Adaptation of communication parameters for a user equipment
A UE includes a transceiver configured to receive an adaptation request (AR) via a DCI format in a PDCCH. The UE further includes a processor configured to configure the transceiver to operate in a first state associated with a reception of a first DCI format in a first search space set in response to an AR reception outcome, and to operate in a second state associated with a reception of a second DCI format in a second search space set. A BS includes a transceiver configured to transmit an AR via a DCI format in a PDCCH. The BS includes a processor configured to configure the transceiver to operate in a first state associated with a transmission of a first DCI format in a first search space set, and to operate in a second state associated with a transmission of a second DCI format in a second search space set.
METHOD AND APPARATUS FOR OPERATING IN A DISCONTINUOUS RECEPTION MODE EMPLOYING CARRIER AGGREGATION
Methods and apparatus are described. A long term evolution-advanced (LTE-A) wireless transmit/receive unit (WTRU) includes a transceiver and a processor. The transceiver receives discontinuous reception (DRX) configuration information. The processor, in response to the received DRX information, controls the transceiver to monitor LTE-A physical downlink control channels (PDCCHs) in subframes in a first frequency band during an active time. The processor further, in response to detecting a downlink assignment in an LTE-A PDCCH in the first frequency band during the active time, wherein the downlink assignment indicates a second frequency band and assigned subcarriers within the second frequency band, to receive an LTE-A physical downlink shared channel (PDSCH) K subframes after a transmission of the downlink assignment. The second frequency band is different than the first frequency band.
Method of conserving power of a battery in a battery-powered electronic device, and electronic device for performing the method in a wireless local area network
A method of and system for conserving power of a battery in a battery-powered electronic device are disclosed. The electronic device, which can be a digital camera, is wirelessly communicable with one or more access points over a wireless local area network. The electronic device is also wirelessly communicable over a plurality of frequency channels in one or more frequency bands. The method of conserving power relates to an improved roaming process. Also disclosed are an electronic device and a system for performing the method.
WLAN decodability-based frame processing for power saving
Methods, apparatus and systems are disclosed for receiving an IEEE 802.11 frame at a WLAN station, determining whether the frame is decodable and addressed to the WLAN station, and entering a reduced power state if the frame is not decodable or not addressed to the WLAN station.
Device-capability-based and standalone paging in new radio unlicensed band
A device may operate within a specified frequency band within a specified coverage area of a wireless cellular network served by a cell. The device may monitor, during a cell-specific paging window, paging messages transmitted by the cell within the cell-specific paging window to devices operating within the specified coverage area and targeted to receive paging messages. The device may enter an idle state if the monitoring indicates that the paging messages do not include a respective paging message intended for the device. If the monitoring indicates that the paging messages include a paging message intended for the device, the device may process the paging message. Furthermore, the device may indicate to the cell, when attaching to the cell, whether the device has a capability to support standalone operation within the specified frequency band. If the indication is that the device does not support such standalone operation, the cell may not issue paging messages to the device.
Wireless Communication Methods
Various wireless communication methods are provided for controlling two or more wireless devices. In one embodiment, various processes optimize the wireless communication, especially when multiple devices are present in a system or a network. In another embodiment, various controlling devices are accommodated in a network of devices at different points in time. The speed at which the new controlling device comes into a range of the networked devices is improved with existing signatures of different wireless protocols or devices present in the network. In another embodiment, a change in the signal strength of a wireless device can be used to detect an object or person, such as an intruder.
METHOD AND USER EQUIPMENT FOR PERFORMING SIDELINK COMMUNICATION
A method and a User Equipment (UE) for performing Sidelink (SL) communication are provided. The method includes performing an SL transmission based on a first set of timers configured for controlling SL Discontinuous Transmission (DTX) behaviors of the UE; and performing an SL reception based on a second set of timers configured for controlling SL Discontinuous Reception (DRX) behaviors of the UE, wherein at least one first timer value of the first set of timers is independently configured relative to at least one second timer value of the second set of timers.
POWER EFFICIENT COMMUNICATION WITH WIRELESS SMART REPEATER
A smart repeater (SMR) can be configured to amplify and forward data from a base station based on received control information for managing power efficiency of on-off operations. The SMR can configure a power control mechanism based on the control information to adapt one or more bandwidths associated with the SMR based on the control information to save power and forward the communications to the base station or the UE. The control information can include a component carrier (CC) index or a bandwidth part (BWP) identifier (ID), and a set of parameters to configure on-off operations of the one or more bandwidths according to one or more CCs or BWPs.
Selective listening for a tracking reference signal (TRS) during connected mode discontinuous reception (CDRx)
A device may selectively listen for a tracking reference signal (TRS) during connected mode discontinuous reception (CDRx) based on whether the device is to switch between repeaters of a base station (such as during travel). A device may determine whether the device is in a high speed train (HST) scenario (such as based on a difference in frequency errors generated using a synchronization signal block (SSB) and generated using a TRS, based on a trajectory of a frequency error or a frequency error difference over time, based on instantaneous frequency errors, etc.). When the device is in a HST scenario, the device listens for a TRS during CDRx, and the device generates a frequency error using the TRS. When the device is not in a HST scenario, the device prevents listening for a TRS during CDRx (with a SSB received during CDRx to be used to generate a frequency error).
Radio communications
A radio transceiver comprises one or more hardware resources, e.g. a processor; memory; a peripheral device; an algorithmic hardware accelerator; and/or a radio frequency component. A cellular communication radio is operable in an active mode in which it has access to the one or more hardware resources for transmitting and/or receiving cellular communication signals, and an inactive mode in which it does not. A global navigation satellite systems radio, arranged to use the one or more hardware resources to receive positioning signals, has access to the one or more hardware resources only when the cellular communication radio is operated in the inactive mode.
