Abstract: According to a first aspect, there is provided a method for controlling uplink access transmissions in a radio communication system, wherein a user equipment determines a delay time for transmitting a signal on an uplink access channel, wherein the delay time is randomly determined based upon a probability distribution that increases in density with increasing delay. According to a second aspect, there is provided a method for controlling uplink access transmissions in a radio communication system, wherein from a base station of the radio communication system, time variable information is signalled in downlink to user equipments located in an area covered by the base station, wherein the information is used to determine delay times for transmitting signals on an uplink access channel and wherein the information varies based upon a probability distribution which increases in density with increasing time.

Abstract: A method in a wireless communication device and an apparatus, such as a wireless communication device, for reporting a channel quality indication to non-serving cells. The device can operate on a shared channel on a serving cell. The device can send a channel quality indicator message on a medium access control layer to multiple candidate cells in an active set of cells. The device can then switch from the serving cell to a new serving cell from the multiple candidate cells based on information in the channel quality indicator message.

Abstract: A mobile wireless communication terminal, for example, 3G UMTS user equipment (UE), and methods including receiving (310) a notification of a change in a cell serving the mobile wireless communication terminal, and transmitting (320) scheduling information to a new serving cell in response to receiving the notification of the serving cell change. In the 3G UMTS applications, the notification is an enhanced dedicated channel (E-DCH) allocation, and the scheduling information includes buffer and transmitting power headroom information is transmitted in an enhanced medium access control (MAC-e) protocol data unit (PDU).
