wherein the first OCC corresponds to each frequency domain unit in a first CDM group of the different CDM groups (LI, see Para’s [0010] i.e., an RS sequence of each antenna port is generated, then each element of each RS sequence is spread to obtain an spread RS sequence, where an spreading code may be a Walsh code, and RE mapping (i.e., “each frequency domain unit”) is performed for the spread RS sequence, [0041], [0046-0047], & [0054] i.e., two different scrambling codes can be used for RS sequences corresponding to antenna ports respectively belonging to two different CDM RE groups) or one of two adjacent frequency domain units in a second CDM group of the different CDM groups,
and wherein the second OCC corresponds to each frequency domain unit in the second CDM group (LI, see Para’s [0010] i.e., an RS sequence of each antenna port is generated, then each element of each RS sequence is spread to obtain an spread RS sequence, where an spreading code may be a Walsh code, and RE mapping (i.e., “each frequency domain unit”) is performed for the spread RS sequence, [0041], [0046-0047], & [0054] i.e., two different scrambling codes can be used for RS sequences corresponding to antenna ports respectively belonging to two different CDM RE groups) or each frequency domain unit in the second CDM group other than the one of the two adjacent frequency domain units in the second CDM group corresponding to the first OCC.
Li in view of Xiong does not disclose the claim features of the first OCC represented by a and the second OCC represented by -a, where a is a matrix. However the claim features would be rendered obvious in view of Davydov et al. US (2018/0091277).
Davydov discloses a first OCC represented by a and a second OCC represented by -a (see Para’s [0049] i.e., pairs of subsequent antenna ports are multiplexed with OCCs {1,1} (i.e., “a”) and {1,-1} (i.e.,”-a”)),
where a is a matrix (see Para [0049] i.e. {1,1}, {1, -1})
(Davydov suggests the pair of OCCs are used to multiplex a pair of antenna ports can be varied to provide randomized interference from adjacent subcarriers resulting in improving performance for larger number of CSI-RS signals (see Para’s [0044] & [0049])).
Therefore it would have been obvious to one of ordinary skill in the art before the effective filing date for the first OCC and the second OCC as disclosed in Li in view of Xiong to each be represented by a and -a according to the pair of OCCs disclosed in Davydov who discloses a first OCC represented by a and a second OCC represented by -a, because the motivation lies in Davydov that the pair of OCCs are used to multiplex a pair of antenna ports can be varied to provide randomized interference from adjacent subcarriers resulting in improving performance for larger number of CSI-RS signals.
Allowable Subject Matter
Claims 7, 14, 21, and 29 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
