摘要:
Methods and apparatus for distributing available transmit power in a user equipment (UE) to avoid violation of UE power limitations on a Physical Uplink Control Channel (PUCCH) and a Physical Uplink Shared Channel (PUSCH) are described. Available power for transmission on at least the PUCCH is determined and at least one power headroom report indicating available power for transmission on at least the PUCCH is transmitted to a base station.

The invention is a method and apparatus for signaling uplink control information in a mobile communication network using carrier aggregation. The signaling mechanism allows the transmission, on a single uplink component carrier, of control information associated with a downlink transmission on multiple aggregated downlink component carriers. Semi-statically reserved resources for the transmission of control information on the uplink component carrier may be dynamically shared by user terminals that are assigned multiple downlink component carriers for downlink transmissions. Implicit or explicit resource indication can be used in combination with dynamic resource indication.

The present invention relates to methods and arrangements for assisting a User Equipment (UE) to determine transmit power to be used on a first uplink component carrier y, wherein the base station is configured to communicate with the UE over a plurality of uplink and downlink component carriers x,y. The UE is aware of path loss parameters associated with a second downlink component carrier x. The method in a base station comprises determining cell specific path loss parameters associated with the component carriers of the base station. The cell specific path loss parameters at least comprises path loss parameters associated with the first uplink component carrier y and a second uplink component carrier x which is paired to the second downlink component carrier x, wherein the second uplink component carrier and second downlink component carrier are within one frequency band. The method comprises the further steps of calculating a pathloss offset, deltaPL(y,x), for the first uplink component carrier y, wherein the pathloss offset deltaPL(y,x) is the pathloss power offset for the first uplink component carrier y with respect to the second uplink component carrier x, and sending the calculated pathloss offset, deltaPL(y,x) to the UE.

A communication system includes a transmitting communication device (310) and a receiving communication device (320). The transmitting communication device (310) determines a control element, e.g., a control element of a Media Access Control protocol, associated with one of the carriers and provides the control element with an identifier specifying the carrier the control element is associated with. The transmitting communication device (310) sends the control element with the identifier on one of the carriers to the receiving communication device (320). The receiving communication device (320) receives the control element and determines, from the identifier received with the control element, the carrier the control element is associated with. Further, the receiving communication device (320) determines, on the basis of parameters indicated by the control element, a data transmission property of the carrier the control element is associated with.

The disclosure relates to a user equipment for a wireless communications system, and to a related method for identifying a resource to use for a transmission of control information on a physical uplink control channel, PUCCH, format 3. The method comprises receiving (610) a resource index from a serving radio base station, and identifying (620) the resource to use for the transmission of the control information in a subframe based on the received resource index, wherein the identified resource is within a same confined set of physical resource blocks regardless of if a normal or a shortened PUCCH format 3 is used in the subframe.

Methods and apparatus for organizing reception on a channel by a user equipment are disclosed. A method includes determining a channel group based on a first physical resource block index of a physical uplink shared channel and a cyclic shift of uplink demodulation reference signals, without an offset value; determining a channel sequence based on the first physical resource block index, the cyclic shift, and the offset value; and determining a reception resource according to the channel group and the channel sequence.

Methods, for use in a communications system, for transmitting information that applies a method for channel coding the CQI/PMI information, wherein a turbo coding method is applied when the size of the CQI/PMI information is above a first threshold value. The methods further include setting, based on the method applied for the channel coding, an offset value indicative of the difference in code rate between the code rate of the CQI/PMI information and the assigned code rate of the UL-SCH data information on the PUSCH. The methods also include determining, based on the offset value, the number of coded bits to be used for transmission of the CQI/PMI information, and transmitting the CQI/PMI information to a radio access network node on resources assigned based on the determined number of coded bits.

Methods and arrangements in a network node and mobile terminal, respectively, in a wireless communication system supporting aggregation of component carriers. The method in a network node involves, when resources on at least two downlink component carriers are being assigned to a mobile terminal at the same time, allocating (908) control information bits not related to power control in a bit field, which is normally used for power control in a message on a physical downlink control channel associated with one of said at least two downlink component carriers. The method in a mobile terminal involves, using control information bits not related to power control obtained from a bit field, which is normally used for power control in a message on a physical downlink control channel associated with one of said at least two downlink component carriers, for locating information related to downlink or uplink transmissions.
