Abstract: The present disclosure provides a method and a device in a User Equipment (UE) and a base station for wireless communications. A UE receives first information, the first information being used for indicating M DCI blind decoding(s); monitors a first-type radio signal respectively on each of S sub-band(s) in a first time-domain resource; and performs at most M1 DCI blind decoding(s) of the M DCI blind decoding(s) on the S sub-band(s) in the first time-domain resource. Herein, the first-type radio signal detected on the S sub-band(s) is used for determining the M1 DCI blind decoding(s) out of the M DCI blind decoding(s). The above method allows the base station to make dynamic adjustments to the UE's blind decoding on PDCCH resources according to LBT results, ensuring that sufficient PDCCH resources are available and not too many PDSCH resources are preempted, and that excessive blind decodings can be avoided.

Abstract: The discloses a method and device in a user equipment and a base station for wireless communication. The user equipment receives a first signaling, wherein the first signaling is used to determine a first time-frequency resource group, and the first time-frequency resource group is reserved for a first bit block; receives a second signaling, wherein the second signaling is used to determine a second time-frequency resource group, and the second time-frequency resource group is reserved for a second bit block; and transmits the first bit block and the second bit block in the second time-frequency resource group, or transmits only the second bit block. Time domain resource(s) occupied by the first time-frequency resource group and the second time-frequency resource group are non-orthogonal; a timing relationship between the first signaling and the second signaling is used to determine whether the first bit block is transmitted in the second time-frequency resource group.

Abstract: The present disclosure provides a method and a device in a UE and a base station for wireless communication. The UE receives a first signaling in a first resource element set and a first radio signal. The first resource element set determines a first information set out of M information sets; any information set of the M information sets comprises a positive integer number of information element(s) comprising a first type index and a second type index set comprising at least one second type index; the first signaling comprises scheduling information of the first radio signal, the first signaling comprises a first field indicating a first information element out of the first information set; a measurement on a reference signal identified by a second type index comprised in the first information element for reception of the first radio signal. The above method helps reduce overhead for scheduling signaling.

Abstract: The present disclosure discloses a method and a device in a User Equipment (UE) and a base station used for wireless communication. The UE receives a first signaling, the first signaling being used for indicating a first time-frequency resource group, the first time-frequency resource group being reserved for a first bit block; and receives a second signaling, the second signaling being used for indicating a second time-frequency resource group, the second time-frequency resource group being reserved for a second bit block. Whether the first time-frequency resource group and the second time-frequency resource group belong to a same resource subset of G resource subsets is used for determining whether the first bit block and the second bit block are respectively transmitted in the first time-frequency resource group and the second time-frequency resource group or are both transmitted in a third time-frequency resource group.

Abstract: The present disclosure provides a method and a device in a first node and a base station for wireless communication. A first node transmits K1 first-type reference signal(s), and operates a first radio signal and a second radio signal; the K1 first-type reference signal(s) is(are) transmitted by K1 first-type antenna port set(s) respectively, a target antenna port set is a first-type antenna port set in the K1 first-type antenna port set(s); a first antenna port set and a second antenna port set are respectively used for transmitting the first radio signal and the second radio signal. The disclosure makes it practical for the first node to simultaneously operate radio signals transmitted from different transmitters in beamforming scenarios by connecting a first antenna port set and a second antenna port set with a target antenna port set, thereby improving the reception and transmission efficiency and the entire performance of the system.

Abstract: Embodiments determine the species of trees present in an aerial image. Tree crowns are detected in a received image, and represented as histograms of their color, texture and entropy features. Similar trees are clustered together. Using classification techniques, each cluster is assigned the closest species. The species information for each tree may be used in a rendering of the tree in geographical information systems.
