Abstract: A technique of performing a RACK procedure includes a framework for a two-step RACK in which a first message (MsgA) from the UE to the gNB has data carrying resources (i.e., PUSCH) is organized into a time-frequency array defined by a mapping to a plurality of preambles. Such a two-step RACK has less latency than the four-step RACK due to fewer signaling exchanges. Moreover, this two-step RACK also causes the UE to use less power due to a decreased signaling overhead.

Abstract: Certain embodiments may relate to communication systems, and, for example, some embodiments may relate to beamforming techniques. According to an embodiment, a method may include, for each PDCCH search space candidate, one or more UE beams may be configured and/or assigned that correspond to one or more of the configured beam pairs. For each PDCCH search space candidate, one or more beam pairs, based on one or more corresponding downlink RS for beam management, may correspond to a configured UE beam. The UE may detect a PDCCH. Upon detecting a PDCCH, the UE can identify one or more configured beam pairs or a default beam pair within the PDCCH search space candidates.

Abstract: A user equipment (UE) selects first and second radio resources from respective first and second pools of radio resources. In one example these are primarily allocated for contention-free and scheduling-based channel access, respectively. Content to duplicate in parallel communications is selected based at least on a characteristic of uplink data waiting to be sent (such as size) and/or on the selected first and second radio resources (such as timing difference between them). The UE transmits the selected content on each of the selected first and second radio resources. In the examples the content to duplicate was selected from among the uplink data to send and a scheduling request message. In various embodiments one of these transmissions indicates it's a duplicate, and the duplicated scheduling request message is transmitted on the first resource with the uplink data. These teachings are particularly useful for URLLC data.

Abstract: Fallback aspects associated with the power ramping procedure are addressed. More specifically, a set of control mechanisms allows for a gNB to adjust thresholds for controlling the UE transfer from a 2-step RACH procedure to a 4-step RACH procedure while still maintaining a proper setting for transmit power during this transition. The mechanism will allow for a UE to have a smooth transition to the 4-step procedure instead of having to start the power ramping from scratch when transferring to the fall-back routine.

Abstract: Example embodiments of the present disclosure relate to information transmission in random access. A method comprises selecting, one of a plurality of random access preambles that is received from a terminal device, the plurality of random access preambles being divided into a plurality of subsets of random access preambles; selecting at least one predefined sequence associated with the selected random access preamble based on a predetermined association between a plurality of predefined sequences and the plurality of subsets of random access preambles and based on a target resource unit to be used for transmission of control information and data information; modulating the control information with one of the at least one predefined sequence, the control information indicating configuration of the data information; and transmitting the selected random access preamble, the modulated control information, and the data information in a random access message to the network device.

Abstract: A method, apparatus, and a computer-readable storage medium for beam refinement of a two-step random access channel (RACH) procedure are provided. In some implementations, the method may include receiving a plurality of synchronization signal blocks (SSBs), a plurality of channel state information-reference signals (CSI-RSs) associated with each of the plurality of synchronization signal blocks (SSBs), and random access channel (RACH) configuration data from a gNB. The method may further include transmitting a first message of the two-step random access channel (RACH) procedure to the gNB, the first message including a first portion and a second portion. The first portion includes a preamble associated with a selected channel state information-reference signal (CSI-RS) of the plurality of channel state information-reference signals (CSI-RSs) and the second portion includes data associated with the preamble, and the data transmitted using pre-configured or pre-allocated resources.
