The network device 102 in the embodiment of the present application also includes equipment that provides base station functions in new future communication systems.

Network energy saving (network energy saving or network power saving) is an issue that operators and equipment manufacturers are more concerned about. Network energy saving is very beneficial to reducing operating costs (economical) and green and environmentally friendly (low carbon). In the 5G network, due to the large number of spectrum resources, such as 1GHz, 2GHz, 4GHz, 6GHz and 26GHz, when the network load is low, the carriers corresponding to some frequency bands (such as 4GHz, 6GHz or 26GHz, etc.) (carrier) or cell (cell) can be turned off as much as possible and turned on as needed to achieve the purpose of network energy saving. That is to say, when the network load is low, some carriers or cells do not need to carry data, nor do they need to send common signals and/or channels. Generally speaking, network energy saving can be achieved by switching certain carriers or cells, but this can only be achieved when the network load is low.

Among them, the carrier or cell that can be turned on/off on demand can be called a non-anchor carrier (non-anchor carrier) or a non-anchor cell (non-anchor cell), or it can be called a current carrier or current cell. In contrast, a carrier or cell that is not closed may be called an anchor carrier or an anchor cell, or a conversion target carrier or a conversion target cell.

In a CA or DC scenario, there are two ways to understand anchor cells and non-anchor cells:

Method 1: The anchor cell is the primary carrier (primary carrier) or primary carrier component (primary carrier component) or primary cell (Primary Cell, PCell) or primary secondary cell (Primary Secondary Cell, PSCell), that is, it mainly carries control signaling. carrier or cell. The non-anchor cell is usually a secondary carrier (secondary carrier) or secondary carrier component (secondary carrier component) or secondary cell (Secondary Cell, SCell), that is, a carrier or cell that mainly carries data. At this time, the switch of the non-anchor cell can be understood as the addition, deletion or modification of the secondary cell. In this way, the requirements for the backhaul network (backhaul) between the anchor cell and the non-anchor cell are higher, but the switch of the non-anchor cell is easier to implement (through the addition, deletion or modification of the secondary cell).

Method 2: The anchor cell and the non-anchor cell are both primary carriers or primary carrier components or primary cells or primary and secondary cells, that is, carriers or cells that mainly carry control signaling. At this time, the opening of the non-anchor cell can be understood as a switch from the anchor cell to the non-anchor cell, and the closing of the non-anchor cell can be understood as a switch from the non-anchor cell to the anchor cell. In this way, the requirements for the backhaul network (backhaul) between the anchor cell and the non-anchor cell are low, but the switching implementation complexity of the non-anchor cell is high.

In the non-CA/DC scenario, similar to the second method in CA/DC, the opening of the non-anchor cell can be understood as the conversion from the anchor cell to the non-anchor cell, and the closing of the non-anchor cell can be understood as the conversion from the non-anchor cell to the non-anchor cell. Anchor cell conversion. At this time, the requirements for the backhaul network (backhaul) between the anchor cell and the non-anchor cell are low, but the switching implementation complexity of the non-anchor cell is high.

SSB can be used for UE to perform time-frequency synchronization and obtain Master Information Block (MIB) and System Information Block (SIB). For non-anchor carriers or non-anchor cells, they are only used for data load balancing and do not need to carry MIBs, so synchronization signal blocks (bursts) can be simplified. On the contrary, the anchor carrier or anchor cell needs to carry MIB and SIB to support cell search and system information transmission. Non-anchor carriers or non-anchor cells may still need to support paging, random access and Radio Resource Management (RRM) measurements, etc., so they still need to carry synchronization signal blocks to support time-frequency synchronization of user equipment ( time/frequency tracking) and RRM measurements.

Generally speaking, non-anchor cells are controlled by the network and are turned on or off on demand. When the non-anchor cell and the anchor cell belong to the same base station (such as CA scenario), the base station can turn on or off the non-anchor cell as needed; when the non-anchor cell and the anchor cell do not belong to the same base station, the anchor cell Point cell base stations can enable non-anchor cell base stations to turn on or off non-anchor cells on demand through inter-base station signaling. Alternatively, non-anchor cell base stations can turn on or off non-anchor cells on demand based on core network commands or signal/load requirements. community.

