Abstract: Some aspects of the disclosure provide for wireless communication systems in which scheduling information is transmitted to a scheduled entity to schedule transmission of uplink feedback control information by the scheduled entity. The feedback control information may be transmitted in short uplink control bursts or long uplink bursts. Selection between short uplink control bursts and long uplink bursts may be based on power headroom at the scheduled entity, interference in the short uplink control burst or the long uplink burst, loading of the short uplink control burst or the long uplink burst or processing capability of the scheduled entity.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communication. An exemplary method generally includes receiving an indication of a modulation and coding scheme (MCS) to use for transmitting information, wherein the indication of the MCS indicates an MCS index value corresponding to an entry in an MCS lookup table, determining, based on the MCS index value, a transport block size (TBS) to use for transmitting the information, wherein determining the TBS comprises receiving an explicit indication of the TBS to use for transmitting the information, and transmitting the information using the MCS and TBS.

Abstract: An apparatus may utilize an air interface to transmit and/or receive a transmission during a first TTI that includes a second set of data overriding a first set of data scheduled for transmission during the first TTI. The air interface may further be utilized to transmit and/or receive a transmission after a duration of time that is less than a total time duration of the first TTI that includes a control channel that is at least partially embedded in a data portion of a subframe. The control channel may include an override indicator configured to indicate that the first set of data scheduled for transmission during the first TTI is overridden by the second set of data having the higher priority. The override indicator may be transmitted after the second set of data is transmitted. The one or more additional TTIs may be after the first TTI.

Abstract: Methods, systems, and devices for wireless communications are described that provide for a location indicator transmission that may indicate a location of control channel resources that are to be monitored by a user equipment (UE) for control channel transmissions. A UE may receive the location indicator, and monitor the indicated control channel resources to receive downlink control information with an allocation of shared channel resources for the UE. The location indicator may include one or more parameters that allow a UE to receive the control channel transmissions according to a single decoding hypothesis. The location indicator may include one or more of a valid period of the location of the control channel transmissions, an interval at which control channel transmissions may be transmitted, an aggregation level used for the control channel transmissions, an index that identifies a first control channel element of the control channel transmissions, or combinations thereof.

Abstract: Generally, the described techniques provide for a user equipment (UE) generating a scheduling request (SR) for a set of data for an uplink transmission from the UE to a base station. The UE may determine whether the SR for the set of data is associated with a grant-free configuration for the UE. The grant-free configuration may indicate a set of time-frequency resources that the UE may use to transmit the set of data. The UE may transmit to the base station an indication of whether the SR is associated with the grant-free configuration. If the SR is associated with a grant-free configuration for the UE, the UE may use the corresponding resources to transmit the set of data to the base station, and the base station may then decode the data based on having received the indication of the resources by way of the grant-free configuration.

Abstract: Methods and apparatus are provided for selecting a code type. A type of code is selected from a set of code types to use as an inner code for a concatenated encoding scheme for encoding information bits of a channel, wherein the selection is based on one or more channel coding parameters including a false alarm detection objective for the channel. A codeword is generated by encoding the information bits using the type of codes selected as the inner code and an outer code. The generated codeword is transmitted.

Abstract: Various aspects provide for communicating a first set of broadcast reference signals (RSs) in a first subframe that includes a synchronization (SYNC) channel and communicating a second set of broadcast RSs in a second subframe that follows the first subframe. The second subframe may immediately follow the first subframe. A portion of the SYNC channel may include information indicating a configuration of broadcast RSs in one or more other subframes. The broadcast RSs may be configured for timing-error estimation, frequency-error estimation, and/or channel estimation. Additional and alternative aspects, embodiments, and features are also provided herein.

Abstract: An apparatus may configure x subframes with a subslot configuration that includes y subslots, y being greater than x. In an aspect, each subslot of the y subslots may include a first portion having one or more symbols for carrying at least one of data or control information, a second portion having a gap, and a third portion for carrying ACK/NACK information associated with the first portion. In an aspect, the second portion may be between the first portion and the third portion. In an aspect, the second portion and the third portion may include at most one symbol. The apparatus may send information indicating the subslot configuration to at least one neighboring base station. The apparatus may communicate content with a user equipment (UE) during at least one of the y subslots.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a transmitting device may be configured to transmit a transport block in a set of transmission time intervals (TTIs) of a repetition window to improve the chances that the transport block is received by a receiving device. In some cases, however, the transport block may not be available to be transmitted in the repetition window until after a first TTI of the repetition window. In such cases, a transmitting device may use the techniques described herein to identify appropriate configurations for transmitting the transport block in the repetition window. For example, the transmitting device may identify an adjusted redundancy version sequence to use for transmitting the transport block in the repetition window or the transmitting device may adjust a repetition window based on a TTI in which the transport block is available to be transmitted.

Abstract: Methods, systems, and devices for wireless communication are described that provide for generation of an encoded transport block (TB) that includes a number of systematic code blocks (CBs) and a number of parity CBs. The systematic CBs may be transmitted to a receiver, and the receiver may attempt to decode the systematic CBs. In some cases, one or more parity CBs may be transmitted with the systematic CBs, and the systematic CBs may be successfully decoded even in the event that one or more of the systematic CBs are not successfully received. In some cases, a receiver may provide feedback that requests that additional CBs be transmitted to decode the systematic CBs that were received, and it is not necessary to retransmit the missing systematic CBs. In some cases, a quantized value of a number of additional CBs needed to decode the TB may be transmitted.
