用于增强型4TX码本的码本子采样的用户设备和方法
Abstract:
本文涉及用于增强型4TX码本的码本子采样的用户设备和方法，一般地描述了用于在3GPP LTE无线网络中针对增强型4TX码本进行码本子采样的UE和方法的实施例。在一些实施例中，PUCCH被配置用于传输CSI反馈，CSI反馈包括RI和预编码矩阵(W1)。RI和W1被联合编码，并且针对以下各项中的至少一个针对增强型4Tx码本执行码本子采样：PUCCH 1-1子模式1中的PUCCH报告类型5(RI/第一PMI)；PUCCH 1-1子模式2中的PUCCH报告类型2c(CQI/第一PMI/第二PMI)；以及PUCCH 2-1中的PUCCH报告类型1a(子带CQI/第二PMI)。
Abstract(English):

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.
