Description

Indication information processing method and device

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to an indication information processing method and apparatus.

Background

As the size of communication networks continues to expand, the power consumption of communication networks also continues to increase. In order to reduce the operating costs, various energy saving measures have been adopted in the prior art to reduce the power consumption of the communication network.

For example, in the fifth generation mobile communication technology (5th Generation Mobile Communication Technology,5G) network, because of more spectrum resources, when the network load is low, cells corresponding to some frequency bands can be selectively turned off and turned on as required, so as to achieve the purpose of network energy saving. Among them, a cell that can be turned on/off as needed may be referred to as a handover target cell; in contrast, a cell that is not turned off may be referred to as a current cell.

The network device 102 in the embodiment of the present application also includes a device that provides a base station function in a new communication system in the future, and the like.

Network power saving (network energy savings or network power saving) is a concern for operators and equipment vendors. Network energy conservation is beneficial to reducing operating cost (economy) and environmental protection (low carbon). In a 5G network, since there are many frequency spectrum resources, such as bands (bands) of 1GHz, 2GHz, 4GHz, 6GHz, and 26GHz, when the network load is low, carriers (carriers) or cells (cells) corresponding to some frequency bands (e.g. 4GHz, 6GHz, or 26 GHz) can be turned off as much as possible and turned on as required, so as to achieve the purpose of network energy saving. That is, some carriers or cells need not carry data and need not transmit common signals and/or channels when the network load is low. Generally, the purpose of network energy saving can be achieved through the switching of certain carriers or cells, but this is generally achieved when the network load is low.

Among them, a carrier or a cell that can be turned on/off as needed may be called a non-anchor carrier (non-anchor carrier) or a non-anchor cell (non-anchor cell), or a current carrier or a current cell. In contrast, a carrier or cell that is not turned off may be referred to as an anchor carrier (anchor carrier) or an anchor cell (anchor cell), or as a handover target carrier or a handover target cell.

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

mode one: the anchor Cell is a Primary carrier (Primary carrier) or Primary carrier component (Primary carrier component) or Primary Cell (PCell) or Primary secondary Cell (Primary Secondary Cell, PSCell), i.e. a carrier or Cell that mainly carries control signaling. The non-anchor cells are typically Secondary carriers (Secondary carrier) or Secondary carrier components (Secondary carrier component) or Secondary cells (scells), i.e. carriers or cells that mainly carry data. At this time, the switching of the non-anchor cell may be understood as the addition, deletion or modification of the secondary cell. In this way, the requirement for backhaul network (backhaul) between the anchor cell and the non-anchor cell is higher, but switching of the non-anchor cell is easier to implement (by addition, deletion or modification of the secondary cell).

Mode two: both the anchor cell and the non-anchor cell are primary carriers or primary carrier components or primary cells or primary and secondary cells, i.e. carriers or cells that mainly carry control signaling. At this time, the opening of the non-anchor cell may be a switch from the anchor cell to the non-anchor cell, and the closing of the non-anchor cell may be understood as a switch from the non-anchor cell to the anchor cell. In this way, the requirement of the backhaul network (backhaul) between the anchor cell and the non-anchor cell is lower, but the switching implementation complexity of the non-anchor cell is higher.

In the non-CA/DC scenario, like in the second mode of CA/DC, the opening of the non-anchor cell may be understood as the switching of the anchor cell to the non-anchor cell, and the closing of the non-anchor cell may be the switching of the non-anchor cell to the anchor cell. At this time, the requirement of a backhaul network (backhaul) between the anchor cell and the non-anchor cell is low, but the switching implementation complexity of the non-anchor cell is high.

SSBs may be used for time-frequency synchronization by UEs, acquisition of master information blocks (Master Information Block, MIB) and system information blocks (System Information Block, SIBs). For non-anchor carriers or non-anchor cells, they serve only as data load balancing purposes, without carrying MIB, so that synchronization signal blocks (bursts) can be simplified. Conversely, anchor carriers or anchor cells need to carry MIB and SIBs to support cell search and system information transmission. The non-anchor carrier or non-anchor cell may still need to support paging, random access, and radio resource management (Radio Resource Management, RRM) measurements, etc., and thus still need to carry synchronization signal blocks to support time-frequency synchronization (time/frequency tracking) and RRM measurements by the user equipment.

