A terminal apparatus transmits a predetermined message to a base station apparatus based on a two-step random access procedure, upon receiving one signal that is transmitted from the base station apparatus in response to the predetermined message, and includes pieces of upper layer control information for the terminal apparatus and another terminal apparatus in a multiplexed manner, specifies a first radio resource for transmitting a first response signal indicating whether or not succeeded in receiving control information that is for the terminal apparatus and is included in the one signal, and is different from a second radio resource for transmitting a second response signal for the other terminal apparatus, based on at least one of a control signal that is used for transmitting the one signal and the one signal, and transmits the first response signal using the first radio resource.

A radio access network (RAN) and a user equipment (UE) can implement a method for managing small data transmission (SDT). The method includes: (i) determining that the UE should operate in a state of a protocol for controlling radio resources in which the UE is not connected to the RAN (704); (ii) generating, based at least on whether the UE supports a first type of SDT that relies on a random access procedure and/or a second type of SDT that relies on a resource previously allocated to the UE, a message that causes the UE to communicate small data in accordance with a capability of the UE (706, 708, and 710); and (iii) transmitting the message to the UE (712).

This disclosure provides systems, methods, and devices for wireless communication that support power allocation or resource allocation for non-orthogonal multiple access (NOMA). In a first aspect, a method of wireless communication includes a user equipment (UE) randomly selecting a parameter value associated with a power level of multiple power target levels, and transmitting, to a network entity and using the power level, an uplink communication. In a second aspect, a method of wireless communication includes a UE receiving, from a network entity, an indicator that indicates multiple resource candidates, each resource candidate of the multiple resource candidates overlaps with at least one other resource candidate of the multiple resource candidates, and transmitting, to the network entity and using a resource candidate of the multiple resource candidates, an uplink communication. Other aspects and features are also claimed and described.

The method includes: a terminal device receiving first information sent by a network device, where the first information indicates a first timer, and the first timer has a first duration of performing small data transmission (SDT) using a first transmission resource, where the first duration is shorter than a second duration of a second timer, and the second duration is a duration related to a of SDT performed by the terminal device.

An operating parameter configuration method includes receiving, by an intelligent signal amplifier, a first broadcast message from a network side device, where the first broadcast message is configured to indicate that the intelligent signal amplifier is supported to access the network side device; initiating, by the intelligent signal amplifier, target random access based on the first broadcast information; and receiving, by the intelligent signal amplifier, an operating parameter from the network side device after the target random access is successful, where the target random access includes 2-step random access or 4-step random access.

A random access method includes: determining a trigger source for 2-STEP random access; and according to the trigger source for the 2-STEP random access, triggering 2-STEP random access correspondingly; where triggering 2-STEP random access includes: determining that the trigger source is beam failure recovery (BFR) for secondary cell and there are no available uplink resources, and triggering the 2-STEP random access to request the available uplink resources.
