Abstract: Methods, systems, and devices for wireless communications are described. A first device may monitor for a set of reference signals from a second device using a set of directional beams. The first device may perform measurements on the received reference signals and select a subset of directional beams from the set of directional beams based on the performed measurements. Each directional beam may be associated with a set of beamforming weights. The first device may communicate with the second device using a dynamic set of beamforming weights. The first device may form the dynamic set of beamforming weights using a combination of beamforming weights from each set of beamforming weights associated with the subset of directional beams. The dynamic set of beamforming weights may be different from each set of beamforming weights associated with the subset of directional beams.

Abstract: Methods, systems, and devices for wireless communication are described. In some systems, a wireless device may detect, using a sensor at the wireless device, one or more locations at which human tissue may be present within a coverage area of the sensor. The wireless device may select, from a set of beams, a beam and a corresponding transmit power. The wireless device may select the beam and the corresponding transmit power based on the detection of the one or more locations at which the human tissue is present within the coverage area of the sensor and a radio frequency coverage area of the beam. The wireless device may transmit uplink data using the selected beam and the selected transmit power.

Abstract: Methods, systems, and devices for wireless communication at a user equipment (UE) are described. A UE may establish a wireless connection with a primary cell and may identify a set of antenna modules of the UE and multiple sets of receive beams. Each set of receive beams may include at least one beam from each antenna module. The UE may perform a measurement procedure on signals received from one or more candidate secondary cells using at least a first set of receive beams. The UE may then transmit, to the primary cell, a measurement report based on performing the measurement procedure upon determining that at least one of the multiple sets of receive beams satisfies a threshold value and before performing the measurement procedure on signals received from the one or more candidate secondary cells using at least one remaining set of receive beams.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit, and a user equipment (UE) may receive a group physical control channel signaling, which may configure grant uplink transmissions for a set of UEs including the receiving UE. The group physical control channel signaling may indicate allotted resources for configured grant uplink transmissions. The group physical control channel signaling may further indicate a group physical control channel which a UE may monitor for control messages. The UE may transmit a configured grant uplink transmission in accordance with the group physical control channel signaling. The base station may receive the configured grant uplink transmission and may determine a control message which it may transmit in the group physical control channel based on the configured grant uplink transmission. The UE may receive the control message, and may determine whether to retransmit a configured grant uplink transmission based thereon.

Abstract: Techniques and apparatus for channel mapping in shared spectrum in the presence of higher tier users are provided. One technique includes evaluating, for different channel locations of orthogonal channel(s) within available spectrum, an amount of transmission limitation imposed to a group of devices due to incumbent protection, an amount of available bandwidth, and/or a maximum contiguous channel size. A channel location is assigned to each orthogonal channel, based on the evaluation. Another technique includes determining first channel location(s) in order to assign at least a first orthogonal channel within available spectrum. Each first orthogonal channel is associated with a group of devices sharing bandwidth within one or more networks. An exchange is participated in with a network entity to share a first set of information associated with the first channel locations. A determination is made whether to modify portion(s) of the first set of information, based on the exchange.

Abstract: Described herein are aspects related to assigning primary channels in wireless communications. An amount of available bandwidth within a radio frequency band can be determined for shared access by a plurality of operators, where each operator operates a radio access network having one of a plurality of radio communication compatibility types, and where each radio communication compatibility type defines a set of one or more compatible radio access technologies. The amount of available bandwidth can be allocated into radio compatibility type-specific bandwidth partitions for each radio communication compatibility type based on a number of the plurality of radio communication compatibility types and a number of the plurality of operators corresponding to each radio communication compatibility type. A primary channel can be assigned within at least one of the radio compatibility type-specific bandwidth partitions to at least one operator of the number of the plurality of operators.
