摘要： The present invention relates to a transmitting device. The transmitting device (100) comprises a processor (102), and a transmitter (104); wherein the processor (102) is configured to generate a fractional Orthogonal Frequency Division Multiplexing, OFDM, symbol based on an adjacent OFDM symbol, wherein the fractional OFDM symbol is a cyclic extension of the adjacent OFDM symbol; wherein the transmitter (104) is configured to transmit a multicarrier signal comprising the fractional OFDM symbol and the adjacent OFDM symbol. Furthermore, the present invention also relates to a corresponding method, a multicarrier wireless communication system comprising such a transmitting device, a computer program, and a computer program product.

摘要： An optical transmitting apparatus and an electronic device are provided, and relate to the field of optical and electronic device technologies. The optical transmitting apparatus includes: an array light source (401), a collimating lens (402), a rotatable scanning mirror (403), and an optical beam splitter (404). The array light source (401) may include M rows and N columns of light sources, both M and N are positive integers, and an included angle between any column of light sources in the N columns of light sources and any row of light sources in the M rows of light sources is a preset angle. The array light source (401) is located on a first side of the collimating lens (402), a plane on which the array light source (401) is located is perpendicular to an optical axis of the collimating lens (402), and a distance between the plane on which the array light source (401) is located and a center point of the collimating lens (402) is a focal length of the collimating lens (402). The rotatable scanning mirror (403) is located on a second side of the collimating lens (402), and a center point of a reflective surface of the rotatable scanning mirror (403) is on the optical axis of the collimating lens (402). Requirements on a rotation angle of the rotatable scanning mirror (403) in the optical transmitting apparatus are reduced, and utilization of a light beam emitted by the optical transmitting apparatus is improved.

摘要： This application relates to the field of communications technologies, and discloses a channel quality information determining method, an apparatus, and a system. The method includes: A terminal device obtains a configured TBS, and determines channel quality information of each of K segments of frequency domain resources based on the TBS and a time domain resource range. A frequency domain resource of the terminal device is divided into N segments, where both N and K are integers greater than or equal to 1, and K is less than or equal to N. In embodiments of this application, the TBS is fully considered when the channel quality information is determined, so that a network device properly determines, based on the channel quality information, a frequency domain resource used to transmit a data packet.

摘要： An uplink resource grant method includes: receiving, by a terminal, configuration information from a network device, where the configuration information includes information about a first uplink resource and information about a second uplink resource; and searching, by the terminal, a search space for a downlink control channel to obtain grant information. The search space includes a first control channel candidate set when the downlink control channel carries grant information of the first (or the second) uplink resource, and the search space includes a second control channel candidate set when the downlink control channel carries grant information of the second (or the first) uplink resource and/or grant information of a downlink resource. The first control channel candidate set is the same as the second control channel candidate set; or the first control channel candidate set has an offset with respect to the second control channel candidate set, and a quantity of control channel candidates in the first control channel candidate set is less than a quantity of control channel candidates in the second control channel candidate set. In this method, blind detections of the terminal are reduced by sharing search space or by reducing a quantity of control channel candidates used when grant information of an uplink resource is carried.

摘要： This application provides a resource allocation method, user equipment, and a network device. The method includes: determining a first location of a first frequency domain resource; determining a second location of at least one bandwidth part based on the first location and an offset between the first location and the second location; determining the at least one bandwidth part based on the second location of the at least one bandwidth part and a bandwidth size of the at least one bandwidth part; and transmitting at least one of physical signal information and physical channel information in a first bandwidth part, where the first bandwidth part includes one or more bandwidth parts in the at least one bandwidth part. In embodiments of this application, the user equipment can determine a location of a frequency domain resource without depending on a system bandwidth size, that is, UE can allocate resources even if the UE does not know a system bandwidth.

摘要： This application provides an information monitoring method, a terminal, and a network device. The method includes: allocating, by a network device, a first frequency domain resource to a terminal, where the first frequency domain resource is used as a bandwidth part of the terminal; obtaining, by the network device, a bandwidth capability of the terminal, and determining, based on the bandwidth capability and the first frequency domain resource, a second frequency domain resource allocated to the terminal, where the second frequency domain resource is used by the terminal to monitor common information; and sending, by the network device, indication information, where the indication information is used to indicate the second frequency domain resource. According to embodiments of this application, common information and information about a terminal can be simultaneously monitored, thereby improving information monitoring efficiency.
