Abstract: Embodiments of the present disclosure provide a method for improved physical downlink control channel (PDCCH) ordered physical random-access channel (PRACH) transmission in lower-layer triggered mobility (LTM). The method includes receiving a PDCCH order to initiate a PRACH transmission to at least one cell. The method also includes decoding a PRACH transmission index value, where the PRACH transmission index value describes whether the PRACH transmission is an initial transmission or a retransmission, and where the PRACH transmission index value is associated with a target downlink (DL) reference signal (RS). The method also includes determining a random access (RA) preamble power ramping counter value. The method also includes transmitting, based in part on a PRACH transmission power level, the PRACH transmission to the at least one cell, where the PRACH transmission power level is determined based in part on the RA preamble power ramping counter value.

Abstract: A user equipment apparatus (UE) includes processor(s) and memory storing instructions. The instructions, when executed by the processor(s), cause the UE at least to, establish a connection with a control network node via a serving cell, where the serving cell is supported by a source network node; receive, from the control network node and/or the source network node, timing advance (TA) cell configurations for a set of timing advance (TA) cells, where the TA cell configurations include a TA-associated random access (RA) configuration, where the set of TA cells includes first TA cells that include candidate target cells with which the UE may connect and/or other TA cells which are requested by at candidate target cells and which the UE may connect with in case the UE connects with the one of the candidate target cells; and acquire TA for the TA cell based on the TA-associated RA configuration.

Abstract: Embodiments of the present disclosure relate to reporting beam failure. A terminal device detects a beam failure on one or more serving cells of the terminal device. If the beam failure is detected on the one or more serving cells, the terminal device obtains information concerning one or more candidate beams and the one or more serving cells. Each of the one or more candidate beams is associated with a respective one of the one or more serving cells. The terminal device then transmits at least a portion of the information to a network device associated with the one or more serving cells.

Abstract: A technique of accounting for the difference in required output power reduction or required duty cycle when selecting the RO in addition to the DL RS. Both output power reduction and duty cycle are independently determined by UE itself (i.e., UE needs to be able to determine itself required power backoff and/or duty cycle in order to meet RF exposure requirements). Advantageously, a RACH procedure in which the UE determines both output power reduction and duty cycle independently enables better choices of output power reduction and duty cycle, enhancing data activity and coverage.

Abstract: Various communication systems may benefit from the appropriate selection of aspects of operation of the communication system. For example, certain wireless communication systems, such as fifth generation (5G), long term evolution advanced (LTE-A), and wireless local area network (WLAN) communication systems, may benefit from appropriate random access preamble selection. A method can include determining that a user equipment should consider at least one beam-specific parameter. The method can also include indicating to the user equipment to consider the at least one beam-specific parameter.
