Description

Resource mapping method, network equipment and base station
Technical Field
The present invention relates to the field of communications, and in particular, to a method for resource mapping, a network side device, and a base station.
Background
With the development of wireless communication technology and the increasing demand for communication by users, fifth generation mobile communication (5th Generation,5G) technology has become a trend in future network development in order to meet the higher, faster and newer communication demands.
A 5G communication system is considered to be implemented in a higher and wider frequency band (e.g., above 3 GHz) in order to achieve higher data rates. The high-frequency communication is characterized by relatively serious path loss and penetration loss, and is closely related to the atmosphere in the process of space propagation. According to the characteristic of extremely short wavelength of high-frequency signals, a large number of small antenna arrays can be applied, so that the beam forming technology can obtain more accurate beam directions, the coverage capability of the high-frequency signals is improved by the advantage of the narrow beam technology, the transmission loss is compensated, and the method is a great characteristic of high-frequency communication.
In a conventional long term evolution (Long Term Evolution, LTE) system, a control channel region and a data channel region are independent, and the control channel region is only used for transmitting a control channel and its associated demodulation reference signals, but cannot be used for transmitting a data channel. Since the bandwidth of the system is very large in most cases in the 5G communication system, the bandwidth is far greater than the maximum system bandwidth of LTE, for example, the maximum possible GHz level. In the LTE system, the resources of the downlink control channel are scattered and distributed over the whole system bandwidth, but in order to reduce the blind detection complexity and the terminal power consumption of the terminal in the 5G NR (New RAT) system, the network side often configures one or more control resource sets for the terminal, where each control resource set is formed by one or more physical resource blocks (physical resource block, PRBs) in the frequency domain, and is formed by one or more symbols in the time domain, where one control channel performs resource mapping and transmission only on one control resource set, which is essentially intended to limit the blind detection range of the control channel, and is embodied in one subband in the frequency domain instead of the whole bandwidth. In addition, considering that the number of beams that can be simultaneously transmitted on each symbol in the beamforming system is limited, omni-directional transmission cannot be supported, and thus, there may be a lot of resources in the NR control region that are idle.
In order to increase resource utilization, the third generation partnership project (3rd Generation Partnership Project,3GPP) has proposed in discussion about 5G communication systems (e.g., NR) the notion that it should be supported that data channels can dynamically use control channel region resources. However, since the resource allocation and transmission mechanism of the control channel are very different from those of the data channel, for example, the resource allocation unit of the control channel is a control channel unit (Control Channel Element, CCE), while the resource scattering is in units of resource element groups (Resource Element Group, REG), and the minimum basic unit of the resource allocation of the data channel is one PRB in the frequency domain and one symbol in the time domain. Although, the 3GPP further passes the REG of the control region in the discussion as one PRB in the frequency domain and one symbol in the time domain, which lays a foundation for implementing the reuse of the control region resources for the data channel. However, since the control channel supports both centralized and discrete transmission of resources, the remaining resources in the control channel region tend to be irregularly and discretely distributed. Among them, the most direct and highest resource utilization method is to dynamically inform terminals of all unused REG or CCE resources in one control region, but this results in a very large dynamic signaling overhead. Another simpler method is to indicate to the terminal the starting position of the data channel, which can be located in the control channel region, this method is the simplest, has little standardization effort, and little signaling overhead, but has a low resource utilization rate, and once one control channel is not known to the terminal, all the resources on the symbol corresponding to the control channel cannot be utilized by the data channel of the terminal. Therefore, how to use the control channel area resource for the data channel to achieve a higher resource utilization rate with a smaller signaling overhead has become a problem to be solved in the 5G communication system.

Third embodiment
Fig. 2 is a first resource mapping diagram of a method for mapping resources according to an embodiment of the present invention, as shown in fig. 2, a frequency domain range of a data channel of UE1 is a range defined by a PDSCH1 of a vertical physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) in the figure, and DCI1 is used to indicate a resource allocation situation of the data channel of UE1, where CORESET1 is a control resource set (Control Resource Set, CORESET) configured by a base station to UE 1. Also within the PDSCH1 frequency domain is a core 2, which is not a control resource set allocated to UE1, but a control resource set allocated to other users (e.g., UE 2), and is mainly used to transmit downlink control information (Downlink Control Information, DCI) of other users. The duration of the control resource sets CORESET1 and CORESET2 in the time domain is 2 OFDM symbols. In the embodiment of the present invention, CORESET1 may be understood as a first resource region, and CORESET2 may be understood as a second resource region.
