For example, in the case of subframe allocation 2, the ratio of the number of uplink subframes to the number of downlink subframes is 1: 4. The problem of limited uplink capacity is obvious in a large-traffic scene. In order to provide frequency domain diversity, a Physical Uplink Control Channel (PUCCH) is sent in a frequency hopping manner at a boundary of a slot (slot), that is, the same terminal device (UE) needs to send a high frequency resource of one slot and a low frequency resource of another slot in two slots of the same subframe.

Detailed Description

The embodiments of the present application will be described below with reference to the drawings.

As shown in fig. 1, fig. 1 is a schematic architecture diagram of a communication system 100 according to an embodiment of the present disclosure. The communication system 100 may include a network device 110 and terminal devices 101 to 106. It should be understood that more or fewer network devices or terminal devices may be included in the communication system 100 to which the methods of the embodiments of the present application may be applied. The network device or the terminal device may be hardware, or may be functionally divided software, or a combination of the two. The network device and the terminal device can communicate through other devices or network elements. In the communication system 100, the network device 110 can transmit downlink data to the terminal devices 101 to 106. Of course, terminal apparatuses 101 to 106 may transmit uplink data to network apparatus 110. Terminal devices 101-106 may be cellular phones, smart phones, laptops, handheld communication devices, handheld computing devices, satellite radios, global positioning systems, Personal Digital Assistants (PDAs), and/or any other suitable device for communicating over wireless communication system 100, among others. The communication system 100 may employ a Public Land Mobile Network (PLMN), a device-to-device (D2D) network, a machine-to-machine (M2M) network, an internet of things (IoT), or other networks. The terminal devices 104 to 106 may form a communication system. In the communication system, the terminal device 105 may transmit downlink data to the terminal device 104 or the terminal device 106. The method in the embodiment of the present application can be applied to the communication system 100 shown in fig. 1.

As shown in fig. 2, fig. 2 is a schematic diagram of an uplink channel bandwidth provided in an embodiment of the present application. The time domain resource comprises a subframe, and the subframe is divided into two time slots. The frequency domain resource is divided into two parts, the PUCCH channel is positioned at two sides of the uplink channel bandwidth, and the PUSCH channel is positioned at the middle continuous bandwidth. The PUSCH channel is used to transmit uplink data information, the PUCCH channel is used to transmit uplink control information sent by the UE, and the uplink control information may include a Scheduling Request Indication (SRI), a hybrid automatic repeat request (HARQ) acknowledgement/negative Acknowledgement (ACK)/(negative acknowledgement, NACK), and Channel State Information (CSI), where the ACK/NACK is used to feed back acknowledgement information for received downlink data, the SRI is used for the UE to request the base station to allocate PUSCH channel resources, and the CSI may include information such as a Channel Quality Indication (CQI). This ensures continuous single carrier characteristics for uplink transmission.

For example, as shown in fig. 3, fig. 3 is a schematic diagram of time-frequency positions and sizes occupied by control information transmitted on a PUCCH channel according to an embodiment of the present application. The outermost end of the frequency domain is the CQI part, followed by semi-static ACK/NACK and SRI, and the innermost is the dynamic ACK/NACK. Numbers 0-5 respectively represent 6 different UEs, wherein when UE 0 and UE 1 send CQI on the subframe, UE 0 occupies a low-frequency position and UE 1 occupies a high-frequency position on slot 0; conversely, on slot1, UE 0 occupies the high frequency location and UE 1 occupies the low frequency location. In this way, frequency hopping between two slots is achieved for both UE 0 and UE 1. When UE 2 and UE 3 send SRI on the subframe, UE 4 and UE 5 need to send dynamic ACK/NACK in the subframe, and their frequency hopping modes between two slots are the same as those of UE 0 and UE 1, which is not described herein again.

The CQI and SRI resource position of each UE is configured by high-level signaling, and the total frequency domain resource RB number occupied by the cell CQI and the SRI is related to the number of cell access users. As the number of users increases, the number of RBs to be allocated also increases. For dynamic ACK/NACK, the ACK/NACK channel index occupied by each UE is related to the PDCCH starting CCE position dynamically scheduled by a user, and the total RB size occupied by the cell dynamic ACK is determined by the total number of CCE of the cell PDCCH and delta PUCCH-shift configured by a high layer.

