Description

Method and device for configuring monitoring opportunity of PDCCH (physical Downlink control channel), electronic equipment and storage medium

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a method and an apparatus for configuring a monitoring opportunity of a PDCCH, an electronic device, a terminal device, a base station, and a storage medium.

Background

In the high frequency band, a subcarrier interval used by an Initial active Downlink (BWP) Bandwidth Part (Bandwidth Part, BWP) or a Type0 Physical Downlink Control Channel (Type 0-Physical Downlink Control Channel, type 0-PDCCH) or a CORESET (Control Resource Set) including the Type0-PDCCH or the CORESET0 may be 960kHz. The advantage of using a larger subcarrier spacing is that the Occupied Channel Bandwidth (OCB) requirement can be achieved with a smaller number of subcarriers.

The synchronization signal blocks may use different subcarrier spacings. Typically, the synchronization signal block may use a smaller subcarrier spacing, such as 120kHz, 240kHz, or 480kHz, so as to reduce the sampling rate when the user equipment UE detects the synchronization signal block, which is beneficial to reduce the complexity of the UE. At this time, how to determine the PDCCH (or Type 0-PDCCH) configuration is an urgent problem to be solved.

Specific embodiments of the present disclosure have been shown by way of example in the drawings and will be described in more detail below. The drawings and written description are not intended to limit the scope of the disclosed concepts in any way, but rather to illustrate the disclosed concepts to those skilled in the art by reference to specific embodiments.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the disclosure, as detailed in the appended claims.

Before explaining an application scenario and a principle of the method for configuring the monitoring opportunity of the PDCCH according to the embodiment of the present disclosure, some terms are explained first to facilitate the reader to understand the following description.

Taking Rel-15 NR (Release-15 New Radio, a 5G technology) as an example, in Rel-15 NR, a synchronization signal block is composed of a synchronization signal and a broadcast channel, so that a beam sweeping function is introduced.

The Synchronization signals may include Primary Synchronization Signal (PSS) and Secondary Synchronization Signal (SSS). User Equipment (UE) can obtain time-frequency synchronization of a cell and obtain a physical layer cell ID of the cell through a primary synchronization signal and a secondary synchronization signal, and this process is generally referred to as cell search.

The primary synchronization signal, the secondary synchronization signal, and a Physical Broadcast Channel (PBCH) constitute a synchronization signal block (SS/PBCH block, SSB).

Each synchronization signal block has a predetermined time domain position. This time domain position may also be referred to as a candidate synchronization signal block. The plurality of synchronization signal blocks constitute a synchronization signal burst (SS-burst) or a synchronization signal block burst (SS/PBCH block burst, SSB burst). The plurality of synchronization signal bursts form a synchronization signal burst set (SS-burst-set) or a synchronization signal block burst set (SS/PBCH block burst set, SSB burst set). The time domain positions of Lmax sync signal blocks are fixed within a 5ms window. The time domain position indices of the Lmax sync signal blocks are arranged consecutively from 0 to Lmax-1. The transmission time instant of a synchronization signal block within this 5ms window is fixed and the index is also fixed. Typically, a synchronization signal block within 5ms may constitute one synchronization signal burst.

Generally, the base station transmits the synchronization signal block by using a beam sweeping (beam sweeping), that is, the base station transmits the synchronization signal block at different time domain locations through different beams, and accordingly, the user equipment may measure the different beams and sense on which beam the received signal is strongest.

The pdcch carries scheduling and other control information, which specifically includes transport format, resource allocation, uplink scheduling grant, power control, uplink retransmission information, and the like.

Generally, the monitoring occasion of the PDCCH is included in a search space set (search space set), and the search space set further includes properties such as a search space type. The monitoring occasion of the PDCCH includes a period and an offset of a monitored time slot level, a starting symbol in the time slot, and the like. The Search space Set will typically bind a Set of Control resources (CORESET). CORESET includes properties such as frequency domain resources and duration (number of symbols) of PDCCH. One PDCCH consists of one or more CCEs. One PDCCH consists of n CCEs, and then its aggregation level is n.

