[0017] Detailed Description Certain features are described using an example of a fifth generation (5G) wireless protocol. However, the applicability of the disclosed techniques is not limited to only 5G wireless systems. Headings are used in the following description only to aid understanding, without limiting the features described.

[0018] In 5G New Radio (NR), besides digital beamforming, analog beamforming is introduced into mobile networks to provide robustness of communication at high frequencies above 6 GHz. However, directional radio frequency (RF) transmission using analog beamforming techniques has limited multipath diversity, which makes communication above 6 GHz vulnerable to channel variations, e.g., human or vehicular obstruction. The link recovery procedure (also referred to as beam recovery procedure) enables a wireless device (also referred to as UE herein) to initialize one-event-based reporting of beam failure events and identify a new beam for subsequent data transmission. Link recovery may include the following steps: a) beam failure detection; b) new candidate beam identification; c) beam failure recovery request (BFR) (also referred to as link failure recovery request) from the UE to the next generation Node B (gNB); and d) gNB response regarding recovery. The procedure can be configured for a primary cell (PCell) or a primary secondary cell (PSCell), both of which are configured with an uplink (UL) channel to carry the step c link recovery request (i.e., the physical random access channel (PRACH)). In this specification, unless otherwise specified, a "PCell" is equivalent to a primary cell or a primary cell within a corresponding group of cells, e.g., a PSCell.

[0019] For secondary cells (SCells), a MAC-CE+PUCCH-BFR procedure is further introduced for that case. Compared with PCells, the link recovery procedure also includes four steps: a) beam failure detection, b) new candidate beam identification, c) beam failure recovery request (BFR) from UE to gNB, and d) gNB response regarding recovery. However, the BFR procedure is further divided into two sub-steps: requesting uplink shared channel (UL-SCH) resources through PUCCH-BFR signaling and reporting the failed CC index (corresponding to the failed SCell) and the associated new candidate beam index.

[0020] Current 5G NR solutions are based on a scenario where there is only a single panel on the UE side, which means that only one DL transmission beam can be received or only one UL transmission beam can be transmitted at a given time. In other words, if the UE has multiple panels, the activation or deactivation of the UE panel is entirely up to the UE implementation. However, this architecture of beam management has serious limitations on the transmission performance and power savings on the UE side when the UE actually has multiple panels.

[0021] In terms of transmission performance (regardless of DL transmission and UL transmission), simultaneous multi-beam transmission using multiple panels can support higher RANK transmission and obtain more spatial diversity gain, which means that channel capacity can be significantly improved.

[0022] In terms of UE power savings or maximum power exposure (MPE), due to the lack of UE preference for panel state (such as idle or active) and measurement results for each of the panels, when the UL beams of the panels are configured for dynamic indication by the gNB, a low-performing panel may be active all the time.

[0023] Conventional link recovery procedures are not suitable for the case of multi-panel operation (e.g., only a portion of the panels suffer from beam obstruction). The disclosed techniques, including UE-initiated DL simultaneous transmission mode and UL panel switching procedures, solve this problem.

[0024] The triggering event, the format of the UE report, the signaling of the gNB response, and the default UE behavior after the gNB response should be fully considered. As a UE initialization procedure, UL resources need to be reserved for this and the corresponding UE behavior during this procedure should be clearly specified.

[0025] Considering the case of CC groups and multiple TRPs, the scope or conditions for the UE initialization procedure, e.g. trigger events or steps for updating default beam and UL transmission resources, should be thoroughly investigated for part of a CC group or a single TRP out of multiple TRPs once the procedure has been successfully completed.

[0026] To support backward and forward compatibility, the UE capability to support this procedure and enable signaling from the gNB should be considered, as well as the timeline for applying the new identified beams or panels.

[0027] At the expense of wide or ultra-wide spectrum resources, the considerable propagation loss induced by the extremely high frequency becomes a prominent challenge. To solve this, antenna arrays and beamforming training techniques using massive MIMO, for example, up to 1,024 antenna elements for one node, are adopted to achieve beam matching and obtain sufficiently high antenna gain. In order to still benefit from antenna arrays while keeping low implementation costs, analog phase shifters become very attractive for implementing mm-wave beamforming, which means that the number of controllable phases is finite and certain modulus constraints are imposed on these antenna elements. Given a predefined beam pattern, variable phase shift-based BF training generally targets identifying the best pattern for subsequent data transmission in the case of a single TRP and a single panel.