For example, for a TDD network with a 20M bandwidth and a subframe configuration of 2, a Control Format Indicator (CFI) is configured to be 3, a PUCCH cyclic shift interval (delta PUCCH-shift) is configured to be 1, the total number of CCEs of one HARQ feedback window (corresponding to 4 downlink scheduling subframes) is 315 (the 4 subframes respectively include 88, 84, 55, and 88 CCEs), one resource block (resource block, RB) has 36 PUCCH resources, the RB number occupied by the dynamic ACK is 315/36/delta PUCCH-shift is 8.75, and then the whole is rounded up to 9 RBs.

The CFI is configured to indicate, on a Physical Control Format Indicator Channel (PCFICH), an Orthogonal Frequency Division Multiplexing (OFDM) symbol (symbol) number occupied by a control region. The CFI value range is 1-3, and for a scene with a downlink system bandwidth larger than 10M, the number of OFDM symbols occupied by the control area is 1(CFI is 1), 2(CFI is 2) or 3(CFI is 3); for a scenario where the downlink system bandwidth is less than 10M, the number of OFDM symbols occupied by the control region is 2(CFI ═ 1), 3(CFI ═ 2), or 4(CFI ═ 3). The value range of Delta PUCCH-shift is 1-3. For the LTE system, one RB is divided into 12 subcarriers, and there are at most 12 cyclic shift values corresponding to the frequency domain sequence. If delta PUCCH-shift is 1, it means that the adjacent cyclic shift interval is 1, and the corresponding available cyclic shift number is 12. If delta PUCCH-shift is 2, it indicates that the adjacent cyclic shift interval is 2, and the corresponding available cyclic shift number is 6 (12/2). If delta PUCCH-shift is 3, it indicates that the adjacent cyclic shift interval is 3, and the corresponding available cyclic shift number is 4 (12/3).

In a normal (normal) cyclic prefix configuration, one slot contains 7 OFDM symbols; in an extended (extended) cyclic prefix configuration, one slot contains 6 OFDM symbols. The CQI is 20 bits after the physical layer coding is completed, and is adjusted into 10 constellation point symbols through Quadrature Phase Shift Keying (QPSK), and each constellation point symbol is mapped onto one OFDM symbol, so that one slot cannot carry 10 constellation point symbols, and finally the CQI carries different constellation point symbols on high and low frequency resources corresponding to two slots of one subframe. And the SRI and the ACK are adjusted into 1 constellation point symbol by Binary Phase Shift Keying (BPSK) (corresponding to 1bit ACK) or QPSK (corresponding to 2bit ACK), and can be copied on two slots, so that the symbols are mapped to all non-pilot OFDM symbols of 1 subframe, and therefore, the SRI and the ACK information carry the same constellation point symbol on the high frequency resource and the low frequency resource corresponding to two slots of one subframe.

In summary, PUCCH is sent in slot (slot) boundary frequency hopping, that is, the same UE needs to send in one high frequency resource of two slots of the same subframe and in another low frequency resource of the two slots. With the increase of the number of network users, the resource overhead of the PUCCH channel is increased, the PUSCH resource is continuously compressed, and the uplink capacity of the LTE system is low.

In order to save the available resources of the PUSCH channel, the UE may determine the allocated PUCCH resource in the dynamic PUCCH resource region in a frequency hopping manner by using a frequency hopping pattern agreed in advance with the network device according to the PUCCH resource start position notified by the network device and the size of the dynamic PUCCH resource region. Therefore, the ACK resource of the UE does not depend on the CCE initial position of the PDCCH any more, and the total RB number occupied by the dynamic ACK is reduced under the condition that the number of the users of the cell dynamic scheduling is small. However, this solution has the following problems: firstly, the network device needs to design a new algorithm to determine the PUCCH resource start position and the frequency hopping pattern of each UE, so as to ensure that the ACK resource positions of each UE are different, and the requirements on algorithm integrity and reliability are high. Second, the frequency hopping pattern needs to be agreed by the network device and the UE, and the frequency hopping pattern needs to be generated based on a pseudo-random sequence determined by one or more parameters of the UE, which increases the algorithm complexity of the UE. Thirdly, under the condition that the network is busy, the number of users in cell dynamic scheduling is large, and the resources occupied by dynamic ACK can not be reduced. In order to solve the above technical problem, embodiments of the present application provide the following solutions.

As shown in fig. 4, fig. 4 is a schematic flowchart of a communication method provided in the embodiment of the present application, where the steps in the embodiment of the present application at least include:

s401, a network device sends configuration indication information to a terminal device, the terminal device receives the configuration indication information sent by the network device, the configuration indication information is used for indicating an information sending mode among a plurality of subframes, each subframe of the plurality of subframes comprises high-frequency resources and low-frequency resources, and the plurality of subframes comprises a first subframe and a second subframe.

