Abstract: Technology is discussed for supporting the incorporation of a Primary Synchronization Signal (PSS) and/or a Secondary Synchronization Signal (SSS) within in a New Carrier Type (NCT) for a Component Carrier (CC). Guidelines for incorporating the PSS and/or the SSS in the NCT are discovered, together with potential collisions with other signals that can be avoided for various scenarios. In some examples, various guidelines and potential collisions discovered herein, for various scenarios, inform approaches to incorporating the PSS and/or the SSS based on the positioning of the PSS and/or the SSS. In other examples, other signals, such as DeModulation Reference Symbols (DMRS) are reconfigured to allow incorporation of the PSS and the SSS.

Abstract: Embodiments are provided for uplink measurement based mechanism and control using user equipment (UE) centric sounding signals. The mechanism provides an alternative to DL-measurement dominated system control. Based on UL-measurements at TPs, the network obtains knowledge of users' channel and timing information, traffic, and interference, and is thus able to perform better control, including TP and UE clustering and optimization, and power control and link adaptation. In an embodiment method, a TP receives one-to-one mapping information indicating a plurality of UE IDs and a plurality of sounding channels assigned to the corresponding UE IDs. When the TP detects a sounding reference signal (SRS) from a UE, the TP is able to identify the UE using the detected SRS and the one-to-one mapping information. The TP then obtains measurement information for the identified UE, enabling better control and communications for uplink and downlink transmissions between multiple TPs and the UE.

Abstract: Provided is control information related to polarizations of antennas for MISO communication. The control signal generator generates polarization information indicating whether antennas used for transmission by MISO have only a first polarization or have a second polarization as well as the first polarization. With this structure, the present invention allows for the use of combinations of SISO, MISO and MIMO, taking the polarization of antennas. Furthermore, the present invention enables the receiver to reduce the power consumption.

Abstract: [Problem] To provide a transmission device that has an enhanced redundant structure in which RF signals having a plurality of frequencies are transmitted to continue transmission even in the event of failure and allows simultaneously both improvement in power efficiency and transmission power and high-speed communication.[Solution] A signal generator 1102 generates RF signals 1201 to 1204. Each of the RF signals 1201 and 1202 is simultaneously input to a broadband/multiband power amplifier 1103, and each of the RF signals 1203 and 1204 are simultaneously input to a broadband/multiband power amplifier 1104. Specifically, the RF signals allocated in two different bands 1211 and 1212 are simultaneously input to each of the power amplifiers. The RF signals 1201 to 1204 are amplified by the broadband/multiband power amplifiers 1103 and 1104 and then transmitted via terminals 1105 and 1106.

Abstract: Uplink CoMP point selection is achieved, considering power consumption of a MTC device and uplink overhead.Two resource blocks of a first resource block containing a reference signal and a second resource block for transmitting user data are combined to achieve uplink CoMP. The time interval between these two resource blocks is a time of approximately several milliseconds to several tens milliseconds necessary that each eNodeB acquires reception quality to be collected to a Serving eNodeB via the X2 interface and analyze its content.

Abstract: Systems and methods are disclosed for communicating enhanced user equipment (UE) assistance information between nodes in wireless communication systems. The UE achieves power savings and latency requirements more effectively by communicating its preferences, constraints and/or requirements to an evolved Node B (eNodeB) in the form of UE assistance information. The UE assistance information may include, for example, an indication of a preferred set of discontinuous reception (DRX) settings, current data traffic conditions, expected data traffic conditions, power or performance preferences, and/or an indication of the UE's mobility between cells.

Abstract: Described embodiments provide a digital unit for controlling a plurality of radio units to transmit a signal to user equipment. The digital unit may determine whether user equipment is located at an overlapping service area of a first radio unit and a second radio unit and control the first radio unit to transmit a signal to the user equipment using the first antenna and control the second radio unit to transmit the same signal to the user equipment using the second antenna when the user equipment is located in the overlapping service area. A transmission pattern of the first antenna of the first radio unit may be different from a transmission pattern of the second antenna of the second radio unit.
