Abstract: 경합하는무선기술을포함하는라디오주파수(RF) 대역에서동작하는 LTE 통신을채용하는사용자장비(UE)의경합윈도를증대시키기위한시스템및 방법에제공된다. 한가지실시예에서, eNodeB가데이터의전송블록을사용자장비(UE)로부터수신한다. 상기전송블록은주기적과잉체크(cyclic redundancy check; CRC)를포함한다. 이어서, eNodeB는상기 CRC에기초하여, 상기전송블록의체크섬(checksum)을판단하고, 그체크섬에실패하고, 그실패한체크섬에기초하여상기전송블록의비-확인응답(NACK)을상기 UE에전송한다. 상기 UE는그 NACK에응답하여, 경합윈도를증대시키고, 상기전송블록을 eNodeB에재전송한다.

Abstract: Systems and methods presented herein provide for channel reservation for a wireless telephony system operating in an RF band with a wireless system comprising a conflicting wireless technology. One method is operable with an eNodeB. The method includes assigning an ID (e.g., a PN sequence) to a user equipment (UE) operating in the RF band, processing a scheduling request for uplink (UL) data from the UE, and granting a time and a frequency for the UE to transmit the UL data. The method also includes waiting until the UE performs a Listen Before Talk (LBT) operation to determine whether the granted time and frequency is occupied by another wireless system employing a different wireless technology. The method also includes transmitting the ID to the UE to reserve the granted time and frequency when unoccupied by the other wireless system, and processing the UL data from the UE.

Abstract: Systems and methods presented herein provide for increasing a contention window of a UE employing a LTE communications operating in a radio frequency (RF) band comprising a conflicting wireless technology. In one embodiment, an eNodeB receives a transport block of data from a user equipment (UE). The transport block includes a cyclic redundancy check (CRC). The eNodeB then determines a checksum of the transport block based on the CRC, fails the checksum, and transmits a non-acknowledgement (NACK) of the transport block to the UE based on the failed checksum. The UE, in response to the NACK, increases a contention window and re-transmits the transport block to the eNodeB.
