Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a set of reference signals (RSs) that are associated with a reduced activation time. The UE may receive activation signaling identifying a transmission configuration indicator (TCI) state associated with an RS, of the set of RSs, to be activated for a communication. The UE may perform the communication using the identified TCI state, wherein the identified TCI state is activated within the reduced activation time after the activation signaling is received. Numerous other aspects are described.

In a case where a frequency band in which a wireless network 101 is established by a communication device (102) is switched from a 6 GHz band to another frequency band, the communication device (102) generates a management frame complying with Institute of Electrical and Electronics Engineers (IEEE) 802.11 series standards including Robust Security Network Element (RSNE) including a value “1” in a Management Frame Protection Capable (MFPC) field and a value “0” in a Management Frame Protection Required (MFPR) field, and transmits the generated management frame.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, an indication of a monitoring window used by the base station to monitor for uplink transmissions from the UE. The UE may receive a control signal scheduling uplink resources for an uplink transmission by the UE on at least a first component carrier, the first component carrier in a first radio frequency spectrum band. The UE may reconfigure, in response to the received control signal, a first transmit chain of the UE from a second component carrier in a second radio frequency spectrum band to the first component carrier in the first radio frequency spectrum band for the uplink transmission. The UE may transmit, based at least in part on the indicated monitoring window and using at least the reconfigured first transmit chain, the uplink transmission on the first component carrier using the scheduled uplink resources.

A user equipment (UE) may transmit a sounding reference signal (SRS) on a component carrier (CC) that is otherwise configured for downlink communications. Due to a carrier aggregation configuration or UE capability, the UE may need to retune certain components to transmit on the CC. If the SRS transmission, including the retuning time, collides with another transmission (e.g., in uplink or downlink) the UE may drop the SRS, drop the other transmission, or puncture the other transmission to facilitate the SRS transmission. The determination about a collision may depend on the retuning time, channel, or type of control information in the other transmission. In some cases, a UE may drop the other transmission if transmitting the SRS would prevent the UE from transmitting a demodulation reference signal, hybrid automatic repeat request (HARD) feedback. In some cases, the determination may be based upon a prioritization and may also depend on a subsequent subframe.

This invention relates to a proposal of an uplink resource assignment format and a downlink resource assignment format. Furthermore, the invention relates to the use of the new uplink/downlink resource assignments in methods for (de)activation of downlink component carrier(s) configured for a mobile terminal, a base station and a mobile terminal. To enable efficient and robust (de)activation of component carriers, while minimizing the signaling overhead, the invention proposes a new uplink/downlink resource assignment format that allow the activation/deactivation of individual downlink component carriers configured for a mobile. The new uplink or downlink resource assignment comprises an indication of the activation state of the configured downlink component carriers, i.e., indicate which downlink component carrier(s) is/are to be activated or deactivated. This indication is for example implemented by means of a bit-mask that indicates which of the configured uplink component carriers are to be activated respectively deactivated.

A method performed by a user equipment (UE) in a wireless communication system includes receiving, from a base station (BS), physical downlink shared channel (PDSCH) configuration information including a list of transmission configuration indicator (TCI) states, receiving, from the BS, a PDSCH media access control element (MAC CE) including information indicating activation of at least one TCI state in the list, identifying whether the PDSCH MAC CE is a MAC CE capable of indicating two or more TCI states for one TCI codepoint, receiving, from the BS, downlink control information (DCI) including information indicating a TCI codepoint, and receiving, from the BS, data via a PDSCH based on the information indicating activation of the at least one TCI state, a result of the identifying, and the information indicating the TCI codepoint.

Methods and apparatus for communicating and utilizing persistent allocation of resources are described herein. A base station may allocate persistent resources to a client station, and may associate the client station or persistent resource allocation with a particular shared NACK channel. The base station may monitor the NACK channel for a NACK indicating a map error. The base station may monitor the resource allocation to implicitly determine a map error. The base station may resend one or more persistent resource allocation information elements in response to the NACK or implicit error determination. A client station having a persistent resource allocation may monitor persistent resource allocation information elements in map messages and/or may indicate failure to receive a persistent resource allocation information element in a NACK message on a shared NACK channel.

Disclosed are a method, and terminal and network devices. The method includes a terminal device receiving first control information for scheduling a terminal device to perform data transmission; and the terminal device according to the transmission information of the terminal device and the first mapping relationship, determining at least one transmission frequency band corresponding to the transmission information. The first mapping relationship includes a correspondence between a plurality of pieces of transmission information and a plurality of transmission frequency bands. The transmission information includes at least one of: an attribute of the first control information, resource type information for the data transmission, and traffic information of the terminal device; the terminal device determining a target transmission frequency band from the at least one transmission frequency band. The terminal device performs data transmission with the network device on the target transmission frequency band according to the first control information.

In an embodiment, a user equipment (UE) receives, from an access node (AN), downlink control information (DCI) triggering a transmission of a sounding reference signal (SRS) of a SRS resource set. The DCI indicates a time-domain resource in available time-domain resources for transmitting the SRS resource set. The UE determines a position of the time-domain resource in the available time-domain resources based on the DCI, and transmits the SRS in accordance with the position of the time-domain resource. In another embodiment, a UE receives control information indicating a frequency resource in a carrier for transmission of one or more SRSs. The UE determines, based thereon, to segment the frequency resource into segments that each includes contiguous physical resource blocks (PRBs), and transmits a SRS in an orthogonal frequency division multiplexing (OFDM) symbol on a first segment and not on a second segment.

A wireless device receives one or more messages indicating transmission configuration indicator (TCI) states for downlink transmissions. The wireless device receives a medium access control control element (MAC CE) activating a plurality of TCI states of the TCI states. The wireless device receives, based on a reference signal identified during a random access procedure and before receiving downlink control information (DCI) indicating a TCI state from the plurality of TCI states, one or more downlink signals.
