摘要： The disclosure relates to methods and devices for performing uplink power control in a radio communication system. An example method comprises a step of receiving, at a user equipment (UE) a transmit power control (TPC) command. The method also comprises, if the UE does not have an uplink transmission scheduled for a subframe associated with the TPC command, a step of accumulating, by the UE, the TPC command with previously received TPC commands based on whether the UE has reached a maximum transmit power or a minimum transmit power in a reference format for a Physical Uplink Shared Channel (PUSCH), Sounding Reference Signal (SRS) or Physical Uplink Control Channel (PUCCH) transmission. Thus the UE is enabled to receive TPC commands while the UE is not transmitting anything in the uplink.

摘要： A method of operating a wireless communication terminal includes receiving one or more downlink control messages that each contain scheduling information scheduling the wireless terminal to receive a downlink transmission on either a primary carrier or a secondary carrier. The method also includes determining, for each of the downlink control messages, whether that message includes scheduling information for the primary carrier or for a secondary carrier. Additionally, the method includes selecting a format for an uplink control message based on whether any of the downlink control messages includes scheduling information for a secondary carrier, generating an uplink control message based on the selected format, and transmitting the uplink control message to the base station.

摘要： The invention relates to random access procedures in an LTE-system applying carrier aggregation, in particular to support network-initiated random access on secondary cells. A UE transmits a preamble on a random access channel to a radio base station on a secondary cell and receives or detects a random access response message from the base station including timing advance information for uplink transmission by the UE. The UE can determine the secondary cell that the control information in the random access response message refers to and transmits to the base station based on the timing advance information in the random access response message.

摘要： A system and method for determining a Physical Uplink Control Channel (PUCCH) power control parameter h(nCQI,nHARQ) for two Carrier Aggregated (CA) PUCCH formats—PUCCH format 3 and channel selection. The value of h(nCQI,nHARQ) may be based on only a linear function of nHARQ for both of the CA PUCCH formats. Based on the CA PUCCH format configured for the User Equipment (UE), the e-Node B (eNB) may instruct the UE to select or apply a specific linear function of nHARQ as a value for the power control parameter h(nCQI,nHARQ), so as to enable the UE to more accurately establish transmit power of its PUCCH signal. Values for another PUCCH power control parameter—ΔF—PUCCH(F)—are also provided for use with PUCCH format 3. A new offset parameter may be signaled for each PUCCH format that has transmit diversity configured
