Abstract
Systems, methods, and devices for communicating data in a wireless communications network are described herein. In some aspects, a wireless device includes a first receiver and a second receiver. The second receiver may be configured to consume less power than the first receiver. The second receiver receives a second signal wherein the second signal comprises a wake-up signal configured in NDP format including a signal field. The wireless device includes a circuit configured to take at least one action based on the second signal.
Claims83
An apparatus for wireless communication, comprising:
- a first receiver configured to receive a paging message from a first device, the paging message configured in a null data packet (NDP) format and comprising a paging identification (P-ID) field and a direction identifier (DI) field, the P-ID field indicating an identifier of the first device, the DI field indicating whether the first device is an access point or a non-access point device;
- a processor configured to decode the paging message;
- and
- a second receiver configured to receive a beacon signal based on the paging message,
- wherein the processor is configured to transition the second receiver to an awake state via a trigger signal based on the paging message, wherein the second receiver is further configured to receive the beacon signal after the transition to the awake state, the first receiver further configured to, when in an awake state, consume less power than the second receiver when in an awake state.
An apparatus for wireless communication, comprising:
- first means for receiving a paging message from a first device, the paging message configured in a null data packet (NDP) format and comprising a paging identification (P-ID) field and a direction identifier (DI) field, the P-ID field indicating an identifier of the first device, the DI field indicating whether the first device is an access point or a non-access point device;
- means for decoding the paging message;
- second means for receiving a beacon signal based on the paging message;
- and
- means for transitioning the second receiving means to an awake state based on the paging message, wherein the second means for receiving comprises means for receiving the beacon signal after the transition to the awake state, the first means for receiving, when in an awake state, consuming less power than the second receiving means when in an awake state.
A method for wireless communication, comprising:
- receiving, via a first receiver at a first device, a paging message from a second device, the paging message configured in a null data packet (NDP) format and comprising a paging identification (P-ID) field and a direction identifier (DI) field, the P-ID field indicating an identifier of the second device, the DI field indicating whether the second device is an access point or a non-access point device;
- decoding the paging message;
- receiving a beacon signal based on the paging message, wherein receiving the beacon signal comprises receiving the beacon signal via a second receiver;
- and
- transitioning the second receiver to an awake state based on the paging message, wherein receiving the beacon signal comprises receiving the beacon signal after the transition to the awake state, the first receiver, when in an awake state, consuming less power than the second receiver when in an awake state.
A computer program product comprising a non-transitory computer readable medium encoded thereon with instructions that when executed cause a wireless communications apparatus to perform a method of wireless communication, said method comprising:
- receiving, via a first receiver, a paging message from a first device, the paging message configured in a null data packet (NDP) format and comprising a paging identification (P-ID) field and a direction identifier (DI) field, the P-ID field indicating an identifier of the first device, the DI field indicating whether the first device is an access point or a non-access point device;
- decoding the paging message;
- receiving a beacon signal based on the paging message, wherein receiving the beacon signal comprises receiving the beacon signal via a second receiver;
- and
- transitioning the second receiver to an awake state based on the paging message, wherein receiving the beacon signal comprises receiving the beacon signal after the transition to the awake state, the first receiver, when in an awake state, consuming less power than the second receiver when in an awake state.
