Synchronization signal detection and transmission for radio system
View Patent ↗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.
1. 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.
2. The terminal apparatus according to claim 1 , wherein the second information is different from the first information.
3. A method in a terminal apparatus comprising:
receiving, 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;
performing, 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);
receiving, 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,
performing, 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.
4. The method of claim 3 , wherein the second information is different from the first information.
5. A base station apparatus comprising:
transmitter circuitry configured to transmit dedicated signaling comprising first information used for configuring a first periodicity, the first periodicity being for a first measurement timing of a first block comprising a primary synchronization signal (PSS), a secondary synchronization signal (SSS) and a physical broadcast channel (PBCH);
wherein the transmitter circuitry is configured to transmit the dedicated signaling comprising second information used for configuring a second periodicity, the second periodicity being for a second measurement timing of a second block comprising a PSS, a SSS and a PBCH, and wherein a value of the second periodicity is always configured as a value smaller than a value of the first periodicity.
6. The base station apparatus according to claim 5 , wherein the second information is different from the first information.
7. A method in a base station apparatus comprising:
transmitting dedicated signaling comprising first information used for configuring a first periodicity, the first periodicity being for a first measurement timing of a first block comprising a primary synchronization signal (PSS), a secondary synchronization signal (SSS) and a physical broadcast channel (PBCH);
transmitting the dedicated signaling comprising second information used for configuring a second periodicity, the second periodicity being for a second measurement timing of 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.
8. The method of claim 7 , wherein the second information is different from the first information.
