Methods and systems for access point dis- /00 covery provide for formation of a cluster to support the distributed MI- MO communication. In one aspect, a method includes generating, by a first access point, a first message indicating the first access point has distributed MIMO capability and transmitting, by the first access point, 1105 the first message on a wireless network. The method further includes re- ceiving, by the first access point, a second message from a second access RECEIVE A DISCOVERY MESSAGE INDICATING DISTRIBUTED MIMO point, the second message identifying a cluster and determining, by the PARAMETERS FOR AN ACCESS POINT first access point, to participate in the identified cluster in response to the second message. 1110 DETERMINE WHETHER TO PARTICIPATE IN A CLUSTER WITH THE ACCESS POINT BASED ON THE DISCOVERY MESSAGE 1115 PARTICIPATE IN A DISTRIBUTED MIMO COMMUNICATION VIA THE CLUSTER FIG. 11 omit IIl °nolo ow (10) International Publication Number WO 2018/160296 Al [Continued on next page] WO 2018/160296 Al IMEDIMOM0101011M1E130H10011010MOIERVOIMIE UG, ZM, ZW), Eurasian (AM, AZ, BY, KG, KZ, RU, TJ, TM), European (AL, AT, BE, BG, CH, CY, CZ, DE, DK, EE, ES, FI, FR, GB, GR, HR, HU, IE, IS, IT, LT, LU, LV, MC, MK, MT, NL, NO, PL, PT, RO, RS, SE, SI, SK, SM, TR), OAPI (BF, BJ, CF, CG, CI, CM, GA, GN, GQ, GW, KM, ML, MR, NE, SN, TD, TG).
