摘要： The present disclosure discloses a method and device for multi-antenna transmission in UE and base station. The user equipment receives a first radio signal at first, then receives a first signaling. The first radio signal is transmitted by K antenna port groups, and the first signaling is used to determine a first time resource pool; a second antenna virtualization vector is associated with the first antenna port group; the second antenna virtualization vector is an antenna virtualization vector available to the user equipment in the first time resource pool.

摘要： The present disclosure provides a method and device in User Equipment (UE) and a base station for dynamic scheduling. The UE first receives first information; and then receives second information; and operates a first radio signal. Wherein the first information comprises Q field(s), a first field is used to determine a first antenna port set, the first field is one field of the Q field(s). The first antenna port set comprises a positive integer of antenna port(s), the second information is transmitted by an antenna port within the first antenna port set. The first information and the second information are both dynamically configured. The operating refers to receiving, or the operating refers to transmitting. The second information is used to determine scheduling information of the first radio signal. The present disclosure ensures the robustness of scheduling signaling reception in multi-antenna scenarios, and also avoids excessive overhead, hence improving transmission efficiency.

摘要： A method and a device for multi-antenna transmission in a user equipment and a base station are disclosed in the present disclosure. The user equipment first receives a first signaling, receives a first wireless signal, and transmits first information. K antenna port groups are used to transmit the first wireless signal. The first signaling is used to determine the K antenna port groups. The K antenna port groups respectively correspond to K channel quality values. K1 antenna port groups of the K antenna port groups correspond to K1 channel quality values of the K channel quality values. The K1 is a positive integer less than or equal to the K. A first proportional sequence corresponds to a ratio(ratios) among the K1 channel quality values. The first information is used to determine the K1 antenna port groups and the first proportional sequence.

摘要： A wireless device may receive configuration parameters of a plurality of cells and a SR configuration. The SR configuration may be associated with recovery from consistent LBT failure. The SR configuration may be for requesting resources on one or more first cells of the plurality of cells and excluding resources on other cells of the plurality of cells. No resources on one or more cells for which the consistent LBT failure is not triggered may be available for transmission of an LBT failure control element. The wireless device may transmit a SR based on the SR configuration. The wireless device may receive an uplink grant for a first cell of the one or more first cells. The wireless device may transmit the LBT failure control element based on the uplink grant.
