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.

Disclosed are a method and apparatus for transmitting configuration information of a physical downlink control channel. The method comprises: acquiring state information of a terminal device, and generating dynamic signaling according to the state information of the terminal device, wherein the state information of the terminal device comprises service state information of the terminal device or channel state information of the terminal device; and sending the dynamic signaling to the terminal device, the dynamic signaling being used to indicate first configuration information of a search space, wherein the first configuration information is used to indicate that the terminal device monitors a physical downlink control channel (PDCCH). The technical problem of high power consumption of a terminal device in the prior art is solved.

Embodiments of this disclosure relate to the communications field, and provide a repeated transmission method and an apparatus, to increase a probability of successful decoding of a user equipment. The method includes: performing, by a user equipment, first transmission of uplink data, and sending a first reference signal to a network device based on a first transmit power, where the first reference signal is used to demodulate the first transmission of the uplink data; and performing, by the user equipment, N.sup.th transmission of the uplink data, and sending a second reference signal to the network device based on a second transmit power, where N is an integer greater than or equal to 2, the second reference signal is used to demodulate the N.sup.th transmission of the uplink data, and the second transmit power is less than the first transmit power.

An operation method of a first terminal in a communication system is provided. The method includes transmitting first SCI to a second terminal, the first SCI including one or more information elements among information indicating time resource(s) for sidelink communication, information indicating frequency resource(s) for the sidelink communication, information indicating a periodicity of physical resources for the sidelink communication, and information indicating an MCS for the sidelink communication. Second SCI is transmitted to the second terminal, the second SCI including information for an HARQ feedback operation and information indicating an NDI. The method further includes performing the sidelink communication with the second terminal based on the first SCI and the second SCI associated with the first SCI.

A method and apparatus are disclosed for configuring at least one set of beta offset values, and for each of the at least one set of beta offset values, at least one subset of beta offset values being defined for information corresponding to Uplink Control Information, UCI, and being associated with at least one service type. A method and apparatus are disclosed for obtaining a configuration of at least one set of beta offset values, for each of the at least one set of beta offset values, the configuration being associated with at least one subset of beta offset values, the at least one subset of beta offset values being defined for information corresponding to UCI and being associated with at least one service type.

A donor communication station transmits a unicast transmission comprising a plurality of device data sets where each device data set directed to each of a plurality of user equipment (UE) devices. A relay node receives the unicast transmission and retransmits the data sets in a broadcast transmission over a broadcast communication channel to the plurality of UE devices. In one example, the donor communication station encodes data for multiple user equipment (UE) devices by applying broadcast encoding to the data for each device before applying outer encoding to the data. The dual encoded data is transmitted to the relay node over a dedicated channel. The relay node applies outer decoding to the dual encoded data to retrieve the broadcast encoded data. The relay node then transmits the broadcast encoded device data in a broadcast transmission without outer encoding.

Certain aspects of the present disclosure provide techniques for indicating carrier aggregation capabilities. An example method generally includes signaling, to a base station (BS), carrier aggregation capability information indicating a capability for performing separate operations concurrently on a plurality of component carriers; receiving a carrier aggregation configuration indicating component carriers designated for the separate operations; and receiving or transmitting transmissions based on the carrier aggregation configuration.

The disclosure relates to a communication technique for combining a 5G communication system with an IoT technology to support a higher data transmission rate than a 4G system, and a system thereof. The disclosure may be applied to intelligent services (for example, services related to smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail business, security and safety, etc.) based on a 5G communication technology and an IoT-related technology. In an embodiment of the disclosure, a method performed by a terminal in a wireless communication system is provided. The method comprises: receiving, from a base station, a radio resource control (RRC) message including information on an identifier to indicate a secondary cell (Scell), information on at least one bandwidth part (BWP) of the Scell, and information including first information on a first BWP to be used as dormant BWP among the at least one BWP and second information on a second BWP to be activated as non-dormant BWP from dormant BWP; receiving, from the base station, downlink control information (DCI) including a bitmap associated with a BWP activation of the Scell; and activating a BWP identified based on the identifier, the bitmap, and at least one of the first information or the second information. According to the disclosure, via a method by which a new dormant (or hibernation) mode may be operated in units of bandwidth parts (bandwidth part-level), a carrier aggregation technology can be rapidly activated, and a battery of a terminal can be saved.

This disclosure provides systems, methods and apparatus for wireless communication. In one aspect, a multi-transmit-receive point (TRP) approach for hybrid automatic repeat request (HARQ) acknowledgment (ACK) feedback using counter downlink assignment indicators (DAIs) (cDAIs) and total DAIs (tDAIs) is provided. For example, some techniques and apparatuses described herein may provide a joint counting method in which cDAIs and tDAIs are implemented and tracked jointly between the TRPs of a multi-TRP group. This may be useful in the ideal backhaul scenario when the multi-TRP group is jointly scheduled, and may be more robust against errors than a separate counting method. Some techniques and apparatuses described herein may provide a separate counting method, in which cDAIs and tDAIs are implemented and tracked separately by the respective TRPs of a multi-TRP group.
