Description

Data channel parameter configuration method and device

Technical Field

The present invention relates to the field of communications, and in particular, to a method and an apparatus for configuring a physical layer signaling.

Background

In a wireless communication system, a Physical Downlink Control Channel (PDCCH) plays a very important role, and Control information of a Physical layer is mainly used for: (1) sending downlink scheduling information (DL Assignment) to the UE so that the UE can receive a downlink data channel, wherein the data channel can bear some signaling messages of a high layer besides bearing data; (2) transmitting uplink scheduling information (UL Grant) to the UE so that the UE transmits an uplink data channel; (3) sending an aperiodic CQI reporting request; (4) informing the MCCH change; (5) sending an uplink power control command; (6) HARQ (hybrid Automatic Repeat request) related information; (7) carrying RNTI: this information is implicitly contained in the CRC, etc.

Information carried by the Downlink physical Control channel is called Downlink Control Information (DCI). DCI may indicate cell-level information, and is typically scrambled using si (system information) -RNTI/p (paging) -RNTI/ra (random access) -RNTI. There are also some other types of scrambling, such as TPC-PUCCH-RNTI, G-RNTI or SC-RNTI. It is also possible to indicate UE-level information, scrambled with C-RNTI/SPS C-RNTI/Temporary C-RNTI. Scrambling with different RNTIs actually represents that the message is directed to different user groups and different roles. If the RNTI information used in scrambling can not be obtained, the contents of the control messages can not be accurately solved; in general, the control channels and their corresponding search spaces can be classified into the following two categories, as shown in table 1:

table 1: control channel and search space type

Corresponding to two search spaces, a public search space and a special search space are provided, or the public search space and the special search space are called as two types of control channels, namely a public control channel and a special control channel; it is characterized by that the public search space/control channel is shared by several UEs, and the special search space/control channel is sent to a specific UE.

The PDCCH may directly carry some physical layer control information, as shown in fig. 1, and may also be used to transmit control information from a higher layer, or data information. This information from higher layers is considered physical layer data at the physical layer.

A part of important information in the PDCCH is used to indicate the relevant configuration of the data channel, and mainly includes the following aspects: resource allocation indication information; reference signal parameter indication information; rate matching information; and transmitting the parameter indication information. In nr (new Radio access technology), as the bandwidth is larger and larger, the design of the reference signal is more and more complex, the rate matching needs to consider more and more transmission parameters need to be indicated, and the DCI overhead is large. The physical layer signaling overhead is a precious resource, because the robustness requirement of the control channel is high, the code rate is low in general actual transmission, the modulation coding mode is also low, and a lot of actual transmission resources are occupied. If there are a large number of UEs, overhead waste may be severe, and the overhead of DCI needs to be optimized.

In this embodiment, when the parameter state set is unique, the receiving end may obtain the parameter state through pre-reservation, and when the parameter state set is multiple, the receiving end selects the parameter state to be used from the configurable parameter state set according to the indication information of the sending end.

In the present invention, a differential DCI design is introduced for a relevant configuration of a data channel, and the following embodiments describe the resource allocation signaling configuration, the demodulation reference signal configuration, and the configuration of a transmission parameter, respectively.

Example 1

In this embodiment, the present invention is specifically described in terms of resource allocation signaling configuration, and the following resource allocation manners are commonly used:

1. discontinuous resource allocation: resource blocks of a system bandwidth are sequentially divided into Resource groups from low to high according to the number of the Resource blocks, each P Resource Blocks (RB) are divided into a Resource block group, the Resource block numbers contained in the Resource block groups are different from each other, the number of the Resource blocks contained in the last Resource block group is not more than P, and the Resource Block Groups (RBG) are sequentially numbered from 0. Using bitmap to represent the allocation condition of each resource block group (n continuous bits, each bit corresponds to a resource group, 1 represents allocation, 0 represents no allocation);

2. continuous resource allocation: any continuous resource block can be determined by the initial position and the number of the resource blocks, and in order to reduce signaling overhead, each tree node of the method for jointly encoding the initial position and the number of the resource blocks represents a resource condition corresponding to all sub-nodes, for example: node 13 indicates that the allocated resources are RB1, RB2, and RB 3;

regardless of the method, overhead increases as the bandwidth becomes larger. Since the bandwidth of NR is very large, the overhead is much larger, for example, LTE is maximum 20MHz per carrier frequency, but NR can reach 100MHz per carrier frequency. The main purpose of flexible resource allocation is to achieve frequency domain selective fading. But adding flexibility when the bandwidth is large to a certain extent does not bring extra effect.

Therefore, the parameters of resource allocation can be pre-configured and defined in a manner, for example:

1) configuring RB/REG set which can be configured when limiting resource allocation is configured;

2) the configuration defines the number of RBs/REGs that can be allocated consecutively;

3) the configuration defines the number of all RBs/REGs that can be allocated;

4) if the resource allocation of the time domain exists, the limit can be configured in advance, and the number of the time domain symbols which can be allocated can be determined;

5) the configuration defines all allocable time domain symbols, slots.

