Wearable antenna systems in the form of suspenders are disclosed. Such communications suspenders employ antenna elements having a reduced visual signature while maintaining the load bearing functionality of traditional suspenders. The antenna system communicatively couples to portable radios that operate on different RF frequencies via a communications hub. Some of the antennas elements are dynamically positionable (i.e., swappable, switchable, etc.) on the communications suspenders. A plurality of straps are pivotably coupled to an intermediate portion at one end and a demountable fastener at the other end. The demountable fasteners couple to the user's garment item (e.g., trousers, shorts, skirts, and similar articles). The straps include RF shielding material positioned to reflect RF radiation that emanates from the antenna elements away from the user. The antenna elements are formed using a conductive composition of fully exfoliated graphene sheets present as a percolated network in a polymer matrix.

A wearable mobile phone holder includes a holding part, a base, clamping teeth and a latch. The base is pivotally connected to the holding part through a pivot shaft. The clamping teeth are arranged on the holding part, and the latch is arranged on the base. The plurality of clamping teeth are arranged along a circumferential direction of the pivot shaft. An end of the latch is inserted into a clamping teeth gap between the clamping teeth. The mobile phone can be quickly installed into or removed from the wearable mobile phone holder by only rotating the pressing head. The mobile phone can be tightly clamped and positioned by the spring in the rotary pressing mechanism, which can be easily and quickly operated. The distance between the clamping jaws can be adjusted to adapt to mobile phones of different models and sizes to improve the generality of the holder.

A communication device incorporates, and a method provides increased communication coverage for a second user device. A support structure has a first spatial portion including first radio frequency (RF) antenna(s) and a second spatial portion including second RF antenna(s). The first and second RF antenna(s) are respectively on different sides of a body of a person for communication coverage for a received RF signal. The first and second RF antenna(s) are spaced apart on the support structure for reduced interference from inter-antenna coupling. A communication subsystem demodulates the RF signal to a baseband signal that is transmitted through a communication cable to a second user device with low data latency.

The present disclosure provides a method of generating codebook in a wireless communication system with multiple antenna arrays, as well as a wireless communication system, base station and terminal using the codebook for communication. The method comprises steps of: providing a basic codebook which contains multiple pre-coding matrices; and assigning phase offsets to certain pre-coding matrices in the basic codebook to form a codebook with phase offset. The feedback overhead from a client to a base station side is reduced and a good precision of feedback for multi-antenna array is kept by applying the method of generating codebook and using the generated codebook in the wireless communication system, base station and terminal.

An electronic device may be provided with a display. The display may have a flexible display layer covered by a protective display cover layer. The flexible display layer may be an organic light-emitting diode display layer or other layer with a flexible substrate. The flexible display layer may have a central region with peripheral edges. The central region may be rectangular, may be octagonal, or may have other shapes. Strip-shaped protrusions may extend along each of the peripheral edges of the central region. The strip-shaped protrusions may be bent to provide the protrusions with curved surface profiles. The display cover layer may have a cushion shape with bowed edges that overlap parts of the strip-shaped protrusions, may have curved inner and outer surfaces and/or planar surfaces, may have rounded corners with compound curvature, may have edges with curved surface profiles, and/or may have other configurations.
