Efficient communication between terminal and base station apparatus
A recently granted patent (Publication Number: US11778603B2) describes a terminal apparatus and a base station apparatus for efficient resource allocation in wireless communication systems. The patent also discloses communication methods for both the terminal apparatus and the base station apparatus.
The terminal apparatus includes a reception unit that receives Radio Resource Control (RRC) messages, including first and second configuration information, and downlink control information (DCI) on a physical downlink control channel (PDCCH). A determining unit in the terminal apparatus determines the time domain resource allocation for transmitting a physical uplink shared channel (PUSCH) based on a bit sequence indicated by a first field of the DCI and a resource allocation table. The resource allocation table defines the correspondence between the bit sequence and the time domain resource allocation. The terminal apparatus then transmits the PUSCH based on the determined time domain resource allocation. The resource allocation table is defined differently depending on the format of the received DCI and the presence of certain parameter lists in the configuration information.
Similarly, the base station apparatus includes a transmission unit that transmits RRC messages, including first and second configuration information, and DCI on a PDCCH. A determination unit in the base station apparatus determines the bit sequence indicated by a first field of the DCI based on the time domain resource allocation for receiving the PUSCH and a resource allocation table. The base station apparatus also includes a reception unit that receives the PUSCH based on the determined time domain resource allocation. The resource allocation table in the base station apparatus is defined in a similar manner as in the terminal apparatus, based on the format of the transmitted DCI and the presence of certain parameter lists in the configuration information.
The communication methods for both the terminal apparatus and the base station apparatus involve receiving RRC messages, including first and second configuration information, and DCI on a PDCCH. The methods also include determining the time domain resource allocation for transmitting the PUSCH based on the bit sequence indicated by a first field of the DCI and a resource allocation table. The PUSCH is then transmitted based on the determined time domain resource allocation. The resource allocation table is defined differently depending on the format of the received DCI and the presence of certain parameter lists in the configuration information.
Overall, this patent presents a novel approach to resource allocation in wireless communication systems, providing efficient transmission and reception of data between terminal apparatus and base station apparatus.
