one or more codepoints indicating the one or more subgroups;

one codepoint with 8 bits or 16 bits indicating one subgroup; and/or

In some embodiments, the codepoint could be an index, ID or a value. It is an indication state via the LP-WUS. For example, if the LP-WUS has 8 bits, ‘00000000’ or ‘11111111’ indicated via the LP-WUS is a codepoint.

In some embodiments, the LP-WUS may indicate one or more subgroups by the codepoint.

In some embodiments, the LP-WUS indicates one or more subgroups to perform said behavior (e.g., wake up) based on an indication state (also referred to as “state” in present disclosure) of the LP-WUS. In some embodiments, the indication state of the LP-WUS comprises a binary value, decimal value, a codepoint, an index, and/or a ID. Different states correspond to different indications or different subgroups. Some examples are provided below.

One subgroup indication:

In some embodiments, if the maximum number of subgroups per PO (or in at least one PO) is configured as 8, 8 states in the LP-WUS is needed for indicating the subgroup index. In some embodiments, if the maximum number of subgroups per PO (or in at least one PO) is configured as 16/32/64/128/256, the 16/32/64/128/256 states in the LP-WUS is needed for indicating the subgroup index.

In some embodiments, for configured 16 subgroups, the state may be one of: 0000, 0001, 0010, 0011, 0100, 0101, 0110, 0111, 1000, 1001, 1010, 1011, 1100, 1101, 1110, 1111.

In some embodiments, based on 3 bits indication states 000, 001, 010, 011, 100, 101, 110, 111, more states with N bits may be constructed. For example, when N=4 bits is used, based on 000, 001, 010, 011, 100, 101, 110, 111, it only needs to add ‘1’ or ‘0’ before the 8 indication states, then 16 indication states for 4bits can be obtained.
