Problems solved by technology

[0007] Some prioritization and power scaling mechanisms have been specified for intra-eNB CA, however, even if there is coordination between schedulers, these mechanisms only contain minimal coordination, and control plane data is only transmitted with a single Uu interface

Embodiment approach

[1026]If the processing time budget is sufficient, the WTRU may determine to allocate power by predicting, otherwise it may allocate power using guaranteed power. For example, upon determining that the processing time reduction is below a certain threshold, the WTRU may determine that it should perform power allocation according to a first method, otherwise perform power allocation according to a second method. As an example, the first method may be based on determining the power allocated to each CG by considering the power required by each CG, while the second method may be based on the power allocated to each CG, wherein the Allocation is based on the power required to transmit the earliest starting CG and the guaranteed amount of power for other CGs.

[1027] For the first approach, as an example, the WTUR may perform power allocation and / or power scaling according to the methods described herein and per CG (eg, CG-by-CG allocation) or on all transmissions of the WTRU (eg,...

Embodiment

[1108] CLAIMS 1. A method for allocating uplink transmission power of a wireless transmit / receive unit (WTRU) during a time interval, the method comprising:

[1109] configuring the WTRU with a first minimum guaranteed power for a first uplink transmission from the WTRU using uplink from at least one cell in a first cell group (CG) link resources; and

[1110] configuring the WTRU with a second minimum guaranteed power for a second uplink transmission from the WTRU using uplink resources of at least one cell in a second CG;

[1111] wherein each of the first minimum guaranteed power and the second minimum guaranteed power is a ratio of total power (Pcmax) available to the WTRU for uplink transmission during the time interval; and

[1112] The remaining power is equal to Pcmax minus the sum of the first minimum guaranteed power and the second minimum guaranteed power.

[1113] 2. The method as described in embodiment 1, further comprising:

[1114] the WTRU allocates a first...

Abstract

Methods and devices for offloading and / or aggregation of resources to coordinate uplink transmissions when interacting with different schedulers are disclosed herein. A method in a WTRU includes functionality for coordinating with a different scheduler for each eNB associated with the WTRU's configuration. Disclosed methods include autonomous WTRU grant selection and power scaling, and dynamic prioritization of transmission and power scaling priority.