The base station specifies that only the control channel or the common control channel of UE1 is allowed to be transmitted in the control resource set CORESET1 allocated to UE1, and transmits the data channel PDSCH1 of UE1 in the remaining resources of the control resource set other than the control channel or the common control channel used for transmitting UE 1. As shown in fig. 2, on the base station side, PDSCH1 is mapped into the remaining resources except DCI1 in CORESET1 and into the data channel resource region. On the receiving side, the UE1 can determine whether there is a dedicated control channel or a common control channel in the control resource set CORESET1 through blind detection, determine a specific resource position, and receive the data channel PDSCH1 corresponding to the DCI1 at the remaining resource positions in the control channel and in the data channel resource region.
Since control resource set CORESET2 is a non-configured control resource set for UE1, UE1 is not aware of CORESET2 and whether there is DCI for other users in it and the specific resource location of the DCI. Therefore, on the base station side, the base station indicates to the UE1 the starting symbol position of the PDSCH1 in CORESET2 through signaling, and the starting symbol of the PDSCH1 in CORESET2 in fig. 2 is the 2 nd OFDM symbol, that is, the PDSCH1 performs resource mapping from the 2 nd OFDM symbol in CORESET 2. On the receiving side, UE1 receives data channel PDSCH1 according to the CORESET2 resource map described above.
Fourth embodiment
Fig. 3 is a second resource mapping diagram of a method for mapping resources according to an embodiment of the present invention, as shown in fig. 3, a frequency domain range of a data channel of UE1 is a range defined by a vertical PDSCH1 in the figure, and DCI1 is used to indicate a resource allocation situation of the data channel of UE1, where CORESET1 is a control resource set configured by a base station to UE 1. Other users' DCIs are also allowed in CORESET1, for example DCI2 in FIG. 3 is the DCI of UE 2. Also within the PDSCH1 frequency domain is a core 2, which is not a set of control resources allocated to UE1, but a set of control resources allocated to other users, e.g., UE3, primarily for transmitting DCI for other users (except UE 1). The duration of the control resource sets CORESET1 and CORESET2 in the time domain is 2 OFDM symbols.
The base station defines that the control resource set CORESET1 allocated to the UE1 allows the DCI of other users to be transmitted in addition to the DCI of the UE1, but it is necessary to sequentially transmit the DCI of a plurality of users in the order of resources from the first frequency domain to the second time domain, from the low frequency domain to the high frequency domain, and from the first time domain to the second time domain. For example, in fig. 3, on the base station side, DCI2 of UE2 needs to be placed before DCI1 of UE1, and then data channel PDSCH1 of UE1 is transmitted on resources after DCI1 of CORESET 1. On the receiving side, UE1 obtains the specific resource location of its own control channel DCI1 in control resource set CORESET1 through blind detection, and considers that the data in data channel PDSCH1 of UE1 is mapped on the resources following DCI1 in CORESET 1.
Since control resource set CORESET2 is a non-configured control resource set for UE1, UE1 is not aware of CORESET2 and whether it has other users' DCIs and the specific resource locations of the DCIs. Thus, on the base station side, the base station indicates to UE1 the starting symbol position of PDSCH1 in CORESET2 by signaling, as in fig. 3, the starting symbol of PDSCH1 in CORESET2 is the 3 rd OFDM symbol, i.e. PDSCH1 performs resource mapping in CORESET2 starting from the 3 rd OFDM symbol. Here, the 3 rd OFDM symbol is located outside CORESET2, i.e., in the data channel resource region, and thus data channel mapping is not performed in CORESET 2. On the receiving side, UE1 receives data channel PDSCH1 according to the CORESET2 resource map described above.
It should be noted that, when there are multiple proprietary control channels of UE1 in the current scheduling time unit, the arrangement order between these multiple proprietary control channels needs to be specified, otherwise, UE1 cannot determine whether the DCI currently detected blindly is the last DCI in the current scheduling time unit. For example, the terminal-specific control channels include: 1) A terminal-specific control channel for scheduling uplink data traffic in a current scheduling time unit; 2) A terminal-specific control channel for scheduling downlink data traffic in a current scheduling time unit; 3) A terminal-specific control channel for scheduling uplink data traffic in a scheduled time unit subsequent to the current scheduled time unit; 4) A terminal-specific control channel for scheduling uplink data traffic in a scheduled time unit subsequent to the current scheduled time unit. The four terminal-specific control channels are mapped sequentially in a predefined order. Preferably, when all of the four control channels are present in the current schedule time unit, the dedicated control channel 2 is mapped last).
Fifth embodiment
The network side (or base station) sets a plurality of resource mapping modes for the appointed resource region, and indicates the mapping mode currently used to the terminal through signaling. Preferably, the base station indicates the currently used resource mapping mode to the terminal through physical layer dynamic signaling.
