The system may include: a signaling unit; a contact center bell application, a particular reflector associated with a virtual hangout, and a contact center manager application. The system may further include a room manager application. The method may include: transmitting a call request to the integration unit, wherein call information corresponding to the call request is sent to the contact center manager; and connecting to the communications session, which corresponds to a virtual hangout identification received by the integration unit from the contact center manager based on the call information.

Abstract: In a system using spatial precoding, in the event that reliable channel state information is unavailable, a transmitting node uses an extended transmission mode, in which the precoders applied to data within each of several groups of time-frequency resources vary according to frequency. The extended transmission mode creates a frequency-selective variation in precoders, which may appear to be random, while using DMRS-based transmission. This variation is achieved by applying different precoders to the resource elements carrying data, using a pattern of precoder variation that is known to the receiving device. The precoding applied to DMRS within a given group of time-frequency resources is held constant—thus, the varying precoders within a given group of time-frequency resources are only applied to data elements, not to the DMRS resource elements.

Abstract: Provided is a method for transmitting signals in a relay station. In detail, the method for transmitting signals in a relay station of a wireless communication system using a plurality of subframes including a plurality of OFDM symbols or SC-FDMA symbols comprises the steps of: receiving bitmap information on a backhaul downlink subframe from the relay station; obtaining control information on a subframe that is not used for a backhaul downlink; and repeatedly transmitting channel state information to the relay station on the basis of a virtual index indicating only a backhaul uplink subframe, wherein the backhaul uplink subframe is determined according to the control information and the bitmap information.

Abstract: Provided is a terminal device that is capable of improving the characteristics of a response signal having poor transmission characteristics when ARQ is utilized in communication using an uplink unit band and a plurality of downlink unit bands associated with the uplink unit band. At the time of channel selection, a control unit (208) selects a resource used in sending a response signal from among specific PUCCH resources notified in advance from a base station (100) and PUCCH resources mapped to a CCE, and controls the transmission of the response signal. A response signal generating unit (212) supports implicit signaling with respect to any given response signal, and at the same time as supporting LTE fallback from 2CC, uses a mapping method that, between bits, smooths the number of PUCCH resources that can determine ACK/NACK simply by determining the PUCCH resource regarding which the response signal had notified.

A received signal power, such as a Reference Signal Received Power (RSRP) or a Reference Signal Received Quality (RSRQ), or a combination thereof, is also measured from the at least one neighbor cell. Identifying information and the received signal power of the at least one neighbor cell is then communicated to a network entity of the wireless network.

Based on the information received from the network entity, the base station enables a reconfiguration of the allocation of uplink and downlink subframes used in the cell.
