Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may transmit a first transmission using a first resource, and transmit a retransmission of the first transmission using a second resource, wherein the second resource is configured from a plurality of second resources based at least in part on an interference muting configuration of the wireless communication device. Numerous other aspects are provided.
Claims30
A method of wireless communication performed by a user equipment (UE), comprising:
- receiving information identifying a set of parameters of a base station,
- wherein the set of parameters is for a retransmission of a first transmission by the base station,
- wherein the set of parameters define a set of hypotheses for blind decoding to receive the retransmission and include information identifying an assigned resource for the retransmission, and
- wherein a size of the assigned resource is determined based at least in part on:
- a total size of resources used for the first transmission, the assigned resource, and muted resources,
- a muting factor, and
- a ratio of a size of the resources used for the first transmission to the total size,
- wherein the ratio is based at least in part on a target packet error rate, the muting factor, a first block error rate associated with the first transmission, and a second block error rate associated with the retransmission;
- and
- receiving the retransmission using the assigned resource by performing blind decoding based at least in part on the set of parameters.

A method of wireless communication performed by a base station, comprising:
- transmitting a first transmission using a first resource,
- wherein interference muting is not performed for the first resource;
- and
- transmitting a retransmission of the first transmission using a second resource,
- wherein the second resource is configured from a plurality of second resources based at least in part on an interference muting configuration of the base station, and
- wherein a size of the second resource is determined based at least in part on:
- a total size of resources used for the first transmission, the second resource, and muted resources,
- a muting factor, and
- a ratio of a size of the resources used for the first transmission to the total size,
- wherein the ratio is based at least in part on a target packet error rate, the muting factor, a first block error rate associated with the first transmission, and a second block error rate associated with the retransmission.
7 more elements
A user equipment (UE) for wireless communication, comprising:
- a memory;
- and
- one or more processors operatively coupled to the memory, the memory and the one or more processors to:
- receive information identifying a set of parameters of a base station,
- wherein the set of parameters is for a retransmission of a first transmission by the base station,
- wherein the set of parameters define a set of hypotheses for blind decoding to receive the retransmission and include information identifying an assigned resource for the retransmission, and
- wherein a size of the assigned resource is determined based at least in part on:
- a total size of resources used for the first transmission, the assigned resource, and muted resources,
- a muting factor, and
- a ratio of a size of the resources used for the first transmission to the total size,
- wherein the ratio is based at least in part on a target packet error rate, the muting factor, a first block error rate associated with the first transmission, and a second block error rate associated with the retransmission;
- and
- receive the retransmission using the assigned resource by performing blind decoding based at least in part on the set of parameters.
10 more elements
A non-transitory computer-readable medium storing one or more instructions for wireless communication, the one or more instructions comprising:
- one or more instructions that, when executed by one or more processors of a user equipment (UE), cause the one or more processors to:
- receive information identifying a set of parameters of a base station,
- wherein the set of parameters is for a retransmission of a first transmission by the base station,
- wherein the set of parameters define a set of hypotheses for blind decoding to receive the retransmission and include information identifying an assigned resource for the retransmission, and
- wherein a size of the assigned resource is determined based at least in part on:
- a total size of resources used for the first transmission, the assigned resource, and muted resources,
- a muting factor, and
- a ratio of a size of the resources used for the first transmission to the total size,
- wherein the ratio is based at least in part on a target packet error rate, the muting factor, a first block error rate associated with the first transmission, and a second block error rate associated with the retransmission;
- and
- receive the retransmission by performing blind decoding based at least in part on the set of parameters.
