The present disclosure relates to methods for reporting channel state information. The present disclosure also provides mobile stations for performing these methods, and computer readable media the instructions of which cause the mobile station to perform the methods described herein. For this purpose, the mobile station receives a trigger message that triggers the reporting of channel state information for at least one of the plurality of downlink component carriers, the trigger message being received in a subframe n.sub.Trigger, and reports the triggered channel state information for the at least one of the plurality of downlink component carriers based on reference signals present on the at least one of the plurality of downlink component carriers, in a subframe n.sub.Report later than n.sub.Trigger. The received trigger message indicates that the reference signals are present in a subframe n.sub.RS on the at least one of the plurality of downlink component carriers, where n.sub.Triggern.sub.RS<n.sub.Report.

Certain aspects of the present disclosure provide techniques for techniques for providing sidelink feedback. Certain aspects provide a method for wireless communication by a first user equipment (UE). The method generally includes receiving, from a second UE, one or more sidelink data messages and transmitting, to the second UE, via a first sidelink feedback channel resource, a first feedback message comprising one or more feedback bits associated with the one or more sidelink data messages, wherein: the first sidelink feedback channel resource comprises a first partial interlace group of a first interlace group of resource blocks, and the first partial interlace group comprises at least two first resource blocks.

A method of transmission over multiple wireless channels in a multiple antenna system includes storing channel modulation matrices at a transmitter; receiving quantized channel state information at the transmitter from plural receivers; selecting a transmission modulation matrix using the quantized channel state information from the stored channel modulation matrices; and transmitting over the multiple channels to the plural receivers using the selected transmission modulation matrix. In another embodiment, the method includes storing, at one or more receivers, indexes of modulation matrices generated by a capacity enhancing algorithm; upon a selected one of the one or more receivers receiving a transmission from the transmitter, the selected receiver selecting a modulation matrix from the stored modulation matrices that optimizes transmission between the transmitter and the selected receiver; the selected receiver sending an index representing the selected modulation matrix; and receiving the index at the transmitter from the selected receiver.

Certain aspects of the present disclosure provide techniques for implicitly linking aperiodic channel state information (A-CSI) reports to CSI-reference signal (CSI-RS) resources. In an aspect, the UE may be instructed to report on specific CSI-RS resource(s) via explicit signaling in the UE grant. Other aspects disclose techniques for implicit CSI-RS resource selection by the UE that require fewer signaling resources. Instead of explicitly signaling CSI-RS resources to the UE, the UE may implicitly select CSI-RS resource for CSI feedback reporting based on information known to the UE, e.g. a subframe on which a reporting request is received. This may reduce the impact of the additional signaling in the UE grant.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may identify, when using carrier aggregation and a plurality of component carrier groups, first traffic associated with a first service type and second traffic associated with a second service type for concurrent transmission. The user equipment may transmit, concurrently, the first traffic associated with the first service type using a first component carrier group of the plurality of component carrier groups, and the second traffic associated with the second service type using a second component carrier group of the plurality of component carrier groups. Numerous other aspects are provided.

System and method embodiments are provided for adaptive pilot allocation. In an embodiment, a method in a communication controller for adaptive pilot allocation includes determining at least one channel condition parameter for a wireless channel between the communications controller and a user equipment (UE). The method includes selecting a microframe pilot pattern to use for subsequent communications on the wireless channel according to the at least one channel condition parameter. Additionally, the method includes signaling an indication of the selected microframe pilot pattern to the user equipment. The method further includes transmitting data to the UE using the selected microframe pilot pattern.

A wireless device and a method therein for performing one or more operations based on available energy. The wireless device is configured to operate in a wireless communications network. Based on an amount of energy available for operation and based on control information, the wireless device determines an allocation of the amount of available energy between at least a first energy part and a second energy part. The first energy part is to be used in a sensing operation using a sensing operation configuration and the second energy part is to be used in a communicating operation using a communicating operation configuration. The wireless device performs based on the determined allocation, one or more operations out of: the sensing operation using the first energy part and the sensing operation configuration, and the communicating operation using the second energy part and the communicating operation configuration.

A method for a user equipment (UE) is disclosed. The method includes receiving, by the UE, downlink control information (DCI) for a downlink (DL) scheduling assignment (DL-DCI), the DL-DCI indicating a first uplink (UL) carrier associated with a Physical Uplink Control Channel (PUCCH) resource configuration for transmitting an aperiodic UL transmission for uplink control information (UCI), and transmitting, by the UE, the aperiodic UL transmission for UCI in a second UL carrier without a PUCCH resource configuration, where the UE determines a resource allocation of the second UL carrier based on the DL-DCI. The DL-DCI includes at least one of: a UL/supplementary UL (SUL) carrier indicator, a Hybrid Automatic Repeat reQuest (HARQ)-ACK resource indicator (ARI), a sounding reference signal (SRS) request field, a HARQ timing indicator, or a channel station information (CSI) request.

This application provides a method for configuring a channel state information reporting band, a reporting method, and a corresponding apparatus. The method includes: determining a channel state information subband size based on a bandwidth part BWP; and determining, a quantity of channel state information subbands included in a channel state information reporting band, based on a carrier bandwidth CC bandwidth or the bandwidth part BWP bandwidth or a channel state information reference signal CSI-RS bandwidth, and the channel state information subband size. The method further includes: determining an actual quantity of resource blocks included in a starting subband and an actual quantity of resource blocks included in an ending subband in the channel state information subband. Implementation of this application makes configuration of a quantity and size of subbands in a CSI reporting band more flexible, and reduces complexity of terminal addressing.

The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The present disclosure provides a priority of CSI reporting in a mobile communication system, and provides a method in which a UE performs CSI reporting with high priority according to the priority. The method includes receiving channel state information (CSI) feedback configuration information from a base station; identifying a CSI reporting to be performed based on the CSI feedback configuration information, as a result of two CSI reportings overlapping; and performing the identified CSI reporting to the base station. The CSI reporting is identified based on types of CSI reportings, and a CSI reporting associated with a reference signal received power (RSRP) is prioritized over a CSI reporting that is not associated with the RSRP.
