Abstract: A method of wireless communication by a user equipment (UE) without a radio resource control (RRC) connection to a base station includes receiving system information from the base station and transmitting a data communication to the base station over a control plane without establishing an RRC connection with the base station. A UE in an RRC suspended state may transmit a data communication to the base station over a user plane without resuming an RRC connection with the base station. The data communication may comprise data and UE identity information and/or a cause indication. A base station may indicate resources in the system information for the transmission of the data communication information and receive the data communication over the control plane without establishing an RRC connection with the UE or over a user plane without resuming an RRC connection with an RRC suspended UE.

Abstract: Aspects of the present disclosure relate to techniques that may help enable the determination of uplink resource allocation in systems that support dynamic uplink-downlink subframe configurations. An example method generally includes receiving signaling indicating a dynamic uplink-downlink (UL-DL) subframe configuration, determining hybrid automatic repeat request (HARQ) acknowledgment/negative acknowledgment (ACK/NACK) timing based on a reference UL-DL subframe configuration, and determining HARQ resource allocation based on the dynamic UL-DL subframe configuration.

Abstract: A method includes sending communication data from a user equipment (UE) to a base station (eNB) during a random access procedure prior to establishment of a radio resource control (RRC) connection between the UE and the base station. Methods may allow a UE to use a message 1 (Msg1) communication or a message 3 (Msg3) communication to send data to a base station prior to the establishment of the RRC connection between the UE and the base station. Other aspects, embodiments, and features are also claimed and described.

Abstract: Aspects of the disclosure relate to a new radio (NR) single symbol design in which reference signals and data tones are frequency division multiplexed (FDM). In a particular aspect of the disclosure, a different encoding sequence is assigned to each possible value of an information element (IE) such that a minimum distance between encoding sequences corresponding to any pair of possible values is maximized. A symbol corresponding to a particular value of the IE is then transmitted. Here, the symbol is configured according to a sequence selected from a set of sequences corresponding to the particular value of the IE, such that the symbol comprises a plurality of reference signals FDM with a plurality of FDM resource elements.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for uplink power control when at least two separate power control algorithms are utilized for adjusting transmission power of uplink transmissions on one or more uplink channels to one or more access points. The method includes transmitting one or more power headroom report (PHR) based on channel and/or system parameters. In addition, methods are presented to match power control for uplink channels when different power control algorithms are used for those uplink channels. Furthermore, methods are proposed to compensate for a switch between reference signals on which the power control algorithms are based.

Abstract: Aspects of the present disclosure provide techniques for managing unwanted transmissions by a wireless communications device, such as spurious transient transmissions caused by changing a power level of a transmitter. An exemplary method includes determining, based on one or more parameters, an action to reduce an impact of a spurious transmission by the UE, wherein the spurious transmission relates to at least one of changing a transmit power level at the UE or switching one or more radio components at the UE, and taking the determined action to reduce the impact.

Abstract: Various aspects described herein relate to communicating in a wireless network. A resource grant comprising an indicator of whether to transmit a demodulation reference signal (RS) for an uplink control channel or an uplink data channel can be received from a network entity. It can be determined whether to transmit the RS in at least one transmission time interval (TTI) based at least in part on the indicator.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives, by a user equipment (UE) during a first subframe, an indication of a dynamic uplink/downlink (UL/DL) subframe configuration. The apparatus determines an uplink hybrid automatic repeat request (HARQ) timing based on an uplink reference subframe configuration and at least one of the dynamic UL/DL subframe configuration or a downlink reference subframe configuration. The apparatus selects an uplink subframe for communication based on the determined uplink HARQ timing.
