Description

Resource indication method, PUCCH transmission method, and network side device

Cross-reference to related applications

The present application is based on a Chinese patent application filed on Jan. 23, 2017, the filing date of which is hereby incorporated by reference.

Technical field

The present application relates to the field of communications, and in particular, to a resource indication method, a PUCCH transmission method, a network side device, and a storage medium.

Background technique

In order to improve the stability of the Physical Uplink Control Channel (PUCCH), the 3rd Generation Partnership Project (3GPP) Rel10 for User Equipment (User Equipment, UE for short) The uplink multi-antenna technology introduces the Space Orthogonal-Resource Transmit Diversity (SORTD) technology.

When the UE supports multi-antenna transmission, if the transmission of the PUCCH can make full use of the multi-antenna and the corresponding antenna power amplifier, the power resources can be fully utilized and the maximum diversity gain can be realized. In order to achieve additional diversity, in Rel-10, a 2-antenna SORTD of PUCCH is introduced. This mechanism is also backward compatible with the Rel-8 PUCCH design.

The basic idea of SORTD is to use different orthogonal resources (ie different PUCCH resources: RB, cyclic shift or orthogonal sequence) on different antenna ports to transmit the same uplink control information of the same UE (Uplink Control Information, referred to as For UCI).

It should be noted that uplink PUCCH transmission is the most important control information in Long-Term Evolution (LTE) and Long-Term Evolution Advance (LTE-A), according to 3GPP. In the latest specification of Rel13.3, PUCCH introduces SORTD technology to improve the reliability of PUCCH under multiple antennas. However, unlike other channel diversity technologies, other channels such as Physical Uplink Shared Channel (PUSCH) and Physical Downlink Shared Channel (PDSCH) are not affected by channel resources. The situation improves stability. However, PUCCH sacrifices valuable PUCCH orthogonal code resources. That is to say, if a cell can carry 100 UEs before the introduction of the SORTD technology. If all UEs in the entire cell have SORTD technology enabled. It can only carry 50 UEs. The impact on the capacity of the cell is large. Moreover, the multi-antenna SORTD technology of PUCCH can only achieve better results when the antenna channel is not correlated. When the antenna channel is related, or the channel quality is good, the role of the SORTD is minimal.

That is to say, if the PUCCH is transmitted by the SORTD technology, a second set of resources in the 2 antennas needs to be redistributed to implement SORTD. That is to say, the consumption of resources is twice as long as the early consumption, resulting in high resource consumption and low resource utilization.

In view of the above problems, an effective solution has not been proposed in the related art.

detailed description

The present application will be described in detail below with reference to the drawings in conjunction with the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict.

It should be noted that the terms "first", "second" and the like in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or order.

Currently, SORTD technology is only applied to PUCCH. Compared with the Non-SORTD transmission mechanism, SORTD needs to use twice the PUCCH resources. As shown in FIG. 1, the number of UEs that the corresponding cell can carry is also reduced. For a UE with 4 physical antennas, a specific implementation of antenna virtualization is used. Essentially, a transparent mechanism is used to map the signals of the 2 antenna ports to the 4 physical antennas.

How to determine different PUCCHs used by different antenna ports (antenna port Antenna port 0, ie, P0 and antenna port Antenna port 1, ie, P1) in the SORTD for different PUCCH formats (ie, PUCCH format, or PUCCH application scenario) Resources. In fact, it is necessary to reserve the PUCCH resource on P1 in the Radio Resource Control (RRC) message. The following describes each situation:

(1) For PUCCH format 1, ie SR resources:

The evolved node eNodeB (also referred to as a base station) configures the PUCCH 1 resources used by the antenna ports P0 and P1, respectively, through the following fields in the RRC message: sr-PUCCH-ResourceIndex and sr-PUCCH-ResourceIndexP1-r10. (See SchedulingRequestConfig of 36.331)

(2) For PUCCH format 1a/1b, that is, Acknowledgement/Non-Acknowledgement (abbreviated as ACK/NACK) resources (non-carrier aggregation scenario):

