METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING DATA IN A COMMUNICATION SYSTEM
The present disclosure relates to a fifth generation (5G) or pre-5G communication system to be provided to support a higher data transmission rate since fourth generation (4G) communication systems like long-term evolution (LTE). A method of a receiver in a wireless communication system is provide. The method includes receiving at least one packet, identifying whether there is a non-received packet among the at least one packet, and transmitting status report information when there is the non-received packet, in which the status report information includes a field indicating whether there are consecutively non-received packets.
Method and apparatus for sending harq-ack feedback codebook and device
This application provides methods and apparatuses for sending a HARQ-ACK feedback codebook. One example method includes detecting DCI in a plurality of time units corresponding to at least one carrier, where a type of the DCI is a first DCI type or a second DCI type, where the first DCI is used to indicate to feed back CBG-level HARQ-ACK information for data scheduled by the first DCI, and where the second DCI is used to indicate to feed back TB-level HARQ-ACK information for data scheduled by the second DCI. A HARQ-ACK feedback codebook is then sent to a network device, where the codebook includes HARQ-ACK information of at least one piece of data scheduled by the DCI, and the HARQ-ACK feedback codebook is determined according to the type of the DCI and a type of the HARQ-ACK feedback codebook.
Communication method and system for joint downlink and uplink transmissions
In a communication method to communicate between an access point (AP) and first and second communication stations (STAs) can include calculating joint transmission information based on the first and the second STAs, establishing an uplink communication between the AP and the first STA; and establishing a downlink communication between the AP and the second STA jointly with the uplink communication between the AP and the first STA based on the joint transmission information.
TRANSMITTING ACKNOWLEDGEMENTS
For transmitting acknowledgements, a method receives at least one first data block in at least one of a first plurality of short-type subframes. The method further transmits a first acknowledgement corresponding to the at least one first data block received in the first plurality of short-type subframes using a first long-type subframe. A duration of the first plurality of short-type subframes is equal to a duration of the long-type subframe.
MULTI-TRANSMISSION NEGATIVE ACKNOWLEDGEMENT INDICATION IN PHYSICAL SIDELINK FEEDBACK CHANNEL
Disclosed are techniques related to performing wireless sidelink communication. Originating (e.g., transmitting) and target (e.g., receiving) apparatuses may operate in a NACK-only mode. In this mode, the target apparatus only provides NACK feedbacks to transmissions that it did not receive. Lack of NACK feedback is interpreted by the originating apparatus that the transmissions were successfully received. However, the target apparatus maybe incapable of transmitting NACK for each of missed transmission. In NACK-only mode, the originating would not retransmit these missed transmissions. To address this issue, the target apparatus can transmit a multi-transmission NACK feedback to indicate that multiple transmissions were not successfully received. The multi-transmission NACK is a single feedback, and thus can enable a target apparatus with limited feedback capacity to indicate NACK for multiple transmissions.
SYSTEM AND METHOD FOR DYNAMIC MULTICARRIER ALLOCATION TO NB-IoT DEVICES
Present disclosure generally relates to wireless communication and particularly relates to system and method for dynamic multicarrier allocation to NB-IoT devices. Method includes receiving from PMS, PRB utilization data for a time slot or data packets, and comparing PRB utilization duration in received PRB utilization data with pre-defined threshold PRB utilization duration. Requesting via NB-IoT eNB, cumulative NACK percentage report corresponding to ARFCN/PRB, if PRB utilization duration is less than a pre-defined threshold. Method includes selecting, ARFCN/PRB for a time slot, based on PRB utilization data and cumulative NACK percentage report and pre-defined value. Method includes establishing connection between NB-IoT enabled devices and NB-IoT eNB, upon transmitting via LTE eNB, information associated with selected ARFCN/PRB for time slot, to NB-IoT eNB. Method includes notifying LTE eNB, representative of utilization of ARFCN/PRB as non-anchor carrier. Method includes allocating ARFCN/PRB as non-anchor carrier to schedule NB-IoT enabled devices for data transfer in selected time slot.
ADAPTIVE BLOCK ACKNOWLEDGEMENT NEGOTIATIONS
Examples of block acknowledgement negotiations are described. In an example, a request to establish a BA session is sent by a first computing device (first device) to a second computing device (second device). A timer for receipt of a response to the request is initialized. A BA successful response is received by the first device after the timer has timed out. A request to terminate the BA session is sent by the first device to the second device. After sending the request to terminate the BA session, BA negotiation is reinitiated by the first device based on an updated inactivity timer, so that there are greater chances of successfully establishing a BA session. In an example, if the second device ignores the request to terminate the BA session then it sends a BA reject response to the first device. After receiving the BA reject response, the first device waits for the inactivity timer before reinitiating BA negotiations, so that the second device clears its states thereby increasing chances of successful BA renegotiations.

A method of a receiver in a wireless communication system is provide. The method includes receiving at least one packet, identifying whether there is a non-received packet among the at least one packet, and transmitting status report information when there is the non-received packet, in which the status report information includes a field indicating whether there are consecutively non-received packets.
Wireless communication method using fragmentation and wireless communication terminal using same
Provided is a wireless communication terminal that communicates wirelessly. The terminal includes: a transceiver; and a processor. The processor is configured to transmit first information on a fragmentation level to be used for data to be transmitted to a recipient by using the transceiver in an add Block ACK (ADDBA) setup procedure.
System and method for speed frame exchange
In one embodiment, a method includes receiving, at a first time, by a first user equipment (UE) from a first device, a request to send (RTS) frame including a first duration and receiving, at a second time, by the first UE from a second device, a clear to send (CTS) frame including a second duration. The method also includes determining a duration of a speed frame exchange (SF) exchange in accordance with the first duration and the second duration.
