Description

Channel resource scheduling method and base station based on terminal capability reporting
Technical Field
The embodiment of the invention relates to the technical field of communication, in particular to a channel resource scheduling method and a base station based on terminal capability reporting.
Background
Broadband Trunking Communication (B-TrunC) is a time division long term evolution TD-LTE based private network broadband Trunking system standard established by the broadband Trunking industry alliance organization.
The standard describes a blind detection capability type 1 terminal and a blind detection capability type 2 terminal, wherein for a blind detection capability type 2 terminal, and/or a terminal which does not support the simultaneous reception of the physical layer shared channel PDSCH data scrambled by the cell radio network temporary identifier C-RNTI and the PDSCH data scrambled by the group radio network temporary identifier G-RNTI in a downlink transmission time interval TTI, the standard specifies that the terminal capability needs to be reported to the base station, after the base station receives the reported terminal capability, if the terminal is in the RRC connection state, the scheduling time of the PDSCH data scrambled by the C-RNTI of the cell where the terminal is located and the scheduling time of the PDSCH data scrambled by the G-RNTI of the group where the terminal is located on the PDSCH are staggered, and scheduling PDCCH resources of a group corresponding to the terminal in a physical layer control channel PDCCH public space, otherwise scheduling the PDCCH resources in the PDCCH public space and a group dedicated space.
However, the signaling used by the existing standard only carries the G-RNTI of the group where the terminal is located when reporting the terminal capability, and the base station cannot distinguish the blind detection capability type of the terminal and whether the terminal supports simultaneous reception of the PDSCH data scrambled by the C-RNTI and the PDSCH data scrambled by the G-RNTI in one downlink TTI according to the reported terminal capability, so that when the terminal is in a connected state and reports the terminal capability, the base station cannot distinguish the blind detection capability of the terminal and whether the terminal supports simultaneous reception of the PDSCH data scrambled by the C-RNTI and the PDSCH data scrambled by the G-RNTI in one downlink TTI, only can consider the terminal reporting the terminal capability as having a blind detection capability of 2 and does not support simultaneous reception of the PDSCH data scrambled by the C-RNTI and the PDSCH data scrambled by the G-RNTI in one downlink TTI, and the base station can only schedule the PDCCH resource of the group where the terminal is located in the PDCCH common space, the resource capacity of the PDCCH is reduced, and for a PDSCH channel, for C-RNTI unicast service and G-RNTI multicast service, the base station needs to stagger scheduling resources in the time domain, and the throughput of the PDSCH unicast and multicast service can be influenced.