One way is to directly perform configuration specification on the above parameters, and determine the size of the resource allocation indication signaling in the DCI according to the values of the parameters. Another way is to determine these parameters by some pre-determined convention.

The above-mentioned restriction is generally proposed as a UE-level configuration, and can be further extended to the configuration of DCI level, service level, and channel level, and the specific configuration restriction method:

1) determining the resource allocation parameter according to the service type:

URLLC (Ultra-relay and Low Latency Communication) traffic uses resource allocation parameter configuration definition 1; mtc (passive machine type of communication) service use resource allocation parameter configuration definition 2, and eMBB (enhanced mobile broadband) service use resource allocation parameter configuration definition 3;

URLLC traffic or mtc traffic, which does not have a strong necessity for highly flexible resource allocation at such a large bandwidth. And there are also different characteristics between URLLC and mtc services and eMBB services, for example, TB blocks are different in size, the number of transmission layers is different, and there is no need to have the same resource allocation.

2) Determining the resource allocation parameters according to the DCI type, the DCI scrambling mode, the DCI position and the DCI reference demodulation pilot frequency sequence:

DCI type 1 uses resource allocation parameter configuration definition 1; DCI type 2 uses resource allocation parameter configuration definition 2, DCI type 3 uses resource allocation parameter configuration definition 3;

DCI scrambling scheme 1 uses resource allocation parameter configuration definition 1; the DCI scrambling mode 2 uses resource allocation parameter configuration limitation 2, and the DCI scrambling mode 3 uses resource allocation parameter configuration limitation 3;

DCI position 1 uses resource allocation parameter configuration definition 1; DCI position 2 uses resource allocation parameter configuration definition 2, DCI position 3 uses resource allocation parameter configuration definition 3;

DCI reference demodulation pilot sequence 1 uses resource allocation parameter configuration definition 1; the DCI reference demodulation pilot sequence 2 uses a resource allocation parameter configuration definition 2, and the DCI reference demodulation pilot sequence 3 uses a resource allocation parameter configuration definition 3;

the differences in DCI type, scrambling code, location, and reference signal sequence generally mean that there are differences in the content of control information, transmission technology, and the like. Such as paging message, system message, and random access message, the variation range of the content size is also different. It is not necessary to have the same resource allocation design, nor the same resource allocation design as the data information.

3) Determining the resource allocation parameters according to the channel/signal type:

a Physical Downlink Shared Channel (PDSCH) is defined by a resource allocation parameter configuration 1; the CSI-RS signal uses resource allocation parameter configuration definition 2.

A Physical uplink data channel (PUSCH) is defined with a resource allocation parameter configuration 1; srs (sounding reference signal) signal is defined using resource allocation parameter configuration 2.

PUSCH uses resource allocation parameter configuration definition 1; PDSCH uses resource allocation parameter configuration definition 2.

Generally, the resource allocation manners of the downlink data channel PDSCH and the downlink measurement reference pilot CSI-RS (channel state information reference signal) are not necessarily limited to be the same, and the CSI-RS may need to be more flexible. The same resource allocation modes of the uplink data channel PUSCH and the uplink measurement reference pilot SRS are not necessarily limited to be the same, and the SRS may need to be more flexible.

4) Determining the resource allocation parameter according to a Slot format (Slot format):

slot format 1 uses resource allocation parameter configuration definition 1; slot format 2 signals use resource allocation parameter configuration definition 2.

The slot format configuration is similar to the subframe structure configuration in LTE. Time domain symbol resources of an uplink and a downlink are specified, the number of downlink symbols is large and the number of the uplink is small in some cases, and the number of the downlink symbols is small and the number of the uplink is large in some cases. Different cases consider resource allocation parameter definitions in the frequency domain, respectively.

When the UE initially accesses, there may be a period of time when physical layer data needs to be transmitted, but the RRC configuration cannot be obtained, at this time, the resource allocation parameters may be defined as follows, so as to reduce overhead and improve performance: this limitation is actually a pre-agreed, e.g., determining the time-frequency resource locations that the data channel can be allocated to according to the bandwidth occupied by the broadcast channel PBCH/synchronization signal SS/or other periodic reference signals (e.g., CSI-RS).

It is typically the case that the frequency domain RB resources that can be used for data channel transmission are the same as the RB resources occupied by the PBCH/SS. Or a subset of the RBs occupied by the PBCH/SS, or the RBs occupied by the PBCH/SS and the continuous RBs on both sides of the PBCH/SS, wherein the number of the RBs occupied by the PBCH/SS is not more than twice of the number of the RBs occupied by the PBCH/SS. The temporal position may also be similarly predefined.

The method can not only reduce DCI overhead, but also better estimate the time frequency offset by using PBCH or SS or other periodic reference signals by the data channel, thereby obtaining better performance.

Example 2

The present embodiment specifically describes the present invention in terms of demodulation reference signal configuration. There are various configurations of NR data channel reference demodulation pilots, including:

configuring a port multiplexing mode; such as frequency division multiplexing, time domain code division multiplexing, frequency domain code division multiplexing, time frequency domain code division multiplexing, etc.

