摘要： The invention relates to a method and apparatus for enhancing transmission of a downlink ACK/NACK signal in an LTE communication system. In order to attain the object of enhancing transmission of a downlink ACK/NACK signal, the invention proposes an enhanced design of the current PHICH and thus makes an enhanced PHICH (E-PHICH). The enhanced design is focused primarily upon the following aspects: the first aspect is to configure an E-PHICH in the legacy PDSCH and to transmit an ACK/NACK signal in the E-PHICH so that a UE demodulates the E-PHICH to obtain the ACK/NACK signal. The second aspect is to improve a PHICH-and-PUSCH association design by designing an implicit association between an E-PHICH index and a radio frequency resource occupied by a UL grant (in a legacy PDCCH or an E-PDCCH) and an explicit association between a PUSCH scheduled by a UL grant and an E-PDCCH respectively and to transmit an ACK/NACK signal in the E-PHICH so that a UE demodulates the E-PHICH to obtain the ACK/NACK signal. With the invention, transmission of a downlink ACK/NACK signal in an LTE communication system can be enhanced.

摘要： The present disclosure discloses a method and device used in wireless communication node. A first node receives first information and second information via an air interface, the first information indicating a first time offset value, and the second information indicating a first time-domain resource relative to a first instant of time; the first instant of time is associated with a first time unit. By designing the first time offset value in the present disclosure, whenever a terminal A expects a terminal B to transmit, the terminal B is able to transmit according to a timing obtained by itself and there is no need for multiple interactions between these terminals to acquire a timing advance (TA), thus improving radio signal transmission efficiency on sidelink in IOT and V2X systems and the system's overall performance.

摘要： The present disclosure provides a method and a device in a node for wireless communications. A first node receives a first signaling, the first signaling being used to determine K time-frequency resource pools; and transmits a first signal in a first time-frequency resource set; the first time-frequency resource set belongs to a first time-frequency resource pool, the first time-frequency resource pool being one of the K time-frequency resource pools; K time offsets respectively correspond to the K time-frequency resource pools, and the first signaling is used to determine the K time offsets corresponding to the K time-frequency resource pools; a first time offset corresponds to the first time-frequency resource pool. The present disclosure designs a first signaling to flexibly configure time-domain resources used for sidelink transmission, thus avoiding interferences between cellular link and sidelink in a system larger transmission delay.

摘要： A method for determining resources to be decoded by the UE to retrieve physical downlink control channels. A method is in a UE or an eNB and comprises the following steps of: i. determining a start position of a unit of resources in one physical resource block pair; ii. determining a gap between two of the units; and iii. determining a set of units, in a given plurality of physical resource block pairs, according to said start position and said gap, as the resources to be decoded. In this way, the eNB and the UE can locate all the resources for the EPDCCH, namely the search space is determined. This aspect allows a balance between the number of blind decoding and eNB scheduling flexibility in the EPDCCH search space.

摘要： A method and a device in communication nodes used for wireless communications. A communication node receives first information, transmits a first radio signal, and monitors a first-type signaling in a first time window. Wherein an end time for a transmission of the first radio signal is used for determining a start of the first time window, and a time-domain resource occupied by the first radio signal is used for determining a first characteristic identity. The first characteristic identity is one of M characteristic identities, M being a positive integer greater than 1, and the first information is used for determining the M characteristic identities. The first-type signaling carries one of the M characteristic identities, and the communication node determines a characteristic identity carried by the first-type signaling out of the M characteristic identities through blind detection. The random access performance is therefore improved.
