The network planning process seeks diversity in customer location assignments by creating additional capacity through the re-assignment of customer locations to alternate network nodes in order to free up space on network nodes needed to off-load customer locations from other over-loaded network nodes. The network planning process permits an expanded ring of network nodes to accommodate dense customer traffic load across a wide area while meeting both individual connection and overall system requirements. | 2010-06-17 |

A mobile station performs a recursive process to update channel estimates of interfering channels on a symbol-by-symbol basis for use in canceling interference from data subcarriers received through two or more antennas. | 2010-06-17 |
20100150080 | METHODS AND APPARATUS FOR REUSE OF A WIRELESS RESOURCE - Methods and apparatus related to reuse of a wireless resource are described. Various methods and apparatus are well suited to wireless communications systems lacking centralized control, e.g., an ad hoc peer to peer wireless communications system. A wireless device, corresponding to a second connection, evaluates whether or not it can reuse a resource associated with a first connection. The first connection is, e.g., an existing active connection and the second connection is, e.g., a potential connection. The wireless device receives one or more control signals from one or more first connection devices. The wireless device determines, based on the received control signals, one or more estimated SINRs characterizing expected results in the system if the two connections should use the same resource concurrently. The wireless device makes a resource reuse decision based on the determined estimated one or more SINRs and a threshold criteria. | 2010-06-17 |
