PDSCH ASSIGNMENT INDICATION FOR FDD SCELL ACK/NACK TRANSMISSION

摘要

A pico network node sends to a UE an allocation of physical downlink shared channel PDSCH subframes on the SCell. The allocation has control signaling indicating a number of the allocated PDSCH subframes that lie within a multiplexing window. The pico network node sends to the UE data on each of the allocated downlink subframes. The UE is also configured for a PCell with a macro network node not co-located with the pico. The UE determines from control signaling the number of PDSCH subframes that are allocated; and checks the determined number against PDSCH subframes it's received, to detect whether any allocated PDSCH subframe is missed. In an embodiment the control signaling is two bits per allocated downlink subframe as an assignment indication.

主权项

1. An apparatus comprising:
at least one processor; and at least one memory including computer program code,
in which the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus at least to: determine from control signaling a number of physical downlink shared channel PDSCH subframes within a multiplexing window that are allocated for a user equipment; and check the determined number against PDSCH subframes received within the multiplexing window to detect whether or not any allocated PDSCH subframe within the multiplexing window is missed;wherein the control signaling and the corresponding PDSCH subframe are received on a secondary cell SCell from a pico network node and the user equipment is also configured for a primary cell PCell with a macro network node not co-located with the pico network node.
