20110243009 | Physical Downlink Shared Channel Muting on Cell-Specific Reference Symbols Locations for of Non-Serving Cells - The primary serving base station transmits PDSCH with zero energy on the inter-cell CRS resource element location. This is called mute PDSCH. Within the first Physical Resource Block (PRB | 10-06-2011 |
20110243079 | Transmission Modes and Signaling for Uplink MIMO Support or Single TB Dual-Layer Transmission in LTE Uplink - This invention is a method of wireless telephony. A bases station configures a user equipment for single-antenna port or multi-antenna port operation via Radio Resource Control (RRC) signaling including a 5-bit MCS-RV and 1-bit NDI for the second codeword (CW1) are needed for the DCI format 4. | 10-06-2011 |
20120063321 | CFI Signaling for Heterogeneous Networks with Multiple Component Carriers in LTE-Advanced - This invention mitigates interference in wireless telephony in heterogeneous networks having a macro base station and a low power base station. This invention attempts to avoid cross carrier scheduling on an anchor carrier and a non-anchor carrier. If cross carrier scheduling is unavoidable, then this invention attempts: (1) semi-statically signalling a CFI value on a cross-scheduled component carrier; (2) semi-statically signalling a channel quality information (CSI) value on a cross-scheduled component carrier setting a Physical Hybrid ARQ Indicator CHannel (PHICH) value to be maximum; or (3) semi-statically signalling a channel quality information (CSI) value on a cross-scheduled component carrier using Physical Control Format Indicator CHannel (PCFICH) power boosting on cross-scheduled component carriers (CC). | 03-15-2012 |
20120182857 | Sounding Reference Signal Processing for LTE - A wireless communication receiver including a serial to parallel converter receiving an radio frequency signal, a fast Fourier transform device connected to said serial to parallel converter converting N | 07-19-2012 |
20120220286 | Periodic Channel Quality Indicator on Physical Uplink Control Channel for Carrier Aggregation - This application considers the need for enhancements to the baseline CSI reporting mechanisms including maximum payload size, CQI/PMI reporting configurations and CSI transmission in the event of collision between CSI reports from different CCs. | 08-30-2012 |
20130077574 | Resource Allocation and Signaling for Aperiodic Sounding - This patent application considers the configuration aperiodic sounding reference signal parameters by radio resource control signaling and the triggering of aperiodic SRS transmission by detection of a positive trigger in downlink control information. Transmission timing rules are also proposed to determine the valid subframes for aperiodic SRS transmission. | 03-28-2013 |
20130201921 | Carrier Indication In a Bandwidth Aggregated Wireless Communications Systems - In this invention wireless communication of data between a user equipment and a base station including bandwidth aggregation of a plurality of component carriers, includes a first unit transmitting on a first component carrier a grant control signal the other unit specifying a second component carrier different to transmit the typically via a carrier indication field of 3 bits. The carrier indication field can be a one-to-one mapping to each possible second component carrier of a component carrier offset from an anchor carrier, which could be the first component carrier. | 08-08-2013 |
20130258886 | METHOD AND APPARATUS FOR CHANNEL STATE INFORMATION FEEDBACK IN A COORDINATED MULTI-POINT COMMUNICATION SYSTEM - A method of operating a wireless communication system (FIG. | 10-03-2013 |
20140036737 | UPLINK SIGNALING FOR COOPERATIVE MULTIPOINT COMMUNICATION - A method of operating a wireless communication system is disclosed (FIG. | 02-06-2014 |
20140036859 | Methods to Increase Sounding Capacity for LTE-Advanced Systems - This invention is a method of wireless communication between a base station and at least one user equipment. The base station signals a user equipment to produce a burst of a number of sounding reference signals having a predetermined burst duration. The user equipment sounds wireless channel to the base station via a burst of sounding reference signals having the predetermined burst duration. The base station schedules transmission of user equipment in time and frequency domain according to a CQI estimated from the received sounding reference signals. | 02-06-2014 |
