    摘要: To find a D2D channel, by example a shared channel for offload traffic from an allocated D2D channel, a cellular network access node sends a configuration message with parameters (e.g., sensing time, frequency band, sensing mechanism, cyclic shift) for a D2D device to sense spectrum. From results of this spectrum sensing is decided whether to utilize a frequency band, sensed according to the parameters, for D2D communications. In an embodiment the network selects a subframe configuration to set the sensing time, in which different subframe configurations have different-length guard periods which is the sensing time. In embodiments a first sensing is within a guard period and represents coarse sensing results and if those are not sufficient the network configures a longer sensing time (e.g., spanning multiple subframes) for finer sensing results. The network or alternatively the D2D device decides whether to use the sensed frequency band for offload traffic.

    摘要: Uplink and downlink traffic for a plurality of user equipments UEs in a cell is differentially weighted according to traffic type, and that weighted traffic total is used to select one uplink-downlink configuration for a radio frame from among A>1 possible uplink-downlink configurations. The weighting may use a priority factor or traffic class identifier that corresponds to the traffic type. In one embodiment the configuration selection is autonomous, and may be made to maximize throughput in the cell or to minimize a number of subframes that overlap with neighbor cells. In another embodiment there is a cooperation; one access node selects multiple candidate configurations which its neighbor cells score for their own acceptability and return the score tables to the original access node, who makes the final selection using the neighbors' score tables. Specific examples are in the context of the E-UTRAN/LTE system.

    摘要: Methods, apparatus and computer program products are provided for establishing a time-frequency reference signal pattern configuration in a carrier extension or a carrier segment, such as for cell-specific reference signals (CRS) and/or demodulation reference signals (DM RS). One method includes receiving information regarding a time-frequency reference signal pattern configuration in a carrier extension or carrier segment. The time-frequency reference signal pattern configuration defines a subframe to include a reference signal based upon a time density parameter and defines a resource element to be utilized within the subframe based upon a frequency density parameter. This method also includes receiving reference signals pursuant to the time-frequency reference signal pattern configuration such that reference signals have a coherence time Tcoh with at least one subframe including a reference signal in the CE or CS per Tcoh and a coherence bandwidth Bcoh with at least one resource element containing a reference signal per Bcoh.
