    Abstract: A physical channel processor on a wireless device and method for precoding for spatial multiplexing in an open-loop multiple-input multiple-output (MIMO) mobile communication system is disclosed. The method comprises the operation of receiving an input vector block from a layer mapper. The input vector block includes user equipment-specific reference signals (UE-RSs) or data in a physical downlink shared channel (PDSCH). The operation of generating a large delay cyclic delay diversity (CDD) vector block from the input vector block using a precoder configured for large delay CDD on an antenna port follows. The data can be resource element mapped with UE-RSs or channel-state information reference signals (CSI-RSs) in a physical resource block (PRB).

    Abstract: Embodiments of a system and method for transmitting data from an access point in a multiple user multiple input multiple output (MU-MIMO) system are provided. A first indication of signal quality (ISQ) is received at the access point from a first station and a second ISQ is received from a second station. The access point sets a first power level and a first modulation and coding scheme (MCS) for transmission of a first aggregated media access control (MAC) protocol data unit (A-MPDU) to the first station as a function of the first ISQ and an amount of payload data corresponding to the first A-MPDU. The access point also sets a second power level and a second MCS for transmission of a second A-MPDU as a function of the second ISQ and an amount of payload data corresponding to the second A-MPDU.

    Abstract: In some embodiments a beamforming method is disclosed. The method can include transmitting a beam having a channel defined by a maximum ration transmission vector (MRT) and receiving a first response from a receiver, where the first response has first information such as parameters related to the transmitted beam. Using the parameters and the initial MRT another directional transmission can be made. A similar process can determine a maximum combining ratio for a receiver. Set up communications between the transmitter and the receiver can be reduced by omitting data from transmission that can be acquired by other means such as from memory or calculations. Additional embodiments are also disclosed.

    Abstract: In a wireless communication network, specific portions of the communication may combine directional transmission with omnidirectional reception. In particular, sector- level directional transmission may be established through sector sweeps, followed by antenna training for more directionality. In some embodiments, collisions during the exchange may be reduced by having different network devices use different sub-channels or different time slots. In some embodiments, each network may restrict its network communications to a single sub-channel that is different than the sub-channels used by adjacent networks.