Generally speaking, the on-demand opening process of non-anchor cells is divided into the following two situations:

In case one, the timing of opening the non-anchor cell can be before the UE completes random access (Random Access, RA). This allows the UE to use the resources of the non-anchor cell as quickly as possible (making the non-anchor cell provide more load balancing), and reduces the signaling overhead when the connection state is switched (handover, HO). The random access process is generally divided into four steps, corresponding to the four channels or messages of the random access channel. The random access channel includes PRACH, also called Message 1 (Message 1 or Msg1), random access response (Random Access Response, RAR), also called Message 2 (Message 2 or Msg2), Message 3 (Message 3 or Msg3), Message 4 (Message 4 or Msg4) and so on. The timing for opening the non-anchor cell may be before the UE initiates random access, that is, before sending the PRACH. In this way, the UE can initiate random access or initiate a random access channel (Random Access Channel, RACH) process on the non-anchor cell, using the PRACH resources on the non-anchor cell. The timing for opening the non-anchor cell may also be after the UE initiates random access and before completing random access, such as before sending message 3. In this way, the UE can transfer to the non-anchor cell as quickly as possible after initiating random access on the anchor cell.

Scenario 2: The timing of opening the non-anchor cell can be after the UE completes random access, that is, after completing initial access or after entering the connected state. This allows the non-anchor cell to only serve connected UEs, increases the shutdown time of the non-anchor cell, and increases the energy-saving gain of the non-anchor cell.

As in case 2 above, when in the connected state, the UE can switch from the anchor cell to the non-anchor cell, that is, the primary cell switches from the anchor cell to the non-anchor cell. At this time, the following problems need to be solved:

Question 1: Regarding uplink synchronization.

When the anchor cell and the non-anchor cell are not synchronized, for example, the anchor cell and the non-anchor cell belong to different base stations (such as the aforementioned mode two in CA/DC or non-CA/DC), the anchor cell and the non-anchor cell The point cell belongs to the same base station but the antennas of the two are far apart (causing a large difference in propagation delay). Before switching to the non-anchor cell to send and receive data, the UE needs to establish uplink synchronization with the non-anchor cell through RA resources. There is a time offset between the signals from (downlink) and/or sent to (uplink) the anchor cell base station and the base station of the non-anchor cell. This time offset mainly includes the time offset between the two base stations (for example, different base stations) , the different propagation times caused by the different center frequencies of the anchor cell and the non-anchor cell and/or the different propagation times caused by the different distances between the UE and the two base stations. Therefore, it is necessary for the UE to establish uplink synchronization with the non-anchor cell.

For uplink synchronization, in the connected state, the UE is best to use Contention Free Random Access (CFRA) resources to improve the efficiency of establishing uplink synchronization in non-anchor cells. For uplink synchronization within the anchor cell, since the base station of the anchor cell knows which SSB of the anchor cell is suitable for the UE to use, the traditional method is for the base station to indicate an SSB (or beam) and its associated CFRA resources to the UE. information. However, for the uplink synchronization when switching from the anchor cell to the non-anchor cell, the base station of the anchor cell does not know which SSB of the non-anchor cell the UE is suitable to use. At this time, the base station should indicate to the UE multiple SSBs and their Associated CFRA resource information. At this time, the base station of the non-anchor cell actually uses beam sweeping to transmit SSB and configure its associated CFRA resources. Therefore, how the UE obtains one or more SSBs and their associated CFRA resource information is an issue that needs to be solved urgently.

Question 2: It’s also about uplink synchronization.

For uplink synchronization, when the base station of the anchor cell does not know the random access resource configuration of the non-anchor cell, the base station of the anchor cell cannot indicate CFRA resources to the UE. Correspondingly, the UE can only use contention-based random access ( Contention Based Random Access, CBRA) resources. Therefore, how the UE obtains the information whether to use CFRA resources or CBRA resources is also an issue that needs to be solved urgently.

Question 3: Regarding the bandwidth part.

When the UE switches to a non-anchor cell, it needs to determine which BWP to use. How the UE obtains the information of which BWP to use on the non-anchor cell is also an issue that needs to be solved urgently.

Question 4: Regarding the conversion of target communities.

The UE needs to determine which switching target cell to switch to. How the UE obtains which switching target cell it switches to is also an issue that needs to be solved urgently.

