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： 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 comprising configuration parameters indicating a sounding reference signal (SRS) resource set. A downlink control information is received. The downlink control information comprising an SRS resource indicator (SRI) and an uplink transmission configuration indicator (UL-TCI). The SRI indicates one or more SRS resources of the SRS resource set. In response to the UL-TCI being equal to a predefined value, a determination is made of an uplink spatial domain transmission filter based on the one or more SRS resources of the SRS resource set. A transport block with the uplink spatial domain transmission filter is transmitted via a physical uplink shared channel.

摘要： A wireless device receives from a second base station, a RRC message comprising access information, for a handover to a first cell of a first base station, indicating that a first timing advance of a first beam of the first cell is a timing advance of a first timing advance group of a secondary cell group and that a second timing advance of a second beam of the first cell is a timing advance of a second timing advance group of the secondary cell group. The wireless device selects, as a selected beam, one of the first beam and the second beam. The wireless device transmits transport blocks, via the selected beam of the first cell, using one of: the first timing advance in response to the selected beam being the first beam; and the second timing advance in response to the selected beam being the second beam.

摘要： A wireless device receives radio resource control message(s) from a base station indicating random access resources of an uplink bandwidth part of a cell, that comprise two-step random access resources and four-step random access resources. Determining that the two-step random access resources comprise contention-free two-step random access resources, the wireless device selects from among a two-step random access type and a four-step random access type, the two-step random access type. Based on the two-step random access type, a preamble is transmitted to the base station using the two-step random access resources.

摘要： A wireless device receives a first message indicating a first transmission configuration indicator (TCI) state being applicable at a first time for receiving a downlink control channel. A second message is received and indicates a common TCI state being applicable at a second time for: receiving the downlink control channel; and receiving downlink data via a downlink shared channel. The wireless device determines that the second message is received after the first message and that the second time is earlier than the first time. Based on the determining, the downlink control channel is received based on the common TCI state and the downlink data is received via the downlink shared channel based on the common TCI state.

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 may receive one or more radio resource control (RRC) messages. The RRC messages may indicate a first transmission and reception point (TRP) of a cell, a second TRP of the cell, and one or more first beam failure recovery parameters indicating one or more first reference signals for first TRP. The wireless device may determine a first beam failure of the first TRP based on the one or more first reference signals indicated by the one or more first beam failure recovery parameters. The wireless device may transmit an uplink signal via the second TRP of the cell indicating a link recovery request for the first TRP. The wireless device may receive an uplink grant for uplink data. The wireless device may transmit the uplink data indicating a candidate beam of the first TRP.

摘要： A base station determines to activate an antenna panel for transmission of a transport block. A determination is made for a time domain resource assignment field in a downlink control information (DCI), a slot offset value based on an activation delay of the antenna panel such that the slot offset value is larger than the activation delay. The base station transmits the DCI scheduling the transmission of the transport block.
