Supplemental node transmission assistance in a wireless network
First Claim
1. A method of wireless communications between a wireless communications network and a wireless user equipment, comprising:
- identifying, by the wireless communications network, a first node of the wireless communications network as a serving node for the wireless user equipment, the serving node supporting transmissions in a first direction between the wireless user equipment and the wireless communications network;
identifying, by the wireless communications network, a second node of the wireless communications network as a supplemental node;
using, by the wireless communications network, the supplemental node for transmissions in a second direction between the wireless communications network and the wireless user equipment, wherein transmissions in the first direction are downlink transmissions from the serving node to the wireless user equipment, and transmissions in the second direction are uplink transmissions from the wireless user equipment to the supplemental node; and
wherein the serving node is responsible for determining a data rate or a transmission power for the transmissions in the second direction, the determining comprises;
determining retransmission statistics for transmissions in the second direction, wherein determining the retransmission statistics comprises determining an average number of hybrid automatic repeat request transmissions for uplink transmissions using a sliding window; and
adapting the data rate or the transmission power for the transmissions in the second direction based on the determined retransmission statistics.

Abstract
Supplemental node transmission assistance in a wireless network provides for transmissions between a wireless network and wireless user equipment in a first direction using a serving node of the wireless network while providing for transmissions between the wireless network and wireless user equipment in a second direction using a supplemental node of the wireless network. The supplemental node is selected based on providing better channel conditions between the network and the user equipment in the second direction than the serving node. The supplemental node thus provides transmission assistance for the serving node in order to provide the best available downlink and uplink communications between the user equipment and the network.
