Abstract: A network access node identifies a component carrier within an unlicensed radio spectrum, determines whether or not to configure the component carrier for use as a secondary component carrier, and based on the determining configures the component carrier for use as a secondary component carrier companion to a primary component carrier within a licensed radio spectrum, In various non-limiting embodiments the network node senses the component carrier within the unlicensed radio spectrum, and as more data is needed to make the determination employs a mobile device to also sense and further to measure the component carrier within the unlicensed radio spectrum. Specific procedures are detailed for both the network node and the mobile device.

Abstract: A method includes determining one of a multiplicity of subframes in a resource space in which a shortened subframe is to be communicated. Each of the subframes has a predetermined number of symbol positions. The resource space includes the multiplicity of subframes. The method includes communicating the shortened subframe in the determined subframe. The shortened subframe has a multiplicity of active symbols at first symbol positions in the determined subframe and has a multiplicity of blanked symbols at second symbol positions in the determined subframe. In an embodiment, each of the subframes is a first subframe carried on subcarrier. The resource space corresponds to a special subframe in a frame including the special subframe and a multiplicity of second subframes. The special subframe and the plurality of second subframes are located in different timeslots. Apparatus, computer programs, and program products are also disclosed.

Abstract: An apparatus, method and system to reduce interference between frequency-division duplex and time-division duplex signals in a communication system. In one embodiment, an apparatus includes a processor (520) and memory (550) including computer program code. The memory (550) and the computer program code are configured to, with the processor (520), cause the apparatus to allocate a time-division duplex carrier for a frequency-division duplex downlink signal for communication with a communication element, and employ the time-division duplex carrier with a truncated time duration for the frequency-division duplex down-link signal.

Abstract: Methods, apparatus and computer program products are provided for rebalancing the sizes of downlink (DL) association sets for component carriers having different time division duplex subframe configurations. A method is provided that includes determining DL subframes that are included in a DL association set for each of a plurality of component carriers. In an instance in which the number of acknowledgement (ACK)/negative acknowledgement (NACK) bits corresponding to the DL subframes included in the DL association sets for respective component carriers differ by at least a predetermined amount, the method modifies the number of ACK/NACK bits corresponding to the DL subframes that are included in the DL association sets for each of the respective component carriers. The method may also cause transmission of the ACK/NACK bits in accordance with the DL association sets, as modified, via the respective component carriers. Corresponding apparatus and computer program products are also provided.

Abstract: A wireless terminal operating in TDD mode transmits a plurality of sounding reference signals using an assigned maximum sounding reference signal (SRS) bandwidth (BW) size. At least one of the sounding reference signals is transmitted in a corresponding uplink pilot time slot (UpPTS) region of a special sub-frame of a radio frame wherein, in the frequency dimension, an uplink BW center is misaligned with a BW center of the SRS in the UpPTS region, a maximum SRS BW size in the UpPTS region is an even number of resource blocks with prime factors from a set of {2, 3, 5}, and the maximum SRS BW having a size in number of resource blocks less than or equal to (NRBUL?6·NRA) where NRA is a number of Random Access Channel (RACH) opportunities in the UpPTS region.

Abstract: A container data center is disclosed in the present invention, relating to the field of data centers. The container data center includes: a container box, in which the inside of the box is divided into an equipment compartment, a power supply and distribution compartment and a water chilling set compartment; doors set in the box; a power supply equipment installed in the power supply and distribution compartment; an electronic equipment and a water chilling terminal installed in the equipment compartment; a water chilling set installed in the water chilling set compartment, in which the water chilling set is in communication with the water chilling terminal to provide cold water for the water chilling terminal.

Abstract: A container-type data center is provided in embodiments of the present invention, including a container, cabinets, computing devices, and cooling devices. The cabinets are arranged in rows inside the container. The computing devices are set inside the cabinets. Air enters from one side of each of the cabinets and exhausts from another side to form left-to-right air vents. The left-to-right air vents are connected in series. In the series air vents of the cabinets, multiple cooling devices are set. In the container, a maintenance passage is formed for maintaining the cabinets. Maintenance planes of the cabinets face the maintenance passage. In the embodiments of the present invention, the air enters from one side of each of the cabinets and exhausts from the other side to form the left-to-right air vents, and the maintenance planes of the cabinets face the maintenance passage. In this way, the maintenance convenience is greatly improved.

Abstract: A container-type data center, including a container, at least three rows of cabinets, and data processing devices, is provided. The data processing devices are disposed in the cabinets. The at least three rows of the cabinets are disposed in parallel and perpendicular to a long edge of the container. Two neighboring rows of the cabinets of the at least three rows of the cabinets are back-against-back disposed or disposed at intervals, in which when the two neighboring rows of the cabinets are disposed at intervals, a maintenance channel is formed from the space between the two neighboring rows of the cabinets. As the at least three rows of the cabinets are disposed in parallel and perpendicular to the long edge of the container, the cabinets of each row are not limited to a width of the container in a width direction, and a cabinet with a large size can be integrated, thereby improving an integration level of the container.
