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

Abstract
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.

14. A network element in a wireless communications network, the network element comprising:
-
a processor configured such that the network element, configured to utilize time domain measurement resource restriction to mitigate interference, transmits 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, wherein the processor is further configured such that the network element transmits a second initial transmission under the SPS scheme, wherein retransmissions of the second initial transmission follow a second retransmission pattern, wherein the second retransmission pattern allows 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. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

27. A method for operating a user equipment (UE) in a wireless communications network, the method comprising:
-
receiving, by the UE, a first initial transmission under a semi-persistent scheduling (SPS) scheme, wherein retransmissions of the first initial transmission follow a first retransmission pattern; and receiving, by the UE, 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 during which an almost blank subframe (ABS) may be transmitted by an aggressor or neighbor cell to protect the restricted subframe from interference, 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.

28. A user equipment (UE) comprising:
-
a processor configured such that the UE receives a first initial transmission under a semi-persistent scheduling (SPS) scheme, wherein retransmissions of the first initial transmission follow a first retransmission pattern, wherein the processor is further configured such that the UE receives a second initial transmission under the SPS scheme, wherein retransmissions of the second initial transmission follow a second retransmission pattern, and wherein the second retransmission pattern allows at least one retransmission of the second initial transmission to occur in a restricted subframe during which an almost blank subframe (ABS) may be transmitted by an aggressor or neighbor cell to protect the restricted subframe from interference, 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.
