Abstract: Embodiments of the present invention provide a control channel position determining method, a device, and a processor-readable storage medium. A terminal device determines an available unlicensed band set and a control channel resource group, and determines at least one first unlicensed band to which at least one of control channel resource groups belongs, based on bitmap information or offset information. The at least one first unlicensed band belongs to the available unlicensed band set. Compared with that a control channel resource group is semi-statically configured to belong to a first unlicensed band, according to the embodiments of the present invention, no matter how an available unlicensed band included in an available unlicensed band set changes, a first unlicensed band to which at least one control channel resource group belongs can always be determined, thereby ensuring normal communication.

Abstract: This application relates to a scheduling method, an apparatus, and a system. A first communications apparatus sends first signaling on a first resource, where the first signaling is used to indicate N communications apparatuses. The first communications apparatus sends second signaling on a second resource, where the second signaling is used to schedule the N communications apparatuses to send or receive first data, and the first resource has an association relationship with the second resource. In addition, the first resource has the association relationship with the second resource. In this case, a receive end of the first signaling and the second signaling may determine the second resource after determining the first resource, so that the second signaling is only detected on the second resource, and blind detection does not need to be performed on too many resources.

Abstract: A target detection method includes a radar apparatus that performs at least one interference sensing on a plurality of first time domain resources and determines a second time-frequency resource used for target detection in a first time-frequency resource based on a result of the at least one interference sensing. The first time domain resources are a subset of time domain resources corresponding to a time-frequency resource of a first detection apparatus, and the first time-frequency resource is the time-frequency resource of the first detection apparatus.

Abstract: A radar signal sending method and a device provides for the sending of the radar signal to cooperative radars. A first time domain range in L time domain ranges is determined. A first radar signal is sent in the first time domain range. Any one of the L time domain ranges partially overlaps at least one of the other (L−1) time domain ranges, and an absolute value of a difference between time domain start locations of any two of the L time domain ranges is greater than or equal to a first threshold and less than or equal to a second threshold.

Abstract: A method for detecting a target object implemented by a detection apparatus, where the detection apparatus transmits a radio signal on a frequency band on which mutual interference can be avoided to avoid or reduce interference caused by a transmit signal or a related signal of any detection apparatus when another detection apparatus determines a target. The detection apparatus divides a frequency band or a frequency domain raster based on a determined threshold to allow partial overlapping between frequency bands or rasters.

Abstract: The present disclosure provides an information processing method and apparatus. A terminal device encodes uplink control information (UCI) to obtain coded bits of the UCI, and encodes data to obtain coded bits of the data. The terminal device multiplexes the coded bits of the UCI and the coded bits of the data to obtain a multiplexed bit sequence. The terminal device then transmits the multiplexed bit sequence to a network device via a physical uplink shared channel (PUSCH). A length of a transmission time interval of the UCI is less than or equal to 0.5 millisecond. In this way, data transmission latency can be reduced.

Abstract: Various embodiments provide a communication method. The method includes: determining, by a terminal device, first uplink control information and second uplink control information. In those embodiments, a length of a time domain resource corresponding to the first uplink control information is less than a length of a time domain resource corresponding to the second uplink control information. The first uplink control information or the second uplink control information comprises at least one of hybrid automatic repeat request information, channel state information, and scheduling request information. When the time domain resource corresponding to the first uplink control information overlaps with the time domain resource corresponding to the second uplink control information, the terminal device is configured to transmit third uplink control information on the overlapping time domain resource.
