Abstract: Techniques are described for wireless communication. A method for wireless communication at a user equipment (UE) includes identifying, while the UE is in a connected mode with a network, a radio resource configuration of the UE, selecting a dedicated set of resources for the UE or a common set of resources for a plurality of UEs based at least in part on the identified radio resource configuration, and transmitting a pilot signal to the network using the selected set of resources. Methods for wireless communication at a network access device and a network access device controller are also described.

Abstract: Methods, systems, and devices for wireless communication are described. Methods, systems, and devices provide for different tone spacing schemes for different channels. Methods, systems, and devices also provide for different tone spacing schemes for different stages of communication between a UE and a base station. The base station may indicate, to the UE, the tone spacing scheme in a control channel, a synchronization signal, or a reference signal and the tone spacing scheme may be selected by the base station from available tone spacing schemes for communication. Tone spacing schemes may also be referred to as numerologies.

Abstract: Aspects of the present disclosure provide a wireless device that communicates with another wireless device utilizing self-contained subframes. The wireless device communicates with a scheduling entity utilizing a plurality of self-contained subframes that include a first subframe and a second subframe. Each of the self-contained subframes includes an uplink (UL) portion and a downlink (DL) portion. The wireless device further receives DL control information from the scheduling entity in the DL portion of the first subframe, and transmits UL data that includes a plurality of reference signal bursts to the scheduling entity in the UL portion of the first subframe. The plurality of reference signal bursts are uniformly spaced in at least a portion of the UL portion of the first subframe.

Abstract: A unified frame structure design includes multiple structures to support multiple access requirements. In some aspects, different access requirements may relate to different access terminal categories and/or different applications. In some aspects, different access terminal categories may relate to different performance requirements of different access terminals. In some aspects, the disclosed unified frame structure design could support, for example, and without limitation, at least one of: a low latency mode, a low overhead mode, a low power mode (e.g., for micro-sleep and/or dynamic bandwidth switching), an access terminal with narrowband capability operating in wideband, or ultra-low-latency and nominal multiplexing. Other aspects, embodiments, and features are also claimed and described.

Abstract: Aspects of the present disclosure provide methods and apparatus for beam selection in uplink-based and downlink-based mobility scenarios, for example, for new radio (NR) systems which can improve handover reliability, reduce handover frequency, and improve power efficiency. Certain aspects provide a method for wireless communications by a user equipment (UE). The method generally includes transmitting an uplink reference signal with an indication of a preferred downlink beam and receiving a downlink transmission based, at least in part, on the uplink reference signal.

Abstract: A system and method for mobility tracking of user equipment in a network includes a user equipment. The user equipment includes an antenna for receiving and sending signals to a plurality of network nodes in a network and a processor coupled to the antenna. The processor is configured to broadcast, using the antenna, a pilot signal to advertise the user equipment, receive, using the antenna, a pilot response from a first network node acting as a serving node for the user equipment, and communicate with the network through the serving node. The pilot signal includes a reference sequence for the network nodes to track followed by a payload including information about an identity of the user equipment. In some embodiments, the reference sequence varies based on a state of the user equipment. In some embodiments, the reference sequence is randomly selected.

Abstract: Various aspects of the present disclosure provide for enabling at least one opportunity to transmit mission critical (MiCr) data and at least one opportunity to receive MiCr data in a time division duplex (TDD) subframe during a single transmission time interval (TTI). The single TTI may be no greater than 500 microseconds. The TDD subframe may be a downlink (DL)-centric TDD subframe or an uplink (UL)-centric TDD subframe. How much of the TDD subframe is configured for the at least one opportunity to transmit the MiCr data and how much of the TDD subframe is configured for the at least one opportunity to receive the MiCr data may be adjusted based on one or more characteristics of the MiCr data. The MiCr data may have a low latency requirement, a high priority requirement, and/or a high reliability requirement. Various other aspects are provided throughout the present disclosure.

Abstract: Discovery and synchronization channels are discussed for user-tracking zones in a cellular network. User-tracking zones reduce the mobility tracking burden on the UE and shift the tracking responsibility to the network. This shift allows for UE and network power savings from reduced searching at the UE as well as through efficient paging area tracking and less broadcast signaling. The various aspects provide channel design for initial synchronization and discovery of the user-tracking zones. A single frequency network (SFN) synchronization channel is provided with at least a reference signal for time synchronization and payload information that may include a zone identifier (ID), formatting for a system information transmission request, and resource allocation for the request. The zone ID may be included in the payload or embedded into the reference signal. Facility is also provided for handling zone nodes of different power classes that allows for maintaining the SFN operations.