Wherein the remaining minimum system information in Rel-15 NR includes main system information except the MIB. RMSI may also be referred to as SIB1.RMSI is carried in PDSCH, which is scheduled through PDCCH. The PDSCH carrying RMSI is generally referred to as RMSI PDSCH, and the PDCCH scheduling RMSI PDSCH is generally referred to as RMSI PDCCH.

The Search Space set in which the RMSI PDCCH is located is generally referred to as Type0-PDCCH Search Space set or Type0-PDCCH CSS (Common Search Space) set. In addition to the search space set of the RMSI PDCCH, other common search spaces or common search space sets include the search space set of the OSI PDCCH (Type 0A-PDCCH search space set or Type0A-PDCCH CSS set), the search space set of the RAR PDCCH (Type 1-PDCCH search space set or Type1-PDCCH CSS set), the search space set of the paging PDCCH (Type 2-PDCCH search space set or Type2-PDCCH CSS set), and the like.

Referring to fig. 1, fig. 1 is a schematic application scenario of a method for configuring a monitoring opportunity of a PDCCH according to an embodiment of the disclosure.

In the application scenario shown in fig. 1, each ue may establish a communication link with the base station, so as to perform data communication with the base station through the respective communication link.

And each user equipment acquires the paging message and the like corresponding to each user equipment through the monitoring time of each PDCCH.

In which fig. 1 exemplarily shows parts of user equipment such as mobile phones, computers and notebooks. Of course, the user equipment may also include ipads, smart bands, and in-vehicle terminals.

The following describes the technical solutions of the present disclosure and how to solve the above technical problems with specific embodiments. These several specific embodiments may be combined with each other below, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present disclosure will be described below with reference to the accompanying drawings.

According to an aspect of the embodiments of the present disclosure, a method for configuring a monitoring opportunity of a PDCCH applied to the foregoing scenario is provided in the embodiments of the present disclosure.

Referring to fig. 2, fig. 2 is a flowchart illustrating a method for configuring a monitoring opportunity of a PDCCH according to an embodiment of the present disclosure.

As shown in fig. 2, the method includes:

s101: determining a time slot or a starting time slot of a monitoring opportunity of the PDCCH, and/or determining a starting symbol of the monitoring opportunity of the PDCCH.

The execution subject of the embodiment of the present disclosure may be a device for configuring a monitoring opportunity of a PDCCH, and the device may be a user equipment, such as a mobile phone; of course, the device may also be a base station.

In the embodiment of the present disclosure, when the execution subject is taken as the user equipment for example, the monitoring occasion of the PDCCH may be determined by the user equipment, so that the user equipment performs PDCCH monitoring at the monitoring occasion of the PDCCH.

In some embodiments, the step may specifically include: the user equipment determines a time slot or a start time slot of a monitoring occasion of the PDCCH and/or determines a start symbol of the monitoring occasion of the PDCCH.

Similarly, in the embodiment of the present disclosure, when the execution subject is taken as the base station for example, the base station may determine the monitoring time of the PDCCH, and send the PDCCH to the user equipment at the determined monitoring time of the PDCCH, so that the user equipment performs PDCCH monitoring at the monitoring time of the PDCCH.

It should be noted that the PDCCH in the embodiment of the present disclosure may be a Type0-PDCCH, and the Type0-PDCCH is used for scheduling a System Information Block 1 (System Information Block 1, sib1), that is, when the ue monitors the Type0-PDCCH, the SIB1 is often not obtained, and the ue lacks System Information, so that the monitoring timing of the Type0-PDCCH is preset or can be derived according to a rule. The PDCCH in the embodiment of the disclosure can also be a Type0A-PDCCH, a Type1-PDCCH, a Type2-PDCCH or a Type3-PDCCH.

It is worth noting that the embodiments of the present disclosure intend to emphasize that the synchronization signal block and the PDCCH often use different subcarrier intervals, and the monitoring timing of the PDCCH may be different under different combinations of the synchronization signal block and the PDCCH subcarrier interval. That is, the specific PDCCH monitoring timing is related to the synchronization signal block and the subcarrier spacing specifically used by the PDCCH. In some scenarios, different synchronization signal Block and PDCCH subcarrier spacing combinations are configurable, such as indicated by a Master Information Block (MIB). At this time, the ue needs to determine a PDCCH monitoring occasion according to the indication. In other scenarios, different combinations of sync signal blocks and PDCCH subcarrier spacings are predetermined, such as one sync signal block and PDCCH subcarrier spacing combination in one frequency band (band) or frequency range (frequency range). At this time, the ue needs to determine a PDCCH monitoring occasion according to preset information.

