Abstract: The embodiments of the present disclosure provide a method for sending and a method for receiving a HARQ codebook, an apparatus, and a storage medium. The method for sending a HARQ codebook comprises: determining the total quantity of candidate PDSCH receiving occasions on the basis of HARQ feedback time sets of a plurality of candidate services, and determining a codebook sequence corresponding to a candidate PDSCH receiving occasion in each time unit; determining the value of each bit in the HARQ codebook according to whether downlink data is correctly received at a receiving occasion of each candidate PDSCH; and sending the HARQ codebook. According to the method for sending and method for receiving a HARQ codebook, the apparatus, and the storage medium provided in the embodiments of the present disclosure, the total quantity of candidate PDSCH receiving occasions is determined on the basis of HARQ feedback time sets of a plurality of candidate services, so that the length of a generated HARQ codebook is shortened, thus improving resource utilization.

Abstract: The present application provides a semi-persistent scheduling method for a multicast/broadcast service, an apparatus and a storage medium. A network device configures semi-persistent configuration information for terminals in advance, and the semi-persistent configuration information includes a first identifier for scrambling activation information and related information of a PDSCH for sending a multicast/broadcast service. Every time multicast/broadcast service data transmission is required, the network device sends the activation information to terminal devices according to the first identifier to indicate activating the semi-persistent configuration information, and then sends the PDSCH to the terminal devices by multicast/broadcast according to the semi-persistent configuration information, thereby realizing that multicast/broadcast service data is transmitted from the network device to N terminal devices by multicast/broadcast. Since the semi-persistent configuration information is received by the terminal devices from the network device in advance and saved locally, and is activated by the activation information scrambled by the first identifier, there is no need to receive the semi-persistent configuration information from the network device every time the multicast/broadcast service data is transmitted, thereby saving air interface resources.

Abstract: Disclosed in the present disclosure are a data transmission time domain parameter indication method, a user equipment (UE), and a base station, comprising: indicating, by means of indication information carried in downlink control information (DCI), whether scheduling data of the UE comprises a beam switching time interval GAP, or making an agreement with the UE to determine, by means of a scheduling condition, whether the scheduling data comprises the GAP; when it is determined that the GAP is comprised, determining the GAP according to a UE switching capability parameter agreed upon by an interface protocol; and transmitting the scheduling data on a beam after the GAP. By using the method provided in the present disclosure, in high-frequency scheduling design, the effect on the protocol can be reduced, and the implementation complexity of the UE and the base station can be reduced.

Abstract: Provided in the embodiments of the present disclosure are a hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback method, a terminal, and a base station. The method comprises: receiving broadcast multicast scheduling signaling sent by a base station, and determining an uplink resource corresponding to unicast; and when it is detected that a preset condition is satisfied, multiplexing a first HARQ-ACK codebook corresponding to the broadcast multicast scheduling signaling onto the uplink resource corresponding to the unicast, wherein the preset condition is that a HARQ-ACK feedback time slot indicated by the broadcast multicast scheduling signaling and a time slot in which the uplink resource is located exist in a preset window at the same time. In the embodiments of the present disclosure, the design and complexity of a HARQ-ACK protocol for broadcast multicast feedback is simplified.

Abstract: The present disclosure provides a DAI in uplink indication method, a device and a storage medium. The number of DAI in uplink configured by a network device for broadcast multicast services is acquired; a corresponding relationship between a HARQ-ACK sub-codebook of each broadcast multicast service and each DAI in uplink is determined; a length of a corresponding HARQ-ACK sub-codebook is determined according to the corresponding relationship and scheduling signaling received from the network device for a broadcast multicast service. According to the embodiments of the present disclosure, there is no need to configure DAI in uplink according to the maximum number of broadcast multicast services or the maximum number of possibly generated HARQ-ACK sub-codebooks, but the purpose of determining the length of a HARKHARQ-ACK sub-codebook can still be achieved, thus scheduling flexibility of the network device can be improved, and signaling overheads of the DAI in uplink can be reduced.
