Abstract
In one of its aspects the technology disclosed herein concerns a communications system comprising an access node (22) and a wireless terminal (26). A wireless terminal comprises receiver circuitry and processor circuitry. The receiver circuitry receives wireless communications over an air interface from a radio access network. The processor circuitry changes from using a first periodicity to using a second periodicity to detect a synchronization signal included in the received wireless communications.

A terminal apparatus comprising:
- receiver circuitry configured to receive, from a base station apparatus, dedicated signaling comprising first information used for configuring a first periodicity, the first periodicity being for a first measurement timing;
- and
- processor circuitry configured to perform, based on the first periodicity, a measurement based on a first block comprising a primary synchronization signal (PSS), a secondary synchronization signal (SSS) and a physical broadcast channel (PBCH);
- wherein:
- the receiver circuitry is configured to receive, from the base station apparatus, the dedicated signaling comprising second information used for configuring a second periodicity, the second periodicity being for a second measurement timing,
- the processor circuitry is configured to perform, based on the second periodicity, the measurement based on a second block comprising a PSS, a SSS and a PBCH, and
- a value of the second periodicity is always configured as a value smaller than a value of the first periodicity.
