During a process of activating a Serving Cell (SCell), an activation delay of the SCell is mainly affected by a Synchronization Signal Block (SSB) period. If a terminal device just misses an SSB period after receiving an SCell activation instruction, the activation delay of the SCell will be prolonged. In order to solve this problem, a TRS may be introduced to replace the SSB, thus realizing faster activation of the SCell. However, how to activate the TRS is an unsolved problem.

It should be noted that
In order to facilitate understanding of the technical schemes of the embodiments of the present disclosure, the technical technology related to the embodiments of the present disclosure are described below, and the following related technologies, as optional schemes, can be arbitrarily combined with the technical schemes of the embodiments of the present disclosure, all of which belong to the protection scope of the embodiments of the present disclosure.
With people's pursuit of speed, latency, high-speed mobility and energy efficiency, as well as the diversity and complexity of business in future life, the International Organization for Standardization (ISO) of the 3rd Generation Partnership Project (3GPP) began to develop the 5G mobile communication technology (hereinafter referred to as 5G for short). The main application scenarios of 5G are: enhanced Mobile Broadband (cMBB), Ultra-Reliable Low-Latency Communications (URLLC) and massive Machine-Type Communications (mMTC).
On one hand, eMBB still aims at users' access to multimedia content, services and data, the demand of eMBB is growing rapidly. On the other hand, cMBB may be deployed in different scenarios, such as indoor, urban and rural areas, and the capabilities and the demand of eMBB are quite different in different scenarios, so it cannot be generalized and must be analyzed in detail in combination with specific deployment scenarios. Typical applications of URLLC include industrial automation, power automation, telemedicine operation (surgery), traffic safety and so on. The typical characteristics of mMTC include high connection density, small data volume, delay-insensitive services, low cost and long service life of modules and so on.
In the early deployment of NR systems, it is difficult to obtain complete NR coverage, so the typical network coverage is in a mode of wide-area LTE coverage and NR island coverage. Moreover, a large number of LTE systems are deployed below 6 GHz, and there are few spectra below 6 GHz available for 5G. Therefore, NR must study the application of spectra above 6 GHZ, but the coverage of high frequency band is limited and the signal fades quickly. Furthermore, in order to protect the early investment of mobile operators in LTE, a working mode of tight interworking between LTE and NR is proposed.
In order to be able to implement the 5G network deployment and commercial applications as soon as possible, the 3GPP first completed the first 5G version, i.e., the EN-DC (LTE-NR Dual connectivity). In the EN-DC, an LTE base station (eNB) serves as a Master Node (MN), an NR base station (gNB or en-gNB) serves as a Secondary Node (SN), and the two base stations are connected to an EPC core network. In the later stage of R15, other Dual Connectivity (DC) modes will be supported, i.e., NE-DC (New radio E-UTRA DC), 5GC-EN-DC and NR DC (New Radio DC). In the NE-DC, an NR base station serves as the MN, an evolved LTE (eLTE) base station serves as the SN, and the two base stations are connected to the 5GC core network. In the 5GC-EN-DC, the eLTE base station serves as the MN, the NR base station serves as the SN, and the two base stations are connected to the 5GC core network. In the NR DC, the NR base station is used as the MN, the NR base station serves as the SN, and the two base stations are connected to the 5GC core network.
In 5G, the maximum channel bandwidth can be 400 MHZ (which is called wideband carrier), which is very large compared with the maximum bandwidth of 20 MHz in LTE. In order to meet the requirement of high rate, the CA technology is supported in 5G. The CA technology jointly schedules and uses resources on multiple Component Carriers (CCs), so that NR systems can support larger bandwidth, thus higher peak rate of the system can be achieved. According to the continuity of the aggregated carriers in spectrum, the CA can be divided into continuous carrier aggregation and discontinuous carrier aggregation; according to whether the aggregated carriers are located in a same band, the CA can be divided into Intra-band carrier aggregation and inter-band carrier aggregation.
In the CA, there is one and only one Primary Component Carrier (PCC, also referred to as primary cell component), and the PCC provides an RRC signaling connection, a Non-Access Stratrum (NAS) function, security and so on. The Physical Uplink Control Channel (PUCCH) exists on and only on the PCC. In the CA, there can be one or more Secondary Component Carriers (SCCs, also referred to as secondary cell components), and the SCC only provides additional radio resources. The PCC and SCC are both called serving cells, the cell on the PCC is the primary cell (Pcell) and the cell on the SCC is the secondary cell (Scell).
The network device may instruct the terminal device to activate one or more SCells and/or deactivate one or more SCells through an MAC CE, and the MAC CE may be referred to as an SCell activation/deactivation MAC CE. The SCell activation/deactivation MAC CE has a fixed length. As an implementation, the length of the SCell activation/deactivation MAC CE is 1 byte, which is adaptable to a scenario where the network device configures the terminal device with less than or equal to 7 SCells. As another implementation, the length of the SCell activation/deactivation MAC CE is fixed to 4 bytes, which is adaptable to a scenario where the network device configures the terminal device with more than 7 and less than or equal to 31 SCells. The two lengths of MAC CE are respectively associated with different Logical Channel Identifies (LCIDs), and the terminal device may distinguish the MAC CEs having two lengths according to the LCIDs. As shown in
In the process of activating the SCell, it is assumed that the terminal device receives the MAC CE for indicating the activation of the SCell on the time slot n, then the terminal device sends a Channel State Information (CSI) report and performs the activation of the SCell at a time not later than:
In view of this, the following technical schemes in the embodiments of the present disclosure are proposed.

