Description
Technical Field
The present invention relates to the field of communications, and in particular, to a resource mapping method, a network side device, and a base station.
Background
With the development of wireless communication technology and the increasing demand of users for communication, fifth Generation mobile communication (5th Generation, 5G) technology has become a trend of future network development in order to meet higher, faster and more recent communication needs.
5G communication systems are known to be implemented in higher and wider frequency bands (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 has close relation with the atmosphere when in space transmission. According to the characteristic that the wavelength of the high-frequency signal is extremely short, a large number of small antenna arrays can be applied, so that the beam forming technology can obtain a more accurate beam direction, the coverage capability of the high-frequency signal 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 (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 a demodulation reference signal related thereto, but not used for transmitting a data channel. In the 5G communication system, the bandwidth of the system is usually very large, and is much larger than the maximum system bandwidth of LTE, for example, the maximum system bandwidth can reach GHz level. In an LTE system, resources of downlink control channels are distributed in a scattered manner over the entire system bandwidth, but in a 5G NR (New RAT) system, in order to reduce the terminal blind detection complexity and terminal power consumption, a network side often configures one or more control resource sets for a terminal, where each control resource set is composed of one or more Physical Resource Blocks (PRBs) in a frequency domain and one or more symbols in a time domain, where one control channel performs resource mapping and transmission only on one control resource set, and it is actually intended to limit the blind detection range of the control channel, which is reflected in the frequency domain as a subband, rather than the entire bandwidth. In addition, considering that the number of beams that can be simultaneously transmitted on each symbol in the beamforming system is limited, and omni-directional transmission cannot be supported, a large amount of resources may be idle in the NR control region.
In order to improve resource utilization, the third Generation partnership project (3 GPP) has proposed in the discussion about 5G communication systems (e.g., NR) that should support the dynamic use of control channel region resources by data channels. However, since the Resource allocation and transmission mechanism of the Control channel are different from those of the data channel, for example, the Resource allocation unit of the Control channel is a Control Channel Element (CCE), while the Resource scattering is in units of Resource Element Groups (REGs), and the minimum basic unit of Resource allocation of the data channel is one PRB in the frequency domain and one symbol in the time domain. Although, in the discussion of the 3GPP, the REG in the control region is further defined as one PRB in the frequency domain and one symbol in the time domain, which lays a foundation for implementing reuse of the resources in the control region for the data channel. However, since the control channel supports both the resource-localized transmission and the resource-discrete transmission, the remaining resources in the control channel region are often distributed irregularly and discretely. Among them, the most direct and highest resource utilization method is to dynamically notify all unused REG or CCE resources in one control region to the terminal, but this results in a very large dynamic signaling overhead. Another simpler method is to indicate the starting position of the data channel to the terminal, where the starting position may be located in the control channel region, and this method is simplest, has a small standardization workload and a small signaling overhead, but has a low resource utilization rate, and once one control channel is not aware of the terminal, all 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 region resource for the data channel can achieve a high resource utilization rate with a small signaling overhead has become an urgent problem to be solved in the 5G communication system.

In order to further embody the object of the present invention, the following description is further exemplified on the basis of the first embodiment and the second embodiment of the present invention.
Third embodiment
Fig. 2 is a first Resource mapping schematic diagram of the method for Resource mapping in the embodiment of the present invention, as shown in fig. 2, a frequency domain range of a data channel of a UE1 is a range defined by a PDSCH1 of a Physical Downlink Shared Channel (PDSCH) in the diagram, DCI1 is used for indicating a Resource allocation condition of the data channel of the UE1, where the CORESET1 is a Control Resource Set (CORESET) configured by a base station to the UE 1. Also within the frequency domain of PDSCH1 is a CORESET2, which is not the set of control resources allocated to UE1, but is the set of control resources allocated to other users (e.g., UE2), and is mainly used for transmitting Downlink Control Information (DCI) of other users. The control resource sets CORESET1 and CORESET2 are each 2 OFDM symbols in duration in the time domain. In the embodiment of the invention, CORESET1 can be understood as a first resource region, and CORESET2 can be understood as a second resource region.
