Abstract
Interference cancellation occurs for devices, where the source of the interference is another UE. The victim UE receiver identifies subframes vulnerable to potential interference from other UEs. Candidate resource blocks in the identified vulnerable subframes are listed. Interference is cancelled for edge resource blocks and valid contiguous resource blocks.
Claims22
A method of wireless communication, comprising:
- identifying, at a user equipment (UE), system information from a neighboring cell to identify a time domain resource allocation of the neighboring cell, in which the UE is served by a serving cell that is different from the neighboring cell;
- identifying, at the UE, at least one candidate resource potentially interfered with based on a comparison of the time domain resource allocation of the neighboring cell and a time domain resource allocation of the serving cell;
- identifying, at the UE, at least one interfered resource from the at least one candidate resource by detecting uplink interference from at least one uplink resource of the neighboring cell on the at least one candidate resource based at least in part on an interference detection criteria;
- and
- performing, at the UE, interference cancellation on the at least one uplink resource.
2 more elements
A user equipment (UE) configured for wireless communication, comprising:
- a memory;
- and
- at least one processor coupled to the memory, the at least one processor being configured:
- to identify system information from a neighboring cell to identify a time domain resource allocation of the neighboring cell, in which the UE is served by a serving cell that is different from the neighboring cell;
- to identify at least one candidate resource potentially interfered with based on a comparison of the time domain resource allocation of the neighboring cell and a time domain resource allocation of the serving cell;
- to identify at least one resource from the at least one candidate resource by detecting uplink interference from at least one uplink resource of the neighboring cell on the at least one candidate resource based at least in part on an interference detection criteria;
- and
- to perform interference cancellation on the at least one uplink resource.
5 more elements
A computer program product for wireless communication in a wireless network, comprising:
- a non-transitory computer-readable medium having non-transitory program code recorded thereon, the program code comprising:
- program code to identify, at a user equipment (UE), system information from a neighboring cell to identify a time domain resource allocation of the neighboring cell, in which the UE is served by a serving cell that is different from the neighboring cell;
- program code to identify, at the UE, at least one candidate resource potentially interfered with based on a comparison of the time domain resource allocation of the neighboring cell and a time domain resource allocation of the serving cell;
- program code to identify, at the UE, at least one resource from the at least one candidate resource by detecting uplink interference from at least one uplink resource of the neighboring cell on the at least one candidate resource based at least in part on an interference detection criteria;
- and
- program code to perform, at the UE, interference cancellation on the at least one uplink resource.
