Abstract: Embodiments provide systems and methods for adaptive reference signal mapping in wireless multi-access communication networks, including LTE, WLAN, WiMAX, Bluetooth, etc. In an embodiment, the reference signal mapping configuration is user equipment (UE) specific and can be configured semi-statically or dynamically according to one or more communication related parameters of the UE. The one or more parameters can include, without limitation, a modulation scheme used for communication with the UE, a modulation and coding scheme (MCS) used for communication with the UE, a distance of the UE relative to the base station, an antenna configuration at the UE, interference management capability of the UE, and a rank of the UE.

Abstract: Embodiments provide approaches for sub-sampling a two-component precoder codebook to reduce the overhead associated with signaling the codebook in periodic Channel State Information (CSI) reports from a user equipment (UE) to a base station. In one embodiment, a first component of the codebook is sub-sampled to accommodate a payload capacity of a Physical Uplink Control Channel (PUCCH) CSI Report of Type 1. In another embodiment, both the first component and the second component of the codebook are sub-sampled to accommodate a maximum payload capacity associated with a PUCCH CSI report.