Generally, non-anchor cells are network controlled and turned on or off as needed. When the non-anchor cell and the anchor cell belong to the same base station (such as CA scene), the base station can open or close the non-anchor cell according to the requirement; when the non-anchor cell and the anchor cell do not belong to the same base station, the anchor cell base station can enable the non-anchor cell base station to open or close the non-anchor cell according to the needs through signaling between base stations, or the non-anchor cell base station opens or closes the non-anchor cell according to the needs of a core network command or a signal/load.

In general, the on-demand open flow of non-anchor cells is divided into the following two cases:

in case one, the non-anchor cell may be turned on before the UE completes Random Access (RA). This allows the UE to use the resources of the non-anchor cell as soon as possible (more load balancing is provided by the non-anchor cell) and reduces the signalling overhead when the Handover (HO) is done in the connected state. The random access procedure is generally divided into four steps, corresponding to four channels or messages of the random access channel, respectively. The random access channel includes PRACH, also called Message 1 (Message 1 or Msg 1), random access response (Random Access Response, RAR), also called Message 2 (Message 2 or Msg 2), message 3 (Message 3 or Msg 3), message 4 (Message 4 or Msg 4), and so on. The non-anchor cell may be turned on before the UE initiates random access, i.e., before the PRACH is transmitted. In this way, the UE may initiate random access or initiate a random access channel (Random Access Channel, RACH) procedure on the non-anchor cell, using PRACH resources on the non-anchor cell. The non-anchor cell may be turned on before the UE completes the random access after initiating the random access, for example, before sending the message 3. In this way, the UE may transfer to the non-anchor cell as soon as possible after initiating random access on the anchor cell.

In case two, the non-anchor cell may be turned on after the UE completes random access, i.e. after completing initial access or entering a connected state. Therefore, the non-anchor point cell can only serve the connected UE, the closing time of the non-anchor point cell is increased, and the energy-saving gain of the non-anchor point cell is increased.

As in case two above, in the connected state, the UE may switch from the anchor cell to the non-anchor cell, i.e. the primary cell switches from the anchor cell to the non-anchor cell. At this time, the following problems need to be solved:

problem one: problems with 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 (for example, the second mode in the aforementioned CA/DC or the non-CA/DC), the anchor cell and the non-anchor cell belong to the same base station but are far apart from each other (causing a large difference in propagation delay), and before switching to the non-anchor cell to transmit 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 (downstream) and/or to (upstream) the base stations of the anchor cell and the non-anchor cell, which mainly comprises a time offset between the two base stations itself (e.g. different base stations), a difference in propagation time due to a difference in frequency point between the anchor cell and the non-anchor cell, and/or a difference in propagation time due to a difference in distance between the UE and the two base stations, so that it is necessary for the UE to establish upstream synchronization with the non-anchor cell.

For uplink synchronization, in the connected state, the UE preferably uses contention-free random access (Contention Free Random Access, CFRA) resources to improve the efficiency of establishing uplink synchronization in the non-anchor cell. For uplink synchronization within an anchor cell, the conventional approach is for the base station to indicate to the UE one SSB (or called beam) and its associated CFRA resource information, since the base station of the anchor cell knows which SSB of the anchor cell the UE is suitable to use. However, for uplink synchronization when transitioning from an anchor cell to a non-anchor cell, the base station of the anchor cell does not know which SSB the UE is adapted to use for the non-anchor cell, at which time the base station should indicate to the UE multiple SSBs and their associated CFRA resource information. At this point, the base station of the non-anchor cell actually transmits the SSB and configures its associated CFRA resources in a beam sweeping (sweep) manner. Therefore, how to obtain one or more SSBs and their associated CFRA resource information for a UE is a challenge to be solved.