It should be noted that, the method for acquiring the subcarrier spacing used by the synchronization signal block and the subcarrier spacing used by the PDCCH is not limited in the embodiment of the present disclosure.

In some embodiments, a time slot or a starting time slot of the monitoring occasion of the PDCCH is a time slot corresponding to the first symbol of the synchronization signal block. Or, the time slot corresponding to the first symbol of the synchronization signal block is a time slot or a starting time slot of a monitoring opportunity of a PDCCH associated with the synchronization signal block.

It should be noted that, since the monitoring occasion of the PDCCH may correspond to one time slot, it may also correspond to a plurality of consecutive time slots. Therefore, when the monitoring time of the PDCCH corresponds to a plurality of continuous time slots, the starting time slot of the monitoring of the PDCCH is determined as the time slot corresponding to the first symbol of the synchronization signal block; and when the monitoring opportunity of the PDCCH corresponds to one time slot, determining the time slot of the monitoring opportunity of the PDCCH as the time slot corresponding to the first symbol of the synchronization signal block. Or, when the monitoring occasion of the PDCCH corresponds to multiple consecutive time slots, the time slot corresponding to the first symbol of the synchronization signal block is the starting time slot of the monitoring occasion of the PDCCH associated with the synchronization signal block; when the monitoring opportunity of the PDCCH corresponds to a time slot, the time slot corresponding to the first symbol of the synchronization signal block is the time slot of the monitoring opportunity of the PDCCH associated with the synchronization signal block.

In the embodiment of the present disclosure, a time slot corresponding to a first symbol of a synchronization signal block is used as a time slot or a starting time slot of a monitoring opportunity of a PDCCH, so that a technical effect of rapid and convenient calibration can be achieved. Especially when the subcarrier spacing used by the synchronization signal block and the subcarrier spacing used by the PDCCH are different greatly, such as the combination of the subcarrier spacing used by the synchronization signal block and the subcarrier spacing used by the PDCCH is {120,960} kHz (i.e. the subcarrier spacing used by the synchronization signal block is 120khz, and the subcarrier spacing used by the PDCCH is 960 kHz), and the like, the synchronization signal block may span multiple time slots.

In some embodiments, when the even-indexed synchronization signal blocks and the odd-indexed synchronization signal blocks are non-consecutive, when the even-indexed synchronization signal blocks and the odd-indexed synchronization signal blocks are consecutive, and when the four synchronization signal blocks are consecutive, starting symbols of the monitoring occasions of the PDCCH are different. Non-consecutive and consecutive here means whether the symbols are consecutive or whether the symbol indices are consecutive.

Wherein the position of a symbol can be represented by its index in a slot.

It is worth mentioning that the even-indexed sync signal blocks and the odd-indexed sync signal blocks are non-consecutive, which can indicate that: the start symbols of the candidate synchronization signal blocks are 2 and 8 (since the synchronization signal block is 4 symbols, the symbols of the two synchronization signal blocks are discontinuous, and two symbols are separated from each other) in one slot at the subcarrier interval where the subcarrier interval of the synchronization signal block is a slot. In the embodiment of the present disclosure, the even-numbered synchronization signal blocks and the odd-numbered synchronization signal blocks are non-consecutive, but the present disclosure is not limited to the above manner.

It is worth mentioning that even indexed sync signal blocks and odd indexed sync signal blocks as consecutive can represent: the start symbols of the candidate synchronization signal blocks are 4 and 8 (since the synchronization signal block is 4 symbols, the symbols of the two synchronization signal blocks are consecutive according to the start symbols), and the start symbols of the candidate synchronization signal blocks are 16 and 20 (since the synchronization signal block is 4 symbols, the symbols of the two synchronization signal blocks are consecutive according to the start symbols) in the slots of even indices at the subcarrier interval of which the subcarrier interval is the slot, and in the slots of odd indices at the subcarrier interval of which the subcarrier interval is the slot. In the embodiment of the present disclosure, the even-numbered synchronization signal blocks and the odd-numbered synchronization signal blocks are consecutive, but are not limited to the above manner.

