Abstract: An Open Radio Access Network Category B radio unit (O-RU) of a wireless network associates, for a first extended antenna carrier identifier (eAxC_Id) corresponding to a layer 0 precoding layer identifier (layerlD), the first eAxC_Id with one or more second eAxC_Ids. Each second eAxC_Id corresponds to a non -layer 0 precoding layerlD. The O-RU receives, for a user equipment (UE), a control plane message of Section Type 1 or 3. The message includes an extension type (ExtType) 3 first data layer, along with the first eAxC_Id in a transport header. The ExtType 3 first data layer indicates a number of precoding layers. The O-RU then precodes user plane data for downlink physical resource blocks allocated to the UE using the layer 0 precoding layerlD of the first eAxC_Id, and each associated non-layer 0 precoding layerlD of the one more second eAxC_Ids required to complete the number of precoding layers.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an open radio access network (O-RAN) distributed unit (O-DU) may generate, at an O-DU application that executes on the O-DU, a first message that does not make use of an O-DU accelerator of the O-DU that is in-line with the O-DU application. The O-DU may transmit, from the O-DU application to an O-RAN radio unit (O-RU), the first message via a passthrough of the O-DU accelerator, wherein the first message does not make use of the O-DU accelerator based at least in part on a payload of the first message being transferred unchanged by the O-DU accelerator to the O-RU. Numerous other aspects are described.

Abstract: A communication system is disclosed in which a mobile terminal having limited power is able to communicate with a land-based network via a low-rate satellite communication link. To achieve VoIP communications via a low-rate link, link-layer assisted zero-header header compression techniques are employed to reduce VoIP packet overheads. Additionally, overheads introduced by link layer protocol layers are eliminated or reduced. A transmitting device strips RTP / UDP / IP header information from a stream of VoIP packets. The transmitting device then sends an initial context message providing the RTP / UDP / IP header information. The stripped zero-header VoIP packets are then transmitted via a satellite relay. A receiving device uses the initial context information to reconstruct the headers for the zero-header VoIP packets.

Abstract: Apparatus, methods, and computer-readable media for facilitating simplified switching at an RU are disclosed herein. An example method for wireless communication at an RU includes transmitting, to a DU, capability information indicating support of endpoint groups, each endpoint group associated with a respective set of RU endpoints. The example method also includes receiving an eAxC message from the DU based on the capability information, the eAxC message including a DU port identifier, a band sector identifier, a component carrier identifier, and an RU port identifier. The example method also includes using a first portion of the RU port identifier to identify an endpoint group, the respective set of RU endpoints of the endpoint group associated with a set of characteristics. Additionally, the example method includes using a second portion of the RU port identifier to index the eAxC message to an RU endpoint of the endpoint group.

Abstract: A communication system is provided that allows a mobile terminal with an EVDO interface to perform VoIP communications via a satellite. The 1xEVDO physical layer frames and vocoder frames are synchronized and aligned to a known periodic time boundary for efficient transmission. A reverse link transmission rate is adjusted to match a VoIP packet source rate and operate the reverse link transmission channel to a satellite continuously. The reverse link transmission channel from a mobile terminal to a satellite may operate continuously and at a lower channel transmission rate to reduce the peak power amplifier power requirement. The higher layer time-out periods are increased to account for propagation delay to/from a satellite relay. A physical layer retransmit mechanism is disabled to ignore ACKs/ NACKs when sending VoIP packets via a satellite relay. A different channel code may be selective applied depending on the size/type of packets being transmitted.
