I. Introduction

Channel state information (CSI) report in the current new radio (NR) system can assist the network to provide a better transmission configuration to a UE. A CSI report can be configured to be aperiodic, semi-persistent or periodic. In such methods, the UE can report all the information associated with the reference signals configured for CSI report, which results in a large report overhead and report latency. In order to address this technical problem, UE-initiated beam report (UEIBR) is introduced to reduce report overhead and latency, i.e., a UE is initiated or triggered by itself to transmit a beam report when a condition related to a trigger event is fulfilled, where the trigger event is associated with the beam report. In order to inform NW that UE would transmit a beam report initiated by UE, UE should firstly transmits a message of UE-initiated beam report notification (UEIBRN) to NW, and then NW can realize the transmission of the UEIBR.

Uplink control information (UCI) types include HARQ-ACK information, scheduling request (SR) , link recovery request (LRR) , and CSI. UCI bits include HARQ-ACK information bits, if any, SR information bits, if any, LRR information bit, if any, and CSI bits, if any. Normally SR is applicable for SR and/or for LRR in NR systems. UE can be configured or scheduled by network device uplink resource (s) to carry UCI bits.

When a PUCCH overlaps another PUCCH or a PUSCH and the multiplexing conditions are satisfied, UE multiplexes UCI bits from a PUCCH in another PUCCH or the PUSCH, and transmits the bits after multiplexing in the another PUCCH or the PUSCH. The PUCCH will be dropped by the UE.

In this patent document, a UE-initiated beam report notification (UEIBRN) may include a SR associated with a UEIBR or a type of UCI for notification of a UEIBR.

In this patent document, a reference signal may include a SSB or a CSI-RS.

In this patent document, an uplink channel may include a PUSCH or a PUCCH.

In this patent document, a cell may include a serving cell, a physical cell, a candidate cell, a neighbor cell or a carrier component.

In this patent document, UE can transmit one or more uplink control information on corresponding one or more uplink channel resources, and UE can perform collision handling when the one or more uplink resources are overlapped in time domain or when the one or more uplink channel transmission overlap with a second uplink channel transmission, where at least one of the one or more uplink control information may include a UEIBR or a UEIBRN.

II. (a) . Example Embodiment 1

Example embodiment 1 specifies techniques for a UE transmitting a PUCCH carrying a UEIBRN.

In some embodiments, a UE receives a scheduling request resource configuration that configures the UE to transmit a PUCCH carrying a UEIBRN, where the scheduling request resource configuration indicates a scheduling request resource index and a PUCCH resource index for the PUCCH transmission. A positive or negative UEIBRN is equivalent to a positive or negative SR respectively. A transmission of a positive UEIBRN by the UE indicates to the base station that the UE expects to transmit the UEIBR, and a transmission of a negative UEIBRN by the UE indicates to the base station that the UE may not transmit the UEIBR or the UEIBR transmission is absent. A transmission of a positive SR by the UE indicates to the base station that scheduling request is triggered by the UE, and a transmission of a negative SR by the UE indicates to the base station that the scheduling request is not triggered or the scheduling request is cancelled.

In some embodiments, a UE receives a configuration indicating a PUCCH resource index or a UEIBRN resource index so that the UE is configured to transmit a PUCCH carrying a UEIBRN on the resource indicated by the PUCCH resource index or the UEIBRN resource index.

In some embodiments, a UE is configured with a periodicity and an offset for a PUCCH transmission for carrying UEIBRN.

● If the periodicity is configured to be larger than one slot, UE determines transmission occasions (e.g., frame number, slot number) of the PUCCH or transmission occasions of the UEIBRN based on the periodicity and the offset.

● If the periodicity is configured to be one slot, UE determines every slot is a transmission occasion of the PUCCH or a transmission occasion of the UEIBRN. UE expect to be configured with a zero value of the offset.

● If the periodicity is configured to be smaller than one slot, UE determines a transmission occasion (e.g., start symbol index) of the PUCCH or a transmission occasion of the UEIBRN based on the periodicity.

In some embodiments, a UE transmits a UEIBRN in a PUCCH resource identified in the corresponding UEIBRN configuration received by the UE, where the UE transmits the UEIBRN when the UE determines to transmit (and transmits) a positive UEIBRN.

● For a positive UEIBRN transmitted on the PUCCH resource and the PUCCH resource comprises a PUCCH format 0, UE transmits the PUCCH by determining a cyclic shift value (e.g., α) based on a sequence cyclic shift value (e.g., m_cs) , where the sequence cyclic shift value is determined by UE based on the value indicted by the positive UEIBRN.

○ When the positive UEIBRN indicates a value of 0, the sequence cyclic shift value is determined to be 0.

○ When the positive UEIBRN indicates a value of 1, the sequence cyclic shift value is determined to be 6.

● For a positive UEIBRN transmitted on the PUCCH resource and the PUCCH resource comprises a PUCCH format 1, UE transmits the PUCCH by determining one bit (e.g., b (0) ) for sequence modulation of the PUCCH transmission.

○ The value of the one bit is determined to be 0, or

○ the value of the one bit is determined to be 1.

In some embodiments, UE transmits a UEIBRN in the PUCCH resource for corresponding UEIBRN, where the PUCCH resource is indicated as being associated with the corresponding UEIBRN in a configuration received by the UE.

● For a UEIBRN transmitted on the PUCCH resource and the PUCCH resource comprises a PUCCH format 0, UE transmits the PUCCH by determining a cyclic shift value (e.g., α) based on a sequence cyclic shift value (e.g., m_cs) , where the sequence cyclic shift value is determined by UE based on the value indicated by the UEIBRN.

○ When the UEIBRN is a negative UEIBRN or indicates a value of 0, the sequence cyclic shift value is determined to be 0.

○ When the UEIBRN is a positive UEIBRN or indicates a value of 1, the sequence cyclic shift value is determined to be 6.

● For a UEIBRN transmitted on the PUCCH resource and the PUCCH resource comprises a PUCCH format 1, UE transmits the PUCCH by determining one bit (e.g., b (0) ) for sequence modulation of the PUCCH transmission.

○ When the UEIBRN is a negative UEIBRN or indicates a value of 0, the value of the one bit is determined to be 0.

○ When the UEIBRN is a positive UEIBRN or indicates a value of 1, the value of the one bit is determined to be 1.