The TRS offset information is used for determining a starting time-domain position of the first TRS in the TRS burst.
In the above scheme, the fourth information is optionally located after the second information and the length of the fourth information is variable. The length of the fourth information is associated with the number of target SCells, and the target SCell is a to-be-activated SCell of which the TRS is to be activated. The target SCell is determined based on the first information and the second information. For example, if the number of target SCells indicated by the first information and the second information is P, the fourth information includes TRS information corresponding to the P SCells.

In an embodiment of the present disclosure, the first MAC CE carries third information for indicating at least one of: whether each of the multiple SCells is to be activated or deactivated, or whether a TRS of the SCell is to be activated.
In some alternative implementations, the third information includes N bits, each M bits among the N bits corresponds to one SCell, a value of the M bits is used for indicating whether the SCell corresponding to the M bits is to be activated or deactivated, or whether a TRS of the SCell is to be activated, where N and M are positive integers.
In some alternative implementations, when a value of the M bits is a first value, the M bits are used for indicating that the SCell corresponding to the M bits is to be deactivated; when a value of the M bits is a second value, the M bits are used for indicating that the SCell corresponding to the M bits is to be activated and the TRS of the SCell is not to be activated; and when a value of the M bits is a third value, the M bits are used for indicating that the SCell corresponding to the M bits is to be activated and the TRS of the SCell is to be activated.
In the above scheme, taking M=2 as an example, any three of the four values of the two bits may be used as the first value, the second value and the third value, respectively. For example, a value of the 2 bits being 00 represents the first value, a value of the 2 bits being 01 represents the second value, and a value of the 2 bits being 10 represents the third value.
Furthermore, in some alternative implementations, the first MAC CE further carries fourth information including TRS information corresponding to each of at least one target SCell, where the target SCell is a to-be-activated SCell of which the TRS is to be activated.
In some alternative implementations, the TRS information includes at least one of: a TRS index, TRS burst information, or TRS offset information.
As an implementation, the TRS information includes a TRS index, TRS burst information, and TRS offset information. Herein, the TRS index is used for indicating the TRS configuration, and the TRS configuration includes information such as time-frequency resources of the TRS. The TRS burst information is used for determining a number of successive TRS contained in the TRS burst. The TRS offset information is used for determining a starting time-domain position of the first TRS in the TRS burst.
As an implementation, the TRS information further includes a TRS index. [00126] Herein, the TRS index is used for indicating the TRS configuration and the TRS configuration includes time-frequency resource information of the TRS, TRS burst information, and TRS offset information. The TRS burst information is used for determining a number of successive TRS contained in the TRS burst. The TRS offset information is used for determining a starting time-domain position of the first TRS in the TRS burst.
In the above scheme, the fourth information is optionally located after the second information and the length of the fourth information is variable. The length of the fourth information is associated with the number of target SCells, and the target SCell is a to-be-activated SCell of which the TRS is to be activated. The target SCell is determined based on the third information. For example, if the number of the target SCells indicated by the third information is P, the fourth information includes TRS information corresponding to the P SCells. For the content of each TRS information, reference may be made to the aforementioned scheme.
In the above scheme, each piece of the TRS information in the fourth information has a one-to-one correspondence with the target SCell (i.e., the to-be-activated SCell of which the TRS is to be activated) among the multiple SCells. Optionally, the TRS information in the fourth information in an order from front to back corresponds to the at least one target SCell in an ascending order of SCell indexes; or the TRS information in the fourth information in the order from front to back corresponds to the at least one target SCell in a descending order of SCell indexes.
In an embodiment of the present disclosure, the first MAC CE carries first information and second information. The first information is used for indicating whether each of the multiple SCells is to be activated or deactivated, and the second information is used for indicating whether the TRSs of the at least part of the multiple SCells are to be activated.
In some alternative implementations, the second information is used for indicating whether the TRSs of part of the multiple SCells are to be activated. The part of the SCells includes to-be-activated SCells among the multiple SCells.
Specifically, at least one first SCell of the multiple SCells is to be activated through indication of the first information. The second information includes indication information of a first trigger state, the indication information of the first trigger state being used for indicating that TRSs of one or more first SCells associated with the first trigger state are to be activated.
Furthermore, in some alternative implementations, the indication information of the first trigger state is further used for indicating at least one of the following of the one or more first SCells associated with the first trigger state: TRS configurations, TRS burst information, or TRS offset information.