For the Frequency Division Duplex (FDD), the two PUCCH 1 resources used by the antenna ports P0 and P1 are respectively allocated through the network (see Section 10.1.2.1 of 36.213). For the scenario of TDD and Hybrid Automatic Repeat Request (HARQ) bundling, the two PUCCH 1 resources used by antenna ports P0 and P1 are obtained by n _CCE and n _CCE +1, respectively. (See section 10.1.3.1 of 36.213)

(3) For PUCCH format 2/2a/2b, that is, Channel State Information (CSI) resources:

For periodic CSI reporting, the eNodeB configures the PUCCH 2 resources used by the antenna ports P0 and P1, respectively, through the following fields in the RRC message: cqi-PUCCH-ResourceIndex-r10 and cqi-PUCCH-ResourceIndexP1-r10. Aperiodic CSI reporting uses PUSCH transmission, so SORTD is not supported.

(4) For PUCCH format 1b with channel selection:

In Rel-10, PUCCH format 1b with channel selection does not support transmission diversity, ie does not support SORTD.

(5) For PUCCH format 3:

For the scenario in which the PUCCH format 3 is used, the TPC command for PUCCH field in the downlink DCI (except the first downlink DCI sent on the primary cell (PCell)) will indicate that 1 is selected from the 4 PUCCH 3 resources. (one pair for 2 antenna transmission) is used to reply ACK/NACK. The 4 PUCCH 3 resources are configured by n3 PUCCH-AN-List-r10 of format3-r10; for 2 antenna transmission, 4 PUCCH 1 resources of the second antenna port are configured by n3 PUCCH-AN-ListP1-r10. (See sections 10.1.2.2.2 and 10.1.3.2.2 of 36.213)

(6) For Semi-Persistent Scheduling (SPS):

For downlink transmission, if the received downlink DCI indicates Downlink (DL) SPS activation, the TPC command for PUCCH field in the DCI will indicate that one of the four PUCCH 1 resources is selected (2 antenna transmission) Is a pair) used to reply ACK/NACK. The four PUCCH 1 resources are configured by the n1 PUCCH-AN-PersistentList of the SPS-ConfigDL; for the 2-antenna transmission, the four PUCCH 1 resources of the second antenna port are configured by n1 PUCCH-AN-PersistentListP1-r10. (See section 9.2 of 36.213)

(7) For ACK/NACK Repetition:

If the UE is configured with ACK/NACK Repetition (called HARQ-ACK Repetition in the protocol), the eNodeB configures the antenna port through the following fields in the RRC message: n1PUCCH-AN-Rep and n1PUCCH-AN-RepP1-r10. PUCCH 1 resources used by P0 and P1 (see ackNackRepetition of 36.331).

After determining the PUCCH resources used by the two antenna ports and the PUCCH information to be transmitted, the rest is the processing of the transmission diversity.

If the transmit antenna is irrelevant, SORTD can provide the best diversity performance, but consumes more orthogonal resources (Rel-8/Rel-9 uses only 1 resource, while Rel-10 may use 2) Resources), which may reduce the capacity of the PUCCH.

As shown in FIG. 2, for a conventional 3GPP scheme, for a UE supporting SORTD, a pair of PUCCH resources, that is, PUCCH Resource-P0 (ie, Antenna port 0 resource) and PUCCH Resource-P1 (ie, Antenna port 1 resource), and this allocation process is based on RRC quasi-static allocation. Even when the channel quality is changed, the SORTD is no longer necessary or does not help to improve the reliability (for example, the channel of the two antennas is strongly correlated), the resources of this P1 antenna port cannot be released. So it was wasted.

FIG. 3 is an implementation manner of the solution proposed in the present application. As shown in FIG. 3, the network side may share a P1 resource to multiple UEs, and the network side controls the quality of the uplink channel at any time. In the case, the UE that really needs this P1 resource is allowed to start the SORTD dual antenna transmission, and other UEs that do not need to start the SORTD can only use the P0 port for single antenna transmission. It can be seen that this new PUCCH Resource-P1 allocation method is adopted. The total number of PUCCH resources occupied by the same number of UEs is reduced. In other words, the same number of resources can be used to carry more UEs without affecting transmission stability. The present application is described below in conjunction with the embodiments:

Embodiment 1:

In this embodiment, a resource indication method is provided. FIG. 4 is a flowchart of a resource indication method according to an embodiment of the present application. As shown in FIG. 4, the process includes the following steps:

Step S402, allocating resources for two or more user equipment UEs in the access network;

Step S404, the resource allocated to the UE is indicated to the UE, where the resource is used by the UE to send a physical uplink control channel PUCCH, and at least two UEs of the two or more UEs use the spatial orthogonal resource transmission diversity SORTD to transmit the PUCCH. Share the same antenna port Antenna port 1 resource.

