A method for a wireless device operating in a wireless communication system includes receiving configuration information for configuring a non-Physical Uplink Control Channel (PUCCH) cell; and transmitting a Hybrid Automatic Repeat request (HARQ) feedback of the non-PUCCH cell on a special cell (SpCell) or a PUCCH cell other than SpCell, according to indication information. Further, when the indication information is not received with the configuration information, the HARQ feedback is transmitted on the SpCell, and when the indication information is received with the configuration information, the HARQ feedback is transmitted on the PUCCH cell.

Various embodiments disclosed herein provide for facilitating updating of slot format used for establishing the new radio sidelink. According an embodiment, a system can receiving a slot format over a sidelink, wherein the slot format comprises a first release parameter and a transmit period. The system can further facilitate determining whether the first release parameter matches a second release parameter stored in the memory. The system can further facilitate, in response to the determining indicating that the first release parameter matched the second release parameter, updating a resource map used to transmit data, resulting in an updated resource map. The system can further facilitate transmitting the slot format based on the transmit period.

Methods of optimizing transmission of data from a client to a remote data center are disclosed, as well as systems and computer program products related to the same. An exemplary method comprises: receiving data, at a first intervening data center, transmitted from a client and addressed to a terminal data center, wherein the first intervening data center and the terminal data center are selected from a plurality of connected data centers; and transferring the data, from the first intervening data center through one or more additional intervening data centers selected from the plurality of connected data centers, until the data reaches the terminal data center; wherein each data center in the plurality of data centers independently selects a connected data center to transfer the data to based upon the amount of latency and/or bandwidth available at the connected data center.
