Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may receive a plurality of resource blocks of a short channel mapped using a short resource element group (sREG) to short control channel element (sCCE) mapping. The short channel may be a short physical downlink control channel (sPDCCH) or a short physical downlink shared channel (sPDSCH). The wireless communication device may process the short channel using the plurality of resource blocks. The plurality of resource blocks may be bundled into a set of resource block bundles based at least in part on the sREG-to-sCCE mapping.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may identify a potential collision between a scheduled legacy transmission time interval (TTI) communication and a scheduled shortened TTI (sTTI) communication, the legacy TTI communication having a legacy TTI duration that is longer than an sTTI duration associated with the sTTI communication. The apparatus may determine whether the legacy TTI communication is within a threshold time of being transmitted. The apparatus may transmit at least one of the sTTI communication, the legacy TTI communication, or any combination thereof, based at least in part on the determination.

Abstract: Aspects of the present disclosure describe communicating control data based on reference signals in wireless communications. A timeline for transmitting uplink communications can be determined, where the timeline can relate to whether to process downlink communications based on at least one of a first type of reference signal (RS) or a second type of RS, a length or number of symbols in the reference signal, or a timing advance.

Abstract: In an aspect, an apparatus may receive content to be transmitted and generate a first turbo encoded codeword from the content through use of a first turbo encoder. The apparatus maybe further configured to generate an interleaved codeword based on the first turbo encoded codeword through use of an interleaver, generate a second turbo encoded codeword from the interleaved codeword through use of a second turbo encoder, and transmit at least a portion of the second turbo encoded codeword. In an aspect, an apparatus may receive data including outer turbo encoded, interleaved, inner turbo encoded content. The apparatus may generate a first decoded instance of the data, generate a de-interleaved instance of the data based on the first decoded instance of the data, generate a second decoded instance of the data from the de-interleaved instance of the data, and perform a CRC on the second decoded instance of the data.

Abstract: The present disclosure may enable a buffer to accommodate HARQ processes for transmissions with different TTIs when the UE is configured for legacy communications and ULL communications. The apparatus may allocate a first number of HARQ IDs to a first portion of a buffer, the first number of HARQ IDs being associated with a first transmission TTI HARQ process. In addition, the apparatus may allocate a second number of HARQ IDs to a second portion of the buffer. In an aspect, the second number of HARQ IDs may be associated with a second TTI HARQ process. In addition, the first portion and second portion may not change a total buffer size. The apparatus may also receive a HARQ response associated with a HARQ ID allocated to the first portion or the second portion.

Abstract: The present disclosure provides a unique control region that is mapped to each data region for DL DMRS transmissions. In addition, the present disclosure provides an updated DCI format that may include DL DMRS transmissions. The apparatus may receive a first content during a first TTI. In an aspect, the content may include at least a control region which includes a DMRS. In addition, a location of the DMRS may be defined by either a closed-loop precoding structure or an open-loop precoding structure. Furthermore, the duration of the first TTI may be shorter than 1 ms. The apparatus may demodulate the control region based at least on the DMRS.

Abstract: Certain aspects of the present disclosure provide techniques that may be used to help enable low latency communications between a user equipment (UE) and a base station (BS) using quick uplink channels that enable a reduced transmission time interval (TTI). An example method generally includes identifying a plurality of slots in a subframe, receiving a resource configuration for an uplink channel, wherein the resource configuration is associated with a first slot of the plurality of slots, determining a resource for transmitting the uplink channel in a second slot of the plurality of slots, wherein the resource is determined based on the resource configuration associated with the first slot of the plurality of slots, and transmitting the uplink channel in the second slot using the determined resource.

Abstract: Aspects are presented which enable a UE to determine a supplementary uplink (SUL) configuration for an uplink cancellation indication (ULCI) for cancelling uplink communications in SUL. The UE receives from a base station a first configuration associated with a first block of an ULCI and associated with at least one of a SUL carrier a non-supplementary uplink (NUL) carrier in a cell. The base station configures the UE with a second configuration associated with a second block of the ULCI and associated with a SUL carrier in the cell, and the UE determines the second configuration. The UE monitors the ULCI based on the first configuration and the second configuration.

Abstract: In an aspect, a sidelink device may reserve a first sidelink resource for transmission of a first positioning reference signal (PRS) by the sidelink device. The sidelink device may reserve at least one further sidelink resource for transmission of at least one further PRS by at least one further sidelink device, wherein the at least one further sidelink resource occurs within a first time threshold of the first sidelink resource.
