Description

Resource indication method, PUCCH (physical uplink control channel) sending method and network equipment

Technical Field

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

Background

In order to improve the stable transmission of the physical uplink control channel (Physical Uplink Control Channel, abbreviated PUCCH), the Spatial Orthogonal Resource Transmission Diversity (SORTD) technology is introduced in the third generation mobile communication partner project (3 rd Generation partnership project, abbreviated 3 GPP) Rel10 for the User Equipment (UE) uplink multi-antenna technology.

When the UE supports multi-antenna transmission, if the transmission of the PUCCH can fully utilize the multi-antennas and corresponding antenna power amplifiers, it is possible to fully utilize power resources and achieve maximum diversity gain. In Rel-10, 2-antenna SORTD of PUCCH was introduced in order to achieve additional diversity. This mechanism is simultaneously backward compatible with the PUCCH design of Rel-8.

The basic idea of SORTD is to transmit the same uplink control information (Uplink Control Information, abbreviated UCI) of the same UE on different antenna ports using different orthogonal resources (i.e. different PUCCH resources: RBs, cyclic shifts, or different orthogonal sequences).

It should be noted that, in Long-Term Evolution (Long-Term Evolution, abbreviated as LTE) and Long-Term Evolution-advanced (Long-Term Evolution Advance, abbreviated as LTE-a), uplink PUCCH transmission is the most important control information, and according to the latest specifications of 3gpp rel13.3, PUCCH introduces SORTD technology to improve the reliability of PUCCH under multiple antennas. However, unlike the diversity technique of other channels, the transmission diversity of other channels, such as a physical uplink shared channel (Physical Uplink Shared Channel, abbreviated PUSCH), a physical downlink shared channel (Physical Downlink Shared Channel, abbreviated PDSCH), and the like, improves stability without affecting channel resources. But PUCCH sacrifices precious PUCCH orthogonal code resources. That is, if one cell can carry 100 UEs before SORTD technology is not introduced. If SORTD technology is enabled for all UEs of the entire cell. Only 50 UEs can be carried. The capacity impact on the cell is large. And the multi-antenna SORTD technology of the PUCCH can only play a good role if the antenna channels are uncorrelated. SORTD plays very little role in the case of antenna channel correlation, or better channel quality itself.

That is, if the SORTD technique is used to transmit PUCCH, a set of resources needs to be allocated to the second antenna port of the 2 antennas to implement SORTD. That is, the occupation consumption of the resources is 2 times of the early stage, so that the occupation consumption of the resources is high and the utilization rate of the resources is low.

In view of the above problems, no effective solution has been proposed in the related art.

Detailed Description

The invention will be described in detail hereinafter with reference to the drawings in conjunction with embodiments. It should be noted that, in the case of no conflict, the embodiments and features in the embodiments may be combined with each other.

It should be noted that the terms "first," "second," and the like in the description and the claims of the present invention and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order.

Currently, SORTD technology is only applied to PUCCH. And SORTD needs to use 2 times PUCCH resources compared to Non-SORTD transmission mechanisms. 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, antenna virtualization for a particular implementation would be used. Essentially, a transparent mechanism is used to map signals from the 2 antenna ports to the 4 physical antennas.

How to determine different PUCCH resources used by different Antenna ports (Antenna port 0, i.e., P0 and Antenna port 1, i.e., P1) in SORTD for different PUCCH formats (i.e., PUCCH formats, or PUCCH application scenarios). It is the case that PUCCH resources on P1 are reserved in a radio resource control (Radio Resource Control, abbreviated RRC) message. The following describes various cases:

(1) For PUCCH format 1, i.e. SR resource:

the evolved node eNodeB (also referred to as a base station) passes the following fields in the RRC message: sr-PUCCH-ResourceIndex and sr-PUCCH-ResourceIndex P1-r10 configure PUCCH 1 resources for use by antenna ports P0 and P1, respectively. (see: 36.331 SchedulingRequestConfig)

(2) For PUCCH format 1a/1b, i.e., acknowledgement/Non-Acknowledgement (ACK/NACK) resources (Non-carrier aggregation scenario):

for the frequency division duplex mode (Frequency Division Duplex, abbreviated as FDD), the 2 PUCCH 1 resources used by the antenna ports P0 and P1 are respectively obtained by network allocation (see section 10.1.2.1 of 36.213). For the scenario of TDD and using hybrid automatic repeat request (Hybrid Automatic Repeat Request, abbreviated HARQ) bundling, the 2 PUCCH 1 resources used by antenna ports P0 and P1 are respectively transmitted through n _CCE And n _CCE +1. (see section 10.1.3.1 of 36.213)

(3) For PUCCH format 2/2a/2b, i.e. channel state information (Channel State Information, abbreviated CSI) resources:

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

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

in Rel-10, PUCCH format 1b with channel selection does not support transmit diversity, i.e., SORTD is not supported.

