    摘要： Systems and methods of HARQ codebook determination for multiple PUCCH are disclosed. In some embodiments, a method performed by a base station for constructing a semi-static HARQ codebook for each of multiple PUCCH resources in an uplink slot, each of the multiple PUCCH resources carrying HARQ feedback for PDSCH transmissions within a certain downlink time interval. The base station, based on a TDRA table, determines a sub-TDRA table for each downlink time interval comprising entries of the TDRA table with a TDRA ending in the downlink time interval. This includes pruning each sub-TDRA table to remove entries with overlapping TDRAs. The semi-static HARQ codebook is constructed for each pruned sub-TDRA table based on the remaining entries in the pruned sub-TDRA tables. The semi-static HARQ codebook is transmitted to the wireless device. In this way, it is possible to construct a semi-static HARQ codebook for multiple PUCCH transmission within a slot.

    摘要： Disclosed are a method and an apparatus for transmitting a hybrid automatic repeat request (HARQ) using a semi-persistent scheduling (SPS). The method for transmitting the hybrid automatic repeat request using the semi-persistent scheduling, which is applied to a network-side network element of an access network, includes: determining an identifier offset of an HARQ process using an SPS radio resource, and determining an identifier of the HARQ process according to the identifier offset of the HARQ process; and performing a transmission of the HARQ process corresponding to the identifier of the HARQ process with a user equipment.

    摘要： A method, system and network node are disclosed. A network node for communication with a wireless device that is configured for uplink transmission on a first carrier using a first Radio Access Technology (RAT) and on a second carrier using a second RAT is provided. The network node includes processing circuitry configured to determine whether to schedule the wireless device for uplink and whether to schedule the wireless device for uplink and downlink communications, in a transmission time interval (TTI) according to the first RAT based at least in part on an intermodulation distortion quantity associated with uplink communications according to both the first RAT and the second RAT, and optionally schedule the wireless device according to the determination.

    摘要： Disclosed is a wireless communication base station apparatus whereby it is possible to prevent degradation of throughput of LTE terminals, even when LTE terminals and LTE+ terminals are present together. In this apparatus, a setting section (105) sets in each subframe a resource block in which is arranged a reference signal that is employed solely by LTE+ terminals, based on the pattern of arrangement of reference signals employed solely by LTE+ terminals. In the case of symbols that are mapped to antennas (110-1) to (110-4), an arrangement section (106) arranges the characteristic cell reference signals employed by both LTE terminals and LTE+ terminals in all of the resource blocks in a single frame. In contrast, in the case of the symbols that are mapped to the antennas (110-5) to (110-8), the arrangement section (106) arranges in some of the resource blocks, that are set in accordance with the setting results input from a setting section (105), the characteristic cell reference signals that are employed solely by the LTE+ terminals.

    摘要： Methods, systems, and devices for wireless communication are described. A user equipment (UE) may indicate a UE capability for processing a physical downlink shared channel (PDSCH) and exclude an indication that the UE is capable of monitoring for more than one PDSCH transmission within a slot, per component carrier (CC). The UE may receive control information indicating a codebook configuration for hybrid automatic repeat request (HARQ) acknowledgment (ACK) and including a parameter that enables or disables such a capability for the UE to monitor for more than one PDSCH transmission within a slot. The UE may monitor for one or more downlink shared channel transmissions based on the control information and generate a HARQ-ACK codebook for the downlink transmissions, the codebook including feedback for one or more CCs based on the parameter in the control information.

    摘要： According to some embodiments, a method is performed by a wireless device operable to receive scheduling and data transmission from one or more downlink cells and perform uplink transmission with two or more uplink cells. The method comprises receiving scheduling for a downlink transmission in one of the downlink cells and scheduling for an uplink transmission in one of the uplink cells to provide feedback for the downlink transmission and determining whether the uplink transmission is scheduled at least a minimum processing time after the scheduled downlink transmission. The minimum processing time is based on a numerology of the downlink cells and the uplink cells. The method further comprises, upon determining that the uplink transmission is not scheduled at least a minimum processing time after the scheduled downlink transmission, transmitting an indication to at least one cell of the one or more downlink cells.
