BACKGROUND

Aspects of the present disclosure relate generally to wireless communication networks, and more particularly, to enable repetitive transmissions on an uplink communication channel in a new radio wireless communication system.

Wireless communication networks are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be multiple-access systems capable of supporting communication with multiple users by sharing the available system resources (e.g., time, frequency, and power). Examples of such multiple-access systems include code-division multiple access (CDMA) systems, time-division multiple access (TDMA) systems, frequency-division multiple access (FDMA) systems, orthogonal frequency-division multiple access (OFDMA) systems, and single-carrier frequency division multiple access (SC-FDMA) systems.

These multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different wireless devices to communicate on a municipal, national, regional, and even global level. For example, a fifth generation (5G) wireless communications technology (which can be referred to as new radio (NR)) is envisaged to expand and support diverse usage scenarios and applications with respect to current mobile network generations. In an aspect, 5G communications technology can include: enhanced mobile broadband addressing human-centric use cases for access to multimedia content, services and data; ultra-reliable-low latency communications (URLLC) with certain specifications for latency and reliability; and massive machine type communications, which can allow a very large number of connected devices and transmission of a relatively low volume of non-delay-sensitive information. As the demand for mobile broadband access continues to increase, however, further improvements in NR communications technology and beyond may be desired.

For example, for NR communications technology and beyond, enabling low latency communications even during instances of insufficient uplink coverage is necessary. Thus, improvements in wireless communication operations may be desired.

SUMMARY

The following presents a simplified summary of one or more aspects in order to provide a basic understanding of such aspects. This summary is not an extensive overview of all contemplated aspects, and is intended to neither identify key or critical elements of all aspects nor delineate the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form as a prelude to the more detailed description that is presented later.

In accordance with an aspect, a method includes enabling repetitive transmissions on an uplink communication channel for wireless communications. The described aspects include receiving, by a user equipment (UE), an activation message for repetition-based uplink communications from a network entity, the activation message including one or more transmission parameters indicating at least a duration for transmissions on an uplink communication channel and an uplink shortened Transmission Time Interval (sTTI) pattern for the transmissions on the uplink communication channel. The described aspects further include performing, by the UE, repetitive transmissions on the uplink communication channel for the duration indicated by the one or more parameters in the activation message (and/or a configuration message), the repetitive transmissions being configured based on the uplink sTTI pattern.

In an aspect, an apparatus for enabling repetitive transmissions on an uplink communication channel for wireless communications may include a transceiver, a memory; and at least one processor coupled to the memory and configured to receive, by a UE, an activation message for repetition-based uplink communications from a network entity, the activation message including one or more transmission parameters indicating at least a duration for transmissions on an uplink communication channel and an uplink sTTI pattern for the transmissions on the uplink communication channel.
