Description

Channel transmission method and device and computer storage medium

Technical Field

The present application relates to the field of communications technologies, and in particular, to a channel transmission method and apparatus, and a computer storage medium.

Background

A Physical Downlink Control CHannel (PDCCH) of a Long Term Evolution (Long Term Evolution, LTE) system is used to carry scheduling information and other Control information. The Control region of each downlink subframe may have a plurality of PDCCHs therein, and the size of the Control region is determined by a Physical Control mode Indicator CHannel (PCFICH) and occupies 1 to 4 Orthogonal Frequency Division Multiplexing (OFDM) symbols. The transmission of one Control Channel occupies one Control Channel Element (CCE) or multiple consecutive CCEs, each CCE consists of 9 Resource Element Groups (REGs), and a REG included in a CCE of a PDCCH is a REG that is not used for carrying a PCFICH and a PHICH. A User Equipment (UE) monitors a PDCCH candidate resource location (candidate) set in a non-DRX (non-discontinuous reception) subframe, that is, attempts to decode each PDCCH in a search space according to a Downlink Control Information (DCI) mode (format) to be monitored.

To extend the capacity of PDCCH, evolved PDCCH (epdcch) was introduced in release 11 (Rel-11). The EPDCCH is transmitted in a data region in a subframe and cannot occupy a transmission space of the PDCCH. The terminal configured with the EPDCCH detects and receives the EPDCCH in a set of Physical Resource Block (PRB) configuration in each subframe.

For an Enhanced Machine Type Communication (EMTC) UE, it detects a receiving Machine PDCCH (Machine PDCCH, MPDCCH) on one or more subframes (subframes) configured by a higher layer.

In the existing LTE system, a Transmission Time Interval (TTI) length is fixed to 1ms, and one or more PDCCHs are Transmitted on the first N OFDM symbols of each TTI or on a set of PRB pairs (pair) of a data region or on multiple consecutive or non-consecutive subframes, and a UE blindly detects its own PDCCH on a Common Search Space (CSS) of each non-DRX subframe and a Search Space (USS) of a user equipment according to desired information. Both the downlink control channel transmitted in the CSS and the downlink control channel transmitted in the USS employ all Common Reference Signals (CRSs) over the entire frequency domain as demodulation pilots. In the 5G system, different search spaces have different blind detection periods, and Demodulation Reference Signal (DMRS) pilot structures used for demodulating downlink control channels transmitted in the different search spaces are different.

Detailed Description

In the LTE system, a terminal needs to detect a reception downlink control channel on a Common Search Space (CSS) within each non-DRX subframe (subframe) and a Search Space (USS) of a user equipment. In a future 5G system, the set of control resources for transmitting the downlink control channel may only have the USS, only the CSS, or both the CSS and the USS. Moreover, the downlink control channel transmitted in the CSS and the downlink control channel transmitted in the USS have different DMRS pilot structures and different beam directions, for example, different QCLs related to DMRSs. The technical scheme provided by the embodiment of the application provides how to inform the terminal of the search space type existing in the CORESET, and how to detect and receive the downlink control channel by the terminal.

The base station configures a search space type existing in a COntrol REsource SET (core SET) through an explicit signaling, and determines a sequence of receiving a downlink COntrol channel in the core SET through a notification mode of the explicit signaling configuration or a protocol predefined mode.

Referring to fig. 1, at a terminal side, a channel transmission method provided in an embodiment of the present application includes:

s101, determining a search space type existing in a control resource set through a signaling sent by a network side;

and S102, carrying out channel transmission according to the search space type existing in the control resource set.

In the embodiment of the application, the search space type existing in the control resource set can be determined through signaling sent by the base station.

Optionally, the signaling includes Radio Resource Control (RRC) signaling, or Remaining system information (RMSI), or Random Access Response (RAR) in a Random Access procedure.

That is to say, in the embodiment of the present application, a terminal receives an explicit signaling sent by a base station, determines a search space type existing in one or more CORESET, and detects and receives different types of downlink control channels in the search space according to a base station notification or a predefined order.

For example, the terminal receives Radio Resource Control (RRC) signaling (signaling) sent by the base station, and determines a search space type existing in the CORESET.

Specifically, the base station informs the terminal of the existence of USS, CSS, G-CSS or any combination of the USS, the CSS, the G-CSS and the G-CSS through RRC signaling.

Alternatively, for example, the base station notifies the terminal of Remaining system information (RMSI) and transmits whether the USS exists in the CORESET of the PDCCH that schedules the RMSI.