(5) For PUCCH format 3:

for the scenario using PUCCH format3, the TPC command for PUCCH field in the downlink DCI (except the first downlink DCI transmitted on the Primary Cell (PCell)) will indicate that 1 out of 4 PUCCH 3 resources (a pair at 2 antenna transmission) is selected for the reply ACK/NACK. The 4 PUCCH 3 resources are configured through n3PUCCH-AN-List-r10 of formats 3-r 10; for 2-antenna transmission, the 4 PUCCH 1 resources of the second antenna port are configured through n3PUCCH-AN-ListP1-r 10. (see sections 10.1.2.2.2 and 10.1.3.2.2 of 36.213)

(6) For Semi-permanent scheduling (Semi-Persistent Scheduling, abbreviated SPS):

for Downlink transmission, if the received Downlink DCI indicates Downlink (DL) SPS activation, a TPC command for PUCCH field in the DCI will indicate 1 out of 4 PUCCH 1 resources (a pair at 2 antenna transmission) to choose for replying to an ACK/NACK. The 4 PUCCH 1 resources are configured by n1 PUCCH-AN-persistence of SPS-ConfigDL; for 2-antenna transmission, the 4 PUCCH 1 resources of the second antenna port are configured by n1 PUCCH-AN-PersistentistP 1-r 10. (see section 9.2 of 36.213)

(7) For ACK/NACK Repetition:

if the UE configures ACK/NACK Repetition (referred to as HARQ-ACK Repetition in the protocol), the eNodeB will pass through the following fields in the RRC message: n1PUCCH-AN-Rep and n1PUCCH-AN-RepP1-r10 configure PUCCH 1 resources used by antenna ports P0 and P1, respectively (see ackNackRepetition of 36.331).

After determining the PUCCH resources used by the 2 antenna ports and the PUCCH information to be transmitted, the rest is the processing of the transmit diversity.

SORTD may provide the best diversity performance if the transmit antennas are uncorrelated, but may consume more orthogonal resources (Rel-8/Rel-9 uses only 1 resource, and 2 resources may be used in Rel-10), potentially reducing the capacity of the PUCCH.

As shown in fig. 2, for the conventional 3GPP scheme, for the SORTD-enabled UE, a pair of PUCCH resources, namely PUCCH Resource-P0 (i.e. Antenna port 0 Resource) and PUCCH Resource-P1 (i.e. Antenna port 1 Resource) must be allocated, and this allocation procedure is quasi-static allocation by RRC. Even when SORTD is not necessary or helpful for improving reliability after the channel quality changes (e.g., the channels of the two uplink antennas are strongly correlated), the resources of this P1 antenna port cannot be released. Thereby wasting it.

Fig. 3 is an implementation manner of the scheme proposed in the present invention, as shown in fig. 3, a network side may share and allocate a P1 resource to a plurality of UEs, and the network side controls at any moment, by measuring the quality condition of an uplink channel, the UE actually needing the P1 resource to allow to start SORTD dual-antenna transmission, and other UEs not necessarily starting SORTD only need to use a P0 port to perform single-antenna transmission. It can be seen that by this new PUCCH Resource-P1 allocation scheme. The total PUCCH resources occupied by the same number of UE are reduced, in other words, the same number of resources are reduced, and more UE can be borne under the condition that the transmission stability is not basically affected by adopting the scheme in the embodiment of the invention. The invention is illustrated below with reference to examples:

embodiment one:

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 invention, and as shown in fig. 4, the flowchart includes the following steps:

step S402, distributing resources for more than two User Equipments (UE) in an access network;

step S404, indicating the resources allocated for the UE to the UE; the resource is used for the UE to transmit a physical uplink control channel PUCCH, and at least two of more than two UEs share the same Antenna port 1 resource when transmitting the PUCCH by using space orthogonal resource transmission diversity SORTD.

Wherein the above-mentioned resource indication method may be performed by the network side device, alternatively the above-mentioned method may be performed by the eNodeB. In the above embodiment, the same Antenna port1 resource shared by the UEs is essentially a PUCCH resource shared in the same Antenna port1 (i.e., a resource dedicated for transmitting PUCCH in Antenna port 1). In the following embodiments of the present invention, the Antenna port1 resources are substantially all PUCCH resources in Antenna port 1. Wherein the above two or more UEs include two UEs.

