Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives a discovery signal transmitted from a connection point (CP) via a directional beam. The discovery signal may include first information (including beam sweep configuration information) related to the CP. The apparatus then transmits an association signal to the CP based on the beam sweep configuration information and monitors for a resource grant from the CP based on the transmitted association signal. Alternatively, the apparatus transmits a discovery signal via a directional beam to a user equipment (UE). The discovery signal may include first information (including beam sweep configuration information) related to the apparatus. The apparatus then receives an association signal from the UE based on the beam sweep configuration information and determines a resource grant for communicating with the UE based on the received association signal.

Abstract: Various aspects described herein relate to techniques for synchronization channel design and signaling in wireless communications systems (e.g., a 5th Generation (5G) New Radio (NR) system). In an aspect, a method includes identifying a frequency band supported by a user equipment (UE), identifying one or more frequency locations based on the identified frequency band, and the one or more frequency locations are a subset of synchronization raster points used for synchronization signal transmission. The method further includes searching for at least one synchronization signal based on the one or more identified frequency locations.

Abstract: Aspects of the disclosure provide for a thin control channel structure that can be utilized to enable multiplexing of two or more data transmission formats. For example, a thin control channel may carry information that enables ongoing transmissions utilizing a first, relatively long transmission time interval (TTI) to be punctured, and during the punctured portion of the long TTI, a transmission utilizing a second, relatively short TTI may be inserted. This puncturing is enabled by virtue of a thin channel structure wherein a control channel can carry scheduling information, grants, etc., informing receiving devices of the puncturing that is occurring or will occur. Furthermore, the thin control channel can be utilized to carry other control information, not being limited to puncturing information. Other aspects, embodiments, and features are also claimed and described.

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: The present disclosure describes various examples of a method, an apparatus, and a computer readable medium for multi-state discontinuous reception (DRX) in wireless communications. For example, one of the methods described may include identifying, by a user equipment (UE), at least two states in connected mode, determining, by the UE, one or more triggers for transitioning between the at least two states, and transitioning, by the UE, from a first state of the at least two states to a second state of the at least two states in response to a determination of the one or more triggers. In an aspect, the transitioning comprises transitioning between cross-slot scheduling and same-slot scheduling, or between a narrow bandwidth and a wide bandwidth, or between a larger periodicity and a smaller periodicity for monitoring.

Abstract: A unified frame structure design includes multiple structures to support multiple access requirements. In some aspects, traffic communicated according to one structure may puncture traffic communicated according to another structure. In some aspects, an indication of the puncturing may be communicated. In some aspects, communication based on the unified frame structure may use a code block-level acknowledgement. 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.

Abstract: Aspects of the present disclosure provide a time division duplex (TDD) subframe structure that supports both single and multiple interlace modes of operation. In a single interlace mode, control information, data information corresponding to the control information and acknowledgement information corresponding to the data information are included in a single subframe. In a multiple interlace mode, at least one of the control information, the data information corresponding to the control information or the acknowledgement information corresponding to the data information is included in a different subframe. Both single and multiple interlace modes can be multiplexed together within the TDD subframe structure.

Abstract: A system and method for low latency acknowledgements includes a first communication unit receiving a data message from a second communication unit on a data channel, decoding the data message, and transmitting, in response to the decoding, an acknowledgement signal on a control channel to the second communication unit. The acknowledgement signal has a partially decodable structure. Transmitting the acknowledgement signal further includes transmitting multiple repetitions of a same time domain waveform during one symbol period. In some embodiments, transmitting the acknowledgement signal further transmitting K repetitions of a same time domain waveform with a frequency domain characteristic consisting of one non-zero tone for every K tones, K being a positive integer. In some embodiments, the acknowledgement signal is processable by the second communication unit using a first N out of the K repetitions, N being a positive integer less than K.
