摘要： The invention relates to methods for adjusting the transmit power utilized by a mobile terminal for uplink transmissions, and to methods for adjusting the transmit power used by a mobile terminal for one or more RACH procedures. The invention is also providing apparatus and system for performing these methods, and computer readable media the instructions of which cause the apparatus and system to perform the methods described herein. In order to allow for adjusting the transmit power of uplink transmissions on uplink component carriers, the invention suggests introducing a power scaling for uplink PRACH transmissions performing RACH procedures on an uplink component carrier. The power scaling is proposed on the basis of a prioritization among multiple uplink transmissions or on the basis of the uplink component carriers on which RACH procedures are performed.

摘要： Methods and devices are provided for implementing two types of sub-channel arrangements. A first type of sub-channel arrangement involves defining a first traffic portion and a second traffic portion of a transmission resource, transmitting broadcast traffic on at least one first antenna of a plurality of antennas in the first traffic portion using a first sub-channelization, transmitting multicast traffic on at least one second antenna of the plurality of antennas, the at least one second antenna being distinct from the at least one first antenna, in the first traffic portion using a second sub-channelization, and transmitting unicast traffic on at least one antenna of the plurality of antennas in the second traffic portion using a third sub-channelization. A second type of sub-channel arrangement involves defining a first traffic portion and a second traffic portion, wherein for a portion of the transmission resource, a portion of the first traffic portion overlaps with a portion of the second traffic portion. In the portion of the transmission resource in which a portion of the first traffic portion overlaps with a portion of the second traffic portion, the channel arrangement involves transmitting broadcast/multicast traffic on at least one first antenna of a plurality of antennas using a first sub-channelization and b) transmitting unicast traffic on at least one second antenna of the plurality of antennas, the at least one second antenna being distinct from the at least one first antenna, using a second sub-channelization. The first, second and third sub-channelizations may be based on either one of or a combination of FDM sub-channelization and TDM sub-channelization.

摘要： Power control in a communication system (100) employing a Downlink Shared Control Channel (DSCH) and a Forward Access Control Channel (FACH) is described. The method includes, applying power control on the Downlink Shared Control Channel; deriving power control information from the power control on the Downlink Shared Control Channel; and applying to the Forward Access Control Channel the derived power control information from the power control on the Downlink Shared Control Channel in order to produce power control on the Forward Access Control Channel. The power control of the Forward Access Control Channel may be implemented by scheduling data in response to the derived power control information.
