The following explains some concepts and/or terms involved in the feedback method and device provided in the embodiments of the present invention.

1. Business scenarios in new radio technology (new radio, NR)

In the standardization process of NR technology, three types of usage scenarios are mainly considered: enhanced mobile broadband (eMBB), massive machine type communications (mMTC), and ultra-reliable low-latency communications (ultra- reliable and low latency communications, URLLC). The three types of usage scenarios have large differences in performance requirements in terms of data rate, delay, reliability, number of connections, traffic density, and mobility. Among them, the eMBB scenario focuses on data rate and traffic density, the mMTC scenario focuses on the number of connections, and the URLLC scenario focuses on latency and reliability. These three types of usage scenarios are closely related to business attributes and bearer requirements, and they can be called business scenarios.

2. HARQ-ACK codebook

For the HARQ-ACK process supporting transport block level (TB-level), one HARQ-ACK bit can be fed back correspondingly to one TB. A TB can support a single downlink HARQ process of a UE, and can also support multiple downlink HARQ processes of a UE. For eMBB scenarios and URLLC scenarios, asynchronous downlink HARQ processes and adaptive downlink HARQ processes can be supported. From the perspective of the UE, HARQ-ACKs for multiple physical downlink control channels (PDCCH) can be transmitted in one uplink data/control area in time, and the UE can be in the uplink data/control area. The above constitutes a HARQ-ACK codebook. Generally, the network equipment needs to indicate the minimum HARQ processing time of the UE. The minimum HARQ processing time represents the minimum time required from the UE receiving downlink data to the timing of feeding back the corresponding HARQ-ACK. Generally, the network device can specify the timing between receiving the physical downlink shared channel (PDSCH) and feedback of the corresponding ACK/NACK in the DCI.

In the R15 protocol, the UE can support two types of HARQ-ACK codebooks, namely: semi-static HARQ-ACK codebook (semi-static HARQ-ACK codebook) and dynamic HARQ-ACK codebook (dynamic HARQ-ACK codebook) ). For the semi-static HARQ-ACK codebook, the UE can configure PDCCH monitoring accession (PDCCH monitoring accession), PDSCH-time domain resource allocation (PDSCH-time domain resource allocation), PDSCH configuration according to radio resource control (RRC) configuration Parameters such as HARQ-ACK feedback timing (dl-Data To UL-ACK or PDSCH-to HARQ-timing) are used to determine all PDSCHs that may be fed back in a certain time slot, and the HARQ-ACK codebook is determined. Since it may include PDSCH for actual scheduling and PDSCH for unscheduled, the semi-static HARQ-ACK codebook is generally larger. For the dynamic HARQ-ACK codebook, the UE determines the HARQ-ACK codebook according to the actually scheduled PDSCH. Since only the actually scheduled PDSCH is fed back, the size of the dynamic HARQ-ACK codebook is usually smaller than that of the semi-static HARQ-ACK codebook. Codebook size. Generally, which type of codebook the UE uses can be determined through RRC configuration.

3. One-shot HARQ-ACK codebook

In NR-U, in order to ensure that both the UE and the network equipment have the same understanding of the number of HARQ-ACK codebook bits, and that the UE can feed back the HARQ-ACK information of all the configured HARQ processes of the UE, one is introduced in the related technology. -shot HARQ-ACK codebook feedback mechanism, based on this feedback mechanism, the UE can feed back HARQ-ACK information for all possible codewords of all HARQ processes configured on all carriers currently configured for the UE. In order to ensure that the UE and network equipment (e.g., eNB) have consistent understanding of the PDSCH transmission corresponding to the HARQ-ACK bit fed back, and avoid the ambiguity of understanding caused by missed DCI detection, each can be fed back in the one-shot HARQ-ACK codebook. The new data indicator (NDI) of the codeword. If a codeword of a HARQ process has not been scheduled, the NDI corresponding to the codeword can be defined to be equal to 0. Among them, the network device can configure whether the NDI is included in the one-shot HARQ-ACK codebook.

