Abstract: Aspects described herein may enable a network entity to create an mmW cell geometry and/or to seed a base station codebook and a UE codebook to improve a beamforming procedure while maintaining peak performance gain that is provided by scanning narrower beams. The network entity may provide information associated with the base station codebook and the UE codebook to the base station. The network entity may also provide, to the base station, a subframe structure to be used during a beamforming procedure that is based on the base station codebook and the UE codebook. The base station and the UE may perform the beamforming procedure based in the subframe structure using beam orientations indicated in the base station codebook and the UE codebook. From the beamforming procedure, the base station and the UE may determine an access beam to be used in communication between the base station and the UE.

Abstract: Methods, systems, and devices for wireless communication are described. A network server may configure a base station for beamforming communications based on a service type of data used by a user equipment (UE). The network server may determine the service type of the data based on position data of the UE, along with other statistical information related to data usage. The position information may include global position system (GPS) information, gyroscope information, accelerometer information, or information related to the UE's subarray geometry. The base station may receive the position information from the UE and convey it to the network server. The network server may use the position information to generate a network map and to identify the service type of communication.

Abstract: Low complexity, high order multiple input, multiple output (MIMO) operations are described in which a user equipment (UE), configured with at least one normal performance receiver chain and at least one low-performance, low-complexity diversity receiver chain, signals a capabilities indicator identifying existence of the low-performance diversity receivers. Using the UEs capabilities, a serving base station may schedule uplink and downlink transmissions for the UE to reduce uplink-downlink collisions below a minimum threshold number. The serving base station may also take UE transmit power into consideration for signaling power control or modulation and coding schemes in order to minimize potential interference cause by UE transmissions. For channel state feedback, the UE may provide different channel feedback for uplink-downlink collision subframes and non-collision subframes.

Abstract: An electronic circuit is provided. The electronic circuit includes a first port, a second port, a first path coupled between the first and second ports, and a second, alternative path coupled between the first and second ports. The electronic circuit also includes at least one tunable circuit element shared between the first and second, alternative paths. The first path includes a delay line with a length selected to match at least one characteristic of the first path with a corresponding characteristic of the second path within a selected tolerance.
