摘要： A system and method of responding to a receiver outage event, which includes: determining if a receiver outage event has occurred; if a receiver outage event has occurred, discarding soft bits that were corrupted due to the outage event; and if a received first redundancy version (RV) of coded bits corrupted by the outage event was decoded incorrectly, sending a message to a transmitter in response to the outage event, and thereafter receiving a second RV of coded bits retransmitted by the transmitter in response to the message.

摘要： An improved method and system for achieving target function failure rates for time-critical functions. Communication systems often utilize distributed functions occurring in two or more nodes. Various embodiments of the invention enable such system to achieve target function failure rates by adjusting the maximum allowable duration for time-critical functions. Adjustments to either a function starting time or a maximum allowable function duration may be used to achieve target failure rates. Various embodiments measure a real-time function failure rate. Other embodiments simply lengthen or compress the maximum allowable function duration based on failure or success of the function. The function duration or the function duration statistics do not need to be known.

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.

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 method, system and non transitory, tangible computer readable storage medium provides for controlling the BLER (block error rate) in a digital communication system. The outer loop control of the system discounts responses sent by a receiver to data transmission from a transmitter that were sent during a receiver outage event. Either the NACKs or both the ACKs and NACKs sent by the receiver during receiver outage are discounted by the outer loop control which adapts subsequent transmissions by either directly adjusting transmission parameters or by adjusting the selection of transmission parameters. The adapting may be based on individual NACKs and ACKs or after establishing a BLER.
