In order to provide frequency domain diversity, the physical uplink control channel (PUCCH) hops and transmits at the boundary of the slot, that is, the same terminal equipment (UE) needs to be in two slots of the same subframe. The high-frequency resources of one slot and the low-frequency resources of the other slot are sent.

detailed description

The embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

As shown in FIG. 1, FIG. 1 is a schematic structural diagram of a communication system 100 provided by an embodiment of the present application. The communication system 100 may include a network device 110 and terminal devices 101 to 106. It should be understood that the communication system 100 to which the method in the embodiments of the present application can be applied may include more or fewer network devices or terminal devices. The network device or terminal device can be hardware, software that is functionally divided, or a combination of the two. The network device and the terminal device can communicate with other devices or network elements. In the communication system 100, the network device 110 can send downlink data to the terminal devices 101 to 106. Of course, the terminal device 101 to the terminal device 106 may also send uplink data to the network device 110. The terminal device 101 to the terminal device 106 may be cellular phones, smart phones, portable computers, handheld communication devices, handheld computing devices, satellite radio devices, global positioning systems, handheld computers (personal digital assistants, PDAs) and/or used in wireless Any other suitable devices for communication on the communication system 100, etc. The communication system 100 may adopt a public land mobile network (PLMN), a device-to-device (D2D) network, a machine-to-machine (M2M) network, and the Internet of things (Internet of things). , IoT) or other networks. In addition, the terminal device 104 to the terminal device 106 may also form a communication system. In this communication system, the terminal device 105 can send 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 by an embodiment of the present application. Among them, the time domain resource includes one subframe, and one subframe is divided into two time slots. The frequency domain resources are divided into two parts, the PUCCH channel is located on both sides of the uplink channel bandwidth, and the PUSCH channel is located in the continuous bandwidth in the middle. Among them, the PUSCH channel is used to transmit uplink data information, and the PUCCH channel is used to transmit uplink control information sent by the UE. The uplink control information may include scheduling request indication (SRI) and hybrid automatic repeat request. HARQ) acknowledgement/negative acknowledgement (acknowledgement, ACK)/(negative acknowledgement, NACK) and channel state information (channel state information, CSI), where ACK/NACK is used to feed back acknowledgement information to received downlink data, and SRI is used for UE The base station is requested to allocate PUSCH channel resources, and the CSI may include information such as channel quality indicator (CQI). In this way, the continuous single-carrier characteristics of uplink transmission can be guaranteed.

For example, as shown in FIG. 3, FIG. 3 is a schematic diagram of the time-frequency position and size occupied by each control information transmitted on the PUCCH channel provided by an embodiment of the present application. The outermost part of the frequency domain is the CQI part, then semi-static ACK/NACK and SRI, and the innermost part is dynamic ACK/NACK. The numbers 0 to 5 represent 6 different UEs respectively. Among them, when UE 0 and UE 1 send CQI on this subframe, on slot 0, UE 0 occupies the low frequency position, and UE 1 occupies the high frequency position; on the contrary, in slot 1 Above, UE 0 occupies the high frequency position, and UE 1 occupies the low frequency position. In this way, the frequency hopping between the two slots is implemented for both UE 0 and UE 1. When UE 2 and UE 3 send SRI in this subframe, UE 4 and UE 5 need to send dynamic ACK/NACK in this subframe. The frequency hopping between the two slots is the same as that of UE 0 and UE 1. I won't repeat it here.

