A transmission power for a wireless communication may be determined based on one or more criteria. A default transmission power may be based on one or more default transmission power control parameters indicated by a base station. One or more default transmission power control parameters may be determined, for a transmission by a wireless device, based on whether the transmission is via a serving cell or via a non-serving cell.

A control resource set processing method is provided. In the method: a terminal switches a configuration of a control resource set on an unlicensed spectrum for detecting a control signaling in response to determining that a switching condition for the control resource set is met.

Apparatuses, methods, and systems are disclosed for transmission using an adapted downlink waveform type. One method (3400) includes dynamically or semi-statically adapting (3402) a downlink waveform type at a network unit, wherein: the downlink waveform type comprises a multi-carrier waveform, a single-carrier waveform, or a combination thereof; and the downlink waveform type is for a transmission comprising a synchronization signal block transmission, a physical downlink scheduled channel transmission, or a combination thereof. The method (3400) includes transmitting (3404) the transmission using a downlink waveform pattern comprising the downlink waveform type.

Methods and apparatus for communicating and utilizing persistent allocation of resources are described herein. A base station may allocate persistent resources to a client station, and may associate the client station or persistent resource allocation with a particular shared NACK channel. The base station may monitor the NACK channel for a NACK indicating a map error. The base station may monitor the resource allocation to implicitly determine a map error. The base station may resend one or more persistent resource allocation information elements in response to the NACK or implicit error determination. A client station having a persistent resource allocation may monitor persistent resource allocation information elements in map messages and/or may indicate failure to receive a persistent resource allocation information element in a NACK message on a shared NACK channel.

A user terminal supporting carrier aggregation (CA) and an operating method thereof are provided. The operating method includes receiving indication information regarding a phase tracking reference signal (PTRS) component carrier (CC) group from a base station; determining whether a phase noise characteristic of the user terminal is the same with respect to CCs included in the PTRS CC group, based at least in part on the indication information; requesting the base station to transmit at least one PTRS using at least one CC included in the PTRS CC group; and receiving the at least one PTRS from the base station using the at least one CC.

A method of wireless communication by a user equipment (UE) includes reporting, to a base station, a requested downlink code block mapping, which has a defined duration. The method also includes receiving a first code block from the base station during the defined period of time. The method further includes receiving a second code block from the base station during the period of time. The method further includes decoding the first code block with a first demodulator according to the code block mapping. The method still further includes decoding the second code block with a second demodulator, which is different from the first demodulator, according to the code block mapping.

The present application discloses a method for data transmission, a terminal device, and a network device. The method can include receiving first control information for scheduling a terminal device to perform data transmission; and determining at least one transmission frequency band corresponding to the transmission information. The first mapping relationship can include a correspondence between a plurality of pieces of transmission information and a plurality of transmission frequency bands, and the transmission information can include at least one of: an attribute of the first control information, resource type information for the data transmission, and traffic information of the terminal device. The terminal device can determine a target transmission frequency band from the at least one transmission frequency band, and transmit data with the network device on the target transmission frequency band according to the first control information.

A DCI transmission method is provided, which includes: transmitting configuration information that is used for allocating N search space sets; dropping part or all of PDCCH candidates of at least one search space in a first search space set in a case that the number of PDCCH candidates in the first search space set is greater than a maximum number of PDCCH candidates supported by a terminal, to obtain a second search space set; and transmitting DCI on the second search space set; where the first search space set includes a first search space, the first search space is a search space for scheduling a second cell by a first cell, the first cell is a secondary cell, and the number of PDCCH candidates in the second search space set is less than or equal to the maximum number of PDCCH candidates supported by the terminal.

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for measurement without gaps for narrow bandwidth part (BWP) hopping. A user equipment (UE) may measure one or more synchronization signal blocks (SSBs) while performing BWP hopping according to a hopping pattern. The UE may receive data and measure an SSB in a same frequency hop during a same measurement window without a gap. A base station (BS) may transmit a control message to the UE to configure an active BWP for the UE, a set of measurement windows, a hopping pattern, and a set of SSBs that occur within a set of frequency hops to support the measurement without gaps. The active BWP may be defined for measurement purposes to reduce ambiguity. The control message may support alignment of a measurement window with an active frequency hop to support measurement without gaps.

A method for information transmission includes: receiving a first request message carrying a recommended positioning reference signal (PRS) configuration; determining a target PRS configuration according to the recommended PRS configuration; and sending a PRS to a user equipment by using the target PRS configuration.
