the corresponding identifier of the resource, and uses the corresponding The resource is ACK/NACK replied. In an embodiment of the present invention, the base station allocates an uplink control channel resource set, where the resource set includes multiple channel resource numbers for which ACK/NACK responses are available, and the base station determines that the user terminal is performing an ACK/NACK response. On the uplink carrier, whether there is an uplink control channel resource to be PDCCH on the downlink carrier, and an identifier is set in the PDCCH according to the determination result, where the identifier is used to indicate whether the user terminal uses the channel resource in the uplink control channel resource set to perform ACK. /NACK response, and the use of the channel resource element in the set; the user terminal reads the configuration signaling sent by the base station, learns the uplink control channel resource set, detects the PDCCH of the downlink carrier to be responded, and determines according to the set identifier. Whether to use the channel resource in the uplink control channel resource set and the usage of the channel resource element in the set. 5 is a flowchart of a method for configuring an uplink control channel resource according to the present invention. To be compatible with an LTE system, the method for configuring an uplink control channel resource includes the following steps: For an LTE-A carrier aggregation system, An physical uplink control channel (PUCCH) of an uplink carrier responds to ACK/NACK information corresponding to a physical downlink shared channel (PDSCH) on multiple downlink carriers and/or multiple SPS resource release The PDCCH/NACK information of the PDCCH, then 201225713 The user terminal needs multiple uplink control channel resources to perform ACK/NACK response. Step 5 01: The upper layer uniformly allocates an uplink control channel resource set to the user terminal, where the resource set includes multiple channel resource numbers for which the ACK/NACK response is available. The uplink control channel resource set has N>=1 elements corresponding to the available channel resource numbers of the N ACK/NACK responses. The channel resource elements in the set can be shared by multiple user terminals, and the base station restricts the time-phase response of the user terminals using the same channel resource by scheduling, thereby avoiding channel resource collision problems. The resource property in the uplink control channel resource set is semi-continuously scheduled, and the base station configures resources in the uplink control channel resource set through high layer signaling. Step 502: The base station determines whether there is an uplink control channel resource of the PDCCH to be replied to the downlink carrier on the uplink carrier that performs the ACK/NACK response, and sets an identifier in the PDCCH according to the determination result, where the identifier is used to indicate whether the user terminal is Using the channel resources in the uplink control channel resource set to perform ACK/NACK response, and the use of channel resource elements in the set; wherein, if the ACK/NACK response is performed on the uplink carrier, there is 201225713 pending PDCCH on the downlink carrier The uplink control channel resource corresponding to the CCE of the CCE, that is, the uplink control channel resource corresponding to the CCE of the PDCCH on the downlink carrier to be replied is reserved on the uplink carrier that performs the ACK/NACK response, and the resource is used as the ACK/NACK response. Response channel. In this case, it is not necessary to utilize any one of the uplink control channel resource sets allocated by the upper layer; the base station uses the PDCCH to inform the user terminal that the channel resource elements in the set allocated by the higher layer are not used. The method for signaling the PDCCH signaling may be a signaling for newly setting a bit element for the downlink control information (DCI) format carried on all PDCCHs, or signaling of the bit element. Re 1-8 other signaling joint coding in the existing DCI format, and even reuse the signaling in the existing DCI format to represent these N+1 states. However, if there is no uplink control channel resource corresponding to the CCE of the PDCCH on the downlink carrier, the uplink control channel resource corresponding to the CCE of the PDCCH on the downlink carrier to be replied is not reserved on the uplink carrier that performs the ACK/NACK response, Then, an element in the upper control channel resource set allocated by the upper layer needs to be used as the response channel used for the ACK/NACK response. The base station uses the PDCCH to inform the user terminal of the resource element number specifically used in the set. The method for signaling the PDCCH signaling may be signaling for newly setting a bit for the DC I format carried on all PDCCHs, or signaling of the bit and other signaling in the existing DCI format of Re 1-8. Joint coding, even heavy 12 201225713 This N + 1 state is represented by signaling in the existing DCI format. Step 503: The user terminal reads the configuration signaling sent by the base station, learns the uplink control channel resource set, detects the PDCCH of the downlink carrier to be responded, and determines whether to use the channel resource in the uplink control channel resource set according to the set identifier. And the channel resource number used to make an ACK/NACK response. In another embodiment of the present invention, N elements are included in the uplink control channel resource set, and N groups of available channel resource numbers corresponding to the user terminal responding with aCK/nack 'where n>gt = 1 Setting the identifier of the available resource in the pj)cCH includes: setting the signaling of the bit in the downlink control information DC I format carried on the pDCCH for downlink scheduling, where the signaling corresponds to N + 1 state The status indicates a channel resource group in the set of uplink control channel resources for the user terminal to perform ACK/NACK response, each resource group includes multiple available channel resource numbers; and another status is used to indicate the user terminal. The ACK/NACK response is not used for the channel resource group in the upstream control channel resource set. 6 is a schematic diagram of a carrier application for signal transmission in a specific application environment according to the present invention, wherein the user terminal responds to the ACK/NACK information and/or indication corresponding to the PDSCH on the downlink carriers 1, 2, 3, and 4 on the uplink carrier 1 ACK/NACK information of the PDCCH released by the SPS resource. The base station semi-statically allocates N>=1 uplink control channel resource 201225713 source or resource group to the user terminal through RRC signaling. In this embodiment, N=7, indicating that the channel resource set allocated by the upper layer is included. 7 channel resource elements or resource groups. If the signaling of the bit is newly set for all of the DCI formats carried over, then Ν = ? then + 3 bits of signaling are newly set on the DCI format of all PDCCHs. In the uplink carrier 1, the downlink carrier is reserved! The uplink control channel resource corresponding to the CCE of the PDCCH on the downlink carrier 2, that is, the uplink control channel resource corresponding to the CCE of the PDCCH on the downlink carrier.

