Abstract
Described herein are mechanismns and methods that facilitate generation of receiver status message (e.g., acknowledgments and/or negative acknowledgments) before, during, and after a handoff of an access terminal (user equipment) from a first transceiver module to a second transceiver module. A network module can generate receiver status messages during a handoff and informs a target transceiver module of when it can begin to generate receiver status messages for data received from an access terminal.
Claims58
A method of handoff for wireless communications, comprising:
- receiving a handoff indication with respect to an access terminal from a target transceiver module;
- generating a receiver status message for data received from one or more of a source transceiver module and the target transceiver module upon receipt of the indication;
- and
- ceasing to generate receiver status messages for data received from one or more of a source transceiver module and the target transceiver module upon confirmation of the handoff.
A computer-readable medium comprising computer-executable instructions for:
- generating a receiver status message for data received from an access terminal by way of one or more transceiver modules;
- instructing a target transceiver module to begin generating a receiver status message with respect to data received from the access terminal;
- and
- ceasing to generate receiver status messages.
A communications apparatus, comprising:
- a memory that comprises instructions for instructing a target transceiver module to create receiver status messages with respect to data received from an access terminal;
- and
- a processor configured to execute the instructions.
A communications apparatus, comprising:
- means for receiving data from one or more transceiver modules;
- means for receiving an indication that an access terminal is requesting a handoff from a source transceiver module to a target transceiver module;
- and
- means for instructing the target transceiver module to begin creating receiver status messages with respect to data received from the access terminal.
A processor configured to execute instructions for:
- receiving all indication that an access terminal has requested a handoff from a source transceiver module to a target transceiver module;
- and
- instructing the target transceiver module to begin locally generating receiver status messages for data received from the access terminal.
A method, comprising:
- receiving a request for a handoff with respect to an access terminal;
- receiving data from the access terminal;
- and
- generating receiver status messages upon confirmation of the handoff.
A computer-readable medium comprising computer-executable instructions for:
- receiving an indications that an access terminal has requested a handoff from a source transceiver module to a target transceiver module that comprises the computer-readable medium;
- receiving data from the access terminal over a physical channel;
- and
- locally generating receiver status messages with respect to the received data upon confirmation of the handoff.
A communications apparatus,comprising:
- a memory that comprises instructions for;
- receiving confirmation from a network module that an access terminal has been handed off from a source transceiver module to a target transceiver module;
- and
- generating receiver status messages for data received from the access terminal upon receipt of the confirmation;
- and
- a processor that is configured to execute the instructions within the memory.
A communications apparatus, comprising:
- means for receiving confirmation that an access terminal has been handed off from a source transceiver module to target transceiver module;
- means for receiving data from the access terminal;
- means for locally generating receiver status messages at the target transceiver module for the received data;
- and
- means for transmitting the receiver status messages to the access terminal.
A processor configured to execute instructions for:
- receiving data from an access terminal upon receipt of a confirmation that the access terminal has been handed off from a source transceiver module to a target transceiver module, wherein the confirmation is received from a network module, the source transceiver module and the target transceiver module reside at a network edge and the network module resides above the source transceiver module and the target transceiver module within a network hierarchy;
- and
- generating receiver status messages for the data received from the access terminal.
