Abstract: Various communication systems may benefit from appropriately configured feedback. For example, certain embodiments may benefit from single cell point-to-multipoint feedback methods and mechanisms. A method can include determining by a user equipment, that a data transport block was not received. The method can also include feeding back, by the user equipment, a preamble indicating a measured downlink channel state information responsive to the determination that the data transport block was not received.

Abstract: Systems, methods, apparatuses, and computer program products for narrow band internet of things (NB-IoT) paging optimization are provided. One method includes, when extended discontinuous reception (eDRX) is not configured for a user equipment (UE), applying a maximum repetition number of each coverage enhancement (CE) mode for paging transmission and associating a different repetition number with each paging occasion (PO). When extended discontinuous reception (eDRX) is configured for the user equipment, the method includes associating each paging occasion (PO) with a different repetition number.

Abstract: Various communication systems may benefit from improved transmissions. For example, a network transmission may benefit from improved throughput and efficiency in non-schedule multiple access communications. A method includes selecting at a user equipment operating in a non-scheduled access scheme at least one of a first codeword or a second codeword based on an amount of data. The data in the non-scheduled access scheme can be spread according to a spreading sequence. The method also includes determining a transport block size for at least one of the first codeword or the second codeword. In addition, the method includes transmitting the data from the user equipment to a network node using at least one of the first codeword or the second codeword.

Abstract: A radio network sends downlink signaling to a user equipment (UE) that triggers an enhanced uplink beam selection protocol, based on quality of the UE's uplink signaling the network receives according to a basic uplink beam selection protocol. In response the UE transmits pre-defined signaling such as uplink beam references signals (U-BRS) with uplink beams according to the downlink signaling. The network measures and selects one or more of those uplink beams for the UE to use for sending uplink data, and notifies this selection to the UE. In various embodiments the basic uplink beam selection protocol is based on uplink-downlink reciprocity, the downlink triggering signaling is dynamic and further selects a subset of uplink beams, and multiple UEs can be triggered in common signaling where blind decoding by the UEs is enabled via a scrambling ID for this enhanced uplink beam selection protocol purpose.

Abstract: Configuration of various radio systems may have a number of possible benefits. For example, small cell configuration may be useful for interference mitigation. A method, in certain embodiments, can include determining a virtual subframe index for a cell. The method can also include communicating the virtual subframe index for the cell by communicating a time division duplex configuration and a relative subframe offset.