When a USS is present within the CORESET transmitting the PDCCH scheduling the RMSI, the USS is transmitted on a set of physical resources predefined by the protocol, for example comprising N logical CCEs within the CORESET. The number and type of PDCCH candidates included in the USS may be predefined by a protocol. For example: there are M1 PDCCH candidates with Aggregation Level (AL) 1 and M2 PDCCH candidates with AL 2. Wherein M1 and M2 are positive integers.

Or, when a USS exists within the CORESET of the PDCCH transmitting the RMSI, the USS is transmitted on a set of physical resources notified by the base station, for example, a starting position of a logical CCE number constituting the USS, or an offset value, or a specific CCE index (index) is notified through the RMSI or the RAR. Further, AL and the number of PDCCH candidates transmitted in the USS may also be explicitly notified to the terminal by the base station or predefined.

Alternatively, for example, the base station notifies the terminal whether the USS exists in the core set of the PDCCH for scheduling the RMSI through a Random Access Response (RAR) in the Random Access procedure.

When a USS exists within the CORESET transmitting the PDCCH scheduling RMSI, the USS consists of the PDCCH candidate predefined by the protocol.

Alternatively, when a USS exists in the CORESET of the PDCCH transmitting the RMSI, the PDCCH candidate included in the USS is notified by the base station, for example, by RAR, to notify the specific PDCCH candidate constituting the USS.

In summary, optionally, when the search space type present in the control resource set for transmitting PDCCH scheduling RMSI includes USS, the USS is transmitted on a predefined or network-side notified physical resource.

and detecting and receiving different types of downlink control channels in different search spaces in the control resource set according to a predefined detection receiving sequence or a detection receiving sequence notified by a network side.

PDCCH carrying a time slot mode indication SFI;

a PDCCH dedicated to user equipment for carrying data scheduling information;

and the PDCCH carries other information besides the information.

Specifically, for example:

in a CORESET, a terminal detects and receives downlink control channels in different search spaces according to a predefined detection receiving sequence or a detection receiving sequence notified by a base station.

There may be downlink control channels for various transmission scenarios in a CORESET, corresponding to different search spaces, including but not limited to the following downlink control channels:

a common (common) PDCCH or a group (group) common PDCCH for carrying RMSI scheduling information or Paging scheduling information or RAR scheduling information, which may be denoted as P1 for convenience;

a group common PDCCH carrying a Slot Format Indication (SFI), which may be denoted as P2 for convenience;

a user equipment-specific (UE-specific) PDCCH carrying data scheduling information, which may be denoted as P3 for convenience;

the group common PDCCH carrying other information (e.g., a pre-estimation indication (pre-estimation indication), a power control indication (power control indication)) may be denoted as P4 for convenience.

When there are a plurality of types of downlink control channels in one CORESET, the terminal detects reception of the downlink control channels in a predefined order, for example, first detects reception P1, second detects reception P2, then detects reception P3, and finally detects reception P4.

A core set may include parts from P1 to P4, and may also include other downlink control channels, which are not limited herein.

In addition, it should be noted that the predefined detection receiving order is not limited to the above order, and other detection receiving orders are not excluded, and may be determined according to actual needs.

Or, when multiple types of downlink control channels exist in one core set, the terminal detects the different types of downlink control channels according to the sequence notified by the base station.

The base station may notify the terminal of detecting the sequence of receiving the downlink control channel through a higher layer signaling, or RMSI, or RAR.

For example, if N different types of downlink control channels coexist in the system, for example, if N is 4, the terminal may indicate the reception detection order by an N × ceil (log2(N)) bit, taking the reception detection order as an example, see table one below, where the indication field is 00011011.

Alternatively, a combination of a set of detection orders is predefined in the system, and the base station indicates one of the sets as an order for detecting the received downlink control channels through explicit signaling. For example, the four sequences shown in table two below are predefined. The base station instructs the terminal to detect the order of receiving the downlink control channels in a CORESET through the 2-bit information

Correspondingly, on the network side, referring to fig. 2, an embodiment of the present application provides a channel transmission method, including:

s201, determining a signaling for notifying a terminal of a search space type existing in a control resource set;

s202, the signaling is sent to the terminal.

In the embodiment of the present application, for example, the base station may perform steps S201 and S202.

Optionally, the method further comprises:

and sending the downlink control channel in the control resource set according to the search space type.