By way of example, the various resource mapping approaches may include: one or more of a first resource mapping manner, a second resource mapping manner, a third resource mapping manner, a fourth resource mapping manner and a fifth resource mapping manner in the first embodiment.
For example, the plurality of resource mapping modes includes a mode one and a mode two. Firstly, blind detection is carried out on a control resource set configured to a terminal, DCI corresponding to the terminal and a specific resource position of the DCI are determined, and resources of a mapping data channel are determined; the manner of resource mapping is determined by the PDSCH starting symbol (i.e., the data channel of the terminal is mapped from the PDSCH starting symbol in the set of control resources allocated to the terminal, except for the DCI of the terminal and the remaining resources of the resources occupied by the common control channel). The first method is preferably the second resource mapping method in the first embodiment, and the second method is preferably the third resource mapping method in the first embodiment.
In actual implementation, the base station indicates the starting symbol position of PDSCH1 to user UE 1. Meanwhile, the base station is further configured to indicate whether the data channel resource mapping should be performed in the first mode or the second mode in the control resource set configured to the UE1 by adding 1 bit in the DCI1 of the UE 1. Therefore, the base station can select any mapping mode according to the actual situation.
For example, as shown in fig. 3, when there is no resource overlap between the control resource set CORESET1 configured to the terminal UE1 and the control resource set CORESET2 not configured to the terminal UE1, the base station performs resource mapping of the UE1 data channel PDSCH1 to the CORESET1 in a manner, and the base station indicates to the terminal UE1 that the resource mapping is performed in a manner to the CORESET1 configured to the terminal through signaling, so that the UE1 knows that the data channel PDSCH1 is performed in a manner to the CORESET1 and receives the data channel in a manner to the CORESET 1.
Fig. 4 is a third resource mapping diagram of a resource mapping method in an embodiment of the present invention, as shown in fig. 4, when there is a partial resource overlap between the control resource set CORESET1 configured to the terminal UE1 and the control resource set CORESET2 not configured to the UE1, if the resource mapping is performed in the first manner, all DCI must be placed on the overlapping portion resources of the two control resource sets, which has a significant limitation on the scheduling of the base station, especially when the overlapping portion resources are not too many.
Fig. 5 is a fourth resource mapping diagram of a method for resource mapping in an embodiment of the present invention, as shown in fig. 5, in order not to cause too great limitation on scheduling of a base station, the base station performs resource mapping on CORESET1 in a second mode, and the base station indicates to the terminal UE1 that resource mapping is performed on CORESET1 in the second mode through signaling, so that the UE1 receives a data channel in the second mode after knowing that the data channel PDSCH1 performs resource mapping in the second mode.
Since control resource set CORESET2 is a non-configured control resource set for UE1, UE1 is not aware of CORESET2 and whether it has other users' DCIs and the specific resource locations of the DCIs. Therefore, on the base station side, the base station indicates to the UE1 the starting symbol position of the PDSCH1 in CORESET2 through signaling, as in fig. 4 and 5, the starting symbol of the PDSCH1 in CORESET2 is the 2 nd OFDM symbol, i.e. the PDSCH1 performs resource mapping in CORESET2 starting from the 2 nd OFDM symbol. On the receiving side, UE1 receives data channel PDSCH1 according to the CORESET2 resource map described above.
Note that, when the control resource set CORESET1 allocated to the terminal UE1 is the resource mapping mode two, the base station needs to signal to the UE1 a starting symbol position (referred to as a starting symbol position 1) of the PDSCH1 in CORESET1, and there is also a starting symbol position (referred to as a starting symbol position 2) on the control resource set CORESET2 not allocated to the UE 1. The two initial symbol positions may be the same or different, and when the two initial symbol positions are the same, that is, the initial symbol position of the UE1 defaults to the control resource set CORESET1 is the initial symbol position of CORESET2, the base station only needs to uniformly notify information of one initial symbol position through signaling. When the two initial symbol positions are different, the base station needs to respectively notify a plurality of initial symbol positions through signaling, and the plurality of initial symbol positions can respectively correspond to symbols on one sub-band by taking the sub-band as a unit, or respectively correspond to symbols on different control resource sets. In the embodiment of the present invention, the starting symbol position may be the starting symbol position of the data channel resource mapping on CORESET1 and CORESET2, and the starting symbol position is also dynamically notified through the physical layer signaling.
In practical implementation, the network side may indicate to the terminal whether switching between multiple mapping modes is enabled through higher layer signaling, when the signaling indicates "not enabled", the base station maps the data channel according to the signaling indication of the initial symbol position of the PDSCH, and the terminal knows that the data channel starts to map from the initial symbol position of the PDSCH indicated by the base station, and starts to receive the data channel from the initial symbol position.
