The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments herein provide an apparatus and method for verifying authenticity of a BH-RLF. A method is provided for using a new message to verify the authenticity of the BH-RLF. A method is provided for using existing and/or message over an F1AP and an RRC to verify the authenticity of the BH-RLF. A method is provided for using a hash based procedure for protection of the BH-RLF indication. A method is provided for generating a unique secret key at an parent IAB node and a child IAB node to protect the BAP control messages. Further, a method is provided for re-using ICMP ping messages to check the destination availability based on a received BH-RLF indication.

A terminal according to one aspect of the present disclosure includes a receiving section that receives a medium access control-control element (MAC CE) to update a transmission configuration indication (TCI) state, and a control section that, when a configuration related to at least one of a spatial relation and a pathloss reference signal for a specific uplink signal satisfies an application condition, uses the TCI state for the pathloss reference signal from timing after transmission of a positive acknowledgment (ACK) to the MAC CE. According to one aspect of the present disclosure, it is possible to appropriately transmit a UL signal.

A system includes a first device and a second device coupled to a link. The first device is to transmit one or more request frames for synchronization of a data layer, each request frame including a quantity of bits and an error code. The second device is to receive a first set of bits corresponding to the quantity of bits in each request frame. The second device is to perform an error decode operation on the first set of bits using a first portion of the first set of bits and determine the first set of bits correspond to a frame boundary of the one more request frames responsive to a success of the error decode operation. The second device is to transmit an acknowledgement of the synchronization of the data layer based on determining the first set of bits corresponds to the frame boundary.

Aspects are provided allowing a base station to configure a UE to accumulate CSI over time for downlink data transmissions, and to transfer the accumulated CSI to a base station in a CSI report in response to a CSI report trigger event, thereby improving efficiency in CSI reporting and subsequent transmission reliability. Initially, the base station configures a CSI report trigger event and sends a plurality of data transmissions to a UE. The UE receives the data transmissions and then identifies the CSI report trigger event. Afterwards, the UE sends a CSI report to the base station including a CSI for each of the data transmissions in response to the CSI report trigger event. The base station may then adjust MCS or other parameters for subsequent data transmissions in response to the CSI report.

In the present invention, disclosed is a method for uplink multi-user transmission in a wireless communication system and an apparatus therefor. Specifically, a method for performing, by a station (STA), uplink (UL) multi-user (MU) transmission in a wireless communication system comprises the steps of: receiving, from an access point (AP), a trigger frame including information for UL MU transmission; and transmitting an UL MU PPDU on the basis of the information for UL MU transmission, wherein the trigger frame is a medium access control (MAC) frame, a MAC header of the trigger frame includes a type field and a subtype field, and the type of the trigger frame may be indicated by the type field and the subtype field.

Provided are a method, device and storage medium for configuring a starting symbol position of an uplink data channel. The method includes: determining a configuration value of a first type parameter set, where the first type parameter set is a set of uplink data parameters; determining a configuration range of a starting symbol position of an uplink data channel according to the configuration value of the first type parameter set; and selecting a starting symbol position of the uplink data channel from the configuration range of the starting symbol position of the uplink data channel, and notifying a receiving end of the selected starting symbol position of the uplink data channel.

The present disclosure relates to data transmission methods and apparatus. One example method includes sending, by a radio access network device, a first transport block to a terminal device, where the first transport block includes at least two code blocks, the at least two code blocks are divided into at least two different code block sets, and each code block set includes at least one of the at least two code blocks, and receiving, by the radio access network device, first feedback information sent by the terminal device, where the first feedback information includes at least two pieces of feedback information corresponding to the first transport block, and the at least two pieces of feedback information are respectively used to indicate receiving statuses of the at least two code block sets.

Disclosed are methods, systems and devices for channel state information feedback to facilitate, for example, high-performance beamforming or precoding in multiple input multiple output (MIMO) systems. One example method includes performing multiple transmissions of a channel measurement report on multiple transmission occasions. Another example method includes performing multiple receptions of a channel measurement report on multiple reception occasions, where the multiple receptions at a network node correspond to multiple transmissions from a wireless device. In both exemplary methods, a timing of the multiple transmissions is based on at least one of a number of the multiple transmission occasions, a time gap between adjacent transmission occasions of the multiple transmission occasions, and one or more timeslots that include the multiple transmission occasions.

A method and an apparatus for determining an RBG size are provided. In the method, a network device or a terminal determines an RBG size set, where the RBG size set may include one or more possible RBG sizes; and determines a first RBG size included in the RBG size set. The network device allocates a resource to the terminal by using the determined first RBG size. The terminal determines, based on the determined first RBG size, the resource allocated by the network device to the terminal.

Some embodiments of this disclosure include apparatuses and methods for implementing block acknowledgment (BA) operations for multi-link wireless communication networks. For example some embodiments relate to an electronic device including a transceiver and one or more processors communicatively coupled to the transceiver. The one or more processors transmit, using the transceiver and to a second electronic device, a first set of one or more frames on a first link and a second set of one or more frames on a second link. The one or more processors receive, using the transceiver and from the second electronic device, a first block acknowledgment (BA) frame on the first link and a second BA frame on the second link. The one or more processors further determine, based on received first BA frame and the second BA frame, a failed or missing frame of the first set of one or more frames transmitted on the first link.
