    Abstract: In multi-beam operation, path losses or other aspects of electromagnetic signal propagation, may make it necessary to restrict certain beam directions used between two devices. A base station determines a restricted-beam set including at least one beam direction that is restricted for at least one of a signal transmission or a signal reception. The base station also restricts at least one of a transmission or a reception of a signal based on the restricted-beam set. Additionally, the base station determines an updated restricted-beam set including at least one beam direction that is restricted for at least one of transmission or reception of an electromagnetic signal. The base station also updates the restricted-beam set by adding or removing at least one beam direction to the restricted set corresponding to at least one of signal transmission or signal reception.

    Abstract: Certain aspects of the present disclosure provide techniques for random access channel (RACH) communication. For example, certain aspects provide a method for wireless communication by a user-equipment (UE). The method generally includes transmitting a first message comprising a RACH preamble, receiving a second message comprising random access response (RAR) in response to the RACH preamble, transmitting a third message in response to the RAR, receiving a fourth message (MSG4) comprising a contention resolution message in response to the third message. In certain aspects, the fourth message may include a timing advance (TA) parameter which may be used to communicate one or more messages.

    Abstract: Access terminals are provisioned to conduct intra-frequency, inter-frequency, and inter-RAT measurements and report physical layer identifiers of detected cells. The provisioning may involve cycling through all or a portion of a defined superset of physical layer identifier one subset at a time. In addition, the physical layer identifiers may be prioritized to improve the search procedure. Measurement report messages (including physical layer identifiers of the detected cells) are received at an access point as a result of the provisioning. A neighbor cell list for the femtocell is maintained based on the received measurement report messages and, optionally, other information. This other information may related to, for example, one or more of: physical layer identifier information received from access terminals that register with the access point, physical layer identifier information received via network listen operations, information regarding co-located cells, or physical layer identifier information received from a network entity.

    Abstract: The present disclosure presents a method and apparatus for joint power and resource management in a wireless network. For example, the disclosure presents a method for receiving reference signal received power (RSRP) measurements of one or more neighboring base stations of a base station. In addition, such an example method, may include calibrating a transmit power of the base station based at least on the received measurements, and adjusting transmit resources of the base station in response to the calibration. As such, joint power and resource management in a wireless network may be achieved.
