Hidden node detection in LTE licensed assisted access
The application relates to improved hidden node detection for Long Term Evolution LTE Licensed-Assisted Access LAA. Channel State Information CSI measurements can be seen as one existing solution that could be used for obtaining information about the existence of a hidden node. However, relying on CSI reporting alone is rather unreliable. One of the reasons for this is that the CSI measurements and reporting do not take into account the regulatory requirements such as LBT. A further possible way to detect hidden nodes is to perform LBT (clear channel assessment CCA) at the transmitter (e.g. eNB) and receiver (e.g. UE) at the same time. However, there is still the need for an improved solution for how to detect hidden nodes preventing LTE LAA uplink operation and complicating coexistence. These problems are solved by ensuring that interference from non-hidden nodes (such as WLAN node 1 in FIG. 1) is not measured. Therefore the serving eNB detects a free channel during LBT procedure, i.e. that non-hidden nodes are not transmitting, and informs the UE which performs the hidden node detection measurements, by downlink scheduling, whether the serving eNB is active in the current subframe. The UE then performs the measurements only in subframes of the channel occupied by the serving eNB. Thereby, the UE only captures interference coming from hidden nodes. |

Systems and methods for player input motion compensation by anticipating motion vectors and/or caching repetitive motion vectors
Systems and methods for reducing latency through motion estimation and compensation techniques are disclosed. The systems and methods include a client device that uses transmitted lookup tables from a remote server to match user input to motion vectors, and tag and sum those motion vectors. When a remote server transmits encoded video frames to the client, the client decodes those video frames and applies the summed motion vectors to the decoded frames to estimate motion in those frames. In certain embodiments, the systems and methods generate motion vectors at a server based on predetermined criteria and transmit the generated motion vectors and one or more invalidators to a client, which caches those motion vectors and invalidators. The server instructs the client to receive input from a user, and use that input to match to cached motion vectors or invalidators. Based on that comparison, the client then applies the matched motion vectors or invalidators to effect motion compensation in a graphic interface. In other embodiments, the systems and methods cache repetitive motion vectors at a server, which transmits a previously generated motion vector library to a client. The client stores the motion vector library, and monitors for user input data.

Techniques for video exchange are disclosed in which a video source sends redundant copies of video coded at a given presentation time.
