BUFFER STATUS REPORTING AND LOGICAL CHANNEL PRIORITIZATION IN MULTIFLOW OPERATION

摘要

Uplink reporting and logical channel prioritization in multiflow operation is described. In some embodiments, uplink reporting for multiflow operation utilizes bearer level splitting where the UE associates bearers or logical channel groups (LCGs) with cells for uplink reporting. In some embodiments, uplink reporting for multiflow operation utilizes packet level splitting where the UE groups buffers for all LCGs into a common pool for uplink reporting. In packet level splitting embodiments, the UE may perform uplink reporting based on the total amount of data available for transmission in the common buffer pool or by applying scaling coefficients associated with the serving cells. Some embodiments manage mapping of logical channel payloads to uplink grants for multiflow operation.

1. A method of wireless communication by a user equipment (UE) in communication with a first cell and a second cell, comprising:
establishing a first component carrier at the UE associated with the first cell; establishing a second component carrier at the UE associated with the second cell while maintaining the first component carrier; determining a set of logical channel groups having available data for uplink transmission from the UE; transmitting a first uplink report to the first cell, the first uplink report based at least in part on the available data; and transmitting a second uplink report to the second cell, the second uplink report based at least in part on the available data.
