Abstract: The present disclosure relates to a method for paging coverage extension UEs in a cell controlled by a radio base station. At least one CE-specific paging possibility is defined for paging CE-UEs. The CE-UEs in the cell regularly monitor the at least one CE-specific paging possibility. When the radio base station determines to page all the user equipments in the cell, it pages the CE user equipments in the cell at the CE-specific paging possibility, using a coverage extension technique. The disclosure also relates to a method for paging a CE-UE, which performs radio measurements by a CE-capable user equipment to determine whether coverage extension is necessary. The radio base station is informed about whether the CE-capable user equipment needs coverage extension and then pages the CE-UEs applying or not applying a CE technique depending on whether coverage extension is necessary.

Abstract: A controller, which is a communication device, includes: a transfer unit including a function of transferring data received from a first terminal to another communication device via wireless communication; and a determination unit configured to determine whether first information is included in the data received by the transfer unit, the first information indicating that the data is to be multicast. The transfer unit is further configured to multicast the data to a second terminal when the determination unit determines that the first information is included in the data, the second terminal and the first terminal being different terminals.

Abstract: When a plurality of the subcarrier spacing values are applied, a reference signal is generated by using a sequence having a sequence length corresponding to a first ratio of a first subcarrier spacing set for transmission data to the maximum settable subcarrier spacing. The sequence of the reference signal is mapped to a frequency resource at mapping intervals in accordance with a second ratio which is the reciprocal of the first ratio, and the transmission data and the reference signal are transmitted.

Abstract: The present disclosure relates to enabling and disabling of codewords in multi-subframe grants. In particular, dynamic and subframe based enabling/disabling of codewords is enabled even if other control parameters including the resource allocation is performed for multiple subframes. For instance, signal from a scheduling entity to a scheduled entity comprises control information including the resource grant common for multiple subframes and a plurality of codewords for each subframe, and a codeword indication indicating enabling or disabling of one or more codewords for each of the multiple subframes. For each subframe it is determined whether a codeword from the plurality of codewords in said subframes is enabled or disabled according to the codeword indication and/or which codeword is enabled or disabled. The indication of enabling and disabling may alternatively be done by using modulation and coding scheme indicator values which are not associated with a particular modulation and coding scheme.

Abstract: An encoder includes memory and circuitry configured to determine a merge mode to be applied to a current block, wherein the merge mode includes a sub-block merge mode and a first merge mode. In the merge mode, inter-prediction parameters are inferred from a neighboring block neighboring the current block. In the sub-block merge mode, the current block includes a plurality of sub-blocks, and inter-prediction parameters are provided for each of the plurality of sub-blocks. When the merge mode is determined to be the first merge mode, the circuitry generates a prediction image for the current block by performing a bi-directional optical flow prediction process, wherein the bi-directional optical flow prediction process uses a spatial gradient for the current block. When the merge mode is determined to be the sub-block merge mode, the circuitry generates a prediction image for the current block by not performing the bi-directional optical flow prediction process.
