Abstract: Systems, methods and apparatus select a code book based on channel conditions and performance of a demodulator or demapper in a wireless receiver. The method may include determining that the receiver in a first wireless communication apparatus is configured for iteratively processing signals received from a channel, selecting a code book for use in communicating over the channel based on conditions affecting transmission of the signals through the channel and performance information associated with a demapper in the receiver, and identifying the selected code book in one or more control channels transmitted to a second wireless communication apparatus.

Abstract: Methods, systems, and devices for wireless communication are described. A method may include receiving a control transmission from a base station, identifying a control channel search space organized according to a nested structure, the control channel search space including a plurality of control channel candidates associated with one or more control channel elements (CCEs) and an aggregation level, and searching the received control transmission to identify a control channel for the UE using the plurality of control channel candidates. Another method may include determining whether to reorder resource element group (REG) indices for a received control channel transmission based, at least in part, on a transmission mode associated with the control channel transmission. Another method may include decoding a received control channel transmission, where the downlink control information (DCI) formats may be constrained to an integer multiple of a predetermined base number of bits N.

Abstract: Systems and methods for communicating mission-critical (MiCri) data in a network including a base station and user equipment (UE) are provided. The methods may include receiving a request message requesting MiCri data, and transmitting the MiCri data during a transmission time interval (TTI) of a first carrier component or during a transmission time interval (TTI) of a second carrier component. In various aspects, the TTI of the first carrier component may be staggered in time with respect to the TTI of the second carrier component. In another aspect, the UE may pre-report interference pattern information for a nominal TTI for use in communication of MiCri data.

Abstract: A method at a scheduling entity might include determining that interference is present from a neighboring scheduling entity, which implements a second subcarrier spacing that is different from a first subcarrier spacing of the scheduling entity. The scheduling entity might request the neighboring scheduling entity to negotiate a bandwidth group (BWG), where the BWG is a bandwidth occupied by downlink subcarriers within which a transmission parameter is maintained. The method might include negotiating a bandwidth of the bandwidth group and transmitting, if negotiating is successful, downlink data to a scheduled entity served by the scheduling entity according to the negotiated bandwidth. The transmission parameter might be a precoder, rank, modulation order, power inside each BWG, or numerology. The numerology might be scalable and might be a combination of subcarrier spacing and cyclic prefix (CP) overhead, The subcarrier spacing might be scaled while keeping constant the CP overhead as a percentage of a symbol duration.

Abstract: Systems and techniques are disclosed to enhance the efficiency of available bandwidth between UEs and base stations. A UE transmits a sounding reference signal (SRS) to the base station. The base station characterizes the uplink channel based on the SRS received and, using reciprocity, applies the channel characterization for the downlink channel. As part of applying the channel information, the base station forms the beam to the UE based on the uplink channel information obtained from the SRS. The UE may include an array of antennas, each UE transmitting a different SRS that the base station receives and uses to characterize the downlink. Multiple UEs (or a single UE with multiple antennas) transmit SRS at the same time and frequency allocation (non-orthogonal), but with each sending its own unique SRS. Further, multiple UEs (or a single UE with multiple antennas) may send their SRS at unique time/frequency allocations (orthogonal).

Abstract: Methods, systems, and devices for wireless communication are described A user equipment (UE) and a base station may support switching from one waveform to another on uplink channels. For example, a UE and a base station may utilize both frequency division multiplexing (SC-FDM) waveform and an orthogonal frequency division multiplexing (OFDM) waveforms based on channel conditions and other factors. In some examples, a UE may switch for some uplink channels, and use a single waveform for other channels. For example, switching waveforms for channels that utilize frequency domain code division multiplexing (CDM) channel may interrupt the orthogonality of multiplexed transmissions. A UE may transition from one waveform to another either autonomously or based on an explicit indication from a base station. If a UE switches autonomously, it may send an indication of the transition to the serving base station.

Abstract: Device detection in networks with mixed mobility devices is discussed. Devices in the network first determine a discovery mode from a plurality of discovery modes, wherein the determining is based on a mobility state of the wireless device. The device identifies a set of resources associated with the determined discovery mode, wherein each of the plurality of discovery modes is provisioned with separate resources. A discovery signal is transmitted using the identified set of resources according to the discovery mode. Thus, devices with higher mobility will generally send discovery signals more often than devices that are static or semi-static.

Abstract: An apparatus may receive, from a scheduling entity, sidelink grant information in a downlink control channel. After receiving the grant information in the downlink control channel, the apparatus may transmit a request-to-send (RTS) signal comprising an indication of a requested duration of time to reserve a sidelink channel for sidelink data. If the sidelink channel is available for the requested duration of time, the apparatus may receive a clear-to-send (CTS) signal configured to indicate an availability of the sidelink channel for the requested duration of time. Subsequently, the apparatus may communicate, with another apparatus different from the scheduling entity, the sidelink data using the sidelink channel during the requested duration of time. Afterwards, the apparatus may communicate acknowledgment information corresponding to the communication of the sidelink signal with the other apparatus. Various additional and alternative aspects are described herein.

Abstract: Methods, systems, and devices for wireless communication are described. In some examples, a wireless system may use a staggered uplink/downlink (UL/DL) format in which the symbol periods of the downlink are offset from the symbol periods of the uplink. Thus, if a user equipment (UE) receives a transmission in a first symbol period, it may decode the transmission and transmit a response in a staggered symbol period (e.g., in a UL control channel symbol period beginning one half of a symbol period after the first symbol period). A base station may then receive the response and, if it is a negative acknowledgement (NACK), retransmit during the third symbol period following the first symbol period. In another example, thin control channels may be used to reduce the round trip time between receiving a transmission and a retransmission.
