Abstract
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a downlink transmission via at least one of a primary cell, a secondary cell, or a combination thereof. The UE may identify a feedback indication for the downlink transmission. The UE may transmit a first feedback message that includes the feedback indication via the primary cell. The UE may transmit a second feedback message that also includes the feedback indication via the secondary cell.
Claims28
A method for wireless communication at a user equipment (LTE), comprising:
- receiving downlink signaling via at least one of a primary cell, a secondary cell, or a combination thereof;
- identifying a message configured via the downlink signaling, a feedback indication for the downlink signaling, or both;
- transmitting, via the primary cell and based at least, in part on the downlink signaling, a first uplink control channel message comprising a first payload;
- and
- transmitting, via the secondary cell and based at least in part on the downlink signaling, the first uplink control channel message, or both, a second uplink control channel message comprising a second payload different from the first payload, wherein the second uplink control channel message comprises the message configured via the downlink signaling or includes the feedback indication for the downlink signaling,
- wherein the first uplink control channel message comprises a first quantity of symbols, and wherein the second uplink control channel message comprises a second quantity of symbols different from the first quantity of symbols.
3 more elements
The method of claim I, further comprising:
- receiving an indication of a first uplink control channel resource configuration associated with the primary cell, wherein the first uplink control channel message is transmitted in accordance with the first uplink control channel resource configuration;
- and
- receiving an indication of a second uplink control channel resource configuration associated with the primary cell, the second uplink control channel resource configuration different from the first uplink control channel resource configuration, wherein the second uplink control channel message is transmitted in accordance with the second uplink control channel resource configuration.
A method for wireless communication at a base station, comprising:
- transmitting, to a user equipment (LIE), downlink signaling via at least one of a primary cell, a secondary cell, or a combination thereof
- receiving, via the primary cell and based at least in part on the downlink signaling, a first uplink control channel message comprising a first payload;
- and
- receiving, via the secondary cell and based at least in part on the downlink signaling, the first uplink control channel message, or both, a second uplink control channel message comprising a second payload different from the first payload, wherein the second uplink control channel message comprises a message configured via the downlink signaling or includes a feedback indication for the downlink signaling,
- wherein the first uplink control channel message comprises a first quantity of symbols, and wherein the second uplink control channel message comprises a second quantity of symbols different from the first quantity of symbols.
2 more elements
An apparatus, comprising:
- a processor;
- and
- memory, coupled with the processor, for storing
- instructions executable by the processor to:
- receive downlink signaling via at least one of a primary cell, a secondary cell, or a combination thereof;
- identify a message configured via the downlink signaling, a feedback indication for the downlink signaling, or both;
- transmit, via the primary cell and based at least in part on the downlink signaling, a first uplink control channel message comprising a first payload;
- and
- transmit, via the secondary cell and based at least in part on the downlink signaling, the first uplink control channel message, or both, a second uplink control channel message comprising a second payload different from the first payload, wherein the second uplink control channel message comprises the message configured via the downlink signaling or includes the feedback indication for the downlink signaling,
- wherein the first uplink control channel message comprises a first quantity of symbols, and wherein the second uplink control channel message comprises a second quantity of symbols different from the first quantity of symbols.