The resource indication method may be performed by the network side device. In an implementation manner of the application, the foregoing method may be performed by the eNodeB. In the above embodiment, the same antenna port Antenna port 1 resource shared by the UE substantially shares the PUCCH resource in the same antenna port Antenna port 1 (that is, the resource dedicated to transmitting the PUCCH in the Antenna port 1). In the following embodiments of the present application, the Antenna port 1 resource substantially refers to the PUCCH resource in the Antenna port 1. The two or more UEs mentioned above are two UEs.

With the above-mentioned embodiments, since at least two UEs in the access network share one antenna port Antenna port 1 resource, it is not necessary to separately configure one Antenna port 1 resource for each UE, thereby solving the resources existing in the related art. The problem of high consumption and low resource utilization, thereby reducing the resource consumption and improving the resource utilization. In an optional embodiment, the indicating the resource allocated to the UE to the UE includes: sending a first indication message to the UE, where the first indication message is used to indicate an Antenna port 1 resource shared by the UE and other UEs; Sending a second indication message to the UE, where the second indication message is used to indicate whether the UE uses the Antenna port 1 resource shared with other UEs.

In an embodiment of the present application, the first indication message includes a radio resource control RRC message.

In an embodiment of the present application, the second indication message includes one of the following: a downlink control message DCI 1, DCI 1A, DCI 2, DCI 2A, DCI3, and DCI3A.

In an embodiment of an implementation manner of the present application, allocating the foregoing resources to accessing two or more UEs in the foregoing network includes: determining a UE that needs to allocate an Antenna port 1 resource among two or more UEs; and configuring an Antenna port 1 resource in need The UEs that need to perform resource sharing are determined, and the UEs that do not need to perform resource sharing are grouped; the UEs that need to perform resource sharing are grouped, wherein the number of UEs in each group is two or more; An Antenna port 1 resource and an Antenna port 1 resource for each UE that does not need to share resources. In this embodiment, the UEs accessing the foregoing network may be classified into three types, the first type of UEs only use the Antenna port 0 resource to send PUCCH, and the second type of UEs and the third type of UEs use Antenna port 0 resources and Antenna port 1 The resource sends a PUCCH, where the second type of UE is a UE that needs to share the Antenna port 1 resource with other UEs, and the third type of UE is a UE that is configured with the Antenna port 1 resource separately, that is, the Antenna port 1 resource is not shared with other UEs. In this embodiment, when determining the UE that needs to allocate the Antenna port 1 resource, it is determined according to the quality of the uplink channel, that is, the UE that determines that the quality of the uplink channel is lower than a predetermined threshold is required to allocate the Antenna port 1 resource. UE.

In an embodiment of an implementation manner of the present application, the grouping of the UEs that need to perform resource sharing includes: determining, by using the following formula, a maximum number of groups to be divided into P: P=TM-2N, where T is a network to be configured The number of assigned Antenna port 1 resources, M is the number of UEs that need to share resources, N is the number of UEs that do not need to share resources, T is an integer greater than 0, and M is an integer greater than or equal to 2, where N is An integer greater than or equal to 0; the UEs that need to share resources are divided into Q groups, where Q is a positive integer and Q≤P. In this embodiment, N may take 0, that is, there may be a case where there is no UE that separately occupies the Antenna port 1 resource. In addition, when the UEs that need to share resources are divided into Q groups, the number of UEs in different groups may be different. The UEs that need to share resources may be divided into Q groups according to the uplink channel quality of the UE, and the quality of the uplink channel is better. The more the UE can share the Antenna port 1 resources with other UEs, the UE with poor uplink channel quality can only share the Antenna port 1 resources by itself, or share the Antenna port 1 resources with one UE (or two UEs).

