In order to facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific examples. The following related technologies can be combined arbitrarily with the technical solutions of the embodiments of the present application as optional solutions, and all of them belong to the protection scope of the embodiments of the present application. The embodiment of the present application includes at least part of the following contents.

The main application scenarios of 5G are: Enhanced Mobile Broadband (Enhance Mobile Broadband, eMBB), Ultra-Reliable and Low Latency Communication (URLLC), Massive machine type of communication (mMTC) ).

eMBB still aims at users' access to multimedia content, services and data, and its demand is growing rapidly. On the other hand, since eMBB may be deployed in different scenarios, such as indoors, urban areas, and rural areas, the capabilities and requirements vary greatly, so it cannot be generalized and must be analyzed in detail in combination with specific deployment scenarios. Typical applications of URLLC include: industrial automation, electric power automation, telemedicine operations (surgery), traffic safety guarantee, etc. The typical characteristics of mMTC include: high connection density, small data volume, delay-insensitive services, low cost and long service life of modules, etc.

NR is deployed on high frequencies. In order to improve coverage, in 5G, the mechanism of beam sweeping is introduced to meet the coverage requirements (use space for coverage and time for space), as shown in Figure 2.

After the introduction of beam sweeping, synchronization signals need to be sent in each beam direction. 5G synchronization signals are given in the form of synchronization signal blocks (SS/PBCH block, SSB), including primary synchronization signals (Primary Synchronization Signal, PSS)/ Secondary Synchronization Signal (SSS)/Physical Broadcast Channel (PBCH).

The 5G synchronization signal appears periodically in the time domain in the form of a Synchronization Signal burst set.

The number of beams (beams) actually transmitted by each cell is determined by configuration on the network side, but the frequency point where the cell is located determines the maximum number of beams (beams) that can be configured.

In 5G, the maximum channel bandwidth can be 400MHz (such as wideband carrier), which is very large compared to the maximum 20M bandwidth of LTE. If a terminal device remains operating on a broadband carrier, the power consumption of the terminal device is significant. Therefore, the radio frequency (RF) bandwidth of the terminal device can be adjusted according to the actual throughput of the terminal device. And introduce the Band Width Part (BWP) to optimize the power consumption of the terminal equipment. For example, if the rate of the terminal device is very low, a smaller bandwidth can be configured for the terminal device (as shown in (a) in Figure 3). If the rate requirement of the terminal device is very high, a larger bandwidth can be configured for the terminal device ( As shown in (b) in Figure 3). If the terminal device supports a high rate, or operates in carrier aggregation (Carrier Aggregation, CA) mode, multiple BWPs can be configured for the terminal device (as shown in (c) in Figure 3). Another purpose of the BWP is to trigger the coexistence of multiple numerologies in a cell.

In some embodiments, a terminal device can be configured with up to 4 uplink (uplink, UL) BWPs and up to 4 downlink (downlink, DL) BWPs through radio resource control (Radio Resource Control, RRC) dedicated signaling, but Only one DL BWP and UL BWP can be activated at the same time. In the RRC dedicated signaling, the first activated BWP among the configured BWPs may be indicated. At the same time, when the terminal device is in the connected state, it can also switch between different BWPs through downlink control information (Downlink Control Information, DCI). When the carrier in the inactive state enters the active state, the first activated BWP is the first activated BWP configured in the RRC.

In some embodiments, configuration parameters for each BWP include:

subcarrier spacing (subcarrierSpacing);

cyclic prefix (cyclicPrefix);

The first physical resource block (physical resource block, PRB) of the BWP and the number of consecutive PRBs;

location and bandwidth (locationAndBandwidth);

BWP identification (bwp-Id);

BWP common configuration parameters (bwp-Common) and dedicated configuration parameters (bwp-Dedicated).

In some embodiments, the UE monitors the radio link monitoring (radio link monitoring, RLM) process, only on the active BWP, the inactive BWP does not need to be operated, and when switching between different BWPs, There is also no need to reset RLM related timers and counters. For radio resource management (Radio Resource Management, RRM) measurement, no matter which activated BWP the UE sends and receives data on, it will not affect the RRM measurement. For the channel quality indicator (Channel Quantity Indicator, CQI) measurement, the UE only needs to perform it on the activated BWP.

