Description

Method for transmitting enhanced scheduling information, base station and user equipment This application claims to be submitted to the Chinese Patent Office on August 5, 2011, application number 201110223755.4, and the Chinese patent entitled "Method for transmitting enhanced scheduling information, base station and user equipment" Priority of the application, the entire contents of which are incorporated herein by reference. The present invention relates to the field of wireless communication technologies, and in particular, to a method, a base station, and a user equipment for transmitting enhanced scheduling information.

BACKGROUND With the widespread application of data services in wireless networks, the utilization efficiency of spectrum resources is increasingly valued by communication equipment vendors and operators, thereby generating various methods for improving the utilization efficiency of spectrum resources, for example, Single User Multiple Input Multiple Output (SU-MIMO), Multi User Multiple Input Multiple Output (MU-MIMO), high-order modulation, and Heterogeneous Network (Het-Net) technology, which is currently hotly debated. The above methods for improving the utilization efficiency of spectrum resources have been obtained in the 3rd Generation Partnership Project ("3 GPP") Long Term Evolution (LTE) standard. use.

However, in the case where the data channel is greatly enhanced, system performance may be limited by the ability of the control channel. For example, in the 3GPP LTE standard, both uplink and downlink data services can use the MU-MIMO transmission mode, that is, the physical uplink shared channel (Physical Uplink Shared Channel, referred to as "PUSCH") and the physical downlink shared channel (Physical Downlink Shared Channel). , referred to as "PDSCH" for short, can work in MU-MIMO mode to alleviate resource strain when the system is heavily loaded. However, the base station needs to pass the scheduling information through physical The user control device (Physical Downlink Control Channel, referred to as "PDCCH") notifies the scheduled user equipment. If the total available resources of the PDCCH are certain and the control channel information format is constant, there is an upper limit on the number of configurable user equipments. Therefore, although some means for enhancing the efficiency of spectrum resource utilization are used for PDSCH and PUSCH, enhancement methods such as MU-MIMO are at the expense of increasing the resource consumption of the PDCCH. In other words, in the case where the PDCCH resource is limited, the spectrum resource utilization efficiency cannot be improved by using MU-MIMO.

In order to enhance the capacity of the physical downlink control channel, the total available resources of the PDCCH can be expanded by occupying resources of the PDSCH. Correspondingly, the total available resources of the PDSCH are reduced, so that the downlink performance of the system is greatly affected. Other control channels also have resource constraints.

Therefore, how to enhance the performance of the control channel and improve the utilization efficiency of the spectrum resources is a technical problem that needs to be solved at present.

After acquiring the enhanced scheduling information of the user equipment, the base station may send the enhanced scheduling information to the user equipment through a control channel such as a PDCCH. Therefore, on the one hand, the content of the information carried on the control channel is increased, so that the performance of the control channel is enhanced; on the other hand, since the enhanced scheduling information further includes interference information, the user equipment that is interfered in the downlink can use, for example, The advanced receiver technology, such as a non-linear receiver, processes the data transmitted through the data channel according to the enhanced scheduling information, thereby improving the anti-interference capability of the user equipment and improving the utilization efficiency of the spectrum resource.

It should be understood that the term "and/or" in this document, It is just an association that describes the associated object. It means that there can be three kinds of relationships. For example, A and/or B can represent: There are three cases where A exists separately, A and B exist at the same time, and B exists separately. In addition, the character "/" in this article generally indicates that the contextual object is an "or" relationship.

For example, the scheduling information included in the enhanced scheduling information of the user equipment A may be at least one of a modulation mode, resource allocation information, and precoding information of the data channel of the user equipment A.

As shown in FIG. 2A, in the Homo-Net application scenario, cells are geographically mutually In the Het-Net application scenario shown in FIG. 2B, different cells may completely overlap in geographic location. The core of Het-Net is to use cell splitting technology to increase the available spectrum resources, thereby improving the unit geographic area. Throughput, but in the Het-Net application scenario, the uplink and downlink interference in the small interval increases, and the interference situation is more complicated. Specifically, as shown in FIG. 2A, in the Homo-Net application scenario, mainly interference between multiple user equipments in the same cell; and in the Het-Net application scenario, as shown in FIG. 2B, not only the same Interference between multiple user equipments in a cell, and interference between cells.

In the Homo-Net application scenario shown in FIG. 3A, it is assumed that user equipments A and B are paired with two user equipments in MU-MIMO mode, and user equipments A and B are in the same cell, and their physical downlink shared channel resources PDSCH Completely overlapping. User equipments A and B have their own identity information ID_A and ID_B to distinguish between user equipment A and user equipment B in the same cell; user equipments A and B are in the downlink MU-MIMO state, and the base station The same control channel identified as MRNTI is configured for user equipments A and B to enable user equipments A and B to read the included enhanced scheduling information from the control channels shared by both.

