摘要： Described are embodiments for transmitting hybrid automatic repeat request (HARQ) feedback information. In one embodiment, a wireless device receives a first downlink control information (DCI) indicating a first slot for transmission of uplink control information (UCI) comprising the HARQ feedback information. The wireless device receives a second DCI scheduling a plurality of physical uplink channels (PUSCHs) in a plurality of consecutive slots comprising the first slot. The wireless device multiplexes the UCI in a first PUSCH, of the plurality of PUSCHs, in the first slot. In response to a failed listen-before-talk (LBT) procedure for the first slot, the wireless device determines a second slot associated with a second PUSCH of the plurality of PUSCHs, and transmits, in response to a successful LBT procedure for the second slot, the UCI via the second PUSCH.

摘要： A wireless device sends a first radio resource control (RRC) message to a first base station. The first RRC message may indicate one or more first frequency band combinations that the wireless device is capable of communicating with the first base station. During an RRC connection with the first base station, a cell of a second base station for monitoring one or more downlink channels may be selected. One or more second frequency band combinations may be determined based on: one or more operating frequency bands of the cell; the one or more first frequency band combinations; and radio transceiver capability of the wireless device. During the RRC connection with the first base station, a second RRC message indicating the one or more second frequency band combinations may be transmitted to the first base station.

摘要： A wireless device may receive one or more messages comprising one or more configuration parameters for a cell. The one or more configuration parameters may indicate a sounding reference signal (SRS) resource for a configured uplink grant. An SRS resource set may comprise the SRS resource. The one or more configuration parameters may comprise a parameter that enables using default transmission parameters for SRS transmissions. The one or more configuration parameters may indicate no pathloss reference signal. The wireless device may transmit, with a transmission power determined based on a pathloss reference signal associated with the SRS resource set, a transport block of the configured uplink grant.

摘要： In an embodiment, a wireless device receives configuration parameters of a plurality of uplink (UL) transmission configuration indicator (TCI) codepoints. A first codepoint of the plurality of UL TCI codepoints indicates that an activated downlink (DL) TCI state is applicable for UL signal transmission. A second codepoint of the plurality of UL TCI codepoints indicates that a sounding reference signal resource indicator (SRI) is applicable for UL signal transmission. The wireless device receives a control command indicating a codepoint and determines a spatial domain filter based on the indicated codepoint being one of the plurality of UL TCI codepoints. The spatial domain filter is determined using: the activated DL TCI state based on the indicated codepoint being the first codepoint; and the SRI based on the indicated codepoint being the second codepoint. The wireless device transmits the UL signal using the determined spatial domain filter.

摘要： A wireless device receives configuration parameters indicating a bandwidth part (BWP), of a cell, associated with a maximum number of transmission layers and a plurality of demodulation reference signal (DMRS) ports. The wireless device receives a downlink control information comprising an antenna port indication value. A subset of DMRS ports, from the plurality of DMRS ports, is determined based on the maximum number of transmission layers associated with the BWP. A transport block is received via the BWP with one or more DMRS ports selected, based on the antenna port indication value, from the subset of DMRS ports.

摘要： A wireless device receives one or more radio resource control (RRC) messages. The RRC messages comprise: one or more first feedback parameters for selecting first feedback radio resources of a sidelink; and one or more second feedback parameters for selecting second feedback radio resources of the sidelink. A sidelink transmission comprising sidelink control information (SCI) indicating a priority level of the sidelink transmission is received. Based on the priority level, one or more radio resources are selected from one of: the first feedback radio resources based on the one or more first feedback parameters; and the second feedback radio resources based on the one or more second feedback parameters. A hybrid automatic repeat request (HARQ) feedback for the sidelink transmission is transmitted via the selected one or more radio resources.

摘要： A wireless device may receive one or more messages comprise parameters of a first downlink control information (DCI) format and a second DCI format for monitoring on a first search space. The parameters may comprise the second DCI format configured for monitoring on a second search space. The wireless device may determine, based on the first DCI format, a first DCI size of the second DCI format for the first search space. The wireless device may determine, based on the second DCI format, a second DCI size of the second DCI format in the second search space. The wireless device may monitor for a first DCI on the first search space based on the first DCI size. The wireless device may monitor for a second DCI on the second search space based on the second DCI size.

摘要： A wireless device selects a first a synchronization signal block (SSB), among SSBs of a cell, based on a signal quality measurement of the SSBs, and a second SSB, of the SSBs, based on the first SSB and a multiplexing pattern. The wireless device determines, based on the first SSB and the second SSB, monitoring occasions associated with a control resource set (coreset) to receive repetitions of downlink control information (DCI). The wireless device receives, via the determined monitoring occasions, one or more of the repetitions of the DCI.

摘要： A wireless device may receive one or more configuration parameters for a cell. The one or more configuration parameters may indicate a periodic resource configuration. The periodic resource configuration may be activatable by predetermined values of: a hybrid automatic repeat request process identifier (HARQ ID) field of a first downlink control information (DCI) format; and a redundancy version (RV) field of the first DCI format. The wireless device may receive a DCI based on a second DCI format without the HARQ ID field and/or the RV field. The wireless device may activate the periodic resource configuration based on: a size of the HARQ ID field of the DCI and/or the RV field of the DCI being zero; and the periodic resource configuration being in an inactive state.

摘要： A wireless device initializes a candidate resource set. The candidate resource set comprises candidate resources in a selection window. The wireless device receives a second sidelink transmission. The second sidelink transmission comprises sidelink control information (SCI). The SCI indicates first resources during the selection window. The SCI indicates a priority of the second sidelink transmission. The priority is used for excluding the first resources from the candidate resource set. The wireless device excludes the first resources from the candidate resource set based on the priority being higher than a first priority threshold. The wireless device selects second resources from the candidate resource set based on the excluding of the first resources from the candidate resource set. The wireless device transmits a first sidelink transmission via the second resources.
