    Abstract: A receiving device may remain in omni-directional mode while receiving RTS messages from transmitting devices. Multiple devices may transmit RTS messages at the same time, causing interference and preventing intended recipients of the RTS messages from transmitting a CTS message. To increase medium reuse, RTS may be transmitted and received in a slotted and directional manner. A receiving device may select a sweeping pattern for receiving transmission from neighboring devices. The receiving device may also determine one or more time slots allocated to each of the neighboring devices for receiving transmissions from the neighboring devices. The receiving device may transmit an indication of the sweeping pattern and the time slots to one or more of the neighboring devices. Subsequently, during one of the indicated time slots, the receiving device may perform a beam sweep to receive one or more RTS messages from one of the neighboring devices.

    Abstract: A method, an apparatus, and a computer program product for sustaining a link with a wireless network are provided. The apparatus communicates data with the wireless network via a first link with a first base station, acquires a resource to perform a beam training sequence with a second base station, wherein the acquired resource allows the beam training sequence with the second base station to be performed while the data is communicated via the first link, performs the beam training sequence and exchanging signaling information with the second base station using the resource to establish a second link to the second base station, evaluates a link strength of the second link based on the beam training sequence, and determines whether to switch the data communication from the first link to the second link based on the evaluation.

    Abstract: There is a need for a beam tracking technique that reduces the time needed to perform a beamforming procedure and that reduces beam overhead. The apparatus may determine a mapping between a first beam associated with a first type of channel and a second beam associated with a second type of channel. In an aspect, the first type of channel may be different than the second type of channel. The apparatus may receive the first beam associated with the first type of channel and the second beam associated with the second type of channel. In an aspect, the first beam and the second beam may be received from a second device.

    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may identify a number of beam directions that satisfy a transmission power condition. The UE may select a beam direction for a random access signal by choosing one of the beam directions that satisfies additional criteria, such as transmitting a random access message at the next opportunity. The transmission power may be selected based on a target receive power and a path loss for the selected beam. In some cases, if the sum of the path loss for a beam direction and the target receive power exceeds a maximum transmission power by more than a predetermined amount, the random access signal will not be transmitted using that beam. In some cases, if a response to the random access is not received, a different beam direction may be selected, the transmission power may be increased, or both.

    Abstract: One apparatus may be configured to detect a set of beams from a base station. The apparatus may be further configured to select a beam of the set of beams. The apparatus may be further configured to determine at least one resource based on the selected beam. The apparatus may be further configured to transmit, on the at least one determined resource, a beam adjustment request to the base station. The request may indicate an index associated with the selected beam. Another apparatus may be configured to transmit a first set of beams. The other apparatus may be further configured to receive a beam adjustment request on at least one resource. The other apparatus may be further configured to determine a beam index of a beam in the first set of beams based on the request and the at least one resource.
