Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may identify an uplink/downlink (UL/DL) configuration that defines subframe configuration options for each subframe of a frame. For example, the UL/DL configuration may establish parameters for time division duplexing (TDD) operation between a base station and a user equipment (UE). The wireless device (e.g., the UE or base station) may determine a constraint for a subframe of the frame based on the UL/DL configuration and then determine an adaptive subframe configuration based on the constraint. The adaptive subframe configuration may include one or several downlink symbol periods and one or several uplink symbol periods. The wireless device may then communicate during the subframe according to the adaptive subframe configuration rather than the original UL/DL configuration; and, because the adaptive subframe may be constrained by the identified UL/DL configuration, the communication during the subframe may avoid disruption to UEs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a resource allocation indicating a set of transmission tones comprising a set of data tones and a set of peak reduction tones (PRTs), wherein the resource allocation indicates locations for the set of data tones and locations for the set of PRTs within a particular bandwidth, wherein the locations for the set of PRTs are arranged relative to the locations for the set of data tones according to a PRT sequence, and wherein the PRT sequence comprises a plurality of contiguous PRTs arranged relative to a plurality of contiguous data tones or a pseudo-random pattern generated using a pseudo-random number generator; and transmit a data transmission using a waveform based at least in part on the resource allocation. Numerous other aspects are provided.

Abstract: Handling of asynchronous multi-carrier is discussed. In new radio (NR) fifth generation (5G) networks, the potential for provision of multi-carrier operations (e.g., carrier aggregation (CA), dual connectivity (DC), etc.) that include asynchronous component carriers (CCs) has been proposed. However, because of the asynchronous relationship network entities, such as base stations and user equipments (UEs) will manage the asynchronous CCs by obtaining timing offset information, either through derivation or direct signaling, and determining a subframe correspondence based on the timing offset relative to a reference CC. By determining the subframe correspondence to the reference CC, the base stations and UEs can accurately map communications over the asynchronous CCs to the appropriate subframes across CCs.

Abstract: Symbol alignment and power scaling are provided for different length transmission time intervals (TTIs) within predefined boundaries, such as boundaries of a slot of a subframe. Described techniques provide for identifying time and/or frequency resources for one or more TTIs and allocating such resources based on a location within a subframe, pilot signals that may be transmitted using the resources, other processing timelines, or any combination thereof. In some cases, a power allocation for symbols within a TTI may be determined based on the allocated resources for the TTI. Frequency hopping patterns and power scaling for three-symbol TTIs are also provided.

Abstract: Aspects of the present disclosure relate to wireless communications and, more particularly, to synchronization for standalone long term evolution (LTE) broadcast. In one aspect, a method is provided which may be performed by a wireless device such as a user equipment (UE). The method generally monitoring, within anchor subframes occurring at a first periodicity, for synchronization signals of a first type, obtaining an indication of one or more unicast subframes scheduled to occur between anchor subframes, and obtaining an indication of one or more broadcast subframes scheduled to occur between anchor subframes.

Abstract: Described techniques provide for communications using multiple different transmission time intervals (TTIs) while in a configured DRX mode that allows efficient scheduling and allocation of resources, and relatively efficient power usage at a user equipment (UE). In some cases, two or more available TTIs for transmissions between a base station and a UE may be identified, and a DRX cycle configured based at least in part on the available TTIs. During monitoring periods of a configured DRX cycle for a first TTI, the UE may be configured to monitor for control signal transmissions associated with a different TTI duration. In some cases, resources for a shorter TTI may be allocated using a two-stage grant. In some cases, multiple component carriers may be configured for one or more different TTIs, and one component carrier may be used to cross schedule resources on other component carriers.

Abstract: Various aspects described herein relate to communicating in a wireless network. A transmission time interval (TTI) for an uplink control channel transmission within a subframe is determined, wherein the TTI comprises of a number of symbols which are a subset of a plurality of symbols in the subframe.

Abstract: Methods, systems, and devices for wireless communication are described that support sounding reference signal (SRS) transmission in low latency wireless transmissions. A set of shortened transmission time intervals (sTTIs) for uplink transmissions of a first wireless service may be identified; the set of sTTIs located within subframe time boundaries of a subframe of a second wireless service with a longer TTI than the sTTIs. Two or more sTTIs within the set of sTTIs may be used for SRS transmissions within the subframe time boundaries.

Abstract: Wireless devices may exchange data related to multiple available random access procedures for network access. A random access procedure of the available random access procedures may be selected, and a random access message transmitted based on the selected random access procedure. Available random access procedures may include procedures that provide for a different number of random access messages or that are for use in communications having different transmission time intervals (TTIs). The available random access procedures may include a contention-based random access procedure, in which an initial random access message may include a payload. In some examples, a number of random access resources may be provided within different frequency resources available to provide efficient usage of a channel bandwidth.