It can be seen from the foregoing embodiment that after the network determines the current load and bears the UE, the current UEs can be grouped. The resources of the PUCCH antenna port P1 of the UE having at least one of the at least one packet are the same. In the above embodiment, when the allocated resource needs to be indicated by the indication information, the specific implementation may be implemented as follows:

Placing a specific flag bit to a specific downlink message (corresponding to the first indication message described above) and informing the UE of the resource configuration situation through the downlink message, letting the UE know that the P1 PUCCH resource is shared with other UEs (corresponding to the above Antenna port 1 resource). The network side can also store this grouping situation. For the UEs in the packet, the network receives channel quality information sent by the UE, and performs uplink channel quality evaluation by measuring an uplink reference signal or the like. For a UE that performs SORTD most suitable for the uplink channel quality (eg, the uplink channel quality is poor, and the antenna is not strongly correlated), a specific UE is set in a specific DCI downlink message (corresponding to the second indication message described above). The Bit bit is 1 to inform the UE that the P1 resource can be used for uplink SORTD transmission. For other co-group UEs that are not selected, the UE is notified that the P1 resource cannot be used by setting a specific Bit bit in the specific DCI downlink message to 0. Of course, setting the above bit to 1 or setting it to 0 is only a preferred embodiment. In a specific application, the indication may also be performed by other setting methods.

In an embodiment of an implementation manner of the present application, after the resource allocated to the UE is indicated to the UE, the method further includes: determining that a new UE accesses the network, and/or having access to the foregoing The UE of the network disconnects from the network; re-allocates resources for the UEs in the current network, and gives an indication. That is to say, when the number of UEs in the access network changes, resources need to be allocated to UEs in the access network.

The method embodiment provided by the second embodiment of the present application can be executed in a mobile terminal, a computer terminal or the like. For example, the mobile terminal is operated on a mobile terminal. FIG. 5 is a hardware structural block diagram of a mobile terminal for transmitting a PUCCH according to an embodiment of the present application. As shown in FIG. 5, mobile terminal 50 may include one or more (only one of which is shown in FIG. 5) processor 502 (processor 502 may include, but is not limited to, a processing device such as a microprocessor MCU or a programmable logic device FPGA. A memory 504 for storing data, and a transmission device 506 for communication functions. It will be understood by those skilled in the art that the structure shown in FIG. 5 is merely illustrative, and does not limit the structure of the above electronic device. For example, mobile terminal 50 may also include more or fewer components than shown in FIG. 5, or have a different configuration than that shown in FIG.

The memory 504 can be used to store software programs and modules of application software, such as program instructions/modules corresponding to the PUCCH transmission method in the embodiment of the present application, and the processor 502 executes each by running a software program and a module stored in the memory 504. A functional application and data processing, that is, the above method is implemented. Memory 504 can include high speed random access memory and can also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid state memory. In some examples, memory 504 can further include memory remotely located relative to processor 502, which can be connected to mobile terminal 50 over a network. Examples of such networks include, but are not limited to, the Internet, intranets, local area networks, mobile communication networks, and combinations thereof.

Transmission device 506 is for receiving or transmitting data via a network. The above-described network specific example may include a wireless network provided by a communication provider of the mobile terminal 50. In one example, the transmission device 506 includes a Network Interface Controller (NIC) that can be connected to other network devices through a base station to communicate with the Internet. In one example, the transmission device 506 can be a Radio Frequency (RF) module for communicating with the Internet wirelessly.

A method for transmitting a PUCCH is also provided in this embodiment. FIG. 6 is a flowchart of a method for transmitting a PUCCH according to an embodiment of the present application. As shown in FIG. 6, the process includes the following steps:

Step S602, determining resources allocated by the network;

Step S604: The physical uplink control channel (PUCCH) is sent by using the foregoing resource. The at least two user equipments (UEs) accessing the network share the same antenna port Antenna port 1 resource when transmitting the PUCCH by using the spatial orthogonal resource transmission diversity SORTD.

The above method can be applied to the terminal shown in FIG. 5, that is, the execution body of the above operation may be a terminal.

