Abstract:
Provided are a time domain resource allocation method and apparatus. The method includes the following operations. A terminal acquires at least one of first information including search space configuration information, control resource set (CORESET) configuration information, and a bandwidth part type. A PDSCH time domain resource allocation table is subsequently determined according to the first information and a multiplexing pattern between a synchronization signal/physical broadcast channel block (SSB) and a CORESET.

Abstract:
A method for configuring a physical resource block of a user equipment search space includes: a system side configuring a Physical Resource Block (PRB) pair of a default User equipment specific Search Space (USS), and notifying the user equipment of positions of the PRB pairs of the default USS, or the system side agreeing with the user equipment on the positions of the PRB pairs of the default USS. The user equipment obtains the positions of the PRB pairs of the default USS according to the notification from the system side, or agrees with the system side on the positions of the PRB pairs of the default USS. The embodiments of the present document further provide the system side and the user equipment.
Abstract:
The disclosure provides an information transmission method and apparatus. The method includes: carrying a first parameter in physical layer signaling corresponding to a Physical Downlink Shared Channel (PDSCH); and transmitting, according to an indication of the first parameter, a Hybrid Automatic Repeat Request Acknowledgment (HARQ-ACK) corresponding to the PDSCH, which may be specifically identifying an indication meaning of the current first parameter on a predetermined basis and selecting which positions are used to transmit the HARQ-ACK. By adopting the above solution, a first communication node itself sets a position at which an HARQ-ACK is transmitted, and a second communication node feeds back, according to an indication, the HARQ-ACK corresponding to a PDSCH in time, thereby solving the problem of greater delay for HARQ-ACK feedback in the related art, and ensuring the low delay processing of a service.
