Combined wake-up signal for multiple paging occasions
A wake-up signal ( 700 - 706 ) is associated with a plurality of paging occasions ( 4901 - 4904 ) for a plurality of terminals ( 102, 102 - 1 - 102 - 8 ). Each one of the plurality of paging occasions ( 4901 - 4904 ) is associated with one or more of the plurality of terminals ( 102, 102 - 1 - 102 - 8 ).
1. A method of operating a terminal, comprising:
receiving a wake-up signal associated with a plurality of paging occasions for a plurality of terminals, each one of the plurality of paging occasions being associated with one or more of the plurality of terminals, and
in response to said receiving of the wake-up signal: listening for a paging signal at at least one paging occasion of the plurality of paging occasions,
wherein a time-frequency position of the paging occasions with respect to a time-frequency position of the wake-up signal is differently predefined for different terminals.
2. The method of claim 1 ,
wherein the wake-up signal is indicative of the plurality of paging occasions.
3. The method of claim 2 ,
wherein the wake-up signal is, for each one of the plurality of paging occasions, indicative of a time-frequency position associated with the wake-up signal.
4. The method of claim 1 ,
wherein the wake-up signal is indicative of at least one radio frame including the plurality of paging occasions.
5. The method of claim 1 ,
wherein time-frequency positions of the plurality of paging occasions are at least partly predefined.
6. The method of claim 1 ,
wherein the wake-up signal includes a bitmap indicator, each entry of the bitmap indicator being associated with one of the plurality of paging occasions and at least one of the plurality of terminals.
7. The method of claim 1 ,
wherein the wake-up signal is indicative of a mapping between the plurality of paging occasions and the plurality of terminals.
8. The method of claim 7 ,
wherein wake-up signal includes a bitmap indicator indicative of the mapping; or
wherein the wake-up signal includes a bit sequence selected from a plurality of predefined candidate bit sequences, each candidate bit sequence being associated with a respective mapping between the plurality of paging occasions and the plurality of terminals.
9. The method of claim 1 ,
wherein the wake-up signal is generated from a terminal-unspecific base sequence.
10. The method of claim 1 ,
wherein the plurality of paging occasions are offset in at least one of time domain, frequency domain, and code domain.
11. The method of claim 1 ,
wherein the wake-up signal is indicative of the plurality of terminals.
12. The method of claim 1 ,
wherein at least some of the plurality of paging occasions are for a paging of a respective terminal group comprising one or more terminals of the plurality of terminals.
13. A method of operating a base station, comprising:
transmitting a wake-up signal associated with a plurality of paging occasions for a plurality of terminals, each one of the plurality of paging occasions being associated with one or more of the plurality of terminals, and
transmitting at least one paging signal on at least one of the plurality of paging occasions for at least one of the plurality of terminals,
wherein a time-frequency position of the paging occasions with respect to a time-frequency position of the wake-up signal is differently predefined for different terminals.
14. A terminal comprising control circuitry configured to perform:
receiving a wake-up signal associated with a plurality of paging occasions for a plurality of terminals, each one of the plurality of paging occasions being associated with one or more of the plurality of terminals, and
in response to said receiving of the wake-up signal: listening for a paging signal at at least one paging occasion of the plurality of paging occasions,
wherein a time-frequency position of the paging occasions with respect to a time-frequency position of the wake-up signal is differently predefined for different terminals.
15. A base station comprising control circuitry configured to perform:
transmitting a wake-up signal associated with a plurality of paging occasions for a plurality of terminals, each one of the plurality of paging occasions being associated with one or more of the plurality of terminals, and
transmitting at least one paging signal on at least one of the plurality of paging occasions for at least one of the plurality of terminals,
wherein a time-frequency position of the paging occasions with respect to a time-frequency position of the wake-up signal is differently predefined for different terminals.
