Abstract: Certain aspects of the present disclosure relate to methods and apparatus for generating and communicating reference signals. Certain aspects provide a method for communicating reference signals. The method includes selecting a demodulation reference sequence (DMRS) of a plurality of DMRSs for transmission in a synchronization signal block (SSB) based on a half-frame in which the SSB is transmitted. The method further includes transmitting the selected DMRS in the SSB.

Abstract: The present disclosure provides user equipment power consumption and secondary cell (SCell) activation latency reductions in wireless communication systems. For example, a UE may determine that a secondary cell activation condition has been satisfied. The UE may further transition to a secondary cell activated state based on determining that the secondary cell activation condition has been satisfied, the secondary cell activate state corresponding to a dormant SCell state. The UE may operate at least in the dormant SCell state.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus relating to a long uplink burst channel design. In certain aspects, the method includes determining, based on a hopping pattern, a first set of frequency resources available for transmitting uplink control information (UCI) within a first portion of a transmission time interval (TTI) and a second set of frequency resources available for transmitting UCI within a second portion of the TTI. The method also includes transmitting the UCI using the determined first set of frequency resources and the second set of frequency resources.

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.
