- FIG. 3 is a schematic diagram of the HARQ-ACK feedback corresponding to two downlink (DL, Down Link) data transmissions corresponding to one uplink control channel in this embodiment.
- the downlink data in the downlink slot #n and the downlink data in the downlink slot #(n+1) correspond to the short physical uplink control channel (PUCCH, in slot #(n+1),
- PUCCH physical uplink control channel
- Each 1-bit HARQ-ACK is fed back at the Physical Uplink Control Channel).
- the channel resource used by the user may be inconsistent with the understanding of the base station.
- the base station will determine '00' or '10', where the first bit corresponds to the downlink data on slot #n, and the second bit corresponds to the downlink data on slot # (n+1), so the base station will Triggering the retransmission of the downlink data on slot #(n+1).
- the base station will determine ⁇ x0, x2 ⁇ as '0' or '1', respectively.
- the base station user only detects the downlink data on slot #(n+1)
- the user can select a resource from ⁇ x0, x1 ⁇ to transmit, even if the base station sends data to the user in slot#n.
- the base station can also identify this situation if it is missed by the user. If the user detects data transmission at both slot#n and slot#(n+1), the user can select a resource from the used resources ⁇ x0, x1, x2, x3 ⁇ for transmission.
- the four sequence resources are time-domain cyclic shift values ⁇ 0, 3, 9, 6 ⁇ or ⁇ 1, 4, 10, 7 ⁇ or ⁇ 2, 5, 11, 8 ⁇ of the sequence, respectively.
- the cyclic shift value of the time domain is equal to the rotation value of the phase.
- the base station is required to configure the initial values of the sequence resources of the two slots to be the same, as in the above example, x0. and whether the data is sent in slot#n and slot#(n+1), the user is configured with 4 resources or Define users to get four resources.
- the above method configures a fixed-size feedback codebook for the network.
- the user always follows the 2-bit HARQ-ACK feedback, and once the control channel of a certain slot is missed, it is treated as NACK.
- Another solution is that the sequence resources allocated by the base station to the two slots are different, and the base station judges the user's transmission information through more blind detection.
- the resource overhead is large, and the blind detection of the base station is introduced, resulting in complexity. Increased performance and performance.
- the network configuration user When the network configuration user sends a 1- to 2-bit ACK/NACK message using the short PUCCH, it will be sent in the sequence selection mode. In this case, the base station needs to be configured to give the user 2 or 4 sequences. In order to implement the multiplexing of the SR and the ACK/NACK message, two or four SR resources need to be configured. When the SR and the ACK/NACK message are simultaneously sent, the configured SR resource is used to send the ACK/NACK message.
- the present embodiment indicates that the network can use RRC signaling to configure the SR with a default channel resource, where the resource mainly includes a starting symbol index, a number of symbols included in the control channel, a starting RB index, and an RB number ( The default can be 1), frequency hopping enable, initial cyclic shift index and other resource elements.
- the network can use RRC signaling to configure the SR with a default channel resource, where the resource mainly includes a starting symbol index, a number of symbols included in the control channel, a starting RB index, and an RB number ( The default can be 1), frequency hopping enable, initial cyclic shift index and other resource elements.
- the user obtains the first channel resource set according to a rule defined by the network. That is, the initial CS index is first randomized to obtain a sequence index (a first channel resource value), and then a sequence index set is obtained, which includes 2 or 4 sequence indexes, and the randomization method adopted for the SR at this time.
- the first and second implicit methods are the same as those used for ACK/NACK, and methods similar to those in Embodiments 1 and 2 can be employed.
- the user terminal may send an ACK/NACK message on the defined SR resource.
- the user terminal only uses the cyclic shift index of the SR, and the remaining channel resource elements associated with the short PUCCH are configured to allocate resource elements for ACK/NACK, such as a start symbol index, a number of symbols included in the control channel, and an initial RB. Index, RB number (default can be 1), frequency hopping enable, etc. Since the resource element for transmitting the ACK/NACK can be dynamically changed, the method can more dynamically adjust the resource information for transmitting the SR and the ACK/ACK, such as the length of the PUCCH, to achieve the benefit of saving power or improving coverage.
- the embodiment indicates that the network can use RRC signaling to configure the SR with a default channel resource, where the resource mainly includes an initial slot index, and the start Symbol index, number of symbols included in the control channel, starting RB index, number of RBs (default 1), frequency hopping enable, cyclic shift (CS) index, orthogonal mask (OCC) index, etc. Resource element.

- OCC orthogonal mask
- the network also configures a long PUCCH resource for the user to send a 1-2 bit ACK/NACK message, which contains the same resource element as the SR.
- the user terminal may send an ACK/NACK message on the defined SR resource.
- the user terminal only uses the cyclic shift index of the SR, the RB index and the start symbol index, and the remaining resource elements are the same as the resource elements configured to send the ACK/NACK, such as the number of symbols included in the control channel, frequency hopping enable, etc. . Since the resource element for transmitting the ACK/NACK can be dynamically changed, the method can more dynamically adjust the resource information for transmitting the SR and the ACK/ACK, such as the length of the PUCCH, to achieve the benefit of saving power or improving coverage.
- the user notifies the user of the behavior when transmitting the SR and the ACK/NACK simultaneously by using a 1-bit dynamic indication or an RRC configuration or an implicit indication. That is, it is determined whether all resource transmissions of the SR are used at this time, or only resources of part of the SR and resources of part of ACK/NACK are used for transmission.
- the user obtains two sequence resources from the network, respectively ⁇ x0, x2 ⁇ , which respectively correspond to the bit status '0', '1'. .
- the network sends data to the user at both slot#n and slot#(n+1), but the user only receives the data on slot#n, the user will select a resource from ⁇ x0,x2 ⁇ to send.
- the station will judge it as '00' or '10', that is, the missed detection can be judged as NACK at this time, and will not cause data loss.
- sequence resources ⁇ x0, x1, x2, x3 ⁇ respectively correspond to the sequence cyclic shift ⁇ 0, 3, 6, 9 ⁇ .
- the sequence resources used in slot #n in this embodiment are required to be identical to the sequence resources corresponding to the states '00', '10' at slot #(n+1).
- the network notifies the user by means of explicit indication of downlink control information or RRC configuration or implicit indication. If data transmission is detected only on slot #(n+1), the user always transmits according to 2-bit information, and assumes feedback on slot#n Always NACK. More generally, when the data transmission of the user at multiple times feeds back ACK/NACK on the same time-frequency resource, and the user only detects the data transmission at the last transmission time, the user assumes that all the previous time has data. Both are transmitted and treated as NACK.
- the method of the invention can realize flexible implementation of dynamic multiplexing of SR and ACK/NACK messages.
- the overhead of the uplink control information can be reduced while avoiding the blurring problem caused by the base station and the UE due to the loss of the downlink control channel.

- the transmitting end Due to the randomness of data arrival, when the data arrives at the sTTI without DM-RS, the transmitting end needs to delay for a period of time until the nearest sTTI of the DM-RS can be sent, which obviously increases the transmission delay of the data. Another possibility is that the transmitting end rolls back to send data according to the sTTI with DM-RS, so although the delay is not reduced, the receiving end needs to perform detection according to two possibilities, which increases the processing complexity.
- the transmitting end transmits data in the sTTI where the DM-RS is not configured
