摘要： Described are embodiments for selecting a preamble for a random access procedure. In an embodiment, a wireless device receives one or more configuration parameters of physical random access channel (PRACH) occasions for the random access procedure. One or more PRACH occasions of the PRACH occasions correspond to a respective RS of a plurality of RSs. The wireless device determines a RS, from the plurality of RSs, based on a reference signal received power (RSRP) value of the RS, and a transmission power reduction value associated with the RS. The wireless device determines a PRACH occasion, associated with the RS, from the PRACH occasions. Then, the wireless device transmits, via the PRACH occasion, a preamble for the random access procedure.

摘要： A wireless device receives, from a base station, one or more messages indicating: a number of repetition transmission occasions for uplink transmission of a transport block; and an interval for switching uplink transmissions between a first panel and a second panel. Based on the interval, a determination is made of: a first portion of the number of repetition transmission occasions for uplink transmission of the transport block; and a second portion of the number of repetition transmission occasions for uplink transmission of the transport block. The first portion of the number of repetition transmission occasions of the transport block is transmitted via the first panel. The second portion of the number of repetition transmission occasions of the transport block is transmitted via the second panel.

摘要： A downlink control information (DCI) is received. The DCI indicates one or more transmission configuration indication (TCI) states. A first pathloss between a transmission reception point (TRP) and a first panel of a wireless device is measured based on one or more pathloss reference signals (RSs). A second pathloss between the TRP and a second panel of the wireless device is measured based on the one or more pathloss RSs. A pathloss is determined based on a quantity of the one or more TCI states indicated by the DCI. The pathloss is a combined pathloss based on the first pathloss and the second pathloss in response to the quantity being equal to one. The pathloss is one of the first pathloss and the second pathloss in response to the quantity being greater than one. A transport block is transmitted with a transmission power based on the pathloss.

摘要： A wireless device receives one or more messages comprising configuration parameters indicating a plurality of configured grant configurations for one or more bandwidth parts (BWPs) of a cell. A downlink control information is received. The downlink control information indicates activation or release of a first configured grant configuration, among the plurality of configured grant configurations, for a first BWP of the one or more BWPs. A confirmation indicating that the wireless device received the downlink control information indicating the activation or release of the first configured grant configuration is transmitted. The confirmation comprises at least one of: an identifier of the first BWP; and an identifier of a sub-band of the first BWP.

摘要： In some embodiments, a wireless device receives a plurality of downlink control information (DCIs) via a plurality of resource block (RB) sets of a bandwidth part of a cell. The plurality of DCIs indicate downlink radio resources. The wireless device receives a transport block via the downlink radio resources. Based on RB set indexes of the plurality of RB sets, the wireless device determines a DCI from the plurality of DCIs. Then, the wireless device transmits feedback information, for the transport block, via an uplink control channel resource determined based on the DCI.

摘要： Configuration parameters, of channel state information (CSI) resources for a first transmission reception point (TRP) and a second TRP of a cell, are received. One or more media access control control elements (MAC CEs) are received. The MAC CEs indicate a first semi persistent CSI report for the first TRP. The MAC CEs indicate a second semi persistent CSI report for the second TRP. First reference signal received power (RSRP) values, for the first semi persistent CSI report, are determined based on the plurality of CSI resources. Second RSRP values, for the second semi persistent CSI report, are determined based on the CSI resources. A codeword, comprising the first RSRP values and the second RSRP values, is created. The codeword is transmitted, based on the first semi persistent CSI report and the second semi persistent CSI report, via a physical uplink control channel resource.

摘要： A wireless device receives configuration parameters indicating a maximum permissible exposure (MPE) threshold. First uplink signals are transmitted via a first antenna panel. A downlink control information (DCI) indicating switching from the first antenna panel to a second antenna panel is received. An MPE event is detected based on the MPE threshold and a power value associated with the second antenna panel. Based on the detecting the MPE event: the switching indication is ignored by not switching to the second antenna panel; and second uplink signals are transmitted via the first antenna panel.

摘要： A wireless device receives a first downlink control information (DCI) scheduling a physical downlink shared channel (PDSCH). The first DCI comprises a feedback timing indicator field. In response to the feedback timing indicator field indicating not to transmit a feedback for the PDSCH before receiving a second DCI, a discontinuous reception (DRX) timer is started with a first value. A downlink control channel is monitored for the second DCI while the DRX timer is running.
