APPARATUS OF USER EQUIPMENT (UE) CONFIGURABLE FOR CONNECTIVITY WITH MULTIPLE CELL GROUPS

摘要

Embodiments of user equipment (UE) and methods for enhanced discontinuous reception (DRX) operations for inter eNB carrier aggregation (CA) in an LTE network are generally described herein. In some embodiments, a UE is configured to be served by multiple serving cells. The first set of the serving cells may be associated with a first eNB and a second set of serving cells may be associated with a second eNB. In these embodiments, DRX operations may be performed independently in multiple serving cells belonging to the different eNBs. Other embodiments for enhanced DRX operations are also described.

1. A apparatus of user equipment (UE) configurable for connectivity with multiple cell groups, the apparatus comprising: memory; and processing circuitry, configured to:
decode radio-resource control (RRC) signaling from a first cell group associated with a first enhanced node B (eNB), the RRC signaling to configure the UE with a second cell group, the second cell group associated with a secondary eNB, the UE configured to utilize scheduled radio resources of both the first and second cell groups; decode a first medium-access control (MAC) configuration element received for the first cell group and a second MAC configuration element for the second cell group, the MAC configuration elements to configure the UE for independent discontinuous reception (DRX) operations and independent buffer status reporting operations for each cell group, wherein the first MAC configuration element includes DRX configuration information and buffer status report (BSR) configuration information for the first cell group, and wherein the second MAC configuration element includes DRX configuration information and BSR configuration information for the second cell group; perform buffer status reporting and DRX operations for the second cell group independently of buffer status reporting and DRX operations for the first cell group; configure first uplink data for transmission to the first eNB in accordance with scheduling information received for the first cell group; and configure second uplink data for transmission to the second eNB in accordance with scheduling information received for the second cell group.