[0028] To ensure robustness, the UE may initialize one link recovery procedure in the PCell, as shown in Figure 1, where the link recovery request transmission is based on the PRACH. In the PCell, the detailed procedure for contention-free based link recovery is summarized as follows:

[0029] Beam failure detection: One or more DL RSs are configured or implicitly derived for beam failure detection, and the corresponding BLER result (as a metric for beam failure detection) is determined through the step of measuring one or more DL RSs. When the BLER of all or a part of DL RSs is not worse than a predefined threshold in a configured window, an indication of link failure is notified to the MAC-CE layer. At the MAC-CE layer, if an indication of link failure is received from the PHY layer, the UE shall increment a counter for beam failure indication, i.e., BFI_COUNTER, by one, and a beam failure event is declared when BFI_COUNTER is equal to or greater than a preconfigured threshold.

[0030] New candidate beam identification: One or more DL RSs are configured as candidate RSs for new candidate beam identification. If the L1-RSRP result (as a metric for new beam identification) associated with one DL RS is not worse than a predefined threshold, then a single DL RS can be assumed as one new candidate beam, i.e., q_new.

[0031] Beam Failure Recovery Request (BFR): When a beam failure event is declared and / or at least one new candidate beam is found, the UE initiates one PRACH transmission associated with the selected RS q_new from step b (when the channel quality of any DL RS as a candidate beam for recovery is all worse than the threshold, the DL RS is selected). Any one of the DL RSs may be selected randomly), and each DL RS for new beam identification is associated with one or more PRACH opportunities.

[0032] gNB Response on Recovery: After sending a PRACH transmission for link recovery request, the UE should monitor one dedicated CORESET or PDCCH in a dedicated search space for link recovery according to the quasi-co-location parameters associated with DL RS q_new. Once a gNB response is detected, the UE should assume that the gNB response on recovery is successfully received and corresponding UE behavior, e.g., updating the QCL assumptions for one or more CORESETs and spatial filters of PUCCH resources, is performed.

[0033] Then, for the secondary cell (SCell), a MAC-CE+PUCCH-BFR procedure as a link recovery request is further introduced to replace the PRACH-based one. Compared with the PCell, the link recovery procedure also includes the above four steps. However, the BFR procedure, i.e., the link recovery request, is further divided into two sub-steps: requesting uplink shared channel (UL-SCH) resources through PUCCH-BFR signaling, and reporting the failed CC index (corresponding to the failed SCell) and the associated new candidate beam index.

[0034] Generally, the case of multi-TRP and multi-panel should be considered for gNB (base station) and next generation communication beyond 5G, while there are multiple panels for UE to cover the whole space to improve coverage. Figure 2A shows an example of beam measurement and reporting where the UE side has four panels. As a typical case, the panel for TRP and UE side has two TXRUs associated with cross-polarization accordingly. Therefore, in order to achieve high RANK or multi-layer transmission, the TRP and UE should try to use different beams generated from different panels with the purpose of fully using the capabilities of each panel, such as its associated TXRU, which is also called simultaneous transmission across multiple panels (ST x MP).

[0035] Furthermore, several CCs may be grouped into sets and DL and UL beam management may be performed together using integrated signaling, e.g., a single command may update the TCI beam / beam pool for PDCCH / CORESET, PDSCH, or SRS across multiple CCs.

[0036] As used herein, a "beam" is equivalent to a quasi-collocation (QCL) state, a transmission configuration indicator (TCI) state, a spatial relationship state (also called a spatial relationship information state), a reference signal (RS), a spatial filter, or a precoding.

[0058] As a UE event based procedure for updating the DL simultaneous transmission and UL active panel, aspects regarding the trigger event, the format of the UE report, the gNB response, and the default UE behavior after the gNB response should be specified.

[0059] Step 1: Regarding trigger events, at least one of the following should be supported:

[0060] Step 1a: TRP / Panel Specific Beam Fault Detection or Panel Switching Detection

[0061] For the first DL RS or the first group information (eg, corresponding to the current or old link for PDCCH), the following applies:

[0062] A channel quality, for example, a block error ratio (BLER), an uplink duty cycle, or a maximum power reduction (MPR), corresponding to the first DL RS or the first group information, is greater than or equal to a threshold value.

[0063] A channel quality, eg, a path loss, RSRP, or CQI, corresponding to the first DL RS or the first group information is lower than or equal to a threshold value.

[0064] The above events correspond to a panel, a CC / BWP in a CC / BWP group, or a CORESET in a CORESET pool.

[0065] Furthermore, the mapping between the first DL RS and the first group information is changed, in other words, the channel quality based on the first DL RS and the first group information is worse than or equal to a threshold value.

