摘要
Techniques, apparatus and methods are disclosed that enable non-adaptive Hybrid Automatic Repeat Request (HARQ) retransmission using SPS resources. Non-adaptive HARQ retransmission can be enabled in a configured Uplink (UL) resource (such as SPS resources). As it may not be beneficial to allow non-adaptive HARQ retransmission on SPS resources for all kinds of traffic, options for proper configuration can be provided either by network signaling or by predefined configurations. For example, embodiments are described to enable non-adaptive retransmission using SPS resources: Always allow non-adaptive retransmission on configured UL grants; Allow non-adaptive retransmission on configured UL grants only for certain predefined conditions; Allow non-adaptive HARQ retransmissions when there is no data in the UL buffer for new transmission; Enable non-adaptive retransmissions using a configurable boolean parameter; Enable non-adaptive retransmissions using a configurable threshold parameter; and Enable non-adaptive retransmissions using a configuration sent using a system information broadcast.
