Abstract:
The disclosure provides for rate adaptation based on channel power tracking in wireless communications. An Access Point (AP) may measure a full-band channel quality information (CQI) for a plurality of wireless stations associated with the AP and allocate a sub-band resource unit from the plurality of sub-band resource units to a wireless station based on the full-band CQI. Aspects of the disclosure also include techniques for adjusting a data rate associated with the wireless station based on a channel power of the sub-band resource unit.
Abstract:
A base station that implements an improved link adaptation process that takes into account the fact that a certain reference signal (e.g., CSI-RS) may be seen as interference by certain wireless communication devices (WCDs). Accordingly, when the base station schedules a data transmission for the WCD to occur in a particular ΤΉ and the base station is scheduled to transmit the CSI-RS during the same TTI, the base station will tend to select a more robust MCS for the data transmission to the WCD to counter effect the possible interference caused by the CSI-RS.
Abstract translation:实现改进的链路自适应过程的基站,其考虑到某些参考信号(例如,CSI-RS)可被视为某些无线通信设备(WCD)的干扰的事实。 因此,当基站调度在特定的T H H发生的WCD的数据传输,并且基站被调度为在相同的TTI期间发送CSI-RS时,基站将倾向于为数据选择更稳健的MCS 传输到WCD以对抗CSI-RS引起的可能干扰。
Abstract:
An objective of the present invention is to provide a method and apparatus for reporting CSI for superposition transmission. A first UE reports, based on a first BLER indicated by a corresponding base station, a first CSI corresponding to the first BLER to the base station; reports, based on at least one second BLER indicated by the base station, at least one second CSI corresponding to the at least one second BLER, to the base station, wherein the base station performs superposition transmission with the first UE and at least one second UE paired therewith, wherein a value of the at least one second BLER is different from a value of the first BLER. Compared with the prior art, the present invention does not require the UE to perform interference cancellation/ suppression during a CQI measurement period for the second CSI. Therefore, the present invention does not have the complication as found in the Post-NAICS CQI. The present invention designs some restrictions and/or changes some existing standards when generating a CSI report, such that the report is more useful and more beneficial to the superposition transmission schemes, which enhances system efficiency and promotes user experience.

Techniques are described for wireless communication. A first method includes determining, at a user equipment (UE), that the UE is exposed to a bursty interference in a shared radio frequency spectrum band, and modifying, based at least in part on the bursty interference, a feedback message reporting by the UE to a base station. A second method includes determining, at a base station, that a UE is exposed to a bursty interference in a shared radio frequency spectrum band, and modifying, based at least in part on the bursty interference, one or more of: a link adaptation for the UE or a transmission schedule for the UE.
