Abstract
A communication device (100) receives a first portion of an information packet via a primary communication resource (102). During a time period otherwise allocated for receiving a second portion of the information packet, the communication device (100) determines the signal quality of one or more other communication resources. The communication device then requests retransmission of the second portion of the information packet.
Claims14
A method for a communication device to determine a signal quality of a group of communication resources during a conveyance of an information packet in a communication system, the method comprising steps of:
- receiving a first portion of the information packet via a communication resource;
- determining the signal quality of the group of communication resources during a time period otherwise allocated for receiving a second portion of the information packet wherein the group of communication resources does not include the communication resource;
- and
- requesting retransmission of the second portion of the information packet, further comprising the step of determining whether to measure the signal quality of the group of communication resources prior to the step of determining the signal quality of the group of communication resources, wherein the step of receiving comprises the step of receiving the first portion of the information packet via the communication resource;
- wherein the information packet was transmitted at a modulation rate;
- and wherein the step of determining whether to measure the signal quality of the group of communication resources comprises the step of determining whether the second portion of the information packet will be retransmitted at the modulation rate.

- determining the signal quality of the group of communication resources during a time period otherwise allocated for receiving a second portion of the information packet, wherein the group of communication resources does not include the communication resource;
- and
- requesting retransmission of the second portion of the information packet, further comprising the step of determining whether to measure the signal quality of the group of communication resources prior to the step of determining the signal quality of the group of communication resources, wherein the step of determining whether to measure the signal quality of the group of communication resources comprises the step of determining whether a difference between a rate of neighbor cell signal quality measurement and a target rate of neighbor cell signal quality measurement is greater than or equal to a threshold.

A method for a communication device to determine a signal quality of a group of communication resources during a conveyance of an information packet in a communication system, the method comprising steps of:
- receiving a first portion of the information packet via a communication resource;
- determining the signal quality of the group of communication resources during a time period otherwise allocated for receiving a second portion of the information packet, wherein the group of communication resources does not include the communication resource;

- requesting retransmission of the second portion of the information packet, further comprising the step of determining whether to measure the signal quality of the group of communication resources prior to the step of determining the signal quality of the group of communication resources, wherein the step of determining whether to measure the signal quality of the group of communication resources comprises the step of determining whether a signal quality of the communication resource is less than or equal to a quality threshold.
A communication device comprising:
- a receiver that receives a first portion of an information packet via a communication resource;
- a processor, coupled to the receiver, that instructs the receiver to determine a signal quality of a group of communication resources during a time period otherwise allocated for receiving a second portion of the information packet, wherein the group of communication resources does not include the communication resource, that determines whether to measure the signal quality of the group of communication resources prior to determining the signal quality of the group of communication resources, wherein the information packet was transmitted at a modulation rate, and wherein determining whether to measure the signal quality of the group of communication resources comprises determining whether the second portion of the information packet will be retransmitted at the modulation rate;
- and
- a transmitter, coupled to the processor, that transmits, when instructed by the processor, a request for retransmission of the second portion of the information packet.