The base station specifies that only the control channel or common control channel of UE1 is allowed to be transmitted in the control resource set CORESET1 configured for UE1, and the data channel PDSCH1 of UE1 is transmitted in the remaining resources of the control resource set except for the control channel or common control channel used to transmit UE 1. As shown in fig. 2, on the base station side, PDSCH1 is mapped in the remaining resources except DCI1 in CORESET1 and in the data channel resource region. On the receiving side, the UE1 can determine whether its own dedicated control channel or common control channel exists in the control resource set CORESET1 by blind detection, determine a specific resource location, and receive the data channel PDSCH1 corresponding to the DCI1 at the remaining resource locations in the control channel and in the data channel resource region.
Since the control resource set CORESET2 is a non-configured control resource set for UE1, UE1 is unaware 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 the starting symbol position of PDSCH1 in CORESET2 to UE1 through signaling, the starting symbol of PDSCH1 in CORESET2 in fig. 2 is the 2 nd OFDM symbol, that is, PDSCH1 is resource mapped in CORESET2 from the 2 nd OFDM symbol. On the receive side, the UE1 receives the data channel PDSCH1 according to the CORESET2 resource mapping described above.
Fourth embodiment
Fig. 3 is a schematic view of a second resource mapping of the method for resource mapping in the embodiment of the present invention, as shown in fig. 3, a frequency domain range of a data channel of a UE1 is a range defined by a vertical PDSCH1 in the figure, and a DCI1 is used to indicate a resource allocation situation of the data channel of the UE1, where CORESET1 is a control resource set configured by a base station to a UE 1. DCI for other users is also allowed in CORESET1, for example, DCI2 in fig. 3 is DCI for UE 2. There is also a CORESET2 in the frequency domain of PDSCH1, which is not the set of control resources allocated to UE1, but to other users, e.g., UE3, and is mainly used for transmitting DCI for other users (except UE 1). The control resource sets CORESET1 and CORESET2 are each 2 OFDM symbols in duration in the time domain.
The base station specifies that the control resource set CORESET1 configured for the UE1 allows DCI of other users to be transmitted in addition to DCI of the UE1, but needs to sequentially transmit DCI of a plurality of users in a resource order of first frequency domain and then time domain, from low to high frequency domain, and from front to back time domain. For example, at the base station side in fig. 3, 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, the UE1 obtains the specific resource location of its own control channel DCI1 in the control resource set CORESET1 by blind detection, and considers that the data in the data channel PDSCH1 of the UE1 is mapped on the resources after the DCI1 in CORESET 1.
Since the control resource set CORESET2 is a non-configured control resource set for UE1, UE1 is unaware of CORESET2 and whether it has DCI for other users therein and the specific resource location of the DCI. Therefore, on the base station side, the base station indicates the starting symbol position of PDSCH1 in CORESET2 to UE1 through signaling, as the starting symbol of PDSCH1 in CORESET2 is the 3rd OFDM symbol in fig. 3, that is, PDSCH1 is resource mapped in CORESET2 from the 3rd OFDM symbol. Here, the 3rd OFDM symbol is located outside of CORESET2, i.e., in the data channel resource region, and thus data channel mapping is not performed in CORESET 2. On the receive side, the UE1 receives the data channel PDSCH1 according to the CORESET2 resource mapping described above.
It should be noted that, when there are multiple dedicated control channels of the UE1 in the current scheduling time unit, the ordering order among the multiple dedicated control channels needs to be specified, otherwise, the UE1 cannot determine whether the currently blind-detected DCI is the last DCI in the current scheduling time unit. For example, terminal-specific control channels include: 1) a terminal-specific control channel for scheduling uplink data service 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 the uplink data service in the scheduling time unit after the current scheduling time unit; 4) and the terminal-specific control channel is used for scheduling the uplink data service in the scheduling time unit after the current scheduling time unit. The four terminal-specific control channels are mapped in sequence according to a predefined order. Preferably, the dedicated control channel 2) is finally mapped when the above four control channels exist in the current scheduling time unit.
