The present disclosure relates to a communication method and system for converging a 5.sup.th-Generation (5G) communication system for supporting higher data rates beyond a 4.sup.th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. Embodiments of the present invention provide a method for RACH re-attempt, a user equipment and a base station. The method comprises the steps of: by a base station, determining system configuration information and transmitting the system configuration information to a user equipment; and then, by the user equipment, transmitting a preamble sequence to perform random access, and if the random access is failed, performing RACH attempt according to the received RACH re-attempt configuration information to perform random access until a preset decision condition is satisfied. The embodiment of the present invention is used for RACH re-attempt when random access fails.

A configuration to enable a UE to utilize uplink power control parameters for when HARQ retransmission or HARQ feedback is enabled or disabled. The apparatus may receive DCI from a base station. The DCI may indicate a HARQ process number and at least one of a first set of power control parameters for a first power control mode or a second set of power control parameters for a second power control mode. The apparatus may determine whether the first or the second power control mode is to be used. The apparatus may transmit information on a PUSCH based on the first set of power control parameters or the second set of power control parameters based on the determination whether the first or second power control mode is to be used.

Facilitating a transmission power dependent resource reservation protocol in advanced networks (e.g., 5G, 6G, and beyond) is provided herein. Operations of a method can comprise defining, by a system comprising a memory and a processor, a resource reservation procedure that associates respective amounts of reserved resources available for the mobile device based on a transmission power level of the mobile device. The method also can comprise selecting, by the system, an amount of reserved resources from the respective amounts of reserved resources available based on the transmission power level of the mobile device.

A base station (BS) may receive a plurality of repetitions of a Physical Uplink Control Channel (PUCCH) from a user equipment (UE), and accumulate the received repetitions to obtain a resultant signal. The ability to accumulate repetitions enables the base station to experience a higher probability of successful recovery of the PUCCH payload bits than if decoding were based on the reception of a non-repeated transmission of the PUCCH. The base station may configure the number of repetitions, the temporal gap between the repetitions, and mode of repetition of the PUCCH. In an intra-slot mode, more than one copy may be received from each configured slot, with or without frequency hopping. In an inter-slot mode, one copy is received per configured slot. Different repetitions may be transmitted by the UE in different directions, according to a spatial consistency pattern.

An end device in a ZIGBEE communication protocol wireless network includes a memory configured to store computer-executable instructions and a processor coupled to the memory and configured to execute the instructions. The processor sends a first data frame to a first network device using a first network transmission power level and receives a first acknowledgment frame from the first network device. The first acknowledgement frame includes a first transmission power information element, and the first transmission power information element includes a second transmission power level. The processor updates a power control information table entry with the second transmission power level and sends a second data frame to the first network device using the second transmission power level.

A facility that controls participants in an ad hoc peer wireless network to use transmission power level settings and routing paths that best serve individual participants in the network and the network as a whole is described. Variously, the facility modulates transmission power levels to extend participant battery life and reduce the likelihood of radio interference in the network; establishes routing paths that contribute to the effectiveness and continuing operation of the network; and monitors for and responds to the occurrence of interference in the network's communications.

A method for operating a user equipment (UE) includes detecting that a first request type of a first request is not a beam failure recovery request (BFRQ) and based thereon, selecting a first random access resource for transmitting the first request, wherein the first random access resource is selected from a first subset of one or more random access resources, and wherein random access resources in the first subset are associated with a communications beam serving the UE, and transmitting, by the UE to an access node, the first request in the first random access resource.