Configuring the number of symbols; such as one symbol or two symbols.

Configuring port numbers; such as the numbering rules of the ports.

The arrangement of pattern density; for example, the density is

port

2, 3, 6 RE/RB/port.

Additional demodulation pilot configuration: the presence or absence of an additional demodulation pilot.

Pilot frequency power configuration: relative power of pilot REs and data REs.

When configuring these parameters, the parameter configuration ranges may be defined according to different situations. When defining, it can be defined independently or jointly for different demodulation pilot parameters.

1) Determining pilot parameters according to the traffic type:

URLLC service uses demodulation pilot frequency parameter configuration definition 1; the mtc service uses a demodulation pilot parameter configuration definition 2, and the eMBB service uses a demodulation pilot parameter configuration definition 3.

For example, the pilot density of the mtc service can only select 2, 3 REs/RB/port; while URLLC can only select 3, 6RE/RB/port, eMBB can select 2, 3, 6 RE/RB/port. Which configuration is employed is related to its service-specific characteristics.

For another example, the mtc service corresponds to port multiplexing option set 1, and the URLLC service corresponds to port multiplexing option set 2.

For another example, the pilot-to-data power ratio for the eMBB service is 1, 2, the pilot-to-data power ratio for the URLLC service is 2, and the pilot-to-data power ratio for the mtc service is 1.

2) Determining the reference pilot configuration parameter according to the DCI type, the DCI scrambling mode, the DCI position and the DCI reference demodulation pilot sequence:

the DCI type 1 uses demodulation pilot frequency parameter configuration or configuration set 1 corresponding to the data channel scheduled by the DCI type 1; the DCI type 2 uses a demodulation pilot frequency parameter configuration or configuration set 2 corresponding to the data channel scheduled by the DCI type 2, and the DCI type 3 uses a demodulation pilot frequency parameter configuration or configuration set 3 corresponding to the data channel scheduled by the DCI type 3;

the DCI scrambling mode 1 uses demodulation pilot frequency parameter configuration or configuration set 1 corresponding to the scheduled data channel; the DCI scrambling mode 2 uses a demodulation pilot frequency parameter configuration or configuration set 2 corresponding to the scheduled data channel, and the DCI scrambling mode 3 uses a demodulation pilot frequency parameter configuration or configuration set 3 corresponding to the scheduled data channel;

the transmission position 1 of DCI uses demodulation pilot frequency parameter configuration or configuration set 1 corresponding to the data channel scheduled by the DCI; the transmission position 2 of DCI uses demodulation pilot frequency parameter configuration or configuration set 2 corresponding to the data channel scheduled by the DCI;

a control channel reference demodulation pilot sequence 1 for transmitting DCI corresponds to a data channel demodulation pilot parameter configuration or configuration set 1 scheduled by the control channel reference demodulation pilot sequence; a control channel reference demodulation pilot frequency sequence 2 for transmitting DCI corresponds to the data channel demodulation pilot frequency parameter configuration or configuration set 2 scheduled by the control channel reference demodulation pilot frequency sequence;

the differences in DCI type, scrambling code, location, and reference signal sequence generally mean that there are differences in the content of control information, transmission technology, and the like. Such as paging message, system message, and random access message, the importance, transmission requirement, and object oriented may be different. It is not necessary to have the same demodulation reference signal configuration.

The present embodiment specifically describes the present invention in terms of the configuration of transmission parameters.

The transmission parameters include PRB bundling parameters, QCL (Quasi-co-location) indication parameters, cbg (coded group) parameters, HARQ parameters, MCS parameters, and the like. This information also requires multiple DCI bits for configuration indication. We can also consider reducing the overhead in a similar way as before, such as:

the bundling granularity of PRB bundling has various choices, for example, the bundling granularity is: 1,2,4.

A corresponding binding granularity set can be determined according to the service type, for example, PRB bundling binding granularity of the eMBB is 1, 2, 4; the PRB bundling binding granularity of the URLLC is 2, 4. The binding granularity or the optional configuration set of the binding granularity can also be determined according to the DCI type, the DCI scrambling mode, the DCI position and the DCI reference demodulation pilot sequence.

The QCL indicates parameters mainly including the type of QCL and QCL relationship. The method can be determined according to the service type, or according to the DCI type, the DCI scrambling mode, the DCI position and the DCI reference demodulation pilot frequency sequence

CBG parameters mainly comprise the number of CBGs, a CB division mode and a CB mapping mode; the HARQ parameters mainly include: HARQ retransmission version number and retransmission process number; the MCS parameters mainly include an MCS table. These parameters or their optional configuration sets can be determined according to the service type, or according to the DCI type, the DCI scrambling mode, the DCI position, the DCI reference demodulation pilot sequence

Through the configuration mode described in the above embodiment, the technical effect of saving DCI overhead can be achieved, and some features of the PDCCH are used to implicitly indicate parameters of the PDSCH.
