A multipath transmission control method oriented to deadlines of data blocks, includes: allocating transmission paths and timeslots to multiple data blocks to be sent at a sender according to heterogeneous attributes of the multiple data blocks and current network conditions, wherein the heterogeneous attributes comprise deadlines, sizes and priorities of the multiple data blocks; determining whether sending condition changes; and when the sending condition changes, rescheduling the multiple data blocks to be sent.

Certain aspects of the present disclosure provide improved techniques for monitoring a downlink control channel. For example, a method includes switching, at a first time period, to monitoring a downlink control channel according to a second group of search space sets in an unlicensed spectrum. The method further includes switching, after the first time period, to monitoring the downlink control channel according to a first group of search space sets in the unlicensed spectrum based on at least one of: i) expiration of a timer started based on the switching to monitoring the downlink control channel according to the second group of search space sets; or (ii) end of a channel occupancy time (COT), of a serving cell, during which the UE monitors the downlink control channel according to the second group of search space sets.

A base station may transmit a DCI comprising a HARQ process number field, comprising first bit(s), and an RV field comprising second bit(s). The base station may receive a TB in response to validation of the DCI. The validation may be based on the second bit(s). The validation may be based on comparing the first bit(s) with a first sequence of bit(s), determined using a first configuration parameter, in response to the first bit(s) not indicating a configuration index and the DCI having a first format. The validation may not be based on comparing the first bit(s) with the first sequence in response to the DCI having a second format.

A terminal according to an aspect of the present disclosure includes: a control section that calculates a pathloss based on a reference signal of a transmission configuration indicator (TCI) state of a specific downlink resource in a case where a pathloss reference signal and spatial relation information are not configured for specific uplink transmission; and a transmitting section that performs the specific uplink transmission using transmission power based on the pathloss. According to an aspect of the present disclosure, a reference signal for at least one of QCL and pathloss calculation for uplink transmission can be appropriately determined.

Methods and systems are provided for signaling for semi-static configuration in grant free uplink transmissions. Radio resource control (RRC) signaling is used to provide information from a base station to a user equipment (UE) that configure the grant free transmission resource to be used by the UE. In some implementations, the RRC signaling may be used in conjunction with system information that is transmitted to all UEs and/or Downlink Control Information (DCI) that the UE needs to access subsequent to the RRC signaling. In some implementations, the DCI includes an activation or deactivation indicator that the UE monitors to determine when the UE is allowed to transmit to the BS or should stop transmitting. Implementations allow for grant free transmission resources to be configured on an individual user based and a group basis.

The embodiments of the disclosure provide a bandwidth switching method and a user equipment. The method includes: when a BWP switching command is received while successfully receiving the random access completion message of the non-contention-based random access process, determine the non-contention-based random access process has been completed successfully in accordance with random access completion message, and determine not to perform the BWP switching process, or perform the BWP switching process in accordance with the random access completion message and the BWP switching command.

Methods, systems, and devices for wireless communications are described that support techniques for wireless communications using preconfigured uplink resources. Generally, the described techniques provide for enhancement of communication features including frequency hopping, an uplink control channel, coverage enhancement, timing advance, uplink power control, reconfiguration, a downlink control channel, a downlink data channel, retransmissions, or subcarrier spacing for a UE in idle mode. The UE may receive an uplink resource configuration for uplink communications in idle mode, the uplink resource configuration comprising an indicator associated with allocated resources for the uplink communications in idle mode and a set of parameters. The UE may transmit, while in idle mode, a first uplink transmission associated with a transport block on the allocated resources and according to one or more of the parameters, and monitor for a response to the first uplink transmission.

Embodiments of apparatus and method for implementing weighted overlap-and-add (WOLA) after digital gain adjustment are disclosed. In an example, an apparatus for wireless communication includes a baseband chip and a radio frequency (RF) chip including a digital front-end. The baseband chip is configured to generate a stream of orthogonal frequency-division multiplexing (OFDM) symbols and adjust gains of the stream of OFDM symbols. The baseband chip or the RF chip is configured to apply WOLA to the stream of OFDM symbols having the adjusted gains.

The present disclosure provides a method and a device in a node used for wireless communications. A first node receives a first reporting configuration and a first signaling; and transmits a first information block. The first signaling indicates a first transmission configuration state; the first information block comprises a reporting for the first reporting configuration; the first reporting configuration comprises N resource configurations; the N resource configurations respectively correspond to N first-type indexes; the first transmission configuration state corresponds to a first index; the first index is used to determine a first resource configuration; a measurement on reference signal resource(s) only in the first resource configuration among the N resource configurations is used to generate the first information block. The above method ensures that a TCI state of reference signals constantly matches with configuration information with the beams being dynamically updated.

A base station transmits parameters of cells grouped into control channel groups comprising: a primary control channel group; and a secondary control channel group. The secondary control channel group comprises: a control channel secondary cell with a secondary control channel; and a secondary cell. A radio link issue with the control channel secondary cell of a wireless device is detected. At least one command to deactivate the secondary cell for the wireless device is transmitted in response to the radio link issue.
