Abstract: Aspects of the present disclosure describe activating a high speed train (HST) configuration for communicating with a cell in a HST based communications environment. 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: The present disclosure may provide technique(s) to configure a UE for asynchronous UL HARQ transmission. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may perform an initial RRC configuration procedure. The apparatus may transmit a first RRC message. The first RRC message may indicate that the UE supports a VoLTE mode. The apparatus may receive a second RRC message from the base station. The second RRC message may configure the UE to operate in VoLTE mode. The apparatus may monitor a CSS for a first uplink grant in first DCI. The first uplink grant may not contain an uplink HARQ ID field. The apparatus may monitor a USS for a second uplink grant in second DCI. The second uplink grant may be associated with asynchronous uplink HARQ, and the second uplink grant may include a HARQ ID field.

Abstract: The present disclosure provides techniques for performing bit-level interleaving for orthogonal frequency-divisional multiplexing (OFDM) symbols across a plurality of code blocks. In some aspects, a transmitting device may dynamically switch between bit-level interleaving and tone-level interleaving for each OFDM symbol based on factors such as number of bits that are carried in each tone, size of each code block, the processing time requirements of the transmitting device and/or the receiving device, or the transmitting device preference.

Abstract: Aspects of the present disclosure provide a method for wireless communication by a wireless communications device in a wireless network, for example, for enabling carrier aggregation (CA) and dual connectivity (DC) under different subframe structures in a 5G system. In certain cases, enabling CA and DC in a 5G system may involve configuring and grouping component carriers based on a numerology criteria associated with each component carrier. The grouped component carriers may then be used to communicate in the wireless network.

Abstract: In order to enable a UE receiving a narrowband signal transmitted using in-band resources to use the LTE reference signals to assist the UE in receiving the narrowband signal using an in-band deployment, a phase rotation employed by the base station may be fixed relative to a known reference position in time. An apparatus for wireless communication at a base station may determine a phase offset for a narrowband signal for transmission using wideband resources, the phase offset having a relationship to a reference point in time and transmit the narrowband signal using the determined phase offset. An apparatus for wireless communication at a UE may receive a narrowband signal having a frequency location within a wideband signal and rotate a symbol of the wideband signal by a per symbol phase offset having a relationship of the phase offset to a reference point in time.

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.
