Abstract:
Methods and systems for dynamically activate and deactivate an allocated resource for a UE to make grant-free uplink transmission are provided. In one embodiment, a user equipment (UE) receives a Radio Resource Control (RRC) signal. The RRC signal specifies grant-free (GF) configuration information. The GF configuration information comprises an activation field and at least one other GF resource configuration field. The activation field indicates whether the UE may perform GF uplink (UL) transmissions without waiting for a downlink control information (DCI) message. Then, the UE performs a GF UL transmission in accordance with the GF configuration information in the RRC signal.
Abstract:
The application provides manner for communicating channel state information (CSI) in a communication network. A preset length is used for equalizing lengths of CSI to be reported. The preset length is determined based on a quantity of CSI-reference signal (RS) ports. A communication device determines whether a total length of one or more indication information items to be included in the CSI is less than the preset length. If the total length of the one or more indication information items to be included in the CSI is less than the preset length, the communication device adds one or more padding bits, to obtain a CSI bit sequence including the one or more indication information items and the one or more padding bits. A total length of the CSI bit sequence is consistent with the preset length. The communication device then outputs the CSI bit sequence.
