20140241242 | METHODS AND APPARATUS FOR CHANNEL SOUNDING IN BEAMFORMED MASSIVE MIMO SYSTEMS - Base station (BS) and mobile station (MS) methods and apparatus are provided. The BS configures an uplink sounding channel made up of at least one OFDM symbol in an uplink slot. The BS signals to the MS use and location of different configurations of the uplink sounding channel via a system configuration broadcast message. The uplink sounding channel comprises OFDM symbols where one or more of a subcarrier spacing and a sampling frequency is different from that of OFDM symbol used for data transmission. Each OFDM symbol comprises a sounding reference symbol corresponding to at least one transmit beam and is received by at least one receive beam to form at least one transmit-receive beam pair. The at least one transmit-receive beam pair for UL-SRS in different OFDM symbols are different. The sounding channel configuration is based on information received from neighboring BSs via inter-BS coordination over a pre-defined interface. | 08-28-2014 |
20150036571 | TRANSMISSION AND SCHEDULING SCHEMES FOR WIRELESS FRONTHAUL - A communication system includes a plurality of eNodeBs (eNBs) configured to serve one or more user equipments (UEs). The plurality of eNBs includes a first eNB and a second eNB. The first eNB is configured to wirelessly communicate on a resource with the second eNB. The resource includes a time resource and/or a frequency resource. The first and second eNBs are configured to cooperatively serve the one or more UEs. The first and second eNBs are configured to engage in wireless communication following a predetermined schedule known to the plurality of eNBs. | 02-05-2015 |
20150208378 | METHOD AND APPARATUS FOR REDUCING ACCESS OVERHEAD FROM PAGED DEVICE IN MACHINE TO MACHINE COMMUNICATION SYSTEM - An apparatus for an idle mode terminal is configured to perform a method for operating the idle mode terminal in a Machine to Machine (M2M) communication system. A paging message is received from the base station during a paging listening interval. The Apparatus determines whether an indicator indicating receipt of multicast group data is included in the paging message. When the indicator indicating the receiving of multicast group data is included, data transmitted via a downlink resource that uses an identifier mask of a multicast group to which a terminal belongs is received. Thereafter, a paging non-listening interval is entered. | 07-23-2015 |
20150373587 | METHODS FOR BANDWIDTH EFFICIENT OPERATIONS IN WIRELESS LOCAL AREA NETWORKS - A method of establishing a data transmission bandwidth between a transmitting node and a receiving node is provided. The method includes sending a request to send (RTS) message from a transmitting node to a receiving node, the RTS message indicating a data transmission bandwidth to be considered for use in subsequent data transmission and establishing a negotiated data transmission bandwidth comprising multiple channels, wherein each channel comprises a 20 MHz bandwidth, and wherein the multiple channels are at least one of contiguous and non-contiguous in frequency. | 12-24-2015 |
20160080115 | METHODS FOR EFFICIENT ACKNOWLEDGEMENT IN WIRELESS SYSTEMS - An AP receives, from one or more STAs, an uplink orthogonal frequency division multiple access based block acknowledgement response in an 802.11 based wireless network. The AP transmits the downlink allocation for the downlink frame to the plurality of mobile devices, wherein the order of the plurality of mobile devices in the downlink allocation indicates respective uplink resource assignments. The STA receives a downlink frame with an allocation comprising the listing of a plurality of mobile devices for which data is transmitted in the downlink frame. The STA identifies an uplink resource allocation as a function of a location of a first mobile device within the listing of the plurality of mobile devices. The STA then transmits an acknowledgment on the uplink resource allocation corresponding to the location of a first mobile device within the listing of the plurality of mobile devices. | 03-17-2016 |
