Disclosure provides a method and device in a node for wireless communications. A first receiver, receives a first signaling; and a first transmitter, transmits a first signal in a target time-frequency-resource block, and the first signal carries a second bit block; herein, the first signaling is used to determine a first bit block; the first bit block comprises a second-type HARQ-ACK; the first bit block is used to generate the second bit block; the first time-frequency-resource block and the second time-frequency-resource block are respectively reserved for different bit blocks; a number of resources used to transmit a first-type HARQ-ACK in the first time-frequency-resource block is used to determine whether the target time-frequency-resource block is the first time-frequency-resource block or the second time-frequency-resource block; the first-type HARQ-ACK corresponds to a first index; the second-type HARQ-ACK corresponds to a second index; the first signaling indicates the second index.

Methods and apparatuses for signal transmission and reception are provided for a wireless communication system. Information for configuring a plurality of physical uplink control channel (PUCCH) resources is transmitted to a terminal. Downlink control information (DCI) is transmitted to the terminal on a physical downlink control channel (PDCCH). The DCI includes a resource indicator for indicating a PUCCH resource among the plurality of PUCCH resources. Uplink control information (UCI) is received from the terminal on the PUCCH resource indicated by the resource indicator.

A method for communication is applied to a first terminal, and includes: obtaining a notification message sent by a network device, the notification message being used for notifying a determined collaborative terminal, and the collaborative terminal being a second terminal different from the first terminal; and determining, based on the notification message, the second terminal for assisting the first terminal in transmitting data. The examples of the disclosure can effectively improve the coverage performance.

The disclosure relates to a method and a device for determining a path-loss reference signal. The method includes: obtaining downlink control information (DCI) for scheduling a data channel; and determining a path-loss reference signal of the data channel according to a format of the DCI in combination with a type of a reference signal associated with the data channel or a transmission configuration indicator (TCI) state parameter of the data channel.

A method carried out in a User Equipment, UE, (1) for establishing communication with a wireless network (100) using inter-band Carrier Aggregation, CA, comprising: transmitting (610), to the wireless network, information identifying capabilities (51) of the UE to perform beam management of multiple Component Carriers, CC; receiving (612), from a base station (110) of the wireless network, dependent on the capabilities, information (52) indicative of co-location properties of a first CC in a first band and a second CC in a second band; establishing (617) communication between the UE (1) and the wireless network (100) using the first and the second CC.

An operating method of a terminal configured to perform vehicle-to-everything (V2X) communication in a wireless communication system, including signaling a maximum physical sidelink feedback channel (PSFCH) receiving capability to a base station; and receiving a wireless signal transmitted from the base station based on the maximum PSFCH receiving capability, wherein the maximum PSFCH receiving capability is a maximum number of PSFCHs receivable during one time transmission interval (TTI).

A method for determining a transport block size includes: determining an overhead of a sidelink data channel PSSCH demodulation reference signal (DMRS) in a physical resource block (PRB) of a first time-frequency resource, where the first time-frequency resource includes a first time unit in time domain; and determining, based on the overhead of the PSSCH DMRS, a number of resource elements (REs) on the first time-frequency resource that are for data transmission, where the number of REs for data transmission is for determining a transport block size (TBS) of the sidelink data channel PSSCH. The method provides a combined gain of a plurality of transmissions of a same transport block, and supports DMRS configurations of different quantities of DMRS symbols in initial transmission and retransmission of one transport block.

Disclosure discloses a method and a device in a node for wireless communications. A first node receives first information; and transmits a first signaling in a first sub-channel; the first information indicates a first resource pool; the first sub-channel is one of L sub-channels, and frequency-domain resource blocks comprised by any one of the L sub-channels belong to the first resource pool; a first candidate sub-channel and a second candidate sub-channel are two different sub-channels among the L sub-channels, a frequency-domain resource block comprised by the first candidate sub-channel and a frequency-domain resource block comprised by the second candidate sub-channel are the same; either of the first candidate sub-channel and the second candidate sub-channel belongs to a target sub-channel group, the target sub-channel group comprising at least one sub-channel. The present disclosure makes full use of all resources available in the sidelink resource pool.

The present application relates to a method and apparatus for downlink data reception. one embodiment of the subject application provides a method, comprising: determining one or more control resource sets from a plurality of control resource sets in response to first Downlink Control Information (DCI) being received in at least one of the one or more control resource sets; and detecting second DCI only in the determined one or more control resource sets within a time duration.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine to not support one or more downlink control information communications for dynamic slot format determination, and determine a slot format based at least in part on radio resource control signaling from a network. Numerous other aspects are provided.
