Accommodating semi-persistent scheduling in heterogeneous networks with restricted subframe patterns

摘要

A method is provided for operating a network element in a wireless communications network. The method comprises transmitting, by a network element configured to utilize time domain measurement resource restriction, a first initial transmission under a semi-persistent scheduling (SPS) scheme, wherein retransmissions of the first initial transmission follow a first retransmission pattern. The method further comprises transmitting, by the network element, a second initial transmission under the SPS scheme, wherein retransmissions of the second initial transmission follow a second retransmission pattern, the second retransmission pattern allowing at least one retransmission of the second initial transmission to occur in a restricted subframe.

1. A method for operating a network element in a wireless communications network, the method comprising:
transmitting, by a network element configured to utilize time domain measurement resource restriction to mitigate interference, a first initial transmission under a semi-persistent scheduling (SPS) scheme, wherein retransmissions of the first initial transmission follow a first retransmission pattern that is aligned with a restricted subframe pattern; and transmitting, by the network element, a second initial transmission under the SPS scheme, wherein retransmissions of the second initial transmission follow a second retransmission pattern, the second retransmission pattern allowing at least one retransmission of the second initial transmission to occur in a restricted subframe, wherein retransmissions in the first retransmission pattern occur every fixed number of subframes and coincide with restricted subframes, and wherein the at least one retransmission of the second initial transmission occurs a predetermined number of subframes later than the second initial transmission, the predetermined number being different than the fixed number.
