Abstract: Certain aspects of the present disclosure relate to methods and apparatus for implementing one or more antenna diversity schemes using communications systems operating according to 5G technologies. For example, techniques and apparatus may be provided for employing Alamouti encoding in a time domain for one or more portions of a plurality of modulated symbols associated with a first signal to be transmitted by a first antenna or a second signal to be transmitted by a second antenna to create a first plurality of encoded symbols or a second plurality of encoded symbols with tone-wise Alamouti in the frequency domain.

Abstract: A user equipment (UE) may perform a random access procedure to synchronize with a network for uplink and/or downlink communication. The UE may transmit a first type of random access transmission that includes transmitting a preamble or a second type of random access transmission that includes transmitting a preamble and a random access message. The second type may result in reduced delay but may have lesser SNR tolerance than the first type. In some aspects, the UE may determine whether to transmit the first type or the second type, and may transmit the first type or the second type in a random access channel portion of a slot. The random access channel portion of the slot may be occupied by portions of either the first type of random access transmission or the second type of random access transmission, thereby enabling flexible utilization of multiple types of random access procedure.

Abstract: A configurable new radio (NR) uplink (UL) transmission may use transmit diversity. A user equipment (UE) may identify an uplink transmission of at least one stream as using one of cyclic prefix orthogonal frequency division multiplexing or discrete Fourier transform spread orthogonal frequency division multiplexing. The UE may apply a precoding matrix to the at least one identified stream. The precoding matrix changes over time. The precoding matrix may change based on closed loop feedback, a precoding cycling pattern, and/or a code division multiplexing group. The UE may transmit the at least one identified stream from multiple antennas according to the applied precoding matrix.

Abstract: A new design for an uplink control channel is provided. A User Equipment (UE) determines, based on a tone mapping pattern from a plurality of tone mapping patterns for an uplink control channel, resources for transmitting the uplink control channel, and transmits the uplink control channel using the determined resources. A Base Station (BS) determines a tone mapping pattern from a plurality of tone mapping patterns for an uplink control channel, and transmits information regarding the determined tone mapping pattern to at least one UE. The BS receives the uplink control channel based on the tone mapping pattern.

Abstract: NB wireless communication involves numerous challenges. A limited frequency dimension may need to be shared by multiple users. At times, large data transmissions, including multiple TBs of data may be transmitted using NB communication, and it may be important that each TB be successfully received by the users. The apparatus may transmit data comprising a plurality of TBs in a narrow band communications system, including repeating a transmission of the plurality of TBs, using any of a number of repetition patterns. The apparatus may use error correction encoding across multiple TBs. The transmission may be a single cell transmission or a multi-cell transmission.

Abstract: Aspects of the present disclosure provide techniques for design of synchronization signals for narrowband operation, which can be used for stand-alone/in-band/guard-band deployment. An example method is provided for operations which may be performed by a base station (BS). The example method generally includes generating a primary synchronization signal (PSS) utilizing a first code sequence and a cover code applied to the first code sequence over a first number of symbols within one or more subframes, generating a secondary synchronization signal (SSS) based on a second code sequence over a second number of symbols within one or more subframes, and transmitting the PSS and the SSS in the first and second subframes to a first type of a user equipment (UE) that communicates on one or more narrowband regions of wider system bandwidth.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for sounding reference signal (SRS) management for a line-of-sight multiple-input multiple-output (LSM) mode. A receiving device may receive a configuration of a persistent or semi-persistent SRS resource set that configures a first number of SRS ports for a full spatial sounding mode. The receiving device may transmit a SRS on a partial sounding resource subset of the SRS resource set, the partial sounding resource subset corresponding to a partial sounding LSM mode. A transmitting device such as a base station may performing phase ramp interpolation for the partial sounding LSM mode to estimate a LSM channel between the base station and the first receiving device.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may transmit, to a second wireless device, a message indicating a capability of the first wireless device to support full-duplex line-of-sight (LOS) multiple-input multiple-output (MIMO) communications. The first wireless device may receive, from the second wireless device, control signaling indicating an uplink channel resource allocated for one or more uplink communications, a downlink channel resource allocated for one or more downlink communications, a first set of LOS MIMO transmission modes for the one or more uplink communications, and a second set of LOS MIMO transmission modes for the one or more downlink communications. The uplink channel resource may at least partially overlap with the downlink channel resource in time, frequency, or both. The first wireless device may communicate the one or more uplink communications and the one or more downlink communications based on the control signaling.
