Said method comprises: causing, by an apparatus, transmission of a request for space-time channel sounding to at least one unassociated access node; receiving, in the apparatus as a multi-antenna transmission and in response to said request, at least one message comprising space-time sounding information from at least one unassociated access node; determining, by the apparatus, at least one parameter describing space-time channel quality from the received space-time sounding information; and causing, by the apparatus, transmission of the at least one determined parameter to an associated access node or causing selection of an unassociated access node for further communication based at least partly on the determined at least one parameter. | 2014-12-18 |
20140369436 | PRECODING MATRIX INDICATOR (PMI) INFORMATION TRANSMISSION METHOD AND DEVICE - Disclosed are a precoding matrix indicator (PMI) information transmission method and device, for realizing the feedback and receiving of PMIs. The PMI information feedback method provided in the present application server includes: UE determining the feedback of a PMI and a feedback mode used for feeding back the PMI; the UE determining a rank indicator (RI) and a precoding matrix in a compressed precoding matrix set and determining an RI and first PMI combined coding information value according to a preset RI and first PMI combined coding information value and a correlation list of RIs and codebook indices; and the UE employing the feedback mode to send the determined RI and first PMI combined coding information value to a base station. | 2014-12-18 |
20140369437 | RECEIVER DEVICE, TRANSMITTER DEVICE, RECEPTION METHOD, AND TRANSMISSION METHOD - Provided is a receiver device that can switch between transmission methods, while minimizing increase in the number of blind decryption iterations and the amount of signaling needed for acknowledgement.

20140369438 | Methods and Apparatus for Overlapping MIMO Physical Sectors - A system for communicating with wireless devices. The systems includes radio groups whose MIMO physical sectors overlap. The MIMO physical sectors communicate using different channels. The MIMO physical sectors overlap to form an area of overlap. Each radio group includes directional antennas and radios. Radios are selectively coupled to the antennas. The antennas that are oriented so that the physical sectors of the antennas overlap to operate as MIMO antennas and form the MIMO physical sector for the radio group. The antennas operate as a MIMO antenna. | 2014-12-18 |
