摘要： To improve throughput of the whole system while reducing power consumption. In a mobile communication system comprising a mobile station apparatus and a base station apparatus, the base station apparatus creates an interference information table based on channel quality of an uplink channel, and at the same time, transmitting the interference information indicator table to the mobile station apparatus, and the mobile station apparatus determines a state of interference in an uplink frequency band based on the interference information indicator table, determines a frequency band of a measurement pilot channel, which is a pilot channel used to determine received quality, and make a request to the base station apparatus for a transmission resource. For example, the mobile station apparatus determines a frequency band with lowest interference among the uplink frequency bands as a frequency band of the measurement pilot channel.

摘要： In a mobile station, correction information is obtained from a base station for correcting a transmission timing shift in an uplink line of the mobile station, and the transmission timing shift is corrected in accordance with the correction information. Within a period in which the correction information is valid, the mobile station requests communication resource allocation information from the base station, using a random access channel having guard time. In an alternate embodiment, if a communication resource for transmitting a control channel in the uplink line is assigned to the mobile station within a period during which the correction information is valid, the mobile station instead requests the communication resource allocation information from the base station using the control channel in an uplink line from the mobile station to the base station.

摘要： A User Equipment (UE) for selecting a Channel State Information (CSI) report is described. The UE includes a processor and memory in electronic communication with the processor. Executable instructions are stored in the memory. The UE generates multiple CSI reports corresponding to at least one serving cell. A group of one or more CSI reports with a same association forms a CSI report set. The UE applies a first prioritization rule to select a single CSI report for each CSI report set and drops at least one first prioritization unselected CSI report if there is an intra-set transmission scheduling collision. The UE also applies a second prioritization rule to select at least one CSI report if there is an inter-set transmission scheduling collision.