Fifth embodiment
The network side (or the base station) sets a plurality of resource mapping modes for the specified resource region, and indicates the current used mapping mode to the terminal through signaling. Preferably, the base station indicates the currently used resource mapping mode to the terminal through a physical layer dynamic signaling.
Illustratively, the plurality of resource mapping manners may include: in the first embodiment, one or more of the first resource mapping manner, the second resource mapping manner, the third resource mapping manner, the fourth resource mapping manner, and the fifth resource mapping manner are used.
For example, the plurality of resource mapping manners include a manner one and a manner two. The method comprises the steps of determining DCI corresponding to a terminal and the specific DCI resource position by carrying out blind detection on a control resource set configured to the terminal so as to determine resources for mapping a data channel; mode two determines the mode of resource mapping through the PDSCH starting symbol (i.e. mapping the data channel of the terminal in the remaining resources of the control resource set configured for the terminal, starting from the PDSCH starting symbol, except the DCI of the terminal and the resources occupied by the common control channel). The first method is preferably a resource mapping method two in the first embodiment, and the second method is preferably a resource mapping method three 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 further indicates whether data channel resource mapping should be performed in a mode one or a mode two 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 one of the mapping modes according to the actual situation.
For example, as shown in fig. 3, when no resource overlap occurs between the control resource set CORESET1 configured to the terminal UE1 and the control resource set CORESET2 not configured to the UE1, the base station performs resource mapping on the UE1 data channel PDSCH1 for the CORESET1 in a manner, and indicates to the terminal UE1 through signaling that resource mapping is performed on the CORESET1 configured to the terminal in a first manner, so that the UE1 knows that the data channel PDSCH1 performs resource mapping in the CORESET1 in the first manner, and receives the data channel in the first manner.
Fig. 4 is a third schematic resource mapping diagram of the method for resource mapping in the 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 according to the first method, all DCI must be placed on the overlapping partial resource of the two control resource sets, which greatly restricts the scheduling of the base station, especially when the overlapping partial resource is not too much.
Fig. 5 is a fourth resource mapping schematic diagram of the method for resource mapping in the embodiment of the present invention, as shown in fig. 5, in order to not greatly limit scheduling of the base station, the base station performs resource mapping on CORESET1 in a manner two, and the base station indicates to the terminal UE1 through signaling that resource mapping is performed on CORESET1 in a manner two, so that the UE1 knows that the data channel PDSCH1 performs resource mapping in a manner two, and then receives the data channel in a manner two.
Since the control resource set CORESET2 is a non-configured control resource set for UE1, UE1 is unaware of CORESET2 and whether it has DCI for other users therein and the specific resource location of the DCI. Therefore, on the base station side, the base station indicates the starting symbol position of PDSCH1 in CORESET2 to UE1 through signaling, and as shown in fig. 4 and 5, the starting symbol of PDSCH1 in CORESET2 is the 2 nd OFDM symbol, that is, PDSCH1 performs resource mapping from the 2 nd OFDM symbol in CORESET 2. On the receive side, the UE1 receives the data channel PDSCH1 according to the CORESET2 resource mapping described above.
It should be noted that, when the control resource set CORESET1 configured to the terminal UE1 is in the resource mapping mode two, the base station needs to indicate the starting symbol position (referred to as starting symbol position 1) of the PDSCH1 in the CORESET1 to the UE1 through signaling, and there is also one starting symbol position (referred to as starting symbol position 2) on the control resource set CORESET2 not configured to the UE 1. The two starting symbol positions may be the same or different, where the two starting symbol positions are the same, that is, the UE1 defaults to the starting symbol position of the control resource set CORESET1 being the starting symbol position of the CORESET2, and the base station only needs to uniformly notify information of one starting symbol position through signaling. When the two starting symbol positions are different, the base station needs to respectively notify a plurality of starting symbol positions through signaling, and the plurality of starting symbol positions may respectively correspond to symbols on one subband by taking the subband 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 physical layer signaling.