When a carrier is deactivated and then activated through the Media Access Control Element (MAC CE), the initial first activated BWP is the first activated one in the RRC signaling The BWP corresponding to the BWP identifier (BWP id).

BWP id ranges from 0 to 4 in RRC signaling, and 0 defaults to the initial BWP.

In the DCI, the BWP indicator (indicator) is 2 bits. If the number of configured BWPs is less than or equal to 3, then BWP indicator=1, 2, 3 correspond to BWP id=1, 2, 3 respectively. If the number of BWPs is 4, then BWP indicator=0, 1, 2, 3 correspond to the BWPs configured according to the sequence index respectively. Moreover, the network side uses continuous BWP ids when configuring BWP.

Carrier Aggregation (Carrier Aggregation, CA), that is, through joint scheduling and use of resources on multiple component carriers (Component Carrier, CC), the NR system can support a larger bandwidth, thereby enabling a higher system peak rate. According to the continuity of the aggregated carrier in the spectrum, it can be divided into continuous carrier aggregation and non-continuous carrier aggregation; according to whether the bands of the aggregated carriers are the same, it can be divided into Intra-band carrier aggregation and out-of-band (inter-band) carrier aggregation.

There is only one primary carrier (Primary Cell Component, PCC). PCC provides RRC signaling connection, Non-Access Stratum (Non-Access Stratum, NAS) function, security, etc. The Physical Uplink Control Channel (PUCCH) exists on the PCC and only on the PCC. The secondary carrier (Secondary Cell Component, SCC) only provides additional radio resources. The PCC and the SCC are both called serving cells. Aggregated carriers support a maximum of 5, that is, the maximum bandwidth after aggregation is 100MHz, and the aggregated carriers belong to the same base station. All aggregated carriers use the same Cell Radio Network Temporary Identity (C-RNTI), and the base station ensures that the C-RNTI does not collide in the cell where each carrier is located. Since asymmetric carrier aggregation and symmetric carrier aggregation are supported, it is required that the aggregated carrier must have downlink, but may not have uplink. Moreover, for the primary carrier cell, there must be a Physical Downlink Control Channel (PDCCH) and PUCCH of the cell, and only the primary carrier cell has the PUCCH, and other secondary carrier cells may have the PDCCH.

The SCell is configured through RRC dedicated signaling, and the initial configuration state is the deactivated state, and data cannot be sent and received in this state. Then the SCell is activated through the MAC CE to send and receive data. For example, as shown in FIG. 4 , the SCell is activated (Activation) or deactivated (Deactivation) through an octet (octet, Oct) of the MAC CE. For another example, as shown in FIG. 5, the SCell is activated (Activation) or deactivated (Deactivation) through 4 octets (octet, Oct) of the MAC CE. Specifically, for example, setting a bit to 0 indicates that the corresponding Scell is deactivated, and setting it to 1 indicates that the corresponding Scell is activated; or, setting a bit to 1 indicates that the corresponding Scell is deactivated, and setting it to 0 indicates that the corresponding Scell is activated.

In some embodiments, the state of the Scell may be in the RRC signaling. When the Scell is added and configured, the state of the Scell is configured as the active state through the RRC signaling, otherwise the default is the deactivated state.

In order to better understand the embodiments of the present application, the technical problems to be solved in the present application are described.

At this stage, the MAC CE method requires a delay from the activation of a Scell to the actual transmission of data. Considering that the length of the large SSB cycle will affect the actual activation time of the Scell, therefore, TRS is introduced to assist the terminal equipment to quickly activate the Scell. The transmission of TRS will occupy two consecutive time slots (slots), which may conflict with other transmissions. For example, the transmission of TRS and the transmission on the UL time slot conflict, resulting in unsuccessful TRS transmission. How to identify and deal with conflicts, is a problem that needs to be solved.

Based on the above problems, this application proposes a scheme for identifying and handling transmission conflicts, which can identify and deal with conflicts between the transmission of the first reference signal and the uplink transmission. When the first reference signal is a TRS, the terminal device can The SCell is quickly activated based on the first reference signal.
