Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may extract information from a neighboring base station with cell coverage that overlaps cell coverage of the base station. The base station may determine, from the information, one or more locations of control resource sets (CORESETs) used by the neighboring base station. The base station may select resources that do not overlap with the CORESETs used by the neighboring base station. The base station may transmit a communication using the selected resources. Numerous other aspects are described.
Claims28
A network device for wireless communication, comprising:
- memory;
- and
- one or more processors coupled to the memory, the memory including instructions executable by the one or more processors to cause the network device to:
- extract information from a neighboring network device with cell coverage that overlaps cell coverage of the network device, wherein the information includes one or more of a physical downlink control channel (PDCCH) demodulation reference signal (DMRS) scrambling identifier (ID), a resource block allocation, a slot, or symbols used by the neighboring network device in a PDCCH common configuration;
- determine, from the information, one or more locations of control resource sets (CORESETs) used by the neighboring network device;
- select resources that do not overlap with the CORESETs used by the neighboring network device, wherein the resources comprise one or more of a PDCCH DMRS scrambling ID, a resource block allocation, a slot, or symbols that are different than the one or more of the PDCCH DMRS scrambling ID, the resource block allocation, the slot, or the symbols used by the neighboring network device;
- and
- transmit a communication using the selected resources.
A method of wireless communication performed by a network device, comprising:
- extracting information from a neighboring network device with cell coverage that overlaps cell coverage of the network device, wherein the information includes one or more of a physical downlink control channel (PDCCH) demodulation reference signal (DMRS) scrambling identifier (ID), a resource block allocation, a slot, or symbols used by the neighboring network device in a PDCCH common configuration;
- determining, from the information, one or more locations of control resource sets (CORESETs) used by the neighboring network device;
- selecting resources that do not overlap with the CORESETs used by the neighboring network device, wherein the resources comprise one or more of a PDCCH DMRS scrambling ID, a resource block allocation, a slot, or symbols that are different than the one or more of the PDCCH DMRS scrambling ID, the resource block allocation, the slot, or the symbols used by the neighboring network device;
- and
- transmitting a communication using the selected resources.
A non-transitory computer-readable medium storing one or more instructions for wireless communication, the one or more instructions, when executed by one or more processors of a network device, cause the network device to:
- extract information from a neighboring network device with cell coverage that overlaps cell coverage of the network device, wherein the information includes one or more of a physical downlink control channel (PDCCH) demodulation reference signal (DMRS) scrambling identifier (ID), a resource block allocation, a slot, or symbols used by the neighboring network device in a PDCCH common configuration;
- determine, from the information, one or more locations of control resource sets (CORESETs) used by the neighboring network device;
- select resources that do not overlap with the CORESETs used by the neighboring network device, wherein the resources comprise one or more of a PDCCH DMRS scrambling ID, a resource block allocation, a slot, or symbols that are different than the one or more of the PDCCH DMRS scrambling ID, the resource block allocation, the slot, or the symbols used by the neighboring network device;
- and
- transmit a communication using the selected resources.
An apparatus for wireless communication, comprising:
- means for extracting information from a neighboring network device with cell coverage that overlaps cell coverage of a network device, wherein the information includes one or more of a physical downlink control channel (PDCCH) demodulation reference signal (DMRS) scrambling identifier (ID), a resource block allocation, a slot, or symbols used by the neighboring network device in a PDCCH common configuration;
- means for determining, from the information, one or more locations of control resource sets (CORESETs) used by the neighboring network device;
- means for selecting resources that do not overlap with the CORESETs used by the neighboring network device, wherein the resources comprise one or more of a PDCCH DMRS scrambling ID, a resource block allocation, a slot, or symbols that are different than the one or more of the PDCCH DMRS scrambling ID, the resource block allocation, the slot, or the symbols used by the neighboring network device;
- and
- means for transmitting a communication using the selected resources.