By the above embodiment, at least two UEs in the access network share one Antenna port1 resource, and each UE does not need to be configured with one Antenna port1 resource independently, so that the problems of high resource occupation consumption and low resource utilization rate in the related art can be solved, and the effects of reducing the resource occupation consumption and improving the resource utilization rate are achieved. In an alternative embodiment, indicating the resources allocated to the UE includes: sending a first indication message to the UE, wherein the first indication message is used for indicating Antenna port1 resources shared by the UE and other UEs; and sending a second indication message to the UE, wherein the second indication message is used for indicating whether the UE uses the Antenna port1 resource shared with other UEs.

Optionally, the first indication message includes a radio resource control RRC message. Optionally, the second indication message includes one of: downlink control messages DCI 1, DCI 1A, DCI, DCI 2A, DCI3, DCI3A.

In an alternative embodiment, allocating the resources for two or more UEs accessing the network includes: determining UE needing to allocate Antenna port1 resources in more than two UEs; determining the UE needing to share the resources and the UE not needing to share the resources in the UE needing to allocate the Antenna port1 resources; grouping the UE which needs to share the resources, wherein the number of the UE in each group is more than two; one Antenna port1 resource is allocated to each group of UEs, and one Antenna port1 resource is allocated to each UE that does not need to perform resource sharing. In this embodiment, UEs accessing the network may be classified into three types, where the first type UE only uses Antenna port0 resources to transmit PUCCH, the second type UE and the third type UE use Antenna port0 resources and Antenna port1 resources to transmit PUCCH, where the second type UE is a UE that needs to share Antenna port1 resources with other UEs, and the third type UE is a UE that is configured with Antenna port1 resources separately, i.e. does not share Antenna port1 resources with other UEs. In this embodiment, when determining a UE that needs to allocate Antenna port1 resources, the determination is performed according to the quality situation of the uplink channel, that is, it is determined that a UE whose quality of the uplink channel is lower than a predetermined threshold is a UE that needs to allocate Antenna port1 resources.

In an alternative embodiment, grouping UEs requiring resource sharing includes: the maximum number P of groups to be divided is determined by the following formula: p=t-M-2N, where T is the number of Antenna port 1 resources to be allocated in the network, 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, M is an integer greater than or equal to 2, and N is an integer greater than or equal to 0; and dividing the UE needing to share the resources into Q groups, wherein Q is a positive integer, and Q is less than or equal to P. In this embodiment, N may take 0, that is, there may be a case where there is no UE occupying Antenna port 1 resource alone. In addition, when the UEs needing to share resources are divided into Q groups, the number of UEs in different groups may be different, the UEs needing to share resources may be divided into Q groups according to the uplink channel quality of the UEs, the better the uplink channel quality, the better the UEs may share Antenna port 1 resources with more other UEs, and the UEs with poor uplink channel quality may only monopolize Antenna port 1 resources by themselves, or share Antenna port 1 resources with one (or two) other UEs.

As can be seen from the above embodiments, after the network determines the load-bearing UE condition according to the current load, the current UEs may be grouped. The resources of the PUCCH antenna ports P1 of UEs having 2 or more in at least one packet are the same. In the above embodiment, when the allocated resources need to be indicated by the indication information, this may be implemented specifically as follows:

A specific flag bit is placed in a specific downlink message (corresponding to the first indication message) and the UE is informed of the resource configuration through the downlink message, so that the UE knows that the PUCCH resource of P1 (corresponding to the Antenna port 1 resource) is shared with other UEs. The network side may also store this packet situation. For UEs in the packet, the network receives channel quality information transmitted by the UE, and performs uplink channel quality assessment by measuring uplink reference signals and the like. For a UE that performs SORTD with the most appropriate uplink channel quality (e.g., the uplink channel quality is poor and the antenna is not strongly correlated), the UE is notified that P1 resources can be used by setting a specific Bit to 1 in a specific DCI downlink message (corresponding to the second indication message described above) to perform uplink SORTD transmission. For other non-selected peer UEs, the UE is notified that P1 resources cannot be used by setting a specific Bit in a specific DCI downlink message to 0. Of course, setting the bit to 1 or to 0 is only a preferred embodiment, and may be indicated by other setting means in specific applications.

