The head wearable display can initiate, at a first time instance, a first downlink transmission to the console. The head wearable display can dynamically indicate, to the console, an end of the first downlink transmission, at a second time instance when transfer of data of the first downlink transmission is complete. The head wearable display can dynamically cause, relative to the second time instance, the console to begin an uplink transmission. The head wearable display can receive an indication to dynamically start a second downlink transmission, at a third time instance when transfer of data of the uplink transmission is complete. ## Claims ### Claim 1 A method comprising: initiating, by a head wearable display at a first time instance, a first downlink transmission to a console; dynamically indicating, by the head wearable display to the console, an end of the first downlink transmission, at a second time instance when transfer of data of the first downlink transmission is complete; dynamically causing, by the head wearable display, relative to the second time instance, the console to begin an uplink transmission; and receiving, by the head wearable display, an indication to dynamically start a second downlink transmission, at a third time instance when transfer of data of the uplink transmission is complete. ### Claim 2 (depends on 1) The method of claim 1, further comprising: estimating an expected duration for a data transmission interval between the head wearable display and the console according to an amount of data to be transferred and properties of a channel between the head wearable display and the console, the data transmission interval including the first downlink transmission and the uplink transmission. ### Claim 3 (depends on 1) The method of claim 1, further comprising: estimating, by the head wearable display, a time period for the first downlink transmission. ### Claim 4 (depends on 3) The method of claim 3, further comprising: determining, by the head wearable display, that there is additional data to transmit for the first downlink transmission; and responsive to the determination, continuing, by the head wearable display, to transfer data to the console beyond the estimated time period for the first downlink transmission. ### Claim 5 (depends on 1) The method of claim 1, further comprising: estimating, by the console, a time period for the uplink transmission. ### Claim 6 (depends on 5) The method of claim 5, further comprising: determining, by the console, that there is additional data to transmit for the uplink transmission; and responsive to the determination, continuing, by the console, to transfer data to the head wearable display beyond the estimated time period for the uplink transmission. ### Claim 7 (depends on 1) The method of claim 1, further comprising: dynamically supporting, by the head wearable display at a fourth time instance, addition of one or more link pairs for a data transmission interval between the head wearable display and the console according to data available at the fourth time instance, each link pair including at least one downlink transmission and at least one uplink transmission. ### Claim 8 (depends on 1) The method of claim 1, wherein a first wake up time period includes the first downlink transmission, the uplink transmission and the second downlink transmission, and the method further comprises dynamically determining, by the console, to add a second wake up time period to support additional one or more downlink transmissions and one or more uplink transmissions. ### Claim 9 (depends on 8) The method of claim 8, further comprising: dynamically configuring a duration of a sleep time period between the first wake up time period and the second wake up time period. ### Claim 10 A head wearable display comprising: one or more processors configured to: initiate, at a first time instance, a first downlink transmission to a console;