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

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

Among them, the CFI is used to indicate the number of orthogonal frequency division multiplexing (OFDM) symbols (OFDM) occupied by the control area on the physical control format indicator channel (PCFICH). The value of CFI ranges from 1 to 3. For scenarios where the downlink system bandwidth is greater than 10M, the number of OFDM Symbols occupied by the control area is 1 (CFI=1), 2 (CFI=2) or 3 (CFI=3); for downlink When the system bandwidth is less than 10M, the number of OFDM symbols occupied by the control area is 2 (CFI=1), 3 (CFI=2), or 4 (CFI=3). The value range of Delta PUCCH-shift is 1 to 3. For the LTE system, one RB is divided into 12 subcarriers, and the corresponding frequency domain sequence has a maximum of 12 cyclic shift values. If delta PUCCH-shift=1, it means that the adjacent cyclic shift interval is 1, and the corresponding number of available cyclic shifts is 12. If delta PUCCH-shift=2, it means that the adjacent cyclic shift interval is 2, and the corresponding available cyclic shift number is 6 (12/2). If delta PUCCH-shift=3, it means that the adjacent cyclic shift interval is 3, and the corresponding available cyclic shift number is 4 (12/3).

In a normal cyclic prefix configuration, a slot contains 7 OFDM symbols; in an extended cyclic prefix configuration, a slot contains 6 OFDM symbols. CQI is 20bit after physical layer coding, and adjusted to 10 constellation point symbols through quadrature phase shift keying (QPSK). Each constellation point symbol is mapped to an OFDM symbol, so one slot cannot carry it. 10 constellation point symbols, and finally CQI carries different constellation point symbols on the high and low frequency resources corresponding to two slots in a subframe. The SRI and ACK are adjusted to 1 constellation point symbol after binary phase shift keying (BPSK) (corresponding to 1bit ACK) or QPSK (corresponding to 2bit ACK), which can be copied on two slots, so Mapped to all non-pilot OFDM symbols in a subframe, therefore, SRI and ACK information carry the same constellation point symbols on the high-frequency resources and low-frequency resources corresponding to two slots in one subframe.

In summary, the PUCCH is sent by frequency hopping at the boundary of a slot, that is, the same UE needs to be sent in the high-frequency resource of one slot and the low-frequency resource of the other slot in the two slots of the same subframe. As the number of network users increases, the resource overhead of the PUCCH channel increases, which causes the PUSCH resources to be 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 can adopt the frequency hopping pattern agreed with the network equipment in advance according to the starting position of the PUCCH resource and the size of the dynamic PUCCH resource area notified by the network equipment, and determine by frequency hopping in the dynamic PUCCH resource area PUCCH resources allocated. In this way, the ACK resource of the UE no longer depends on the CCE starting position of the PDCCH, and the total number of RBs occupied by the dynamic ACK is reduced when the number of dynamically scheduled users in the cell is small. However, this technical solution has the following problems: First, the network equipment needs to design a new algorithm to determine the PUCCH resource starting position and frequency hopping pattern of each UE, to ensure that the ACK resource position of each UE is different, and the algorithm is complete. And high reliability requirements. Second, the frequency hopping pattern needs to be agreed between the network equipment 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 complexity of the UE's algorithm. Third, when the network is busy, there are many users dynamically scheduled in the cell, and the resources occupied by the dynamic ACK can not be reduced. In order to solve the above technical problems, the 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 by an embodiment of the present application. The steps in the embodiment of the present application at least include:

S401: The network device sends configuration indication information to the terminal device, and the terminal device receives the configuration indication information sent by the network device, where the configuration indication information is used to indicate a manner of sending information between multiple subframes, and each of the multiple subframes The subframes include high-frequency resources and low-frequency resources, and the multiple subframes include a first subframe and a second subframe.

Among them, the embodiments of the present application are applied in a scenario where a non-dense network is distributed and inter-cell interference is not strong. The network device can send configuration indication information to the terminal device through system messages, or send configuration indication information to the terminal device through high-level signaling configuration. So as to ensure the reliability of information.

S402: According to the configuration information, the terminal device sends at least one of acknowledgment information ACK and scheduling request indication SRI on the high-frequency resource in the first subframe, and in the low-frequency resource of the second subframe. Sending at least one of the ACK and the SRI on the resource. The network device receives at least one of the confirmation information ACK and the scheduling request indication SRI sent by the terminal device on the high-frequency resource of the first subframe, and on the low-frequency resource of the second subframe Receiving at least one of the ACK and the SRI sent by the terminal device.