In an alternative embodiment, after indicating the resources allocated to the UE, the method further includes: determining that a new UE is accessed to the network, and/or disconnecting the UE accessed to the network from the network; and reallocating resources for the UE in the current network and indicating. That is, when the number of UEs in the access network changes, resources need to be reallocated to the UEs in the access network.

Example two

The method embodiment provided in the second embodiment of the present application may be executed in a mobile terminal, a computer terminal, or a similar computing device. Taking the mobile terminal as an example, fig. 5 is a block diagram of a hardware structure of the mobile terminal according to a PUCCH transmission method according to an embodiment of the present invention. As shown in fig. 5, the mobile terminal 50 may include one or more (only one is shown in fig. 5) processors 502 (the processors 502 may include, but are 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 appreciated by those of ordinary skill in the art that the configuration shown in fig. 5 is merely illustrative and is not intended to limit the configuration of the electronic device described above. For example, the mobile terminal 50 may also include more or fewer components than shown in fig. 5, or have a different configuration than shown in fig. 5.

The memory 504 may 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 invention, and the processor 502 executes the software programs and modules stored in the memory 504, thereby performing various functional applications and data processing, that is, implementing the method described above. Memory 504 may include high-speed random access memory, and may 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, the memory 504 may further include memory located remotely from the processor 502, which may be connected to the mobile terminal 50 via a network. Examples of such networks include, but are not limited to, the internet, intranets, local area networks, mobile communication networks, and combinations thereof.

The transmission means 506 is used to receive or transmit data via a network. The specific examples of the network described above 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 adapter (Network Interface Controller, simply referred to as NIC) that can connect to other network devices through a base station to communicate with the internet. In one example, the transmission device 506 may be a Radio Frequency (RF) module, which is used to communicate with the internet wirelessly.

In this embodiment, there is also provided a method for transmitting PUCCH, and fig. 6 is a flowchart of a method for transmitting PUCCH according to an embodiment of the present invention, as shown in fig. 6, where the flowchart includes the following steps:

step S602, determining resources allocated by a network;

step S604, the physical uplink control channel PUCCH is sent by utilizing the resources; wherein, at least two user equipments UE accessing the network share the same Antenna port 1 resource when transmitting PUCCH by using spatial orthogonal resource transmission diversity SORTD.

The above method may be applied to the terminal shown in fig. 5, that is, the execution subject of the above operation may be the terminal.

By the above embodiment, at least two UEs in the access network share one Antenna port1 resource, and each UE does not need to be configured with one Antenna port1 resource independently, so that the problems of high resource occupation consumption and low resource utilization rate in the related art can be solved, and the effects of reducing the resource occupation consumption and improving the resource utilization rate are achieved.

In an alternative embodiment, determining the resources allocated by the network includes: receiving a first indication message sent by a network; determining antenna port1 resources shared with the predetermined UE according to the first indication message; receiving a second indication message sent by a network, wherein the second indication message is used for indicating whether to use Antenna port1 resources shared with the predetermined UE; and determining the resources according to the second indication message.

Optionally, determining the resource according to the second indication message includes: when the second indication message is used for indicating to use the Antenna port1 resource shared with the preset UE, determining the resource as the pre-allocated Antenna port 0 resource and the Antenna port1 resource shared with the preset UE; when the second indication message is used for indicating that the Antenna port1 resource shared with the predetermined UE cannot be used, determining that the resource is the pre-allocated Antenna port 0 resource.

The predetermined UE corresponds to the other UE, that is, the other UE in the same packet as the terminal that receives the first indication message.

In the above embodiment, the terminal receives and stores PUCCH Resource-P0 and P1 resources (i.e., antenna port 0 and Antenna port 1 resources) of the network configuration. When the terminal receives a specific message (corresponding to the first indication message) sent from the network side, the terminal indicates that the terminal and other UEs share a certain PUCCH Resource-P1 Resource. The specific Bit is judged from the specific downlink DCI message (corresponding to the second indication message) and when the specific Bit position is 1, it indicates that the P1 corresponding resource is acquired. The next PUCCH transmission adopts the previously stored PUCCH Resource-P0 and P1 resources, and adopts SORTD dual-antenna transmission. When the specific Bit position is 0, the next time the PUCCH can only adopt PUCCH Resource-P0 to carry out single-antenna transmission. Of course, setting the bit to 1 or to 0 is only a preferred embodiment, and may be indicated by other setting means in specific applications.