In practical implementation, a network side may indicate to a terminal whether switching among multiple mapping modes is enabled through a high-level signaling, and when the signaling indicates "not enabled", a base station maps a data channel according to a signaling indication of a starting symbol position of a PDSCH, and the terminal knows that the data channel is mapped from the starting symbol position of the PDSCH indicated by the base station, and receives the data channel from the starting 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 currently used mapping mode to the terminal through physical layer dynamic signaling.
Fig. 6 is a fifth resource mapping diagram of the method for resource mapping in the embodiment of the present invention, as shown in fig. 6, CORESET1 and CORESET2 are two control resource sets configured for UE1, where a duration of CORESET1 in the time domain is 2 symbols, a duration of CORESET2 in the time domain is 3 symbols, and a partial resource overlap exists between CORESET2 and CORESET 1.
In practical implementation, when a control channel or a Common control channel of the UE1 exists in the CORESET2, as shown in fig. 6, there are two control channels of the scheduled user in the CORESET1, namely control channel DCI1 of the UE 1(DCI1 is used for scheduling the data channel PDSCH1 of the UE 1) and control channel DCI2 of other users, and one control channel DCI3 of the scheduled other users and Common control channel DCI in the CORESET 2. Since there are control channels (i.e., control channel DCI1 and Common control channel DCI of UE i) that can be detected blindly by the UE in both of CORESET1 and CORESET2, the UE1 knows the resource situation occupied by CORESET1 and CORESET2, for example, DCI1 in CORESET1 can be received by UE1, Common DCI in CORESET2 can be received by UE1, so that resource mapping can be performed in CORESET1 and CORESET2 in a first manner. Signaling to the UE1 indicates that the resource mapping is done in both CORESET1 and CORESET2 in a way one. Specifically, a predefined mapping order needs to be set for the control channels, the base station sorts the DCIs of all users in a predefined manner in the CORESET1, places the DCIs 2 of other users before the DCI1 of the UE1, and maps the PDSCH1 of the data channel of the UE1 in the remaining resources after the DCI1 except the resources occupied by the CORESET 2; in coerseset 2, the base station orders the DCI of all users in a predefined way, puts the DCI of other users before Common DCI, and maps the data channel PDSCH1 of UE1 in the remaining resources after Common DCI; on the receiving side, after receiving the indication of the resource mapping method of the base station, the UE1 knows that PDSCH1 is mapped in the remaining resources except for 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 method and the indication of other information of DCI 1.
In actual implementation, when there is no control channel and common control channel of the target user in the CORESET2, the base station indicates to the terminal that its data channel is mapped in the first way on resources other than the CORESET2 in the CORESET1, and the data channel is mapped in the second way in other control resource sets (including CORESET 2).
Fig. 7 is a sixth resource mapping diagram of the method for resource mapping in the embodiment of the present invention, as shown in fig. 7, since the CORESET2 does not have the control channel or common control channel of the UE1, it is necessary to map data channels according to the mode two, where the data channels are mapped from the 2 nd symbol on the CORESET2, and the data channels are mapped according to the mode one on the resources except the CORESET2 in the CORESET 1. The base station signals the UE1 to indicate the starting symbol position of resource mapping for the data channel in the CORESET2 as the 2 nd OFDM symbol.
Optionally, the base station may select a suitable data channel mapping manner for a resource region corresponding to a control resource set configured for the target terminal according to different mapping conditions of the CORESET1 and the CORESET2, transmission conditions of the control channels, channel quality environments, and the like, and indicate the mapping manner to the terminal through a 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 a target user exists/is received in the control resource set, or according to the remaining resources except for the aforementioned resources in the control channel or the common control channel of the target user except for other control resource sets (e.g., CORESET2 in fig. 6 and fig. 7) configured for the target user and the remaining resources in the control channel region corresponding to the data channel frequency domain, and so on. The different area divisions should preferably be predefined.
In the embodiment of the invention, the resource mapping of the data channel is carried out in N resource regions respectively according to the resource mapping mode corresponding to each resource region, wherein N is a positive integer. Compared with the prior art, different resource areas map the resources of the data channel according to the corresponding resource mapping mode, so that the data channel can dynamically use the resources of the control channel area, the signaling overhead is reduced, and the resource utilization rate of the control channel area is ensured.
