Abstract: One radar excitation signal has a first burst duration and a first sampling period. Another radar excitation signal has a second burst duration and a second sampling period. The first sampling period of the first signal is configured for scanning a velocity range and the second sampling period of the second signal is configured for scanning a portion of the velocity range, and the first burst duration is smaller than the second burst duration. The at least two radar excitation signals are embedded into a frame structure for a wireless communications system. At least one radar operation comprising at least one transmission based on the frame structure is performed. In this way the overhead of the radar excitation signals on the air interface of the wireless communications system may be controlled, while supporting a fine velocity resolution and a sufficiently large maximum velocity for a monitored target.

Abstract: Systems, methods, apparatuses, and computer program products for managing or monitoring of the control channel in new radio (NR) through blind searches are provided. One method may include determining whether a channel estimation limit has been reached for a user equipment. When it is determined that the channel estimation limit has been reached, the method may include selecting blind decoding candidate(s) to be dropped from different control resource set(s) or search space set(s), and removing the selected blind decoding candidate(s) from a set of monitored candidates.

Abstract: Disclosed are example embodiments of method and apparatus supporting narrowband system information modification indications based on synchronization raster positions. A terminal device may comprise at least one processor and at least one memory including computer program code. The at least one memory and the computer program code may be configured to, with the at least one processor, cause the terminal device to determine a first frequency position of a synchronization signal, and apply a first scheme to decode at least a part of system information received from a network, responsive to the determined first frequency position of the synchronization signal. The first frequency position is different from a second frequency position, and the first scheme is different from a second scheme which is applicable for decoding the part of the system information when the synchronization signal is at the second frequency position.

Abstract: Systems, methods, apparatuses, and computer program products for managing or monitoring of the control channel in new radio (NR) through blind searches are provided. One method may include configuring, by a network node, multiple search spaces, sets of search spaces, and/or control resource sets, to a user equipment, that results in monitoring occasions where more blind decodings are required than allowed by capability of the user equipment. The method may further include identifying the monitoring occasions for which an allowed number of blind decodings is exceeded, determining a reduced set of blind decodings and/or candidates determined by predefined search space priorities or rules, and transmitting physical downlink control channel(s) to the user equipment given the reduced set.

Abstract: A spreading sequence is determined (S301) based on a candidate of a control channel of a control resource set, the candidate comprising a sequence of control information. The sequence of control information and the determined spreading sequence are multiplied (S303), thereby obtaining a spread series of control information.

Abstract: Various communication systems may benefit from allocation of candidates for a channel. For example, some new radio communication systems may benefit from hashing for allocation of control channel candidates. A method can include applying a hashing function for associating a plurality of decoding candidates of a search space set with subsets of control channel elements of a control resource set, and using the decoding candidate for scheduling of a user equipment in a control channel, wherein the hashing function is non-uniform in a pseudo-random manner and with one candidate per subband. The method can also include scheduling the user equipment based on the applied hashing function.

Abstract: Various communication systems may benefit from improved signaling. For example, anew radio communication system may benefit from a flexible indication of transmission timing. A method may include determining, at the user equipment, transmission timing based on a first parameter and a second parameter. The first parameter may indicate an offset as a number of slots. The second parameter may indicate an offset as a number of symbols within one of the slots. The method may also include using the transmission timing to at least one of send an uplink transmission or receive a downlink transmission.
