An apparatus includes a processor and a memory coupled to the processor. The memory stores instructions executable by the processor to perform operations that include determining a particular number of transport blocks associated with user equipment (UE) based on a plurality of channel quality indicator (CQI) indices received from the UE.

A satellite communications system can use a spread-spectrum waveform and format, a synchronization scheme, and/or a power management algorithm. This approach can provide benefits such as allowing every terminal to communicate with every other terminal, link margin permitting. This gives the network a mesh topology although it can be configured in a star topology for highly asymmetric applications. A further understanding of the nature and the advantages of particular embodiments disclosed herein may be realized by reference of the remaining portions of the specification and the attached drawings.

A cellular communication system comprising a plurality of geographically spaced base stations (2) each of which comprises an antenna arrangement (4, 6, 8) per base station sector, each of which antenna arrangements has an antenna element for generating an array of narrow beams (10, 12, 14) covering the sector. Timeslots are simultaneously transmitted over each of the beams so as to generate successive sets of simultaneously transmitted timeslots per sector. The timeslots are each split into multiple orthogonal codes, for example Walsh codes. The communication system additionally comprising a scheduling device (31) for allocating for successive sets of timeslots common overhead channels, including a common pilot channel, which are allocated to the same sub-set of codes of each timeslot in the set. For successive sets of timeslots different data traffic is allocated to the same sub-set of codes of each timeslot in the set. This effectively generates a sector wide antenna beam carrying the common overhead channels and a plurality of narrow teams each of which carry different data traffic. Inter-beam interference is addressed by the application of Adaptive Modulation and Coding and by an inter-beam handoff scheme. The handoff scheme ensures that when an end user equipment is located in a cusp region between adjacent beams the antenna arrangement simultaneously transmits data traffic to that mobile station on at least both of the adjacent beams.

An apparatus includes a processor and a memory coupled to the processor. The memory stores instructions executable by the processor to perform operations that include determining power information indicative of total power of a designated number of channelization codes. Determining the power information comprises scaling a power offset value based on a number of available channelization codes and the designated number of channelization codes. The operations also include sending the power information to user equipment (UE). The operations further include determining a particular number of transport blocks and determining a distinct channel quality indicator (CQI) index of each of the transport blocks based on a CQI value received from the UE.

Certain aspects of the present disclosure generally relate to wireless communications, and more specifically increasing user capacity through a frame structure which supports eMTC UL multi-user multiplexing. According to aspects, a UE may identify at least one narrowband region within a wider system bandwidth, determine at least one parameter assigned to the UE for transmitting symbols of a physical uplink channel in the narrowband region that are multiplexed with symbols transmitted by one or more other UEs, and transmit the physical uplink channel using the at least one determined parameter.

An automotive Ethernet physical-layer (PHY) transceiver includes an Analog Front End (AFE) and a digital processor. The AFE is coupled via a full-duplex Ethernet link to a peer transceiver. The AFE is configured to receive from the peer transceiver, over the full-duplex Ethernet link, an analog Ethernet signal conveying data symbols, at a reception data rate that is lower than a transmission data rate used in transmitting data from the PHY transceiver to the peer transceiver, the Ethernet signal being modulated by a spreading sequence having a Spreading Factor including a ratio between a spreading chip-rate and the reception data rate, and to convert the received analog Ethernet signal into a digital signal. The digital processor is configured to de-spread the digital signal using the spreading sequence to recover the data symbols.

An internet of things (IoT) non-terrestrial network (NTN) device user equipment (UE) is described. The UE includes receiving circuitry configured to receive narrowband physical random access channel (NPRACH) configurations including NPRACH resource configuration, repetition parameters, orthogonal cover code (OCC) multiplexing methods and OCC multiplexing factors. The UE also includes transmitting circuitry configured to select an NPRACH resource and randomly select an OCC index for an OCC multiplexing. The transmitting circuitry is further configured to transmit NPRACH preambles with a configured OCC multiplexing method and a multiplexing factor.

Methods, systems, and devices for wireless communications are described. A UE may transmit one or more uplink messages according to an orthogonal cover code (OCC) and an OCC scheme indicated by a network entity. The UE may receive control signaling scheduling one or more uplink messages for transmission. The control signaling may also indicate one or more OCC parameters for the one or more uplink messages. The UE may receive second control signaling that indicates that an OCC scheme for uplink messages is enabled. The control signaling may indicate a row within a time domain resource allocation (TDRA) table or a row within an OCC table. In either case, the row may correspond to the one or more OCC parameters. The UE may transmit the one or more uplink messages using an OCC in accordance with the one or more OCC parameters, the OCC scheme, or both.
