A method performed by a connectivity-related network entity is provided. The method includes: receiving, from a Packet Data Network (PDN) gateway and a Serving Gateway (SGW), a Short Message Service (SMS) message to be sent in a downlink; determining to use a control plane only, out of the control plane and a user plane, for transferring the SMS message; transmitting a trigger message to a user equipment to initiate establishment of connectivity with the user equipment via the control plane only and not via the user plane, wherein the user equipment starts a timer when the establishment of the control plane connectivity is initiated; receiving a response message from the user equipment; encapsulating the SMS message in a security protected Non-Access Stratum (NAS) message; and transmitting the security protected NAS message to the user equipment, in receipt of which the user equipment stops the timer.

A method and a User Equipment (UE) for performing a small data transmission are provided. The method includes receiving a Radio Resource Control (RRC) release message; transitioning to an RRC_INACTIVE state in response to receiving the RRC release message; measuring at least one Downlink (DL) Reference Signal (RS) to obtain a measurement result; selecting a particular Configure Grant (CG) resource for the small data transmission according to the measurement result; determining whether a Timing Advance (TA) value for the particular CG resource is valid for small data transmission according to (i) an amount of Reference Signal Received Power (RSRP) change of a particular DL RS associated with the particular CG resource, the particular DL RS being one of the at least one DL RS, and (ii) whether a TA-related timer is running; and performing the small data transmission on the particular CG resource after determining that the TA value is valid.

A method for network control and related products are provided, which are applied to electronic device. The electronic device includes a first network module and a second network module. The first network module is configured to be connected with a first WiFi network, a second WiFi network, or the both. A target frequency band at which the first network module interferes with the second network module is determined on condition that the first network module is connected with both the first WiFi network and the second WiFi network, when the second network module is enabled. A target WiFi network interface corresponding to the target frequency band is released, where the target WiFi network interface is at least one of following: a first WiFi network interface for a first WiFi network or a second WiFi network interface for a second WiFi network. Network connection is performed through the second network module.

A first communication device configured to communicate with a second communication device via two links comprises circuitry configured to switch between a full operation mode and a partial operation mode and control the moment of switching between the full operation mode and the partial operation mode and/or the moment of accessing the second link in the full operation mode under consideration of a switching delay indicating a delay between the initiation of switching between the full operation mode and the partial operation mode and the completion of the switching. In the full operation mode a first link of the two links is disabled and a second link of the two links commonly uses RF chains of both links for the communication with the second communication device and in the partial operation mode each link uses its RF chain for the communication with the second communication device.

A device includes one Wi-Fi chip and a first antenna and a second antenna connected to the Wi-Fi chip. The first antenna wirelessly communicates with another device in a Wi-Fi P2P manner through a first channel. The second antenna wirelessly communicates with a first wireless signal source in a Wi-Fi AP manner through a second channel. After the first channel and the second channel are two different channels on a same frequency band, time division multiplexing is performed on the first antenna and the second antenna, and a second wireless signal source whose frequency band is different from that of the first wireless signal source is detected within preset duration, the second channel is adjusted to a channel which is different from the first channel on different frequency bands, and the second antenna wirelessly communicates with the second wireless signal source in the Wi-Fi AP manner through the adjusted second channel.

Embodiments of the present application provide a method, device and system for controlling an air interface resource and relates to the field of communications, which improves air interface resource utilization. The method includes: when a core network device or user equipment detects that service data is not transmitted over a communication channel between the two devices by using an air interface resource, switching a first frequency of sending a hello packet to a peer device to a second frequency, and sending a frequency switching message to instruct the peer device also to switch the first frequency of sending a hello packet to the second frequency, so that when the hello packet is not detected within a packet detection period, an access network device releases an air interface resource occupied by a first communication channel.

Aspects described herein relate to preempting or cancelling sidelink or uplink resources of one or more devices to allow sidelink or uplink transmissions of one or more other devices, and/or determining subsequent resources for transmitting communications based on the preempted or cancelled sidelink or uplink resources. In an aspect, an indication to preempt receiving communications or cancel transmitting communications over scheduled resources can be received, and based at least in part on the indication, subsequent resources over which to receive or transmit the communications can be determined. The communications can be received or transmitted in the subsequent resources.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first slot format configuration for a first cell associated with a first radio access technology (RAT) and a first radio frequency spectrum band that conflicts with a second slot format configuration for a second cell associated with a second RAT and a second radio frequency spectrum band during at least a portion of a transmission time interval (TTI). The UE may determine that the first cell has a priority over the second cell, based on the configured slot formats or based on the radio frequency bands, and may drop a communication on the second cell based on the identified priority. The UE may then communicate during at least a portion of the TTI on the first cell while the UE drops a communication on the second cell.
