Definitions
- Examples of the present disclosure relate to transmitting and receiving uplink control information (UCI) and/or a scheduling request (SR).
- UCI uplink control information
- SR scheduling request
- Next generation systems e.g. new radio, NR, or 5G
- NR new radio
- 5G Next generation systems
- the traffic pattern associated with many use cases is expected to consist of short or long bursts of data traffic with varying lengths of waiting period in between (herein called inactive state).
- inactive state e.g., inactive state
- both license assisted access and standalone unlicensed operation are to be supported in 3GPP.
- the procedure of PRACH transmission and/or SR transmission in unlicensed spectrum shall be investigated in 3GPP.
- NR-U NR in unlicensed spectrum
- LBT Listen Before Talk
- 3GPP has defined a study item on NR-based Access to Unlicensed Spectrum (also referred to as NR-U).
- LAA LTE License Assisted Access
- NR-U also needs to support Dual Connectivity (DC) and standalone scenarios, where the MAC procedures including RACH and scheduling procedure on unlicensed spectrum are subject to Listen Before Talk (LBT) failures.
- DC Dual Connectivity
- LBT Listen Before Talk
- DRS discovery reference signal
- PSS/SSS PSS/SSS
- PBCH PBCH
- CSI-RS control channel transmission
- PUCCH/PDCCH physical data channel
- PUSCH/PDSCH physical data channel
- uplink sounding reference signal such as SRS transmission
- the Radio Resource Management (RRM) procedures in NR-U may be similar to LAA, since NR-U may aim to reuse LAA/eLAA/feLAA technologies as much as possible to handle the coexistence between NR-U and other legacy Radio Access Technologies (RATs).
- RRM measurements and reports may use a special configuration procedure with respect to channel sensing and channel availability. For example, channel access/selection for LAA was an important aspect for co-existence with other RATs such as Wi-Fi, including using carriers that are congested with Wi-Fi traffic.
- a User Equipment may measure Reference Signal Received Power (RSRP) and Reference Signal Received Quality (RSRQ) of the downlink radio channel, and provide measurement reports to its serving eNB/gNB. However, these measurements don’t reflect the interference strength on the carrier. Another metric, Received Signal Strength Indicator (RSSI), can serve such a purpose.
- RSSI Received Signal Strength Indicator
- some reports of RSRP or RSRP may be blocked, either due to that the reference signal transmission (DRS) is blocked in the downlink or that the measurement report is blocked in the uplink.
- DRS reference signal transmission
- a RSSI measurement timing configuration includes a measurement duration (e.g. 1-5 ms) and a period between measurements (e.g. ⁇ 40, 80, 160, 320, 640 ⁇ ms).
- Listen-before-talk is designed for unlicensed spectrum co-existence with other RATs.
- a radio device applies a clear channel assessment (CCA) check (i.e. channel sensing) before any transmission.
- CCA clear channel assessment
- the transmitter performs energy detection (ED) over a time period compared to a certain threshold (ED threshold) in order to determine if a channel is idle (i.e. if occupation of the channel by another transmitter is not detected) .
- ED threshold energy detection
- the transmitter performs a random back-off within a contention window before next CCA attempt.
- ACK acknowledgement
- the transmitter must wait a short period after each busy CCA slot before doing back-off (since the back-off is a random time which may be zero).
- the transmitter is only allowed to perform transmission up to a maximum time duration (namely, the maximum channel occupancy time (MCOT)).
- MCOT maximum channel occupancy time
- a channel access priority based on the service type has been defined. For example, there are four LBT priority classes defined for differentiation of contention window sizes (CWS) and MCOT between services.
- PCell primary cell
- SCell secondary cell
- the SCell carrying PUCCH will be associated with a number of SCells and they together constitute one PUCCH cell group. So, in order to transmit a Scheduling Request (SR) to indicate new data to be transmitted on an SCell, the SR is transmitted on the cell on which the PUCCH has been configured in the PUCCH cell group to which the SCell belongs.
- SR Scheduling Request
- DC Dual Connectivity
- a UE can only be configured with one PUCCH SCell, i.e. the UE can support up to two PUCCH cell groups as shown in Figure 1 , which shows an example of configuration of PUCCH on a SCell with two PUCCH cell groups (CGs).
- Each cell group (PUCCH cell groups 1 and 2) includes four cells.
- the two cell groups are mutually exclusive and cross-carrier scheduling between cell groups (CGs) is not allowed.
- the PUCCH channel is in the PCell, while the other cell group contains a PUCCH SCell.
- the PUCCH channel for the other cell group is deployed in the PUCCH SCell.
- NR unlicensed access In the NR unlicensed access (NR-U) work item defined for 3GPP Rel-16, NR unlicensed operation needs to support both standalone and DC scenarios meaning that both RACH and PUCCH-SR signaling need to be transmitted over unlicensed spectrum cells, since a NR-U cell may operate as a primary cell.