It is worth mentioning that four synchronization signal blocks as consecutive can represent: the start symbols of the candidate synchronization signal blocks are 8 and 12 and 16 and 20 (according to which the symbols of the four synchronization signal blocks are consecutive since the synchronization signal block is 4 symbols), the start symbols of the candidate synchronization signal blocks are 32 and 36 and 40 and 44 in two slots in which the index Modulo (Modulo) 4 is 0 and 1 at the subcarrier interval of the synchronization signal block (according to which the symbols of the four synchronization signal blocks are consecutive since the synchronization signal block is 4 symbols), and the index Modulo (Modulo) 4 is 2 and 3 in two slots in the subcarrier interval of the synchronization signal block. In the embodiment of the present disclosure, the four synchronization signal blocks are continuous to represent the above manner, but are not limited to the above manner.

In the embodiment of the present disclosure, when even-indexed synchronization signal blocks and odd-indexed synchronization signal blocks are not consecutive, the start symbol of the monitoring occasion of the PDCCH is located as close to the start of the synchronization signal block as possible, so that the synchronization signal blocks and the PDCCH close thereto are transmitted using one beam, and there is a large time interval (gap) between the two beams. Specifically, the method comprises the following steps:

in some embodiments, when even-indexed synchronization signal blocks and odd-indexed synchronization signal blocks are not consecutive, and a subcarrier interval used by the synchronization signal blocks is 120kHz and a subcarrier interval used by the PDCCH is 960kHz, then a start symbol of a monitoring occasion of the PDCCH associated with the even-indexed synchronization signal blocks may be 1 and a start symbol of a monitoring occasion of the PDCCH associated with the odd-indexed synchronization signal blocks may be 7. A starting symbol x (where x is an integer) indicates that the index of the starting symbol is x, starting with 0; or, the starting symbol is symbol x, and counting is started from symbol 0. All described in this manner below.

The scheme of the embodiment of the present disclosure may be applied to a case where a start symbol of the second synchronization signal block is 8 and the number of symbols of the control resource set of the PDCCH is 1. The number of symbols of the control resource set, which may also be referred to as the duration (duration) of the control resource set, is generally provided by a high-level parameter, and the symbols of the control resource set are hereinafter understood to be the duration of the control resource set.

In other embodiments, when even-indexed synchronization signal blocks and odd-indexed synchronization signal blocks are not consecutive, and the subcarrier spacing used by the synchronization signal blocks is 120kHz and the subcarrier spacing used by the PDCCH is 960kHz, the starting symbol of the monitoring opportunity of the PDCCH associated with the even-indexed synchronization signal block may also be 0, and the starting symbol of the monitoring opportunity of the PDCCH associated with the odd-indexed synchronization signal block may also be 6.

The scheme of the embodiment of the present disclosure may be applied to a case where a start symbol of the second synchronization signal block is 8 and the number of symbols of the control resource set of the PDCCH is 2.

In other embodiments, when even-indexed synchronization signal blocks and odd-indexed synchronization signal blocks are non-consecutive, and the subcarrier spacing used by the synchronization signal blocks is 120kHz and the subcarrier spacing used by the PDCCH is 960kHz, then the starting symbol of the monitoring occasion of the PDCCH associated with the synchronization signal blocks may be 1.

In other embodiments, when even-indexed synchronization signal blocks and odd-indexed synchronization signal blocks are not consecutive, and the synchronization signal blocks use 120khz and 480kHz apart for subcarriers, the start symbol of the monitoring occasion for the PDCCH associated with the even-indexed synchronization signal block may be 7, and the start symbol of the monitoring occasion for the PDCCH associated with the odd-indexed synchronization signal block may be 3.

The scheme of the embodiment of the present disclosure may be applied to a case where a start symbol of the second synchronization signal block is 8 and the number of symbols of the control resource set of the PDCCH is 1.

In other embodiments, when even-indexed synchronization signal blocks and odd-indexed synchronization signal blocks are non-consecutive, and the subcarrier spacing used by the synchronization signal blocks is 120khz and the subcarrier spacing used by the PDCCH is 480kHz, then the starting symbol of the monitoring occasion of the PDCCH associated with the synchronization signal block may be 7.
