Detailed Description
In the 5G system, a synchronization signal, a broadcast channel, is transmitted in a synchronization signal block (SS-block), and a Beam Sweeping (Beam Sweeping) function is introduced. Primary Synchronization Signal (PSS), Secondary Synchronization Signal (SSS), and Physical Broadcast Channel (PBCH) are in a Synchronization Signal block. Each synchronization signal block can be regarded as a resource of one beam (analog domain) in the beam sweeping process. A plurality of sync signal blocks constitute a sync signal burst (SS-burst). The synchronization signal bursts constitute a set of synchronization signal bursts (SS-burst-set). The synchronization signal block is repeatedly transmitted on different beams, which is a beam scanning process, and through the training of beam scanning, the user equipment can sense on which beam the received signal is strongest.
The time domain position of the L synchronization signal blocks within a 5ms window is fixed. The indices of the L synchronization signal blocks are arranged consecutively in time domain positions, from 0 to L-1. The transmission time instant of a synchronization signal block within this 5ms window is fixed and the index is also fixed.
As mentioned above, at present, for the common control message, the configuration of the corresponding control resource group cannot be adapted to the flexibility requirement of 5G scanning beam deployment. The following is a specific example of the configuration of the control resource group of the current paging message.
From the physical channel perspective, the page includes a paging control message and a paging message. The paging Control message is Downlink Control information of a Physical Downlink Shared Channel (PDSCH) that is scheduled to be carried in a PDCCH. A User Equipment (UE) determines whether it is necessary to decode a paging message in a corresponding PDSCH by monitoring paging control information. The paging message is carried in the PDSCH, is scheduled by the paging control information, and includes information such as an identifier of the paged user equipment.
The paging configuration includes a timing configuration. The timing configuration means that the base station selects a proper time to send a paging message to the user equipment according to the parameters, and meanwhile, the user equipment monitors paging control information at the proper time according to the parameters and receives the paging message. The timing configuration mainly includes a Paging Frame (PF) and a Paging Occasion (PO). In LTE, the unit of a paging Frame is one Radio Frame (Radio Frame), and the unit of a paging occasion is one subframe (subframe).
Generally, the System Frame Number (SFN) of a paging Frame is determined by a UE identity (UE Identification, marked with UE _ ID in LTE protocol), a paging cycle (base station configuration parameter, marked with T in LTE protocol), and a paging density (total Number of possible paging frames in one paging cycle, marked with N in LTE protocol). In the LTE protocol, the PF satisfies the relationship in the following specific formula:
SFN mod T＝(T div N)*(UE_ID mod N) (1)
where SFN represents the system frame number of the paging frame, N ═ min (T, nB), and nB is a parameter configured by the base station.
Generally, the subframe of the paging occasion is determined by the LTE system type (frequency division duplex (FDD) or Time Division Duplex (TDD)), the parameter Ns and i _ s together. The PO satisfies the following specific formula:
i_s＝floor(UE_ID/N)mod Ns (2)
where i _ s denotes the index of the paging subframe, Ns denotes how many paging subframes are in each PF, and Ns ═ max (1, nB/T).
Paging is a packet paging mode, i.e. in a PO it may be considered by the user equipment to belong to a group, which is UE _ ID related. This can be seen from the PF/PO equation.
In 5G systems, a multi-beam functionality is introduced, so that common control messages can be transmitted in a multi-beam manner, i.e. in a beam sweeping (beam sweeping) manner on a plurality of time-divided resources with different beams. The time division resources are related to the number of beams in the current cell. The number of beams configured in different cells may be different, which results in different time division resources to be configured in different cells, and the above configuration scheme of the paging occasion cannot support the flexibility requirement of 5G scanning beam deployment.
However, at present, for the 5G system, there is no configuration scheme capable of flexibly configuring the time division resources corresponding to the common control message including the paging message.
