Abstract: Methods, apparatuses, and computer program products are disclosed for facilitating decoding a communication received from a wireless terminal. Encoded bits are received from the wireless terminal via a shared uplink channel, and a plurality of acknowledgment tones are identified within the encoded bits. A correlation value is ascertained corresponding to a correlation between detected bits within the plurality of acknowledgment tones and valid bits corresponding to any of a plurality of valid acknowledgment codewords. A determination is then made as to whether the plurality of acknowledgment tones includes information corresponding to a discontinuous transmission by comparing the correlation value to a threshold value.

Abstract: Providing for noise estimation in wireless communication, and particularly for access request signals transmitted by a user equipment (UE), is described herein. By way of example, a wireless signal receiver can employ unused signal dimensions of a wireless network for noise estimation. In addition, the unused signal dimensions can be selected for time-frequency resources that are associated with a particular wireless channel, in order to obtain a noise estimate for that channel. By employing unused signal dimensions, a noise measurement is likely to include no other signal transmissions, and provide an accurate estimate of noise on that channel. According to various aspects of the subject disclosure, one or more Chu sequences employed for signal transmissions, root sequences thereof, or one or more cyclic shifts of a root sequence can be employed for the unused signal dimension.

Abstract: A communication system that facilitates transmissions in accordance with a single-carrier (SC) multiplexing scheme, a multi carrier (MC) multiplexing scheme or a combination thereof is disclosed. Based on various factors such as attributes associated with a UE (user equipment) or availability of resources, a base station can signal to the UE an appropriate multiplexing scheme to be adopted for particular transmissions. The UE can be scheduled for transmission in a semi-static mode wherein the UE employs the transmission scheme for a particular time interval or it may change the mode dynamically for different transmissions. For transmissions from the UE comprising a plurality of data streams with dissimilar attributes, the base station implements a MIMO (multiple input multiple output) system for the UE. This facilitates a UE to dynamically switch between or simultaneously adopt the various multiplexing schemes for communications and thereby fully utilize advantages associated with the different schemes.

Abstract: Aspects of the present disclosure provided techniques that may be applied in systems to allow for communication over a control channel utilizing a relatively narrowband (e.g., six physical resource blocks) based search space. An exemplary method, performed, for example, by a machine type communication (MTC) UE, generally includes identifying, within a subframe, a first search space to monitor for a control channel that occupies a first number of physical resource blocks (PRBs) that represents a narrowband within a system bandwidth comprising a plurality of narrowbands and monitoring at least the first search space for the control channel, wherein the control channel comprises broadcast control information.

Abstract: Certain aspects of the present disclosure generally relate to wireless communications, and more specifically to positioning reference signal (PRS) enhancements for enhanced machine type communication (eMTC). An example method generally includes determining a first bandwidth within a larger system bandwidth to transmit a first positioning reference signal (PRS) to a first type of user equipment (UE), determining a second bandwidth within the system bandwidth to transmit a second PRS to a second type of UE, and transmitting information associated with the first PRS and the second PRS.
