Description

Configuration method, device and base station for control resource set and PDCCH monitoring opportunity
Technical Field
The present invention relates to the field of wireless communication technologies, and in particular, to a method, an apparatus, and a base station for configuring a control resource set and a PDCCH monitoring opportunity.
Background
In the 5G system, a synchronization signal, a broadcast channel, is transmitted in a synchronization signal block manner, and a beam sweeping function is introduced. Primary Synchronization Signal (PSS), Secondary Synchronization Signal (SSS), and Physical Broadcast Channel (PBCH) are in a Synchronization Signal block (SS-block). Each synchronization signal block can be regarded as a resource of one beam (analog domain) in a beam sweeping (beam sweeping) process. A plurality of sync signal blocks constitute a sync signal burst (SS-burst). The synchronization signal burst can be viewed as a block of resources in a relative set that contains multiple beams. The plurality of synchronization signal bursts form a set of synchronization signal bursts (SS-burst-set). The synchronization signal block is repeatedly transmitted on different beams, which is a beam scanning process, and through the training of beam scanning, the user equipment can sense on which beam the received signal is strongest.
In an idle state, the ue needs to monitor a Physical Downlink Control Channel (PDCCH), blindly detect a common search space thereof, and obtain Downlink Control Information (DCI) therein, so as to receive a common Control message, such as Remaining Minimum System Information (RMSI), a paging message, and the like, in an indicated Physical Downlink Shared Channel (PDSCH). Let us call the PDCCH that the ue needs to monitor in idle state as the common control channel. The common control channel may use the timing of the beams of the synchronization signal block to broadcast information in a beam-sweeping manner as well. The resources of the PDCCH are referred to as a Control Resource Set (CORESET).
The base station carries a Master Information Block (MIB) in the PBCH. The MIB may instruct the ue to know the configuration of the core set in the idle state, so that the ue may blindly detect the PDCCH in the core set in the idle state to obtain the RMSI, and so on. We call this CORESET the first CORESET.
The RMSI may indicate that the user equipment knows the configuration of another type of core set in the idle state, so that the user equipment may blindly check the PDCCH within the core set in the idle state to acquire a paging message, etc. We call this CORESET the second CORESET.
The network sends the configuration of the first CORESET and/or the second CORESET (hereinafter, referred to as idle CORESET collectively) to the UE, including the bandwidth, frequency domain position, time domain position (such as symbol index in the slot) and the like of the idle CORESET.
The network needs to send the configuration of the idle state CORESET to the user equipment, and also needs to send the configuration of the monitoring opportunity of the PDCCH to the user equipment. In general, the configuration of the monitoring occasion of the PDCCH includes a monitoring occasion period, a monitoring occasion duration, and an offset of the monitoring occasion. On the other hand, the monitoring occasion of the PDCCH may be defined by a monitoring window of the PDCCH. In general, the configuration of the monitoring window of the PDCCH includes a monitoring window period, a monitoring window duration, and an offset of the monitoring window. The first and second CORESET respectively correspond to a first PDCCH monitoring occasion and a second PDCCH monitoring occasion (hereinafter collectively referred to as an idle PDCCH monitoring occasion).
Generally, for the first CORESET configuration and the first PDCCH monitoring occasion configuration, the configuration information needs to be carried in the MIB; for the second CORESET configuration and the second PDCCH monitoring occasion configuration, the configuration information needs to be carried in the RMSI. Since the number of bits that the MIB and the RMSI can carry is small, no matter the first CORESET configuration and the first PDCCH monitoring occasion configuration, or the second CORESET configuration and the second PDCCH monitoring occasion configuration, a better design is required to reduce overhead and ensure flexibility.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
An embodiment of the present invention provides a method for configuring a control resource set and a PDCCH monitoring occasion, as shown in fig. 1, the method includes:
s11, sending PDCCH monitoring opportunity configuration to user equipment, wherein the PDCCH monitoring opportunity configuration indicates the PDCCH monitoring opportunity and the time offset of a synchronization signal block, or the PDCCH monitoring opportunity configuration indicates the PDCCH monitoring opportunity and the absolute offset of the initial position of a system frame number 0, or the PDCCH monitoring opportunity configuration and SMTC jointly indicate the incidence relation between the PDCCH monitoring opportunity and the synchronization signal block.
Wherein the PDCCH monitoring occasion is configured as a PDCCH monitoring window configuration.
Optionally, the starting slot is the first slot of a system frame, or a slot predefined by a protocol, or a slot specified by signaling.
And the time offset for indicating the PDCCH monitoring opportunity and the synchronization signal block and the frequency domain offset of the CORESET and the synchronization signal block are jointly coded.
The method for configuring a control resource set and a PDCCH monitoring opportunity provided by the embodiment of the invention sends PDCCH monitoring opportunity configuration to user equipment, wherein the PDCCH monitoring opportunity configuration indicates the time offset of the PDCCH monitoring opportunity and a synchronization signal block, or the PDCCH monitoring opportunity configuration indicates the absolute offset of the PDCCH monitoring opportunity and the initial position of a system frame number 0, or the PDCCH monitoring opportunity configuration and SMTC jointly indicate the incidence relation of the PDCCH monitoring opportunity and the synchronization signal block, so that better configuration of the control resource set and the PDCCH monitoring opportunity can be realized, signaling overhead is reduced, and flexibility is ensured.
