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: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) may be configured to transmit a transport block multiple times 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, the UE may use the techniques described herein to identify appropriate configurations for transmitting the transport block in the repetition window. In particular, the UE may determine whether to use a fixed repetition window or a sliding repetition window for transmitting the transport block based on various factors in an attempt to satisfy latency and reliability constraints associated with the transport block.

Abstract: Certain aspects of the present disclosure relate generally to wireless communications systems, and more particularly, to improving reliability of a physical downlink control channel (PDCCH) transmission. In some cases, improved reliability may be achieved by increasing a number of CCEs available for the PDCCH transmission and/or transmitting multiple copies of the PDCCH transmission in frequency.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may identify that a last resource block of a resource allocation for a physical downlink shared channel (PDSCH) is in a last allocable resource block group (RBG); and determine whether one or more additional resource blocks, subsequent to the last resource block, are included in the resource allocation for the PDSCH based at least in part on at least one of a reference signal type associated with the PDSCH, a quantity of the one or more additional resource blocks, or the DCI format associated with the PDSCH. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques and apparatus for signaling channel preemption indications that enable a user equipment (UE) of a first type to take one or more actions on resources that are re-allocated to an UE of a second type. An exemplary method generally includes determining that resources allocated for a scheduled transmission by a first user equipment (UE) of a first type overlaps with uplink channel resources allocated to a second UE of a second type. The method also includes signaling, based on the determination, an uplink preemption indication (ULPI), to the second UE, that identifies at least some of the overlapping resources.

Abstract: Systems, apparatuses, and methods for computing transport block size (TBS) for channels with shortened transmission time interval (sTTI). An initial size may be determined based on one or more TBS tables. The initial size may be scaled by a factor associated with an sTTI channel. A TBS table is selected based on the one or more TBS tables. The scaled size may be rounded based on the selected TBS table to generate a TBS for the sTTI channel.

Abstract: Wireless communications systems and methods related to over-the-air uplink-downlink (UL-DL) reciprocity calibration. A central unit transmits downlink (DL) calibration reference signal (RS) and a calibration request. The central unit receives, in response to the calibration request, a first uplink (UL) calibration RS and a first DL channel estimate associated with a first transmission point (TP) and a first wireless communication device. The central unit transmits a DL coordinated multipoint (CoMP) joint transmission signal according to an uplink-downlink (UL-DL) reciprocity calibration. The UL-DL reciprocity calibration is based on at least a first UL channel estimate based on the first UL calibration RS, the first DL channel estimate, a second UL channel estimate associated with a second TP and the first wireless communication device, and a second DL channel estimate associated with the second TP and the first wireless communication device.

Some wireless communications systems support mobile broadband (MBB) communications and low latency communications. To accommodate low latency communications, a base station may identify resources allocated for MBB communications, and the base station may reassign (or puncture) these resources for low latency communications. The base station may transmit an indication of the reassigned (or punctured) resources to one or more user equip- ment (UEs). The base station may transmit an indication of the reassigned re- sources in a transmission time interval (TTI) that is subsequent to a TTI reas- signed (or punctured) for low latency communications (e.g., a post indication). The base station may transmit the post indication in a retransmission grant of a physical downlink control channel (PDCCH) or in downlink control informa- tion (DCI) of a PDCCH.
