20110170498 | METHOD AND SYSTEM FOR ENABLING RESOURCE BLOCK BUNDLING IN LTE-A SYSTEMS - A base station is provided. The base station includes a transmit path circuitry to transmit an indication of whether a subscriber station is configured with precoding matrix indicator/rank indicator (PMI/RI) reporting. The transmit path circuitry sets a pre-coding granularity to multiple physical resource blocks in the frequency domain to perform a same pre-coding over a bundled resource block if the subscriber station is configured with PMI/RI reporting. The bundled resource block includes multiple consecutive physical resource blocks in the frequency domain. The base station also includes a receive path circuitry to receive feedback from the subscriber station. | 07-14-2011 |
20110255505 | SYSTEMS AND METHODS FOR BUNDLING RESOURCE BLOCKS IN A WIRELESS COMMUNICATION SYSTEM - A base station for use in a wireless network operable to communicate with a plurality of mobile stations. The base station transmits a downlink frame to a first mobile station. The downlink frame comprises time-frequency resource elements allocated in a plurality of physical resource blocks. The base station transmits the plurality of physical resource blocks in bundles having a bundle size that is a function of the system bandwidth configuration and the base station uses the same precoder for all physical resource blocks in the same bundle. The bundle size is from one physical resource block to three physical resource blocks. | 10-20-2011 |
20120003945 | SYSTEMS AND METHODS FOR 8-TX CODEBOOK AND FEEDBACK SIGNALING IN 3GPP WIRELESS NETWORKS - A mobile station for use in a wireless network. The mobile station is operable to transmit feedback values to a base station of the wireless network. The feedback values include a first precoder matrix indicator (PMI1) value and a second precoder matrix indicator (PMI2) value. The mobile station transmits the PMI2 value to the base station in the same subframe as a channel quality indicator (CQI) value. The CQI value may be either a wideband CQI value or a subband CQI value. | 01-05-2012 |
20120026972 | APPARATUS AND METHOD FOR SUPPORTING RANGE EXPANSION IN A WIRELESS NETWORK - A wireless network for communicating with a mobile station capable of operating in a range expansion mode. The wireless network comprises a macro-base station (BS) operable to communicate with the mobile station and a micro-base station (BS) in a coverage area associated with the macro-BS. The macro-BS transmits to the micro-BS a first control message indicating a range expansion (RE) capability of the mobile station. In response, the micro-BS transmits to the macro-BS PCFICH information associated with the micro-BS. The macro-BS transmits the PCFICH information to the mobile station and the mobile station uses the PCFICH information to perform a handover procedure to the micro-BS. | 02-02-2012 |
20120069917 | SYSTEM AND METHOD FOR PUCCH SUBBAND FEEDBACK SIGNALING IN A WIRELESS NETWORK - A mobile station for use in a wireless network. The mobile station transmits feedback reports to a base station of the wireless network. The feedback reports comprise a first feedback report, a second feedback report and a third feedback report. The first feedback report includes a precoder type indication (PTI) value that indicates at least one of a period of the second feedback report and a period of the third feedback report. The PTI value indicates a ratio of the second feedback report period to the third feedback report period. The PTI value also indicates the selected feedback information contained in the second feedback report and the third feedback report. | 03-22-2012 |
20120083280 | METHODS AND APPARATUS FOR ENABLING INTERFERENCE COORDINATION IN HETEROGENEOUS NETWORKS - For use in a heterogeneous network, a method for enabling interference coordination includes, upon occurrence of a trigger condition, determining, at a first low power node, that the first low power node is approaching a second low power node. The method also includes sending, at the first low power node, an entering message to an evolved Node-B (eNB) that serves the first low power node. The method further includes receiving, at the first low power node, configuration information from the eNB to perform at least one measurement of the second low power node. | 04-05-2012 |
20120201207 | APPARATUS AND METHOD FOR PERIODIC CHANNEL STATE REPORTING IN A WIRELESS NETWORK - Channel State Information (CSI) is reported by a subscriber station to a base station. The CSI is reported periodically for at least two physical uplink control channels (PUCCH). In case of a collision between a report for a first PUCCH and a report for the second PUCCH, each of the report types is partitioned into one of a number of classes, which include: a first class for rank indicator related report types and wideband (WB) W1 report types; a second class for WB report types or WB channel quality indicator report types; and a third class for subband related report types or W1 report types. A priority rule assigns a priority to each of the classes. The CSI feedback reports are transmitted according to the priority rule such that the report type included in a higher class is transmitted and the report type included in the lower class are dropped. | 08-09-2012 |
