The apparatus may implement a hybrid per flow/connection and per station uplink (UL) resource allocation to improve UL control efficiency and UL resource utilization. The apparatus may be configured to transmit or receive a resource allocation in a signal that contains an indicator that indicates intended flow information. ## Claims ### Claim 1 A wireless transmit/receive unit (WTRU) comprising: circuitry configured to transmit uplink data using at least one selected connection of a plurality of connections; circuitry further configured to receive a medium access control (MAC) control message which indicates at least one of the plurality of connections are active for use in the transmission of the uplink data, wherein the circuitry is further configured to receive control information indicating an allocation of uplink resources for transmission of the uplink data on a first one of the connections that is active, wherein the control information includes a field indicating the first one connection of the plurality of connections, and wherein the field is at least two bits; and circuitry further configured to transmit the uplink data using at least one of the plurality of connections that is active. ### Claim 2 (depends on 1) The WTRU of claim 1, wherein the plurality of connections are IEEE 802.16 connections. ### Claim 3 (depends on 1) The WTRU of claim 1, wherein the allocation of uplink resources is for a single uplink transmission. ### Claim 4 (depends on 1) The WTRU of claim 1, wherein the allocation of uplink resources is for a persistent allocation. ### Claim 5 (depends on 1) The WTRU of claim 1, wherein the received control information indicates a connection to be used for transmission of the uplink data. ### Claim 6 A method of transmitting uplink data from a wireless transmit/receive unit (WTRU) comprising: transmitting uplink data using at least one selected connection of a plurality of connections; receiving a medium access control (MAC) control message which indicates at least one of the plurality of connections are active for use in the transmission of the uplink data; transmitting the uplink data using at least one of the plurality of connections that is active; and receiving control information indicating an allocation of uplink resources for transmission of the uplink data on a first one of the connections that is active, wherein the control information includes a field indicating the first one connection of the plurality of connections, and wherein the field is at least two bits. ### Claim 7 (depends on 6) The method of claim 6, wherein the plurality of connections are IEEE 802.16 connections. ### Claim 8 (depends on 6) The method of claim 6, wherein the allocation of uplink resources is for a single uplink transmission. ### Claim 9 (depends on 6) The method of claim 6, wherein the allocation of uplink resources is for a persistent allocation. ### Claim 10 (depends on 6) The method of claim 6, wherein the received control information indicates a connection to be used for transmission of the uplink data. ### Claim 11 A base station comprising: circuitry configured to receive uplink data over at least one of a plurality of connections; circuitry configured to transmit a medium access control (MAC) control message which indicates at least one of the plurality of connections are active for use in transmission of the uplink data, wherein the circuitry is further configured to transmit control information indicating an allocation of uplink resources for transmission of the uplink data on a first one of the connections that is active, wherein the control information includes a field indicating the first one connection of the plurality of connections, and wherein the field is at least two bits; and circuitry configured to receive the uplink data over at least one of the plurality of connections that is active. ### Claim 12 (depends on 11) The base station of claim 11, wherein the plurality of connections are IEEE 802.16 connections. ### Claim 13 (depends on 11) The base station of claim 11, wherein the allocation of uplink resources is for a single uplink transmission. ### Claim 14 (depends on 11) The base station of claim 11, wherein the allocation of uplink resources is for a persistent allocation. ### Claim 15 (depends on 11) The base station of claim 11, wherein the transmitted control information indicates a connection to be used for transmission of the uplink data.
