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.

Dependent claims

A method performed by a wireless communication device, comprising:

receiving a System Information Block (SIB) message from a wireless communication node;
and
determining a transmission mode and a transmission configuration for a NarrowBand Physical Downlink Control Channel (NB-PDCCH), a NarrowBand Downlink Shared Channel (NB-PDSCH), or a NarrowBand Uplink Shared Channel (NB-PUSCH) based on the SIB message independently of timing of transmissions on the NB-PDCCH, NB-PDSCH or NB-PUSCH,
wherein the transmission mode is one of the following:
continuous and non-continuous transmission,
wherein the transmission configuration comprises a plurality of predetermined periods and a plurality of predetermined gap durations, wherein each of the plurality of predetermined periods comprises a first number of subframes, wherein:
the first number of subframes in each of the plurality of predetermined periods is less than or equal to a threshold value;
and
a second maximum number of repetitions of NB-PDCCH, NB-PDSCH or NB-PUSCH subframes is greater than the threshold value, and
wherein when the transmission mode is non-continuous, each of the plurality of predetermined gap durations divides a single continuous transmission on the NB-PDCCH, NB-PDSCH or NB-PUSCH into two parts.
