Abstract
An apparatus and an associated method selects rates at which received signals are sampled in a multi-user communication system. The signals are sampled at initial sampling rates during a first period. An estimate is made of the number of received signals, and selection is made of an updated sampling rate, based in part upon the estimate.
Claims20
A method for operating upon a received signal, said method comprising:
- sampling the received signal at an initial sampling rate;
- estimating a number of wireless-device transmissions from the received signal;
- and
- commanding at least one of:
- changing the initial sampling rate to an updated sampling rate, and
- a user equipment transmission adjustment to avoid an error-floor condition due to operating outside of a rate-region of a multiple access system.
A method for facilitating communication by a wireless device, said method comprising;
- receiving at the wireless device a network-oriainated indication of a power level at which messages are to be received at the network;
- estimating a number of wireless-device transmissions from the received signal;
- adjustng a condititonal transmit power level of the wireless device in response to said indication;
- and
- transmitting, at the conditional transmit leve, data formatted into pilot signals and words.
An apparatus for wireless communications, said apparatus comprising:
- a processor configured to:
- sample the received signal at an initial sampling rate;
- estimate a number of wireless-device transmissions from the received signal;
- and
- command at least one of:
- changing the initial sampling rate to an updated sampling rate, and
- a user equipment transmission adjustment to avoid an error-floor condition due to operating outside of a rate-region of a multiple access system.
A non-transitory computer readable medium storing a program causing a computer to execute wireless communication, said method comprising:
- sampling the received signal at an initial sampling rate;
- estimating a number of wireless-device transmissions from the received signal;
- and
- commanding at least one of:
- changing the initial sampling rate to an updated sampling rate, and
- a user equipment transmission adjustment to avoid an error-floor condition due to operating outside of a rate-region of a multiple access system.
