摘要： A method of small cell discovery in a wireless network deployment using a Channel State Information Reference System (CSI-RS) is proposed. First, a wireless communication system allocates pairs of resource elements in each resource block of a subframe to a CSI-RS configuration. A first of two orthogonal cover codes is applied to the first CSI-RS. The CSI-RS is transmitted by a small cell to a user equipment (UE). The UE utilizes the CSI-RS to perform small cell discovery and measurement of the small cell.

摘要： Provided is a synchronization cell used in a wireless communication system. Also provided is an SCI, synchronization cell indicator. A mobile network includes a processor that identifies one or more suitable synchronization cells for a user equipment (UE) and sends the SCI to the UE so that the UE can at least partially synchronize with a synchronization cell. The SCI advantageously includes a cell-id and other synchronization parameters and characteristics in various embodiments. The SCI may include a cell-directed UE action for the UE to carry out with a target cell. The UE carries out cell-directed UE actions with the target cell either after having obtained synchronization with the synchronization cell or to continue the synchronization process.

摘要： A new approach to deployment of a hybrid node in a cellular communication network is proposed, wherein the hybrid node includes a plurality of antennas that simultaneously serve a plurality of cells in the cellular communication network by transmitting or receiving signals to or from the cells at the same time. The cellular communication network further includes a partner cell among the plurality of cells served by the hybrid node, wherein the partner cell is a soft cell that maintains communication channels with antennas of more than one node at the same time. The cellular communication network further includes a hybrid cell among the plurality of cells also served by the hybrid node, wherein the hybrid cell is a hard cell that maintains communication channels with antennas of only one node at any one time. The partner cell and the hybrid cell have different cell-ids and they each connects to and serves a plurality of user equipment (UE) for uplink communication to and downlink communication from the hybrid node.

摘要： A serving cell configures a search window within which a UE searches to find a discovery burst. The discovery burst may include PSS, SSS, DS, CSI-RS or other signals. The UE detects synchronization signals and determines if the synchronization signals are part of the discovery burst by detecting signal properties to distinguish them from legacy or other synchronization signals. One property is the time difference between a PSS and an SSS in a discovery burst. Other properties are the frequency difference between a PSS and an SSS, and the sequence of the synchronization signals. If the UE determines that the synchronization signals are part of the discovery burst, the UE performs RRM measurements on other signals in the discovery burst, and reports the measurements results to a serving cell. The serving cell decides if a UE should be handed over to the measured cell based on the measurement reports.

摘要： A method and system for wireless communication system provide for transmitting a scheduling grant to a User Equipment (UE) and configuring the UE with a configurable time offset. The method and system also provide for transmitting a scheduling grant to a node and configuring the node with a configurable time offset. The UE transmits or receives a communication scheduled by said scheduling grant, and this transmitting or receiving a communication is delayed from said transmitting a scheduling grant by the configurable time offset. The configurable time offset may be an integer of multiple orthogonal frequency division multiplexing (OFDM) symbols in some embodiments and postpones or adjusts the UE transmitting or receiving a communication, with respect to a regular start time based on the scheduling grant. The method and system find application in cross-carrier and cross-node systems.

摘要： A plurality of signal transmissions, transmitted using a plurality of transmit powers, are received at a receiver over a communication channel. Each transmit power shares a common transmit power term unknown to the receiver and a signal-specific power offset known to the receiver. The received power is measured at the receiver. A corresponding known power offset is subtracted from the measured received signal power, resulting in a corresponding estimate of the common unknown power term. This results in a plurality of estimates of the common transmit power term. A refined common transmit power term is estimated from the plurality of estimates of the common transmit power term. A plurality of refined measured received signal powers are estimated by adding the plurality of signal-specific power offsets to the refined common power term. Based on the refined common transmit power term, a functionality of the wireless communication system is adapted.
