Abstract: A method for determining coarse carrier phase and frequency offsets of an initial block of received M-QAM symbols includes creating a grid of discrete candidate phase offset values and for each candidate value: applying the candidate value to each symbol, applying a respective hard decision to each applied symbol, and computing a figure of merit based thereon. The candidate value having the best figure of merit is selected as an initial phase offset estimate. An initial frequency offset estimate is computed using the symbols updated with the initial phase offset estimate, their respective hard decisions, and an approximation of the complex exponential function. To track carrier phase and frequency offsets associated with a series of symbol blocks, for each symbol of a current block, set a binary trust weight based on comparison of a computed parameter with a threshold and use the binary trust weights to compute a phase offset error and a frequency offset error for the current block.

Abstract: One or more wireless stations may operate to configure direct communication with neighboring mobile stations, e.g., direct communication between the wireless stations without utilizing an intermediate access point. A mechanism for wireless stations to mitigate medium congestion in discovery windows may include suppressing solicited publisher responses via an SRF for a first time period and resetting the SRF after the first time period in order to receive updates from peer devices.

Abstract: A terminal apparatus includes a transmitter configured to transmit PUSCH data and a receiver configured to receive RRC information. The transmitter transmits the PUSCH data by using a resource associated with an HARQ process ID determined by symbol information for transmission of the PUSCH data, a period, and the number of HARQ processes. In a case that the receiver receives no response to the transmission of the PUSCH data with the HARQ process ID after the transmission of the PUSCH data is performed and before a timer included in the RRC information expires, the transmitter transmits new PUSCH data by using the resource associated with the HARQ process ID determined by the symbol information for the transmission of the PUSCH data, the period, and the number of HARQ processes.

Abstract: Technology for a user equipment (UE), operable for an uplink partial subframe transmission on an unlicensed carrier is disclosed. The UE can select one or more uplink (UL) partial subframe configurations based on one or more prospective lengths of a listen before talk (LBT) period, wherein each prospective length of the LBT period provides a prospective starting time. The UE can encode data for each of the one or more UL partial subframe configurations to form one or more UL partial subframe configuration encodings. The UE can identify an actual LBT period. The UE can select one of the one or more UL partial subframe configuration encodings for UL transmission of the data on the unlicensed carrier based on the actual LBT period and a corresponding prospective starting time.

Abstract: Fast calculation of channel state information using demodulation reference signals (DM-RS) is provided herein. Channel state information is traditionally calculated based on the channel state reference signals (CS-RS). Demodulation reference signals, which are used for channel estimation for a data channel, are transmitted at different times than CS-RS however, and so some portions of the channel state information including layer indicator (LI) and channel quality indicator (CQI) can be calculated based on the demodulation reference signals, allowing a network to adapt more quickly to changing channel conditions, without having to transmit a CS-RS. Generally, precoding matrix indicator and rank indicator, which cannot be determined based on the DM-RS, don't change as often and are more stable over time, thus do not need to be calculated as frequently as the LI and CQI.

Further, the base station adjusts an orientation of the base station antenna according to the optimal antenna orientation of the base station antenna.

For example, a mobile device may be in a busy mode, where a user associated with the mobile device is busy on a call, and/or in an entertainment mode (or other non-communication mode), where the user is utilizing entertainment functions provided by the mobile device (e.g., watching a video, playing a video game, listening to a podcast, and so on).

Abstract: Facilitation of hybrid automatic repeat requests (HARQ) can comprise a system that acquires information about the capability of a mobile device. Next, the system can configure the mobile device with multiple physical uplink control channel (PUCCH) resources and a number of repetitions within a slot for each antenna port of the mobile device. A network node can then transmit a downlink control channel to the mobile device and indicate the PUCCH resources for each antenna port. Consequently, the system can then detect a HARQ acknowledgment (ACK) from the mobile device from all of the PUCCH resources.

Abstract: A method includes receiving beacons originating from endpoints. The beacons are received during a single beacon interval and are sent using a power strength to reach nodes within physical proximity of the endpoints. The method also includes establishing a list including multiple endpoints from which a node receives the beacons at more than a threshold percentage of the beacon intervals. The method includes detecting that a threshold number of the beacon intervals have passed since receiving a most recent beacon from an endpoint. The method includes outputting a ping at full power strength to the endpoint requesting a response. When the response is not received from the endpoint, the method includes transmitting an outage alarm to a next topologically higher layer of a mesh network. The outage alarm includes an identification of the endpoint and a timestamp indicating when the first node received the most recent beacon from the endpoint.

Abstract: A system can facilitate assigning guaranteed bitrate (GBR) admission control thresholds in a network with multiple network slices serving multiple GBR services. Thus, each network slice can optionally have its own dedicated GBR admission. For example, based on a requested service, the system can compare a received quality indicator to a threshold value to determine if a bearer shall be admitted in accordance with dedicated GBR admission control region within its slice. If the slice does not have its own GBR admission control region or if its threshold is reached the system can compare the received quality indicator to another threshold value to determine if the bearer shall be admitted in accordance with a common GBR admission control region.

Abstract: This application relates to the mobile communications field, and in particular, to a random access technology in a wireless communications system. This application provides a method for sending a random access preamble sequence, an apparatus, and a system. In this solution, a terminal device obtains a cyclic shift value that satisfies a high-speed movement scenario and sends a random access preamble sequence corresponding to the cyclic shift value. Impact brought by the high-speed movement scenario is considered when the random access preamble sequence is determined, thereby avoiding interference between terminal devices in the high-speed scenario.

Abstract: Methods and an apparatus for performing synchronization in New Radio (NR) systems are disclosed. A frequency band may be determined and may correspond to a WTRU. On a condition that the operational frequency band is a lower frequency, a synchronization signal block (SSB) index may be implicitly.

A configuration of actually transmitted SSBs may be determined using a multi-level two stage compressed indication where SSB groups are determined based on a coarse indicator and actually transmitted SSBs with the SSB groups are determined based on a fine indicator.

Abstract: A repeater device in a communication network includes a microcomputer configured to determine whether the repeater device will function as a mirroring switch that generates and transfers a mirror frame, or as a mirror-transfer switch that transfers the mirror frame. When the repeater device functions as a mirror switch and performs port mirroring, the repeater device adds monitor port and destination port information of the mirroring switch to the mirror frame. When the repeater device functions as a mirror-transfer switch, the repeater device adds sender port and destination port information of the mirror-transfer switch to the mirror frame. A monitor device in the communication network uses information in the mirror frame to identify a mirror source device in the network.
