A communication device in a communication network includes at least one processor. The at least one processor is configured to at least one processor configured to search a spectrum of the communication network using a Long Term Evolution Primary Synchronization/Secondary Synchronization Signals (LTE PSS/SSS), estimate the LTE interference using cell specific reference signals for Down Link (DL) when the LTE PSS/SSS signal is detected, and utilize LTE cell specific reference signals (CRS) and feed the equalized signal to a Data Over Cable Service Interface Specification (DOCSIS) Physical Layer (PHY) engine.

The present invention discloses an indication information transmission method and apparatus. The method includes: determining, in one or more codebooks, a first codebook used to send a first downlink data stream to a terminal device; determining one or more second codebooks used to send a second downlink data stream; determining codebook indication information used to indicate the first codebook and the one or more second codebooks; and sending the codebook indication information to the terminal device.

It is possible to improve the CQI reception performance even when a delay is caused in a propagation path, a transmission timing error is caused, or a residual interference is generated between cyclic shift amounts of different ZC sequences. For the second symbol and the sixth symbol of the ACK/NACK signal which are multiplexed by RS of CQI, (+, +) or (−, −) is applied to a partial sequence of the Walsh sequence. For RS of CQI transmitted from a mobile station, + is added as an RS phase of the second symbol and − is added as an RS phase of the sixth symbol. A base station (100) receives multiplexed signals of ACK/NACK signals and CQI signals transmitted from a plurality of mobile stations. An RS synthesis unit (119) performs synthesis by aligning the RS phase of CQI.

Methods, systems, and devices for wireless communications are described. Generally, a base station may configure one or more cross-link interference measurement resources on which a user equipment (UE) is to measure CLI. The UE may measure CLI from a single aggressor UE in multiple receive directions. The UE may identify receive beams on which it receives other signal types, and use those receive beams to measure CLI. In some examples, the base station may explicitly indicate to the UE which receive beams it is to use for CLI measurements. The UE may measure CLI on each CLI measurement resource using the identified receive beam, and may transmit, to the base station, a CLI report including CLI measurements, an indication of resource on which CLI measurements were taken, or a combination thereof.

The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and apparatus for receiving control information through an enhanced physical downlink control channel (EPDCCH), the method includes receiving a subframe which includes one or more EPDCCH physical resource block (PRB) sets, and attempting to decode one or more EPDCCH candidates in each of the EPDCCH PRB sets. When the transmission areas of the EPDCCH PRB set and a first signal overlap with each other, information relating to the EPDCCH candidate or information relating to the decoding is determined to be different according to one or both of EPDCCH PRB set type and/or cell identity (ID).

A method is provided for transmitting network assistance information in a serving cell in order to perform interference cancellation of a terminal. The serving cell checks whether a traffic load of the serving cell is greater than or less than a first value, and whether a traffic load of a neighbor cell is greater than or less than a second value. The serving cell determines a target for which the interference cancellation is to be performed by the terminal, based on a result of the checking the traffic load of the serving cell and a result of the checking the traffic load of the neighbor cell. The serving cell transmits to the terminal the network assistance information including information regarding the determined target for which the interference cancellation is to be performed.

Methods and systems for improving adjacent channel rejection performance in a wireless signal by a radio device in a mobile network. In one embodiment, a mobile radio network includes a first radio device (e.g., a subscriber), a second radio device, and a fixed radio apparatus (e.g., a base station or repeater). The first radio device receives a first channel signal having a first frequency offset with respect to a reference frequency. The first channel signal is associated with the second radio device. The first radio device measures the first frequency offset, determines a second frequency offset for a second channel signal, and transmits the second channel signal with the second frequency offset.

Various aspects of the present disclosure generally relate to wireless communications. In some aspects, a user equipment (UE) may transmit a wireless in-vehicle network (wIVN) capability indication that indicates that the UE is associated with a vehicle that includes a wIVN; receive a response to the wIVN capability indication from another UE; and provide configuration information to a wIVN control unit of the vehicle associated with configuring the wIVN based at least in part on the response. Numerous other aspects are provided.

Aspects of the subject disclosure may include, for example, receiving sounding reference signal (SRS) symbols from antenna elements of each of multiple modular antenna arrays, wherein the multiple modular antenna arrays are operatively combined to form a coherent antenna system, performing an uplink (UL) channel estimation and a downlink (DL) channel estimation, across a plurality of physical resource blocks (PRBs), based on the SRS symbols, calculating, for the antenna elements, a plurality of uplink (UL) combining weights based on the UL channel estimation and a plurality of downlink (DL) precoder weights based on the DL channel estimation, and causing the plurality of UL combining weights and the plurality of DL precoder weights to be applied to the antenna elements, thereby adjusting beamforming of the coherent antenna system. Other embodiments are disclosed.

Conventional filter bank multi-carrier (FBMC) wireless communication systems offer superior spectral properties compared to the cyclic-prefix orthogonal frequency-division multiplexing (CP-OFDM) approach, at the cost of an inherent shortcoming in dispersive channels called intrinsic imaginary interference. In this disclosure the DP-FBMC system was disclosed. A DP-FBMC based communication system uses two orthogonal polarizations for wireless communication systems: dual-polarization FBMC (DP-FBMC). The system significantly suppresses FBMC intrinsic interference. For the disclosed DP-FBMC all the multicarrier techniques used in CP-OFDM systems for channel equalization etc., are applicable without using complex processing methods that are required for conventional FBMC. Disclosed DP-FBMC also is more robust in multipath fading channels, and also to receiver carrier frequency offset (CFO) and Timing offset (TO). In the disclosed DP-FBMC system, three different structures may be used based on different multiplexing techniques.
