Abstract: Systems and methods are provided for transmitting and receiving pre-emption indications. The pre-emption indication is transmitted every K symbols or slots, on a group-common physical downlink control channel. The pre-emption indication is in respect of a group of K symbols or slots preceding a symbol or slot containing the group-common pre-emption indication. The group-common pre-emption indication indicates, for the group of K symbols or slots, which resources are pre-empted. The base station schedules resources for first downlink traffic, and transmits the scheduled first downlink traffic subject to pre-emption, and transmits second downlink traffic by pre-empting resources for the first downlink traffic. On the UE side, the UE receives the pre-emption indication. The UE receives its scheduled traffic taking into account the pre-emption indication.

Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for a segmented ECF that includes multiple filter components to replicate an echo pulse response. The different filter components are used to replicate different portions of the echo pulse response. Each filter components can include filter coefficients of different sizes based on the portions of the echo pulse response that is replicated by the filter component. For example, a filter component that replicates a portion of the echo pulse response that includes a large reflection can include large filter coefficients suitable to replicate the larger reflection. In contrast, a filter component that replicates a portion of the echo pulse response that includes smaller reflections can include smaller filter coefficients that are suitable to replicate the smaller reflection. The output of each of the filter components is combined to replicate the full echo pulse response.

Abstract: The technique herein optimizes delivery performance from a content delivery network (CDN) edge node, preferably by using knowledge of radio link allocation behavior. According to the technique herein, an IP address of a cellular end user (or equivalent) is recognized by the CDN edge. Then, preferably by tracking idle times both in consecutive downloading bursts in the end user session and in an on/off style radio link allocation pattern, the CDN edge adjusts transport layer network protocol parameters. The approach (which leverages the cross-layer intelligence obtainable from existing CDN infrastructure) thus enables the transport layer protocol implemented at the edge to optimize the delivery performance over the cellular mobile network.
