Abstract: A support clip can be configured to support objects relative to a cable support system having wire members. A support system engagement portion can have first, second, and third attachments, which can be removably attachable to the wire members of the cable support system. The first attachment can define a first partly cylindrical pocket with a first entrance, the second attachment can define a second partly cylindrical pocket with a second entrance, and the third attachment can define a hook that defines a third elongate pocket and a third entrance. The first and second attachments can be configured to receive respective wire members to attach the support clip to the cable support system in a first orientation and the second and third attachments can be configured to receive respective wire members to attach the support clip to the cable support system in a second orientation.

Abstract: A spring nut for attaching a threaded object to a structure with reentrant lips. The spring nut can include a base, a first arm and a second arm extending from the base in a first direction, and legs extending laterally from the base. The arms can include a support portion, a structure-engagement portion, and a thread-engagement portion that can be configured to secure the threaded object against axial loading in a second direction opposite the first direction. Crumple zones in the support portions can deform upon loading of the threaded object in the second direction to cause the structure-engagement portion to be urged into the reentrant lips. Each of the legs can extend at a first angle from the base, toward the structure-engagement portions, to be disposed to contact an exterior surface of the reentrant lips of the structure when the first and second arms are received in the channel.

Abstract: An attachment can secure an electrical box to a support structure without the use of fasteners. An attachment body can be configured to be secured to the support structure. One or more engagement arrangements can include first and second arms that are configured to engage first and second mounting openings of an electrical box without use of a separate fastener.

Abstract: Systems and methods for using a communication system in a spectrum are provided. For example, a random access or RACH procedure may be performed where the random access or RACH procedure may be configured to reduce secondary interference and/or to be used in a pixel-based environment. The random access or RACH procedure may include selecting a RACH preamble; sending a RACH preamble and/or format information; determining a transmission power of the RACH preamble and/or the format information; determining a random access radio network temporary identifier (RA-RNTI) and preamble ID associated with the RACH preamble; and/or selecting a physical RACH (PRACH).

Abstract: Methods and apparatus for spectrum coordination are described. A method of spectrum coordination includes a spectrum coordinator receiving a request for shared spectrum from a CRS that the spectrum coordinator supports. The request includes at least one minimum protection requirement. The spectrum coordinator determines protection criteria for the CRS based on the at least one minimum protection requirement received from the CRS. The spectrum coordinator sends the protection criteria for the CRS to a geo-location database for use in assigning shared spectrum to other CRSs that the spectrum coordinator does not support.

Abstract: A wireless network may implement a reduced bandwidth for control information transmitted and/or received on the wireless network. The reduced bandwidth may be used to avoid interference that may be detected from an in-band or adjacent channel. The reduced bandwidth may be used for transmission and/or reception of control information on a cellular or Wi-Fi channel. An eNB or an access point (AP) may signal to a wireless transmit/receive unit (WTRU) information associated with the reduced control channel, such as the power and/or the location of the channel in a frequency band. The control channel may be shifted to avoid a change in interference.

Abstract: A shared spectrum manager (SSM) may enable spectrum access for Tier 2 Users (T2Us) and Tier 3 Users (T3Us) while provisioning quality of access (QoA) in a dynamic shared spectrum environment while ensuring sufficient spectrum and interference protection for Tier 1 Users (T1Us). The SSM may enable new user spectrum authorizations by sending, to a regulator, a request for administrative information, and receiving, from the regulator, a policy and user authorization information for at least one user. The SSM may register a T2U with or without contacting the regulator. The SSM may perform quality based admission control by receiving periodic measurements from a master device of each T2U with an active frequency assignment indicating a Quality of Operation (QoO) experienced by the respective T2U, maintaining a map of an effective QoOs for a plurality of T2Us, and categorizing protection contours associated with each of the plurality of T2Us.

Abstract: A method and apparatus for coexistence among wireless transmit/receive units (WTRUs) operating in the same spectrum are disclosed. A wireless transmit/receive unit (WTRU) may include a processor that receives a configuration of a coexistence gap pattern defining a pattern of transmission periods and silent periods for the WTRU. The processor may control the WTRU to transmit information during the transmission periods and to not transmit information during the silent periods of the coexistence gap pattern.
