Abstract: The present application relates to methods, systems, and devices related to digital wireless communication, and more specifically, to techniques related to determining PUCCH resources for a HARQ-ACK codebook of a MBMS service. In one exemplary aspect, a method for wireless communication is disclosed. The method includes receiving, by a terminal, a first set of information relating to a unicast service and a second set of information relating to a multimedia broadcast multicast service (MBMS). The method also includes generating, by the terminal, a final codebook that is a concatenation of a first codebook based on the first set of information and a second codebook based on the second set of information.

Abstract: In various arrangements, a User Equipment (UE) receives at least one of first scheduling indicators and second scheduling indicators. Each of the first scheduling indicators schedules a transmission. The transmission scheduled by each of the first scheduling indicators is a first transmission type or a second transmission type. Each of the second scheduling indicators schedules two or more of the transmissions. Each transmission scheduled by a second scheduling indicator is the first transmission type or the second transmission type. The UE generates one or more sub-codebooks according to one or more of the first scheduling indicators, the second scheduling indicators, the first transmission type, and the second transmission type. The UE generates a codebook by combining the generated one or more sub-codebooks.

Abstract: Method and apparatus for transmitting downlink control information (DCI) are provided. The method includes: scheduling traffic channels in multiple transmission time intervals (TTIs) through a single DCI, where a subcarrier spacing of a carrier where the scheduled traffic channel is located is not smaller than a subcarrier spacing of a carrier where the DCI scheduling the traffic channel is located; and transmitting the DCI. A problem of how to use a multi-TTI scheduling for a cross-carrier scheduling in which a subcarrier spacing of a scheduling carrier is smaller than a subcarrier spacing of a scheduled carrier in the related art may be solved, and the effects of scheduling the multiple TTIs through a single DCI and reducing the overhead are achieved.

Abstract: The present invention provides a method and apparatus for determining a scheduling gap, wherein, the method comprises: demodulating the NarrowBand Physical Downlink Control Channel in order to determine the initial subframe of the scheduled NarrowBand Physical Downlink Shared Channel (NB-PDSCH) or the NarrowBand Physical Uplink Shared Channel (NB-PUSCH), wherein, the basis for determining the initial subframe comprises at least one of the following: the final subframe of the NB-PDCCH, the final subframe in the search space where the NB-PDCCH is located, the resource allocation within the scheduling window, and the scheduling gap indication. The implementation of the present technical solutions solves the problem of how to determine the scheduling within the NarrowBand system, thereby saving indication expenditure and improving resource usage efficiency.