Sixth embodiment
The network side (or the base station) sets a plurality of resource mapping modes for the designated resource area, and indicates the currently used mapping mode to the terminal through signaling, and when the base station configures a plurality of control resource sets for the terminal, different resource areas of the plurality of control resource sets may adopt the same or different mapping modes. Preferably, the base station indicates the mapping manner currently used to the terminal through physical layer dynamic signaling.
Fig. 6 is a fifth resource mapping diagram of a resource mapping method in an embodiment of the present invention, as shown in fig. 6, where CORESET1 and CORESET2 are two control resource sets configured for UE1, where the duration of CORESET1 in the time domain is 2 symbols, the duration of CORESET2 in the time domain is 3 symbols, and there is a partial resource overlap between CORESET2 and CORESET 1.
In practical implementation, when there is a control channel or a Common control channel of UE1 in CORESET2, as shown in fig. 6, there are two control channels of scheduling users in CORESET1, namely, a control channel DCI1 of UE1 (DCI 1 is used for scheduling data channel PDSCH1 of UE 1) and a control channel DCI2 of other users, and there is one control channel DCI3 and a Common control channel Common DCI of scheduling other users in CORESET 2. Since there are control channels (i.e., control channel DCI1 and Common control channel DCI of UE i) that can be detected by UE blindly in CORESET1 and CORESET2, UE1 knows the resource situation occupied by CORESET1 and CORESET2 respectively, for example, DCI1 in CORESET1 can be received by UE1 and Common DCI in CORESET2 can be received by UE1, so resource mapping can be performed in CORESET1 and CORESET2 in a first manner. Signaling indicates to UE1 that resource mapping is performed in both CORESET1 and CORESET2 in a manner one. Specifically, a predefined mapping order is required to be set for the control channel, in CORESET1, the base station sorts DCIs of all users in a predefined manner, DCI2 of other users is placed before DCI1 of UE1, and data channel PDSCH1 of UE1 is mapped in the remaining resources after DCI1 except the resources occupied by CORESET 2; in COERESET2, the base station sorts DCIs of all users according to a predefined mode, places DCIs of other users in front of Common DCIs, and maps a data channel PDSCH1 of UE1 in the residual resources after the Common DCIs; at the receiving end, after receiving the indication of the resource mapping mode of the base station, the UE1 knows that PDSCH1 is mapped in the remaining resources except CORESET2 after DCI1 in CORESET1, PDSCH1 is mapped in the resources after Common DCI in CORESET2, and receives the data channel PDSCH1 according to the above mapping mode and the indication of other information of DCI 1.
In practical implementation, when there is no control channel and no common control channel of the target user in CORESET2, the base station indicates to the terminal that its data channels are mapped in mode one on resources other than CORESET2 in CORESET1, and that data channels are mapped in mode two in other control resource sets (including CORESET 2).
Fig. 7 is a sixth resource mapping diagram of a method for mapping resources according to an embodiment of the present invention, as shown in fig. 7, since CORESET2 does not have a control channel or a common control channel of UE1, it is required to map data channels in a second manner, where the data channels are mapped from the 2 nd symbol on CORESET2, and the data channels are mapped in a first manner on resources other than CORESET2 in CORESET 1. The base station informs the UE1 through signaling that the initial symbol position of the data channel for resource mapping in CORESET2 is the 2 nd OFDM symbol.
Optionally, the base station may select an appropriate data channel mapping manner for the resource region corresponding to the control resource set configured to the target terminal according to different mapping conditions of CORESET1 and CORESET2, transmission conditions of the control channel, channel quality environment, and the like, and indicate the mapping manner to the terminal through signaling. The different resource region division may be performed according to different control resource sets, or according to whether a control channel or a common control channel of the target user exists/is received in the control resource sets, or whether the control channel or the common control channel of the target user exists/is received, or the remaining resources except other control resource sets (such as CORESET2 in fig. 6 and 7) configured for the target user in the control channel region corresponding to the data channel frequency domain in the remaining resources except the foregoing resources, and so on. The different region divisions should preferably be predefined.
In the embodiment of the invention, the resource mapping of the data channel is performed in N resource areas according to the resource mapping mode corresponding to each resource area, wherein N is a positive integer. Compared with the prior art, the resource mapping of the data channel is carried out by different resource areas according to the corresponding resource mapping mode, so that the dynamic use of the control channel area resource by the data channel can be realized, the signaling overhead is reduced, and the resource utilization rate of the control channel area is ensured.
