A communication system utilizing reconfigurable antenna systems is described where beam steering and null forming techniques are incorporated to limit the region or volume available for communication with client devices. The communication system described restricts communication to defined or desired area and degrades signal strength coverage outside of a prescribed region. An algorithm is used to control the antenna system to monitor and control antenna system performance across the service area. This antenna system technique is applicable for use in communication systems such as a Local Area Network (LAN), cellular communication network, and Machine to Machine (M2M).

The disclosure is related to a receiving device, a transmitting device, a communication method, and medium. The receiving device comprises processing circuitry configured to: receive a reference signal from a transmitting device, wherein the reference signal carries a reference sequence generated based on an orthogonal sequence and a random sequence associated with the transmitting device; and identify the transmitting device based on the reference signal.

A method for performing channel measurement for one or more subbands belonging to the entire system bandwidth, which is performed by a terminal, may comprise the steps of: receiving, from a base station, information on a window of channel measurement sections for N subbands for which the channel measurement is performed and information indicating a sub-frame in which channel measurement is to be performed in the window; performing channel measurement for K (N≧K) subbands in the window; and transmitting a result of the channel measurement to the base station, wherein the result of the channel measurement is transmitted to the base station in one subband belonging to the entire system bandwidth.

A wireless communication system that concurrently communicates information in multiple regulatory domains to facilitate audio/video media streaming and other high bandwidth operations. One domain may be licensed and the other may be unlicensed. Transmission in the licensed domain may occur in white space in the domain, and the amount of information transmitted in that domain may be limited by regulations. The amount of information conveyed in the licensed domain may also depend on channel conditions in either or both of the domains. As a result, the relative amount of information transmitted in each domain may vary dynamically. The system includes a transmitter that dynamically determines weighting coefficients applied to each of a plurality of channels to set power levels in both domains to achieve a desired metric for the overall communication. A corresponding receiver assembles the substreams into a stream that can then be displayed or otherwise processed.

Provided is a 5.sup.th generation (5G) or 6.sup.th generation (6G) communication system for supporting higher data rates after 4G communication systems such as long term evolution (LTE). A communication method of a user equipment (UE) includes receiving, from a base station (BS), information about a decoding mode including bit information corresponding to the number of times of perturbation, receiving data from the BS on a Physical Downlink Shared Channel (PDSCH), and decoding the received data based on the information about the decoding mode, wherein the information about the decoding mode may be generated based on service information including at least one of Quality of Service (QoS), a service priority, packet delay performance, packet error probability performance, a requirement, or a data transmission scheme.

Aspects described herein relate to requesting and/or reporting channel feedback. A request for channel feedback can be generated by an access point, where the request includes an indicator specifying that the request uses a first format different from a second format, where the indicator corresponds to a bit of a station (STA) information field defined by the second format. The access point can transmit, and a STA can receive, the request for channel feedback.

Aspects of the present invention provide apparatuses and methods for adaptive channel state feedback (CSF) estimation techniques. Downlink transmissions can be received at a mobile device. The downlink transmissions can be received after the mobile device has entered a power saving mode of operation. The downlink transmission received can be a discontinuous downlink subframe and can include one or more pilot symbols. A channel variation factor of the transmission channel can be determined based on the received downlink transmission. Based on the amount of variation of the transmission channel, either an earlier-received or a later-received pilot symbol can be used for CSF estimation. Further, either higher or lower weighted filter coefficients can be selected for use in CSF estimation based on the amount of variation of the transmission channel.

Disclosed are a parameter transmission method and apparatus, and a non-transitory computer-readable storage medium. The transmission parameter method includes: sending, by a sending end, control information carrying a value of at least one transmission parameter in at least one transmission parameter set; wherein the control information adopts a value of a transmission parameter for a slot or a link on which the control information acts.

A method, a computer-readable medium, and an apparatus are provided. The apparatus communicates with a second apparatus, including transmitting or receiving a first transmission. The apparatus receives information about the second UE from a sensor at the first UE and/or from a BSM. The apparatus determines whether the first apparatus and the second apparatus are in a LOS condition based on a correlation of the information with one or more of a channel estimation, PMI feedback, or RI feedback. The apparatus may adapt a transmission parameter for a second transmission based on a predicted location of the first apparatus or the second apparatus. The transmission parameter may include at least one of a modulation, a code rate, a DMRS density, a precoder, a CSI-RS transmission periodicity or a feedback rate.

Provided is a method of transmitting scheduling control information on a physical uplink shared channel by a base station. The method includes transmitting control information indicating a specific modulation and coding scheme (MCS) index corresponding to modulation and coding scheme (MCS) information to be applied to the physical uplink shared channel through a physical downlink control channel, and receiving the physical uplink shared channel modulated based on specific MCS information determined using one of two or more MCS tables containing the specific MCS index and modulation order information corresponding to at least the MCS index.
