Systems and methods for beamforming include a device including at least one of a head wearable display (HWD) or a console. The device establishes a first connection between an active HWD radio-frequency integrated circuit (RFIC) and an active console RFIC. The device compares a modulation and coding scheme (MCS) of the first connection to an MCS threshold. The device performs MCS measurements for a second connection of at least one of an idle HWD RFIC or an idle console RFIC, while the first connection is maintained, in response to the MCS not satisfying the MCS threshold. The device compares the MCS measurements of the second connection to the MCS threshold. The device switches to the second connection when at least one of the one or more MCS measurements satisfies the MCS threshold and/or above the MCS of the first connection.

System and method for uplink precoding in a communication system. In one embodiment, an apparatus is operable in a communication system and includes processing circuitry configured to identify an antenna element of a user equipment to disregard for uplink precoding, and provide an instruction to direct the user equipment to remove an antenna port associated with the antenna element from a codebook employed by the user equipment to precode a communication within the communication system.

Embodiments of an apparatus of a user equipment (UE) configured for operation in a fifth-generation system (5GS) are described herein. The UE comprises first and second array antennas for transmission of mmWave signals including a sounding-reference signal (SRS). In response to decoding radio-resource configuration (RRC) signalling that indicates antenna switching for SRS, the UE initiates a countdown timer and transitions the second array antenna from a low-power state to an active state. If a downlink control information (DCI) indicating SRS antenna switching is not received while the countdown timer is active, the UE generates a command to transition the second array antenna to a low-power state upon expiration of the countdown timer.

Wireless communication devices have antennas, and the antennas have earth-orientations. The wireless devices exchange network signaling with a wireless access node over the antennas. Some of network signaling indicates Device-to-Device (D2D) communication times and frequencies. The wireless communication devices exchange device signaling with each other over the antennas using the D2D communication times and frequencies. Some of the device signaling indicates the earth orientations for the antennas. The wireless communication devices select a subset of the antennas based on the earth orientations. The wireless communication devices exchange user data with each other over the selected subset of antennas using the D2D communication times and frequencies.

Systems and methods for providing improved cell-edge antenna performance are disclosed. The system can use various signal quality indicators (SQIs) for each user equipment (UE) on a particular wireless base station (WBS) or network. When one or more of these metrics reaches a first predetermined value for a particular UE, the WBS or the UE can decide to activate a diversity receive (Rx) antenna on the UE to improve reception. If one or more of these metrics continues to degrade to a second predetermined value, however, the WBS or the UE can deactivate the diversity Rx antenna and activate a primary Rx antenna. Deactivating the diversity antenna when signal quality/strength is poor can improve reception by reducing interference between the diversity Rx antennas. Disabling the diversity Rx antenna when signal quality/strength is poor can also decrease the number of retransmission requests from each UE, reducing traffic on the WBS.

A method includes: controllably configuring at least one antenna diversity switch in a wireless device to establish conductive paths between at least one transceiver of the wireless device and multiple antennas each disposed at a respective one of a multiple areas of a housing of the wireless device; and routing signals between the at least one transceiver and the multiple antennas, via the at least one antenna diversity switch, such that a signal is routed to either of at least two of the multiple antennas disposed at a first end area of the multiple areas of the housing of the wireless device or to either of at least two other antennas disposed at a second end area of the multiple areas of the housing of the wireless device.

Various embodiments disclosed herein provide for a beam recovery when there has been a partial control channel failure. Transient obstructions, and other interference effects can cause the failure of a beam pair link which can comprise a transmit beam and a receive beam associated with respective antennas on a transmitter and receiver. A group of control channels (downlink control channels) (configured as a control resource set CORESET) on a group of beam pair links can be associated with a group of uplink control resources (Physical Uplink Control Channel resources). When a subset of the CORESET group fails, the user equipment (UE) device can find another PUCCH that is associated with a working CORESET to send an indication to the network about the failure. When the network receives the indication, the network can switch the failed CORESET to a new beam pair link.
