Described herein are methods to enable wireless cellular operation in unlicensed and lightly licensed, (collectively referred to as license exempt spectrum. Cognitive methods are used to enable use of unlicensed bands and/or secondary use of lightly licensed bands. Wireless devices may use licensed exempt spectrum as new bands in addition to the existing bands to transmit to a wireless transmit/receive unit (WTRU) in the downlink direction, or to a base station in the uplink direction. The wireless devices may access license exempt spectrum for bandwidth aggregation or relaying using a carrier aggregation framework. In particular, a primary component carrier operating in a licensed spectrum is used for control and connection establishment and a second component carrier operating in a licensed exempt spectrum is used for bandwidth extension.

A grant that includes a resource allocation for a subframe set may be communicated. The subframe set may include a subframe resource and another subframe resource following the subframe resource. Sensing, during a sensing time prior to utilization of the subframe resource, that the unlicensed spectrum is available may be performed. Transmitting, based on the sensing, data on the subframe resource and the another subframe resource without further sensing may also be performed.

A wireless communication network and method are described for enhancing cell-edge performance of a wireless transmit/receive unit (WTRU). The WTRU may establish a connection with a plurality of sites via respective downlinks (DLs). Each DL may include at least one DL component carrier (CC) that operates on a frequency that is the same or different than one or more of the other CCs. The sites may manipulate their transmit power for a particular CC operating frequency such that the distance from a particular one of the sites to its cell boundary may become larger by increasing its transmit power on the particular frequency, and the distance from at least one of the other sites to its respective cell boundary may become smaller by decreasing its transmit power on the particular frequency. Thus, a coverage overlap between different CC frequencies may be created while maintaining a frequency reuse pattern of one.

Disclosed herein is HARQ management, scheduling, and measurements, among other things, for cooperative communication. For example, methods herein may be used in situations wherein relaying or helping mechanisms may comprise the use of a relay node which is part of a fixed infrastructure or a relay node which may be a mobile wireless transmit/receive unit (WTRU). In said situations, a first transmission with first data is established between an evolved NodeB (eNB) and a WTRU. A second transmission with second data is established between a relay node (RN) and the WTRU. Said first and second data are combined for decoding. A single HARQ feedback for said first and second transmissions is sent from the WTRU to the eNB.

A heat exchange assembly for use in cooling an electrical component is described herein. The heat assembly includes a casing that includes an evaporator section, a condenser section, and a transport section extending between the evaporator section and the condenser section along a longitudinal axis. The casing is configured to bend along a bending axis oriented with respect to the transport section. The casing also includes at least one sidewall that includes at least one fluid chamber extending between the evaporator section and the condenser section to channel a working fluid between the evaporator section and the condenser section. A plurality of fluid channels are defined within the inner surface to channel liquid fluid from the condenser section to the evaporator section. At least one vapor channel is defined within the inner surface to channel gaseous fluid from the evaporator section to the condenser section.

In general, techniques are described for intelligently selecting test cases within testing environments. Specifically, a computing device may include a user interface with which a user interacts to specify a safety level. The device also includes a control unit that determines those functions of source code that changed. Based on these changed functions, the control unit determines those functions of the source code not changed but impacted by the changes within a set distance. The control unit then selects, for each of these determined functions, one or more test cases in accordance with one or more test selection algorithms by adaptively applying these algorithms in order of decreasing safety assurances and increasing precision. The control unit further aggregates these selected test cases and implement the test cases to ensure the safety level with respect to a percentage of functional errors occurring within a software program compiled from the source code.
