Claim Rejections - 35 USC § 102
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale or otherwise available to the public before the effective filing date of the claimed invention.
Claims 1-30 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Li et al. (US Pub. 20160080052 A1).
For claims 1 and 17, Li discloses a user equipment (UE) (UEO) for wireless communication, comprising:
one or more memories; and one or more processors coupled to the one or more memories (Fig. 1A, [0092], "As shown in further detail in FIG. 1A, each system 120 for the UE (UEO) depicted in FIG. 1 and other, similar UEs (not shown) ... include: a processor 121, a memory 122, a transceiver 123 including a transmitter and a receiver, and an antenna array 124."), the one or more processors individually or collectively configured to (Fig. 20; [0202], "The overall procedure is illustrated in FIG. 20, wherein the pattern is termed the "array geometry pattern," or "antenna subsampling/ downsampling pattern," or "CSI-RS subsampling/downsampling pattern"; [0196-201]):
receive a reduced antenna port indication for spatial element adaptation associated with at least one reduced channel state information reference signal (CSI-RS) antenna port configuration (Fig. 20, item 2002; [0202], "The procedure 2000 begins with an eNB signalling one or more array subsampling or geometry pattern(s) to UE(s) served by the eNB (step 2001).
Each UE receives the one or more array geometry pattern(s) (step 2002). "; Fig. 6A, [0110], "In some embodiments, in order to maintain small CSI-RS overhead, the eNB transmits CSI-RS only on a subset of antennas as illustrated in FIG. 6A (hence the term "antenna subsampling" or "antenna array subsampling")."; [0093], "With such antennas, the eNB can form beams in both horizontal and vertical domain, fully exploiting the spatial diversity, and is capable to support high-order MU-MIMO. To steer beams towards User Equipments (UEs), the eNB must acquire channel state information (CSI) of the UEs, which is typically obtained by downlink training (e.g., via CSI reference signal, or "CSI-RS") and uplink feedback of precoding matrix indicator (PMI) information and channel quality indicator (CQI) information in frequency division duplex (FDD) systems.");
receive at least one CSI-RS based on the at least one reduced CSI-RS antenna port configuration (Fig. 20, item 2003, [0202], "The eNB then eNB transmits CSI-RS according to patterns (step 2003)."); and
compute channel state information (CSI) based on the at least one CSI- RS (Fig. 20, item 2004; [0202], "The UE constructs a feedback report for associated array pattern(s) based on the received CSI-RSs (step 2004).").
Claim 17 differs from claim 1 only by the additional recitation of the following limitation, which is also taught by the cited prior art. The cited prior art further discloses a method of wireless communication performed by a user equipment (UE) (Fig. 20).
All other identical limitations are rejected based on the same rationale as shown above.
For claims 9 and 25, Li discloses a network node (101) for wireless communication, comprising: one or more memories (Fig. 1A, [0092], "As shown in further detail in FIG. 1A, each system 120 for the eNB depicted in FIG. 1... include: a processor 121, a memory 122, a transceiver 123 including a transmitter and a receiver, and an antenna array 124."); and
one or more processors coupled to the one or more memories, the one or more processors individually or collectively configured to (Fig. 20; [0202], "The overall procedure is illustrated in FIG. 20, wherein the pattern is termed the "array geometry pattern," or "antenna subsampling/ downsampling pattern," or "CSI-RS subsampling/downsampling pattern"; [0196-201]):
transmit a reduced antenna port indication for spatial element adaptation associated with at least one reduced channel state information reference signal (CSI-RS) antenna port configuration (Fig. 20, item 2001; [0202], "The procedure 2000 begins with an eNB signalling one or more array subsampling or geometry pattern(s) to UE(s) served by the eNB (step 2001).
Each UE receives the one or more array geometry pattern(s) (step 2002). "; Fig. 6A, [0110], "In some embodiments, in order to maintain small CSI-RS overhead, the eNB transmits CSI-RS only on a subset of antennas as illustrated in FIG. 6A (hence the term "antenna subsampling" or "antenna array subsampling")."; [0093], "With such antennas, the eNB can form beams in both horizontal and vertical domain, fully exploiting the spatial diversity, and is capable to support high-order MU-MIMO.

transmit at least one CSI-RS based on the at least one reduced CSI-RS antenna port configuration (Fig. 20, item 2003; [0202], "The UE constructs a feedback report for associated array pattern(s) based on the received CSI-RSs (step 2003).").
Claim 25 differs from claim 9 only by the additional recitation of the following limitation, which is also taught by the cited prior art. The cited prior art further discloses a method of wireless communication performed by a network node (Fig. 20).
All other identical limitations are rejected based on the same rationale as shown above.
For claims 2, 10, 18, and 26, Li discloses the reduced antenna port indication comprises a bitmap indicating, for each antenna port of a plurality of antenna ports of the UE, whether the antenna port is to be used for deriving a CSI-RS resource ([0243] that "a subsampling pattern is indicated by an antenna port bitmap, wherein i-th bit indicates whether the i-th antenna port carries non-zero power CSI-RS or zero-power CSI-RS").

Each UE receives the one or more array geometry pattern(s) (step 2002).
