Abstract: In a transmitting device, each of the plurality of mapping candidates that make up the search space is configured from the same number of control channel elements as an aggregation level value, the control channel elements are obtained by dividing each physical resource block into a predetermined number, and the quantity of resource elements contained in each of the predetermined number of control channel elements in each physical resource block adopts at least two types of values. A search space setting unit (102) sets a search space of which the aggregation level value is 2 or more so that, between a plurality of mapping candidates, variation in the total quantity of resource elements contained in the control channel elements that make up the mapping candidates is as small as possible.

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: Embodiments of the disclosed technologies provide a carrier frequency selecting method and apparatus. The method comprises: determining, by UE, whether information of a service carrier frequency sent by a base station is received, wherein the service carrier frequency is the carrier frequency to carry traffic selected by the base station when a target cell carrying the UE is a multi-carrier cell; residing, by the UE, at a carrier frequency corresponding to the information for a service carrier frequency, if so; and, otherwise, residing, by the UE, at an original camped carrier frequency. With the embodiments of the disclosed technologies, the problem that a service carrier frequency selecting strategy in related techniques is to perform selection passively and lacks initiative is solved, and a technical basis for balancing loads on carrier frequencies carrying traffic is provided and further system efficiency is enhanced for an NB-IoT system, which is mainly to transmit small data.

Abstract: A method, user equipment, network device, and software product enable allocation of a number of resource blocks over a downlink to the user equipment. The resource blocks are grouped into a number of groups of the blocks, the number of groups being no greater than a maximum number. The resource blocks are arranged in an adjacent manner within each of the groups. The resource blocks are allocated by operating on the groups, and the allocation is signalled using a group allocation indication.
