摘要： A new approach to generating a probing signal by a cell in a heterogeneous network (HetNet) deployment is proposed. A small cell in the HetNet may be switched off by a base station when the small cell is not needed. The small cell is configured to alternate between an off-state and on-state. The small cell maintains the on-state for a predetermined probing period and maintains the off-state for a predetermined off period. The small cell may switch between the on-state and the off-state periodically. The small cell may be activated during a predetermined off period to transmit data to a user device.

摘要： A new approach to anti-blocking cellularcommunication for HetNet deployment is proposed. First, a block detector sends a block indicator from an LPN to a scheduler in a macro base station. The scheduler then collects the block indicator statistics of each LPN on a sub-frame basis and updates the statistics in each sub-frame. If the statistics of received block indicators for one sub-frame during an observation period of a specific LPN exceeds a first predefined threshold, then the scheduler will not schedule any more uplink transmission to the LPN during the sub-frame for those UEs which are connected to the LPN. When the statistics of received block indicators becomes less than a second predefined threshold, which is less than the first threshold, the scheduler removes the limitation on uplink transmission to the LPN and allocates the sub-frame of the LPN as usual.
摘要翻译：提出了一种用于HetNet部署的防止蜂窝通信的新方法。首先，块检测器将块指示符从LPN发送到宏基站中的调度器。然后，调度器在子帧的基础上收集每个LPN的块指示符统计，并更新每个子帧中的统计。如果在特定LPN的观察期间的一个子帧的接收块指示符的统计信息超过第一预定义阈值，那么在连接的那些UE的子帧期间，调度器将不会调度对LPN的更多上行链路传输到LPN。当接收到的块指示符的统计信息变得小于小于第一阈值的第二预定义阈值时，调度器消除对LPN的上行链路传输的限制，并像往常一样分配LPN的子帧。

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.

摘要： The proposed approach comtemplates systems and methods configured to utilize a modified reference signal to facilitate efficient discovery of as many cells as possible within one channel state information reference signal (CSI-RS) sub-frame while maintaining certain detection and measurement performance. The proposed approach is configured to unambiguously discover at least the number of anticipated small cells within one cluster and to further identify all small cells within the coverage area of a base station/macro cell. In some embodiments, frequency multiplexing is utilized to allow different cells to transmit their discovery signals on different physical resource blocks (PRBs) rather than one cell using every PRB over the entire system bandwidth.

摘要： The proposed approach contemplates systems and methods configured to transmit signals irregularly (sparsely) over a mobile communication network (carrier) in which reception gaps apply while increasing the likelihood that receivers will receive a signal at least once during a certain time period, called irregular signal period. First, a set of transmission offsets is selected, the transmission offsets defining a relative transmission time in a burst, such that if a burst would be transmitted using the selected transmission offsets, a receiver with any valid reception gap configuration would receive at least one signal in its whole duration. Then, during an irregular signal period, signals are transmitted in a sequence of one or more consecutive bursts using each of the transmission offsets in the selected set at least once, wherein the sequence of bursts may be preceded and/or followed by a period of no signal transmission. Finally, a receiver receives at least one of the irregular signals in its whole duration during one of the reception gaps of the receiver.