Faced with the above technical problems, embodiments of the present application provide a method for processing indication information, including:

For question 1, the base station can use the first indication information (for example, 1 bit) to indicate to the UE (even if there are multiple SSBs available to the UE, it may only indicate one SSB to the UE) the SSB of the non-anchor cell and its association. The CFRA resource is one or multiple. When the SSB indicating a non-anchor cell and its associated CFRA resource are one, fall back to the traditional usage of PDCCH order.

For question two, the base station can use second indication information (for example, another 1 bit) to indicate to the UE whether to use CFRA resources or CBRA resources.

For questions one and two, there is a correlation. When the first indication information indicates that the SSB of the non-anchor cell and its associated CFRA resource are one, the second indication information does not need to be used because in the traditional usage of PDCCH order, the "Random Access Preamble Index" is all 0 (meaningless). , the UE is instructed to use CBRA resources. That is to say, when the first indication information indicates that the SSB of the non-anchor cell and its associated CFRA resources are one , the second indication information does not need to be used. Combining questions one and two, the first indication information and the second indication information are jointly encoded into the third indication information (for example, 2 bits), and three states or code points (codepoints) are taken. For example, in state 1, there is one SSB for the non-anchor cell and its associated CFRA resources (falling back to the traditional usage of PDCCH order), and in state 2, there are multiple SSBs and their associated CFRA resources for the non-anchor cell, and use CFRA resources, state 3 means that the non-anchor cell has multiple SSBs and uses CBRA resources. This saves a state for later use.

For question three, the base station can use the fourth indication information to indicate to the UE the index (index), identification (ID), or number (number) of the BWP used on the non-anchor cell.

Regarding question 4, the base station may use the fifth indication information to indicate to the UE the frequency and/or identification (ID) of the target non-anchor cell for conversion.

It should be noted that in the embodiment of the present application, the current cell may also be used to represent the anchor cell, and the conversion target cell may be used to represent the non-anchor cell. In addition, except for the special description of "switching handover", handover is equivalent to conversion.

Detailed examples are used for detailed description below.

Referring to Figure 2, Figure 2 is a schematic flowchart of an instruction information processing method provided in an embodiment of the present application. In some embodiments, the indication information processing method can be applied to the UE.

Optionally, the above indication information processing method may be executed by the UE, or may be executed by a chip or a specific module in the UE.

The above instruction information processing methods include:

S201. Determine the status of the SSB according to the indication information, and/or determine the status of the random access resource for uplink synchronization.

For example, the status of SSB includes SSB status one and SSB status two.

Among them, one SSB status corresponds to one SSB. When the status of the SSB is SSB status one, the network device specifically indicates an SSB to the UE. SSB state two corresponds to one or more SSBs (not limited to one SSB). When the state of the SSB is SSB state 2, the network device may indicate multiple SSBs to the UE so that the UE selects an appropriate SSB and/or corresponding random access resource. It should be noted that there may be a corresponding relationship between SSB and random access resources (such as random access preamble, PRACH timing). The corresponding relationship may be preset or configured. Through the preset or configured corresponding relationship, random access resources can be indicated by only indicating the SSB, or SSB can be indicated by only indicating the random access resources, thereby reducing signaling overhead.

For example, the status of the random access resource includes random access resource status one and random access resource status two. Random access resource status one corresponds to CFRA resources. When the status of the random access resource is random access resource status 1, the network device specifically indicates the CFRA resource to the UE. Random access resource status 2 corresponds to CBRA resources. When the status of the random access resource is random access resource status 2, the network device can indicate the CBRA resource to the UE so that the UE can select an appropriate random access preamble and PRACH opportunity.

Specifically, a CFRA resource includes a group of PRACH opportunities and a group of random access preambles, and the group of PRACH opportunities and a group of random access preambles correspond to a group of SSBs. Alternatively, a CFRA resource includes a set of SSBs, a set of PRACH opportunities and a set of random access preambles. The PRACH opportunity is the time-frequency resource of PRACH. When one SSB corresponds to multiple PRACH opportunities, the PRACH mask can indicate one of the PRACH opportunities. PRACH timing may also be called PRACH mask. Generally speaking, the PRACH opportunity can be represented by the PRACH Mask Index, and the random access preamble can be represented by the Random Access Preamble Index. Access Preamble Index), SSB can be represented by SSB index. It should be understood that “a group” here includes both “one” and “multiple”. Unless otherwise specified, a CFRA resource can represent one CFRA resource or multiple CFRA resources. Generally speaking, one random access preamble within a CFRA resource corresponds to one SSB. One PRACH opportunity in one CFRA resource corresponds to a group of SSBs.

