The present invention presents a method for efficiently estimating a physical channel and, according to the present invention, a terminal of a communication system receives a synchronization signal from a base station, receives a broadcast channel from the base station, and can estimate the broadcast channel on the basis of the synchronization signal.

Disclosed is a method performed by a network node, for an enhanced paging of a wireless device of a set of wireless devices. The method comprises controlling transmission, to the set of wireless devices, of a first paging message in a first paging period. The method comprises transmitting, to the set of wireless devices, in at least one physical signal between the first paging period and a second paging period succeeding the first paging period, control signaling indicating a change in paging of the second paging period, wherein the change in paging is with respect to the first paging period. The method comprises controlling, in accordance with the indicated change, transmission, to the set of wireless devices, of a second paging message in the second paging period.

A method for processing a time synchronization packet is provided. In an embodiment a terminal device receives a time synchronization packet of a first clock source from an external device; receives first indication information from a network device, where the first indication information instructs the terminal device to enter a time synchronization activated state of the first clock source, or the first indication information instructs the terminal device to enter a time synchronization deactivated state of the first clock source; and processes the time synchronization packet of the first clock source based on the first indication information. When a clock source is activated and deactivated, the terminal device processes a time synchronization packet of the clock source in different manners, and signaling indicates whether the clock source is activated or deactivated.

Methods, systems, and devices for wireless communications are described. A base station may determine to operate in accordance with an energy saving mode in which the base station only transmits remaining minimum system information (RMSI) on-demand or reduces transmission of RMSI with respect to when the base station is operating outside of the energy saving mode. A user equipment (UE) may detect the base station that is operating in an energy saving mode. The UE may transmit a request for the base station to transmit the RMSI to the UE, where the UE may transmit the request to the energy saving base station or to a serving base station of the UE. The UE may receive, from the base station operating in the energy saving mode and responsive to the request, a message including the remaining minimum system information.

One example discloses a near-field wireless communications device, including: a near-field antenna; a near-field noise detector coupled to receive a first set of near-field signals from the near-field antenna; wherein the near-field noise detector is configured to identify a set of attributes of the near-field noise within the first set of near-field signals; a controller configured to generate at least one synchronization signal based on at least one of the attributes of the near-field noise; and a transmitter circuit configured to transmit a second set of near-field signals in response to the synchronization signal.

Example systems, apparatus, and methods receive audio information including a plurality of frames from a source device, wherein each frame of the plurality of frames includes one or more audio samples and a time stamp indicating when to play the one or more audio samples of the respective frame. In an example, the time stamp is updated for each of the plurality of frames using a time differential value determined between clock information received from the source device and clock information associated with the device. The updated time stamp is stored for each of the plurality of frames, and the audio information is output based on the plurality of frames and associated updated time stamps. A number of samples per frame to be output is adjusted based on a comparison between the updated time stamp for the frame and a predicted time value for play back of the frame.