To solve the foregoing problems, an embodiment of the present invention provides a method for configuring a control resource group, including: and sending configuration information of a first type of control resource group set to the user equipment, wherein the first type of control resource group set is a set of control resource groups which the user equipment needs to monitor in an idle state, so that the flexible configuration of resources corresponding to the common control message can be realized, and the user equipment can realize the effective monitoring of the common control message in the idle state. A Control Resource Set (core Set) in the first type of Control Resource Set is a Resource Set for bearing a Physical Downlink Control Channel (PDCCH).
By adopting the scheme of the embodiment of the invention, resources corresponding to the public control messages including the paging messages can be configured, so that the user equipment can realize effective monitoring on the public control messages including the paging messages in an idle state.
In order to make the aforementioned objects, features and advantages of the embodiments of the present invention more comprehensible, specific embodiments accompanied with figures are described in detail below.
Referring to fig. 1, an embodiment of the present invention provides a method for configuring a control resource group, where the method includes the following steps:
s11, sending configuration information of a first type of control resource group set to the user equipment, wherein the first type of control resource group set is a set of control resource groups which the user equipment needs to monitor in an idle state.
It should be noted that, for convenience of description, in the embodiment of the present invention, a set of control resource groups that the user equipment needs to monitor in an idle state is referred to as a "first type of control resource group set," where the "first type" is not used to limit a specific order or function of the control resource group set, and only plays a role of identification.
In a specific implementation, one control resource group in the first type of control resource group set may correspond to a control resource group of one unit slot. The unit timeslot may be a timeslot (slot) or a mini-slot (mini-slot) defined in a 3GPP protocol, or a timeslot of another duration defined according to a specific communication environment. In an embodiment of the present invention, one control resource group in the first type of control resource group set is default to correspond to a control resource group of one slot (slot).
In a specific implementation, the first type of control resource group set may be a set of paging-related control resource groups to which the user equipment needs to listen in an idle state. In an embodiment of the present invention, a subset of the first set of control resource groups is a Paging Occasion (PO).
In a specific implementation, the paging occasion may be set to be associated with a corresponding ue identifier, so that the corresponding ue can quickly identify its corresponding paging occasion.
In a specific implementation, the control resource group in the paging timer has a one-to-one association relationship with the actually transmitted synchronization signal block. In an embodiment of the present invention, the association relationship includes a spatial Quasi Co-Located (QCL) relationship.
In an embodiment of the present invention, the configuration Information of the first type of control resource set is sent through a Remaining Minimum System Information (RMSI).
Through the configuration, the user equipment can monitor the control resource groups in the first type of control resource group set to acquire the control information.
By adopting the technical scheme of the embodiment, the configuration information containing the first type of control resource group set is sent to the user equipment, and the first type of control resource group set is the set of control resource groups which the user equipment needs to monitor in an idle state, so that the flexibility of 5G scanning beam deployment can be sufficiently supported, the time division resources corresponding to the common control message can be flexibly configured, and the user equipment can effectively monitor the downlink control channel in the idle state. In addition, because one control resource group in the first type of control resource group set corresponds to the control resource group of one unit time slot, the relationship between the unit time slot where the control resource group is located and the unit time slot where the synchronization signal block is located is easily established, so that the user equipment can achieve a better effect of monitoring the control resource group through beam training.
In a specific implementation, the first type of control resource group set generally appears periodically, and in the embodiment of the present invention, to implement flexible configuration of a control resource group, the flexible configuration may be implemented by increasing a configuration dimension of the control resource group, for example, the configuration information may indicate an appearance period, an offset, and an index within the period of the first type of control resource group set.
In the embodiment of the present invention, a person skilled in the art may flexibly configure the occurrence period, the offset, and the index in the period of the first type control resource group set according to the user equipment itself and the condition of the control resource group in the cell where the user equipment is located.
In order to make the embodiment of the present invention better understood and implemented by those skilled in the art, how the embodiment of the present invention implements flexible configuration of control resource groups is described below by some specific application scenarios and specific schemes.
In a specific implementation, the period may be L radio frames, M subframes, or N unit slots, where M, N are integers greater than or equal to 1.
In a specific implementation, the offset may be L2 radio frames or M2 subframes or N2 unit slots, where M2 and N2 are both integers greater than or equal to 1.