Specifically, a CBRA resource includes a set of PRACH opportunities and a set of random access preambles, and the set of PRACH opportunities and a set of random access preambles have a preset or configured corresponding relationship with the SSB. It should be understood that the SSB here may be the SSB actually sent. Due to preset or configured correspondence, CBRA resource configuration does not include SSB configuration. It should be understood that “a group” here includes both “one” and “multiple”. Unless otherwise specified, a CBRA resource can represent one CBRA resource or multiple CBRA resources.

In a feasible implementation, the above indication information can be carried by any one of PDCCH order, GC-PDCCH or MAC-CE.

For example, in some implementations, the above indication information can be carried by PDCCH order, so that PDCCH order signaling can be reused, saving signaling overhead and complexity.

In some implementations, the above indication information may be carried by GC-PDCCH. Among them, the above-mentioned first indication information can be sent to a group of UEs at the same time using GC-PDCCH, thereby saving signaling overhead.

In some implementations, the above indication information may be carried by MAC-CE. Among them, using MAC-CE to carry, the UE can feedback whether the PDSCH is successfully decoded (through HARQ-ACK signaling), thereby avoiding misunderstandings between the base station and the UE and reducing delay.

Based on the above indication information, the UE can determine the status of the SSB and/or determine the random access resource status for uplink synchronization.

For example, based on the above indication information, the UE can obtain different information to cope with the following different scenarios:

An SSB and its corresponding CFRA resources (traditional method);

Multiple SSBs and their corresponding CFRA resources;

An SSB and uses CBRA resources (when CBRA resources have been configured, there is no need to indicate random access resources);

Multiple SSBs and use CBRA resources (when CBRA resources have been configured, there is no need to indicate random access resources).

With the indication information processing method provided in this application, the UE can determine the status of the SSB and/or determine the random access resource status based on the indication information, thereby helping the UE cope with various uplink synchronization scenarios.

Based on the descriptions in the above embodiments, in some embodiments of the present application, the above indication information is first indication information; based on the first indication information, the UE can determine that the state of SSB is SSB state one or SSB state two.

Among them, SSB state one corresponds to one SSB, and SSB state two corresponds to one or more SSBs (not limited to one SSB).

For example, the base station can use the above first indication information to indicate to the UE that there are one or more SSBs of the non-anchor cell and its associated CFRA resources, thereby solving the above "problem one".

Optionally, the above-mentioned first indication information may be 1 bit, which can save bit overhead.

In some implementations, the above first indication information can be carried by PDCCH order, so that it can be reused PDCCH order signaling saves signaling overhead and complexity.

In some implementations, the above-mentioned first indication information may be carried by GC-PDCCH. Among them, the above-mentioned first indication information can be sent to a group of UEs at the same time using GC-PDCCH, thereby saving signaling overhead.

In some implementations, the above-mentioned first indication information may be carried by MAC-CE. Among them, using MAC-CE to carry, the UE can feedback whether the PDSCH is successfully decoded (through HARQ-ACK signaling), thereby avoiding misunderstandings between the base station and the UE and reducing delay.

In some embodiments, when the above-mentioned first indication information indicates that the state of the SSB is SSB state one, the PDCCH order field is not escaped (that is, the traditional meaning).

When the above-mentioned first indication information indicates that the state of the SSB is SSB state two, the PDCCH order field is escaped (ie, non-traditional meaning).

Among them, when the above-mentioned first indication information indicates that the state of SSB is SSB state two, the "SSB index (SSB index)", "random access preamble index" and "PRACH mask index" in the PDCCH order are no longer valid (or be retained). In this way, when the above-mentioned first indication information indicates that the state of the SSB is SSB state two, the fields that are no longer needed can be escaped into new fields.

Based on the descriptions in the above embodiments, in some embodiments of the present application, the above indication information is second indication information; based on the second indication information, the UE can determine that the random access resource status is random access resource status one or random access. Enter resource state two.

