Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a control signal indicating a resource allocation for either an uplink transmission or a downlink transmission. The UE may identify, based at least in part on a modulation and coding scheme indicated in the control signal, an aggregation factor of the uplink transmission or the downlink transmission. The UE may communicate with the base station by either transmitting the uplink transmission or receiving the downlink transmission in accordance with the resource allocation and the aggregation factor.

The disclosure provides a method and a device in a communication node for wireless communications. The communication node first receives first information and then receives a first radio signal; only X1 bit(s) in a first bit block is(are) used for generating the first radio signal, the first bit block is obtained as an output of channel coding of a first code block, the first code block includes a positive integer number of bit(s), and the first bit block includes a positive integer number of bit(s); when channel decoding fails, at least X2 bit(s) in the first bit block can be used for decoding of the first code block with combining, the first information is used for determining the X2 bit(s), and the X2 is a positive integer. The disclosure reduces requirements on a buffer and reduces complexity.

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.

Proposed are a method and apparatus for receiving a PPDU in a wireless LAN system. Specifically, a reception STA receives a PPDU from a transmission STA through a broadband and decodes the PPDU. The PPDU includes a control field and a data field. When the broadband is a 320/160+160 MHz band including first to fourth 80 MHz sub-channels, the first 80 MHz sub-channel includes a first 996 RU, the second 80 MHz sub-channel includes a second 996 RU, the third 80 MHz sub-channel includes a third 996 RU, and the fourth 80 MHz sub-channel includes a first 484 RU. The data field is received through a first multiple RU in which the first to third 996 RUs and the first 484 RU are aggregated.

Proposed are a method and apparatus for receiving a PPDU in a wireless LAN system. Specifically, a reception STA receives a PPDU from a transmission STA via a broadband and decodes the PPDU. The PPDU includes a control field and a data field. When the broadband is a band of 320/160+160 MHz including a primary channel of 160 MHz and a secondary channel of 160 MHz, the data field is received via a first multiple RU in which a 996-RU and a 484-RU are aggregated. The first multiple RU is allocated within the primary channel of 160 MHz or the secondary channel of 160 MHz.

There are provided mechanisms for monitoring search spaces. A first method performed by a wireless device comprises receiving an Orthogonal Frequency-Division Multiplexing (OFDM) symbol in a downlink slot. At least part of the OFDM symbol is included in a device-specific search space and in a common search space. The first method comprises monitoring the device-specific search space for at least one device-specific reference signal (RS) and monitoring the common search space for at least one non-device-specific RS. In a second method, a radio access network node transmits an OFDM symbol included in a device-specific search space and in a common search space. The device-specific search space contains a device-specific RS, or the non-device specific search space contains a non-device-specific RS, or both of these apply.

A technique for power control including receiving, by a user device, a resource block allocation for uplink transmission that includes one or more resource blocks within a frequency channel; determining at least one resource allocation region or which an uplink resource block allocation within the resource allocation region will require an additional maximum power reduction (e.g., to reduce interference to a protected frequency band); and applying, by the user device, the additional maximum power reduction for a transmission power of the user device based on the resource block allocation being within the at least one resource allocation region.

A wireless device receives, from a base station, one or more radio resource control (RRC) messages that includes one or more configuration parameters for a cell. The one or more configuration parameters include a unified transmission configuration indicator (TCI) state type parameter that indicates a unified TCI state type among a separate unified TCI state type and a joint unified TCI state type. The wireless device may then communicate, with the base station and via the cell, based on the indicated unified TCI state type.

Embodiments described herein relate to real-time streaming of large quantities of time critical data over multiple distinct networks from a communications device. More specifically, embodiments described herein may address challenges and problems of maintaining consistent data reception quality when faced with the anomalies of a moving sender that is sending data using a relatively unstable method. This may be achieved by converting single source data into multiple data streams, placing them in transport buffers and storing them for forwarding.

A method of transmitting and receiving signals in a wireless local area network (WLAN) system and a device for the same are provided. More particularly, there are provided a method and a device for the same in which a station operating in an orthogonal frequency division multiplexing (OFDM) mode transmits and receives signals through two aggregated channels.
