Problems solved by technology

A TA command with the first TA granularity and first TA command size may in some cases be sufficient to realign the transmission timing of the first BPL, but not enough to successfully realign the transmission timing of the second BPL

Embodiment Construction

[0084] In some examples of wireless communication systems, user equipment (UE) and base stations may communicate via uplink or downlink transmissions. A transmission may be sent, eg, from the UE to the base station, and some time may be spent between the transmission at the UE and the reception at the base station. This delay can be accounted for by the timing advance (TA) value. That is, the TA value can be applied to scheduling of uplink transmissions such that uplink transmissions are sent earlier to account for delays. Thus, a first UE in a wireless communication system may have a first delay and a first TA value may be applied, while a second UE in a different location within the same wireless communication system may have a second delay and may apply a second TA value. Applying the first TA value and the second TA value to the first UE and the second UE may result in transmissions from the first UE and the second UE being aligned upon arrival at the base station. The ...

Abstract

Methods, systems, and devices for wireless communications are described. In general, the described techniques provide for adjusting beam pair link (BPL) specific timing advance command parameters for use in wireless communication systems. In some cases, the base station may determine that transmission timing at the UE may be misaligned. A timing advance (TA) command may be sent for the BPL. The UE may utilize more than one BPL and may switch communications from the first BPL to the second BPL. The second BPL may have a different timing misalignment than the first BPL, and the TA commands sent by the base station may not be sufficient to correct the timing misalignment of the second BPL. The base station can adjust TA command parameters (eg, TA command size or TA command granularity) so that the timing misalignment of the second BPL can be corrected.

Description

[0001] cross reference [0002] This patent application claims the benefit of U.S. Provisional Patent Application Serial No. 62 / 607,729, entitled "BeamSpecific Timing Advance Command Parameters," filed by Islam et al. on Dec. 19, 2017; and Islam et al., filed Nov. 16, 2018 of U.S. Patent Application Serial No. 16 / 193,736, entitled "Beam Specific Timing Advance Command Parameters," filed today; each of which is assigned to the assignee of the present application. technical field [0003] The following relates generally to wireless communications, and more particularly to beam-specific timing advance command parameters. 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 are capable of supporting communication with multiple users by sharing available system resources (eg, time, frequency, and power). Examples of ...
