Acknowledging communication in a wireless network
A wireless network buffers and sends segments of transfer communication protocol (TCP) data to a user equipment (UE). The wireless network may count a number of the sent segments of the TCP data for allocation of uplink resources. The UE sends an uplink segment over the allocated uplink resources, which may include information indicating acknowledgment of receipt of the sent segments of TCP data.
1. A wireless network comprising:
a circuit located in the wireless network, wherein the circuit buffers segments of transfer communication protocol (TCP) data for downlink (DL) transmission;
a transmitter arranged to transmit the buffered segments of TCP data to a user equipment (UE);
the circuit is further configured to count a number of transmitted segments of TCP data;
wherein the circuit is further configured, in response to the count exceeding a predetermined number, to transmit a message that indicates an allocation of uplink resources to transfer an uplink segment and the allocation of uplink resources is sufficient to have information indicating acknowledgment; and
wherein the circuit is further configured to receive, in response to the uplink resources, the uplink segment which includes the information indicating acknowledgment of receipt of the transmitted segments of TCP data.
2. The wireless network of claim 1 wherein the allocation of uplink resources are resources of a shared channel.
3. The wireless network of claim 1 wherein the circuit is further configured to transmit an allocation of downlink resources and an allocation of uplink resources at a substantially a same time and wherein the allocation of uplink resources is at a time interval delayed with respect to the allocation of downlink resources.
4. The wireless network of claim 1 wherein the information indicating acknowledgement of receipt of the transmitted segments of TCP data is a stand-alone acknowledgement.
5. The wireless network of claim 1 wherein other data is received with the uplink segment.
6. The wireless network of claim 1 wherein at least one of the circuit or the transmitter is included in at least one of a base station, Node-B, or radio network controller (RNC).
7. A method performed by a network, the method comprising:
buffering, by the network, segments of transfer communication protocol (TCP) data for downlink (DL) transmission;
transmitting, by the network, the buffered segments of TCP data to a user equipment (UE);
counting, by the network, a number of transmitted segments of TCP data;
transmitting, in response to the count exceeding a predetermined number, a message that indicates an allocation of uplink resources to transfer an uplink segment and the allocation of uplink resources is sufficient to have information indicating acknowledgment; and
receiving, in response to the uplink resources, the uplink segment which includes the information indicating acknowledgment of receipt of the transmitted segments of TCP data.
8. The method of claim 7 wherein the allocation of uplink resources are resources of a shared channel.
9. The method of claim 7 wherein further comprising:
transmitting, by the network, an allocation of downlink resources and an allocation of uplink resources at a substantially a same time and wherein the allocation of uplink resources is at a time interval delayed with respect to the allocation of downlink resources.
10. The method of claim 7 wherein the information indicating acknowledgement of receipt of the transmitted segments of TCP data is a stand-alone acknowledgement.
11. The method of claim 7 wherein other data is received with the uplink segment.
12. The method of claim 7 wherein at least one of the buffering segments, transmitting the buffered segments, counting the number, transmitting the message, or receiving the uplink segment is performed by at least one of a base station, Node-B, or radio network controller (RNC).