And a second problem: and is also a problem with 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, and accordingly, the UE can only use contention-based random access (Contention Based Random Access, CBRA) resources. Therefore, how to obtain information about using CFRA resources or CBRA resources by the UE is also a problem to be solved.

Problem three: problems with the bandwidth part.

It is necessary to determine which BWP to use when the UE transitions to a non-anchor cell. How to obtain information of which BWP to use on a non-anchor cell by a UE is also a problem to be solved.

Fourth problem: problems with switching target cells.

The UE needs to determine to which handover target cell to handover. How the UE gets to which handover target cell to handover is also a problem to be solved.

In view of the above technical problems, an embodiment of the present application provides an instruction information processing method, including:

for problem one, the base station may employ a first indication information (e.g., 1 bit) to indicate to the UE (the UE is available, even if there are multiple SSBs, possibly indicating to the UE only one SSB) whether the SSB and its associated CFRA resource for the non-anchor cell is one or more. When the SSB and its associated CFRA resource indicating the non-anchor cell are one, fall back to the traditional use of PDCCH order.

For problem two, the base station may employ second indication information (e.g., another 1 bit) to indicate to the UE whether to use CFRA resources or CBRA resource resources.

For problem one and problem 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 may not be used because the use of CBRA resource is indicated to the UE when "Random Access Preamble Index" is all 0 (nonsensical) in the conventional usage of PDCCH order. That is, the second indication information may not be used when the first indication information indicates that the SSB of the non-anchor cell and its associated CFRA resource are one. The first and second indication information are jointly encoded into a third indication information (e.g., 2 bits) taking 3 states or code points (codepoints) therein. For example, SSB and its associated CFRA resource for non-anchor cell in state 1 is one (legacy usage back to PDCCH order), SSB and its associated CFRA resource for non-anchor cell in state 2 is multiple and CFRA resource is used, SSB and its associated CFRA resource for non-anchor cell in state 3 is multiple and CBRA resource is used. Thus, one state can be saved and left for later use.

For problem three, the base station may indicate an index (index) or an Identification (ID) or a number (number) of the BWP used on the non-anchor cell to the UE using fourth indication information.

For problem four, the base station may use the fifth indication information to indicate the frequency point and/or Identification (ID) of the target non-anchor cell of the handover to the UE.

In the embodiment of the present application, the current cell may be used to represent the anchor cell, and the target cell to be converted may be used to represent the non-anchor cell. In addition, the handover is equivalent to the handover except for the special description "handover".

The following will explain in detail the embodiments.

Referring to fig. 2, fig. 2 is a flow chart of an instruction information processing method provided in an embodiment of the present application. In some embodiments, the indication information processing method may be applied in the UE.

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

The instruction information processing method comprises the following steps:

s201, according to the indication information, determining the SSB state and/or determining the random access resource state to perform uplink synchronization.

Illustratively, the states of the SSB include SSB state one and SSB state two.

Wherein the SSB states correspond one SSB. When the status of the SSB is SSB status one, the network device specifically indicates one SSB to the UE. SSB state two corresponds to one or more SSBs (not limited to one SSB). When the SSB state is SSB state two, the network device may instruct the plurality of SSBs to the UE to cause the UE to select an appropriate SSB and/or corresponding random access resource. It should be noted that, the SSB and the random access resource (e.g., random access preamble, PRACH occasion) may have a correspondence relationship. The correspondence may be preset or configured. Through the preset or configured corresponding relation, the SSB can be indicated only by indicating the SSB, or the SSB can be indicated only by indicating the random access resource, so that the signaling overhead is reduced.

Illustratively, the states of the random access resource include a random access resource state one and a random access resource state two. Random access resource status-corresponds to CFRA resource. When the state of the random access resource is one of the random access resource states, the network equipment specifically indicates the CFRA resource to the UE. The random access resource state two corresponds to CBRA resources. When the state of the random access resource is the random access resource state two, the network device may instruct the CBRA resource to the UE, so that the UE selects an appropriate random access preamble (preamble) and PRACH occasion (occalasion).

