  • Patent number: 9635627
    Abstract: Various communication systems may benefit for techniques and devices for improved connection reliability and interference management. For example, communication systems of the long term evolution (LTE) of the third generation partnership project (3GPP) or LTE advanced (LTE-A) may benefit from systems and methods for improving connection reliability and managing interference created by beamforming. For example, a method may include preparing at least one interference-protected message to transmit. The method may also include transmitting the at least one interference-protected message preferentially on at least one physical resource block on which beamforming is not allowed.
    Type: Grant

  • Patent number: 8553594
    Abstract: A method and apparatus for performing resource allocation with lower required overhead is provided herein. Resource allocations for data transmissions are chosen in such a way as to provide channel quality information for various parts of the channel bandwidth (frequency selective channel quality information), such as allocating two different resource blocks (on different sets of subcarriers) to a mobile unit for two different transmissions. These data transmissions are used to estimate frequency selective channel quality information, thereby eliminating or greatly reducing the need for channel sounding with a broadband pilot. As a result, the overhead on the uplink of the communication system may be significantly reduced.

  • Publication number: 20120147813
    Abstract: During operation, the choice of the initial ranging code (sometimes referred to as a ranging preamble code, or a random-access preamble) at the mobile station is associated with a PMI feedback to be signaled to the base station during the initial ranging. More particularly, during initial system access a ranging code is transmitted by the mobile station to the base station. The mobile station chooses one of the available ranging codes based on the channel conditions and associates the ranging code with channel feedback information. The ranging code is then transmitted to the base station, and provides the base station with the channel feedback information.

  • Publication number: 20110216723
    Abstract: A method and apparatus are provided for indicating to a communication unit a plurality of modulation and coding schemes (MCSs) to be utilized for communication. During a first MCS is determined for first resource blocks to be sent to a first remote unit or base station, and a second MCS is determined for a second resource block to be sent to the remote unit or base station. A message is transmitted indicating the first and the second MCS and also indicating the first resource blocks and the second resource block. Finally, a first PDU is transmitted to the remote unit or base station at a first time using the first MCS and the first resource blocks and a second PDU is transmitted to the remote unit or base station at the first time using the second MCS and the second resource block.
