Systems and methods for a physical uplink control channel on a secondary cell
摘要
說明書
Yet another user equipment (UE) is described. The UE includes a processing circuitry. The processing circuitry is configured and/or programmed to receive by a Radio Resource Control (RRC) entity of the UE, a Physical Uplink Control Channel (PUCCH)/Sounding Reference Signal (SRS) release request from a lower layer of the UE, receive by the RRC entity of the UE, a PUCCH release request from a lower layer of the UE, apply a default physical channel configuration for a scheduling request configuration for all serving cells, upon receiving the PUCCH/SRS release request from the lower layer of the UE, and apply the default physical channel configuration for a scheduling request configuration for a concerned secondary cell, upon receiving the PUCCH release request from the lower layers of the UE. The default physical channel configuration for the scheduling request configuration is a release and the PUCCH release request is notified by a Medium Access Control (MAC) entity of the UE in a case that a time alignment timer expires, the time alignment timer is associated with a secondary timing advance group (sTAG) and the concerned secondary cell belongs to the sTAG.
