Abstract: 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,n HARQ) 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-?F_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.

Abstract: A wireless network association and authentication system includes an access point that is coupled to an authentication server via a first wireless network. The access point receives, from a first user device that associates with the access point, a first request for access to a second wireless network provided by the access point that is coupled to a wide area network through the first wireless network. The first request includes first authentication information. The access point provides the first request that includes the first authentication information to the authentication server via the first wireless network and receives a first authentication response from the authentication server via the first wireless network. In response to the first authentication response indicating that the first user device is authenticated, the access point provides the first user device access to the second wireless network.

Abstract: It is possible to improve the CQI reception performance even when a delay is caused in a propagation path, a transmission timing error is caused, or a residual interference is generated between cyclic shift amounts of different ZC sequences. For the second symbol and the sixth symbol of the ACK/NACK signal which are multiplexed by RS of CQI, (+, +) or (?, ?) is applied to a partial sequence of the Walsh sequence. For RS of CQI transmitted from a mobile station, + is added as an RS phase of the second symbol and ? is added as an RS phase of the sixth symbol. A base station (100) receives multiplexed signals of ACK/NACK signals and CQI signals transmitted from a plurality of mobile stations. An RS synthesis unit (119) performs synthesis by aligning the RS phase of CQI.