Random access resource status one corresponds to CFRA, and random access resource status two corresponds to CBRA resources.

For example, the base station can use the above-mentioned second indication information to indicate to the UE whether to use CFRA resources or CBRA resources, which can solve the above-mentioned "problem 2".

It can be understood that when the above-mentioned first indication information indicates that the state of SSB is SSB state one, the UE may not parse the second indication information, because at this time, the PDCCH order field is not escaped (that is, the traditional meaning), and has the traditional meaning. The method indicates whether to use CFRA resources or CBRA resources (the "Random Access Preamble Index" field is all 0).

Optionally, the above-mentioned second indication information may be 1 bit, which can save bit overhead.

In some implementations, the above-mentioned second indication information can be carried by PDCCH order, so that PDCCH order signaling can be reused, saving signaling overhead and complexity.

In some implementations, the above-mentioned second indication information may be carried by GC-PDCCH. Among them, the above-mentioned first indication information can be sent to a group of UEs at the same time using GC-PDCCH, thereby saving signaling overhead.

In some implementations, the above-mentioned second indication information may be carried by MAC-CE. Among them, using MAC-CE to carry, the UE can feedback whether the PDSCH is successfully decoded (through HARQ-ACK signaling), thereby avoiding misunderstandings between the base station and the UE and reducing delay.

In some embodiments, it can be understood that when the base station instructs the UE to use CBRA resources, the UE does not use the indicated CFRA resources associated with the SSB of the non-anchor cell, but only uses the indicated SSB associated with the non-anchor cell. CBRA resources.

Based on the description in the above embodiments, in some embodiments of the present application, the above indication information is the third indication information; according to the third indication information, the UE can determine that the state of the SSB is SSB state one or SSB state two, and determine the random The access resource status is random access resource status one or random access resource status two.

Among them, SSB state one corresponds to one SSB, and SSB state two corresponds to one or more SSBs (not limited to one SSB). Random access resource status one corresponds to CFRA, and random access resource status two corresponds to CBRA resources.

Among them, when the above-mentioned first indication information indicates that the SSB of the non-anchor cell is one, the second indication information does not need to be used, because in the traditional usage of PDCCH order, when the "Random Access Preamble Index" is all 0 (meaningless), give The UE indicates the use of CBRA resources. That is to say, when the above-mentioned first indication information indicates that the SSB of the non-anchor cell is one, the second indication information may not be used. This shows that the above-mentioned first indication information and the second indication information can be jointly encoded into the above-mentioned third indication information, so as to simultaneously solve the above-mentioned "problem one" and "problem two".

Optionally, the above third indication information may be 2 bits, which can save bit overhead.

Optionally, the above third indication information may include three states or code points. In this way, a state can be saved for later use, thus improving the forward compatibility and flexibility of the system.

Among them, the above third indication information can indicate the following states:

Status 1: Indicates SSB status one;

State 2: Indicates SSB state two and random access resource state one;

State 3: Indicates SSB state two and random access resource state two.

In some embodiments, the above-mentioned state 1 is the SSB of the non-anchor cell and its associated CFRA resources (falling back to the traditional usage of PDCCH order); the above-mentioned state 2 is the SSB of the non-anchor cell and its associated CFRA. There are multiple resources, and CFRA resources are used; the above state 3 is that the SSB of the non-anchor cell is one or more, and CBRA resources are used.

Optionally, the above third indication information can be carried by PDCCH order, so that PDCCH order signaling can be reused and signaling overhead and complexity can be saved.

In some implementations, the above third indication information may be carried by GC-PDCCH. Among them, the above-mentioned first indication information can be sent to a group of UEs at the same time using GC-PDCCH, thereby saving signaling overhead.

In some implementations, the above third indication information may be carried by MAC-CE. Among them, using MAC-CE to carry, the UE can feedback whether the PDSCH is successfully decoded (through HARQ-ACK signaling), thereby avoiding misunderstandings between the base station and the UE and reducing delay.

The instruction information processing method provided by the embodiment of the present application can include most scenarios, that is, one SSB and its corresponding CFRA resources (traditional method), multiple SSBs and their corresponding CFRA resources, one or more SSBs and using CBRA resources (there is no need to indicate random access resources at this time).
