The present invention relates to methods for sending or receiving control data in one or multiple uplink control channel resources of a wireless communication network and to corresponding devices. According to one embodiment of the invention a method of sending control data in one or multiple uplink control channel resources of a wireless communication network is provided. A wireless device receives, from a network node, information on a set of downlink component carriers configured for the wireless device. The wireless device receives, from a network node, an indication of the one or multiple uplink control channel resources. The wireless device maps first control data comprising control data for the set of configured downlink component carriers to a part of the one or multiple uplink control channel resources. And the wireless device maps second control data to a remaining part of the one or multiple uplink control channel resources.

Communicating control data in a wireless communication network

A method is provided to improve resource utilization efficiency of an uplink control channel carrying feedback information, including: a terminal device receives one or more downlink channels carried in one or more first time units, which belong to a time unit set; determines a second time unit for carrying feedback information corresponding to the downlink channels according to a first association relationship between the time unit set and the second time unit; and sends uplink control information including a determined first codebook in the second time unit. When a downlink channel is received in first time units that belong to a subset of the time unit set, and there is a second association relationship between the subset of the time unit set and the second time unit, the first codebook includes only feedback information corresponding to the downlink channel carried in the first time units in the subset.

Feedback information transmission method and communication device

A base station (), a wireless device () and methods thereinfor supporting radio communication, wherein the base station () employs carrier aggregation with multiple carriers serving a primary cell, PCell, and at least one secondary cell, SCell. The base station () signals (3:3) an SCell status to the wireless device (), the SCell status indicating whether the at least one SCell will be in active state where the base station () transmits downlink signals on a carrier serving the at least one SCell, or in inactive state where the base station () does not transmit downlink signals on the carrier serving the at least one SCell. Thereby, the wireless device () can adapt its behaviour depending on the signalled SCell status, e.g. by turning off its receiver and not perform any signal measurements when the SCell is in inactive state.

Methods, base station and wireless device for supporting radio communication

A method, and related apparatuses are disclosed, to provide an MCS corresponding to a lower code rate. The communication method includes: sending a first CQI number to a network device, wherein the first CQI number is determined based on a first CQI table; and receiving an MCS number in a first MCS table from the network device, wherein the first MCS table comprises an entry that is not comprised in the first CQI table, and at least one entry whose modulation scheme is 64QAM in the first CQI table, wherein a BLER corresponding to the first CQI table is 10e-5, and values obtained by multiplying code rates by 1024 in the first CQI table comprise 30 and 50.

Communication method, MCS receiving method, MCS notification method, and device

The present disclosure relates to a method used in a User Equipment (UE) for reporting Hybrid Automatic Repeat Request (HARQ) acknowledgement (ACK)/non-acknowledgement (NACK) for Physical Downlink Shared Channels (PDSCHs) in dynamic time division duplex (TDD) configurations. In the method, a plurality of PDSCHs are received in DownLink (DL) subframes associated with an UpLink (UL) subframe and indicated by a DL reference TDD configuration. The DL subframes are divided into a first subset of DL subframes and a second subset of DL subframes. The first subset of DL subframes is also indicated by an UL reference TDD configuration. A first set of Physical Uplink Control Channel (PUCCH) resource indices are assigned based on resources used in transmission of Physical Downlink Control Channels (PDCCHs) corresponding to the PDSCHs received in the DL subframes of the first subset of DL subframes. A second set of PUCCH resource indices are assigned based on resources used in transmission of PDCCHs corresponding to the PDSCHs received in the DL subframes of the second subset of DL subframes. For each of the received PDSCHs, HARQ ACK/NACK is reported by using PUCCH resources in an order of the assigned first set of PUCCH resource indices for PDSCHs received in the DL subframes of the first subset of DL subframes and in an order of the assigned second set of PUCCH resource indices for PDSCHs received in the DL subframes of the second subset of DL subframes. The present disclosure also relates to a UE and BS for respectively reporting and receiving HARQ ACK/NACK for PDSCHs in TDD configuration.
