Webb22 maj 2024 · Principle of Phase Shift Keying Binary Phase Shift Keying The most straightforward type of PSK is called binary phase shift keying (BPSK), where “binary” refers to the use of two-phase offsets (one for logic high, one for logic low). WebbAspects of the disclosure relate to maintaining, defining, configuring and implementing a coverage enhancement mode defined for radio access network. A base station may maintain parameters that define multiple coverage enhancement modes in a lookup table and may select a first coverage enhancement mode from the two or more coverage …
