Abstract: Physical Uplink Control Channel (PUCCH) can be effectively allocated and utilized by base stations and mobile stations. In an exemplary embodiment, a mobile station receives from a base station an allocation of a first set channel resource groups. The base station assigns a second set of channel resource groups. The mobile station decodes, based on the second set of channel resource groups, one or more channel resources to transmit messages to the base station. A benefit of the disclosed exemplary embodiments is that a base station can dynamically assign channel resources to a mobile station.

Abstract: The present disclosure provides a method and an apparatus for information transmission. The method includes: transmitting information or a channel over one or more of available narrow bands. The available narrow bands include available uplink narrow bands and/or available downlink narrow bands and the available narrow bands are determined based on information including at least one of: a system bandwidth, a cell identity, a position of an anchor carrier, information indicated by a PSS, information indicated by an SSS, information indicated by a MIB and information indicated by a SIB. The information or channel transmitted over the one or more narrow bands includes at least one of: a downlink control channel, a PDSCH, an RAR, a paging message, a SIB, a MIB, a PRACH, a PUSCH, and a PUCCH. The above solution solves the problem regarding how to obtain multiple narrow bands/carriers in NB-IoT and provides a scheme for determining available narrow bands.

Abstract: Disclosed is a data transmission method and apparatus, and an electronic device. The method includes that a transmitting end transmits data over an allocated resource. The allocated resource includes one of: a first type of resource and a second type of resource; or the second type of resource. A starting time of the second type of resource is later than a starting time of the first type of resource, or an ending time of the second type of resource is earlier than an ending time of the first type of resource. The data transmitted over the first type of resource and the date transmitted over the second type of resource are aligned on a time-domain symbol.
