USER EQUIPMENT AND METHODS FOR CODEBOOK SUBSAMPLING FOR ENHANCED 4TX CODEBOOKS
摘要:
Embodiments of user equipment (UE) and methods for codebook subsampling for enhanced 4TX codebooks in 3GPP LTE wireless networks are generally described herein. In some embodiments, a physical uplink control channel (PUCCH) is configured for transmission of channel state information (CSI) feedback including a rank indicator (RI) and a precoding matrix (W1). The rank indicator (RI) and a precoding matrix (W1) are jointly encoded and codebook subsampling is performed for the enhanced 4Tx codebook for at least one of: PUCCH report type 5 (RI/1st PMI) in PUCCH 1-1 submode 1; PUCCH report type 2c (CQI/1st PMI/2nd PMI) in PUCCH 1-1 submode 2; and PUCCH report type 1a (subband CQI/2nd PMI) in PUCCH 2-1.
