Transmission of mobile requests in wireless uplink system

A method for use in a wireless communications mobile unit comprising the steps of:

• transmitting an access request message on a resource dedicated to a mobile unit to a base station;
• detecting a request response message received from said base station on a prescribed downlink resource;
• and
• transmitting an acknowledgment message indicative of reception of said request response message on a prescribed shared uplink resource to said base station,
• wherein said shared downlink resource includes a number of time slots based on a number of mobile units that are sharing said shared downlink resource,
• whereby latency is reduced and reliability is improved.

A method for use in a wireless communications base station comprising the steps of:

• monitoring received request time slots to detect an incoming request from one or more mobile units on time slots, each of said time slots dedicated on a one-to-one basis to said one or more mobile units;
• determining whether any requests have been received;
• if at least one request has been received, transmitting a request response message on a shared downlink resource to said one or more requesting mobile units corresponding to said at least one request;
• and
• determining whether an acknowledgment message has been received on a shared unlink acknowledgment resource having a one-to-one correspondence i.e., slaved, to said downlink response resource on which said response message was transmitted indicating that said intended mobile unit has received said response message,
• whereby latency is reduced and reliability is improved.

A method for use in a wireless communications base station comprising the steps of:

• monitoring received request time slots to detect an incoming request from at least one mobile unit on time slot dedicated to said at least one mobile unit;
• determining whether any requests have been received;
• if at least one request has been received, transmitting a request response message on a shared downlink resource to an intended one of one or more requesting mobile units, said shared downlink resource including a number of time slots based on a number of mobile units that are sharing said shared downlink resource;
• and
• determining whether an acknowledgment message has been received indicating that said intended mobile unit has received said response message;
• whereby latency is reduced and reliability is improved.

A method for use in a wireless communications system including one or more base stations and one or more mobile units comprising the steps of:

• in a particular mobile unit,
• transmitting an access request message on a resource dedicated to said particular mobile unit to a base station, wherein no identification of the particular mobile unit need be transmitted,
• detecting a request response message received from said base station on a prescribed downlink resource shared with others of said one or more mobile units, and
• transmitting an acknowledgment message indicative of reception of said request response message on a prescribed shared uplink resource to said base station,
• wherein said prescribed shared uplink resource has a one-to-one correspondence, i.e., is slaved, to said prescribed shared downlink resource;
• and
• in a base station,
• monitoring received request time slots to detect an incoming request from one or more mobile units on time slots, each of said time slots dedicated on a one-to-one basis to said one or more mobile units,
• determining whether any requests have been received,
• if at least one request has been received, transmitting a request response message on a shared downlink resource to an intended one of one or more requesting mobile units corresponding to said at least one request,
• determining whether an acknowledgment message has been received on a shared uplink acknowledgment resource having a one-to-one correspondence, i.e., being slaved, to said downlink response resource on which said response message was transmitted indicating that said intended one mobile unit has received said response messages, and
• wherein said prescribed shared uplink resource has a one-to-one correspondence, i.e., is slaved, to said prescribed shared downlink resource,
• whereby latency is reduced and reliability is improved.

Apparatus for use in a wireless communications mobile unit comprising:

• a controllable transmitter for transmitting an access request message on a wireless uplink to a base station on a uplink resource dedicated to a particular mobile unit, wherein no identification of the particular mobile unit need be transmitted to said base station;
• a controllable receiver for detecting a received request response message on a wireless downlink from said base station on a downlink resource shared with other mobile units;
• and
• wherein said transmitter transmits an acknowledgment message indicative of reception of said request response message to said base station on a shared uplink acknowledgment resource having a one-to-one correspondence, i.e., slaved to said shared downlink response resource on which said response message was received,
• whereby latency is reduced and reliability is improved.

Apparatus for use in a wireless communications base station comprising:

• a controllable receiver for monitoring received request time slots to detect an incoming request from one or more mobile units on time slots, dedicated on a one-to-one basis to said one or more mobile units;
• a controller for determining whether any requests have been received;
• a controllable transmitter, responsive to a determination that at least one request has been received, for transmitting a request response message on a shared downlink resource to said one or more requesting mobile units corresponding to said at least one request;
• and
• said controller determining whether an acknowledgment message has been received on a shared uplink acknowledgment resource having a one-to-one correspondence, i.e., slaved, to said downlink response resource on which said response message was transmitted indicating that said intended mobile unit has received said response message on a shared uplink acknowledgment resource having a one-to-one correspondence, i.e., slaved, to said downlink response resource on which said response message was transmitted,
• whereby latency is reduced and reliability is improved.

Apparatus for use in a wireless communications system including one or more base stations and one or more mobile units comprising:

• in a particular mobile unit,
• a controllable transmitter for transmitting an access request message to a base station on a resource dedicated to said particular mobile unit, wherein no identification of the particular mobile unit need be transmitted,
• a controllable receiver for detecting a request response message received from said base station on a prescribed downlink resource shared with others of said one or more mobile units, and
• wherein said transmitter transmits an acknowledgment message indicative of reception of said request response message on a prescribed shared uplink resource to said base station;
• and
• in a base station,
• a controllable receiver for monitoring received request time slots to detect an incoming request from one or more mobile units on time slots, each of said time slots dedicated on a one-to-one basis to said one or more mobile units,
• a controller for determining whether any requests have been received;
• a controllable transmitter responsive to a determination that at least one request has been received, for transmitting a request response message on a shared downlink resource to an intended one of one or more requesting mobile units corresponding to said at least one request, and
• said controller determining whether an acknowledgment message has been received on a shared uplink acknowledgment resource having a one-to-one correspondence i.e., being slaved, to said downlink response resource on which said response message was transmitted indicating that said intended one mobile unit has received said response message,
• wherein said prescribed shared uplink resource has a one-to-one correspondence, i.e., is slaved, to said prescribed shared downlink resource,
• whereby latency is reduced and reliability is improved.
