Methods to determine maximum number of valid unicast DCI per span and monitoring occasion
A method and system are provided. The method includes receiving a number of physical downlink control channels (PDCCHs) for decoding, determining a maximum number of valid downlink control information (DCIs) that can be decoded, increasing a maximum number of PDCCHs that can be decoded based on the determined maximum number of valid DCIs, and decoding the number of PDCCHs.
1 . A method, comprising
receiving a number of physical downlink control channels (PDCCHs) for decoding;
determining a maximum number of valid downlink control information (DCIs) distributed in a plurality of monitoring occasions (MOs) included in a span that can be decoded as a function of a total number of the plurality of MOs included in the span, wherein the maximum number of valid DCIs that can be decoded is determined per MO as a function of subcarrier spacing (SCS) of a scheduling cell or as a function of span patterns supported by a user equipment (UE);
increasing a maximum number of PDCCHs that can be decoded based on the determined maximum number of valid DCIs; and
decoding the number of PDCCHs based on the increased maximum number of PDCCHs.
2 . The method of claim 1 , wherein the maximum number of valid DCIs that can be decoded per MO is configured by a network.
3 . The method of claim 1 , wherein the maximum number of valid DCIs that can be decoded per MO is determined as a function of subcarrier spacing (SCS) of a scheduling cell.
4 . The method of claim 1 , wherein the maximum number of valid DCIs that can be decoded per MO is determined as a function of span patterns supported by a user equipment (UE).
5 . The method of claim 1 , wherein the maximum number of valid DCIs that can be decoded per MO is determined based on a maximum number of valid DCIs that can be decoded per span and the total number of the plurality of MOs included in the span.
6 . The method of claim 1 , wherein determining the maximum number of valid DCIs that can be decoded comprises determining a maximum number of valid DCIs that can be decoded per span.
7 . The method of claim 6 , wherein the maximum number of valid DCIs that can be decoded per span is determined as a function of SCS of a scheduling cell.
8 . A system, comprising:
a memory; and
a processor configured to:
receive a number of physical downlink control channels (PDCCHs) for decoding;
determine a maximum number of valid downlink control information (DCIs) distributed in a plurality of monitoring occasions (MOs) included in a span that can be decoded as a function of a total number of the plurality of MOs included in the span, wherein the maximum number of valid DCIs that can be decoded is determined per MO as a function of subcarrier spacing (SCS) of a scheduling cell or as a function of span patterns supported by a user equipment (UE);
increase a maximum number of PDCCHs that can be decoded based on the determined maximum number of valid DCIs; and
decode the number of PDCCHs based on the increased maximum number of PDCCHs.
9 . The system of claim 8 , wherein the maximum number of valid DCIs that can be decoded per MO is configured by a network.
10 . The system of claim 8 , wherein the maximum number of valid DCIs that can be decoded per MO is determined as a function of subcarrier spacing (SCS) of a scheduling cell.
11 . The system of claim 8 , wherein the maximum number of valid DCIs that can be decoded per MO is determined as a function of span patterns supported by a user equipment (UE).
12 . The system of claim 8 , wherein the maximum number of valid DCIs that can be decoded per MO is determined based on a maximum number of valid DCIs that can be decoded per span and the total number of the plurality of MOs included in the span.
13 . The system of claim 8 , wherein the processor is configured to determine the maximum number of valid DCIs that can be decoded by determining a maximum number of valid DCIs that can be decoded per span.
14 . The system of claim 13 , wherein the maximum number of valid DCIs that can be decoded per span is determined as a function of SCS of a scheduling cell.