Specifically, one CFRA resource includes a set of PRACH occasions and a set of random access preambles, and the set of PRACH occasions and the set of random access preambles correspond to a set of SSBs. Alternatively, one CFRA resource includes a set of SSBs, a set of PRACH occasions, and a set of random access preambles. The PRACH time is the time-frequency resource of PRACH. When one SSB corresponds to multiple PRACH occasions, the PRACH mask may indicate one of the PRACH occasions. PRACH occasions may also be referred to as PRACH masks. In general, PRACH occasions may be represented by PRACH Mask indexes (PRACH Mask indexes), random access preambles may be represented by random access preamble indexes (Random Access Preamble Index), and SSBs may be represented by SSB indexes. It should be understood that "a group" herein includes both "a" and "a plurality. Unless specifically stated, a CFRA resource may represent one CFRA resource or multiple CFRA resources. In general, one random access preamble within one CFRA resource corresponds to one SSB. One PRACH occasion within one CFRA resource corresponds to one set of SSBs.

Specifically, one CBRA resource includes a set of PRACH occasions and a set of random access preambles, and the set of PRACH occasions and the set of random access preambles have a preset or configured correspondence with the SSB. It should be understood that the SSB herein may be a truly transmitted SSB. The CBRA resource configuration does not include SSB configuration due to the correspondence of the preset or configuration. It should be understood that "a group" herein includes both "a" and "a plurality. If not specifically stated, a CBRA resource may represent a CBRA resource or a plurality of CBRA resources.

In a possible embodiment, the indication information may be carried by any one of PDCCH order, GC-PDCCH or MAC-CE.

For example, in some embodiments, the indication information may be carried by PDCCH order, so that PDCCH order signaling may be reused, thereby saving signaling overhead and complexity.

In some embodiments, the above indication information may be carried by GC-PDCCH. The GC-PDCCH can be used for simultaneously sending the first indication information to a group of UE, so that signaling overhead is saved.

In some embodiments, the above indication information may be carried by the MAC-CE. The UE can feed back whether the PDSCH is successfully decoded or not (through HARQ-ACK signaling) by using MAC-CE carrying, so that misunderstanding of both the base station and the UE is avoided, and delay is reduced.

The UE may determine the SSB state and/or determine the random access resource state according to the indication information to perform uplink synchronization.

Illustratively, the UE may obtain different information according to the above indication information to cope with several different scenarios:

one SSB and its corresponding CFRA resource (conventional);

a plurality of SSBs and their corresponding CFRA resources;

one SSB and uses CBRA resources (when CBRA resources are already configured, no indication of random access resources may be needed);

Multiple SSBs and uses CBRA resources (when CBRA resources are already configured, there may be no need to indicate random access resources).

According to the indication information processing method, the UE can determine the SSB state and/or determine the random access resource state according to the indication information, so that the UE is facilitated to cope with various uplink synchronization scenes.

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

Wherein 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 may use the first indication information to indicate to the UE that SSB of the non-anchor cell and its associated CFRA resource are one or more, thereby solving the problem one.

Alternatively, the first indication information may be 1 bit, which may save bit overhead.

In some embodiments, the first indication information may be carried by PDCCH order, so that PDCCH order signaling may be reused, thereby saving signaling overhead and complexity.

In some embodiments, the first indication information may be carried by GC-PDCCH. The GC-PDCCH can be used for simultaneously sending the first indication information to a group of UE, so that signaling overhead is saved.

In some embodiments, the first indication information may be carried by a MAC-CE. The UE can feed back whether the PDSCH is successfully decoded or not (through HARQ-ACK signaling) by using MAC-CE carrying, so that misunderstanding of both the base station and the UE is avoided, and delay is reduced.

In some embodiments, when the first indication information indicates that the state of the SSB is SSB state one, a field of the PDCCH order is not escape (i.e., a legacy meaning).