Optionally, the association relationship may be configured by RRC signaling. The network device indicates that the TRSs of one or more SCells associated with the first trigger state are to be activated by carrying the indication information of the first trigger state in the first MAC CE.
In the above scheme, the length of the first information is fixed. As an implementation, the first information occupies 1 byte and is used for indicating whether each of 7 SCells is to be activated or deactivated, which is adaptable to the scenario where the network device configures the terminal device with less than or equal to 7 SCells. As another implementation, the first information occupies 4 bytes and is used for indicating whether each of 31 SCells is to be activated or deactivated, which is adaptable to the scenario where the network device configures the terminal device with more than 7 and less than or equal to 31 SCells.
In the above scheme, the length of the second information is fixed or variable. As an implementation, the second information includes only indication information of one trigger state. As another implementation, the second information includes indication information of multiple trigger states. In this case, indication of activation of the TRS of the SCell associated with each of the multiple trigger states can be implemented.

If Ci=01, it represents that the SCell with the SCell index of i is to be activated but the TRS of the SCell is not to be activated.

A terminal device receives a first MAC CE sent by a network device, and the first MAC CE includes first information and second information. The first information is used for indicating whether each of the multiple SCells is to be activated or deactivated, and description is made by taking the multiple SCells including 7 SCells as an example. The second information is used for indicating one or more trigger states, and one trigger state is described as an example. Each trigger state is associated with the TRSs of one or more SCells, and the activation of the TRSs of the one or more SCells associated with the trigger state is indirectly indicated by indicating the trigger state through the second information. The format of the first MAC CE is shown in
1) The terminal device determines to-be-activated SCells and/or to-be-deactivated SCells according to the Ci field of the first information. For example, C7=1, C5=1, C3=1, C1=1, it respectively represents that SCells with SCell indexes of 7, 5, 3, 1 are to be activated. 2) According to the trigger state indicated by the second information, the terminal device determines that the TRSs of the SCells with SCell indexes of 7, 5 associated with the trigger state are to be activated. 2) The terminal device may also determine, according to the second information, the TRS configurations of the SCells with SCell indexes of 7, 5 associated with the trigger state.
The length of each field (such as a TRS index field, a TRS burst field, and a TRS offset field) of the TRS information may be determined by the terminal device in the following manners. Hereinafter, the field may be called as the target field for ease of description.
The length of the target field is fixed.
Taking the TRS index field as an example, for 7 SCells, the number of supported TRS configurations is 6, 8, 1, 4, 6, 10 and 14 respectively. In order to ensure that the first MAC CE can be used for indicating the number of TRS configurations supported by all SCells, the number of bits occupied by the TRS index field is 4, i.e., supporting up to 15 TRS indexes The number of bits occupied by the TRS burst field and the TRS offset field are determined in the same manner.
The length of the target field is variable. For different SCells and/or different terminal devices, the network device may pre-configure the length of the target field through the RRC message.
As an implementation, different SCells correspond to different lengths of the target fields. For example, the lengths of the three fields of an SCell with the SCell index of 1 are configured to be 4 bits, 2 bits, and 2 bits, respectively. The lengths of the three fields of an SCell with the SCell index of 2 are configured to be 2 bits, 1 bit, and 1 bit, respectively. Once the length of the target field corresponding to each SCell is determined, the lengths of the target fields of all terminal devices corresponding to a same SCell are the same.
As another implementation, different terminal devices correspond to different lengths of the target fields. For example, for a terminal device #1 and the SCell with the SCell index of 1, the lengths of the three fields are 4 bits, 2 bits and 2 bits, respectively. For a terminal device #2 and the SCell with the SCell index of 1, the lengths of the three fields are 2 bits, 1 bit, and 1 bit, respectively. The configuration information for configuring the lengths of the target fields may be explicitly configured through the RRC message, or implicitly determined according to the number of TRS candidate configurations. For example, if the network device configures 12 TRS configurations, 4 TRS bursts and 3 TRS offsets for the terminal device, respectively, accordingly, the lengths of the three fields are 4 bits, 2 bits and 2 bits, respectively.
It should be noted that in the technical schemes of the embodiments of the present disclosure, the lengths of the TRS index, the TRS burst and the TRS offset are all greater than or equal to 1 bit, and the present disclosure does not limit the specific number of the bits.
It should be noted that in the technical schemes of the embodiments of the present disclosure, although the three fields of TRS index, TRS burst and TRS offset are arranged in the order from higher bit to lower bit, the present disclosure does not limit the arrangement order of the three fields and the positions of the three fields.

It should be noted that in the technical schemes of the embodiments of the present disclosure, the TRS burst information and the TRS offset information may be contained or may not be contained in the TRS configuration. If the TRS burst information and the TRS offset information are contained in the TRS configuration, the first MAC CE may not contain the TRS burst field and the TRS offset field.
