Resource determination in wireless communications
The present application relates to methods, systems, and devices related to digital wireless communication, and more specifically, to techniques related to digital wireless communication, and more specifically, to techniques related to maintaining a PDCCH blind decoding budget in the case that a cell can be scheduled by another cell and by itself. In one exemplary aspect, a method for wireless communication is disclosed. The method includes receiving, by a terminal on a scheduling cell, control information for a first cell according to a rule that an amount of blind decoding resources for the first cell does not exceed a budget, wherein the first cell is scheduled by the scheduling cell and the first cell is also scheduled by itself.
1. A method for wireless communication, comprising:
receiving, by a terminal, control information for a first cell according to a rule that an amount of blind decoding resources for the first cell does not exceed a budget, wherein the budget comprises a physical downlink control channel (PDCCH) candidate budget and a non-overlapped control channel element (CCE) budget; and
counting, by the terminal, the first cell only once to determine the budget in a case that the first cell is scheduled by the scheduling cell and the first cell is also scheduled by itself.
2. The method of claim 1 , wherein the blind decoding resources include a number of candidates or non-overlapped control channel elements (CCEs) for physical downlink control channel (PDCCH) blind decoding.
3. The method of claim 1 , wherein the first cell comprises one of a primary cell (PCell), a primary secondary cell group cell (PSCell), and a secondary cell (SCell).
4. The method of claim 1 , wherein the rule further includes that a number of candidates for self-scheduling or a number of candidates for cross-carrier scheduling are separately configured for the first cell.
5. A terminal for wireless communication comprising a processor that is configured to carry out a method comprising:
receiving, by the terminal on a scheduling cell, control information for a first cell according to a rule that an amount of blind decoding resources for the first cell does not exceed a budget, wherein the first cell is scheduled by the scheduling cell and the first cell is also scheduled by itself, wherein the budget comprises a physical downlink control channel (PDCCH) candidate budget and a non-overlapped control channel element (CCE) budget; and
counting, by the terminal, the first cell only as one cell for determining the budget for scheduling the first cell from the first cell itself.
6. The terminal of claim 5 , wherein the blind decoding resources includes a number of candidates or non-overlapped control channel elements (CCEs) for physical downlink control channel (PDCCH) blind decoding.
7. The terminal of claim 5 , wherein the first cell comprises one of a primary cell (PCell), a primary secondary cell group cell (PSCell), and a secondary cell (SCell).
8. The terminal of claim 5 , wherein the rule further includes that a number of candidates for self-scheduling and a number of candidates for cross-carrier scheduling are configured for the first cell.
9. The terminal of claim 8 , wherein the number of candidates in a search space are configured for self-scheduling or cross-carrier scheduling.
10. A method for wireless communication, comprising:
providing, by a scheduling cell implemented by a base station, to a terminal, control information for a first cell according to a rule that an amount of blind decoding resources for the first cell does not exceed a budget, wherein the first cell is scheduled by the scheduling cell and the first cell is also scheduled by itself, wherein the budget comprises a physical downlink control channel (PDCCH) candidate budget and a non-overlapped control channel element (CCE) budget, wherein the first cell is counted only as one cell for determining the budget for scheduling the first cell from the first cell itself.
11. The method of claim 10 , wherein the blind decoding resources includes a number of candidates or non-overlapped control channel elements (CCEs) for physical downlink control channel (PDCCH) blind decoding.
12. The method of claim 10 , wherein the first cell comprises one of a primary cell (PCell), a primary secondary cell group cell (PSCell), and a secondary cell (SCell).
13. The method of claim 10 , wherein the rule further includes that a number of candidates for self-scheduling and a number of candidates for cross-carrier scheduling are configured for the first cell.
14. The method of claim 13 , wherein the number of candidates in a search space are configured for self-scheduling or cross-carrier scheduling.
