Abstract
Embodiments include a physical resource block scheduling method, network device, and system, which may be used to perform scheduling request indicator SRI scheduling. The method includes: receiving a scheduling request indicator SRI sent by user equipment UE; allocating M PRBs to the UE according to a reference quantity of bits for scheduling; receiving, on a physical uplink shared channel, an uplink transmission block TB that is sent, in response to current-time SRI scheduling, by the UE; and determining, according to the uplink TB, a reference quantity of bits for scheduling for next-time SRI scheduling of the UE.
Claims17
A method, comprising:
- receiving, by a network device, a scheduling request indicator (SRI) sent by user equipment (UE), wherein the SRI is used for the UE to request transmission of to-be-transmitted uplink data;
- allocating, by the network device, M physical resource blocks (PRBs) to the UE according to a reference quantity of bits for scheduling, wherein M is an integer greater than or equal to zero, the reference quantity of bits for scheduling is set by the network device, and the reference quantity of bits for scheduling is less than or equal to a total quantity of bits that can be transmitted by using the M PRBs;
- receiving, by the network device, on a physical uplink shared channel (PUSCH), an uplink transmission block (TB) that is sent, in response to SRI scheduling, by the UE using at least one PRB of the M PRBs;
- and
- determining, by the network device according to the uplink TB, a reference quantity of bits for scheduling for next-time SRI scheduling of the UE.
