US 10,772,112 B2 · Network neighborhood alignment

Abstract

Generally, the described techniques provide for transmission schedule coordination, and in some cases transmission schedule modification, for time division multiple access (TDMA) links amongst devices engaged in communications. A network neighborhood alignment (NNA) protocol may allow devices to inform peer devices of current (e.g., established) connections within the network neighborhood (e.g., of TDMA links established between the device and peer devices, or of TDMA links established between other per devices that are known to the device). Devices may also communicate desired connection preferences, requests for peer device current connection information (e.g., the types of data being transferred by a peer device, the connection type of links associated with the peer device), etc. In some examples, the NNA protocol may establish the information exchange via a dedicated network neighborhood channel (NNC) or via point-to-point messages exchanged between devices (e.g., where the information may then be relayed amongst peer devices).

Dependent claims

A method for wireless communication at a first wireless device, comprising:

receiving scheduling information for a first time division multiple access link between a second wireless device and a third wireless device;
identifying, based at least in part on the scheduling information for the first time division multiple access link, a coordinated transmission schedule that comprises transmission scheduling information for the first time division multiple access link and a second time division multiple access link between the first wireless device and another wireless device;
establishing a third time division multiple access link between the first wireless device and a fourth wireless device based at least in part on the coordinated transmission schedule, wherein the coordinated transmission schedule is identified based at least in part on a connection preference for the third time division multiple access link;
and
modifying the second time division multiple access link between the first wireless device and the another wireless device based at least in part on the coordinated transmission schedule.
