A method for encoding or transmitting. In some embodiments, the method includes forming a set of one or more unpunctured codewords by coding a plurality of payload bits at a mother code rate, removing a plurality of punctured bits from the set of one or more unpunctured codewords to form a set of one or more punctured codewords, and transmitting the set of one or more punctured codewords. In some embodiments, the number of punctured bits exceeds a first threshold, or the number of punctured bits exceeds a second threshold.

A terminal according to an aspect of the present disclosure includes: a transmitting section that transmits a plurality of pieces of channel state information (CSI) in different occasions, the plurality of pieces of CSI corresponding to at least one channel measurement; and a control section that determines, in response to reception of information corresponding to at least one piece of CSI of the plurality of pieces of CSI, whether or not to perform retransmission of the at least one piece of CSI. With this configuration, reduction of reliability of CSI can be prevented while reducing increase of UL overhead.

Methods and apparatuses for adaptive subcarrier spacing in wireless communication networks are described. For example, the described aspects include transmitting, from the UE to a network entity, a first PRACH transmission with a first subcarrier spacing; determining, by the UE, that the first PRACH transmission to the network entity is not successful; and transmitting, from the UE, a second PRACH transmission with a second subcarrier spacing in response to determining that the first PRACH transmission is not successful, wherein the first subcarrier spacing is different from the second subcarrier spacing.

The invention relates to a control channel signal for use in a mobile communication system providing at least two different scheduling modes. Further the invention relates to a scheduling unit for generating the control channel signal and a base station comprising the scheduling unit. The invention also relates to the operation of a mobile station and a base station for implementing a scheduling mode using the control channel signal. In order to facilitate the use of different scheduling schemes for user data transmission while avoiding an additional flag for indicating the scheduling mode in the control signaling, the invention proposes the use of code points in existing control channel signal fields. Further, the invention proposes a specific scheduling mode for use in combination with the proposed control channel signal. According to this scheduling mode control channel information is only provided for retransmissions, while initial transmissions are decoded using blind detection.

A user equipment (UE) for channel state information (CSI) comprises receiving configuration information for K CSI reports, wherein the configuration information includes resource allocation information for an uplink control information (UCI) transmission that includes UCI comprising N UCI parts, calculating the K CSI reports and partitioning the K CSI reports into N parts, determining an available number of information bits (B1) for the UCI transmission according to the resource allocation information, determining a required number of information bits (B2) for the UCI transmission according to the calculated K CSI reports, determining whether the B2 exceeds the B1; and transmitting, to the BS over one slot of an uplink channel, a first part of the N UCI parts including a first of the N parts of the K CSI reports when the B2 exceeds the B1, wherein K and N are positive integers.

Channel state feedback is provided from a UE to a base station as a first, detailed or a second, less detailed type of channel state feedback information. Initially it is determined whether the UE has received an uplink grant from the base station or not. If the UE has received an uplink grant, a first type of channel state feedback information is transmitted to the base station on the granted resource. If, however, the UE has not received an uplink grant, a second type of channel state feedback information is transmitted to the base station. Different types of channel state feedback information enables a UE and an associated base station to use available resources more efficiently, when requesting for and delivering channel state feedback information.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a request to transmit a channel state information (CSI) report relating to a channel quality of a target time interval. The UE may receive a plurality of CSI reference signals associated with the CSI report. The UE may determine respective CSI parts for one or more sub-time intervals of the target time interval based at least in part on the plurality of CSI reference signals. The UE may prioritize one or more of the CSI parts based at least in part on respective time indices associated with the one or more sub-time intervals. The UE may transmit a subset of the CSI parts based at least in part on prioritizing the CSI parts. Numerous other aspects are provided.

Systems, methods, apparatuses, and computer program products for channel state information (CSI) configuration and reporting for multi-transmission reception point (TRP) operation are provided. One method may include configuring a user equipment (UE), by a network node, to provide independent channel state information (CSI) feedback per transmission reception point (TRP) and to indicate additional information. The configuring of the UE may include configuring the UE with at least one of several reporting options for generating a combined channel state information (CSI) report.

Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a UE may measure a first reference signal, associated with a frequency band of a long term evolution (LTE) system, and a second reference signal associated with a frequency band of a new radio (NR) system. The frequency band of the NR system may overlap the frequency band of the LTE system. The UE may determine first channel state feedback, associated with the frequency band of the LTE system, and second channel state feedback, associated with the frequency band of the NR system, based at least in part on the first reference signal and the second reference signal, respectively. The UE may report the first channel state feedback or the second channel state feedback in uplink control information (UCI). Other aspects are provided.

Methods and apparatus to report link quality measurements for downlink dual carrier operation are disclosed. Example methods and apparatus disclosed herein implement one or more example techniques for reporting link quality measurements involving, for example, modifying measurement reporting messages to increase the number and/or types of link quality measurements that can be reported, permitting mobile stations, when appropriate, to use different reporting messages capable of supporting more link quality measurements, and/or prioritizing certain link quality measurements to be reported when the reporting messages do not contain sufficient space to report all requested and/or specified link quality measurements.