With the above-mentioned embodiments, since at least two UEs in the access network share one antenna port Antenna port 1 resource, it is not necessary to separately configure one Antenna port 1 resource for each UE, thereby solving the resources existing in the related art. The problem of high consumption and low resource utilization, thereby reducing the resource consumption and improving the resource utilization.

In an optional embodiment, determining the resource allocated by the network includes: receiving a first indication message sent by the network; determining an Antenna port 1 resource shared with the predetermined UE according to the first indication message; receiving a second indication sent by the network a message, where the second indication message is used to indicate whether to use an Antenna port 1 resource shared with the predetermined UE, and determine the resource according to the second indication message.

In an implementation manner of the present application, determining, according to the foregoing second indication message, that the resource is: when the second indication message is used to indicate that the Antenna port 1 resource shared with the predetermined UE is used, determining that the resource is a pre-allocated Antenna port 0 resource and The Antenna port 1 resource shared with the predetermined UE; when the second indication message is used to indicate that the Antenna port 1 resource shared with the predetermined UE cannot be used, the resource is determined to be a pre-allocated Antenna port 0 resource.

The foregoing predetermined UE corresponds to the other UEs, that is, other UEs that are in the same group as the terminal that receives the first indication message.

In the above embodiment, the terminal receives the PUCCH Resource-P0 and P1 resources (ie, Antenna port 0 and Antenna port 1 resources) of the network configuration, and stores them. When the terminal receives a specific message (corresponding to the first indication message described above) sent from the network side, it indicates that it has shared a certain PUCCH Resource-P1 resource with other UEs. Then, a specific bit bit is determined from a specific downlink DCI message (corresponding to the second indication message described above). When the specific bit position is 1, it indicates that the P1 corresponding resource is acquired by itself. The next PUCCH transmission uses the previously stored PUCCH Resource-P0 and P1 resources, and is transmitted using the SORTD dual antenna. When the specific bit position is 0, the next PUCCH can only use PUCCH Resource-P0 for single antenna transmission. Of course, setting the above bit to 1 or setting it to 0 is only a preferred embodiment. In a specific application, the indication may also be performed by other setting methods.

Embodiment 3

In this embodiment, the technical details in the present application are mainly described. In this embodiment, PUCCH Resource-P1 (or simply P1) is equivalent to the above-mentioned Antenna port 1:

As shown in Table 1-4, different resource allocation examples can be obtained by using different multiplexing coefficients for PUCCH Resource-P1. The resource reuse factor is defined as:

S=[R_no_shared/R_shared]

Where S represents the multiplexing coefficient, and R_no_shared represents the number of P1 resources required when there is no sharing between UEs in the conventional 3GPP scheme, and R_shared represents the number of P1 resources required for sharing by the patent method. [] represents an integer, optionally rounded up, rounded up or rounded down. Here is an example of rounding.

Table 4 shows the resource occupation when there is no multiplexing. As shown in the attached table 4, 11 UEs are taken as an example, and R_no_shared=11. When multiplexed in the manner of the attached table 1, R_shared=6 at this time M= [11/6]=2, the multiplexing factor is 2 at this time, which means that half of the resources are saved compared to the prior art. For Schedule 2, M = [11/4] = 3, at which point the reuse factor is 3, which means that two-thirds of the resources are saved relative to the prior art.

For the third table, only another example of a hybrid allocation method is proposed, that is, the network side may also choose to enable shared resources for some UEs, and some UEs do not use shared resources. The amount of resources saved at this time may be within half.

Schedule 1 (subject reuse factor is 2)

Schedule 2 (subject reuse factor is 3)

Schedule 3 (mixing of various reuse factors, there are 2 with 3)

Schedule 4 (no multiplexing scheme, ie 3GPP existing methods)

In this embodiment, the network side determines how the packet is shared, and what is the approximate multiplexing coefficient S.

It is assumed that in the scenario where there are currently 6 PUCCH resources available on the network side, 4 UEs supporting the SORTD access the network cell. The following describes the situation:

Since only 6 PUCCH resources are left at present, if 4 UEs are enabled with the traditional mode 3GPP SORTD, the required number of resources is 4×2=8, and the number of P1 resources is 4. Of the six resources currently remaining, four of them are P0 resources that must be allocated to four UEs. Therefore, only 6-4=2 resources can be allocated to P1. Then the multiplexing coefficient M=4/2=2. That is, two UEs need to share one P1 resource.