Optionally, the method further comprises:

PDCCH carrying a time slot mode indication SFI;

a PDCCH dedicated to user equipment for carrying data scheduling information;

and the PDCCH carries other information besides the information.

An illustration of some specific embodiments is given below.

Example 1:

the base station informs the terminal of the type of the search space existing in the CORESET through UE specific RRC signaling. For example, the base station informs a CORESET of the type of search space present therein via a 2-bit message. As shown in table three below. That is, 00 indicates that only the USS exists in CORESET, 01 indicates that only the CSS exists in CORESET, and 10 indicates that both the USS and the CSS exist in CORESET.

bit field	Means of

01	CSS only
		10	Simultaneous presence of USS and CSS
11	reserved

Watch III

Further, the base station notifies the terminals of the CCE index start positions of the CSS and the USS through RRC signaling.

When the CORESET has multiple search spaces, the terminal needs to detect and receive different types of downlink control channels. For example, the following control channel types may be included:

a common PDCCH or a group common PDCCH for carrying RMSI scheduling information or Paging scheduling information or RAR scheduling information, which is conveniently denoted as P1;

a group common PDCCH carrying SFI, conveniently denoted as P2;

a UE-specific PDCCH bearing data scheduling information, conveniently denoted as P3;

the group common PDCCH carrying other information (e.g., pre-indication, power control indication) is denoted as P4 for convenience.

In this case, the terminal detects the order of receiving the different types of downlink control channels, and can determine the order as follows:

mode 1: the sequence in which the terminal detects reception of the downlink control channel is determined in a protocol-predefined manner, for example, the terminal detects reception P1 first, reception P2 second, reception P3 second, and reception P4 last. Of course, the predefined order is not limited thereto. In addition, the technical solution provided in the embodiment of the present application is not limited to that all the 4 downlink control channel types are present in the same CORESET, for example, only P1 and P3 may exist, and the terminal first detects received P1 and then detects received P3.

Mode 2: and the terminal detects and receives the downlink control channels according to the downlink control channel detection and reception sequence configured by the base station. Taking P1, P2, P3, and P4 as examples, the order of detecting the reception of the downlink control channels can be determined in one of the following two ways.

The base station indicates the detection sequence through 8-bit information, wherein the highest bit indicates the type of the downlink control channel with the highest priority, and the lowest bit indicates the type of the downlink control channel with the lowest priority. For example 00 denotes P1, 01 denotes P2, 10 denotes P3 and 11 denotes P4. If the detection receiving sequence notified by the base station is P1P2P3P4, the 8bit information is 00011011.

The base station indicates a combination of the detected reception orders by means of the indication table index. For example, the receiving sequence is detected in 4 predefined in the system, which is specifically shown in table four below. The base station indicates four downlink control channel detection receiving sequences through 2-bit indication information.

bit field	bit field schematic

01	P1P3P2P4
		10	P3P1P2P4
11	P2P1P3P4

Example 2:

as in embodiment 1, the signaling for notifying the downlink control channel detection reception order may be carried through an RMSI or an RAR.

Example 3:

the base station notifies the terminal that a UE-specific search space (specific search space) exists in the CORESET transmitting the PDCCH scheduling the RMSI. The base station may notify that a UE specific search space (UESS) exists in the CORESET through RMSI or RAR. For example, whether UESS exists is indicated by 1-bit indication information.

The number and location of PDCCH candidates contained by the UESS within the core set (RMSI-core set) for transmitting the PDCCH scheduling RMSI is predefined by the protocol. For example, the protocol specifies a USS within RMSI-CORESET, including PDCCH candidates with AL of 4 and 8, respectively, and the number of candidates under each AL of 4 and 4, respectively. And the starting location starts from the first logical CCE within the CORESET.

Alternatively, the number and location of PDCCH candidates included in the RMSI-core set by the UESS are notified by a Physical Broadcast Channel (PBCH) or RAR. For example, the PBCH or RAR notifies the terminal of the starting position of PDCCH candidate included in the UESS in the RMSI-CORESET, the number of candidates included, and the like.

When a plurality of types of downlink control channels are included in the RMSI-core set, the terminal determines the order of detecting and receiving the downlink control channels according to the method as described in embodiment 1.

Example 4:

as in embodiment 1-3, after determining the blind detection sequence of the downlink control channel, the terminal detects and receives the downlink control channel according to the determined blind detection sequence. After the terminal detects and receives the downlink control channel, the terminal does not detect and receive other types of downlink control channels subsequently.
