Apparatus for determining a coding rate
Provided is a communication device, which is enabled to improve the throughput of a communication system by reducing the difference of a transmission power between an SCCH and an SDCH thereby to satisfy the required quality of a PAPR. In this device, an MCS selection unit (111) of a transmission unit (110) decides, with reference to a CQI lookup table, an MCS pattern (MCS1) of the SDCH, an MCS pattern (MCS2) of the SCCH and information (multiplex information) on multiplex positions on the time axes of those two channels, on the basis of the CQI information. On the basis of the MCS2 and the MCS1, encoding modulation units (112 and 113) perform encoding and modulating operations. According to the multiplex information, a channel multiplexing unit (114) time-division multiplexes the SCCH and the SDCH thereby to generate a transmission signal.
Communication apparatus, control method, and storage medium
When a plurality of apparatuses each having a role of establishing a wireless network performs, in parallel, communication with a first apparatus having a role of joining a wireless network via a plurality of transmission channels, a communication apparatus controls, based on information about a communication quality in communication between a second apparatus included in the plurality of apparatuses and the first apparatus, a transmission output of at least the second apparatus such that a difference decreases between (i) communication quality in communication between an apparatus included in the plurality of apparatuses and different from the second apparatus and the first apparatus and (ii) a communication quality in communication between the second apparatus and the first apparatus. Alternatively, the communication apparatus determines at least one of a coding rate and a modulation scheme for use in communication between the second apparatus and the first apparatus based on the information.
Dynamic clear channel assessment
A first device determines a maximum allowable interference, and transmits a packet including an indicator of the maximum allowable interference. The maximum allowable interference corresponds to an amount of interference that can be present at the first device without preventing proper reception, by the first device, of packets from a second device, or to an amount of interference that can be present at the first device without resulting in a reduction in a Modulation and Coding Scheme of communications between the first and second device. A secondary transmitting device receives an indication of a maximum allowable interference, determines a maximum transmission power according to the maximum allowable interference, and transmits packets during a NAV protection period at a transmission power less than or equal to the maximum transmission power, when the NAV protection period does not reserve the medium the secondary transmitting device.
Techniques for managing power consumption of a mobile device
Systems, methods, apparatuses, and computer-readable storage media for managing power consumption of a mobile device are disclosed. The systems, method, apparatus, and computer-readable storage medium may cause the base station to identify an energy metric associated with a mobile device, and to configure the transmission between the base station and the mobile device based at least in part on the energy metric. The configuration of the transmission may reduce the power consumption of the mobile device for processing the transmission.
METHOD AND COMMUNICATION DEVICE FOR CONTROLLING INTER-LINK INTERFERENCE
A method implemented in a communication device for controlling inter-link interference due to transmissions from the communication device on a radio link to which different types of resources are allocated. The method comprises separately limiting transmission powers on the different types of resources by operating separate interference control instances. At least two of the separate interference control instances are based on the same group of schemes but adopt different scheme-related control parameters for at least one of the schemes or are based on different groups of schemes. The method further comprises performing transmissions on the different types of resources according to the separately limited transmission powers. Also provided is a communication device for controlling inter-link interference.
Techniques for uplink transmissions
Various aspects described herein relate to techniques for uplink transmissions in wireless communication systems. In an aspect, a method includes receiving, by a user equipment (UE), hopping information for two consecutive symbols, generating, by the UE, a first symbol of the two consecutive symbols using a format, generating, by the UE, a second symbol of the two consecutive symbols based on the format and the hopping information, and transmitting, by the UE, the two consecutive symbols in an uplink signal.
BASE STATION, USER EQUIPMENT, AND RADIO COMMUNICATION SYSTEM
For each UE, a base station determines the number of streams for transmitting a data signal, performs different precoding on the data signal depending on the UE, and allocates different transmission powers to at least two UEs. The base station transmits streams addressed to the at least two UEs in a form in which these streams are non-orthogonally mixed, with transmission powers that are different for the UEs. For each of the streams addressed to these UEs, the base station estimates predictive indices for these UEs from channel state information determined by the UEs to which those streams are addressed, and, based on the predictive indices, allocates different transmission powers to those UEs such that the better the predictive index is, the lower the transmission power is.
System and Method for Multi-user Full Duplex Link Adaptation
A method of link adaptation is described including establishing, using a first serving point, a multi-user full duplex mode wherein the multi-user full duplex mode enables a downlink to a first wireless device and an uplink from a second wireless device. The first serving point requests from the first wireless device a first channel quality indicator indicating channel quality between the serving point and the first wireless device in a full duplex time period and a second channel quality indicator indicating channel quality between the serving point and the first wireless device in non-full duplex time period. The full duplex mode is evaluated using the first and second channel quality indicators. At least one parameter of the full duplex mode is adjusted based on the evaluating.

An aspect of a terminal of the present disclosure includes a control section that determines a first modulation order applied in a first period and a second modulation order applied in a second period, based on different pieces of information, and a receiving section that receives a downlink channel, based on the first modulation order or the second modulation order.
POWER CONTROL FOR UPLINK COMMUNICATIONS IN FULL DUPLEX MODE
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a first power control parameter associated with a first uplink transmission from the UE, wherein the first power control parameter is based on at least one of: an adjusted target power for the first uplink transmission, an adjusted scaling factor for the first uplink transmission, a first parameter based at least in part on a self-interference associated with the UE, a second parameter based at least in part on a code rate or a modulation and coding scheme associated with a downlink transmission for the UE, or a combination thereof; and transmit, to a base station, the first uplink transmission based at least in part on the first power control parameter.
