Two-state automatic gain control for communications and radar

Various communication systems may benefit from appropriate configuration of reception states. For example, certain wireless communication systems, such as new radio, may benefit from control monitoring upon receipt of a discontinuous reception trigger. A method can including receiving, by a user equipment, configuration of a search space set of a downlink control resource set with a first monitoring periodicity. The method can also include receiving a trigger or the user equipment becoming active after a period without physical downlink control channel (PDCCH) monitoring. The method can further include, after the receiving of the trigger or the becoming active, modifying a monitoring periodicity of the search space set to a second monitoring periodicity.

Control monitoring upon receipt of discontinuous reception trigger

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.

Apparatuses and methods for managing blind searches

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.

Flexible indication of transmission timing

A method and apparatus for implicitly determining a PUCCH resource. The invention allows for flexible selection of a PUCCH resource in the PUCCH resource subset for configurations of PDCCH resources without collisions through the use of indices for control channel element subsets.

Selection of physical uplink control channel resources

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.

Managing control channel blind searches between search spaces in new radio

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.

A vehicle messaging transmission method, a vehicle messaging transmitter, a vehicle messaging reception method, a vehicle messaging receiver, an infrastructure node method, and infrastructure node and computer program products are disclosed. The vehicle messaging transmission method, comprises: detecting a vehicle event; and transmitting both a vehicle-to-vehicle message over a vehicle-to-vehicle radio link, the vehicle-to-vehicle message identifying the vehicle event and a vehicle-to-infrastructure message over a vehicle-to-infrastructure radio link, the vehicle-to-infrastructure message identifying the vehicle event. In this way, rather than periodically transmitting location messages, instead messages are only transmitted when a particular event occurs. This helps to reduce the volume of messages since the messages are only transmitted when an event occurs. Also transmitting a vehicle-to-vehicle message enables messages to be transmitted quickly, with reduced latency. Furthermore, because the messages are only sent when an event occurs, privacy and security concerns are reduced. As will be explained in more detail below, transmitting a vehicle-to-vehicle message enables other vehicles which receive the message to receive that message quickly and to respond rapidly to the event, while the vehicle-to-infrastructure message can be used to authenticate the validity of the vehicle-to-vehicle message and provide additional assurance to the receiving vehicle that the message is genuine.
