A radio communication apparatus includes: a first radio device; a second radio device; and an operation unit, in which: in the first radio device, at least one of a plurality of channels usable by the first radio device is defined as a first priority channel, the first priority channel being a channel on which a radio wave is preferentially detected; and when a signal is transmitted on a channel other than the first priority channel in response to an operation performed on the first radio device based on an input from the user received through the operation unit, channel information indicating the first priority channel is transmitted to the second radio device, and the second radio device starts detecting a radio wave on the channel indicated by the channel information.

A terminal according to an aspect of the present disclosure includes a receiving section that receives downlink control information including information related to a resource for which an UL transmission is canceled, and a control section that performs control to first apply one of first UL transmission control and second UL transmission control and then apply the other when a plurality of UL transmissions that overlap in a time domain are scheduled or configured and at least one of the plurality of UL transmissions uses the resource for which the UL transmission is canceled, the first UL transmission control being based on a priority of each UL transmission, the second UL transmission control being based on information related to the resource for which the UL transmission is canceled.

Embodiments of the present application relate to a method and an apparatus for or small data transmission of a user equipment (UE) in an RRC_IDLE state or an RRC_INACTIVE state. According to an embodiment of the present application, a method can include: a method may include maintaining a priority variable for each logical channel of at least one logical channel; determining a value of the priority variable for each logical channel after performing a first logical channel prioritization (LCP) procedure; receiving a message indicating a MAC reset; and after receiving the message, in a second LCP procedure subsequent to the first LCP procedure, using the value as an initial value of the priority variable for each logical channel of the at least one logical channel. Embodiments of the present application can satisfy the QoS requirement and fairness for the traffics transmitted in the logical channels in NR systems.

Provided are methods and apparatuses for transmitting and receiving control signaling and for determining information. The method include determining second information according to first information, where the second information includes at least one of the following: the number N of bits used in first control signaling to notify a first transmission parameter, a correspondence mapping table between an index value referenced by the first transmission parameter in the first control signaling and the value of the first transmission parameter, the type of the first transmission parameter notified by a predetermined indication field in the first control signaling, or position information of the bits used in the first control signaling to notify the first transmission parameter; and where the first information includes a relationship between a transmission time interval between the first control signaling and a first signal and a predetermined threshold K, where N and K are non-negative integers; and transmitting the first control signaling.

An apparatus configured to operate in a wireless communication network by generating and transmitting a first wireless signal using a resource element allocated to the apparatus is configured to receive a second wireless signal and to determine that the second wireless signal is to be forwarded within the wireless communication network. The apparatus is configured to transmit a third wireless signal based on the second wireless signal instead of the first wireless signal using the allocated resource element of the wireless communication network.

Embodiments of a User Equipment (UE) to support dual-connectivity with a Master Evolved Node-B (MeNB) and a Secondary eNB (SeNB) are disclosed herein. The UE may receive downlink traffic packets from the MeNB and from the SeNB as part of a split data radio bearer (DRB). At least a portion of control functionality for the split DRB may be performed at each of the MeNB and the SeNB. The UE may receive an uplink eNB indicator for an uplink eNB to which the UE is to transmit uplink traffic packets as part of the split DRB. Based at least partly on the uplink eNB indicator, the UE may transmit uplink traffic packets to the uplink eNB as part of the split DRB. The uplink eNB may be selected from a group that includes the MeNB and the SeNB.
