Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a plurality regulation requirement parameters corresponding to an unlicensed carrier, where the unlicensed carrier spans at least a portion of a first unlicensed band associated with a first set of regulation requirements and at least a portion of a second unlicensed band associated with a second set of regulation requirements. The UE may identify, from the plurality of regulation requirement parameters, a set of regulation requirement parameters for an uplink transmission based at least in part on whether a set of frequency resources for the uplink transmission overlaps with the first unlicensed band and the second unlicensed band. The UE may transmit the uplink transmission using the set of regulation requirement parameters.

Improvement of use efficiency of radio resources is realizable. An information processing device is an information processing device which includes a reception unit and a control unit. The reception unit included in this information processing device is a reception unit which receives a packet. In addition, the control unit included in the information processing device is a control unit which controls a packet monitoring state of the information processing device in case of detection of reception of a packet not addressed to the information processing device. The packet monitoring state is controlled on the basis of reception power at the time of reception of the packet not addressed to the information processing device.

An information processing device includes a control unit. A first device that transmits data to the information processing device has a multiplexing function for multiplexing and transmitting data from a plurality of devices including the first device to the information processing device. The control unit provided in the information processing device performs control to tell the first device having the multiplexing function a multiplexing method for notification information and presence of data addressed to the first device. The notification information indicates that the first device has shifted from a functional suspension state to a data receivable state. The information processing device can reduce power consumption.

A wireless local area network (WLAN) station receiver has a center frequency offset (CFO) estimator and an CFO table with an association between a CFO value from a recently received access point packet for which the station is associated according to 802.11. The receiver performs a comparison between the CFO estimate of the received packet and the CFO value from the CFO database, and powers the receiver down if the comparison exceeds a threshold. The threshold may be an absolute value in parts per million, or may include a time drift compensation component.

A method includes: receiving, at a first layer of a protocol stack, multiple code blocks from a base station, the multiple code blocks is a portion of a transport block and is associated with an error rate; transmitting, to a second layer of the protocol stack, the multiple code blocks; and determining, at the second layer and based on the error rate, whether to (1) store the multiple code blocks in memory or (2) process the multiple code blocks. A method for saving power in a physical (PHY) layer-to-medium access (MAC) layer interface and a network device, and a system are also provided.

The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system or networks beyond 5G communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology. A method of a User Equipment (UE) in a wireless communication system, the method comprising: receiving, from a base station, configuration information on reporting assistance information associated with an overheating; detecting the overheating; and transmitting, to the base station, the assistance information including first information for controlling a bandwidth associated with at least one of a first frequency range or a second frequency range based on UE's preference, wherein a first frequency corresponding to the first frequency range is smaller than a second frequency corresponding to the second frequency range.

Certain aspects of the present disclosure provide techniques for handling acknowledgement and retransmission timers during sidelink discontinuous reception (DRX) communication. An example method by a transmitter user equipment (UE) generally includes transmitting a first repetition of a physical sidelink shared channel (PSSCH) to a receiver UE prior to entering an inactive state, while the transmitter UE is operating in a sidelink discontinuous reception (DRX) mode; returning to an active state to monitor for acknowledgment feedback from the receiver UE, wherein the return is based on a first timer relative to an end of the first repetition of the PSSCH; remaining in the active state for a duration defined by a second timer; and taking one or more actions depending on whether the transmitter UE receives acknowledgment feedback during the duration indicating failed reception of the first repetition of the PSSCH by the receiver UE.

A method of canceling interference by a signal receiving apparatus in a communication system supporting a multi-user Multiple-Input Multiple-Output (MIMO) scheme and a signal receiving apparatus is provided. The method includes determining whether there is a need for using an interference cancellation scheme while performing a signal detecting operation; and performing the signal detecting operation using the interference cancellation scheme, or performing the signal detecting operation without using the interference cancellation scheme based on determining whether there is the need for using the interference cancellation scheme.

A method and device for sending downlink information are provided. Specified information to be sent to User Equipment (UE) is determined, and the specified information may include at least one of: system message change information, Earthquake and Tsunami Warning System (ETWS) notification information, Commercial Mobile Alert Service (CMAS) notification information or Extended Access Barring (EAB) parameter change notification information. The specified information is sent to the UE according to a predetermined manner, and the predetermined manner is different from a manner of sending the specified information through a paging message.

The invention relates to a method and an arrangement for reducing power consumption of a receiver in a mobile communication network comprising a sender transmitting packet data on a downlink channel to one or more receivers over a radio interface. Inactive time instants and listening time instants are defined according to provided rules. The receiver is arranged to listen for information from the sender during the listening time instants and to sleep during the inactive time instants. Thus, less power will be consumed during the inactive time instants.
