A method performed by a terminal in a communication system is provided. The method includes identifying a first physical downlink shared channel (PDSCH) scheduled by a physical downlink control channel (PDCCH), and a second PDSCH without a corresponding PDCCH; identifying that the first PDSCH and the second PDSCH are overlapped in time; and decoding the first PDSCH on a basis that the PDCCH scheduling the first PDSCH ends at least 14 symbols before the starting symbol of the second PDSCH.

The present embodiments relate to a method and device for obtaining location information of a terminal by using a wireless communication system. Provided according to an embodiment is a device for acquiring the location information of a terminal, the device comprising at least one downlink signal receiver, at least one uplink signal receiver, and a controller for controlling the downlink signal receiver and uplink signal receiver, wherein the controller configures uplink resource assignment information on the basis of control information received by the downlink signal receiver and determines whether an uplink signal is received, on the basis of the uplink resource allocation information.

A method for transmitting downlink control information (DCI) includes: transmitting DCI based on modulation coding strategy (MCS) corresponding to user equipment (UE); in which the DCI includes a first-type DCI or a second-type DCI, the first-type DCI includes a first MCS field and a first repeating number indication field; and the second-type DCI includes a second MCS field and a second repeating number indication field.

A terminal includes a receiving unit that receives, through a first component carrier of a plurality of component carriers forming carrier aggregation, scheduling information for one or more second component carriers of the plurality of component carriers; and a control unit that configures rate matching on the one or more second component carriers, based on configuration information on the rate matching included in the scheduling information.

A method of wireless communication by a device includes detecting whether the device is in an outdoor environment in response to a start of a reevaluation timer. The method also determines a mobility level of the device in response to the start of the reevaluation timer. The method further includes enabling a vehicle-to-everything (V2X) pedestrian mode in response to the device being in the outdoor environment and/or the mobility level exceeding a threshold value.

Methods, systems, and devices for wireless communication are described. A wireless communications system may support one or more communication devices (e.g., user equipment (UE)) operating according to an aperiodic (e.g., and dynamic) discontinuous reception (DRX) mode. For example, a UE may communicate with a device in the wireless communications system (e.g., a base station, another UE) according to a periodic DRX mode. In response to a transition indication, the UE may dynamically transition to the aperiodic DRX mode and may operate according to the aperiodic DRX mode for a duration. To operate according to the aperiodic DRX mode, the UE may be configured to disable a first set of communication operations for the duration, perform a second set of communication operations during the duration, or a combination thereof (e.g., across component carriers of a carrier group, across component carriers of a DRX group).

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an apparatus of a user equipment (UE) may receive a configuration for an aggregate component carrier. The aggregate component carrier may include a combination of multiple component carriers. The apparatus may perform a half-duplex communication utilizing the aggregate component carrier. Numerous other aspects are described.

A base station transmits a layered data signal to multiple devices that are in close proximity to each other where the layered data signal includes at least first data on a first data layer directed to a first device and second data on a second data layer directed to a second device. The base station also transmits a single control message to both devices where the control message comprises location dependent control information directed to both devices. The control message also comprises data layer control information arranged in multiple fields where data layer control information in a field is associated with a device and allows the associated device to recover the data from a data layer assigned to the device.

Systems and methods for analyzing available networks and transferring data via a two-way radio transmission are described herein. An example method may commence with collecting, by a data collection device, asset data. The method may continue with preprocessing, by the data collection device, the asset data for transmission. The method may further include dynamically analyzing, by the data collection device, networks available for transmission of the asset data determining a mode for the transmission of the asset data. The method may further include transmitting, by at least one of the data collection device and a two-way radio device communicatively coupled to the data collection device, the asset data to a data server. The asset data may be transmitted based on the mode for the transmission via at least one communication channel and at least one intermediate device.