In 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 in one period of 10ms, and the second subframe may be located in another period of 10ms. The terminal device may send ACK or SRI on the high frequency resource of slot 0 in the first subframe, and send ACK or SRI on the low frequency resource of slot 0 in the second subframe. Alternatively, the terminal device may send the ACK or SRI on the high frequency resource of slot 0 in the first subframe, and send the ACK or SRI on the low frequency resource of slot 1 in the second subframe. Alternatively, the terminal device may send the ACK or SRI on the high frequency resource of slot 1 in the first subframe, and send the ACK or SRI on the low frequency resource of slot 0 in the second subframe. Alternatively, the terminal device may send the ACK or SRI on the high frequency resource of slot 1 in the first subframe, and send the ACK or SRI on the low frequency resource of slot 1 in 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 an inter-frame frequency hopping provided by an embodiment of the present application. For a TDD network with a subframe ratio of 2, two uplink subframes, subframe 2 and subframe 7, are included within 10ms, and the other subframes within 10ms are downlink subframes. The UE and the network equipment may agree that the UE sends SRI and ACK on the low-frequency resource of subframe 2, and the network equipment may receive the SRI and ACK sent by the UE on the low-frequency resource of subframe 2. Specifically, UE 2 sends SRI only in slot 0 of subframe 2, UE 3 sends SRI only in slot 1 of subframe 2, UE 4 sends dynamic ACK only in slot 0 of subframe 2, and UE 5 sends SRI only in slot 1 of subframe 2. Dynamic ACK, so that all UEs only send SRI and dynamic ACK on the low frequency resources of subframe 2, so that the high frequency resources of subframe 2 can be saved and allocated to the PUSCH channel for use by the UE to send service data to the network device.

As another example, as shown in FIG. 6, FIG. 6 is a schematic diagram of another inter-frame frequency hopping provided by an embodiment of the present application. The UE and the network device may agree that the UE sends the SRI and ACK on the high-frequency resource of the subframe 7, and the network device may receive the SRI and ACK sent by the UE on the high-frequency resource of the subframe 7. Specifically, UE 2 only sends SRI on slot 1, UE 3 only sends SRI on slot 0, UE 4 only sends dynamic ACK on slot 1, and UE 5 only sends dynamic ACK on slot 0. In this way, UE only sends SRI on subframe 7. The SRI and dynamic ACK are sent on the high-frequency resources, so that the low-frequency resources of the subframe 7 can be saved and allocated to the PUSCH channel for use by the UE to send service data to the network device. Therefore, one-half of the frequency band resources originally used to send SRI and ACK in subframe 2 and subframe 7 can be saved for PUSCH channel transmission, and it is also ensured that users can hop between different subframes. Obtain diversity gain.

Optionally, the configuration indication information may include a frequency hopping period, and the frequency hopping period is used to indicate the separation distance between the first subframe and the second subframe. Since the UE sends the SRI to the network device only when there is no PUSCH channel resource, the shortest period can be 5 ms, and the longest period can be 80 ms. The dynamic ACK is determined by the downlink service of the network equipment and the PDSCH channel resources, and the terminal equipment may need to send the dynamic ACK in every 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 20 ms, the SRI may be sent on the low-frequency resource at the current periodic position, and the SRI may be sent again on the high-frequency resource at the periodic position after an interval of 20 ms. For dynamic ACK, dynamic ACK can be sent on two adjacent uplink subframes, dynamic ACK can be sent on the low frequency resource of one of the subframes, and dynamic ACK can be sent on the high frequency resource of the other subframe.

