    Abstract: A method and apparatus may include determining that downlink communication is to be scheduled for transmission to user equipment. The method may also include scheduling the downlink communication. The method may also include scheduling uplink communication. The uplink communication is transmitted by user equipment to the network node. The uplink communication and the downlink communication are transmitted such that (1) uplink frequency resources are the same as downlink frequency resources, (2) uplink frequency resources are contained within downlink frequency resources, or (3) uplink frequency resources overlap with downlink frequency resources. The method may also include signaling user equipment to ignore a carrier sensing mechanism. User equipment transmits the uplink communication at a time specified by the network node.

    Abstract: A method includes scheduling, by a base station configured to service a cell within a cellular communication network, multiple grants to an apparatus in a coverage area of the cell. Each of the scheduled multiple grants includes time-frequency resources in at least one shared spectrum that is to be used by the apparatus to attempt to communicate. Each of the scheduled multiple grants differs from others of the scheduled multiple grants in one or both of time or frequency. The method includes sending indications of the scheduled multiple grants. Another method includes receiving, at the apparatus in the cell, indications of the multiple grants and attempting by the apparatus to communicate using one or more of the multiple grants. Apparatus, computer programs, and program products are also disclosed.

    Abstract: A method includes receiving a two-bit information stream comprising first and second bits and performing precoding using the two-bit information stream to determine multiple output signals. The precoding is performed to create a finite multiple of states for the output signals. The output signals comprise a first output signal based on a version of the first input bit and on a version of a second input bit, a second output signal based on a delayed version of the first input bit and the version of the second input bit, and a third output signal based on the version of first input bit and a delayed version of the second input bit. The method includes performing pulse shaping of each of the output signals to create pulse-shaped signals, combining the pulse-shaped signals to create a transmission waveform, and outputting the transmission waveform. Apparatus, computer programs, and computer program products are disclosed.

    Abstract: Improved mechanisms for wireless cellular access using coverage extension techniques are described. A UE needing to use coverage extension to request access to a prospective serving cell detects cells (other than the prospective serving cell) on its frequency, and then investigates each such cell (for example, by attempting to read its system information block and, if the system information block can be read, determining if the cell supports access using coverage extension. If detected cells do not support coverage extension, the UE does not use coverage extension techniques to request access, but if all detected cells support coverage extension, the UE requests access using coverage extension techniques.

    Abstract: Methods, apparatuses, and computer program products for providing uniform user equipment initialization procedure for both in-coverage and out-of-coverage device-to device communications are disclosed herein, incorporating a novel tri-timer design: an initial timer, a search timer, and an active timer. In a method a determination is made regarding a user equipment as being a clusterhead candidate which can act as a clusterhead of a cluster. The user equipment searches for a suitable cell or cluster to join. If a suitable cell or a cluster is not found, the user equipment is selected to be a clusterhead which will act as the clusterhead of its own cluster. After selecting the user equipment to be a clusterhead and establishing its cluster, the user equipment transmits a discovery signal which alerting other user equipment to the clusterhead, to which the other user equipment can join. The user equipment as clusterhead then maintains the cluster.

    Abstract: Various communication systems may benefit from efficient communication of system information. For example, certain wireless communication systems may benefit from system information block enhancement for low complexity user equipment and/or user equipment in coverage enhancement mode. A method can include decoding a transport block size (TBS) index in a compact downlink control information. The method can also include monitoring for SIB based on the decoded TBS index. The method may optionally include monitoring for the SIB based on a predefined transmission pattern of physical downlink control channel for machine type communication. The method may also optionally include decoding of M-SI messages from a subframe according to a pattern indicated by an information element in M-SIB1.
