Abstract:
1. A method comprising: receiving at an access point a timing information frame from a first telecommunications station via a shared-communications channel in accordance with a first protocol, wherein the timing information frame comprises timing information, and wherein the timing information indicates a future transmit time of at least a first of a series of transmissions that the first telecommunications station will transmit into the shared-communications channel in accordance with a second protocol that is not understood by the access point; the access point refraining from transmitting to the first telecommunications station in accordance with the first protocol during each transmission of the series of transmissions indicated by the timing information; transmitting a data frame from the access point to the first telecommunications station via the shared-communications channel in accordance with the first protocol between the transmit times of consecutive packets in the series of packets by the first telecommunications station; and receiving, by the access point, updated timing information via the shared-communications channel in accordance with the first protocol, wherein the updated timing information is based at least in part on: (a) the data frame transmitted from the access point, and (b) the series of transmissions.
