Abstract: A disclosure of the present specification provides a method for performing measurement on a physical sidelink discovery channel (PSDCH) including a discovery signal from an adjacent terminal. The method may comprise the steps of: when, among PSDCHs repeatedly transmitted from an adjacent terminal in n subframes, a PSDCH in a kth subframe is successfully decoded and thereby the cyclic redundancy check (CRC) thereof succeeds, regarding the CRC of PSDCHs in the subsequent n−k subframes as successful without decoding the same; and performing measurements in the kth subframe and the subsequent n−k subframes for which the CRC is regarded as successful.

Abstract: Coordination and synchronization is performed between two or more wireless network managers (e.g., access points (APs)). A first wireless network manager supports first communications with first other wireless communication devices, and a second wireless network manager supports second communications with those first and/or second other wirelessly case devices. The first and second wireless network managers also support communications with one another to coordinate the first and second communications supported with the first and/or second other wireless communication devices. Examples of coordination include selection of which other wireless communication devices are serviced or in communication with which of the first and second wireless network managers, selection of operational parameters (e.g., modulation coding set (MCS), beamforming, frequency band assignment, channel assignment, scheduling information, transmit power, etc.) for the first and second wireless communication devices, synchronization to a common clock (e.g., using timing synchronization function (TSF)).

Abstract: A radio node (52) in a wireless communication system (10) employs multiple different candidate formats (22) that define different possible positions of decoding checks (24) within a transport block of a specific size. The radio node (52) determines, from these different candidate formats (22), a format that defines a position of decoding checks (24) within a transport block (16) to be encoded or decoded. The radio node (52) then encodes or decodes at least a portion of the transport block (16) based on the determined format.

Abstract: Wireless devices and methods presented in the disclosure provide for block acknowledgements for multi-band transmissions. The block acknowledgements can be coupled (aggregated) for two or more flows across multiple bands by using an acknowledge aggregation methodology. The method creates a single multi-band common acknowledgment that can be sent over one band to acknowledge transmissions over two or more bands.

Abstract: Disclosed is a method and apparatus for transmitting information in a communication system. The present invention relates to a millimeter wave beamforming-based 5G or pre-5G wireless communication system for supporting a higher data rate beyond a 4G network or LTE system. A method according to the present invention comprises the steps of: determining the number of blocks and a window size for configuring a transmission period for sliding window superposition coding (SWSC); transmitting control information including the determined number of blocks and window size to a plurality of terminals participating in the SWSC; transmitting, in a first block within the transmission period, a signal in which a first message and a second message are superposition-coded by first and second codes; and when a message notifying that the first message is not successfully decoded is received, transmitting, in a second block, a signal in which the second message and the first message are superposition-coded by the first and second codes.