For the UEs that have determined that the P1 resources are to be shared, the corresponding UE may be first notified by the corresponding downlink RRC message, and the P1 resources allocated to the corresponding UE are shared with other UEs, and whether the shared P1 resource can be used. It is also necessary to monitor from DCI whether another condition is met. The following key messages are sent to UE1 to UE4. Examples of key parts in the RRC message are as follows:

PUCCH-ConfigDedicated::=SEQUENCE{

SharedPUCCH-P1-Enabled=1Enumerated{0,1}

}

The message names and formats for the two examples are given in Schedule 5.

Schedule 5

The sharing mechanism proposed in the embodiment of the present application is enabled by setting the SharedPUCCH-P1-Enabled to 1. At this time, the UE needs to monitor another bit in the DCI, for example, the name is PUCCHResource-P1-Transmit. When the bit is found to be 1, the uplink transmission of the UE adopts dual antenna SORTD transmission, otherwise, the single antenna transmission mode is adopted. An example of a new field format for terminal monitoring DCI is as follows, where there is only one UE in each group. This field is set to 1. E.g:

DCI 1A/1/0/2A/2 and so on:

UE1: PUCCHResource-P1-Transmit=1

UE2: PUCCHResource-P1-Transmit=0

UE3: PUCCHResource-P1-Transmit=1

UE4: PUCCHResource-P1-Transmit=0

In order to grasp the dynamic channel change of each UE, the network side periodically periodically feeds back channel information (including but not limited to a Rank Indicator (RI), a Channel Quality Indicator (CQI), etc.). Processing is performed and combined with measurements of uplink channel specific reference signals (including but not limited to SRS, PUCCH DMRS) to determine how to determine which UE in each group most needs this P1 resource. For example, when the uplink measurement to the channel of a certain UE is the worst, the dual antenna transmission resource allocated to the UE SORTD. This periodic measurement and decision ensures the adaptability and timeliness of the method.

When a new UE joins, the network re-evaluates the reuse conditions and rearranges the resource allocation table. Restart the aforementioned key processes. It is ensured that the method in the embodiment of the present application can also be adaptively changed when the number of UEs is changed.

FIG. 7 is a flow chart of interaction between a network and a terminal according to an embodiment of the present application. As shown in FIG. 7, the interaction between the network and the terminal is implemented by the following steps:

S702. The UE initiates a registration request.

S704. The network determines a general multiplexing coefficient of the PUCCH Resource-P1 according to the number of UEs currently served, the load, and the like.

S706: Generate and store a PUCCH Resource-P0 and a PUCCH Resource-P1 allocation table according to the multiplexing coefficient, and send a downlink message to notify the UE according to the resource allocation in the allocation table, and specify a UE occupation for the UE sharing the PUCCH Resource-P1. P1 resources (see the two tables above in Figure 7 for details);

S708, UE1, UE3 use the network indication, using the resources allocated by P0 and P1, the uplink dual antenna transmits the PUCCH, and the uplink of the UE2 and the UE4 adopts the allocated P0 resource, and the single antenna transmits the PUCCH;

S710: Each UE periodically sends an uplink reference signal SRS, etc., and the auxiliary network measures an uplink channel of each UE.

S712. Demodulate and measure the uplink channel of each UE, and find the UE with the worst uplink channel from each packet according to the information of the PUCCH and the result of measuring the SRS, and allocate the PUCCH to improve the reliability by using the dual antenna, for example, at this time. Measurement, UE2 and UE4 have the worst quality;

S714, indicating a new allocation in the downlink DCI;

S716, UE2, and UE4 use the network indication, and use the resources allocated by P0 and P1 to transmit the PUCCH in the uplink dual antenna. The uplink of the UE1 and the UE3 adopts the allocated P0 resource, and the single antenna transmits the PUCCH (as shown in the lowermost table in FIG. 7). Show);

S718, adding a batch of UEs, for example, UE5, UE6;

S720: The network determines the PUCCH Resource-P1 approximate multiplexing system for the new UE according to the number of UEs currently served, the load, and the like, and repeatedly performs the foregoing interaction steps.