User equipments A and B read the control channel identified as MRNTI by detecting the control channel. Through the control channel, user equipment A or B can acquire respective enhanced scheduling information. The control channel identified as the MRNTI includes, for example, scheduling information of the two user equipments of the user equipments A and B. For example, the scheduling information in the PDCCH includes at least:

(1) the modulation mode of the PDSCH of the user equipment A and the modulation mode of the PDSCH of the user equipment B;

(2) resource allocation information of the PDSCH of the user equipment A and resource allocation information of the PDSCH of the user equipment B;

(3) Precoding information of the PDSCH of the user equipment A and/or precoding information of the PDSCH of the user equipment B.

For the user equipment A, the information about the user equipment A is the scheduling information, and the information about the user equipment B is the interference information in the enhanced scheduling information transmitted by the PDCCH; For example, in the enhanced scheduling information transmitted by the PDCCH, the information about the user equipment B is the scheduling information, and the information about the user equipment A is the interference information.

The user equipment can distinguish the scheduling information and the interference information by using specific bits; or the user equipment distinguishes the scheduling information and the interference information by using the respective identification information. The user equipment can use the advanced receiver technology, such as a non-linear receiver, to process the received physical downlink shared channel PDSCH signal according to the scheduling information and the interference information, thereby improving the anti-interference capability of the user equipment and improving the spectrum resource utilization efficiency; Or transmitting data uplink through the PUSCH, such as the physical uplink shared channel, according to the scheduling information and the interference information of the user equipment.

For a given single scheduling information, the transmission time of the PDCCH identified as the MRNTI is set to T1, and the time when the user equipments A and B detect the PDSCH is T2, and the user equipments A and B detect the PDCCH at time T1, and according to the detection. The scheduling information included in the PDCCH that is received is detected at the time T2.

It should be understood that the embodiment of the present invention is only described by taking two user equipments A and B as an example, but the embodiment of the present invention is not limited thereto. For example, if three user equipments A, B, and C are in the same cell and their physical downlink shared channel resources are completely overlapped, user equipment A reads the control channel identified as MRNTI by detecting the control channel. Through the control channel, user equipment A can obtain enhanced scheduling information sent by the base station to the user equipment A. The enhanced information of the user equipment A includes scheduling information and interference information of the user equipment, where the scheduling information of the user equipment includes, for example, a modulation mode, resource allocation information, and precoding information of the data channel of the user equipment A, where the interference information includes, for example, a user. At least one of a modulation scheme, resource allocation information, and precoding information of a data channel of the device B and the user equipment C.

Optionally, as shown in FIG. 3B, for a given single scheduling information, the PDCCH with the identifier MRNTI is set to be transmitted at multiple times, thereby completing the delivery of the scheduling information. Assuming that the transmission timings of the PDCCH are respectively T1 and T2, the user equipments A and B detect the PDSCH at time T3, where T1, Τ2, and Τ3 satisfy: Τ1<Τ2≤Τ3 or Τ2<Τ1≤Τ3, then the PDCCH includes The difference in the transmission time of the scheduling information content can be transmitted by using any of the following transmission methods. Data transmission via the PDCCH:

PDCCH transmission mode 1: The content of the PDCCH at the transmission time T1 is the scheduling information of the user equipment A, and the content included in the transmission time T2 is the scheduling information of the user equipment B;

PDCCH transmission mode 2: The content of the PDCCH at the transmission time T1 and T2 are all part of the scheduling information of the user equipments A and B. Specifically, the content that the PDCCH includes at the transmission time T1 may be part of the scheduling information of the user equipment A and part of the scheduling information of the user equipment B. The content that the PDCCH includes at the transmission time T2 may be the scheduling information of the user equipment A. The rest of the section and the rest of the scheduling information for User Equipment B.

Thus, user equipments A and B can detect the content of the information carried on the PDCCH at times T1 and/or T2 and perform PDSCH detection at time T3.

Therefore, the method for transmitting enhanced scheduling information in the embodiment of the present invention can transmit the enhanced scheduling information including the interference information to the interfered user equipment by using the control channel at different times, thereby not only increasing the content of the information carried on the control channel, but also The transmission mode of the control channel transmission data can be enhanced, and the performance of the control channel can be comprehensively improved, thereby improving the anti-interference capability of the user equipment, improving the utilization efficiency of the spectrum resources, and improving the overall performance of the system.

Through the physical downlink control channel, the user equipment A can obtain the scheduling information about the user equipment A. In addition, the user equipment A can also obtain the information of the interference signal scheduled in the transmission resource of the user equipment A. The interference information may include, for example, a transmission resource of an interference signal, a modulation mode of the interference signal, and the like. In the 3GPP LTE standard, a transmission resource of the interference signal is a physical resource block (PRB) allocated by the interference signal, and, in addition, an interference signal Each part of the transmission resource corresponds to the corresponding modulation method.

