[0049] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0050] With the sudden increase of business, it has become very necessary to quickly activate the secondary cell (Scell). By quickly activating the Scell, we can quickly respond to business needs, improve user experience, and meet the peak theoretical transmission speed of tens of GB per second of the fifth generation mobile communication network (5G).
[0051] In order to quickly activate Scell, the dormancy bandwidth part (dormancy BWP) solution was standardized in the R16 standard. Some companies and units also proposed a method to optimize the Scell activation delay based on the temporary reference signal (TRS). Currently, not many details of the solution have been disclosed. The TRS solution can be further discussed in the dynamic spectrum sharing (DSS) topic of the R17 standard protocol.
[0052] The Scell activation delay mainly includes the following two parts:
[0053] 1. Activation start delay, i.e. n-n+k;
[0054] 2. Activation processing delay, n+k-n+M.
[0055] If the UE receives the Scell activation command in slot n, the UE formally starts the Scell activation process in slot n+k, and ends the Scell activation process in the slot where valid channel state information (CSI) is reported.
[0056] Among them, k refers to k1 is used to indicate the slot where the hybrid automatic repeat request (HARQ) feedback uplink control channel (PUCCH) corresponding to the physical downlink control channel (PDSCH) carrying the Scell activation command is located. The calculation of the k value is based on the subcarrier spacing (SCS) where the PUCCH is located. Among them, k1 can correspond to the physical layer processing delay, from 3ms->~1ms of Long Term Evolution (LTE), among which 3ms corresponds to the media access control (MAC) layer processing delay and the radio frequency (RF) warm-up delay, from 4ms->3ms of LTE.
[0057] TS 38.133 of the 3rd Generation Partnership Project (3GPP) stipulates that the time for UE to activate Scell shall not be later than n+[T HARQ +T activation_time +T CSI_Reporting ], where T HARQ That means k1, T activation_time Indicates the delay of MAC-CE signaling analysis, RF warm-up, AGC adjustment, and time-frequency synchronization. CSI_reportingIndicates the delay of UE acquiring CSI-RS, CSI-RS processing delay and uncertainty delay of obtaining the first CSI report resource. The principle of activating Scell time can be referred to Figure 1a .
[0058] At present, in New Radio (NR) R-15, the minimum Scell activation delay is about 12 ms, of which the time for CSI acquisition is about 8 ms. For example, the parameters of the Scell activation delay can refer to Table 1.
[0059] Table 1
[0060]
[0061] In order to quickly activate Scell, some enterprises and organizations have proposed the concept of Dormant BWP. Dormant BWP can be understood as UE does not need to blindly check uplink grant (UL grant) and downlink grant (DL grant) on this BWP. Through cross-carrier scheduling of the primary cell (Pcell), the base station can only let the UE perform CSI measurement and measurement reporting. At this time, compared with the RF on the Scell not being turned off, it is equivalent to reducing the activation processing delay mentioned above. In addition, the dormant BWP can be quickly switched to an activated BWP through DCI-based BWP switching, which is equivalent to greatly reducing the activation startup delay. In summary, the purpose of quickly activating Scell can be achieved, and standardization work has been carried out in the R16 standard protocol.
[0062] However, a method using TRS is currently proposed. Scell activation is still activated through MAC-CE signaling. By introducing TRS to optimize T activation_time The AGC adjustment part of the delay can also effectively reduce the Scell activation delay, thereby achieving the purpose of quickly activating the Scell. However, it has not been discussed in depth in the R16 standard protocol, nor has it been standardized. The TRS solution has been further discussed under the dynamic spectrum sharing (DSS) topic of the R17 standard. Among them, TRS can be reference signals such as aperiodic tracking reference signal (A-TRS), semi-persistent, channel state information reference signal (SP CSI-RS), aperiodic channel state information reference signal (A-CSI-RS), and semi-persistent tracking reference signal (SPTRS).