[0066] Step 1b: New candidate beam / panel identification

[0067] Regarding the second DL RS (corresponding to the new link) or the second group information:

[0069] The channel quality, eg, path loss, RSRP, or CQI, is higher than or equal to a threshold value.

[0070] The first and second DL RSs correspond to the same group information, the same CC / BWP in a CC / BWP group, or the same CORESET pool.

[0071] Furthermore, the channel quality based on the second DL RS and the second group information is better than or equal to a threshold value.

[0072] Moreover, the event condition further includes a channel quality based on the first DL RS and the first group information being worse than a channel quality based on the second DL RS and the second group information.

[0073] Moreover, the event condition further includes a channel quality based on the first DL RS and the first group information being worse than a channel quality based on the second DL RS and the second group information and an offset, wherein the offset is configurable.

[0074] Additionally, the channel quality corresponds to the change in the channel quality, for example the change since the last report.

[0075] Step 2: UE reporting procedure, e.g., reporting format

[0076] The second DL RS (corresponding to the new link as for new candidate beam / panel identification), second group information, CC or CC group, channel quality (e.g., MPR, RSRP, CQI), or CORESET pool are carried in the report format.

[0077] The reporting may be done via PUCCH, UCI (eg, as RSRP, SINR, or CSI reporting), or MAC-CE (eg, MPR or PHR reporting).

[0078] The second DL RS or the corresponding channel quality is associated with a second group information, a CC, a CC group, or a CORESET pool.

[0079] Furthermore, a channel quality of the second DL RS is received according to the constellation information.

[0080] Furthermore, a second DL RS may be applied for a CC, a group of CCs, or a CORESET pool.

[0081] Step 3: gNB response procedure, e.g., gNB response signaling

[0082] Further, the signaling can be a DCI or a MAC-CE command to confirm a UE report, e.g., to switch the simultaneous transmission mode or the active UL panel for transmission.

[0083] Furthermore, the signaling can be at least one of the following:

[0084] #1 PDCCH or DCI with dedicated RNTI for procedure

[0085] #2 PDCCH or DCI in the control resource set (CORESET) or search space for the procedure

[0086] #3 Procedure and associated DCI codepoint

[0087] #4 Indication of new data for the PUSCH carrying the report, e.g., toggled new data indication

[0088] Further condition: the indication for new data is associated with the same HARQ process number as the PUSCH carrying the report.

[0089] #5 Reconfiguration or activation of a TCI associated with a PDCCH, or reconfiguration or activation of a spatial relationship associated with a PUCCH.

[0090] Step 4: Default UE behavior after gNB response

[0091] At least one of the following is supported:

[0092] A mapping between the second DL RS and the second group information is applied.

[0093] A DL signal is received according to a QCL hypothesis corresponding to a second DL RS.

[0094] Furthermore, the DL signal and the second DL RS are associated with the same CC / BWP, the same group of CC / BWPs, or the same CORESET pool.

[0095] Furthermore, the DL signal and the second DL RS are associated with the same group information, for example, a UE panel.

[0096] The UL signal is transmitted according to a spatial relationship corresponding to the second DL RS or according to the second DL RS as the path loss RS.

[0097] Furthermore, the UL signal and the second UL RS are associated with the same CC / BWP, the same group of CC / BWPs, or the same CORESET pool.

[0098] Furthermore, the UL signal and the second UL RS are associated with the same group information, for example, a UE panel.

[0099] The second DL RS may be applied to a CC / BWP, or a group of CC / BWPs, or a CORESET pool corresponding to the first DL RS.

[0100] Furthermore, when a CC is reported in step 2, the second DL RS or the second group information is applied to all CCs in the CC group that includes the CC.

[0101] Note that step 1 may not always be necessary, and in some cases, alternatively, steps 2-4 below are controlled solely by the gNB, e.g., the procedure of step 2 of UE reporting is controlled and initialized by the gNB (e.g., periodic or aperiodic beam or panel reporting), and the corresponding steps 3 and 4 are performed accordingly (e.g., based on the reporting result of step 2).

