As per claim 1, Soriaga discloses a method of scheduling wireless communications based on channel estimate aging [fig. 1, paragraphs 0011, 0049, 0060, a method of scheduling wireless communications based on channel estimate aging (wireless communications channels between UEs 102 and wireless base stations 104, enhance the efficiency of use of available bandwidth in wireless communications channels between one or more UEs 102 and one or more base stations 104)], the method comprising:
generating channel estimates based on signals wirelessly transmitted by user equipments [fig. 10, 14, paragraphs 0004, 0011, 0050, 0051, 0066, 0084, 0085, 0089, 0102, 0105, generating channel estimates based on signals wirelessly transmitted by user equipments (the UE or base station may determine that channel conditions are poor; the base station 104 determines whether the channel conditions between the base station 104 and a UE 102 are poor)];
determining aging metrics associated with the channel estimates [paragraphs 0005, 0051, 0066, 0069, 0071, 0089, 0102, 0105, 0118, determining aging metrics associated with the channel estimates (maintain the channel at an acceptable quality level; use information (such as a multipath delay profile) from one channel; use the processing gain information to determine a minimum length of SRS necessary, and transmit a request for the minimum length SRS to the UE 102)]; and
scheduling wireless communications with at least some of the user equipments based on the aging metrics [paragraphs 0004, 0050, 0051, 0065, 0066, 0112, scheduling wireless communications with at least some of the user equipments based on the aging metrics (base station 104 may schedule transmissions with multiple UEs 102 to allow them the time needed to complete communications at the minimum PG; each UE may use a sounding reference signal (SRS) to aid in scheduling (e.g., determining which frequency bands are good or bad for data))].
Soriaga does not explicitly disclose wherein the aging metrics comprising a first aging metric for a first channel and a second aging metric for a second channel; such that a first wireless data transmission over the first channel is prioritized over a second wireless data transmission over the second channel when the first aging metric indicates lower channel uncertainty than the second aging metric.
However, Bertrand teaches the metrics comprising a first metric for a first channel and a second metric for a second channel [fig. 11A, 45A, table 2, 4, paragraphs 0008, 0083, 0089, 0092, 0106, 0117, 0126, 0130, 0136, the metrics comprising a first metric for a first channel and a second metric for a second channel (the UE's channel estimates and derive the relevant scheduling metric; the noise variance estimation performance for both TU and PA channels when varying the number of SRS users at 20 PRB SRS bandwidth)]; such that a first wireless data transmission over the first channel is prioritized over a second wireless data transmission over the second channel when the first metric indicates lower channel uncertainty than the second metric [fig. 11A, 45A, table 2, 4, paragraphs 0008, 0083, 0089, 0092, 0102, 0106, 0117, 0126, 0130, 0136, a first wireless data transmission over the first channel is prioritized over a second wireless data transmission over the second channel when the first metric indicates lower channel uncertainty than the second metric (better channel estimation performance with PA channel compared to TU channel is due to the slower channel variations in frequency domain; timing uncertainty for different channels; better channel estimation performance with PA channel compared to TU channel)].
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to improve upon the method described in Soriaga by including the metrics comprising a first metric for a first channel and a second metric for a second channel as taught by Bertrand because it would provide the Soriaga's method with the enhanced capability of efficiently providing better channel estimation [Bertrand, paragraph 0089, 0095].
The modified Soriaga does not explicitly disclose determining aging metrics associated with the channel estimates based on ages of the channel estimates, and wherein aging metric is associated with a more recent channel estimate.
However, Kushalnagar teaches determining aging metrics associated with the channel estimates based on ages of the channel estimates, and wherein aging metric is associated with a more recent channel estimate [fig. 2, claim 7, paragraphs 0009, 0018, 0022, 0025, 0027, 0041, determining aging metrics associated with the channel estimates based on ages of the channel estimates, and wherein aging metric is associated with a more recent channel estimate (channel information may be weighted by their age; more recent interference information may be weighted more heavily than less recent interference information in the process of selecting a channel)].
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to improve upon the modified method described in Soriaga by including w the aging metrics comprising aging metrics for the different channels as taught by Kushalnagar because it would provide the Soriaga's the modified method with the enhanced capability of mitigating interference problem in growing networks [Kushalnagar, paragraph 0002].

As per claim 3, Soriaga discloses the method of Claim 2,
wherein a first sounding reference signal of the sounding reference signals is wirelessly transmitted by a first user equipment of the user equipments in a first time slot, and a second sounding reference signal of the sounding reference signals is wirelessly transmitted by a second user equipment of the user equipments in a second time slot, the second time slot following the first time slot [fig. 5, 6, paragraphs 0063, 0067-0070, 0099, wherein a first sounding reference signal of the sounding reference signals is wirelessly transmitted by a first user equipment of the user equipments in a first time slot, and a second sounding reference signal of the sounding reference signals is wirelessly transmitted by a second user equipment of the user equipments in a second time slot, the second time slot following the first time slot (two UEs 102 scheduled to communicate during one SF 500; scheduled to communicate with the first and second UEs 102, the base station 104 allocates a first UL portion of the SF 500 to an SRS from the first UE 102 (e.g., SRS 1) and a second UL portion of the SF 500 to an SRS from the second UE 102 (e.g., SRS 2); communications between UE 102 and base station 104 can be divided in the time domain into subframes (SFs) 300)].
As per claim 4, Soriaga discloses the method of Claim 1, wherein the wireless communications are multiple-input multiple-output (MIMO) wireless communications [fig. 2, 4, paragraphs 0002, 0049, 0081, wherein the wireless communications are multiple-input multiple-output (MIMO) wireless communications (enhance the efficiency of use of available bandwidth in wireless communications channels between UEs 102 and wireless base stations 104, include more antennas (e.g., 16, 32, etc.) in MIMO arrays)].

It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to improve upon the method described in Soriaga by including wherein the wireless communications are time division duplexing as taught by Bertrand because it would provide the Soriaga's method with the enhanced capability of efficiently providing evaluation of the performance [Bertrand, paragraph 0008, 0083].
