Abstract: A first access node that is operating on a first TDD carrier having a first TDD configuration will determine that a second TDD carrier on which a proximate second access node is operating has a different, second TDD configuration, such that there is at least one time interval in which the first TDD carrier is downlink concurrently with the second TDD carrier being uplink. In response to at least this determination, the first access node will then transition to a mode in which, during the time interval, the first access node will operate with reduced transmission power on a frequency portion of the first TDD carrier that is closest in frequency to the second TDD carrier. Further, the first access node could allocate the lower-transmission-power frequency portion for use in transmission to served devices deemed to be in at least predefined threshold high quality coverage of the first access node.

Abstract: When access nodes provide collocated service on overlapping carriers with different subcarrier spacing than each other, at least one of the access nodes could be configured to cluster its respective allocation of air-interface resources at an end of the frequency-overlap region, and a single guard band could then separate that clustered resource allocation from the remainder of the frequency-overlap region in which the other access node could allocate resources. In an example implementation for instance, the access nodes could be configured to cluster their respective concurrent allocation of resources at different respective ends of the frequency-overlap region so as to help maximize frequency width between transmission in the frequency-overlap region on one of the carriers with one subcarrier spacing and transmission in the frequency-overlap region on the other carrier with the other subcarrier spacing.

Abstract: Methods and systems are provided herein for combining antenna signals based at least in part on the physical separation distance between antennas. A computing device includes a first antenna. The first the antenna is configured to receive a first signal. The first antenna is one of a plurality of antennas in the computing device. A second antenna is configured to receive a second signal. The second antenna has more physical separation distance from the first antenna relative to any other antenna within the computing device. A combiner within the computing device is configured to combine the first signal and the second signal based on the second antenna having more physical separation distance from the first antenna relative to any other antenna.

Abstract: Disclosed is a mechanism to help a user equipment device (UE) transmit multiple distinct bit streams concurrently to a base station with reduced risk of interference. The UE will orthogonally encode the multiple distinct bit streams using orthogonal binary codes to produce orthogonally encoded bit streams, and the UE will add the orthogonally coded bit streams together to produce a resulting bit stream and will transmit that resulting bit stream on an antenna path to the base station. Upon receipt of the transmitted bit stream, the base station could then apply the same orthogonal binary codes to the bit stream in order to extract the underlying multiple distinct bit streams.

Abstract: Disclosed are methods and systems for adjusting allocation of uplink (UL) and downlink (DL) air interface resources to user equipment devices (UEs) in a wireless communication system configured for dynamic allocation of relative amounts UL and DL time division duplex (TDD) air interface resources. The wireless communication system may determine usage demand for UL air interface resources relative to DL air interface resources as a function of time of day. Then, based on the usage demand, a schedule may be created for assigning a ratio of UL TDD allocation to DL TDD allocation. Finally, dynamic TDD allocation may be applied to set relative amounts of UL and DL air interface time for UEs served by the wireless communication system according to the schedule, instead of applying unscheduled dynamic TDD allocation of relative amounts of UL and DL air interface time.

Abstract: A mechanism to help facilitate uplink communication from multiple user equipment devices (UEs) to a base station on shared air interface resources, i.e., with the multiple UEs transmitting to the base station on the same subcarriers and at the same time as each other. The mechanism makes use of successive interference cancellation (SIC) and non-orthogonal coding to help distinguish and separate the UEs' transmissions from each other and thus to help the base station separately process each UE's transmission even though the UEs transmit to the base station on the same air interface resources as each other.

Abstract: Systems and methods are provided for improving uplink coverage in a wireless communication network. A first correlated array and a second correlate array each comprise a plurality of antenna elements. Each correlated array has an inter-element spacing of one wavelength of a signal for which the array is configured to receive. The first and second correlated arrays are interleaved such that one-half of a wavelength of a signal for which at least one of the correlated arrays is configured to receive separates adjacent elements of the first and second correlated arrays. Signals received by each correlated array are combined using statistical signal processing techniques to create combined signals that may be provided to the wireless communication network. Combining uplink signals from at least two interleaved uncorrelated arrays may increase the effective spacing of each array without sacrificing base station space or throughput.