[0063] The following two methods of activating Scell are also presented, but the details of the solutions are not disclosed in detail.
[0064] (1): Independent Scell activation command and independent (reusing existing) Reference RS activation mechanism;
[0065] (2) Combine the Reference RS and Scell activation commands into one command.
[0066] Among them, TRS is a special CSI-RS, which is used for channel tracking and accurate time and frequency synchronization of UE. The NR system supports periodic and non-periodic TRS. Periodic TRS is a CSI-RS resource set containing multiple periodic CSI-RS resources, and this resource set configuration contains a high-level signaling indicating that this resource set is used as TRS. Non-periodic TRS has the same structure as periodic TRS, such as using the same bandwidth, having the same frequency domain position and time slot, but A-TRS in NR needs to be triggered by DCI, and currently it can only be triggered by UL Grant in the standard protocol.
[0067] In addition, the MAC layer is responsible for multiplexing multiple logical channels (Logic Channel) onto the same transport channel (transport channel). The Scell activation and deactivation MAC-CE signaling format is as follows: Figure 1b and Figure 1c As shown, Ci is used to indicate the activation / deactivation status of the Scell corresponding to Scell index i. If the Ci field is set to 1, it indicates that the Scell is activated, otherwise it indicates that the Scell is deactivated, and R is a reserved bit. If the number of aggregated cells is less than 8, Scells are used Figure 1b If there are more than 7 Scells, use Figure 1c The corresponding logical channel identifiers (LCIDs) are 57 and 58 in Table 2. Table 2 records the LCID value of the downlink shared data signal (DL-SCH).

The method can be executed by a signaling processing device, the device can be implemented by software and / or hardware, the device can be configured in a first communication node, the first communication node can be a user terminal (User, Equipment, UE), and the method can be applied to the scene of activating a secondary cell (Secondary Cell, Scell), such as Figure 1d As shown, the technical solution provided in the embodiment of the present application includes the following steps:
[0071] S110: Receive at least one Media Access Control Control Element (MAC-CE) signaling.
[0072] S120: Determine at least one activated secondary cell Scell based on the MAC-CE signaling and trigger at least one temporary reference signal TRS for the activated Scell.

[0090] In an exemplary embodiment, when at least one MAC-CE signaling includes one first MAC-CE signaling and N second MAC-CE signalings, N activated Scells are determined based on one first MAC-CE signaling, and M A-TRSs for a corresponding Scell among the N activated Scells are determined based on each second MAC-CE signaling.

The structure of the MAC-CE signaling can refer to Figure 1i and Figure 1j .
[0096] Figure 2a is a flow chart of a signaling processing method provided in an embodiment of the present application. The method can be executed by a signaling processing device. The device can be implemented by software and / or hardware. The device can be configured in a first communication node. The first communication node can be a UE. The method can be applied to a scenario of activating a Scell, such as Figure 2a As shown, the technical solution provided in the embodiment of the present application includes the following steps:
[0097] S210: Receive downlink control information (Downlink Control Information, DCI).
[0098] S220: Determine an activated Scell based on the DCI and trigger a TRS for the activated Scell.
[0099] In an exemplary implementation, the triggering of the TRS for activating the Scell includes triggering a non-periodic triggering state or triggering a resource set.
[0100] The aperiodic trigger state includes at least a Resource set parameter selected from Resourcesetting; wherein the resource set includes at least a NZP CSI-RS Resource configuration parameter. The UE performs measurement based on the non-zero power channel state information reference signal (NZP CSI-RS) for automatic gain control AGC adjustment, etc., to reduce Scell activation delay.
[0101] In an exemplary embodiment, the TRS includes at least one of the following: a non-periodic tracking reference signal A-TRS, a non-periodic channel state information reference signal A-CSI-RS, and a semi-persistent tracking reference signal SP-TRS.