4. Downlink assignment index (DAI)

The DCI used for downlink grants includes the DAI field, which can be used to indicate how much each configured serving cell (serving cell) has sent to the current subframe (the current subframe is in the HARQ feedback window) PDCCH with PDSCH transmission or how many PDCCHs indicating the release of downlink SPS, the value will be updated between each subframe. When HARQ-ACK information needs to be combined with other uplink control information (uplink control information, UCI) (such as channel state information (channel state information, CSI)) and UL-SCH is transmitted on PUSCH, network equipment and UE need to transmit on the uplink The understanding of how many bits of HARQ-ACK information and how many physical resources it occupies is consistent. It can be scheduled by network equipment, or the protocol can implicitly determine how many bits of HARQ-ACK information to transmit according to some rules. Based on this, the network equipment can correctly receive the UCI and/or uplink shared channel (UL-SCH) part of the PUSCH. In order to achieve the above purpose, when the network device performs uplink scheduling PUSCH transmission, it carries the Total DAI field in the DCI used for uplink grant, which is used to inform the UE of the number of HARQ-ACK bits in this transmission. .

The embodiment of the present invention provides a feedback method and device. The UE can be in a predefined position in the HARQ-ACK codebook, a position configured by a network device, a position corresponding to a process number, or a first determined position from the HARQ-ACK codebook. A reserved position to transmit feedback information for DCI, that is, the UE can determine the position in the HARQ-ACK codebook for the HARQ-ACK information for the DCI configured to release the SPS according to the above-mentioned multiple methods, so that the UE is in When sending feedback information to the network device, the HARQ-ACK codebook can be correctly constructed, so that based on the HARQ-ACK codebook, the UE can correctly feed back the HARQ-ACK information for the DCI.

The feedback method and device provided by the embodiment of the present invention can be applied to a communication system. It can be specifically applied to the process in which the UE sends feedback information to the network device based on the communication system.

The embodiments of the present invention can be applied to various communication systems, for example, 5G communication systems, future evolution systems, or other communication systems. It can include multiple application scenarios, such as machine-to-machine (M2M), D2M, enhanced mobile Internet (eMBB), and ultra-high reliability and ultra-low latency communication (uRLLC) scenarios. The details can be determined according to actual use requirements, and the embodiment of the present invention does not limit it.

Exemplarily, FIG. 1 shows a schematic diagram of the architecture of a communication system provided by an embodiment of the present invention. As shown in Figure 1, the communication system may include UE 01 and network equipment 02. Among them, a connection and communication can be established between the UE 01 and the network device 02.

A UE is a device that provides users with voice and/or data connectivity, a handheld device with wired/wireless connection functions, or other processing devices connected to a wireless modem. The UE may communicate with one or more core network devices through a radio access network (RAN). The UE can be a mobile terminal, such as a mobile phone (or called a "cellular" phone) and a computer with a mobile terminal. It can also be a portable, pocket-sized, handheld, built-in computer or vehicle-mounted mobile device, which exchanges languages with the RAN And/or data, for example, personal communication service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (personal digital assistants) , PDA) and other equipment. The UE may also be referred to as a user agent (User Agent) or terminal equipment. As an example, in the embodiment of the present invention, FIG. 1 shows that the UE is a mobile phone as an example.

The network device may be a base station. A base station is a device deployed in the RAN to provide wireless communication functions for the UE. The base station may include various forms of macro base stations, micro base stations, relay stations, access points, and so on. In systems using different wireless access technologies, the names of devices with base station functions may be different. For example, in the third-generation mobile communication (3G) network, they are called base stations (NodeB); in the long-term evolution ( In the long term evolution (LTE) system, it is called an evolved NodeB (eNB or eNodeB); in the fifth generation mobile communication (5G) network, it is called a gNB and so on. With the evolution of communication technology, the name "base station" may change.

In future communication systems, unlicensed bands can be used as a supplement to licensed bands to help operators expand services. In order to be consistent with NR deployment and maximize NR-based unlicensed access, unlicensed frequency bands can work in 5GHz, 37GHz and 60GHz frequency bands. The large bandwidth (80MHz or 100MHz) of the unlicensed frequency band can reduce the implementation complexity of the base station and UE. When the UE is working in an unlicensed frequency band and the UE is configured with at least one DL SPS configuration, the network device can release (or deactivate, release or deactivated) one or more DL SPS configurations that the UE has activated by sending DCI operate. When the UE detects the DCI for releasing the SPS, the UE feeds back the corresponding HARQ-ACK information on the corresponding uplink resource (usually PUCCH, the PUCCH resource is indicated by the SPS release DCI) for the DCI for releasing the SPS.
