Abstract
A technique may include receiving, by a user device in a wireless network, an indication of a set of uplink time-frequency resources to be used for an uplink transmission from the user device to both a master cell and a slave cell, determining, by the user device, a timing advance associated with the master cell, and performing a single transmission, by the user device, of a block of data to both of the master cell and the slave cell via the set of uplink time-frequency resources using the timing advance associated with the master cell.
Claims20
A method comprising:
- determining, by a slave cell, a set of buffer gap resources that are adjacent to a set of uplink resources to be used for an uplink transmission from a user device to both a master cell and the slave cell, the set of buffer gap resources being based on a difference between a first propagation delay between the user device and the master cell and a second propagation delay between the user device and the slave cell;
- and
- reserving, by the slave cell, both the set of uplink resources for uplink transmission and the adjacent set of buffer gap resources, to accommodate an uplink transmission from the user device based on a timing advance associated with the master cell.
A method comprising:
- receiving, by a user device in a wireless network, an indication of a set of uplink time-frequency resources to be used for an uplink transmission from the user device to both a master cell and a slave cell;
- determining, by the user device, a timing advance associated with the master cell;
- performing a single transmission, by the user device, of a block of data to both of the master cell and the slave cell via the set of uplink time-frequency resources using the timing advance associated with the master cell.
An apparatus comprising at least one processor and at least one memory including computer instructions, when executed by the at least one processor, cause the apparatus to:
- receive, by a user device in a wireless network, an indication of a set of uplink time-frequency resources to be used for an uplink transmission from the user device to both a master cell and a slave cell;
- determine, by the user device, a timing advance associated with the master cell;
- perform a single transmission, by the user device, of a block of data to both of the master cell and the slave cell via the set of uplink time-frequency resources using the timing advance associated with the master cell.
