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). ## Claims ### Claim 1 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. ### Claim 2 (depends on 1) The method of claim 1, further comprising: identifying one or more link properties associated with the first time division multiple access link, the second time division multiple access link, or both, wherein the coordinated transmission schedule is identified based at least in part on the one or more link properties. ### Claim 3 (depends on 2) The method of claim 2, wherein the one or more link properties comprise a synchronous link property, an asynchronous link property, an isochronous link property, a quality of service requirement, or some combination thereof, associated with the first time division multiple access link, or the second time division multiple access, or both. ### Claim 4 (depends on 1) The method of claim 1, further comprising: monitoring a network neighborhood channel, wherein the scheduling information is received based at least in part on the monitoring. ### Claim 5 (depends on 4) The method of claim 4, further comprising: advertising the scheduling information for the first time division multiple access link, scheduling information for the second time division multiple access link, the coordinated transmission schedule, or some combination thereof, during an entry of the network neighborhood channel. ### Claim 6 (depends on 1) The method of claim 1, wherein: receiving the scheduling information comprises receiving the scheduling information from the second wireless device. ### Claim 7 (depends on 1) The method of claim 1, further comprising: identifying one or more communication periods associated with the first time division multiple access link, the second time division multiple access link, or both; and identifying a scheduling conflict based at least in part on the one or more communication periods, wherein the coordinated transmission schedule is identified based at least in part on the identified scheduling conflict. ### Claim 8 (depends on 1) The method of claim 1, further comprising: transmitting the scheduling information for the first time division multiple access link, scheduling information for the second time division multiple access link, the coordinated transmission schedule, or some combination thereof, to a fourth wireless device. ### Claim 9 (depends on 1) The method of claim 1, wherein the another wireless device comprises the second wireless device. ### Claim 10 (depends on 1) The method of claim 1, wherein the another wireless device comprises a fourth wireless device. ### Claim 11 (depends on 1) The method of claim 1, further comprising: identifying clock information associated with the second wireless device and the third wireless device;
