In a general aspect, a rate at which MIMO transmissions are elicited from wireless communication devices is varied. A first wireless communication device may be configured to wirelessly transmit a first set of messages at a first transmission rate to a second wireless communication device. The first wireless communication device may further be configured to receive MIMO transmissions from the second wireless communication device. The first wireless communication device may additionally be configured to generate first channel information based on respective training fields in each of the first MIMO transmissions; determine a rate at which the first channel information is generated; vary the first transmission rate to a second, different transmission rate based on the rate at which the first channel information is generated; and wirelessly transmit a second set of messages at the second transmission rate to the second wireless communication device.

A wireless device receives configuration parameters indicating: a first cell carries scheduling information for first packets received via the first cell; and a second cell carries scheduling information for second packets transmitted via the first cell. A downlink control information (DCI) for transmission via the first cell is received. A determination is made whether the DCI is for uplink transmission or downlink transmission. Based on the determining, a deactivation timer of the second cell is restarted or not restarted. In response to the deactivation timer of the second cell expiring, the second cell is deactivated.

Provided are a method and device for determining a power control parameter, and storage medium. The method includes: determining a beam state of an uplink transmission; and determining, based on the beam state, the power control parameter of the uplink transmission, where the beam state at least includes one of the following: a QCL state, a TCL state, spatial relation information, reference signal information, spatial filter information or precoding information.

A wireless device receives configuration parameters of a primary cell and a secondary cell. In response to the secondary cell cross-carrier scheduling the primary cell, the wireless device determines radio link monitoring reference signals based on: one or more first control resource sets (coresets) of the primary cell and one or more second coresets of the secondary cell. The wireless device measures the radio link monitoring reference signals for radio link monitoring of the primary cell.

This application provides a terminal device and a communication method. The terminal device is in a dual-connectivity network including a long term evolution (LTE) link and a new radio (NR) link, and when the terminal device detects that the terminal device is in a power saving mode, and/or when the terminal device detects that battery power of the terminal device is less than or equal to a first preset value, and/or when the terminal device detects that temperature of a rear cover of the terminal device is greater than or equal to a second preset value, the terminal device releases the NR link, and uses the LTE link for communication.

The present disclosure relates to a communication technique that merges IoT technology with a 5G communication system for supporting higher data transmission rates than 4G systems, and a system therefor. The present disclosure may be applied to intelligent services (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, healthcare, digital education, retail business, security and safety-related services, etc.) on the basis of 5G communication technology and IoT∼-related technology. The present invention discloses a method and device for setting and applying a plurality of Discontinuous receptions (DRXs).

This disclosure describes systems, methods, and devices related to enhanced time synchronization. A device may define a reference device as a reference access point (AP) or a reference AP multi-link device (MLD). The device may cause to send a TSF alignment request frame to a responder AP to align its TSF with an initiator AP for coordinated target wake time (TWT) or a restricted TWT (rTWT) service periods (SPs). The device may identify a TSF alignment response frame received from the responder AP in response to the TSF alignment request frame.

Methods and apparatuses for low-latency traffic identification. A method for wireless communication performed by a non-access point (AP) station comprises: receiving frames containing information pertaining to target wake time (TWT) from a corresponding AP; receiving information associated with a restricted target wake time (R-TWT) from the AP; determining whether a traffic identifier (TID) is indicated in a R-TWT Traffic Info field of an R-TWT Parameter Set field in a TWT element; and determining, based on whether the TID is indicated, whether to transmit a quality of service (QoS) Characteristics element corresponding to the TID to the AP.

Disclosed are channel monitoring and a control method and apparatus thereof, for achieving an adaptive Physical Downlink Control Channel (PDCCH) monitoring solution, achieving adaptive adjustment of PDCCH monitoring according to a service condition of a terminal, and achieving an effect of power saving of the terminal. The channel monitoring control method provided in the present application comprises: determining PDCCH monitoring solution instruction information; and sending the PDCCH monitoring solution instruction information to the terminal for instructing the terminal to adjust the PDCCH monitoring solution.

A DRX control method and apparatus may flexibly control active times of different DRXs when a plurality of DRXs is configured for a terminal device. For example, a network device may send indication information to the terminal device in a first serving cell of the terminal device, to configure the terminal device to start, prolong, or end DRX active time of a second serving cell of the terminal device. The first serving cell is configured with a first DRX, and the second serving cell is configured with a second DRX. The network device sends indication information based on the first DRX.
