A communication method and an apparatus includes a network device sends first information to a terminal device, so that the terminal device can determine a HARQ feedback manner based on the first information, where the HARQ feedback manner includes skipping ACK feedback and/or NACK feedback. In this manner, the network device controls the HARQ feedback manner used by the terminal device, so that the terminal device can be flexibly controlled to use different HARQ feedback manners in different scenarios, to adapt to a service constraint, effectively reduce power consumption of the terminal device, and save air interface resources.

A communication method includes a first terminal device that determines first configuration information of first discontinuous reception DRX, where the first DRX controls the first terminal device to receive data on a sidelink. The first terminal device sends the first configuration information to a second terminal device, where the second terminal device is a terminal device that establishes a sidelink connection to the first terminal device. This can reduce power consumption of the terminal device.

A transmission or reception configuration method includes: executing, according to first transmission or reception configuration information, a target behavior in a time resource configured by the first transmission or reception configuration information. The first transmission or reception configuration information is at least one set of transmission or reception configuration information in N sets of transmission or reception configuration information.

The application proposes a method for wireless data reception and a wireless device, adaptable for the wireless device to receive data from an access point. Firstly, a transceiver of the wireless device is switched on at the target beacon transmission time. Thereafter, a first portion of a beacon is received, wherein a length of the first portion is less than a complete length of the entire beacon, and the first portion comprises a time stamp and a TIM. Finally, it is determined whether a data packet needs to be received according to the TIM. If it is determined that there is no data packet to receive, the transceiver of the wireless device is switched off without completing the reception of the entire beacon.

A method for reducing power consumption of a terminal that communicates with a base station in a mobile communication system using a multi-carrier structure composed of a primary component carrier and at least one secondary component carrier comprises: receiving a discontinuous reception (DRX) parameter group for multi carriers from the base station; and setting the multi carriers to the same parameter value, by using the received parameter group. The method for reducing power consumption of the terminal further comprises: performing a downlink control channel receive operation on each carrier according to a DRX cycle. As the base station in the mobile communication system using the multi-carrier structure simplifies the DRX process for reducing power consumption of a terminal by reducing signaling load for the multi-carrier control of the terminal, it becomes possible to reduce power consumption of the terminal.

An alarm system having a portable body carried controller that wireless communicates with multiple remote base units each having a wireless communications system configured for ultralow power mode operation where the communications system is put in sleep mode greater than one half packet transmission time but no greater than preamble transmission time to conserve battery life. Controller has multiple LED-equipped buttons assigned to corresponding base units during pairing which are respectively activated when the corresponding base unit assigned thereto alarms upon occurrence of a sensor detection event. Pressing the button can turn off the LED alarm, can poll the assigned base unit, and can task the assigned base unit including to operate in flashlight mode where base unit is lit up. A preferred base unit has an enclosure with legs that form reversible pedestals upon which base unit can be placed.
