A first signal including an HST activate indication to activate a HST configuration can be received from a cell. The HST configuration can be activated based at least in part on the HST activate indication. One or more subsequent signals can be communicated with the cell using the HST configuration based at least in part on the HST activate indication.

Abstract: Aspects of the present disclosure provide techniques and apparatus for performing narrowband physical random access channel (PRACH) procedures in large cells. For example, aspects of the present disclosure provide techniques for narrowband PRACH procedures (e.g., narrowband internet of things (NB-IoT)) to accommodate larger RTTs (e.g., up to 100 km). In some cases, supporting larger RTTs may involve a base station altering its PRACH processing by performing a two-step process of, first, obtaining a frequency domain phase offset based on an uplink signal from a UE, which provides a fractional delay and, second, performing a time domain correlation for different timing hypotheses to determine a timing offset based on the uplink signal. Supporting larger RTTs may also involve enabling a new NPRACH format that may coexist with legacy 3.75 kHz resources.

Abstract: Certain aspects of the present disclosure generally relate to wireless communications. In some aspects, a wireless communications device may employ different power control loops, associated with different power control reference points, for uplink transmissions that use different uplink waveforms. In some aspects, a wireless communications device may generate and transmit a first type of PHR, associated with a DFT-s-OFDM-based type of uplink transmission, and/or a second type PHR associated with a CP-OFDM-based type of uplink transmission. In some aspects, a wireless communications device may selectively send a HARQ re-transmission using a particular uplink waveform based at least in part on information indicating whether the HARQ re-transmission is permitted to use an uplink waveform that is different from another uplink waveform used for a prior corresponding HARQ transmission or HARQ re-transmission. Numerous other aspects are provided.

Abstract: Wireless communications systems and methods related to random access and uplink (UL)-based mobility are provided. A first wireless communication device transmits a first signal carrying a random access sequence and a data. The first wireless communication device receives a second signal from a second wireless communication device in response to the first signal. For random access, the data in the first signal includes at least one of an identifier of the first wireless communication device or a connection request, and the second signal includes at least one of timing advance information or a contention resolution. For UL-based mobility, the data in the first signal includes at least an identifier of the first wireless communication device, and the second signal includes at least an acknowledgement for the first signal or paging information associated with the first wireless communication device.

Abstract: Various aspects described herein relate to techniques for random access based on scalable signature design in wireless communications systems. A method, a computer-readable medium, and an apparatus are provided. In an aspect, the method may include randomly choosing an array of source symbols, wherein the array has one or more scalable dimensions based on at least one of a capacity requirement or a coverage requirement of a random access channel (RACH), encoding the array of source symbols into a codeword for a RACH signature, mapping the codeword to a serial concatenation of orthogonal or quasi-orthogonal sequences to define the RACH signature, and transmitting the RACH signature within a RACH slot. The techniques described herein may apply to different communications technologies, including 5th Generation (5G) New Radio (NR) communications technology.

Abstract: Various aspects described herein are related to communicating feedback communications received over multiple component carriers (CCs) in wireless communications. The communications can be received from a serving node over the multiple CCs configured in carrier aggregation or multiple connectivity. One or more of the multiple CCs can be determined for transmitting feedback regarding the communications received over at least one CC of the multiple CCs, wherein the one or more of the multiple CCs are selected for transmitting the feedback based at least in part on a transmission time interval (TTI) duration for the at least one CC. Feedback related to receiving the communications from the serving node over the at least one CC can be transmitted over the one or more of the multiple CCs.
