Abstract: Various communication systems may benefit from appropriate configuration of available bandwidth. These and other communication systems, such as wireless communication systems, may benefit from resource indication for a larger channel bandwidth. One example is further enhanced machine type communication. A method can include determining, by a radio network node, a bandwidth for allocation to a user equipment. The allocated bandwidth can include resources in a single narrowband or a plurality of narrowbands. The method can also include indicating to the user equipment the single narrowband or the plurality of narrowbands and allocated resources in the single narrowband or the plurality of narrowbands.

Abstract: Example embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of extended bandwidth allocation. In example embodiments, a first device receives, from a second device, an indication of a reference bandwidth. The first device receives, from the second device, an indication of a bandwidth extended from the reference bandwidth and receives, from the second device, an indication of at least one frequency offset of a first set of narrowbands with respect to a second set of narrowbands associated with the reference bandwidth. Then, the first device determines, based on the reference bandwidth, the extended bandwidth and the at least one frequency offset, the first set of narrowbands for communication with the second device.

Abstract: Method, apparatus and computer program product where a base station broadcasts a signal indicating that at least one time-frequency region, which is unused by a data transmission in a first radio access technology, is available for a transmission, allowing the base station to maintain support for and/or extending coverage of certain legacy user equipment. Such a transmission includes system information for a second radio access technology, wake-up signal, synchronization signal, and/or extension of the data transmission. Thereafter, the base station transmits such a transmission in the at least one time-frequency region that was indicated.

Abstract: Embodiments of the present invention generally relate to enhanced physical downlink control channel (EPDCCH) search space determination. In one embodiment, a base station may identify an index of the current EPDCCH occasion period, each EPDCCH occasion period including a number of subframes, and the subframes being divided to a number of search units. A distribution of EPDCCH candidates corresponding to at least one EPDCCH aggregation level in the EPDCCH occasion period may be determined based on the index of the EPDCCH occasion period and the number of search units in the EPDCCH occasion period. The base station may then select, from the distribution of the EPDCCH candidates, an EPDCCH candidate for transmitting downlink control information (DCI) to a UE.

Abstract: A method and apparatus may include receiving an uplink grant in a specific subframe of a frame and/or a physical hybrid-ARQ indicator channel transmission, for a physical-uplink-shared-channel transmission or retransmission on a special subframe. The method may also include determining that the uplink grant validates transmitting a physical-uplink-shared-channel transmission on the special subframe, or that the physical hybrid-ARQ indicator channel transmission validates transmitting a physical-uplink-shared-channel retransmission on the special subframe. The method may also include determining transmission parameters for transmitting the physical-uplink-shared-channel transmission or retransmission. The method may also include transmitting the physical-uplink-shared-channel transmission or retransmission on the special subframe.

Abstract: Various communication systems may benefit from time discontinuous transmission. For example, narrow band Internet of things (NB-IoT) may benefit from having transmissions with sufficient time diversity to avoid unnecessary repetition. A method can include configuring a control channel and data channel partitioning pattern within a configured time period. The method can additionally include communicating with at least one user equipment based on the control channel and data channel partitioning pattern.