The embodiment of the application is applied to the scenes of non-dense network distribution and weak inter-cell interference, and the network equipment can send the configuration indication information to the terminal equipment through the system message or send the configuration indication information to the terminal equipment through high-level signaling configuration. Thereby ensuring information reliability.

S402, the terminal equipment sends at least one of acknowledgement information ACK and scheduling request indication SRI on the high-frequency resource of the first subframe according to the configuration information, and sends at least one of ACK and SRI on the low-frequency resource of the second subframe. The network equipment receives at least one of acknowledgement information ACK and Scheduling Request Indication (SRI) sent by the terminal equipment on the high-frequency resources of the first subframe, and receives at least one of ACK and SRI sent by the terminal equipment on the low-frequency resources of the second subframe.

In a specific implementation, the first subframe and the second subframe may be located in the same period of 10 ms. Alternatively, the first subframe may be located within 10ms of one period, and the second subframe may be located within 10ms of another period. The terminal device may send the ACK or SRI on the high frequency resources of slot0 of the first subframe and the ACK or SRI on the low frequency resources of slot0 of the second subframe. Alternatively, the terminal device may send the ACK or SRI on the high frequency resources of slot0 of the first subframe and the ACK or SRI on the low frequency resources of slot1 of the second subframe. Alternatively, the terminal device may send the ACK or SRI on the high frequency resources of slot1 of the first subframe and the ACK or SRI on the low frequency resources of slot0 of the second subframe. Alternatively, the terminal device may send the ACK or SRI on the high frequency resources of slot1 of the first subframe and the ACK or SRI on the low frequency resources of slot1 of the second subframe. The embodiments of the present application are not limited.

For example, as shown in fig. 5, fig. 5 is a schematic diagram of inter-frame frequency hopping provided in the embodiment of the present application. For a TDD network with a subframe ratio of 2, 10ms includes two uplink subframes, subframe 2 and subframe 7, and the other subframes in 10ms are downlink subframes. The UE and the network device may agree that the UE sends the SRI and the ACK on the low frequency resource of subframe 2, and the network device may receive the SRI and the ACK sent by the UE on the low frequency resource of subframe 2. Specifically, UE 2 only sends SRI in slot0 of subframe 2, UE 3 only sends SRI in slot1 of subframe 2, UE 4 only sends dynamic ACK in slot0 of subframe 2, and UE 5 only sends dynamic ACK in slot1 of subframe 2, so that all UEs only send SRI and dynamic ACK in low-frequency resources of subframe 2, and thus high-frequency resources of subframe 2 can be saved from being allocated to a PUSCH channel for UE to send service data to a network device.

As another example, as shown in fig. 6, fig. 6 is a schematic diagram of another inter-frame frequency hopping provided in this embodiment of the present application. The UE and the network device may agree that the UE sends the SRI and the ACK on the high frequency resource of the subframe 7, and the network device may receive the SRI and the ACK sent by the UE on the high frequency resource of the subframe 7. Specifically, UE 2 only sends SRI in slot1, UE 3 only sends SRI in slot0, UE 4 only sends dynamic ACK in slot1, and UE 5 only sends dynamic ACK in slot0, so that UE only sends SRI and dynamic ACK in the high frequency resource of subframe 7, thereby saving the allocation of the low frequency resource of subframe 7 to the PUSCH channel for UE to send service data to the network device. Therefore, half of the frequency band resources originally used for sending the SRI and the ACK in the subframe 2 and the subframe 7 can be saved for transmission of a PUSCH channel, and meanwhile, the diversity gain obtained by frequency hopping of users between different subframes is also ensured.

Optionally, the configuration indication information may include a frequency hopping period, where the frequency hopping period is used to indicate a separation distance between the first subframe and the second subframe. Since the UE sends the SRI to the network device only in the case of no PUSCH channel resource, the shortest period may be 5ms, and the longest period may be 80 ms. The dynamic ACK is determined by the downlink traffic of the network device and the PDSCH channel resources, and the terminal device may need to send the dynamic ACK in each uplink subframe. Therefore, the frequency hopping period of the SRI of the same UE can be designed to be longer according to the actual SRI transmission period. For example, for a UE with a period of 20ms, the SRI may be sent on the low frequency resource of the current periodic location and again on the high frequency resource of the periodic location after an interval of 20 ms. For the dynamic ACK, the dynamic ACK may be sent on two adjacent uplink subframes, the dynamic ACK may be sent on a low-frequency resource of one subframe, and the dynamic ACK may be sent on a high-frequency resource of another subframe.

