Embodiment Construction

[0046] User Equipment (UE) and / or base stations within a wireless system operating in a shared or unlicensed radio spectrum band (eg, MulteFire or other self-contained shared spectrum systems) may initiate channel clearing procedures between the UE and the base station to obtain the medium and reduce potential conflicts. In such scenarios, the UE and / or base station may perform a clear channel assessment (CCA) (such as a listen before talk (LBT) procedure) when attempting to access the medium. After a successful CCA procedure, the UE and / or base station may transmit a busy signal (eg, to reserve the channel) before initiating a channel clear signal, such as a request to send / clear to send (RTS / CTS) handshake. For example, the UE may transmit a channel clear signal (eg, RTS) after the busy signal, which may prompt the base station to respond with a corresponding second channel clear signal (eg, CTS). The UE may then begin transmissions (eg, physical uplink shared channel (PUSC...

Abstract

Methods, systems and devices for wireless communications are described. A user equipment (UE) may receive an uplink grant conveying an indication of a multiple transmission opportunity (TxOP) grant. During the first TxOP, the UE may transmit a first uplink transmission in one or more subframes according to the multiple TxOP grant. During the second TxOP, the UE may transmit a second uplink transmission in one or more subframes according to the multiple TxOP grant.

Description

[0001] cross reference [0002] This patent application claims U.S. Provisional Patent Application No. 62 / 454,798, filed February 4, 2017 by Yerramalli et al., entitled "PhysicalUplink Shared Channel Coverage Enhancements," and by LASTNAME Priority to U.S. Patent Application No. 15 / 880,507, filed Jan. 25, 2018, and entitled "Physical Uplink Shared Channel Coverage Enhancements," each of which are assigned to the assignee of this application. technical field [0003] The following relates generally to wireless communications, and in particular to physical uplink shared channel coverage enhancement. Background technique [0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcast, and the like. These systems may be able to support communication with multiple users by sharing available system resources (eg, time, frequency, and power). Examples of such multiple-access sy...