However, in the uplink carrier 1, the uplink control channel resources of the downlink carrier 3 and the downlink carrier 4 are not reserved, that is, there is no uplink control channel resource corresponding to the CCE of the PDCCH on the downlink carrier. Therefore, for the ACK/NACK response transmission of the downlink carrier 3 and the downlink carrier 4, it is necessary to use the resource number or the resource group number in the uplink technical channel resource set configured by the upper layer. For the next 201225713 line carrier 3, the base station uses the PDCCH of the downlink carrier 3 to inform the user which element of the set is used for the ACK/NACK information of the PDSCH carried by the terminal. If the signaling of the bit is newly set for the DCI format carried on all PDCCHs, when N=7, the identifier “0〇1” may be used to inform the user terminal that the ACK/NACK response of the PDSCH on the downlink carrier is used by the upper layer. The first channel resource or the resource group in the allocated resource set is used as a response channel for carrying the response information. Referring to FIG. 7 , a flow chart of the processing process of the base station end of the method for configuring the uplink control channel resource according to the present invention includes the following steps: 701. Assigning, by the upper layer RRC signaling, the user terminal to allocate an uplink control channel resource set, where the set has N>=1 elements, corresponding to N ACK/NACK responses to available channel resources or resource groups. The element can be shared by multiple user terminals, and the base station restricts the time-phase response of the user terminal using the same channel resource by scheduling, thereby avoiding the channel resource collision problem. The resource property in the uplink control channel resource set is semi-persistent scheduling. And the base station configures resources in the uplink control channel resource set by high layer signaling. Step 702 The ground station determines whether there is an uplink control channel secondary source of the PDCCH to be responded to on the downlink carrier on the uplink carrier that performs the ACK/NACK response, and sets an identifier in the PDCCH according to the determination result, where the identifier is used to display 15 201225713 user terminal Whether to use the channel resources in the uplink control channel resource set for ACK/NACK response, and the use of channel resource elements in the set, for example: Case 1: On the uplink carrier performing the ACK/NACK response, there is a downlink carrier to be acknowledged The uplink control channel resource corresponding to the CCE of the PDCCH on the PDCCH, the uplink control channel resource corresponding to the CCE of the PDCCH on the downlink carrier to be replied is reserved on the uplink carrier that performs the ACK/NACK response, and the base station uses the PDCCH to notify the user. The terminal does not use the resources in the uplink control channel resource set allocated by the upper layer as the response channel. The method for signaling the PDCCH signaling may be signaling for newly setting a bit in the DC I format carried on all PDCCHs, or may be Bit signaling is combined with other signaling in Rel-8's existing DCI format, even reusing existing DCs The signaling in the I format indicates the N + 1 state. If the signaling of the bit is newly set for the DCI format carried on all PDCCHs, the bit can be set to all zeros, indicating that the resource set of the higher layer allocation is not used. In the case of the PDCCH/NACK response, there is no uplink control channel resource corresponding to the CCE of the PDCCH on the downlink carrier, that is, there is no uplink corresponding to the CCE of the PDCCH on the downlink carrier to be replied. Controlling channel resources. At this time, the base station selects an element in the set of uplink control channel resources allocated to the user as the response channel used for the ACK/NACK response, and uses the signaling of the PDCCH to indicate to the user terminal the resource element 16 201225713 Prime number. The method for signaling the PDCCH signaling may be signaling for newly setting a bit in the DC I format carried on all pj) CCHs, or in signaling in the existing DCI format of Re 1-8. Other signaling joint coding, even reusing the signaling in the existing DCI format to indicate the N+1 states "If the signaling for the newly set bit of the DCI format carried on all PDCCHs is used, the base station uses this meta indication When the selected channel resource element number (number starting from 1) or resource group number, for example, N = 7, the identifier '' 〇〇j,, • can be used to inform the user terminal of the PDSCH ACK/NACK response on the downlink carrier. The first channel resource or the first resource group in the resource set allocated by the layer is used as the response channel for carrying the response information. Please refer to FIG. 8 , which is a flowchart of a terminal side processing process of a method for configuring an uplink control channel resource according to the present invention, which includes: Step 801: Read high-level configuration signaling, and obtain an uplink control channel that is available for ACK/瞧 response set in a base station. a set of resources; Step 802: Detecting a PDCCH to be responded to the downlink carrier, determining whether to make

It means that the resources allocated by the upper layer are needed. The user terminal judges the following two cases according to the detected 17 201225713 PDCCH: Case 1: The elements in the uplink control channel resource set are not used. At this time, the channel resource number or the resource group number used for the ACK/NACK response is obtained according to the indication of the CCE pre-agreed by the PDCCH on the downlink carrier to be responded; Case 2: The element in the uplink control channel resource set is used. At this time, according to the identifier set in the PDCCH, the corresponding channel resource number or resource group number used for the ACK/NACK response is obtained (the number is within the range of the uplink control channel resource set); Step 803: Receive the PDSCH, and obtain the ACK after decoding. NACK responds to the news. Step 804: Send the obtained ACK/NACK response information on the channel resource determined in step 802.