[0102] In an exemplary implementation, determining an activated Scell based on the DCI and triggering a TRS for the activated Scell includes:
[0103] Determine an activated Scell based on the indication information in the first indication field in the DCI;
[0104] Determine triggering of a TRS for activating the Scell based on the indication information in the second indication field in the DCI.
[0105] In an exemplary embodiment, the first indication field includes at least one of the following:
[0106] Scell dormancy indication field (Scell dormancy indication), carrier indicator field (Carrier indicator Field, CIF), re-interpretation bit field, new bit field.
[0107] Among them, the re-interpretation bit field can be at least one of the following: frequency domain resource allocation field, modulation and coding method field, new data indication field, redundant version field, HARQ process field, antenna port field, and demodulation reference signal (Demodulation reference signa, DMRS) sequence initialization field.
[0108] For example, according to the dormancy group within the RRC message activation time (Scell-groups-for-dormancy-within-active-time), the Scell dormancy indication field in the DCI is determined to be 5 bits. If the Scell dormancy indication field in the DCI is configured as 01010, it means that the Scells corresponding to Group2 and Group4 are activated; similarly, the CIF field, the reinterpretation bit field, or the newly added bit field indicates the activated Scell, where the above bit field can be indicated based on the group indication or based on a single Scell.
[0109] In an exemplary embodiment, the second indication field includes at least one of the following:
[0110] Channel state information request field, Scell sleep indication field, reinterpretation bit field, and new bit field.
[0111] The reinterpretation bit field may be at least one of the following: a frequency domain resource allocation field, a modulation and coding method field, a new data indication field, a redundancy version field, a HARQ process field, an antenna port field, and a DMRS sequence initialization field;
[0112] For example, the Scell sleep indication field may be reinterpreted to trigger the TRS; the newly added bit field may be an A-TRS request field.
[0113] In an exemplary implementation, the DCI includes: an uplink grant (UL Grant) DCI and / or a downlink grant (DL Grant) DCI.
[0114] In an exemplary implementation, before receiving the DCI, the method further includes:
[0115] Receive Radio Resource Control (RRC) messages.
[0116] In an exemplary embodiment, the RRC message includes at least one of the following:
[0117] R17-Scell activation indication (ScellActivation-r17), the dormant group within the activation time;
[0118] The R17-Scell activation indication is used to indicate that the Scell sleep indication field in the DCI is used for Scell activation / deactivation of the R17 standard protocol, or for Scell sleep indication of the R16 standard protocol.
[0119] In this embodiment, the R16 standard protocol already supports Scell Dormancy DCI, and the switching between the dormant BWP and the normal BWP on the Scell is realized by BWP switching, which can greatly reduce the activation delay of the Scell. If the TRS-based Scell activation scheme is introduced in the R17 standard protocol, it is necessary to add 1 bit in the RRC message (for example, the RRC message is defined as ScellActivation-r17). If the RRC message is set to 1, it means that the TRS-based Scell activation scheme is used, otherwise the ScellDormancy-based scheme in the R16 standard protocol is used; at the same time, if the TRS-based Scell activation scheme is adopted, the relevant indication field in the DCI is used to indicate the activation and deactivation of the Scell, which can be combined with the A-TRS request (request) field in the DCI (or the newly added bit field, because the DL Grant DCI itself does not have the A-TRS request field) to indicate which Scells are activated. Alternatively, the Scell Dormancy-related indication field in the DCI (which can be the Scell dormancy indication field) is used to indicate the A-TRS request, and the Scell activation is still based on the MAC-CE signaling.
[0120] The DCI may include UL Grant DCI (format 0-1) or DL Grant DCI (format 1-1).
[0121] The number of bits of the Scell dormancy indication is determined according to the higher-layer parameter Scell-groups-for-dormancy-within-active-time in the RRC message. Each bit corresponds to a Scell Group and is configured by the higher-layer parameter Scell-groups-for-dormancy-within-active-time in the RRC message.
