Abstract: Wireless communication devices are adapted to facilitate transmission and reception of non-orthogonal communications. In one example, wireless communication devices can encode an amount of data in accordance with information that at least some of the data will be transmitted as part of a non-orthogonal transmission. The wireless communication device may further transmit the encoded data, and the encoded data can be non-orthogonally combined as part of a non-orthogonal transmission. In another example, wireless communication devices can receive a wireless transmission including a plurality of data streams non-orthogonally combined together. The wireless communication device may decode at least one of the data streams. Other aspects, embodiments, and features are also included.

Abstract: An apparatus may utilize an air interface to transmit and/or receive a subframe having a data portion and a control channel that is at least partly embedded within the data portion. The control channel may include one or more pilot tones. The control channel may include an override indicator. The override indicator may indicate that data previously scheduled for transmission in the subframe is overridden by other data having a higher priority. The override indicator may indicate a puncturing of resource elements in the data portion of the subframe to include other data having a priority higher than data previously scheduled for transmission in the subframe. The control channel may include a modulation indicator when the subframe is included in a multi-user multiple-input multiple-output (MU-MIMO) transmission. The modulation indicator may indicate information corresponding to a modulation of another apparatus that is included in the MU-MIMO transmission.

Abstract: Methods, systems, and devices for wireless communication are described. A method may include identifying a reference number of tones for an overhead channel of a transport block and segmenting the transport block into a code block based at least in part on the reference number of tones for the overhead channel. In some examples, a code block indicator or the reference number of tones may be transmitted on a control channel. Another method may include receiving a code block size indicator associated with a code block of a transport block, decoding the code block based at least in part on the code block size indicator and assembling the transport block based at least in part on the decoded code block. In some examples, the code block size indicator may be received using a control channel.

Abstract: The disclosure relates in some aspects to an energy-aware architecture that supports a low power scheduling mode. For example, a media access control (MAC) architecture for a base station (e.g., an enhanced Node B) and associated access terminals (e.g., UEs) can take the power needs of the access terminals into account when scheduling the access terminals. In some aspects, an access terminal may support a particular frame structure for a low power mode. Accordingly, scheduling of the access terminal may include use of the particular frame structure during low power mode.

Abstract: Aspects of the present disclosure provide a self-contained subframe structure for time division duplex (TDD) carriers. Information transmitted on a TDD carrier may be grouped into subframes, and each subframe can provide communications in both directions (e.g., uplink and downlink) to enable such communications without needing further information in another subframe. In one aspect of the disclosure, a single subframe may include scheduling information, data transmission corresponding to the scheduling information, and acknowledgment packets corresponding to the data transmission. Furthermore, the subframe may additionally include a header and/or a trailer to provide certain bi-directional communications functions.

Abstract: Systems, methods, apparatuses, and computer-program products for performing dynamic bandwidth switching between control signals and data signals of differing bandwidths are disclosed. A wireless communication apparatus comprises a memory and a processor coupled to the memory. The processor is configured to transmit a control signal to a user equipment (UE) using a first bandwidth. The processor is further configured to transmit a data signal to the UE using a second bandwidth wider than the first bandwidth. The control signal and the data signal are transmitted over a single carrier frequency. The control signal comprises an indication of a characteristic of the data signal. The data signal is transmitted after the control signal such that the data signal and control signal are separated by a time interval. The time interval is based on at least a switching latency of the UE.

Abstract: Methods, systems, and devices are described for wireless communication. In one method, a method of wireless communication at a user equipment (UE) includes receiving a synchronization signal. The synchronization signal may be common to a plurality of cells within a network. The method further includes acquiring a timing of the network based on the synchronization signal, and transmitting a pilot signal in response to acquiring the timing of the network. The pilot signal may identify the UE and be concurrently receivable by the plurality of cells within the network. Other aspects, features, and embodiments are also claimed and described.

Abstract: Control information may be identified and provided to a user equipment (UE) that is formatted into a codeword that is transmitted in a first symbol of a downlink transmission to the UE. The control information may include an allocation of downlink or uplink resources for the UE and data processing parameters. The control information may be partitioned into first control information transmitted in a first codeword and second control information that may be formatted into a second codeword. The second control information may be determined based at least in part on the data acknowledgment from the UE. Such partitioned control information may allow a base station to perform some processing related to transmissions for a transmission time interval (TTI) prior to the start of the TTI, and allow the base station to perform some processing for the TTI after the start of the TTI.

Abstract: Systems, devices, and methods associated with interference aware sounding reference signals are provided. A method for wireless communication includes receiving, at a wireless communication device in communication with a first base station, an interfering signal from a second base station (or other base stations); determining, at the wireless communication device, a spatial direction of the interfering signal; and transmitting, with the wireless communication device, a signal to the first base station based on the spatial direction of the interfering signal. Another method of wireless communication includes receiving, at a first base station, a signal from a wireless communication device, the signal based on a spatial direction of an interfering signal received by the wireless communication device from a second base station (or other base stations); transmitting, with the first base station, a downlink communication to the wireless communication device, the downlink communication beamformed in the spatial direction based on the signal received from the wireless communication device.