The following describes the configuration method of the control resource set and the PDCCH monitoring occasion according to the present invention in detail.
The first CORESET and the first PDCCH scheduled PDSCH it contains are also transmitted in swept beams and their beams are associated with the beams of the synchronization signal block. Specifically, the association relationship refers to a Demodulation Reference Signal (DMRS) of a PDCCH transmitted in the first CORESET and a DMRS of a scheduled PDSCH thereof, and the associated synchronization Signal block is Quasi co-located (QCL). In some cases, the beam of the first CORESET may be 1 to 1 associated with the beam of the synchronization signal block. In this case, the most straightforward way is to frequency-division multiplex the first CORESET with the sync signal block. Thus, the first CORESET and the sync block can be transmitted simultaneously within one beam. However, in some cases, the bandwidth of the carrier is not enough to frequency-division multiplex the first CORESET and the synchronization signal block, and the first CORESET needs to be time-division multiplexed with the synchronization signal block. Thus, either the first CORESET or the synchronization signal block is transmitted within a beam.
The two situations correspond to two typical scenarios. The flexible support of the two scenarios can be achieved through the first CORESET configuration and the first PDCCH monitoring opportunity configuration. That is, the network indicates whether the first CORESET and the synchronization signal block are frequency division multiplexed or time division multiplexed through the "first CORESET configuration and the first PDCCH monitoring occasion configuration". More generally, the network indicates the relative frequency domain locations of the first CORESET and the synchronization signal block by a "first CORESET configuration and a first PDCCH monitoring occasion configuration", wherein the relative frequency domain locations of the first CORESET and the synchronization signal block may be X resource blocks with a frequency domain offset of the first CORESET and the synchronization signal block, wherein X is not 0.
Specific example 1: the relative frequency domain locations of the first CORESET and the synchronization signal block may be X resource blocks with a frequency domain offset of a first resource block of the first CORESET and a first resource block of the synchronization signal block, where X is not 0.
Specific example 2: the relative frequency domain locations of the first CORESET and the synchronization signal block may be Y subcarriers with a frequency domain offset of a first resource block of the first CORESET and a first resource block of the synchronization signal block, where Y is not 0.
To support more flexible deployment, the network may also indicate the first CORESET and the first offset of the synchronization signal block by the "first CORESET configuration and the first PDCCH monitoring occasion configuration". The first offset amount includes: the offset of the first CORESET from the time domain position of the synchronization signal block; the offset of the first CORESET and the PDSCH scheduled by the first PDCCH contained in the first CORESET and the time domain position of the synchronous signal block; a first correlation of a first CORESET with a synchronization signal block, wherein the first correlation comprises: and the relevance relation between the DMRS of the PDCCH transmitted in the first CORESET and the DMRS of the PDSCH scheduled by the PDCCH and the quasi-co-site of the synchronization signal block.
The network may distinguish between frequency division multiplexing and time division multiplexing with a first offset of 1 bit. In practice, whether the first CORESET and the synchronization signal block are frequency division multiplexed or time division multiplexed is only one specific example of the first offset.
The network may also use more bits to indicate a specific first offset. The first offset may be x slots (slots) or x milliseconds. The first offset may be selected from a set, such as 0 offset, 1 millisecond, 5 milliseconds, 10 milliseconds, and the like. Generally, the sync block completes one round of beam sweeping within 5 ms at the longest, so when the first CORESET and the sync block are time division multiplexed, an offset of 5 ms may be indicated. In the second case, when the base station transmits less beams, the synchronization signal block may complete one round of beam sweeping within 1 ms, and when the first CORESET and the synchronization signal block are time division multiplexed, an offset of 1 ms may be indicated. In the third case, the synchronization signal block completes one round of beam scanning within 5 ms, the network reserves the resource of Random Access Channel (RACH) within the next 5 ms, and when the first CORESET and the synchronization signal block are time division multiplexing, an offset of 10 ms needs to be indicated.
The offset set may relate to a Frequency Band (Frequency Range) or a Frequency Band (Band) where the synchronization signal block is located, that is, the offset set is predefined according to the Frequency Band or the Frequency Band.
The network indicates the absolute offset of the starting position of the first CORESET and the system frame number 0 by the "first CORESET configuration and the first PDCCH monitoring occasion configuration". The user equipment derives the first offset by the absolute offset of the start position of the synchronization signal block and the system frame number 0.
In order to reduce signaling overhead, the "first CORESET Configuration and first PDCCH monitoring occasion Configuration" indicates the first association relationship jointly with a Synchronization Measurement Timing Configuration (SMTC). Specifically, the "first CORESET configuration and first PDCCH monitoring occasion configuration" merely indicate whether the first CORESET and synchronization signal blocks are frequency division multiplexed or time division multiplexed. If the "first CORESET configuration and first PDCCH monitoring occasion configuration" indicates that the first CORESET and the synchronization signal block are time division multiplexed, the base station indicates the first offset by the synchronization signal measurement window length in the SMTC, i.e. it is illustrated that the first CORESET is transmitted immediately after the SMTC.
Similarly, the base station may also indicate the second PDCCH monitoring occasion and the second offset of the synchronization signal block through the second CORESET configuration and the second PDCCH monitoring occasion configuration, which may specifically refer to the above description of the first CORESET configuration and the first PDCCH monitoring occasion configuration, and is not described herein again.