For user equipment A, in the enhanced scheduling information transmitted through the PDCCH, The information of the user equipment A is the scheduling information, and the information about the interference signal is the interference information. The user equipment may process the received physical downlink shared channel PDSCH signal by using advanced receiver technologies such as a non-linear receiver according to scheduling information and interference information.

For a given single scheduling information, it is assumed that the transmission time of the PDCCH identified as CRNTI-A is T1, and the time when the user equipment A detects the PDSCH is T2, then the user equipment A detects the PDCCH at time T1, and according to the detected PDCCH. The included scheduling information and interference information are detected at the time T2.

Optionally, as shown in FIG. 3D, for a given single scheduling information, it is assumed that the PDCCH identified as CRNTI is transmitted at multiple times, thereby completing the delivery of the scheduling information. Assuming that the transmission time of the PDCCH is T1 and Τ2, respectively, the user equipment detects the PDSCH at time Τ3, where T1, Τ2, Τ3 satisfy: Τ1<Τ2≤Τ3 or Τ2<Τ1≤Τ3, then the scheduling information included in the PDCCH is calculated. The difference in the transmission time of the content, the data can be transmitted through the PDCCH using any of the following transmission methods:

PDCCH transmission mode 1: The content of the PDCCH at the transmission time T1 is the scheduling information of the user equipment A, and the content included in the transmission time T2 is the scheduling information of the interference signal;

PDCCH transmission mode 2: The content of the PDCCH at the transmission time T1 and T2 are both part of the scheduling information of the user equipment A and part of the interference information. Specifically, the content included in the PDCCH at the transmission time T1 may be part of the scheduling information of the user equipment A and part of the interference information; the content included in the PDCCH at the transmission time T2 may be the rest of the scheduling information of the user equipment A and Interfere with the rest of the information.

Therefore, the user equipment A can detect the content of the information carried on the PDCCH at time T1 and/or T2, and perform the detection of the PDSCH at time T3.

In the Homo-Net application scenario as shown in FIG. 3E, user equipments A and B have their own identity information ID_A and ID_B to achieve differentiation between user equipment A and user equipment B in the same cell. User equipments A and B are in an uplink MU-MIMO state, and the base station configures a shared control channel of the same identifier MRNTI for user equipment A and user equipment B. The user equipments A and B detect the physical downlink control channel, and read the control channel identified as the MRNTI. The control channel identified as the MRNTI includes scheduling information of the two user equipments of the user equipments A and B. The user equipment can distinguish the respective scheduling information by specific bit differentiation or respective identification information.

For a given single scheduling information, it is assumed that the PDCCH identified as the MRNTI is transmitted at multiple times to complete the delivery of the scheduling information. 4, the transmission time of the PDCCH is T1, Τ2, respectively, and the user equipment can transmit data uplink through the data channel such as PUSCH at time Τ3, where Tl, Τ2, Τ3 satisfy: Τ1<Τ2<Τ3 or Τ2<ΤΚΤ3, then According to the difference in transmission time of the scheduling information content included in the PDCCH, data transmission may be performed through the PDCCH by using any of the following transmission methods:

The user equipments A and B are in the uplink MU-MIMO state, and the base station configures the physical downlink control channel identified as CRNTI-A for the user equipment A, and the base station configures the physical downlink control channel identified as CRNTI-B for the user equipment B. The user equipments A and B respectively detect the physical downlink control channels, and respectively read the control channels identified as CRNTI-A and CRNTI-B. The two control channels include the uplink scheduling information of the user equipments A and B, respectively. The information is extended to ensure space division multiplexing of the respective PUSCH channels of the user equipment A and the user equipment B on the uplink physical channel resources.

The two control channels include the downlink scheduling information of the user equipments A and B respectively. The information is extended to ensure space division multiplexing of the respective PDSCH channels of the user equipment A and the user equipment B on the downlink physical channel resources.

For a given single scheduling information, it is assumed that the PDCCH identified as CRNTI-A and the PDCCH identified as CRNTI-B are transmitted at different single moments to complete the delivery of the scheduling information. The transmission time of the PDCCH identified as CRNTI-A is T1, and the transmission time of the PDCCH identified as CRNTI-B is T2, and user equipment A and user equipment B detect PDSCH at time T3, where T1, Τ2, Τ3 satisfy: ΤΚΤ2 <Τ3 or Τ2<Τ1<Τ3, then the standard i is only The delay information included in the control channel of the CRNTI-A indicates that the detection time of the PDSCH by the user equipment A is T3, and the delay information included in the control channel identified as CRNTI-B indicates that the detection time of the PDSCH by the user equipment B is T3. .
