On the other hand, the receiver determines a receive antenna weighting coefficient matrix based on the received training signals. | 2012-11-08 |
20120281662 | Scheduling Information of Overlapping Co-Scheduled Users in an OFDMA-MU-MIMO System - A user equipment (UE) used in a multi-user (MU)-multiple input multiple output (MIMO) orthogonal frequency division multiple access (OFDMA) system is disclosed. The UE includes a receiving unit to receive from a base station an indication of an estimate of or an upper-bound on the total number of MU-MIMO user equipments (|S|) that are scheduled on a sub-band by the base station, wherein the sub-band includes one or more resource units, a calculation unit to calculate channel quality based on the indication of the estimate of or the upper-bound on the total number of MU-MIMO user equipments, and a transmission unit to transmit to the base station an indication of the channel quality. Other methods and apparatuses also are disclosed. | 2012-11-08 |
20120281663 | METHOD, DEVICE AND SYSTEM FOR ASSIGNING ACK CHANNELS TO USERS - A method for assigning acknowledgement (ACK) channels to a user is used to feed back ACKs of a plurality of downlink sub-frames in one uplink sub-frame. According to the method, reserved ACK channels are divided into blocks according to the number of downlink sub-frames; each downlink sub-frame corresponds to one block; each block is divided into several sub-blocks; control channel element (CCE) sets within the same sub-frame are respectively mapped to different sub-blocks; and the ACK channels are assigned to the downlink sub-frames according to a sequence of increasing a mapping label d first and then increasing a sub-block label m. Thus, more unused ACK channels can be released to form resource blocks (RBs) for transmission on other channels, for example, for PUSCH transmission. Other methods for assigning ACK channels to a user, a device for assigning ACK channels to a user, and a communication system are further provided. | 2012-11-08 |
20120281664 | TELECOMMUNICATIONS - In a MIPv6 network, a mobile home agent (MHA) in a foreign network (FN) acts as an intermediate node between a mobile node (MN) and a correspondent node (CN) and allocates itself a secondary care-of address (SCoA) different from the care-of address (CoA) of the mobile node (MN), with a one-to-one relationship between the secondary care-of address (SCoA) and the home address (HAddr) of the mobile node. | 2012-11-08 |
20120281665 | WIRELESS COMMUNICATION SYSTEM, WIRELESS COMMUNICATION SETTING METHOD, BASE STATION, MOBILE STATION, AND PROGRAM - A wireless communication system including a base station and a mobile terminal, includes a setting unit to set a number of sets of at least one or more resource blocks for the mobile terminal, the at least one or more resource blocks of each set being consecutive in frequency. An allocation unit allocates the resource blocks for a transmission channel so that the resource blocks are not contiguous in frequency. A controller generates a reference signal sequence corresponding to a bandwidth of the allocated resource blocks, and maps the reference signal sequence to subcarriers according to an allocation of the resource blocks. | 2012-11-08 |