Optionally, the configuration indication information may include a network type, and the network type is used for the terminal device to determine the separation distance between the first subframe and the second subframe. For a TDD network, if four uplink subframes, subframe 2, subframe 3, subframe 7, and subframe 8, are included within 10ms, the distance between the first subframe and the second subframe may be chosen in many ways. For example, the UE may choose to send SRI and dynamic ACK on the low frequency resources of subframe 2 and SRI and dynamic ACK on the high frequency resources of subframe 3. Or, the UE selects to send the SRI and the dynamic ACK on the low frequency resource of subframe 2 and send the SRI and the dynamic ACK on the high frequency resource of subframe 8. The UE may select different separation distances to send SRI and dynamic ACK, which are not illustrated. For an FDD network, an uplink channel and a downlink channel use different frequency bands, and each subframe can be used for uplink transmission, so that a frequency hopping mode between subframes can be designed more flexibly. For example, the SRI and the dynamic ACK are sent only on the low frequency resources of the odd subframes, and the SRI and the dynamic ACK are sent only on the high frequency resources of the even subframes, which are not illustrated.

Optionally, the network device may send a broadcast message to the terminal device, after receiving the broadcast message of the network device, the terminal device determines whether the terminal device supports a frequency hopping sending method among multiple subframes, and then sends a reply message to the network device, where the reply message may be UE capability information, and the reply message is used to determine whether the terminal device supports the frequency hopping sending method among the multiple subframes, and after receiving the reply message sent by the terminal device, if it is determined that the terminal device supports the frequency hopping sending method among the multiple subframes, the network device sends configuration indication information to the terminal device, where the configuration indication information is used to indicate that the terminal device adopts the technique of the scheme, that is, the frequency hopping sending method among the multiple subframes. If it is determined that the terminal device does not support a frequency hopping transmission mode between a plurality of subframes, the network device may not transmit the configuration indication information, and the terminal device still uses the original standard protocol technology, that is, a frequency hopping transmission mode between two slots. Under the condition that the terminal device is determined not to support the frequency hopping transmission mode among the plurality of subframes, the network device can also transmit other indication information to the terminal device, wherein the other indication information is used for indicating that the terminal device still adopts the original standard protocol technology. Thereby ensuring compatibility. The network device and the terminal device may negotiate through user-level signaling interaction.

For a terminal device supporting a frequency hopping transmission scheme among a plurality of subframes, the network device may adopt inter-subframe frequency hopping with a long interval distance, for example, frequency hopping once with an interval of 10ms, 20ms, and the like, when designing a frequency hopping period. For a terminal device that does not support a frequency hopping transmission mode among multiple subframes, the network device may allocate the time domain position of the SRI to the non-frequency hopping subframe for transmission when allocating the SRI resource to the terminal device, and also need to ensure that the dynamic ACK feedback is transmitted only on the non-frequency hopping subframe when performing downlink dynamic scheduling.

For example, as shown in fig. 7, fig. 7 is a schematic diagram of resource allocation provided in an embodiment of the present application. The subframe ratio is 2, the TDD network comprises two uplink subframes of a subframe 2 and a subframe 7 within 10ms, and the other 8 subframes within 10ms are downlink subframes. Fig. 7 shows a total of 4 radio frames including the 0 th frame, the 1 st frame, the 2 nd frame and the 3 rd frame. UE A and UE B are UEs which adopt an interframe frequency hopping sending mode, and UE C and UE D are UEs which use a standard protocol technology. UE A sends SRI and dynamic ACK on the low frequency resource of subframe 2 of frame 0 and sends SRI and dynamic ACK on the high frequency resource of subframe 2 of frame 2. UE B sends SRI and dynamic ACK on the low frequency of subframe 7 of frame 0 and sends SRI and dynamic ACK on the high frequency resource of subframe 7 of frame 2. UE C and UE D may send SRI and dynamic ACK simultaneously on the high frequency resources and the low frequency resources of the two uplink subframes of frame 1 and frame 3.

In the embodiment of the application, SRI and ACK are modified from inter-slot frequency hopping transmission to inter-subframe frequency hopping transmission in a subframe, so that the resource overhead of a PUCCH channel is effectively reduced, and the uplink capacity of an LTE system is improved.
