A plurality of distributed transceivers in a mobile entity such as a car, a truck, an omnibus (bus), a trailer, a mobile home, train, bus, a forklift, construction equipment, a boat, a ship, and/or an aircraft, and/or one or more corresponding antenna arrays that are communicatively coupled to the distributed transceivers are configured to handle communication of one or more data streams among one or more of a plurality of wireless communication networks, one or more other mobile entities and/or one or more mobile communication devices. The data streams may be communicated utilizing the configured one or more of the plurality of distributed transceivers and/or the one or more corresponding antenna arrays. The wireless communication networks includes a satellite network, a wireless wide area network, a wireless medium area network, a wireless local area network, a wireless personal area network, a network cloud and/or the Internet.

The present application relates to an indication method for transmitting a physical control channel. The method includes: determining, by a radio node, one of space frequency block coding SFBC transmission and single frequency transmission, as a receiving mode used by user equipment to receive a downlink physical control channel; and sending, by the radio node, an indication message to the user equipment, where the indication message is used to instruct the user equipment to receive, in the receiving mode, the downlink physical control channel sent by the radio node. The user equipment receives the downlink physical control channel according to the receiving mode, thereby improving system performance.

A technique for improving wireless communication characteristics involving matching transmitter antenna patterns to receiver antenna patterns. In a specific implementation, the transmitter antenna pattern adapts to changing parameters, such as when a smartphone is initially held in a first orientation and is later held in a second orientation. Because the transmitter antenna patterns match the receiver antenna patterns, signal quality between stations improves. In some implementations, antennas are organized and mounted to maximize spatial diversity to cause peak gains in different directions.

Techniques are presented herein for computing angle-of-arrival estimates while switching antenna states during a packet unit for the general Orthogonal Frequency Division Multiple Access (OFMDA) case (including a single user). A wireless device computes channel estimates throughout the entire frame and not only during the training symbols. Consequently, the wireless device computes channel estimates for all antennas in its array within a single frame instead of having to wait for multiple frames.

A wireless communication device may autonomously transition from a multiple antenna port mode to a single antenna port mode. The wireless communication device may implicitly notify a base station about the autonomous transition from the multiple antenna port mode to the single antenna port mode. The base station may reallocate resources that were previously allocated to the wireless communication device but that are no longer being used by the wireless communication device. In some cases, the base station may configure the wireless communication device's antenna port mode via radio resource control signaling.

Disclosed herein are apparatuses and a method for improving wireless communication characteristics by matching transmitter antenna patterns to receiver antenna patterns. An embodiment operates by generating a station profile for each of a plurality of stations based on a structure of each of the plurality of stations and an antenna pattern group of each of the plurality of stations. The embodiment then identifies a station profile of a first station from among the plurality of stations based on information received from the first station. Finally, the embodiment searches for an antenna pattern for the first station using the antenna pattern group corresponding to the station profile.

A wireless communication system with scalable diversity and multi-transceiver diversity deployment is disclosed. An example communication system includes a first wireless transceiver, having a first bandwidth and a first center frequency, a second transceiver, having a second bandwidth and a second center frequency, and a processor. The processor is configured to operate the wireless communication system in a first mode when a difference between the first center frequency and the second center frequency is greater than or equal to half of the first bandwidth plus the second bandwidth. The processor is also configured to operate the wireless communication system in a second mode when a difference between the first center frequency and the second center frequency is less than half of the first bandwidth plus the second bandwidth.

A multiple-input multiple-output (MIMO) wireless transceiver with N transmit and receive chains and a bandwidth evaluation circuit, a chain partitioning circuit and a switchable radio frequency RF filter bank. The bandwidth evaluation circuit evaluates both the utilization of the WLAN(s) and any remaining communications channels and determines whether to operate the MIMO chains synchronously as a single radio or asynchronously as multiple radios. The chain partitioning circuit either partitions subsets of the MIMO chains for asynchronous operation as distinct radios or combines all MIMO chains for synchronous operation as a single radio. The switchable RF filter bank is responsive to a partitioning of subsets of the chains into distinct radios to add RF filters to a RF portion of the chains to isolate each radio from one another, and responsive to a combining of all MIMO chains into a single radio to remove all RF filters.
