detailed description

It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.

At present, with the sudden increase of services, it has become very necessary to quickly activate the secondary cell (Scell). By quickly activating the Scell, it can quickly respond to service requirements, improve user experience, and meet the needs of the fifth generation mobile communication network (5th generation mobile communication network). networks, 5G) network with a peak theoretical transfer speed of tens of GB per second.

For the rapid activation of Scell, the dormancy Bandwidth Part (dormancy BWP) scheme has been standardized in the R16 standard, and some enterprises and units have also proposed to optimize the Scell activation delay based on the Temporary reference signal (TRS). At present, the details of the scheme have not been disclosed too much, and the TRS scheme can be further discussed in the topic of Dynamic Spectrum Sharing (DSS) of the R17 standard protocol.

Among them, the Scell activation delay mainly includes the following two parts:

1. Activate the startup delay, that is, n-n+k;

2. Activation processing delay, n+k-n+M.

If the UE receives the Scell activation command on slot n, the UE officially starts the Scell activation process on slot n+k, and ends the Scell in the slot where the effective channel state information (CSI) is reported. Activation process.

where k refers to

k ₁ is used to indicate the location where the Hybrid Automatic Repeat Request (HARQ) feedback uplink control channel (Physical Uplink Control Channel, PUCCH) corresponding to the Physical Downlink Control channel (PDSCH) carrying the Scell activation command is located. slot. The calculation of the k value is based on the subcarrier spacing (SCS) where the PUCCH is located. Wherein k ₁ can correspond to the physical layer processing delay, which is 3ms->～1ms of long term evolution (Long Term Evolution, LTE), wherein, 3ms corresponds to the media access control (Media Access Control, MAC) layer processing delay and the radio frequency (Radio Frequency, RF) warm-up delay, from 4ms->3ms of LTE.

In TS 38.133 of the 3rd Generation Partnership Project (3GPP), it is stipulated in TS 38.133 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 means k ₁ , and T _{activation_time} means MAC - Delays in the analysis of CE signaling, RF warm up (warm up), automatic gain control (Automatic Gain Control, AGC) adjustment, and time-frequency offset synchronization. T _{CSI_reporting} indicates that the UE obtains the channel state information reference signal (channel state information). information reference signal, CSI-RS) delay, CSI-RS processing delay, and uncertainty delay of obtaining the first CSI report (report) resource, etc. The principle of the time for activating the Scell may refer to FIG. 1a.

At present, in the new radio (New Radio, NR) R-15, the minimum Scell activation delay is about 12ms, and the time for CSI acquisition is about 8ms. For example, Table 1 may refer to the parameter of the delay for activating the Scell.

Table 1

For the rapid activation of Scell, some enterprises and units have proposed the concept of dormant BWP. Dormant BWP can be understood as the UE does not need to blindly check the uplink grant (Uplink grant, UL grant) and downlink grant (Downlink) on the broadband part (Bandwidth, BWP). grant, DL grant), through primary cell (Primary Cell, Pcell) cross-carrier scheduling, the base station can only allow the UE to perform CSI measurement and measurement reporting. At this time, compared to the fact that the RF on the Scell is not turned off, it is equivalent to reducing the activation mentioned above. Processing delay part. In addition, the dormant BWP can be quickly switched to an activated BWP through the DCI-based BWP, which is equivalent to greatly reducing the activation startup delay part. In conclusion, the purpose of quickly activating the Scell can be achieved, and the standardization work has been carried out in the R16 standard protocol.

However, the method of using TRS is also proposed. Scell activation is still activated through MAC-CE signaling. By introducing TRS to optimize the AGC adjustment part of the T _{activation_time} delay, the Scell activation delay can also be effectively reduced, thereby quickly activating the Scell. However, the TRS scheme was further discussed under the topic of dynamic spectrum sharing (DSS) of the R17 standard, but was not discussed in depth in the R16 standard protocol, nor was relevant standardization work carried out. The TRS may be an Aperiodic Tracking Reference Signal (A-TRS), a semi-persistent channel state information reference signal (SP CSI-RS), an aperiodic channel state information reference signal Signal (Aperiodic channel state information reference signal, A-CSI-RS), semi-persistent tracking reference signal (semi-persistent tracking reference signal, SP TRS) and other reference signals.

The following two methods of activating Scell appear at the same time, but the details of the scheme are not disclosed too much.

(1): Independent Scell activation command and independent (reuse of existing) Reference RS activation mechanism;

(2): Combine the Reference RS and Scell activation commands into one command.

Among them, TRS is a special CSI-RS, which is used for channel tracking, and the UE performs precise time-frequency synchronization. The NR system supports periodic and aperiodic TRS. Periodic TRS is a CSI-RS resource set containing multiple periodic CSI-RS resources, and the resource set configuration includes a high-level signaling indicating that this resource set is used as TRS. The TRS has the same structure as the periodic TRS, such as the same bandwidth, the same frequency domain location and time slot, but the A-TRS in NR needs to be triggered by DCI, and currently it can only be triggered by UL Grant in the standard protocol.

In addition, the Media Access Control (MAC) layer is responsible for multiplexing multiple logical channels (Logic Channels) onto the same transport channel (transport channel). The Scell activation/deactivation MAC-CE signaling format is shown in the figure 1b and FIG. 1c, where C _i is used to indicate the activation/deactivation state of the Scell corresponding to the Scell index i, the C _i field is set to 1 to indicate 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, the structure of FIG. 1b is used. If there are more than 7 Scells, the structure of FIG. 1c is used. The corresponding logical channel identifiers (LCIDs) are 57 and 58 in Table 2, respectively. Wherein, Table 2 records the LCID value of the Downlink Shared Channel (Downlink Shared Channel, DL-SCH).
