Abstract: Methods, systems, and devices for wireless communication are described. The methods, systems, and devices provide for identifying tone spacing for transmission or reception of signals. The identified tone spacing may vary depending on the transmission or reception spectrum band or signal type. Using the identified tone spacing, a number of repetitions or a number of symbols for transmission or receiver algorithm of a signal may be determined.

Abstract: Methods, systems, and devices for wireless communication are described. Methods, systems, and devices provide for different tone spacing schemes for different channels. Methods, systems, and devices also provide for different tone spacing schemes for different stages of communication between a UE and a base station. The base station may indicate, to the UE, the tone spacing scheme in a control channel, a synchronization signal, or a reference signal and the tone spacing scheme may be selected by the base station from available tone spacing schemes for communication. Tone spacing schemes may also be referred to as numerologies.

Abstract: A user equipment (UE) may transmit a random access message to a wireless node using multiple symbols. The random access message may include repetitions of a random access sequence weighted by a spreading code. For example, a random access sequence may be weighted using different elements of the spreading code, where a first repetition may be weighted with a first element and a second repetition may be weighted using a second element. The weighted random access signals may be spread over multiple symbols and transmitted to the wireless node as the random access message. In some cases, a spreading code may include values of one and negative one, may be based on rows of a Hadamard matrix, or may correspond to a number of symbols used to transmit the random access message.

Abstract: Various aspects of the disclosure relate to communicating uplink control information. As one example, a user equipment may send uplink control information to a base station. In some aspects, the number of symbols used to communicate the uplink control information may be based on a link gain associated with the UE and/or based on a payload size of the uplink control information. As another example, the user equipment may send channel information for a number of beams to the base station. In some aspects, the number of beams may be based on the type of channel that is used to send the uplink control information.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may identify two (or more) beamforming directions associated with simultaneous communications to a set of receivers. Each receiver may be associated with a different one of the two beamforming directions. The base station may schedule resources for simultaneous communications with the set of receivers based on the identified two beamforming directions. The base station may schedule simultaneous transmissions to the set of receivers using the scheduled resources.

Abstract: Methods and apparatuses for wireless communication are provided. A transmitting apparatus receives an indication to use multiple subframes to send uplink control information, codes the uplink control information over the multiple subframes based on the indication, and sends the coded uplink control information via the multiple subframes. Sending the coded uplink control information includes transmitting acknowledgement information (ACK) of a current downlink-centric self-contained subframe in an uplink acknowledgement portion of the current downlink-centric self-contained subframe, bundling ACK bits of multiple downlink-centric self-contained subframes and encoding the bundled ACK bits to generate parity acknowledgement bits associated with systematic acknowledgement bits, transmitting the systematic acknowledgement bits in each uplink acknowledgement portion of the multiple downlink-centric self-contained subframes, and transmitting the parity acknowledgement bits associated with the acknowledgement information bits of the multiple downlink-centric self-contained subframes in an uplink-centric self-contained subframe that is sequentially subsequent to the multiple downlink-centric self-contained subframes.

Abstract: Methods, systems, and devices are described for adapting access timing parameters when using DSRC spectrum. A multi-mode device may adapt at least one access timing parameter while operating within the DSRC spectrum. The at least one access timing parameter may be adapted to provide priority to transmissions of DSRC devices using the DSRC spectrum. The multi-mode device may increase a duration of a short inter-frame spacing (SIFS) to be at least equal to a duration of a SIFS used by a DSRC device.

Abstract: Methods, systems, and apparatuses are described for advertising information corresponding to beamforming techniques supported by base stations of a wireless communications system, which in various examples may include analog, digital, and/or hybrid beamforming techniques supported by millimeter wave (mmW) base stations. Advertising of supported beamforming techniques may involve transmissions over a nearby long term evolution (LTE) or another carrier frequency network (e.g., in case of LTE/lower carrier frequency assisted mmW wireless access networks). Alternatively or additionally, advertising may employ broadcasting from a mmW base station, which may include mmW beam sweeps. A UE may receive information corresponding to supported beamforming techniques, and may use the received information to select a particular mmW base station with which to communicate or to determine a transmission strategy for communicating with a particular mmW base station, or both.