[0102] In FIG. 2B is an example of UE initialization reporting considering UE rotation. FIG. 2B shows the same DL transmission beam but different UE DL receiving beam for transmission under UE rotation. Initially, data link transmission for link-1 and data link transmission for link-2 can be received simultaneously through two independent UE panels. However, after a certain period, UE rotation occurs and corresponding link-1 and link-2 are shared with the same UE panel, which means that the UE cannot receive link-1 and link-2 simultaneously. It should be noted that from the gNB's perspective, the gNB transmission beam is kept unchanged. In terms of trigger conditions, the channel quality of data transmission based on UE panel-1 is worse than that of data transmission based on UE panel-2. As a result, the mapping between DL RS and group information (e.g., UE panel) can be reported to the gNB according to the event of mapping change. Second embodiment: Procedure for UE initiated DL simultaneous transmission switching

[0103] For UE-initialized DL simultaneous transmission, the UE can support simultaneous reception mode through the step of using two or more independent UE panels. After receiving a UE capability report supporting this simultaneous mode, the gNB can configure enable signaling of DL channels with two or more different TCI / QCL states or receive two independent DL channels simultaneously. Also, group information indications for updating DL and / or UL transmission should be taken into account according to the UE-initialized report. An example can be found in FIG. 3.

[0104] Within the measurement window, no panel restrictions or mapping between DL RSs and panels are applied, so that the UE can find the best mapping between DL RSs and panels, for example with the objective of maximizing the RSRP, which means that during this period, a non-simultaneous reception mode is implemented by the UE.

[0105] After the measurement window, the UE should switch from non-concurrent reception to concurrent reception mode, but due to the absence of reporting and gNB response, the UE should perform a prior mapping between DL RS and group information.

[0106] Then, group-based reporting is initialized by the UE to provide one or more DL RSs and corresponding group information, which means that a new mapping between DL RSs and group information is provided.

[0107] Once a gNB response regarding the new report is received, the new mapping between DL RS and group information is applied accordingly. Third embodiment: Procedure for UE reporting driven by MPE events

[0108] To prevent from radio power considering human health, MPE requirement should be met according to the local law or regulation. More specifically, an additional MPR (also called P-MPE) is further applied for the maximum transmission power of UL transmission. It means that even if the UE can support stronger transmission power, the UE needs to reduce the maximum transmission power due to MPE effect. An example can be found in FIG. 4, where there is a strong MPE effect on link-2.

[0109] Regarding trigger events, at least one of the following should be supported:

[0110] For the first DL RS or the first group information, the corresponding maximum power reduction (MPR) or uplink duty cycle is higher than or equal to the threshold value.

[0111] For a second DL RS or second panel, the corresponding RSRP minus the MRP associated with the second DL RS or second panel is greater than or equal to the threshold value.

[0112] The first and second DL RSs correspond to the same group information, the same CC / BWP in a CC / BWP group, or the same CORESET pool.

[0113] UE Report Format

[0114] The second DL RS, the second group information, and the channel quality (eg, MPR and RSRP) are reported in a report format.

[0115] The report is conveyed by the MAC-CE for the MPR or PHR procedure.

[0116] When the MAC-CE is for PHR reporting, the PHR result is determined according to the second DL RS and / or the second group information.

[0117] Signaling the gNB response

[0118] Furthermore, the signaling may be an indication regarding new data (in the received HARQ information) for which a PUSCH carrying the report is received. Further condition: the indication regarding new data is associated with the same HARQ process number.

[0119] As default UE behavior after the gNB response, at least one of the following applies:

[0120] A mapping between the second DL RS and the second group information is applied.

[0121] A DL signal (eg, a PDCCH or a PDSCH) is received according to a QCL hypothesis corresponding to a second DL RS or a second group information.

[0122] A UL signal (eg, a PUCCH or a PUSCH) is transmitted according to a spatial relationship and a path loss corresponding to the second DL RS or the second group information.

[0123] The second DL RS may be applied to a CC / BWP, or a group of CC / BWPs, or a CORESET pool corresponding to the first DL RS.

[0124] As a result, after receiving the UE report, the DL RS and group information corresponding to link 3, and the gNB response, the UL and DL transmission corresponding to panel-2 are updated to the DL RS and group information corresponding to link 3. Fourth Example: UE Behavior after Receiving a gNB Response

[0125] Once the gNB response is received, the UE request from the report should be applied accordingly, except that according to the step of decoding the command in the gNB response, the end or start event for the mapping between the panel and the DL RS should be made clear.

[0126] The duration during which the gNB assumes that there will be no changes until the next gNB confirmation or report from the UE.

[0127] There are new measurement limits to initialize the remapping between any panel and DL RS.

[0128] The mapping between DL RS and UE panel should be updated every X time units after a new measurement.

[0129] This can be assumed as group-based reporting, with a flag configured by the gNB.

[0130] If the flag is configured to enable a new mapping between DL RS and group information, the group information should be reported, otherwise the group information is not reported.

[0131] The mapping between DL RS and group information applies up to the time unit corresponding to the next group-based report and applicable timing, subject to UE capabilities.

[0132] There are new indications from the gNB side confirming updated panel mapping or herd-based reporting.
