Description

Cross-reference This patent application claims the interests of U.S. Provisional Patent Application No. 62/873,836, filed July 12, 2019, entitled “Preconfigured Uplink Resource Techniques in Wireless Communications,” and U.S. Patent Application No. 16/926,164, filed July 10, 2020, entitled “Preconfigured Uplink Resource Techniques in Wireless Communications,” each of which is assigned to the assignee of this application. The following concerns wireless communications in general, and more specifically, pre-configured uplink resource techniques in wireless communications. Wireless communication systems are widely deployed to provide various types of communication content, including voice, video, packet data, messaging, and broadcast. These systems may support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth-generation (4G) systems such as Long-Term Evolution (LTE) systems, LTE-A systems, or LTE-A Pro systems, and fifth-generation (5G) systems, sometimes referred to as New Radio (NR) systems. These systems may employ technologies such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), or Discrete Fourier Transform Spread Orthogonal Frequency Division Multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include several base stations or network access nodes, each simultaneously supporting communication for multiple communication devices, which may sometimes be referred to as user equipment (UEs). In some cases, a UE may have only a relatively small amount of data to be transmitted periodically. For example, a UE may be associated with a sensor that periodically provides readings to network nodes. In some cases, to obtain uplink resources for uplink transmission, a UE may send a request for uplink data resources (for example, a buffer status report (BSR) indicating that the UE has data to transmit may be provided to the base station), receive uplink permission in response to the request, and then transmit uplink data in accordance with the uplink permission. When a UE has only a relatively small amount of data to transmit, such a procedure consumes a significant amount of overhead compared to the amount of data being transmitted. Efficient techniques for allocating uplink resources to UEs for "grant-free" uplink transmissions (i.e., not requiring multi-step communication just to obtain uplink permission each time) can enable more efficient network operation through such uplink resource allocation and reduced overhead associated with such uplink transmissions.
