Abstract
Methods, systems, and devices for determining priority of transport channels and transmission signals. Some embodiments can be used in wireless communication embodiments in which multiple uplink transport channels or transmission signals need to be concurrent transmitted, such as in dual-connectivity mode, where the determined priority can be used to preferentially allocate uplink transmit power to higher priority transport channels and transmission signals.
Claims19
A method of wireless communication, comprising:
- determining, by a wireless device in a dual-connectivity mode including two or more links with two or more cell groups of a same communication technology, a priority of each transmission element of a plurality of transmission elements, wherein the plurality of transmission elements comprises one or more of a transport channel or a transmission signal, wherein a respective priority of each transmission element is based on a corresponding transmission type of the respective transmission element, and wherein at least one of the transmission types is assigned to a first transport channel and a first transmission signal;
- determining, by the wireless device, a total power allocated in the dual-connectivity mode, for scheduled concurrent uplink grants within a time overlap;
- and
- allocating, by the wireless device, transmission power of the total power, to respective transmission elements of the plurality of transmission elements for transmission via respective links of the respective cell groups, based on the priority of each transmission element, for the time overlap.
1 more element
A wireless communication apparatus in a dual-connectivity mode, comprising:
- at least one processor configured to:
- maintain, in the dual-connectivity mode, two or more links with two or more cell groups of a same communication technology;
- determine a priority of each transmission element of a plurality of transmission elements, wherein the plurality of transmission elements comprises one or more of a transport channel or a transmission signal, wherein a respective priority of each transmission element is based on a corresponding transmission type of the respective transmission element, and wherein at least one of the transmission types is assigned to a first transport channel and a first transmission signal;
- determine a total power allocated in the dual-connectivity mode, for scheduled concurrent uplink grants within a time overlap;
- and
- allocate transmission power of the total power, to respective transmission elements of the plurality of transmission elements for transmission via respective links of the respective cell groups, based on the priority of each transmission element, for the time overlap.
