[0225] Some first embodiments: user pairing for non-orthogonal multiple access (NOMA)
[0226]A technique to improve performance is to use non-orthogonal multiple access in the spatial domain by exploiting the fact that some users have very good channels (e.g. high gain) and some users have bad Access (NOMA) program. The technique then exploits the logarithmic capacity of the channel by multiplexing these users.
[0227] To address the coherent block limited T problem described above, a method is provided for reusing the same pilot for different wireless devices (eg, first and second wireless devices 120, 130) in the same cell. The RNN 110 assigns the same pilot (e.g., a shared uplink pilot signal) to two different wireless devices (e.g., first and second wireless devices 120, 130), one of the wireless devices (e.g., the first wireless device device 120) has a small path loss, while another wireless device (eg, second wireless device 130) has a higher path loss. For example...

[0250] Some second embodiments: Shared / dedicated UL pilot assignment through multiplexed control signaling
[0251] As described above, embodiments may improve throughput for some scenarios. Thus, it can be selectively used for example for initial transmission, or selectively for a subset of wireless devices having less data to transmit, lower data rate requirements (e.g. first and / or second wireless devices 120, 130), and only for pairs of wireless devices (eg, first wireless device 120 and second wireless device 130) that are suitable for pairing as described above. This means that the method used to select wireless devices to deploy the proposed technology may be an important consideration.
[0252] In some embodiments, use of this technique is limited to situations where the number of wireless devices exceeds a threshold; for example, the number of wireless devices exceeds the number of orthogonal uplink pilots. In some embodiments, wireless devices are assigned shared U...

[0255] Some third embodiments: power command settings and encoding parameters
[0256] as referenced above Figure 9 As described, rate adaptation to wireless devices (e.g., first and second wireless devices 120, 130) using shared pilots (e.g., shared uplink pilot signals) can be achieved by Power setting commands and encoding settings are implemented. These commands can also be as described above and as above Figure 12 are appended and decoded as schematically shown.
[0257] When the word "comprising" or "comprises" is used, it should be construed non-limitingly, meaning "consisting of at least". Also, when the word "a" or "an" is used herein, it should be construed as "at least one", "one or more" and the like.
