Abstract: A method in a first terminal device for facilitating direct communication with a second terminal device. The method comprises transmitting to the second terminal device a Modulation and Coding Scheme (MCS) index, based on which the second terminal device can obtain a modulation order and a Transport Block Size (TBS) in accordance with a first mapping or a second mapping between MCS indices on one hand and modulation orders and TBSs on the other. The MCS index is determined by the first terminal device by selectively applying the first or second mapping.

Abstract: Techniques may be used for restricted direct discovery in proximity services (ProSe). A ProSe function may receive from a discovery wireless transmit/receive unit (WTRU) a restricted ProSe Application identity (ID) of an application located at the discoverer WTRU requesting ProSe discovery. The ProSe function may derive a first and second ProSe codes for the discoveree WTRU and discoverer WTRU, and provide the ProSe codes to the discoverer and/or discoveree WTRUs. A ProSe application server may receive a revocation message from an announcing WTRU indicating a revoked WTRU. The ProSe application server may provide a ProSe discovery WTRU ID for the revoked WTRU to a ProSe Function. The ProSe function may instruct the announcing WTRU to stop announcing a ProSe code known by the revoked WTRU, and may provide a new ProSe code to at least one WTRU authorized to discover the announcing WTRU.

Abstract: Methods and apparatuses for signal processing at base station are disclosed. According to an embodiment, a digital unit (DU) compresses a block of baseband signal samples. The DU determines whether valley increment is to be applied on decompressed block of baseband signal samples by a radio unit (RU) connected with the DU, based on the compressed block. When determining that valley increment is not to be applied, the DU generates an indication for indicating not to apply valley increment. When determining that valley increment is to be applied, the DU determines information related to bit loss due to the compression. The DU sends, to the RU, the compressed block and the indication or the information related to bit loss.

Abstract: A wireless communication network serves a User Equipment (UE) with a Network Exposure Function (NEF) and multiple Unified Data Elements (UDEs) like Unified Data Managements (UDMs) and Unified Data Repositories (UDRs) The NEF receives initial network data and transfers a UDE query to a Network Repository Function (NRF). The NRF selects a Unified Data Proxy (UDP) and indicates the UDP to the NEF. The NEF receives the UDP indication and responsively transfers the initial network data to the UDP. The UDP receives the initial network data, and in response, selects one of the UDEs. The UDP transfers the initial network data to the selected one of the UDEs. The selected one of the UDEs receives the initial network data, and in response, generates and transfers new network data. In some examples, the UDEs comprise UDMs/UDRs that reside in different Public Land Mobile Networks (PLMNs) from one another and from the NEF.

Abstract: In order to maintain performance during wireless communication, a transmitting electronic device may selectively perform a remedial action based on a received power in a channel during time intervals between received packets (e.g., due to interference) and/or a metric associated with the measured received power. In particular, when the received power is less than a threshold value (e.g., when the interference is insufficient to stop transmission by the transmitting electronic device), the transmitting electronic device performs the remedial action based on the measured received power and/or the metric. For example, the remedial action may include: selecting a modulation technique; selecting the receiving electronic device; selecting an antenna pattern for the one or more antennas; reducing a transmit power; selecting a data rate; determining a cumulative distribution function; and/or estimating a channel capacity.

Abstract: Controlled-environment communication systems are increasingly using voice over internet protocol (VoIP) to serve their users. VoIP allows voice to be sent in packetized form, where audio is encoded using one of several codecs. Because of bandwidth constraints, particularly during peak call times, codecs may be used which sacrifice audio quality for bandwidth efficiency. As a result, several features of communication systems, including critical security features. The present disclosure provides details for systems and methods by which a controlled-environment communication system may shift between codecs to perform security-related features or to alleviate bandwidth considerations. This involves the special formatting of control-signaling messages, including session initiation protocol (SIP) and session description protocol (SDP) messaging.

Abstract: Wireless communication devices, systems, and methods related to mechanisms for transmitting and receiving reference signals in a high-speed train (HST) single frequency network (SFN). A base station (BS) determines a first frequency pre-compensation value for a reference signal transmitted via a first transmission and reception point (TRP) and a second frequency pre-compensation value for a reference signal via a second TRP. The BS notifies a user equipment (UE) of the first and second pre-compensation values through at least one of the TRPs. The BS applies the first pre-compensation value to the reference signal via the first TRP and the second pre-compensation value to the reference signal via the second TRP. The UE adjusts its tracking loop for the reference signal based on the pre-compensation values, reducing estimation and/or search overhead at the UE.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a transmitting device may be configured to transmit a transport block in a set of transmission time intervals (TTIs) of a repetition window to improve the chances that the transport block is received by a receiving device. In some cases, however, the transport block may not be available to be transmitted in the repetition window until after a first TTI of the repetition window. In such cases, a transmitting device may use the techniques described herein to identify appropriate configurations for transmitting the transport block in the repetition window. For example, the transmitting device may identify an adjusted redundancy version sequence to use for transmitting the transport block in the repetition window or the transmitting device may adjust a repetition window based on a TTI in which the transport block is available to be transmitted.