There may be different implementations for indexing within a cycle, which are described in detail below by way of example.
In an embodiment of the invention, the index is given directly by a bitmap. The index of the first type of control resource group set in one period is directly given by adopting a bitmap mode, so that the control resource groups in the first type of control resource group set can be configured on any slot (slot) or micro slot (mini-slot), and great flexibility is achieved. For example, the bitmap corresponding to the configuration information is: 101010, the index positions of the unit time slots corresponding to the control resource groups in a radio frame are indicated as 1, 3 and 5.
In another embodiment of the present invention, the control resource groups in the first type of control resource group set are grouped, and the index may have multiple implementations. For example, the index may be given by the inter-group bitmap and the intra-group bitmap, or by the number of groups and the intra-group bitmap, or by the inter-group bitmap and the number of control resource groups within a group, or by the number of groups and the number of control resource groups within a group. By adopting the grouping setting mode, the flexibility of controlling the configuration of the resource groups can be improved to a certain extent, and the overhead of configuration information can be reduced. In a specific implementation, the base station generally supports the following deployment modes: the beams in the beam scanning are grouped, and the number of the beams in all the groups is consistent, so that the user equipment can achieve a better effect of monitoring and controlling the resource groups through beam training. For example, one group may be one unit slot. For another example, each group in the control resource group set is N consecutive unit slots, N is an integer, and N > 1, for example, N takes a value of 2.
In another embodiment of the present invention, the index is given corresponding to the index of the unit slot in which the actually transmitted synchronization signal block is located.
In another embodiment of the present invention, the index may be an optional unit slot, wherein the optional unit slot. The selectable unit timeslots may be all downlink unit timeslots or a subset of unit timeslots having downlink transmission sections in the period, and all downlink unit timeslots or unit timeslots having downlink transmission sections in the period may be given by signaling.
In this embodiment of the present invention, the optional unit timeslot may be all downlink unit timeslots in the period, or may be a unit timeslot having a downlink transmission part. All downlink unit time slots or unit time slots with downlink transmission parts in the period are given by signaling.
As described above, the unit timeslot may be a timeslot or a micro timeslot defined by a 3GPP standard protocol, or a timeslot with other duration, which may be specifically set according to needs. When the unit time slot is a micro time slot, the configuration information may also report the symbol number of the micro time slot.
For example, the positions of the control resource groups in the first type of control resource group set are L consecutive optional time slots which occur periodically, and the occurrence period and the offset can be indicated through signaling. Where the offset is for a starting location, such as the first slot in the first SFN. By adopting the scheme, the position coupling of the first type control resource group set and the synchronization signal block is small, so that the flexibility is good, and meanwhile, the signaling overhead is small because L synchronization signal blocks which continuously appear can be regarded as a whole. In an embodiment of the invention, a typical value of N is taken to be 2.
In a specific implementation, RMSI signaling may be employed as the signaling indicating the optional unit slot.
In a specific implementation, in addition to configuring the same information as paging through the control resource group set, other control resource information groups may be configured. In an embodiment of the present invention, the configuration information further includes information indicating a PDSCH scheduled by a PDCCH in the first type control resource group set. Wherein the information indicating PDSCH scheduled by PDCCH in the first type control resource group set may include at least one of: duration of the scheduled PDSCH, frequency domain resource information where the scheduled PDSCH is located.
For convenience of description, the above-described embodiment of the method for controlling resource group configuration is mainly described from the base station side, and for better understanding and implementing the present invention for those skilled in the art, the following describes in detail the corresponding operations adopted by the user equipment in the process of controlling resource group configuration according to the embodiment of the present invention.

In a specific implementation, the first type of control resource group set may be a set of paging-related control resource groups to which the user equipment needs to listen in an idle state.

In addition, because one control resource group in the first type of control resource group set corresponds to a control resource group of one unit time slot, the relationship between the unit time slot where the control resource group is located and the unit time slot where the synchronization signal block is located is easily established, so that the user equipment can achieve a better effect of monitoring the control resource group through beam training.
