The method comprises performing HARQ with a mobile station (MS) by a fixed HARQ period; and performing HARQ with a base station (BS) by a HARQ period series, wherein the HARQ period series comprises a plurality of HARQ period series element (X | 10-27-2011 |
20130343260 | METHOD FOR PERFORMING HARQ FOR RELAY STATION - A method for performing HARQ includes: receiving information to determine downlink subframes used for a relay station to receive scheduling information from a BS; determining uplink subframes for performing a HARQ with the DL subframes, each of the UL subframes corresponding to each of the DL subframes; assigning sequentially each of a plurality of HARQ processes to each of the UL subframes one by one; and performing HARQ with the BS at at least one of the HARQ processes. An n-th subframe is configured for a corresponding UL subframe if an (n-4)-th subframe is configured for one of the DL subframes, n denoting an integer. The HARQ processes are equal in number to the UL subframes. The DL subframes are configured in at least one radio frame having 10 subframes indexed from 0 to 9. Subframes having indexes 0, 4, 5 and 9 are not configured as a DL subframe. | 12-26-2013 |
20140334403 | METHOD FOR TRANSMITTING OR RECEIVING INTERFERENCE INFORMATION AND APPARATUS THEREFOR - A method for receiving information for interference cancellation of a mobile station (MS) is disclosed. The method is performed by the MS and includes receiving a restricted virtual radio network temporary identifier (V-RNTI) set including a plurality of V-RNTIs for interference signal cancellation from a serving base station (BS), wherein each of the plurality of V-RNTIs is associated with one or more RNTIs of one or more MSs served by a neighboring cell (hereinafter, “neighboring MS”), and receiving downlink control channel including a cyclic redundancy check (CRC) bit scrambled by at least one V-RNTI of the restricted V-RNTI set, for the neighboring MS, using the at least one V-RNTI, wherein, if two or more neighboring MSs having RNTIs associated with a specific V-RNTI among the plurality of V-RNTIs are scheduled at the same time, the specific V-RNTI is used only for downlink control channel for one of the two or more neighboring MSs. | 11-13-2014 |
20150049740 | METHOD AND APPARATUS FOR TRANSMITTING SIGNAL IN DEVICE-TO-DEVICE COMMUNICATION - A method for transmitting an uplink signal of a user equipment (UE) in a wireless communication system includes receiving an uplink (UL) grant from a serving base station and performing UL transmission based on the UL grant or device-to-device (D2D) communication, according to a configuration for D2D communication and a configuration of transmission time interval (TTI) bundling. When bundled UL transmission based on the UL grant and transmission for D2D communication are scheduled in the same TTI, the UL transmission scheduled in the TTI is performed in a first available TTI after the TTI, and, when two bundled UL transmissions according to two different UL grants are scheduled in the same TTI, bundled UL transmission according to the later received UL grant of the two different UL grants is dropped. | 02-19-2015 |
20150131522 | METHOD FOR PERFORMING HARQ FOR RELAY STATION - A method for performing HARQ includes: receiving information to determine downlink subframes used for a relay station to receive scheduling information from a BS; determining uplink subframes for performing a HARQ with the DL subframes, each of the UL subframes corresponding to each of the DL subframes; assigning sequentially each of a plurality of HARQ processes to each of the UL subframes one by one; and performing HARQ with the BS at at least one of the HARQ processes. An n-th subframe is configured for a corresponding UL subframe if an (n−4)-th subframe is configured for one of the DL subframes, n denoting an integer. The HARQ processes are equal in number to the UL subframes. The DL subframes are configured in at least one radio frame having 10 subframes indexed from 0 to 9. Subframes having indexes 0, 4, 5 and 9 are not configured as a DL subframe. | 05-14-2015 |
20150156763 | METHOD AND DEVICE FOR ALLOCATING RESOURCE FOR UPLINK CONTROL CHANNEL IN WIRELESS COMMUNICATION SYSTEM - Provided are a method and a device for allocating a resource for an uplink control channel in a wireless communication system. The method for allocating a resource for an uplink control channel in a wireless communication system comprises: receiving at least one downlink subframe; and allocating a physical uplink control channel (PUCCH) resource for transmitting an acknowledgement/not-acknowledgement (ACK/NACK) for the at least one downlink subframe, wherein the PUCCH resource is allocated on the basis of a control channel element of a control channel for scheduling each of the at least one downlink subframe, and if a particular subframe that satisfies a particular condition is included in the at least one downlink subframe, a control channel element included in the special subframe is excluded from the control channel element used to allocate the PUCCH resource. | 06-04-2015 |
20150215080 | METHOD AND APPARATUS FOR TRANSMITTING ACKNOWLEDGEMENT - Provided is a method for transmitting hybrid automatic repeat request (HARQ) positive acknowledgement (ACK)/negative acknowledgement (NACK) in a wireless communication system, and a wireless device using the same. The wireless device receives information on the number of repetitions m (where m is an integer greater than 1) from a base station. The wireless device transmits a designated signal p times (where p is an integer greater than 0), and repeatedly transmits ACK/NACK on a downlink transmission block m-p times. | 07-30-2015 |
20150215097 | METHOD AND APPARATUS FOR SUPPORTING BURST TRANSMISSION IN A WIRELESS COMMUNICATION SYSTEM - A method for and apparatus for supporting burst transmission in a wireless communication system supporting multiple carriers is provided. A wireless device receives a PDCCH for the burst transmission via a first serving cell and transmits a response of the PDCCH via the first serving cell. And then, the wireless device receives PDSCHs for the burst transmission via a second serving cell and transmits a response of the PDSCHs via the first serving cell. | 07-30-2015 |
