Abstract: A Precoding-codebook-base Secure Uplink (PSU) scheme is proposed to utilize the channel reciprocity, uniqueness, and randomness in solving the secure initiation problem. A UE receives a first reference signal via first downlink channel in a mobile communication network. The UE performs channel estimation based on the first reference signal and thereby obtaining a first channel response matrix of the first downlink channel. The UE then encodes secrecy information onto a second reference signal. The UE transmits the second reference signal via a second uplink channel. The secrecy information is hidden in the uplink channel through a precoding operation such that the secrecy information can be extracted when the second uplink channel is reciprocal to the first downlink channel.

Abstract: A tempered glass screen protector includes a substrate structure, a protection structure, and an adhesion structure. The substrate structure has a transparent portion and a non-planar decorative portion extended from the transparent portion. The protection structure includes a first transparent adhesive layer disposed on the bottom surface of the transparent portion and a transparent protective layer disposed on the first transparent adhesive layer. The adhesion structure includes a first adhesive layer disposed on the bottom surface of the non-planar decorative portion, a base layer disposed on the first adhesive layer, and a second adhesive layer disposed on the base layer. The thickness of the protection structure is smaller than the thickness of the adhesion structure, so that there is no any watermark or Newton ring formed between the transparent protective layer and the display area of the portable electronic device when pressing the transparent portion.

First, at the receiver side, downlink channel state information is obtained and a set of indices of precoding matrices within a plurality of finite codebooks are selected accordingly. The selected indices of precoding matrices for each of the finite codebooks and a set of scalar coefficients are transmitted from the receiver to the transmitter. Thereafter, at the transmitter side, at least a first and a second refined precoding matrices are generated based on the selected set of indices of precoding matrices for all of the finite codebooks, and the one or more scalar coefficients and a final precoding matrix is generated at least based on the first refined precoding matrix and the second refined precoding matrix. The final precoding matrix is applied for transmission between the transmitter and the receiver.

Abstract: A pilot selection method adapted for selecting rank-2 pilot patterns for a macrocell advanced base station (ABS), a femtocell ABS and a non-macrocell and non-femtocell ABS is proposed along with a wireless communication system and a base station thereof. Different rank-2 pilot pattern is selected for a femtocell ABS from its overlay macrocell ABS and non-macrocell and non-femtocell ABS rank-2 pilot patterns. Another pilot selection method for selecting a rank-1 pilot pattern for a femtocell ABS co-located with at least a macrocell ABS is also proposed. Different rank-1 pilot pattern is selected for a femtocell ABS from its overlay macrocell ABSs using rank-1 and/or rank-2 pilot patterns, where some of the macrocell ABSs can use rank-2 pilot patterns and the rest of the macrocell ABSs just use rank-1 pilot patterns. Also, different rank-1 pilot pattern is selected for the femtocell ABS from its neighboring femtocell ABSs using rank-1 pilot patterns.
