Abstract: A method, apparatus, and computer program product are described that receive an indication of power levels at the base station in a wireless communications system from each user equipment of user equipments served by the base station and determine whether at least one user equipment of those user equipments is capable to overlap at least one same time-frequency resource as at least one user equipment of a remainder of those user equipments. In response to the determination that at least one user equipment is capable to overlap with at least one user equipment of the remainder, then such overlap is scheduled. Based on the overlap being scheduled, packets from the one or more user equipments received are then decoded using an advanced receiver process.

Abstract: Various communication systems may benefit from identification of and communication of coverage shortfall. For example, certain communication systems that employ machine type communication devices may benefit from having such shortfall communicated from the devices to a base station. For example, a method can include determining an amount of coverage shortfall of a device. The method can also include transmitting an indication of the amount of coverage shortfall.

Abstract: A method includes allocating only a single PUCCH region in each subframe of multiple subframes to be used by UEs for uplink control information transmission. Information is signaled, where the information is defined to configure a UE that is equipped for machine type communication to be able to determine PUCCH regions to be used for uplink control information transmission for data received at the UE. The uplink control information is received, over the plurality of subframes, from the UE in the single PUCCH region per subframe. A UE that is configured for machine type communication receives the signaled information and determines, using the signaled information, a single PUCCH region to use for each subframe to transmit the uplink control information for received data and transmits, over the multiple subframes, the uplink control information from in the determined single PUCCH region per subframe. Apparatus, software, and computer program products are also disclosed.

Abstract: At a wireless node in a wireless network, multiple interference estimation resources are received in a time-frequency resource space. The multiple interference estimation resources are resource elements in an assigned physical shared channel of the time-frequency resource space that do not contain physical shared channel data for the wireless node. An interference covariance matrix is determined from received signals on the multiple interference estimation resources. Symbol estimates are determined for a desired signal based in part by using the interference covariance matrix. Methods, computer programs and products and apparatus are disclosed. The techniques may be used for uplink, downlink, or D2D communications.
