Abstract: A method and apparatus are provided for generating and reporting a reference power headroom report (PHR) for New Radio (NR). A user equipment (UE) decides to report a reference power headroom (PH) for at least one carrier frequency in a transmission time interval (TTI). The UE determines at least one of an index (j) of a target received power of a Physical Uplink Shared Channel (PUSCH) to be transmitted in the TTI and a path loss scaling factor, an index (qd) of a reference signal used for measuring path loss for the carrier frequency, or an index (l) of a power control process used for the carrier frequency. The UE then calculates the reference PH based on one or more of the determined at least one index, and reports, in the TTI, a PHR including the reference PH for the carrier frequency.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may transmit and a user equipment (UE) may receive cloned bandwidth part configuration information. In some aspects, the UE may determine a linkage between a primary bandwidth part and the cloned bandwidth part. In some aspects, the BS may transmit and the UE may receive a downlink control information message identifying the primary bandwidth part to signal a bandwidth part switch for the primary bandwidth part and a first bandwidth part or identifying the cloned bandwidth part to signal the bandwidth part switch for the primary bandwidth part and a second bandwidth part. In some aspects, the UE may perform the bandwidth part switch based at least in part on the downlink control information message. Numerous other aspects are provided.

Abstract: Long term evolution (LTE)/LTE-Advanced (LTE-A) deployments with unlicensed spectrum leverage more efficient LTE communication aspects over unlicensed spectrum, such as over WIFI radio access technology. In order to accommodate such communications, various downlink procedures may be modified in order to handle communications between licensed and unlicensed spectrum with LTE/LTE-A deployments with unlicensed spectrum.

Abstract: Aspects of the disclosure relate to determination of bandwidth, frequencies, or a set one or more of subbands that carries a downlink control channel. In some examples, a set of one or more subbands that carries a downlink control channel may be determined based on a function of a predetermined reference resource location. The predetermined reference resource location may be a set of one or more subbands that carries one or more synchronization signals and a broadcast channel. Other aspects, embodiments, and features are also claimed and described.

Abstract: Uplink control channel transmission in a shared radio frequency spectrum band may be transmitted using different uplink resources UCI based on a format of uplink control information (UCI) to be transmitted in the uplink control channel transmission. Different time resources, frequency resources, or combinations thereof, for the transmission of UCI by a UE may be provided by a base station and selected by the UE based on a UCI format. The resources to be used for UCI transmission may semi-statically configured, or dynamically indicated to a UE. Uplink transmissions may be configured in interlaces of frequency resources, with each interlace having one or more segments, and a base station may configure different segments for transmission of different format UCI. In some cases, different subframes, or different component carriers, may be configured for different formats of UCI.

Abstract: Methods, systems, and devices for wireless communication are described. Different transmission time interval (TTI) durations may be supported and configured to coexist with one another. A set of TTIs with a relatively short duration may overlap in time with longer duration TTIs. Boundaries of TTIs with a relatively short duration may be configured to align with boundaries of relatively longer duration TTIs. For example, TTIs that are a Long Term Evolution (LTE) subframe, an LTE slot, and a duration of two LTE symbol periods may be supported. Two-symbol period TTIs may align with or be embedded within slot-duration TTIs, which, in turn, may align with or be embedded within a subframe. In some examples, one or more symbol periods of a subframe may be designated as a gap between two-symbol TTIs within the subframe, or such symbols may be merged with a two-symbol TTI within the subframe.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques generally support downlink transmissions. For example, a user equipment (UE) may receive a resource configuration for reception of a downlink transmission within a repetition window, the resource configuration including an indicator of a repetition window size for the downlink transmission. The UE may monitor, according to the resource configuration, one or more transmission time intervals (TTIs) of the repetition window for reception of the downlink transmission. In some cases, the downlink transmission may be a grant-free downlink transmission. Here, the UE may attempt to decode the grant-free downlink transmission during the one or more TTIs based at least in part on the repetition window size. Using the described techniques, the UE may efficiently determine one or more decoding parameters for the grant-free downlink transmission, thereby providing benefits in terms of latency reduction, power consumption, etc.

Abstract: Methods, systems, and devices are described for wireless communication. Dedicated frequency resources of a physical random access channel (PRACH) may be designated for large and small frequency hops to facilitate the determination of timing offsets for PRACH transmissions. For instance, a frequency hopping pattern within the PRACH channel having a plurality of single tone transmission may include a first number of hops associated with a first frequency hopping distance (e.g., large frequency hops), and a second number of hops associated with a second frequency hopping distance (e.g., small frequency hops).

Abstract: Methods, systems, and devices for wireless communication are described. In one example, an indication in a first control message in a control region of a first transmission time interval (TTI) identifies a data region of the first TTI. A data region of the second TTI may be identified based on a grant of resources received in a second control message of a second TTI, where the data region of the first TTI and the control region of the second TTI are frequency division multiplexed with the data region of the second TTI. Other examples include a downlink grant at the beginning of a control region and uplink grants at the end of the control region. In other examples, a downlink grant for a user equipment (UE) may include an indication of resources allocated to the UE in that resource block and a second resource block.

Abstract: Methods, systems, and devices for wireless communication are described. A discontinuous reception (DRX) periodicity may be configured to enable monitoring of a reference signal (RS) for RLM procedures. For example, a transmitting device may configure a DRX periodicity for an RS, where the configured DRX periodicity may include a periodicity of discrete transmissions of the RS or a periodicity of a transmission window in which the RS is located. Accordingly, a receiving device may identify the DRX periodicity and monitor radio link quality using the RS based on the DRX periodicity. In some examples, the RS may be transmitted independent of control channel transmissions, and the transmitting device may configure one or more control resource sets for the RS.
