Abstract: Methods and apparatuses are provided for monitoring a physical downlink control channel (PDCCH). A user equipment (UE) reports capability information indicating one or more tuples. Each tuple indicates a combination of serving cells configured for per-slot and per-span monitoring that the UE is capable of supporting. An indication is received in response to the capability information. A pair of values is determined based on the indication. A first value is a maximum number of serving cells configured for per-slot monitoring, and a second value is a maximum number of serving cells configured for per-span monitoring. A monitored candidate limit per slot is determined based on the first value. A monitored candidate limit per span is determined based on the second value.

Abstract: A method, user equipment (UE), and terminal are disclosed, the method includes receiving a first physical downlink shared channel (PDSCH), receiving a second PDSCH that overlaps in time with the first PDSCH, determining a delay in processing time for a hybrid automatic repeat request (HARD)-acknowledgement (ACK) corresponding to the second PDSCH based on the overlapping time between the first PDSCH and the second PDSCH, and transmitting the HARQ-ACK corresponding to the second PDSCH.

Abstract: A method for random access in a wireless communication network may include selecting a first configuration or a second configuration for a physical uplink shared channel (PUSCH), selecting a preamble from a first preamble group corresponding to the first configuration or a second preamble group corresponding to the second configuration, transmitting the selected preamble from a user equipment (UE) through a physical random access channel (PRACH), and transmitting a payload from the UE through the PUSCH using the selected configuration, wherein the selected configuration and the selected preamble may be determined by the UE. The one or more preambles in the first and second preamble groups may be mapped to one or more sets of PUSCH resources in the first and second configurations, respectively, and the UE may transmit the payload using the set of PUSCH resources mapped to the selected preamble.
