Abstract

The technology described herein is directed towards puncturing physical downlink shared channel (PDSCH) data in a defined slot symbol, otherwise reserved for CORESET (control resource set) information, with physical downlink control channel (PDCCH) information. A scheduler schedules PDSCH data into the otherwise defined/reserved symbol. Network equipment (e.g., a gNodeB) then overwrites at least some of the PDSCH data in that symbol with the PDCCH information, resulting in punctured PDSCH data in that symbol. For transmitting, the coding rate/repetition pattern is adjusted by the network equipment such that a receiving user equipment is able to recover the overwritten PDSCH data during decoding. As a result, an entire symbol otherwise used only for PDCCH information is able to be used for PDSCH data.

1 . Network equipment, comprising:

at least one processor; and

at least one memory that stores executable instructions that, when executed by the at least one processor, facilitate performance of operations, the operations comprising:

3 . The network equipment of claim 1 , wherein the defined downlink control information control resource set is within a first symbol of the slot data.

4 . The network equipment of claim 1 , wherein the operations further comprise, prior to the overwriting of the physical downlink shared channel data, scheduled within the defined control resource set, scheduling the physical downlink control channel information within the defined symbol of the slot data.

5 . The network equipment of claim 1 , wherein the overwriting of the physical downlink shared channel data is performed by a gNodeB.

6 . The network equipment of claim 1 , wherein the operations further comprise;

determining a coding rate that is able to be used to increase a likelihood that the user equipment receives sufficient data according to a defined sufficiency criterion, and wherein the coding rate corresponds to the transmitting of the slot data, to recover the punctured scheduled physical downlink shared channel data.

7 . The network equipment of claim 1 , wherein the operations further comprise:

8 . The network equipment of claim 1 , wherein the user equipment is a first user equipment, wherein the overwriting of the physical downlink shared channel data comprises overwriting with first physical downlink control channel information for the first user equipment and overwriting with second physical downlink control channel information for a second user equipment, and wherein the transmitting of the slot data comprises transmitting the slot data to the first user equipment and to the second user equipment.

9 . A method, comprising:

scheduling, by a system comprising at least one processor, physical downlink shared channel data within a slot, comprising mapping the physical downlink shared channel data for a user equipment to symbol locations within the slot, the symbol locations corresponding to specified control resource set and comprising a specified control resource set symbol location reserved for physical downlink control channel information;

overwriting, by the system, the physical downlink shared channel data within the specified control resource set symbol location, with physical downlink control channel data, resulting in physical downlink shared channel data punctured with physical downlink control channel data that maps the user equipment to the symbol locations within the slot, resulting in punctured physical downlink shared channel data;

transmitting, by the system, the slot to the user equipment with a redundancy pattern via which the user equipment is able to recover the punctured physical downlink shared channel data that was punctured with the physical downlink control channel data; and

determining a repetition pattern corresponding to the redundancy pattern usable to increase a likelihood that the user equipment is able to receive at least a threshold amount of data, corresponding to the transmitting of the slot, to recover the punctured physical downlink shared channel data.

10 . The method of claim 9 , wherein the overwriting of the physical downlink shared channel data within the specified control resource set symbol location comprises overwriting a first subgroup of a larger group of locations in the specified control resource set, and not overwriting a second subgroup, of the larger group of locations in a specified symbol, that comprises a portion of the physical downlink shared channel data.

11 . The method of claim 9 , further comprising:

determining, by the system, a coding rate corresponding to the redundancy pattern and usable to increase a likelihood that at least one of the first user equipment is able to receive at least the threshold amount of data, corresponding to the transmitting of the slot, to recover the punctured physical downlink shared channel data.

12 . The method of claim 10 , wherein the overwriting of the physical downlink shared channel data within the specified control resource set location is performed by gNodeB equipment.

13 . The method of claim 9 , wherein the user equipment comprises a first user equipment, wherein the scheduling comprises scheduling of first physical downlink shared channel data, of the physical downlink shared channel data, within the slot, and wherein the overwriting comprises overwriting the first the physical downlink shared channel data with first physical downlink control channel data, of the physical downlink control channel data, and