Optionally, the configuration indication information may include a network type, and the network type is used by the terminal device to determine the separation distance between the first subframe and the second subframe. For a TDD network, if there are four uplink subframes including subframe 2, subframe 3, subframe 7, and subframe 8 within 10ms, there are multiple choices for the separation distance between the first subframe and the second subframe. For example, the UE may choose to send SRI and dynamic ACK on the low frequency resource of subframe 2, and send SRI and dynamic ACK on the high frequency resource of subframe 3. Or, the UE chooses to send SRI and dynamic ACK on the low frequency resource of subframe 2, and sends SRI and dynamic ACK on the high frequency resource of subframe 8. The UE can select different separation distances to send SRI and dynamic ACK, and the others will not be illustrated one by one. For FDD networks, the uplink channel and the downlink channel use different frequency bands, and each subframe can be used for uplink transmission, so the inter-subframe frequency hopping method can be designed more flexibly. For example, only the SRI and dynamic ACK are sent on the low-frequency resources of the odd-numbered subframes, and the SRI and dynamic ACK scores are only sent on the high-frequency resources of the even-numbered subframes. Other examples will not be illustrated one by one.

Optionally, the network device may send a broadcast message to the terminal device. After receiving the broadcast message from the network device, the terminal device determines whether to support the frequency hopping transmission mode between multiple subframes, and then sends a reply message to the network device, the reply message It can be UE capability information. The reply message is used to determine whether the terminal device supports the frequency hopping transmission mode between multiple subframes. After the network device receives the reply message sent by the terminal device, if it is determined that the terminal device supports the transmission between multiple subframes In the frequency hopping transmission mode, the network device sends configuration indication information to the terminal device. The configuration indication information is used to instruct the terminal device to use the technology of this solution, that is, the frequency hopping transmission mode between multiple subframes is adopted. If it is determined that the terminal equipment does not support the frequency hopping transmission mode between multiple subframes, the network equipment does not need to send the configuration instruction information, and the terminal equipment still uses the original standard protocol technology, that is, the frequency hopping transmission mode between two slots is adopted. When it is determined that the terminal device does not support the frequency hopping transmission mode between multiple subframes, the network device may also send other indication information to the terminal device, and the other indication information is used to instruct the terminal device to still use the original standard protocol technology. So as to ensure compatibility. Among them, the network device and the terminal device can negotiate through user-level signaling interaction.

For terminal devices that support a frequency hopping transmission mode between multiple subframes, the network device can use a longer interval of frequency hopping between subframes when designing a frequency hopping cycle, for example, a frequency hopping interval of 10ms, 20ms, etc. once. For terminal equipment that does not support frequency hopping transmission between multiple subframes, the network equipment may allocate SRI resources to the terminal equipment by assigning the time domain position of the SRI to non-frequency hopping subframes for transmission. In downlink dynamic scheduling, it is also necessary to ensure that dynamic ACK feedback is only transmitted on non-frequency hopping subframes.

For example, as shown in FIG. 7, FIG. 7 is a schematic diagram of resource allocation provided by an embodiment of the present application. A TDD network with a subframe ratio of 2, includes two uplink subframes, subframe 2 and subframe 7, within 10ms, and the other 8 subframes within 10ms are downlink subframes. As shown in Fig. 7, there are a total of 4 radio frames, including frame 0, frame 1, frame 2, and frame 3. UE A and UE B are UEs that use the inter-frame frequency hopping transmission mode, and UE C and UE D are UEs that use standard protocol technology. UE A sends SRI and dynamic ACK on the low frequency resource of subframe 2 in the 0th frame, and sends the SRI and dynamic ACK on the high frequency resource of subframe 2 in the 2nd frame. UE B sends SRI and dynamic ACK in the low frequency of subframe 7 of the 0th frame, and sends the SRI and dynamic ACK on the high frequency resource of subframe 7 of the 2nd frame. UE C and UE D may simultaneously send SRI and dynamic ACK on the high-frequency resources and low-frequency resources of the two uplink subframes of the first frame and the third frame.

In the embodiments of the present application, by modifying SRI and ACK from inter-slot frequency hopping transmission in subframes to inter-subframe frequency hopping transmission, the resource overhead of the PUCCH channel is effectively reduced, and the uplink capacity of the LTE system is improved.
