Abstract: An example communication system includes remote units, each which includes one or more radio frequency (RF) units to exchange RF signals with mobile devices, with at least some of the RF signals including information destined for, or originating from, a mobile device. A controller is separated from the remote units by one or more networks. The controller is connected to an external network, and is for implementing a scheduler. The scheduler is for allocating resources for transmission of data representing the information, and is configured to override a pending hybrid automatic repeat request (HARQ) transmission on a HARQ process by scheduling a new HARQ transmission on the HARQ process.

Abstract: Embodiments of the present invention provide a method for configuring a serving cell in dual connectivity, user equipment, and a base station, so as to reduce a time for completing pSCell configuration. A specific solution is: A master eNodeB sends system information to UE, where the system information carries indication information used to indicate whether an SFN of the master eNodeB and SFNs of multiple adjacent eNodeBs (one of the eNodeBs is used as a secondary eNodeB of the UE) have same parity, or carries SFNs of multiple adjacent eNodeBs; or the master eNodeB sends RRC connection reconfiguration signaling to the user equipment, where the RRC connection reconfiguration signaling carries indication information used to indicate whether an SFN of the master eNodeB and an SFN of the secondary eNodeB have same parity, or carries an SFN of the secondary eNodeB. The UE executes primary secondary cell pSCell configuration at the secondary eNodeB according to the RRC connection reconfiguration signaling; the UE may determine parity of the SFN of the secondary eNodeB according to the received indication information or the SFN of the secondary eNodeB, and then the UE performs random access to the SeNB. The embodiments of the present invention are applied to configuring a serving cell by UE.

Abstract: Methods, apparatuses and a user equipment for performing a Hybrid Automatic Repeat Request (HARQ) transmission in a downlink from a base station to at least one user equipment are provided. An exemplary method comprises receiving a HARQ feedback to a HARQ transmission performed with respect to a transport block. The method further comprises determining whether the HARQ feedback is an ambiguous HARQ feedback with respect to a negative acknowledgement or a discontinuous transmission. The method additionally comprises setting (S206) the ambiguous HARQ feedback as the negative acknowledgement or the discontinuous transmission based on the number of HARQ transmissions having been performed and the corresponding received HARQ feedbacks within a target number of HARQ transmissions counting from a first HARQ transmission. With the methods and apparatuses, the ambiguity of the HARQ feedback can be overcome and communication efficiency may be improved.
