Abstract: The present technology aims to achieve flexible transition of a communication apparatus from a centralized communication mode to another mode. A communication apparatus includes: a transition information generation unit that generates a plurality of pieces of different transition information related to transition from a first mode in which centralized communication is performed by an access point to a second mode in which no centralized communication by an access point is performed; and a frame generation unit that generates a frame containing the transition information.

Abstract: A random access method includes: initiating, by user equipment (UE), a random access based on at least one of: initial access, uplink synchronization loss, or reconstruction; selecting, by the UE, a beam to transmit a preamble; determining, by the UE, whether a currently selected beam for transmitting the preamble is identical to multiple recorded beams previously selected for transmitting the preamble; determining, by the UE, that the currently selected beam is identical to one of the multiple recorded beams; determining, by the UE, a value of a pilot power boost counter not to reach a maximum value; and transmitting, by the UE, the preamble at a boosted pilot transmit power.

Abstract: Embodiments of the present disclosure relate to a device, a method, an apparatus and a computer readable storage medium for bandwidth part (BWP) switching. In example embodiments, a method is provided. The method comprises determining, at a terminal device, whether continuous Listen-Before-Talk (LBT) failures occur on a first bandwidth part (BWP), the terminal device operating on the first BWP. The method further comprises in response to the continuous LBT failures occurring on the first BWP, switching to a second BWP different from the first BWP. Instead of triggering a re-establishment procedure once continuous LBT failures are detected, switching to another BWP on different LBT sub-channels can be much more efficient than going through the whole re-establishment and reconfiguration procedures.

Abstract: Wireless communication under IEEE 802.11 standards utilizing carrier specific interference mitigation where an AP or UE employs an ultra-wideband tuner to evaluate available spectrum between several communication bands. Rather than being constrained to communicate in a single communication band, the AP and UEs may utilize more than one communication band to communicate with one another. In doing so, the AP and UE search across several bands and measure interference on a carrier-by-carrier basis across those bands. Either of the AP and UE may select a cluster of carriers for communication, where the cluster of carriers may comprise 1) contiguous carriers in a single sub-channel, 2) contiguous carriers spanning across more than one sub-channel, 3) discontinuous carriers in a single sub-channel, or 4) discontinuous carriers spanning across more than one sub-channel. The mapping between a cluster and its carriers can be fixed or reconfigurable.

Abstract: The present disclosure relates to a user equipment (UE) that comprises a receiver, which receives a plurality of random access type threshold values. A processing circuitry of the UE determines a random value and then selects a type of a random access procedure to be performed by the UE. The selecting comprises at least selecting one out of the plurality of random access type threshold values, comparing the determined random value against the selected random access type threshold value, and selecting a type of the random access procedure based on the result of the comparison. The UE then performs the random access procedure of the selected type.

Abstract: Embodiments of the present disclosure relate to random access in a communication system. A first device determines whether a contention-free random access resource is allocated from a second device for a first random access type. In accordance with a determination that the contention-free random access resource is allocated, the first device compares a target transport block size corresponding to the contention-free random access resource with a first transport block size configured for a first group of preambles available for the first random access type, and performs random access to the second device based on a result of the comparison.

Abstract: In an AP, a Trigger frame generator generates a trigger signal instructing an uplink signal transmission, the trigger signal including a terminal information field that includes a terminal ID subfield and a resource unit allocation information subfield, and a radio transmitter/receiver transmits the trigger signal. In a case where the trigger signal includes a first terminal information field specifying one or more contiguous resource units for random access, the Trigger frame generator sets an unused ID that is not to be used as a terminal ID in the first terminal information field.

Abstract: Techniques discussed herein can facilitate autonomous user equipment beam failure recovery abort aspects. One example aspect is a baseband processor configured to, when executing instructions stored in a memory, perform operations comprising: detecting a beam failure of a downlink (DL) beam; determining that a beam recovery abort condition is satisfied after detecting the beam failure; aborting a random access channel (RACH) transmission when the beam recovery abort condition is satisfied; and maintaining a connection with the DL beam after aborting the RACH transmission.
