Abstract: An apparatus may determine a cyclic prefix (CP) length for a signal for a communication link based on a dynamic indication. The CP length may be determined from a plurality of CP lengths. The apparatus may communicate the signal using the determined CP length. Determining the CP length may be further based on at least one of a modulation and coding scheme, a subcarrier spacing, a service type, a communication link direction, a rank number, a type or a capability of the node, or a number of nodes scheduled in the same transmit time interval. Determining the CP length may include determining a first CP length for a first symbol of a plurality of symbols in the TTI, and determining a second CP length, different than the first CP length, for a second symbol of the plurality of symbols in the TTI. Various additional and alternative aspects are described herein.

Abstract: Techniques for transmission of Ultra-Reliable Low-Latency Communications (URLLC) data over Time Division Duplex (TDD) using a URLLC configuration for a TDD subframe are disclosed. The techniques include determining that data scheduled for transmission using a TDD band over a TDD subframe includes Ultra-Reliable Low-Latency Communications (URLLC) data, and in response, utilizing a URLLC subframe configuration for the TDD subframe. The URLLC subframe configuration includes downlink intervals and uplink intervals.

Abstract: An apparatus may receive, from a scheduling entity, sidelink grant information in a downlink control channel. After receiving the grant information in the downlink control channel, the apparatus may transmit a request-to-send (RTS) signal comprising an indication of a requested duration of time to reserve a sidelink channel for sidelink data. If the sidelink channel is available for the requested duration of time, the apparatus may receive a clear-to-send (CTS) signal configured to indicate an availability of the sidelink channel for the requested duration of time. Subsequently, the apparatus may communicate, with another apparatus different from the scheduling entity, the sidelink data using the sidelink channel during the requested duration of time. Afterwards, the apparatus may communicate acknowledgment information corresponding to the communication of the sidelink signal with the other apparatus. Various additional and alternative aspects are described herein.

Abstract: The present disclosure provides for adaptive resource management in new radio operations that favors the usage of resources for pilot signals and channel estimation in the transition slots of a slot burst, and the transmission of data in the subsequent slots of the slot burst. A device such as a user equipment (UE) and/or a base station may determine that the UE is operating in a transition state. The device may adapt a first numerology including a first number of symbols per slot used for transmission in the transition slots during the transition state, to a second scaled numerology including a second number of symbols per slot used for transmission in the subsequent slots after the transition state. A ratio of reference signal symbols to data symbol symbols may be greater in the transition slots than in the subsequent slots.

Abstract: Wireless communications systems and methods related to the reduction in a probability of collision for grant-less transmissions from internet of everything (IOE) devices while not increasing search complexity at a base station are disclosed. An IOE device randomly selects a first access resource from a common pool that the base station searches to initiate a transmission. If a metric associated with the data transmission is predicted to exceed a threshold, the IOE device also requests a second access resource from a reserved access pool from the base station, that the base station does not search. The IOE includes the request in the data transmission. The base station and the IOE device switch to the second access resource after the base station identifies an available resource from the reserved access pool and the IOE device completes the data transmission using the second access resource.

Abstract: A wireless device may transmit a data block based on a low latency operational mode. The device may then transmit a number of redundancy versions of the data block prior to determining whether an acknowledgement (ACK) has been received. In some examples the ACK may be an augmented ACK, which may be based on the number of redundancy versions received prior to successfully decoding the data block, and which may include an additional resource request. In some examples, the device may select an updated modulation and coding scheme (MCS) based on the augmented ACK. In some examples, the device may increase a number of frequency resources (e.g., component carriers) used for transmission based on the augmented ACK.

Abstract: Certain aspects of the present disclosure relate to techniques and apparatus for efficient support of connected discontinuous reception (C-DRX) by using a wireless device (e.g., a user equipment (UE)) with a second receiver. A wireless device with two receivers may place one receiver in a low power mode and take the receiver out of the low power mode in response to a signal received from a serving base station (BS) of the wireless device. A BS may direct a wireless device to enter a low power DRX (LP-DRX) mode or enhanced DRX mode having longer low power cycles than a non-enhanced DRX mode, and the wireless device may place a primary receiver in a low power mode in response to the directive from the BS. Other aspects, embodiments, and features are also claimed and disclosed.

Abstract: Channel state information (CSI) feedback in long term evolution (LTE) and LTE-Advanced (LTE-A) networks including contention-based shared unlicensed spectrum is disclosed in which a user equipment (UE) identifies at least one carrier utilizing a contention based radio frequency spectrum. The UE detects a transmission signal indicative of clear channel assessment (CCA) result information for the carrier and determines whether a reference signal for channel state information measurement is present in a subframe based on the detected transmission signal. The UE would transmit a measurement report based on this presence determination of the reference signal.