Example III

In this embodiment, the technical details of the present invention will be mainly described, and in this embodiment, PUCCH Resource-P1 (or simply referred to as P1) corresponds to the aforementioned Antenna port 1:

as shown in the accompanying tables 1 to 4, different Resource allocation examples can be obtained by using different multiplexing coefficients for PUCCH Resource-P1. Wherein the resource multiplexing coefficient is defined as:

S＝[R_no_shared/R_shared]

wherein S represents a multiplexing coefficient, R_no_shared represents the number of P1 resources required by the sharing of the UE when the traditional 3GPP scheme is adopted, and R_shared represents the number of P1 resources required by the sharing of the UE by adopting the method. [] And the representation is an integer, and can be optionally rounded, rounded upwards or rounded downwards. Rounding is taken as an example here.

The additional table 4 is a resource occupation case without multiplexing, and as shown in the additional table 4, taking 11 UEs as an example, r_no_shared=11, when multiplexing is performed in the manner of the additional table 1, r_shared=6 is m= [11/6] = 2, and the multiplexing factor is 2, that is, half of the resources are saved compared with the prior art. For the attached table 2, m= [11/4] =3, where the multiplexing factor is 3, that is to say two thirds of the resources are saved compared to the prior art.

For the attached table 3, only another example of a hybrid allocation manner is presented, that is, the network side may also choose to enable the shared resource for some UEs, and some UEs do not use the shared resource. The amount of resources saved may be in half.

Table 1 (Main body multiplexing coefficient 2)

Table 2 (Main body multiplexing coefficient 3)

Table 3 (various multiplexing coefficient mixtures, 2 and 3)

Table 4 (no multiplexing scheme, i.e. 3GPP existing mode)

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

It is assumed that 4 UEs supporting SORTD access the network cell under the scenario that 6 PUCCH resources remain available at the network side. This case is described below:

since only 6 PUCCH resources are currently left, if 4 UEs activate SORTD of the 3GPP in the conventional manner, the number of resources required is 4×2=8, where the number of P1 resources is 4. Of the 6 resources that have been left over, 4 of them are P0 resources that must be allocated to 4 UEs. Only 6-4=2 resources remain that can be scheduled to P1. The multiplexing coefficient m=4/2=2, i.e. two UEs are required to share one P1 resource.

For UEs that have determined to share P1 resources, the corresponding UE may be notified first by a corresponding downlink RRC message that the P1 resources allocated to the corresponding UE are shared with other UEs, and whether the shared P1 resources can be used or not, and whether another condition is satisfied may be monitored from the DCI. For each of UE1 to UE4, the following key messages are sent, and examples of the key parts in the RRC message are as follows:

PUCCH-ConfigDedicated::＝SEQUENCE{

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

}

Two example message names and formats are given in the accompanying table 5.

Table 5

The shared mechanism proposed in the embodiment of the invention is Enabled by the SharedPUCCH-P1-Enabled being set to 1. At this time, the UE needs to monitor another bit in the DCI, for example, named as pucch hreshource-P1-Transmit, and when this bit is found to be 1, the UE uplink transmission adopts dual-antenna SORTD transmission, otherwise, adopts a single-antenna transmission mode. The format of the newly added field of the terminal monitoring DCI is exemplified as follows, where only one UE in each group has this field set to 1. For example:

DCI 1A/1/0/2A/2, etc.:

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 variation of each UE, the network side processes the channel information (including but not limited to Rank Indicator (RI) for short, channel quality Indicator (Channel Quality Indicator CQI for short) and the like) fed back by the terminal at regular intervals, and decides which UE in each group needs the P1 resource most in combination with the measurement of the uplink channel specific reference signal (including but not limited to SRS, PUCCH DMRS). Such periodic measurements and decisions ensure the adaptivity and timeliness of the method.

When a new UE is added, the network will re-evaluate the multiplexing condition and re-sort the resource allocation table. The foregoing critical process is restarted. It is ensured that the method in the embodiment of the invention can also adaptively change when the number of UE transmissions changes.

s708, UE1 and UE3 adopt network indication, uplink dual-antenna transmits PUCCH by utilizing resources allocated by P0 and P1, uplink of UE2 and UE4 adopts the allocated P0 resources, and single-antenna transmits PUCCH;

s710, each UE periodically transmits an uplink reference signal SRS and the like, and the auxiliary network measures the uplink channel of each UE;

S712, demodulating and measuring the uplink channel of each UE, finding out the UE with the worst uplink channel from each group according to the information of PUCCH and the result of SRS measurement, and distributing the UE with the worst uplink channel to use the dual-antenna to send PUCCH to improve the reliability, for example, the quality of UE2 and UE4 is the worst after measurement;
