Detailed Description

It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

At present, with the sudden increase of services, it has become necessary to rapidly activate a Secondary Cell (Scell), and by rapidly activating the Scell, service requirements can be rapidly responded, user experience is improved, and a peak theoretical transmission speed of tens of GB per second of a fifth generation mobile communication network (5th generation mobile networks, 5G) network is satisfied.

For fast activation of Scell, standardization work is performed on a scheme of a dormant broadband Part (dormant BWP) in the R16 standard, and some enterprises and organizations have also proposed a method for optimizing Scell activation delay based on a Temporary Reference Signal (TRS), which is not disclosed in detail at present, and the Dynamic Spectrum Sharing (DSS) subject of the R17 standard protocol may be further discussed on a TRS scheme.

The Scell activation delay (Scell activation delay) mainly includes the following 2 parts:

1. activating a start-up delay, i.e., n-n + k;

2. activation processing latency, n + k-n + M.

If the UE receives the Scell activation command in slot (slot) n, the UE formally starts the Scell activation procedure in slot n + k, and ends the Scell activation procedure in the slot where the effective Channel State Information (CSI) is reported.

Wherein k denotes

k1 is used to indicate Hybrid Automatic repeat request (HARQ) corresponding to Physical Downlink Control Channel (PDSCH) carrying Scell activation command, and to calculate slot k value of feedback uplink Control Channel (PUCCH) based on Subcarrier spacing (SCS) of PUCCH, where k1 may correspond to Physical layer processing delay, which is determined by 3ms->1ms, wherein 3ms corresponds to Media Access Control (MAC) layer processing delay and Radio Frequency (RF) preheating delay, and is replaced by 4ms of LTE>3ms。

The TS 38.133 in the third Generation Partnership Project (3 GPP) specifies that the UE should not activate Scell later than n + [ T ]_HARQ+T_{activation_time}+T_{CSI_Reporting}]Wherein T is_HARQI.e. k1, T_{activation_time}Represents the analysis time delay, RF up (arm up), AGC adjustment, time frequency deviation synchronization and other time delays, T, of the MAC-CE signaling_{CSI_reporting}And the time delay for acquiring the CSI-RS, the CSI-RS processing time delay, the uncertainty time delay for acquiring a first CSI report (report) resource and the like are represented by the UE. The principle of the time for activating the Scell can refer to fig. 1 a.

Currently, in a New Radio (NR) R-15, the minimum Scell activation delay is about 12ms, where the time for CSI acquisition is about 8 ms. For example, the parameters of the time delay for activating the Scell may refer to table 1.

TABLE 1

Aiming at rapidly activating the Scell, some enterprises and units propose a concept of Dormant BWP, where Dormant BWP can be understood that the UE does not need to blindly detect an uplink grant (UL grant) and a downlink grant (DL grant) on the BWP, and the base station can only allow the UE to perform CSI measurement and measurement report by cross-carrier scheduling of a Primary Cell (Pcell), and at this time, the base station is not turned off relative to the RF on the Scell, which is equivalent to reducing the aforementioned activation processing delay part. In addition, the DCI-based BWP can be used for switching the fast switching dormant BWP to an active BWP, which is equivalent to greatly reducing the activation starting time delay part, so that the aim of fast activating Scell can be achieved in conclusion, and standardization work is carried out in the R16 standard protocol.

However, the TRS method is also proposed at present, the activation of Scell is still activated through MAC-CE signaling, and T is optimized by introducing TRS_{activation_time}The AGC adjusting part in the time delay can also effectively reduce the Scell activation time delay, thereby achieving the purpose of quickly activating the Scell, but deep discussion is not performed in the R16 standard protocol, and related standardization work is not performed, and the TRS scheme is further discussed under the Dynamic Spectrum Sharing (DSS) issue of the R17 standard. Wherein TRS may be non-weeklyReference signals such as periodic tracking reference signals (a-TRSs), semi-persistent channel state information reference signals (SP CSI-RS), Aperiodic channel state information reference signals (a-CSI-RS), and semi-persistent tracking reference signals (SPTRSs).

The following two methods of activating Scell occur simultaneously, but not much disclosure is made of the details of the scheme.

(1): an independent Scell activation command and an independent (re-use existing) Reference RS activation mechanism;

(2): the Reference RS and the scelactivity command are combined into one command.

The TRS is a special CSI-RS, and is intended for channel tracking, and the UE performs precise time-frequency synchronization. The NR system supports periodic and aperiodic TRSs, where a periodic TRS is a CSI-RS resource set including multiple periodic CSI-RS resources, and the resource set configuration includes a high layer signaling indicating that the resource set is used as a TRS, and an aperiodic TRS has the same structure as a periodic TRS, and has the same frequency domain position and time slot if the same bandwidth is used, but an a-TRS in an NR needs to be triggered by DCI, and can be triggered only by UL Grant in a standard protocol at present.

In addition, the MAC layer is responsible for multiplexing multiple logical channels (logical channels) onto the same transport Channel (transport Channel), the Scell activation/deactivation MAC-CE signaling format is shown in fig. 1b and 1c, where Ci is used to indicate the activation/deactivation state of the Scell corresponding to the Scell index i, the Ci domain is set to 1 to indicate the Scell activation, otherwise, the Scell deactivation is indicated, and R is a reserved bit. If the number of aggregated cells is less than 8 scells using the structure of fig. 1b, and if greater than 7 scells using the structure of fig. 1c, the corresponding Logical Channel Identifiers (LCIDs) are 57 and 58 in table 2, respectively. Table 2 records LCID values of the downlink shared data signal (DL-SCH).