When the first indication information indicates that the state of the SSB is SSB state two, a field of the PDCCH order is escape (i.e., a non-legacy meaning).

When the first indication information indicates that the SSB state is SSB state two, the "SSB index (SSB index)", "random access preamble index", and "PRACH mask index" in the PDCCH order are not valid (or are reserved). Thus, when the first indication information indicates that the state of the SSB is SSB state two, the field that is no longer needed can be diverted to a new field.

Based on the descriptions in the above embodiments, in some embodiments of the present application, the above indication information is second indication information; the UE may determine, according to the second indication information, that the random access resource state is a random access resource state one or a random access resource state two.

The random access resource state one corresponds to the CFRA and the random access resource state two corresponds to the CBRA resource.

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

It will be appreciated that when the above first indication information indicates that the status of SSB is SSB status one, the UE may not parse the second indication information, because the field of PDCCH order is not escape (i.e. the conventional meaning) at this time, in which the existing method indicates whether to use CFRA resource or CBRA resource ("Random Access Preamble Index" field is all 0).

Alternatively, the second indication information may be 1 bit, which may save bit overhead.

In some embodiments, the second indication information may be carried by PDCCH order, so that PDCCH order signaling may be reused, thereby saving signaling overhead and complexity.

In some embodiments, the second indication information may be carried by a GC-PDCCH. The GC-PDCCH can be used for simultaneously sending the first indication information to a group of UE, so that signaling overhead is saved.

In some embodiments, the second indication information may be carried by a MAC-CE. The UE can feed back whether the PDSCH is successfully decoded or not (through HARQ-ACK signaling) by using MAC-CE carrying, so that misunderstanding of both the base station and the UE is avoided, and delay is reduced.

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

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

Wherein SSB state one corresponds to one SSB and SSB state two corresponds to one or more SSBs (not limited to one SSB). The random access resource state one corresponds to the CFRA and the random access resource state two corresponds to the CBRA resource.

Wherein, when the first indication information indicates that the SSB of the non-anchor cell is one, the second indication information may not be used because the CBRA resource is indicated to the UE when "Random Access Preamble Index" is all 0 (meaningless) in the conventional usage of PDCCH order. That is, when the above-described first indication information indicates that the SSB of the non-anchor cell is one, the second indication information may not be used. This means that the first indication information and the second indication information can be encoded jointly into the third indication information to solve the problem one and the problem two at the same time.

Alternatively, the third indication information may be 2 bits, which may save bit overhead.

Alternatively, the third indication information may include 3 states or code points (codepoints). In this way, one state can be saved and left for later use, thereby improving the forward compatibility and flexibility of the system.

The third indication information may indicate the following states:

state 1: indicating SSB state one;

state 2: indicating an SSB state II and a random access resource state I;

state 3: and indicating an SSB state II and a random access resource state II.

In some embodiments, SSB and its associated CFRA resources, state 1 above being a non-anchor cell, are one (legacy usage back to PDCCH order); the SSB and its associated CFRA resources in which state 2 is a non-anchor cell are plural and CFRA resources are used; the SSB, which is a non-anchor cell in state 3 above, is one or more and uses CBRA resources.

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

In some embodiments, the third indication information may be carried by GC-PDCCH. The GC-PDCCH can be used for simultaneously sending the first indication information to a group of UE, so that signaling overhead is saved.

In some embodiments, the third indication information may be carried by a MAC-CE. The UE can feed back whether the PDSCH is successfully decoded or not (through HARQ-ACK signaling) by using MAC-CE carrying, so that misunderstanding of both the base station and the UE is avoided, and delay is reduced.

The indication information processing method provided in the embodiments of the present application may include most of scenarios, that is, a scenario in which one SSB and its corresponding CFRA resource (in a conventional manner), a plurality of SSBs and its corresponding CFRA resource, one or more SSBs, and CBRA resources are used (no indication of random access resources is needed at this time).

Alternatively, the fourth indication information may be carried by any one of PDCCH order, GC-PDCCH, or MAC-CE.
